Abstract

PROBLEM TO BE SOLVED: To provide an air conditioner in which dusts and odor components contained in sucked air can be sufficiently removed. SOLUTION: A cleaning unit 11 comprised of a dust-collecting segment 12 and a deodorizing segment 15 is installed between a rear inclined portion 8b and a front upper suction port 7 of a heat exchanger 8. The dust-collecting segment 12 is provided with an electric discharging wire 14 and a collector 13 for adsorbing dusts and powder dusts electrically charged with electric discharging from the electric discharging wire 14 so as to prevent a disadvantage that some fine powder dusts are laminated at a deodorizing member 17 installed in the deodorizing segment 15 to reduce a deodorizing function.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a sectional view showing an air conditioner according to the present invention, and FIGS. 2 and 3 are external perspective views showing a dust collecting section and a deodorizing section provided in a main body. As shown in FIG. 1, the air conditioner 1 according to the present invention includes a base 2 and a front panel 3 attached to the front of the base 2 to form a main body. A front upper suction port 7 is provided on an upper front face, an upper face suction port 6 is provided on an upper face, and an outlet 10 provided with a plurality of wind direction change plates 10a is provided on a lower part of the main body. A plurality of suction louvers 5a are rotatably supported on the support shaft portion of the main body at the front suction port 5, and a plurality of suction louvers 6a are similarly rotatably supported at the top suction port 6. Have been.

The front suction port 5 and the front upper suction port 7
In the air passage connecting the upper surface suction port 6 and the air outlet 10, a vertical portion 8a and a rear inclined portion 8b formed by bending the upper end of the vertical portion 8a and inclining rearward are provided. A heat exchanger 8 comprising a downwardly inclined portion 8c having an upper end bent and inclined downward, and a blower fan 9 for sending air exchanged by the heat exchanger 8 from the outlet 10 into the room. Is provided.

An air purifying unit having a dust collecting function and a deodorizing function is provided between the rear inclined portion 8b of the heat exchanger 8 and the front upper suction port 7. The first embodiment is an air cleaning unit 11 shown in the external perspective view of FIG.
As shown in the figure, the dust collection unit 1 is covered by a front cover 12a having a plurality of suction holes 12b on the front surface and a ventilation hole on the rear surface.
And a deodorizing section 15 formed behind the dust collecting section 12 and continuously formed with the front cover 12a, the front face being open and the rear cover 15a having a ventilation hole formed in the rear face. .

A filter (hereinafter referred to as a collector) 13 formed in a fin shape and having a function of adsorbing charged dust and dust is laid on the dust collecting portion 12, and the collector 13 is provided upright. A plurality of discharge electrode wires 14 are provided between the fin portions to discharge and charge dust and dust contained in the suction air. A deodorizing member 17 made of a resin material such as PTFE (polytetrafluoroethylene) and formed in a net shape for performing a photocatalytic reaction is mounted on the bottom surface of the deodorizing portion 15. An ultraviolet lamp 16 is provided. The ultraviolet lamp 16 intermittently irradiates ultraviolet rays toward the deodorizing member 17 to excite a photocatalytic reaction to decompose odor components adsorbed on the deodorizing member 17.

Next, the operation of the air cleaning unit 11 having the above configuration will be described. The suction air sucked from the front suction port 5 and the front upper suction port 7 is sucked into the dust collecting part 12 from the suction hole 12b formed in the front of the air cleaning unit 11. In the dust collecting section 12, electric discharge is performed from the discharge electrode wire 14 into the air, and the dust and dust contained in the suction air are combined with the discharged electric charges and charged, and the charged dust and dust are discharged. , Without being passed through the collector 13 which is charged to the opposite polarity, is absorbed by the collector 13 and removed from the suction air. Next, the suction air from which dust and dust have been removed flows into the deodorizing section 15, and the deodorizing member 17 mounted in the deodorizing section 15 adsorbs the odor component composed of fine particles and is cleaned. .

The suction air purified by the air cleaning unit 11 is heat-exchanged by the heat exchanger 8 to be cooled or warmed and sent out from the outlet 10 into the room. By removing the fine dust in the dust collecting section 12, the dust is stacked on the surface of the deodorizing member 17 mounted in the deodorizing section 15 and acts as an obstacle to smoothly absorb the odor component. It is possible to prevent such a phenomenon that the odor component is not smoothly decomposed due to the irradiation of the ultraviolet lamp and the deodorizing function is reduced, and the deodorizing member 17 made of a resin material is If it is periodically cleaned, it can be used repeatedly, and the cost can be reduced as compared with a deodorizing member made of paper.

Next, a second embodiment of the present invention will be described with reference to FIG. As shown in FIG. 3, the air cleaning unit 1
Reference numeral 8 denotes a configuration in which a dust collecting portion 19 and a deodorizing portion 20 are juxtaposed in a cover 18a having a plurality of suction holes 18b on the front surface and a ventilation hole on the rear surface. At the approximate center of the cover 18a, there are provided a plurality of discharge wires 14 together with a collector 13 formed in a fin shape, and a deodorizing member 21 made of a resin material formed in a curved shape on both sides thereof. An ultraviolet lamp 16 is provided so as to be held by the deodorizing member 21. The air purifying unit 18 is disposed on the front surface of the heat exchanger 8b similarly to the air purifying unit 11, and the suction air sucked from the front suction port 5 and the front upper suction port 7 is supplied from the suction hole 18b. Removal of dust sucked into the air cleaning unit 18 and deodorization are performed in parallel. The air in the room is repeatedly suctioned to gradually purify the air, and the air purifying unit 18 has a small thickness to reduce the thickness of the air conditioner body.
