[0011]

The effects of the present invention are as follows.

A. Since the detergent is sprayed over the entire area of the bathtub and the chemical power is used to decompose and remove the dirt, the operating cost is lower than that of the system in which the washing water is circulated.

B. Use of water or hot water is minimal, which is effective in saving water.

C. The device can be set by simply connecting the connected body to the drain valve in the bathtub in combination with the bath water heater with automatic hot water reheating function, minimizing equipment work, especially easy installation on the existing bathtub Can be used.

D. Since all functions are incorporated in the casing that can be taken in and out of the bathtub, it is convenient to install it in the bathtub only at the time of washing and pull it up so that it does not interfere with bathing .

E. You can enjoy bubble blow.
