Thereby, a gap for guiding the filter 9 is provided between the front face member 52 and the rear face member 53.

  • the rib 15 is fixed to the filter net 13 so as to support the filter net 13. Thereby, the bending and waving of the filter 9 can be prevented.
  • the rib 15 is configured by a vertical rib 15a arranged in the vertical direction and a lateral rib 15b arranged in the lateral direction.
  • the vertical rib 15a is formed to have a small thickness, and the lateral rib 15b has a thickness larger than the thickness of the vertical rib 15a.
  • a slit 16 is provided between the lateral rib 15b and the vertical frame 14a of the filter frame 14, so that the lateral rib 15 and the vertical frame 14a are discontinuous from each other.
  • the vertical frame 14a and the lateral rib 15b are configured to be discontinuous from each other, the vertical frame 14a is hardly influenced by the lateral rib 15b, so that the bending property of the filter 9 in the vertical direction can be held.
  • any material only having flexibility can be used as the material of the filter frame 14, and hence any of polypropylene (PP), polyethylene terephthalate (PET), synthetic resin such as soft resin, rubber and paper may be used.
  • the filter net 13 for passing the air sucked from the suction port 6 is stretched in the upper portion of the filter 9.
  • a thin resin sheet 13a is stretched in the lower portion of the filter 9 instead of the filter net 13, so that the lower portion of the filter 9 is configured to prevent the passage of the air.
  • the resin sheet 13a is formed to have a small thickness similarly to the vertical rib 15a. Thereby, the bending property in the vertical direction is secured for the filter 9 as a whole.
  • the filter net 13 may be stretched on the whole surface of the filter 9.
  • the cleaning apparatus 12 is provided in the region 10b of the guide apparatus 10. Since the region 10b is formed in the linear shape, the filter 9 can be easily attached to the cleaning apparatus 12. Further, since the cleaning apparatus 12 is provided on the front side of the casing 4, the filter 9 can be easily attached to the cleaning apparatus 12.
  • the cleaning apparatus 12 is configured by an upper case 37 and a lower case 38 which have a substantially U-shaped cross section, and is fixed to the casing 4 so as to laterally bridge the front of the casing 4 in the state where the recessed sections of the upper case 37 and the lower case 38 are set to face each other.
  • a gap is between the upper case 37 and the lower case 38, so that the filter 9 can be moved through the gap.
  • a very narrow interval is maintained between the upper case 37 and the surface of the filter 9 and between the lower case 38 and the surface of the filter 9.
  • the left and right ends of a suction section 34 are opened. That is, it is configured such that the filter 9 can be made to pass through the cleaning apparatus 12 formed in the box shape as a whole.
  • the suction apparatus 35 is configured by a suction fan, and is connected to a duct (not shown) communicating the outside. A suction force is generated by rotating the suction fan, so that dust in the filter 9 can be sucked by the cleaning apparatus 12. The sucked air is exhausted to the outside from the duct.
  • the interval between the upper case 37 and the lower case 38 is set to be substantially equal to the width of the lateral ribs 15b of the filter 9.
  • the filter 9 when the filter 9 is cleaned, the filter 9 is moved forward by the rotation of the gear 32. At this time, the moving path A is formed by the guide apparatus 10 so as to be folded back into the U-shape in the front portion of the casing 4. Thereby, the front end of the filter 9 is guided backward (on the downstream side) while the filter 9 is bent according to the forward movement. As a result, the whole surface of the filter 9 can be cleaned.
  • the present invention can be effectively used for an air conditioner which is capable of blowing off conditioned air at the time of cooling and warming operation.
