摘要： PROBLEM TO BE SOLVED: To prevent attachment of both water sludge to devices for bath water such as pipings and a heat exchanger without using a high-level disinfectant. SOLUTION: This system comprises a bathtub 1, and a device for bathwater (water boiler 30) having a circulating means 3 and connected to the bathtub 1 by an outgo pipe 20 and a return pipe 21. In this case, in the outgo pipe 20, a silver ion supply device 6 to supply silver ions is provided. The silver ions generated by the silver ion supply device 6 are thus sent to flow the inside of the device for bathwater (water boiler 30) keeping a high concentration close to a generated condition. Effective microorganism disinfecting effect is thus generated, and propagation of microorganisms in the device for bathwater (water boiler 30) can be prevented, thereby generation of bath water sludge ca be prevented for a long period without using high-concentration disinfectant.

摘要： PROBLEM TO BE SOLVED: To improve detergency and sterilizing power by providing the device with an electrolytic water forming means for forming electrolytic water from fed water. SOLUTION: When the portable washing device 10 is put into the state of gripping a tank 18 in such a manner that a nozzle 24 faces downward and a water inlet port 12 faces upward, the city water admitted from the water inlet port 12 is introduced into an electrolytic cell 14 and acidic water is formed in the anode chamber of the electrolytic cell 14 and alkaline water in the cathode chamber by an electrolysis reaction. Each formed water is stored in an acidic water chamber 18a and an alkaline water chamber 18b at the rear stage, respectively. When a user thereafter pushes a discharge button 22 after selecting the desired kind of the water, i.e., either the alkaline water or the acidic water with an alkaline water-acidic water switching button 20, the water of the kind selected by the user is ejected from a discharge port 24a via the nozzle 24 from the acidic water chamber 18a or the alkaline water chamber 18b.

摘要： PROBLEM TO BE SOLVED: To provide a tap water treatment apparatus of which the life of cation exchange resin cartridge having high ion exchange efficiency is prolonged and provide a treatment method by the apparatus. SOLUTION: A cation exchange resin cartridge 2 filled with a cation exchange resin 10 is so formed as to have a curved and projected upper center part and a structure in which tap water to be introduced into the inside of the cartridge enters through the peripheral part of the lower part of the cartridge and flows out of the lower center part. Consequently, the cation exchange resin 10 packed in the inside of the cartridge 2 and tap water are surely brought into contact with each other and ion exchange is efficiently carried out and the life of the cartridge is practically prolonged. Moreover, the same effect can be obtained by arranging a spiral guide member in the inside of the cartridge 2 or making the particle size of the cation exchange resin near the outlet larger than near the inlet by forming the outlet into a taper shape with a cross- section surface area smaller than that of the inlet, instead of the above- mentioned structure.
