問題がある。[0007] When the microfiltration filter 3 made of a hollow fiber membrane is clogged and the filter flow rate (membrane flow rate) decreases, the microfiltration filter 3 is washed as described above to recover the filter flow rate. However, the microfiltration filter 3 has a feature of having small holes and being small and soft, and thus is made of a hollow fiber membrane made of soft plastic or the like, and the hollow membrane thread becomes entangled or entangled by repeated washing. In addition, there is a problem that the cleaning of the microfiltration filter 3 becomes difficult, and the purification performance of the microfiltration filter 3 is reduced.

The bath water does not enter into the inside, and the purification is performed only by the hollow fiber membrane located on the outer peripheral side, so that the purification performance is reduced. Further, the inside cannot be washed, and the filter flow rate cannot be recovered sufficiently.

At the same time, the distal end of the microfiltration filter 3 on the side opposite to the secondary side is spirally wound and supported by the sewing thread 6, and the section from the secondary fixing end 7 of the microfiltration filter 3 to the distal end is formed. At least one or more outer peripheries are swingably supported. With such a configuration, when the microfiltration filter 3 made of a hollow fiber membrane is washed with bath water discharged from the nozzle 5, the filter from the collective fixing part 7 on the secondary side of the microfiltration filter 3 to the tip end is cleaned. Since at least one outer periphery of the section is swingably supported, the length of the hollow fiber membrane that can freely move is shortened, so that buckling deformation is difficult, and the impact force of the water flow during washing is reduced. It can prevent entanglement and entanglement of the hollow fiber membrane,
In addition, since the water can be swung, the bathtub water enters the inside of the microfiltration filter 3 with the flow of water at the time of washing, so that the hollow fiber membrane inside can be reliably washed. Bath water can be reliably contained and purified by the hollow fiber membrane inside.

Therefore, the length of the hollow fiber membrane that can freely move in the longitudinal direction is shortened, that is, the hollow fiber membrane is a section in which the section other than the swing support portion 6 can freely move in the longitudinal direction. Since the length in which the free movement in the longitudinal direction becomes shorter, buckling deformation is less likely to occur, and when the microfiltration filter 3 is washed in order to recover the filter flow rate (membrane flow rate), the hollow fiber membrane due to the impact force of the water flow is washed. Entangling and entanglement can be prevented, the life of the microfiltration filter 3 can be extended, and the life of the bathtub water purification device 1 can be extended, and the hollow fiber membrane has a swing support portion 6 in the longitudinal direction. Other than Since the space can freely move and swing, the water flow also flows through the hollow fiber membrane inside, and the dirt and attached matter can be effectively peeled off. Purification can be performed effectively even at the hollow fiber membrane portion, and the purification ability is not reduced.
