Based on the control device 100 of the air conditioner, the invention further provides a control method of the air conditioner, and fig. 3 is a flow chart of the control method of the air conditioner according to an embodiment of the invention. As illustrated with reference to fig. 3, the method may comprise at least the following steps:
s302: the temperatures of the indoor unit 200 of the air conditioner detected by the movable temperature detecting device 300 at a plurality of preset locations of the room are acquired.

In the invention, the temperature of the room where the indoor unit 200 of the air conditioner is located can be obtained by the movable temperature detection device 300, and the obtained temperature is high in precision. The method calculates the average temperature and the temperature variance according to the temperatures of the preset positions, then judges whether the average temperature reaches a preset heat exchange threshold value, controls the air conditioner to start a heat exchange mode if the average temperature reaches the preset heat exchange threshold value, further determines the air supply mode of the indoor unit 200 of the air conditioner to the preset positions according to the temperature variance, and controls the indoor unit 200 to operate according to the corresponding air supply mode, so that the temperature of the room where the indoor unit 200 is located is uniform, and the temperature meets the requirement of the comfort level of a human body.
In some embodiments of the present invention, the obtaining of the temperatures detected by the movable temperature detecting device 300 in the plurality of preset positions of the room in which the indoor unit 200 of the air conditioner is located in the above step S302 specifically includes: constructing a two-dimensional coordinate system in a room where an indoor unit 200 of the air conditioner is located; planning a driving route comprising a plurality of preset positions in a two-dimensional coordinate system; the method comprises the steps of controlling the movable temperature detection device 300 to run along a running route and detect the position of the movable temperature detection device 300, and controlling the movable temperature detection device 300 to detect and acquire the temperature when the movable temperature detection device 300 runs to any preset position, so that the temperatures of a plurality of preset positions can be acquired.
The starting point to the end point of the traveling route may correspond to all air supply positions of the left and right flaps of the indoor unit 200. Specifically, the left and right flaps may have a plurality of air supply positions from one side to the other side of the indoor unit 200, and the plurality of air supply positions correspond to the plurality of air supply regions, respectively.

Wherein, the temperature variance is higher than the preset variance threshold value, which indicates that the temperature in the room is relatively uneven. In this case, when the air conditioner is in the cooling mode, the air supply mode of the indoor unit 200 is determined to be directional air supply to the preset position with the highest temperature among the plurality of preset positions, so that the average temperature and the temperature variance of the room can be reduced as soon as possible, and the comfort experience of the human body is improved; for the air conditioner in the heating mode, the air supply mode of the indoor unit 200 is determined to be directional air supply to the preset position with the lowest temperature in the plurality of preset positions, so that the average temperature and the temperature variance can be improved as soon as possible, and the comfort experience of the human body is improved.

In this case, the average temperature may be increased or decreased, and thus, the indoor unit 200 may be controlled to sequentially and directionally supply air to a plurality of predetermined positions regardless of the cooling mode or the heating mode of the air conditioner, so that the average temperature may be increased or decreased as quickly as possible.
Under the condition that the average temperature reaches the preset heat exchange threshold and the temperature variance is higher than the preset variance threshold, after the indoor unit is controlled to operate according to the corresponding mode, the movable temperature detection device 300 can be controlled to run back and forth along the above-mentioned running route until the average temperature is detected not to meet the preset heat exchange threshold and the temperature variance is detected to be smaller than the preset variance threshold.

And under the condition that the average temperature reaches the preset heat exchange threshold value and the temperature variance is lower than the preset variance threshold value, controlling the movable temperature detection device 300 to run back and forth along the running route in the same way until the average temperature is detected not to meet the preset heat exchange threshold value, and turning off the air conditioner.
In some embodiments of the present invention, for step S306 above, in case the average temperature does not reach the preset heat exchange threshold, it may be determined whether the temperature variance is higher than the preset variance threshold; if yes, the indoor unit 200 of the air conditioner is controlled to directionally supply air to the preset position with the highest temperature in the plurality of preset positions.
In this case, if the temperature variance is higher than the preset variance threshold, that is, the temperature in the room is relatively uneven, the indoor unit 200 is controlled to directionally supply air to the preset position with the highest temperature among the plurality of preset positions. So as to promote the air flow in the room and make the temperature in the room uniform.
And under the condition that the average temperature does not reach the preset heat exchange threshold value and the temperature variance is higher than the preset variance threshold value, controlling the movable temperature detection device 300 to run back and forth along the running route in the same way until the temperature variance is detected to be smaller than the preset variance threshold value, and turning off the air conditioner.
