Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to
The present invention relates to a bathtub device that can easily wash the body of a bather.

[0002]

2. Description of the Related Art In medical facilities and the like, patients such as physically handicapped sick people and elderly people may be bathed.

The bathing equipment used in such a case is not different from the one installed in a general household, and therefore,
The patient takes a bath in the bathtub with the help of a caregiver or the like, and the caregiver needs to wash the body of the bather carefully with a sponge or towel.

[0004]

However, according to the prior art, there is a problem that the caregiver has to wash the whole body of the bather in the bathtub, which requires excessive labor. Further, since the bather's body is washed in the bathtub, there is a problem that the hot water is easily soiled and a lot of waiting time is required to replace the hot water.

Therefore, in view of the problems of the prior art, an object of the present invention is to arrange a nozzle in a bath with a filtration tank so as to automatically wash the body of a bather in the bath to assist the caregiver. It is an object of the present invention to provide a bathtub device that can reduce the labor of the bathtub, keep the hot water in the bathtub clean, and significantly reduce the frequency of hot water replacement.

[0006]

The structure of the present invention for achieving the above object includes a bathtub, a filtration tank for circulating and purifying hot water in the bathtub, and a nozzle arranged along the side surface of the bathtub. The gist of the nozzle is to eject hot water into the bathtub to form a jet jet.

The bathtub can be provided with a backrest in which a bubble generator can be arranged at the bottom.

Further, the bathtub can be provided with an active bath which can mix air into the hot water from the filtration bath and activate the hot water in the bathtub.

[0009]

According to the structure of the present invention, the filtration tank circulates and purifies the hot water in the bath, while the nozzles arranged along the side surface of the bath eject the hot water into the bath to form a jet jet. Since the bath is formed, the bather in the bathtub can wash the body automatically by the jet jet without the need for the helper's hand, and the work of the helper can be greatly reduced.
In addition, it is preferable that a large number of nozzles are arranged in at least three directions of the bath so that a jet jet is formed in the entire bath.

When the bubble generator is installed at the bottom of the bathtub, the bubble generator generates countless bubbles in the bathtub, and the bubbles burst to generate ultrasonic waves.
The cleaning effect of the bather can be further improved.

If the bathtub is provided with a backrest, the bather can lean on the backrest and maintain a natural posture without difficulty.

When air is mixed in the hot water from the filtration tank,
Air bubbles are generated in the bathtub, and the same effect as that of the bubble generator can be obtained.

When the bath is equipped with an active tank, the active tank suppresses the decay of the hot water due to anaerobic bacteria, and, for example, silicic acid, alumina, iron, calcium, sodium, potassium, magnesium, molybdenum, cobalt, germanium, etc. It is possible to elute the minerals mentioned above and harden the hot water in the bath to further improve the bathing effect. However, it is assumed that the active tank is filled with an active material such as ore serving as a mineral source, and the hot water from the filtration tank is returned to the bath through the active tank.

The rear portion of 5b is bent obliquely upward. Therefore, the sheet material 45a has an inclined surface at the rear portion and a long flat surface at the front portion, following the shape of the frame material 45b.

The operation of the bathtub device is as follows.

When the water faucet 17 is opened and the water heater 18 is operated, the hot water HW can be stored in the bathtub 10. This is because the water heater 18 can heat the water from the water source S to an appropriate temperature. When the hot water HW is sufficiently stored in the bathtub 10, the valves V1 and V2 are opened and the pump P1 is operated. Then, the pump P1 sucks the hot water HW in the bathtub 10 through the suction port 15, and the filtration tank 21 and the active tank 22.
After filling the inside, it can be returned into the bathtub 10 through the jet port 16. At this time, the ejection port 16 can mix an appropriate amount of air into the hot water HW through the air pipe 24 by adjusting the adjusting body 16c to discharge bubbles into the bathtub 10.

The pump P1 is the hot water HW in the bathtub 10.
By circulating the water in the filter tank 21 and the active tank 22, the hot water HW is continuously purified through the filter tank 21, and
The hot water HW can be appropriately hardened and activated through the activation tank 22. This is because the filter tank 21 filters the hot water HW with the filter 21c, and the active tank 22 elutes the mineral components from the active material 22c into the hot water HW. In addition,
The heater 23 in the active bath 22 keeps the hot water HW in the bath 10 warm by controlling energization via a temperature controller (not shown). In addition, the pump P1 is driven by variable speed driving, for example, via an inverter drive motor, so that the hot water H
The circulation amount of W can be arbitrarily adjusted and set.

The lift 40 mounts a bather on a bed 45, moves it on the bathtub 10 and fixes it, and lifts and lowers the frame 43.
The bather can be bathed by lowering and lowering the bed 45 into the bathtub 10 (two-dot chain line in FIG. 7). At this time, the valves V3, V3, V4, V4
Open and open the pumps P2 and P2.
the hot water HW in the bathtub 10 through the nozzles 31,
It can be ejected from 31 ... Nozzle 31, 31
... can form a jet jet in the whole bathtub 10 and can automatically wash the body of the bather on the bed 45 in the bathtub 10. Furthermore, at this time, the air compressor C
When a large amount of bubbles are generated from the bubble generator 32, the bubbles are ruptured on the surface of the body of the bather and ultrasonic waves are generated, so that the bathing person's cleaning effect can be improved.

When the body of the bather on the bed 45 is thoroughly washed, the bed 45 of the lift 40 is raised and fixed,
The lift 40 may be moved from the bathtub 10 to lower the bed 45 to lower the bather.

Since the filter 21c of the filtration tank 21 becomes dirty and the purification ability of the hot water HW deteriorates with time, the purification ability is restored by appropriately cleaning or replacing it. Further, the active material 22c of the active tank 22 can also be periodically removed from the active tank 22, washed and dried to restore the active capacity.

In the above description, the pumps P2, P2,
Air compressor C, via a suitable timer switch,
You may make it operate automatically according to the bathing time of the bather. Further, the lift 40 need not be used at all for a bather who can bathe by himself.

The bathtub 10 can be configured to be movable by using an appropriate caster in place of the mounts 11, 11. The filter tank 21, the active tank 22, the pumps P1, P2, P2, and the air compressor C at this time are housed in a box attached to the bathtub 10,
It is preferable to be movable together with 0. Further, the water faucet 17 may be replaced with a water faucet with a shower.

As described above, according to the present invention, the nozzle is formed by providing the bathtub, the filtration tank for purifying the hot water in the bathtub, and the nozzle for forming the jet jet in the bathtub. Since the jet jet can effectively clean the body of the bather in the bathtub, the labor of the caregiver can be greatly reduced, and the filtration tank can keep the hot water in the bathtub clean. The excellent effect is that the frequency of hot water exchange in the bathtub can be significantly reduced.
