Generally, the second air guiding plate is composed of a plurality of air guiding plates which are transversely arranged, and a first camera and a second camera are respectively mounted on two boundary air guiding plates of the second air guiding plate; wherein, first camera and second camera are the miniature camera head of wide narrow range: the camera lens is designed to be rectangular, rather than a conventional circle, so that the captured image is wide and narrow, resembling a "first-line-of-day" image. This is because it is desirable to detect the features of the top of the user's head (such as hair) and the user's neck in a narrow range as possible, as a determination condition for starting to enter the relevant control, for example, the second wind deflector is slowly deflected downward from the uppermost angle, and the second wind deflector is swept like a "thousand-layer cake" until the features of the top of the user's head are detected, and if the features are in a regular circle shape, a large area of portrait is shot, which is easily misjudged.

Each transversely arranged air deflector corresponds to the same second angle range, and two angle boundary values for limiting the second angle range are respectively a third angle boundary value and a fourth angle boundary value; when the third angle boundary value is an angle lower limit value, the fourth angle boundary value is an angle upper limit value; when the third angle boundary value is an angle upper limit value, the fourth angle boundary value is an angle lower limit value.

Controlling each transversely arranged air deflector to longitudinally rotate by a third preset unit angle or a fourth preset unit angle each time, preferably, the third preset unit angle is equal to the fourth preset unit angle; when each transversely-arranged air deflector rotates towards the third angle boundary value, the number of times of rotation of any transversely-arranged air deflector is recorded as the first longitudinal rotation number, the product of the first longitudinal rotation number and the third preset unit angle is calculated, and the current longitudinally-rotated angle of each transversely-arranged air deflector can be obtained when the third angle boundary value is taken as a reference point; when each transversely-arranged air deflector rotates towards the fourth angle boundary value, the number of times that any transversely-arranged air deflector rotates is recorded as the second longitudinal rotation number, the product of the second longitudinal rotation number and the fourth preset unit angle is calculated, and the current longitudinally-rotated angle of each transversely-arranged air deflector can be obtained when the fourth angle boundary value is used as the reference point.

The gravity center direction is taken as the lower direction, the reverse direction is taken as the upper direction, the third angle boundary value is the uppermost angle, the fourth angle boundary value is the lowermost angle, the first camera is installed on the lowermost air deflector in the plurality of transversely-arranged air deflectors, and the second camera is installed on the uppermost air deflector in the plurality of transversely-arranged air deflectors. When the transversely arranged air deflectors rotate from top to bottom, a first camera is used for detecting whether a user head exists or not, if the user head is detected, the rotating speed of the fan is reduced, after the transversely arranged air deflectors rotate downwards continuously, a second camera is used for detecting whether a user neck exists or not, if the user neck is detected, the rotating speed of the fan is recovered, and if the user neck is not detected, the transversely arranged air deflectors rotate downwards continuously until the user neck is detected by the second camera and/or the user neck rotates to the lowest position; if the head of the user is not detected, continuing to rotate downwards until the first camera detects the head of the user and/or rotates to the lowest part; when the transversely arranged air deflectors rotate from bottom to top, the second camera is firstly adopted to detect whether a user neck exists, if the user neck is detected, the rotating speed of the fan is reduced, the first camera is adopted to detect the head of the user after the transversely arranged air deflectors rotate upwards continuously, if the user head is detected, the rotating speed of the fan is recovered, and if the user head is not detected, the transversely arranged air deflectors rotate upwards continuously until the first camera detects the head of the user and/or rotates to the top; if the neck of the user is not detected, the second camera continues to rotate upwards until the second camera detects the neck of the user and/or rotates to the top.

In the second aviation baffle downwardly rotating in-process, the controller control first camera of air conditioner carries out detection work, when first camera does not detect user's head, the fan operates with normal rotational speed, when first camera detects user's head, the fan rotational speed descends according to user's position, in order to guarantee that cold wind can not blow user's head, continue downwardly rotating in-process, control second camera and carry out detection work, when the second camera detects user's neck, resume the fan to normal rotational speed operation. Correspondingly, at the second aviation baffle in-process that upwards rotates, the controller control second camera of air conditioner carries out detection achievement, when the second camera does not detect the user's neck, the fan operates with normal rotational speed, when the second camera detects the user's neck, the fan rotational speed descends according to the user's position, in order to guarantee that cold wind can not blow the user's head, continue the in-process that downwards rotates, control first camera and carry out detection achievement, when first camera detects the user's head, resume the fan to normal rotational speed operation.

When all the transversely arranged air deflectors longitudinally rotate to a fourth angle boundary value, clearing the first longitudinal rotation times; when all the transversely arranged air deflectors are not longitudinally rotated to the fourth angle boundary value, continuously controlling all the transversely arranged air deflectors to rotate towards the fourth angle boundary value by the third preset unit angle, adding 1 to the first longitudinal rotation frequency, and returning to execute the step C2; correspondingly, when all the transversely arranged air deflectors longitudinally rotate to a third angle boundary value, clearing the second longitudinal rotation times; and when the transversely arranged air deflectors do not longitudinally rotate to the third angle boundary value, continuously controlling the transversely arranged air deflectors to rotate towards the third angle boundary value by the fourth preset unit angle, adding 1 to the second longitudinal rotation frequency, and returning to execute the step D2.

In the process that the air deflectors longitudinally arranged at this time rotate from 0 to 180 degrees, the angle which is transversely rotated is 140 degrees, the angle range which is not transversely rotated is (140 degrees and 180 degrees), all distances which are associated with the angle range which is not transversely rotated are 0.8m and 1m, the minimum distance is 0.8m, the rotating speed of a fan which is associated with 0.8m can be obtained, and then the current rotating speed of the fan of the air conditioner is adjusted to the obtained rotating speed of the fan.

As shown in fig. 4, the air outlet of the air conditioner is provided with left and right air deflectors and upper and lower air deflectors. The wide and narrow area miniature camera 1 is tightly attached to the plane of the air deflector and is arranged at the middle position outside the lower plane of the lowermost upper air deflector and the lowermost lower air deflector, so that the camera, the upper air deflector and the lower air deflector synchronously rotate and have consistent directions; the wide and narrow miniature camera 2 is tightly attached to the plane of the air deflector and is arranged at the middle position outside the upper plane of the uppermost upper air deflector and the uppermost lower air deflector, so that the camera, the upper air deflector and the lower air deflector synchronously rotate and have the same direction; the two-in-one sensor 1 is tightly attached to the plane of the air guide plate and is arranged at the middle position of the outer side of the left air guide plate and the outer side of the right air guide plate at the leftmost side, so that the sensor and the left air guide plate and the right air guide plate synchronously rotate and have consistent directions; the two-in-one sensor 2 is tightly attached to the plane of the air guide plate and is arranged at the middle position of the outer side of the left air guide plate and the outer side of the right air guide plate on the rightmost side, so that the sensor, the left air guide plate and the right air guide plate synchronously rotate, and the directions are consistent.

If the leftward deflection angle is smaller than or equal to the maximum angle, the data detection and storage operations are circulated according to the unit angle value until the left air deflector and the right air deflector rotate to the left maximum angle.

After the operation is executed, the controller detects and stores the distance between the air outlet and personnel at each position in the room. Then the controller controls the upper air deflector and the lower air deflector (the wide and narrow area miniature camera 1) to rotate downwards from the maximum angle on the upper side, and the fan rotates at the conventional rotating speed; if the camera 1 does not recognize hair or head top characteristics through images, the upper air deflector and the lower air deflector continue to rotate downwards, and the fan rotates at a conventional rotating speed;
