As shown in fig. 8, the flange 710 is formed by a first arc-shaped surface 711 and a second mutual surface rising from the inner side of the air passage wall 701. In the present embodiment, the cambered surface curvature radius R1 of the inner side of the air duct wall 701, the curvature radius R2 of the first arc-shaped surface 711, and the curvature radius R3 of the second arc-shaped surface 712 satisfy the following constraint conditions: r1 is more than 95mm and less than 105 mm; r2 is more than 2mm and less than 4 mm; 18mm < R3 < 22 mm. And R1, R2 and R3 satisfy the following relationships: 4 × (R2+ R3) < R1.
through a plurality of tests of the inventor, the rotating speed of the cross-flow fan 200 is in the range of 600r/min to 1000r/min, and when the shape of the flange 710 meets the conditions, the coanda effect can be generated. The Coanda Effect (Coanda Effect), also known as Coanda Effect or Coanda Effect, refers to the tendency of a fluid (water or gas stream) to flow along a convex object surface instead of moving away from the original direction of flow. When there is surface friction (also called fluid viscosity) between the fluid and the surface of the object over which it flows, the fluid follows the surface of the object as long as the curvature is not large. Therefore, the flange 710 at the air outlet 113 can change the flow direction of the outlet airflow, that is, the outlet airflow flows along the flange 710 and is not directly blown onto the air conditioner decorative plate, thereby effectively avoiding the problem of condensation on the air conditioner decorative plate.
