Description

FIELD

The present disclosure relates to the technical field of an air conditioner, and more particularly, to a driving device for an air deflector of an air conditioner and an air conditioner.

BACKGROUND

At present, an air outlet of an air conditioner on the market is provided with an air deflector of the air conditioner. When the air conditioner is not working, the air deflector of the air conditioner will seal the air outlet, thus effectively preventing dust and water vapor from entering the air conditioner and also ensuring an aesthetic appearance of the air conditioner. When the air conditioner is in a working state, the air deflector of the air conditioner may adjust an air direction to avoid a direct blowing. That is, the air deflector of the air conditioner may change an air blowing direction to avoid blowing directly to a human body, so as to reduce adverse effects on a human health due to the direct blowing.
The air deflector of the existing air outlet of the air conditioner mounted on a wall is mostly an integral structure, and is driven by a motor to rotate and change the air blowing direction, which however has a limited effect on a degree of a change in the air direction. Therefore, the whole air deflector of the air conditioner is divided into two separate air deflectors, and the two air deflectors rotate simultaneously, which may better change the air blowing direction of the air outlet of the air conditioner. However, if two motors are selected to drive the two air deflectors, respectively, the cost and the power consumption are relatively high, which is not conducive to the protection of environment. Thus, it is necessary to propose a driving device for an air deflector of an air conditioner and an air conditioner, so as to at least partially solve the problems existing in the prior art.

In addition, the main plate 10-1 has a limitation to the second boss 10-3, and thus the degree of freedom of the second boss 10-3 translating left and right is limited, such that the second boss 10-3 may only rotate freely in the third round hole 9-1, thus completing the hinging of the second link plate 9 and the third link plate 10. Further, a sectional diameter of the third tapered head 10-3-1 away from the main plate 10-1 is smaller than a diameter of the second boss 10-3, the third U-shaped groove 10-3-1-1 is formed in the third tapered head 10-3-1, an opening of the third U-shaped groove 10-3-1-1 faces towards a side away from the main plate 10-1, a bottom of the third U-shaped groove 10-3-1-1 extends to an end of the second boss 10-3 adjacent to the third tapered head 10-3-1, and the third tapered head 10-3-1 deforms to have a smaller diameter while the third tapered head 10-3-1 is extending into or out of the third round hole 9-1, so as to facilitate the assembling and disassembling of the second link plate 9 and the third link plate 10.
