Description

BACKGROUND

Technical Field

The present disclosure is directed to a steam press for ironing clothes and, more particularly, to a steam press system and methods of controlling steam generation and recycling steam therein.

Description of Related Art

The “background” description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description which may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present invention.

Conventional steam ironing machines include ironing boards defined by multiple holes to deliver steam. Steam may be generated by a steam generator that works in conjunction with a water pump for feeding a boiler of the steam generator, and a pipe network to supply water and generated steam. In an ironing operation, the steam is generated continuously in the boiler and delivered to the ironing boards where heat associated with the steam aids removal of wrinkles and provides a professional press appearance to garments. Steam ironing machines may also include a suction pump controlled by a foot pedal or the like, to regulate the vacuum pressure required to remove the steam from the garments and the boards. Thereafter, residual steam is rejected to a drain by the suction pump. Typically, the steam generators consume power in a range from 8 kW to 18 kW and the daily water consumption of a medium size commercial steam ironing machine ranges from 200 to 500 liters. Considering that a plurality of such commercial steam ironing machines operate in laundries and hotels worldwide, a large amount of electricity and water is consumed for steam generation during operation thereof.

CN206204654U describes a clothes steam ironing equipment with steam recycling function which includes a heat absorbing box with a radiating pipe connected to a waste steam inlet pipe that heats cold water, and reclaimed steam enters a heat sink pipe in the heat absorption box, surrounded by a heat sink. However, this publication does not describe ironing plates or a control system which uses the readings from pressure sensor(s) and/or temperature sensor(s) to render the steam and heat generation and reclamation process efficient.

CN109629214A describes a pressing/ironing box having a pressing plate which moves over the clothing on a pressing table; a hood over the pressing table collects waste heat that is used to preheat cold water entering a preheating box; a heating box that generates the steam; and a computer that controls the operation of switches, a water pump, an air pump, and valves. This publication fails to describe aspects of steam reclamation and the use of sensor(s) to render the process efficient.

CN207958816U describes an industrial iron capable of recycling steam, including a steam generator and a steam recovery device which supplies preheated water to the steam generator; a tube through the steam recovery device which exchanges heat with the recycled steam to warm the water. CN211256302U describes a steam reclaiming iron in which the steam is recycled to preheat cold incoming water before the cold water is supplied to a heater. However, both CN207958816U and CN211256302U do not mention a computer control, or details of a heat exchanger, pressure valves, temperature sensors and controls.

As such, each of the aforementioned references suffers from one or more drawbacks hindering their adoption. Accordingly, it is one object of the present disclosure to provide system and methods of controlling steam generation and recycling the steam and heat contained within and used during pressing operations by using controlled procedures to render the steam and heat generation process and steam reclamation process efficient.

DETAILED DESCRIPTION

In the drawings, like reference numerals designate identical or corresponding parts throughout the several views. Further, as used herein, the words “a,” “an” and the like generally carry a meaning of “one or more,” unless stated otherwise.

Furthermore, the terms “approximately,” “approximate,” “about,” and similar terms generally refer to ranges that include the identified value within a margin of 20%, 10%, or preferably 5%, and any values therebetween.

Aspects of the present disclosure are directed to a steam press system and methods of controlling steam generation and recycling steam therein. The steam press system includes a steam generator to deliver the steam to steam plates for ironing and steaming clothes, a suction pump to take out moisture and rejected steam from the steam plates, and a heat exchanger to exchange heat between the rejected steam and incoming fresh water to be passed to the steam generator. Water level control and pressure control are integrated into the steam generator. The steam press system allows recovery of heat from the rejected steam and uses the steam to heat the incoming fresh water before it enters the steam generator. As such, the steam generator requires minimal energy to convert the pre-heated water into steam. Further, the rejected steam and heat of the steam is captured and condensed in the heat exchanger, and subsequently recycled by the steam press system. Thus, the steam press system may reduce energy consumption and achieve a significant reduction in use of water.

Referring to FIG. 1, a perspective view of a steam press system 100 is illustrated, according to an embodiment of the present disclosure. The steam press system 100 includes an outer case 102. The outer case 102 is embodied as a cabinet having a predetermined volume to house various components of the steam press system 100. Although in the illustrated example, the outer case 102 is shown as a cuboidal structure, it will be appreciated that, in other examples, the outer case 102 may have any other suitable shape (such as cylindrical). In some examples, the outer case 102 may be made of suitable materials to withstand high temperatures, such as, but not limited to, a high performance polymer including polytetrafluoroethylene (PTFE), austenitic stainless steels, and the like. In some examples, the outer case 102 may include an insulation layer to prevent loss of heat therefrom and to prevent accidental heat shock to a user operating the steam press system 100.

The steam press system 100 includes a first steam plate 110 and a second steam plate 120. The first steam plate 110 and the second steam plate 120 are coupled to the outer case 102. Specifically, the first steam plate 110 and the second steam plate 120 are coupled to protrusions 104a, 104b of the outer case 102. As shown, the protrusions 104a, 104b extend in a vertical direction from a top portion of the outer case 102. The steam press system 100 also includes two struts, such as a first strut 106 and a second strut 108, each extending from the first steam plate 110. In some embodiments, the second steam plate 120 may be coupled to the outer case 102 with help of similar struts (not shown in FIG. 1). Preferably, the second steam plate 120 is arranged vertically below the first steam plate 110 and the second steam plate 120 is stationary. In one embodiment, the first strut 106 and the second strut 108 may be pivotally coupled to the respective protrusions 104a, 104b, to allow angular movement of the first steam plate 110 with respect to the second steam plate 120. In such arrangement, each of the first strut 106 and the second strut 108 may be coupled to the first steam plate 110 via a ball joint (not shown) to allow flexible movement on the first steam plate 110 by the user. The ball joint may allow the first steam plate 110 to be held parallel with respect to the second steam plate 120 when the first steam plate 110 is moved in an arcuate direction with respect to the second steam plate 120. Further, each of the protrusions 104a, 104b may include a stopper (not shown) to restrict such angular movement of the first strut 106 and the second strut 108 beyond a predetermined angle. In some embodiments, each of the protrusions 104a, 104b may include a mechanism (not shown) to retain the first steam plate 110 at a desired angular position while the steam press system 100 is being used by the user. Such mechanism may add to the convenience of the user while the user replaces a garment to be ironed or changes a side of the garment to be ironed. Additionally, such mechanism may add to the comfort of a taller or a shorter user by allowing a higher or lower positioning of the upper steam plate.

In another embodiment, the first steam plate 110 may be connected to the protrusions 104a, 104b by, for example, a prismatic joint, such as a slider or the like, to allow vertical movement (downwards and upwards) of the first steam plate 110 in a direction towards or away with respect to the second steam plate 120.

Each of the first steam plate 110 and the second steam plate 120 includes an inlet and an outlet to, respectively, receive and evacuate steam therefrom. In particular, the first steam plate 110 includes a first steam plate inlet 110a and a first steam plate outlet 110b, and the second steam plate 120 includes a second steam plate inlet 120a (as shown in FIG. 2, not visible in FIG. 1) and a second steam plate outlet 120b (generally labelled in FIG. 1 and more clearly shown in FIG. 2). The first steam plate 110 is configured to receive steam at the first steam plate inlet 110a and vent the steam through the first steam plate outlet 110b. Similarly, the second steam plate 120 is configured to receive steam at the second steam plate inlet 120a and vent the steam through the second steam plate outlet 120b.

Further, the first steam plate 110 includes a first inner surface 112 (as shown in FIGS. 8A and 8B, not visible in FIG. 1) and the second steam plate 120 includes a second inner surface 122. The first inner surface 112 of the first steam plate 110 faces the second inner surface 122 of the second steam plate 120. In an example, the first inner surface 112 and the second inner surface 122 are made from iron. In another example, the first inner surface 112 and the second inner surface 122 are made from one of anodized aluminum, titanium alloy, stainless steel, porcelain, satin aluminum, polished aluminum, ceramic, and titanium. These materials exhibit excellent heat conducting capability, aid in the even distribution of heat, prevent or eliminate static, provide a smooth surface, prevent the garment from sticking to the surface, and require minimum maintenance. In the steam press system 100, each of the first inner surface 112 and the second inner surface 122 includes a pattern of holes (such as an array) distributed evenly. The first inner surface 112 of the first steam plate 110 define holes 114 (as shown in FIGS. 8A and 8B, not visible in FIG. 1) and the second inner surface 122 of the second steam plate 120 define holes 124. Each of the holes 114 in the first steam plate 110 and each of the holes 124 in the second steam plate 120 are configured to supply the steam, such that the garment placed between the first steam plate 110 and the second steam plate 120 may absorb the supplied steam from both sides, which in turn may aid in the ironing of the garment.

The steam press system 100 also includes a first foot pedal 130 and a second foot pedal located at a bottom portion of the outer case 102, at a front side thereof. The first foot pedal 130 and the second foot pedal 132 are operated by the foot of the user. In some embodiments, the first foot pedal 130 and the second foot pedal 132 may be used to regulate the flow of steam. Further, the steam press system 100 may include a temperature control switch 134 and a pressure control switch 136 provided on the outer case 102. As shown, the temperature control switch 134 and the pressure control switch 136 may be located on the front side of the outer case 102 so as to be accessible to the user. In an embodiment, the temperature control switch 134 and the pressure control switch 136 may be actuatable by a knee of the user. The temperature control switch 134 and the pressure control switch 136 may be configured to regulate the temperature and the pressure of the steam. In some embodiments, a display screen (not shown) may be provided on the outer case 102 to display values of the temperature and the pressure being set by the user via the temperature control switch 134 and the pressure control switch 136, respectively. In some embodiments, the display screen may be a touchscreen configured to allow the user to select a type of material of the garment, such as cotton, silk, etc., and the value of the temperature and the pressure of the steam may be set automatically based on the type of the material.

FIG. 2 illustrates a schematic diagram of the steam press system 100 showing a block diagram of components housed within the outer case 102. Referring to FIG. 1 and FIG. 2 in combination, the steam press system 100 includes a first piping arrangement 140 connected to the first steam plate outlet 110b and the second steam plate outlet 120b. The steam press system 100 also includes a second piping arrangement 142 connected to the first steam plate inlet 110a and the second steam plate inlet 120a. As illustrated in FIG. 2, the steam press system 100 further includes a first pump 210 connected to the first piping arrangement 140, a heat exchanger 220, a second pump 230, a third pump 240, a storage tank 250, a fourth pump 260 and a steam generator 270 connected to the second piping arrangement 142. The first pump 210 has a first pump inlet 210a and a first pump outlet 210b; the heat exchanger 220 has a first heat exchanger inlet port 220a, a second heat exchanger inlet port 220b and a heat exchanger outlet port 220c; the second pump 230 has a second pump inlet 230a and a second pump outlet 230b; the third pump 240 has a third pump inlet 240a and a third pump outlet 240b; the storage tank 250 has a storage tank inlet 250a and a storage tank outlet 250b; the fourth pump 260 has a fourth pump inlet 260a and a fourth pump outlet 260b; and the steam generator 270 has a steam generator inlet 270a and a steam generator outlet 270b. The first pump inlet 210a is connected to the first steam plate outlet 110b and the second steam plate outlet 120b via the first piping arrangement 140, and the first pump outlet 210b is connected to the first heat exchanger inlet port 220a. Further, the second pump inlet 230a is connected to a freshwater source, such as a reservoir (not shown) or cold water pipe (not shown), and the second pump outlet 230b is connected to the second heat exchanger inlet port 220b. Further, the third pump inlet 240a is connected to the heat exchanger outlet port 220c and the third pump outlet 240b is connected to the storage tank inlet 250a. Further, the fourth pump inlet 260a is connected to the storage tank outlet 250b and the fourth pump outlet 260b is connected to the steam generator inlet 270a. Additionally, the steam generator outlet 270b is connected to the first steam plate inlet 110a and the second steam plate inlet 120a via the second piping arrangement 142.

The first pump 210, the heat exchanger 220, the second pump 230, the third pump 240, the storage tank 250, the fourth pump 260 and the steam generator 270 are enclosed within the outer case 102. However, in other examples, one or more of these components may be located outside of the outer case 102 and suitably connected to remaining component(s) housed inside the outer case 102. It may also be understood (and as may be seen from FIG. 1) that the first piping arrangement 140 and the second piping arrangement 142 may be located partially outside the outer case 102 to be connected to the steam plates 110, 120, and may be located partially inside the outer case 102 to be connected to the first pump 210 and the steam generator 270, respectively. The first piping arrangement 140 and the second piping arrangement 142 may extend from openings defined in the outer case 102, or in the protrusions 104a, 104b of the outer case 102. In the illustrated embodiment, the openings are defined on lateral sides of the protrusions 104a, 104b. However, alternatively, the openings may be formed at front sides of the protrusions 104a, 104b of the outer case 102, facing the first steam plate 110 and the second steam plate 120. Each of the first piping arrangement 140 and the second piping arrangement 142 is configured to allow flow of steam therethrough and hence may be at high temperatures. In some embodiments, portions of the first piping arrangement 140 and the second piping arrangement 142 exposed to the outside of the outer case 102 may be insulated (i.e., provided with an insulating layer) to prevent burns due to accidental touching by the user while operating the steam press system 100.

In some embodiments, the various components of the steam press system 100 may work in conjunction with one another to generate and recycle the steam therein. In the steam press system 100, the first pump 210 is configured to draw the steam from the first piping arrangement 140. The first pump 210 is further configured to receive the rejected steam at the first pump inlet 210a, increase pressure of the steam, and expel the steam via the first pump outlet 210b, so that the pressurized steam is directed into the heat exchanger 220 via the first heat exchanger inlet port 220a. The second pump 230 is configured to pump fresh water at a first temperature from the freshwater source into the heat exchanger 220 via the second heat exchanger inlet port 220b. The first temperature may be in a range of about 5 degrees Celsius to about 35 degrees Celsius. The heat exchanger 220 is configured to condense the received pressurized steam by heating the fresh water to a second temperature greater than the first temperature. In an example, the second temperature is in a range of about 85 degrees Celsius to about 100 degrees Celsius.

The steam press system 100 may include a water level sensor 222 deposed within the heat exchanger 220. In a non-limiting example, the water level sensor 222 is an ultrasonic water level sensor, available from, for example, Water Level Control, Arizona, U.S. The water level sensor 222 is configured to detect a level of the water inside the heat exchanger 220 and generate a water level reading. Further, the heat exchanger outlet port 220c is configured to expel the heated water. In an example, the heated water is expelled based on the water level reading, i.e., when the water level is above a predefined water level threshold. Thereafter, the third pump 240 is configured to transfer the heated water from the heat exchanger outlet port 220c to the storage tank inlet 250a, to be stored in the storage tank 250. The storage tank 250 is configured to store the heated water at the second temperature. For this purpose, the storage tank 250 may be provided with an insulation layer. In some examples, the steam press system 100 also includes a check valve 252 located between the third pump 240 and the storage tank inlet 250a. The check valve 252 is configured to prevent backflow of the heated water from the storage tank 250. The fourth pump 260 is configured to pump the stored heated water from the storage tank 250 via the storage tank outlet 250b to the steam generator 270 via the steam generator inlet 270a.

The steam generator 270 is configured to receive the heated water at the second temperature from the fourth pump 260 and boil the heated water to generate steam at a third temperature. In some embodiments, the steam press system 100 may include a steam generator heating circuit 272 located within the steam generator 270. The steam generator heating circuit 272 is configured to control generation of heat within the steam generator 270, based on, for example, an amount of heated water to be converted to the steam at the third temperature. In an example, the steam generator heating circuit 272 includes at least one steam generator heating element 274, a power switch 275, and a temperature control circuit 276. The steam generator heating element 274 may be configured to generate the heat required to boil the water. In an example, the steam generator heating element 274 is a resistive heating element as known in the art (“the steam generator heating element” and “resistive heating element” are interchangeably used hereinafter). The power switch 275 may be configured to control switching ON and OFF the steam generator 270 and may be accessible from the outside of the housing by a connected button or switch. Further, the temperature control circuit 276 may be configured to control the steam generator heating element 274 to regulate steam generation with its temperature up to the third temperature. In an example, the third temperature may be in a range of 130 degrees Celsius to 180 degrees Celsius. The steam generator 270 is further configured to deliver the steam to the first steam plate inlet 110a and the second steam plate inlet 120a through the second piping arrangement 142. In some embodiments, the steam press system 100 may include a controllable pressure valve 278 connected between the steam generator outlet 270b, and the first steam plate inlet 110a and the second steam plate inlet 120a to ensure a regulated pressure of the steam is supplied to the first steam plate 110 and the second steam plate 120. The regulated pressure may be in the range of five bars to six bars. Further, the first steam plate 110 and the second steam plate 120 may be configured to further heat (superheat) the received steam from the third temperature to a fourth temperature greater than the third temperature. In an example, the fourth temperature may be in a range of 180 degrees Celsius to 190 degrees Celsius.

In some embodiments, the first foot pedal 130 is configured to release steam from the steam generator 270. That is, the first foot pedal 130 is configured to control the flow of steam from the steam generator 270 into the first steam plate inlet 110a and the second steam plate inlet 120a. For this purpose, as shown in FIG. 2, the first foot pedal 130 may be mechanically or electronically connected to the steam generator 270, for example, to control opening and closing of the steam generator outlet 270b or a valve connected to the steam generator outlet 270b. Further, as discussed, the first pump 210 is configured to draw the steam from the first steam plate outlet 110b and the second steam plate outlet 120b, via the first piping arrangement 140, and expel the steam at the first pump outlet 210b. In some embodiments, the second foot pedal 132 is configured to operate the first pump 210 to evacuate the steam from the first steam plate outlet 110b and the second steam plate outlet 120b. In particular, the second foot pedal 132 is configured to open a valve to eject the steam through the holes 114 and 124 in the first inner surface 112 and the second inner surface 122, respectively, and thereafter the first pump 210 is operated to evacuate the steam from the first steam plate outlet 110b and the second steam plate outlet 120b. For this purpose, as shown in FIG. 2, the second foot pedal 132 may be mechanically or electronically connected to the first pump 210 to regulate suction power of the first pump 210, and/or to control opening and closing of the first pump inlet 210a and the first pump outlet 210b.

The fourth temperature sensor 296 may be configured to measure and provide readings for the fourth temperature of the steam in the first steam plate 110 and the second steam plate 120.

In some embodiments, the steam press system 100 further includes a controller 400 configured to control generation and recycling of the steam. FIG. 4 illustrates an exemplary block diagram showing connections between the controller 400 and various components of the steam press system 100. As shown, the controller 400 is connected to:

• • (a) the first temperature sensor 284, the second temperature sensor 294, the third temperature sensor 288, the fourth temperature sensor 296 to receive respective readings for the first, second, third, and fourth temperatures;
  • (b) the first pressure sensor 280, the second pressure sensor 282, the third pressure sensor 286, the fourth pressure sensor 290, the fifth pressure sensor 292 to receive respective readings of the first, second, third, fourth and fifth pressures, wherein the first, second, third, fourth and fifth pressures are within the range of five bars to six bars;
  • (c) the controllable pressure valve 278 to regulate flow of the steam by controlling the pressure of the steam (i.e., the third pressure) being supplied to the first steam plate 110 and the second steam plate 120; and
  • (d) the steam generator heating circuit 272 to control steam generation.

In the steam generator heating circuit 272, the controller 400 is connected to: (a) the steam generator heating element 274 to regulate supply of power thereto thereby controlling the temperature and pressure within the steam generator 270, and (b) the power switch 275 and the temperature control circuit 276 to control heating of the water in the steam generator 270 and thus generation of the steam. The controller 400 may further be connected to the water level sensor 222 to receive the corresponding water level reading therefrom. The controller 400 is configured to adjust a power supplied to the first pump 210 based on the water level reading to supply a sufficient amount of the rejected heat to bring the temperature of water in the heat exchanger 220 to the required second temperature. In some embodiments, the controller 400 may also be provided with a first set of temperature setpoint values which may define standard operational values for the first, second, third, and fourth temperatures, and a second set of pressure setpoint values which may define standard operational values for the first, second, third, fourth and fifth pressures. The said first set of temperature setpoint values and the second set of pressure setpoint values may be stored in a memory (such as a memory 1102 in FIG. 11) associated with the controller 400. Further, the controller 400 is connected to the temperature control switch 134 and the pressure control switch 136. The temperature control switch 134 and the pressure control switch 136 may be operated to provide instructions to change the first set of temperature setpoint values and the second set of pressure setpoint values, respectively, stored in the controller 400, for example, for particular ironing operation based on the requirement.

In some embodiments, the controller 400 includes a non-transitory computer readable medium having instructions stored therein that, when executed by one or more processors, cause the one or more processors to perform corresponding functions. In some embodiments, the controller 400 may be implemented in hardware, firmware or software, or some combination of at least two of the same. It should be noted that the functionality associated with the controller 400 may be centralized or distributed, whether locally or remotely. The controller 400 may be a multi-core processor, a single core processor, or a combination of one or more multi-core processors and one or more single core processors. For example, the one or more processors may be embodied as one or more of various processing devices, such as a coprocessor, a microprocessor, a digital signal processor (DSP), a processing circuitry with or without an accompanying DSP, or various other processing devices including integrated circuits such as, for example, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a microcontroller unit (MCU), a hardware accelerator, a special-purpose computer chip, or the like. Further, the memory associated with the controller 400 may include one or more non-transitory computer-readable storage media that can be read or accessed by other components in the device. The memory may be any computer-readable storage media, including volatile and/or non-volatile storage components, such as optical, magnetic, organic, or other memory or disc storage, which can be integrated in whole or in part with the device. In some examples, the memory may be implemented using a single physical device (e.g., optical, magnetic, organic, or other memory or disc storage unit), while in other embodiments, the memory may be implemented using two or more physical devices without any limitations.

In some embodiments, the controller 400 is configured to monitor the first, second, third, and fourth temperatures. The controller 400 is further configured to monitor the first, second, third, fourth and fifth pressures. The controller 400 is also configured to compare the first, second, third, and fourth temperatures to the first set of temperature setpoint values. The controller 400 is further configured to compare the first, second, third, fourth and fifth pressures to the second set of pressure setpoint values. As such, the controller 400 may be configured to generate control signals to adjust the first pump 210, the second pump 230, the third pump 240, the fourth pump 260, the controllable pressure valve 278, and a power supplied to the steam generator heating circuit 272 to the first set of temperature setpoint values and the second set of pressure setpoint values. In particular, the controller 400 is configured to generate control signals to adjust the first pump 210, the second pump 230, the third pump 240, the fourth pump 260, the controllable pressure valve 278, and the power supplied to the steam generator heating circuit 272 to cause the first, second, third, and fourth temperatures to match the first set of temperature setpoint values and the first, second, third, fourth and fifth pressures to match the second set of pressure setpoint values. That is, the controller 400 may control the components to regulate the first, second, third, and fourth temperatures, and the first, second, third, fourth and fifth pressures based on the corresponding setpoint values as preset by the user. For instance, if the user wishes to use steam with high temperature and high pressure to iron heavy clothes, then the user may use the temperature control switch 134 to increase the setpoint value for the third temperature (i.e., the temperature at which the steam is supplied to the first steam plate 110 and the second steam plate 120) and the pressure control switch 136 to increase the setpoint value for the third pressure (i.e., the pressure at which the steam is supplied to the first steam plate 110 and the second steam plate 120). It may be appreciated that the setpoint values for other temperatures and pressures may automatically be adjusted based on adjustment of, for example, the third temperature and/or the third pressure based on operating parameters of the steam press system 100. As would be contemplated by a person skilled in the art, the controller 400 may utilize predefined or preprogrammed value maps for this purpose, not described herein for brevity of the present disclosure.

Referring to FIG. 5, a perspective view of the heat exchanger 220 is illustrated. Further referring to FIG. 6A, a cross-sectional view of the heat exchanger 220 of FIG. 5 is illustrated. As shown in FIG. 5 and FIG. 6A, the heat exchanger 220 includes a housing 502 embodied as a cylindrical insulated structure. That is, the housing 502 may include an insulation layer (not shown) thereon. The insulation layer may prevent loss of heat from the interior of the housing 502 where the rejected steam at high temperature is received to mix with fresh water to generate heated water. As seen in FIG. 5, the housing 502 provides the first heat exchanger inlet port 220a, the second heat exchanger inlet port 220b and the heat exchanger outlet port 220c.

In some embodiments, the heat exchanger 220 is a direct contact heat exchanger to achieve rapid condensation and maximum heat transfer. The heat exchanger 220 includes a plurality of supports 504, ends of which are attached to interior of the housing 502. Each support 504 has a circular opening 506 (see FIG. 6A) at a central location. In an example, each circular opening 506 includes a rotatable bearing (not shown). Further, as shown, the heat exchanger 220 includes a swirl generator 510 inserted through the first heat exchanger inlet port 220a and through the rotatable bearings. In the heat exchanger 220, the swirl generator 510 is connected to the first pump outlet 210b. The swirl generator 510 is in the form of a pipe and is configured to extend coaxially with a central axis of the cylindrical insulated housing 502. Furthermore, as shown, the heat exchanger 220 includes a plurality of pipe arms 512 located on the swirl generator 510. In the example illustration of FIGS. 5 and 6A, four pipe arms 512 are shown, arranged in two pairs disposed in two planes towards bottom of the housing 502. Each pipe arm 512 ends in a 90 degree bend (as represented by reference numeral 514). Although the bends 514 are disposed at 90 degrees and in same plane with respect to the corresponding pipe arm 512, in other embodiments, the bends 514 may be disposed at angles other than 90 degrees and in a different plane with respect to the corresponding pipe arm 512. In the heat exchanger 220, each pipe arm 512 is configured receive steam from the swirl generator 510 and expel steam into the freshwater present in the housing 502 through the respective bend 514. The bends 514 act as nozzles to expel steam into the fresh water at high pressure. This expelling of the steam from oppositely directed bends 514 may generate opposing force, which rotates each pipe arm 512 around the central axis (due to support of the swirl generator 510 by the rotatable bearings), such that a swirling flow is generated in the freshwater to cause proper mixing of the steam into the fresh water and thus faster heating of water in the heat exchanger 220. In some embodiments, a size (area) of opening of the bends (nozzles) 514 may be varied to regulate pressure at which the steam is expelled into the fresh water, and thereby control swirling flow generated in the heat exchanger 220. Referring to FIG. 6B, a cross-sectional view of the heat exchanger 220 is illustrated according to another embodiment. The swirl generator 510 may include additional pipe arms 602, specifically two additional pipe arms 602 with corresponding bends 604. In an embodiment, the pipe arms 602 and the pipe arms 512 may be located equidistant from an adjacent pipe arm along the swirl generator 510. Such additional pipe arms 602 may help with uniform expelling of the steam inside the housing 502 of the heat exchanger 220 and may further increase degree of swirl in the freshwater, thereby resulting in even mixing of the steam with the freshwater. Thus, faster heating of water in the heat exchanger 220 may be achieved as compared to the embodiment illustrated in FIG. 6A.

FIG. 6C illustrates an alternative embodiment of the heat exchanger 220. In FIG. 6C, a ring 618 is employed to mix the recycled steam 622 generated by the steam press of the previous embodiments. A manifold having a first pipe branch 614 and a second pipe branch 610 splits the recycled steam 622 into two streams. The steam from first pipe branch 614 enters the housing through a first steam port 616 and the steam from the second pipe branch 610 enters the housing through a second steam port 612. Each steam port includes a seal to prevent water loss from the housing 502. The first pipe branch 614 and the second pipe branch 610 are fluidly connected to each other and to a ring 618, which has steam holes 620. Additionally, a steam hole 620 (see FIG. 6D) is located in the pipe at the center of the ring 618. A water pipe 606 having an end in the water, W, inside the housing, draws the heated water (through action of a pump, not shown) out of the housing, where it is delivered to the steam generator 270. Alternatively, the heated water may be delivered to the storage tank 250. The pump may be essentially the same as the pump 240 or the pump 260 shown in FIG. 2. The heated water pipe 606 exits the housing 502 through a sealed exit port 608. The heat exchanger 220 is supplied with fresh water 628, which is pumped by fresh water pump 626 through fresh water pipe 624 into the bottom of the housing 220. In operation, steam from the steam manifold is propelled into the water at the bottom of the housing through the steam holes. The pressure of the steam entering the water in the housing 502 may be within the range of five bars to six bars, and the temperature of the fresh water may initially be in the range of about 5 degrees Celsius to about 35 degrees Celsius. The heat from the steam heats the fresh water to a second temperature in a range of about 85 degrees Celsius to about 100 degrees Celsius.

FIG. 6D illustrates a manner in which the ring 618 may be supported within the housing 502. An outer ring 638 may be connected to the inner wall of the housing by mounts 632 and held in place by collars 634. Spokes 630 radiating from the outer ring 638 are connected to the ring 618 by clamps (not shown). The steam holes 620 are shown in the ring 618 and in the center of the steam manifold. The collars 634 may be rubber or rubberized metal to prevent vibration noise. The mounts 632 may hold the ring 618 at a height in the range of 2 cm to 10 cm above the bottom of the housing 520.

FIG. 6E shows a side view of the heat exchanger of FIG. 6C, in which a fresh water inlet port 668 at the bottom 656 of housing 502 is shown more clearly. The steam holes 620 in the ring and in the center of the steam pipe are shown. The sealed exit port 608 is shown at the top 650 of the heat exchanger.

FIG. 6F illustrates another embodiment of the heat exchanger 220 having two steam rings. The embodiment of FIG. 6F is essentially the same as the embodiment of FIG. 6C, but with the addition of a second steam ring. A top cross-section is shown in which ring 618 is an inner ring and ring 664 is an outer ring. Ring 618 has steam holes 620 and ring 664 has steam holes 666. The manifold labelled as first pipe branch 614 and second pipe branch 610 also has a steam hole 620. The manifold is fluidly connected to the ring 618 and the ring 664. The ring 618 and the ring 664 are concentric and at the same height from the bottom of the housing, which height may be in the range of 2 cm to 10 cm above the bottom of the housing 520.

In FIG. 6C-FIG. 6F, the steam holes 620 and 666 may be 2 mm to 6 mm in diameter. In a particular embodiment of the ring 618 of FIG. 6C, the steam holes 620 may be 4 mm in diameter. In a particular embodiment of the ring 618 of FIG. 6C, the steam holes 620 may be 2 mm in diameter. In another particular embodiment of FIG. 6F, the ring 618 may have steam holes of 2 mm in diameter and the ring 624 may have steam holes 666 may have a diameter of 4 mm. In another embodiment of FIG. 6F, the ring 618 may have steam holes of 4 mm in diameter and the ring 624 may have steam holes 666 may have a diameter of 2 mm. In another embodiment of FIG. 6F, the ring 618 may have steam holes of 4 mm in diameter and the ring 624 may have steam holes 666 may have a diameter of 4 mm. In another embodiment of FIG. 6F, the ring 618 may have steam holes of 6 mm in diameter and the ring 624 may have steam holes 666 may have a diameter of 4 mm. In another embodiment of FIG. 6F, the ring 618 may have steam holes of 4 mm in diameter and the ring 624 may have steam holes 666 may have a diameter of 6 mm. In another embodiment of FIG. 6F, the diameters of the steam holes 620 and 666 may be the same. In another embodiment of FIG. 6F, the diameters of the steam holes 620 and 666 may be different, in the range of 2 mm to 6 mm.

In an embodiment, the height of the heat exchanger 200 is 100 cm. However, the height of the heat exchanger 220 is not limiting and may be greater or less than 100 cm, depending on the needs of specific applications.

Any of the embodiments shown in FIG. 6C, and FIG. 6E-FIG. 6F may include the support structure shown in FIG. 6D.

FIG. 7 illustrates sectioned steam plates of the steam press system of the steam press system 100. FIGS. 8A-8B illustrate cross-sectional views of steam plates 110, 120 of the steam press system 100 according to two different embodiments. Together referring to FIG. 7, FIG. 8A and FIG. 8B, as illustrated, the first steam plate 110 includes a first steam plate housing 710 having the first inner surface 112, a top cover 712, and a first middle region 714. The first middle region 714 is defined between the first inner surface 112 and the top cover 712. The top cover 712 includes extensions 716 around its circumference which protrude past the first inner surface 112. Further, the second steam plate 120 includes a second steam plate housing 720 having the second inner surface 122, a bottom cover 722 and a second middle region 724. The second middle region 724 is defined between the second inner surface 122 and the bottom cover 722. Also, the second inner surface 122 has a groove 726 around its circumference. The groove 726 is configured to receive the extensions 716 of the first steam plate housing 710 when the first steam plate 110 is pressed against the second steam plate 120, thereby achieving a leak-proof engagement of the first steam plate 110 with the second steam plate 120 in the steam press system 100. The outer surfaces of the steam plates may include insulation to prevent burns and may have handles or other hardware to allow the user to raise and lower the upper steam plate without being burned.

In one embodiment, as illustrated in FIG. 8A, the steam press system 100 may include an electromagnetic coil 810 located within the first middle region 714. Also, an alternating current circuit 812 (schematically shown) is coupled to the electromagnetic coil 810, such that the electromagnetic coil 810 generates an alternating magnetic induction field when the alternating current is applied by the alternating current circuit 812. Further, the steam press system 100 may include a permanent magnet 814 located within the second middle region 724. Eddy currents are generated in the permanent magnet 814 due to the alternating magnetic induction field. The eddy currents heat the steam in both the first steam plate 110 and the second steam plate 120 from the third temperature to the fourth temperature greater than the third temperature. That is, the steam press system 100 may provide an additional heating arrangement incorporated in the first steam plate 110 and the second steam plate 120, implementing the electromagnetic coil 810, the alternating current circuit 812 and the permanent magnet 814 to further heat (superheat) the steam to the fourth temperature, if required.

In another embodiment, as illustrated in FIG. 8B, the steam press system 100 may include a first resistive heater 820 located within the first middle region 714 and a first resistive heating circuit 822 (schematically shown) connected to the first resistive heater 820. The first resistive heating circuit 822 is configured to increase the third temperature of the steam to a temperature setpoint value. Further, the steam press system 100 may include a second resistive heater 824 located within the second middle region 724 and a second resistive heating circuit 826 (schematically shown) connected to the second resistive heater 824.

The resistive heating element 274 may be the part of the steam generator heating circuit 272 to control heat being supplied in the steam generator 270, as required to boil the heated water to generate the steam at the third temperature. The power switch 275 may be used to control switching ON and OFF the steam generator 270. Further, the temperature control circuit 276 may be used to regulate the resistive heating element 274 to heat the water generating steam with up to the defined third temperature.

At step 914, the method 900 includes delivering, by the controllable pressure valve 278, the steam at the third temperature to the first steam plate inlet 110a and a second steam plate inlet 120a. That is, the controllable pressure valve 278 is used to regulate flow of the steam by controlling the pressure of the steam (from the third pressure) being supplied to the first steam plate 110 (through the corresponding first steam plate 110) and the second steam plate 120 (through the corresponding second steam plate inlet 120a).

Although not illustrated through steps in FIG. 9, the method 900 further includes pressing the first foot pedal 130 to actuate the controllable pressure valve 278 to deliver steam to the first steam plate inlet 110a and the second steam plate inlet 120a. The method 900 further includes heating, by resistive heating or inductive heating (as described in reference to FIGS. 8A and 8B), the steam within the first steam plate 110 and the second steam plate 120 to the fourth temperature higher than the third temperature. The method 900 further includes pressing the second foot pedal 132 to actuate the first pump 210 to evacuate the steam from the first steam plate outlet 110b and the second steam plate outlet 120b. The method 900 further includes pumping, by the first pump 210, the steam into the first heat exchanger inlet port 220a to recycle the steam.

The controller 400 includes a non-transitory computer readable medium having instructions stored therein that, when executed by one or more processors, cause the one or more processors to perform the following steps (hereinafter described to be performed by the controller 400 itself). The controller 400 monitors the water level reading in the heat exchanger 220. The controller 400 compares the water level to a water level threshold. The controller 400 monitors the first, second, third, and fourth temperatures. The controller 400 monitors the first, second, third, fourth and fifth pressures.

In particular, the controller 400 generates control signals to adjust the first pump 210, the second pump 230, the third pump 240, the fourth pump 260, the controllable pressure valve 278, and the power supplied to the steam generator heating circuit 272 to cause the first, second, third, and fourth temperatures to match the first set of temperature setpoint values and the first, second, third, fourth and fifth pressures to match the second set of pressure setpoint values.

The steam press system 100 implements the steam generator 270, with the resistive heating element 274 inserted into the steam generator 270, for boiling the water to deliver the steam to ironing station including the first steam plate 110 and the second steam plate 120. Further, the first pump 210 acts as a suction source to take out moisture and rejected steam from ironed clothes placed between the first steam plate 110 and the second steam plate 120. The heat exchanger 220 is used to exchange heat between the waste steam and the incoming fresh water to heat up the water before being passed to the steam generator 270. In the heat exchanger 220, the heat transfer takes place between the fresh water and the rejected steam, leading to increased water temperature and condensation of the steam. The free-rotating, direct-contact swirl generator 510 is designed to condense steam and heat fresh water efficiently in the heat exchanger 220. Thus, the steam press system 100 helps to recover the heat energy in the rejected steam to heat the fresh water before entering the steam generator 270, so that the pre-heated water in the steam generator 270 may require less energy to produce steam. Furthermore, the rejected steam is captured and recycled in the steam press system 100 which, in addition to lowering the energy consumption needed to heat the water, may lead to a significant reduction in water use. The steam plates 110, 120 with complementary design to include the extensions 716 and the groove 726 may help to prevent the escape of the steam to the surrounding environment, which improves the working environment of the ironing shop and reduces the required power for the air-conditioning system inside the shops. Further, water level control, temperature control and pressure control is integrated into the steam press system 100 for efficient steam generation and reclamation. Therefore, the steam press system 100 advances the performance of the prior art steam generators in providing heat and mass recovery. Such a supplementary recovery system helps in utilizing the latent and sensible heat of the waste steam to increase the inlet temperature of the fresh water and hence reduce the power consumption of the steam generator 270 and may also help to reduce its size. Moreover, the steam press system 100 also reduces the water consumption by recirculating the condensed water again to the steam generator 270.
