1) is a bathtub, (2) is a pump, and (3) is a circulation path that connects a water inlet (1a) provided in the bathtub (1) and a foam jetting nozzle (1b). And the pump (2) of the circulation path (3)
) The negative end of the first branch M path (4) is connected to the outlet, and the other end of the first branch path (4) is connected to the inlet side of the pump (2) as described later. The first branch (4) has a three-way valve (5) that acts as a circuit switching valve together with an electromagnetic on-off valve (9) to be described later.
and a filter (6) are interposed in this order. In addition, the filter (
6) is a container in which a support plate (6a) is provided and a spherical filter material (6b) such as glass beads is deposited on the support plate (6a). Moreover, the three-way valve (5) is used to switch between a state in which the first branch passage (4) is communicated with the other end side of the first branch passage (4) and a state in which the drain passage (7) side is communicated with each other. (8) is a second branch path connected in parallel with the first branch path (4), and one end of the second branch path (8) is connected to the circulation path (3) on the outlet side of the pump (2).
and the other end is connected to the first downstream side of the filter (6).
It communicates with the branch road (4). (9) is the electromagnetic on-off valve installed in the second branch (8), (10) is the drain channel (7)
The orifice (11) is an orifice for restricting the filtration flow rate provided between the confluence (A) of the first branch path (4) and the second branch path (8) and the filter (6). Orifice, (12
) is the confluence point (A), ! 1: An orifice for restricting the flow of the second branch path (8) provided between the second branch path (8) and the other end of the first branch path (4). In addition, the above-mentioned orifices (10), (11
), (12) are the drainage channel (7) first branch channel (4) second branch channel, respectively.
It is not necessary to restrict the flow rate by selecting the pipe diameter of the branch passage (8). (13) is a remote controller installed in the bathroom;
) has a filtration operation switch (14) and a backwash operation switch (
15) and a capacity selector switch (16). (17) is a controller installed in the main body (1), and the controller (
17) drives the pump (2) when the filtration operation switch (14) is turned on, and when the backwash operation switch (15) is turned on, the pump (2) is driven, the three-way valve (5) is switched, and the electromagnetic on-off valve is activated. (9), and open the capacity selector switch (1).
6) opens the electromagnetic on-off valve (9). In addition, the controller (17) has a built-in timer for accumulating the filtration operation time, and when the accumulated time (time a + b in Figure 2) reaches, for example, 30 minutes, the filtration operation is automatically switched to the backwash operation and the time is kept constant. After performing backwashing for a time of 0 minutes (for example, 2 minutes), the timer is cleared to return to filtration operation.

るのである。In the above configuration, when the filtration operation switch (14) is turned on when filtering the bathtub water, the three-way valve (5) is switched as shown by the solid line, and the pump (2) is driven. By driving the pump (2), some of the bath water flows into the circulation path (
3) to the first branch path (4) from the orifice (11), (1
2), the flow rate is restricted and flows through the first branch (4).
The bath water flowing through is filtered by a filter (6). At that time, if the filtration operation is waited for a set time, a backwash operation, which will be described later, is automatically executed during the filtration operation. Next, when cleaning the filter (6), press the backwash operation switch (15).
When turned on, the three-way solenoid valve (5) is switched to the state shown by the broken line, and the solenoid on-off valve (9) is opened. Then, a portion of the bath water flows through the second branch path (8), and a portion of the bath water that has reached the confluence point (A) flows in the opposite direction through the filter (6) to wash the filter medium (6b). , the washing water is discharged from the drainage channel (7).

強弱を制御できる。When the above-mentioned electromagnetic on-off valve (9) is opened during filtration using the capacity selector switch (16), the bath water flows through the first branch path (4).
At the same time, it also flows into the second branch path (8) and can reduce the flow rate reaching the bathtub (1).If a nozzle is provided at the bathtub outlet, the strength of the jet flow can be controlled by opening and closing this electromagnetic on-off valve. Can be controlled.
