Referring to fig. 2, 3 and 4, an air guiding assembly 100 according to an embodiment of the present invention includes an air guiding plate 110, the air guiding plate 110 is used for guiding air, and the air guiding plate 110 is configured in an arc shape or a planar shape, which may be specifically selected according to an outer shape of a housing 200 or a structure of an air outlet frame 300, and is not limited in detail herein.

Referring to fig. 3 and 4, the wind guiding assembly 100 of the present embodiment further includes a rotating base 120, the rotating base 120 is connected to the wind guiding plate 110, one or more rotating bases 120 may be provided, the rotating base 120 is integrally connected to the wind outlet frame 300, or detachably connected to the wind outlet frame 300, the rotating base 120 has a rotating axis 121, the rotating axis 121 is a rotating shaft of the rotating base 120, and the wind guiding assembly 100 rotates around the rotating axis 121.

Referring to fig. 3 and 4, the wind guide assembly 100 of the present embodiment further includes a weight 130, the weight 130 is connected to the wind guide plate 110, and may also be connected to the rotary base 120, and the weight 130 and the wind guide plate 110 are respectively located at two sides of the rotation axis 121 in the circumferential direction. It will be appreciated that the plane formed by the geometric center of the weight member 130 and the rotational axis 121 substantially coincides with the plane formed by the geometric center of the air deflection plate 110 and the rotational axis 121. It should be noted that, in the embodiments of the present invention, the term "substantially coinciding" may be interpreted as coinciding, nearly coinciding, or having a predetermined angle.

It will be appreciated that when the weight member 130 and the air deflection plate 110 are of uniform density, the geometric center of the weight member 130 coincides with its center of gravity and the geometric center of the air deflection plate 110 coincides with its center of gravity. Referring to fig. 5, the gravity center of the wind guide assembly 100 is at the position G, and the moment arm from the wind guide assembly 100 to the rotation axis 121 is L. The motor needs to overcome the gravity F of the air deflector 110 to drive the air deflector 110 to rotate, and the required torque is N ═ F × L. Therefore, to reduce the output torque of the motor, it is necessary to reduce the gravity F of the air deflector 110 or the moment arm L of the air deflector assembly 100. The gravity center of the air deflector 110 is at the position of G2, the moment arm from the gravity center of the air deflector 110 to the rotation axis 121 is L2, the gravity center of the counterweight 130 is at the position of G1, the moment arm from the gravity center of the counterweight 130 to the rotation axis 121 is L1, and the gravity center G1 of the counterweight 130 and the gravity center G2 of the air deflector 110 are respectively positioned at the left end and the right end of the rotation axis 121 (O in FIG. 5).

Therefore, the gravity center G2 of the air deflector 110 and the gravity center G1 of the weight 130 are adjusted to make the moment generated by the gravity of the weight 130 offset the moment generated by the gravity of the air deflector 110, and of course, the moment generated by the gravity of the weight 130 may be greater than, less than or equal to the moment generated by the gravity of the air deflector 110, and is not limited in detail herein.
