DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an explanatory diagram of a substantially central cross section of an air conditioner showing an embodiment of the present invention.

FIG. 1 shows an indoor unit 1 of an air conditioner.
It is connected to an outdoor unit (not shown) by piping between units to form an air conditioner.

The case of the indoor unit 1 includes a front case portion 2A on the front side, a suction panel 2B provided with a room air intake port provided in front of the front case portion 2A, and a rear side rear portion. And a case 2C.

Reference numeral 4 denotes a heat exchanger for heating / cooling / dehumidifying the indoor air.
It functions as a cooler during the cooling / dehumidifying operation, and functions as a heater during the heating operation.

Reference numeral 5 denotes a blower fan for sucking room air from the suction panel 3, heating / cooling / dehumidifying the heat in the heat exchanger 4, and circulating the air again in the room, and 6 stores and discharges drain water from the heat exchanger 4. Drain pan 7 for the blower fan 5
The air filter 8 according to the embodiment of the present invention, which removes relatively large dust of indoor air sucked by the air filter, is an air cleaning filter that further removes relatively fine dust of indoor air that has passed through the air filter 7. is there.

Reference numeral 9 denotes an outlet for the cool air / hot air accelerated by the blower fan 5 and blown back into the room. Reference numeral 9A denotes an upper and lower portion which is attached to the outlet 9 and controls the direction of the cool air / hot air blown from the outlet 9. The wind direction deflecting blade 9B is also a left and right wind direction deflecting blade.

FIG. 2 is an explanatory perspective view of an air conditioner showing an embodiment of the present invention.

As shown in FIG. 2, an air filter 7 provided on the front surface of the indoor unit 1 has a pair of annular belts 11 which move up and down in parallel between the suction panel 2B and the heat exchanger 4.
And a pair of locking pieces 11B attached to specific positions facing each other on the respective belts 11, and an outer frame holding a pair of engaging portions 10B and the air filter 7 spanning the respective locking pieces 11B. Filter holding unit 10 comprising unit 10A
An air filter including a guide portion 12 for guiding a pair of engagement portions 10B so that the filter holding portion 10 moves in parallel with the front surface of the heat exchanger 4, and a driving portion 13 for driving a pair of belts 11. The attachment / detachment mechanism 20 enables the attachment / detachment.

By moving the pair of belts 11 on the left and right end sides of the heat exchanger 4, the lifting / lowering attachment / detachment mechanism 20 for the air filter 7 can be smoothly operated.

The above-mentioned driving unit is composed of a pair of left and right belts 11.
Is driven by a motor (for example, a DC stepping motor) capable of rotating forward and reverse, and the left and right belts 11 can be driven at a very low speed in conjunction with each other.

The belt 11 is preferably a cogged belt as shown in FIG. 2 in order to prevent the position of the left and right locking pieces 11B from shifting due to slippage with the drive unit 13.

Here, attachment and detachment of the air filter 7 will be described.

The driving unit 1 is operated by a user operating a remote controller.
3 operates slowly, rotates a pair of belts 11,
Along with this, the filter holding section 10B is engaged with the locking piece 11B of the belt 11 and the engaging section 10B of the filter holding section 10.
Descends along the guide portion 12, and the air filter 7 reaches below the indoor unit 1 and stops.

Here, the user bends the air filter 7 fitted in the grooves 10AA provided on the upper and lower portions of the filter holding portion 10 by holding both ends of the air filter 7 by utilizing the elasticity of the air filter 7. Thereby, the upper and lower grooves 10AA and 10AB are sequentially removed and detached.

When the air filter 7 is taken out, dust adheres to the air filter 7, so that there is an inconvenience that if the vibration or impact is applied, the adhering dust will fly up into the room. As described above, smooth detachment can be performed, so that such inconvenience can be prevented.

As shown in FIG. 2, in the present embodiment, two air filters 7 are arranged on the left and right sides, and the size of the air filters 7 is made reasonable to facilitate the user's attaching and detaching work.

The air filter 7 is formed by integrally molding the support frame 7A and the filter net 7B with the same resin, so that the filter 7A and the filter net 7B are different parts as in the case where the conventional support frame 7A and the filter net 7B are separate parts. There is no molding failure such as loosening or protrusion of the net 7B, and even when the dirty air filter 7 is cleaned, the loosening of the filter net 7B hardly occurs.

With the above-described structure of the elevating / removing mechanism 20 for the air filter 7, the amount of descent of the air filter 7 can be increased, and even if the indoor unit 1 is installed on the indoor wall near the ceiling, Without the need for safety,
Further, the air filter 7 can be easily attached / detached / cleaned.

The present invention is not limited to the above-described embodiment, but can be variously modified without departing from the gist of the present invention.
