Further, the control panel 12 is connected to a hand switch 13 on which a hot water switch button 14, a washing switch button 15 and a stop switch button 16 are installed.

[0027] When the user depresses the washing switch button 15, the electric ball valve 8 is opened, and water or hot water from the hot water supply system flows through the water distribution pipe 3, and water pressure is applied by the pumps 17,18. Pumps 17 and 18 are installed to compensate for the shortage of water pressure, which is usually 2 bar.

When the water or hot water leaves the pump 17, it is divided into two paths, the water distribution pipe 3 and the bypass pipe 4, and in the bypass pipe 4, particles are supplied from the particle tank 10 into the bypass pipe 4 and particles are mixed. Water or warm water flows from the suction port 38 of the aspirator 11 into the interior of the aspirator 11.

On the other hand, in the water distribution pipe 3, water or hot water flowing in the water distribution pipe 3 enters the supply port 36 of the aspirator 11 and leaves the discharge port 37. In the pressure pump 11, pressure is reduced by the flow of water or hot water in the distribution pipe 3. The water or hot water mixed with particles from the bypass pipe 4 connected to the suction port 38 is sucked, mixed with the water or hot water from the water distribution pipe 3, and the particles from the outlet 37 of the aspirator 11. Water or hot water (hereinafter, referred to as particle mixed water) mixed with water is discharged, and the particle mixed water is supplied from the shower head 7 through the water distribution pipe 3. When the stop switch button 16 is pressed, the supply of the particle mixture water is stopped.

Omm, hard enough not to damage the skin, easily dissolved in water after use and harmless, for example, rice flour or rice flour, or water-soluble protein in which collagen is denatured It may be composed of gelatin or agar which is mucous substance from which red algae power such as eggplant is extracted. Also, the particles may contain a detergent component.

[0028] Therefore, when the user uses the particle mixture water supplied from the shower head, Since the child rubs on the skin surface, the blood circulation promoting effect by the massaging action can be obtained. Also, if particles containing detergent ingredients are used, in addition to the friction of the skin surface by the particles, the sebum and wrinkles present on the skin are dissolved and washed by the cleansing effect of the detergent ingredients. You can easily wash your body without having to do it at work. And when organic detergents of natural origin are used as detergent components, it will be superior to the skin, and those containing active ingredients such as moisturizers, fragrances, disinfectants and antibacterial agents will use moisturizers and aromas after washing. Fungal effects can be expected.

On the other hand, when normal water or hot water is used, pressing the hot water switch button 14 of the hand switch 13 opens the electric ball valve 8 as in the case of the washing switch button 15, and the hot water supply facility The water or hot water flows through the distribution pipe 3, water pressure is applied by the pumps 17, 18, passes through the aspirator 11, and normal water or hot water is discharged from the shower head 7. Also, when the stop switch button 16 is pressed, the supply of water or hot water is stopped.

Here, a control method of the motor-driven ball valve, the pump, and the particle supply unit will be described with reference to FIG.

Fig. 2 is a table showing the power on / off of the electric ball valve, the pump and the particle supply unit.

FIG. 5 is a conceptual view showing the internal structure of the aspirator of the shower apparatus according to the first embodiment of the present invention.

In FIG. 5, the aspirator 11 is a double-sided type having a supply port 36, an outlet 37, and a suction port 38. A water pipe is connected to the inlet 36 and the outlet 37, and a bypass pipe is connected to the suction port 38. Ru. A divergent nozzle 40 is installed inside the aspirator 11 on the side of the supply port 36 and on the side of the tapered nozzle 39 1S outlet 37. In the present application, the tapered nozzle 39 has a shape in which the cross-sectional area decreases along the axis, while the divergent nozzle 40 first decreases in cross-sectional area along the axis and then increases. It means the one with the following shape.

In the aspirator 11, the flow of water or hot water flowing from the supply port 36 causes Then, the suction force acts on the suction port 38. However, by installing the tapered nozzle 39, the dynamic pressure of the water or hot water from the water distribution pipe becomes high, and the flow velocity becomes high, and Since the internal pressure is further reduced, the suction force of the suction port 38 is increased, and as a result, water or hot water mixed with particles from the bypass pipe connected to the suction port 38 is strongly sucked into the evaporator 11. I can.

On the other hand, in the divergent nozzle 40, a bypass pipe force sucked from the suction port 38 forms a water or hot water flow path mixed with particles in the open portion of the tip, and a tapered divergent nozzle in the divergent portion at the rear. The dynamic pressure increased by 39 is reduced to return to the normal flow velocity, and water is conducted to the outlet 37.

In addition, the suction port 38 may be disposed at a lower pressure position in order to apply a strong suction force. Specifically, as shown in FIG. 5, it is preferable to install at a position closer to the supply port 36 than the position of the outlet of the tapered nozzle 39 indicated by the dotted line and the reference numeral B.

Furthermore, the outlet diameter d of the tapered nozzle 39 should be smaller than the throat diameter d of the diverging nozzle 40

The agitator 42 is configured to operate.

Further, when the main shaft 43a and the screw 21 are connected, the main shaft 43a and the screw 21 may be connected by combining two or more gears having different sizes necessarily using the power transmission band 45. In this case, it is necessary to set the diameter of the gear so that the stirrer 43 b and the screw 21 do not interfere with each other.

In addition, the particle stirring mechanism for stirring particles 35 in hopper 20 prevents sticking of particles 35 in hopper 20 and smooths the supply to screw 21 without being limited to the configuration shown in FIG. If it is a thing, the shape of the stirring body 42 and its drive method do not make it a problem. That is, depending on the nature of the particles 35 used, for example, the particle shape and fluidity of the particles 35 The shape and driving method of the stirrer 42 may be changed as appropriate. For example, another power unit may be provided to operate the stirrer 42.

As described above, in the shower apparatus la according to the present embodiment, by providing the particle stirring mechanism in the hopper 20, the particles 35 introduced from the direction indicated by the symbol C in FIG. Control the amount of particles 35 fed in the direction shown by the symbol E in the drawing to a constant or high accuracy in the particle supply piping 22 because it slides down to the screw 21 without interruption. It is possible.

[2] Hereinafter, a shower apparatus according to a second embodiment of the present invention will be described based on FIGS. (Especially, it corresponds to claim 1, claim 2, claim 4 to claim 8.)

The end 22a and the opening 49 do not allow the particles 35 to scatter to the outside. ,.

Then, in the connection portion 48, the noise path pipe 4 is connected to the particle receiving portion 46, and the particles 35 supplied from the particle supply pipe 22 are mixed with water or warm water 34 flowing from the bypass pipe 4 through the orifice 33. The suction port 38 sucks the gas into the aspirator 11. At this time, it is desirable that the particle supply pipe 22 be disposed above the connection portion 48 of the particle receiving portion 46 and the bypass pipe 4.

As described above, when the particle supply pipe 22 is disposed above the connection portion 48, the particles 35 supplied from the particle supply pipe 22 are not properly mixed with the air in the particle receiving portion 46. There is no risk of clogging in the end 22a of the particle supply pipe 22 or in the particle receiving portion 46 because it falls freely toward the portion 48!

Further, at this time, the air in the particle receiving portion 46 is ventilated through the gap G, and therefore, the moisture of the water supplied from the bypass pipe 4 or the moisture of the hot water 34 does not clog and clog the particles 35.
