In some embodiments of the present invention, as shown in fig. 4, in the closed position, the surface of the drainage plate 3 away from the third air outlet 14 (for example, the upper surface of the drainage plate 3 at this position) is a curved surface, and thus, when the air current flows through the drainage plate 3, a coanda effect can be generated, where the coanda effect means that the fluid (water flow or air flow) has a deviation from the original flowing direction, and the fluid (water flow or air flow) tends to flow along with the convex object surface, and when there is surface friction between the fluid and the object surface through which the fluid flows (fluid viscosity can also be said), as long as the curvature is not large, the fluid will flow along the object surface, so that the surface of the drainage plate 3 away from the third air outlet 14 can have a better guiding effect on the flowing air current, and the structure is simple and is convenient to implement.

In practical application, the specific shape of the curved surface is not limited, and can be flexibly selected according to actual requirements, processing difficulty and the like. For example, in the closed position, the surface of the flow-guiding plate 3 facing away from the third air outlet 14 is a curved surface, in particular, the curved surface is convex in the direction away from the third air outlet 14, so that the structure is simple and the air flow can be better guided to the first air outlet 12.

In some embodiments of the present invention, as shown in fig. 4, the inner bottom wall of the airflow channel 21 is a curved surface extending along the front-back direction, and the curvature radius of the projection at the air outlet end 212 of the inner bottom wall of the airflow channel 21 and the curvature radius of the projection at the junction of the air outlet end 212 and the surface of the flow guide plate 3 deviating from the third air outlet 14 are the same in the plane perpendicular to the rotation center line of the flow guide plate 3.

Specifically, for example, referring to fig. 4, in a plane perpendicular to the rotation center line of the flow guide plate 3, i.e., a vertical plane, the projected shape of the inner bottom wall of the air flow channel 21 is a first curve 22, the projected shape of the surface of the flow guide plate 3 facing away from the third air outlet 14 is a second curve 34, and the radius of curvature of the first curve 22 at the air outlet end 212 is the same as the radius of curvature of the second curve 34 at the first end 31, so that the first curve 22 and the second curve 34 together define a smooth curve, and thus, in the closed position, the air flow can smoothly flow from the air outlet end 212 of the air flow channel 21 to the flow guide plate 3.
