[0002]

2. Description of the Related Art An ordinary bath tub has a box shape with an open top, and a bather must straddle the side wall to enter the bath tub. Therefore, the following bathing apparatus combining a wheelchair and a door opening / closing bathtub has been developed so that people with physical disabilities can easily take a bath.

[0003] That is, a bather is placed on a wheelchair, and is run on a slope arranged so as to be connected to an opening of a door closable tub with a side door opened, and the wheelchair on which the bather is placed is opened and closed. It is located at a predetermined position inside the bathtub. Thereafter, the bath is a bathing device that closes the door, closes the opening of the door opening / closing bathtub body in a watertight state, and fills the inside of the bathtub body with hot water to bring a bather on a wheelchair into a bathing position in a sitting position. .

By the way, the above-mentioned conventional bathing device has the following problems. A wheelchair with a bather is run on a slope that is arranged so as to connect to the opening of the openable door tub, and the casters of the wheelchair are made to enter the bathtub.
There is a risk that dirt on the floor of the corridor and bathroom may be brought into the bathtub through the caster, and there is a problem in terms of sanitation. It is necessary to push the wheelchair with the bather on it while climbing the slope that connects to the door-opening bathtub, and the casters at the bottom of the wheelchair can change direction and the casters themselves are often wet. Therefore, it is difficult to move the wheelchair straight, and the assistance work is very troublesome. With the slope set at the proper position, the slope and the lower part of the door interfere with each other, so that the bathtub door cannot be opened and closed.Each time the bathtub door is opened and closed, the tip of the slope is lowered, There is a problem that the slope has to be separated from the bathtub, and the work is troublesome.

As a bathing device for coping with such problems, the present inventors transport a bather placed on a wheelchair together with the wheelchair, and a predetermined position inside a door opening / closing bathtub having a sealing mechanism at the bottom. When the door is closed, at the same time when the door is closed, the seal mechanism at the bottom is operated to seal the upper and lower parts of the wheelchair liquid-tight, and the hot water is filled inside the door openable bathtub which is the upper side of this seal. , Developed a bathing device for putting the bather in a bathing state.

[0006]

However, it has been found that even in this type of bathing apparatus, there still remain the following problems to be improved. That is, when hot water exists inside the bathtub and a caregiver or a bather accidentally opens the door of the bathtub body, the hot water inside is discharged into one machine, and the hot water is wasted. Another problem is that hot water overflows into the bathroom, causing trouble to other bathers.

The present invention has been made in view of the above circumstances, and in the state where hot water is present inside the bathtub, even if a caregiver or the like accidentally turns on the switch for opening the door, the bathtub body for opening and closing the door is opened. It is an object of the present invention to provide a bathing device that does not open the door of the bath.

[0008]

In order to achieve the above object, in the invention according to claim 1, a bather placed on a wheelchair is transferred together with the wheelchair, and a door opening / closing bathtub with a side door opened. A bathing device for placing the bather in a bathing state by filling the inside of the door opening / closing bathtub with hot water after the door is closed at a predetermined position inside the door opening / closing bathtub A lock mechanism that keeps the door closed is provided between the main body and the body, and a sensor that detects whether hot water is present inside the main body of the openable / closed bathtub is used to close the door. It is characterized in that a control device is provided for releasing the lock mechanism only when the sensor detects that there is no hot water in the door opening / closing bathtub body when locked in the state.

According to a second aspect of the present invention, the lock mechanism includes two locks provided at a predetermined distance above and below the door, a link mechanism connecting the two locks, and the link. And a drive cylinder for operating the mechanism.

[0010]

In the bathing apparatus of the present invention, the door is closed with the wheelchair inside, and the closed state of the door is maintained by the lock mechanism. Then, in this state, hot water is filled in the door opening / closing bath. When the hot water is filled, the sensor detects that fact. As described above, while the sensor detects that hot water is present in the bathtub, the lock mechanism continuously locks the door in the closed state via the control device. Therefore, even if a caregiver or a bather accidentally turns on the switch that opens the door, the door will not open as long as there is hot water in the bathtub, and There is no risk of spillage.
