Within 1. Here, when electricity is supplied to the anode 57 and the cathode 58, water is electrolyzed, and acidic water is generated on the anode 57 side and alkaline water is generated on the cathode 58 side. That is, the hydroxide ion OH contained in the water in the anode 57 by electrolysis ^- is consumed becomes acidic by hydrogen ions H ⁺ concentration increases, the reverse is consumed hydrogen ions H ⁺ in the cathode 58 side Hydrogen gas is generated, and the concentration of hydrogen ions is reduced to make it alkaline. Note that the diaphragm 59 has an ion exchange action,
Acidity and alkalinity can be efficiently increased in proportion to the electrolysis time. Here, acidic water having a predetermined value or more has a bactericidal action, and alkaline water has an action of decomposing a dirt component such as protein on the bathtub wall.

洗浄され、洗浄度が向上する。The three-way valves 62 and 63 are controlled so that the strong alkaline water on the side of the cathode 58 is first supplied to the supply unit 48 among the generated electrolytic water. Since acidic water and alkaline water are generated at the same time by the electrolysis, the acidic water is discarded from the waste passage 64. Then, strong alkaline water is sprayed from the injection nozzle 29 of the cleaning adapter 20, and the bathtub 18 and the bathtub lid 28 are cleaned. This cleans the stains on the bathtub 18 and the bathtub lid 28 that have not been completely decomposed by the cleaning agent, and improves the degree of cleaning.

的な洗浄性能が得られる。As described above, by spraying the alkaline water after the preliminary cleaning, the action of decomposing and cleaning the alkaline water can be more effectively exerted. That is, when the alkaline water is sprayed in a state where the chemical cleaning agent remains, the chemical cleaning agent and the alkaline water chemically react on the surface to be cleaned, for example, the alkalinity is reduced, and a sufficient cleaning effect cannot be obtained. Preliminary cleaning removes the chemical cleaning agent in advance, thereby preventing a chemical reaction and obtaining effective cleaning performance.

る。Next, fresh water is again sprayed into the bath tub to wash out the alkaline water, and the sterilization step, which is the final step, is started. That is, the cleaning agent generating means 53 operates again to perform electrolysis, and the strongly acidic water is sprayed into the bathtub through the supply unit 48. Since the acidic water has a bactericidal action as described above, the bathtub 18 and the bathtub lid 28 are finally sterilized, thereby preventing the growth of bacteria and fungi. This is particularly effective for maintaining the cleanliness of the bath lid 28 in which bacteria and fungi are likely to propagate.
