た。In such a conventional circulating purification device for a bath tub, since the jet by the jet line and the filtration by the filter line are simultaneously performed during bathing, the bathing time is short. In addition, when the degree of dirt is high, the purification time of dirty hot water is also shortened, and the system shifts to biological filtration without sufficient filtration. It has to be performed frequently and requires time and effort, and when the microbial filter medium 15 is extremely contaminated, insufficient regeneration occurs due to a shortage of air in the bubbling washing, and the life of the biological filtration means 16 is reduced. There was a problem that it became shorter.
