 Air sanitizer

 Technical field

 [0001] The present invention relates to an air sterilization apparatus capable of removing airborne microbial viruses and the like.

 Background art

 [0002] Conventionally, for the purpose of removing airborne microbial viruses, etc., electrolyzed water mist is diffused in the air (to be sterilized space), and this electrolyzed water mist is brought into direct contact with airborne microorganisms, and viruses, etc. A sterilization apparatus that inactivates the bacteria has been proposed (see, for example, Patent Document 1). Patent Document 1: Japanese Patent Laid-Open No. 2002-181358

 Disclosure of the invention

 Problems to be solved by the invention

 [0003] However, since there is a limit to the space in which the electrolyzed water mist can be diffused, the above sterilization apparatus is effective in a small space in which the electrolyzed mist can be diffused, but it is a large space such as a public facility or vehicle. However, there was a problem that it was difficult to exert its effect.

 [0004] Further, in the conventional sterilization apparatus, since the mist of the electrolyzed water is diffused into the space, a large amount of water is used to generate the mist, and the interior of the space is humidified by the mist. Inconvenience such as clouding occurred.

 [0005] Therefore, the applicant firstly arranged a brace in a floor-standing casing, and has a gas / liquid contact member formed of a material having low reactivity with electrolyzed water! An electrolyzed water dropping means for dropping electrolyzed water into the air and a blower fan for blowing indoor air to the gas-liquid contact member. We developed a floor-standing air sanitizer that blows out from the air outlet provided in the upper part of the housing in contact with the electrolyzed water dropped on the liquid contact member.

[0006] With such a floor-standing air sanitizer, the indoor air sucked from the suction port formed in the lower part of the casing is brought into contact with the electrolyzed water dripped on the gas-liquid contact member, and is placed on the upper part of the casing. Installed outlet force By blowing out, the indoor air sterilized by contact with the electrolyzed water is greatly increased. It became possible to fly far away in space, and air sterilization in large spaces could be performed efficiently.

 However, in such a structure, as one of the electrolyzed water dropping means, the electrolyzed water is conveyed above the gas-liquid contact member in order to drop the generated electrolyzed water onto the gas-liquid contact member. It was necessary to install a special pump for this purpose, which caused problems such as an increase in size and complexity of the device, and an increase in cost.

 [0008] Furthermore, when such an air sterilizer is used in a cold region where the outside air temperature is low, the electrolytic water may freeze. When the electrode is energized in such a state where the electrolyzed water is frozen, an extreme load force S is applied to the electrode, which may significantly reduce the life of the electrode.

[0009] The present invention has been made in order to solve the problems of the related art, and air sterilization in the sterilized space can be performed while simplifying and downsizing the structure of the air sterilization apparatus. The purpose is to do it efficiently.

 [0010] It is another object of the present invention to provide an air sterilization device that prohibits energization of the electrode during freezing of the electrolyzed water and can eliminate the burden on the electrode.

 The invention's effect

 [0027] The air sterilization apparatus of the invention of claim 1 includes a gas-liquid contact member formed of a material that is less reactive with electrolyzed water, and a water storage part that stores the electrolyzed water, and a capillary phenomenon from the water storage part. Since the electrolyzed water is supplied to the gas-liquid contact member using the air and the air ventilated through the gas-liquid contact member is brought into contact with the electrolyzed water, the flow rate of the sterilized air in contact with the electrolyzed water is increased. Air sterilization in the space can be efficiently performed without significant reduction. In addition, since the gas-liquid contact member is made of a material that is less reactive with electrolyzed water, the durability can be improved and the life can be extended.

 [0028] In particular, since the electrolyzed water is supplied from the water reservoir to the gas-liquid contact member using the capillary phenomenon, there is a special pump mechanism for supplying the electrolyzed water from the water reservoir to the gas-liquid contact member. This eliminates the need for simplification and downsizing of the structure and reduction of power consumption. In particular, when a battery is used as the driving power source of the air sterilization apparatus of the present invention, the load on the knotter can be reduced.

 [0029] Further, in the invention of claim 2, since the hydrophilic treatment is performed on the gas-liquid contact member, the hydrophilicity to the electrolyzed water can be enhanced. Thereby, the water retention of the electrolyzed water of the gas-liquid contact member is maintained, and the contact between the air ventilated by the gas-liquid contact member and the electrolyzed water can be maintained for a long time.

[0030] Further, in the invention of claim 3, one end is provided in contact with the gas-liquid contact member, and the other end is provided with a water absorbing member immersed in the electrolyzed water in the water storage section. If scales accumulate on the surface of the parts, they can be easily replaced. . In particular, compared to the case where the gas-liquid contact member is directly immersed in the electrolyzed water in the water reservoir, it is possible to easily achieve a structure that seals the water reservoir and prevents the electrolyzed water in the water reservoir from leaking easily. Countermeasures are easy. In particular, when the air sterilization apparatus of the present invention is used in an inclined condition, it is particularly effective, for example, when traveling on a slope when the air sterilization apparatus is mounted on a vehicle.

 [0031] Further, in the invention of claim 4, since the water absorbing member can be switched between a state immersed in the electrolyzed water in the water storage section and a state separated from the electrolyzed water, the sterilization is not performed. In addition, by separating the water absorbing member, the consumption of the electrolytic water due to natural evaporation can be suppressed. In particular, when the air sterilization apparatus of the present invention is mounted on a vehicle, the temperature inside the vehicle rises to close to + 60 ° C. in summer, so that it is more effective to prevent spontaneous evaporation of electrolyzed water.

 [0032] Further, in the invention of claim 5, since the water storage section has a sealed or semi-sealed structure, the risk of water leakage from the water storage section is significantly reduced. Furthermore, for example, if the water supply port for supplying water into the water storage part is made of a hydrophobic material, the electrolyzed water in the water storage part is less likely to leak to the outside.

 [0033] Further, in the invention of claim 6, when the electrode provided in the water reservoir is energized, the water containing at least saline ions injected into the water reservoir, for example, tap water, is treated electrochemically. Since the electrolyzed water is generated by this, air sterilization can be performed more efficiently, and the pressure in the water storage section is increased by the electrochemical treatment using the electrode. The supply of electrolyzed water to the gas-liquid contact member by capillary action is also facilitated.

 [0034] Further, since the pressure relief mechanism in the water storage section is provided in the invention of claim 7, even when the pressure in the water storage section is excessively increased by the electrochemical treatment using the electrode, this is accurately released. To improve safety.

[0035] Further, in the invention of claim 8, since the water reservoir is filled with the porous material or the water-absorbing polymer material, water leakage from the water reservoir can be more effectively prevented.

[0036] In the invention of claim 9, since the cover that can be opened and closed is provided so that the periphery of the gas-liquid contact member can be opened and closed, the air-liquid contact member is sealed around when air sterilization is not performed. Okuko Thus, consumption due to spontaneous evaporation of the electrolyzed water can be effectively suppressed.

 [0037] Further, in the invention of claim 10, since the air-liquid contact member is provided with the air blowing means, the air-liquid contact member is air-operated by the air blowing means even in the space where the air-flow means is not provided. Ventilation can be efficiently sterilized.

 [0038] According to the invention of claim 11, an electrode that generates electrolyzed water by electrochemically treating water that is energized and contains at least saline ions in the reservoir, for example, tap water, and the electrode In the air sterilization apparatus for sterilizing the electrolyzed water in the water storage section, the control means controls the water in the water storage section with a constant current density applied to the electrodes. If it is determined that the water in the reservoir is frozen based on the voltage value between the electrodes, which varies depending on the temperature, energization of the electrodes is prohibited, so air sterilization can be performed more efficiently. become able to.

 [0039] In particular, when the water in the water storage section is frozen, the voltage between the electrodes is extremely increased, so that an excessive burden is applied to the electrodes. According to the present invention, the control means applies the electrodes to the electrodes. If the current density is constant and the water in the reservoir is determined to be frozen based on the voltage value between the electrodes, which varies depending on the temperature of the water in the reservoir, energization of the electrode is prohibited. Therefore, it is possible to eliminate the burden on the electrode that is generated when the frozen water is electrolyzed and to extend the life of the electrode. In particular, when a battery is used as the drive power source of the air sterilization apparatus of the present invention, it is possible to eliminate the problem that the battery load increases due to the extreme increase in the voltage between the electrodes.

 [0040] According to the invention of claim 12, the control means cancels the prohibition of energization to the electrode when it is determined that the freezing of the water in the water storage section has been eliminated based on the voltage value between the electrodes. After freezing of the water in the department is eliminated, air sterilization can be performed without any trouble.

 [0041] Further, the invention of claim 13 is provided with a thawing means for thawing the water in the water storage section, and the control means is based on a voltage value between the electrodes to a predetermined low temperature or lower before the water in the water storage section freezes. If it is judged that the temperature has dropped, the thawing means is operated. For example, the heater as in claim 14 or the heating of an air conditioner (air conditioner) or the like for heating air as in claim 15 is used. By means, freezing of water in the water reservoir can be avoided as much as possible. Also

If the water in the reservoir is frozen, accelerate thawing and quickly generate electrolyzed water. It becomes possible to be able to do.

 [0042] Further, in the invention of claim 13, since the defrosting means is operated when the voltage value between the electrodes rises above a certain voltage, a special detection means such as a temperature sensor is separately installed in the water reservoir. It will be possible to judge that the water in the reservoir has fallen below the predetermined low temperature before freezing.

 [0043] Furthermore, the invention according to any one of claims 11 to 15, further comprising a gas-liquid contact member made of a material less reactive with electrolyzed water as in the invention of claim 16, and having a water storage part If the electrolyzed water is supplied to the gas-liquid contact member by utilizing capillary action and the air ventilated through the gas-liquid contact member is brought into contact with the electrolyzed water, the sterilized air in contact with the electrolyzed water This makes it possible to efficiently sterilize the air in the space without greatly reducing the flow rate of the air. In addition, since the gas-liquid contact member is formed of a material that is less reactive with electrolyzed water, durability can be improved and a longer life can be achieved.

 BEST MODE FOR CARRYING OUT THE INVENTION

[0044] The present invention is made in order to eliminate the inconvenience that the apparatus becomes complicated and large in an air sterilization apparatus capable of removing airborne microbial viruses and the like. Furthermore, the present invention has been made in order to eliminate the disadvantage that the electrode is subjected to an extreme load and the life is remarkably reduced by energizing the electrode when the electrolyzed water is frozen in the air sterilization apparatus.

Realized. Furthermore, for the purpose of eliminating the burden on the electrode when the electrolyzed water is frozen, it is provided with a control means for controlling the energization to the electrode, and with this control means the current density applied to the electrode is constant, Based on the voltage value between the electrodes, which varies depending on the temperature of the water in the water reservoir, when it is determined that the water in the water reservoir is frozen, this was achieved by prohibiting power to the electrodes. In particular, the present invention makes it possible to efficiently disinfect automobiles such as passenger cars and buses, train cars, and the like.

The body cover 2 is a wall formed by a top panel 2T and four panels (front panel 2A, rear panel B, side panel 2R, and side panel 2L) extending vertically from the outer periphery of the top panel 2T. Consists of

 [0048] On the top surface of the top plate 2T, a plurality of (four in the embodiment) operation switches 11 for control, a display means 12 having a plurality of (two in the embodiment) LED lamp forces, and a power switch An operation unit 10 having 13 is formed. Between the one end of the top plate 2T (the front end in FIG. 1) and the upper end of the front panel 2A, the room air that becomes the sterilization space is evacuated in the air sterilizer VW (in the body strength bar 2). ) Is formed in order to inhale. The side panel 2R located at one end of the front panel 2A and the back panel 2B (the right end of the front panel 2A and the back panel 2B in FIGS. 1 and 2) is sterilized by the gas-liquid contact member 8 The exhaust port 5 for discharging the air to the outside of the air sterilization apparatus VW (the room that is the sterilization space) is formed. This exhaust port 5 is composed of a large number of small holes 5A formed in the vertical direction of the side panel 2R.

 [0049] Further, the front panel 2A of the main body cover 2 has a water amount confirmation for confirming the water level of water containing at least chloride ions stored in the water supply tank 15 (in this embodiment, tap water). A window 16 is formed. With this water amount confirmation window 16, the amount of water in the water supply tank 15 can be confirmed without removing the main body cover 2.

Next, the internal configuration of the air sterilizer VW will be described with reference to FIGS. 2 to 4. FIG. 4 is an internal configuration diagram of the air sterilizer VW with the main body cover 2 removed from the main body 1. [0051] The main body 1 of the air sterilizer VW is a frame body having a receiving surface 1A and a wall surface 1B force extending in the vertical direction (downward) from the outer periphery of the receiving surface 1A, and the lower end of the wall surface 1B. The wall 1B force is formed with an extension 1C that extends outward. The outer periphery of the wall surface 1B is set to be substantially the same as the inner periphery of the main body force bar 2, and the outer periphery of the extended portion 1C is set to be larger than that. When the main body cover 2 is attached to the main body 1, the inner surface of the front end (lower end) of the wall surface of the main body cover 2 comes into contact with the wall surface 1B of the main body 1, so that the main body cover 2 is placed on the upper surface of the extension 1C. It will be held by 1 wall surface 1B.

 [0052] The receiving surface 1A of the main body 1 has communication holes 30, 31, penetrating the receiving surface in the vertical direction (vertical direction) at one end, the other end, and the central portion between the one end and the other end. 32 and 33 are formed. The communication hole 30 formed at one end of the receiving surface 1A is for attaching the water absorbing member 19 to one end of the main body 1, and an engaging portion 30A is formed around the receiving surface 1A so as to stand upward. Has been. A water supply tank 15 for supplying water into the water storage tank 9 as a water storage section is attached to the communication hole 33 formed at the other end of the receiving surface 1A. That is, the communication hole 33 is a water supply port for supplying water (water in the water supply tank 15 in this embodiment) into the water supply tank 9. Also, electrodes 17 and 18 described later are attached to the communication hole 31 in the center of the receiving surface 1A, and a pressure valve 37 is installed in the communication hole 32.

 [0053] This pressure valve 37 is used when the pressure in the water storage tank 9 is excessively increased by a gas (hydrogen, oxygen, etc.) generated by an electrochemical process using electrodes 17 and 18, which will be described later. Functions as a pressure relief mechanism to relieve pressure. The pressure valve 37 has a structure that only allows gas in the water tank 9 to flow outside at a certain pressure or higher without allowing gas from the outside of the water tank 9 to flow into the water tank 9, for example, reverse It consists of stop valves. The pressure valve 37 allows the internal pressure to be released accurately when the pressure in the water storage tank 9 increases too much. Safety can be improved.

Further, an engaging portion 25D for attaching the electrolytic cell tray 25 to the main body 1 is formed on the bottom surface (lower surface) of the receiving surface 1A. This electrolytic cell tray 25 has one end 25A side having a space with a sufficient volume inside, the other end 25B side having a space with a sufficient volume inside, and one end portion. Connect the 25A side and the other end 25B side, and one side (front side) It is a vertically long water receiving member that is formed with a narrow central portion 25C that has a large inner diameter and a small inner volume.

 [0055] The electrolytic cell tray 25 is fitted into the engaging portion 25D having an opening edge at the upper end formed on the bottom surface of the receiving surface 1A of the main body 1. Specifically, the electrolytic cell tray 25 is inserted into the wall surface 1B from below the expansion portion 1C of the main body 1 with the packing 26 as a sealing member attached to the entire periphery of the upper end opening edge of the electrolytic cell tray 25. Then, when the electrolytic cell tray 25 is inserted to a predetermined mounting position, the upper end opening is fitted into the engagement portion 25D, whereby the electrolytic cell tray 25 is attached to the main body 1. The electrolytic cell tray 25 is attached to the main body 1, and the upper end opening is hermetically closed by the receiving surface 1A of the main body 1, and the electrolytic cell tray 25 has a sealed or semi-sealed water storage structure. Tank 9 is formed. In the water storage tank 9, electrolyzed water described later is stored. In the present embodiment, the packing 26 is attached to the entire upper end opening edge of the electrolytic cell tray 35, and is hermetically closed by the receiving surface 1A of the main body, and all the communication holes formed in the receiving surface 1A. Since 30, 31, 32, and 33 are respectively closed by the water absorbing member 19, the electrodes 17, 18, the pressure valve 37, and the water supply tank 15, the water storage tank as the water storage portion has a sealed structure.

By the way, as described above, the central portion of the electrolytic cell tray 25 has a narrow shape with a large front side and a small internal volume, so that the capacity of the electrolytic water stored in the central portion of the water storage tank 9 is reduced. Inevitably less. A water absorbing member 19 provided so as to come into contact with the gas-liquid contact member 8 is attached to the central portion of the water storage tank 9, that is, one end portion of the main body 1 as described above, and the water tank 9 is provided to the other end portion. Since the water supply tank 15 for supplying water is attached, the pair of electrodes 17 and 18 (electrolysis unit) described above are provided in the water storage tank 9 between the water absorbing member 19 and the water supply tank 15. Yes. Electrodes 17 and 18 generate electrolyzed water by electrochemically treating (electrolyzing) water (in this example, tap water) containing at least salt ions stored in the water storage tank 9. It is something to be made. Specifically, the electrodes 17 and 18 are for electrolyzing tap water in the water storage tank 9 by energization from a power source to generate electrolyzed water containing active oxygen species, and the upper end is an electrode terminal. Connected to 52 and 53. The electrode terminals 52 and 53 are connected to the control means C described later, and the electrodes 17 and 18 are energized through the electrode terminals 52 and 53 from here. [0057] Here, the reactive oxygen species are oxygen molecules having higher oxidative activity than normal oxygen and related substances, such as superoxide-on, singlet oxygen, hydroxy radical, or In addition, so-called active oxygen in a narrow sense such as hydrogen peroxide or hydrogen peroxide includes so-called active oxygen in a broad sense such as ozone or hypohalous acid.

[0058] The electrodes 17 and 18 are electrode plates in which, for example, the base is Ti (titanium), the coating tank is configured with Ir (iridium), and Pt (platinum) force, and the current value applied to the electrodes 17 and 18 is Given a current density of 20 mA (milliamps) / cm ² (square centimeters), a given suspended residual chlorine concentration (eg, lmg (milligrams) / \ (liters)) is generated.

 [0059] When the tap water is energized by the electrodes 17, 18, the force sword electrode

 4H + + 4e— + (40H—) → 2H + (40H—)

 2

 And the anode electrode

 2H 0 → 4H + + 0 + 4e—

 twenty two

 At the same time, the salt and salt ions contained in the water (pre-added to tap water)

 2C1— → C1 + 2e "

 2

 Then, this C1

 2 reacts with water,

 CI + H 0 → HC10 + HC1

 It becomes. As shown in the above chemical formula, the aforementioned gas such as hydrogen and oxygen is generated by the electrochemical treatment using the electrodes 17 and 18.

In this configuration, HCIO (hypochlorous acid) having a high sterilizing power can be generated by energizing the electrodes 17 and 18. The electrolyzed water containing hypochlorous acid is supplied to the gas-liquid contact member 8 through the water-absorbing member 19 due to capillary action, and the propagation of germs on the gas-liquid contact member 8 can be prevented, and the gas-liquid contact member 8 Viruses floating in the air passing through can be inactivated. Further, when the bad odor passes through the gas-liquid contact member 8, it reacts with hypochlorous acid in the electrolytic water, and is ionized and dissolved to be removed from the air and deodorized. In particular, the central portion of the water storage tank 9 in which the electrodes 17 and 18 are disposed as described above has a narrow shape with a small internal volume, and the capacity of the stored tap water is small. Electrolysis can produce electrolyzed water of high concentration (ie, high concentration of hypochlorous acid). it can.

 [0061] As shown in Figs. 5 and 6, the electrodes 17 and 18 are surrounded by an electrode fixing plate 54 so that the surfaces of both electrode plates face each other at a predetermined interval. Is fixed. A protrusion 54A having substantially the same shape as the communication hole 31 of the main body 1 described above is formed at the upper end of the electrode fixing plate 54, and the protrusion 54A is engaged with and held by the inner surface of the communication hole 31. Attached to the main unit 1. Specifically, when the electrode fixing plate 54 to which the electrodes 17 and 18 are fixed is inserted into the communication hole 31 from the bottom surface (lower side) of the receiving surface 1A, the protrusion 54A formed at the upper end is connected to the communication hole 31. Thus, the protrusion 54A is held by the inner wall surface of the communication hole 31 and attached to the main body 1.

 [0062] At this time, in order not to disturb the flow of the electrolyzed water in the water storage tank 9, that is, the tap water supplied from the other end side (water supply tank 15) of the main body 1 to the water storage tank 9 is supplied to the electrode 17, 18 and the plate surfaces of the electrodes 17 and 18 provided so as to face each other so that the electrolyzed water generated by the electrodes 17 and 18 can smoothly flow to the one end side (gas-liquid contact member 8). The other side force is also attached to the water storage tank 9 so as to be parallel to the flow direction of the electrolyzed water in the water storage tank 9. In addition, the electrodes 17 and 18 are attached to the main body 1, and at least the tip (lower end) is immersed in the electrolyzed water in the water storage tank 9.

The blower 20 is a blowing means for ventilating the gas-liquid contact member 8 and is configured to introduce air from the outside (indoor), supply the gas-liquid contact member 8, contact it, and then discharge it to the outside. ing. The blower 20 is provided at the center of the rotation axis of the blower fan 21 and the blower fan 21, and is provided on one side (front side in FIG. 2) on which the fan motor 22 that rotationally drives the blower fan 21 and the front panel 2A are located. A fan intake port 23A is formed at the center, and a fan casing 23 is formed with a fan exhaust port 23B formed at a lower portion on one end side (the right end side in FIG. 2) where the side panel 2R is located. The blower 20 of the present embodiment is configured by a sirocco fan that sucks air and discharges it in the radial direction as well as the direction force of the shaft around which the blower fan 21 rotates.

[0064] The blower 20 is arranged such that the fan intake port 23A is positioned on the front panel 2A side and the fan exhaust port 23B is positioned on the side panel 2R side, and the outer periphery is fixed to the fixed plate (the first fixed plate 40 and the first fixed plate 40). 2 is attached to the upper surface of the central portion of the receiving surface 1A of the main body 1 in a state surrounded by the fixed plate 45).

 [0065] The fixing plate includes a first fixing plate 40 located on one side (front side) of the blower 20 and a second fixing plate 45 located on the other side (back side). The first fixing plate 40 includes a plane 41 arranged in parallel on one side (front side) of the blower 20, a peripheral wall portion 42 extending from the plane 41 toward the blower 20, and one end of the plane 41 (in FIG. 4). A holding surface 8A for extending the gas-liquid contact member 8 and extending horizontally from the plane 41 from the right end). A circular hole 41A is formed in the plane 41 of the first fixing plate 40 at a position corresponding to the fan air inlet 23A formed in the fan casing 23 of the blower 20. Further, a concave portion (not shown) that fits with a convex portion formed on a second fixing plate 45 described later is formed at the tip of the peripheral wall portion 42 located above the plane 41.

 [0066] The second fixing plate 45 includes a flat surface 46 arranged in parallel on the other surface side (rear surface side) of the blower 20, a peripheral wall portion 47 extending from the outer peripheral edge of the flat surface 46 to the blower 20 side, and a flat surface 46. It extends horizontally from one end (right end in FIG. 4) to the flat surface 46, and is constituted by a holding surface 8B for fixing the gas-liquid contact member 8. A convex portion (not shown) that fits the concave portion is formed on one end side of the lower portion of the peripheral wall portion 47 located above the flat surface 46. Further, it is one end side (the left end side in FIG. 3, that is, the gas-liquid contact member 8 side) on the side (blower 20 side) on which the peripheral wall portion 47 of the flat surface 46 extends. The air duct that supplies air discharged from the fan exhaust port 23B to the gas-liquid contact member 8 over one end, which is the gas-liquid contact member 8 side, is also located where the fan exhaust port 23B is located. The partition plates 48A and 48B are attached. Further, fins 49 for adjusting the wind direction of the air discharged from the fan exhaust port 23B are attached to the partition plate 48B attached below.

In order to mount the blower 20 on the main body 1, first, the hole 41 A formed in the flat surface 41 on one end side of the blower 20 and the fan inlet 23 A of the fan casing 23 of the blower 20 are positioned. In addition, the first fixing plate 40 is arranged. Next, the second fixing plate 45 is disposed from the other end side of the blower 20. At this time, if the tip of the peripheral wall portion 47 of the second fixing plate 45 is disposed so as to abut on the tip of the peripheral wall portion 42 of the first fixing plate 40, the inside of the concave portion formed above the peripheral wall portion 42 will be described. The convex part of the peripheral wall part 46 is fitted to the fan 20, so that the blower 20 is fixed to the fixing plates 40 and 45. It will be in the state enclosed in the space formed. In this state, both the fixing plates 40, 45 are screwed from the back side of the second fixing plate 45, and both the fixing plates 40, 45 and the main body 1 are fixed by screwing or the like. Can be attached to.

 By the way, the gas-liquid contact member 8 described above is a member for bringing the electrolytic water stored in the water storage tank 9 into contact with the ventilation air from the blower 20, and is disposed on one end of the main body 1. The The gas-liquid contact member 8 of the present embodiment is a filter member having a her cam structure, and has a structure in which a wide area of gas-liquid contact is secured, water can be retained, and clogging is difficult. That is, the gas-liquid contact member 8 is formed in a har-cam shape as a whole by joining a material 8M bent in a wave shape and a flat material 8P as shown in FIG.

 [0069] These materials 8M and 8P include materials that are less reactive to electrolyzed water, that is, materials that are less deteriorated by electrolyzed water, such as polyolefin resin (polyethylene resin, polypropylene resin, etc.), PET Materials such as (polyethylene terephthalanol) resin, chlorinated bulu resin, fluorine-based resin (PTFE, PFA, ETFE, etc.), cellulosic materials or ceramic materials are used. Thus, by forming the gas-liquid contact member 8 with a material that is less reactive with the electrolyzed water, the durability of the gas-liquid contact member 8 can be improved. In addition, the gas-liquid contact member 8 is subjected to a hydrophilic treatment to increase the hydrophilicity with respect to the electrolyzed water, thereby maintaining the water retention (wetability) of the electrolyzed water of the gas-liquid contact member 8. Therefore, the contact between the air ventilated through the gas-liquid contact member 8 and the electrolyzed water can be maintained for a long time. Furthermore, a plate member 8C having excellent corrosion resistance is attached to the top and bottom surfaces of the gas-liquid contact member 8.

[0070] Furthermore, the gas-liquid contact member 8 is disposed close to the water storage tank 9 (in the present embodiment, the gas-liquid contact member 8 is disposed on the water storage tank 9 as described above), and tap water The electrolyzed water containing the active oxygen species generated by electrolyzing the water is configured to be supplied to the gas-liquid contact member 8 quickly by utilizing the capillary phenomenon by the water absorbing member 19.

[0071] The water absorbing member 19 is for sucking electrolyzed water from the water storage tank 9 and supplying it to the gas-liquid contact member 8. For example, water absorbing member such as non-woven fabric or sponge made of acrylic fiber or polyester fiber is used. The water-absorbing member 19 of the embodiment is formed in a vertically long cylindrical shape, and one end (the upper portion in FIGS. 2, 3 and 7) is the gas-liquid contact member 8. And the other end (the lower part in FIGS. 2, 3 and 7) enters the water storage tank 9 through the communication hole 30 of the receiving surface 1A, and the electrolyzed water in the water storage tank 9 enters. Soaked in Reference numeral 34 denotes a packing as a sealing material provided on the receiving surface 1A around the communication hole 30 and is in contact with the water absorbing member 19.

[0072] Further, as described above, the water supply tank 15 is attached to the communication hole 33, and the water (tap water) stored in the water supply tank 15 is supplied to the water storage tank 9 through the communication hole 33. It is configured to be possible. Further, a water level sensor 75 (see FIG. 8; not shown in FIGS. 1 to 6) for detecting the level of the electrolyzed water stored in the water tank 9 is provided in the water tank 9.

 [0073] Further, in the air sterilization apparatus VW of the present embodiment, the electrodes 17 and 18 are energized periodically by the control means C, for example, once every 3 hours, and electrolyzed for a predetermined time, for example, 10 minutes to 1 hour. Is configured to be executed. In addition, the control means C keeps the current density applied to the electrodes 17 and 18 constant so that the concentration of hypochlorous acid in the electrolyzed water stored in the storage tank 9 is 2PPM to 10PPM. A voltage is applied between 17 and 18. The control means C is a control device that controls the air sterilization apparatus VW of the present embodiment, and is configured by a general-purpose microcomputer or the like. As shown in FIG. 8, the electrodes 17 and 18 (electrolysis unit), the blower 20, the water level sensor 75, the heater 92 described later, and the like are connected to the control board of the control means C. Although not shown in FIG. 8, the control board includes operation switches 11 for controlling the operation unit 10 formed on the top plate 2T of the main body cover 2, display means 12 including LED lamps, and a power switch. 13 is also connected.

 Furthermore, the control board of the control means C of the embodiment is also connected to, for example, the air conditioner 100 of the passenger car 130 to which the air sterilizer VW is attached. The air conditioner 100 is provided with a temperature sensor 101 that detects the temperature in the passenger compartment (see FIG. 8). As a drive power source for the air sterilizer VW, a primary battery such as a dry battery, a secondary battery that can be charged and discharged, and a solar battery that is used in combination with the secondary battery can be applied. You can also use the cigar socket of passenger car 130 to connect to the battery.

[0075] The control means C controls the energization of the electrodes 17 and 18, the operation of the blower 20, the energization of the heater 92, etc., based on the output of the operation switch 11, the power switch 13 and the temperature sensor 101, etc. ing. Further, the control means C displays the flooding on the display means 12 when it becomes empty based on the level of the electrolyzed water stored in the water storage tank 2 detected by the water level sensor 75. , Energization of electrodes 17 and 18 is prohibited.

Next, the operation of the air sterilizer VW of the present embodiment with the above configuration will be described. First, when the power switch 13 of the operation unit 10 formed on the top plate 2T of the main body cover 2 is pressed and the power is turned on, the control means C starts energizing the electrodes 17 and 18. Thereby, the tap water stored in the water storage tank 9 is electrolyzed to generate electrolyzed water containing hypochlorous acid (electrochemical treatment).

 Further, the control means C starts the blower 20 simultaneously with energization of the electrodes 17 and 18. As a result, air in the sterilized space (vehicle interior) sucked from the intake port 4 sequentially passes through the blower 20 and the gas-liquid contact member 8 and forms an air path that is discharged from the exhaust port 5. That is, the air in the sterilized space sucked from the suction port 4 is sucked into the blower 20 from the fan suction port 23A formed on the front side of the fan casing 23 in the axial direction in which the blower fan 21 rotates. Is done. Then, the air is discharged from a fan exhaust port 23B formed in the lower portion of one end side of the fan casing 23 in the radial direction of the blower fan 21, and the air formed on the air discharge side of the fan exhaust port 23B. Ventilation is supplied to the gas-liquid contact member 8 through the duct 48.

 The air from the sterilized space supplied to the gas-liquid contact member 8 comes into contact with hypochlorous acid soaked in the gas-liquid contact member 8. This hypochlorous acid has the function of destroying and eliminating (removing) the surface proteins (spikes) of influenza virus essential for infection when, for example, influenza virus enters the indoor air. Influenza virus and the receptor of the infected organism (receptor) necessary for infection with this virus will not be bound, thereby preventing infection. The sterilized air that has passed through the gas-liquid contact member 8 is discharged to the outside (in the vehicle compartment) from the exhaust port 5 of the side panel 2R provided at one end of the gas-liquid contact member 8.

[0079] According to the air disinfecting apparatus VW of the present invention described in detail above, the electrolyzed water generated by electrolysis by energization of the electrodes 17 and 18 and stored in the water storage tank 9 is utilized by utilizing capillary action. Quickly supply to gas-liquid contact member 8 through water-absorbing member 19, and electrolyze with gas-liquid contact member 8. By bringing water into contact with the ventilation air from the blower 20, the flow rate of the air sterilized by contact with the electrolyzed water is not greatly reduced, so that the air in the sterilized space (vehicle compartment) can be efficiently used. Can be sterilized. Further, since the gas-liquid contact member 8 is made of a material that is less reactive with the electrolyzed water, durability can be improved and a longer life can be achieved.

 [0080] In particular, the air sterilization apparatus VW of the present invention is configured to supply the electrolyzed water in the water storage tank 9 to the gas-liquid contact member 8 by the water absorption member 19 using the capillary phenomenon. As a result, it is possible to supply the electrolyzed water in the water storage tank 2 to the gas-liquid contact member 8 without installing a special pump mechanism or the like for supplying the electrolyzed water to the gas-liquid contact member 8 as in the prior art. As a result, the structure can be simplified and miniaturized, and is particularly effective when mounted on the passenger car 130. Further, since the pump mechanism is not required, the power consumption for driving the pump mechanism is eliminated, so that the power consumption can be reduced. In particular, when a knotter is used as the driving power source of the air sterilizer VW, the load on the battery can be reduced.

 [0081] Further, the air sterilization apparatus VW of the present embodiment electrochemically treats tap water injected into the water storage tank 9 by energization of electrodes 17 and 18 provided in the water storage tank 2. Thus, the electrolyzed water is generated, so that it is always possible to perform air sterilization more efficiently with fresh electrolyzed water, and the electrochemical treatment using the electrodes 17 and 18 can be performed. Since the pressure in the water storage tank 9 increases due to the gas (hydrogen and oxygen) generated in this way, the supply of electrolyzed water to the gas-liquid contact member 8 by capillary action via the water absorbing member 19 is forced and smooth. Will come to be.

Further, in the air sterilization apparatus VW of the present embodiment, the water storage tank 9 is provided by the water absorbing member 19 whose one end is in contact with the gas-liquid contact member 8 and whose other end is immersed in the electrolytic water of the water storage tank 9. Therefore, when scale or the like is deposited on the surface of the gas-liquid contact member 8, the gas-liquid contact member 8 is directly placed in the water storage tank 9. The gas-liquid contact member 8 can be easily replaced as compared with the case where it is immersed in electrolyzed water. In particular, in order to supply the electrolyzed water from the water storage tank 9 to the gas-liquid contact member 8, it is only necessary to form the communication hole 30 in the water storage tank 9 through which the water absorption member 19 can pass. Compared to the case where the water is directly immersed in the electrolyzed water in the water storage tank 9, the water storage tank 9 is sealed. Can be easily achieved.

 That is, the water storage tank 9 of the present embodiment is configured by being hermetically attached to the main body 1 via the packing 26 at the upper end opening edge of the electrolytic cell tray 25, and on the receiving surface 1A of the main body 1. The formed communication holes 30, 31, 32, and 33 are also hermetically closed by the water absorbing member 19, the electrode fixing plate 54 that fixes the electrodes 17 and 18, the pressure valve 37, and the water supply tank 15, respectively. The water storage tank 9 has a hermetically sealed structure, so that the water tank 9 can be easily sealed to prevent water leakage. In particular, such a structure is more effective when the air sanitizer VW is used in an inclined condition, such as when running on a slope when the air sanitizer VW is mounted as in this embodiment.

 [0084] In addition, the conventional circulation type apparatus that returns the electrolyzed water brought into contact with the gas-liquid contact member 8 back to the water storage tank 9 has a structure capable of recovering at least the electrolyzed water excessively supplied to the gas-liquid contact member. As a result, the structure has become complicated, the size of the equipment has increased, and the cost has risen. However, in the present invention, since the electrolyzed water in the water storage tank 9 is supplied to the gas-liquid contact member 8 by the water absorption member 19 using the capillary phenomenon, the electrolyzed water supplied to the conventional gas-liquid contact member is recovered. Therefore, the water path and structure can be simplified and the size can be reduced. Furthermore, the sealing property of the water storage tank 9 can be further improved by making the water storage tank 9 a sealed structure.

 [0085] The air sanitizer VW of the present embodiment described in detail above has a structure in which the water in the water storage tank 9 hardly leaks as described above. It is extremely suitable for vehicles. FIG. 9 is a view showing an arrangement example when the air sterilization apparatus VW of this embodiment is mounted on a passenger car 130. As shown in this figure, the air sanitizer VW is provided on the air outlet 100 of the air conditioner 100 provided on the dashboard 136 (P1), the rear seat 132 (P2), or the driver seat 131. It can be placed in various places such as P3). At this time, the air disinfection device VW is provided with the blower 20 that ventilates the gas-liquid contact member 8 as in this embodiment, so that the top of the dashboard 136 (P1) and the rear seat 132 can be A fan (air blowing means) such as the rear side (P2) is provided, and can be freely installed in a space.

[0086] Further, since the conventional sterilization apparatus diffuses the mist in the space, the mist is emptied by the mist. The interior was humidified and the windshield 135 was cloudy, which could hinder driving, making it unsuitable for installation in automobiles. However, in the air disinfecting apparatus VW of the present invention, inconvenience due to humidification in the passenger compartment can be greatly reduced as compared with the apparatus that diffuses such mist.

 [0087] When the air sterilization apparatus VW is mounted on a vehicle (on-board) as in this embodiment, the electrodes 17 and 18 are periodically energized, so that the control means C senses vibration. A sensor may be connected, and the electrodes 17 and 18 may be energized by sensing vibration caused by the movement of the vehicle. Alternatively, when a solar cell is used, the system may be operated when the vehicle is stopped. Even in this case, the electrochemical treatment is performed for a predetermined time (10 minutes to 1 hour) as described above. Thereafter, the control means C stops energizing the electrodes 17 and 18. Then, the control means C energizes the electrodes 17 and 18 every predetermined time interval, for example, every 3 hours, so as to maintain the concentration of hypochlorous acid in the electrolyzed water stored in the water storage tank 9 at 2PPM to 10PPM. Repeat the electrochemical treatment.

 [0088] Further, the air disinfecting apparatus VW of the present invention is not limited to being installed in the vehicle interior as shown in Fig. 9, but can of course be installed and used in a normal room. Needless to say, it can be sterilized efficiently.

 By the way, when the air sterilization apparatus VW described above is used in a cold area where the outside air temperature is low, for example, when a cold area is visited by an automobile, the electrolyzed water (or water path) in the water storage tank 9 is used. Water) may freeze. When the electrodes 17 and 18 are energized with the electrolyzed water in the water storage tank 9 frozen as described above, the electrodes 17 and 18 are subjected to an extreme load force, and the life of the electrodes 17 and 18 may be significantly reduced.

FIG. 10 is a diagram showing the relationship between the temperature and the voltage of water when the current density applied to the electrodes 17 and 18 is constant. As shown in Fig. 10, when the current density is constant, the higher the temperature of the water in the water storage tank 9, the higher the voltage as the temperature decreases and the temperature decreases. In particular, in Figure 10, when the temperature of the water is in the range of + 20 ° C or higher to around + 5 ° C, the voltage rise accompanying the decrease in temperature is a gentle force.When the temperature drops below + 5 ° C, the voltage rises sharply. If the temperature of the water in the water storage tank 9 drops to near the freezing point (around 15 ° C), the amount of increase in voltage will increase further, and the voltage will increase significantly when the temperature falls below the freezing point. Recognize. In FIG. 10, the freezing point is not more than o ° c (that is, the freezing point is lowered) because the water is not pure water but electrolyzed water containing ions.

 [0091] This increase in voltage is thought to be due to the fact that each ion motion in water becomes dull due to a decrease in temperature, and accordingly, electron transmission (electrical flow) hardly occurs. Furthermore, frozen water (ice) further suppresses the movement of ions, and at the same time increases the contact resistance due to the decrease in the contact area with the electrodes 17 and 18 due to crystallization. This is expected to rise further. In Fig. 10, the power rises around + 4 ° C, where water actually starts to crystallize. Therefore, it is considered that it is possible to know the state of the water in the water storage tank 9 by increasing the voltage using such properties.

 Therefore, the control means C of the air sterilization apparatus VW of the present embodiment changes according to the temperature change of the water in the water storage tank 9 with the current density applied to the electrodes 17 and 18 being constant. If it is determined that the water in the water storage tank 9 is frozen based on the voltage value between the electrodes 17 and 18, energization of the electrodes 17 and 18 is prohibited and the operation of the air sterilizer VW is stopped. If it is determined that the water in the water storage tank 9 has been frozen, the prohibition of energization of the electrodes 17 and 18 is canceled and the air sanitizer VW is operated.

 [0093] Further, in the air sanitizer VW of the present embodiment, the water in the water storage tank 9 is added to the water storage tank 9.

 A heater 92 is installed as a thawing means for thawing (ice), and the control means C controls the temperature below the predetermined low temperature before the water in the water storage tank 9 is frozen based on the voltage value between the electrodes 17 and 18. When it is judged that the water has dropped, the heater 92 is operated to heat the water in the water storage tank 9 by calorie.

Here, the control operation of the air sterilizer VW and the heater 92 by the control means C will be specifically described with reference to the flowchart shown in FIG. In this embodiment, the water in the water tank 9 is a predetermined low temperature before the water in the water tank 9 is frozen. Specifically, in this embodiment, the voltage between the electrodes 17 and 18 increases as the temperature decreases. At a predetermined low temperature (for example, + 5 ° C) that becomes steep (in this case, the voltage value is VB) and at a temperature at which water in the water tank 9 freezes (for example, -5 ° C) The voltage (in this case, the voltage value is VA) is measured in advance, and information on these voltage values VA and VB is input to the control means C. The control means C is connected to the heater 92 based on the voltage value VB. While controlling energization, based on the voltage value VA, Air sterilizer vw is controlled.

 [0095] Specifically, the control means C of this embodiment controls the energization of the heater 92 with a hysteresis width a above and below the voltage value VB. That is, the control means C energizes the heater 92 when the voltage between the electrodes 17 and 18 rises above VB + α, and stops the heater 92 when the voltage drops below VB−α. The control means C controls the operation of the air sanitizer VW (energization of the electrodes 17 and 18) with a hysteresis width | 8 above and below the voltage value VA. That is, when the voltage between the electrodes 17 and 18 rises to VA + j8 higher than the above VB (VB + α), the control means C stops the air sterilizer VW and the voltage becomes VA− β (VA -When β> VB + α), the air sanitizer VW is activated.

 [0096] First, when the power of the air sterilizer VW is turned on (ON) or when the previous power passing time of the electrodes 17 and 18 has elapsed (for example, 3 hours described above), the control means C Turn on the switch at S 1 and proceed to step S 2 to reset flag 1 (FLAG 1) and flag 2 (FL AG2).

 Next, the control means C moves to step S3 and determines whether or not the flag 1 is reset. In this case, since the flag l (FLAGl) has been reset in step S2 described above, the control means C moves to step S4, detects the voltage between the electrodes 17 and 18, and this voltage value V is It is determined whether or not VB + α or more (that is, V≥VB + α). At this time, if the voltage value V is lower than VB +, that is, if V≥VB + is not satisfied, the control means C moves to step S9 and stops the heater 92 (in this case, the heater 9 2 is maintained), and the process proceeds to step S10.

 Then, the control means C determines whether or not the flag 2 is reset in step S10. At this time, since the flag 2 (FLAG2) is reset in the above-described step S2, the control means C moves to step S11, and the voltage between the electrodes 17 and 18 is not less than the VA + β (that is, V It is determined whether or not ≥VA + j8). Here, as described above, since the voltage value V is lower than VB + α, that is, lower than VA + | 8, the control means C moves to step S16 and starts energizing the electrodes 17 and 18. Then, operate the air sanitizer VW.

[0099] After operating the air sterilizer VW in step S16, the control means C returns to step S3 again, moves to step S4, and repeats the above-described operation. [0100] On the other hand, when the voltage V rises to VB + a or more (here, the voltage V is assumed to be VA-β or less), the control means C shifts from step S4 to step S5 and sets flag 1. After that, proceed to Step S6. Then, the control means C activates the heater 92 in step S6. As a result, energization of the heater 92 is started, and the water in the water storage tank 9 is heated.

 [0101] Next, the control means C proceeds to step S10, and determines whether or not the flag 2 is reset. At this time, since the flag 2 (FLAG2) remains reset in the above-described step S2, the control means C moves to step S11, and the voltage between the electrodes 17 and 18 is equal to or higher than the VA + β (that is, It is determined whether or not the force is V≥VA + j8). Here, as described above, the voltage value V between the electrodes 17 and 18 is VB + a or more and lower than VA + β. Therefore, the control means moves to step S16, and the air sanitizer VW is operated. That is, the air sterilizer VW is continuously performed. After that, the control means C returns to step S3 again and determines whether or not the flag 1 is reset.

 [0102] At this time, since the flag 1 is set in step S5 as described above, the control means C moves to S7 and the voltage between the electrodes 17 and 18 is less than or equal to the VB- Judge whether. At this time, since the voltage value V is equal to or higher than VB + a and lower than VA + β as described above, the control means C next proceeds to the step S6 and maintains the state where the heater 92 is operated. Then, the process proceeds to step S10, and the above-described operation is repeated.

 [0103] In this way, the control means C operates the heater 92 when it is determined that the water in the water storage tank 9 has dropped below a predetermined low temperature before freezing based on the voltage value V. As a result, the water in the water storage tank 9 can be heated, so that freezing of the water in the water storage tank 9 can be avoided as much as possible.

 [0104] When the water in the water storage tank 9 is heated by the energization of the powerful heater 92 and the voltage between the electrodes 17 and 18 becomes VB-α or less, the control means C moves from step S7 to step S8. After resetting flag 1 again, go to step S9. Then, the control means C stops the heater 92 at step S9. Thereafter, the control means C moves to step S10 and repeats the above-described operation.

[0105] On the other hand, when the switch is turned on in step S1, the water in the water storage tank 9 has already been frozen. In other words, the case where the voltage value V is higher than VA + β will be explained. In this case, the control means C resets the flag l (FLAGl) and flag 2 (FLAG2) in step S2 as described above, and then proceeds to step S3 to determine whether or not the flag 1 is reset. To do. Since flag 1 (FLAG1) has been reset in step S2 described above, control means C moves to step S4, detects the voltage between electrodes 17 and 18, and this voltage value V is It is determined whether VB + α is greater than or equal to (ie, V≥VB + α).

 [0106] At this time, since the voltage between the electrodes 17 and 18 is VA + β or higher and higher than VB + α, the control means C moves to step S5, sets flag 1, and then proceeds to step S6. Move to. Then, the control means C operates the heater 92 in step S6. As a result, energization of the heater 92 is started, and the water in the water storage tank 9 is heated.

 Next, the control means C proceeds to step S 10 and determines whether or not the flag 2 is reset. At this time, since the flag 2 (FLAG2) has been reset in the above step S2, the control means C moves to step S11, and the voltage between the electrodes 17 and 18 is not less than the VA + β (that is, V ≥ Judge whether or not it is VA +). Here, as described above, since the voltage value V between the electrodes 17 and 18 is not less than VA + β, the control means C shifts to step S12, sets flag 2, then shifts to step 13, and the electrodes 17 , Prohibit energization of 18 and stop the air disinfection device VW.

 [0108] Thereafter, the control means C returns to step S3 again, and determines whether or not the flag 1 is reset. At this time, since the flag 1 is set in step S5 as described above, the control means C moves to step S7 and determines whether or not the voltage between the electrodes 17 and 18 is equal to or less than the VB-α. To do. At this time, since the voltage value V is equal to or greater than VA + β as described above, that is, VB− is greater than the control value C, the control means C proceeds to step S6, maintains the operating state of the heater 92, and proceeds to step S10. Transition to determine if flag 2 is reset or not

Here, since the flag 2 is set in the above-described step S12, the control means C moves to step S14, and whether or not the voltage between the electrodes 17 and 18 is VA− | 8 or less. Determine whether. At this time, since the voltage value V is not less than VA + β as described above, the control means C is Shift to step SI3, maintain the air sterilizer VW stopped, return to step S3, and repeat the above operation.

 [0110] As described above, when it is determined that the water in the water storage tank 9 is frozen based on the voltage value V, the control means C prohibits energization of the electrodes 17 and 18 and removes air. Since the operation of the fungus device VW is stopped, the burden on the electrodes 17 and 18 generated when the above-described ice is electrolyzed can be eliminated. This makes it possible to extend the life of the electrodes 17 and 18. Further, in this case, thawing of the ice in the water storage tank 9 can be promoted by heating the inside of the water storage tank 9 with the heater 92.

 [0111] When the ice in the water storage tank 9 melts due to the energization of the powerful heater 92 and the voltage between the electrodes 17 and 18 drops below VA-β, the control means C starts from step S14 to step S1 5 And after resetting flag 2, move to step S16. Then, the control means releases the prohibition of energization of the electrodes 17 and 18 in step S16, and operates the air sterilizer VW.

 [0112] Then, the control means C returns to step S3, moves to step S7, and repeats the above-described operation. Further, the water in the storage tank 9 is then heated by the heater 92, the temperature of the water rises, exceeds the predetermined low temperature (for example, + 5 ° C) before the water freezes, and the voltage value V becomes VB — When α is less than or equal to α, the control means C proceeds from step S7 to step S8, resets flag 1, and then proceeds to step S9. Then, the control means C stops the heater 92 at step S9.

[0113] As described above, when the freezing of the water in the water storage tank 9 is resolved based on the voltage value V, the control means C cancels the energization prohibition to the electrodes 17 and 18 and activates the air sanitizer VW. Since it is in operation, air sterilization can be performed without any trouble after the water in the water storage tank 9 has been frozen. Furthermore, as described above, when the water in the water storage tank 9 is frozen, the ice in the water storage tank 9 can be quickly melted by energizing the heater 92 to heat the water storage tank 9. In addition, since the operation of the air sterilizer VW can be started at an early stage, the operation of the air sterilizer VW can be resumed quickly to generate electrolyzed water. In particular, in this embodiment, the control means C, which does not separately install special detection means, etc., judges the state of the water in the water storage tank 9 based on the voltage between the electrodes 17 and 18, and thereby sterilizes the air. Device VW And the operation of the heater 92 can be controlled.

 [0114] In the above, the control means C determines the state of the water in the water tank 9 based on the voltage between the electrodes 17 and 18. For example, the temperature of the water in the water tank 9 is directly detected. A possible temperature sensor 90 is provided (see Fig. 8). Based on the temperature of the water in the water storage tank 9 detected by the temperature sensor 90, the control means C operates the air sterilizer VW and the heater. It is possible to control the energization.

 Here, the operation in which the control means C controls the operation of the air sterilizer VW and the heater 92 according to the temperature of the water in the water storage tank 9 will be specifically described with reference to the flowchart shown in FIG. In this embodiment, the temperature of the water in the water tank 9 is based on the temperature TS at which the water in the water tank 9 freezes (for example, -5 ° C). It shall control the energization of ter 92. Specifically, the control means C of this embodiment controls the energization of the heater 92 and the operation of the air sterilizer VW (the energization of the electrodes 17 and 18) with a hysteresis width γ above and below the temperature TS. That is, when the temperature of the water in the water storage tank 9 falls below TS−y, the control means C energizes the heater 92 and prohibits the energization to the electrodes 17 and 18 (stops the air sanitizer VW). When the temperature rises above TS + y, the heater 92 is deenergized and the prohibition of energization of the electrodes 17 and 18 is canceled (the air sterilizer VW is activated).

 [0116] First, when the power of the air sterilizer VW is turned on (ON), or when the previous power passing time of the electrodes 17 and 18 has elapsed (for example, the above-mentioned 3 hours), the control means C Turn the switch on at S21, proceed to step S22, and reset flag 3 (FLAG3).

 [0117] Next, the control means C proceeds to step S23 and determines whether or not the flag 3 is reset. In this case, since flag 3 (FLAG3) has been reset in step S22 described above, control means C moves to step S24, detects the temperature T of water in the water storage tank 9, and this temperature T is It is determined whether the force is equal to or less than the TS-γ (ie, T≤TS-γ). At this time, if the temperature Τ is higher than the TS−γ (that is, the water in the water storage tank 9 is not frozen), the control means C moves to step S30 and stops the heater 92 ( Here, the state where the heater 92 is stopped is maintained), and the process proceeds to step S31.

[0118] Then, the control means C starts energization of the electrodes 17 and 18 in this step S31, and air Operate the sterilizer VW. The control means C operates the air sterilizer VW in step S31, returns to step S23 again, moves to step S24, and repeats the above-described operation.

 [0119] On the other hand, when the water in the water tank 9 freezes and the temperature T of the water in the water tank 9 detected by the temperature sensor 90 falls below TS-y, the control means C starts from step S24. Move to step S25, set flag 3 and then move to step S26. Then, the control means C operates the heater 92 in step 26. As a result, energization of the heater 92 is started and the water in the water storage tank 9 is heated. Next, the control means C moves to step S27, prohibits the energization of the electrodes 17 and 18, and stops the operation of the air sterilizer VW.

 [0120] After that, the control means C returns to step S23 and determines whether or not the flag 3 is reset. At this time, since the flag is set in step 25 as described above, the control means C moves to step S28, and whether or not the temperature T of the water in the water storage tank 9 is equal to or higher than TS + y. Judging. At this time, since the temperature T of the water in the water storage tank 9 is equal to or lower than TS−γ as described above, the control means C moves to step S26, maintains the state where the heater 92 is operated, and the air in step S27. While maintaining the disinfection device VW stopped state, return to step S23, move to step S28 and repeat the above-mentioned operation.

 [0121] Thereafter, when the energizing heater 92 melts the ice in the water storage tank 9 and the temperature 水 の of the water in the water storage tank 9 rises above TS + y, the control means C starts from step S28. After shifting to S29 and resetting flag 3, shift to step S30. Then, after stopping the heater 92 in step S30, the control means C moves to step S31, cancels the energization prohibition to the electrodes 17 and 18, and operates the air sterilizer VW.

[0122] Then, the control means C returns to step S23 and determines whether or not the flag 3 has been reset. At this time, since flag 3 has been reset in step 29 described above, control means C proceeds to step S24, and determines whether or not the temperature T of water in the water storage tank 9 is equal to or lower than TS−y. To do. Here, since the temperature T is equal to or higher than TS + y as described above, the control means moves to step S30, and after maintaining the state where the heater 92 is stopped, the process moves to step S31, where the air sanitizer VW Continue driving. Thereafter, the control means C returns to step S23 and repeats the above-described operation. [0123] As described above, even when the control means C controls the operation of the air sterilizer VW and the energization of the heater 92 based on the temperature of the water in the water storage tank 9 detected by the temperature sensor 90. The burden on the electrodes 17 and 18 can be eliminated. Similarly, when the freezing of the water in the water storage tank 9 is resolved, the prohibition of energization of the electrodes 17 and 18 is canceled and the air sanitizer VW is operated, so that the water in the water storage tank 9 is frozen. After elimination, air sterilization can be performed without any problem. Furthermore, energization of the heater 92 promotes thawing of water (ice) in the water storage tank 9, and the operation of the air sterilizer VW can be resumed quickly to generate electrolyzed water.

 Example 2

 [0124] In Example 1 described above, the control means C operates the heater 92 as the thawing means to suppress the freezing of water in the water storage tank 9 or promote the thawing of ice. Without providing any particular thawing means as in the above embodiment, for example, it is assumed that the water in the sterilized space is heated, that is, in this embodiment, the water tank 9 is heated by the air conditioner 100 of the passenger car 130. Also good. 13 and 14 are flow charts showing the operation of the control means C in this case. In this embodiment, the air sterilizer VW is attached to the air outlet 137 of the air conditioner 100 shown by P3 in FIG.

 FIG. 13 is a flowchart showing an operation in which the control means C controls the operation of the air sterilizer VW and the heater 92 based on the voltage values of the electrodes 17 and 18. The present embodiment is different from the first embodiment only in that the defrosting means is the air conditioner 100. That is, the control means C is based on the voltage value VB, and the heater 92 is replaced with the air conditioner 100. The only difference is in controlling the heating operation, which is almost the same as the operation shown in Fig. 11. In FIG. 13, steps denoted by the same reference numerals as those in FIG. 11 perform the same operation, and thus description thereof is omitted in this embodiment.

 Therefore, in this embodiment, only operations different from those in FIG. 11 will be described. First, electrode 17,

When the voltage between 18 is lower than VB +, the control means C proceeds from step S4 to step S19, maintains the state where the heating operation request is stopped, and proceeds to step S10. Thereby, the heating operation request from the air sterilizer VW is stopped in the air conditioner 100. At this time, the control means C performs the heating operation from the air sterilizer VW as described above. Even when the request is stopped, based on the detection of the temperature in the passenger compartment detected by the temperature sensor 101, the temperature is lower than a preset temperature, or the passenger switches on the heating operation. When operated, heating operation shall be performed.

 [0127] On the other hand, when the voltage force between the electrodes 17 and 18 increases to more than a, the control means C moves from step S4 to step S5 as in the above embodiment, and after setting the flag 1, step 1 8 Migrate to Then, control means C requests heating operation of the air conditioner 100 in step S18. That is, the control means C requests the air conditioner 100 to perform the heating operation, and starts the heating operation. In this case, the heating operation of the air conditioner 100 is performed regardless of the detection of the temperature sensor 101 and the switch operation by the passenger. By the heating operation, air heated in the water storage tank 9 is blown. Thereafter, the control means C proceeds to step S10 and repeats the operation described in FIG. 11 of the first embodiment.

 As described above, also in this embodiment, when the control means C determines that the water in the water storage tank 9 has dropped below a predetermined low temperature before freezing based on the voltage value, the air conditioner Since the water in the water storage tank 9 can be heated by operating the heater 100 and heating, the freezing of the water in the water storage tank 9 can be avoided as much as possible as in the first embodiment. . Furthermore, when the water in the water storage tank 9 is frozen, the ice in the water storage tank 9 can be melted quickly by heating the inside of the water storage tank 9 by heating operation of the air conditioner 100. Since the operation of the sterilization device VW can be started early, the operation of the air sterilization device VW can be resumed quickly to generate electrolyzed water.

 On the other hand, FIG. 14 is a flowchart showing an operation in which the control means C controls the operation of the air sterilizer VW and the heater 92 based on the temperature of the water in the water storage tank 9 detected by the temperature sensor 90. . This case is also almost the same as the operation shown in FIG. In FIG. 14, steps denoted by the same reference numerals as those in FIG. 12 perform the same operation, and thus description thereof is omitted in this embodiment.

[0130] That is, when the temperature T of the water in the water storage tank 9 is higher than the TS-γ, the control means C proceeds from step S24 to step S36 and maintains the state where the operation request for heating is stopped. Then, the process proceeds to step S31. Thereby, the heating operation request from the air sterilizer VW is stopped in the air conditioner 100. At this time, the control means C removes air as described above. Even if the heating operation request from the fungus device VW is stopped, the temperature is lower than a preset temperature based on the detection of the temperature in the passenger compartment detected by the temperature sensor 101. Heating operation by the passenger When the switch is operated, heating operation shall be performed.

 [0131] On the other hand, when the temperature T of the water in the water storage tank 9 falls below TS-γ, the control means C moves from step S24 to step S25 and sets flag 3 as in the previous embodiment. Move to step S35. Then, control means C requests heating operation of the air conditioner 100 in step S35. That is, the control means C makes a heating operation request to the air conditioner 100 and starts the heating operation. By the heating operation, air heated in the water storage tank 9 is blown. Thereafter, the control means C proceeds to step S27 and repeats the operation described in FIG. 12 of the first embodiment.

 [0132] As described above, when the control means C controls the operation of the air sterilizer VW and the heating operation of the air conditioner 100 based on the temperature of the water in the water storage tank 9 detected by the temperature sensor 90. In the same way as above, the water in the water storage tank 9 is avoided from freezing as much as possible, and when the water in the water storage tank 9 is frozen, the water storage tank 9 is heated by heating the air conditioner 100. It becomes possible to melt the ice in the water storage tank 9 at an early stage.

 In each of the above embodiments, the air sterilizer VW and the heater 92 or the air conditioner 100 are controlled by the voltage value between the electrodes 17 and 18 or the temperature of the water in the water storage tank 9. However, the present invention is not limited to this, and the temperature of the passenger compartment detected by the temperature sensor 101 of the air conditioner 100 may be taken in and judged by the control means C, and if the heater 92 is energized, the heating operation of the air conditioner 100 may be controlled.

 Example 3

Next, another embodiment of the air disinfecting apparatus of the present invention will be described with reference to FIGS. 15 to 17. FIG. 15 is a schematic diagram illustrating the configuration of the air sterilization apparatus VW of this embodiment, and FIGS. 16 and 17 are longitudinal side views of the air sterilization apparatus VW of FIG. Since the air sterilization apparatus VW of the present embodiment has almost the same configuration as the air sterilization apparatus VW of the first embodiment, the description of the same configuration as that of the first embodiment will be omitted, and only a different configuration will be described. 15 to 17, the same reference numerals as those in FIGS. 1 to 9 are the same or similar. The effect or action is exhibited.

 As shown in FIGS. 16 and 17, the gas-liquid contact member 8 of the present embodiment is surrounded by a cover 105 that can be opened and closed. A fan 110 as a blowing means is installed on one side of the gas-liquid contact member 8 that is the air inflow side, that is, one side of the cover 105, and a plurality of suction ports 106 formed on one side of the force bar 105. The gas-liquid contact member 8 is ventilated through the air. Further, a plurality of air outlets 107 are formed on the other side surface (the surface on the air outflow side of the gas-liquid contact member 8) facing the suction port 106 formed on one side surface of the cover 105.

 Thus, the air that has flowed into the cover 105 from the suction port 106 by the air blown from the fan 110 passes through and around the gas-liquid contact member 8, and then is blown to the other side of the cover 105. It is configured to be discharged from the outlet 107 to the outside. That is, the gas-liquid contact member 8 is provided substantially vertically on the water storage tank 109 so that the air inflow side surface and the air outflow side surface of the gas-liquid contact member 8 are parallel to the suction port 106 and the air outlet 107, respectively. It is done.

 [0137] Further, the cover 105 of the present embodiment has a structure capable of being sealed so that the periphery of the gas-liquid contact member 8 can be opened and closed. Specifically, a shutter 108 is attached to each of the suction port 106 and the air outlet 107 of the cover 105, and the air inlet 106 and the air outlet 107 are closed by the shutter 108 so that they can be opened and closed. The structure around the contact member 8 can be opened and closed. The opening and closing of the shutter 108 is controlled by the control means C.

[0138] The water storage tank 109 has a sealed or semi-sealed structure in order to prevent water leakage in the same manner as the water storage tank 9 of the first embodiment. The water storage tank 109 of the present embodiment has a semi-sealed structure that is not a completely sealed structure because a water absorbing member 19 described later can be separated from the electrolyzed water in the water tank 109. In addition, the water storage tank 109 of the present embodiment is formed by a casing filled with a porous material having a force such as a sponge or a non-woven fabric or a water-absorbing polymer material such as a gel. . Porous materials and water-absorbing polymer materials are excellent in water retention. Therefore, by filling the water storage tank 109 with such a porous material or water-absorbing polymer material, electrolysis in the water storage tank 109 is possible. A communication hole 33 through which the water absorbing member 19 formed in the water storage tank 109 is inserted into the porous material or the water-absorbing polymer material. Such water leakage can be effectively prevented.

 [0139] In addition, a pressure valve 37 and a water supply port 118 are formed on the upper surface of the housing. This water supply port 118 is provided in the water storage tank 109, and when the water storage tank 109 becomes empty based on the output of the water level sensor 75 for detecting the water level of the electrolyzed water stored in the water storage tank 109. This is a port for supplying the water (tap water) into the water storage tank 109. The water supply port 118 of the embodiment is constituted by, for example, a pore communicating with the inside and outside of the water storage tank 109, and the tip (upper end) surface of the water supply port 118 is made of a hydrophobic material. It is assumed that the water supply port 118 is always closed with a cap so as to be freely opened and closed. As described above, the water supply port 118 is constituted by pores, and the tip surface of the water supply port 118 is constituted by a hydrophobic material, so that the electrolyzed water in the water storage tank 109 is supplied to the water supply port 118. It becomes difficult to leak from the outside. Incidentally, 33B is a sealing material provided in the water storage tank 109 around the communication hole 33, and slidably contacts the water absorbing member 19.

 [0140] The air sterilization apparatus VW of the embodiment includes a plurality of water absorbing members 19. The water absorbing members 19 can be switched between a state immersed in the electrolyzed water in the water storage tank 109 and a state separated from the electrolyzed water. Specifically, when sterilizing the sterilization space (in the air), the water absorbing member 19 has one end in contact with the gas-liquid contact member 8 and the other end as shown in FIG. The water tank 109 is immersed in the electrolyzed water. As a result, the electrolyzed water in the water storage tank 109 is absorbed by the capillarity at the other end (lower half) of the water absorbing member 19. The absorbed electrolyzed water also rises in the water absorbing member 19 due to capillary action, and is sucked up from the water storage tank 109. The sucked electrolyzed water penetrates and is supplied to the gas-liquid contact member 8 provided in contact with the upper part by capillary action.

 On the other hand, when sterilization is not performed in the sterilized space, the water absorbing member 19 is separated from the electrolysis hydraulic power in the water storage tank 109. As shown in FIG. 19, the water absorbing member 19 is provided so as to be movable in the axial direction (vertical direction), and the water absorbing member 19 is separated from the water storage tank 109 (upward). To move the electrolysis hydraulic power away.

[0142] In addition, as shown in FIG. 20, when the water absorption member 19 and the gas-liquid contact member 8 are both installed so as to be movable in the axial direction (vertical direction), and sterilization in the sterilized space is not performed. , Water absorption member 19 The gas-liquid contact member 8 may be moved away from the electrolyzed water by moving in the direction away from the water storage tank 109 (upward). In this case, as shown in FIG. 21, a panel member 125 is attached to the other end (lower end) of the gas-liquid contact member 8, and the water absorbing member 19 and the gas-liquid contact member 8 are easily moved by expansion and contraction of the panel member 125. Alternatively, it is also possible to adopt a structure in which the movement is automatically moved by the panel member 125 by preventing the movement and releasing the movement. In addition, as the driving power source of the air sterilization apparatus VW of the present embodiment, a primary battery such as a dry battery (shown as BAT in FIGS. 16 to 21), a rechargeable secondary battery, and the like can be used. The solar cell used can be applied. Further, the cigar socket of the passenger car 130 may be used to connect to the knottery.

 It should be noted that the operation of the air sterilization apparatus VW of this embodiment and the operation of detecting and thawing the water in the water storage tank 109 by the control means C are the same as those in each of the above embodiments, and the description thereof is omitted.

[0144] In the air sterilization apparatus VW of the present embodiment as described in detail above, the same effects as those of the respective embodiments can be obtained. In particular, the air sterilization apparatus VW according to the present embodiment does not perform sterilization while the water absorbing member 19 is immersed in the electrolyzed water in the water storage tank 109 as shown in FIG. 18 during the air sterilization operation. In this case, that is, when the sterilization operation is stopped, as shown in any of FIG. 19 to FIG.

 [0145] As described above, when sterilization is not performed, the water absorption member 19 is separated from the water storage tank 109, so that the water absorption of the electrolytic water in the water storage tank 109 by the water absorption member 19 is interrupted. It will be possible to suppress the natural evaporation of. In this embodiment, the periphery of the gas-liquid contact member 8 is surrounded by a cover 105, and a plurality of suction ports 106 and outlets 107 formed in the cover 105 are configured to be closed by shutters 108, respectively. When bacteria are not used, as shown in FIG. 17, each inlet 106 and outlet 107 are closed with a shutter 8 and the periphery of the gas-liquid contact member 8 is sealed, so that the electrolyzed water is sealed. It becomes possible to more effectively suppress consumption due to natural evaporation. In particular, when the air disinfection device VW is mounted on the vehicle as in this example, the indoor temperature rises to close to + 60 ° C in the summer, and this structure is more effective in preventing the spontaneous evaporation of electrolyzed water. It becomes.

[0146] On the other hand, in this embodiment, the force that the fan 110 is provided in the air sterilizer VW. A configuration without the 110 is also conceivable. In that case, air sterilizer VW should be installed in front of air outlet 100 of air conditioner 100 such as P3 in FIG. In this case, the gas-liquid contact member is formed by disposing the suction port 106 of the cover 105 of the air sterilizer VW on the air outlet 100 side of the air conditioner 100, that is, on the windward side, and the air outlet 107 on the leeward side. It becomes possible to execute sterilization by the air sterilizer VW by venting the air discharged from the air conditioner 100 to 8. In particular, the air disinfecting apparatus VW of the present invention does not diffuse hypochlorous acid mist into the vehicle interior unlike the conventional apparatus, and therefore, this is the case where the air disinfecting apparatus VW is provided in the vehicle interior as in this embodiment. It is safe, and the spread of odor (hypochlorous acid odor) is prevented.

 In this embodiment, electrolyzed water is supplied to the gas-liquid contact member 8 from the water storage tank 9 as a water storage section using a capillary phenomenon, and the air ventilated through the gas-liquid contact member 8 is electrolyzed. Although the air is sterilized by bringing water into contact with it, the control of electricity to the electrode by the control means C of the present invention, in particular, the invention according to any one of claims 11 to 16, It is not limited to the application to the air sanitizer VW having the structure described in the present embodiment. For example, mist generating means for making electrolyzed water generated by electrolysis into a mist form is provided, and the mist-like electrolyzed water generated by the mist generating means is diffused into the sterilization space, and the sterilization space is empty. Needless to say, the present invention is also applicable to a device for sterilizing qi. Even when the invention according to any one of claims 11 to 15 is applied to such an air sterilization apparatus, the same effects as those of the above embodiments can be obtained.
