In order to solve the problem that the compressed air effect of air outlet on an air conditioner is poor in the prior art, the application provides an air guide mechanism, the air conditioner and a control method of the air guide mechanism.

As shown in fig. 1 to 17, the air guide mechanism is provided at the outlet 10 of the air conditioner, and includes a plurality of air deflectors 20 and a plurality of driving devices 30. The plurality of air deflectors 20 are arranged at intervals along a preset direction, the plurality of air deflectors 20 comprise a first air deflector 21 and a second air deflector 22, and the second air deflector 22 is located on the rear side of the first air deflector 21. The plurality of driving devices 30 are disposed corresponding to the plurality of air deflectors 20 one by one, and each driving device 30 drives the corresponding air deflector 20 to rotate, so as to adjust the air outlet direction of the air outlet 10. The preset direction and the height direction of the air conditioner are arranged at a preset included angle, and at least part of the second air deflector 22 is arranged opposite to the first air deflector 21 along the height direction of the air conditioner.

By applying the technical solution of the present embodiment, the plurality of air deflectors 20 are arranged at intervals along the preset direction, the plurality of driving devices 30 are arranged in one-to-one correspondence with the plurality of air deflectors 20, and each driving device 30 drives the corresponding air deflector 20 to rotate, so as to adjust the air outlet direction of the air outlet 10. The plurality of air deflectors 20 include a first air deflector 21 and a second air deflector 22, the second air deflector 22 is located at the rear side of the first air deflector 21, and at least a part of the second air deflector 22 is arranged opposite to the first air deflector 21 along the height direction of the air conditioner. Like this, the in-process of air-out goes on at the air conditioner, and user accessible drive arrangement 30 controls the angle of opening of each aviation baffle 20, and then control the air-out direction to reach different pressure wind, air-out effect, and then solved the relatively poor problem of pressure wind effect of air-out on the air conditioner among the prior art, promoted the pressure wind effect of air-out on the air conditioner, promoted user's use experience.

In the present embodiment, each air deflector 20 is driven by an independent driving device 30, and the sweeping angle can be separately controlled, thereby achieving an optimal air blowing state.

In the embodiment, there are two air deflectors 20, two driving devices 30, and the two driving devices 30 and the two air deflectors 20 are disposed in a one-to-one correspondence manner, so that a user can adjust the air outlet direction and the air pressure height of each air deflector 20 according to the requirement.

Meanwhile, the number of parts of the air guide mechanism is reduced due to the arrangement, the assembly mode is simpler, and the air guide mechanism is easy to process and realize, so that the processing cost of the air guide mechanism is reduced.

when the air outlet needs to be closed, the opening angle of each air deflector is obtained, if the opening angles of the air deflectors are different, all the air deflectors are controlled to rotate until the opening angles are consistent, and then all the air deflectors are controlled to rotate synchronously until the air outlet is closed.
