Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a cold and hot water pine surge shower device that stimulates the skin and improves blood circulation by applying it to the human body, thereby producing 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, as a cold/hot water pine surge shower device of this type, as disclosed in Japanese Utility Model Application Publication No. 57-40392, tap water is supplied into a case, the impeller is rotated by the water pressure, and the impeller is rotated. By rotating the switching gear that meshes with the impeller shaft, the elongated holes drilled in it alternately align with the second outlet, creating a flow path that directly connects the tap water to the shower head, and a flow path that connects the tap water directly to the shower head. In some systems, cold water and hot water are alternately jetted from the shower head by being distributed alternately to the flow path communicating with the shower head through means for changing the temperature.

<Problems to be Solved by the Invention> However, in such a conventional cold/hot water pine surge shower device, the spouting cycle of cold water and hot water is determined by the water pressure of the tap water. When water is supplied to the water inlet, etc., the ejection cycle of cold water and hot water changes regardless of the user's request, and it is difficult to make subtle adjustments to the water pressure, so it is difficult to easily adjust the water pressure to meet the user's request. However, there is a problem in that it is not possible to finely adjust the ejection cycle of cold water and hot water, making it difficult to use.

The present invention has been made in view of the conventional circumstances, and an object of the present invention is to finely adjust the period of ejection of cold water and hot water with a simple operation while keeping the period of ejection of cold water and hot water constant.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems are as follows: a water inlet connected to a water supply source, a hot water inlet connected to a hot water supply source, and a hot water inlet connected to a shower head. An impeller connected to a motor is rotatably arranged between these three outlets, and the rotation of the impeller causes water to flow alternately between the water inlet and the hot water inlet. The motor is characterized in that it is provided with an adjustment section that communicates with the outlet and changes the amount of electricity supplied to the motor.

<Function> According to the technical means of the present invention, the rotational speed of the impeller is kept constant by the normal motor, the time for alternately communicating the water inlet and the hot water inlet with the inlet does not change, and the adjustment part By changing the rotational speed of the impeller by changing the rotational speed of the impeller, the length of time that the water inlet and the hot water inlet are alternately communicated with the inlet can be changed.

<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 connected to the water inlet 1b of the main body A via the water supply pipe D at a socket _G1 connected to the water supply side of the thermostatic mixing valve G, and the hot water source is connected to the water supply side of the thermostatic mixing valve G. The shower side water discharge part _G4 of the mixing valve G is connected to the hot water inlet 1a of the main body A via a water supply pipe.

The main body A consists of a substantially cylindrical valve case 1 containing a valve B 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 a hot water supply pipe C and a water inlet 1b connected to a water supply pipe D on its left and right sides, and an outlet _1c connected to a shower head E via a flexible hose E1 on its upper and lower surfaces. The escape ports 1d to which the pipes F connect are opened in a cross shape on the same plane, and the front side is closed, and a switching slider 3 formed in a cylindrical shape with a closed front side is provided inside.

The switching slider 3 has an outer diameter slightly smaller than the inner diameter of the valve case 1.
A groove 1e is provided inside the valve case 1 so as to be slidable in the front-rear direction, and a projection 3e extending in the axial direction is provided on the outer peripheral surface of the valve case 1.
A switching 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, and the lever 3f is manually operated in the front-rear direction. By doing so, the cylindrical portion 3g is configured to slide within the valve case 1 in the front-rear direction.

In addition, the switching slider 3 has a hot water hole 3a on the left side of the cylindrical portion 3g, and an outflow hole 3c on the top surface, and these hot water holes 3a and the hot water outflow hole 3c can be opened in the front and back directions by manually operating the switching lever 3f. They are formed in a long hole shape extending in the front and rear direction so that they are always in communication with the hot water inlet 1a and the hot water outlet 1c, respectively, even when the hot water is moved.
d respectively, and these water passage holes 3b and relief holes 3d
are formed into round holes so that they communicate with the water inlet 1b and the water outlet 1d, respectively, only when the switching lever 3f is pushed.

Furthermore, a rotatable valve B is provided inside the switching slider 3.

Therefore, when the switching lever 3f is pushed, the hot water inlets 1a, 1b, the outlet 1c, and the escape port 1 are closed.
d are all in communication via a rotatable valve B,
When the switching lever 3f is pulled, the hot water inlet 1a
Only the outlet 1c communicates with the outlet.

The valve B has an impeller B ₁ rotated by a motor B ₂ , and this impeller B ₁ is composed of two disks B ₁₁ whose diameter is slightly smaller than the inner diameter of the cylindrical portion 3g of the switching slider 3.
A blade plate B ₁₃ is provided between B ₁₂ , and in the installed state, the two discs B ₁₁ and B ₁₂ are connected to the hot water inlets 1a and 1.
b, are located front and rear so as to sandwich the outlet 1c and the relief port 1d.

The motor _B2 is arranged in the waterproof case 2 together with a reed switch _B21 that controls its operation, and by sliding the switching lever 3f, the magnet 3h provided at the rear end of the switching slider 3 approaches the reed switch _B21 . Only when this occurs, the impeller _B1 is rotated via a motor unit _B22 such as a reduction gear.

Further, the motor B ₂ has an adjustment part B ₂₃ that adjusts the rotation speed by changing the amount of current supplied to the motor B 2 , and the adjustment part B 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 battery B ₂₄ ,
The battery B 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 D connected to the water inlet 1b of the main body A connects its water supply side to the socket _G1 connected to the water supply source of the thermostatic mixing valve G, and connects one of the water supplies to the thermostatic mixing valve G. The section is branched to supply water to the main body A, and there is an opening/closing handle in the middle that opens and closes the flow path.
Set up D ₁ .

The thermostatic mixing valve G 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 _G2 that protrudes to the side. Switching handle that projects mixed water forward
G ₃ to shower side spout G ₄ or bath side spout
This is to selectively discharge water to _G5 .

Further, the relief pipe F connected to the relief port 1d extends downward through the rear of the thermostatic mixing valve G, 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 _G2 of the thermostatic mixing valve G to switch the mixed water to the desired temperature.
With G ₃ supplying water to the shower side water outlet G ₄ ,
When the switching lever 3f is pushed, first the motor B ₂
rotates, the impeller _B1 rotates, and the switching slider 3 switches the mixed water supplied to the hot water inlet 1a and the cold water supplied to the water inlet 1b through the hot water through hole 3a and the water through hole 3b, respectively. As the impeller B1 rotates, the outlet _1c flows through the outlet hole 3c and the relief hole 3d.
Alternatively, water is alternately supplied to either the outlet 1d, and hot water and cold water are alternately discharged from the shower head E connected to the outlet 1c and the relief pipe F connected to the outlet 1d, respectively.

Next, when the switching lever 3f is pulled, the rotation of the impeller _B1 stops and only the mixed water supplied from the hot water inlet 1a enters the switching slider 3 through the hot water through hole 3a, and constantly flows through the hot water outlet 3c. Water is supplied to the communicating outlet 1c, and only hot water is continuously spouted from the shower head E.

In the above embodiment, the main body A and the thermostatic mixing valve G were constructed separately and connected by the hot water supply pipe C and the water supply pipe D, but the present invention is not limited to this, and the two may be constructed integrally. Although the shower side spout _G5 of the thermostatic mixing valve G 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 may be directly connected to the hot water inlet 1a. It's okay.

Furthermore, in the embodiment described above, the relief port 1d for connecting the relief pipe F to the main body A is provided, but the relief port 1d may not necessarily be provided.

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

Normally, the rotation speed of the impeller by the motor is constant, and the time during which the water inlet and hot water inlet are alternately communicated with the inlet does not change, but the rotation speed of the impeller is changed by changing the rotation speed of the motor in the adjustment section. As a result, the length of time that the water inlet and the hot water inlet communicate with the outlet alternately changes in length, so it is possible to maintain the spout period of cold water and hot water constant while making subtle adjustments with simple operations.

Therefore, compared to conventional systems in which the spout period of cold water and hot water is determined by the magnitude of the water pressure of tap water, the spout period of cold water and hot water does not suddenly change regardless of the user's request, and the spout period of cold water and hot water does not suddenly change regardless of the user's request. It is easy to use and allows you to easily adjust the spouting cycle of cold and hot water according to your needs.
