  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a longitudinal sectional view of an air conditioner according to an embodiment of the present invention, and FIG. 2 is a perspective view illustrating an automatic filter cleaning function of the air conditioner.

  1 and 2, reference numeral 1 denotes an air conditioner main body according to the present invention, 2 denotes a suction port provided from the front surface to the upper surface of the main body 1, and 3 denotes an air outlet provided at a lower portion of the main body 1.

  A filter 4 that removes large dust in the air, a blower fan 5 linked to a fan motor 8, and a heat exchanger 6 are provided in an air passage that connects the suction port 2 and the blowout port 3. Yes.

  A deodorizing filter 113 is provided between the filter 4 and the heat exchanger 6, and a negative ion generator 114 is provided in the outlet 3.

  The filter 4 has a belt-like shape in the vertical direction and can move in the horizontal direction, and has a nozzle 115 having a suction port 118 and a brush 119 on the filter surface side. They are connected by a duct 117.

  The fins of the heat exchanger 6 are coated with a surface treatment agent mixed with the antibacterial and antifungal agent zinc pyrithione.

  By being formed as described above, the air conditioner according to the present invention operates as follows.

  First, the filter 4 that captures large dust and protects the internal heat exchanger 6 and the like will be described.

  When the dust discharge fan 116 is driven, the dust on the filter surface is sucked and cleaned from the suction port 118 of the nozzle 115, passes through the suction duct 117 and the dust discharge fan 116, and is discharged outdoors. Furthermore, as the nozzle 115 moves to the left and right, the entire surface of the filter 4 is cleaned, and the brush 119 is more reliably and completely cleaned.

  Needless to say, maintenance is not necessary for the filter 4 due to the above-described operation. Furthermore, since the surface is always kept in a state where there is almost no dust, generation of mold usually generated in the dust is not caused. No airflow resistance is maintained because there is no airflow resistance.

  Next, the operation of the negative ion generator 114 as an electric dust collector will be described. The electric dust collector is a dust collecting means for minute dust such as cigarette smoke and pollen.

  A general electrostatic precipitator consists of a charging unit and a dust collecting unit. The charging unit charges the dust and makes it easy to attach to the dust collecting unit for efficient dust collection. If dirt accumulates due to adhesion of fine particles, maintenance such as cleaning and washing becomes necessary.

  In this embodiment, the negative ion generator 114 applies a high potential to the electrode 114 </ b> A, which corresponds to a charging unit that charges dust in the air, but the negative ion generator 114 is used for the filter 4 and the heat exchanger 6. There is no need for cleaning because it is downstream, does not contain large dust in the passing air, and minute dust is removed by the filter 4 by its own charge and dust collecting action as described later.

  Further, the filter 4 functions as a dust collecting unit for adhering charged dust, but the filter 4 is automatically cleaned as described above.

  The above operation eliminates the need for maintenance on the electric dust collector, which is a dust collecting means for minute dust.

  Next, operations of the negative ion generator as negative ion generation means, sterilization means, and allergen removal means will be described.

  In the present embodiment, the negative ion generator 114 is also an ion generating means for generating negative ions. In addition, it is recognized that the negative ions generated by the negative ion generator 114 are released into the room on the blowout air of the air conditioner, thereby eliminating the sterilizing effect of the room air and removing the allergen.

  As described above, since the negative ion generator 114 does not need to be cleaned, maintenance is not required for the negative ion generator, the sterilizer, and the allergen remover.

  Next, the deodorizing filter 113 which is a deodorizing means will be described.

  The deodorizing filter 113 of the present embodiment is composed of an adsorbent having a physical adsorption action, an oxide containing cobalt and having a catalytic action, and a carrier formed in a filter shape carrying the adsorbent and the oxide. ing.

  In such a deodorizing filter 113, the oxide converts acetaldehyde, which is an odorous component in room air, into acetic acid, and then adsorbs the acetic acid with the adsorbent and removes it from the air. Thereafter, when air having a small odor component passes through the deodorization filter 113, the adsorbed acetic acid is decomposed and desorbed, so that the adsorbent is not saturated with the odor component.

  By the way, the situation where the function of the deodorizing filter 113 deteriorates is that the filter-like carrier is clogged with dust, minute dust, etc., and ventilation is hindered, or the part that physically adsorbs is buried, The adsorbing part may be saturated.

  In this embodiment, the former can be prevented by the filter 4 and the electrostatic dust collecting function, and the latter is decomposed and desorbed by ventilation, so that the adsorbent is not saturated with the odorous component.

  Further, in the present embodiment, since the air flow rate is not reduced particularly by the automatic cleaning function of the filter 4, the desorption is performed efficiently, and the performance deterioration of the deodorizing filter 113 is more effectively suppressed.

  The above operation eliminates the need for maintenance on the deodorizing filter 113 which is a deodorizing means.

  Next, the heat exchanger 6 according to the present embodiment will be described.

  A surface treatment agent mixed with the antibacterial and antifungal agent zinc pyrithione is applied to the fins of the heat exchanger 6 of this embodiment. When the fin surface gets wet during cooling, the antibacterial and antifungal agent zinc pyrithione elutes from inside the surface treatment agent and acts on the mold and fungi that grow on the dust and moisture attached to the fin surface, producing these fungi and fungi. Suppresses dirt and odors and keeps the fin surface clean. Furthermore, by exhibiting the antibacterial and antifungal effect also in the drain hose from the drain pan 7 where the condensed water in which the antibacterial and antifungal agent is dissolved flows, dirt and odor can be suppressed.

  Although detailed description is omitted, the duration of the antibacterial and antifungal effect can be adjusted by appropriately selecting the composition and amount of the antibacterial and antifungal agent and the surface treatment agent.

  Maintenance such as cleaning for the heat exchanger 6 is not necessary due to the above operation.

  As described above, the air conditioner according to the present invention is provided with a filter, a heat exchanger, and a blower fan in the air passage connecting the suction port and the air outlet, respectively, and removes and collects dust on the filter. And a dust removal means having a dust discharge fan unit, the filter or the dust collector or both move, the operating position of the dust collector relative to the filter moves relatively, and the entire surface of the filter is moved. It is configured to be cleanable, and decomposes and regenerates odorous components such as an adsorbent having a physical adsorption action on a filter-shaped carrier and a catalyst such as a metal oxide between the filter and the heat exchanger. It is equipped with a deodorizing filter carrying a component that has a function to operate, so that the user can use it without degrading the original function without paying attention to maintenance There, in addition to the indoor unit of an air conditioner, it can be widely applied to devices in general having a variety of filter group.
