Therefore, in addition to the normal forward blowing, it is possible to blow left and right by closing the vertical wind direction plate. For this reason, the damper for switching the blower outlet from the front to the left and right is also used as the up-and-down wind direction plate, and the structure can be made simple and inexpensive. Of course, you may provide the blower outlet 30 only in the left or right side surface of a main body.

  As shown in FIG. 1 (A), this air conditioner forms a main body with a base 1 that is open on the front side and a front panel 2 that is mounted on the open front surface of the base 1. The front inlet 11 is provided on the upper surface, the upper inlet 12 is provided on the upper surface, and the outlet 3 is provided on the lower front. In the air passage connecting the front suction port 11 and the upper suction port 12 and the air outlet 3, a vertical portion 6 a, a rear inclined heat exchanger 6 b bent at the upper end of the vertical portion 6 a and inclined rearward, The heat exchanger 6 is composed of a downwardly inclined heat exchanger 6c bent at the upper end of the backward inclined heat exchanger 6b and inclined downward, and the air exchanged by the heat exchanger 6 is sent into the room. And a blower fan 7 composed of a cross flow fan is provided.

  The blower outlet 3 is provided with a plurality of left and right wind direction plates 5 and an upper and lower wind direction plate 4, which deflects the left and right direction of the air sent into the room by the left and right wind direction plates 5, and the upper and lower wind direction plates 4. Thus, the vertical direction is deflected.

  Further, the plurality of left and right wind direction plates 5 arranged in parallel at equal intervals constitute a left and right wind direction plate group 8 independent to the left and right when the air conditioner is viewed from the front. Motors 9 for independently deflecting left and right are arranged below the rear guider 10, respectively.

  On the other hand, on the inner surface of the up-and-down airflow direction plate 4 located in front of the air outlet 3, a plurality of ribs 4 a are provided standing toward the inside of the air conditioner and provided with a rotation shaft 4 b.
