[Problems to be solved by the invention]
In the method of mixing solid particles in warm water and fluidizing them by collision with the body as described in the above publication, the ratio of the specific gravity of water and solid particles is as low as about 3: 1 and there is also resistance to water solid particles. Thus, it is difficult to fluidize the solid particles so as to obtain a cleaning effect in water. That is, the friction / collision action between the solid particles and the skin is small, and the cleaning effect is weak. Furthermore, in order to enhance the cleaning effect by this method, it is necessary to use a large amount of hot water. Therefore, not only a large amount of water but also a large amount of heat source is required, and an apparatus that can be easily transported is realized. Hateful.
[0004]
In order to reduce the amount of hot water used, for example, a circulation type may be used. In that case, the waste water after washing is passed through a filter to remove solids such as dirt and hair, and then the hot water is sterilized through a sterilizer. There is a need to. However, it becomes an excessively large apparatus, and it is extremely difficult to remove the soil components dissolved in the hot water, and the hygiene problem cannot be solved completely.
[0005]
Furthermore, in consideration of an earthquake disaster, an apparatus that can clean the body without using water or with a very small amount of water is desired. Although it is desirable that it can be easily moved, the conventional example cannot satisfy such a demand.
[0006]

[0025]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0026]
FIG. 1 is a side view of the embodiment of the present invention in use, and FIG. 2 is a plan view thereof. In this embodiment, a care recipient or a person who is difficult or impossible to wash himself / herself (for example, a care recipient or a person with a disability in the lower body, arms or hands) 10 is caused to sit on a wheelchair 12. It is a bathing apparatus that can take a bath as it is, and the body surface is washed by the particles 18 fluidized in the bathtub 14. The top view of the bathtub 14 is shown in FIG. 3, and sectional drawing seen from the AA line of FIG. 3 is shown in FIG. FIG. 5 is a sectional view taken along line BB in FIG.
[0027]
The usage will be described while explaining the configuration and the function of each part. The bathtub 14 is provided on a door 16 that can be freely opened and closed on one side wall as shown by a broken line in FIG. 1, and a care recipient 10 who is in a wheelchair can easily roll the wheel of the wheelchair 12 into the bathtub 14. You can go in and out. That is, the open / close door 16 on the side of the bathtub can be lowered and raised with the lowermost part as a fulcrum. In the closed state, the door 16 needs to be sealed so that air and water do not leak between the adjacent side walls and the bottom surface. A plate-like packing made of rubber or foamed plastic is attached to the contacting part such as other side walls, etc., and fastening tools using springs at a total of four places on the side wall of the bathtub 14 in contact with the door 16 in the vertical and horizontal directions. Is attached. Thereby, in the state which closed the door 16, the leak of air and water can be prevented completely.
[0028]
In this embodiment, the bathtub 14 has no ceiling surface and is open. However, the bathtub 14 may be a box with the ceiling surface closed, or a room that can be closed like a bathtub in a normal bathroom. It may be installed in.
[0029]
A slightly perforated plate 20 that allows air to pass but does not pass through the granules 18 used for body washing is disposed slightly above the bottom surface of the bathtub 14. As will be described later, the particles 18 are spouted and fluidized in the bathtub 14 through the air from the bottom to the top of the perforated plate 20 (usually hot air is used, but water vapor may be used instead of hot air). It is supposed to be made. The behavior of the particles 18 in the bathtub 14 will be theoretically described later.
[0030]
The granule 18 used in this example has a diameter of about 0.5 to 10 mm, iron (specific gravity 7.9), alumina (specific gravity 3.7), ceramics (specific gravity 2.6), and plastic (specific gravity). Some of 1.2) are used together. A granule with a large specific gravity is reduced in diameter, and a granule with a low specific gravity is increased in diameter, so that the free fall termination speed of one granule, that is, the blowing speed U for ejecting the granule becomes almost constant. Adjust as follows. A combination of granules is appropriately selected according to the preference of the person to be cleaned.
[0031]
The door 16 of the bathtub 14 is opened, the bather 10 is put into the bathtub 14 while riding on the wheelchair 12, and the stopper 22 is raised so that the wheelchair 12 does not return. This is because the porous plate 20 is inclined so as to be lowered toward the door 16 for the reason described later. If the perforated plate 20 is inclined forward, a stopper is placed on the front side. The standing and returning of the stopper 22 may be operated by others, but it is preferable that the bather 10 can operate it. For this purpose, an operating lever may be provided at an appropriate position in the bathtub 14. Then, the door 16 is closed. These operations can be performed by the bather 10 by themselves, but even if the other person's help is necessary, the user basically pushes the wheelchair 12 and is extremely easy.
[0032]
With the door 16 sealed, the valve 26 of the granule washing tank 24 placed on the upper part of the bathtub 14 is opened, and a predetermined amount of clean granule 18 is supplied from the granule washing tank 24 into the bathtub 14. The blower 28 and the heater 30 are operated, the valves 32, 34 and 36 are opened, and hot air is supplied into the bathtub 14. The warm air that has passed through the valve 34 is supplied under the perforated plate 20 and blows up the particles 18 on the perforated plate 20. The warm air that has passed through the valve 36 is jetted into the bathtub 14 from a number of nozzles 38 that are arranged on the side of the bathtub 14. By blowing out from the nozzle 38, fluidization of the particles 18 can be promoted. As shown in FIG. 2, the nozzle 38 is provided on the side surface in addition to the front surface of the bather 10. Further, a similar nozzle 38 may be provided on the back surface (that is, the door 16).
[0033]
In parallel with the fluidization of the granules 18, a small amount of washing liquid is sprayed on the bather 10 to wet the body. That is, the cleaning liquid is stored in the cleaning liquid tank 40, and the cleaning liquid is sprayed near the chest of the bather 10 through the valve 42, the flexible tube 44, and the spray nozzle 46 at the tip of the flexible tube 44. 48, the flexible pipe 50, and the spray nozzle 52 of the front-end | tip of the flexible pipe 50 are sprayed on the bather's 10 vicinity. The flexible tube 50 is taken out from the bottom surface or the side wall of the bathtub 14, and can change the position and orientation of the spray nozzle 52 to some degree of flexibility. Thereby, a cleaning liquid can be sprayed freely. When the necessary cleaning liquid is discharged, the valves 42 and 48 are closed.
[0034]
If a porous material is used as the granular material 18 and the cleaning liquid is absorbed in the interior thereof, it is not necessary to spray the cleaning liquid on the body of the bather 10.
[0035]
The fluidized granules 18 collide and rub against the body of the bather 10 to rub the skin, and in combination with the action of the cleaning liquid, the body can be cleaned. By appropriately controlling the wind pressure of the hot air supplied under the perforated plate 20, the fluidized granules 18 can be prevented from blowing up to the head of the bather 10 and above. Further, an air suction port 54 is provided on the side wall of the bathtub 14 at a height per shoulder of the bather 10 so as to return to the blower 28. Thereby, the unnecessary blowing of the granule 18 which reaches the bather's 10 face can be prevented. Of course, the air suction port 54 is provided with a filter for preventing passage of the granules 18. Furthermore, a lid with an opening that exposes the head of the bather 10 to the outside and does not obstruct the injection of the cleaning liquid by the spray nozzle 46 may be prepared.
[0036]
When the dirt and dirt attached to the body are released from the body, that is, when the washing is completed, the valve 32 is closed and the heater 30 is stopped. When the valve 32 is closed, the hot air is not supplied, and the flying particles 18 sink. By disposing the perforated plate 20 so as to be slightly lowered toward the lower portion of the door 16 (about 3 to 6 degrees), the particles 18 are accumulated in that portion of the bathtub 14. A groove 56 is provided at the accumulation position so that the particles 18 can be easily stored. In FIG. 1, a pipe opening for putting the granule from the granule washing tank 24 into the bathtub 14 is located at the upper part of the groove 56, but this is for the convenience of drawing, and actually the front of the bather 10. The granules 18 are placed in the bathtub 14 near the wall.
[0037]
The width of the groove 56 is usually narrow enough that the wheel of the wheelchair 12 does not drop off, but if there is a risk of dropping off, a wheel support plate for preventing it may be appropriately disposed on the groove 56. Although the groove 56 is open, it may be covered with a lid having a number of holes or openings through which the granules 18 can fall into the groove 56.
[0038]
As shown in FIG. 5, the bottom surface of the groove 56 is inclined by 3 to 4 degrees, and the discharge hole 60 is provided at the end in the longitudinal direction of the groove 56 at the lowest position. The discharge hole 60 is connected to the granular material washing tank 24 through a rotary valve 62, an air transport pipe 64 and a valve 66. The rotary valve 62 includes a rotor having a cross-shaped wing inside, and the tip of the wing is in close contact with the inner wall of the casing, so that the particles 18 can be dropped while preventing the backflow of air. . An air transport pipe 67 is connected to the air transport pipe 64 immediately below the rotary valve 62 so that the output air of the blower 28 is exclusively inserted into the air transport pipe 64. An air transport pipe 68 branched from the air transport pipe 67 is connected to the opening of the groove 56 at the end opposite to the discharge hole 60. A valve 70 is installed between the blower 28 and the air transport pipes 67 and 68 to prevent unnecessary air blowing.
[0039]
When the valves 66 and 70 are opened, the output air from the blower 28 is supplied to one end of the groove 56 via the air transport pipe 68 and also supplied to the lower side of the rotary valve 62 via the air transport pipe 67. The By the air supplied through the air transport pipe 68, the particles 18 in the groove 56 are sent toward the discharge hole 60. The air supplied by the pneumatic transport pipe 67 cannot pass through the rotary valve 62 and enters the pneumatic transport pipe 64 exclusively, and becomes a negative pressure for the rotary valve 62. Combined with the air blow by the air transport pipe 68, the particles 18 in the groove 56 can be efficiently discharged, and can be conveyed to the particle cleaning tank 24 through the air transport pipe 64. The blowing speed by the air transport pipe 68 at this time is 10 m / s or more, preferably 15 to 20 m / s.
[0040]
The granule washing tank 24 is equipped with a stirrer 24a and a motor 24b for rotating the agitator 24a. Tap valve 72 is opened to supply tap water from the top, water is added to about half the height of the internal granule 18, and a bactericidal agent is added at the same time, and agitator 24a is rotated by motor 24b. Thereby, the granular material 18 is wash | cleaned and disinfected. Dirty water is discharged from the lower part of the granule cleaning tank 24 to the outside through a valve 74 different from that for taking out the granule 18. Of course, the valve 74 allows water to pass but prevents the particles 18 from passing. For example, the valve 74 is equipped with such a filter. The cleaned particles 18 are stored in the particle cleaning tank 24 for the next use.
[0041]
In the case where a porous material that has absorbed the cleaning liquid is used as the particles 18 and the cleaning liquid is not sprayed on the bather 10, the cleaning liquid is injected into the particle cleaning tank 24 after the particles 18 are cleaned. Then, the cleaning liquid is absorbed in the granules 18.
[0042]
A shower nozzle 76 is arranged above the bather 10. When the valve 77 is opened, tap water is supplied to the instantaneous water heater 78. By operating the instantaneous water heater 78 and opening the valve 80, a hot water shower raised to an appropriate temperature can be applied from the head. Now you can wash your head and face. By opening the valve 82, hot water from the instantaneous water heater 78 is also supplied to the bubbles 34 and 36. When the valve 32 is closed and the valves 34 and 36 are opened, hot water is supplied under the perforated plate 20 and is simultaneously ejected from the nozzle 38 toward the bather 10. With the hot water supplied under the perforated plate 20, the particles 18 remaining on the perforated plate 20 are poured out. The hot water ejected from the nozzle 38 reaches the body surface of the bather 10, thereby rinsing and warming the body surface of the bather 10 cleanly. Thereafter, this hot water is discharged to the outside from the drain port 84 on the bottom surface of the bathtub 14. At this time, the valve 86 is kept open.
[0043]
The shower is stopped and the valve 82 is closed. Next, the blower 28 and the heater 30 are operated, and the valve 32 is opened. Thereby, warm air is blown out from the bottom of the porous plate 20 and from the nozzle 38, and the body of the bather 10 inside is dried. When the body is dry, the door 16 is opened, the stopper 22 is removed, and the bather 10 can go out of the bathtub 14 by himself while sitting on the wheelchair 12.
[0044]
In the present embodiment, as clearly shown in FIG. 4, the perforated plate 20 is inclined by about 3 to 6 degrees so as to become lower toward the opening / closing door 16 side. When discharging while maintaining the liquefied state, if this degree of inclination is not provided, a part of the particles 18 is not discharged and remains on the bottom of the bathtub 14 (that is, on the porous plate 20). It is for preventing. The porous plate 20 may be lowered to the front side, and the used particles 18 may be collected on the front side of the bathtub 14. In that case, warm air is supplied from the side of the door 16 or from the left and right side walls close to the door 16.
[0045]
The spray nozzle 44 for spraying the cleaning liquid is preferably a system in which air (preferably hot air) is mixed with the cleaning liquid and ejected from a small orifice by the spraying principle. In such a structure, since the cleaning liquid can be made into fine particles and the spray angle can be increased (90 to 120 degrees), the cleaning liquid can be uniformly and widely adhered to the body.
[0046]
In the said Example, although the air suction opening 54 is discretely provided in the three side walls of the bathtub 14, it shows with the longitudinal cross-sectional view in FIG. 6, and the cross-sectional view seen from CC line of FIG. In the same manner, a duct 88 that protrudes outward is provided at the same height, and the inside thereof is closed with a screen 90 or a filter that prevents passage of the granules 18, and a hole 92 provided at an appropriate location of the duct 88 is formed. The air suction pipe 94 is connected to the air intake port of the blower 28 through the air suction pipe 94. As a result, the air at the height of the duct 88 is sucked out of the duct 88, so that the fluidized granules 18 are prevented from reaching the portion above the shoulder of the bather 10, particularly the mouth and ears. The bather 10 can inhale fresh air that does not contain the granules 18. The screen 90 can prevent the particles 18 in the bathtub 14 from being discharged to the outside, and can also prevent the blower 28 from breaking into the blower 28.
[0047]
In this embodiment, the fluidized granules 18 are rubbed against the body to clean the body surface.
Therefore, the seating surface (and the backrest) of the wheelchair 12 has a mesh shape or a perforated plate shape having a large number of openings larger than the diameter of the particles 18 so that the particles 18 can widely contact the body surface. Preferably it is. Of course, if the bather 10 can move his / her body a little and separate from the seat and back portion of the wheelchair 12, the cloth-like one may be used.
[0048]
Here, the behavior of the particles 18 in the bathtub 14 will be briefly described. FIG. 8 shows the upward empty tank velocity (fluid average cross-sectional velocity of the bathtub 14 calculated as an empty tank) Uf for fluidizing the layer (granular layer) composed of the granular material 18 and the pressure loss of the granular layer. The relationship is shown. The vertical axis indicates the pressure loss ΔP, and the horizontal axis indicates the empty tank speed Uf.
[0049]
  As the vertical velocity Uf when the gas passes through the granular layer is increased from 0, the pressure difference between the bottom of the granular layer and the upper part of the granular layer, that is, the pressure loss ΔP increases. When Uf reaches a certain size Umf, the granular layer suddenly expands and becomes fluidized. In this fluidized state, the pressure loss ΔP does not change much with respect to the change in the empty tank speed Uf. Further, when the empty tank speed Uf is increased and exceeds a certain speed Ut, the particles jump out of the particle layer. The fluidization state is maintained between the fluidization start speeds Umf and Ut. Ut is usually about 10 times Umf.In the present embodiment, the blowing speed of the blower 28 is set so that the upward empty tank speed Uf is 1 to 3 times the fluidization start speed Umf.
[0051]
When the gas blowing speed Uf for fluidization is increased in order to strengthen fluidization of the granular layer, large bubbles are generated in the granular layer, which rises in the granular layer. When the bubbles are broken in the vicinity of the upper surface of the granular layer, the surface of the granular layer is rippled, and a part of the granular particles jumps upward from the upper surface of the granular layer. Therefore, in order to suppress the undulation at the surface portion of the granular layer and the upward jump of the granular member 18, a mesh or a hole having a mesh or a hole diameter smaller than the diameter of the granular member 18 is formed on the upper surface portion of the granular layer. It is preferable that the perforated plate is put on the entire surface except for the neck of the bather 10 or is horizontally inserted into the layer of the granules 18 and fixed.
[0052]
Next, an embodiment combined with a sauna bath will be described. FIG. 9 shows a schematic structure of the embodiment. A cleaning tank 112 is placed in the sauna bath 110, and a porous plate 114 similar to the porous plate 20 is placed with a slight gap from the bottom of the cleaning tank 112. In this embodiment, the perforated plate 114 may be horizontal. A large number of particles 116 are filled on the perforated plate 114 as in the previous embodiment. There is an opening 118 in the gap between the bottom surface of the cleaning tank 112 and the porous plate 114, and water vapor or fresh water can be selectively supplied from the outside to the gap between the bottom surface of the cleaning tank 112 and the porous plate 114 by the valve 120. Yes. The valve 120 can selectively connect one of the water vapor pipe 122 and the fresh water pipe 124 to the opening 118.
[0053]
An opening 126 is provided at an intermediate height of the sauna bath 110, for example, at the height of the head of the user sitting. The opening 126 is provided for introducing fresh air from the outside and for taking out the washing water for washing the used particles 116 to the outside. For taking out the washing water, an opening therefor may be provided at a lower position, specifically, slightly above the porous plate 114. In the upper part of the sauna bath 110, there is an exhaust port 128 for discharging water vapor and air to the outside, and is connected to the exhaust blower 132 by a pipe 130. On one side of the sauna bath 110, there is an open door 134 for a user to enter and exit.
[0054]
With the valve 120 on the steam pipe 122 side, steam is injected under the perforated plate 114 through the opening 118, whereby the particles 116 on the perforated plate 114 are fluidized to a height slightly lower than the opening 126. deep. When the bather 136 enters the washing tank 112 as if entering a bathtub containing ordinary hot water, the body is washed by friction and collision between the fluidized particles 116 and the skin while bathing in water vapor. The Since fresh air enters from the opening 126, the bather 136 can inhale fresh air regardless of the fluidized particles 116.
[0055]
The water vapor injected from the opening 118 and the air entering from the opening 126 are discharged from the exhaust port 128 to the outside by the blower 132. Therefore, the atmospheric pressure in the sauna bath 110 is in a negative pressure state slightly lower than the atmospheric pressure, and air flows from the outside to the inside through the opening 126.
[0056]
In the fluidized layer of particles 116, the mixing and collision action between the particles 116 is intense, so that not only the body of the bather 136 is washed, but also when the particles 116 collide with the skin, Promotes blood circulation and helps improve health. Further, if the particles 116 are heated to emit far infrared rays, the far infrared rays are irradiated to the bather 136. This also helps improve the health of bathers 136.
[0057]
The bather 136 can go out of the sauna bath 110 by opening the door 134 at any time after the body is washed.
[0058]
After one or a predetermined number of bathers 136 use, the granules 116 are washed as follows. First, the operation of the blower 132 is stopped, and then the valve 122 on the upstream side of the opening 118 at the bottom of the cleaning tank 112 is switched from the steam pipe 122 to the fresh water pipe 124, and fresh water is put into the cleaning tank 112. The water injected into the cleaning tank 112 is stored in the cleaning tank 112 and discharged from the opening 126 when the water surface reaches the opening 126. Due to the flow of water, the granular material 116 layer is fluidized and washed. If a small amount of a cleaning agent and a disinfectant are mixed with fresh water to be injected, the particles 116 can be better cleaned and sterilized.
[0059]
Instead of using flowing water containing a cleaning agent to clean the particles 116 with flowing water, a volatile cleaning agent for dry cleaning may be mixed with hot air and supplied from the opening 118 to the inside. Thereafter, a small amount of water is applied to the particles 116 deposited on the perforated plate 114 to remove dirt and the like. Although not shown in FIG. 9, a drain outlet that discharges sweat that the bather 136 has flowed, moisture that adheres to the inner wall, and the like flows down is a drain outlet similar to the drain outlet 88 of FIG. 1. Is provided. When necessary, open the outlet.
[0060]
As in the first embodiment illustrated in FIG. 1 and the subsequent drawings, if the exhaust port 128 is provided at a height corresponding to the shoulder of the bather 136, the fluidized particles 116 are formed in the mouth and ears of the bather 136. This prevents the bather 136 from feeling the pressure of the fluidized particles 116. Of course, at this time, a filter or a screen for preventing the particles 116 from being discharged from the exhaust port 128 to the outside is installed in the exhaust port 128. The opening 126 may be installed at a higher position.
[0061]
In the present embodiment, the particles are fluidized by air, and the body is cleaned using the collision of the fluidized particles with the body, so that water is not required. That is, in the present invention, anhydrous washing can be realized and used for body washing in a precious area of water. In the above embodiment, water is used to wash the used particles, but if this is also used, the amount of water used can be reduced or zero.
[0062]
【The invention's effect】
As can be easily understood from the above description, according to the present invention, a high body washing ability can be exhibited without using water. In other words, since the particles are fluidized with a gas such as warm air, the particles can be fluidized at a higher speed than when the particles are fluidized in the liquid, and the friction and collision action on the body is high. Can demonstrate.
[0063]
Further, since it is not necessary to use a large amount of water, the apparatus can be easily installed and transported. The side wall only needs to have an airtight structure, and since the pressure is smaller than that of filling water, a simpler bathtub is sufficient. This leads to a reduction in weight and facilitates the installation and transport of the device.
[0064]
For example, when it is desired to wash the body of a care recipient such as an elderly person, it can be performed while being put on a wheelchair, so the burden on the attendant is greatly reduced.
