Next, the operation of the hot water spouting device in the bathroom according to the present invention will be described. When hot water is pressurized and sent from the feed pipe 2a to the bubble generator 5 by the hot water supply facility 2, external air is passed through the edge ejector section 9. The air sucked from the introduction pipe 10 or pressurized and supplied by the blower is made into fine bubbles during the process of passing through the bubble generator 5 and is supplied to the jet nozzle 3 together with the hot water, and jetted from the sprinkling holes 6 of the jet nozzle 3. In a state where fine air bubbles are suspended (turbid) in each linear flow of the shower or in the rod-shaped flow ejected from the single-jet outlet 6a, the air is ejected to the body to remove dirt on the skin.

As the cleaning mechanism, the impact force when each linear flow or rod-shaped flow of the shower hits the skin surface, the interfacial flow generated simultaneously on the surface, and the impact force when the air bubbles hit the skin surface and burst. Efficiently removes dirt adhering to the surface of the skin by the detergency resulting from the synergistic action with, and at least 45 μm as described later.
Since the bubbles are miniaturized up to about 66 μm, the adsorption power of the bubble surface is remarkably increased, and the dirt adhering to the skin surface is efficiently adsorbed and removed on the bubble surface. Since the size (pore diameter) of the hair follicles that connect with the gland and the sebaceous gland is about 80 μm to 150 μm, the bubbles hit by the jet enter the sweat pores and the hair follicles.
The dirt adhering to the pores and the pores of the sweat is scraped off and adsorbed on the surface of the bubbles and removed at the same time.

Further, since the dirt of the skin is mixed with cosmetics and sebum, it is often hydrophobic and the bubbles are also hydrophobic, so that the dirt is well adsorbed on the surface of the bubbles. For example, the air bubbles act as a carrier that desorbs dirt from the skin surface and carries it away.

Next, when hot water in which bubbles are suspended flows and is ejected in the magnetic field generated by the magnet device 11, metabolic physiological functions are promoted by the biological permeation action in addition to the above-mentioned washing action. Therefore, when the wave energy is increased by passing the hot water through the magnetic field, energy in the far infrared region is released and
High-frequency electromagnetic energy of GHz or higher is generated, penetrates into the living body through the skin, is absorbed and activated at the cell level of the living body, and the high-frequency electromagnetic energy contributes to the removal of dirt adhering to the skin. .

Next, regarding the mechanism of forming fine air bubbles in the bubble generator 5, when hot and air fluids are made to flow under pressure from the inlet 23 of the bubble generator 5 into the internal space of the casing 21, The flow of this fluid reaches the inside from the flow hole 30 of the bubble generating element 26 on the upstream side, as shown by the arrow in FIG. 3, for example, and the circular path is obstructed by the small-diameter disk 29 to change the direction and communicate with each other. Through the small chambers 27, 27a, ..., From the central part to the outer side, the state of radial right-angle collision, dispersion, merging, meandering, vortex flow, etc. is combined to flow complicatedly.

Thus, the bubble generating element 26 on the upstream side
The fluid that has passed through and has reached the inner peripheral surface of the casing 21 is a small chamber 27 of the bubble generating element 26 on the downstream side from the flow passage 31 formed by the inner peripheral surface of the casing 21 and the small-diameter disk 29, 27a ... Enters in the central portion by a complicated flow such as right-angle collision, dispersion, merging, meandering, and vortex as described above, and then enters the bubble generating element 26 on the downstream side from the flow hole 30 again.
Then, while again passing through the small chambers 27, 27a, ..., from the central portion toward the outside, the fluid flows in the inside of the bubble generating element 26 in a complicated manner due to a right-angle collision, dispersion, merging, meandering, vortex flow, etc. Are made into fine bubbles, and the bubbles are suspended (whitened) and ejected from the outlet 24.

As described above, the fluid is the small chambers 27, 27a.
At right angles to the bottom and side walls 32 of…, each chamber 27, 27a…
To other multiple chambers 27, 27a ..., multiple chambers 2
7, 27a ... to another small chamber 27, 27a ..., meandering, and more than one small chamber 27, 27a ... to each small chamber 27, 27a ...

Further, since the bubble diameter of the fine bubbles is made smaller than the size of the pores and the pores of the skin, the adsorbing power of the bubble surface is remarkably enhanced, and the dirt adhering to the skin surface is efficiently adsorbed on the bubble surface. In addition to being removed, the air bubbles hit by the spray enter the sweat pores of the eccrine glands and the hair lips that are connected to the apocrine glands and the sebaceous glands, and the dirt adhering to the sweat pores and hair is scraped off and adsorbed to the surface of the air bubbles at the same time. it can.

Since the bubble diameter can be remarkably miniaturized by the complicated flow due to the combination of the above, and the large total number of dispersion, the bubble surface area, that is, the adsorption surface area can be significantly increased. Since it is not discharged in a short circuit, the size of the fine bubbles can be made uniform, which ensures that only the fine bubbles are suspended in each linear flow or rod-like flow of the shower. The cleaning action is good, and the flow direction of diffusion and aggregation in the bubble generating element 26 is the radial direction, and since it is complicatedly bent, the flow path length can be lengthened, so that the bubble generator 5 can be downsized.

The size is such that the flow passage 31 is formed in the inside, and the large-diameter discs 28 are arranged on both sides in the annular sealing body 37, and two small-diameter discs 29 are arranged between them to form bubbles. Since the bubble generating and collecting element 38 is formed as a unit, the bubble generating and collecting element 38 is unitized, so that the bubble generator 5 can be assembled very easily, and the desired number of the bubble generating and collecting elements 38 can be arranged in the casing 21. However, since the collar pieces 36, 36a of the annular sealing body 37 in the bubble generating and collecting element 38 are sandwiched by the lid bodies 25, 25a at both ends of the casing 21 so as to elastically deform, fine air bubbles similar to the above. In addition to the effect of conversion, small chambers on disks 28 and 29
The tight contact of the upper end surface that forms 27, 27a, etc. can be maintained firmly, and rattling of the disks 28, 29 can be prevented, so that the small chamber 2

Since the packing body 60, which should be pressed when the lids 25 and 25a are attached, is provided on the entire outer surface of the flange pieces 36 and 36a, due to the dimensional error of the inner peripheral diameters of the flange pieces 36 and 36a that are in close contact with each other, Even if the inner peripheral edge of 36a is not pressed, the flange piece 3
Make sure that the entire outer surface of 6, 36a is elastically deformed, and the large diameter disc 2
8 Since the sealing function on the outer peripheral side of the back surface is improved, problems such as the above-mentioned short-circuit flow and defective dispersion of bubbles can be prevented, and the size of fine bubbles can be maintained uniform, which makes By ensuring that only the fine bubbles are suspended in each linear flow or rod-like flow, the cleaning action by the above-mentioned bubbles is good.

Further, the ring-shaped seal member 37 in the bubble generating and collecting element 38 in which a desired number is arranged in the casing 21.
In the space inside the collar pieces 36, 36a and on the outer surface side of the collar pieces 36, 36a of the ring-shaped seal body 37, a packing body 60 with a communication hole 65 formed in the center is provided, and when the lid bodies 25, 25a are mounted. Packing body
Since 60 and the collar pieces 36, 36a are elastically deformed, in addition to the above effect, the collar pieces 36, 36a of the ring-shaped seal body 37 are sealed from around the circulation hole 30 on the back surface of the large-diameter disk 28. A sealing function can be provided between the points, and other factors such as the above-mentioned short-circuited flow and defective dispersion of bubbles can be removed, and the cleaning action by the bubbles can be reliably maintained. .

Since the seal member 55 is provided in the seal groove 54 defined by 40, the seal groove 54 can be defined by simply inserting the seal member 55 and the bubble generating element 26 into the casing 21 one by one. At the same time, the seal member 55 is placed in the seal groove 54.
Since the air bubble generator 5 can be mounted very easily, the seal member 55 is surely mounted in the seal groove 54, so that the fluid from the outer peripheral side of the large-diameter disk 28 is short-termed. As described above, it is possible to prevent defects such as poor dispersion of air bubbles by regulating such a flow, and the seal groove 54 defined by the seal seat surface 40 of the columnar protrusion 50 and the seal seat surface 40 of the disc 28. Since the seal member 55 is mounted inside, leakage from the outer circumference of the columnar protrusion 50 can be prevented at the same time, and gaskets generally provided on the outer peripheral side of the columnar protrusion 50 are unnecessary, and a large diameter Since the outer diameter of the disc 28 does not come into close contact with the inner peripheral surface of the casing 21, it is not necessary to make the machining accuracy of the inner peripheral surface of the casing 21 in which a plurality of bubble generating elements 26 are arranged, so that the casing 21 itself is machined. Will also be easy.

Further, since the seal seat surface 40, which is the bottom of the seal groove 54, is formed into a tapered surface, the tapered surface serves as a guide surface when the seal member 55 is mounted, so that it is difficult to visually confirm the casing. It is possible to prevent a sealing failure due to the sealing member 55 being caught in the inside 21.

Further, since the magnet device 11 for magnetizing water is provided, the metabolic physiological function can be promoted by the biological permeation action in addition to the above-mentioned cleaning action, and by the combined action with the generated high frequency electromagnetic energy. Further, the dirt on the skin can be removed efficiently, and the practical effect is great.
