  • Fig. 50 is a disassembly perspective view illustrating an air conditioner in accordance with a fourteenth embodiment of the present invention. The aforementioned members are not explained.
  • a retainer bridge 55 includes bridge panels 55B incorporated with a retainer plate 52, and bridge pins 55C inserted into bridge grooves 55D of the kit case 300.
  • Fig. 51 is a structure view illustrating an air conditioner in accordance with a fifteenth embodiment of the present invention.
  • the filter cleaners of the air conditioner include filter retainers 50 on the kit cases 300 to improve suction force. Therefore, dust of the left and right filters 31 and 32 can be efficiently sucked by using one suction force generation unit 320.
  • suction holes 350A and 350B coupled to the kit drain hoses 326 connected respectively to the left and right filters 31 and 32 are formed on the cyclone 350.
