  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a partial schematic configuration diagram of an automobile 2 provided with an in-vehicle air sterilization device 1 of an embodiment of the air sterilization device of the present invention, and FIG. 2 shows a partial schematic configuration diagram of the air sterilization device 1. . The automobile 2 of the embodiment is a general ordinary passenger car, but may be a large vehicle such as a bus, a vehicle such as a train, an airplane, or the like.

  The automobile 2 includes an air conditioner for adjusting temperature. This air conditioner includes an evaporator 4 disposed in a circulation path 3 configured to communicate with a vehicle interior space, and a condenser 31 and a compressor 32 that together with the evaporator 4 constitute a refrigerant circuit of a cooling device R. Etc.

  Here, the refrigerant circuit of the cooling device R will be described. In the cooling device R, a refrigerant circuit is configured by sequentially connecting the compressor 32, the condenser 31, the expansion valve 33 serving as a decompression unit, and the evaporator 4 in an annular manner. As described above, the evaporator 4 constituting the cooling device R is disposed in the circulation path 3, and the condenser 31, the compressor 32, and the like are disposed in a machine room that is not in direct communication with the vehicle interior space. ing. In a normal passenger car or the like, the machine room in which the compressor 32 and the like are arranged and the evaporator 4 are arranged in a separated position due to space. For example, in the case of a large vehicle such as a bus In addition, the machine room is disposed at a position close to the evaporator 4.

  An air circulation blower 5 is arranged on the air upstream side of the evaporator 4 arranged in the circulation path 3, that is, on the air inflow side of the evaporator 4. Further, on the air suction side of the blower 5, A sterilization apparatus 10 is installed as a sterilization means. On the other hand, in the machine room where the compressor 32 and the condenser 31 are disposed, for example, a condenser blower 34 is disposed on the air inflow side of the condenser 31. For this reason, by operating the condenser blower 34, outside air is introduced into the machine room, and after the condenser 31 and the compressor 32 in the machine room are air-cooled by the outside air, they are discharged to the outside again. Therefore, in the present embodiment, the air flow path that circulates in the machine room and the air that is subjected to the sterilization / dehumidification process flow through independent flow paths.

  The sterilization apparatus 10 is arranged in parallel with the evaporator 4, and is disposed so as to extend above the evaporator 4 and to be positioned above the water receiver 12. The gas-liquid contact member 11, the circulation pump 13, and the electrolytic cell 14 are provided.

  As shown in FIG. 1, the water receiving tray 12 is configured such that a high-order part 12A located below the evaporator 4 and a low-order part 12B located below the gas-liquid contact member 11 are continuously integrated. The high-order part 12A is inclined and formed so as to be slightly lower toward the low-order part 12B. And the drainage hole is formed in the lower surface of this low-order part 12B, The water distribution pipe 21 in which the water discharge valve 20 was interposed is connected to the said drainage hole.

  On the other hand, the gas-liquid contact member 11 is a highly water-retentive member used as a gas-liquid contact means, a filter member having a honeycomb structure, a wide gas contact area is ensured, and electrolytic water dripping is possible. It has a structure that prevents clogging. That is, as shown in FIG. 3, the gas-liquid contact member 11 is formed in a honeycomb shape as a whole by joining a corrugated material 11A and a flat material 11B. These materials 11A and 11B include materials that are less reactive with electrolyzed water, which will be described later, that is, materials that are less deteriorated by electrolyzed water, such as polyolefin resin-based, PET resin-based, vinyl chloride resin-based, fluororesin-based, or Materials such as ceramic resin are used. In FIG. 1, the gas-liquid contact member 11 is erected substantially vertically so as to be parallel to the blower 5. However, the gas-liquid contact member 11 may be inclined to be arranged in the circulation path 3. According to this arrangement, it is possible to increase the contact area with the air flowing through the circulation path 3 as compared with the case where the gas-liquid contact members 11 having the same dimensions are arranged vertically.

  A water supply pipe 16 having one end connected to a water supply tank 15 is connected to the water tray 12 disposed below the gas-liquid contact member 11, and the water supply pipe 16 is disposed in the water tray 12. A water supply valve 17 that is controlled to open and close based on the output of the water level sensor 18 is provided. The water supply tank 15 is a tank for supplying tap water containing chloride ions as water supply means, and is disposed at a position where water can be easily supplied from the outside of the vehicle. It is assumed that the water supply opening is provided at a position where the water supply opening can be operated from the outside of the vehicle while being installed in the vehicle 2.

  And the circulation pump 13 is arrange | positioned at the low-order part 12B of the water receiving tray 12, The electrolysis tank 14 is connected to this circulation pump 13, The electrolysis water supply pipe (electrolysis water dripping means) is connected to this electrolysis tank 14 19 is connected. The electrolyzed water supply pipe 19 is configured to include a large number of water spray holes (not shown) on the outer peripheral portion, and is inserted into a water spray box (not shown) formed at the upper edge of the gas-liquid contact member 11.

  In this embodiment, three pairs of electrodes (not shown) are disposed in the electrolytic cell 14, and when the electrodes are energized, the tap water flowing into the electrolytic cell 14 is electrolyzed (electrochemical treatment) and activated. Oxygen species are generated. Here, the reactive oxygen species are oxygen molecules having an oxidation activity higher than that of normal oxygen and related substances, and are so-called narrowly defined as superoxide anion, singlet oxygen, hydroxyl radical, or hydrogen peroxide. These active oxygens include so-called broadly active oxygens such as ozone and hypohalous acid. The electrolytic cell 14 is disposed in the vicinity of the gas-liquid contact member 11 and is configured so that the active oxygen species generated by electrolyzing tap water can be quickly supplied to the gas-liquid contact member 11.

The electrode is, for example, an electrode plate having a base made of Ti (titanium) and a coating layer made of Ir (iridium) or Pt (platinum). The current value applied to the electrodes 51 and 52 is 20 mA (current density). A predetermined free residual chlorine concentration (for example, 1 mg (milligram) / l (liter)) is generated as milliampere / cm ² (square centimeter).

When the tap water is energized by the above electrode,
4H ⁺ + 4e ⁻ + (4OH ⁻ ) → 2H ₂ + (4OH ⁻ )
And the anode electrode
2H ₂ O → 4H ⁺ + O ₂ + 4e ⁻
At the same time, the chloride ions contained in the water (pre-added to tap water)
2Cl ⁻ → Cl ₂ + 2e ⁻
In addition, this Cl ₂ reacts with water,
Cl ₂ + H ₂ O → HClO + HCl
It becomes.

  In this configuration, when the electrode is energized, HClO (hypochlorous acid) having high sterilizing power is generated, and the air in the circulation path 3 passes through the gas-liquid contact member 11 supplied with the hypochlorous acid. As a result, it is possible to prevent germs from growing on the gas-liquid contact member 11 and inactivate viruses floating in the air passing through the gas-liquid contact member 11. Further, when the odor passes through the gas-liquid contact member 11, it reacts with hypochlorous acid in the electrolytic water, and is ionized and dissolved to be removed from the air and deodorized.

  Next, the operation of the sterilization apparatus 10 will be described. The sterilization apparatus 10 can perform operation control by operating a control panel (not shown) provided in the vehicle. In this embodiment, when the operation start of the sterilization apparatus 10 is operated, The operation of the air conditioner shall be started at the same time. Note that the air conditioner is independently controlled when the sterilization apparatus 10 is not operated.

  When the operation of the sterilizer 10 is started, the circulation pump 13 is driven, and the tap water accumulated in the lower portion 12B of the water tray 12 is supplied to the electrolytic cell 14. In this electrolytic cell 14, by energizing the electrodes, tap water is electrolyzed to generate electrolytic water containing active oxygen species (electrochemical treatment). The electrolyzed water is sprinkled into the watering box through watering holes (not shown) of the electrolyzed water supply pipe 19, soaks into the upper edge of the gas-liquid contact member 11, and gradually gets wet toward the lower part. To do.

  The surplus electrolyzed water is stored in the lower portion 12B of the water tray 12. In the configuration of the embodiment, water is circulated, and when the amount of water is reduced by evaporation or the like, the water supply valve 17 is controlled to open and close based on the output of the water level sensor 18, so that tap water is stored in advance. An appropriate amount of tap water is supplied to the lower portion 12B of the water tray 12 via the tank 15, and a predetermined water level is maintained.

  In the embodiment, since electrolyzed water containing hypochlorous acid is stored in the lower portion 12B of the water tray 12, no germs are generated in the tray 12, and slime is prevented from being generated. Therefore, the frequency of cleaning and maintenance of the dish 12 is reduced, and labor such as maintenance can be reduced.

  In addition to this, after a certain period of time, for example, about 2 to 4 weeks, or the conductivity of water staying in the lower portion 12B of the water tray 12 becomes a predetermined value, for example, 2000 to 20000 μS / cm. At that time, the water discharge valve 20 may be opened to discharge the water in the water tray 12 to the outside. This prevents the water in the water tray 12 from being spoiled under conditions such as the sterilization apparatus 10 not being operated for a certain period of time, and avoiding the use of the spoiled water in the sterilization process during the next operation. Is possible. Therefore, the sterilization apparatus 10 can always perform sterilization processing of air using sanitary water.

  Then, the air flowing into the circulation path 3 from the inside of the vehicle is supplied to the gas-liquid contact member 11 wetted with the electrolyzed water by the blower 5. The air in the circulation path 3 comes into contact with the active oxygen species soaked in the gas-liquid contact member 11 and is blown out toward the evaporator 4 installed on the air downstream side of the gas-liquid contact member 11. After exchanging heat with 4, it is discharged into the vehicle. This reactive oxygen species has the function of destroying and eliminating (removing) the surface proteins (spikes) of the virus that are essential for the infection when, for example, an influenza virus enters the air in the car 2. Then, the influenza virus and a receptor (receptor) necessary for the virus to be infected do not bind, thereby preventing the infection. As a result of a verification test in collaboration with the Institute for Hygiene and Environment, it was found that 99% or more of the virus can be removed when the air in which the influenza virus has entered is passed through the gas-liquid contact member 11 of this configuration.

  On the other hand, when the operation of the sterilization apparatus 10 is started, the operation of the cooling device R is also started as described above. Therefore, when the operation of the compressor 32 is started, the high-temperature and high-pressure gas refrigerant discharged from the refrigerant pipe on the discharge side of the compressor 32 flows into the condenser 31. The refrigerant condensed and liquefied in the condenser 9 flows into the expansion valve 33 and is decompressed, and then flows into the evaporator 4. And the refrigerant | coolant which flowed in in the evaporator 4 takes heat from the circumference | surroundings, and exhibits a cooling effect | action. The refrigerant discharged from the evaporator 4 returns to the compressor 32.

  Therefore, after the air contacted with the electrolyzed water in the gas-liquid contact member 11 of the sterilization apparatus 10 is humidified by the electrolyzed water, the air is cooled by the evaporator 4 installed on the air downstream side of the gas-liquid contact member 11, It is condensed and dehumidified on the surface of the evaporator 4. Then, the condensed water condensed on the surface of the evaporator 4 is dropped from the lower end of the evaporator 4 into the water tray 12 installed below. The condensed water received in the high level portion 12A of the water tray 12 flows down toward the low level portion 12B along the inclination of the high level portion 12A, and is stored together with excess electrolyzed water received in the gas-liquid contact member 11. The

  Therefore, the condensed water condensed in the evaporator 4 and dripped onto the high level part 12A of the water tray 12 can be reused as electrolytic water by being stored together with the electrolytic water in the low level part 12B. This makes it possible to reduce the number of times that the water level in the lower part 12B decreases to a predetermined water level or less, and to reduce the number of times of water supply from the water supply tank 15 per unit time. Therefore, it is possible to extend the interval of water supply from the outside to the water supply tank 15, and the convenience is improved.

  As described above, the sterilization apparatus 10 through which the air in the vehicle is ventilated is provided, and the sterilization apparatus 10 holds the electrolyzed water so that the cold air ventilated through the sterilization apparatus 10 and the electrolyzed water are brought into contact with each other. The contact with the electrolyzed water makes it possible to sterilize the air in the vehicle, and the sterilization in the vehicle can be performed efficiently. In this case, since the mist-like electrolyzed water is not diffused into the vehicle, the air that has passed through the sterilizing apparatus 10 is once humidified by contact with the electrolyzed water, and then by the evaporator 4 that functions as a dehumidifying means. Since it is dehumidified, it is possible to avoid the disadvantage that the air to be sterilized is humidified more than necessary even when the air in the vehicle, which is a relatively small space, is sterilized.

  As a result, the humidity inside the vehicle rises, and the inconvenience that visibility is deteriorated can be avoided by fogging the small space, in this embodiment, the window glass 22 constituting the vehicle. Therefore, in driving, visibility is improved and safety can be ensured. In addition, in a small space with a limited volume inside the vehicle, it is possible to avoid the inconvenience that the humidity increases abnormally, and it is possible to achieve air purification while suppressing an increase in the discomfort index.

  Furthermore, since it is possible to prevent or suppress inconvenience due to the occurrence of dew condensation, it is possible to avoid inconveniences that cause equipment failure by causing dew condensation to occur in the equipment installed in the vehicle. It becomes.

  In addition, the sterilization apparatus 10 includes a gas-liquid contact member 11 that is formed of a material that is less reactive with the electrolyzed water, holds the electrolyzed water, and allows air to flow. The durability is improved and the life can be extended. Further, since the sterilization apparatus 10 is provided with an electrolyzed water supply pipe 19 for dropping electrolyzed water generated in the electrolytic cell 14 to the gas-liquid contact member 11, the electrolyzed water is evenly distributed over the entire area of the gas-liquid contact member 11. It is possible to sterilize the cold air that has passed through it uniformly. In particular, in the embodiment, in order to ventilate the air in the circulation path 3 to the gas-liquid contact member 11, it is possible to use a blower 5 for circulating cold air that is used to exchange heat with the evaporator 4 as an air conditioner. Therefore, it is possible to ventilate the gas-liquid contact member 11 without providing a special blower for ventilation, and it is possible to reduce the number of parts and the cost.

  Note that the surfaces of the evaporator 4 and the blower 5 disposed on the air downstream side of the sterilization apparatus 10 are coated with a material having a predetermined resistance to, for example, an anticorrosive agent or a chlorine-based substance. As a result, the corrosion resistance of the evaporator 4 and the blower 5 itself can be improved, and the sterilization apparatus 10 can provide electrolyzed water containing a substance (active oxygen species) having strong oxidizing power such as ozone and hypochlorous acid. Therefore, it is possible to avoid the disadvantage that the surfaces of the evaporator 4 and the blower 5 are corroded by the humidified air.

  Further, by using a hydrophilic material as a material for coating the surface of the evaporator 4, the corrosion resistance of the evaporator 4 itself can be improved, and moisture in the air can be increased by the hydrophilic material. It becomes easy to adsorb | suck, it becomes possible to cool the said water | moisture content more effectively, and it becomes easy to condense. Therefore, the air humidified by the sterilization apparatus 10 can be effectively dehumidified.

  In addition, the coating process to the surface of the evaporator 4 is a film formation by the material which has both the property as a material which has predetermined | prescribed tolerance with respect to an anticorrosive agent and a chlorine-type substance as mentioned above, and the property as a hydrophilic material, Alternatively, in the case where a film is formed by mixing these materials, or in the case where these are formed into a layer, the high corrosion resistance of the evaporator 4 itself can be realized and high dehumidification can be achieved as described above. It is possible to exert an effect.

  In the first embodiment, the water tray 12 is configured such that the high-order part 12A located below the evaporator 4 and the low-order part 12B located below the gas-liquid contact member 11 are integrally formed. For example, as shown in FIG. 4, a partition wall 12 </ b> C is provided between a high-order part 12 </ b> A located below the evaporator 4 and a low-order part 12 </ b> B located below the gas-liquid contact member 11. The dew condensation water dripped from the evaporator 4 may be configured not to flow into the lower portion 12B for storing the electrolyzed water. In such a case, a drainage hole is provided in the lower surface of the high level part 12A located below the evaporator 4, and the dew condensation water stored in the high level part 12A is connected to the outside via a water pipe 24 connected to the drainage hole. Discard. At this time, the water distribution pipe 24 may be configured to merge on the downstream side of the water distribution pipe 21 and the water discharge valve 20 connected to the drain hole of the lower portion 12B. Moreover, in FIG. 3, although the high-order part 12A and the low-order part 12B of the water receiving tray 12 are integrally formed via the partition wall 12C, they may be configured separately.

  Moreover, in the said Example 1, the air blower 5 which performs ventilation control in the circulation path 3 is the air inflow side of the evaporator 4, Comprising: On the air downstream side of the sterilization apparatus 10, ie, the gas-liquid contact member 11, Although installed, the arrangement position is not limited to this. For example, it may be on the air outflow side of the evaporator 4 as shown in FIG. 5, and is located on the air upstream side of the gas-liquid contact member 11 and adjacent to the gas-liquid contact member 11 as shown in FIG. As shown in FIG. 7, the gas-liquid contact member 11 may be on the air upstream side of the circulation path 3 with a predetermined interval.

  In any case, the air sucked into the circulation path 3 from the inside of the vehicle by the operation of the blower 5 passes through the gas-liquid contact member 11 of the sterilization apparatus 10 and then passes through the evaporator 4 to be removed. After the bacteria and dehumidification treatment, the vehicle is returned to the vehicle.

  Further, in the first embodiment, tap water (electrolyzed water) stored in the lower portion 12B of the water tray 12 is sucked into the electrolytic cell 14 by the circulation pump 13 and electrolyzed in the electrolytic cell 14 to be reactive oxygen species. Is generated, the electrolyzed water is supplied from the electrolyzed water supply pipe 19 to the gas-liquid contact member 11. However, the method of supplying electrolyzed water to the gas-liquid contact member 11 is not limited to this.

  For example, as shown in FIG. 8, the water absorbing member 27 may be provided in contact with the gas-liquid contact member 11 installed above the lower portion 12B of the water tray 12. The water absorbing member 27 is formed in a vertically long column shape by a material having excellent water absorption such as sponge or non-woven fabric, and one end portion of the water absorbing member 27 is provided in contact with the gas-liquid contact member 11 and others. The end is provided so as to be immersed in the electrolyzed water in the lower portion 12B of the water tray 12. In this case, the lower portion 12B of the water tray 12 is provided with the electrodes as described above, and by energizing the electrodes, the tap water stored in the lower portion 12B of the water tray 12 is electrolyzed. Thus, the electrolyzed water in which active oxygen species are generated is obtained.

  The water absorbing member 27 of the present embodiment can be switched between a state immersed in the electrolyzed water in the water tray 12 and a state separated from the electrolyzed water, and when the operation of the sterilizer 10 is started. The water absorbing member 27 is in a state in which one end is in contact with the gas-liquid contact member 11 and the other end is immersed in the electrolyzed water in the water tray 12. Thereby, the electrolyzed water in the water receiving tray 12 is sucked up from the other end, and the electrolyzed water sucked up by the water absorbing member 27 is supplied to the gas-liquid contact member 11 provided above by capillary action.

  Then, the air flowing into the circulation path 3 from the inside of the vehicle is supplied to the gas-liquid contact member 11 wetted with the electrolyzed water by the blower 5. The air in the circulation path 3 comes into contact with the active oxygen species soaked in the gas-liquid contact member 11 and is blown out toward the evaporator 4 installed on the air downstream side of the gas-liquid contact member 11. After exchanging heat with 4, it is discharged into the vehicle.

  Also in this manner, as in the first embodiment, the air contacted with the electrolyzed water in the gas-liquid contact member 11 of the sterilizing apparatus 10 can be sterilized, and the air humidified by the electrolyzed water is It cools by the evaporator 4 installed in the air downstream side of the liquid contact member 11, is condensed on the surface of the evaporator 4, and is dehumidified. Therefore, the sterilization process can be performed without humidifying the air to be sterilized more than necessary.

  In FIG. 8, similarly to the first embodiment, the water receiving tray 12 includes a high-order part 12 </ b> A located below the evaporator 4 and a low-order part 12 </ b> B located below the gas-liquid contact member 11. However, the present invention is not limited to this, and similarly to FIG. 4, as shown in FIG. 9, the high position portion 12 </ b> A positioned below the evaporator 4 and the low position positioned below the gas-liquid contact member 11. It is good also as a structure which provides the partition wall 12C between the part 12B, and the dew condensation water dripped from the evaporator 4 does not flow in into the low-order part 12B which stores electrolyzed water.

  Next, an in-vehicle air sterilization apparatus 30 as Example 2 of the air sterilization apparatus of the present invention will be described with reference to FIG. FIG. 10 shows a schematic configuration diagram of the air sterilizer 30. In the figure, the same reference numerals as those in FIG. 1 denote the same effects. The air sanitizer 30 is also used in large vehicles such as passenger cars and buses, vehicles such as trains, aircraft, etc., as in the first embodiment.

  The automobile is provided with an air conditioner for adjusting the temperature. The air conditioner is provided with an evaporator 4 disposed in a circulation path 3 configured to communicate with the interior space of the vehicle, and the evaporator. It is comprised from the condenser 31 and the compressor 32 which comprise the refrigerant circuit of the cooling device R with the cooler 4 grade | etc.,. As described above, the evaporator 4 constituting the cooling device R is disposed in the circulation path 3, and the condenser 31 and the compressor 32 are disposed in the machine chamber 29.

  Here, the machine room 29 in which the compressor 32 and the like in the present embodiment are arranged constitutes the circulation path 3 and a series of air circulation paths. That is, the air discharge side of the machine room 29 is formed in communication with the circulation path 3 located on the air suction side of the sterilization apparatus 10. Further, a blower 36 is disposed on the air inflow side of the condenser 31 of the machine room 29. In addition, since the structure of the sterilization apparatus 10 is the same structure as the said Example, description is abbreviate | omitted.

  With this configuration, when the operation of the sterilization apparatus 10 is started, the operation of the air conditioner is also started at the same time. In this embodiment as well, the air conditioner is independently controlled when the sterilization apparatus 10 is not operated.

  When the operation of the sterilization apparatus 10 is started, the electrolyzed water is infiltrated into the gas-liquid contact member 11 as in the above embodiment. When the cooling device R and the blower 36 are operated, the air in the vehicle is sucked into the machine room 29 and is warmed by the condenser 31 and the compressor 32. The heated air flows into the circulation path 3 from the machine room 29, contacts the active oxygen species that has soaked into the gas-liquid contact member 11, and is evaporated on the air downstream side of the gas-liquid contact member 11. It blows out toward the container 4 and is discharged into the vehicle after exchanging heat with the evaporator 4.

  Since the evaporator 4 exhibits the cooling action as in the first embodiment, the air in contact with the electrolyzed water in the gas-liquid contact member 11 of the sterilization apparatus 10 is humidified by the electrolyzed water, It cools by the evaporator 4 installed in the air downstream of the gas-liquid contact member 11, is condensed on the surface of the evaporator 4, and is dehumidified. Then, the condensed water condensed on the surface of the evaporator 4 is dropped from the lower end of the evaporator 4 into the water tray 12 installed below. The condensed water received in the high level portion 12A of the water tray 12 flows down toward the low level portion 12B along the inclination of the high level portion 12A, and is stored together with excess electrolyzed water received in the gas-liquid contact member 11. Reused as electrolyzed water.

  In this way, after the air in the vehicle is once heated by the condenser 31 and the compressor 32 constituting the cooling device R, the air is brought into contact with the electrolyzed water by being ventilated through the sterilizing device 10 holding the electrolyzed water. And the air in the car is sterilized. The air that has passed through the sterilizing apparatus 10 is once humidified by contacting with the electrolyzed water, and then dehumidified by the evaporator 4 that functions as a dehumidifying means, so the air in the vehicle, which is a relatively small space, is removed. Even when the bacteria treatment is performed, it is possible to avoid the disadvantage that the air to be sterilized is humidified more than necessary.

  In this case, the air in the vehicle is once heated by the condenser 31, etc., then sterilized, and further dehumidified by being cooled. Therefore, the air temperature after processing when discharged into the vehicle It is possible to reduce the fluctuations of. As a result, the dehumidification can avoid the inconvenience that the in-vehicle temperature is remarkably lowered, and a comfortable in-vehicle space can be configured.

  In this embodiment as well, it is possible to avoid inconvenience that visibility deteriorates by increasing the humidity in the vehicle and fogging the small space, in this embodiment, the window glass 22 constituting the vehicle. Become. Therefore, in driving, visibility is improved and safety can be ensured. In addition, in a small space with a limited volume inside the vehicle, it is possible to avoid the inconvenience that the humidity increases abnormally, and it is possible to achieve air purification while suppressing an increase in the discomfort index.

  Furthermore, since it is possible to prevent or suppress inconvenience due to the occurrence of dew condensation, it is possible to avoid inconveniences that cause equipment failure by causing dew condensation to occur in the equipment installed in the vehicle. It becomes.

  Moreover, in the said Example 2, the air discharge side located in the compressor 32 side of the machine room 29 and the circulation path 3 located in the air inflow side of the sterilization apparatus 10 communicate, and comprise a series of air circulation paths. And although it has set as the structure which returns in the vehicle after heating, disinfection, and dehumidifying the air in the vehicle in which the condenser 31 side of the machine room 29 was suck | inhaled, it is not limited to this. For example, as shown in FIG. 11, the circulation path 3 located on the air discharge side of the evaporator 4 and the air inflow side provided with the condenser blower 36 of the machine room 29 communicate with each other to form a series of air circulation paths. You may do it. In this case, the air in the vehicle flows into the circulation path 3 from the air inflow side of the sterilization apparatus 10 by the operation of the blower 36, is sterilized, cooled and dehumidified in the evaporator 4, and then the machine room 29 flows into the vehicle 29 and is heated by the condenser 31 and the compressor 32, and then returned to the vehicle.

  Moreover, the surface of the evaporator 4 and the air blower 36 disposed on the air downstream side of the sterilization apparatus 10 is made of a material having a predetermined resistance to, for example, an anticorrosive or a chlorine-based substance, as in the first embodiment. A coating treatment is applied. As a result, the corrosion resistance of the evaporator 4 and the blower 36 itself can be improved. In the sterilization apparatus 10, the electrolyzed water containing a substance (active oxygen species) having strong oxidizing power such as ozone and hypochlorous acid can be used. Thus, it is possible to avoid the disadvantage that the surfaces of the evaporator 4 and the blower 36 are corroded by the humidified air.

  Further, by using a hydrophilic material as a material for coating the surface of the evaporator 4, the corrosion resistance of the evaporator 4 itself can be improved, and moisture in the air can be increased by the hydrophilic material. It becomes easy to adsorb | suck, it becomes possible to cool the said water | moisture content more effectively, and it becomes easy to condense. Therefore, the air humidified by the sterilization apparatus 10 can be effectively dehumidified.

  Also in this case, the coating treatment on the surface of the evaporator 4 has both the property as a material having a predetermined resistance to the anticorrosive and the chlorine-based material as described above and the property as a hydrophilic material. In the case where a film is formed by a material, a film is formed by mixing these materials, or a film is formed in a layered manner, the high corrosion resistance of the evaporator 4 itself can be realized as described above. As well as being able to exhibit a high dehumidifying effect.

  Further, in this case, the arrangement position of the blower 36 is not limited to the air inflow side of the condenser 31; for example, as shown in FIG. 13 may be the air outflow side of the evaporator 4 and the air outflow side of the machine room 29 located on the compressor 32 side as shown in FIG.

  In any case, the air sucked into the circulation path 3 from the inside of the vehicle by the operation of the blower 36 passes through the gas-liquid contact member 11 of the sterilization apparatus 10 and then passes through the evaporator 4 to be removed. After being treated with bacteria and dehumidification, it is heated by the waste heat of the condenser 31 and the compressor 32 in the machine room 29 and then returned to the vehicle.

  Also in this way, the air in the vehicle is sterilized, further dehumidified by being cooled, heated up by the condenser 31 and the like, and then discharged into the vehicle. It is possible to reduce the fluctuations of. By performing dehumidification, it becomes possible to avoid the inconvenience that the in-vehicle temperature is remarkably lowered, and it is possible to configure a comfortable in-vehicle space.

  Next, with reference to FIG. 15 thru | or FIG. 18, the Example which employ | adopted the air sanitizer 1 of this invention for the air conditioner used for indoor air conditioning is demonstrated. 15 is a schematic configuration diagram of the sterilization apparatus 41, FIG. 16 is a schematic configuration diagram of the sterilization apparatus 42, FIG. 17 is a schematic cross-sectional view of the indoor unit 40 of the air conditioner including the sterilization apparatus 41, and FIG. The schematic sectional drawing of the indoor unit 40 of the air conditioner provided with the microbe apparatus 41 is shown.

  The sterilization apparatus 41 in the present embodiment is an apparatus having substantially the same configuration as that of the first embodiment, and the water supply tank 43 is disposed in the housing 46 constituting the indoor unit 40. Is directly connected to the water tray 12. Incidentally, 44 and 45 shown in the drawing are electrodes arranged in the electrolytic cell 14 as described above. FIG. 16 shows a sterilization apparatus 42 as another embodiment of the sterilization apparatus 41, and the water supply tank 43 is directly connected to the water receiving tray 12 in the same manner as the sterilization apparatus 41. In the sterilization apparatus 42, the electrolytic cell 14 is not provided, the electrodes 44 and 45 are directly provided in the water tray 12, and at least a part of the electrodes 44 and 45 is received in the water tray 12. Soaked in electrolyzed water.

  The sterilization apparatus 41 is disposed in the casing 46 constituting the indoor unit 40 so as to face the air suction port 47, and the sterilization apparatus 41 has an outdoor unit (not shown) on the air outflow side. The use side heat exchanger 48 which comprises a refrigerant circuit with the compressor and heat exchanger which are provided in a machine is arrange | positioned. In addition, a blower 49 is disposed on the air outflow side of the use side heat exchanger 48, and the casing 46 located on the air discharge side of the blower 49 and below the air suction port 47 includes: An air discharge port 50 is formed.

  With this configuration, when the operation of the air conditioner is started, the air sucked into the housing 46 by the blower 49 through the air suction port 47 is electrolyzed water in the sterilization apparatus 41 as in the first embodiment. After being sterilized by coming into contact with it, it passes through the use side heat exchanger 48. At this time, moisture in the air humidified by contacting with the electrolyzed water is condensed and dehumidified on the surface of the use side heat exchanger 48, and then sterilized indoors from the air outlet 50. It becomes possible to discharge air.

  Thereby, since it becomes possible to dehumidify the air humidified by contacting the electrolyzed water in the sterilization apparatus 41 using the use side heat exchanger 48, the indoor air is appropriately sterilized. However, it is possible to avoid the disadvantage that the air humidified more than necessary is discharged into the room. In such a case, it becomes possible to dehumidify the air after sterilization using the use side heat exchanger 48 that is indispensable for the indoor unit 40 of the air conditioner. A comfortable humidity space can be provided, and the production cost can be reduced.

  In this embodiment as well, the surfaces of the use side heat exchanger 48 and the blower 49 disposed on the air downstream side of the sterilization apparatus 41 are made of a material having a predetermined resistance against, for example, an anticorrosive or a chlorine-based substance. Coating treatment. Thereby, the corrosion resistance of the use side heat exchanger 48 and the blower 49 itself can be improved, and the sterilization apparatus 41 includes a substance (active oxygen species) having strong oxidizing power such as ozone and hypochlorous acid. It is possible to avoid the disadvantage that the surfaces of the use-side heat exchanger 48 and the blower 49 are corroded by the air humidified with the electrolyzed water.

  Further, by using a hydrophilic material as a material for coating the surface of the use side heat exchanger 48, the corrosion resistance of the use side heat exchanger 48 itself can be improved, and the use side heat exchange can be improved. Moisture in the air is easily adsorbed on the surface of the vessel 48, and the moisture can be cooled more effectively and is easily condensed. Therefore, the air humidified by the sterilization apparatus 41 can be effectively dehumidified.

  The coating treatment on the surface of the use-side heat exchanger 48 is performed by a material having both a property as a material having a predetermined resistance to the anticorrosive and the chlorine-based material as described above and a property as a hydrophilic material. In the case of film formation, film formation by a mixture of these materials, or when these are formed into layers, the high heat resistance of the use side heat exchanger 48 itself is realized in the same manner as described above. And a high dehumidifying effect can be exhibited.

  In addition, as shown in FIG. 17, in the indoor unit 40 in this embodiment, a drain receiver 51 is disposed below the use side heat exchanger 48, and the sterilization is adjacent to the drain receiver 51. A water tray 12 constituting the device 41 is disposed. At this time, the drain receiver 51 is positioned lower than the water tray 12 and is configured to be able to receive the electrolyzed water overflowing from the water tray 12 with the drain tray 51. A drain hose 52 is connected to the drain receiver 51, and drain water in the drain receiver 51 can be discharged to the outside.

  Therefore, even when the electrolyzed water used in the sterilization apparatus 41 overflows the water tray 12, it can be appropriately discharged to the outside through the drain receiver 51, and the surroundings of the indoor unit 40 can be obtained. It is possible to avoid inconveniences such as getting wet.

  FIG. 18 shows an indoor unit 40 as another embodiment. The water tray 53 of the sterilization apparatus 41 disposed in the indoor unit 40 is formed to extend below the use side heat exchanger 48 and further to the back of the use side heat exchanger 48. As shown in FIG. 18, the water receiving tray 53 is formed with a high portion 53 </ b> C formed so as to be high below the use side heat exchanger 48, and is located in front of the high portion 53 </ b> C, and is in gas-liquid contact. A first low-order part 53A located below the member 11 and a second low-order part 53B located rearward are formed. At this time, the second low-order part 53B is formed lower than the first low-order part 53A, and a drain hose 54 for discharging drain water to the outside is connected.

  With this configuration, the condensed water condensed in the use side heat exchanger 48 is received by the high level portion 53C of the water receiving tray 53, and then the first low level portion 53A or the drain hose positioned below the gas-liquid contact member 11. It is possible to flow down to the second lower part 53B to which 54 is connected. Therefore, when the first lower portion 53A in which the electrolyzed water is stored does not reach full water, the condensed water can be reused as electrolyzed water, and the water supply interval to the water supply tank 43 can be extended. it can. Thereby, it becomes possible to simplify water supply work.

  On the other hand, when the first low-order part 53A reaches full water, the dew condensation water discharged from the use side heat exchanger 48 and the electrolyzed water overflowing from the first low-order part 53A are the second low-order part 53B. It is possible to flow into the inside and appropriately discharge to the outside through the drain hose 54. This makes it possible to avoid inconveniences such as getting wet around the indoor unit 40.

  Next, with reference to FIG. 19, the air sanitizer 60 as another Example is explained in full detail. The air sterilization apparatus 60 in the present embodiment is provided in large vehicles such as automobiles and buses, vehicles such as trains, airplanes, and the like, as in the first embodiment.

  The air sterilization apparatus 60 in this embodiment includes a sterilization apparatus 10 as described in detail in the first embodiment, a desiccant air conditioner 61 as a dehumidifying means, and a heat exchanger 62 arranged in a main body 64. It is a device made up of. The desiccant air conditioner 61 includes a rotary dehumidifier 66 having a moisture adsorbing element 65, a blower 63 that sucks air in the vehicle, a regeneration fan 68, a regeneration heater (electric heater) 67, and the like. The blower 63 is disposed on the air outflow side of the sterilization apparatus 10, and after passing the air after sterilization processing by the sterilization apparatus 10 through a moisture adsorption region (described later) of the moisture adsorption element 65, Discharge into the car. In addition, since the sterilization apparatus 10 has the same configuration as that of the first embodiment, detailed description thereof is omitted.

  The regeneration fan 68 is operated and sucks the air in the heat exchanger 62 through the regeneration air intake unit 70 and sequentially passes through the regeneration heater 67 and a moisture release region (described later) of the moisture adsorption element 65. The regeneration air discharge unit 71 returns the heat to the heat exchanger 62 again.

  On the other hand, the moisture adsorbing element 65 has a disk shape with a predetermined thickness and an air passage around it, and is driven by an electric motor (not shown) to rotate about half a minute, for example. The moisture adsorption element 65 is configured to adsorb moisture contained in the air when air passes through it. The air heated by the regenerative heater 67 passes through the moisture adsorption element 65 so that the moisture adsorbed on the moisture adsorption element 65 is absorbed by the heated air.

  Although the moisture adsorption element 65 rotated by the electric motor is not shown, an air passage provided in the periphery is partitioned by a region partition plate to constitute a first air passage and a second air passage. The portion of the moisture adsorption element 65 located in the first air passage is defined as the moisture adsorption region, and the portion of the moisture adsorption element 65 located in the second air passage is defined as the moisture release region.

  When attention is paid to a part of the moisture adsorption element 65, a cycle in which the part shifts from the moisture adsorption region to the moisture release region and returns to the moisture adsorption region by being rotated by the electric motor is repeated. The air (regeneration air) in the heat exchanger 62 sucked from the regeneration air intake unit 70 by the regeneration fan 68 is heated by the regeneration heater 67 and then the moisture is released from the moisture adsorption element 65 from the second air passage. After passing through the region, the regeneration air exhaust unit 71 is configured to exhaust the heat to the heat exchanger 62.

  The heat exchanger 62 includes air before flowing into the gas-liquid contact member 11 of the sterilization apparatus 10 provided side by side and air heated by the regenerative heater 67 of the desiccant air conditioner 61 and containing a lot of moisture. A heat exchanger for exchanging heat, and a condensed water drain pipe 62 </ b> A for discharging condensed water is connected to a lower end portion of the heat exchanger 62. The condensed water drain pipe 62 </ b> A is opened facing the water tray 12 that constitutes the sterilization apparatus 10.

  With this configuration, when the operation of the air sterilizer 60 is started, the desiccant air conditioner 61 is operated along with the start of the operation of the sterilizer 10. Thus, the air in the vehicle sucked into the main body 64 is heated by the heat exchanger 62 through which the air heated by the regeneration heater 67 flows, and then electrolyzed in the gas-liquid contact member 11 of the sterilization apparatus 10. Contact with water. The air sterilized and humidified by the electrolyzed water is discharged by the blower 63 into the vehicle through the first air passage and the moisture adsorption area of the moisture adsorption element 65.

  In this embodiment as well, the surface of the blower 63 disposed on the air downstream side of the sterilization apparatus 10 is coated with a material having a predetermined resistance to, for example, an anticorrosive or a chlorine-based substance. Yes. As a result, the corrosion resistance of the blower 63 itself can be improved, and the sterilization apparatus 10 is humidified with electrolyzed water containing a substance (active oxygen species) having strong oxidizing power such as ozone and hypochlorous acid. It is possible to avoid the disadvantage that the surface of the blower 63 is corroded by the air.

  At this time, the moisture contained in the air is adsorbed by the moisture adsorbing element 65 in the portion serving as the moisture adsorption region, and is transported to the moisture release region by rotation by the electric motor. Then, air in the heat exchanger 62 (regeneration air) is sucked from the regeneration air intake unit 70 by the operation of the regeneration fan 68. The sucked air is heated to about + 140 ° C. by the regenerative heater 67, passes through the moisture release region of the moisture adsorption element 65, and is discharged from the regeneration air discharge unit 71 to the heat exchanger 62. At this time, the air in the heat exchanger 62 receives the moisture adsorbed by the moisture adsorbing element 65 in the moisture adsorbing area in the moisture releasing area of the moisture adsorbing element 65 and then enters the main body 64 by the blower 63 from the inside of the vehicle. The water cooled and condensed by the sucked air is received in the water receiving tray 12 constituting the sterilization apparatus 10 through the condensed water drain pipe 62A. Such moisture adsorption and release action is continuously achieved by the rotation of the moisture adsorption element 65.

  That is, the moisture in the air humidified by the electrolyzed water in the sterilization apparatus 10 is adsorbed by the moisture adsorption element 65 in the moisture adsorption area, and then conveyed to the moisture release area by the rotation of the moisture adsorption element 65, where it is regenerated. It is absorbed by the air heated by the heater 67, condensed by the radiator 62, and finally received by the water tray 12 of the sterilization apparatus 10. As a result, the air that has been sterilized by the sterilization apparatus 10 and has been humidified is discharged into the vehicle after being dehumidified, so that the air in the vehicle can be sterilized efficiently.

  In this case, since the mist-like electrolyzed water is not diffused into the vehicle, the desiccant air conditioner 61 that functions as dehumidifying means after the air that has passed through the sterilizing apparatus 10 is once humidified by contact with the electrolyzed water. Therefore, even if the air in the vehicle, which is a relatively small space, is sterilized, the disadvantage that the air to be sterilized is humidified more than necessary is avoided. Is possible.

  As a result, the humidity inside the vehicle rises, and the inconvenience that visibility is deteriorated can be avoided by fogging the small space, in this embodiment, the window glass 22 constituting the vehicle. Therefore, in driving, visibility is improved and safety can be ensured. In addition, in a small space with a limited volume inside the vehicle, it is possible to avoid the inconvenience that the humidity increases abnormally, and it is possible to achieve air purification while suppressing an increase in the discomfort index.

  Furthermore, since it is possible to prevent or suppress inconvenience due to the occurrence of dew condensation, it is possible to avoid inconveniences that cause equipment failure by causing dew condensation to occur in the equipment installed in the vehicle. It becomes.

  Further, the water finally condensed in the heat exchanger 62 is received in the water tray 12 and can be reused as the electrolyzed water of the sterilization apparatus 10. Thereby, since it becomes possible to reduce the frequency | count of water supply per unit time from the water supply tank 15, the water supply interval from the outside to the water supply tank 15 can be extended, and the convenience is improved.

  In the fourth embodiment, the blower 63 that controls the ventilation into the main body 64 is installed on the air outflow side of the gas-liquid contact member 11 of the sterilization apparatus 10 and on the air inflow side of the moisture adsorption element 31. However, the arrangement position is not limited to this. For example, as shown in FIG. 20, it may be the discharge side of the moisture adsorbing element 31, that is, the discharge side of the main body 64, and as shown in FIG. 21, the heat exchanger 62 and the gas-liquid contact member of the sterilization apparatus 10 11 may be on the air inflow side of the heat exchanger 62, that is, the air suction side into the main body 64, as shown in FIG.

  Furthermore, in the said Example 4, although the gas-liquid contact member 11 of the microbe elimination apparatus 10 is provided in the air outflow side of the heat exchanger 62, it is not limited to this, FIG. 23 shows. Thus, the gas-liquid contact member 11 of the sterilization apparatus 10 may be provided on the air suction side of the heat exchanger 62.

  In any case, the air sucked into the main body 64 from the inside of the vehicle by the operation of the blower 63 passes through the gas-liquid contact member 11 of the sterilization apparatus 10 and then passes through the moisture adsorption element 31. After being sterilized and dehumidified, the vehicle is returned to the vehicle. The moisture adsorbed on the moisture adsorbing element 31 is regenerated by the regenerative heater 67, and the air containing the moisture flows into the heat exchanger 62 and is cooled by air to condense, and again the electrolyzed water. Can be used.

  Next, an in-vehicle air sterilization apparatus 80 as Example 5 of the air sterilization apparatus of the present invention will be described with reference to FIG. FIG. 24 shows a schematic configuration diagram of the air sterilizer 80. In the figure, the same reference numerals as those in FIG. 1 denote the same effects.

The sterilizing apparatus 83 includes a main body 86 that can store tap water therein, and a water absorbing member 87 is disposed in the main body 86. One end of the water absorbing member 87 is provided in contact with a gas-liquid contact member 11 (not shown), and the other end is provided so as to be immersed in the electrolyzed water stored in the main body 86. The water absorbing member 87 is configured to have substantially the same structure as the water absorbing member 27 in the first embodiment. Further, electrodes 88 and 89 configured in the same manner as the electrodes in the first embodiment are disposed in the main body 86, and are stored in the main body 86 by energizing the electrodes 88 and 89. The tap water is electrolyzed, whereby the active oxygen species is generated into electrolyzed water.

A heat exchanging portion 90 having a substantially U shape is connected.

  The heat exchanging portion 90 is a tubular member made of a heat-conducting material, and an endothermic surface 84A of the Peltier element 84 is disposed in a heat exchange manner on the forward path 90A connected to one end of the main body 86. Has been. On the other hand, a heat dissipation surface 84B of the Peltier element 84 is disposed in a heat exchange manner in a return path 90B of the heat exchanging portion 90 formed with one end opened to the inside of the vehicle.

  With this configuration, when the operation of the air sterilizer 80 is started, the water absorbing member 87 is electrolyzed in the main body 86 from the other end in a state of being immersed in the electrolyzed water in the main body 86 as in the above embodiment. Electrolyzed water sucked up by the water-absorbing member 87 is supplied to a gas-liquid contact member 11 (not shown) provided above by capillary action.

  The air-fluid contact member 11 moistened with the electrolyzed water is supplied with ventilation by the air blower 82 from the inside of the vehicle 86 into the main body 86. The air in the main body 86 comes into contact with the active oxygen species soaked in the gas-liquid contact member 11 and flows into the heat exchange unit 90 installed on the air downstream side of the gas-liquid contact member 11. The air flowing into the heat exchange unit 90 is cooled by the heat absorption surface 84A of the Peltier element 84 in the process of passing the forward path 90A, and moisture in the air is condensed on the inner wall surface of the heat exchange unit 90. Dehumidified. The dehumidified air is heated by the heat radiating surface 84B of the Peltier element 84 and discharged in the vehicle in the process of passing through the return path 90B of the heat exchange unit 90.

The condensed water received in the main body 86 is stored together with the electrolyzed water and reused as electrolyzed water.

  As described above, the air in the vehicle is passed through the sterilization apparatus 83 that holds the electrolyzed water, so that the air comes into contact with the electrolyzed water and the air in the vehicle is sterilized. Since the air that has passed through the sterilization device 83 is once humidified by contacting with the electrolyzed water, it is dehumidified by exchanging heat with the heat absorbing surface 84A of the Peltier element 84 that functions as a dehumidifying means. Even when the air in the vehicle, which is a small space, is sterilized, it is possible to avoid the disadvantage that the air to be sterilized is humidified more than necessary.

  In this case, the air in the vehicle is dehumidified and then heated up by exchanging heat with the heat radiating surface 84A of the Peltier element 84 disposed in the return path 90B of the heat exchanging unit 90, and then discharged into the vehicle. Therefore, it is possible to reduce the fluctuation of the air temperature after processing. As a result, the dehumidification can avoid the inconvenience that the in-vehicle temperature is remarkably lowered, and a comfortable in-vehicle space can be configured.

  In this embodiment as well, it is possible to avoid inconvenience that visibility deteriorates by increasing the humidity in the vehicle and fogging the small space, in this embodiment, the window glass 22 constituting the vehicle. Become. Therefore, in driving, visibility is improved and safety can be ensured. In addition, in a small space with a limited volume inside the vehicle, it is possible to avoid the inconvenience that the humidity increases abnormally, and it is possible to achieve air purification while suppressing an increase in the discomfort index.

  Furthermore, since it is possible to prevent or suppress inconvenience due to the occurrence of dew condensation, it is possible to avoid inconveniences that cause equipment failure by causing dew condensation to occur in the equipment installed in the vehicle. It becomes.

  In addition, the heat exchange part 90 in the present Example 5 may be comprised with the piping 92 filled with the hygroscopic agent 91 as a dehumidification means, as shown in FIG. The hygroscopic agent 91 is made of a material capable of adsorbing and removing vapor with silica gel, zeolite, or the like. Thereby, the air in a vehicle is ventilated by the sterilization apparatus 83 which hold | maintained the electrolyzed water, the said air contacts with electrolyzed water and the air in a vehicle is disinfected. The air that has passed through the sterilizing device 83 is once humidified by contacting with the electrolyzed water, and then dehumidified by passing through the moisture absorbent 91 that functions as a dehumidifying means. Even when the air is sterilized, it is possible to avoid the disadvantage that the air to be sterilized is humidified more than necessary.

  In this embodiment as well, it is possible to avoid inconvenience that visibility deteriorates by increasing the humidity in the vehicle and fogging the small space, in this embodiment, the window glass 22 constituting the vehicle. Become. Therefore, in driving, visibility is improved and safety can be ensured. In addition, in a small space with a limited volume inside the vehicle, it is possible to avoid the inconvenience that the humidity increases abnormally, and it is possible to achieve air purification while suppressing an increase in the discomfort index.

  Furthermore, since it is possible to prevent or suppress inconvenience due to the occurrence of dew condensation, it is possible to avoid inconveniences that cause equipment failure by causing dew condensation to occur in the equipment installed in the vehicle. It becomes.

In each of the above embodiments, it is desirable to adjust the concentration of the active oxygen species (hypochlorous acid) in the electrolytic water to a target concentration. The target concentration is set to a concentration that inactivates viruses or the like (for example, mold fungi) that are frequently present in the vehicle. In this case, for example, the concentration of hypochlorous acid in the electrolytic water is adjusted by changing the current flowing through the electrodes or the voltage applied between the electrodes. As an example, the concentration of hypochlorous acid can be changed to a high concentration by increasing the current flowing through the electrode (for example, 40 mA / cm ^{2 in} terms of current density). According to this, since it is only necessary to change the voltage applied to the electrode without using a new device or the like, cost reduction and space saving can be achieved.
