HOT-WATER SUPPLYING BATHTUB WITH WATER PURIFYING FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a hot-water supplying bathtub provided with a water purifying function, in which the water level is able to be surely detected even when the seal of a motor-driven three-way valve (water discharge valve) is damaged. SOLUTION: When a circulating pump 16 and a hot-water-supply/heating means 22 are stopped, or when the water level of a bathtub 17 is detected in this bathtub, a linkage between the lower side of a filter 20 and the feeding side of the bathtub adapter 19 a linkage between a bypass circuit 27 and the feeding side of the bathtub adapter 19 and a linkage between the suction side of a circulating pump 16 and the suction side of the bathtub adapter 19 are cut off, respectively and then any change water level in the bathtub is suppressed to prevent a water leakage or to surely detect the water level.
