[Prior art and its problems]

 In the case of baths that cannot be re-cooked, in order to raise the temperature of the bath, the water is drained and then the bath is adjusted to adjust the temperature, and especially when the interval between baths is long, bath water is wasted. There was a problem of doing it.

[0003] In addition, when artificial or natural hot spring water or mineral spring water is used as bath water, depending on its composition, it may damage the kettle of the hot water device and cannot be used. In particular, when enjoying a natural hot spring in a bathtub equipped with a home hot water system, it is possible to inject heated hot spring water and enter the area while it is not cooled, but heat it and reuse it. I couldn't do it and had to drain it.

[0004] Furthermore, the bathtub water circulation heating device as a conventional device ranges from a large-scale device to be installed at any place outside the bathtub by facility construction to a simple and convenient device to be attached to the edge of a household bathtub. However, there was no one that was designed to easily release hot spring water in a home bathtub in a natural outflow manner, and that it had a simple structure for easy disassembly and assembly. In particular, when natural hot spring water is used, various mineral components precipitate out of the hot spring water over a long period of use and adhere to or settle in the container, making it easy to disassemble and clean. Is also an important requirement.
