管２４より外部へ排出される。With the above configuration, when the hot water in the bathtub 11 is sucked from the suction port 12 by the operation of the pump 16 and discharged from the discharge pipe 15 by the operation of the pump 16, the hot water flows from the filtration inflow pipe 18 branched from the discharge pipe 15. It flows in, passes between the A and C ports of the three-way valve (a) 19, passes through the filtration device 20, passes through the filtration outflow pipe (a) 21, passes through the A and C ports of the three-way valve (b) 22, and passes through the filtration outflow pipe (b). At 23, it merges with the suction pipe 14 and is sucked again from the pump 16. At this time, the hot water in the bathtub passes through the filtration device 20 to filter the dirt of the hot water. That is, a filtration operation. In FIG. 1, if the dirt of the bathtub water is filtered, the inside of the filtration device 20 is clogged and the performance is deteriorated. Therefore, the inside of the filtration device 20 needs to be periodically cleaned, that is, a backwash operation. Therefore, as shown in FIG. 2, the three-way valve (a) 19 and the three-way valve (b) 23 are rotated by 180 ° to form a backwash water channel. That is, the hot water in the bathtub 11 that has passed through the filtration inflow pipe 18 from the discharge pipe 15 during operation of the pump 16 is filtered inflow because the A port side of the three-way valve (a) 19 is closed by the operation of the valve. The water flows through the backwashing inflow pipe 25 branched from the middle of the pipe 18, passes between the BC ports of the three-way valve (b) 22, and flows back into the filtration device 20 from the filtration outflow pipe (a) 21. At this time, the dirt accumulated in the filtration device 20 is discharged to the outside through the discharge pipe 24.

部に排出されてしまう問題があった。In such a conventional bubble bath apparatus, an air vent valve 26 for automatically removing air mixed in the filtration apparatus 20 is used for discharging dirt from the filtration apparatus 20 during the backwash operation. Dirt and filter media adhere to the air vent valve 26, causing clogging of the valve during use for a long time, causing water leakage. During the filtration operation, the hot water in the bathtub 11 is always discharged to the outside.
Even when the pump 16 is not used, when the water level in the bathtub 11 is higher than the filtration device 20, there is a problem that the bathtub water is discharged outside due to a siphon phenomenon.
