BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail as examples based on the accompanying drawings. FIG. 1 is a sectional view showing an air conditioner according to the present invention, and FIG. 2 is a sectional view showing a state in which a photocatalytic filter is irradiated with light.
As shown in FIG. 1, the air conditioner according to the present invention is provided with a front suction port 1 at the front upper part, a top suction port 2 at the upper surface, and a blowout port 3 having a plurality of wind direction changing plates 3a at the lower front part. ing. A shaft provided at the lower end is pivotally supported on the front suction port 1, and front opening / closing louvers 1a, 1b and 1c for opening and closing the front suction port 1 by moving back and forth are provided up and down. The upper surface suction port 2 is also provided with front and rear upper surface opening / closing louvers 2a, 2b and 2c which are pivotally supported by a shaft provided at the rear end thereof and which are vertically moved to open and close the upper surface suction port 2.

The front suction port 1 and the upper suction port 2
And an air path connecting the air outlet 3 and the air outlet 3, the electrostatic precipitator 6
A heat transfer tube arranged in a meandering manner so as to be orthogonal to the fins, and performs heat exchange with the air sucked from the front suction port 1 and the upper suction port 2. A heat exchanger 4 for cooling or heating the same and a blower fan 5 for sending the air, which has been heat-exchanged by the heat exchanger 4, from the outlet 3 to the room are provided.

The heat exchanger 4 comprises a vertical portion 4a provided so as to face the front inlet 1, and a rear inclined portion 4b in which the upper end of the vertical portion 4a is bent and inclined rearward. Front heat exchanger and lower slope 4c with the rear end inclined downward
And a rear heat exchanger consisting of.

A photocatalytic filter 7 is detachably provided on the back surface of the front suction port 1. The photocatalyst filter 7 contains titanium oxide and is adapted to adsorb odorous components, bacteria and various bacteria contained in the air sucked from the front inlet 1, and the adsorbed odorous components, bacteria and various bacteria, etc. Is decomposed or sterilized when the photocatalytic filter 7 is irradiated with ultraviolet rays, and so-called reduction treatment is performed.

The front opening / closing louvers 1a, 1b and 1c provided on the front inlet 1 are provided with a mirror surface portion by a mirror surface treatment, and the light incident on the mirror surface portion is reflected to the photocatalytic filter. I am led to 7.

Next, the operation of the air conditioner having the above structure will be described. When the cooling operation or the heating operation is performed for a certain period of time, odorous components, bacteria, miscellaneous bacteria and the like are adsorbed and accumulated in the photocatalytic filter 7. To remove these, the operation is stopped first, and the front opening / closing louvers 1a, 1b are removed.
And 1c are respectively turned forward and opened to allow the light from the fluorescent lamp 21 installed in the room to pass through the photocatalyst filter 7
To be irradiated. At this time, light may be reflected on the mirror surface portions formed on the back surfaces of the front opening / closing louvers 1a, 1b, and 1c and irradiated on the surface of the photocatalytic filter 7.

When the photocatalytic filter 7 is irradiated with light from the fluorescent lamp 21 or sunlight, the catalytic reaction of the photocatalytic filter 7 is excited by the action of the ultraviolet rays contained therein, and the adsorbed odorous components or bacteria are decomposed. And, sterilization of various bacteria is performed within a certain level.

As described above, the photocatalyst filter 7 is removed from the front suction port by removing the odorous components or germs accumulated in the photocatalyst filter 7 to some extent by the light from the fluorescent lamp 21 installed in the room. It is possible to reduce the number and frequency of so-called sun-drying with sunlight by pulling it out from the back surface of No. 1 and improving the maintainability.

[0016]

As described above, according to the present invention,
The light emitted from the fluorescent lamp installed in the room is guided to the photocatalytic filter by opening the front opening / closing louver, and it can be decomposed within the range where odorous components are decomposed or bacteria and various bacteria are sterilized.
