  The operation of the above configuration will be described. First, the air cleaner is operated by operating various switches of the display / operation means 2 of the air cleaner in a state where power is supplied from a power source (not shown). In the activated air purifier, the air blowing path F, which is the air flow, is formed from the air blowing means 3 from the air inlet to the outlet 8.

In the air passage F, the indoor air taken into the main body 1 from the air inlet passes through the filter device, whereby dust and the like in the indoor air are collected and cleaned. Subsequently, the air that has passed through the filter device and has been purified is sent to the discharge port 8 through the air purifier body 6 by the blower 3. The purified air is mist together with a mist M of a picometer size (where picometer = pm = 10 ⁻¹² meter) generated by an electrostatic atomizer 6 disposed on the discharge port 8 side. It is discharged into the room from the discharge outlet 11. Then, the air containing the mist M discharged from the mist discharge port 11 rides on the air blowing path F and diffuses into the room. The indoor air is purified by continuing the above air flow.

  Here, generation of picometer-sized mist M by the electrostatic atomizer 6 will be described. In the electrostatic atomizer 6, voltage application means 25 (not shown) is provided between the discharge electrode 17 and the counter electrode 18. ) Is applied to the tip of the discharge electrode 17, and the Coulomb force is generated between the water sucked from the water tank 16 to the tip of the discharge electrode 17 by the capillary phenomenon and the counter electrode 18. Water is charged by the action of this, and when this Coulomb force exceeds the surface tension of water, water repeats splitting (Rayleigh splitting), radicals such as OH radicals (hydroxy radicals or hydroxyl radicals) (radical or free radicals, It generates mist M having a particle size of picometer size containing a free radical) active species.

  In this case, by forming the discharge electrode 17 from an aggregate of porous polyesters having countless pores smaller than the pores of the porous ceramic, for example, as described above, the water is very small due to the capillary phenomenon. It is sucked up so as to ooze out from the hole to the tip of the discharge electrode 17. Further, when a voltage is applied between the discharge electrode 17 and the counter electrode 18 by forming the tip of the discharge electrode 17 in an arc shape so that the counter area of the discharge electrode 17 facing the counter electrode 18 is increased. The charge concentration at the tip of the discharge electrode 17 is reduced. Then, by reducing the concentration of charge at the tip of the discharge electrode 17, water is gradually split with a weak charge to generate a picometer-sized mist M having a finer particle diameter than the nanometer size. Is possible.

  And by making the particle diameter of the mist M generated by the electrostatic atomizer 6 of this embodiment a picometer size, it becomes easier to ride the flow of the cleaned air, and the diffusibility is improved. Therefore, active species such as radicals (radical or free radicals, free radicals) such as OH radicals (hydroxy radicals or hydroxide radicals) contained in the picometer-sized mist M generated by the electrostatic atomizer 6 in the indoor air Effective sterilization / deodorization can be performed over a wide range by effectively utilizing the sterilization / deodorization function for floating components and deposits on the wall of the room.

Not only the water tank 16 can be attached and detached, but also the main body case 19 can be removed as necessary. Therefore, the main body case 19 of the electrostatic atomizer 4 is left in the air purifier main body 6 so that only the water tank 16 can be removed, so that only the water tank can be detached and water can be easily replenished. In addition, the water tank 16 can be made smaller and can be easily removed from the air cleaner body 6. Further, since the water tank 16 and the main body case 19 are not integrated in the electrostatic atomizer 4, the main body case 19 can be easily removed while leaving the water tank 16 in the air purifier main body 6. In addition, it is possible to easily perform the removal and the like of removing water accumulated in the discharge electrode 17 and the like.

  Further, the main body case 19 of the electrostatic atomizer 4 is detachably provided in the air cleaner main body 6 from the mist discharge port 11 which is a direction different from the attaching / detaching direction of the water tank 16, thereby finely supplying water. As a method for removing the mechanism, the water tank 16 is left in the air purifier main body 6 by being provided so as to be removable from the mist discharge port 11 direction other than the direction of the tank take-out port 14 which is the attaching / detaching direction of the water tank 16. Since only the main body case 19 can be removed as it is, the main body case 19 can be easily removed at the time of cleaning such as removal of water accumulated in the main body case 19 and the discharge electrode 17.

  In addition, the electrostatic atomizer 4 generates the picometer-sized mist M, thereby disinfecting the suspended components in the indoor air and the deposits on the indoor wall by the picometer-sized mist M. By effectively utilizing the deodorizing function, effective sterilization and deodorization can be performed over a wide range.

Further, by making the small diameter mist M picometer size, it is easy to ride on the wind, and the small diameter mist M can be carried far away. Furthermore, the convenience of the water supply work of the water tank 16 can be improved by dividing the main body case 19 and the water tank 16. In addition, a water supply member 22 that draws water into the main body case 19 is provided at the introduction port 21, but by disposing a descaling agent 26 in the water tank 16 , the water supply member 22 and the electrostatic atomizer 4 It is possible to suppress the adhesion of chalk to the discharge electrode 17 and the counter electrode 18 that constitute the electrode part, and it is possible to extend the life of the electrostatic atomizer 4.

  FIG. 11 shows the appearance of the air cleaner. The air cleaner body 6 is provided with the operation means 2 at the top and the front panel member 7 formed detachably on the front surface of the air cleaner body 6, and a dehumidification tank 35 provided in the dehumidification means 32, The humidifying tank 36 of the means 33 is detachably attached to the air cleaner body 6 independently of each other.

  Here, the dehumidifying means 32 in the present embodiment may be configured to store the condensed water collected in the air purifier main body 6 after dehumidification in the dehumidifying tank 35, and the dehumidifying method also uses a compressor as a compressor. It can be applied to compressor type (refrigeration cycle type), desiccant type (zeolite type, silica gel type), hybrid type combining compressor type and desiccant type.

  Further, the humidifying means 33 in the present embodiment only needs to be configured to receive water supply from the humidifying tank 36, and the humidifying system also includes a steam fan that boiles water by electric heat from a heater or the like and discharges the steam by the blower means 7. Applicable to formulas, ultrasonic type that makes water fine particles by ultrasonic waves and releases humidified air, vaporized filter containing water by blower means 3 and vaporized type that releases humidified air through nonwoven fabric Is possible.

  Here, the humidifying means 6 of the present embodiment will be described as a vaporizing type. As shown in FIG. 12, a visible light responsive photocatalyst is provided inside the air purifier body 6 as a moisture absorbing means for absorbing the water in the humidifying tank 36. A vaporization filter 37 that has been processed and an illumination mechanism 38 that can irradiate the vaporization filter 37 with visible light are provided.

  In the air cleaner body 6, air is passed from the air inlet (not shown) of the air cleaner body 6 through the blower 10 and the vaporization filter 37 to the discharge port 8 at the top of the air cleaner body 6. A path (not shown) is formed. The air blowing means 3 takes air into the air purifier main body 6 from the air inlet and sends it out to the vaporizing filter 37. The air for humidification is absorbed by the vaporizing filter 37 by applying air to the vaporizing filter 37. By evaporating, humidified air is sent out from the discharge port 8 to the outside of the air cleaner body 6. Although not shown here, a heating device such as a heater may be provided between the blowing unit 3 and the vaporizing filter 37 in order to send the air taken in by the blowing unit 3 as warm air to the vaporizing filter 37.

  Here, the illumination mechanism 38 is provided between the blowing means 3 of the ventilation path in the air cleaner body 6 and the vaporization filter 37 so that the vaporization filter 37 can be directly and indirectly irradiated with visible light.

First, the humidifying water is put into the humidifying tank 36, and the humidifying tank 36 is installed in the air cleaner body 6. Thereby, the humidifying water in the humidification tank 36 is guided to the vaporization filter 37. The vaporization filter 37 sucks up the humidifying water. After the humidifying water is absorbed by the vaporizing filter 37 in this way, when the operation switch (not shown) of the operation means 2 is turned on, the air blowing means 3 is activated and air is introduced into the air purifier main body 6 from the intake port. It is captured. Then, when wind hits the vaporizing filter 37, the humidifying water absorbed by the vaporizing filter 37 is vaporized and sent out from the discharge port 8 to the outside of the air purifier body 6 as humidified air.

  In the air cleaner, when the operation switch of the operation means 2 is turned on, the illumination mechanism 38 starts to emit light and irradiates the vaporizing filter 37 with visible light. As a result, the visible light responsive photocatalyst applied to the vaporization filter 37 undergoes a photocatalytic reaction, and the dirt due to the organic matter accumulated in the vaporization filter 37 is decomposed into water and carbon dioxide gas. In this way, the deposit itself of the vaporization filter 37 is decomposed by a visible light responsive photocatalytic reaction, so that the moisture absorption capability of the vaporization filter 37 may be reduced over a long period of time, and mold and bacteria may grow and generate odor. This can be prevented.

  In the present embodiment, the visible light responsive photocatalytic treatment is performed on the vaporization filter 37, so that germs generated on the vaporization filter 37 can be decomposed by visible light such as indoor lighting. The number of times can be reduced. In addition, since the vaporization filter 37 is always decomposed by visible light by visible light, it is possible to realize a longer life of the vaporization filter 37.

  Further, by providing the air purifier main body 6 with the illumination mechanism 38, it is possible to irradiate the vaporization filter 37 that has been subjected to the visible light responsive photocatalyst treatment more efficiently than the interior illumination, and thus vaporization is possible. It is possible to further enhance the sterilizing effect on the filter 37.

  In addition, about the vaporization filter 37 and the illumination mechanism 38 of a present Example, it can apply also to the humidifier provided with the ventilation means 3, the humidification means 33, and the humidification tank 36 similarly to the air cleaner of a present Example. Further, the present invention can be applied to an air purifier or a humidifier in which the dehumidifying tank 35 and the humidifying tank 36 are shared and only one tank is provided.

As described above, the present embodiment includes the vaporization filter 37 as the vaporization means, the humidifying tank 36 as the water supply means for supplying water to the vaporization filter 37, and the blower means 3 for sending air to the vaporization filter 37. An illumination mechanism 38 capable of irradiating the vaporizing filter 37 with a visible light responsive photocatalytic treatment is provided.

  In this case, by performing visible light responsive photocatalytic treatment on the vaporization filter 37, it is possible to sterilize germs generated on the vaporization filter 37 with visible light. Further, by providing the illumination mechanism 38, the vaporization filter 37 subjected to the visible light responsive photocatalytic treatment can be sterilized efficiently. Furthermore, since the antibacterial agent is not directly attached to the vaporization filter 37, it is possible to extend the life compared to the vaporization filter of a conventional air cleaner or humidifier.

  Next, the operation of the above configuration will be described. When the air purifier of the present embodiment purifies indoor air, the indoor air sucked into the air purifier main body 6 from the air intake window 39 is guided to the sensor substrate 40, and these room temperature sensor 30 and humidity sensor. 31 and gas sensor 44 detect the temperature, humidity and odor intensity (contamination level) in the room air. Here, the gas sensor 44 combusts air taken into the air cleaner body 6 by a built-in heater (not shown) to detect dirt in the air, and the control means 1 detects from the gas sensor 44. Based on the results, the presence or absence of odors and their respective amounts are estimated, and if the control means 1 estimates that the odor is strong, the rotational speed of the blower means 3 is increased to increase the amount of air blown into the room. Thus, in the air cleaner, a large amount of dust can be quickly collected by the filter device (not shown), and more room air can be purified in a short time. On the other hand, when it is estimated by the control means 1 that the odor is weak, the rotation speed of the fan of the blower means 3 is reduced by the control means 1 to reduce the amount of discharged air. In this way, in this embodiment, the amount of clean air blown out is adjusted according to the degree of indoor air pollution, so that it is possible to control the amount of exhaust air to the optimum according to the change in the degree of indoor air pollution. Can be removed quickly and reliably.

As described above, in this embodiment , the air provided with the sensor substrate 40 in which the gas sensor 44 attached adjacent to the same sensor substrate 40 and the room temperature sensor 30 as the temperature sensor are connected by the conductive pattern 48 as a pattern. A meandering portion 49 was formed in the conductive pattern 48 as a cleaner.

  In this case, since the heat released from the heater (not shown) of the gas sensor 44 is cooled by the meandering portion 49, the heat generated by the gas sensor 44 can be prevented from being transmitted to the room temperature sensor 30.

  FIG. 17 shows a fourth embodiment of the present invention. Common portions with the first to third embodiments are denoted by common reference numerals, and description of common portions is omitted as much as possible to avoid duplication.

  In the present embodiment, as shown in FIG. 17, on the back surface 45 of the sensor substrate 40, the gas sensor 44 and the room temperature sensor 30 include a gas sensor-connector conductive pattern 55 that connects the gas sensor 44 and the connector 47, and a room temperature sensor. 30 and the room temperature sensor-connector conductive pattern 56 for connecting the connector 47 are electrically connected by connecting them on the connector 47 side. Thus, the gas sensor 44 and the room temperature sensor 30 are connected by the conductive patterns 55 and 56 that pass through the connector 47. Reference numeral 57 in the figure is a conductive pattern for connecting the humidity sensor 31 and the connector 47.

As described above, in this embodiment , the gas sensor 44 attached adjacent to the same sensor substrate 40 and the room temperature sensor 30 as a temperature sensor are a gas sensor-connector conductive pattern 55 and a room temperature sensor as a conductive pattern as a pattern. An air purifier having a sensor substrate 40 connected by a connector-to-connector conductive pattern 56, wherein the gas sensor-connector conductive pattern 55 and the room temperature sensor-connector conductive pattern 56 are connected to the gas sensor 44 and the room temperature sensor 30; Is formed via a connector 47 which is another place.

  In this case, since the heat released from the heater (not shown) of the gas sensor 44 is cooled by the gas sensor-connector conductive pattern 55, the heat generated by the gas sensor 44 can be prevented from being transmitted to the room temperature sensor 30. . Further, even if the space between the room temperature sensor 30 and the gas sensor 44 is small and the meandering portion for cooling the heat cannot be formed in the conductive patterns 55 and 56 connecting the room temperature sensor 30 and the gas sensor 44, the room temperature sensor 30 However, it is possible to prevent the gas sensor 44 from being affected by heat.

  In addition, this invention is not limited to said each Example, A various deformation | transformation implementation is possible. For example, in this embodiment, the electrostatic atomizer 6 including the counter electrode 18 is described. However, the counter electrode 18 is not always necessary, and it is only necessary to apply a high voltage to the discharge electrode 17 with respect to the ground potential. For example, electrostatic atomization is performed. The material, shape and configuration of the discharge electrode 17 and the method for supplying water to the discharge electrode 17 can be changed as appropriate.
