(Embodiment 1)
FIG. 1 is a cross-sectional view of an air conditioner equipped with an air purification device according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view of the air purification device.

  1 and 2, a suction port 2a is arranged on the front surface of the air conditioner 2, and a filter 3 for collecting dust contained in air flowing from the suction port 2a is provided downstream of the suction port 2a. An air purification device 1 that deodorizes deposits such as indoor air and indoor wall surfaces is disposed on the downstream side of 3. 4 is a heat exchanger that performs heat exchange of air, and 48 is a cross-flow fan for passing air through the heat exchanger 4.

  A part of the air 34 sucked from the suction port 2a of the air conditioner 2 is purified by the filter 3 and then passes through the inside of the air purification device 1 to become dry air 6 to become the heat exchanger 4 and the cross It passes through the flow fan 48 and is discharged into the room from the outlet 2b. Further, the mist 8 generated by the electrostatic atomizing means 20 of the air cleaning device 1 spreads in the indoor space along the flow 7 from the outlet 2b of the air conditioner 1.

  Next, the structure of the air purification apparatus 1 is demonstrated using FIG.

  The air purification device 1 is composed of a porous material such as zeolite, and absorbs and releases moisture in the air, and also supports a moisture absorbing / releasing material layer 33 carrying a catalyst mainly composed of platinum (Pt), and the absorbing and absorbing material layer 33. Forced air blowing means 10 for sending air to the moisture-releasing material layer 33, heating means 11 for heating the air forcedly ventilated through the moisture-absorbing / releasing material layer 33, and heated air passing through the moisture-absorbing / releasing material layer 33 A heat radiation cooling layer 12 that performs heat radiation cooling, a first water storage unit 14 that stores water 30 that is condensed by heat radiation cooling, a moisture absorption cycle that absorbs moisture in the air to the moisture absorption / release material layer 33, and a moisture absorption / release material. A water generating means 15 comprising a control means (not shown) for alternately operating a moisture releasing cycle for desorbing moisture adsorbed on the moisture absorbing / releasing material layer 33 by feeding heated air into the layer 33; The water stored in the water storage unit 14 is carried to the second water storage unit 17. And a pair of electrodes provided in the second water storage unit 17, that is, a first electrode 31 and a second electrode 32 facing the first electrode 31, and the first electrode 31 is provided. And an electrostatic atomizing means 20 for generating mist 8 by atomizing the water in the second water storage section 17 by applying a high voltage between the first electrode 32 and the second electrode 32.

  About the air purification apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The air 34 sucked into the air purification device 1 by the forced air blowing means 10 is adsorbed by a porous moisture absorbing / releasing material layer 33 such as zeolite and discharged as dry air 6 (moisture absorption cycle). The amount of moisture adsorbed on the moisture absorbing / releasing material layer 33 varies depending on the air volume of the forced air blowing means 10 or the forced air blowing time. When the heating unit 11 is operated while the forced air blowing unit 10 is operated, the temperature of the air sent to the moisture absorbing / releasing material layer 33 is increased, and the temperature of the moisture absorbing / releasing material layer 33 is increased. When the temperature of the moisture absorbing / releasing material layer 33 such as zeolite rises, the adsorbed moisture is desorbed, and the air sent by the forced air blowing means 10 becomes humidified air, which is a heat radiation cooling layer composed of a heat sink, a heat pipe, or the like. 12 (moisture cycle). That is, when the humid air at a high temperature is cooled by the heat radiation cooling layer 12, the moisture in the air becomes saturated, and water droplets are generated in the heat radiation cooling layer 12.

  By repeating the moisture absorption cycle and the moisture release cycle, the water generated by the water generating means 15 is stored in the first water storage unit 14 and conveyed to the second water storage unit 17 through the communication path 16. At least one first electrode 31 having a sharp tip is disposed in the second water storage unit 17, and a high voltage is applied between the second water storage unit 17 and the second electrode 32 facing the first electrode 31. As a result, the mist 8 is generated by atomizing the water in the second water reservoir 17.

As described above, according to the present embodiment, it is possible to deodorize indoor air and deodorize deposits such as indoor wall surfaces by electrostatic atomization with no water supply.

  Further, in order to desorb moisture adsorbed on the moisture absorbing / releasing material layer 33, the surface temperature of the heating means 11 becomes a high temperature exceeding 100 ° C. Therefore, in the air passing near the surface of the high temperature heating means 11 It is possible to kill moths and viruses and at the same time oxidize odorous components and deodorize them.

  In addition, when air is sent to the forced air blowing means 10 that is made of a porous material such as zeolite and absorbs and releases moisture in the air, the moisture absorbing / releasing material layer 33 has air in the air. In addition to adsorbing moisture and odor components in the air, when heated air is fed by the heating means 11, the adsorbed water and odor components are desorbed, and the odor components are returned to the room through the air conditioner 2. However, the moisture absorbing / releasing material layer 33 carries a catalyst mainly composed of platinum (Pt), so that heated air is sent to the odor component in contact with the catalyst mainly composed of heated platinum (Pt). As a result, it is oxidatively decomposed by the action of the catalyst.

  Thereby, in addition to the deodorization of indoor air by electrostatic atomization and the deodorization of deposits such as indoor wall surfaces, the effect of deodorizing indoor air by catalytic reaction can also be obtained.

  Next, the configuration of the filter 3 will be described with reference to FIG.

  3 is a perspective view of the filter 3. The filter 3 includes a filter frame 40, an air filter 41, a movable suction nozzle 42, a suction hose 43 that is extendable and has one end connected to the suction nozzle 42, The suction exhaust device 44 to which the other end of the suction hose 43 is connected, the exhaust duct 45 having one end connected to the discharge side of the suction exhaust device 44 and the other end opened to the outside, and the suction nozzle 42 are moved left and right. The suction filter 42 has a driving means 46 and is periodically collected by a control device (not shown) so that the suction nozzle 42 is collected in the air filter 41 while moving to the right or left. The sucked dust is sucked and automatically discharged from the exhaust duct 45 to the outside. That is, the movable suction nozzle 42 and the suction / exhaust device 44 constitute automatic cleaning means for the air filter 41.

  As described above, since dust and dirt entangled with the air filter 41 are automatically cleaned periodically, the ventilation resistance of the air filter 41 is always kept low.

  Further, since the air purification device 1 is disposed on the downstream side of the filter 3, dust or dust mixed in the air flowing in from the suction port 2a does not enter the air purification device 1, and therefore the air purification device. There is no risk of ignition and smoke generation by the heating means 11 of the first water generating means 15, and the safety of the air conditioner 2 can be ensured. Furthermore, the air filter 41 can be prevented from being clogged with dust by the automatic cleaning function of the filter 3, and the air resistance of the air filter 41 is always kept low, so that a stable water generating ability can be exhibited.

  Further, as shown in FIG. 1, the water generation means 15 of the air purification device 1 is configured to be disposed above the water tray 47 that receives the condensed water of the heat exchanger 4.

  When the humidity is very high such as in summer, a large amount of water may be generated from the water in the air by the water generating means 15 and the water may overflow from the first water storage unit 14. Therefore, it is carried out with the drain water of the air conditioner 2 to the outside.

  Thereby, the water fall to the inside / outside of the air conditioner 2 can be prevented, and the safety of the charging unit (not shown) of the air conditioner 2 can be ensured and the occurrence of complaints from customers can be prevented.

  Further, as shown in FIG. 1, the electrostatic atomizing means 20 that atomizes the water in the second water storage unit 17 to generate mist is disposed in the outlet 2 b of the air conditioner 2.

  With the above configuration, even if a high voltage is applied between the first electrode 31 and the second electrode 32 and the water in the second water storage unit 17 is atomized to generate mist, heat exchange in the air conditioner 2 is performed. The mist collides with the air conditioner 4 and the cross flow fan 48, and the amount of mist diffused from the air outlet 2b of the air conditioner 2 is not drastically reduced, and the mist can be efficiently diffused from the air outlet 2b. .

  As a result, the charged mist exits from the outlet without being affected by the heat exchanger 4 or the crossflow fan 48 of the air conditioner 2, so that the indoor air can be effectively deodorized or the indoor wall surface can be attached. Kimono can be deodorized.
