And the outlet 12 can be alternately closed, and the jet flow can be intermittently sent to the bathtub 3. At this time, since the on-off valve 4 is incorporated in the pump housing box 5 of the pump 1, the workability can be improved and the maintainability can be improved. Further, by disposing the on-off valve 4 on the discharge side of the pump 1, it is possible to prevent the quality of the pump 1 from being impaired due to the occurrence of cavitation. Further, since the valve body 7 is axially supported by the projection 14 projecting from the inner wall of the valve accommodating portion 10 on the side opposite to the side connected to the rotary shaft 13 for rotationally driving the valve body 7, the valve body 7 is stably rotationally driven. it can.

[Embodiment] The on-off valve 4 is formed by including a valve casing 6 and a valve body 7 as shown in FIG. 1 (c). A valve accommodating portion 10 having a circular horizontal cross-sectional shape is formed in the valve casing 6, and an inlet side flow passage 8 and an outlet side flow passage 9 provided in the valve casing 6 are formed by an inlet 11 and an outlet 12. It communicates with the valve accommodating portion 10. An electromagnetic drive device 15 is provided above the valve casing 6 at the position of the valve accommodating portion 10, and the rotary shaft 1 that is rotationally driven by the electromagnetic drive device 15 is provided.
3 is arranged in the center of the valve accommodating portion 10. This rotating shaft 1
The valve body 7 is disposed in the valve housing portion 10 with the base end fixed to 3, and is rotated in one direction by the rotating shaft 13 in the valve housing portion 10. When the valve body 7 is driven to rotate, the valve body 7 alternately closes the inflow port 11 and the outflow port 12 to intermittently flow the jet flow. Further, a protrusion 14 is provided so as to project from the lower portion of the inner wall of the valve accommodating portion 10, and the lower portion of the valve body 7 is pivotally supported by the protrusion 14 to support the valve body 7 on the side opposite to the rotary shaft 13. . The on-off valve 4 configured as described above is arranged in the pump housing box 5 of the pump 1, and the pump 1 is communicated with the valve casing 6 via the inlet side flow passage 8. This pump 1 is a motor 1
6, the pump casing 17, and the impeller 18 are main components, and by driving the motor 16, the impeller 18 is rotationally driven via the motor shaft 19 so that the liquid sucked from the suction side flow passage 20 flows into the inlet side flow. The liquid is discharged to the passage 8. The pump housing box 5 housing this pump 1 is shown in FIG.
As shown in (a) and (b), they are arranged laterally of the bathtub 3 with a predetermined space therebetween, and the pump 1 and the bathtub 3 are connected by a connecting pipe 2. The bathtub 3 has a plurality of injection ports 21,
Around the bathtub 3, a distribution pipe 22 that distributes to each injection port 21
Is attached, and the distribution pipe 22 and the outlet side flow passage 9 are communicated with each other through the discharge side connection pipe 2a of the connection pipe 2. The suction-side connection pipe 2b of the connection pipe 2 connects the hot water inlet 23 at the bottom of the bath 3 and the suction-side flow passage 20. In the figure, reference numeral 24 is a drain plug, 25 is a jet flow switching knob, and 26 is a handle.

In the jet bath formed as described above, when the pump 1 is operated, the hot and cold water in the bathtub 3 is sucked from the suction side flow path 20 through the suction side connecting pipe 2b and the sucked hot and cold water is To eject as a jet jet from the injection port 21 through the pump casing 17, the inlet side flow passage 8 of the on-off valve 4, the valve housing portion 10, the outlet side flow passage 9 and the discharge side connecting pipe 2a and the distribution pipe 22. You can Then, the inflow port 11 and the outflow port 12 are alternately closed by the rotationally driven valve body 7 to intermittently stop the flow of hot and cold water to the ejection port 21, and to intermittently interrupt the jet jet ejected from the ejection port 21. Can be made. Specifically, the intermittent state is generated at intervals of 0.5 to 1 second. When the valve body 7 is rotationally driven, the lower portion of the valve body 7 is rotatably supported by the protrusions 14, so that the valve body 7 is stably and rotatably supported, and wear of the valve body 7 due to discharge pressure and a rotation shaft The instability of 13 can be prevented and a stable intermittent state can be obtained. The on-off valve 4 can be attached anywhere in the pipe, but if it is incorporated in the pump storage box body 5, no adverse effect occurs during maintenance or construction. That is, when the intermittent valve 4 is attached to the bathtub 3 side, maintenance cannot be performed, and when the intermittent valve 4 is attached in the middle of the connecting pipe 2, dust or damage may occur during construction, but inside the pump housing box 5 Incorporation into does not cause such an adverse effect. Further, when the intermittent valve 4 is attached to the discharge side of the pump 1, it is possible to make a complete intermittent state without deteriorating the quality of the pump 1. That is, on the suction side of the pump 1, the intermittent valve 4
In the case where the valve is attached, the quality of the pump 1 is impaired due to the occurrence of cavitation when the valve body 7 is shut off, and a complete intermittent state cannot be created.

[Effect of the Invention] As described above, the present invention incorporates the intermittent valve for continuing the jet flow into the pump housing box of the pump, which improves the maintainability of the intermittent valve and improves the workability. Since it is located on the discharge side of the pump, it is possible to prevent the occurrence of cavitation due to idle rotation of the pump that occurs when the intermittent valve is installed on the suction side of the pump, and to obtain a stable intermittent state without degrading the quality of the pump. Further, since the valve body is axially supported by the projection protruding from the inner wall of the valve accommodating portion on the side opposite to the side connected to the rotary shaft for rotationally driving the valve body by the intermittent valve, the valve body is Can be stably and rotatably supported, wear of the valve body and the shaft support of the rotating shaft can be stabilized, and a stable intermittent state can be obtained.
