Background
Currently, when an air conditioner is used for refrigerating or heating, the operation parameters of the air conditioner are generally adjusted only through temperature indexes.

In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:
in the related art, a temperature value with better comfort than a single temperature control effect is determined by combining the current environment parameter through the corresponding relation between the PMV value and the relative humidity and the reference air temperature parameter. The indoor humidity can not be regulated and controlled while the temperature is regulated by the scheme, so that the comfort level of a user is ideal.

With reference to fig. 1 and 2, the air conditioner comprises an air deflector 10 arranged at an air outlet of the housing and a moving assembly 20 for driving the air deflector to move. The air deflector 10 is extended or retracted into the air outlet by the moving assembly 20. Wherein, the air deflector 10 can be opened by rotating upwards or downwards when extending. Specifically, in the process of switching the air deflector 10 from the upward rotation to the downward rotation, or from the downward rotation to the upward rotation, the air deflector 10 needs to retract into the air outlet first, and then extend again to be rotated downward or rotated upward to be opened.
As shown in connection with fig. 3, an embodiment of the present disclosure provides a method for controlling an air conditioner, including:
s301, the air conditioner acquires the air inlet temperature.
S302, the air conditioner adjusts the air outlet position of the air deflector and the rotating speed of the fan according to the air inlet temperature and the set temperature.
S303, when the inlet air temperature reaches the set temperature, the sensor detects the indoor relative humidity.
S304, under the condition that the indoor relative humidity does not meet the humidity comfort condition, the air conditioner corrects the air outlet position of the air deflector and the rotating speed of the fan according to the indoor relative humidity.
Here, a temperature sensor is arranged at the air inlet of the air conditioner for acquiring the temperature of the inlet air. The air inlet temperature can represent the indoor temperature, and in this case, if the temperature sensor is not arranged at the air inlet of the air conditioner, the air inlet temperature of the air conditioner can be obtained by detecting the indoor environment temperature. And then, based on the air inlet temperature and the set temperature, adjusting the air outlet position of the air deflector and the rotating speed of the fan. Under the condition that the rotating speed of the fan is fixed, the air outlet positions of the air deflectors are different, and the air outlet amounts are different. Generally, the larger the air outlet area corresponding to the air outlet position of the air deflector is, the larger the air outlet quantity is. Similarly, when the position of the air deflector is fixed, the rotation speed of the fan is different, and the air output of the air conditioner is also different. And the higher the fan rotation speed is, the larger the air output is. The air outlet position and the rotating speed of the fan of the air deflector are adjusted, so that the air outlet quantity is changed, the indoor heat exchange quantity is changed, and the indoor ambient air is adjusted.
And when the inlet air temperature reaches the set temperature, further detecting the indoor relative humidity. The indoor relative humidity can be acquired through the indoor humidity detection sensor, and the air conditioner processor acquires the indoor relative humidity through networking. Generally, the indoor environment has a relative humidity of 40% -60%, and the indoor environment has the best humidity for the user to feel comfortable. Here, humidity comfort condition means that the indoor relative humidity is in the range of 40% -60%. And if the detected indoor relative humidity does not meet the humidity comfort condition, correcting the air outlet position of the air deflector and the rotating speed of the fan. Specifically, when the indoor relative humidity is high, the air outlet position of the air deflector and the rotating speed of the fan can be corrected to increase the air outlet quantity and accelerate the indoor heat exchange. Thereby enabling the indoor relative humidity to be reduced. When the indoor relative humidity is smaller, the air outlet position of the air deflector and the rotating speed of the fan can be corrected, so that the air outlet quantity is reduced, and the indoor heat exchange is slowed down. Thus, the indoor relative humidity can be relatively kept or slowed down, and further aggravated humidity reduction is avoided. In addition, in this embodiment, the fan rotation speed adjustment refers to adjustment of the rotation speed of the fan of the indoor unit.
By adopting the method for controlling the air conditioner, which is provided by the embodiment of the disclosure, different requirements can be met based on different air outlet positions of the air deflector. When the indoor environment is regulated, the position of the air deflector and the rotation speed of the fan are regulated according to the air inlet temperature and the set temperature of the air conditioner. Then, the position of the air deflector and the fan speed are corrected based on the indoor relative humidity. Here, the air outlet positions of the air deflectors are different, so that the indoor heat exchange condition can be changed. And further, the temperature and humidity are adjusted by controlling heat exchange. Thus, the relative humidity is adjusted while the temperature satisfies the requirement. So that the humidity also satisfies the comfort requirements of the user to the greatest extent.
Optionally, in step S302, the air conditioner adjusts the air outlet position of the air deflector and the rotational speed of the fan according to the air inlet temperature and the set temperature, including:
s321, under the condition that the difference value between the air inlet temperature and the set temperature is larger than the temperature threshold value, the air conditioner adjusts the air deflector to the maximum air outlet position, and the fan operates at the highest rotating speed.
S322, when the difference value between the air inlet temperature and the set temperature is smaller than the temperature threshold value, the air conditioner adjusts the air outlet position of the air deflector, so that the air outlet area corresponding to the adjusted air outlet position is reduced; and the rotation speed of the fan is reduced.
In the embodiment of the disclosure, the difference between the inlet air temperature and the set temperature is defined by a temperature threshold, for example, the temperature threshold takes a value of 2 ℃. When the difference between the air inlet temperature and the set temperature is larger, the current indoor temperature is indicated to be larger than the set temperature. At this time, in order to make the indoor temperature approach the set temperature as soon as possible, the maximum air outlet position of the air deflector is adjusted, and the fan is operated at the highest rotation speed. Thus, on one hand, the air outlet area of the air conditioner is increased, and on the other hand, the high wind speed is beneficial to improving the fluidity of the air. When the difference between the air inlet temperature and the set temperature is smaller, the current indoor temperature is close to the set temperature, and even the set temperature is reached. At this time, in order to provide a more comfortable environment for the user, the air outlet area corresponding to the air outlet position of the air deflector is reduced, and the rotating speed is reduced. It will be appreciated that the larger the outlet area, the higher the wind speed, and the easier the outlet is to blow to the user and the less user friendly. Therefore, the air-out area is reduced to avoid the user, and the wind speed is reduced to make the air-out soft. Thus, the comfort level of the user is also improved on the basis of meeting the temperature requirements of the user. Avoiding discomfort caused by direct blowing or strong wind.
Optionally, in step S321, when the difference between the air inlet temperature and the set temperature is greater than the temperature threshold, the air conditioner adjusts the air deflector to the maximum air outlet position, and the fan operates at the maximum rotation speed, including:
under the condition of the air conditioner operation refrigeration mode, the air conditioner adjusting air deflector is opened upwards to the maximum air outlet position.
Under the condition that the air conditioner operates in a heating mode, the air conditioner adjusts the air deflector to a cold air prevention position, and after a preset time period, the air deflector is adjusted to be opened downwards to a maximum air outlet position.
Here, the maximum air outlet position of the air deflector is determined in conjunction with the operation mode of the air conditioner. And in the air conditioner refrigerating mode, the air deflector is opened upwards to the maximum air outlet position. In this way, the cool air blown out by the air conditioner sinks, contributing to the heat exchange of the indoor air. When the air conditioner is heated, the air deflector downwards opens the maximum air outlet position. And hot air blown out by the air conditioner floats upwards to realize heat exchange. In addition, at the initial stage of starting the air conditioner, the indoor and outdoor temperature differences are large. In order to avoid cold air blowing of the air conditioner, the air deflector is controlled to be positioned at the cold air preventing position. And after the air conditioner is operated for a preset time period such as 8 minutes, adjusting the position of the air deflector at which the maximum air outlet is opened downwards.
Optionally, in step S322, when the difference between the air inlet temperature and the set temperature is smaller than the temperature threshold, the air conditioner adjusts the air outlet position of the air deflector, so as to reduce the air outlet area corresponding to the adjusted air outlet position, including:
under the condition that the air conditioner operates in a refrigerating mode, the air conditioner adjusts the air deflector to move upwards by a first angle in a rotary mode so as to reduce the air outlet area.
Under the condition that the air conditioner operates in a heating mode, the air conditioner adjusts the air deflector to rotate to move a second angle towards the direction of the air conditioner panel so as to reduce the air outlet area.
As shown in fig. 5, in the air conditioning cooling mode, the maximum air outlet position of the air deflector opened upward is a position having an included angle of 60 ° with the vertical direction, i.e., P1. And when the difference value is smaller than the temperature threshold value, the air deflector rotates upwards for a first angle. The first angle can be 10 degrees, and the angle can be set according to requirements. The position of the air deflector after adjustment is the position P2 with an included angle of 70 degrees with the vertical direction. In the air conditioning and heating mode, the maximum downward opening air outlet position of the air deflector is P3 which is the position at the left side in the vertical direction and has an included angle of 30 degrees with the vertical direction. And when the difference value is smaller than the temperature threshold value, the air deflector rotates to operate for a second angle towards the air conditioner panel. Wherein the second angle may be the same as or different from the first angle, here the second angle takes a value of 10 °. The position of the air deflector after adjustment is P4 which is the position on the left side in the vertical direction and has an included angle of 20 degrees with the vertical direction. In this way, environmental comfort is improved while meeting temperature requirements.
As shown in connection with fig. 6, an embodiment of the present disclosure provides another method for controlling an air conditioner, including:
s601, under the condition that the air conditioner operates in a heating mode, the air conditioner acquires the air inlet temperature.
S602, according to the air inlet temperature and the set temperature, the air conditioner adjusts the air outlet position of the air deflector and the rotating speed of the fan.
S603, when the inlet air temperature reaches the set temperature, the sensor detects the indoor relative humidity.
S604, when the indoor relative humidity is greater than the upper limit value of the humidity comfort condition, the air conditioner switches the operation mode to the dehumidification mode for a first duration; and correcting the air deflector to a closed or cold air prevention position, and stopping the fan.
S605, the air conditioner executes the operation mode and the operation parameters before the dehumidification mode, and operates for a second time period.
S606, the air conditioner judges whether the current indoor relative meets the humidity comfort condition, if so, S607 is executed; if not, S604 is performed.
S607, the flow ends.
In the embodiment of the disclosure, the control scheme of the air conditioner aims at the condition that the indoor temperature is low and the humidity is relatively high. After the indoor temperature reaches the set temperature, if the indoor relative humidity is large, the air conditioner is switched from a heating mode to a dehumidification mode. Here, the dehumidification mode is required to be started for dehumidification because of high relative humidity. In the dehumidification process, the indoor temperature fluctuation can be caused. The dew point temperature of the indoor evaporator is low, and frost is easily formed or condensed water is easily generated. If the fan runs and the air deflector is opened, water can be blown indoors, and user experience is affected. Therefore, the air deflector is closed or in a cold air prevention position during dehumidification, and the indoor fan is closed. Wherein, the air-out position of aviation baffle is the right side of vertical direction when preventing cold wind mode, and is 5 with the contained angle of vertical direction i.e. P5. After the dehumidification operation is performed for a first time, the air conditioner operates in a heating mode and operates with operation parameters before dehumidification. And after the second time period, judging whether the humidity is still greater than the upper limit value of the humidity comfort condition or not again. If so, the dehumidification mode is performed as above and the heating mode is performed after dehumidification until the relative humidity is reduced to a humidity comfort condition. The first time length can be 10min, and the second time length can be 45min. In this way, in the case where the heating mode cannot reduce the humidity, the deep dehumidification can be performed by operating the dehumidification mode. And simultaneously, the air outlet position of the air deflector and the rotating speed of the fan are regulated so as to reduce the influence on the indoor temperature as much as possible.
As shown in connection with fig. 7, an embodiment of the present disclosure provides another method for controlling an air conditioner, including:

In the embodiment of the disclosure, if the indoor temperature reaches the temperature, the indoor relative humidity is lower; the air outlet position of the modified air deflector is modified from the maximum air outlet position opened downwards to the vertical direction, namely from the position P3 to the position P7. When the relative humidity is low, the air outlet position of the air deflector and the rotating speed of the fan cannot be adjusted to increase the indoor humidity. But the air outlet position of the air deflector can be adjusted, so that the air outlet is more comfortable and natural. When the air outlet position of the air deflector is parallel to the vertical direction, the air outlet state is the state that the user is most comfortable, and the fan runs at a low speed.
As shown in connection with fig. 9, an embodiment of the present disclosure provides another method for controlling an air conditioner, including:
s901, under the condition that the air conditioner operates in a refrigeration mode, the air conditioner acquires the air inlet temperature.
S902, the air conditioner adjusts the air outlet position of the air deflector and the rotating speed of the fan according to the air inlet temperature and the set temperature.
S903, when the inlet air temperature reaches the set temperature, the sensor detects the indoor relative humidity.
S904, in the case where the indoor relative humidity does not satisfy the humidity comfort condition, if the indoor relative humidity is greater than the upper limit value of the humidity comfort condition (condition 1), the air conditioner performs S905; if the indoor relative humidity is less than the lower limit value of the humidity comfort condition (condition 2), the air conditioner performs S908;
s905, the air conditioner judges whether the air conditioner executes a blowing prevention function, if so, S906 is executed; if not, then S907 is performed;
s906, the air conditioner corrects the minimum air outlet position of the air deflector to be opened upwards, and the fan runs at the minimum rotation speed;
s907, the air conditioner keeps the current air outlet position of the air deflector, and adjusts the fan to run at a medium rotation speed;
s908, the air conditioner corrects the air outlet position of the air deflector to a minimum downward opening angle.
In the embodiment of the disclosure, the control scheme of the air conditioner is aimed at when the indoor temperature is high. In the refrigerating mode, if the indoor relative humidity is higher, the air outlet position of the air deflector and the rotating speed of the fan are further corrected according to whether the anti-blowing function of the air conditioner is started or not. Specifically, when the anti-blowing function is performed, the air deflector is opened upward to the minimum air outlet position, i.e., the position P6 in fig. 5. At this time, the air conditioner also has a dehumidifying function, but the relative dehumidifying rate is slow. When the anti-blowing function is not executed, the current air outlet position of the air deflector is maintained, and the fan is regulated to run at the medium rotation speed. Thus, the indoor air is quickly dehumidified, and the indoor temperature and the indoor humidity meet the requirements of users. If the indoor relative humidity is low, in order to slow down the rate of humidity reduction, the air outlet position of the air deflector is corrected to the minimum downward opening angle, namely the position P4 in the figure. Because the downward air outlet is unfavorable for heat exchange of air in the refrigerating mode, the humidity reducing rate can be slowed down. Thereby avoiding the drying of indoor air and causing discomfort to users.
The embodiment of the disclosure provides a device for controlling an air conditioner, which comprises an acquisition module, an adjustment module, a detection module and a correction module. The acquisition module is configured to acquire the air inlet temperature of the air conditioner; the adjusting module is configured to adjust the air outlet position of the air deflector and the rotating speed of the fan according to the air inlet temperature and the set temperature; the detection module is configured to detect indoor relative humidity under the condition that the inlet air temperature reaches a set temperature; the correction module is configured to correct the air outlet position of the air deflector and the rotational speed of the fan according to the indoor relative humidity when the indoor relative humidity does not meet the humidity comfort condition.
By adopting the device for controlling the air conditioner, which is provided by the embodiment of the disclosure, different requirements are met based on different air outlet positions of the air deflector. When the indoor environment is regulated, the position of the air deflector and the rotation speed of the fan are regulated according to the air inlet temperature and the set temperature of the air conditioner. Then, the position of the air deflector and the fan speed are corrected based on the indoor relative humidity. Here, the air outlet positions of the air deflectors are different, so that the indoor heat exchange condition can be changed. And further, the temperature and humidity are adjusted by controlling heat exchange. Thus, the relative humidity is adjusted while the temperature satisfies the requirement. So that the humidity also satisfies the comfort requirements of the user to the greatest extent.
