Description

[Detailed explanation of the invention] When washing the body in a bath, bathhouse, etc., one usually applies soap to a sponge, towel, etc., lathers it up, rubs the body, and then washes the body with a shower. Everyone agrees that when these movements become tiring, it becomes a considerable burden and often makes bathing a chore. If people can perform these series of movements using small amounts of power, they can eliminate fatigue.
You can fully enjoy the original purpose of the bathroom, which is to wash away dirt and grime.

To solve this problem, we devised a shower device that uses water wheel power. To explain this with the help of a diagram, the shower equipment main body 1 has a guide ben 3 provided inside.
Inside, a water wheel 4 having blades 5 is rotatably supported by a bearing 7 attached to the main body 1 (also serving as a liner ring) and a bearing 8 attached to a cover 2 assembled integrally with the main body 1. This water wheel 4 is rotated by the water flow from the inlet A, and a water discharge hole 12 is provided on the outer plate of the impeller outlet of the water wheel 4, and soap and soap are provided on the outer periphery of the outer plate.
A fitting 9 such as a sponge or brush is inserted so as to be able to slide in the axial direction and rotate together with the outer plate, and the fitting 9 is provided with a hole 14 that opens and closes the water discharge hole 12 by sliding, and The porous plate 6 for spouting hot water and water is integrated with the outer plate 4 (or the fitting 9) so as to block the waterway on the water turbine outlet side to form a mounting rotary plate, and the tip of the fitting 9 is shown in Fig. 1. If you attach a ring-shaped soap 10, sponge 11, brush, etc. to your body, just by lightly pressing the device against your body, the soap 10, sponge 11, or brush, etc. will rotate, lather, and clean dirt automatically, making it easy to use by hand. All you have to do is move the device to each part of your body. When the device is removed from the body, only the shower works, and at the same time as the cleaning action is performed, the perforated plate 6 rotates and spouts water, so the water droplets from the shower sequentially rotate and move the point of impact on the body, providing stimulation. There is also this effect.
When pressed, the sponge 11 or brush scrubs the body, so the person can enjoy a comfortable bath without feeling burdened by conventional movements.
In order to make soap and the like easy to replace as consumables, they are attached to the fixture 9 using a spring action so that they can be attached and detached and that they do not spin freely.

Now, if we consider the case where we use domestic water supply as a power source, the water source usually has an energy of ^about 20l/min x 2Kgf/cm2, and the type of water wheel is the comparative rotation speed n _s = 1600/H1/ 2=1600/(20)1/2≒358
Therefore, Francis-type water turbines or propeller-type water turbines fall into this range. When considering the water discharge hole 12, pressure regulation valve 13, etc., which will be described later, a Francis type water turbine is most suitable for its structure. First, to explain the case where the pressure regulating valve 13 is used to simultaneously use the shower, brush, sponge, etc., if the pressure required for the shower to blow out from the pore plate 6 is about 1 Kgf/cm ² , it will be enough to rotate the water wheel. Available energy is 20l/min×
1Kgf/ ^cm2 , water horsepower approximately 0.044PS, water turbine efficiency 20
~30%, output 0.009~0.013PS, water turbine outer diameter 4
cm, rotation speed 600rpm, torque 0.011~0.016Kg
It becomes a water wheel of about f-m and generates enough torque to rotate brushes, sponges, etc. and scrub the body. If the specified pressure of the pressure regulating valve is set low, the output of the water turbine increases and the amount of shower water decreases, and if it is set high, the reverse is true, and by changing the setting, the output of the water turbine can be adjusted. In addition, since the Francis type water turbine can fill the impeller outlet side with water, it can be used at the same time as a shower by attaching a perforated plate 6 to the end of the outer plate so as to block the waterway on the water turbine outlet side. I can do it.

Next, the case where the water discharge hole 12 is provided will be described.
Press a sponge or the like strongly against your body and slide the fitting 9 between the hole 14 of the fitting 9 and the water release hole 12 of the outer plate.
If the total amount of water from the blade outlet is discharged from the hole 14, the amount of shower water will be small, and almost all the energy of the water source will be used to rotate the water wheel, which will generate a strong rotational torque.

Furthermore, the shower device of the present invention fills the annular passage formed by the outer periphery of the fitting 9 and the cylindrical portion of the shower device main body 1 with water released from the hole 14 or the pressure regulation valve 13 and allows the water to flow gradually. It has a structure that reduces the discharge velocity loss by increasing the total efficiency and increases the output of the water turbine. Of course, a larger and more powerful type than the calculation example above is used when using both hot and cold water (using two faucets), or when using in a bathhouse with abundant water volume and water pressure, such as a hotel or hot spring spa. Another effect of the pressure regulating valve is that when soap or the like is cylindrical without a notch, when it is lightly pressed against the body, the hot water or hot water ejected from the pore plate 6 is trapped inside the cylinder, reducing the output of the water turbine. Therefore, the pressure on the water turbine outlet side is a constant pressure (for example, 1 kgf/
By setting the pressure regulating valve 13 so that the pressure does not exceed cm ² ), a decrease in output can be prevented and constant control of the water turbine output can be achieved.

In addition, in the case of the water discharge type from the water discharge hole 12, if the force of pressing the soap, sponge, etc. against the body is increased and the entire amount is discharged, the water turbine output will be maximum and the amount of shower water from the hole plate 6 will almost disappear. The amount of soap lathering will increase, and if the pressing force against the body is reduced to release a small amount, the output of the water wheel will decrease, the amount of shower water will increase, and the amount of lather will decrease.

A spring may be provided between the shower device main body 1 and the fixture 9, and the relationship between the pressing force and the opening degree of the hole 14 can be easily changed depending on the strength of the spring.

Further, in combination with the pressure regulation valve 13, the maximum value of the shower water amount can be regulated.

Whether the water discharge hole 12 and the pressure regulating valve 13 are installed together or separately is selected depending on the purpose.

As mentioned above, the user can select the device according to the purpose and control the amount of foam, amount of shower, rotational torque, strength of pressing force, rotational speed, etc. by adjusting the settings according to the user's preference. Able to operate equipment and achieve the purpose of bathing.

You can also use a brush (or a sponge 11 or a rubber ring or a ring-shaped array of resin balls) without using soap.
Types equipped with only the above can be used exclusively for pine surgery and shaving, as well as for fatigue recovery and beauty treatment, so these types can be selected depending on the purpose and specifications.

As explained above, unlike the devices that simply squirt soap, the proposed device has a built-in water wheel and uses the water flow and pressure of the shower to rotate brushes, sponges, soap, etc. By controlling the output by adjusting the pressing force and automatically switching between the shower and the shower, it reduces various movements during bathing, brings about many effects that could not be obtained conventionally, and makes life more enjoyable and enriching. It is something that can be done.
