Description

  The present invention relates to an ozone water shower apparatus that uses only tap water pressure.

  Conventionally, ozone water has been widely used for food sterilization, medical sterilization, etc. If ozone water in which ozone gas is dissolved is used in a hot water shower for washing hair, in addition to disinfection and sterilization effects, It has been known that it has a cleaning effect of decomposing cosmetic agents and the like and an effect of improving blood flow in the vicinity of the hair root. It was also recognized as effective in disinfecting and removing odors from the hands and wrists of hairdressers after performing hair care.

  As a device for generating such ozone water, a high pressure is applied to a mixed gas of ozone gas and air generated from an ozone generator to introduce water into a water tank as a microbubble and pressure is applied to a water supply pipe. It was a method of blowing.

  Since the pressure of the water supply that is generally supplied is about 150 to 200 kpa (1.5 to 2.0 kg per square centimeter), it is necessary to apply a considerable pressure to blow in the mixed gas of ozone gas and air. Since a pressurizing pump for pressurizing the gas is provided, the apparatus becomes large and the control becomes complicated.

  On the other hand, an ozone water generator using a gas-liquid mixer such as an aspirator and utilizing only the tap water pressure has been proposed. For example, it was as described in Patent Document 1.

  FIG. 6 shows a configuration of a conventional ozone-containing liquid generating apparatus described in Patent Document 1.

  In FIG. 6, an ozone-containing liquid generator 60 includes an ozone generator 61 that generates ozone, a gas-liquid mixer 62 that generates ozone water by containing the generated ozone in water, and a raw material for the ozone generator 61. Separated from the ozone water 65, the gas introduction path 63 for introducing gas, the liquid introduction path 64 for introducing water into the gas-liquid mixer 62, the gas-liquid separator 66 for gas-liquid separation of the generated ozone water 65, and the ozone water 65. A reflux gas reflux path 67 for refluxing a gas containing ozone to the gas introduction path 63, an ozone-containing liquid outlet path 68 for leading the ozone water 65 after gas-liquid separation to the outside, and a liquid inlet path 64 are provided. And a constant flow valve 69 that regulates the upper limit of the flow rate of the water introduced into the gas-liquid mixer 62.

JP 2013-202493 A

  However, in the conventional ozone-containing liquid generating apparatus, it is necessary to reduce the ozone gas concentration exhausted together with the ozone water from the discharge port 70 to a safe level. It was necessary to return to 61 or limit the flow rate of water to the gas-liquid mixer 62.

  The present invention has been made in order to solve the above-described conventional problems, and an object of the present invention is to provide a small ozone water shower device that generates ozone water having a high ozone gas concentration only with tap water pressure with a simple configuration. It is to be.

  The ozone water shower apparatus according to the present invention that solves the above-described conventional problems is an ozone generator that mixes and dissolves an ozone generator that generates ozone gas from the air, and ozone gas generated by the ozone generator and water that flows from the water supply. An aspirator that generates water, and a sealed pressurized diffusion mixer in which ozone water released from the aspirator is temporarily stored, pressurized and stirred, so that bubbles of ozone gas are further dissolved in ozone water; And a shower head for discharging ozone water having an increased ozone concentration from the pressure diffusion mixer.

  Thereby, the ozone water shower apparatus can produce | generate ozone water with high ozone gas concentration only by the pressure of tap water, and it becomes possible to reduce the whole apparatus in size.

  In addition, since the aspirator is equipped with a vortex generator that rotates the water that flows in, the ozone water shower device vigorously stirs the ozone water in the pressurized diffusion mixer and dissolves the ozone gas in the bubble into the ozone water. It becomes easy to do.

  In addition, the ozone water shower device has an ozone concentration of 20 ppm to 60 ppm from the ozone generator, and the capacity of the pressure diffusion mixer is approximately three times the amount of ozone water inflow per second. Since ozone is dissolved in ozone water mixed with this concentration of ozone, it is stored in a pressure diffusion mixer, so ozone water with the required ozone concentration is discharged from the shower head, and from the shower head. Low concentration ozone gas is released.

  In addition, the amount of ozone water flowing out from the pressurized diffusion mixer of the ozone water shower unit to the shower head side per unit time is the same or slightly larger than the amount of ozone water flowing out from the aspirator side per unit time. The pressure diffusion mixer is not filled with ozone water, and the self-priming action of the aspirator will always work.

  Furthermore, the shower head of the ozone water shower device is provided with a switch for controlling the activation of the ozone generator. When the switch is on, ozone gas is mixed by an aspirator, and when the switch is off, air is mixed.

  For this reason, since the water discharged from the shower head can be switched between ozone water and water having a high air concentration at hand, the operator can easily switch between suitable water according to the degree of contamination of the object to be cleaned. It becomes possible.

  The ozone water shower apparatus of the present invention has the advantage that ozone water having a high ozone concentration can be generated only by the pressure of tap water, and the entire apparatus can be made compact.

  Embodiments of the present invention will be described below with reference to the drawings. In the embodiment described below, an ozone water shower apparatus that can be installed on a washstand in a beauty salon or a hair salon by downsizing the entire apparatus will be described as an example.

(Embodiment 1)
FIG. 1 is a diagram showing a configuration of an ozone water shower apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a diagram showing a structure of an aspirator (Nishizawa metal aspirator product name MA-2) used in the present embodiment. It is.

  First, the structure of the ozone water shower apparatus in this Embodiment is demonstrated using FIG. 1 and FIG.

  In FIG. 1, a manual open / close valve 2 is an open / close valve that supplies hot water heated from the water supply 1 while maintaining its water pressure as it is to a water supply port of an ozone water shower device. The ozone water shower device includes a water flow / water pressure detection switch 3, an aspirator 4, an ozone generator 8, a pressure diffusion mixer 10, and a shower head 11, and a flow path and pressure in the aspirator 4. The water supply port of the diffusion mixer 10 is connected in a straight line in the horizontal direction via the flowing water channel 5.

  The water flow / water pressure detection switch 3 is a switch for detecting the water flow or water pressure of the hot water from the manual opening / closing valve 2, and includes a water flow switch comprising a reed switch that is turned on / off by movement of a magnet attached to a rotating plate in the flow path. This is a water pressure detection switch in which the diaphragm pushes the micro switch by the water pressure in the flow path.

  The ozone generator 8 generates ozone gas by applying an alternating high voltage between metal electrodes sandwiching an insulator to cause silent discharge, and passing external air 6 between the electrodes. For this reason, dust in the air causes troubles in the generation of ozone gas, so the air intake portion of the ozone gas generator 8 is provided with an air filter 7. Further, since the ozone gas generator 8 has a high voltage circuit and it is not preferable to enter moisture, a check valve 9 is provided.

  The ozone generator 8 is driven by a DC power source (AC adapter), but operates only when both the power switch 12 and the water flow / water pressure detection switch 3 are turned on.

  The aspirator 4 is a small metal aspirator that mixes the liquid flowing in from the water supply port 21 and the gas flowing in from the air intake port 23 and discharges the gas-liquid mixed water from the water discharge port 22.

  In FIG. 2, the liquid flow path is narrowed in the middle between the water supply port 21 and the water discharge port 22 to reduce the cross-sectional area, whereby a pressure drop due to the venturi effect occurs in the narrowed portion. In the example of the present embodiment, when the water pressure of the hot water at the water supply port 21 is 150 kpa to 200 kpa, a reduced pressure (negative pressure) of a maximum of 20 mmHg is generated in this constricted portion.

  By this pressure reduction, the air 6 is taken into the ozone gas generator 8 through the air filter 7 and is sucked from the intake port of the aspirator 4 as a mixed gas of ozone gas and air. The sucked mixed gas is mixed into the warm water in a low pressure state, and the warm water is discharged from the water outlet as gas-liquid mixed water.

  Further, the water supply port 21 of the aspirator 4 is provided with inclined blades 24 for rotating the liquid passing therethrough in a spiral manner, whereby the gas-liquid mixed water flows out from the water discharge port 22 while rotating in a spiral shape. .

  Further, a backflow prevention valve 25 is provided at the intake port 23 of the aspirator 4. When the pressure in the constricted portion becomes lower than the pressure in the intake port 23, gas flows from the intake port 23, but the pressure in the constricted portion increases. When this occurs, the backflow prevention valve 25 moves toward the intake port 23 and closes the gas flow path. This corresponds to the check valve 9 described in the ozone gas generator 8.

  The pressure diffusion mixer 10 is a sealed tank in which a cylindrical cavity is placed horizontally. The pressure diffusion mixer 10 has a water supply port connected to the flowing water channel 5 at the center of one circular disk of the cylinder, and a water discharge port at the center of the other disk. Prepare. The internal capacity of this tank is from 500 ml to 1000 ml, and as will be described later, the flow rate of the gas-liquid mixed water is set to 10 to 20 liters per minute. Is double. Further, the diameter (inner diameter) of the water discharge port is set to be the same as or slightly larger than the diameter (inner diameter) of the water supply port so that the tank is not filled with the gas-liquid mixed water. This is because if the tank is filled with gas-liquid mixed water, the flow of hot water in the aspirator 4 is limited, and the function of self-priming the mixed gas does not work sufficiently. In the case of the present embodiment, the diameter of the water outlet is preferably the same as the diameter of the water supply opening.

  About the ozone water shower apparatus comprised as mentioned above, the operation | movement is demonstrated below.

  First, since the hot water does not flow to the aspirator 4 when the manual opening / closing valve 2 is closed, the water flow / water pressure detection switch 3 is turned off, the ozone gas generator 8 does not operate, and self-priming in the aspirator 4 occurs. Since no action occurs, air is not sucked into the air intake.

  Next, when the manual opening / closing valve 2 is opened, since hot water flows to the aspirator 4, the water flow / water pressure detection switch 3 is turned on, and discharge is started by the ozone gas generator 8.

  Next, when warm water flows through the aspirator 4, the outside air (air) 6 passes through the air filter 7 by the self-priming action and is taken into the ozone gas generator 8 to generate ozone gas. The mixed gas of ozone gas and air passes through the backflow prevention valve 9 and is supplied to the intake port of the aspirator 4. And it mixes with warm water in the aspirator 4 and flows out into the water flow channel 5 from the water outlet as gas-liquid mixed water. At this time, the gas-liquid mixed water passes through the flowing water channel 5 while being strongly swirled by the inclined blades in the aspirator 4, and is discharged into the tank of the pressurized diffusion mixer 10.

  FIG. 3 is a view showing the state of the gas-liquid mixed water ejected into the tank of the pressurized diffusion mixer 10 at this time. In addition, (circle) in a figure represents the bubble.

  FIG. 3 (A) shows a state when the gas-liquid mixed water flows from the cavity of the pressurized diffusion mixer 10, and the gas-liquid mixed water flowing from the water supply port 31 is ejected and opposed to the water outlet. It accumulates while swirling in the tank while colliding with the side surface. At this time, the pressure in the tank rises due to ozone gas from the stored air and bubbles.

  FIG. 3B shows a state in which gas-liquid mixed water accumulates in the tank and ozone water in which ozone gas is dissolved is stably discharged from the water outlet. In this state, after the flow of the gas-liquid mixed water flows in from the water supply port, the flow is suddenly slowed down, so that the water pressure when the gas-liquid mixed water is obtained by the aspirator 4 is reduced from 10 kpa to 20 kpa. , Rising from 50 kpa to 100 kpa. And the mixed gas of ozone gas and air refines | miniaturizes by being put under pressure, and the melt | dissolution to warm water advances. Furthermore, since the gas-liquid mixed water flows while rotating in a spiral shape, the time that the bubbles of the mixed gas that are stirred in the tank come into contact with the hot water also increases, so that the solubility of ozone gas in the hot water increases.

  Finally, in a state where the ozone concentration is increased, ozone water as gas-liquid mixed water flows from the water outlet 32 of the pressure diffusion mixer 10 to the shower head 11 through a hose and is discharged.

  As mentioned above, the gas-liquid mixed water of the mixed gas of the ozone gas and the air mixed with the aspirator 4 and the hot water is pressurized in the pressure diffusion mixer 10 and stirred, so that the ozone gas is refined. Dissolution of bubbles in warm water will proceed. As specific numerical values, when the ozone gas concentration generated by the ozone generator 8 is 20 ppm to 60 ppm and the flow rate of hot water is 10 liters to 20 liters per minute, the hot water ozone water concentration at the connecting portion of the shower head 11 is 0.5 ppm. It was able to be -3ppm. This is because the ozone water concentration of hot water under the same conditions when the pressurized diffusion mixer 10 is not provided is 0.1 ppm to 0.5 ppm, so the pressurized diffusion mixer 10 according to the present invention is It shows that there is an effect of increasing the ozone water concentration by about 5 times. In addition, the concentration of this ozone water has cleared 0.5 ppm-2 ppm required for the sterilization effect and the decomposition of polluted organic matter, and the ozone water shower device of the present invention can be used for sterilization and deodorization applications. You can say that.

  Further, the ozone gas concentration released from the shower head 11 as a gas was 1 ppm to 3 ppm when the pressure diffusion mixer 10 according to the present invention was not provided in the shower head 11 portion. In the form, by providing the pressure diffusion mixer 10, it was 0.06 ppm or less, and then rapidly diffused indoors to 0.02 ppm to 0.05 ppm. This indicates that the ozone water permissible concentration of ozone gas is 0.1 ppm or less, so that the ozone water shower apparatus of the present embodiment is safe in use.

  In addition, in this Embodiment, the hot water which heated the tap water from a water supply was used, However, Not only this but the tap water before a heating can also be used.

  Further, in the present embodiment, the gas-liquid mixed water that has passed through the configuration with the inclined blades attached to the aspirator is rotated in a vortex shape. It is also possible to provide a vortex generator composed of a pipe that rotates the gas-liquid mixed water in a vortex.

(Embodiment 2)
FIG. 4 is a configuration diagram of an ozone water shower apparatus according to the second embodiment of the present invention. The difference from the first embodiment is that there is a hand switch 13, and this hand switch 13 is connected in series between the water flow / water pressure detection switch 3 and the ozone generator 8. As a result, the hand switch 13 switches between generating and not generating ozone gas from the ozone generator 8.

  FIG. 5 is a view showing the structure of the hose up to the shower head 11 and the ozone water shower apparatus main body.

  In FIG. 5, the hand switch 13 is attached to the shower head, and the signal line from the hand switch extends to the ozone water shower apparatus main body in an integrated structure along a hose through which ozone water passes. The signal line is separated from the hose in the ozone water shower apparatus main body and connected to the ozone generator 8.

  About the ozone water shower apparatus comprised as mentioned above, the operation | movement is demonstrated below.

  When the hand switch is on, the water flow / water pressure detection switch 3 is turned on when the manual opening / closing valve 2 is opened, and a closed loop formed by the water flow / water pressure detection switch 3 up to the ozone generator 8 and the hand switch 13 is completed. Then, the ozone generator 8 starts operation. Subsequent operations are the same as those in the first embodiment.

  Next, when the hand switch is off, even if the manual opening / closing valve 2 is opened and the water flow / water pressure detection switch 3 is turned on, the closed loop to the ozone generator 8 is not completed, so the ozone generator 8 starts operating. do not do. For this reason, when hot water that has passed through the manual valve 2 flows into the aspirator 4 and a self-priming action occurs in the aspirator 4, only air is supplied from the ozone generator 8.

  Thereafter, air is dissolved in the hot water by the pressure diffusion mixer 10, and the hot water whose air solubility is increased is discharged from the shower head 11.

  As described above, since the hand switch 13 is provided in the shower head 11, the hot water discharged from the shower head 11 can be switched between the ozone water and the hot water having a high air concentration. It is possible to easily switch and use suitable hot water according to the degree of contamination.

  The present invention is useful for an ozone water shower device, and the entire device can be miniaturized, so it can be installed on a washstand in a beauty salon or a hair salon to sterilize hair, hair roots, wash hands of hairdressers, etc. Suitable for deodorizing.
