BATH WATER CIRCULATION PURIFYING DEVICE

PROBLEM TO BE SOLVED: To prevent dirt of the tank wall of a bath tank by providing a second discharge pipe branched from a first discharge pipe and effecting a flow of discharge water along a tub wall from the whole periphery of the upper part of a bath tub. SOLUTION: After bath water 3 pumped up through a water suction pipe 5 by operating a circulation pump 4 is heated by a heat source 8, water is purified in a purifying unit 9 through a circulation channel 7. Further, after bath water 3 is sterilized by a sterilization lamp 13, the bath water is returned to the bath tub 2 through a valve 11 and a first discharge pipe 6. A part of a purified bath water 3 is caused to flow in a second discharge pipe 25 and discharged in an atomized state through the pores of the second discharge pipe 25 along the tub wall from the whole periphery of the upper part of the bath tub 2. This constitution brings the tub wall into a wet state and prevents adhesion of dirt to the tub wall to which dirt is heretofore easily adhered.
