CIRCULATORY FILTRATION STERILIZATION FOR BATHING DEVICE AND CIRCULATORY FILTRATION STERILIZATION DEVICE

Japanese Patent JP3829267

B2

PROBLEM TO BE SOLVED: To provide a sterilization method for preventing bacterial proliferation from occurring in a circulatory filtration sterilization device using a residual hot water after bathing and a sterilization device using the sterilization method.
SOLUTION: In the circulatory filtration sterlization method using a bathing device 100 equipped with a circulatory filtration sterilization unit 60 which performs filtration and sterilization by draining hot water W from a bath tub body 30 to the outside of the bath tub and again returns the hot water W to the interior of the bath tub body 30, when the residual W1 of the hot water W is at a low level L during draining the hot water W from the bath tub body 30, a chlorine solution is injected into the circulatory filtration sterilization unit 60 and circulatory ductworks 53, 55. Thus, it is possible to increase the concentration E1 at a routine level of chlorine E to a higher concentration level E2 as a circulatory filtration sterilization method. The proliferation of bacteria in the circulatory filtration sterilization device or the like is prevented from occurring.
