Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub control device.

[0002]

2. Description of the Related Art Conventionally, a bathtub (hereinafter referred to as "first conventional technology") described in Japanese Utility Model Publication No. 2-19099 is known. The first conventional bathtub has a structure in which the bottom of the bathtub is divided into a stool bottom that is continuous with the backrest surface and a footrest bottom that is one step lower than the stool bottom, and a neck rest is formed on the upper edge of the backrest surface. In addition, the bather was able to take a bath in a relaxed posture by sitting on a stool bottom, with the upper body stretched along the backrest and leaning his neck on the neck rest.

In addition, a bathtub for the elderly and physically handicapped (hereinafter referred to as the second prior art) described in Japanese Utility Model Laid-Open No. 61-115540 is also known. The bathtub according to the second conventional technique includes a main bath portion for immersing a body, a hand and a foot of a human body,
A sub-bath part for washing hair and a partition part for partitioning both bath parts are integrally formed of reinforced plastic, and further, in the central upper part of the partition part, a recess for supporting the neck is formed. The bather can take a bath in a comfortable posture lying down, and since the bather is lying down in this way, it was easy for the bathing caregiver to wash the body of the bather.

[0004]

However, although the above-mentioned conventional bathtub can be bathed in a relaxed posture, it still has the following problems to be solved.

The water pressure of hot water at the time of bathing has a great influence on the heart rate of the human body, and in particular, when long-time hot water is taken, it is a burden on the heart when leaving the bath (that is, by releasing the water pressure). Is big. This burden on the heart is an important issue for people with weakened circulatory system, such as the elderly,
Especially in winter, blood vessels may contract or expand in a short time due to temperature changes during bathing (low temperature during undressing, high temperature during bathing). If the burden of water pressure increases, it will have a great impact on the body. Therefore, not only the first conventional technique of bathing in a sitting posture but also the second conventional technique of bathing in a lying posture is affected by the water pressure as described above, if not as much as the first conventional technique.

In both the sitting posture of the first conventional technique and the lying posture of the second conventional technique, the body is soaked that the whole body is soaked in water, which causes buoyancy and makes the body unstable. .

Since both of the conventional techniques have a structure for storing hot water, it is difficult to adjust the hot water temperature of the entire bath to a desired temperature. That is, when adjusting the hot water temperature, the hot water temperature is increased by adding hot water or reheating it, or the hot water temperature is lowered by adding water to bring the hot water temperature to a desired temperature. However, since the amount of hot water in the bathtub is large and the temperature is adjusted by exchanging heat with this large amount of hot water, it takes time to reach the desired temperature, and moreover Therefore, a temperature difference is likely to occur, and it is difficult to set the entire temperature to a desired temperature.

Both of the conventional techniques can take a comfortable bathing posture, but cannot wash the body in this comfortable posture.

After taking a bath, the body is taken out of the bathtub and wiped with a towel or the like to remove water, but in winter or the like, there is a possibility that the water will be cooled.

In the bathtub of the second prior art, when a caregiver performs a washing action, a wiping action of water or the like on a bathing person, these actions cannot be performed in the bathing posture as described above. It is necessary to move the body of the bather, which is extremely labor intensive.

The present invention focuses on the above-mentioned conventional problems,
In addition to reducing the burden on the heart, bathing in a stable posture, accurate and quick temperature control, washing the body in a comfortable posture, and reducing the labor of caregivers, prevent the waste of washing liquid or hot water. The first purpose is to keep hot water clean in order to prevent waste of the cleaning liquid or hot water, and the second purpose is to easily remove water attached to the body without cooling with hot water after bathing. The third purpose is to

[0012]

In view of the above, the present invention uses a bathtub having an inclined structure in which a bather is supported in a lying position, and warm water or washing liquid is made to flow from the shoulder position of the bather toward his feet. , The drainage from the feet is collected and reused to achieve the above-mentioned first object, a filter for removing dirt is provided in the middle of the circulation path to achieve the second object, and the dryer is installed in the bathtub. To achieve the third object.

That is, in the bathtub control device of the present invention, the bath bottom surface can be supported in a posture in which the bather is laid on his back.
Back support that supports the back, waist support that supports the waist,
The leg support part that supports the legs is formed continuously, and the lower part of the leg support part supporting the heel is arranged lower than the upper part of the back support part supporting the shoulder area. A formed bathtub, a supply port arranged near the upper part of the back support portion of the bathtub for flowing out the supply fluid toward the shoulder of the bather, and a hot water supply device for supplying hot water toward the supply port. Also, a cleaning liquid supply device for supplying a cleaning liquid to the supply port, a drain port arranged near the lower portion of the leg support portion of the bathtub, and drainage to this drain port for circulation to the supply port. The circulating device and the control means for controlling the amount and temperature of hot water supplied by the hot water supply device, the operation of the cleaning liquid supply device, and the operation of the circulation device are provided.

The circulating device may be provided with a filter for removing dirt in the circulating waste water. Moreover, you may provide the said bathtub with the dryer which dries a bather.

[0015]

[Function] When taking a bath, the bather lays on his / her back on the bottom of the bath. That is, by placing the back on the back support portion on the bottom of the tank, placing the waist on the waist support portion, and placing the legs on the leg support portions, the feet side is slightly lowered and the person is in the supine state. Then, when the hot water supply device operates based on the control of the control means, the hot water of the optimum temperature flows out from the supply port, toward the lower inclined portion of the tank bottom, that is, toward the drain port at the bottom of the leg support portion. Flowing. Therefore, the warm water flows while soaking the whole body from the shoulder portion of the bather to the heel portion in the state of lying on the bottom of the bath, and the bather can obtain a bathing feeling by the flow of the warm water. Note that the amount of hot water in the bathtub is determined by the relationship between the amount of hot water supplied and the amount of drainage from the drainage port at this time, which also determines the water level in the bathtub. And the bather has a lying position,
Even if the water level is raised, the amount of hot water in the bathtub is small.

As described above, since the bather takes a bath while lying down in the bathtub, the heart portion is not pressed by the water pressure, and even if long bathing is performed, the heart is received when leaving the bathtub. The burden is small and the stability against buoyancy is high.

Next, when the temperature of the hot water supplied by the hot water supply device is changed by the control of the control means, the temperature of the hot water flowing from the shoulder part of the bather to the heel part changes to the newly adjusted temperature, and the bath The temperature of the hot water with which the entire body of the person comes into contact quickly becomes the desired temperature. Moreover, since the amount of hot water in the bathtub is small, the temperature effect by the hot water before the change is small when the temperature is changed, and accurate temperature control can be performed.

Next, when washing the body, if the washing liquid supply device is operated, the washing liquid flows out from the supply port like the hot water. In this case, the warm water and the cleaning liquid may be mixed and supplied. In this way, the bather's body can be washed with the cleaning liquid supplied from the supply port. Therefore, at the time of washing, the bather can wash the body in the bathtub in the same posture as when taking the bath. Therefore, it is easy to take care of a bather without having to move the bather.

After washing the body, hot water is again supplied from the hot water supply device to wash away the washing liquid attached to the body.

As described above, the warm water or the cleaning liquid flowing out from the supply port goes to the lower drain port, but is not drained to the outside from this drain port, but is circulated by the circulation device, and again from the supply port. Can be drained to the bathtub.
As a result, it is possible to prevent wasteful use of hot water or cleaning liquid. Further, in the apparatus according to the second aspect, dirt in the warm water or the cleaning liquid can be removed by the filter during this circulation.

Next, when the bathing is finished, in the apparatus according to the third aspect, the hot water in the bathtub is drained, and then the dryer is operated to remove the water adhering to the body of the bather. Therefore, it is possible to dry the body without leaving the bathtub, and it is easy, and quick drying is performed, and it is difficult to cool the hot water.

Step 115 is a step of stopping the operation of the dryer 13 and driving the cover opening / closing actuator 14b to open the cover 14. This completes one flow.

(Operation of Embodiment) The bathing procedure will be described. The bather M lays on his / her back on the bottom surface 11 of the bathtub 1 as shown in FIG. When the head of the bather M is placed on the head support portion 11a in this way, the human detection sensor 6
Detects a person. Then, the bather himself or a caregiver selects a desired hot water amount and hot water temperature with the hand switch 7.

In response to this operation, the switching valve 15 is switched to the position for supplying hot water, the hot water supply device 8 is operated, and further the slit opening / closing actuator 3a.
Operates (steps 101 → 102 of the flowchart)
→ 103 → 104 flow). As a result, hot water having a desired amount of hot water and hot water flows out of the hot water supply device 8 through the switching valve 15, the hot water flow path 1b, and the supply port 3.

The hot water flowing out from the supply port 3 is
Heading to the lower part along the bottom 11 of the tank, that is, the neck rest 1
It passes through the back support portion 11c from the vicinity of 1b, further flows down from the waist support portion 11d to the leg support portion 11e, and then flows into the vertical groove 1a. Therefore, the hot water will flow while bathing the whole body from the shoulder part of the bather M who is lying on the bottom surface 11 of the bath to the heel part.
The bather M can get a feeling of bathing. At this time,
Although the first drain cock 5 of the drainage port 4 is opened, by squeezing the first drain cock 5 to some extent, it is possible to raise the water level and enhance the feeling of bathing. Therefore, the amount of hot water in the bathtub 1 is small even if the water level is raised.

As described above, since the bather M takes a bath by immersing his body in the warm water flowing while lying down in the bathtub, even if he takes a long bath, the heart is not pressed by the water pressure. The burden on the heart when leaving the bathtub 1 is small, and the stability against buoyancy is high.

Next, when changing the hot water temperature, the hand switch 7 is operated again to change the setting of the hot water temperature supplied by the hot water supply device 8. As a result, the temperature of the hot water flowing from the shoulder portion of the bather M to the heel portion is changed to the newly set temperature, and the temperature of the hot water with which the whole body of the bather M is in contact quickly becomes a desired temperature.

In changing the temperature in this way, a warm water flow is made to flow while bathing the whole body from the shoulder part of the bather M toward the heel part, and the temperature of this flow is changed. The hot water temperature can be controlled. Moreover, at this temperature, the hot water of the temperature before the change in the bathtub 1 is shallow in the bathtub 1 and basically forms a flow of hot water so that a large amount of hot water cannot be stored.
Since the amount of hot water is small, the temperature effect of the hot water before the change is small, which also enables accurate temperature control.

Furthermore, when an operation for adding a chemical such as a bathing agent into warm water is performed by the hand switch 7 at the time of bathing as described above, the switching valve 15 is switched to the position for supplying the chemical and the chemical addition device 12g is operated. Then, the chemical liquid is added to the warm water supplied from the supply port 3 as described above (step 105 → 106 flow).

Next, when washing the body of the bather M,
The hand switch 7 is operated to operate the cleaning liquid supply device 12h, and at the same time, the switching valve 15 is switched to the cleaning liquid addition position (step 107 → 108). Thereby, the warm water to which the cleaning liquid is added is supplied to wash the body. Thus, when washing the body, the bather M does not need to change the posture of the body at the time of bathing, and in particular, when a person with a physical disability takes a bath, the caregiver uses the caregiver M to wash the body. There is no need to move the caregiver, and the caregiver's labor can be greatly reduced.

At the time of cleaning, the cleaning liquid is circulated.
That is, the first and second drain cocks 5 and 12f are closed, and the warm water containing the cleaning liquid that has flowed down into the vertical groove 1a is sucked by the circulation pump 12b, is filtered by the filter 12c on the way, and is recovered after the dirt is removed. It is stored in the container 12d, is again supplied from the collector 12d through the switching valve 15 to the supply port 3, and is repeatedly circulated (step 10).
8). Therefore, waste of the cleaning liquid can be suppressed, and even if the cleaning liquid is circulated in this way, the dirt is not circulated by removing the dirt with the filter 12c.

After the washing of the body is completed as described above, the hot water is again supplied by the hand switch 7 to wash the washing liquid attached to the body (step 109 →
110 → 102). In this case, the first and second drain cocks 5 and 12f are opened, and the hot water or bath agent and the cleaning liquid in the bath 1 and the collector 12d are drained.

Next, when the bath is finished, if the switch 7 is operated, the operation of the hot water supply device 8 or the chemical liquid addition device 12g and the cleaning liquid supply device 12h or the circulation device 12 is stopped, and The second drain cocks 5, 12f are opened (step 109 → 1)
11). As a result, all of the hot water, the bath agent, and the cleaning liquid in the bath 1 and the collector 12d are drained.

Further, at this time, when the hand switch 7 is operated to perform drying, the cover opening / closing actuator 14b is driven to reach a position where the cover 14 covers the bather M as shown in FIG. It slides, and the dryer 13 is activated to blow hot air into the bath 1 (steps 112 → 113). Thereby, the water adhering to the body of the bather M is removed.

As described above, after the bath is finished, the body of the bather M is immediately dried in the bathtub 1 without going out of the bathtub 1. Therefore, there is no need to wipe the body by himself, and in particular, there is an obstacle. It is extremely convenient for people with disabilities, such as the elderly and the elderly, and it is difficult to cool the body without cooling the body. In addition, the caregiver does not need to wipe the body of the bather M, which also can significantly reduce the labor of the caregiver.

After that, when the operation for ending the drying is performed by the hand switch 7, the operation of the dryer 13 is stopped, and the cover opening / closing actuator 14b is driven to open the cover 14 (steps 114 and 115), and the bath is taken. Person M exits bathtub 1.

As described above, in this embodiment, the effects listed below can be obtained.

Since the bather M takes a bath in a state of lying down in the flow of warm water, it is possible to reduce the burden on the heart without the heart portion being pressed by water pressure.
Stable bathing is possible without being much affected by buoyancy.

When changing the temperature of the hot water, the temperature of the hot water flowing out from the supply port 3 is changed to immediately change the temperature of the hot water with which the whole body of the bather M is in contact with the desired temperature, so that the temperature can be adjusted accurately and quickly. Can be achieved.

At the time of washing the body, the bather M can wash in the bathtub 1 in the same posture as when bathing,
It is easy to wash, and especially when the caregiver cleans a physically handicapped person, the caregiver does not need to move the bather, and the labor of the caregiver can be greatly reduced.

Since the dryer 13 and the cover 14 are provided so that the body can be dried while being in the bathtub 1, it is not necessary to wipe the body with a towel or the like, and the body does not get cold, so there is no worry of cooling with hot water. And
In this way, it is not necessary to wipe the body, so in particular,
It is convenient for the physically handicapped person, and the labor of the caregiver can be greatly reduced.

As described above, the controller 9 carries out overall control relating to bathing, such as control of the amount and temperature of hot water during bathing, addition of chemicals such as bathing agents, control of addition of cleaning liquid, and circulation control of cleaning liquid. It is possible to provide a new device with excellent usability. Further, in performing the control by the controller 9 in this way, the human detection sensor 6 is provided, and the bather 1 is automatically detected after the bather M is detected.
It is easy to use because hot water is supplied inside.
In addition, since the hand switch 7 as a means for operating the amount of hot water and the hot water temperature is arranged at the portion where the hand of the bather M is placed, the bather M can operate without going out of the bathtub 1 and is convenient to use.

The neck supporting portion 11b and the head supporting portion 11a are continuously formed on the upper side of the back supporting portion 11c to support the head of the bather M, and the waist supporting portion 11d is slightly upward. Since the load of the upper half of the body is supported at this part and the total load is not required to be supported by the foot, bathing is very easy.

Since the tank bottom surface 11 is formed on the upper surface of the mat 2 made of foam made of sponge-like resin,
It has a soft texture and is comfortable to sleep, and it is also non-slip and can hold a stable body.

Although the embodiment has been described above, the specific structure is not limited to this embodiment, and the present invention includes a design change and the like within a range not departing from the gist of the invention. For example, in the embodiment, the dryer 13 and the cover 14 are provided to give the bathtub 1 a drying function.
This function is not absolutely necessary.

Further, in the embodiment, the slit member 3b is provided and the amount of hot water is controlled by this member 3b and the hot water supply device 8, but the amount of hot water may be controlled by only one of them. Further, the head support portion 11a and the neck rest portion 11b are not essential, and both are not included in the bathtub 1
It may be formed on the side wall portion of the.

In the embodiment, the circulation device 12 circulates only when the cleaning liquid is used, but it may be circulated when only hot water is supplied. In this case, the amount of hot water used is reduced, which is economically superior. Also during this circulation, the hot water is filtered by the filter 12c so that the hot water is not contaminated.

In the embodiment, the switching valve 15 is used to mix the cleaning liquid or the chemical liquid with the hot water, but the switching valve 1
The cleaning liquid or the chemical liquid may be caused to flow in the middle of the flow path of the hot water without going through 5, or the cleaning liquid may be supplied into the bathtub through a flow path completely different from the hot water.

[0073]

As described above, the present invention claims 1.
In the bathtub control device described, the bath bottom is formed so as to be able to support the bather in a lying position, and a bathtub having a structure in which hot water is drained by flowing hot water from the position of the bather's shoulder toward the feet, Since a hot water supply device that supplies hot water, a cleaning liquid supply device that supplies a cleaning liquid, and a circulation device that circulates the drainage to the drain port are provided, when bathing, the bather bathes while lying down in the flow of hot water. As a result, it is possible to reduce the burden on the heart because the heart is not compressed by water pressure, and it is possible to obtain a stable bath without being affected by buoyancy. When changing the hot water temperature, by changing the temperature of the hot water flowing out of the supply port, the temperature of the hot water contacting the entire body can be immediately changed to the desired temperature. The effect is that adjustment can be achieved, and in addition, the body can be washed without going out of the bath while lying down while bathing. When a caregiver washes a person who does not need to be moved, the caregiver does not need to move the bather, and the labor of the caregiver can be significantly reduced. In addition, warm water or cleaning solution can be circulated. Although it is a bath having a structure in which hot water or a cleaning liquid is bathed while flowing, the effect that the amount of the hot water or the cleaning liquid used is small and it is economically excellent.

Further, in the bathtub control device according to the second aspect,
Since a filter was installed in the middle of the circulation device and used hot water or cleaning liquid was once filtered and sent to the hot water supply device, there is an effect that it is possible to always supply clean hot water or cleaning liquid even when circulating hot water or cleaning liquid. can get.

Further, in the bathtub control apparatus according to the third aspect,
Since the dryer is installed in the bathtub, the bather can dry his body without getting out of the bathtub, which saves the time and effort of wiping the body and is convenient, as well as avoids the need to quickly dry the body and cool it with hot water. In particular, when the caregiver takes care of bathing a physically handicapped person, there is no need to lift the bather or move it out of the bathtub when wiping the body. The labor of the caregiver can be greatly reduced.
