With reference to Figures 1 and 2, the air conditioner includes an air guide plate 10 disposed at the air outlet of the housing and a movement component 20 that drives the air guide plate to move. The air guide plate 10 extends or retracts the air outlet under the action of the moving assembly 20 . When the air guide plate 10 is extended, it can be rotated upward to open, or rotated downward to open. Specifically, when the air guide plate 10 switches from upward rotation to downward rotation, or from downward rotation to upward rotation, the air guide plate 10 needs to retract the air outlet first, and then extend again to rotate downward or upward. Open.

As shown in FIG. 3 , an embodiment of the present disclosure provides a method for controlling air conditioning, including:

S301, the air conditioner obtains its inlet air temperature.

S302, the air conditioner adjusts the air outlet position of the air guide plate and the fan speed according to the inlet air temperature and the set temperature.

S303, when the inlet air temperature reaches the set temperature, the sensor detects the indoor relative humidity.

S304, when the indoor relative humidity does not meet the humidity comfort conditions, the air conditioner corrects the air outlet position of the air guide plate and the fan speed according to the indoor relative humidity.

Here, a temperature sensor is installed at the air inlet of the air conditioner to obtain the inlet air temperature. The inlet air temperature can represent the indoor temperature. In this case, if there is no temperature sensor installed at the air inlet of the air conditioner, the inlet air temperature of the air conditioner can be obtained by detecting the indoor ambient temperature. Then, based on the inlet air temperature and the set temperature, the air outlet position of the air guide plate and the fan speed are adjusted. Among them, when the fan speed is constant, the air outlet position of the air guide plate is different, and the air outlet volume is different. Generally, the larger the air outlet area corresponding to the air outlet position of the air guide plate, the greater the air outlet volume. Similarly, when the position of the air guide plate is fixed, the fan speed is different, and the air output volume of the air conditioner is also different. And the higher the fan speed, the greater the air output. By adjusting the air outlet position of the air guide plate and the fan speed, the air outlet volume is changed to change the indoor heat exchange amount and adjust the indoor ambient air.

When the inlet air temperature reaches the set temperature, the indoor relative humidity is further detected. Among them, the indoor relative humidity can be obtained through the indoor humidity detection sensor, and the air conditioning processor can obtain the indoor relative humidity through the Internet. Generally, the relative humidity of the indoor environment is between 40% and 60%, which is the optimal humidity for users to feel comfortable. Here, the humidity comfort condition means that the indoor relative humidity is in the range of 40%-60%. If the detected indoor relative humidity does not meet the humidity comfort conditions, correct the air outlet position of the air deflector and the fan speed. Specifically, when the indoor relative humidity is high, the air outlet position of the air guide plate and the fan speed can be modified to increase the air outlet volume and accelerate indoor heat exchange. This allows the indoor relative humidity to be reduced. When the indoor relative humidity is low, the air outlet position of the air deflector and the fan speed can be modified to reduce the air outlet volume and slow down indoor heat exchange. This allows the indoor relative humidity to be relatively maintained or slowed down to avoid further aggravating the decrease in humidity. In addition, in this embodiment, the adjustment of the fan speed refers to the adjustment of the indoor unit fan speed.

Using the method for controlling air conditioning provided by embodiments of the present disclosure, different needs can be met based on different air outlet positions of the air guide plate. When adjusting the indoor environment, first adjust the position of the air deflector and the fan speed according to the air conditioner inlet air temperature and set temperature. Then, based on the indoor relative humidity, the position of the air deflector and the fan speed are corrected. Here, the air outlet positions of the air guide plates are different, which can change the indoor heat exchange situation. Then, by controlling the heat exchange, the temperature and humidity can be adjusted. In this way, the relative humidity can be adjusted while the temperature meets the requirements. So that the humidity can also meet the user's comfort requirements to the greatest extent.

Optionally, in step S302, the air conditioner adjusts the air outlet position of the air guide plate and the fan speed according to the inlet air temperature and the set temperature, including:

S321, when the difference between the inlet air 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 runs at the highest speed.

S322, when the difference between the inlet air temperature and the set temperature is less than the temperature threshold, the air conditioner adjusts the air outlet position of the air guide plate to reduce the air outlet area corresponding to the adjusted air outlet position; and reduces the fan speed.

In the embodiment of the present disclosure, a temperature threshold is used to define the difference between the inlet air temperature and the set temperature. For example, the temperature threshold takes a value of 2°C. When the difference between the inlet air temperature and the set temperature is large, it indicates that the current indoor temperature is significantly different from the set temperature. At this time, in order to bring the indoor temperature close to the set temperature as quickly as possible, adjust the air guide plate to the maximum air outlet position, and at the same time, the fan runs at the highest speed. In this way, on the one hand, the air outlet area of the air conditioner is increased, and on the other hand, the high wind speed helps improve the flow of air. When the difference between the inlet air temperature and the set temperature is small, it indicates that the current indoor temperature is close to the set temperature or has even reached the set temperature. At this time, in order to provide users with a more comfortable environment, the air outlet area corresponding to the air outlet position of the air guide plate is reduced, and the rotation speed is reduced at the same time. Understandably, the larger the air outlet area and the higher the wind speed, the easier it is for the air to blow toward users and the less user-friendly it is. Therefore, adjust the air outlet area to avoid users, and reduce the wind speed to make the air outlet gentle. In this way, on the basis of meeting the user's temperature needs, it also improves the user's comfort. Avoid direct blowing or strong wind causing discomfort to the user.

Optionally, in step S321, when the difference between the inlet air 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 runs at the highest speed, including:

When the air conditioner is running in the cooling mode, the air conditioning guide plate opens upward to the maximum air outlet position.

When the air conditioner is running in the heating mode, the air conditioner adjusts the air deflector to the cold wind prevention position, and after a preset time, adjusts the air deflector to open downward to the maximum air outlet position.

Here, combined with the operating mode of the air conditioner, the maximum air outlet position of the air deflector is determined. When the air conditioner is in cooling mode, the air deflector opens upward to the maximum air outlet position. In this way, the cold air blown by the air conditioner sinks, which helps the heat exchange of indoor air. When the air conditioner is heating, the air deflector opens downward to the maximum air outlet position. The hot air blown out by the air conditioner floats up to achieve heat exchange. In addition, in the early stages of air conditioning startup, the temperature difference between indoor and outdoor air is large. In order to prevent the air conditioner from blowing cold wind, first control the air deflector to the anti-cold wind position. After the air conditioner runs for a preset time of, for example, 8 minutes, adjust the air deflector downward to open the maximum air outlet position.

Optionally, in step S322, when the difference between the inlet air temperature and the set temperature is less than the temperature threshold, the air conditioner adjusts the air outlet position of the air guide plate to reduce the air outlet area corresponding to the adjusted air outlet position, including :

When the air conditioner operates in the cooling mode, the air conditioner adjusts the air deflector to rotate upward at a first angle to reduce the air outlet area.

When the air conditioner operates in the heating mode, the air conditioner adjusts the air deflector to rotate and move toward the air conditioner panel at a second angle to reduce the air outlet area.

As shown in Figure 5, in the air-conditioning cooling mode, the maximum air outlet position of the upward opening of the air guide is the position with an angle of 60° from the vertical direction, that is, P1. When the difference is less than the temperature threshold, the air guide plate rotates upward at a first angle. The first angle can be 10°, and the angle can be set according to the needs. The adjusted position of the air deflector is at an angle of 70° with the vertical direction, which is P2. In the air-conditioning and heating mode, the maximum air outlet position of the downward opening of the air deflector is the position on the left side of the vertical direction and an angle of 30° with the vertical direction, which is P3. When the difference is less than the temperature threshold, the air guide plate rotates toward the air conditioning panel at a second angle. The second angle may be the same as or different from the first angle. Here, the second angle takes a value of 10°. Then the position of the adjusted air deflector is on the left side of the vertical direction and the angle between it and the vertical direction is 20°, which is P4. In this way, environmental comfort is improved while meeting temperature requirements.

As shown in FIG. 6 , an embodiment of the present disclosure provides another method for controlling air conditioning, including:

S601, when the air conditioner is running in the heating mode, the air conditioner obtains the inlet air temperature.

S602, according to the inlet air temperature and the set temperature, the air conditioner adjusts the air outlet position of the air deflector and the fan speed.

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 of humidity comfort conditions, the air conditioner switches the operating mode to the dehumidification mode for the first period of time; and corrects the air deflector to the closed or anti-cold wind position, and the fan stops.

S605: The air conditioner executes the operating mode and operating parameters before the dehumidification mode and runs for the second time.

S606: The air conditioner determines whether the current indoor relative humidity conditions are met. If yes, S607 is executed; if not, S604 is executed.

S607, the process ends.

In the embodiment of the present disclosure, a control scheme for air conditioning is provided when 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 high, the air conditioner switches from heating mode to dehumidification mode. Here, because the relative humidity is high, it is necessary to activate the dehumidification mode for dehumidification. The dehumidification process will not only cause fluctuations in indoor temperature. It will also cause the dew point temperature of the indoor evaporator to be low, making it easy for frost or condensation to occur. If the fan is running and the air deflector is open, water will be blown into the room, affecting the user experience. Therefore, during dehumidification, the air deflector is closed or in the cold wind protection position, and the indoor fan is turned off. Among them, in anti-cold wind mode, the air outlet position of the air guide plate is on the right side of the vertical direction, and the angle with the vertical direction is 5°, that is, P5. After the first period of dehumidification operation, the air conditioner runs in the heating mode and operates with the operating parameters before dehumidification. After the second period of time, determine again whether the humidity is still greater than the upper limit of humidity comfort conditions. If it is greater, dehumidification mode is performed as above, and heating mode is performed after dehumidification until the relative humidity is reduced to humidity comfort conditions. Among them, the first duration can take a value of 10 minutes, and the second duration can take a value of 45 minutes. In this way, when the heating mode cannot reduce the humidity, the dehumidification mode can be operated for deep dehumidification. At the same time, adjust the air outlet position of the air deflector and the fan speed to minimize the impact on the indoor temperature.

As shown in FIG. 7 , an embodiment of the present disclosure provides another method for controlling air conditioning, including:

S701, when the air conditioner is running in the heating mode, the air conditioner obtains the inlet air temperature.

S702, the air conditioner adjusts the air outlet position of the air guide plate and the fan speed based on the inlet air temperature and the set temperature.

S703, when the inlet air temperature reaches the set temperature, the sensor detects the indoor relative humidity.

S704, when the indoor relative humidity is greater than the upper limit of humidity comfort conditions, the air conditioner switches the operating mode to the dehumidification mode for the first period of time; and corrects the air deflector to the closed or anti-cold wind position, and the fan stops.

S705, the air conditioner executes the operating mode and operating parameters before the dehumidification mode, and runs for the second time.

S706: The air conditioner determines whether the current indoor relative humidity conditions are met. If yes, S707 is executed; if not, S704 is executed.

S707, the air conditioner runs in heating mode, adjust the air deflector to the maximum air outlet position where it opens upward, and the fan runs at medium speed.

S708, after the third period of time, the air conditioner adjusts the air deflector to the maximum air outlet position where it opens downward, and the fan runs at the lowest speed.

In the embodiment of the present disclosure, after the air conditioner operates in the dehumidification mode and the humidity meets the humidity comfort condition, the heating mode is operated again. At this time, adjust the air deflector to the maximum air outlet position where it opens upward, and the fan runs at medium speed. In this way, after dehumidification, the indoor temperature can be quickly compensated by adjusting the air outlet position of the air guide plate and the fan speed to reduce fluctuations in indoor temperature. And after the third period of time, such as 5min-10min, adjust the air deflector to the maximum air outlet position that opens downward, and the fan runs at the lowest speed. In heating mode, when the air deflector is opened downward to the maximum air outlet position, it can not only ensure a constant indoor temperature, but also improve the user's experience.

As shown in FIG. 8 , an embodiment of the present disclosure provides another method for controlling air conditioning, including:

S801, when the air conditioner is running in the heating mode, the air conditioner obtains the inlet air temperature.

S802, the air conditioner adjusts the air outlet position of the air guide plate and the fan speed based on the inlet air temperature and the set temperature.

S803, when the inlet air temperature reaches the set temperature, the sensor detects the indoor relative humidity.

S804: The air conditioner determines whether the indoor relative humidity meets the humidity comfort condition. If yes, S805 is executed; if not, S806 is executed.

S805, the air conditioner adjusts the air deflector to the maximum air outlet position where it opens downward, and the fan runs at the lowest speed.

S806: The air conditioner determines that the indoor relative humidity is greater than the upper limit of the humidity comfort condition (Condition 1), or the indoor relative humidity is less than the lower limit of the humidity comfort condition (Condition 2); if Condition 1 is met, execute S807; if If condition 2 is met, S812 is executed.

S807, the air conditioner switches the operating mode to the dehumidification mode and runs for the first time; and corrects the air deflector to the closed or cold wind prevention position, and the fan stops.

S808: The air conditioner executes the operating mode and operating parameters before the dehumidification mode and runs for the second time.

S809: The air conditioner determines whether the current indoor relative humidity meets the humidity comfort conditions. If yes, S810 is executed; if not, S807 is executed.

S810, the air conditioner runs in heating mode, adjust the air deflector to the maximum air outlet position where it opens upward, and the fan runs at medium speed.

S811, after the third period of time, the air conditioner adjusts the air deflector to the maximum air outlet position where it opens downward, and the fan runs at the lowest speed.

S812, the air conditioner corrects the air outlet position of the air deflector to the vertical direction.

In the embodiment of the present disclosure, if the indoor temperature reaches the maximum temperature and the indoor relative humidity is low, the air outlet position of the air guide plate is corrected from the maximum air outlet position opened downward to the vertical direction, that is, from the position P3 to P7 . When the relative humidity is low, adjusting the air outlet position of the air deflector and the fan speed cannot increase indoor humidity. However, the air outlet position of the air deflector can be adjusted to make the air outlet more comfortable and natural. When the air outlet position of the air guide plate is parallel to the vertical direction, the air outlet state is the most comfortable wind state for the user, and the fan runs at low speed.

As shown in FIG. 9 , an embodiment of the present disclosure provides another method for controlling air conditioning, including:

S901, when the air conditioner is running in the cooling mode, the air conditioner obtains the inlet air temperature.

S902, the air conditioner adjusts the air outlet position of the air guide plate and the fan speed based on the inlet air temperature and the set temperature.

S903, when the inlet air temperature reaches the set temperature, the sensor detects the indoor relative humidity.

S904, when the indoor relative humidity does not meet the humidity comfort condition, if the indoor relative humidity is greater than the upper limit of the humidity comfort condition (Condition 1), the air conditioner executes S905; if the indoor relative humidity is less than the lower limit of the humidity comfort condition (Condition 1) Condition 2), then the air conditioner executes S908;

S905, the air conditioner determines whether the air conditioner performs the anti-blowing function. If so, execute S906; if not, execute S907;

S906, the air conditioner corrects the wind guide plate to open upward to the minimum air outlet position, and the fan runs at the minimum speed;

S907, the air conditioner maintains the current air outlet position of the air deflector and adjusts the fan to run at medium speed;

S908, the air conditioner corrects the air outlet position of the air deflector to the minimum downward opening angle.

In the embodiment of the present disclosure, a control scheme for air conditioning is provided when the indoor temperature is high. In the cooling mode, if the indoor relative humidity is high, the air outlet position of the air guide plate and the fan speed will be corrected based on whether the anti-blowing function of the air conditioner is turned on. Specifically, when performing the anti-blowing function, the air guide plate is opened upward to the minimum air outlet position, which is the P6 position in Figure 5. At this time, the air conditioner also has a dehumidification function, but the dehumidification rate is relatively slow. When the anti-blowing function is not executed, the current air outlet position of the air guide plate is maintained, and the fan is adjusted to run at a medium speed. In this way, it helps to quickly dehumidify the indoor air, so that the indoor temperature and humidity can meet the user's needs. If the indoor relative humidity is low, in order to slow down the rate of humidity reduction, correct the air outlet position of the air deflector to the minimum downward opening angle, which is the P4 position in the figure. Because in the cooling mode, the downward air outlet is not conducive to the heat exchange of the air, so it can slow down the humidity reduction rate. This prevents the indoor air from drying out and causing user discomfort.

Embodiments of the present disclosure provide a device for controlling air conditioning, including an acquisition module, an adjustment module, a detection module and a correction module. The acquisition module is configured to obtain the inlet air temperature of the air conditioner; the adjustment module is configured to adjust the air outlet position of the air guide plate and the fan speed according to the inlet air temperature and the set temperature; the detection module is configured to adjust the air inlet temperature to the set temperature when the inlet air temperature reaches the set temperature. In the case of indoor relative humidity, the correction module is configured to correct the air outlet position of the air guide plate and the fan speed according to the indoor relative humidity when the indoor relative humidity does not meet the humidity comfort conditions.

The device for controlling the air conditioner provided by the embodiment of the present disclosure is used to meet different needs based on different air outlet positions of the air guide plate. When adjusting the indoor environment, first adjust the position of the air deflector and the fan speed according to the air conditioner inlet air temperature and set temperature. Then, based on the indoor relative humidity, the position of the air deflector and the fan speed are corrected. Here, the air outlet positions of the air guide plates are different, which can change the indoor heat exchange situation. Then, by controlling the heat exchange, the temperature and humidity can be adjusted. In this way, the relative humidity can be adjusted while the temperature meets the requirements. So that the humidity can also meet the user's comfort requirements to the greatest extent.
