Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a shower device that squirts hot water onto a human body.

<Prior art> Conventionally, this type of shower device can only continuously discharge either hot water or cold water set at a desired temperature with a temperature adjustment handle, etc., and is only used to wash the human body. It had no utility other than functionality.

Therefore, by spouting hot water from a shower intermittently and hitting the human body, or by alternately jetting hot and cold water from a shower and hitting the human body, it stimulates the skin and improves blood circulation, resulting in a pine surge effect. It is conceivable to make it possible to obtain it.

However, the former method has insufficient pine surge effect, and the latter method, when the water supply source is, for example, a gas instantaneous water heater, temporarily stops supplying hot water from the gas instantaneous water heater when cold water is jetted out. Because it stops,
The gas fire must be ignited every time the gas fire goes out and the hot water supply starts, and the gas ignition and extinguishing are repeated frequently, which is not energy efficient, and if the ignition is not done even once. There is a risk of accidents such as gas leaks and gas explosions.

<Problems to be Solved by the Invention> The problems to be solved by the present invention are that even if the water supply source is a gas instantaneous water heater, hot water and cold water can be jetted out alternately without repeatedly igniting and extinguishing the gas. It is to let

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to connect a hot water inlet for supplying hot water, a water inlet for supplying cold water, and an outlet communicating with the shower. In between, a valve is rotatably arranged to selectively communicate one of the two inlets with the outlet, and when the water inlet and the outlet communicate with each other, hot water supplied from the hot water inlet is directed to the outside. It is equipped with a relief channel for draining water.

<Function> The present invention allows hot water and cold water to be alternately spouted from the shower by selectively communicating the hot water inlet and the water inlet with the outlet via a rotatable valve.
When cold water is spouting from the shower, hot water is released and drained to the outside through the flow path, thereby continuously supplying hot water from the hot water source to the shower or the relief flow path.

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

As shown in FIG. 1, this embodiment shows a case where the shower side spout _G4 of the thermostatic mixing valve G is connected through the hot water supply pipe C of the hot water inlet 1a of the main body A.

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 E via a flexible hose E1 on its upper and lower surfaces. The inlets _F1 of the flow paths F are opened in a cross shape on the same plane, and the front side is closed, and a switching rider 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 1d is provided inside the valve case 1 so as to be slidable in the front-rear direction, and a protrusion 3d extending in the axial direction is provided on the outer circumferential surface of the valve case.
A switching lever 3e 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 3e can be manually operated rearward. By this,
The cylindrical portion 3f is adapted to slide within the valve case 1 in the front-back direction.

Further, the switching slider 3 has a hot water hole 3a on the left side of the cylindrical portion 3f and an outflow hole 3c on the top surface, and these hot water hole 3a and the hot water outflow hole 3c are opened in the front and back directions by manually operating the switching lever 3e. They are formed in a long hole shape extending in the front and back 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.
F ₂ are opened respectively, and these water passage hole 3b and relief hole F ₂ are opened respectively.
are formed into round holes so that they communicate with the water inlet 1b and the relief channel inlet _F1 , respectively, only when the switching lever 3e is pushed.

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

Therefore, when the switching lever 3e is pushed, the hot water inlets 1a, 1b, the outlet 1c, and the relief channel inlet _F1 are all communicated via the rotatable valve B, and when the switching lever 3e is pulled. In this state, only the hot water inlet 1a and the hot water outlet 1c communicate with each other.

In this embodiment, the valve B is a rotary blade _B1 rotated by a motor _B2 , and this rotary blade _B1 is composed of two disks _B11 and _B12 whose diameter is slightly smaller than the inner diameter of the cylindrical portion 3f of the switching slider 3. A slat B ₁₃ is installed between the
In the installed state, the two discs B ₁₁ and B ₁₂ are located front and back so as to sandwich the hot water inlets 1a, 1b, the outlet 1c, and the relief channel inlet _F1 .

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 3e, the magnet 3g provided at the rear end of the switching slider 3 approaches the reed switch _B21 . Only when this occurs, the rotary vane _B1 is rotated via a motor unit _B22 such as a reduction gear.

Further, _the motor B ₂ has an adjustment knob B ₂₃ for adjusting the number of rotations by changing the amount of current supplied to the motor B 2 . Now let's use battery _B24 as the power source,
The battery B ₂₄ can be replaced by opening one end surface of the waterproof case 2 and covering this opening 2a with a lid 2b so as to be openable and closable.

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 side of the thermostatic mixing valve G, and connects one of the water supplied 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 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, a relief pipe F3 is connected to the inlet _F1 of the relief flow path F, and the lower end _of the relief pipe _F3 extends downward through the rear of the thermostatic mixing valve G.
As shown in the figure, it can be left open as is, or it can be directly connected to a drain pipe (not shown) 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 3e is pushed, first the motor B ₂
rotates, the rotary vane _B1 rotates, and the hot water inlet 1a
The mixed water supplied to the water inlet port 1b and the cold water supplied to the water inlet port 1b enter the switching slider 3 through the hot water hole 3a and the water hole 3b, respectively, and as the rotating blade B1 rotates, the mixed water and the cold water supplied to the water inlet port 1b enter the switching slider ₃ through the hot water hole 3a and the water hole 3b. Water is alternately supplied to either the outlet _1c or the inlet _F1 of the outlet F1 through the relief hole F2, and hot water and cold water are alternately and continuously spouted from the shower E connected to the outlet 1c. From the relief pipe _F3 connected to the inlet _F1 of the relief flow path F, cold water is alternately supplied when hot water is being spouted from the shower E, and hot water is alternately supplied when the cold water is being spouted from the shower E. and spout water.

Next, when you pull the switching lever 3e, the rotating blade B ₁
The rotation of the slider 3 stops and only mixed water is supplied from the hot water inlet 1a through the hot water through hole 3a.
Water is supplied to the outlet 1c which is in continuous communication through the outlet 3c, and only hot water is continuously spouted from the shower E.

In the above-mentioned 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 both may be constructed in one piece. In addition, 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. You can also connect directly.

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

By selectively communicating the hot water inlet and water inlet to the outlet via a rotatable valve,
Since the shower alternately sprays hot and cold water, it stimulates the human skin more than conventional showers that spray hot water intermittently, improves blood circulation, increases the pine surge effect, and strengthens the skin. It has the effect of taking a shower to cleanse the body while strengthening the pine surge effect and skin at the same time.Furthermore, when cold water is spouting from the shower, hot water is released and drained to the outside through the flow path. Since hot water is continuously supplied from the hot water supply source to the shower or relief channel, even if the hot water supply source is a gas instantaneous water heater, the gas flame will not go out when cold water is spouted out and will remain lit. The shower can alternately spray hot and cold water.

Therefore, it is more efficient than a system that frequently repeats gas ignition and extinguishing, and there is no risk of accidents such as gas leakage or gas explosion.
