Description

[Detailed description of the invention] <Industrial application field> This invention uses a circulating pump to suck the water inside the bathtub to the outside of the bathtub, and then mixes air bubbles into the reflux water from the outside to form a jet jet inside the bathtub. The present invention relates to an operating section of a jet bath that allows water to be squirted.

<Prior Art> As shown in FIG. 2, a jet bath consists of a water intake pipe 31 and a discharge pipe 32, which are circulation paths, a main body unit 33, and an operating section 34.

Both the water suction pipe 31 and the discharge pipe 32 are connected to the bathtub 35. Of these, a jet nozzle 36 is provided at the return water outlet of the discharge pipe 32 for turning the return water into a jet jet containing air bubbles. This jet nozzle 36 sucks air by the discharge force of the reflux water and turns it into bubbles.

The main unit 33 includes a circulation pump 37 and a controller 38. Circulation pump 37
The water in the bathtub 35 is circulated through the water intake pipe 31 and the discharge pipe 32, which are circulation paths. The controller 38 takes in electrical signals from the water level detection switch 39, air switch 40, etc., and controls the operation of the circulation pump 37 based on these electrical signals.

The operating section 34 includes an air adjustment valve 41 and an operation switch 42. The air adjustment valve 41 is used to adjust the amount of air supplied to the jet nozzle 36, and the supplied air flows into the jet nozzle 36 from inside the valve through an air pipe 42 connected thereto. The operation switch 42 is used to control starting and stopping of the circulation pump 37, and has a bellows-like variable air chamber inside. An air pressure signal is output to 40 through air piping 43. The air switch 40 is the operation switch 42
The air pressure signal from the controller 38 is converted into an electrical signal and input to the controller 38.

This operation section 34 is provided near the bathtub 35 so that a bather can operate it in the bathroom, and usually controls the air adjustment valve 41 and operation switch 4.
2 is attached to the upper edge 35a of the bathtub 35.

<Problem to be solved by the invention> By the way, in the structure in which the air adjustment valve 41 and the operation switch 42 are provided on the upper edge 35a of the bathtub as described above, hot water may come into contact with the air adjustment valve 41 and the operation switch 42. , flow into their interior.

In the air regulating valve 41, the air supplied to the jet nozzle 36 is configured to circulate inside, so even if water flows into the interior, the water will be sucked out together with the circulating air. Although this does not cause any trouble, the inflow water accumulates inside the operation switch 42, and this may rot, emit a bad odor, or cause a malfunction.

To deal with this, a drain hole is provided at the bottom of the casing of the operation switch 42, and in this structure, inflow water flows out of the casing through the drain hole.

However, simply causing the inflow water to flow out from inside the operation switch 42 may cause problems with the bathroom structure, depending on the structure of the bathroom. That is, bathtub 3
5 and the washing area pan are integrated, and the bathtub 3
In a type of bathroom where there is no pan on the lower side of the bathroom, water droplets discharged from the water drain hole of the operation switch 42 fall directly onto the floor of the frame, causing a water leakage accident in the frame.

The present invention has been developed in view of the above-mentioned problems, and has a simple structure that allows water flowing into the operation switch to return to the bathtub without falling, thereby causing no inconvenience to the body. The goal is to prevent operation switch failures and the occurrence of bad odors.

<Means for Solving the Problems> In order to achieve the above problems, the present invention provides a circulation pump that circulates water in the bathtub through a circulation path consisting of a water suction pipe and a discharge pipe, and a circulation pump that circulates water back into the bathtub. It has a jet nozzle that mixes air to form a jet jet, an air adjustment valve that adjusts the amount of air supplied to the jet nozzle, and an operation switch that outputs an air pressure signal to control the operation of the circulation pump, The air adjustment valve and operation switch are the operating parts of the jet bath, which are attached to the upper edge of the bathtub.A drain hole is formed at the bottom of the casing of the operation switch, and this drain hole is connected to the air adjustment valve by a connecting pipe. It is configured so that it communicates with the air suction path.

<Operation> In the above configuration, when a jet jet containing air bubbles is ejected from the jet nozzle, air is sucked into the jet nozzle from the air regulating valve side, and this suction creates a negative pressure inside the air regulating valve.
This negative pressure acts on the drain hole of the operation switch via the connecting pipe. At this time, if water is flowing into the casing of the operating switch, the water is sucked out through the drain hole, flows into the air regulating valve through the connecting pipe, and returns into the bathtub via the jet nozzle.

<Example> Hereinafter, the present invention will be described in detail based on an example shown in the drawings.

FIG. 1 is a sectional view of an operating section of a jet bath according to an embodiment of the present invention.

As shown in the figure, the operation section includes the air adjustment valve 1.
The air regulating valve 1 and the operating switch 2 are attached to the upper edge 3 of the bathtub in parallel.

The air adjustment valve 1 is used to adjust the amount of air supplied to a jet nozzle (not shown). In this embodiment, the air adjustment valve 1 is a rotary operation type valve, and has a double-structured casing 4 and an operation knob 5. , rotating spool 6
and a presser ring 7.

The casing 4 has an air inflow gap 8 that opens upward between it and the operating knob 5 at the upper end, and an air outlet 9 at the bottom, and an air pipe 10 leading to the jet nozzle is connected to the outlet 9. ing.
In addition, a suction port 11 is provided at the bottom of the casing 4.
A connecting pipe 12 from the operation switch 2 is connected to this suction port 11.

The operating knob 5 and the rotary spool 6 are coaxially coupled, and the rotation angle is regulated by a stop pin 13 protruding from the shaft portion of the rotary spool 6. The rotating spool 6 has an air inflow hole 6a in the upper part that communicates with the space inside the casing 4,
An outflow hole 6b communicating with the air outflow port 9 of the casing 4 is formed in the lower part. Further, this rotary spool 6 is formed with a suction hole 6c that communicates with the suction port 11 of the casing 4. The presser ring 7 is provided around the shaft portion of the rotary spool 6, and has an air passage 7a opened in the vertical direction. Note that 14 is a gasket, and 15 is a fixing nut.

The operation switch 2 outputs a pneumatic signal by pressing and controlling the start and stop of a circulation pump (not shown), and includes a casing 16, a push button 17, a connecting rod 18, and a bellows 19.
and a presser ring 20.

An air pipe 21 is connected to the bottom of the casing 16, and a pneumatic signal is transmitted to an air switch (not shown) through the air pipe 21. A drain hole 22 is also formed at the bottom of the casing 16, and the connection pipe 1 through which the casing 4 of the air regulating valve 1 communicates is connected to the drain hole 22.
