An indoor unit of an air conditioner, comprising an air outlet duct (16) of a crossflow impeller (8) and an air outlet duct wall (15) of the cross flow impeller (8). An air drafting opening (13) is provided on the air outlet duct wall (15) of the crossflow impeller (8). The upper extremity (12) and the lower extremity (14) of the air drafting opening (13) are staggered to form the air drafting opening (13). In a projection plane perpendicular to the axis line of the crossflow impeller of the indoor unit and on which an air outlet of the indoor unit is located at the lower left side, the clockwise angle (131) between the line running from the upper extremity (12) to the lower extremity (14) of the air drafting opening (13) and the positive direction segment of a tangent to the air outlet duct wall (15) with the upper extremity (12) serving as the point of tangency is greater than or equal to 10° and less than or equal to 200°. |
