Description

  The present invention relates to an ozone water cleaning apparatus that sterilizes fingers, in particular, using ozone water in which ozone is dissolved at a high concentration.

Currently, alcohol spray sterilization of fingers before work is most prevalent in medical workers, workers engaged in food processing, and in fields where it is necessary to avoid contamination of microorganisms such as semiconductors and chemicals in clean rooms.
However, as a result of recent microbiological research, many microorganisms that cannot be sterilized by alcohol sterilization have been discovered. Especially, noroviruses that are close to daily life have been announced that alcohol cannot be sterilized, and an innocuous sterilization method is required instead. ing. Of these, ozone water is the most effective.
Currently, the production methods of ozone water that are widely used for industrial use are broadly divided into gas dissolution methods that dissolve in ozone gas generated by discharge, electrolytic gas dissolution methods that dissolve ozone gas generated by electrolysis in water, and raw water directly on the electrolytic surface. Three methods of direct electrolysis (for example, refer patent document 1) which make ozone water by making it contact are utilized.

However, as a commercially available device for sterilizing ozone water on the fingers, a relatively low concentration of ozone water of 1 to 2 ppm flows several minutes per minute and the fingers are immersed in the water flow. The drainage pipe was necessary, and the amount of water supply / drainage was large, so it was extremely inconvenient. An exception is a hand-washing machine for medical use that has been approved for medical use.

In the ozone water cleaning apparatus 200 of the present invention, ozone water is generated in the water tank 1, and the generated ozone water is injected into the dome 2 provided above the water tank 1 and inserted into the dome 2. This is a device for cleaning the object to be cleaned (for example, fingers) S.
A water supply pipe 3 for supplying raw water (for example, water) into the water tank 1 is connected to the upper surface of the water tank 1, and ozone water generated in the water tank 1 is connected to the lower surface of the water tank 1. An outflow pipe 4 that flows out of the water tank 1 is connected. The outflow pipe 4 extends laterally from the lower end side surface of the water tank 1 and is connected to the extrusion pump 5. Further, a pipe 6 such as a tube having a small diameter is connected to the extrusion pump 5, and this pipe tube 6 extends upward and is arranged in a dome part 21 described later. It is connected to the nozzle 7 provided in. The outflow pipe 4, the extrusion pump 5, the piping tube 6 and the nozzle 7 constitute an injection means.

In addition, a dome 2 into which an object to be cleaned S such as a finger is inserted and ozone water is jetted is provided above the water tank 1.
The dome 2 includes a dome portion 21 that protrudes upward, and a support body 22 that closes the lower opening 21 a of the dome portion 21 and supports the dome portion 21. The support body 22 has a truncated cone shape with a hollow inside, and is placed on the upper surface of the water tank 1 and supports the dome portion 21 on the upper surface. A drainage hole 22 a is formed on the upper surface of the support 22 so as to drain the ozone water after passing through the dome portion 21 and washing it. Further, a drain pipe 23 for discharging exhaust ozone water flowing through the support 22 is attached to the side surface of the support 22.

The drainage pipe 23 extends downward from the side surface of the support 22, and a drainage nozzle 23 a is attached to the lower end portion of the drainage pipe 23. Therefore, the waste ozone water after washing in the dome 21 flows through the support 22 through the drain hole 22a, and is further discharged to the outside through the drain pipe 23 from the drain nozzle 23a.
Further, the support 22 is formed with an exhaust port 24a that communicates with the support 22 and exhausts the ozone-containing air in the dome 21. An exhaust fan 24 is attached to the exhaust port 24a. Yes. The exhaust port 24a and the exhaust fan 24 constitute exhaust means. The exhaust fan 24 exhausts the ozone-containing air exhausted through the exhaust port 24a to the outside and decomposes the ozone-containing air with an ozone decomposition catalyst. Examples of the ozone decomposition catalyst include activated carbon honeycombs. That is, ozone is decomposed from the ozone-containing air by passing the ozone-containing air through the activated carbon honeycomb.

  Further, a circular opening 25 penetrating into the dome 21 is formed at the center of the side surface of the dome 21, and the object to be cleaned S can be inserted into the dome 21 from the opening 25. Dryers (air blowing means) 8 are respectively attached to the left and right side surfaces of the dome portion 21, and the object to be cleaned S inserted into the dome portion 21 from the opening portion 21 is washed with ozone water, and then the dryer 8 is The wind for drying is sent.

A nozzle 7 is attached to the inner surface ceiling portion of the dome portion 21, and the nozzle 7 is connected to the tip of the piping tube 6 connected to the water tank 1. Accordingly, the ozone water generated in the water tank 1 flows through the outflow pipe 4 and the piping tube 6 by the extrusion pump 5, and the ozone water is jetted from the nozzle 7.
A dome concentration detecting sensor (concentration detecting means) 9 for detecting the ozone concentration of the ozone water jetted from the nozzle 7 is provided at the lower end of the inner surface of the dome portion 21. The concentration detection sensor 9 in the dome is composed of a detection electrode and a reference electrode that is a reference for potential measurement, a potentiometer that is connected to one end of the detection electrode and the comparison electrode, and measures a potential, although not shown. . Therefore, the tip part (the other end part) of the detection electrode and the comparison electrode is brought into contact with the ozone water sprayed on the cleaning object S, and the potential difference between the detection electrode and the comparison electrode due to the change in the ozone concentration of the detection electrode is detected. Measure.
As the detection electrode, for example, an electrode made of platinum or gold is preferably used, and silver / silver chloride is preferably used as the comparison electrode.
The power supply device 11 to be described later is configured to control the DC voltage between the anode electrode 103 and the cathode electrode 104 so that the ozone concentration thus detected matches a preset ozone concentration. .

  Here, the set concentration is preferably at least 3 ppm or more, and desirably 4 ppm or more. This is because if the concentration is 3 ppm or more, ozone water has bactericidal properties superior to alcohol, and the above-mentioned norovirus can sterilize not only bactericidal fungi but also in a short time. If ozone water with a high concentration of 3 ppm or more is used, the entire surface of the finger can be sterilized if there is an amount of ozone water of several tens ml or at most 100 ml for hand sterilization, and the amount of water supply / drainage can be extremely reduced. This is because the cost can be reduced.

  An LED (lighting means) 10 is attached to the outer surface ceiling portion of the dome portion 21, and the LED 10 is lit according to the ozone concentration detected by the in-dome concentration detection sensor 9. Specifically, the LED 10 is turned on when the ozone concentration has reached a predetermined concentration, and the LED 10 is not turned on when the ozone concentration has not reached the predetermined concentration. Thereby, it can be easily visually confirmed whether or not the ozone water is jetted at a predetermined concentration.

  An insertion detection sensor (not shown) for detecting the insertion of the cleaning object S is provided in the vicinity of the opening 25 of the dome portion 21. When the insertion detection sensor detects the insertion of the object to be cleaned S, ozone water is jetted, and when the object to be cleaned S comes out of the dome portion 21, the dryer 8 is stopped.

On the other hand, a power supply device 11 is provided on the side surface of the lower end of the water tank 1. The power supply device 11 performs overall control of the ozone water cleaning device 200.
For example, in order to generate ozone water in the water tank 1, the raw water is supplied into the water tank 1 as described later, a DC voltage is applied to the catalyst electrode 101, and the agitator is driven. To do. Furthermore, in order to inject ozone water in the dome 21, the drive of various components is controlled. Specifically, by detecting the insertion of the cleaning object S by the insertion detection sensor, ozone water is caused to flow from the inside of the water tank 1 to the outflow pipe 4 for injection, and after a predetermined amount of ozone water is injected, the dryer 8 And the dryer 8 is controlled to stop when the object to be cleaned S comes out of the dome portion 21. Moreover, according to the detection result of the concentration detection sensor 9 in a dome or the below-mentioned concentration detection sensor in a water tank so that the ozone concentration in the dome 2 or the ozone concentration in the water tank 1 becomes a set concentration, Energization is controlled.

  Further, the water tank 1, the support 22, the water supply pipe 3, the drain pipe 23 and the outflow pipe 4, the power supply device 11 and the like are accommodated in the case body 12. The case body 12 is provided with a water level meter 13 for measuring the water level of the ozone water in the water tank 1 so that it can always be confirmed from the outside, and the ozone concentration of the ozone water generated in the water tank 1 is described later. A concentration indicator 14 is attached to detect the concentration in the aquarium and detect the concentration. Further, a power switch 15 for turning on / off the ozone water cleaning apparatus 200 is also provided.

Here, the water tank 1 in which ozone water is generated will be described.
4 is a perspective view of the water tank 1 showing the inside of the water tank 1, FIG. 5 is a side sectional view of the water tank 1, and FIG. 4 to 6, illustration of the water supply pipe 3 and the outflow pipe 4 is omitted.
In the water tank 1, raw water is supplied from the water supply pipe 3 and is filled with raw water, and a catalyst electrode 101 is disposed. Then, by applying a DC voltage to the catalyst electrode 101, ozone bubbles are generated, and the ozone bubbles are dissolved in the raw water to generate ozone water.

  The catalyst electrode 101 has an anode electrode 103 in close contact with one surface of the cation exchange membrane 102 and a cathode electrode 104 in close contact with the other surface. An output terminal 105 from the power supply device 11 is electrically connected between the anode electrode 103 and the cathode electrode 104 so that a DC voltage is applied. That is, the anode electrode 103 and the cathode electrode 104 are connected to the power supply device 105 through the conductive wires to the electrodes 103 and 104. The applied DC voltage is preferably 9 to 15 volts, for example.

  As the cation exchange membrane 102, a conventionally known one can be used, and a fluorine-based cation exchange membrane having a high durability against the generated ozone can be used. For example, a thickness of 100 to 250 microns is preferable.

  The anode electrode 103 and the cathode electrode 104 are not in close contact with each other so as to completely cover the cation exchange membrane 102, and a large number of through holes are provided so that the anode electrode 103 and the cathode electrode 104 are exchanged with the cation. The film 102 is overlapped with a contact portion and a non-contact portion. That is, the anode electrode 103 and the cathode electrode 104 have a grating shape or a punching metal shape. FIG. 6 shows the case of grating. In particular, the cathode electrode 104 is formed to have a coarser mesh than the anode electrode 103. Specifically, the grating shape is a lattice shape in which wires are welded, and the punching metal shape is a porous plate shape in which a large number of through holes are formed in a metal plate.

As the anode electrode 103, a metal having an ozone generation catalytic function is used, and in order to obtain pure ozone water, it is preferable to use an electrode of platinum or a platinum-coated metal. In particular, in the present invention, titanium is coated with platinum. It is preferable to use a metal.
On the other hand, as the cathode electrode 103, it is preferable to use gold, silver, platinum, or titanium metal, and it is particularly preferable to use silver or a metal coated with silver.
The anode electrode 103 is preferably processed from a planar metal into a grating shape. Moreover, as a coating process, it can carry out by plating, electrodeposition, etc., for example.

  By forming the grating-like anode electrode 103 in this way, the intersection of the members constituting the anode electrode 103 is pointed and protrudes to the outer surface to generate a vortex in contact with the water flow, and the fine bubbles of ozone generated at the anode electrode 103 Can be dissolved to accelerate dissolution.

  In the case of a punched metal electrode, since the porous plate is substantially planar, water parallel to the porous plate hardly flows through the porous plate. It is more preferable to use them together.

The cation exchange membrane 102, the anode electrode 103, and the cathode electrode 104 are each formed in an arc shape, and after bringing them into close contact, the catalyst is bonded by an insulating bonding member (not shown). The electrode 101 is used.
The arc-shaped catalyst electrode 101 is fixed in the water tank 1 so that the anode electrode 103 is disposed on the center side of the water tank 1 and the cathode electrode 104 is disposed on the outside.
As a fixing method in the water tank 1, for example, a rod-shaped attachment member (not shown) may be provided at a predetermined position from the inner wall surface of the water tank 1 toward the cathode electrode 104, and may be fixed so as to support it. The mounting member used here is preferably made of an ozone-resistant material. In addition, the catalyst electrode 101 may be directly fixed to the bottom surface of the water tank 1, and is not particularly limited.

Further, the water tank 1 is provided with a rotor 106 and a stirring device for generating a swirling water flow in the water tank 1 toward the center of the cylinder.
As a stirring device, it is preferable to use a magnetic stirrer 107 (shown only in FIG. 5).

A water tank concentration detection sensor (not shown) for detecting the ozone concentration of the ozone water generated in the water tank 1 is provided in the water tank 1. As the concentration detection sensor in the water tank, the same one as the concentration detection sensor 9 in the dome described above can be used.
The power supply device 11 is configured to control the voltage between the anode electrode 22 and the cathode electrode 23 so that the ozone concentration detected by the concentration detection sensor in the tank matches the preset ozone concentration.

Therefore, in the water tank 1 provided with the catalyst electrode 101 as described above, when the rotor 106 is rotated by driving the stirring device, a swirling water flow having a constant speed is generated in the water tank 1, and the anode is driven by driving the power supply device 11. A predetermined voltage is applied between the electrode 103 and the cathode electrode 104. By this energization, the raw material water swirling around the central portion in the water tank 1 comes into contact with the anode electrode 103 to generate oxygen and a large amount of ozone on the anode electrode 103, and the generated ozone water is dissolved in the swirling water flow. To ozone water. In the cathode electrode 104, hydrogen is generated when the raw water swirling on the inner wall surface in the water tank 1 contacts the cathode electrode 104.
In addition, the swirling water flow causes the flow direction to be complicated due to slight unevenness of the anode electrode 103 on the anode electrode 103 side, generating vortex flow, and quickly absorbing ozone bubbles generated on the surface of the cation exchange membrane 102 into water. As a result, ozone water is generated, and a large amount of current flows between the anode electrode 103 and the cation exchange membrane 102.
On the other hand, the flow direction changes depending on the unevenness of the cathode electrode 104 even on the cathode electrode 104 side. However, since the electrode is coarser than the anode electrode 104, the flow direction does not change as complicated as the anode electrode 103. After the hydrogen bubbles generated in 104 become a certain size, they are slowly separated from the cathode electrode 104 and rise to the water surface due to their buoyancy, and are released out of the system as hydrogen gas. It is taken into running water and mixed with ozone water as hydrogen suspension water.

During energization, the concentration of the solution in the water tank 1 is simultaneously measured by the water tank concentration detection sensor, and the ozone concentration between the anode electrode 103 and the cathode electrode 104 of the power supply device 11 is set to a preset ozone concentration. The voltage is controlled.
As described above, ozone water having a set concentration is generated.

Next, the operation of the ozone water cleaning apparatus 200 will be described.
First, when the power switch 15 is turned on, the power supply device 11 is driven, and the raw water is supplied into the water tank 1 through the water supply pipe 3 as described above, and a swirling water flow is generated by the stirring device. The ozone water with the set concentration is generated.
When the object to be cleaned S is inserted into the dome portion 21 through the opening 25, the ozone water is discharged into the outflow pipe 4 by the detection of the insertion detection sensor and is pushed out in the outflow pipe 4 by the push pump 5. It is pushed upward toward the dome 2 and sprayed from a nozzle 7 provided at the tip of the outflow pipe 4. The sprayed ozone water reaches the body to be cleaned S inserted into the dome portion 21, and the body to be cleaned S is cleaned.
The waste ozone water after washing flows into the support 22 below the dome portion 21 through the drain hole 22a, further flows into the drain pipe 23, and is drained to the outside.
Further, at this time, the ozone gas-containing air in the dome portion 21 is exhausted from the exhaust port 24 a and passes through the activated carbon honeycomb of the exhaust fan 24 to be decomposed and exhausted.
Further, when a predetermined amount of ozone water is ejected from the nozzle 7, the dryer 8 is driven, and drying wind is sent into the dome portion 21.

  On the other hand, the ozone water jetted from the nozzle 7 is measured by the in-dome concentration detection sensor 9 and the ozone concentration detected by the in-dome concentration detection sensor 9 reaches a preset ozone concentration. LED 10 is lit, and LED 10 is not lit when the set concentration is not reached. When the set concentration is not reached, the voltage between the anode electrode 103 and the cathode electrode 104 is controlled by the power supply device 11.

  When the object to be cleaned S is taken out from the dome portion 21, the dryer 8 is stopped by the detection of the insertion detection sensor.

As mentioned above, according to embodiment of this invention, the catalyst electrode 101 is provided, the water tank 1 in which ozone water is produced | generated, the dome 2 provided above the water tank 1, and the ozone in the water tank 1 in the dome 2 Since there are provided injection means for injecting water (outflow pipe 4, extrusion pump 5, piping tube 6 and nozzle 7), and an opening 25 formed on the wall surface of the dome 21 and into which the object to be cleaned S is inserted. Then, a DC voltage is applied between the anode electrode 103 and the cathode electrode 104, and by continuously bringing the raw material water into contact with the anode electrode 103, ozone bubbles are generated on the surface of the anode electrode 103 by electrolysis of water, and the surface of the cathode electrode 104 Hydrogen bubbles are generated. Then, the generated ozone bubbles are continuously brought into contact with the raw material water, so that they are surely dissolved in the raw material water and high-concentration ozone water is generated. Further, since the generated ozone water is jetted in the dome 2 by the nozzle 7, it can be cleaned with ozone water in a high concentration state. Moreover, since it is highly concentrated ozone water, it can be washed with a small amount, and the amount of water supply / drainage is extremely small, thereby reducing the cost. Moreover, since the dome 25 into which the to-be-cleaned body S is inserted is provided above the water tank 1, versatility can be improved without taking up a compact space.
Moreover, since the dryer 8 is provided, the to-be-cleaned body S can be dried.
Since the exhaust port 24a and the exhaust fan 24 are provided, the ozone-containing air in the dome 2 is exhausted through the exhaust port 24a, and the ozone-containing air in the exhaust is decomposed by the ozone decomposition catalyst by the exhaust fan 24. Therefore, it is excellent in terms of environmental protection without discharging ozone gas to the outside.

Further, the ozone water cleaning apparatus 200 includes the in-dome concentration detection sensor 9 and the current supply to the catalyst electrode 101 is controlled based on the detected ozone concentration, so that the object to be cleaned is always maintained at a predetermined ozone concentration. S can be washed. In addition, since the LED 10 is lit according to the ozone concentration detected by the in-dome concentration detection sensor 9, it can be easily confirmed whether or not the ozone concentration has reached a predetermined concentration.
Further, since the nozzle 7 is provided on the inner surface ceiling portion of the dome portion 2, the ozone water is allowed to flow from the upper side to the lower side with respect to the cleaning object S inserted in the dome 2, thereby cleaning the object to be cleaned. Ozone water can be reliably sprayed on the entire body S, and the cleaning effect can be improved.

In addition, this invention is not limited to the said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, in the above embodiment, the nozzle 7 for injecting ozone water is provided on the inner ceiling of the dome portion 21 so that the ozone water flows from the upper side to the lower side. You may comprise so that it may provide in the side and it may inject from the downward | lower direction to the upper direction. In addition, the nozzle 7 may be provided on the side surface of the dome portion 21 so as to be ejected from the left and right. Furthermore, the number of nozzles 7 is not limited to one, and a plurality of nozzles 7 may be provided.
Further, although one opening 25 for inserting the object to be cleaned S is provided on the front surface of the dome 21, two openings are formed on the left and right sides of the front, for example, the right hand and the left hand are inserted from each opening. It doesn't matter.
The LED 10 is provided on the outer ceiling of the dome 21 and the LED 10 is turned on only when the ozone concentration reaches a predetermined concentration. However, a plurality of LEDs are provided and the LED 10 is turned on according to the ozone concentration. The number may be changed, or the lighting color of the LED may be changed.
