In the process of passing through the bubble generator 6, the air supply pipe 8
Air that is sucked or pressurized from is made into fine bubbles and jetted into the bathtub 2 together with warm water.

Regarding the mechanism of formation of fine air bubbles in the bubble generator 6, when hot water and air fluids are introduced under pressure from the inlet 23 of the bubble generator 6 into the internal space of the casing 21, the fluids are generated. Flow reaches the inside from the flow hole 30 of the upstream air bubble dispersing element 26 as shown by the arrow in FIG. 4, and the circular path is blocked by the small-diameter disk 29 to change the direction, and the small chambers communicating with each other. After 27, 27a ..., Radial right angle collision, dispersion, merging, meandering, eddy current, etc. are combined in a radial direction from the central portion to the outside, resulting in a complicated flow.

In this way, the upstream air bubble dispersion element 26
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 dispersion 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 disc 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 again enters the bubble dispersion element 26 on the downstream side from the flow hole 30.
Then, through the small chambers 27, 27a, ... Again, from the central part toward the outside at right angles, complicatedly flow sequentially inside the bubble dispersion element 26 due to 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 ...

In the casing 21, the air bubble dispersion and collection elements 38, each of which is composed of a small-diameter circular plate 29 having 30 chambers, are provided in the casing 21.
Four types of internal units, 4 units, 6 units and 10 units are used, and the air supply pressure is 1 to 5 Kg / cm.
² , the hot water and air were supplied under pressure at a water flow rate of 3 to 25 liters / minute and an air flow rate of 1 to 9 liters / minute, and passed through the internal space only once, and the bubble diameter at the outlet 24 was measured. , 45μ
It was confirmed that fine bubbles were formed to about m to 66 μm, and it was confirmed that the gas-liquid interfacial area was remarkably increased even by only one passage. Therefore, naturally, the bubble diameter in the bathtub 2 is It is further miniaturized by repeating the liquid mixing.

Further, regarding the total number of dispersions of the bubble dispersion element 26, the size of the large and small particles arranged radially in sequence from the center is used.
This is determined by the number of small chambers 27, 27a ... Of the discs 28, 29. For example, in the case of the hexagonal shape in plan view shown in FIG. 7, the number of chambers is 6, 12, 18 ( 3 of 36 rooms)
The total number of dispersion in the case of one fluid in which the row-shaped disc 28 and the bubble-dispersing element 26 obtained by superimposing the three-row-shaped disc 29 having three, nine, and fifteen chambers (total of 27 chambers) are combined. Reaches thousands of times, and naturally becomes a product of the multipliers for two fluids (hot water and air) or more.

It should be noted that the above-mentioned total number of dispersions is the disk 28 and the disk 29.
, The number of the fluids to be generated while passing through the bubble dispersion element 26 by the small chambers 27, 27a ... Which communicate with each other. It is the product of the total number of variances, and by increasing or decreasing the number of columns in the small chambers 27, 27a ...
It is possible to increase / decrease appropriately, and also in the bubble generator 6 using the bubble dispersing and collecting element 38, as in the above, right-angle collision, dispersion,
The merging, meandering, swirling, etc. are repeated and ejected.

When the seat surface 40 is formed into a tapered surface, as shown in FIG. 25, the tapered surface serves as a guide surface when the seal member 55 is mounted, so that the seal member 55 can be prevented from being caught.

Also, with respect to the fluid which is about to leak between the end faces of the columnar projections 50 of the lids 25 and 25a and the back surface of the large diameter disc 28 of the bubble dispersion and assembly element 38, the seal seating surface of the columnar projections 50 is also prevented. Since the seal member 55 is mounted in the seal groove 54 defined by the seal seat surface 40 of the circular plate 40 and the disc 28, leakage from the outer periphery of the columnar protrusion 50 can be prevented, and the outer periphery of the columnar protrusion 50 can be prevented. The gaskets that are generally installed in the are not required.

Next, in the case where the seaweed tank 9 is provided in the circulation conduit 5, the seaweed comes into contact with the hot water flowing in the seaweed tank 9, which is generally known from the seaweed. Acidic polysaccharides such as alginic acid and fucodine, various minerals, UV absorbing substances and other functional substances, which are substances that effectively function to regulate various ecological systems directly related to human health, are eluted and When air and warm water pass through the bubble generator 6 and are jetted out into the bathtub 2, the functional substance, which is an eluting component, becomes high at the interface of the bubbles finely divided by the bubble generator 6 having the dispersive mixing action described above. Adsorbed to concentration.

Are arranged, and two small diameter discs 29 are arranged so that the small chambers 27, 27a ... are arranged in different positions so that the small chambers 27, 27a ... communicate with the other small chambers 27, 27a ... which are opposed to each other. Since the bubble collecting and collecting element 38 is formed as a unit because the bubble collecting and collecting element 38 is unitized, the assembly of the bubble generator 6 can be performed very easily, and the bubble collecting and collecting element 38 is arranged in the casing 21 to form a bubble. Since the dimension L2 between both ends of the dispersion collecting element 38 is set larger than the dimension L1 between both ends of the casing 21, the lids 25 and 25a can be attached to both ends of the casing 21 to sandwich and fix the bubble dispersion collecting element 38. In addition to the effect of forming fine air bubbles in the same manner as in the above, since the close contact state of the upper end surfaces forming the small chambers 27, 27a in the disks 28, 29 can be firmly maintained, each of the disks 28, 29 can be maintained.
Since the backlash can be prevented, it is possible to prevent problems such as short-circuited flow caused by leakage from the upper end surface of the small chambers 27, 27a ... Or the outer peripheral side of the large-diameter disk 28, and defective dispersion of bubbles due to pulsating flow. .

Further, inlets are provided at both ends of the cylindrical casing 21.
A lid 25, 25a having a 23 and an outlet 24 is detachable, a columnar projection 50 is provided to be inserted into the casing 21, and a half groove groove is formed on the peripheral side of the tip of the columnar projection 50. The seat surface 40 is formed, and the outer diameter of the large-diameter disk 28 is casing.
It is formed in a size that does not closely contact the inner peripheral surface of 21 and
Seal seat surfaces 40 in the form of half-grooves are formed on the peripheral side of the back surface where 27, 27a ... Are not formed, and the small chambers 27, 27a of each other are formed.
The two large and small discs 28 and 29 are connected to each other to form a bubble dispersing element 26 so that the positions of the plurality of small chambers 27 and 27a facing each other are different from each other. 26 are arranged in the casing 21 so that the disks 28 and 29 having the same diameter are adjacent to each other, and the adjacent seal seat surfaces 40
Since the seal member 55 is provided in the seal groove 54 defined by the seal groove 55, the seal member 55 and the air bubble dispersion element 26 are simply inserted and arranged in the casing 21 in order.
Since the seal member 55 can be installed in the seal groove 54 at the same time as defining 54, the assembling of the bubble generator 6 is extremely simple, and the seal member 55 is surely installed in the seal groove 54. By restricting the short-term flow of the fluid from the outer peripheral side of the circular disk 28, it is possible to prevent problems such as poor dispersion of bubbles in the same manner as described above, and also to prevent the cylindrical seat 50 from sticking to the seal seat surface 40 and the circle. Since the seal member 55 is mounted in the seal groove 54 defined by the seal seat surface 40 of the plate 28, the columnar protrusion
50 Leakage from the outer periphery to the outside can be prevented at the same time, and the cylindrical protrusion
50 Gaskets that are generally provided on the outer circumference are not required,
Moreover, since the outer diameter of the large-diameter disk 28 does not come into close contact with the inner peripheral surface of the casing 21, it is not necessary to make the processing accuracy of the inner peripheral surface of the casing 21 in which the plurality of bubble dispersion elements 26 are arranged precise. Machining of 21 itself will 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, the seaweed is accommodated and the communication holes 11, 11a are provided.
A seaweed tank 9 with a seaweed container 12 in which is formed
Since it was interposed in the circulation conduit 5, fucoidan eluted from the seaweed in the seaweed accommodating section 12, slime containing acidic polysaccharides such as alginic acid, various mineral components, etc. Due to the adsorption of the functional substance, the bubbles contact the skin of the body as described above, and the functional substance is efficiently absorbed from the skin, and further, the bubbles are miniaturized. Since the functional substance is adsorbed at a high concentration, the absorption efficiency from the skin is remarkably improved, which is useful for improving the beauty effect and health maintenance / promotion effect. Is.
