BATHTUB CLEANING SYSTEM

PROBLEM TO BE SOLVED: To provide a bathtub cleaning system stably satisfying the cleaning property and the rinsing property of the bathtub by uniforming the detergent concentration of the mixed liquid of warm water and a detergent for spraying into the bathtub regardless of the quantity of the detergent stored in a detergent tank. SOLUTION: A mixing portion 13 and a spraying portion 16 arranged in the bathtub 11 are connected by a warm water supplying conduit 20, and the mixing portion 13 and the detergent tank 12 are connected by a detergent supplying conduit 21. An electric three-way valve 14 is arranged in the detergent supplying conduit 21, and a vent pipe 24 opened to the atmosphere is connected to the electric three-way valve. Further, a detergent storing portion 23 installed in a substantially horizontal direction is formed in a mixing portion 13 side of the electric three-way valve 13 of the detergent supplying conduit 21. The inside of the bathtub 11 is cleaned by using only the detergent in the detergent storing portion 23 separating the detergent tank 12 and the detergent storing portion 23 by the electric three-way valve 14 after the inside of the detergent storing portion 23 is filled with the detergent when spraying the detergent into the bathtub 11.
