<< Operation >> Since the opening of the recess of the housing is closed in a liquid-tight state by the cover plate, a sufficient amount of hot and cold water necessary for bathing is stored in the bathtub.

Draining of hot and cold water in the bathtub and cleaning of the bathtub are performed as follows.

In claim (1), by opening a drain port provided separately on the bottom wall of the bathtub, the hot and cold water in the bathtub is drained,
When the water level is drained from the drainage system and the water level drops to the position of the water level sensor arranged in the bathtub, the water level sensor detects the water level, and the water supply system operates according to the water level detection signal. Cleaning water consisting of a cleaning liquid system connected to the housing is supplied to the water supply and sliding hole of the housing.

When the cleaning water is supplied to the water supply / sliding hole, the cleaning water is sprayed from each nozzle passing through the water supply cylinder. Therefore, since the amount of water supplied from the water supply system to the water supply / sliding hole is considerably large,
The wash water injection mechanism receives the water pressure of the wash water and is pushed up.

As a result, the lid plate is pushed up, the opening of the recess is opened, and the wash water injection mechanism is pushed up to a position where each nozzle projects from the recess into the bath by a required dimension.
Held in that position.

Therefore, the cleaning water is sprayed from the nozzles onto the inner wall surface of the bath, so that the deposits on the inner wall surface are washed away by the cleaning water and its water pressure.

The deposits and washing water flowing down to the lower part of the bathtub flow into the recess of the housing, and are discharged to the outside through the drainage system from the drainage hole opening at the bottom.

Further, since the injection direction of the nozzle is variable, the nozzle can be adjusted according to the size and shape of the bathtub.

Furthermore, in claim (2), the water pressure of the hot water stored in the bathtub acts on the upper surface of the lid plate,
The lid plate bends downward, whereby the air in the air chamber is compressed and passes through the introduction pipe to turn on the diaphragm switch, etc.
The water supply system is kept in the OFF state.

Therefore, the hot and cold water in the bathtub is drained from a separately provided outlet, the hot and cold water reduces to a preset amount of water, and when the water pressure decreases, the lid plate elastically returns upward and compressed air is introduced. Since it is not supplied to the diaphragm switch through the pipe, the diaphragm switch will be turned off, and the water supply system will be turned on in conjunction with this, so that cleaning water is supplied to the water supply / sliding hole. In addition, the cleaning water spraying mechanism is pushed up to open the cover, and the cleaning water is sprayed from the nozzles protruding into the bathtub onto the inner wall surface of the bathtub for cleaning.

Further, the deposits and the cleaning drainage flowing down to the bottom of the bathtub are discharged to the outside from the recess through the drainage system.

<Effect of the Invention> Since the present invention is configured as described above, in claims (1) and (2), since the opening of the recess of the housing is usually covered with the lid plate, it is possible to take a bath. During cleaning, the lid plate is automatically opened by the water supply pressure during cleaning, so it is not necessary for a person to bend over to remove the lid plate, and the flush water injection mechanism is used. Since the washing water is pushed up and is ejected from the plurality of nozzles protruding into the bathtub to the inner wall surface of the bathtub, the bathtub can be washed and the directionality of the nozzle itself can be changed. Not only can it respond to the shape and size of the bathtub, but also because it is linked with the water level sensor, it is possible to automate the drainage and cleaning, which is the most time-consuming preparation for bath preparation.

Further, in claim (2), since the pressure introduction pipe for the water level sensor is arranged at the center of the device, it is possible to automate the drainage and cleaning in conjunction with the water supply system without separately providing the water level sensor in the bathtub. Can be achieved.
