In this embodiment, the bottom case 12 has a semicircular slot corresponding to the first side of the cover 40, and correspondingly, the first side of the cover 40 is semicircular, and the first side of the cover 40 extends into the semicircular slot of the bottom case 12, so as to be pivotally connected with the bottom case 12. Through the above arrangement, it can be ensured that the cover plate 40 will not be broken at the matching position of the first side and the bottom shell 12 during operation, and uneven air outlet is avoided.

As shown in fig. 1 to 5, the upper surface of the cover plate 40 is a second air guiding surface 41. In the present embodiment, the second air guiding surface 41 is a plane. Of course, the second air guiding surface 41 may be an arc surface sequentially connected with the air duct 20, and may be selected according to actual requirements.

In the present embodiment, the second side of the cover 40 is overlapped at the bottom edge of the air outlet 11 and is located at the initial position, and after the anti-condensation structure acts, the second side of the cover 40 is separated from the bottom edge of the air outlet 11 and forms a predetermined distance with the bottom edge of the air outlet 11, so that the cover 40 is located at the anti-condensation position. Specifically, as shown in fig. 4, when the cover 40 is at the initial position, the horizontal line a is the position where the air blown by the air conditioner can reach the air deflector 31; when the cover plate 40 is in the anti-condensation position, the horizontal line b is a position where the wind blown out by the air conditioner can reach the wind deflector 31. It can be seen that after the cover plate 40 rotates from the initial position to the anti-condensation position, under the action of the second air guiding surface 41, the air blown by the air conditioner can reach the position further away from the air guiding plate 31, so as to increase the air receiving area of the air guiding plate 31 and avoid condensation on the air guiding plate 31 in the place where the air cannot be blown.

Specifically, the plurality of grooves 431 are plural, and the plurality of grooves 431 are disposed at intervals along the extending direction of the air guiding rib 43.

In the present embodiment, since the width of the grooves 431 is too large to cause uneven air outlet as a whole, the call sound is easily generated, and too small to have an effect of diverting the air, the range of the width L3 of each groove 431 in the extending direction of the air guide rib 43 is set to 1mm to 3mm.

In the present embodiment, a guide structure is provided on an inner surface of a side wall of the housing 10, and at least a portion of the cover 40 is connected to the guide structure so that the cover 40 can move in a guide direction of the guide structure.
