The part of the inner side wall of each auxiliary air passage a, which is bounded by the front weft 1, forms the guide wall 112. It directs the air from the front air outlet 111 to the side air outlet 21. It is understandable that an air deflector is mounted on the front air outlet 111 of the indoor unit 1000. If the air baffle is open, the wind produced by the indoor unit 1000 is mainly supplied from the front air outlet 111, and rarely through the side air outlet 21 after passing through the passage a from auxiliary air. If the air baffle is closed, the wind produced by the indoor unit 1000 flows to the front air outlet 111, and then largely passes along the auxiliary air passage a to the side air outlet 21 (the arrow one direction indicates the direction of airflow in Figure 5).

It is known that the guide wall 112 can deflect the wind. In this way, the guide wall 112 can increase the volume of air flowing into the side air outlet 21 to a certain extent, thus resulting in the increase of the air outlet of the side air outlet 21.
