In particular, since the suction grille 15a also serves as a means for guiding the upper surfaces on both sides of the filter 4, the portion has an L-shaped cross section composed of the bottom surface 10a and the side surface 10b. The auxiliary guide means may be formed, and may not be formed as the guide means 10 having a U-shaped cross section.

  For example, when the auxiliary guide means is formed in a U-shaped cross section, the suction grill 15a is overlapped on the upper surface of the U-shaped cross section, but is formed in an L-shaped cross section. Thus, as an indoor unit of an air conditioner, the structure can be reduced by about 3 millimeters corresponding to the thickness of the upper surface portion, the height dimension can be reduced, and the weight can be reduced. It becomes the structure which can reduce the usage-amount of the raw material (synthetic resin) equivalent to the thickness of an upper surface part.

  The suction grill 15a can have sufficient strength without forming the auxiliary guide means in a U-shaped cross section and overlapping the upper surface of the U-shaped cross section. There is no risk of insufficient strength.

  As described above, according to the present configuration, the cleaning device 5 is attached along the suction port 2 provided on the front surface and the upper surface of the front frame 1g forming the frame 1. The filter 4 can be moved back and forth to be cleaned, and when the heat exchanger 9 is maintained or removed, the front frame 1g having the moving path 6 having the above-described configuration can be easily removed forward. The brush drive motor 5b and the filter drive unit 18 attached to the front frame 1g can be easily maintained, and the front side of the front heat exchanger 7 can be opened largely. It becomes an air conditioner.
