The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and obviously, the described embodiments are a part of the embodiments of the present invention rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention
In the description of the present invention, it should be noted that the terms "installation", "connection" and "connection" should be understood broadly, for example, may be a fixed connection, may also be a detachable connection, or may be integrally connected, unless otherwise specified and defined. may be a mechanical connection or an electrical connection; The communication may be a direct connection or an indirect connection via an intermediate medium, or an internal connection of two elements, or a wireless connection or a wired connection. For a person of ordinary skill in the art, the specific meaning of the above terms in the present invention can be understood in particular.
An embodiment of the present invention provides a method for rotating an air guide plate to a preset position, where the method is applicable to Fig. 1, and may include the following steps:

S110. Acquire a first angle between the preset position and the first limiting position and a second angle between the preset position and the second limiting position. In particular embodiments, the first limiting position and the second limiting position are two limiting positions of the air guide plate rotating upward and downward. In this embodiment, the preset position may generally include a fixed upward air guiding position, a fixed downward air guiding position, and a reset position of the air guiding plate. Specifically, Fig. 2a shows the reset position of the air guiding plate, which may be a position before the air guiding plate is positioned after the air guiding is completed. Fig. 2b shows the position of the air guide plate when the wind is guided upward, in order to ensure that the comfort of the user can be guided upward in the wind guide direction during cooling, and Fig. 2c shows that the position of the air guide plate when the wind is guided downward is to ensure that the comfort of the user can be guided downward in the wind guide direction during heating. The preset position may be obtained according to the current working mode, so that the first angle and the second angle may be obtained.
S120. judge whether the first angle is less than the second angle. In particular embodiments, during the rotation of the air guide plate, due to a weight of the air guide plate and a gap between the gears driving the air guide plate to rotate, a virtual position of the air guide plate may be caused, the larger the rotation angle of the air guide plate, and the probability and the times of the virtual position of the air guide plate may be increased correspondingly. Especially when the air guide plate is rotated to a gravity center of the air guide plate near a vertical line of the rotating shaft, the probability of virtual position increases, it is necessary to select a path with a smaller angle from the limiting position to the preset position to rotation, and when the first angle is less than the second angle, the process proceeds to step S130; When the first angle is greater than the second angle, the process proceeds to step S140.
S130. Control the air guide plate rotates to the first limiting position. In particular embodiment, since the first angle is less than the second angle, a distance between the first limiting position and the preset position is less than a distance between the second limiting position and the preset position. After the air guide plate is rotated to the first limiting position, the distance to the preset position is smaller, the times or the probability of generating a virtual position is smaller, and the air guide plate may be more accurately roatated to the preset position. In this embodiment, the limiting position may be an upper limiting position, or may be a lower limiting position. Specifically, the limiting position is arranged opposite to the second limiting position.
S140. Control the air guide plate rotates to the second limiting position. Referring specifically to the description of controlling the rotation of the air guide plate to the first limiting position in step S130 described above.
S150. Control the reverse rotation of the air guide plate rotates to a preset position. In particular embodiments, after the air guide plate is rotated to the limiting position, the rotation angle of the air guide plate is reset to zero, based on the limiting position, that is, a limiting position is set to zero, and according to a angle between the preset position and the limiting position, the air guide plate is controlled to rotate the angle between the preset position and the limiting position in an opposite direction, so that the air guide plate is rotated to the preset position. In the present embodiment, due to the angle of the reverse rotation is generally small. In the process of rotating the air guide plate, the probability or of the times of virtual positions is small, so that the air guide plate can be controlled more accurately to a preset position.

After the air guide plate is rotated to the limiting position, during the reverse rotation of the air guide plate to the preset position, the virtual position may be generated, resulting in a rotation angle is inaccurate, as shown in Fig. 3, the method for rotating the air guide plate to the preset position may further include the following steps:

S210. Acquire a first angle between the preset position and the first limiting position and a second angle between the preset position and the second limiting position. For details, reference may be made to the description of obtaining the first angle and the second angle in step S110 of above embodiments.
S220. judge whether the first angle is less than the second angle. For details, reference may be made to the description of judging whether the first angle is less than the second angle in step S120 of above embodiments, and when the first angle is less than the second angle, the process proceeds to step S230; When the first angle is greater than the second angle, the process proceeds to step S240.
S230. Control the air guide plate rotates to the first limiting position. For details, reference may be made to the description of controlling the rotation of the air guide plate to the first position limiting position in step S130 of above embodiments.
S240 controls the air guide plate rotates to the second limiting position. For details, reference may be made to the description of controlling the rotation of the air guide plate to the second limiting position in step S140 of above embodiments.
S250. Compensate for the reverse rotation angle of the air guide plate. In particular embodiments, the air guide plate generates the virtual position during rotation, and may increase or decrease an angle of the air guide plate according to the rotation direction of the air guide plate. Specifically, when an upper limiting position is rotated reversely to the preset position, due to the gravity of the air guide plate, when the air guide plate is generated virtual position, the air guide plate is rotated by a certain angle in advance, and an angle can be reduced, so as to ensure that after a driving mechanism rotates by a compensated preset angle, the preset angle is reduced by a certain angle, so that the air guide plate can reach the preset position more accurately. When reverse rotating to the preset position based on a lower limiting position, due to the gravity of the air guide plate, the air guide plate returns a certain angle when the virtual position is generated, and an angle may be added to ensure that after the driving mechanism rotates through the compensated preset angle, the preset angle is increased by a certain angle, so that the air guide plate can reach the preset position more accurately.
S260 controls the reverse rotation of the air guide plate rotates to the preset position. For details, reference may be made to the description of controlling the reverse rotation of the air guide plate rotates to a preset position in step S150 in above embodiments.

In an optional embodiment, as shown in Fig. 4, step S250 may include:

S251. Acquire the angle of the reverse rotation of the air guide plate. In a specific embodiment, the angle of the reverse rotation may be obtained according to the angle between the position limiting position nearer to the preset position and the preset position. The magnitude of the angle of the reverse rotation may be determined after the operation mode of the air guide plate is determined.
S252. Obtain a compensation angle according to the angle of the reverse rotation. In a specific embodiment, since the virtual position is actually generated during the reverse rotation of the air guide plate, the larger the rotation angle is, the more the virtual position angle may be generated, in this embodiment, the compensation angle may be determined according to the magnitude of the angle of the reverse rotation, for example, The the angle of the reverse rotation may be compensated in a ratio of a certain the angle of the reverse rotation, for example, when the angle of the reverse rotation is 30°, 3° may be compensated, and when the angle of the reverse rotation is 60°, 6° may be compensated. The specific ratio may be determined according to the actual use condition.
S253. Compensate the angle of the reverse rotation of the air guide plate with the compensation angle. For a specific compensation method, reference may be made to the compensation for the angle of the reverse rotation in step S250.

Judging the magnitude of the included angle between the preset position and the two limiting positions of the air guide plate rotation, selecting a limiting position with a small included angle with the preset position, rotating the air guide plate to the limiting position, and performing reverse rotation on this basis, the angle of the reverse rotation is general small, and the probability of the position jump is very small, so that the rotation angle of the air guide plate can be precisely positioned. The comforts of the user using the air conditioner and the accuracy of the air guide plate when the air guide plate reset are improved.
In order to save the time for the air guide plate rotates to the preset position, in an optional embodiment, the method for rotating the air guide plate to the preset position may also compensate for the angle for the air guide plate to rotate, specifically, acquire the included angle between a current position the air guide plate and the preset position. The compensation angle is determined according to the magnitude of the included angle, and reference may be made to the method for determining the compensation angle in step S252 of above embodiments. Compensate the rotation angle from the current position of the air guide plate to the preset position with the compensation angle. Only the rotation angle from the current position of the air guide plate to the preset position is compensated, and the air guide plate does not need to be rotated firstly to the limiting position, and the angle is compensated in the process of rotating from the current position to the preset position, thereby saving the time of rotating to the preset position.
