step S10, obtaining the target adjusting direction of the air guide strip of the air conditioner;
the target adjusting direction is the direction corresponding to the air supply area to be adjusted in the thermal comfort degree in the environment where the air conditioner is located.
Optionally, the target adjustment direction may be preset according to a user requirement, or may be obtained by obtaining second thermal comfort values of different air supply areas of an environment where the air conditioner is located, determining the target thermal comfort values by comparing the second thermal comfort values of the air supply areas, and determining the target adjustment direction according to the air supply area corresponding to the target thermal comfort value, where the target thermal comfort value is a maximum value of the second thermal comfort values when the air conditioner operates in the cooling mode, and the target thermal comfort value is a minimum value of the second thermal comfort values when the air conditioner operates in the heating mode.
Step S20, adjusting the angle of the wind guide strip according to the target adjustment direction;

and adjusting the angle of the air guide strips according to the target adjustment direction, namely guiding the air blown out by the air conditioner to an air supply area corresponding to the target adjustment direction through the air guide strips, wherein the air supply area corresponding to the target adjustment direction can be understood as an air supply area with thermal comfort to be adjusted. Exemplarily, determining the target adjustment direction to be leftward based on the current air guide angle of the air guide strip of the air conditioner, and then adjusting the angle of the air guide strip leftward; for another example, if the target adjustment direction is determined to be upward based on the current wind guide angle of the wind guide strip of the air conditioner, the angle of the wind guide strip is adjusted upward.
It should be noted that the thermal comfort value, i.e. pmv (predicted Mean volume), is an internationally recognized index for describing the indoor thermal environment. The PMV index comprehensively considers different influence factors of human body thermal comfort and represents the evaluation of most people on the thermal comfort of the indoor environment, so that the index objectively reflects the thermal comfort of the indoor thermal environment. Wherein, the thermal comfort value is determined according to the air velocity value, namely the wind speed value, the humidity value, the temperature value, the radiation temperature, the dressing index and the human body metabolism index. In this embodiment, the radiation temperature, dressing index and body metabolism index parameters may be preset values or obtained from big data.
It should be noted that the wind speed value is determined according to the rotation speed of the indoor fan, the angle of the air guide strip, and the position of the sensor, and it is understood that the corresponding relationship between the rotation speed of the indoor fan, the air guide angle of the air guide strip, the position of the sensor, and the wind speed value may be preset and stored in the storage of the air conditioner.
For example, in calculating the thermal comfort value, to facilitate understanding of the determination of the wind speed value, based on the position of the air conditioner, the environment of the air conditioner is divided into two air supply areas, i.e., a left air supply area and a right air supply area, where the sensor a is disposed on the left side of the air conditioner and corresponds to the left air supply area, and the sensor B is disposed on the right side of the air conditioner and corresponds to the right air supply area.
The wind speed value is determined jointly according to the rotating speed of the indoor fan, the position of the sensor and the angle of the wind guide strip, specifically, a reference wind speed value of the wind speed value is determined according to the rotating speed of the indoor fan, a coefficient of the wind speed value is determined according to the angle of the wind guide strip and the position of the sensor, and the wind speed value is determined according to the reference wind speed value of the wind speed value and the coefficient of the wind speed value, for example, the wind speed value is determined by multiplying the reference wind speed value of the wind speed value and the coefficient of the wind speed value. The coefficient for determining the wind speed value through the angle of the wind guide strip is as follows:
1. when the angle of the air guide strip is the middle position, the coefficient of the wind speed value V is 1.0 when the thermal comfort values of the left air supply area and the right air supply area are calculated;
2. taking the angle of the air guide bar as a middle position as a reference position, adjusting the angle of the air guide plate to XL +1 leftwards, wherein the angle of the air guide bar is XL +1, and then the coefficient of the wind speed value V is 1.1 when the thermal comfort value of the left air supply area is calculated through the data acquired by the sensor A, and the coefficient of the wind speed value V is 0.9 when the thermal comfort value of the right air supply area is calculated through the data acquired by the sensor B;
3. taking the angle of the air guide bar as a middle position as a reference position, taking the angle of the air guide plate as XL +1, continuously adjusting the angle of the air guide plate to XL +2 leftwards, taking the angle of the air guide bar as XL +2, and taking the coefficient of the air speed value V as 1.2 when calculating the thermal comfort value of the left air supply area through the data acquired by the sensor A and taking the coefficient of the air speed value V as 0.8 when calculating the thermal comfort value of the right air supply area through the data acquired by the sensor B;
4. taking the angle of the air guide bar as a reference position, adjusting the angle of the air guide plate to the right to XR +1, wherein the angle of the air guide bar is XR +1, the coefficient of the wind speed value V is 0.9 when the thermal comfort value of the left air supply area is calculated through the data acquired by the sensor A, and the coefficient of the wind speed value V is 1.1 when the thermal comfort value of the right air supply area is calculated through the data acquired by the sensor B;
5. and taking the angle of the air guide strip as a reference position, taking the angle of the air guide plate as an XR +1, continuously adjusting the angle of the air guide plate to the left to XR +2, and when the angle of the air guide strip is XR +2, calculating the thermal comfort value of the left air supply area by using the data collected by the sensor A, wherein the coefficient of the air speed value V is 0.8, and calculating the thermal comfort value of the right air supply area by using the data collected by the sensor B, wherein the coefficient of the air speed value V is 1.2.
The reference wind speed value of the wind speed value is determined through the rotating speed of the indoor fan, and the method specifically comprises the following steps:
if the rotating speed of the indoor fan is low, taking V1 as the reference wind speed value when the thermal comfort value is calculated, and optionally, taking the value of V1 as 0.2 m/s; when the rotating speed of the indoor fan is the medium wind speed, taking V2 as a reference wind speed value when the thermal comfort value is calculated, and optionally, taking the value of V2 as 0.4 m/s; and when the rotating speed of the indoor fan is high, taking V3 as a reference wind speed value when the thermal comfort value is calculated, and optionally, taking the value of V3 as 0.6 m/s.
The method comprises the steps of obtaining a first thermal comfort value of an air supply area in a target adjusting direction, obtaining the rotating speed of an indoor fan of the air conditioner, obtaining the current angle of an air guide strip of the air conditioner, collecting a temperature value and a humidity value of the air supply area in the target adjusting direction through a sensor such as a temperature and humidity sensor which is arranged on the air conditioner and corresponds to the air supply area in the target adjusting direction, and determining the first thermal comfort value of the air supply area in the target adjusting direction according to the rotating speed of the indoor fan, the current angle of the air guide strip, the position of the sensor, the temperature value and the humidity value.
As an alternative implementation, between step S20 and step S30, the method further includes:
and controlling the air guide strips to continuously run for a preset time length according to the air guide angle adjusted by the target adjustment direction, so that the air blown out by the air conditioner is guided to the air supply area of the target adjustment direction for a long time through the air guide strips, the purpose of adjusting the thermal comfort of the air supply area of the target adjustment direction is achieved, and the first thermal comfort value of the air supply area in the target adjustment direction is accurately obtained.
Step S40, when the first thermal comfort value does not meet the comfort condition, returning to execute the step S20 until the angle of the air guide strip reaches a preset angle;
when the first thermal comfort value does not satisfy the comfort condition, that is, the air supply area in the target adjustment direction does not satisfy the comfort condition, the method returns to the step S20 of adjusting the angle of the air guide strip according to the target adjustment direction, so as to increase the air supply amount of the air supply area in the target adjustment direction guided by the air guide strip, thereby achieving the purpose of adjusting the thermal comfort of the air supply area in the target adjustment direction, until the angle of the air guide strip reaches a preset angle, and thus improving the thermal comfort of the air supply area in the target adjustment direction of the environment where the air conditioner is located to the greatest extent.
Optionally, the preset angle may be a maximum wind guiding angle of the wind guiding strip, may also be a minimum wind guiding angle of the wind guiding strip, and may also be an angle upper limit value or an angle lower limit value of a wind guiding angle range of the wind guiding strip corresponding to the air supply area of the target adjustment direction, which is not limited to this.
Alternatively, the mapping relationship between the air blowing area in the target adjustment direction, the air guide angle range of the air guide strip corresponding to the air blowing area in the target adjustment direction, and the sensor provided on the air conditioner corresponding to the air blowing area in the target adjustment direction may be set in advance. Based on the mapping relation, on the premise of acquiring the air supply area of the target adjustment direction, the air guide angle range of the air guide strip corresponding to the air supply area of the target adjustment direction can be acquired.
It should be noted that the first thermal comfort value does not satisfy comfort conditions, and the comfort conditions include:
when the air conditioner operates in a refrigeration mode, the first thermal comfort value is greater than or equal to a first preset comfort value;
when the air conditioner operates in the heating mode, the first thermal comfort value is smaller than or equal to a second preset comfort value.
The first preset comfortable value and the second preset comfortable value can be preset according to the empirical value, and optionally, the first preset comfortable value is 1.0, and the second preset comfortable value is 0.
It is understood that the first thermal comfort value satisfies comfort conditions, which include:
when the air conditioner operates in a refrigeration mode, the first thermal comfort value is smaller than a first preset comfort value;
when the air conditioner operates in the heating mode, the first thermal comfort value is larger than the second preset comfort value.
As an optional embodiment, the control method of the air conditioner further includes:
when the angle of the air guide strip reaches a preset angle, adjusting the angle of the air guide strip to an air guide angle corresponding to the maximum value in the first thermal comfort values, and operating the air conditioner in a heating mode;
when the angle of the air guide strip reaches a preset angle, the angle of the air guide strip is adjusted to the air guide angle corresponding to the minimum value in the first thermal comfort values, and the air conditioner operates in a refrigeration mode.
It is understood that the adjusting times of the angle of the wind guide strip in the step S20 is at least one time according to the target adjusting direction before the angle of the wind guide strip reaches the preset angle. After the angle of the air guide strips is adjusted according to the target adjustment direction each time, first thermal comfort values of an air supply area in the target adjustment direction are obtained, and when the adjustment times of adjusting the angle of the air guide strips according to the target adjustment direction are at least twice, the maximum value or the minimum value of the first thermal comfort values can be determined by comparing the first thermal comfort values.
The air conditioner runs in a heating mode, when the angle of the air guide strip reaches a preset angle, the angle of the air guide strip is adjusted to the air guide angle corresponding to the maximum value in each first thermal comfort value, when the air guide angle of the air guide strip is controlled to be the air guide angle corresponding to the maximum value in each first thermal comfort value, the thermal comfort requirement is met better, hot air blown out of the air conditioner is guided to an air supply area in the target adjusting direction, the temperature of the air supply area corresponding to the target thermal comfort value is increased, and the thermal comfort of the air conditioner in the air supply area corresponding to the maximum value of the first thermal comfort value in the heating mode is improved.
The air conditioner operation refrigeration mode, when the angle of wind-guiding strip reached preset angle, with the wind-guiding angle that the angular adjustment of wind-guiding strip corresponds to the minimum in each first heat comfortable value, show that the wind-guiding angle of control wind-guiding strip is when the wind-guiding angle that the minimum in each first heat comfortable value corresponds, more accord with hot comfortable demand, realize the air supply region on the cold wind direction target adjustment direction that blows off the air conditioner, with the temperature that reduces the air supply region that this target heat comfortable value corresponds, improve the air conditioner under the refrigeration mode the regional hot travelling comfort of the air supply that this first heat comfortable value's minimum corresponds.
And step S50, when the air supply area in the target adjustment direction satisfies a comfort condition, maintaining the angle of the air guide strip unchanged.
