Description

[Detailed description of the invention] This invention relates to showers.

When attempting to impart a massage effect to a shower for the purpose of washing the body, conventional showers have the following drawbacks.

That is, if the pump is of the type 4 type with an output of about 100 W or less, the necessary flow rate and pressure cannot be obtained and a massage effect cannot be expected. Therefore, by incorporating an automatic opening/closing device into a small pump that sprays fluid radially to turn the water wheel and open and close the flow path using the rotational movement, the intermittent flow of water provides a sensory effect, but the pressure is weak, so it has a massage effect. I can't expect too much. On the other hand, large size (output 200W
Motor pumps (about the above) are difficult for users to use and are expensive at the time of purchase, so there are few benefits. Therefore, an object of the present invention is to provide a shower that can provide a sufficient massage effect using a 4-type pump.

A first embodiment of the invention is shown in FIGS. 1 to 3.

That is, this shower is provided with an intermittent opening/closing valve 3 and a surge tank 4 between a shower head 1 and a pressurizing pump 2. 5 is a connection hose, 6 is a storage tank, 7
1 is a container containing a pump 2, a valve 3, and a surge tank 4, 8 is a water suction hose, 9 is a step-down insulation transformer, 1 is a river plug, 11 is a power cord, 12 is a floor, 13 is a wall, 1
4 is a pillar.

The valve 3 is intermittently opened and closed using a solenoid valve, a water pressure valve, or the like.

Further, as shown in FIG. 4, the surge tank 4 has a pressure receiving plate 17 slidably disposed inside a rigid tank body 16 in which a through hole 15 is formed, and is attached by a coil spring 19 in the direction of the water inlet/outlet 18. It was a strong force. Pump 2 is a well cascade pump with an output of 100W. This shower is used by operating the pump 2 with the water inlet of the water suction hose 8 attached to the hot water storage tank 6, and by opening and closing the valve 3 intermittently.

In this case, when the valve 3 is open, pressure water flows into the shower head 1 through the connecting hose 5 and is radiated as a shower. Furthermore, when the valve 3 is closed, the water supply pressure of the pump 2 pushes the pressure receiving plate 17 against the spring force of the coil spring 19 of the surge tank 4, and moves to the pressure equalization position. Water is stored under pressure in the inner space. Then, when the valve 3 opens, the spring force stored in the coil spring 19 supplies the accumulated pressure water to the shower head 1, and at the same time, the pump 2 supplies the water to the shower head 1. As a result, the strength of the water coming out of the shower head 1 shows a pattern as shown in Figure 5, and the peak value is stronger than that with the 200W pump, and as a result, you can feel it This means that you are getting something comparable to a pump.

Moreover, when this pattern is compared with the pattern of the strength of acupressure as shown in FIG. 6 in acupressure massage, it can be said that the acupressure effect can be produced since they are similar. In addition, Figures 7 and 8 show the types and configurations of the shower head 1. 2 holes are narrow holes used when you want a shower massage as soft as a normal shower, and 21 holes are coarse and wide. The medium hole is used when you want to give a shower massage, 22 is the aperture hole that is used when you want to perform intensive local massage such as spit massage, 23 is the normal shower hole, 24 is the aperture hole, and 25 is a wide and intensive hole. It is a spatula-shaped aperture hole for when you want to massage. A second embodiment of the invention is shown in FIG.

That is, in this shower, the surge tank 4a is made of an elastic body such as rubber, and the surge output is extracted by the elasticity of the rubber. The rest is the same as the first embodiment. A third embodiment of the invention is shown in FIG.

That is, in this shower, the surge tank 4b has a bellows structure made of synthetic resin or metal, and the surge output is obtained by the elasticity of the contraction. The rest is the same as the first embodiment. As described above, the shower of the present invention has the effect that a massage effect can be obtained because the surge tank is inserted between the pump and the shower head and this is controlled by the intermittent control pulp.
