DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, 1 is a bathtub, 2 is a drain port, and 3 is a drain valve. Reference numeral 4 denotes a main unit, which is installed outside the bathroom, and has a detergent tank 5 , a spray pump 6 for spraying detergent , a control valve 16, and a controller 1 inside.
9 are incorporated.

[0015] 7 and the bathroom unit attached to the wall of the upper edge of the bathtub 1, drain valve switch 8 and drain valve switch 8 in this bath unit 7 to open and close the drain valve 3, a detergent
An inlet 10 is incorporated, and the detergent injected from the detergent inlet 10 is supplied to the detergent tank 5 via a detergent tube 11.
Supplied within. 9 connects the drain valve switch 8 and the drain valve 2
Bathroom unit 7 toward the coupling body 12 is in the bathtub 1 are in
The spray nozzle 13 is attached to the spray pump 6
Is a detergent supply pipe connecting the discharge side of the nozzle and the spray nozzle 12.

Reference numeral 14 denotes a rinsing nozzle attached to the bathroom unit 7 toward the inside of the bathtub 1, and reference numeral 15 denotes a control valve 16 .
The water supply / hot water supply pipe is connected to the rinsing nozzle 14 and the other end is connected to an automatic bath water heater 17. 18
Is a reheating circuit that connects the automatic bath water heater 17 and the inside of the bathtub 1 . Reference numeral 20 denotes a remote controller which controls the controller 19 in a bathroom.
Can be controlled.

The controller 19 performs the following control. a. When the cleaning mode switch of the remote control 20 is turned on, the drain valve switch 8 is driven to open the drain valve 3 to drain the remaining hot water in the bathtub 1 .

B. Next, the water supply control valve 16 is opened to supply water.
Water or hot water supplied to the rinse nozzle 14 from the hot water supply pipe 15,
This is sprayed onto the entire area of the bathtub 1 to wash out large dusts in the bathtub 1 and to wet the inside of the bathtub 1.

C. Next, the drain valve 2 is closed and the spray pump 6

[0022]

The effects of the present invention are as follows.

A. The operating cost is low because the detergent is sprayed over the entire area of the bath tub and the chemical power is used to decompose and remove dirt.

B. Since water or hot water is used only for pre-washing and washing away the detergent, it is effective in saving water.

C. The device can be used with any type of bath water heater.

D. Since the device only needs to connect the opening / closing body to the drain valve in the bathtub and attach the spray nozzle and the rinse nozzle to the bathtub using a suction cup, etc., the installation work for installation is minimal, especially the existing bathtub. It can be easily attached to

E. Since the bathroom unit is divided into a main unit and a bathroom unit, the size of the bathroom unit entering the bathroom can be reduced as much as possible, so that it does not hinder the bathing.
