Thus, when the room temperature is uneven, the air guide angle of the air conditioner is adjusted to the direction of high temperature reduction and low temperature increase, thereby improving the uniformity of the room temperature.
Based on the hardware architecture of the air conditioner, the embodiment of the control method of the air conditioner is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a control method of an air conditioner according to the present invention, the control method of the air conditioner including the steps of:
s10, adjusting the angle of an air deflector of the air conditioner for multiple times according to a preset direction;
the preset direction includes at least one direction from left to right, from right to left, from top to bottom, and from bottom to top. The air conditioner is provided with an upper air deflector and a lower air deflector, namely a horizontal swing blade, and/or a left air deflector and a right air deflector, namely a vertical swing blade. For example, the left and right air deflectors of the air conditioner are controlled to be turned to the leftmost side, and the air guiding angle is adjusted for multiple times in the left-to-right direction until the air guiding angle is adjusted from the leftmost side to the rightmost side.
Optionally, acquiring the temperature of each indoor air supply area; and a temperature sensor is correspondingly arranged in each air supply area and used for detecting the temperature value of each air supply area. The temperature sensors can be infrared temperature sensors arranged at different air outlets of the air conditioner and used for detecting the temperatures of different air supply areas, and can also be arranged at different positions in a room at intervals.
After the air conditioner is started to operate (including cooling operation and heating operation) for a preset time, if at least one of the absolute values of the temperature difference between the temperatures of the air supply areas is greater than the first preset temperature difference, executing the step of adjusting the angle of the air deflector of the air conditioner for multiple times according to the preset direction.
The first preset temperature difference may be 2 degrees celsius. Optionally, if there are more than two air supply areas, that is, there are more than two temperature sensors, when an absolute value of a temperature difference between a highest temperature and a lowest temperature among the temperatures detected by the temperature sensors is greater than a first degree celsius, the step of adjusting the angle of the air deflector of the air conditioner multiple times in the preset direction is performed.
It should be noted that, because different areas in a room are different from a heat source, for example, the temperature of a window is high, which causes uneven temperature in different areas in the room, or the air conditioner is operated in a cooling or heating mode to achieve rapid cooling or heating of the room temperature, the outlet air temperature during cooling is low, and the outlet air temperature during heating is high, and if the air deflector is operated at the maximum air deflection angle, which causes a large difference between the room area temperature right opposite to the air deflection angle and the area temperature not aligned to the air deflection angle, the temperature in different areas in the room is uneven, which affects comfort. Therefore, at least two temperature sensors can be arranged in different areas in the room for detecting the temperatures of the different areas in the room and adjusting the air guide angle of the air conditioner, so that the room temperature is more uniform.
If at least one of the absolute values of the temperature differences between the temperatures detected by the temperature sensors is greater than the first preset temperature difference, the absolute value of the temperature difference of the area where the at least two temperature sensors are located is greater, that is, the temperature in the room is not uniform, and therefore, the angle of the air deflector needs to be adjusted to make the room temperature more uniform.
S20, obtaining temperature values of all air supply areas after the angle of the air deflector is adjusted each time;
after the angle of the air deflector is adjusted each time, the temperature value detected by the temperature sensor corresponding to each air supply area needs to be acquired, so that the air guide angle which enables the room temperature to be more uniform is determined.
In order to enable the temperature detected by each temperature sensor to be more accurate after the air guide angle is adjusted each time, optionally, the operation time of the air conditioner is obtained after the air guide plate angle is adjusted each time;
and when the operation time length is equal to a first preset time length, acquiring the temperature value of each air supply area after the angle of the air deflector is adjusted each time. The time interval for adjusting the angle of the air deflector each time is greater than or equal to a first preset time.
The first preset time period may be 5 minutes, that is, the temperature detected by each temperature sensor is obtained after the air guide angle is adjusted for 5 minutes each time.
S30, determining a target angle according to a corresponding air guide angle when the temperature value of each air supply area meets a preset condition, wherein the preset condition comprises that the higher temperature of the temperature values of the air supply areas is reduced and the lower temperature of the temperature values of the air supply areas is increased;
alternatively, if the number of the air blowing areas exceeds two, that is, if the number of the temperature sensors exceeds two, the corresponding air guide angle is the target angle when the highest temperature among the temperatures detected by the respective temperature sensors decreases and the lowest temperature increases.
Referring to fig. 6, fig. 6 is a schematic diagram illustrating an arrangement of two temperature sensors according to an embodiment of the present invention, in which the air conditioner 21 is disposed on a wall, and the temperature sensors 22 and 23 are respectively spaced at different areas in a room. Referring to table 1, table 1 shows temperature variation trends detected by the temperature sensors corresponding to the air supply areas, i.e., the air supply areas, before and after the adjustment of the different air guide angles for a first preset time period. In one embodiment, two temperature sensors are arranged at intervals, wherein the temperature detected by the temperature sensor 22 is 22 ℃ before the wind guide angle α 1 is adjusted, the temperature detected by the temperature sensor 23 is 21 ℃, the temperature detected by the temperature sensor 22 is 23 ℃ after the wind guide angle α 1 is adjusted and the temperature detected by the temperature sensor 23 is 22 ℃ after the wind guide angle α 1 is operated for a first preset time; the temperature detected by the temperature sensor 22 is 23 ℃ before the air guide angle alpha 2 is adjusted, the temperature detected by the temperature sensor 23 is 22 ℃, the temperature detected by the temperature sensor 22 is 22 ℃ after the air guide angle alpha 2 is adjusted and the temperature detected by the temperature sensor 23 is 23 ℃ after the air guide angle alpha 2 is operated for a first preset time; before the wind plate angle alpha 3 is adjusted, the temperature detected by the temperature sensor 22 is 22 ℃, the temperature detected by the temperature sensor 23 is 23 ℃, after the wind plate angle alpha 3 is adjusted and the operation is carried out for the first preset time, the temperature detected by the temperature sensor 22 is 21 ℃, and the temperature detected by the temperature sensor 23 is 24 ℃.
That is, before and after the adjustment of the air guide angle α 1, the trend of the temperature change detected by the temperature sensor 22 is an increase, and the trend of the temperature change detected by the temperature sensor 23 is an increase, that is, a high temperature is an increase, and a low temperature is also an increase. Before and after the air guide angle α 2 is adjusted, the trend of the temperature change detected by the temperature sensor 22 is decreasing, and the trend of the temperature change detected by the temperature sensor 23 is increasing, that is, a higher temperature is decreasing, and a lower temperature is increasing. Before and after the adjustment of the air guide angle α 3, the trend of the temperature change detected by the temperature sensor 22 is a decrease, and the trend of the temperature change detected by the temperature sensor 23 is an increase, that is, a higher temperature is an increase, and a lower temperature is a decrease.
Therefore, the wind guide angle α 2 can be set as the target angle.

In the technical scheme provided by the embodiment, the air conditioner adjusts the angle of the air deflector for multiple times according to the preset direction; acquiring temperature values of all air supply areas after the angle of the air deflector is adjusted each time; taking a corresponding wind guide angle as a target angle when the higher temperature of the temperature values of the air supply areas is reduced and the lower temperature of the temperature values of the air supply areas is increased; and controlling the air deflector to adjust to the target angle. Thus, when the room temperature is uneven, the air guide angle of the air conditioner is adjusted to the direction of high temperature reduction and low temperature rise, thereby improving the uniformity of the indoor temperature.

Wherein the air conditioner 21 is arranged close to a wall in a room, and the temperature sensor 22, the temperature sensor 23 and the temperature sensor 24 are arranged at intervals in different areas in the room.
Referring to table 2, table 2 shows the temperature variation trend detected by each temperature sensor before and after the adjustment of different wind guide angles and after the operation for the first preset time period after the adjustment. In one embodiment, three temperature sensors are arranged at intervals in the environment where the air conditioner is located, wherein the temperature detected by the temperature sensor 22 is 22 ℃, the temperature detected by the temperature sensor 23 is 21 ℃, the temperature detected by the temperature sensor 24 is 22 ℃ before the air guiding angle α 1 is adjusted, the temperature detected by the temperature sensor 22 is 23 ℃, the temperature detected by the temperature sensor 23 is 20 ℃, and the temperature detected by the temperature sensor 24 is 21 ℃ after the air guiding angle α 1 is adjusted and the air guiding operation is carried out for a first preset time period; before the air guide angle alpha 2 is adjusted, the temperature detected by the temperature sensor 22 is 23 ℃, the temperature detected by the temperature sensor 23 is 22 ℃, the temperature detected by the temperature sensor 24 is 21 ℃, after the air guide angle alpha 2 is adjusted and the air guide device is operated for a first preset time, the temperature detected by the temperature sensor 22 is 22 ℃, the temperature detected by the temperature sensor 23 is 23 ℃ and the temperature detected by the temperature sensor 24 is 22 ℃; before the adjustment to the air guiding plate angle alpha 3 is carried out, the temperature detected by the temperature sensor 22 is 22 ℃, the temperature detected by the temperature sensor 23 is 23 ℃, the temperature detected by the temperature sensor 24 is 22 ℃, the temperature detected by the temperature sensor 22 is 23 ℃, the temperature detected by the temperature sensor 23 is 21 ℃ and the temperature detected by the temperature sensor 24 is 23 ℃ after the operation is carried out for the first preset time after the adjustment to the air guiding plate angle alpha 3 is carried out.
That is, before and after the air guide angle α 1 is adjusted, the temperature change trend detected by the temperature sensor 22 is an increase, the temperature change trend detected by the temperature sensor 23 is a decrease, and the temperature change trend detected by the temperature sensor 24 is a decrease, that is, the highest temperature is an increase or a decrease, and the lowest temperature is also a decrease. Before and after the air guide angle α 2 is adjusted, the temperature change trend detected by the temperature sensor 22 is decreased, and the temperature change trend detected by the temperature sensor 24 is increased, that is, the highest temperature is decreased, and the lowest temperature is increased.

And step S33, when the corresponding air guide angle is single when the temperature value of each air supply area satisfies a preset condition, taking the air guide angle satisfying the preset condition as the target angle.
Referring to table 1, when the corresponding air guide angle is only α 2 when the temperature value of each air supply area satisfies the preset condition, the air guide angle α 2 is taken as the target angle.
In the technical solution provided in this embodiment, when a plurality of target angles corresponding to a high temperature decrease and a low temperature increase in the temperature values of the air supply areas are provided, an absolute value of a temperature difference of the temperature of each air supply area when the preset condition is satisfied is obtained; and taking the wind guide angle with the minimum absolute value of the temperature difference as the target angle.

Referring to fig. 4, fig. 4 is a third embodiment of the control method of the air conditioner according to the present invention, and based on the first or second embodiment, after the step S40, the method further includes:
s50, when the operation time of the air deflector at the target angle is longer than or equal to a second preset time, acquiring the absolute value of the temperature difference between the temperature values of the air supply areas;

And S60, when the absolute value of at least one temperature difference is larger than a first preset temperature difference, returning to the step of adjusting the angle of the air deflector of the air conditioner for multiple times according to the preset direction.
The first predetermined temperature difference may be 2 ℃.

and when the return air temperature does not reach the set temperature, executing the step of acquiring the change value of the return air temperature of the air conditioner in the preset time interval.
It is understood that the set temperature may be a temperature set by a user in the air conditioner, and if the temperature in summer is high or the room is large or the capacity of the air conditioner is insufficient, so that the indoor ambient temperature is not reached to the set temperature, the change value of the return air temperature of the air conditioner in a preset time interval may be determined, and when the change value is less than or equal to the preset change value, the indoor ambient temperature is determined to be stable.
And when the return air temperature reaches a set temperature, executing the step of acquiring the temperature of each indoor air supply area.
When the return air temperature reaches the temperature set by the user, the current indoor environment temperature is stable, so that the temperatures of all temperature sensors in different areas in a room can be acquired, and the step of acquiring the temperatures detected by all the indoor temperature sensors is executed, so that the variation trend of the temperatures of all air supply areas corresponding to all the air guide angles and the absolute value of the temperature difference between the temperatures are acquired.
Optionally, controlling the air deflector to operate at the maximum air outlet angle when the air conditioner operates in a preset operation mode;
and after the air deflector runs for a preset time interval at the maximum air outlet angle, executing the step of acquiring the return air temperature of the air conditioner.
The preset operation mode includes a cooling mode or a heating mode. And when the air conditioner return air temperature acquired in the refrigeration mode is less than or equal to the set temperature, executing the step of acquiring the temperature of each indoor air supply area. And in the heating mode, when the acquired return air temperature of the air conditioner is greater than or equal to the set temperature, executing the step of acquiring the temperature of each indoor air supply area.
In the technical scheme provided by the embodiment, the change value of the return air temperature of the air conditioner in a preset time interval is obtained; and when the change value is smaller than a preset change value, executing the step of acquiring the temperature of each indoor air supply area. Therefore, the temperature values of the temperature sensors can be obtained when the air conditioner operates to the stable return air temperature, and the accuracy of obtaining the temperature values of the temperature sensors is improved.
