This invention relates to a portable toilet device and it particularly relates to a portable toilet device that is available indoors. It, more particularly, relates to such that can certainly treat any excrement and the like with preventing the excrement from being spilt by providing within a body of the toilet device means for performing breaking-processing (stirring-processing) on the excrement and sending the broken excrement by compression, and a lid for open and closure, which prevents the excrement from being spilt and sending the excrement by compression efficiently.
A portable toilet device for an aged person who is necessary for any care or a handicapped person who has any difficulty of going to an existing toilet in his or her house has been developed (see, for example, Japanese Patent Application Publication No. 2004-308404).
This portable toilet device is designed to become a chair-type one in order to be able to be installed indoors so that bowel movement can be done with sitting on the chair. The portable toilet device is provided with a water-supplying hose that flushes rinse water into the toilet device, a drain hose for drain, which drains the excrement, and means for sending the excrement by compression.
By the way, although technology disclosed in the above-mentioned patent document has related to such the technology that the excrement can be drained from the toilet device by sending the excrement by compression, the excrement can be stagnant halfway through the drain hose when insufficient pressure for sending it by compression is supplied because the excrement is sent by compression as it is, so that any insanitation may occur.
Thus, this invention has solved such the conventional problem and provides a portable toilet device that is available indoors, which can certainly treat any excrement and the like with preventing the excrement from being spilt by particularly providing a lid for open and closure, which prevents the excrement from being spilt, with performing breaking-processing on the excrement, and by performing drain-processing on the broken excrement with sending it by compression.
In order to solve the above-mentioned problem, a portable toilet device according to this invention, which is claimed in claim 1, is characterized in that the device comprises a body of the device containing a water-supplying nozzle that flushes rinse water near an opening, and a drain opening that is communicated with a stagnant portion provided at a bottom thereof, means for breaking the excrement, which is installed at the stagnant portion of the body of the device, means for sending the broken excrement by compression, which is provided on an upside of the stagnant portion, and a lid for open and closure that closes the stagnant portion tightly, which is provided on an upside of the means for sending the broken excrement by compression.
The stagnant portion of the body of the device is provided with the means for breaking the excrement. It is conceivable that the means for breaking the excrement includes breaking/stirring type one and the other type one (such as breaking the excrement into fragments by a jet stream). Whatever happen, this means forces the excrement to be broken. The lid for open and closure is provided on an upside of the stagnant portion. It is conceivable that the lid for open and closure includes slidable type one and open/close type one. In course of the breaking process, the upside of the stagnant portion is closed by the lid for open and closure. Therefore, this prevents the excrement that is being broken into fragments from being spilt toward an opening side of the body of the toilet device.
The means for sending the broken excrement by compression is driven before or after the breaking process has been completed so that internal pressure in a closed space formed by the stagnant portion and the lid for open and closure can be increased. When the internal pressure reaches to a predetermined one, an electromagnetic valve is opened at a side of the drain opening. This enables the broken excrement to be sent toward a side of an existing toilet device, thereby preventing the excrement from being remained in a drain pipe connected to the existing toilet device.
Thus, according to this invention, the broken excrement and the like can be certainly drained with preventing the excrement from being spilt.
The following will describe preferred embodiments of the portable toilet device according to the invention more detailed with reference to drawings. The portable toilet device according to the invention is particularly suitable for a portable toilet equipped with a so-called shower toilet having any buttock-washing function. Any description on the shower toilet equipment will be omitted in the following description. In the embodiments, the portable toilet device is applied to a toilet of western type.
A stagnant portion 18 of trap water and the excrement is formed at a bottom of the body 20 of the toilet device. A drain portion 22 having a profiled configuration turned down at ends thereof, which is communicated with the stagnant portion 18, is provided and a drain hose 14 is connected to a drain opening 27. Thus, in this embodiment, a connection portion 26 is formed on a rear surface portion 20b of the body 20 of the toilet device and an electromagnetic valve 24 acting as on-off valve is mounted near the connection portion 26 inside the body 20 of the toilet device. It is conceivable that a configuration of the drain portion 22 communicated with the stagnant portion 18 includes configurations of P type, U type, bowl type and the like in addition to the shown configuration. All of these configurations cause similar effects.
The electromagnetic valve 24 is controlled so that it opens only when the trap water including the excrement in the stagnant portion 18 is drained out of the toilet device and it closes when the toilet device is not used. This is because the water is prevented from leaking. Simultaneously, this is also because the excrement can be efficiently drained based on a pressure by an air compressor 200, which will be described later.
A water-supplying nozzle 28 for rinse water is provided on a wall surface 18a, on a side of the drain portion, of the body 20 of the toilet device near an upper portion thereof. A connecting pipe 30 is arranged between a connection portion 34, which is provided on the rear surface portion 20b of the body, and the water-supplying nozzle 28 and an electromagnetic valve 32 is arranged near the connection portion 34. This is because this electromagnetic valve 32 may control any water supply from a water-supplying hose 12 connected to the connection portion 34. A leak-proof rubber tube 29 is inserted between the water-supplying nozzle 28 and the wall surface 18a, so that water is prevented from leaking to a side of a back-side space 20a of the body 20 of the toilet device.
Means 40 for breaking the excrement is installed at a bottom of the stagnant portion 18. The means 40 breaks into fragments the excrement and toilet paper, which are totally referred to as “the excrement”, stagnated in the stagnant portion 18, various kinds of the configurations of which are conceivable. Stirred (rotational) typed means, jet-stream typed means or the like is conceivable and in the jet-stream typed means, the excrement and the like is efficiently broken into fragments by means of cooperation with any breaking portion. Any liquid mixture broken by the means 40 for breaking the excrement is mixed with the trap water and drained.
The means 40 for breaking the excrement, which is shown in
In
A control unit 50 constituted of CPU and the like is arranged on the bottom plate 20c. Any driving of the above-mentioned electromagnetic valve 24 for drain, electromagnetic valve 32 for water supply, motor 42 and the like is controlled by the control unit 50 only during a predetermined period of time and at a predetermined timing. A power switch 52 for the control unit 50 is arranged on the rear surface portion 20b of the body, and an open/close detection switch 55 for the cover 23 is arranged on an upper surface of the body and under a lower surface of the cover 23.
Similarly, of the drain hose 14, an end 14a and the other end 14b are respectively provided with connection portions 62A, 62B, each of which has a check valve. In this moment, the end 14a is an end that is connected to a side of the portable toilet device 10, but the other end 14b is an end that is connected to a side of the drain pipe or the like.
Since the water-supplying hose 12 is used for rinse water supplied to the body 20 of the toilet device, a vinyl hose having a small diameter or the like may be used. Since the drain hose 14 enables any liquid mixture (fragments) formed by breaking the excrement and the like to be flown therein, a vinyl hose or the like having a larger diameter than that of the water-supplying hose 12 may be used. This is because liquid mixture with the rinse water, not solidified excrement, is treated.
If diameters of the water-supplying hose 12 and the drain hose 14 are so selected as to be become the diameters described above, rudimentary mistake in connection manipulation such that the water-supplying hose 12 is used as a drain hose or the drain hose 14 is accidentally connected as a water-supplying hose may be certainly prevented because of difference in their diameters. Of course, not only in a case where hoses having different diameters are used but also in a case where hoses having same diameter are used, as shown in
The connection portions 60 (62), each of which has a check valve, form a hollow valve operation room 64 with a rectangular profile inside a body 63, as shown in
On the other hands, when the other connection portions 60B (62B) of the connection portions 60 (62) are connected to a side of the portable toilet device and a side of drain pipe of the existing toilet device, for example, their internal valves are opened to become any communicate condition in a case where the connection portions 60 (62) are connected if projection members, not shown, each retreating the ball member 65 of the check valve against the push spring 66, are respectively provided in the side of portable toilet device and the side of the drain pipe, or when they are not connected, their internal valves are closed to prevent liquid in each of the hoses from leaking to outside.
Therefore, even if the connection portion 60A is detached while the connection portion 60A of the water-supplying hose 12 is connected to the water supply pipe and the connection portion 60B thereof is connected to the side of the body 20 of the toilet device, any liquid in the hose is not leaked; and even if the other connection portion 60B is detached, any liquid in the hose is not leaked. Similarly, even if the used drain hose 14 is detached, any waste liquid in the hose is not leaked to outside.
In this embodiment, the diverging pipe 84 having such the diverging configuration is used. A check valve 90 is arranged between the first and second diverging ports 86, 88 and a connection portion 92 for connecting the water-supplying hose 12 is provided at a tail end of the diverging pipe 84. The connection portion 60A provided at a tip end of the water-supplying hose 12 is connected to this connection portion 92.
Thus, arranging the new diverging pipe 84 and attaching the water-supplying hose 12 thereto enables the rinse water to be supplied to the portable toilet device 10. It is because if an error such that water from the hose 89 and the water-supplying hose 12 flows backward should happen, the water to be supplied to a side of the shower toilet is prevented from being mixed with the water flown backward, to arrange the check valve 90 between the first and second diverging ports 86, 88.
A tank 96 filled with a sterilizing solution is further able to be inserted to a connection portion for the sterilizing solution at the tail end portion of the diverging pipe 84. Using the sterilizing solution enables any sanitary conditions in not only the existing toilet facility 3 but also the portable toilet device 10 to be improved. The drain hose 14 may be also washed at the same time. The pour-water tank 96 has not always to be provided but may be suitably provided at need.
The drain hose 14 may be arranged as to drain the waste water and the like directly to the drain pipe, for example, the drain pipe in the existing toilet facility 3 but, in a simple case, the drain hose 14 extends to the toilet device 4 and the waste water and the like pour directly into the toilet device 4. Alternatively, a drain outlet for drain is provided in the toilet device 4 and the drain hose 14 is connected to it so that the waste water and the like can pour into the toilet device 4 therethrough. An embodiment shown in
Thus, by utilizing the existing toilet facility 3, it is possible to supply water to the portable toilet device 10 and drain from the portable toilet device 10 if a simple work to attach only the diverging pipe 84 is carried out.
The portable toilet device 10 according to the invention further has the following configuration. As shown in
The means 200 may be constituted of an air compressor and a sending pipe 204 of the air compressor 200 extends through the wall surface 18a into the side of the stagnant portion 18 via attaching means 206. The attaching means 206 is positioned at a position upper than a surface of trap water in the stagnant portion 18. The air compressor 200 is fixed on an attaching plate 202 provided in the back-side space 20a of the body 20 of the toilet device. Similarly, in order to demonstrate the same function as the means 200 to supply prescribed compressed air to the stagnant portion 18, it is possible to take the compressed air therein from outside of the body of the portable toilet device and to demonstrate the same faculty.
The lid-opening and closing mechanism 210 exists in a position upper than the means 200 for sending the broken excrement by compression, and positioned away from the means 200 by a small amount of allowed distance. The lid-opening and closing mechanism 210 shown in
As how to open and close the lid body 212, slidable type one and open/close (rotational) type one to open and close it upwardly or downwardly by an angle of more than 90 degrees as one example are conceivable, so that the open/close driving portion 213 may have different configurations depending on the slidable type one or the rotational type one.
The embodiment shown in
The lid body 212 has a form of plane that corresponding to an internal circumference form of the stagnant portion 18, as an example thereof shown in
In this example, the lid body 212 and the connection portion 214 are cast together so that a part of the lid body 212 can be formed as the connection portion 214. The connection portion 214 has a rectangular form. A tip end of the above-mentioned piston 216 is fit and fixed by means of press fit to an opposite side of the connection portion 214. The piston 216 is an operation column rod that is advanced and retreated inside the electromagnetic solenoid 218 by turning the electromagnetic solenoid 218 on electricity. In addition thereto, a combination of an air cylinder and gears or the like can perform the same advanced and retreated movement for open and closure.
Such the advanced and retreated movement for the lid body 212 is performed by turning the electromagnetic solenoid 218 on or off and its stroke is detected by a first switch 222 that is positioned at the electromagnetic solenoid 218 on its side of the lid body 212 and a second switch 224 that is positioned at the body 20 of the toilet device on its side of the wall surface 18a. Attaching the connection portion 214 to the first or second switch 222, 224 enables a stroke termination of the lid body 212 to be detected.
Slide and connection of the lid body 212 toward an upper surface of the stagnant portion 18 causes an interior of the stagnant portion 18 to be closed tightly. It is not necessary to close the interior of the stagnant portion 18 tightly to the full. Under this closed condition of the lid, if the air compressor 200 is driven, compressed air is sent into the stagnant portion 18 so that any pushing pressure can be applied to the trap water and any broken matters in the stagnant portion 18 can be sent to a side of the drain hose 14 by compression. It is to be noted herein that the broken matters indicate to a liquid mixture of the broken excrement and the trap water.
Since the stagnant portion 18 is thus closed tightly by the lid body 212, the compressed air affects the side of stagnant portion 18 effectively. Since the broken excrement becomes liquid mixture, the liquid mixture can be easily drained together with rinse water through the drain hose 14 when the compressed air affects the stagnant portion 18.
Thus, the liquid mixture is prevented from being remained in the drain hose 14. The liquid mixture is sent by compression while the stagnant portion 18 is closed tightly so that a relatively small-sized compressor may be used as the air compressor used as the means 200 for sending by compression. Using the lid-opening and closing mechanism 210 enables the excrement to be prevented from being spilt into the body 20 of the toilet device when breaking the excrement into fragments, so that no unhygienic environment may occur in the body 20 of the toilet device.
The power switch 52 is turned on when the portable toilet device 10 is installed. On the other hand, the detection switch 55 for open and closure is a switch that is turned on/off in connection with the open and closure of the cover 23 for closing an upper portion of the seat 21. Therefore, as shown in
Any control signals from the control unit 50 constituted of CPU control each driving state of the above-mentioned electromagnetic valve 24 for drain, electromagnetic valve 32 for water supply, motor 42 for breaking, air compressor 200, and electromagnetic solenoid 218.
The portable toilet device 10 is used by opening the cover 23. Open manipulation of the cover 23 is detected by the detection switch 55 (detection sensor switch or the like) for open and closure (
The lid body 212 is opened so that the toilet device can be used and when bowel movement and/or urination are finished and the cover 23 is closed, the detection switch 55 for open and closure detects it to close the lid body 212. Alternatively, when an electric signal by a manual switch notifies the control unit that bowel movement and/or urination have been finished, the lid body 212 is closed. The stroke Tx of the lid body 212 in a closure direction thereof is detected by the second switch 224 (
When the lid body 212 is closed so that an interior of the stagnant portion 18 is closed tightly, the motor 42 for breaking is now activated to start the breaking process in the stagnant portion 18 (
The breaking process is performed during only a predetermined period of time Ta and then, the air compressor 200 is turned on to send the compressed air into the stagnant portion 18; and the electromagnetic valve 24 for drain is opened to create a drain passage (
As the predetermined period of time Tb, a relatively longer period of time, for example, about 10 through 30 seconds are normally selected so that any liquid mixture may not be remained in the drain hose 14, though there may be differences in connection with lengths of the set drain hose 14.
When the predetermined period of time Tb has been elapsed, it is now moved to the open operation of the lid body 212 (
When the water supply into the stagnant portion 18 has been completed, the lid body 212 is closed so that it can be returned to its initial state (
By setting such the operation timings, breaking the excrement into fragments, the drain process, and the trap process of the trap water may be accomplished. It is to be noted that any drain switch, not shown, may be provided for opening the electromagnetic valve 24 to drain the trap water by manually operating it in order to be made suitable when the portable toilet device 10 is carried or the like.
The above-mentioned open/close timings and the like of the electromagnetic valves and the like are only their examples. Alteration may be suitably added thereto. For example, as shown in
In order to realize that the attaching cap 67 can be closed in a hermetic manner against water, a bottom of the stagnant portion 18 that is contacted with the cover plate 68 is recessed somewhat and the cover plate 68 is fixed to the bottom of the stagnant portion 18 by means of screws 70 and the like. Thus, the means 40 for breaking can be also attached. It is to be noted that although it has been described that the motor 42 and the crushing blades 44 constitutes the means 40 for breaking, a screw, a blade, or a cylindrical roller with projections on its circumference or the like may be configured instead of the crushing blades and a configuration in which a rotational shaft of the motor is arranged horizontally may be configured.
The following will describe another embodiment (embodiment 2) of the portable toilet device 10 according to the invention with reference to
As shown in
The reducing size portion 260 is so designed as to be wholly inclined somewhat toward a side of the drain portion 22, as clearly shown in
The lid-opening and closing mechanism 250 has a lid body 252 and an end of the lid body 252, a right end thereof in a shown embodiment, is provided as a rotation axis portion 214 for rotational type; the rotation axis portion 214 is pivoted rotatably on the body 20 of the toilet device so that the rotation axis portion 214 can be positioned under a lower surface portion 232 of the reducing size portion 260. This pivoted portion is pivoted under the body 20 of the toilet device in a hermetic manner against water.
The lid body 252 is urged so that its periphery can come into contact with a lower rim 264 of the reducing size portion 260. The lid body 252 has a form like along that of the lower rim 264 and a spring 256 for urging is twisted between the rotation axis portion 254 and a wall surface of the lower surface portion 232, thereby enabling the lid body 252 to be come into contact with the lower rim 264 normally to close the interior of the stagnant portion 18 tightly.
Herein, since the reducing size portion 260 is provided so as to be inclined somewhat toward the drain portion 22 as described above, the lid body 252 itself constituting the lid-opening and closing mechanism 250 is also attached so as to be inclined toward the drain portion 22. Thus, when the lid body 252 is attached in an inclined manner, any excrement dropped on an upper surface of the lid body 252 can be dropped dawn into the stagnant portion 18 (see
The lid-opening and closing mechanism 250 is thus configured so as to be rotated so that any driving mechanism as shown in
A tip end of the above-mentioned washing hose 240 is attached inside the stagnant portion 18 with an angle being able to jet rinse water into both of a side of rear surface of the lid body 252 and a part of the periphery of the stagnant portion 18. In this embodiment, as shown in
In an example of control timing of
After the bowel movement has been finished, the cover is closed (
When the breaking operation has been finished, an air compressor 200 is driven to send compressed air into an interior of the stagnant portion 18 which is then pressed (
When the period of time Tb has been elapsed, the electromagnetic valve 24 for drain is driven while the air compressor 200 is driven, namely, the compressed air is sent to the interior of the stagnant portion 18 (
A period of time Tc for sending-by-compression is normally set to a period of relatively longer time, for example, about 10 through 30 seconds, in order to prevent the liquid mixture from being remained in the drain hose 14, though there may be a difference in a set length of the drain hose 14.
When the period of time Tc has been elapsed, the electromagnetic valve 24 for drain is turned off and driving of the air compressor stops (
It is to be noted that, in this embodiment, an electromagnetic valve 33 for washing is also driven with synchronization with the operation of the electromagnetic valve 32 for water-supply, as shown in
Such the washing process may be performed before the water supply to the stagnant portion 18, namely, after the liquid mixture has been sent by compression and drained, not simultaneous execution of the water supply to the stagnant portion 18 and the washing of the lid body 212 and the like, to send and/or drain the rinse water therefor at the same time. Therefore, the water supply to the stagnant portion 18 is then performed after the electromagnetic valve 24 has been closed.
If the portable toilet device 10 is moved or removed, it is preferable to drain the trap water from the stagnant portion 18. Such the drain processing is separately performed from the above-mentioned drain process. In this case, as shown in
This sending-by-compression enables the trap water to be drained from the stagnant portion 18. The electromagnetic valve 24 for drain is closed with a small amount of delay (ΔTf) starting from when the driving of the air compressor 200 stops. This causes any drain processing of the trap water to be completed. It is to be noted that the period of time Tf may be set to the above-mentioned period of time Tb and the period of time Tg may be set to the period of time Tc.
The means 200 for sending-by-compression is utilized for crashing process of the excrement and the like in addition to sending the excrement and the like by compression. An air compressor of small size is used as the means 200 for sending-by-compression. The means 200 for sending-by-compression is attached and fixed to a predetermined position inside the body 20 of the toilet device.
The sending pipe 204 is connected to the means 200 for sending-by-compression and a jet outlet 206 is fixed at a position of the stagnant portion 18, which is positioned upper than a surface of the trap water in the stagnant portion 18, with the jet outlet being exposed on the side of the stagnant portion 18. In this embodiment, the jet outlet 206 is attached and fixed with it being inclined somewhat, so that the jet outlet 206 can face toward a side of the surface of the trap water.
The diverging pipe is used as the sending pipe 204 and a jet outlet 207a of a diverging branch pipe 207 is positioned at a side of the bottom of the stagnant portion 18 with the jet outlet being exposed therein. The jet outlet 207a is attached and fixed with it being inclined somewhat, so that the jet outlet 207a can face toward a side of the wall surface of the stagnant portion 18, not face just above in the stagnant portion 18. This is because the excrement can easily crash to the wall surface of the stagnant portion 18 with the excrement being stirred by the jet stream based on the compressed air jetted from the jet outlet 207a.
The excrement drops into the stagnant portion 18 when an opening/closing lid 252 is opened by its weight, as shown in
In order to enhance crushing power to the excrement by the jet stream, in the embodiment shown in
The crushing portion 270 is constituted of a plurality of projections 272 and in this embodiment, the plurality of projections 272 is so configured as to be regularly formed as several lines. It is preferable that the projections have a sharp pinnacle form to make the excrement easy to crash when the excrement is run crash into these projections 272.
Numbers, length, thickness, set line number and the like of the projections 272 constituting the crushing portion 270 are optional. Their material is also optional but plastic mold articles are preferable therefor. This is because, if they are plastic mold articles, the crushing portion 270 is produced at a low price and its attachment to the wall surface of the stagnant portion 18 is also performed by utilizing a binder or the like so that any execution can be easily carried out.
Thus, it is possible to perform any crashing process effectively on the excrement by utilizing the jet stream using the means 200 for sending-by-compression and then allowing the excrement and the like to crash utilizing the means 200 for sending-by-compression and the crushing portion 270, particularly utilizing the crushing portion 270.
Any control signals from the control unit 50 control each driving state on the above-mentioned electromagnetic valve 24 for drain, electromagnetic valve 32 for water-supply, and air compressor 200 as the means for sending-by-compression.
The detection switch 55 for open and closure is provided in connection with the washing button 274, which will be next described. This is because it is prevented from performing any washing process even if the washing button 274 is manipulated before the cover 23 is opened. Thus, this detection for open and closure may be provided as occasion demands.
After the bowel movement has been finished, the cover is closed; the washing button 273 is then pushed down (
The compressed air is respectively supplied to an upper space into the stagnant portion 18 and the trap water simultaneously. The excrement exposed on a surface of the trap water is attached to plural projections 272 by compression with the excrement being first dropped into the trap water by pressure of the compressed air sent into the upper space. The jet stream by the compressed air sent into the trap water causes any water current, by which the trap water is flown round in the stagnant portion 18.
Since a jet direction of the compressed air is set so that the compressed air is jetted toward a side of the wall of the stagnant portion 18, the excrement crashes to an inner wall of the stagnant portion 18 by means of the water current by the compressed air. There are plural projections 272 in this inner wall so that the excrement crashes to the projections 272. The trap water is flown round, so that the excrement is flown with it crashing to the projections 272 over and over. Such the flow allows the excrement to be broken into fragments. Since the excrement contains moisture from the trap water, it easily crumbles.
Therefore, sending the compressed air to the stagnant portion 18 for a predetermined period of time Ta starting from a point of crash-starting time t1 enables the excrement to be broken into fragments, as shown in
Since the tightly closed upper space in the stagnant portion 18 is almost closed by the opening/closing lid 252 so that an electromagnetic valve 24 at a side of the drain opening 27 is closed for a period of the breaking process time (points of time t1 through t2), as shown in
The control unit 50 counts a period of time from the point of time t1 when the washing button 274 is manipulated so that when the period of crash-processing time Ta has been elapsed at (point of time t2), the process then shifts to the washing process automatically (
When the drain opening 27 is released, any internal pressure (about 2 atmospheric pressures) in the stagnant portion 18 enables the broken excrement (broken mixture) to be drained (sent by compression) to a side of the drain hose 14 once together with the trap water that has been trapped and rinse water that is newly supplied from a side of the water-supplying nozzle 28 (
While the washing process goes on for the period of time Tb starting from the point of time t2 up to the point of time t4, the drain process is assigned to a shorter period of time Tc than the predetermined period of time Tb by Td (
Although in the embodiment shown in
In this embodiment, the breaking process mode starts preceding the washing and draining process mode somewhat. It is because the breaking (crashing) effect to the excrement can be enhanced if the compressed air is previously sent to precede the breaking process mode.
Although in
Thus, a base 292 is set inside the toilet device 20 and a water-supply tank 290 is fitted on the base 292 as shown in
When the water-supply tank 290 is thus newly provided to discharge the rinse water together with the compressed air from the bottom of the stagnant portion 18 into the trap water, the trap water is made as high-speed water current so as to crash to the side water of the stagnant portion 18. Since there is crashing means 270 in the side water of the stagnant portion 18, the excrement crashes to this crashing means 270, so that the excrement is flown round in the stagnant portion 18 together with the trap water in cooperation with a spray of the compressed air, the water current and water pressure of the trap water while the excrement crashes to the projections 272, thereby enabling the excrement to be effectively broken into fragments at a short time.
Breaking and draining processes shown in
In such a case, if it is supposed that the room can include six care-receivers, the beds 96 are arranged as shown in
This enables plural users to be treated. It is to be noted that though in this case, of course, a diameter of the drain hose 14 having a small diameter can be used.
In this moment, a main body 108 of the existing toilet device 4 is modified. In
It is to be noted that if the existing toilet device 4 is thus modified, any liquid mixture may be remained in the drain hose 14 when the existing toilet device 4 is set at a higher position in a case where the portable toilet device 10 and the existing toilet device 4 are set with a difference of altitude. If, however, the above-mentioned air compressor 200 is provided and the liquid mixture is sent by compression by means of its compressed air, this prevents this liquid mixture from being remained in the drain hose 14.
Thus, this trapping lid 116 is preferably trapped in an electric powered manner and is controlled so as to be opened or closed simultaneously as the electromagnetic valve 24 for drain in the portable toilet device 10 is operated. If the trapping lid 116 is configured so as to be slidable as shown in
If a system such that the trapping lid 116 is opened or closed, not being slid, to have an angle of 90 degrees or more, as one example, is employed, a shaft-driving mechanism is provided for a rotation shaft of the trapping lid 116 and its rotation is controlled simultaneously as the electromagnetic valve 24 is operated. A system that can open or close it simultaneously as a cover (an outer cover for closure of the toilet seat) provided on the main body 108 of the toilet device, not cooperation with the electromagnetic valve 24, may be employed.
Since the trapping lid 116 must be opened or closed even if the existing toilet device 4 is used, the trapping lid 116 may be configured so that if the existing toilet device 4 is equipped with a toilet seat with shower toilet, an opening/closing detection switch, not shown, is provided on the toilet seat with shower toilet and the trapping lid 116 is controlled by using a control signal based on its switch manipulation.
In
In this case, a connection portion to be connected to a connection portion 62B provided on the drain hose 14 is installed in the hole 119. Further, if the existing toilet device 4 is used, the drain hose 14 must be detached therefrom.
A piping such that a tip end of the drain hose 14 can reaches the stagnant portion is approval and a piping such that a tip end of the drain hose 14 can has a length enough to extend slightly from the toilet seat 108 is also approval. Since the drain pipe 14 has a small diameter, it can be attached and fixed by using the space formed between the main body 108 and the toilet seat 118.
In this moment, as shown in
An attachment 128 for the drain hose 14 is integral with a portion of the attaching and fixing member 120, which faces a side of the drain portion 110 when inserting it, and at forward end thereof, an attachment portion 128a that is folded at 90 degrees or more in a shown condition, is provided. The attachment portion 128a is provided with a grip (inserting) portion 134 having an open end. A large opening 130 is formed on the surface thereof facing the drain portion 110.
The attaching and fixing member 120 thus configured is inserted into the stagnant portion of the main body of the toilet device so that the opening 130 can face the drain portion 110. Such the insertion enables the attaching and fixing member 120 to be fixed to the stagnant portion with them being tightly attached to each other. The forward end of the drain hose 14 is then attached and fixed to the grip portion 134 of the attachment portion 128a as shown in
It is to be noted that if the attaching and fixing member 120 has not enough elasticity, pipe member for enlargement by which an inner hollow portion of the attaching and fixing member 120 is enlarged may be used. By inserting such the pipe member into this inner hollow portion, it is possible to attach and fix almost whole of the attaching and fixing member 120, the inner hollow portion of which has been enlarged, to an internal circumference of the stagnant portion tightly.
The attaching and fixing member 120 is fitted and fixed to Japanese toilet device 180 by expanding (widening) both ends of the holding portion 136 and utilizing its elastic force. Using such the attaching and fixing member 120 enables the drain hose 14 to be attached and fixed with it facing the stagnant portion.
The attaching portion 138 of the drain hose 14 may be provided at not only the middle of this holding portion 136 but also a side of any of the ends of the holding portion 136 with it being shifted to any of right and left.
Since the air compressor 200 is provided at an upper position of the stagnant portion 18 as shown in
Means for forcing, not shown, the tank 142, is operated for a period of predetermined time Tb when the toilet is used, specifically to link the drain timing of the liquid mixture. This enables a predetermined antiseptic solution to be sent to the stagnant portion 18 by forcing the tank 142 only when using the toilet.
Thus, a portion of the body 20 of the toilet device near the stagnant portion 18 is always antisepticised by the antiseptic solution so that it can be sanitary. By dropping the antiseptic solution thereinto, the drain hose 14 is also antisepticised at the same time, thereby enabling any much sanitary portable toilet device to be provided.
The ventilation fan 152 is driven in rotation at least when using the toilet. Thus, air within the body 20 of the toilet device can be inhaled and exhausted to outside so that any smell from the excrement can be efficiently exhausted to outside. Accordingly, any smell from the excrement is prevented from being drifted in a room, thereby allowing any comfortable environment to be realized.
On the other hand, a hole 168 having a smaller diameter than that of the opening 164a is also formed on the frame 162 opposite to the opening 164a, and shutters 170 for operating to shut the hole to link each other are provided.
The portable toilet device 10 is attached and fixed to a side of the lower surface of the frame 162 so that it can close the hole 168.
When the portable toilet device 10 is used while a patient lies down in the bed 160, the cover 166 constituting the mattress is opened and the shatters (electric-power shutters) 170 for open and closure are also opened. This causes the portable toilet device 10 to be ready for use. Preferably, if an incline of the frame 162 can alter by electric power, the portable toilet device 10 is easy to be used by inclining the frame 162.
The shutters 170 for open and closure are configured as shown in diagram so as to use a pair of shutter plates that can be opened or shut back and forth and make them opened and shut to link each other. Alternatively, it can be configured so as to use one shutter plate that can be opened or shut by rotating it by more than 90 degrees on the same plane.
This invention is preferably applicable to a nursing-care assisted appliance for any nursing-care facilities, home-based care or the like.
