Ascending, the other end is fixed to the lower part of the fixing part 13D of the driving part 13.
[0037]
Here, the operation of the elevating / removing mechanism 20 when the air filter 7 and the air purifying filter 8 are attached / detached / cleaned will be described.
[0038]
The motor 13A of the drive unit 13 operates slowly by the operation of the user's remote controller, rotates the pair of pinions 13B of the drive unit 13, and the second filter holding unit 10A meshes with the second pin 10A via the rack 10AB and the second. The second filter holding portion 10A descends along the groove of the guide 12B of the guide portion 12 with which the engaging portion 10AD of the filter holding portion 10A is engaged.
[0039]
While the second filter holding unit 10A is lowered, the first filter holding unit 10B guided by the second filter holding unit 10A is guided by the belt 13E of the driving unit 13 and is connected to the second filter holding unit 10A. Descent to the bottom.
[0040]
As described above, the first filter holding portion 10B is lowered, and the air filter 7 is moved along the guide 12A of the guide portion 12 and the second filter holding portion 10A to the holding portion 10BC of the first filter holding portion 10B. Towed down.
[0041]
When the descent is completed, the user pulls the air filter 7 toward the front with the hole 7E at the center thereof to remove the latch 7D of the air filter 7 from the rib 10BD of the holding portion 10BC, and slowly moves the air filter toward the front. The air filter 7 can be detached and cleaned while pulling 7.
[0042]
Thereafter, the user removes / cleans the air cleaning filter 8 by removing the claw 10BT of the first filter holding portion 10B.
[0043]
Further, when the air filter 7 is taken out, dust adheres to the air filter 7, so that there is a disadvantage that the dust adhering to the room rises when vibration or impact is applied. Such a disadvantage can be prevented because smooth desorption can be performed.
[0044]
The air filter 7 and the air purifying filter 8 that have been cleaned can be attached to and stored in the air conditioner 1 by reversing the above-described operation.
[0045]
By making the lifting / removing mechanism 20 between the air filter 7 and the air purifying filter 8 as described above, the surface area of the air filter 7 and the amount of the air filter 7 can be increased and installed on the indoor wall near the ceiling. Even in the indoor unit 1, it is possible to remove and clean the air filter 7 safely and easily without requiring a step or the like.
[0046]
