Description of the Related Art Conventionally, both ends of a circulation channel are connected to a suction port and a water outlet provided in a bath, and a circulation pump, a sand filtration tank, and a biological filtration tank are arranged in the middle of the circulation channel,
The hot water in the bathtub is circulated through the circulation flow path by the circulation pump and returned to the bathtub again, and when passing through the circulation flow path, the hot and cold water in the bathtub is filtered by the sand filtration tank and the biological filtration tank provided on the way. It is known that the bath can be bathed for a long time by returning it to the bathtub again.

別途必要とするという問題があった。However, in the above-mentioned conventional example, only the hot water in the bathtub is purified by simply circulating the hot water in the bathtub in the circulation passage and returning it to the bathtub. Therefore, in the conventional case, there is a problem that in order to inject the jet water into the bathtub, the jet water injection flow passage must be provided separately from the circulation flow passage. There is a problem that a suction port and a spout are required separately.
