[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bathtub for massaging by jetting a jet to a back or a foot or jetting shower water to a shoulder. The present invention relates to a channel switching valve device for a bathtub used for switching.

[0002]

2. Description of the Related Art Generally, in this type of bathtub apparatus, a foot nozzle is provided on a foot side of the bathtub, and a back nozzle is provided on a back side of the bathtub, so that a suction port of the bathtub communicates with a pump. In addition, the pump is communicated with a foot nozzle or a back nozzle via a switching valve device. By driving the pump and switching the switching valve device, a jet stream is jetted from the foot nozzle, a jet stream is jetted from the back nozzle,
Switching is performed such that a jet stream is jetted from both the foot nozzle and the back nozzle.

[0003]

In recent years, in this type of bathtub apparatus, in addition to the above configuration, a shoulder nozzle is provided on a flange on the back side of the bathtub, and shower water is directed from the shoulder nozzle toward the shoulder. There is also provided one that sprays to massage the shoulder, but in this case, bath water must also be supplied to the shoulder nozzle, and cannot be switched by the above-described switching valve device. Further, the switching valve device is designed to open and close by rotating a gate valve, but this type of valve has a leak. The jet sprayed from the foot nozzle or the back nozzle is in contact with the bath water in the bathtub, so that some leakage is allowed. However, the shower nozzle jets shower water, so no leak is allowed. Also, it is necessary to control the flow rate of shower water injected from the shoulder nozzle.

The present invention has been made in view of the above problems, and a first object of the present invention is to flow not only to a foot outlet and a back outlet, but also to a shoulder outlet. The bath can be switched with a single device even if the path can be switched and there is a shoulder nozzle, and there is no leakage from the shoulder nozzle, and the flow rate of the shower tub that can adjust the flow rate of shower water injected from the shoulder nozzle A second object of the present invention is to provide a path switching valve device, and to provide a sufficient massage feeling by ensuring a sufficient flow rate to be injected from a foot nozzle or a back nozzle. An object of the present invention is to provide a bathtub flow path switching valve device that can be made compact.

[0005]

In order to achieve the above object, the present invention provides a bathtub flow switching valve device in which an inflow port 2 is provided at a lower portion of a valve body 1 and a foot side of a bathtub 3 is provided on both left and right sides of the valve body 1. And a back discharge port 5 communicating with the back side of the bathtub 3, and the foot discharge port 4 and the back discharge port 5 are provided.
The valve body 1 is provided with a shoulder discharge port 7 communicating with the shoulder nozzle 6 of the bathtub 3 above the valve body 1, and the valve body 1 is opened and closed between the inflow port 2 and the foot discharge port 4 and the back discharge port 5. And a ball valve 9 that opens and closes between the inflow port 2 and the shoulder discharge port 7 is rotatably mounted in the valve body 1, and the gate valve 8 and the ball valve 9 are connected to each other. The ball valve 9 is connected to a valve shaft 11 which is connected and rotated by an operation knob 10.

It is also preferable that the foot outlet 4 and the back outlet 5 are provided in a vertically different manner.

[0007]

According to the above construction, by operating the operating knob 10 to rotate the valve shaft 11, the gate valve 8 and the ball valve 9 can be rotated. By rotating the gate valve 8, the opening and closing between the inflow port 2 and the foot discharge port 4 or the back discharge port 5 can be opened and closed. By rotating the ball valve 9, the inflow port 2 and the shoulder discharge port 7 can be opened and closed. Can be opened and closed between Thus, switching can be performed in three directions with one switching valve device A.
In addition, since switching between the inlet 2 and the discharge port 7 for the shoulder can be switched by the ball valve 9, there is no risk of leakage when the valve is closed. Further, by rotating the ball valve 9, the flow rate discharged from the shoulder discharge port 7 can be adjusted.

If the foot discharge port 4 and the back discharge port 5 are provided at different levels in the vertical direction, a sufficient opening size for the foot discharge port 4, the back discharge port 5 and the gate valve 8 is provided. Therefore, the flow rate discharged from the foot nozzle 13 and the back nozzle can be sufficiently ensured to give a sufficient massage feeling. The valve body 1 can be made compact by reducing its diameter while securing a sufficient flow rate.

FIG. 4A shows a state in which only the foot outlet 4 is open, and FIG. 4B shows a state in which both the foot outlet 4 and the back outlet 5 are open. FIG. 4D shows a state in which only the back discharge port 5 is open, and FIG. 4D shows a state in which only the shoulder discharge port 7 is open.

By the way, in order to give a bather a sufficient massage feeling in this kind of bathtub, it is necessary to secure a sufficient flow rate to the foot nozzle 13 and the back nozzle. It is necessary to make the flow path diameter of the outlet 4 and the back discharge port 5 sufficiently large, and to make the sizes of the openings 8a and 8b of the gate valve 8 sufficiently large. However, when the outlet port 4 for the foot and the outlet port 5 for the back are provided at the same level as in the embodiment of FIG. 3, if the diameter of the flow path is sufficiently large as described above, the diameter of the gate valve 8 becomes larger. As a result, the diameter of the valve body 1 increases, and the mounting position of the bathtub 3 on the flange 16 is limited. If the position of the outlet 4 for feet and the position of the outlet 5 for the back are made different in the vertical direction as in the embodiment of FIG. 1, the openings 8, 8b of the gate valve 8 can also be made different in the vertical direction. A sufficient opening can be formed in the outlet 4, the back discharge port 5, and the gate valve 8, and the valve body 1 can be made compact without increasing its diameter. When comparing FIG. 2A with FIG. 4A, the openings 8a and 8b of the gate valve 8 are shown.
Requires a certain area or more in order to secure the flow rate. However, when a valve structure as shown in FIG. 3 is provided, two openings 8a and 8b are provided on the same surface as shown in FIG. In addition, the diameter of the gate valve 8 increases. Therefore, when the openings 8a and 8b of the gate valve 8 are shifted up and down as shown in FIG.
Since a and 8b are not on the same plane, the diameter of the gate valve 8 does not need to be increased. Thereby, the diameter of the valve body 1 can be made compact without increasing the diameter.
