Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a cold/warm water pine surge shower device that stimulates the skin by applying it to the human body, improves blood circulation, and provides a pine surge effect. The shower head alternately sprays cold water supplied from a hot water supply source and hot water supplied from a hot water supply source.

<Prior art> Conventionally, this type of cold/hot water pine surge shower device has been used, for example, as disclosed in Japanese Patent Application Laid-Open No. 50-101167, in the middle of a flow path from a water supply source to a water tank, and from a hot water source to a shower head. A valve is installed in the middle of the flow path that opens and closes depending on the water level in the tank, and hot water continues to be supplied to the shower head while cold water is being supplied to the tank, and when the water level in the tank reaches a predetermined position. At the same time, the drain valve installed at the bottom of the tank is opened to supply the cold water in the tank to the shower head. When the water level drops, the drain valve is closed and both valves are rotated to supply hot water to the shower head again.

Furthermore, as disclosed in Japanese Patent Publication No. 52-5368, for example, there is a device in which hot water is intermittently spouted by rotating a valve member using the force of a water flow.

<Problems to be Solved by the Invention> However, in the former case, with such a conventional cold/hot water pine surge shower device, only warm water can be continuously spouted by stopping the water supply to the water tank. However, there is a problem that only hot water cannot be spouted intermittently, and in the latter case, hot water and cold water cannot be spouted alternately, or hot water cannot be spouted continuously.

On the other hand, from the user's perspective, it has not only the function of discharging cold water and hot water alternately, but also the function of discharging only hot water intermittently and the function of discharging hot water continuously. It is desirable to select and use according to the purpose.

Therefore, the above request can be achieved by combining the former and the latter and providing valves at upstream positions, but there is a problem that the switching operation is complicated and difficult to operate.

In view of the conventional situation, the present invention aims to switch between alternate spouting of cold water and hot water, intermittent spouting of hot water, and continuous spouting of hot water with a simple operation.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to alternately spray cold water supplied from a water supply source and hot water supplied from a hot water supply source from the shower head. In the cold/hot water pine surge shower device, a water inlet communicating with the water supply source, a hot water inlet communicating with the hot water supply source, and an outlet communicating with the shower head are respectively opened in a radial manner, and a motor is connected between these three. A rotatable impeller is provided, and rotation of the impeller causes the water inlet and the hot water inlet to communicate with the outlet alternately, and a switching valve that opens and closes the water inlet, and a water supply source from the water inlet. The present invention is characterized in that it is provided with an on-off valve that manually opens and closes the flow path, and an operating lever that simultaneously controls the operation of this switching valve and the operation of the motor.

<Operation> According to the above-mentioned technical means, the present invention opens the on-off valve and manually operates the operating lever to open the switching valve and operate the motor, so that the impeller rotates and water flows from the water inlet. Cold water and hot water from the hot water inlet are alternately supplied from the outlet to the shower head, and by closing the on-off valve in this state, only hot water from the hot water inlet is supplied to the shower head intermittently as the impeller rotates. By manually operating the operating lever to close the switching valve and stop the motor, the impeller stops and only hot water from the hot water inlet is continuously supplied to the shower head.

<Example> An example of the present invention will be described below based on the drawings.

In this embodiment, as shown in Fig. 1, the water supply source is a socket _H1 connected to the water supply side of the thermostatic mixing valve H, which is connected to the water inlet 1b of the main body A via the water supply pipe E, and the hot water source is connected to the water supply side of the thermostatic mixing valve H. At the shower side water outlet _H4 of the thermostatic mixing valve H,
It communicates with the hot water inlet 1a of the main body A via a hot water supply pipe.

The main body A consists of a substantially cylindrical valve case 1 containing a switching valve B and a valve C, and a waterproof case 2, and the waterproof case 2 is integrally fixed so as to close the rear opening of the valve case 1.

The valve case 1 has a hot water inlet 1a connected to the hot water supply pipe D on its left and right sides, a water inlet _1b connected to the water supply pipe E on its left and right sides, and an outlet 1c connected to the shower head F via a flexible hose F1 on the upper and lower surfaces. The relief ports 1d to which the pipes G are connected are opened in a cross shape on the same plane, the front side is closed, and a switching valve B is provided inside.

In this embodiment, the switching valve B is constituted by a switching valve body 3 disposed inside the valve case 1 so as to be slidable in the front-rear direction.

The switching valve body 3 is formed into a cylindrical shape whose outer diameter is slightly smaller than the inner diameter of the valve case 1, and whose front face is closed. A protrusion 3e extending in the axial direction is provided on the outer peripheral surface of the switching valve body 3, and this protrusion 3e is connected to the valve case. 1. The control lever 3f is disposed in a non-rotatable manner by being fitted into a groove 1e formed in the inner peripheral surface of the valve case 1, and an operating lever 3f is provided at the center of the front surface of the valve case 1 so as to loosely fit through the front surface of the valve case 1 and protrude to the outside. By manually operating the lever 3f in the front-back direction, the cylindrical portion 3g is moved into the valve case 1.
It is designed to slide back and forth inside.

Further, the switching valve body 3 has a hot water hole 3a on the left side surface of the cylindrical portion 3g and an outflow hole 3c on the top surface, and these hot water hole 3a and the flow hole 3c are connected to the operating lever 3f.
They are formed in a long hole shape extending in the front and back direction so that even when the hot water inlet 1a and the hot water outlet 1c are moved in the back and forth direction by manual operation, both are always in communication with the hot water inlet 1a and the hot water outlet 1c, respectively.
A water passage hole 3b is provided on the right side, and a relief hole 3d is provided on the bottom surface.The water passage hole 3b and the extension hole 3d are closed to the water inlet 1 only when the operating lever 3f is pushed.
A round hole is formed so as to communicate with the opening 1d.

Furthermore, a rotatable valve C is provided inside the switching valve body 3.

Therefore, when the operating lever 3f is pressed, the switching valve B switches between the hot water inlets 1a, 1b and the outlet 1c.
The hot water inlet 1a and the hot water outlet 1d are all in communication via a rotatable valve C, and when the operating lever 3f is pulled, only the hot water inlet 1a and the hot water outlet 1c are in communication.

The valve C has an impeller C ₁ rotated by a motor C ₂ , and this impeller C ₁ is the cylindrical portion 3 of the switching valve body 3.
A vane plate C ₁₃ is provided between two discs C _{11 and} C ₁₂ whose diameter _is slightly smaller than the inner diameter. They are located in front and rear so as to sandwich the outlet 1c and the escape port 1d.

The motor _C2 is arranged in the waterproof case 2 together with a reed switch _C21 that controls its operation, and by pushing the operation lever 3f, a magnet 3h provided at the rear end of the switching valve body 3 approaches the reed switch _C21 . Only when this occurs, the impeller _C1 is rotated via a motor unit _C22 such as a reduction gear.

Further, the motor C ₂ has an adjustment part C ₂₃ that adjusts the number of rotations by changing the amount of energization, and the adjustment part C ₂₃ is provided so as to penetrate the side surface of the waterproof case 2 and protrude to the outside. In the example, the power source is a battery _C24 ,
The battery C ₂₄ can be replaced by opening one side of the waterproof case 2 and covering this opening 2a with a lid 2b so that it can be opened and closed.

On the other hand, the water supply pipe E connected to the water inlet 1b of the main body A connects its water supply side to the socket _H1 connected to the water supply side of the thermostatic mixing valve H, so that the water supplied to the thermostatic mixing valve H is connected to the socket H1. A part of the flow path is branched to supply water to the main body A, and an opening/closing handle _E1 is provided in the middle of the flow path to manually open and close the flow path.

The thermostatic mixing valve H has a conventionally well-known structure, and mixes the hot water supplied from the hot water source and the water supply source to a desired temperature by rotating the temperature adjustment handle _H2 that protrudes to the side. Switching handle _H3 that projects hot water forward
Shower side spout H ₄ or bath side spout H ₅
It selectively spews water to.

Further, the relief pipe G connected to the relief port 1d extends downward through the rear of the thermostatic mixing valve H, and is either left open as shown in the figure or connected directly to a drain pipe that communicates with the outside.

Therefore, such a shower device rotates the temperature adjustment handle _H2 of the thermostatic mixing valve H to switch the hot water mixed to the desired temperature.
_H3 supplies water to the shower side water outlet _H4 , and with the on-off valve _E1 of the water supply pipe E open,
When the operating lever 3f is pushed, the motor _C2 first rotates and the impeller _C1 rotates, and the hot water supplied to the hot water inlet 1a and the cold water supplied to the water inlet 1b are passed through the hot water through hole 3a, respectively. The water enters the switching valve body 3 through the water passage hole 3b, and flows into the outflow hole 3 as the impeller _C1 rotates.
Water is alternately supplied to either the outlet 1c or the outlet 1d through the outlet 1c and the outlet 1d, and hot water and cold water are alternately spouted from the shower head F connected to the outlet 1c. When hot water is spouting from the shower head F, cold water is spouted from the relief pipe G connected to the shower head F, and when cold water is spouting from the shower head F, hot water is spouted alternately and continuously.

Next, when the on-off valve _E1 of the water supply pipe E is manually closed in this alternating water spouting state, the water supply to the water inlet 1b is stopped, and only the hot water supplied from the hot water inlet 1a is supplied to the impeller _C1 . Outlet 3c as it rotates
Water is alternately supplied to either the outlet 1c or the outlet 1d via the escape hole 3d, and hot water is intermittently spouted from the shower head F.

Furthermore, when the operating lever 3f is pulled, the impeller _C1 stops rotating, and only the hot water supplied from the hot water inlet 1a enters the switching valve body 3 through the hot water through hole 3a.
Water is supplied through the outlet 3c to the outlet 1c which is always in communication, and only hot water is continuously discharged from the shower head F.

In the above-mentioned embodiment, the main body A and the thermostatic mixing valve H were constructed separately and connected by the hot water supply pipe D and the water supply pipe E, but the present invention is not limited to this, and both may be constructed in one piece. In addition, although the shower side spout _H5 of the thermostatic mixing valve H is connected to the hot water inlet 1a of the main body A, this is not limited to this, and the spout of a water heater such as a gas water heater can be directly connected to the hot water inlet 1a. You may do so.

Further, in the above-mentioned embodiment, the switching valve B is disposed inside the valve case 1 so as to be slidable in the front and rear directions, but the present invention is not limited thereto, and other structures may be used.
A relief port 1d was opened to connect the relief pipe G to the
In the case of a hot water storage type water heater, the escape port 1d does not necessarily have to be provided.

<Effects of the Invention> Since the present invention has the above configuration, it has the following advantages.

By opening the on-off valve and manually operating the operating lever to open the switching valve and operating the motor, the impeller rotates and cold water from the water inlet and hot water from the hot water inlet are alternately supplied from the outlet. By closing the on-off valve in this state, only hot water from the hot water inlet is intermittently supplied to the shower head as the impeller rotates, and by manually operating the control lever, the switching valve can be turned on and off. By closing the valve and stopping the motor, the impeller stops and only hot water from the hot water inlet is continuously supplied to the shower head, allowing for alternate spouting of cold and hot water, intermittent spouting of hot water, and continuous spouting of hot water. can be switched with a simple operation.

Therefore, different showers can be easily selected and used depending on the purpose, and are convenient to use.
