PUMP-TYPE LAUNDRY WASHING MACHINE

Abstract

This invention is a vertical machine for washing and wringing clothes by mean of a closed pumping circuit which supplies the washing or centrifuging system. The washing system uses a special eductor which produces a cavitation effect above the clothes, combined with a rotary washing system which produces the paused circulation of the clothes; the rotation of the washing system is produced by the same water flow. The centrifuging is made in the inner tub impelling its rotation by means of a turbine, thus the tub rotates over the virtual axis which passes through the center of gravity thereof and the clothes for being wringed, furthermore is used a special annular chamber for auto-balancing. The rotation of the tub over the virtual axis is achieved making float the inner tub by means of the special supports which combine the speed components of any point of the tub. The basic ideas of the above concepts are applied in different practical versions, as well as with modifications to a horizontal axial axis or front-loading washing machine or an industrial washing machine.

Description

BACKGROUND OF THE INVENTION

The current vertical washing machines of clothes use agitators, either of the oscillating type or propeller type, to scrub the clothes and produce streams inside the washing tub which pass through the fabric and try to loose the particles adhered thereof; but these streams are not stronger and effective to go through the innermost fibers of the threads, therefore the time of washing can be more prolonged and to spend more energy of the necessary. These washing machines require mechanisms of machined transmission and speed reduction to produce the oscillating motion of the agitation impeller or in the case of propeller thrusters; these tend to entangle so much the clothes. In addition, during the wringing of the clothes by centrifugation, the tub rotates supported by a fixed central axis; this makes difficult the balance during the rotation.

This invention is an improvement to the U.S. Pat. No. 5,953,939 registered by the authors of this in the United States of America. The purpose of this invention is to improve the machines for washing, rinsing and wringing clothes; in addition to take advantage in some way the phenomenon of cavitation for a more efficient washing. The invention is referred to a machine for washing clothes by means of a recirculation pumping system, which uses a special eductor to produce cavitation inside the washing tub and, for the wringing it has a self-balanced rotation system which makes that the tub turns on the virtual axis which passes through the centre of gravity. With these improvements the purpose is to obtain a deeper and uniform washing, to circulate the clothes by the cavitation area inside the tub; besides to decrease the losses of pressure in the hydraulic circuit. Also, as variants, it is showed how to apply all these new ideas to a horizontal or front load washing machine and an industrial washing machine.

In this document are presented the basic ideas of the invention and their variants, with the purpose to combine in the most practical way the most ideal to get a washing and wringing machine which increases the efficiency and speed of washing, and saving time and energy during its operation.

DESCRIPTION

In the following description and in the attached drawings the characteristics of the invention are detailed, indicating the portions of this one with the same reference signs as in the description as in figures; the portions with equal function on the different figures are marked with the same number in each of them.

FIG. 1 represents a first version of the washing machine, in which is described, in general, the recirculation pumping system which is used for squirting inside the washing tub and propelling a turbine which, by means of a speed reducer, it moves a rotary washing system which produces the circulation of the clothes inside the washing tub. Furthermore, it is showed the centrifuging which makes rotating the floating tub on the virtual axis passing through its center of gravity. By simplicity, the eductor system is not showed.

FIG. 2 shows a special eductor and a rotary washing system which is impelled by a jet reaction; this jet is sent towards a dragging zone to push the clothes inside the tub.

On FIG. 3 is observed a first version of the use of the rotary washing system of FIG. 2, as well as a first form to arrange, staying fixed on the system, the special eductor and the steam chamber which feeds it to produce steam bubbles which produce cavitation in the bosom of the washing tub.

FIG. 4 is a variant of the rotary washing system of FIG. 3, used to reduce friction losses in the pipeline. In this version, The eductor rotates along with the rotary washing system, while the steam chamber remains fixed, therefore it is inserted a rotary sealing system, mechanical-type seal, on the tube which carries the steam between the static steam chamber and the suction of the eductor rotating.

FIG. 5 is other similar system to the previous, in which the steam chamber and the eductor rotate together to avoid the use of a rotating seal, besides employing a planetary reducer to transmit the rotation to the system.

FIG. 6 describes a mechanism so that the rotating of the washing system being paused.

In FIG. 7, the feeding to the rotary washing system is made below of the tubs. In this case, the rotary washing system moves laterally together with the centrifuging tub, during this cycle; therefore FIG. 8, as continuation of FIG. 7, shows mechanisms to allow the displacement in the case of using a speed reducer.

On FIG. 9 the same system of FIG. 7 is showed, except that in this figure the rotary washing system remains centered with the geometric axis of the washing machine and the steam chamber is fixed.

FIGS. 10 and 11 describe a system for better balance of the centrifuging tub.

The FIG. 12 is a mechanism, in addition to the flotation system, to support the tub during the centrifuging cycle in its free rotation, on any virtual axis passing through the center of gravity of the tub and the clothes for wringing.

FIG. 13 is a variant of FIG. 7 or 9, which uses the support of FIG. 12; and a pump is used for the washing pumping circuit and another pump for centrifuging cycle; both pumps impelled by the same motor.

On FIG. 14 is showed a system to eliminate loose threads coming out of clothes.

On FIG. 15 is illustrated how to implement the new washing and centrifuging system described in the previous figures, in a new washing machine of drum or cylinder type or horizontal axis or frontal load type cylinders.

FIG. 16 is equal to FIG. 15, except that the washing system changes a little.

On FIG. 17 is used the basic idea of FIG. 12 to the case of FIG. 15 or 16; and FIGS. 18 and 19 are variants of the same idea applied to a washing machine of vertical axial axis as of FIG. 7, 9 or 13.

On FIG. 20 or 21 is used the system of FIG. 18 or 19 for a version of the washing machine of FIG. 3 with less losses.

The FIG. 22 is an industrial washing machine for washing large quantities of clothes, and FIG. 23 is the wringing system of the washed clothes in the system of FIG. 22.

FIG. 24 is a second version of the industrial machine of FIG. 21 in which the wringing is made by centrifuging the clothes.

FIG. 25 is a version of FIG. 9 and FIG. 26 is an optional system of a planetary speed reducer which produces an oscillating motion which put together the blades to produce the circulation of the clothes inside the tub.

The FIG. 27 is an industrial version similar to FIG. 25. The FIG. 28 is similar to FIG. 9.

Support structures, controls, cabinet, etc., for simplicity are not showed in the figures.

Returning to FIG. 1, it is seen that the new washing machine has a main tub (7) within which is placed an internal tub (14) which has about half of the height of that the nodding of the internal tub being when it rotates floating, within the main tub, with the clothes to squeeze seated at its bottom, within the main one. A closed annular chamber (28) forms the side of the internal tub (14) and contains, as a counterweight to balance on the centrifuging cycle, a certain amount of a heavy and fluid material, such as a kind of liquid or small spheres of smooth material. The internal tub is housed in a broadening of the lower half of the main tub (7), so that the diameters of both tubs are sufficiently matched. The peripheral separation between the broadening stage of the main tub and the upper edge of the internal tub is covered to avoid the passage of clothes, by a kind of annular floodgate (31) with section on “L”-shape, whose vertical portion adjusted slightly adjusted to the inner of the main tub; and the horizontal portion is supported by own weight, on the upper edge of the internal tub. The horizontal portion of the “L” has pasted below a plate (30) of antifriction material, which seats and slides on another plate (30) of the same material fixed at the upper edge of the internal tub, when it rotates.

In the center of the bottom of the internal tub (14) it is lifted up a wide vertical tube (11) which terminates, at its upper, in the box of a planetary speed reducer (2) and, through the tub, it is extended downward into another tube (20) to drain the water from the tub. Under the lower end level of the tub, a vertical and axial turbine (26) is within a broadening, on casing shape of the vertical tube (11) so that the turbine shaft (32) impels to the planetary reducer and entering to this through a bearings box (33) with seal against leakage of the lubricant. On the other hand, centered shaft (34) of the reducer output (2) is welded, by above of this one, to the center of the upper lid (35) of a second wide tube or central hollow post (1) hereinafter called central post. This central hollow post is outer, concentric and freely adjusted to the wide tube width (11), also it is hermetically closed only in its upper portion with such lid (35); around this central post are fixed one or two helical plates (4) which to rotate the post they serve as screw, to be pushing the clothes downward. Also are fixed to the central post (1), at the bottom of the tub, radial blades (12), which when rotate through towards the periphery the clothes which are falling to the bottom of the tub. The central hollow post, the helical plate welded to it and the system which makes rotate to both to move the clothes inside the tub, form the rotary washing system, in this figure and following.

The washing and rinsing cycles are made by means of a closed circuit of pumping. The circuit consists of a pump (18) placed under the tubs and with its discharge connected, through the tube (8) and the control valve (13), to a nozzle (6) or a special eductor (not shown in the figure by simplification) which discharged in suitable direction a strong water jet inside the tubs. By the orifices (10), that both tubes, (11) and (1), have at the upper of their periphery, the water flow continuously gets out of the internal tub through central tube (11) and the tube of evacuation (20) to impel the rotation of the turbine (26). By means of the speed reducer (2), the rotating motion of the shaft (32) of the turbine is transmitted, with smaller speed and greater force, to the hollow central post (1) to move the clothes with the blades and the helical plates. The upper of both tubes lacks of orifices and is closed in order to when fill with water the tub a compressed air chamber (3) be formed within them which prevents that the water reaches to the system of the reducer. In order to facilitate more the movement of the clothes, the tubs have in their inner periphery other helical plates (5) which, with the circular motion of the water flow within the tub, cause that the clothes tend to ascend by the sides of the tubs.

The water which gets out of the turbine discharge continues flowing through the tube of evacuation (20) of the internal tub and, getting out of this one, it enters directly to the suction tube (19) of the pump (18) that returns the water flow to those to complete the closed circuit of pumping.

The wringing cycle is carried out through the centrifuging of the clothes. For this, it is started by evacuating the water of the tubs by means of some draining system, not indicated on FIG. 1, until the water level decreases as far as below of the bottom of the tubs, so that the water which is in the internal tub (14) gets out through the retainer or check valves (27) at the bottom of the tub. To finish evacuating the water at such level, becomes to introduce water so that the space between the two tubs be filled until certain predetermined level (29); due to the retainer valves (27) of the internal tub, the water will be not introduced again in this tub, which will be floating in the water that there is between both tubs. The evacuation tube (20) of the internal tub also has a retainer valve (15) with floating plugger, which serves to when introducing again water between the two tubs and during centrifuging the same water it does not enter again for this tube to the internal tub.

Floating the internal tub, this is rotated by means of a special turbine special and similar to a horizontal turbine Pelton-type. This turbine consists of a vertical box (25), of almost cylindrical shape, which is centrally joined at the bottom of the tub or to the vertical evacuation tube (20) and is crossed by this one; at the side of the box are introduced at the half a distributed series of simple cavity-radial buckets (24) slightly tilted downwards with similar form to a ladle curved almost 180°, which allow free way to the inner of the box only through their cavities. Moreover, as it is observed in the cutting AA′, the internal edges of the buckets (24) are directed and finish in a series of holes (21) which the evacuation tube (20) has in its side of that zone, thus the water of the jets that impel to the buckets is discharged by such holes within the tube. These water jets are thrown by a series of nozzles (17) on the cavities of the tangential-shape buckets; therefore the impulse applied on the buckets by the jets produces the rotation of the internal tub (14)

To make work the turbine described on the above paragraph, the control valve (16) of the nozzles (17) connected to discharge of the pump (18). The water flow which impels the turbine is drained by the evacuation tube (20) on the input of the suction tube (19) of the pump (18), so that this same flow being pumped again towards the nozzles (17), and be established the closed circuit of pumping, which keeps the rotation of the turbine. The water which wets the clothes and is centrifuged is evacuated of the internal tub by the holes (9) of the tub which are above of the flotation level. All the system which produces the rotary impulse of the tub is lodged in a cylindrical casing (23) or centrifuged chamber which is centrally joined to the bottom of the main tub (7), as a continuation of this one, and whose bottom is connected to the suction tube (19) of the pump.

Since the internal tub (14) does not rotate supported by a rigid shaft which supports this in its geometric center, this shall rotate, due to its flotation, on the virtual axis which passes through the center of gravity of the set of the tub and the clothes for being wringing. Although the internal tub (14) rotates in balanced form or without vibrations on this virtual axis, if the clothes are not symmetrically distributed inside the tub, the virtual axis displaces from the geometric axis, causing that the tub shakes and oscillates by not rotating on its geometric axis; therefore it may hit or rub with the main tub (7). This undesirable effect is diminished by means of the fluid and heavy material contained in the closed annular chamber (28) which forms the side of the tub (14), since when beginning to rotate the tub the liquid within this chamber is accumulated from the side opposed to the slipping of the virtual axis respect to the geometrical. When the weight of the accumulated fluid in a side of the chamber counteracts to the unbalanced weight of the clothes in the opposite side, the distance between the virtual rotary axis and the geometric center will decrease, although it will not be null and it will be in an intermediate point, since when approaching to these axes it is redistributed, until certain point, the fluid inside the balance chamber (28), but improves the oscillation and the shaking. Between the sides of the tubs are placed bearings with shock absorbers, not shown in the figure, to support frictions and small impacts between the tubs. Later on, some methods are indicated to avoid the redistribution of counterweight fluid.

So that the flotation of the internal tub inside the main tub be stable, is added a flouting counterweight (22) in the lower end of the evacuation tube (20); in this form the meta-center keeps fixed between the flouting centre and the center of gravity of all the system of the internal tub, including wet clothes.

FIG. 2 illustrates a rotary washing system, similar to that described in the above figure, which uses the impulse of a jet reaction to rotate the central post with its helical plate, in such a way that the rotation of the post is combined with a positive push of the same water squirt upon the clothes, in order to cause its movement into the tubs and its circulation through the area where cavitation occurs. In the same drawing is described the aforementioned special eductor.

In the upper portion of FIG. 2 the device is observed de device to produce the positive push on the clothes, which consist of a dragging zone of the clothes limited by two warped surfaces, (44) and (45), separated to some distance facing each other, with opposing curvatures and certain convergence degree between both; in such a way that the clothes, which are in the limited space by both surfaces, can undergo a push or effective drag by a water jet that flows between both surfaces in direction of the convergence and which gets out of a nozzle, a tube or from the eductor illustrated in the same figure, as a jet producer in this case.

Also in the upper portion of the figure it is seen that the special eductor is comprised, firstly of a conical tube or Venturi (39) fed by a tube (40), which increases the speed and lows the water pressure to a negative pressure. The outlet end (41) of the Venturi, of smaller diameter, is enclosed and surrounded by a small closed cylindrical box or suction chamber of the eductor (37) communicated, through a small suction tube (38), with the upper portion of a closed chamber (57) (FIG. 3), described later, where low pressure steam is generated. The suction chamber (37) ends in an output tube (36) with an equal diameter to the final outlet diameter (41) of the Venturi and aligned with the output of this one; in order to absorb the steam there is a very small clear (42) between the final extreme (41) of the Venturi (39) and the initial extreme of the output tube (36). The output tube (36) of the eductor has in its beginning a short and small internal contraction that form the throat (43) of the eductor and then it keeps its normal diameter at full length, to keep the vacuum pressure produced by the Venturi and the throat, contrary to a normal eductor which ends in a diffuser. The water fed by the tube (40) to the Venturi (39) of the eductor and the steam sucked by this from the steam chamber are launched by the output of the eductor (36) in a jet of water mixed with steam bubbles a vacuum pressure, which collapse due the atmospheric pressure to be discharged into the tub, causing implosions and shock waves which wash the clothes.

In the bottom of FIG. 2 is showed the system that produces the impulse to rotate the center post (1) with its helical plate (4), by the jet reaction in a rotary tube (48) fed by the fixed tube (8) connected to the pump discharge. To the left of the bottom of the figure it is observed a first type of rotary coupling between these two tubes, which allows the rotation of the first one over the second one, consisting in introducing some distance to the end of the feeding tube (8) within the rotary tube (48), with a fine adjustment between both, as a sleeve bearing. The axial displacement between both tubes is limited mounting on the fixed tube (8) a shoe of sliding (52), in disc shape with smooth surfaces, which is linked or slightly imprisoned between a pair of discs or rotary plates, also with smooth surfaces, which are joined or linked to each other in their periphery. The upper plate (51), with a bushing slightly fitted to the fixed tube, it supports the rotation of the system on the upper surface of the shoe of sliding (52) and the lower plate (50) is joined to the rotary tube (48), in order to support it.

Another version of the rotary coupling between the fixed tube (8) and the rotary tube (48) is illustrated in the drawing to the right of the previous version. In this case, the fixed feeding tube (8) ends in a cylinder (54), wide and hollow, which at its inner has screwed the external diameter of a large bushing (53), which serves as a sleeve bearing to the rotation of the rotary tube (48), for which the upper end of this tube is introduced within the bushing with a fine adjustment. This bushing (53) is smoothly fastened, in its inferior face, by a shoe of sliding (52) mounted on the rotary tube and, in its upper face, by another screwed bushing (55), as a nut, in the end of the same tube.

In the left inferior portion of FIG. 2 it is observed that the vertical and centered rotary tube (48) within hollow post (1), has in its lower end a first (46) fold to 90° and it continuous, after to get out by a hole at the post, with a second (47) horizontal fold, also near to 90° which places to the end (40) of exit of the tube on perpendicular position to the rotary axis of the own tube, and some distance from this axis and directing the water jet which launch by such end towards the dragging area, formed between the surface (44), terminal of the helical plate (4), and the surface (45) of another inferior plate welded to the same central post (1), in order that the water jet drags the clothes which pushed by the rotation of the helical plate, they gradually stay on this space.

The distance and perpendicular direction with respect to the axis of the rotary tube (48), with which the water jet gets out by the end (40) of the same tube, according to their folds to 90°, it causes that this jet, by reaction, pushes the end of the tube backwards and impels the rotation of this. The transmission of the rotation of the rotary tube to the central post can be directly done, joining with arms (49) the post to the rotary plate (50) of the tube, or by means of a speed reducer to increase the torque and to reduce the speed of the central post, so that the helical plate (4) is moving the clothes towards the dragging zone.

The FIG. 3 is a washing machine by recirculation pumping with washing and centrifuging systems similar to those described in FIG. 1, except that the rotary washing system is impelled with a tube which rotates by jet reaction, as the described in FIG. 2; in addition, it is showed the use of the special eductor in the rotary washing system and the disposition of the steam chamber (57) which produces this to negative pressure. In this case the steam chamber and the eductor remain fixed, joined to the feeding tube (8), to be able to directly connect the electrical power to the resistance (56) that heats the water in the steam chamber and feeding directly the produced steam to the suction chamber of the eductor. At the bottom of FIG. 3, it can be seen an amplification (67) of the eductor and the steam generating system, which are indicated with the same number (67) at the upper of the tub (7).

The feeding tube (8) for the washing centrally gets into the inner of the tubs, (7) and (14), by above of these, and it is directly connected with the conical tube or Venturi (39) of the special eductor, in such a way that this together with its suction chamber (37), crosses and keep centrally lodged inside the steam chamber (57). The steam chamber is a cylindrical box, hermetically closed and lodged within the central post (1), wherein the water is heated by means of the electrical resistance (56) to generate steam to the low pressure of the eductor; this steam is suctioned by the suction chamber (37) of the eductor through the small tube (38) whose nozzle stays at the upper of the steam chamber to draw in only this. Below bottom of the steam chamber (57) protrudes, centrally, the output tube (36) of the eductor to coupling, by means of the support shoe of sliding (52) and the rotary plates (50) and (51) as in FIG. 2 with the rotary tube (48) which keeps the same small diameter of the output tube (36), to keep the high speed and the low pressure of the water and steam flow produced by the eductor, as it was mentioned. Joined by and arms (49), the rotary tube (48) drags in its rotation to the central post (1); furthermore the lower portion and the folds (46) of the same tube are housed within a broadening of the bottom of the central post o cover (58) in bell-shaped, in order to avoid that the clothes stuck with such folds. The end (40) of the rotary tube (48) outstands of the cover (58) by a hole in a radial and vertical plane (66) that interrupts the bell shape, so that the water jet and steam bubbles, which are discharged by such extreme, go towards the dragging area formed between the surface (44) of the helical plate (4) and the plate (45), wherein the bubbles are collapsed causing shock waves which wash the clothes.

Within the internal tub (14) another additional tub is placed (59), separated a little and with a series of holes (10) by which is leaving the water that the tube (40) discharges within the internal tub. Through the space (60) between the bottoms of the two tubs, the water goes out of these through a evacuation tube (20) which begins from the bottom center of the internal tub (14), and it extends downwards until ending very near, upon the input of the suction tube (19) of the pump (18), to complete the closed pumping circuit during the washing cycle.

In order to fix the flotation level (29) in FIG. 3, firstly the water of the tubs is evacuated (62) by means of a small pump (62) which discharges (63) to the general drainage and whose suction (64) is connected to an output (65) of the main tub (7), which is at the side of this to the same height that the prefixed flotation level (29). When the water level comes at the height of the opening (65) cannot be continued evacuating the water and the level (29) of the same one does not get down anymore; in this point, main pump (18) starts and begins to suck, through its suction tube (19), the water of the centrifuging casing bottom (23) simultaneously that it discharges this same water in jets launched by the nozzles (17) upon the Pelton turbine, which begins to rotate and return the water used to the bottom of the casing (23) through the tube (61), coaxial and external to the tube (20), to be re-circulated again by the pump. Since the water passage of the evacuation tube (20) to the suction tube (19) is more direct, this one will suck more water of the inner of the tube (20) that water evacuated by the turbine. Thus, the tube (20) will be emptied at certain volume, same which will go out from the internal tub (14), but it could not retake it due to retainer valve (15) inside the own tube; in this way, the volume of water evacuated of the internal tub increases, in equal amount, the volume of water which there was between the two tubs, therefore the water level between them will increase, exceeding the opening (65). In this condition, the draining pump (62) come back to work removing the excess and repeating the cycle until the internal tub be empty and floats the rest of the cycle.

In the FIG. 4 only it is drawn, by simplicity, a rotary washing system which is a variant of the system of FIG. 3, which is used if the pressure losses in this are big. In FIG. 3 the rotary tube (48) has a small diameter, equal to the output of the eductor (36), which can produce big friction losses due to the high speed of the water in the tube and its curvature. To limit these losses, keeping a big diameter in all the rotary tube (48), in FIG. 4 the eductor is installed on the end (40) of the tube (48), after his double curvature (46) (47), connecting such extreme (40) directly to the Venturi (39) of the eductor.

The cylindrical closed steam chamber (57), which is fixed to be able to feed directly to the electrical resistance (56), is housed within the central post (1) and it is centrally crossed and supported by a passing wide tube (69) which is continuation of the feeding tube (8). The lower end of the wide tube (69) protrudes of the bottom of the steam chamber (57), the enough to be articulated with the rotary tube (48) by means of a rotary coupling with the shoe of sliding (52) linked by the rotary plates, lower (50) and upper (51), as it was described.

The connection between the fixed steam chamber and the suction of the eductor, which rotates with the system, consists of a thin vertical tube (68) which, with its upper end inside the chamber, sucks the generated steam and then it gets into the side of the passing tube (69), in such a way that its lower end stays concentric or coaxial with this tube, and connected to the borehole of a small vertical bushing (70) of thick wall, fixed by means of an arms (73) to the inner of the wall of the passing tube (69). Below the bushing (70) it is introduced in the borehole of this second thin and short tube (76) which can rotate inside the bushing, slightly adjusting its diameters as a sleeve bearing. This second short tube (76) is connected, through a small flexible hose section (72), with a equal third tube (38) which goes down centrally until being placed within the rotary tube (48), wherein it is fastened by a ring (74) fixed to the inner of the rotary tube by another arms (73); then, the third tube (38) goes out from the rotary tube (48) through the wall thereof and it is directly connected with the suction (37) of the eductor. The sealing of the connection between the fixed portion and the rotary portion of the duct of the steam is made with a mechanical or rotary seal comprising a disc (71) or ring that has its upper surface polished and is tightly mounted around the second thin tube (76), which is pressured against the lower face, also polished, of the bushing (70), pushed by a spring (75) which at the lower end is supported against the ring (74) which holds the third tube of steam conduction (38). The flexible hose section (72) serves so that the spring can push the sealing disc. In such a way, the steam sucked by the fixed tube (68) can flow by the tube (38), which turns with the eductor, towards the suction chamber (37) of this. The disposition of the other components of the rotary washing system is equal than in FIG. 3.

As an option, the steam chamber (57) of FIGS. 3 and 4 can be fixed to any other place outside the central post, using a connection tube (38) or (69) with the suction of the eductor of enough length.

The FIG. 5 is similar to the washing system described on FIG. 4 and it shows, in addition, the tubs (7) and (14). The difference consists in that the steam chamber (57) is not static and rotates joined to the rotary tube (48). Furthermore it is showed the planetary speed reducer (2) which transmits the rotation of the rotary tube (48) to the central post (1). The feeding tube (8) also enters by the upper of the tubs and it articulates to the rotary tube (48), of equal diameter, through the already described rotary coupling which comprises a support shoe of sliding (52) and the rotary lower (50) and upper (51) rotating plate. The planetary reducer (2) is centered within the post and above of the rotary coupling between the tubes. The driving gear (79) of the reducer is mounted in a bushing (78), joined at the upper plate (51) and slightly adjusted slightly to the feeding tube (8). The shafts of the other gears of the reducer, which are fixed to transmit the torque forces, are mounted on a round support (80), fixed to the feeding tube (8) which also serves to support the rotation of the post (1) through a bearing system (81).

Below the rotary connection, the cylindrical steam chamber (57) is integrated to the rotary tube (48), thus, the tube centrally crosses the chamber. The rotation of the eductor and the steam chamber (57) together with the rotary tube (48), allows the continuity between the internal tube (68) of the steam chamber and the tube (38) which feeds from this to the suction chamber (37) of the eductor be made with out the necessity of use a rotary seal. The power supply to the resistance (56) that heats the water of the steam chamber is done indirectly, either through a sliding socket connection over the copper or brass rotary rings, as it is described below, or by means of an electric transformer, whose primary is fixed and the secondary, turning with the other components, it feeds to the electrical resistance. Other form to heat the water stored in the chamber is by heat conduction through the walls thereof, placing a heater close to the outside of these walls. These heating systems are not shown in the figure.

As in the FIG. 4, the curved portion, (46) and (47), of the rotary tube (48) and the eductor are confined within the cover (58) which in this case is separated of the central post (1). It is observed that, within the cover, the curved portion of the rotary tube (48) and its end (40), connected to the Venturi (39), increase their diameter, as far as possible, to decrease the pressure losses. The output tube (36) outstands of the plane (66) of the cover (58) directed towards the dragging zone which is formed by the end (44) of the helical plate (4) and the bottom surface of the tub (59). By the front of the exit of the eductor (36) and the dragging zone, the cover (58) has welded a horizontal plate (77) curved upwards (see the cutting of the AA′ section), which serves to the water jet and the dragged clothes being deviated upwards of the tub and the rotary impulse of the water mass of water around the post be broken, so that in the other spaces of the tub the streams being slow and the clothes not be so much ruffled.

The FIG. 6 is a mechanism which controls the paused rotation of a rotary washing system, which uses a planetary speed reducer to transmit the rotation of the rotary tube (48) to the central post (1). The figure only shows a zone of the central post (1), with the rotary tube (48), the planetary speed reducer (2) at the upper and the controlling mechanism at the bottom, with a portion of the bell-shape cover (58).

It can be seen that the mechanism firstly consists of a thick ring of rectangular section (87) or cam ring, concentric with the rotary tube (48) and fastened by a radial arms (49) to the inner wall of the central post (1). The upper surface of this annular plate (87) or cam ring is divided in any appropriate number of sections which comprise, each of them, a low surface portion or valley (89) followed by a slope which finishes in a top or flat crest (88), as cam path. In each section, four in this figure, a corresponding leg (86) with a rounded and slipped end that in whole supported and slipped over each of the paths, by above of a second heavy ring (85). This ring is mounted on the rotary tube (48) and lashed or locked to this by means of a longitudinal wedge (90) fixed to the own tube, in such a way that, with light adjustments, the ring (85) can slide along the tube but not rotate respect to this. The rotation of the second ring (85) and, therefore, from the rotary tube (48) is stopped when the upper face of this ring is pressed against a stopping plate (84) adhered to a no rotary third ring (83). The third ring (83) can be a little raised to separate the stopping surfaces and to release the rotation of a second ring (85) and, consequently, the rotation of the rotary tube (48), of the eductor (2) and the post (1). Thus, the third ring has at the upper an articulated handle to the end of a lever (91), which raises the ring to rotate in its other end over a pivot encrusted on a bar (92) which, passing through the free space of the reducer (2), it is fixed to the support (80) of the gear shafts; thus this disposition avoid, on the other hand, the rotation of the ring (83). To stop of release the rotation of the tube, allowing that the third ring presses over the second or separating to these, the lever moves vertically by a valve rod (93) articulated in the middle portion of the lever and acting by springs and any mechanic system or electromagnetic of control.

By means of the reducer and this mechanism, the paused rotary cycle of the rotary tube (48), coordinated with the rotation of the post (1) and its helical plate, is carried out by the driving frequency of the valve rod (93) and by the relative rotation between the rotary tube (48) and the cam ring (87) which rotates, together with the post, slower than the tube. During this relative rotation, the second ring (85) locate its legs (86) upon the high cam paths and it is pressed against the plate (84) of the third ring (83), stopping its rotation and the one of set. The stopping lasts until that the valve rod (93) raises to the third ring a time to releases again the rotation, which, when continuing, does that the legs of the second ring fall in the low cam path, avoiding the stopping until that the mentioned rotation puts back them into stopping position and the cyclic position of the output tube of the eductor respect to the dragging zone, must be such that allow the paused circulation of all the clothes through the tub, with out entangle so much.

The FIG. 7 is, basically, similar to the rotary washing system of FIG. 5, except that the system is below the tubs (7) and (14), connecting the feeding tube (8) to a passing hole (103) which is at the center bottom of the centrifuging casing (23). Over the passing hole (103) is fixed vertically, as a continuation of the feeding tube (8), a short stretch of flexible hose (102) whose upper end joins a first short and rigid tube (101), staying these two loosely housed inside the draining tube (61) of the centrifuging turbine. This first rigid tube (101) is introduced certain distance within a second tube (100), joined to the center of the bottom of the internal tub (14) and which crossing this, it rises within the tub until a height a little above of the established floating level (29) prefixed of the same tub. This arrangement serves to, without interrupting the continuity of the feeding duct, the second tube (100) and the tub can rotate on the first tube (101) and, at the same time, they move with this one laterally in any direction due to the flexibility of the hose, allowing the rotation of the floating tub around any virtual axis during the centrifuging.

A third tube or rotary tube (48), equivalent to the tube (48) of FIG. 5, is inserted into the second tube (100) by the upper portion of this, until that a ring-shape smooth shoe of sliding (99), which has each of the tubes, settled one on the other to support the weight and rotation of the third tube over the second one.

The aforementioned tubes are introduced one into the other with a fine adjustment, as a sleeve bearing, to allow the free rotation between them and to form, together with the initial hose, the duct to feed the rotary washing system as continuation, with equal big diameter, of the feeding tube (8).

In the FIG. 7 it is seen the upper end of the rotary tube (48) that finishes off and debouch into a closed chamber (97), in form of dome or of a double wall-widen bell, so that the tube (48), gradually opening its diameter, is connected with the inner peak of the bell, which centrally surrounding the tube, it enlarges and unfolds until the tub bottom. Over the upper end of the rotary tube (48) there is a conical appendix (98) which, with the vertex directed downwards, serves as a deflector for the flow which goes out by the mouth or upper end of the tube (48) deviates 180 degrees towards the periphery and the bottom of the double-wall bell, where the same bottom and the two walls of the chamber (97) are extended and converge (see cutting of AA′ section) in such a way that they are molded in a circular exit (107), horizontal and tangential, which is connected with the conical and gradual entry, of a horizontal, curved tube (40) of big diameter matched to the bottom of the bell. As well as in FIG. 5, the tube (40) is connected to the Venturi (39) of the eductor, in such a way that this stays within the cover(58) which is a radial extension of the bell-shape chamber and only the outlet tube (36) of the eductor protrudes through a hole in a vertical and radial plane (66) in which ends the cover, directing the discharge of the water jet and steam bubbles towards the dragging zone formed by the surface (44) of the helical plate (4) and the bottom of the tub (14). In front of the dragging zone is fixed to the chamber (97) a curved plate upwards (77), with the same function described in FIG. 5. The rotary coupling of the tube (48) with the second tube (100) and the water jet discharge, perpendicular to certain distance of the center, by the output tube (36) of the eductor produce a pair of forces by jet reaction which makes rotating the washing system, as it was described. Due to the big section of the bell-shaped chamber (97), the losses by changing the direction of the flow within them are minimal.

In order to feed to the suction (37) of the eductor by the steam chamber (57), rotating both with the rotary washing system, this is placed inside the central post (1) in such a way that the same connection tube (38) of the steam is used to join the bottom center of the steam chamber with the dome center of the bell-shape chamber (97) to make rotate that. The upper end (68) of the connection tube (38) stays within the steam chamber in order to suction this and its lower end (104), welded to the dome, and continues its connection until the suction (37) of the eductor.

At the upper of the steam chamber (57) is welded a shaft (105) which moves the central gear (79) of a planetary speed reducer (2), which transmits the rotation of the chamber to the central post (1). In order to transmit the pair of the impelling shaft (105) it is necessary that the shafts of the others intermediate gears (96) be fixedly supported respect to the system; but, on the other hand, all the rotary washing system must be able to move in any lateral direction according the internal tub moves while centrifuging. Over the reducer (2), is placed a round plate (80) which supports such shafts, and it is joined by above, to other upper plate (95) fixed to the structure (94) of the washing machine by a flexible tube (106) which supports the twist, in order to allow, with out rotating, the lateral displacement of the support plate together with the rotating system. In addition, the plate (80) registers the rotating of the upper end of the impelling shaft (105) in a central bushing and, at its periphery, the rotation of the central post (1). The power supply which in this figure appears within the flexible tube (106), to the resistance (56) of the steam chamber is detailed in FIG. 8.

The FIG. 8 is an amplification of the upper portion of the central post (1) of FIG. 7 and shows two variants more of the system which allows the lateral displacement of the support of the shafts of the speed reducer (2). As in the previous figure, these variants have a round plate (80) which supports the shafts of the gears (96) of the reducer and also it registers the rotation of the impelling shaft (105) and of the central post (1).

Before continuing, it is taken advantage of FIG. 8 to describe the power supply to the resistance (56) of the steam chamber (57) (FIG. 7). The support plate (80) extends upward in a box (108) within which are mounted two rings of copper or brass (109), electrically isolated at the end of the driving shaft (105) joined to the steam chamber. Each ring (109) is connected to a terminal of the electrical resistance (56) by wires, sealed within an axial hole (not illustrated) in the same driving shaft (105) until the resistance (see FIG. 7). The electrical energy is fed by brushes (110) which slide on the rings (109) during the rotation.

Over the box (108) of the support (80) of the shafts, it is centrally fixed a horizontal bushing (111) inside the one that freely slides a round bar (114), in whose ends are welded, perpendicularly to them and centered, other round bars (112). Each of these two bars freely moves in their turn within set bushings (113), one on each side of the bar, which are joined to a plate (95), fixed to the structure or lid (94) of the washing machine. In summary, the mechanism consists of fixing the box (108) of the support (80) to a first track to slide, which allows to move it along a shaft, and this first track to slide is fixed to another similar track to slide which moves in perpendicular sense to the first one, therefore the device, combining both perpendicular displacements, allows to the support moves in any lateral sense, but not rotate.

At the right bottom of FIG. 8 shows one third variant of the system that holds the supported plate (80) so that this can move laterally, combining a linear movement with another angular. Over the support box (108), a horizontal round bar (114) is introduced within a bushing (111) that can slide freely through the bar and articulated rotate to a vertical bolt (118) fixed at center of the box; furthermore, an end of the bar can rotate on another bushing (116) articulated to another vertical bolt (115) fixed to the structure (94) of the washing machine. To avoid the tendency to rotate of the plate (80) and its box (108), are placed a bumper (117) on the box (108), so that when beginning to rotate the plate this bumper blocks the rotation with the bar side (114).

The FIG. 9 is a washing machine equal than FIG. 7, except that the steam chamber (57) is fixed and can be placed outside the rotary washing system which remains centered with the geometric axis of the washing machine, without moving with the internal tub (14) during the centrifuging cycle.

As in the FIG. 7, the feeding tube (8) is connected with the central passing hole (103) drilled in the background of the casing of centrifuged (23) and on this hole it is fixed directly, onto a shoe of sliding or base ring (120) of smooth surface, a first short tube (101) as continuation of the feeding tube (8). In this case, the short tube (101) is introduced, with sleeve bearing fine adjustment within the third rotary tube (48) described in FIG. 7, in such a way that this one can freely rotate over the short tube, supporting its shoe of sliding or lower smooth ring (99) over the base ring (120), to support the rotation and the vertical thrust of the washing system. As passageway so that the rotary tube (48) is introduced into the internal tub (14) and finishes off within this in the bell-shape chamber (97), a second tube (100) rises from the center of the bottom of the inner tub (14) up to one height greater than the flotation level (29), to avoid the entrance of the water to the tub during the same flotation. The second tube (100), opposite to the same tube of FIG. 7, does not fit to the other tubes and it must be of such diameter that it keeps enough clearance between it and the rotary tube (48) and equal clearance with the inner wall (119) of the bell-shape chamber (97), so that the tub (14) and the same second tube (100) can laterally move during the centrifuging, with out collide with the chamber or with the rotary tube.

The conduction of the steam from the fixed steam chamber (57) to the suction chamber (37) of the eductor is made firstly by means of a thin tube (68), which connects the upper zone of the steam chamber with the inner of a closed box (108) within the central post (1). This box serves for the passing of the steam to a second vertical thin tube (38), whose upper end is introduced, with smooth adjustment, into the closed box across a central bushing below the same box, since having its lower end (104) welded to the centre of the dome of the bell-shaped chamber (97) the tube (38) must rotate over the bushing and at the entrance of the tube (38) a rotary seal is placed to avoid leaks. The connection of the steam is completed through another thin tube or hose connected between the lower end (104) of the second thin tube and the suction chamber (37) of the eductor. In the second tube (38) is mounted the input gear (79) of the planetary reducer (2) and the support (80) of the shafts thereof, integrated to the passing box (108), it is fixed to the lid (94) or the machine structure. In such a way the thin tube (38), in addition to carry the steam to the suction of the eductor, it serves as impelling shaft of the speed reducer and as shaft which support the upper of the rotary washing system, which rotates centered and does not require of the mechanisms described in FIG. 8.

The FIG. 9 also shows another system to fit the flotation level (29) of the tub before the centrifuging. The system consists of a closed container (126) which has a volume equal than the water volume which is between the two tubs and the flotation level (29), excluding the free volume within the centrifuging casing (23). Below the closed container (126) there is a small draining pump (62) which connects its input or suction (122) to the bottom of the main tub (7) through a valve (121) and its output or discharge (124) to the lower end of the closed container (126) through another valve (125). Additionally to this first connection, it is added another pair of tubes with their control valves (123) which connect the suction and the discharge of the pump, by exchanging the initial connection between these with the tub and the closed container, respectively. At the top, the container (126) has a tube (64), with its control valve (127), which connects it to the output (65) of the main tub (7) on the flotation level (29); moreover also having a waste-pipe (63) to drain it to a high level.

After the washing or rinsing cycles and keeping closed the valves (123) the draining pump (62) is started with the valves of the first connection, (121) and (125) opened in order to evacuate the water of the tubs until the level of the lower end of the main tub (7), transferring it to the closed container (126); in such a way that the excess of water which passes over the volume of the container is evacuated by the waste-pipe (63) to the general drainage and only remains, therefore, in the container (126) the necessary volume to fill again the space between the tubs at the flotation level. When the level of the extracted water becomes below of the bottom of the internal tub (14), the retainer valves (27) of the bottom of this open and allow the exit of the remaining water thereof. After emptying the tubs, the valves (121) and (125) of the initial connection are closed and are opened the two valves (123) of the second connection, so that the water flow is inverted between the container and the tub, in such a way that all the water stored in the container (126) is returned to the main tub, so that the water level between the tubs reaches the prefixed flotation level. When the water, which is returning to the main tub (7), reaches to the bottom level of the internal tub (14) the retainer valves of this one are close and avoid that the entrance of water to the inner thereof, thus, this tub stays floating to start the centrifuging. With the opened valve (127), the excess of water from the squeezed clothes, which comes out of the internal tub, is drained by output tube (64) at the side of the main tub towards the closed container (126), keeping the flotation level (29).

FIG. 10 is amplification, for better clarity, just of the lower part of the tub (7) and of the tub (14) with their central tube (100) and the balancing chamber (28), of FIG. 7. This chamber, as variant of the chamber of FIG. 1, not only includes the first annular portion (28) of the flank of the internal tub, but also it continues in a second portion or cylindrical cavity (129) below of the basis of this tub, in such a way of double bottom crossing by the central tube (100). The annular portion (28) of the chamber is divided by vertical plates (128) in a series of cells, opened and communicated by below with the second portion of the chamber (129). These vertical cells are of two types, both alternately distributed from the side of the tub.

Each cell (133) of the first type is divided in two portions by means of a horizontal plate (130). The upper portion is separated of the rest of the chamber by the plate, forming a compartment (131) which has a series of holes (10) in its inner wall and another series of holes (132) by above of the flotation level (29), in order to not affect this one, in its outer wall; thus, the first type of cells serves to evacuate from the internal tub (14) the recirculation of water flow. The lower portion of these first cells (133) has the same function as the second type of cells. Within the compartments (131) can be placed filters.

The cells of the second type (134) lack of holes and they are directly communicated to the double bottom of the tub (129), which stores, when the tub is not rotating, the fluid and heavy material which serve as counterweight to balance. If the clothes are not distributed when the tub is rotating the virtual rotary axis, which passes through the center of gravity, it will move at certain distance of the geometrical axis of the tub towards the overweight is, in such a way that the cells diametrically opposed to the overweight keep with a greater rotation radio that the cells closed to the overweight, provoking the tendency by the centrifuging force, that the counterweight flow enters in greater amount into the opposed cells than the closed to the overweight. To is increase the balance of the tub by this distribution of the fluid and however that, for the same reason, the virtual axis moves to coincide with the geometrical axis, the flow trapped in each of the second cells (134) could not be redistributed in the whole annular chamber as in FIG. 1, since the separating plates (128) of the plates impede it to do it, which allows to continue keeping the initial balance.

The FIG. 11 shows only the lower zone of the main tub (7) and of inner tub (14) of FIG. 10, making greater vertical scale than the horizontal, in order to describe more clearly a mechanism which is added to the balancing chamber of FIG. 10 to improve the performance of this same. The mechanism is housed at the second horizontal cylindrical portion (129), centrally crossed by the tube (100) of the chamber (28) and it works obstructing the passing of the balancing fluid towards the cell of the second type (134) from the overweight side by compensating and allows this passing towards the cells of the opposite side. Inside the cylindrical cavity (129) of the balancing chamber, there is a horizontal bar (135) with a ring (138) at its center slightly adjusted to the diameter of the support tube (100) which serves as shaft so that the bar rotates respect to the geometrical center of the tub. At a side of the bar (135) is mounted a small counterweight (136) which can slide over the bar and whose sliding towards the end of this one is limited by a spring (137), which works to compression with little force. Near the entrance of the cells, the other end of the bar is joined to the center of a light and vertical plate (139), which has a width, a curvature and a length such that obstructs the passing of the fluid towards some cells.

If the weight of the clothes is asymmetrically distributed when the tub starts to rotate, the geometrical axis of the tub or the passing tube (100) and, therefore, the bar (135)) together with its central ring (138) will rotate around the virtual rotary axis which is displaced to certain distance from the geometrical axis; by the above, the centrifugal force applied to the counterweight (136) will cause that the bar rotated on its ring (138) until that the counterweight (136) stays diametrically opposed to the virtual axis or to the clothes counterweight, compressing the spring (137) to go towards the end of the bar. In this position the obstruction plate (139) covers the entrance of the balancing fluid to the cells of the second type (134) of the side where the overweight is, until the fluid which goes into the opposite cells compensates the weight undistributed. As the weight is balanced within the tub, the virtual rotary axis approaches to the geometrical axis and the centrifugal force on the counterweight (136) is annulled to coincide both axes; at the same time, the counterweight (136) stops to compress the spring (137) and it is passed, pushed by this, towards the center to its initial position; this movements provokes, by the conservation of the angular moment, that the counterweight (136) the bar (135) and the obstruction plate (139) tend to increase their rotary speed rotating faster than the tub, so that the position, with respect to the cells, of the bar (135) and the plate (139) is indifferent and the rest of the balancing fluid is uniformly distributed in them.

The FIG. 12 is a mechanism which supports to the internal tub during the centrifuging, coincide or not its virtual rotary axis of rotation with its geometric axis. It is considered the speed of any point of the tub is equal to the speed of the point respect to the geometrical axis of the tub plus the speed of this axis respect to the virtual axis.

In this figure only is showed the zone of the lower portion of the tubs, main (7) and inner (14), and the new mechanism which supports to the internal tub. The first portion of the mechanism consisting of a platform (146), centered under the internal tub (14), which has a central hole which is loosely cross over, by a guiding tube (145), which is joined to the tub center, below its bottom. The rotation and the weight of the internal tub are supported by a circular tier or series, concentric with the tub, of vertical wheels (143) with shafts fixed to the platform and directed in a radial form to the center of the tub. Other series of horizontal wheels (144), with their vertical shafts also fixed to the platform, are distributed around the periphery of the platform hole, in such a way that the wheels, supporting their rotation on the surface of the guiding tubes (145), keep and guide the concentric rotation of the internal tub (14) respect to its geometrical axis and to the platform (146). The speed of any point of the tub due to this rotation, concentric to the geometric axis of the tub, constitutes the first component of the absolute speed of the same point.

The second portion of the mechanism allows that the platform moves freely in any lateral direction; for this a series of supports is placed under the platform to sustain it. Each support consists of a horizontal bushing (147) with a round bar (141) of certain length within it, over which the bushing slides freely as sliding track; the bushing can transversely rotate to its geometric axis on a vertical pivot (148) fixed to the platform below this one, at the same time that the bar (141) can move horizontally and angularly, rotating over one of its ends welded to another bushing articulated to a vertical pivot (142) anchored this on the bottom of the main tub (7). So that each of the bars (141) did not support in cantilever the weight of the tub which transmits to it its sliding bushing (147), at the other end of each bar, opposed to the rotation, it is mounted a vertical wheel (140) with its collinear shaft to the bar and from such diameter which rolls tracing a circle supported over the bottom of the main tub (7), when the bar moves angularly. The combination of the linear movement of the sliding bushing (147) on the bar (141) and the angular displacement of these over one of their ends, it gives freedom to the platform (146) to displace in its horizontal plane in any lateral direction, without rotating.

Another form to support the lateral displacement of the platform (146) consists holding this to a first sliding system which moves in certain horizontal direction, being this first system fastened in its turn to a second sliding system fixed to the main tub, which moves also horizontally, in a perpendicular direction to the first system.

The second portion of the mechanism described in the last two paragraphs, in any of its two versions, allows that the platform (146) supporting to the internal tub, and carried or driven by this same, moves horizontally, tracing a circle equal than the circle that trace the geometrical axis of the tub around any virtual axis on which rotates the tub. This movement of the platform provides to any point of the tub the second component of the total speed, with which such point moves respect to the virtual axis over which the tub rotate.

The FIG. 13 is the same washing machine than in FIG. 7, except that the mechanism of FIG. 12 is added to support the rotation of the internal tub (14). In addition, are used two centrifugal pumps coupled to the same submersible motor (150), which are within the centrifuging chamber (23) supported by a plate (152) which hangs from the platform (146) of the same supporting mechanism from FIG. 12.

One of the pumps (149) directly feeds the jets of the nozzles (17) which impel the special turbine Pelton, whose box (25) is joined to the guiding tube (145) from the lower end of the tub. The feeding tube (8) connected without a valve to the discharge of another pump (18) is inserted directly, with smooth adjustment into the passing tube (100) of the tub over which rotates the tube (48) of the same rotary washing system from FIG. 7. The suctions (19) of both pumps stay directly submerged within the centrifuging chamber (23), where continuously re-circulate the water to establish the two closed pumping circuits. The two centrifugal pumps operate with different rotary direction, with the purpose to operate either the rotary washing or centrifuging system; it is enough to change the rotary direction of the engine or motor in its feeding wires (151), sealed and flexible, activating the performance of a system and deactivating from another one, without the need of use control valves. The engine or motor with two pumps of opposite rotation can be used in the other cases described here.

The FIG. 14 is a device for disintegrating the threads that the clothes loosed and to avoid that they obstruct the performance of the pump (18). The device is mounted within a large diameter tube (159), interposed in the suction tube (19) through a conical tube (155). The device consists of a rotating knife (157) of several blades, mounted transversely in an extension (156) of the driving shaft of the pump, cutting the threads which the water carries against other fixed blade (153), also of several sheets by adjusting the pressure between them with the spring (158) at the end of the shaft. Rotating blades (157) also pressed against a plate (154) below with multiple perforations that retain some threads to be crushed by the blades against the same plate.

The FIG. 15 shows a washing machine of two horizontal tubs and front-loading, similar to the common of this type, in which are applied the new concepts described in the previous figures. As in those figures, the washing machine has a main tub (7) which in this case, is a drum placed horizontally, with a circular, chamfer or conical opening (161) on its front face and within which is placed, centrally, another rotary horizontal drum or internal drum (14). This last drum has multiple perforations (10) and a series of parallel blades (5) internal welded along its side, furthermore a circular opening (168) chamfered on its front face, to introduce the clothing. To contain the water inside the drums, the front opening (161) of the main drum (7) is closed hermetically by a conical periphery cover lid (162) with a sealed gasket.

During the washing or centrifuging, the internal drum (14) should be adapted to rotate within the main drum (7); for this, the main drum (7) has, in the back side and housed towards its inner, a first wide and short tube (174) joined by its rear end to the rear center of the drum, with free passing to the inner of this one; in such a way that this first wide tube remains, with a smooth adjustment, into a second wide tube (175) with its front end welded externally in the center of the rear part of the inner drum (14); thus the rotation of the internal drum (14) is supported on the rotation of the second wide tube (175), as a sleeve bearing, over the first wide tube (174), as a support shaft.

On the other hand, the rotation of the inner drum (14) at its front end is supported on a wheel (167), with conical periphery, which fits in the round opening (168) chamfered from the drum and rotates with this. The shaft (163) of the hub (165) of this wheel (167) rotates supported by a bearing box (164) sealed and joined to the center of the lid (162) of the main drum (7), so that this lid (162), pulls with oneself to the supporting wheel (167) to close or to open, for putting or to removing the clothes. To have an adjustment pressure of the linkage between the wheel (167) and the internal drum (14), the wheel hub (165) internally has a compression spring (166) which supported at the inner end of the shaft (163) pushes to the cube so that the wheel be pressed over the opening of the drum.

Also in FIG. 15 the washing machine works with a pumping closed-circuit which feeds of power to the washing or centrifuging, connecting the pump discharge (18) to each of these two systems and their suction (19) to the lower side of the main drum (7). Due to during the centrifuging, as it will be seen in the figure below, the drums move together with their connection pipes to the pump (18), in these pipes are interposed some hoses (102) with enough flexibility to absorb such movements.

The washing is made, as in prior cases, by a special fixed eductor fed by a tube (8), with control valve (13), connected to the discharge of the pump (18) and with the suction of the eductor connected to a chamber (57) steam generator, also fixed. The back and central connector, from the water flow for the washing is made using a conical intermediate amplification (172), with a deflector nucleus (173) also conical in its center, to connect the feeding tube (8) with the back end of the first wide tube (174) of the main drum, in such a way that this tube introduces the flow inside the inner drum, passing through the wide tube (175) of this. The wide feeding tube (174) is connected and ends centrally, within the inner drum, on the basis of a cylindrical horizontal box (97) which serves to direct the flow towards the input of the eductor; in such a way that the big area of the section from these two components decreases the speed of the flow, and thus, the friction losses by the changes in its direction. So that the water flow acquires a rotary impulse to enter in the cylindrical box (97), it is placed within the first wide tube (174), along to this and until the back side of the cylindrical box, a duct or helical plate (160) which gives this movement to the flow. The flow which is entering to the cylindrical box with such movement is directed, through a volute (176) within the box, towards an output tangential tube (40) in the box periphery. The output tube (40) ends in the Venturi (39) of the eductor, which directs its exit downwards and the most tangentially possible over the blades (5) from the lower side of the inner drum, in such a way that the water jet and the bubbles, colliding against the blades, impulse the rotation of the inner drum to shoveling with the same blades to the clothes, in the bosom from which cavitate the bubbles. The connection between the steam chamber (57) and the suction chamber (37) of the eductor is made by a thin tube (38) which enters, by the wall of the first wide tube (174), towards the cylindrical box and the eductor within this.

In order to make the wringing by centrifuging, in the second wide tube (175) is mounted a common Pelton turbine (170), which is impelled by water jets which collides over the buckets (24) and they are launched by nozzles (17), with control valve (16), connected to the discharge of the pump (18) therefore, thus, the turbine drag in its rotation to the inner drum holding back the wet clothes for wringing. In the front face of the buckets is perforated a small hole (169) in which finish a radial thin duct (171) which is until the inner surface of the second wide tube (175), with the purpose that the rotation of this tube be lubricated with a small portion of the same water which launch the nozzles over the buckets.

The FIG. 16 is a variant very similar to the horizontal washing machine of the FIG. 15 and, as in this figure; the connector of the feeding is the central back part of the main drum (7). In this case the feeding tube (8) is directly connected with the Venturi (39), in such a way that this, the output tube of reduced diameter (36) and the suction chamber (37), fed by the fixed steam chamber (57) through the tube (38), which compose the special eductor, are housed securely fixed within the wide tube (174). This tube is joined to the center of the main drum (7) and serves as shaft of the inner drum (14), which rotates with to the second wide tube (175), like a sleeve bearing, on the first wide tube (174). The output tube (36) of the eductor, which is as short as possible, protrudes slightly from the back of the inner drum (14) and it curves slightly downward in order to launch the jet of water and steam bubbles upon the underside of the drum. The end of the output tube (36) is covered with a disc (58) close to the back side of the inner drum and of rounded surface to avoid that the clothes be hooked with such end.

In this case, the closed pumping circuits for the washing and for the wringing are separated, so that the hydraulic circuit which feeds the eductor is fed by a centrifuge pump (18) which operates with a sense of rotation opposite to the centrifugal pump (149) of the circuit of squeezed, both pumps being driven by the same motor with rotating interchangeable to activate one or another pump. This double pumping circuit has the purpose of to operate alternately each circuit, in such a way that to operate the wringing pump (149), this launch a water jet, through of its tube and the discharge nozzle (17), over the buckets (24) of the Pelton turbine (170) joined to the inner drum to rotate this a little bit and to make the shoveled of the clothes by means of the inner blades (5) of the drum. Then the rotation of the motor is changed to operate the pump (18) and activates the washing action of the eductor, repeating adequately of the two cycles slowly.

The FIG. 17 shows the system which allows to the inner drum (14) of the FIG. 15 or 16 rotate, during the centrifuged, over the virtual axis which passes by its center of gravity. This system is similar to the described on FIG. 12 and is based also in a support, equivalent to the support (146) of this Figure, which support to the tub or inner drum (14) rotating over its own geometrical axis, while the support and the drum move laterally around the virtual rotation axis. In this case, the same main drum (7) has the function of the mentioned support since the inner drum rotates centrally inside the main drum. The system which holds the main drum and allows it to move laterally, in any direction, consists of 4 lugs (177) welded symmetrically to the sides of the man drum (7) in four points, two in front and two at the back. En each lug is articulated, by a horizontal pivot (148), a vertical bushing (147) which can rotate transversally to its geometrical axis over such pivot. Within the bushing it moves, in a sliding track form, a vertical rounded bar (141) whose upper end articulates a pivot (142) which allows to the bar oscillate in angular form, as pendulum, over such end in a perpendicular plane to the axis of the drums. In the lower end of each bar (141) is fixed a spring (178) which supports the weight of the drums supporting the bushings (147) over the upper ends of the springs.

To avoid that the forces of the vertical movement of all the previous supports system of the drums be transmitted to the structure (94) of the washing machine in vibration form, this system in its turn is fastened to another system which consist on fixing respectively the two pivots (142) of the fore oscillating bars (141), and equally in the two pivots of the rear end, to each one of the ends of an horizontal bar (179) in whose middle part is raised a vertical rod (183) are articulated, in rotary form, an end of each of the other two bars (184) which are opposite, each one towards a side of the rod, and sloping downwards with certain angle, as normal position. The other end of each of these two sloping bars, also is articulated in same rotary form, to a corresponding second horizontal rounded pushing bar (182) which runs within a bushing (180) fixed to the structure (94) of the washing machine. The movement in opposite sense of these last two horizontal pushing bars (182) is limited by springs (181). Thus, the force of the motion vertical upwards and downwards of the horizontal bar (179) is projected by the two sloping bars (184) in two horizontal forces, equal and opposite to each other, over the bars (182) and the pushing springs (181) to both sides of the rod; moreover of the little vertical projection of this force just produces pairs o torsion efforts contrary in each fixed bushing (180), in such a way that the forces over the two springs and the torsion pairs over the two bushings are opposite to those from the other side, therefore, the reactions over the structure of the washing machine are equal and opposite, therefore, the vertical motion force is transformed in inner efforts over the structure, annulling as vibration producers.

To decrease the movement of the virtual axis of rotation respect to the geometrical axis of the drum, as in FIG. 1, annular balancing chambers (28) are placed, surrounding each end of the inner drum (14).

The FIG. 18 is a variable of the FIG. 12 to avoid the vibration in the centrifuging, similar to the system on FIG. 17, but applied to a vertical washing machine, in such a way that the main tub can be move laterally to be supported by a special supports system, while the internal tub rotates over its geometrical axis within the main. The washing system is the same of FIG. 7, except that the feeding tube (8) of the eductor enters directly into the main tub (7) fixed to this and adjusted to the inner of the central passing tube (100) of the internal tub (14), in such a way that, furthermore, the tub can rotate over its same passing tube (100) coupled to the Pelton-type turbine (25) and registering its rotation in a bushing (185) that the main tub (7) has in its center. Although it is not required, is convenient that the tub floats so that the weight thereof over the bushing is less.

The mechanism which during the centrifuging allows to the main tub to move in any lateral direction comprises in a series of supports which support to the tub below and around this, similar to the wheels which aligns automatically in the direction of the displacement towards any side. In this case each support comprises a flat horizontal bar (147) which in one of its ends is articulated a bearing of vertical shaft or pivot (148) fixed to the bottom of the tub, which allows that the bar oscillates in a horizontal plane over such end. The flat bar, following the movement of the tub, moves lineally in any of both senses supported over the upper periphery of a vertical wheel (186) whose mounting (141) can rotate horizontally over other bearing of vertical shaft (142), so that the wheel can align in any moment with the direction of the bar. Below of the box which support to this last bearing (142) is welded a guide vertical bar (188) which slides within a support bushing (187) fixed to the structure (94) of the washing machine. Between the bearing box (142) and this supporting bushing (187) is placed a spring (178) which works to compression, as a shock absorber to support the weight of the set in its displacement around of the virtual rotating axis. The vertical wheel (186) always must keep a minimal distance from the pivot or bearing (148) of the bar, with the purpose of that exist a pair which induces the aligning of the bar with the direction of the displacement of the tub in each moment.

On the other hand, the connection pipes, (8) (17) and (19), between the tubs and the pumps (18) (149), have, as in FIG. 17, intercalated a stretches of flexible hoses (102) to allow the lateral movement of the connector tubes together with the main tub (7) respect to the pumps.

The FIG. 19 is a variant of the supports in FIG. 18, therefore, also this new supporting system (189) of the main tub (7) serves so that this can displace laterally in any direction, while the internal tub (14) rotates over the shaft (194), which registers its rotation in the central bushing (185) of the main tub and it is impelled by the afore described turbine system (25).

The new system consists in a supporting series (189) which support to the main tub (7) distributed around its upper periphery. Basically each support consists in a horizontal crosshead of two bars or shaft (191) joined in its center to 90°, in such a way that one of the shafts rotates in its ends over the laterals of an upper inverted U-shape plate (190) welded to the upper portion (187) of the structure of the washing machine through the fixed bar (193). The other crossed shaft rotates also over the laterals of the other lower U-shape plate (192) from which hangs the upper end of a second bar (141) which passes loosely through a horizontal hole practiced in a lug or plate (177) welded to the side of the main tub (7), so that a spring to compression (178), fixed to the lower end of the bar, supports below of the hole of the lug to the weight of the tub. Thus, the combination of the free oscillation or angular rotation in a plane, over one of the shafts of the crosshead (191), of the lower “U” plate (192) together with the bar (141) and the oscillation or angular rotation of these over other shaft of the crosshead, in the other perpendicular plane to the first one, allows that the bar (141) can oscillate angularly in any direction respect to the supporting bar (193) of the crosshead, supporting to the tub in any lateral displacement limited of this. This system is similar, with a different use, to a universal transmission (“Cardan Joint”) of rotation between two shafts no aligned as are the bars (141) and (193).

The FIG. 20 is a vertical washing machine, as in FIG. 3, the eductor and its steam chamber (57) are fixed within the central post, and the input of the feeding tube (8) is by the upper portion of the post. Furthermore, the supporting system (189) of the main tub of the FIG. 19, is used, so that the internal tub (14) can be centered within to that rotating over its geometrical axis or shaft (194) within a central bushing (185); thanks to this and to the stretch of flexible hose (102), the connectors of the pipes (8), (17) and (19) can be fixed to the main tub, in such a way that the washing machine can use the rotary washing system describe as follows.

In FIG. 20, the feeding tube (8), fixed to the main tub (7), penetrates deeply by above within of the central post (1), fixed in its turn to the feeding tube (8), wherein it is connected with the Venturi (39) of the eductor, so that the output tube (36) of this, stays as near as possible to the bottom of the internal tub (14). Through a swivel coupling, with its supporting shoe of sliding (52) and rotary plate (50) as it was described, the output tube (36) of the eductor is articulated with a rotary tube (48) which is short, of the same diameter and this is folded a few grades respect to the vertical. The possibility that the rotary tube (48) be the shortest possible and that its folding be small, allows to have losses by friction minimal on this, in comparison to the same tube of the FIG. 3. The suction of the eductor is fed directly, through the tube (38), by the steam chamber (57) and the electrical resistance within this is equally fed directly.

The central post (19 fixed has two helical plates (4) separated 180° one from the another one and, in the other hand, the bottom (45) of the internal tub (14) is rounded from the center to the periphery, as a middle toroid surface, in such a way that the bottom center raises a conical elevation (198) close to the end of the rotary tube (48); in such a way that, dragging areas are formed between the surface (44) of the endings of the helical plates (4) and the curved surface (45) of the bottom of the internal tub (14). The output of the tube (48) stays tangential to the curvature of the peak of the elevation (198) and placed between this curvature and a small conical deflector (196) fastened around of the lower end of the central post (1). Thus, the water jet and the bubbles discharged by the rotary tube (48) drag the clothes which are in such dragging areas, directing towards the periphery of the tub wherein the current and the clothes, guided by the curvature of the tub bottom, raise by the side of the tubs until the upper portion of these, to later return towards the bottom by the center of the same tubs guided by the helical plates (4) again towards the dragging areas, to be impelled repeatedly by the jet which gets out of the eductor.

The lower part of the FIG. 20 shows, in the detail (195), an amplified of the system that drives the rotating short tube (48). The system consists firstly of a small motor (200), of slow speed, mounted vertically over a plate (199) within the central post (1). The shaft of this motor is coupled through a small pinion gear (201) with the periphery in form of gear of the plate (50) of the rotary coupling between the tubes; in such a way that the plate also functions as gear impels to make rotating the rotary tube.

The FIG. 21 is equal than FIG. 20, except that the connector of the feeding tube is made by the lower part of the tubs. The feeding tube (8) is introduced below of the central part of the casing (23) of Pelton turbine and finish at the Venturi (39), so that this, the suction chamber (37) and the output tube (36) of the special eductor, they stay housed within a tube (100) whose upper end is welded centrally below of the internal tub (14), furthermore to be joined to the turbine Pelton (25). This tube (100), furthermore to be the passing duct of the eductor to the internal tub, also serves as the rotation shaft of this and of the turbine over the central bushing (185) of the main tub, therefore its external diameter is adjusted to such bushing. In reason that the eductor is fixed, the chamber which generates steam (57) also is fixed and it feed of steam to the eductor directly by the tube (38).

To discharge the jet of the eductor within the internal tub, the rotary tube (48) is coupled, as it was described above, to the output tube (36) of the eductor, in such a way that the end of the rotary tube outstands a little of the bottom of the internal tub by the passing tube and it is curved the necessary to discharge radially the jet towards the periphery of the tub; thus, the jet impels the clothes that is in the dragging zone, comprised between the bottom (45) of the tub and the helical plate (44), towards the periphery and upwards of the tub. The length and the curved finish of the rotary tube (48) as small as possible to decrease the pressure losses thereof, therefore it is convenient that the eductor enters within the shaft or passing tube (100), the most as high as possible.

The rotary washing system is complete making to rotate in small pauses to the internal tub (14) together with the central post (1) and its helical plates (4), impelled by the turbine Pelton; for this, the lower end of the post is joined to the bottom of the tub through a thin legs (202) in order to allow the passing of the jet which launches the rotary tube (48). Within the central post (1) is a cylindrical box (80), fastened centrally to the structure (94) of the main tub (7), wherein is housed a motor with speed reducer (200) which, by its centered shaft (201) joined to the rotary tube (48), makes rotating slowly to this so that the jet which discharges radially goes running all the periphery of the tub. In such a way, during the washing cycle, can be alternated the performing of the washing pump (18) with that from the centrifuging pump (149) so that this activates the rotation of the Pelton turbine intermittently, in such a way that the slow rotation of the helical plates combine with the rotation of the rotary tube (48) to facilitate the circulation of the clothes.

The bottom of the FIG. 21 shows with the number (195) the same zone marked with the pointed circle in the above figure, to show that can be added, as in FIGS. 5 and 7, a planetary reducer (2) between the central post (1) and the shaft (201) which move to the rotary tube (48), so that the post transmits its rotation to the rotary tube, without the necessity of use a motor with the reducer (199) to make rotating the tube.

It is evident that the method of FIG. 21 to make rotating the central post together with the internal tub, joined centrally to the bottom of this through two or three legs, can be applied equally to the system of FIG. 20, also activating the centrifuging circuit alternately and in short pauses during the washing cycle.

The FIG. 22 represents an industrial washing machine for big quantities of clothes, which uses the principle of recirculation by pumping and the discharge produced by a special eductor (as the described in FIG. 2) of the steam bubbles to low pressure which implode on the water and clothes bosom, as it was described in above figures.

In this FIG. 22 is observed that the washing tub (7) of this new industrial washing machine consists in a tube, duct or canal of rectangular path or another form, in addition to closed trajectory, of enough length and with corners rounded to make easy the transit of the water and the clothes through these. A special eductors series as those in FIG. 2 comprised each by a Ventury (39), a discharge tube (36) without diffuser and a steam suction chamber (37) fed by the tube (38) from a steam generator or closed container (57) with heated water by a heater (56), they discharge water jets and steam bubbles to low pressure within the canal or duct. These eductors are placed in such manner that along the canal which impelled the water and the clothes within the canal in a closed path around this, allowing the cleaning action of the cavitation of the bubbles over the clothes.

Each Venturi of the special eductor series is fed by the discharge tube (8) of a pumping system in closed circuit whose suction tube (19) of the pump (18) is connected to the canal bottom through a filter (203). Along the inner sides of the canal is placed a sloping-blades series (204) so that this provoke the shoveled of the clothes in order to be changing the relative position of this within the tub.

The FIG. 23, as continuation of FIG. 22, is the wringing system by rollers and rinsing of the washed clothes in the washing machine of FIG. 22. This system consists firstly in a perforated band conveyor (207) placed above the straight portion of the canal which form the washing tub (7); such band is formed by two stretches o portions, so that the structure (205) between the two guide rollers (206) from the initial stretch of the band can be descend in angularly form, rotating downwards and the other portion stays horizontal by above of the tub. Finishing the washing In the tub (7) from FIG. 21, the structure (205) of the initial portion of the band, rotating angularly, is introduced slow and gradually in oblique form within the tub (7) until its bottom, while the water continues circulates along with the clothing. The perforations of the carrier band (207) allow that the water continues circulating while the band retains the clothes and raises them to the final stretch and horizontal of the band which carries until its end where it launches them over the other lower band (208) which take them to introduce between the same band, supported over the guide roller (210), and other wringing roller (209) pressured over the band, to wring the clothes by pressure. The wringed clothes between the band (208) or the roller (210) and the roller (209) is poured within the other tub (211), similar to that of washing, in which is rinsed the clothes by the re-circulating pumping of the water which comprises the pump (18), the suction (19) and the discharge (8) with the nozzle (36).

The FIG. 24 is other version on the industrial washing machine which uses the same washing and centrifuging systems above described to make its work. The main tub (7) is formed by a closed canal in circle of enough size, in such a way that the inner wall of the canal forms a great diameter central cylinder (219) for the easy circulation of the clothes around thereof. The internal tub (14), as in the above figures, serves to centrifuging the clothes, has equal form than the main (7) and it is housed within this with certain separation between them. For the centrifuging cycle, at the upper of the cylindrical body (219) is fixed centrally a vertical motor (218) whose shaft, directed upwards, transmits its rotation to the internal tub (14) by a coupling (215) which fasts, by an arms (216), to the upper portion of the inner wall of the internal tub. On the other hand, the main tub (7) is supported, around its upper periphery, by a supports series (189) equal to those from FIG. 19, which allow it to displace in any lateral direction, while the internal tub rotates, over its geometrical axis, impelled by the vertical motor (218), as it was described. To allow the free displacement of the internal tub (7) respect to the pipes from the pumping system, the pipes connected to the tub have intercalated stretches of flexible hoses (102) as it was indicated in FIGS. 17 and 18.

The washing by means of cavitation is produced, as it was mentioned, by means of a special eductors series whose suction is connected (38) to a steam generator (57), in order to be fed by a re-circulating pumping system of the water into the tub, connecting the discharge (8) of pump (18) to the special eductor and the suction of this (19) to the filter (203) in the bottom of the main tub (7). The eductors point their discharge jets (36) within the tubs in adequate direction and from the upper of these. The feeding tubes of the eductor have a flexible portion (217) in order to can change the direction of the eductor jet during the washing and in order to remove the eductor before removing the small basket described in the following paragraph.

Inside the internal tub is a basket (212) with the same profile or shape of the internal tub, except that it does not have the outer wall and it is fastened by a hollow and central conical body (213), which in dismountable form and of easy registration is coupled to an equal conical prolongation of the motor couple (215). The upper portion of the conical body (213) has an eyebolt (214) which serves to pull up with a crane the small basket and to remove the washed clothes.

FIG. 25 is a variant of the rotary washing system, similar to that from FIG. 9, except that in this figure the balancing system in the centrifuging is equal to that described in FIGS. 19 and 21, with the special supports (189) of the main tub (7), the bushing (185) for the rotation of the internal tub (14) and the flexible hoses (102) intercalated in the connectors of the pipes. The steam feeding to the eductors without diffuser (221) is equal to that described in the FIG. 9, wherein the generated steam in the fixed chamber (57) is conducted by the tube (68) fixed to the closed box (108), in which the steam is transferred to the rotary vertical portion of the central tube (38) which carries the steam. Furthermore, in this case, the rotary tube (38) also serves as impeller shaft of the two planetary reducers (2) and (225) which move the central hollow post which is divided in two portions. The upper portion of the post (224) rotates, impelled by the above reducer (2) in a single sense such as the helical plate (4) joined to this portion pulls to the clothes, as in above figures, downwards. The lower portion of the post (1) rotates oscillatory by means of the double planetary special reducer (225) from below, which operates in such a way that the blades (12) joined to this portion of the post oscillate as a common washing machine. The steam transference to the rotary tube (38) and the operation of the reducers impelled by this tube will be described in detail in the following FIG. 26.

The feeding of the rotary washing system consists of a first great diameter fixed tube (101) which enters centrally below the centrifuging casing (23) and it carries the flow which comes from the pump discharge, in similar form than in FIG. 9. This first tube is introduced into a second tube (100) which gets down, joined in its upper portion to the center of the bottom of the internal tub (14), until support centrally the Pelton-type special turbine (25). By above of the second tube (100) it is introduced into this third tube or rotary tube (48) until this slightly assets by means of a shoe of sliding (99) over another shoe of sliding in the upper edge of the second tube. The first and the third tube are introduced with fine adjustment as a sleeve bearing.

The upper end of the rotary tube (48) is extended gradually in conical form (220) until finish off, centrally and by below, within a closed cylindrical chamber (97) of low height, great diameter and housed in the bottom of the internal tub (14), instead of the bell-shape chamber of the FIG. 9 or 7. To guide better the output of the flow in the upper end of the rotary tube (48) over this is placed a conical appendix (98) with the vertex downwards. The water flow which is coming out from the rotary tube (48) circulates radially within the cylindrical chamber (97) and it is extended gradually within the successive concentric sections of the chamber, which increase their area according they are separated of the center. Thus, the speed of the flow is decreasing in its transit by the conical and by the cylindrical portion; in such a way that the pressure losses by the change in the flow direction are minimal. Moreover, the flow is distributed within a section radial series of the chamber whose walls (222) converge so that (see cutting BB′) each section guides the flow towards an output (107), circular and tangential, connected to the input tube (40) of the Venturi from a respective eductor without diffuser (221), placed in such a way that in the chamber perimeter (97) which its output short tube (36), a little curved, discharges in a convenient and tangential direction water jets and steam bubbles which produce cavitation in the bosom of the clothes and impels, by reaction, the rotation of the cylindrical chamber over a rotary tube (48). Additionally are added in each section a curved and radial plates (223) for better guide of the flow towards the eductors.

The bottom enlarged portion (226) of the vertical portion of the steam conductor tube (38) is fixed centrally above the cylindrical chamber (97) so that the tube rotates with this and it serves as tube-shaft impeller of the reducers, as it was mentioned. On the other hand, the steam carrying towards the suction of the eductors (221) continues by other horizontal tubes (38) which radially are from the lower portion (226) of the vertical portion of the tube.

Since it is necessary for the operation of the planetary speed reducers (2) and (225) that the structure which supports the gears of these stays fixed, a bar (94) joined to the main tub (7) is welded to the steam transference box (108) and which is integrated to such structure.

FIG. 26 shows in detail the system of the two planetary reducers (2) and (225), housed respectively in the upper (224) and lower portion (1) in which is divided the central post, and which produce the rotary movement of the helical plate (4) and the oscillating movement of the blades (12) as it was described in the FIG. 25. Both reducers are impelled by the same vertical and central portion of the tube (38) which also carries the steam to the special eductors, as also was briefly mentioned in such above figure.

As well as in FIG. 9, the supporting structure (80) of the reducers gears is integrated to the box (108) which transfers the steam that is carried by the fixed tube (68) to the upper end of the rotary tube (38) same which enters into the box through a passing hole with mechanical seal (71) to avoid leaks. The box (108) is fastened to the main tub to fix the entire structure (80).

Below the box (108) is the planetary reducer (2) which comprises the central gear (79) mounted on the impeller tube (38) the intermediate gear (96) and the box (244) of the peripheral external gear which, to be joined to the upper portion (224) of the central post, makes rotating to this and its helical plate (4) in a single sense. The reducer rotates supported in the bushings (239) over a tubular rounded portion (227) of the structure (80).

The second reducer (225) which moves to the lower part (1) of the central post really is a double reducer with two systems, aligned one over the other one, of planetary gears (233) and (243); each of these systems has a central gear (235) mounted on a hollow shaft (241), so that these shafts are independent between them and they rotate over the aligned bushings (234). The upper end of the hollow shaft of the above gear and the lower end of the hollow shaft of the below gear, protruding from its bushings, have the radial bars (231). Inside the two hollow shafts or tubes (241) runs a ratchet tube (240) with other bars or vertical ratcheted bar (230) in each end in order they can be interlaced with the radial bars (231). The length of the ratchet tube (240) is such that, moving upwards or downwards, it interlaces by itself with only one of the two hollow shafts (241) of the central gears, keeping free the rotation of the other gear. Within the ratchet tube (240) is the impeller tube (38) which rotates in a single sense and drag in its rotation, by a wedge (237), to the ratchet tube (240), which in its turn impels the central gear to which is interlaced in this moment. The key slot (236 in which is loosely housed the wedge is larger than this, so that the ratchet tube (240) has enough freedom to displace upwards or downwards.

It is observed, in FIG. 26 that in the upper system of planetary gears (233) the quantity of intermediate gears (232) is a non number and in the bottom system (243) the quantity of this gears (242) is a pair number, therefore, to link to the ratchet tube (240), which rotates in a single sense, to one or another system will make that one of them rotates in contrary sense to the other one. Thus in this way as the peripheral gears of the two systems are joined to the lower post (1) this will oscillate to certain frequency together with its blades (12), as it get up or get down alternately the ratchet tube (240). The central post supports its oscillation on bushings (239) which rotate over the tube (227) of the structure (80) at the upper portion and over the tube (38) at the lower part. The upper or lower vertical position of the ratchet tube (240) is controlled by means of a spring (238) and the action of a bobbin (229) over the magnetic nucleus (228) mounted on the ratchet tube (240) or by the cam system.

FIG. 27 is a variant of the industrial washing machine of two tubs of FIG. 24, in combination with the portion of the FIG. 25. In this new version, the main tub (7) is cylindrical, large and has flat bottom, but it configures a circular canal closed together with the shape of the internal tub (14), furthermore, the central connector to the washing system of the feeding tube (8), or of the discharge of the pump (18) from the closed pumping circuit, is vertically for the center of underside of the main tub, so that it is connected with a rotary tube (48), introducing this within that, with slight adjustment as sleeve bearing. In this case, the upper end of the rotary tube (48) finishes in a conical shape and is joined to the bottom of the internal tub (14), moreover, as in FIG. 25, this tube is connected within a cylindrical chamber (97), which feeds to series of eductors (221) without diffuser whose output tubes (36) direct its discharge over a dragging zone, formed this by a curved plates (44) joined to the central body of the basket (212) and the bottom (45) of the same basket which serves to remove the washed clothes, as it was described. The central cylindrical body (219), which constitutes the inner wall of the canal, is joined to the upper portion of the cylindrical chamber (97), which likewise is joined to the bottom of the internal tub (14), integrating a single piece. The supports (189) of the main tub, the steam chamber (57) and the feeding tubes (38) of this to the eductor are the same described.

The rotation of the internal tub (14) in the centrifuging, which is supported in a shoe of sliding over a bushing (185) in the center bottom of the main tub (7), is impelled by a motor (218) whose vertical shaft (245) penetrates axially within the vertical portion of the feeding tube (8) through a hole practiced in the lower portion of a bend to 90° of the same vertical portion of the tube, sealing the passing of the shaft by a mechanical seal (71). The upper end of this shaft is joined to the inner of the lower end enlarged of the rotary tube (48) by radial arms (246) which not avoid the flow passing, so that the motor (218), when operates, impels to tube (48) together with the internal tub (14). During the washing the motor can rotate in opposite sense to the flow circulation within the tub, so that the dragging zone displaces against this flow and improve the circulation of the clothes.

FIG. 28, is a variant of the washing system of a vertical washing machine of two tubs (7) and (14) similar, in part, to the systems of the FIGS. 9 and 25. As in FIG. 9, the discharge (8) of the pump (18) is connected, intercalating in this case a hose (102) between both, with a central fixed tube (101) which enters into the centrifuging casing (23) and is fixed in this, to then crossing the bottom of the internal tub (14) through a passing hole slightly adjusted to the same tube, which raises inside the tubs until close the upper portion thereof. At the upper end of this first tube (101) is introduced a second rotary tube (48), with light adjustment so that it can rotate within the first tube, which is supported by a shoe of sliding (99) over other shoe of sliding at the end of the first tube. It is observed that the system does not use a central hollow post. In the centrifuged the centered rotation of the internal tub (14) within the main tub (7) is performed on the bushing (185), and to avoid the vibration is used, for instance, the same system support (189) of the main tub of the FIG. 20 or 21.

The upper end of the rotary tube (48) finishes to the inner of a widen bell-shape closed chamber (97) of double wall, in a same shape and with the same function that the similar chamber showed and described in FIG. 9, except that, in this case, the periphery of the bottom of such chamber (97) is connected by convergent surfaces, to the inputs of a series of Venturi tubes (39) belonging to the special vertical eductors without diffuser, whose output tubes (36) discharge downwards water jets and steam bubbles which cavitate in the bosom of the clothes, generating currents which drag the clothes and which, guided by the curved bottom (45) of the internal tub, they follow closed paths on vertical planes from the center to the side of the tub and all around this. It is observed in the figure that the eductor series (39) are slightly deviated from the vertical a same angle, with the purpose that the small horizontal component of the jets reaction which get out by the output tubes (36) impel, over the rotary tube (48), the rotation of the chamber and the eductor around the tub.

Additionally, to help the circulation of the clothes within the internal tub (14), in the bottom of this, are fixed the radial blades (12) which rotate with the tub when the pump (149) is activated which feeds (17) the jets which impel the Pelton turbine (25) of the internal tub at the centrifuging cycle, as it was described. This action is made in short periods during the washing, alternately with the performance of the pump (18) of the hydraulic circuit of the same washing; in such a way that in this short periods, the clothes which are in the tub bottom are impelled by the rotation of the blades (12) towards the periphery, pushing and provoking the movement of all the clothes within the currents produced by the eductors.

Finally, the steam feeding to the eductor is made in similar form to that described in FIG. 9. On the cupola center of the bell-shape chamber (97) is fixed a closed box (108) for the steam distribution by means of a tube series (38), connected to the inner of the same box, and which carries the steam to each of the suctions of the different eductors in which finishes the bell-shape chamber (97). In its turn, the closed distribution box (108) is fed by a tube (68) which enters into the box, by above, through a center bushing and adjusted to the tube, so that the box can rotate over the tube (68) which carries the steam from the steam fixed chamber (57). The input of the tube (68) is sealed by a mechanical seal (71).
