The present invention relates to a micro-bubble generating device, and more particularly, to generate ultra-fine bubbles by inhaling outside air in the form of pulse waves from the solenoid valve by mixing with the bath water by the negative pressure of the vacuum chamber opened and closed by the solenoid valve. The present invention relates to a microbubble generating device for bath water.

A foam bath used to generate bubbles in the bath water generally generates a small bubble with a motor in the lower part of the bath, and is a bath method to obtain the same effect as a massage by the bubble. Ultrasonic waves generated when bubbles are generated Compresses and relaxes the skin, giving it a warming effect. In particular, when the diameter of the bubble is less than 1mm is called an ultrasonic bath, which is known to have a therapeutic effect, such as muscle pain, skin care, traumatic sequelae. In addition, since bubbles that are broken at the surface of the water adhere to the positive ions in the air, negative air ions increase in the vicinity of the surface of the water. At this time, negative air ions are known to have a calming effect to stabilize the mind and relieve stress.

The bubble generator used in such a foam bath has been proposed in the domestic patent application No. 1989-0020628 as "circulation pump control bubble generating bath by the inverter". As shown in FIG. 1, the bubble generating bath includes a tub body (A), a circulation pump (P), a hot water circulation passage (D), a jet nozzle (2, 3), an intake port (5), an inverter (E), It consists of an insulation device.

Here, the tub body (A) is a tub container containing the bath water, the circulation pump (P) is mounted to the outside of the tub body (A) is driven by a power-operated motor (M). In addition, the hot water circulation passage (D) is disposed between the tub body (A) and the circulation pump (P) and the hot water forced supply passage and hot water suction passage having at least one end opening to the tub body (A). Consists of In addition, at least one jet nozzle (2, 3) is attached to the end of the hot water forcing supply passage, the intake port (5) from the jet nozzle (2, 3) to the tub body (A) It is connected to the hot water forcing supply passage so as to eject bubble-generated hot water. In addition, the inverter (E) is disposed between the power operating motor (M) and the power of the circulation pump (P) to change the rotational speed of the motor (M) easily and smoothly by the frequency modulation to operate the circulation pump. By controlling it, the amount of ejected water and the ejection pressure of the ejected hot water are adjusted in various modes. Finally, the insulating device serves to prevent the current generated by the inverter (E) from being transferred to the hot water of the bath body (A).

However, since the bubble generating device of the conventional bubble generating bath as described above ejects the bubble generating hot water by the ejection nozzles (2, 3), it is possible to obtain only the massage effect by bubbles as in the general bubble generating device, and other special effects. It is hard to expect.

In addition, as shown in FIG. 1, since the size of the entire apparatus is large and the structure is complicated, management such as construction and maintenance has been difficult.

The present invention has been proposed to solve the problems of the conventional bubble generator as described above, the suction pump and the drive motor for operating the pump, and parts such as pressure tank to temporarily receive the bath water generated microbubbles The whole body can be downsized and simplified to facilitate the construction, handling, and management of the entire device.The air inlet and the open air are opened and closed by a solenoid valve, allowing the outside air to be mixed with the bath water in the form of a pulse wave. The purpose is to diversify the functionality of the bath water by generating ultra-foam bubbles.

Therefore, in order to achieve the above object, the present invention provides a pump mounted between a water supply source and a pressure tank of a water supply pipe to supply water of a water supply source to a pressure tank, and between a water supply valve and a pump of a water supply pipe to supply external air to the water supply pipe. A connected air supply pipe, a pressure tank mounted between the pump and the tub of the water supply pipe to temporarily store the mixed water of the outside air, and an injection nozzle mounted at the end of the water supply pipe to inject the mixed air discharged from the pressure tank into the bathtub. In the bubble generator configured of the above, the air supply pipe is provided with a bubble generator is equipped with a vacuum chamber which is opened and closed by the solenoid valve and sucks the outside air in the form of a pulse wave by the negative pressure generated by the pump.

Hereinafter, an embodiment of a microbubble generating device according to the present invention will be described in detail with reference to the accompanying drawings.

Here, first, the pump 3 is a general pump such as a centrifugal pump operated by the drive motor 27, and the absorption port 45 and the absorption port immersed in the water W of one side of the bathtub 10 serving as a water supply source. (45) On the opposite side is mounted on the water pipe (11) connecting the spray nozzle (9), which is immersed in the bathtub (10) on the conduit to mix the bubbles in the water (W) sucked from the bathtub (10) to form a tub again It serves as a prime mover to supply to (10). To this end, the pump 3 is mounted on the water supply pipe 11 between the air supply pipe 5 to which the outside air is supplied and the pressure tank 7 to temporarily store the outdoor mixed water.

In addition, the air supply pipe 5 has a pump 3 having one end connected between the water supply valve 13 of the water supply pipe 11 and the pump 3 so as to supply external air to the water supply pipe 11 by the pumping force of the pump 3. It is connected adjacent to, and the other end is open to the outside air.

The solenoid valve which can be used is adopted, and by opening and closing the vacuum chamber 17 at a high speed, the outside air is sucked in the form of a pulse wave in the body 19 under negative pressure by the suction force of the pump 3.

Thus, the pressure tank 7 mounted downstream of the pump 3 of the water supply pipe 11 so as to temporarily store the water supply mixed with the outside air from the air supply pipe 5 receives the outdoor air mixed water pumped by the pump 3. A container having a size larger than an appropriate volume to be accommodated, a bleeder 29 is mounted on the upper end to maintain the internal pressure below a predetermined value, and the pressure sensor 49 for measuring the internal pressure is also a bleeder ( 29) It is mounted on one side. At this time, the bleeder 29 is a kind of relief valve which is opened only when the pressure in the pressure tank 7 is higher than a predetermined value, as can be seen from FIG. 2. In addition, the pressure sensor 49 transmits the measured pressure value to the electronic controller 30 to maintain the internal pressure of the pressure tank 7 at an appropriate value under the control of the electronic controller 30.

In addition, the injection nozzle 9 mounted at the end of the water supply pipe 11 sprays the outdoor mixed water extruded from the pressure tank 7 through the water supply pipe 11 to the bath water for foaming, such as the bathtub 10. It plays a role.

The mesh filter 33, the nozzle plate 35, the filtration filter 37, the filtration cap 39, and the intermediate cap 40 can be stacked and mounted in this order. Therefore, the inner cap 31-2 is detachably attached to the inner cap 31-2, the intermediate cap 40 to which the mesh filter 33, the nozzle plate 35, the filtration filter 37, and the filtration cap 39 are sequentially inserted and fixed. It is screwed together, and the inner end of the middle cap 40 is closed by the valve cover 42. At this time, the intermediate cap 40 has a plurality of through-holes 44 are formed at equal intervals on the top of the side wall to spray the outside air mixed water discharged from the filtration cap 39 to the outside through the outer cap (31-1). .

In addition, the mesh filter 33 fitted to the innermost side of the outer case 31 is in contact with the valve cover 42 in a state of being fitted to the intermediate cap 40, and the outer case 31 through the water supply pipe 11. The outdoor mixed water entering the furnace is crushed by a small mesh. The nozzle plate 35 stacked directly above the mesh filter 33 is a button-shaped disc, which is gently curved so that its center portion is convex outward, and at least two nozzle holes 41 are formed on the same radius of the body. It is penetrated with equal angular spacing. In addition, the filtration filter 37 mounted on the nozzle plate 35, that is, outside the nozzle plate 35, similarly to the filter 33 passes through the nozzle hole 41 of the nozzle plate 35 and is blown out. It serves to crush the water again through internal micropores. In addition, the filtration cap 39 in close contact with the outside of the filtration filter 37 has at least two or more openings 43 penetrated through the top of the hemispherical cylinder.

In addition, the electronic control unit 30, which is electrically connected to the water supply valve 13, the solenoid valve 15, the drive motor 27, the pressure sensor 49, and the temperature sensor 50, is provided in the apparatus 1. Mounted on a circuit board to control the operation and stop of the drive motor 27, and open and close the water supply valve 13 and the solenoid valve 15 at a set time interval, while the pressure sensor 49 and the temperature sensor 50 The operation of the drive motor 27 and the opening and closing of the valves 13 and 15 are controlled according to the internal pressure and temperature of the pressure tank 7 and the line pressure of the water supply pipe 11 sensed by the pressure tank 7.

Finally, the pressure sensor 49 mounted on the upper end of the pressure tank 7 so as to sense the internal pressure of the pressure tank 7 is largely upper and lower cases 61 and 62, the elastic membrane 63 as shown in FIG. ), A pressure pin 65, a hydraulic pin 67, and an on-off switch 69.

Here, the upper and lower cases 61 and 62 form an outer body of the pressure sensor 49, and are coupled to be opened and closed at an intermediate portion. In the upper case 61, the electrode terminal 85 connected to the on / off switch 69 on the upper surface protrudes at intervals of 120 degrees, and a spring hole 81 protrudes from the center. The lower case 62 has a through hole 73 open toward the pressure tank 7 at the center of the bottom thereof.

In addition, the elastic membrane 63 fitted inside the through-hole 73 of the lower case 62 is forcibly fitted to the inner wall surface of the lower case 62 to maintain the airtightness of the through-hole 73 with a cylindrical rubber membrane. Corrugated band 87 is formed on the upper surface to expand and contract up and down according to the pressure P of the pressure tank 7 acting through the 73, and a projection for fitting the pressing pin 65 to the upper center portion ( 89) protrudes.

The pressing pin 65 inserted into the projection 89 on the upper surface of the elastic membrane 63 is a hollow rod having a pointed end, and is provided by the lower case 62 through a fixing plate 91 coupled to the lower case 62 by a screw 93. Bar) to secure a space capable of moving up and down by the depth of the recess formed in the center of the bottom of the fixing plate (91).

When the pressing force by the pressing pin 65 is released, the upper side is brought into contact with the distal end and lowered to the original position by the reaction force of the rebound spring 79. In addition, the hydraulic pin 67 adjusts the reaction force against the pressure pin 65 by elevating the adjustment screw 83 screwed to the upper end of the spring hole 81 of the upper case 61 to press the rebound spring (79). It is supposed to be.

Finally, the switch 69, which is turned on and off according to the upward and downward movement of the pressing pin 65, is attached to the bottom of the upper case 61 and is pressurized together when the hydraulic pin 67 is pressed to bend upward. The fixed piece 76 attached to the piece 75 and the movable piece 75 of the upper case 61 so that the contact 77 with the movable piece 75 falls when the movable piece 75 is bent. ) At this time, the movable piece 75 and the fixed piece 76 are electrically connected to the electrode terminal 85, respectively.

Referring to the operation of the micro-bubble generating device 1 according to the present invention configured as described above are as follows.

When the device 1 is operated, the electronic control unit 30 first operates the motor 27 to drive the pump 3 and simultaneously opens the water supply valve 13. Accordingly, the bath water W contained in the bathtub 10 is introduced into the water supply pipe 11 through the absorption port 45 by the pumping force of the pump 3. The bath water (W) introduced into the water supply pipe (11) passes through the open / close valve (13) and passes through the air supply pipe (5), and is mixed with the outside air introduced from the air supply pipe (5).

To this end, the electronic control unit 30 opens the solenoid valve 15 to allow the outside air to be sucked into the vacuum chamber 17, and the solenoid valve 15 is opened and closed at high speed by the pump 3. External air is intermittently introduced into the cylindrical body 19 of the vacuum chamber 17 in a vacuum negative pressure state.

At this time, when the pumping force of the pump 3 is increased or the pumping interval is shortened so that excessive negative pressure is applied to the inside of the cylindrical body 19, the suction force acting on the vacuum valve 23 is increased by this negative pressure. Accordingly, the vacuum valve 23 overcomes the repulsive force of the compression spring 47 and moves into the body 19 to open the through hole 25, and the vacuum chamber 17 not only the body 19 but also the vacuum bag. (21) The interior is also in a vacuum state.

On the contrary, when the operation of the pump 3 stops momentarily, or the pumping interval or the pumping force drops, a large amount of outside air is stored inside the body 19 of the vacuum chamber 17 by the continuous opening of the solenoid valve 15. The vacuum negative pressure inside the relatively small body 19 that is introduced may be lost, but the outside air introduced into the vacuum chamber 17 is also introduced into the vacuum bag 21 through the through hole 25, so that the vacuum The chamber 17 may have a margin for maintaining the inside of the vacuum state. Therefore, even if the pumping force of the pump 3 is temporarily lost, the vacuum chamber 17 can be maintained in a vacuum state for a considerable time, so that intermittent inflow of outside air due to the opening of the solenoid valve 15 can be continued. Will be.

In this way, the bath water mixed with the outside air is temporarily stored in the pressure tank 7 after passing through the pump 3, where the bath water and the outside air are sufficiently mixed, and then the pumping force of the pump 3 It is delivered to the spray nozzle 9 along 11). At this time, the overpressure generated in the pressure tank 7 is removed to the outside through the bleeder (29).

Nevertheless, when the inside of the pressure tank 7 is maintained in an overpressure state, the pressure P inside the pressure tank 7 is applied from the through hole 73 in the lower case 62 of the pressure sensor 49. As a result, the elastic membrane 63 expands to raise the pressing pin 65 fitted to the protrusion 89. The pressure pin 65 thus raised pushes up the hydraulic pin 67 and simultaneously pushes the movable piece 75 of the switch 69 to short the contact 77. The switch 69 signal generated at this time is a pressure tank. The controller 30 is notified to the controller 30 that an overpressure has occurred, and the controller 30 immediately controls the internal pressure of the entire apparatus 1.

Meanwhile, the outdoor mixed water reaching the injection nozzle 9 is crushed finely while passing through the mesh filter 33 firstly, and then collides with the nozzle plate 35 through the nozzle hole 41 as shown in FIG. 4. It collides with the filter 37 at high speed. The outside air mixed water crushed into ultrafine particles again by the collision with the filter 37 is injected into the intermediate cap 40 through the plurality of open holes 43 of the filtration cap 39, and again, the through hole 44 and the outside. It is sprayed to the bathtub 10 via the cap 31-1, and foams are formed of bubbles of ultra-fine particles in the bath water W contained in the bathtub 10. In this case, the filters 33 and 37 may use a material containing minerals, and thus antibacterial, deodorizing function and anion, and far infrared radiation function may be expected from the bubble foam injected.

According to the micro-bubble generating device according to the present invention as described above, it is possible to ultra-miniaturize the bubbles of the mixed air to be injected into the bathtub by intermittently inhaling the outdoor air mixed in the bath water as a pulse wave by the solenoid valve which opens and closes at high speed. . Therefore, it is possible to change the bath water to be alkaline by the ultra-mini strength cloth, and to softly change the bath water like milk by generating ultrasonic waves and anions.

In addition, the ultra-fine micropore's pore penetration and buoyancy draw out fat and impurities accumulated deep in the pores of the bather's pores and supply oxygen energy deep into the skin to clean the skin, exfoliate skin, moisturize and whiten skin, and enhance skin elasticity. The beauty of the skin can be obtained, and the effects of atopic dermatitis, acne, athlete's foot, eczema and other skin diseases, as well as fatigue recovery, hangover removal, body temperature rise, blood circulation improvement, insomnia can be obtained.

In addition, it is possible to expect the effect of promoting the metabolism of the bath by generating negative ions in a natural manner by ultra-miniature guns away from the artificial method using the electrical friction.

In addition, it is possible to miniaturize and simplify the entire device, such as the structure and components that generate microbubbles, thereby facilitating the handling and management, such as installation, movement, and use of the device.
