s122a, determining the rotation direction and the rotation angle of the first inner wind guide wall according to the first distance difference, wherein the first distance difference is positively correlated with the rotation angle of the first inner wind guide wall;

s123a, when the first distance difference is larger than zero, controlling the first inner wind guide wall to rotate clockwise by a first angle; when the first distance difference is smaller than zero, the first inner wind guide wall is controlled to rotate a second angle anticlockwise; when the first distance difference is equal to zero, keeping the first inner wind guide wall stationary;

referring to fig. 7 and 8 and fig. 9, in the present embodiment, there are two movable air guiding walls, which are the first inner air guiding wall and the second inner air guiding wall, that is, the left inner air guiding wall and the right inner air guiding wall, respectively. Then, the detected space distances of the first inner wind guide wall and the second inner wind guide wall are correspondingly two, namely a first space distance and a second space distance. For ease of understanding, the present embodiment simulates an indoor space as one rectangular space. The first distance is L1 which is the farthest end of the left air outlet of the left air duct where the left air guide wall is located from the length direction of the rectangular space. The second distance is L2 which is the farthest end of the right air outlet of the right air duct where the right air guide wall is located from the width direction of the rectangular space. It will of course be appreciated that L1 may also be the width of the rectangular space and L2 may also be the length of the rectangular space. The air outlet distance of the air conditioner in the normal mode is L0, namely the preset space distance is L0. If the user selects the intelligent air-out mode, after L1 and L2 are detected, L1 is compared with L0.

When the indoor far-end distance L1 measured at the left air outlet is greater than the air supply distance L0 of the air conditioner in the normal mode, namely DeltaT=L1-L0, deltaT > 0, the left inner air guide wall rotates clockwise along the shaft by a first angle alpha 1 (alpha 1 and DeltaT are positively correlated and have alpha 1max value), namely in the far-wind mode.

When the indoor remote distance L1 measured at the left air outlet is smaller than the air supply distance L0 of the air conditioner in the normal mode, namely DeltaT=L1-L0, deltaT is smaller than 0, the left inner air guide wall rotates anticlockwise along the shaft by a second angle alpha 2 (alpha 2 and DeltaT are positively correlated, and have alpha 2max value), namely the soft air mode.

When the indoor remote distance L1 measured at the left air outlet is equal to the air supply distance L0 of the air conditioner in the normal mode, namely DeltaT=L1-L0, and DeltaT=0, the left inner air guide wall does not rotate along the edge, namely in the normal mode.

Referring to fig. 12, in an embodiment, the step S120 includes the steps of: S121A-S123A.

S121A, determining a second distance difference according to the second space distance and a preset space distance;

S122A, determining the rotation direction and the rotation angle of the second inner wind guide wall according to the second distance difference, wherein the second distance difference is positively correlated with the rotation angle of the second inner wind guide wall;

S123A, when the second distance difference is larger than zero, controlling the second inner wind guide wall to rotate anticlockwise by a third angle; when the second distance difference is smaller than zero, the second inner wind guide wall is controlled to rotate clockwise by a fourth angle; and when the second distance difference is equal to zero, keeping the second inner wind guide wall stationary.

With continued reference to fig. 7 and 8 and fig. 9, in the present embodiment, similarly, after L1 and L2 are detected, L2 is compared with L0.

When the indoor remote distance L2 measured at the air outlet on the right side is larger than the air supply distance L0 of the air conditioner in the normal mode, namely DeltaT=L2-L0, deltaT is more than 0, and the right inner air guide wall rotates anticlockwise along the shaft by a third angle beta 1 (beta 1 and DeltaT are positively correlated and have beta 1max value), namely a remote air mode;

when the indoor remote distance L2 measured at the air outlet on the right side is smaller than the air supply distance L0 of the air conditioner in the normal mode, namely DeltaT=L2-L0, deltaT is smaller than 0, the left inner air guide wall rotates clockwise along the shaft by a fourth angle beta 2 (beta 2 and DeltaT are positively correlated and have a beta 2max value), namely a soft air mode;

when the indoor remote distance L2 measured at the right air outlet is equal to the air supply distance L0 of the air conditioner in the normal mode, namely, Δt=l2-L0, and Δt=0, the left inner air guide wall does not rotate, namely, in the normal mode.

Referring to fig. 13, in an embodiment, the air outlet control method further includes the steps of: S130-S140.

S130, detecting the wind sweeping angle of the target wind deflector;

and S140, controlling the target movable air guide wall to rotate according to the target wind sweeping angle so that the target movable air guide wall rotates along with the target air guide plate.

In the embodiment, when the user adjusts the wind sweeping angle, the movable wind guide wall rotates along with the wind sweeping angle, so that the wind outlet direction is as consistent as possible with the wind guide plate direction, and the wind loss caused by direct impact of wind on the wind guide plate is reduced. Specifically, because the air deflectors are arranged in different air channels, firstly, which air deflector rotates is determined, the rotating air deflector is identified as a target air deflector, and then the wind sweeping angle of the target air deflector is detected, and the wind sweeping angle can be, for example, left wind sweeping, right wind sweeping, upper wind sweeping or lower wind sweeping. When the wind sweeping angle of the wind deflector is left wind sweeping, the movable wind deflector rotates clockwise, namely leftwards, so that the wind outlet direction is consistent with the wind guiding direction. Similarly, other wind sweeping angles have the same control logic, and are not described in detail herein. The movable air guide wall rotates along with the target air guide plate, so that the air outlet direction is consistent with the air guide plate direction, and the air quantity loss caused by the fact that air directly impacts on the air guide plate is reduced.

In other embodiments, the air conditioner may further be provided with a human sense function, and the side automatically adjusts to a soft air mode when it is detected that the user is located in the air outlet direction of the left or right air outlet for a long time.

While the invention has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
