It is the structure which passes -41F2.

The gas-liquid contact members 41A1 to 41F2 are members that bring electrolyzed water into contact with the air passing through the air passage 120A, and the air flowing through the air passage 120A in these gas-liquid contact members 41A1 to 41F2 includes an electrolysis that includes a predetermined active oxygen species. By contact with water, viruses contained in the air are inactivated and air is sterilized.

And a control unit 65 for controlling the operation of the above.

A water supply pipe 57 for supplying city water (tap water) or the like to the water storage tank 51 and a water supply valve 58 are connected to the water storage tank 51, and the water supply valve 58 is connected to a float switch FS provided in the water storage tank 51. Based on the operation, the controller 65 controls the opening and closing. Here, the water supply source connected to the water supply pipe 57 and supplying water to the water storage tank 51 may be either city water (tap water) or water stored in a water supply tank. The water stored in the water tank or the like may be water that contains ion species such as chloride ions in advance, such as tap water, or a dilute concentration of chloride ions such as well water. When water is used, the water may be adjusted to tap water by adding chloride ions to the water. In the present embodiment, these are collectively referred to as water.
In this configuration, even when dilute water having a chloride ion concentration such as well water is used for the water storage tank 51, in order to add chloride ions to this water, it is adjusted to a predetermined concentration in advance. A salt water tank 59 storing salt water is provided, and a supply pump 61 is connected to the salt water tank 59 via a salt water supply pipe 60, and the salt water in the salt water tank 59 is supplied by the supply pump 61. It is supplied to the water storage tank 51. A check valve 62 is provided in the saline solution supply pipe 60 connected to the water storage tank 51. The supply pump 61 is configured to operate under the control of the control unit 65 based on the conductivity detected by the electrolysis unit 52, for example.
Note that the electrolyte added to the water in the water storage tank 51 in order to efficiently generate active oxygen species is not limited to salt, and other electrolytes can be used. For example, calcium chloride or magnesium chloride is used. It is also possible to use halogen-containing salts containing other halogens, and various halogenates of chlorine and other halogens, and electrolytes containing no halogen may be used. These electrolytes are preferably water-soluble.

  Moreover, in this embodiment, the electrolyzed water supply pipe 56 connected to the connection port of the water storage tank 51 is branched into six electrolyzed water supply pipes 56A to 56F, respectively. The electrolytic water supply pipes 56A to 56F are divided almost evenly. The electrolyzed water supply pipes 56A to 56F supply electrolyzed water to the element units 40A to 40F, respectively. The electrolyzed water supplied by the electrolyzed water supply pipes 56A to 56F is infiltrated into the gas-liquid contact members 41A1 to 41F2, flows down from these gas-liquid contact members 41A1 to 41F2, is collected in the drain pan 44, and passes through the circulating water return pipe 55. To the water storage tank 51.

The electrolysis unit 52 is fixedly disposed on the side surface of the water storage tank 51. Specifically, the electrolysis unit 52 includes a bottomed cylindrical main body case and at least a pair of electrode plates 72 and 73 housed in the main body case, and applies a voltage between the electrode plates 72 and 73. As a result, the water is electrolyzed to generate electrolyzed water containing active oxygen species.
Here, the reactive oxygen species are oxygen molecules having an oxidation activity higher than that of normal oxygen and related substances, and so-called narrow definition such as superoxide anion, singlet oxygen, hydroxyl radical, or hydrogen peroxide. These active oxygens include so-called broad active oxygens such as ozone and hypohalous acid.

The electrode plates 72 and 73 are, for example, two electrode plates whose bases are made of titanium (Ti), and on the surfaces thereof, a film layer containing iridium (Ir) and platinum (Pt), respectively. It has a coating layer containing.
When a voltage is applied between the electrode plates 72 and 73, the cathode electrode (cathode) reacts as shown in the following formula (1).
2H ₂ O + 2e ⁻ → H ₂ + 2OH ⁻ (1)
The anode electrode (anode) reacts as shown in the following formula (2).
2H ₂ O → O ₂ + 4H ⁺ + 4e ⁻ (2)
When the reactions at the cathode and anode electrodes are combined, water is electrolyzed as shown in the following formula (3).
2H ₂ O → 2H ₂ + O ₂ (3)
Along with this reaction, in the anode electrode, chlorine ions (chloride ions: Cl ⁻ ) contained in water react as shown in the following formula (4) to generate chlorine (Cl ₂ ).
2Cl ⁻ → Cl ₂ + 2e ⁻ (4)
Further, this chlorine reacts with water as shown in the following formula (5) to generate hypochlorous acid (HClO) and hydrogen chloride (HCl).
Cl ₂ + H ₂ O → HClO + HCl (5)

  Hypochlorous acid (active oxygen species in a broad sense) generated at the anode electrode has a strong oxidizing action and bleaching action. An aqueous solution in which hypochlorous acid is dissolved, that is, electrolyzed water generated by the electrolysis unit 52 exhibits various air cleaning effects such as inactivation of viruses and the like, sterilization, and decomposition of organic compounds. Thus, when the electrolyzed water containing hypochlorous acid flows through the electrolyzed water supply pipes 56A to 56F and is dropped onto the gas-liquid contact members 41A1 to 41F2 through the watering box, the air blown out by the use side blower 22 Comes into contact with hypochlorous acid in the gas-liquid contact members 41A1 to 41F2. As a result, viruses or the like floating in the air are inactivated, and odorous substances contained in the air react with hypochlorous acid to be decomposed or ionized and dissolved. Accordingly, the air is sterilized and deodorized, and the purified air is discharged from the gas-liquid contact members 41A1 to 41F2.

  An example of influenza virus is given as an action mechanism for inactivating viruses and the like by reactive oxygen species. The above-mentioned reactive oxygen species have the action of destroying and eliminating (removing) the surface protein (spike) of the virus, which is essential for influenza virus infection. When this surface protein is destroyed, the influenza virus and the receptor (receptor) necessary for the infection of the influenza virus are not bound, and the infection is prevented. For this reason, the influenza virus floating in the air loses infectivity by contacting the electrolyzed water containing active oxygen species in the gas-liquid contact members 41A1 to 41F2, thereby preventing infection.

  Therefore, by disposing the element units 40A to 40F including the gas-liquid contact members 41A1 to 41F2 in the sterilization chamber 120 of the rooftop air conditioner 110, the air passing through the sterilization chamber 120 is allowed to pass through the gas-liquid contact member 41A1. As shown in FIG. 1, the sterilized air can be widely distributed in the movie theater 100, and air sterilization and deodorization in a large space facility can be easily and efficiently performed. Can be done well.

Here, switching of the electrodes for applying a positive potential to any side of the electrode plates 72 and 73 in the electrolysis unit 52 can be performed by reversing the polarity of the electrodes. In this embodiment, the control unit It can be executed by changing (reversing) the voltage applied to the electrode plates 72 and 73 by 65.
Further, the concentration of the active oxygen species in the electrolyzed water is adjusted to a concentration that inactivates viruses to be sterilized under the control of the control unit 65. The concentration of the active oxygen species is adjusted by adjusting a voltage applied between the electrode plates 72 and 73 and adjusting a current value flowing between the electrode plates 72 and 73. For example, when a positive potential is applied to the electrode plate 72 and the current value flowing between the electrode plates 72 and 73 is 20 mA (milliampere) / cm ² (square centimeter), the predetermined free residual chlorine concentration (for example, 1 mg) (Milligram) / l (liter)). Moreover, the density | concentration of hypochlorous acid in electrolyzed water can be adjusted to a high density | concentration by changing the voltage applied between the electrode plates 72 and 73, and making current value high.

  Further, the water storage tank 51 is provided with a drain pipe 67 for draining the water in the water storage tank 51 by a siphon method. The drain pipe 67 includes a first vertical portion 67A extending upward from the bottom of the water storage tank 51, a horizontal portion 67B extending in a substantially horizontal direction connected to the first vertical portion 67A, and a lower portion outside the tank connected to the horizontal portion 67B. A second vertical portion 67C extending. The horizontal portion 67B is provided at a position slightly higher than the control water level in the normal water storage tank 51. By opening the water supply valve 58 and supplying water to this height position, the horizontal portion 67B is stored in the water storage tank 51 according to the principle of siphon. Water is discharged.

As shown in FIG. 6, the case 50 of the electrolytic water circulation supply unit 5 is a rectangular parallelepiped, the upper surface is a detachable lid 50 </ b> A, and two of the other side surfaces are a detachable pipe drawer panel 50 </ b> B, and electrical equipment It is a box side panel 50C, and the other side surface and the bottom surface 50D are joined together.

The piping drawer panel 50B corresponds to the side surface on the side where the water storage tank 51 is installed, and has a plurality of holes through which various pipes connected to the outside of the electrolytic water circulation supply unit 5 and the water storage tank 51 pass. Further, the electrical box side panel 50C is a side facing the side opposite to the sterilization chamber 120 (FIG. 5), and is screwed into the pipe drawing panel 50B and the cover attaching portion 50E formed on the face facing the pipe drawing panel 50B. It has been stopped.
The lid 50A is fixed by a screw (not shown) or the like, and can be opened by removing the screw. In the opened state of the lid 50 </ b> A, it is possible to access various parts such as the electrical equipment box 30, the water storage tank 51, the water supply pump 53, the salt water tank 59, and the supply pump 61 housed in the case 50.

  The lid 50A covers the upper surface of the case 50 and the upper ends of the side surfaces in order to prevent rainwater and dust from entering the electrolytic water circulation supply unit 5 installed outdoors. For this reason, when removing the piping drawer panel 50B and the electrical equipment box side panel 50C, the cover 50A is first removed. When the lid 50A is removed, the electrical box side panel 50C is initially removable, and when the electrical box side panel 50C is removed, the piping drawer panel 50B is removable.

When the electrical box side panel 50C (service panel) is removed, one side surface of the case 50 is opened, and an electrical box cover 30A (cover) constituting one side surface of the rectangular electrical box 30 is exposed, and this electrical box cover 30A is exposed. Can be removed to the electrical box side panel 50C side. In the electrical box 30, a power supply circuit unit (electric circuit) that supplies power to the control board 31, the electrolytic unit 52, the water pump 53, the supply pump 61, and the like on which the microcomputer constituting the control unit 65 (FIG. 4) is mounted. Part) 33 and the like are accommodated. When the electrical box cover 30A is removed, one side surface of the electrical box 30 is opened, and access to the control board 31, the power supply circuit unit 33, and the like housed in the electrical box 30 becomes possible.
Thus, when the cover 50A is removed and the electrical box side panel 50C is removed, the electrical box cover 30A is exposed, and the interior of the electrical box 30 can be accessed by removing the electrical box cover 30A. Thereby, the maintenance of the electrical equipment box 30 can be performed very easily.

In the case 50, a water storage tank 51 and a salt water tank 59 are arranged side by side, and an electrical box 30 that is a longitudinal box is arranged along the direction in which the water storage tank 51 and the salt water tank 59 are arranged. Yes.

A supply pump 61 (aqueous solution supply pump) and A water pump 53 (electrolyzed water supply pump) is installed side by side, the supply pump 61 is located on the saline tank 59 side, and the water pump 53 is located on the water storage tank 51 side.
Here, since the electrical box 30 is fixed at a position floating from the bottom surface 50D, water, electrolytic water, or salt water that has leaked or overflowed from each part in the case 50 cannot enter the electrical box 30. Therefore, the control board 31 and the power supply circuit unit 33 can be reliably protected, and the power supply circuit unit 33 and the like can be stored in the same case 50 as the water storage tank 51 and the saline tank 59.

The supply pump 61 has a suction port 61A connected to the inside of the saline tank 59 via the saline supply pipe 60, and a discharge port 61B connected to the salt solution inlet 85 of the water storage tank 51, and sucks from the suction port 61A. The salt solution is discharged from the discharge port 61B. The leg portion 61C of the supply pump 61 is fixed to the bottom surface 50D. The water feed pump 53 has a suction port 53A for sucking in the electrolyzed water in the water storage tank 51 and a discharge port 53B for discharging the electrolyzed water sucked from the suction port 53A to the water feed pump 53. Here, a part of the electrolyzed water discharged from the discharge port 53B branches and is supplied to the electrolysis unit 52 as described later. The leg portion 53C of the water pump 53 is fixed to the bottom surface 50D.
An electrolysis unit 52 is attached to the surface of the water storage tank 51 on the side of the electrical box 30, and a salt water supply part 85 into which the salt water sent out by the supply pump 61 is input, and electrolysis that supplies the electrolyzed water in the water storage tank 51. A water supply port 88 is disposed. Therefore, by installing the supply pump 61 on the saline tank 59 side and the water pump 53 on the water storage tank 51 side below the electrical box 30, the length of the pipe laid between each tank and the pump is shortened. Can be handled without waste. Specifically, the pipes of the branch pipe 54, the electrolytic water supply pipe 56, the salt water supply pipe 60, and the drain pipe 67 shown in FIG. 4 are all located below the electrical box 30 or the electrical box 30 and the water storage tank. 51 and a saline solution tank 59.

On the other hand, the power supply circuit unit 33 supplies a drive current for operating the electrolysis unit 52, the water supply pump 53, and the supply pump 61 according to the control of the control unit 65. For this reason, the current output from the power supply circuit unit 33 is larger than that of the control board 31, and the wiring to be connected corresponds to the large current. For this reason, the wiring extending from the power supply circuit 33 to each part is thicker than the wiring extending from the control board 31 to each part, is difficult to handle, and is generally expensive. Therefore, by arranging the power supply circuit section 33 on the water storage tank 51 side, the wiring length from the power supply circuit section 33 to the electrolysis unit 52 and the water pump 53 can be shortened, and the ease of wiring is increased. Cost can be reduced.

  As shown in FIG. 6, the water storage tank 51 does not have a lid, and the inside of the water storage tank 51 is exposed when the lid 50 </ b> A of the case 50 is opened.

The overflow discharge port 81 is an opening through which the electrolytic water is discharged to the overflow pipe 68 (FIG. 5) when the level of the electrolyzed water in the water storage tank 51 exceeds the height of the overflow discharge port 81. The circulating water return port 84 is an opening to which the circulating water return pipe 55 from the sterilization chamber 120 is connected. Further, the drainage port 82 is an opening for forcibly draining the entire amount of electrolyzed water in the water storage tank 51 during maintenance, and is fitted with a cock that is manually opened and closed.

  The interior of the water storage tank 51 is partitioned by a partition wall 64, and a through hole is provided in the partition wall 64, and a scale filter 66 is attached to the through hole. That is, the inside of the water storage tank 51 is divided into a chamber on the electrolysis unit 52 side and a chamber on the electrolyzed water supply port 88 side by the scale filter 66, and the electrolyzed water is transferred from the chamber on the electrolysis unit 52 side to the other chamber. Flowing through. In the chamber on the downstream side of the scale filter 66, a plurality of float switches FS are attached at different height positions.
