Abstract

PURPOSE: To intend to purify warm water in the bathtub and to protect the dirts from sticking to it due to positioning a waterline inside the bathtub by making the warm water overflow from a periphery part to circulate it. CONSTITUTION: Before bathing, warm water is stored in a bathtub 1 in a state overflowing from its opening 11, electricity is turned off with an operation switch. When going out from the bathtub 1 after sinking a human body, water level falls down. This is detected by a water level switch S to drive a pump P, and washed water stored in an overflow room 10 is supplied into the bathtub 1. When reaching an overflowing water level from the opening 11, the water level switch S is changed its constant point, but the pump P continues its operation for a setting time of a timer. In a connected tube 12 a filter F is mounted to purify the circulated warm water.
