There are few places where hot spring water (hot spring water) is used to cover all of the bath water in hot spring facilities, and in many cases, mixed water in which hot water is mixed with hot spring water is used as bath water. . For example, it is customary to mix low temperature clean water with high temperature hot spring water to obtain an appropriate temperature mixed water, and supply the appropriate temperature mixed water into the bathtub for use as bathtub water.
[0003]
On the other hand, in a general bathhouse that does not use hot spring water, as a hot water mixed hot water supply device that supplies hot water and low temperature water mixedly, a high temperature water supply pipe for supplying high temperature water and low temperature water and a low temperature water supply respectively. Water supply pipes, hot and cold water mixing means such as a mixing valve for mixing high-temperature water and low-temperature water supplied by both pipes, and mixed water for supplying mixed water of an appropriate temperature mixed by the mixing means to the bathtub Many metal ones with a supply line are used.
[0004]
[Problems to be solved by the invention]
However, it is very difficult to employ the hot water / mixed hot water supply apparatus for a general bathhouse in a bathhouse of a hot spring facility.
[0005]
In other words, the hot spring water contains a variety of components such as iron, metals, sulfur, carbonic acid, etc., so the inside of the hot and cold water supply system is subject to early corrosion deterioration due to the influence of the components. This causes a problem that sufficient durability cannot be obtained. Furthermore, in hot spring water, a large amount of precipitates and precipitates are generated due to the contained components, and the deposits adhere to the inside of the apparatus, resulting in a decrease in the flow path diameter, making it impossible to obtain a predetermined performance. The problem occurs.
[0006]
This invention eliminates the above-mentioned problems of the prior art, prevents corrosion deterioration and deposit adhesion in the flow path, and can maintain sufficient performance for a long period of time, and can obtain sufficient durability. An object of the present invention is to provide a hot and cold water supply system.
[0007]
