In the technical scheme, the air outlet assembly comprises a first air deflector, a second air deflector and an air dispersing assembly. The first air deflector is arranged in the air outlet and can rotate along an axis perpendicular to the air outlet, so that the air supply angle of the air outlet is changed, and left air supply or right air supply is realized. The second air deflector is rotatably connected to the shell of the air conditioner and used for opening or closing the air outlet, specifically, when the air conditioner is turned off, the second air deflector covers the air outlet, and after the air conditioner is turned on, the second air deflector rotates relative to the air conditioner shell and opens the air outlet. Meanwhile, the second air deflector is provided with a plurality of through holes, and airflow can be scattered into a plurality of strands of small staggered airflow after passing through the through holes. When the wind-dispersing component is not started in the no-wind-sense mode, the wind-dispersing component is contained in the air conditioner. When the no-wind-sense mode is started, the wind dispersing component extends out and shields the wind outlet. The air dispersing assembly is also provided with an air dispersing structure, and the air flow passing through the air dispersing assembly can be dispersed through the air dispersing structure and is enabled to diffuse and flow, so that no wind feeling and direct blowing prevention are realized.

Specifically, the wind dispersing structure includes: the wind wheels are in meshing transmission through a gear structure, wherein each wind wheel comprises an inner rib and an outer ring rib, a first fan blade and a second fan blade are arranged between the inner ribs and the outer ring ribs, the first fan blade is a static fan blade, the first fan blade is fixedly connected with the inner ribs and the outer ring ribs, the second fan blade is a movable fan blade, the second fan blade is rotatably connected with the inner ribs, and the second fan blade is provided with a first position and a second position; the second fan blades are arranged at the first position, are arranged at intervals with the first fan blades, are arranged at the second position, and at least part of the second fan blades are overlapped with the first fan blades in the axial direction of the wind wheel. When the second fan blade rotates to the first position, the second fan blade and the first fan blade are arranged at intervals, and at the moment, the fan blades of the wind wheel are distributed densely, so that the airflow velocity passing through the wind wheel is low, and the effect of no wind feeling is strong. The second fan blade is located at the second position, the fan blades of the second fan blade and the fan blades of the first fan blade are superposed in the axial direction of the wind wheel, and at the moment, the fan blades of the wind wheel are distributed sparsely, so that the airflow velocity passing through the wind wheel is relatively high, the no-wind-feeling effect is weak, and the air supply capacity is strong.

Specifically, when the air outlet assembly is controlled to be switched from the first form to the second form, the position of the air diffusing assembly is maintained unchanged, the first air deflector is controlled to rotate from the first angle to the second angle, at the moment, the first air deflector still guides the air outlet of the air outlet to the air diffusing assembly, and after the first air deflector is adjusted to the second angle, the range covered by the air outlet direction is specifically the range corresponding to the first preset distance. And meanwhile, the second fan blade is controlled to move to a second position so as to improve the air quantity supplied to the first preset distance range and improve the refrigerating or heating effect.

The controlling means control air-out subassembly is switched to the third form by first form, specifically includes: controlling the first air deflector to rotate from a first angle to a third angle; the first air deflector rotates to a first angle or a second angle, and guides the air blown out from the air outlet to the air dispersing component; the first air deflector rotates to a third angle, and the first air deflector guides the air blown out from the air outlet to the second air deflector. Specifically, when the air outlet assembly is controlled to be switched from the first form to the third form, the first air deflector is controlled to rotate from the first angle to the third angle, and after the first air deflector rotates to the third angle, the first air deflector guides the air outlet direction of the air outlet to the first air deflector, namely, the air is exhausted through the through hole formed in the first air deflector. Meanwhile, the wind dispersing component keeps the strongest non-wind effect, and ensures that the human body in the range corresponding to the first distance cannot be directly blown.
