Description

  The present invention relates to an air cleaning device and an air cleaning device with a humidifying function that perform sterilization, deodorization, and removal of harmful substances by releasing water particles having high oxidizing power into a room.

  Indoor air contains various substances that are unpleasant or harmful to the human body, such as dust, pollen, and tobacco smoke. In recent years, since houses are airtight, such harmful substances are likely to stay indoors. For this reason, natural ventilation has been provided by opening windows in rooms as appropriate. However, it is the actual situation that natural ventilation cannot be performed as desired in areas where air pollution is severe, or in homes and workplaces where people suffer from hay fever. Under such circumstances, air purifiers that purify indoor air have become widespread.

  Recent air purifiers are provided with various functions such as removal of suspended dust and allergens, deodorization, and antibacterial functions. As means for realizing these, there are known a method in which various filters are provided at the air inlet and filtered or adsorbed, and a method in which radicals, ions, ozone, etc. having high oxidizing power are released into the air by discharge. Yes.

  Moreover, it is known that maintaining indoor humidity at 40 to 60% is effective in preventing influenza infection, and an air purifier with a humidifying function having a humidifying function is required.

  Conventionally, this type of sterilization / deodorization apparatus is provided with an air circulation means and an air flow rate adjustment means in a box having a divided air flow passage, and has an ozone generation means and an ozone decomposition means in one flow passage. On the other hand, the other flow passage is known to simply allow air to pass through. (For example, refer to Patent Document 1).

  As shown in FIG. 6, the sterilization / deodorization apparatus 101 includes a box 104 having a suction port 102 and a blower outlet 103, and a first passage 105 and a second passage 106 that are divided air flow passages. And a fan 107 for generating an air flow in the air flow passage. The suction port 102 includes a filter 108 that is a means for collecting dust and the like. After passing through the filter 108, the air is divided into a first passage 105 and a second passage 106 by a partition wall 109. An air amount adjusting means 110 is installed in the second passage 106. Depending on the open / closed state of the air amount adjusting means 110, the processing air amount of the entire apparatus and the flow rate ratio between the first passage 105 and the second passage 106. Can be adjusted. In the first passage 105, an ultraviolet lamp 111 for generating ozone and an ozone decomposition catalyst 112 are sequentially installed.

  When the air amount adjusting means 110 is closed, all of the processing air passes through the first passage 105 and the ozone decomposition catalyst 112 is present, so that the pressure loss is in a maximum state. Here, the treated air is sterilized by the action of ozone generated from the ultraviolet lamp 111 and ultraviolet rays, and the remaining ozone is decomposed by the ozone decomposition catalyst 112. The sterilized air is exhausted from the outlet 103 by the fan 107.

  When the air amount adjusting means 110 is open, most of the processing air passes through the second passage 106 because there is a difference in pressure loss between the first passage 105 and the second passage 106. In this case, the sterilization / deodorization efficiency is reduced as compared with the case where the air amount adjusting means 110 is closed, but the amount of treated air in the entire apparatus is increased, so that the room air is agitated. As a result, it is possible to provide a sterilization / deodorization apparatus suitable for use not only in the vicinity of the apparatus but also in a room with a large capacity.

  Further, as a conventional humidifier, an ionic wind inducing means for inducing an ionic wind, a humidifying element having water absorption, a water supply unit for supplying water to the humidifying element, and a blower using a fan are provided. Is known in which a humidifying element is disposed in the discharge side flow path and in the vicinity of the ion wind flow path. (For example, refer to Patent Document 2).

  As shown in FIG. 7, the conventional humidifier is provided with a filter 203 on the rear side of a main body 202 having a suction port 201, and a centrifugal fan 204 for blowing air on the rear side of the filter 203. And a motor 205 for driving the fan 204 are disposed. A humidifying element 206 and a water tank (not shown) are disposed above the fan 204, and the wind from the fan 204 passes through the humidifying element 206 to the outside through a blowout opening 207 that opens on the upper surface of the main body 202. Discharged.

  Below the space 208 between the suction port 201 and the filter 203, an ion wind inducing means 209 is installed. The ion wind inducing means 209 is configured as a discharge electrode block in which a discharge line and a counter electrode plate are arranged, and an air flow called ions and an ion wind is generated by applying a voltage to the discharge line. The ion wind passes through the space 208 upward from the second suction port 210 located below the suction port 201 and is discharged to the outside from the blowout port 207. In addition, a negative ion supply unit 211 including an ionization needle and a counter electrode plate is provided above the space 208. Air is ionized near the tip of the ionization needle, negative ions are generated, ion wind is guided, and purified air to which negative ions are added is discharged from the outlet 207 into the room.

  When water is supplied from the water tank to the humidifying element 206 and the fan 204 and the motor 205 are operated, the air that has passed through the filter 203 from the suction port 201 passes through the humidifying element 206 and is humidified from the outlet 207. Is discharged into the room. At this time, the amount of moisture vaporized from the humidifying element 206 is large, which is suitable as an operation mode when the humidity is very low.

  When the ion wind inducing means 209 is operated, the ion wind that flows from the second suction port 210 to the blowout port 207 flows. At this time, since the blowing sound is small and the amount of vaporization is small but humidification is performed, it is suitable as an indoor operation mode at night. By operating the negative ion supply unit 211, negative ions can be supplied indoors.

JP-A-1-221166 Japanese Patent No. 3731336

  The above-described conventional sterilization / deodorization apparatus can increase the amount of air discharged and promote the stirring of the indoor air in which the apparatus is installed, but the amount of generation of highly oxidizing components such as radicals and ions In order to increase the effects of sterilization, deodorization, and removal of harmful substances, a method for increasing the amount of components having high oxidizing power has been desired. Further, it has been difficult to prevent the contamination of the generation part where components having high oxidizing power such as radicals and ions are generated and to stably release components having high oxidizing power.

  In addition, the conventional humidifier uses a fan and ionic wind separately, and humidifies with a humidifying element to perform humidification operation when the humidity is very low, and operates the ion wind inducing means as a night operation mode. Thus, although the blowing sound is small and the amount of vaporization is small, it is humidified and can be used as an air purifier with a humidifying function capable of supplying negative ions into the room. However, it has not been possible to increase the amount of negative ions or components having high oxidizing power by humidifying the ion wind inducing means or the negative ion supply unit. Further, it has been difficult to prevent contamination of the ion wind excitation means and to stably generate negative ions and components having high oxidizing power.

  Therefore, the present invention solves the above-mentioned conventional problems, and relates to a device for sterilizing, deodorizing and removing harmful substances by releasing water particles with high oxidizing power, increasing the amount of components with high oxidizing power, It is an object of the present invention to provide an air cleaning device and an air cleaning device with a humidifying function that can operate stably.

And air blowing means for sending air to the air purification filter, and electrostatic spraying means for discharging water condensed on the electrode into the air as fine water particles containing radicals or ions having high oxidizing power by discharge. An air cleaning device, wherein the electrostatic spraying means has a Peltier element, an electrode in contact with the cooling surface of the Peltier element, and a heat dissipation fin in contact with the heat dissipation surface, and an amount of air passing through the heat dissipation fin of the electrostatic spraying means, This is greater than the amount of air that passes through the electrode. Further, only the air that has passed through the air purification filter is allowed to pass through the electrode of the electrostatic spraying means. As a result, the intended purpose can be achieved.

  According to the present invention, electrostatic spraying means for discharging water condensed on the electrode into the air as fine water particles containing radicals or ions having high oxidizing power by discharge is provided on the cooling surface of the Peltier element and the Peltier element. It has a heat dissipating fin that is in contact with the electrode and the heat dissipating surface, and the amount of air passing through the heat dissipating fin of the electrostatic spray means is larger than the amount of air passing through the electrode, so that more air flows through the heat dissipating fin Therefore, the heat exchange amount of the Peltier element can be increased and the cooling temperature of the Peltier element on the electrode side can be lowered.

  This makes it possible to increase the amount of water that condenses on the electrode, increases the amount of fine water particles containing radicals, ions, etc. that are generated from electrostatic spraying means by using a large amount of condensed water, and smells. The effect of being able to exhibit high performance against the removal of components, inactivation of allergens, viruses, etc., and sterilization of fungi, bacteria, etc. can be obtained.

  Moreover, since the water which condenses in the dry indoor environment where absolute humidity is low compared with the past can be ensured, the air purifier can be operated in a wider temperature and humidity range.

  Also, only the air that has passed through the air purification filter is allowed to pass through the electrode of the electrostatic spraying means, thereby preventing contamination of the electrode in which components having high oxidizing power such as radicals and ions are generated, and stably having high oxidizing power. The effect of releasing the components can be obtained.

  An air cleaning device and an air cleaning device with a humidifying function of the present invention include a main body having a suction port and a blower outlet, an air purification filter for purifying air in an air passage communicating the suction port and the blower outlet, Air provided with air blowing means for sending air to the air purification filter, and electrostatic spraying means for discharging water condensed on the electrodes into the air as fine water particles containing radicals or ions having high oxidizing power by discharge. A cleaning device, wherein the electrostatic spraying means has a Peltier element, an electrode in contact with the cooling surface of the Peltier element, and a heat dissipation fin in contact with the heat dissipation surface. This is characterized in that it is larger than the amount of air passing through.

  By circulating a large amount of air through the heat dissipating fins, it is possible to increase the heat exchange amount of the Peltier element and lower the cooling temperature of the Peltier element on the electrode side, so that the amount of water condensed on the electrode can be increased. Use more condensed water to increase fine water particles containing radicals and ions with high oxidizing power from electrostatic spraying means, remove odorous components, inactivate allergens, viruses, molds, bacteria, etc. High performance against sterilization. Moreover, since the water which dew condensation can be ensured also in the dry indoor environment where absolute humidity is lower than before, the air purifier can be operated in a wider temperature and humidity range.

  Further, a plurality of suction ports are provided, and at least one suction port is provided on the downstream side of the air purification filter. Since the air purification filter has a high pressure loss, by providing a suction port on the downstream side of the air purification filter, the amount of air introduced from the suction port on the downstream side of the air purification filter increases, and the amount of air discharged from the device is reduced. Can be increased. Thereby, the air purifying apparatus which can supply a component with high oxidizing power to the distant place of the room | chamber interior in which the air purifying apparatus was installed can be provided.

  Further, the suction port provided on the downstream side of the air purification filter is provided with a shutter. By opening and closing the shutter, it is possible to select whether the entire amount of air introduced into the apparatus is passed through an air purification filter to obtain clean air, or whether the amount of air discharged is increased through only a part of the air. Thereby, when there is much dirt of room air, the whole quantity of air can be passed through an air purification filter, and room air can be quickly cleaned. When the indoor air is less contaminated, it is possible to increase the amount of air discharged and supply a component having a high oxidizing power far away from the indoor air where the apparatus is installed.

  Further, a suction port on the downstream side of the air purification filter is provided on both side surfaces of the main body. In addition to the front side of the main body, air can be taken into the apparatus from both sides, and the amount of air discharged can be further increased. Moreover, the flow which sucks in air from the whole room centering on the apparatus can be created, and the indoor air can be efficiently cleaned.

  Further, only the air that has passed through the air purification filter is allowed to pass through the electrode side of the electrostatic spraying means. As a result, it is possible to prevent contamination of the electrode where components having high oxidizing power such as radicals and ions are generated, and to stably release components having high oxidizing power.

  Further, the electrostatic spraying means is arranged on the downstream side of the air blowing means. Fine water particles containing radicals and ions with high oxidizing power generated from the electrostatic spraying means do not collide with the blowing means and disappear, and are diffused into the room by blowing from the air outlet into the room. High performance is exhibited against removal of odorous components adhering to the curtains and curtains, inactivation of allergens and viruses floating or adhering to the room, and sterilization of molds and bacteria.

  Further, the electrostatic spraying means is arranged in the vicinity of the air outlet. By shortening the distance between the electrostatic spraying means and the air outlet, the disappearance of fine water particles containing radicals and ions with high oxidizing power is minimized, and more fine water particles are discharged from the air outlet indoors. Can be released.

  In addition, an air outlet is provided above the heat dissipating fin. Since the air heated by the heat radiating fins causes an upward air flow, the air that has been warmed is released to the outside of the apparatus by providing an air outlet that opens upward, so that heat can be efficiently radiated.

  Further, the air outlet is provided with a wind direction guide plate. By adjusting the angle of the wind direction guide plate, air containing fine water particles containing radicals and ions having high oxidizing power can be blown out in an arbitrary direction.

  Further, the air outlet can be opened and closed by a wind direction guide plate of the air outlet. By closing the wind direction guide plate when the apparatus is stopped, it is possible to prevent dirt from adhering to the inside of the main body or the electrostatic spraying means.

  In addition, the air that has not been passed through the air purification filter sucked from the suction port and the air that has passed through the air purification filter are mixed and passed through the radiation fins. By allowing more air to flow through the heat dissipating fins, the amount of water condensed on the electrodes can be increased because the amount of heat exchange of the Peltier elements can be increased and the cooling temperature of the Peltier elements on the electrode side can be lowered. Use more condensed water to increase fine water particles containing radicals and ions with high oxidizing power from electrostatic spraying means, remove odorous components, inactivate allergens, viruses, molds, bacteria, etc. High performance against sterilization.

  In addition, an air flow rate adjusting means for adjusting a flow rate of air sucked from a plurality of air suction ports is provided. The amount of air that passes through the air purification filter and the amount of air that does not pass can be adjusted according to the contamination state of the air sucked from the suction port. Thereby, when there is much dirt of room air, room air can be quickly cleaned by increasing the amount of air passed through the air purification filter. When the indoor air is less contaminated, the amount of air that does not pass through the air purification filter is increased to increase the amount of air discharged, and a component having a high oxidizing power can be supplied far away from the indoor air in which the apparatus is installed.

  Further, the humidifying means is provided upstream of the electrostatic spraying means. Even when the indoor air is dry, humidified air can be supplied to the electrostatic spraying means, and the condensed water can be efficiently collected on the electrodes.

  Further, the humidified air is supplied to the electrode side of the electrostatic spraying means. Even when the indoor air is dry, humidified air can be supplied to the electrostatic spray electrode, and condensed water can be efficiently collected on the electrode.

  Further, the humidifying means for humidifying the air is a humidifying filter, comprising a water storage tray for arranging the humidifying filter, and a water supply means for supplying water to the humidifying filter. Is. If humidification is performed by an ultrasonic method or a heating evaporation method as the humidifying means, excessive humidification occurs, and excessive water droplets adhere to the electrode and the surrounding wall, and the discharge of the electrode tends to become unstable. On the other hand, when the vaporization type humidifying means is used, since natural evaporation from the humidifying filter is used, excessive humidification can be avoided and appropriate and stable humidification can be performed.

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

(Embodiment 1)

The electrostatic spraying means 8 includes a Peltier element 9, an electrode 10 in contact with the cooling surface of the Peltier element, and a heat radiation fin 11 in contact with the heat radiation surface. The suction opening 1 can change an opening area by moving a front face decorative plate 12 having a substantially vertical rectangular flat plate shape provided with a predetermined distance on the front surface of the main body 4 up and down. The air cleaning means is a vertically long box-shaped air purification filter 6 formed by folding a glass fiber dust collecting filter medium into a bellows shape, and is provided inside a drying air passage 5 that communicates the suction port 1 and the air outlet 3. ing. The electrostatic spraying means 8 is provided in the vicinity of the blower outlet 3 in the downstream portion of the fan 7 as the blower means, and the upper portion of the heat radiation fin 11 is opened as the blower outlet 3.

  The operation of the air cleaning device having such a configuration will be described.

  By moving the fan 7 as a blowing means, air is sucked into the main body 4 from the suction port 1 and the sub suction port 2. Here, the air that has passed through the suction port 1 passes through the air purification filter 6, the fan 7, and the electrostatic spraying means 8 and is discharged from the air outlet 3. The air that has passed through the sub suction port 2 passes through the fan 7 and the electrostatic spraying means 8 and is discharged from the air outlet 3.

  As shown in FIG. 3, the electrostatic spraying means 8 includes a Peltier element 9, an electrode 10 in contact with the cooling surface of the Peltier element 9, and a radiation fin 11 in contact with the radiation surface. The Peltier element 9 is fixed to a resin plate constituting a part of the main body 4, and the electrode 10 and the radiation fin 11 are in contact with the air path, respectively. The heat dissipating fin 11 has an uneven shape protruding from the resin plate, and can efficiently dissipate heat to the air sucked into the main body 4. The electrode 10 is composed of an elongated columnar spray electrode 14 and a ring-shaped counter electrode 15 provided at a position opposed to each other at a predetermined distance, and a high voltage is applied between them. For example, when the counter electrode 15 is grounded to 0 V, and the spray electrode 14 is cooled and condensed water is attached, a voltage of −6 kV is applied from the high voltage application unit, whereby the oxidizing power from the spray electrode 14 is high. Fine water particles containing radicals and ions can be released.

  By circulating a large amount of air through the radiation fins 11 of the electrostatic spraying means 8, the amount of heat exchange of the Peltier element can be increased to lower the cooling temperature of the Peltier element on the electrode side, and water condensed on the spray electrode 14 can be reduced. The amount can be increased. Use more condensed water to increase fine water particles containing radicals and ions with high oxidizing power from electrostatic spraying means, remove odorous components, inactivate allergens, viruses, molds, bacteria, etc. High performance against sterilization. In addition, water that is condensed in an environment where the absolute humidity is low can be secured, so that the apparatus can be operated in a wider temperature and humidity range. In addition, since there is an optimum value for the discharge of condensed water depending on the amount of condensed water, a discharge current is detected, a signal is sent to the control unit, and a voltage is applied from the control unit to the high voltage application unit at an appropriate timing. By applying, fine water particles containing radicals and ions having high oxidizing power can be generated stably.

  As a method for circulating a large amount of air through the radiating fins 11 of the electrostatic spraying means 8, the cross-sectional area of the air passage where the electrodes 10 are installed is smaller than the cross-sectional area of the air passage where the radiating fins 11 are installed. The method of doing is mentioned. You may install what increases pressure loss, such as a resin net | network, in the inlet of the air channel in which the electrode 10 was installed.

  A plurality of sub suction ports 2 that are the suction ports on the downstream side of the air purification filter may be provided. For example, they may be provided on both side surfaces and the back surface of the main body 4.

(Embodiment 2)
In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 4 and 5, the air cleaning device with a humidifying function according to the second embodiment of the present invention has a main body 4 having a plurality of air inlets 1, sub-inlet ports 2 and air outlets 3. And an air purification filter 6 for purifying the air in the middle of the drying air passage 5 and the humidification air passage 16 communicating with the air inlet 1 and the air outlet 3, and a humidifying filter as a humidifying means for humidifying the air 17, a fan 7 as air blowing means for sending air to the air purification filter 6 and the humidifying filter 17, and water condensed on the electrodes as fine water particles containing radicals and ions having high oxidizing power by discharge And an electrostatic spraying means 8 to be discharged therein. The humidification filter 17 is installed on the water storage tray 18 for holding water, and is in a wet state when water is supplied from a water tank (not shown) as water supply means. The humidifying filter 17 is made of a water-absorbing material, and a sufficient amount of water is sucked up from the water storage tray 18 onto the humidifying filter 17, and humidification is performed by the sucked water coming into contact with the air passing through the humidifying filter 17.

  As the water-absorbing material used for the humidifying filter, non-woven fabrics / woven fabrics using fibers having an official moisture content of 0.4% or more, ceramics, paper, water-absorbing processed resin plates, and the like can be used. Synthetic fibers include polyester, acrylic, nylon, vinylon, rayon, polynosic, cupra, acetate, triacetate, promix and the like. Examples of natural fibers include silk, hair, cotton, and hemp. The fiber may be a fiber whose surface has been subjected to ultraviolet laser irradiation or sputter etching treatment to form irregularities by ablation or etching of the fiber. Moreover, you may carry | support particle | grains, such as a silica gel and resin, on the fiber surface.

  When the humidifying filter is a water-retaining knitted fabric in which yarn is knitted, a humidifying filter having both water absorption and durability can be obtained. The humidifying filter made of a knitted fabric can wash dirt adhered by washing with water, and can maintain the performance for a long time without deteriorating the humidifying performance.

  In addition to the vaporization method using a humidification filter, an ultrasonic method, a heating evaporation method, a two-fluid nozzle spray method, or a water crushing method may be used as the humidifying means. If humidification is performed using an ultrasonic method or heating evaporation method as the humidifying means, excessive humidification will occur, and excessive water droplets will adhere to the electrode and surrounding walls, making the discharge of the electrode unstable. It is preferable to use it. In the case of the vaporization type, since natural evaporation from the humidifying filter is used, excessive humidification can be avoided and appropriate and stable humidification can be performed.

  The upper portion of the humidifying filter 17 includes a partition wall 19 that divides the humidified air passage 16 for sending humid air and the drying air passage 5 for sending unhumidified air, and the humidified air passage 16 and the drying air passage extended from the partition wall 19. The damper 20 which adjusts the mixing amount of the air which passes 5 is provided. 4 shows a state in which the damper 20 is closed, FIG. 5 shows a state in which the damper 20 is opened, and a broken line indicates a trajectory in which the damper 20 can move.

  When the damper 20 is closed, a part of the air introduced into the main body from the suction port 1 is removed from the dust, dust and chemical substances by the air purification filter 6 and passes through the humidification filter 17 to become humidified air. After passing through the fan 7 via the humidified air passage 16, it passes around the electrode 10 constituting the electrostatic spraying means 8, and is discharged into the room from the outlet 3 along the wind direction guide plate 13. Here, since only the air that has passed through the air purification filter 6 is supplied to the electrode 10, dirt is not attached to the electrode 10 in which components having high oxidizing power such as radicals and ions are generated, and the electrode 10 is stably oxidized. A powerful component can be released. Further, by providing the humidifying filter 17 as the humidifying means on the upstream side of the electrostatic spraying means 8, the humidified air is supplied to the electrode 10 of the electrostatic spraying means 8 even when the indoor air is dry. The dew condensation water can be efficiently collected on the spray electrode 14 of the electrode 10. At the same time, the remaining air introduced into the main body from the suction port 1 is removed of dust, dust and chemicals by the air purification filter 6, passes through the fan 7 through the drying air passage 5, and then is electrostatically sprayed means 8. Passes through the periphery of the heat dissipating fins 11, and is discharged into the room from the air outlet 3 along the wind direction guide plate 13. Further, when a shutter is provided at the sub suction port 2 and the shutter is opened, air into the main body is introduced. The air introduced into the main body from the sub suction port 2 passes through the fan 7 through the drying air passage 5, then passes around the radiation fins 11 constituting the electrostatic spraying means 8, and follows the wind direction guide plate 13. Then, the air is discharged into the room from the air outlet 3. Since the air introduced from the suction port 1 and the sub suction port 2 is mixed and passes around the radiating fin 11, the amount of passing air is larger than when the shutter of the sub suction port 2 is closed. With this configuration, it becomes easy to increase the amount of air that passes through the heat dissipating fins 11 of the electrostatic spraying means 8 than the amount of air that passes through the electrode 10. By circulating a large amount of air through the heat dissipating fins, it is possible to increase the heat exchange amount of the Peltier element and lower the cooling temperature of the Peltier element on the electrode side, so that the amount of water condensed on the electrode can be increased. Use more condensed water to increase fine water particles containing radicals and ions with high oxidizing power from the electrostatic atomizer, remove odorous components, inactivate allergens, viruses, mold, bacteria High performance is demonstrated against sterilization. In addition, since it is possible to secure water that is condensed even in an environment where the absolute humidity is lower than that in the past, the apparatus can be operated in a wider temperature and humidity range.

  When the damper 20 is opened and the auxiliary suction port 2 is also opened, the air introduced from the suction port 1 and passed through the air purification filter 6 around the radiating fin 11 and the air purification filter 6 introduced from the suction port 1 Since the air that has passed through the humidifying filter 17 and the air that has been introduced from the sub-suction port 2 are mixed and passed, the amount of passing air can be further increased.

  Further, by adjusting the opening / closing degree of the damper 20 after closing the auxiliary suction port 2, the ratio of the amount of air passing around the radiating fin 11 and the amount of air passing around the electrode 10 can be adjusted. The operation according to the temperature and humidity of the intake air becomes possible.

  The air purifier with a humidifying function according to the present invention has a high oxidizing power generated from the electrostatic spraying means by increasing the amount of air passing through the heat dissipating fins of the electrostatic spraying means than the amount of air passing through the electrodes. Fine water particles containing radicals and ions can be increased. In addition, since it is possible to secure water that condenses in an environment where the absolute humidity is low as compared with the conventional case, the apparatus can be operated in a wider temperature and humidity range. In addition, by passing only the air that has passed through the air purification filter through the electrode of the electrostatic spraying means, it is possible to prevent contamination of the generating part where components having high oxidizing power such as radicals and ions are generated, and to stably generate oxidizing power. The effect of releasing high components can be obtained. By these actions, water particles with high oxidizing power can be discharged into the room to sterilize, deodorize and remove harmful substances. Useful for air purifiers, air purifiers with humidifying functions, air conditioners, cold air fans, etc. It is.
