Since only the physical filtration tank is circulated for filtration, the load is smaller and the flow rate on the filtration side is smaller than in the conventional example in which both physical filtration and biological filtration are performed when performing simultaneous filtration during jet injection operation. A large number of large particles such as dirt can be effectively physically filtered to prevent inclusion of dirt in the jet flow during jet injection. Filtration When performing both filtrations, the intermittent valve is closed, only the circulation pump is operated, the second three-way valve is switched, and the first on-off valve is opened, so that the hot and cold water in the bathtub sucked from the suction port is closed. It can flow through the jet injection flow path to the circulation flow path, filter the hot water in the order of the physical filtration tank and the biological filtration tank, and return it from the spout to the inside of the bath via the jet injection flow path to maintain the quality of the hot water. Yes, and when performing only filtration using the biological filtration tank, close the intermittent valve, operate only the circulation pump, switch the first 3-way valve and the second 3-way valve, and open the first on-off valve. By opening, the hot and cold water of the bathtub sucked from the suction port flows through the jet injection flow path to the circulation flow path, and the first three-way valve causes the first bypass flow path, the second bypass flow path, and the first opening / closing valve. Flow through the biological filtration tank, perform biological filtration, and then pass through the jet injection flow path. Those capable of retaining water is returned to the bath from the water discharge port.
