Description

  The present invention relates to a care bathing device used for a care recipient such as a disabled person or an elderly person to take a bath under the care of a caregiver.

  Persons who are difficult to get up or who cannot take a bath on their own (hereinafter referred to as “caregivers”), such as persons with physical disabilities, elderly people, or sick people, bathe with the help of caregivers Various types of bathing devices have been developed for this purpose. As one of such bathing devices, there is known a bathing device in which a cared person is simply moved to a bathtub from a sitting position in a wheelchair, and hot water is stored in the bathtub so that the cared person can be immersed in the hot water. It has been.

For example, in the bathing apparatus described in Japanese Patent No. 2628568, the bathtub is supported so as to swing from a state in which the upper surface opening of the bathtub is directed substantially upward to a state in which it is directed obliquely upward, and the front edge of the bathtub is It is configured to be locked in a state where it is close to the floor surface (a state where the upper surface opening is directed obliquely upward), and the cared person riding on the seat part of the wheelchair is slid into the bathtub together with the seat part. And after the cared person is accommodated in the bathtub, the cared person can take a bath in the supine position by releasing the lock, swinging the bathtub and locking it in a horizontal state, and storing hot water in the bathtub. Yes.
Patent No. 2628568

  Considering the current state of such care, caregivers are often women, but many of the work on care, especially in care that provides bathing to the care recipient as described above, There are many power tasks involving strength. For this reason, there is a strong demand to reduce such burdens on caregivers, particularly labor-intensive work.

  Even in the conventional nursing bathing apparatus as described above, a method of sliding the wheelchair seat portion into the bathtub as it is to eliminate the excessive work of lifting the cared person and moving it into the bathtub Is adopted to reduce the burden on caregivers. However, it is not easy for a powerless caregiver to swing the bathtub while the cared person is accommodated, and the bathtub after the cared person is accommodated is moved to the bathroom and hot water is supplied into the bathtub. Need to do. For this reason, it is unavoidable that the caregiver needs considerable labor when actually bathing the care recipient.

  On the other hand, for example, a bathing apparatus described in Japanese Patent Application Laid-Open No. 2000-116745 (a product such as a wheelchair bathing apparatus chair-in-bath manufactured by Aussie Giken Co., Ltd.) has a side-opening door on the side wall of the bathtub. On the other hand, a wheelchair for transferring a cared person is configured such that a seat portion and a cart portion can be separated. Then, when the wheelchair on which the cared person rides is brought close to the bathtub with the door of the bathtub opened, the carriage part remains below the bottom of the bathtub, that is, outside the bathtub, and only the seat part is covered. Enter into the bathtub with the caregiver on it. Therefore, the door can be closed thereafter, hot water can be stored in the bathtub, and the care recipient can be bathed.

  In such a bathing device, since the hot water supply device and the like are integrated, the caregiver's labor is reduced to some extent. However, since such a bathing device is premised on being installed in a nursing care facility or the like that can easily secure an installation area, it is large and occupies a large installation area. Therefore, it is very difficult to install in a general household for home nursing, for example. Therefore, there is a demand for a small bathing device that has a particularly small installation area so that it can be installed in a general household. Of course, if the installation area is small, a plurality of devices can be arranged in parallel in a nursing care facility or the like, which is advantageous.

In addition, the original purpose of the bathing device is to keep the cared person's body clean, and bathing gives the cared person a psychological positive effect such as a feeling of relaxation and coolness. The physical therapeutic effect can be expected. Therefore, it is also important to obtain a higher effect than the conventional bathing apparatus with respect to these original purposes. In addition, care recipients who use such bathing devices often cannot move on their own, or in some cases cannot speak, so there is no danger to the body during use. In addition, it is important to have strong consideration for safety, and it is important for bathers to be able to bathe in peace.

The present invention has been made in view of these several points. The first object of the present invention is to greatly reduce the work load of the caregiver, and the physique of the caregiver is relatively small. Even if it is powerless, it can be handled without difficulty,
An object of the present invention is to provide a nursing bathing apparatus with good workability.

  A second object of the present invention is to provide a bathing apparatus for care that has a small installation area and is excellent in space saving.

  A third object of the present invention is to provide a care bathing device that can achieve high safety for a cared person, that is, a bather.

  Furthermore, the third object of the present invention is to provide the cared person with sufficient satisfaction and security, thereby obtaining a high bathing effect and high for the cared person, that is, the bather. An object of the present invention is to provide a care bathing device that can achieve safety.

The bathing device for care according to the first invention made to solve the above problems,
a) a wheelchair in which the seat part on which the bather sits can be separated from the lower cart part;
b) a bathtub capable of accommodating a bather in the seated state inside,
c) A lid that closes the upper surface opening of the bathtub except for the bather's head housed in the bathtub, and has an upper opening that is pivotally supported at one end at the rear end of the bathtub. A lid that is a structure;
The bather was closed in the bathtub through the upper surface opening with the lid open, and then the lid was closed, and then the hot water was supplied into the bathtub so that the bather was immersed in the hot water. It is characterized by that.

    In the bathing apparatus for care according to the first aspect of the invention, the bather is slid into the bathtub from the trolley part while being on the seat part with the lid widely opened upward, After being accommodated in the bathtub, the lid is lowered to close a part of the upper surface opening of the bathtub. At this time, usually only the bather's head (up from the shoulder depending on the bather's physique) has jumped out of the bathtub. After that, hot water is supplied into the bathtub so that the bather can be immersed in the hot water.

  For example, if the lid has a side-opening structure, when a caregiver stands on the opposite side of the lid opening direction with the bathtub in between, the upper body must be laid across the bathtub when closing the lid. In other words, it is very difficult to perform work when the caregiver is small. In addition, since the upper body is set on the bather, psychological resistance may occur in both the caregiver and the bather. On the other hand, according to the bathing apparatus for care according to the first aspect of the present invention, since the lid is structured to open upward, the lid can be comfortably operated under the same conditions even if the caregiver stands on either the left or right side of the bathtub. Can be opened and closed. Moreover, since the caregiver can open and close the lid without getting over the upper body above the bathtub or bather, psychological resistance of the caregiver or bather does not occur. Furthermore, when the lid has an upper opening structure, the lateral size of the apparatus does not increase even when the lid is opened, which is advantageous in terms of installation space.

The bathing device for care according to the second invention made to solve the above problems,
a) a wheelchair in which the seat part on which the bather sits can be separated from the lower cart part;
b) a bathtub capable of accommodating a bather in the seated state inside,
c) a hot water storage tank installed above the bathtub and storing hot water in advance to supply hot water into the bathtub;
d) a hot water pipe connected between the hot water storage tank and the bathtub and provided with a hot water valve in the middle thereof;
e) a hot water pipe having one end connected to the hot water storage tank for discharging hot water to the outside and provided with a hot water discharge valve in the middle thereof;
And at least one of the hot water supply valve or the hot water discharge valve has a valve body that opens and closes the inlet opening of the hot water supply pipe or the hot water pipe while being immersed in hot water inside the hot water storage tank. The valve body is configured so that the valve body closes the inlet opening with water pressure by opening the inlet opening by lifting the body with a driving force by a motor and releasing the driving force.

  In one aspect of the bathing apparatus for care according to the second aspect of the invention, hot water is supplied from the hot water storage tank once stored with hot water to the bathtub through the hot water supply pipe. It has a valve element that opens and closes the inlet opening of the hot water supply pipe while immersed in hot water. For example, the valve body is pulled up by a driving force of a motor to open the inlet opening, and the driving force is released, so that the valve body closes the inlet opening with water pressure. According to such a configuration, since the hot water supply valve including the valve body can be installed inside the hot water storage tank, it is not necessary to secure a space for providing the valve outside the hot water storage tank, and space saving can be achieved. Further, instead of the hot water supply valve, the hot water discharge valve may be configured as described above, and both the hot water supply valve and the hot water discharge valve may be configured as described above. In addition, in order to shorten a waiting time of a bather, it is preferable that the hot water supply time from a hot water storage tank to a bathtub is short, and it is good to make the diameter of a hot water supply pipe thick for that purpose. In that case, when the hot water supply valve is provided outside the hot water storage tank, a particularly large space is required. However, the above configuration of the hot water supply valve is particularly effective for space saving.

Hereinafter, an embodiment of a bathing apparatus for care according to the present invention will be described with reference to the drawings.

1 to 4 are schematic side views of the main part showing the overall configuration of the bathing apparatus for nursing care. FIG. 1 shows a state when the bathtub is stored, and FIG. 2 shows a bather on a wheelchair in the bathtub. Fig. 3 shows the state when the chair is placed in a wheelchair from the inside of the bathtub or vice versa (hereinafter, this state is referred to as "setting state"). FIG. 4 shows a state in which the lid of the bathtub is opened in FIG. FIG. 5 is an external front view (A) and an external side view (B) of a dedicated wheelchair that is a part of the nursing bathing apparatus.

The care bathing apparatus is roughly divided into a main body device 1 provided with a bathtub 12 accommodated in a bathtub in a posture in which a bather who is a caregiver is seated, and a bather is accommodated in the bathtub 12 or its On the contrary, it is composed of a dedicated wheelchair 2 used for exiting from the bathtub.

In the main body device 1, a support column 10 is erected at the rearmost part, and a hot water storage tank 11 having a capacity of about 200 L at the maximum is provided above the support column 10. The height to the upper surface of the hot water tank 11,
That is, the total height of the main unit 1 is the height of the ceiling of a general house in Japan 2400
It is limited to about 2300mm so that it is less than or equal to mm, and so-called home care placement is being considered. Below this hot water storage tank 11, a shallow bottom bathtub 12 formed so that the front wall and the rear wall are inclined toward the center of the bottom surface is a pair of left and right bathtub rollers provided slightly forward from the bottom. 13 and a shaft support portion 14 provided to project from the rear wall. As will be described later, the shaft support portion 14 moves up and down by the operation of the motor, thereby pushing down or pulling up the rear side of the bathtub 12. Below the column 10, an inclined guide portion 15 that is inclined upward toward the rear is provided.
Moves up and down to pull up or push down the rear part of the bathtub 12.
Is configured to climb or descend along the inclined guide portion 15.

The upper surface of the bathtub 12 facing upward in the standard bathing state as shown in FIG.
The upper surface opening 12a) has an opening 12 through which the bather on the rear side projects the head.
The lid 16 can be closed except for b. As shown in FIG. 4, the lid 16 is swingably provided by an arm 18 having one end pivotally supported at the rear end of both side walls of the bathtub 12, and the arm 18 is directed upward by a gas spring 19 with an appropriate force. Is being energized. As shown in FIG. 2, the lid 16 maintains a closed state by a lock mechanism (not shown) when in close contact with the upper surface opening 12 a of the bathtub 12, but the lock is released by a human hand and an upward force is applied. Then, the gas spring 19 is slowly opened by the urging force of the gas spring 19, and finally it is completely opened as shown in FIG. That is, in the state of FIG. 4, the upper surface opening 12a of the bathtub 12 is directed forward, and the bather P is moved into the bathtub 12 from the front as described later, or conversely, the bather P is removed from the bathtub 12. Can be moved forward.

As a method of opening and closing the lid body 16, in addition to the upward opening as in the present embodiment, a lateral opening with a hinge or the like is also conceivable. However, in the case of side-opening, if a caregiver stands on the side opposite to the opening direction of the lid, it is necessary to cross the top of the bathtub and put a hand on the lid when closing the lid. It becomes a very difficult task for the person. Further, in the case of lateral opening, the lateral width size of the main body device with the lid opened is large, which is disadvantageous in terms of installation space when it is desired to use a plurality of main body devices side by side. On the other hand, in the lid opening method with the upper opening, the lid 16 can be opened and closed without difficulty even when the caregiver stands on either the left or right side of the bathtub 12, and the maximum width size of the main body device 1 is reduced. can do.

FIG. 6 is a perspective view of a main part around the shaft support 14 for tilting the bathtub 12 of the main body device 1. A horizontal shaft body 20 passes through the support piece portion 12c projecting from the rear wall of the bathtub 12 so as to be rotatable, and both ends of the shaft body 20 are fixed to the movable body 21. The movable body 21 includes a ball screw nut 22 that meshes with a screw groove of a screw shaft 23 that is vertically extended, and when the screw shaft 23 is rotationally driven by a motor 24,
The ball housed in the ball screw nut 22 rolls spirally along the thread groove of the screw shaft 23, whereby the movable body 21 moves up or down along the screw shaft 23. As a result, the rear part of the bathtub 12 is pulled up or pushed down through the shaft body 20 and the support piece 12c.

In FIG. 6, a magnet 25 is attached to one side surface of the movable body 21, and four reed switches 26 are installed in the vertical direction on the column 10 adjacent thereto, so that the movable body 21 moves up and down. These reed switches 2 according to their positions when
6 is configured to conduct appropriately, the operation of which will be described in detail later.

As shown in FIG. 5, the wheelchair 2 is slidable rearwardly on a carriage unit 210 including a pair of left and right front wheels 213 and a pair of left and right rear wheels 212 having a large diameter. And a seat portion 220 on which the bather sits. As will be described later, the seat portion 220 is provided with a backrest column 223 at the rear ends of a pair of left and right lateral base portions 221 provided with a plurality of rollers therein, and an armrest portion 222 between the backrest column 223 and the base portion 221. Is provided. In addition, the horizontal base 221 is provided with a footrest for a bather to put his sole on. A mesh-shaped seating surface 225 is stretched between the pair of horizontal base portions 221, and a mesh-shaped backrest 226 is stretched inside the backrest column 223 with an appropriate tension. In this way, seat 2
Since the water and air freely pass through the mesh 25 and the backrest 226, the water and air easily hit the body surface of the bather in contact with the seating surface 225 and the backrest 226. In addition, the backrest column 223 is indexed with a three-level water level mark 227 for use as a guide when the caregiver sets the hot water supply amount.

Next, in addition to FIG. 5, the slide mechanism of the seat part 220 of the wheelchair 2 and the operation when transferring the bather into the bathtub 12 or vice versa are shown in FIG.
Description will be given with reference to FIG.

On the pair of left and right support columns 211 of the carriage unit 210 of the wheelchair 2, an elongated substantially U-shaped guide rail 214 that is open at the rear is fixed. The horizontal base portion 221 of the seat portion 220 includes a disc portion 228 a that sandwiches the guide rail 214 from both sides, and a roller 228 for a carriage portion that includes a sliding portion 228 b that is in contact with the guide rail 214 between the upper and lower sides.
However, four are provided at appropriate intervals in the front-rear direction, and further, a bathtub roller 229 is separately provided inside the three cart roller 228. As the carriage roller 228 rolls back and forth along the guide rail 214, the seat 220 slides back and forth on the carriage 210. At this time, the bathtub roller 229 does not function. On the other hand, the inner wall surface of the bathtub 12 is formed with a bathtub inner rail 12d that is substantially horizontal in the setting state.
In a state where 0 is in the bathtub 12, the roller 220 for the bathtub 229 travels on the rail 12 d in the bathtub, so that the seat 220 slides. At this time, the trolley roller 228 floats in the bathtub 12 and is not functioning.

In this way, the carriage roller 228 is dedicated to running on the carriage 210, while the bathtub roller 229 is dedicated to running in the bathtub 12, so that the material of each roller is the material of the guide rail 214 and the bathtub rail 12d. Can be selected as appropriate to suit. As a result, frictional noise during traveling can be reduced, and wear on the traveling surface can be reduced, thereby achieving high reliability.

As shown in FIG. 8, the bather P sitting on the seat 220 of the wheelchair 2 is shown in FIG.
As shown in FIG. 2, when the liquid is transferred into the bathtub 12 in which the lid body 16 is opened, the following is performed.

First, as shown in FIG. 8, the wheelchair 2 is approached rearward with respect to the bathtub 12, and the bowl-shaped carriage side latching piece 21 provided behind the carriage section 210 of the wheelchair 2 is provided.
5 is engaged with the stopper 176 of the main body device 1, so that the carriage unit 210 is temporarily fixed to the main body device 1. From this state, when the caregiver pushes the seat 220 or the bather P backward, that is, in the direction of the bathtub 12, the roller 228 for the carriage unit
Rolls along the guide rail 214, and the seat portion 220 slides backward with the bather P on it.

As shown in FIG. 10 (A), the last cart roller 228 is disengaged from the guide rail 214 as shown in FIG. 10A. At that time, the other three cart rollers 228 are on the guide rail 214. Therefore, the seat part 220 maintains a substantially horizontal state. FIG.
As shown in (B), the second carriage roller 228 from the tail is the guide rail 2.
Before detaching 14, the last bathtub roller 229 rides on the bathtub inner rail 12d. Therefore, for a while when the seat part 220 is further moved backward from this state, the rear side of the seat part 220 is supported by the bathtub roller 229 and the front side is supported by the carriage part roller 228 (FIG. 11). (See (A)).

As shown in FIG. 11 (B), the head carriage roller 228 is guided by the guide rail 214.
The second bath roller 229 from the top rides on the bath inner rail 12d. Therefore, thereafter, the bathtub roller 229 moves on the bathtub inner rail 12d, so that the seat portion 220 is accommodated in the bathtub 12 while the bather P is placed thereon.
And when the seat part 220 is completely accommodated in the bathtub 12, only the trolley | bogie part 210 is left ahead of the bathtub 12, as shown in FIG. In addition, when the seat part 220 is returned from the bathtub 12 onto the carriage part 210 of the wheelchair 2 after the bathing is completed, a procedure completely opposite to the above description may be performed.

As shown in FIG. 9, the rear end 214a of the lower rail of the guide rail 214 has an upper surface inclined downward toward the tip. Therefore, in particular, the seat part 220
When moving from the bathtub 12 to the carriage unit 210, the carriage unit roller 228 smoothly lands on the front end of the guide rail 214. Therefore, a large impact is not given to the bather sitting on the seat part 220.

Now, in order to fix the carriage part 210 of the wheelchair 2 to the main body apparatus 1 as mentioned above,
The main body device 1 is provided with a stopper 176 for fixing. If the stopper 12 is projected forward in the state where the bathtub 12 is housed, there is a possibility that the main body device 1 may be tripped by an obstacle. Therefore, the nursing bathing apparatus of the present embodiment is provided with a stopper telescopic mechanism 17 that moves the stopper back and forth in the front-rear direction as the bathtub 12 tilts. FIG. 12 is a side view showing the configuration of the stopper expansion / contraction mechanism 17. That is, one end of the first member 171 is pivotally supported on both sides of the inclined guide portion 15, and one end of the second member 172 is pivotally supported on the other end, and the other end contacts the floor surface and rolls. A moving roller 173 is provided.

Torsion coil springs 174 and 175 are provided at the connecting portion between the inclined guide portion 15 and the first member 171 and the connecting portion between the first member 171 and the second member 172, respectively, and no force is applied from the outside. At this time, the first member 17 is arranged so that the roller 173 approaches the inclined guide portion 15 by the urging force of the two torsion coil springs 174 and 175.
1 and the 2nd member 172 stand up together (refer to Drawing 12 (A)). As a result, these members move backward and do not get in the way. When the bathtub 12 is tilted from the stored state to the setting state, the bathtub roller 13 moves down the tilt guide portion 15 as described above. Since the weight of the bathtub 12 is applied to the bathtub roller 13, the first member 171 is pushed by the bathtub roller 13 and falls down, and the roller 173 rolls forward and the second member 172 also falls, and both these members 171 fall. , 172 extends while spreading in a letter C shape as a whole. Thereby, the first and second members 171 and 172 are finally obtained.
As shown in FIG. 12 (B), it extends substantially in a straight line, and the stopper 176 advances forward and points upward.

FIG. 13 is an overall side view (A) and a front view (B) of the main device 1 in the bathtub storage state.
). As shown in FIG. 13 (B), the inclined surface 3 under the hot water tank 11 of the main unit 1.
1, an operation panel 30 for performing various operations in the main body device 1 is provided on the left side when viewed from the front.

FIG. 14 is an enlarged view of the operation panel 30. The operation panel 30 has a power switch 3
01, setting operation key 302, storage operation key 303, forced end key 304, hot water tank hot water amount confirmation display 305, hot water tank hot water temperature setting key 306 with hot water tank hot water temperature display, hot water temperature confirmation key 307, start Key 308, bathing time setting key 309 with bathing time indicator, bathtub angle setting key 310 with bath angle selection indicator,
(In bathtub) Hot water setting key 311 with hot water selection display, hot water addition instruction key 312,
Bubble generation instruction key 313, bathtub drain instruction key 314, hot water tank drain instruction key 315
Various operation keys such as a bathing agent charging instruction key 316, a use-up instruction key 317, a body shampoo charging instruction key 318, and the like are provided.

As shown in FIG. 13B, in the state where the bathtub 12 is stored, the operation panel 30 is provided.
Since a part of the right side is hidden behind the bathtub 12, the display is difficult to see but difficult to operate, although it cannot be operated. Therefore, in the nursing bathing apparatus of the present embodiment, keys that need to be operated in the bathtub storage state in the operation panel 30, the power switch 301, the setting operation key 302, the storage operation key 303, the forced end key 304, the hot water storage The bath water amount confirmation display 305 and the hot water bath hot water temperature setting key 306 are collected on the left side. Therefore, operability is not impaired. A shower head 32 for jetting hot water is provided on the left side surface of the main unit 1, and a shower valve 33 and a shower hot water temperature adjusting knob 34 are provided below the operation panel 30.

Subsequently, the structure for performing the hot water supply to the bathtub and the drainage from a bathtub in this apparatus is demonstrated.

FIG. 15 is a piping configuration diagram for water supply / drainage in the nursing bathing apparatus, FIG. 16 is a configuration diagram mainly showing a hot water supply route, and FIGS. 17 and 18 are side views showing the drainage route.

In FIG. 15, a hot water pipe 40 leading to an external water heater and a water pipe 41 leading to a water tap.
Is connected to two mixing valves (thermomixing valves) 42, 43, one of the second
Hot water that is appropriately mixed by the mixing valve 43 and whose hot water temperature is adjusted is discharged from the shower head 32 through the shower pipe 44. The hot water, which has been appropriately mixed by the other first mixing valve 42 and adjusted in hot water temperature, is supplied into the hot water storage tank 11 through a hot water storage valve 45 that is an electromagnetic valve, and a bypass pipe provided with a bypass valve 47 in the middle. A hot water supply pipe 48 is connected via 46.

A hot water supply hole connected to a hot water supply pipe 48 and a hot water discharge hole connected to a hot water discharge pipe 49 are provided at the inner bottom of the hot water storage tank 11, and the hot water supply valve 50 opens and closes according to the operation of the torque motors 51 and 53, respectively. A hot water discharge valve 52 is provided. As shown in FIG.
0 is a pulley 5 corresponding to the operation of the valve body 501 with the heel face down and the torque motor 51.
A chain 502 pulled by 03 and a communication pipe 504 communicating with the atmosphere below the valve body 501 are provided.

For example, when the torque motor 51 operates and the pulley 503 rotates to pull the chain 502, the valve body 501 is pulled up against the water pressure. At this time, since air is sent to the hot water supply pipe 48 through the communication pipe 504, the inside of the hot water supply pipe 48 does not become negative pressure, the valve body 501 is lifted smoothly, and hot water flows from the hot water storage tank 11 into the hot water supply pipe 48. On the other hand, when the operation of the torque motor 51 is stopped and the chain 502 is loosened, the valve body 501 is closed by the water pressure. At this time, air escapes from the hot water supply pipe 48 through the communication pipe 504. Close to. The operation of the hot water discharge valve 52 is the same. Thus, since the hot water supply valve 50 and the hot water discharge valve 52 are disposed inside the hot water storage tank 11, there are no members related to these valves outside the hot water storage tank 11, and space saving is achieved.

In the middle of the hot water supply pipe 48, a liquid charging device for automatically charging a body shampoo and bathing agent is provided. The liquid charging device includes, for example, a bathing agent storage bottle 55 that is a liquid, and a hot water supply pipe 48 that sucks the liquid from the storage bottle 55.
It comprises a pump 56 that feeds inward. As the pump 56, a so-called tube pump is used in which the roller rotates and crushes the tube as the motor rotates, and the liquid is sent in the same direction as the rotation of the roller while squeezing the tube. In this device, the body shampoo and bathing agent liquid charging devices are provided separately, but using a clutch mechanism etc., one pump sucks liquid from the body shampoo bottle and bathing agent bottle in a switching manner. -It is good also as a structure which sends. Thus, hot water supply pipe 4
The hot water supplied through 8 is discharged into the bathtub 12 from the hot water supply port 12e.

The water accumulated in the bathtub 12 is discharged to the outside through a drain port 12 f provided on the bottom of the front part of the bathtub 12. The drainage port 12f is connected to an external drainage groove through a bellows-like drainage pipe 59 that can be expanded and contracted. When the drainage valve 58 provided in the vicinity of the drainage port 12f is opened, the drainage from the bathtub 12 is drained. Water flows into the pipe 59 and is discharged to the outside. As shown in FIGS. 1 and 3, the drain port 12 f is not located at the lowest part of the bathtub 12 in the bathtub storage state or the standard bathing state, but is the lowest part of the bathtub 12 only in the setting state. Therefore, in order to completely discharge water from the bathtub 12, it is necessary to open the drain valve 58 in the setting state.

Further, if hot water overflows from the bathtub 12 during hot water supply or bathing to the bathtub 12, the floor surface around the main body device 1 is wetted. Accordingly, in order to prevent the overflow of hot water from the bathtub 12, as shown in FIG. 18, in addition to providing two overflow outlets 12g and 12h on the inner wall of the bathtub 12, one overflow outlet is also provided on the lid. 16a is provided. Two overflow outlets 12g and 12h of the bathtub 12 are overflow pipes 12 formed inside the side wall of the bathtub 12.
When the water level rises to a position higher than the overflow outlets 12g and 12h, the hot water flowing into the overflow outlets 12g and 12h is discharged to the outside through the overflow pipe 12j and the drainage pipe 59. Discharged. On the other hand, the overflow outlet 16a provided in the lid body 16 has an overflow pipe 16b formed inside the lid body 16 and the side of the bathtub 12 connected to the overflow pipe 16b when the lid body 16 is closed.

FIG. 19 is an overall configuration diagram of the electrical system of the nursing bath apparatus according to the present embodiment. A microcomputer (hereinafter abbreviated as “microcomputer”) 80 is placed at the center of control, and key input signals are sent from the operation keys 30a provided on the operation panel 30 to the hot water tank water level sensor 6.
7 and the water level detection signal from the bathtub water level sensor 68, the temperature detection signal from the mixing valve temperature sensor 63, the hot water tank temperature sensor 64, the hot water pipe temperature sensor 65 and the temperature sensor 66 in the bathtub, and the seat height detection signal from the seat height detection sensor 70. The bathtub position detection switch 26
, Detection signals corresponding to the position of the bathtub 12 are respectively input to the microcomputer 80.
As is well known, the microcomputer 80 has a built-in RAM and ROM, and a control program relating to the operation described later is stored in advance in the ROM. In the process of executing the control program while receiving various signals as described above, the bathtub tilting motor 24, hot water supply torque motor 51, hot water discharge torque motor 53, air pump 60, hot water storage tank 11 are provided via the load drive unit 81. The hot water storage valve 45 for controlling the hot water supply to the hot water tank, the first mixing valve 42 for controlling the temperature of the hot water supplied to the hot water storage tank 11, the bypass valve 47, the second mixing valve 43 for controlling the temperature of hot water for shower, and the bathtub 12 Drain valve 5 for discharging stored hot water
8. A bath agent charging pump 56a for mixing bathing agent into hot water supplied to the bathtub 12 and a body shampoo charging pump 56b for mixing liquid soap for bath into hot water supplied to the bathtub 12 are driven.

FIG. 20 is a circuit configuration diagram showing the relationship between the microcomputer 80 and the plurality of bathtub position detection switches 26. Each of the four bathtub position detection switches 26 shown in FIG. 20 is a reed switch depicted in FIG.

Further, in this bathing apparatus for nursing care, when the bathtub 12 is tilted between the housed state and the setting state, even if the microcomputer 80 runs away due to external noise or the like, an abnormal operation occurs and the caregiver It is considered so as not to threaten the safety of people around. FIG. 21 is a circuit configuration diagram of a main part related to driving of the motor 24.

The motor 24 is connected to a power source 82 via an electromagnetic relay 84 and a polarity switching switch 83. The polarity switching switch 83 is switched by a control signal from the microcomputer 80, and changes the rotation direction of the motor 24, whereby the bathtub 12 (movable body 2
Switch between ascending or descending of 1). The coil of the electromagnetic relay 84 includes a current supply circuit including a setting operation key 302 and a third photocoupler TR3, a current supply circuit including a storage operation key 303 and a second photocoupler TR2, a switch 85 and a first
A current supply circuit including the photocoupler TR1 is connected in parallel. When a current is supplied from any of the current supply circuits, the electromagnetic relay 84 is turned on and a drive current is supplied to the motor 24. Yes.

22 is a diagram showing the configuration of the switch 85 in FIG. 21, (A) is a side view of the entire main unit, (B) is a front view with the bathtub removed, and (C) is in (B). It is an enlarged view of the principal part. As shown in FIG. 22C, the guide wall 8 provided with a step 86a is provided on the support column 10 positioned on one side surface of the movable body 21 that moves up and down along the screw shaft 23.
6 is formed, and the movable piece of the switch 85 provided on the side surface of the movable body 21 is
When it is above the step 86a, it receives no force from the guide wall 86, and when it is below the step 86a, it receives a pressing force from the guide wall 86. For this reason, the switch 85 is used when the movable body 21 is positioned above the vicinity of the step 86a (H1 in FIG. 22A).
And is closed when the movable body 21 is located below the vicinity of the step 86a (when it is in the range H2 in FIG. 22A).

The opening / closing of the switch 85 can be detected by a signal at the input port Pi1 of the microcomputer 80. Since the output transistor of the first photocoupler TR1 is conducting when the switch 85 is closed, regardless of the operation of the other two current supply circuits,
The opening / closing operation of the electromagnetic relay 84 can be controlled by a signal output to the output port Po1 of the microcomputer 80. That is, the operation of the motor 24, that is, the tilting operation of the bathtub 12 can be performed by the spontaneous control of the microcomputer 80.

On the other hand, since the output transistor of the first photocoupler TR1 is cut off when the movable body 21 is in the range of H1 and the switch 85 is opened, this current supply circuit contributes to the opening / closing control of the electromagnetic relay 84. I don't get it. On the other hand, the output transistors of the photocouplers TR2 and TR3 included in the other two current supply circuits are respectively
Since the conducting operation is conducted only when the storing operation key 303 and the setting operation key 302 are pressed, the storing operation key 303 is provided even if the output of the output ports Po2 and Po3 of the microcomputer 80 is a potential for supplying a current to the coil. Alternatively, the electromagnetic relay 84 is not turned on unless the setting operation key 302 is pressed. Therefore, the movable body 21 is H
When it is in the range of 1, it is necessary to press the storage operation key 303 or the setting operation key 302 by a human hand to tilt the bathtub 12, and an abnormal operation due to a malfunction of the microcomputer 80 has occurred. Even in cases, the loss of safety is reduced.

Since the motor 24 is operated only while the storage operation key 303 or the setting operation key 302 is being pressed, if the caregiver feels danger during the tilting operation of the bathtub 12 and releases the key, the tilting of the bathtub 12 is immediately Stop. Therefore, high safety can be ensured also in this respect.

Moreover, when the movable body 21 is in the range of H2, the tilt of the bathtub 12 is controlled by the microcomputer 80. Normally, the maximum tilt position of the bathtub 12 is the standard bathing state as shown in FIG. Although the upper edge of the opening 12b is a substantially horizontal position, even when a microcomputer 80 runs away or a mechanical part such as a ball screw nut is broken, it does not tilt further from the above position of the bathtub 12. A mechanical stopper 27 is provided at the lower end of the screw shaft 23 so as to abut against the movable body 21 and prohibit further lowering.

In addition, in this bathing apparatus for nursing care, an appropriate amount of hot water is stored in the bathtub 12, and bathing is performed so that the bather is immersed therein. For example, when the bather is intended to be immersed in hot water to the level of the shoulder rib of the bather The amount of hot water required varies depending on the physique of the bather, especially the sitting height. Although it is possible to set the amount of hot water as will be described later in order to cope with such a difference in physique of bathers, when a person whose sitting height is extremely low is accommodated in the bathtub 12, the face can be immersed in hot water. There is sex. Therefore, in this bathing device, the height of the person to be used is limited to, for example, about 140 cm or more, but in order to cope with individual differences in physique due to differences in sitting height, etc., and to further improve safety, Detection sensor 7
0 is provided.

FIG. 23 is a schematic view of the waist portion showing the configuration of the sitting height detection sensor 70, (A) is a side view, and (B) is a front view. An infrared light emitting unit 70a and an infrared light receiving unit 70b are arranged on both sides of the bather P or P ′ contained in the bathtub 12 so as to sandwich the head. The installation heights of the light emitting unit 70a and the light receiving unit 70b are those having a physique suitable as a bather (for example, FIG. 23) in the standard bathing state as shown in FIG.
If P ′), the height is set such that the irradiated infrared light is blocked by the head. Therefore, a person who has an ineligible physique as a bather (for example, P in FIG.
) Tries to bathe, the head does not block the irradiated infrared light, and the light receiving unit 70b receives the infrared light. Can be automatically identified.

Next, operation | movement of the bathing apparatus for care of the present Example which has the said structure is demonstrated one by one.

First, a series of procedures when the caregiver bathes the bather using the care bathing apparatus will be described with reference to the flowcharts shown in FIGS. As shown in FIG. 1, the bathtub 12 of the main device 1 is assumed to be in a predetermined storage position as an initial state.

First, the caregiver turns on the power by pressing the power switch 301 on the operation panel 30 of the main device 1 (step S1). Then, electric power is supplied to the electric circuit including the microcomputer 80, and the microcomputer 80 starts a predetermined control program and executes an initial setting process. As a result, the setting operation key 302 can be received.
When the caregiver presses the operation key 302, the bathtub tilting motor 24 is driven via the load driving unit 81 only while the operation key 302 is pressed. Thereby, the movable body 21 descends and the bathtub 12 is moved.
Begins to tilt so that the upper surface opening 12a faces upward. When the bathtub 12 reaches a predetermined setting position, the motor 24 stops and the setting is completed (step S2).

Next, the caregiver sets an appropriate hot water temperature with the hot water tank hot water temperature setting key 306 (step S3). In response to this setting, hot water storage in the hot water storage tank 11 is started by opening the hot water storage valve 45 while the mixing ratio of hot water and water is adjusted by the first mixing valve 42 (step S4). When full water is detected by the detection signal from the hot water tank water level sensor 67, the hot water valve 45 is closed and hot water storage in the hot water tank 11 is stopped (steps S5 and S6). Upon completion of hot water storage, various operation keys can be accepted (step S7), and the caregiver can take a half-body bathing time, a whole body bathing time, a whole body bathing by using a bathing time setting key 309, a bathtub angle setting key 310, and a hot water volume setting key 311. Bathtub angle,
In addition to setting the appropriate amount of the whole-body bath water, if necessary, use-out instruction key 3
17. By operating the bathing agent charging instruction key 316, the body shampoo charging instruction key 318, and the bubble generation instruction key 313, instructions such as exhausting operation, automatic charging of the bathing agent, automatic charging of the body shampoo, and generation of bubbles are given. (Step S8)
.

After making all these settings, the caregiver accommodates the bather P in the bathtub 12,
The lid body 16 is closed (step S9). That is, for example, the bather P lying on the bed is seated on the seat part 220 of the wheelchair 2, the wheelchair 2 is brought close to the bathtub 12 from the front of the bathtub 12, and the carriage part 210 is temporarily fixed to the main body device 1. In this state, the seat part 220 of the wheelchair 2 is slid rearward with the bather P on it and moved into the bathtub 12. After the bather P is completely accommodated in the bathtub 12, if the lid 16 is lowered and locked, the bathtub 12 is sealed with the lid 16 with the bather P protruding from the opening 12b. The

The steps up to this point are preparation work for bathing, and there are many work involving caregivers, but after that, basically the bathing operation is performed by the automatic operation of the care bathing apparatus. In order to start this driving, the caregiver presses the start key 308 (step S10). In response to this key operation, the microcomputer 80 first checks whether or not there is an instruction for a single-use operation (step S11). The use-up operation is basically based on the premise that the other person does not take a bath after the bathing end of the bather.
The hot water of 1 will be used up.

If there is an instruction for the exhaustion operation, it is then determined whether or not the whole body bathing time is 0 minutes (step S12). In the case of a single-use operation and when the whole body bathing time is zero, that is, only half-body bathing is performed, it is not necessary to replenish hot water in the hot water tank 11 after hot water is supplied to the bathtub 12 immediately after this. Hot water storage is prohibited (step S13). On the other hand, if it is not a full-time operation, or even if it is a full-time operation, if the whole body bathing time is not zero, the process proceeds directly to step S14 to drive the hot water supply torque motor 51 and open the hot water supply valve 50. Thus, hot water supply from the hot water tank 11 to the bathtub 12 is started. When the hot water prohibition in step S13 is not set, when the water level in the hot water tank 11 is lowered by hot water supply to the bathtub 12, new hot water is supplied to the hot water tank 11 correspondingly. Will be explained later.

After the start of hot water supply, it is determined whether or not there is an instruction to add a bathing agent (step S15). If there is an instruction to add a bathing agent, the bathing agent charging pump 56a is operated (step S16).
). Also, it is determined whether or not there is an instruction for body shampooing (step S17),
Body shampoo injection pump 5 when instructed to supply body shampoo
6b is operated (step S18). When the bathing agent charging pump 56a and the body shampoo charging pump 56b are operated, the bathing agent and body shampoo previously stored in the container are sucked up from the container and mixed in the hot water supply pipe 48. Therefore, when hot water is discharged into the bathtub 12, bath additives and body shampoo are mixed in the hot water, and such hot water accumulates in the bathtub 12 and the water level gradually rises.

The microcomputer 80 monitors the water level in the bathtub 12 by the water level sensor 68 in the bathtub, and when it is determined that the water level has reached a predetermined half-body bathing water level (Yes in step S19), the hot water valve 50 is closed. Hot water supply is stopped (step S20).
The water level at this time is such a level that the bottom is immersed from the waist of the bather P accommodated in the bathtub 12. Thereafter, the subtraction of the half-body bathing time set by the caregiver is started first, and the subtraction is continued until the remaining time becomes zero (steps S21 and S22). When the half-body bathing time is zero · BR> no, the drain valve 58 is opened and the hot water in the bathtub 12 is discharged (step S23). As shown in FIG. 17, the bathtub 12 is in the setting state and the drain port 12 f is at the lowest part in the bathtub 12, so that all of the hot water in the bathtub 12 is discharged.

Next, the microcomputer 80 drives the bathtub tilting motor 24 again via the load driving unit 81 to tilt the bathtub 12 further (step S24). And if it reaches the bathtub angle initially set by the caregiver (strictly, the bathtub angle corresponding to the four-step inclination) (Yes in step S25), the motor 24 is stopped to tilt the bathtub 12. Stop (step S26). After the stop, it is determined whether or not the inclination of the bathtub 12 is maximum (in this embodiment, the inclination is the maximum in the standard bathing state shown in FIG. 3) (step S27), and the inclination is maximum. Is the sitting height detection sensor 7
Based on the detection signal of 0, it is determined whether or not the physique of the bather P, specifically, the sitting height is suitable for the present apparatus (step S28).

Since this apparatus automatically supplies hot water, even if the hot water stored in the bathtub 12 is at the lowest level, if the bather's sitting height is very low and the bathtub 12 is tilted to the maximum, There is a risk that the part will be immersed in hot water. Therefore, the suitability of the bather's physique is checked in step S28, and if it is deemed unqualified, an error notification is made by ringing the buzzer 30c (step S29), and this is indicated to the caregiver. Inform. This makes the safety very high.

When the physique of the bather P is qualified, next, it is checked whether or not there is an instruction for single use driving (step S30). When the exhaustion operation is instructed, it is not necessary to replenish hot water in the hot water tank 11 after hot water supply to the bathtub 12 immediately after this, so hot water storage in the hot water tank 11 is prohibited (step S31). On the other hand, when it is not the exhaustion operation, it progresses directly to step S32, the hot water supply torque motor 51 is driven, and the hot water supply valve 50 is opened, and the hot water supply from the hot water storage tank 11 to the bathtub 12 is started. When the prohibition of hot water storage in step S31 is not set, when the water level in the hot water storage tank 11 is lowered by hot water supply to the bathtub 12, new hot water is supplied to the hot water storage tank 11 correspondingly.

Subsequently, if the bathing agent or body shampoo is instructed by the processing in steps S33 to S36 similar to steps S15 to S18, these are mixed into hot water to be supplied. And the microcomputer 80 monitors the water level in the bathtub 12 by the water level sensor 38 in a bathtub, and when it determines with the water level having reached the whole body bath water level (it is Yes at step S37), the hot water supply valve 50 will be closed and hot water supply will be stopped. (Step S
38). Then, subtraction of the whole body bathing time initially set by the caregiver is started, and the subtraction is continued until the remaining time becomes zero (steps S39 and S40).
. When the whole body bathing time becomes zero, the drain valve 58 is opened to start discharging hot water in the bathtub 12, and the bathtub tilting motor 24 is driven to return the bathtub 12 to the setting position (step S41).

When the bathtub 12 returns to the setting position (Yes in step S42), the motor 2
4 is stopped and the tilting of the bathtub 12 is stopped (step S43). As described above, when the bathtub 12 is in the whole body bathing position, the drain outlet 12f of the bathtub 12 is not necessarily at the lowest position, but is always at the lowest position when the bathtub 12 returns to the setting position. . Therefore, after a lapse of time after the bathtub 12 returns to the setting position, all the hot water in the bathtub 12 is discharged. Then buzzer 30
An end of bathing notification is given to the caregiver by ringing c (step S44). Thus, even when the caregiver is away, the fact can be recognized immediately at the end of bathing, so that the bather P is not left in a state after the end of bathing.

Then, the caregiver is the lid 1 in the reverse procedure to the operation of accommodating the bather P in the bathtub 12.
6 is opened, and the seat part 220 on which the bather P is placed is slid from the bathtub 12 onto the carriage part 210 of the wheelchair 2. And the temporary fixing of the cart part 210 of the wheelchair 2 is cancelled | released, and the wheelchair 2 is made to detach | leave from the main body apparatus 1 (step S45). Continuing,
When bathing another bather, it is only necessary to return to step S8 (when setting conditions are changed) or step S9. However, when bathing is not performed, the caregiver moves the bathtub 12 to the storage position. To return, the storage operation key 303 is pressed. As described above, the bathtub tilting motor 24 is driven only while the storage operation key 303 is pressed, and the shaft support 1
The rear part of the bathtub 12 is pulled up by 4 and the bathtub 12 returns to the storage position (step S46). When the storage position is reached, the motor 24 stops, and even if the storage operation key 303 is pressed, it does not operate any more. Finally, the caregiver presses the power switch 301 to cut off the power supply of the main body device 1 (step S47), and all the work related to bathing is completed.

[Temperature control during hot water supply by bypass pipe]
Usually, the hot water stored in the hot water tank 11 is supplied into the bathtub 12, but the temperature of the hot water being supplied into the bathtub 12 is lower than expected and the temperature of the hot water to be supplied is to be increased. In addition, it is possible to supply hot water via the bypass pipe 46 without passing through the hot water storage tank 11. FIG. 28 is a flowchart of hot water temperature control during hot water supply using such a bypass pipe.

First, the microcomputer 80 determines whether or not hot water is being supplied from the hot water storage tank 11 to the bathtub 12 (step S171). If hot water is being supplied, it is next determined whether or not it is immediately before reaching the set water level. (Step S172). If hot water is supplied into the bathtub 12 if it is not immediately before reaching the set water level even during hot water supply, the hot water temperature in the bathtub 12 may become too high. Quit without doing. If it is just before the set water level is reached, it is determined whether or not the hot water temperature in the bathtub 12 is close to the set hot water temperature using a temperature detection signal from the bathtub internal temperature sensor 66 (step S1).
73). When the hot water temperature in the bathtub 12 is close to the set hot water temperature, if hot water is supplied from the bypass pipe 46, the hot water temperature in the bathtub 12 may become too high. When the set water level is reached (Yes in step S174), the hot water supply valve 50 is closed (step S175).

If the hot water temperature in the bathtub 12 is not close to the set hot water temperature in step S173, that is, if it is lower than the set hot water temperature to some extent, the hot water temperature is appropriately adjusted by the first mixing valve 42 (step S176). The hot water supply valve 50 is closed and the bypass valve 47 is opened (step S177). Thereby, the inflow of hot water from the hot water storage tank 11 to the hot water supply pipe 48 is stopped, and supply of hot water via the bypass pipe 46 is started instead. Since the hot water at this time does not pass through the hot water storage tank 11, the hot water temperature adjusted by the first mixing valve 42 is maintained almost as it is, and the set temperature is set to be, for example, 1 to several degrees higher than the set hot water temperature. By keeping it, hot water having a slightly higher temperature can be supplied into the bathtub 12. When the water level in the bathtub 12 reaches the set water level (step S17).
8), the bypass valve 47 is closed and hot water supply is stopped (step S179).
