2. Description of the Related Art Generally, in this type of bathtub apparatus, a foot nozzle 2 is provided on the foot side of the bathtub 1 as shown in FIG.
Is provided with a back nozzle 3 on the back side of the tank, and the hot water inlet 4 of the bathtub 1 and the pump 5 are communicated with each other. The pump 5, the foot nozzle 2, and the back nozzle 3 are switched via the valve device A. It is in communication. Then, by driving the pump 5 to switch the switching valve device A, a jet flow is jetted from the foot nozzle 2, jetted from the back nozzle 3, or jetted from both the foot nozzle 2 and the back nozzle 3. It can be switched as you like.

This switching valve device A is constructed as shown in FIGS. An inflow port 8 communicating with the pump 5 is provided at a lower portion of the valve body 7, and a foot discharge port 9 communicating with the foot nozzle 2 and a spine communicating with the back nozzle 3 are provided on both left and right sides of the valve body 7. And a discharge port 10 are provided. Valve body 7
Inside the valve body 11 is rotatably installed, and the inflow port 8
The valve portion 13 of the valve body 11 is located in the valve chamber 12 between the foot outlet 9 and the back outlet 10. The valve shaft 14 of the valve body 11 is projected upward from the valve body 7, and
An operation knob 15 is integrally attached to the upper end of the. Then, when the operation knob 15 is operated to rotate the valve portion 13, the inflow port 8 and the foot discharge port 9 are communicated with each other, the inflow port 8 and the back discharge port 10 are communicated with each other, and the inflow port 8 and Both the foot outlet 9 and the back outlet 10 can be communicated with each other.

[0004]

By the way, in recent years, there has been provided a bathtub in which a shoulder shower device is mounted on the flange of the bathtub and shower water is sprayed onto the shoulder to massage the shoulder. There is. However, in the conventional switching valve device A, the foot outlet 9 and the back outlet 1 are provided.
It was possible to switch only to 0, and one switching valve device A could not switch to the shoulder shower device to supply hot water.

The present invention has been made in view of the above problems, and an object of the present invention is to switch the flow passage not only to the foot outlet and the back outlet but also to the shoulder outlet. It is an object of the present invention to provide a flow path switching valve device for a bathtub which can be switched by one device even if there is a shoulder shower device.

[0006]

In order to achieve the above object, a flow path switching valve device A for a bath according to the present invention is provided with an inflow port 8 at a lower portion of a valve body 7 and the legs of the bath are provided on both left and right sides of the valve body 7. A foot outlet 9 communicating with the side and a back outlet 10 communicating with the back side of the bathtub are provided, and the valve body 7 for the shoulder of the bathtub is provided above the foot outlet 9 and the back outlet 10. A shoulder discharge port 16 communicating with the shower device is provided, and a valve body 11 for switching a flow path is internally provided in the valve body 7 so as to be rotatable and vertically movable.

[0007]

According to the above structure, the valve body 11 is moved up and down,
By rotating the valve body 11,
The foot outlet 9, the back outlet 10 to the shoulder outlet 16 can be freely communicated with each other, and one switching valve device A
Can be switched to 3 directions.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an inflow port 8 is provided at the bottom of a valve body 7, and foot outlets 9 are provided on both left and right sides of the valve body 7.
And a back discharge port 10, and a shoulder discharge port 16 is provided above the back discharge port 10. Inside the valve body 7, a valve body 11 is rotatably and vertically movable. Disc 1
Reference numeral 1 is composed of a valve portion 13, a valve shaft 14 and a cylinder portion 17. Three upper and lower O-ring grooves 18a, 18b, 18c are provided on the inner surface of the upper portion of the valve body 7, and the upper O-ring 19 on the upper portion of the valve portion 13 is engaged with the O-ring grooves 18a, 18b, 18c. I'm supposed to get it. Three O-ring grooves 20a, 20b, 2 are formed above and below the inner surface of the lower portion of the valve body 7.
0c is provided, and the lower O-ring 21 at the bottom of the tubular portion 17
Can be engaged with the O-ring grooves 20a, 20b, 20c. A valve body retainer 22 is mounted on the upper portion of the valve body 7, and the valve shaft 14 is inserted through the valve body retainer 22. An O-ring groove 23 is provided on the inner periphery of the valve retainer 22, and a plurality of O-rings 24 are provided on the outer periphery of the valve shaft 14 in the vertical direction.

When the valve body 11 is located at the lowermost position and the valve body 11 is rotated, the inflow port 8 and the foot discharge port 9 to the back discharge port 10 can be connected to each other, or can be switched to both of them. it can. Upper O is formed in the middle O-ring grooves 18b and 20b.
When the ring 19 and the lower O-ring 21 are fitted, the valve body 11 is positioned in the center, and the valve body 11 is rotated, the inlet 8
And foot outlet 9, back outlet 10 and shoulder outlet 16
Can be switched to communicate with all of the above, or can be communicated with only the foot outlet 9 and both the back outlet 10 and the shoulder outlet 16. Further, when the upper O-ring 19 and the lower O-ring 21 are fitted into the uppermost O-ring groove 18a and the O-ring groove 20a, the valve body 11 is positioned at the uppermost position, and the valve body 11 is rotated, the inlet 8 is formed. The communication of the shoulder outlet 16 can be opened and closed, and the flow rate can be adjusted.

[0010]

As described above, the present invention is provided with an inflow port at the lower portion of the valve body, and a foot discharge port communicating with the foot side of the bathtub on both left and right sides of the valve body, and a back port communicating with the back side of the bathtub. A discharge port is provided, and a shoulder discharge port communicating with the shoulder shower device of the bathtub is provided in the valve body above the foot discharge port and the back discharge port, and the valve body for switching the flow path is rotated in the valve body. Since it is freely and vertically movable, the valve body can be moved up and down and the valve body can be rotated to separate the inlet port from the outlet port for the foot, the outlet port for the back, and the outlet port for the shoulder. It can be freely communicated, and can be switched in three directions by one switching valve device, and one switching valve device can be applied to a bathtub having a foot nozzle, a back nozzle, and a shoulder shower device. .
