ウム等の薬剤を用いて配管の洗浄を行う必要があった。However, if the bathtub and the water heater are used for many years, dirt adheres to the bathwater circulation channel at the time of reheating. This is the so-called "Yudoro", which in addition to dirt components such as dirt attached to pipes and heat exchangers, has become slime-like as a result of microorganisms growing there.
It is called. Compared to bathtubs, this `` yudoro '' is generated because the inside of the pipe is hard to clean, and sometimes it peels off partly and spills into the bathtub, which sometimes pollutes the bathtub water. Since the piping and the heat exchanger may be clogged, it is necessary to periodically clean the piping using a chemical such as sodium percarbonate.

れたものを含むものとする。In a bath water circulation system, the bath water circulation system comprises a bathtub, a bathing device having circulation means, connected to the bathtub by an outward pipe and a return pipe, and at least one part of a liquid contact part made of copper. A silver ion supply device for supplying silver ions to the outward pipe was provided. Thus, the silver ions generated by the silver ion supply device flow through the bath water device in a state close to the generated state before flowing out into the bathtub and diffusing and being diluted with bathtub water. Since the silver ion concentration immediately after the silver ion water supply device is high, a more effective microbial germicidal effect occurs, and it is possible to prevent the growth of microorganisms in the bath water equipment. Without using it, it is possible to prevent the generation of "hot water" for a long time. Further, in this case, the silver ions generated by the silver ion supply device come into contact with the copper member. Copper has a stronger ionization tendency in silver and copper, so when the generated silver ions come into contact with the copper member, the silver ions are no longer ions on the surface of the copper member and precipitate to form a coating of metallic silver or a silver compound. You. A very small amount of silver ions eluted from the silver compound coating causes a local microbial germicidal effect, which prevents the growth of microorganisms on the surface of the copper member. In addition, in this specification, "made of copper" shall include those made of either copper or a copper alloy.

着防止効果が向上する。When the liquid contact part is a heat exchanger of a water heater, the effect is more remarkably exhibited. In many cases, pipes of the heat exchanger are formed of a material mainly containing copper from the viewpoint of durability and heat conductivity. In this case, silver ions generated by the silver ion supply device come into contact with a heat exchanger pipe made of a material mainly containing copper. Thereafter, for the same reason as described above, it is possible to prevent the growth of microorganisms on the copper member surface of the pipe of the heat exchanger. In addition, the heat exchanger part is designed to be very large in order to efficiently conduct heat, and the immersion area of the piping inside the water heater is extremely large. The effect of preventing "hot water" adhesion is improved.

品交換やメンテナンスが容易に行える。More preferably, when the outward pipe is made of copper and the silver ion supply device is provided at the end of the outward pipe on the side of the bathtub, the silver ions generated by the silver ion supply device are mainly copper. Silver ions are also deposited on the surface of the copper member to form a silver compound film. The silver compound coating has a microbial germicidal effect, and can prevent the growth of microorganisms on the copper member surface of the pipe. Further, since the silver ion supply device is arranged near the bathtub, parts replacement and maintenance of the silver ion supply device can be easily performed.

At the time of bath water supply, water is guided from the water supply pipe 8 to the heat exchanger 7 by opening the bath water supply valve 16.

できる。At this time, in order to supply silver ions, a current is supplied between the electrodes of the electrolytic cell 6 while driving the circulation pump 3. Then, of the electrodes made of silver in the electrolytic cell 6, silver ions are dissolved from the positive electrode side and supplied into water. The silver ions are supplied to the electrolytic cell 6, the forward pipe 20,
The heat is guided to the heat exchanger 4 and the return pipe 21 in this order, and reaches the bathtub 1. At this time, since the outward pipe 20, the heat exchanger 4, and the return pipe 21 are made of copper, the silver ions that have come into contact with copper, which has a stronger ionization tendency, are removed from the copper pipe, the outward pipe 20, the heat exchanger 4, and the return pipe 21. Ion exchange occurs on each surface, and at the same time as copper is ionized, silver ions are no longer ions but are precipitated to form a film of metallic silver or a silver compound (silver chloride, silver oxide, etc.). Although these precipitated metallic silver or silver compounds are hardly soluble in water, silver ions are eluted in a very small amount (on the order of μg / L). The eluted silver ions have a local microbial germicidal effect, which prevents the growth of microorganisms on the surface of the copper member.

However, even if the pipe is made of resin or other metal, the effects of the present invention can be almost equally exhibited. . That is, the area of the liquid contact portion of the member that is in contact with water is designed to be extremely large in the heat exchanger 4 for the purpose of efficiently conducting heat. Is small. Therefore, even when the outward pipe 20 and the material are not copper, the silver coating is formed on the heat exchanger 4 occupying most of the liquid contact portion,
The effect of the present invention is hardly impaired.

The copper pipe used inside the bath water apparatus for purifying and sterilizing bath water by a circulation pump, a biological filtration tank, an ultraviolet lamp and a heater, which is called a “4 hour bath”, is also connected to the outward pipe 20. By disposing the electrolytic bath 6, a silver coating is formed on the copper member, and the effect of preventing the adhesion of the "hot water" is exhibited.

When a current of only 0.1 A is passed between the silver electrodes in the electrolytic cell 6 while circulating at a rate of 0.25 L / sec (= 0.25 L / sec), the efficiency of electrolysis (the amount of electricity flowing between the electrodes) home,
Assuming that the ratio of the amount used to generate silver ions) is 100% and the Faraday constant is 96500, the concentration of silver ions (atomic weight 107.9) flowing out of the electrolytic cell 6 is about 450 μg / L as in the following equation. Become. (0.1 × 107.9 / 96500 / 0.25) = 4.
47 × 10 −4 g / L = 447 μg / L The efficiency of electrolysis varies depending on the design of the electrolytic cell 6 and the water quality used, but according to our measurements, under any conditions,
It is generally in the range of 50 to 100%, and even if it is 50%, it is about 220 μg / L, which is a higher concentration than 50 to 200 μg / L, which is a concentration generally exerting a bactericidal effect. Is exhibited. When the current value is set higher than 0.1 A in the above example, or when the circulating flow rate is less than 15 L / min in the above example, the silver ion concentration can be made higher than in the above example.

That is, the water immediately after flowing out of the electrolytic bath 6 flows out of the bathtub 1 and diffuses and flows through the outgoing pipe 20 through the inside of the bath water circulation purification / warm-up device 50 without being diluted. Since the silver ion concentration immediately after the electrolytic cell 6 is high, a more effective microbial germicidal effect is produced even if a coating is not formed on the copper member, and the bath water equipment (in this case, the bath water circulation purification / warming device 50) is used. Microorganisms can be prevented from growing.
