[0031] An embodiment of the present invention provides an air outlet control method for an air conditioner. Figure 1 Schematic diagram of the positions of the wind guide plate and the swing blade in the embodiment of the present invention. Figure 1As shown, an air guide plate is arranged in the air outlet duct of the air conditioner, and a swing blade rotatable relative to the air guide plate is arranged on the air guide plate, and a ventilation hole is opened on the swing blade. Figure 2 As shown, the air conditioning air outlet control method may include the following steps S101 to S103.

[0032] S101: In response to a first air-conditioning start-up instruction, controlling the swing blades to be at a first air outlet angle.

[0033] It should be noted that the first air conditioner start instruction is used to start the preset windless mode of the air conditioner, so that the air conditioner can run in a windy state until the temperature reaches the target temperature, and then switch to the windless state of the air conditioner. Before the ambient temperature reaches the target temperature, the swing blade is controlled to be at the first air outlet angle. The first air outlet angle can reduce the dispersion of the air outlet of the air conditioner by the ventilation holes of the swing blade, and the air outlet of the air conditioner is in a windy state. Therefore, the first air outlet angle can be a first angle between the blade surface of the swing blade and the air flow direction in the air outlet duct, and the first angle is less than 45 degrees. Reference Figure 3 As shown, in some embodiments, the angle between the blade surface of the swing blade and the airflow direction in the air outlet duct is 0 degrees, that is, the first air outlet angle is that the blade surface of the swing blade is parallel to the airflow direction in the air outlet duct, so that the airflow in the air outlet duct flows through the gaps between different swing blades. At this time, the ventilation holes on the swing blades minimize the dispersion of the air outlet of the air conditioner, and the air outlet of the air conditioner can directly enter the indoor environment. The ambient temperature can quickly reach the target temperature, which improves the temperature control efficiency of the air conditioner before reaching the target temperature.

[0034] S102: During the operation of the air conditioner, a temperature deviation between the ambient temperature of the environment where the air conditioner is located and a target temperature is obtained.

[0035] In some embodiments, obtaining the temperature deviation between the ambient temperature of the environment in which the air conditioner is located and the target temperature may include: if the air conditioner is operating in a cooling condition, obtaining the ambient temperature of the environment in which the air conditioner is located, and taking the difference between the ambient temperature and the target temperature as the temperature deviation; if the air conditioner is operating in a heating condition, obtaining the ambient temperature of the environment in which the air conditioner is located, and taking the difference between the target temperature and the ambient temperature as the temperature deviation.

[0036] Wherein, obtaining the ambient temperature of the environment where the air conditioner is located may include: obtaining the ambient temperature of the environment where the air conditioner is located through a sensor at every preset waiting time. The sensor may be a thermistor sensor, a thermocouple sensor, a temperature sensor, a platinum thermal resistance temperature sensor, and a digital output sensor. The waiting time may be 10 seconds, 1 minute, or 10 minutes, which is not specifically limited here.

[0037] It is understandable that before step S102, the method may further include: obtaining a target temperature. Specifically, the method of obtaining the target temperature may be: using a temperature value preset by the user as the target temperature, or using a temperature value determined by a user's selection operation as the target temperature.

[0038] During the time when the temperature deviation is not less than the first preset temperature difference threshold, the swing blade can be maintained at the first air outlet angle until the temperature deviation is reduced to less than the first preset temperature difference threshold.

[0039] S103: If the temperature deviation decreases to less than the first preset temperature difference threshold, the control swing blade is changed from the first air outlet angle to the second air outlet angle, wherein the projection area of ​​the swing blade perpendicular to the air outlet direction at the second air outlet angle is greater than the projection area of ​​the swing blade perpendicular to the air outlet direction at the first air outlet angle.

[0040] It should be noted that since the projection area of ​​the swing blade perpendicular to the air outlet direction at the second air outlet angle is larger than the projection area of ​​the swing blade perpendicular to the air outlet direction at the first air outlet angle, the air volume passing through the ventilation holes on the swing blade at the second air outlet angle is larger than the air volume passing through the ventilation holes of the swing blade at the first air outlet angle.

[0041] It should be noted that when the temperature deviation is reduced to less than the first preset temperature difference threshold, it indicates that the ambient temperature is very close to the target temperature, that is, the ambient temperature of the environment where the air conditioner is located reaches the target temperature. The first preset temperature difference threshold is a smaller value, for example, it can be 0.1°C, 1°C or 2°C, etc., which is not specifically limited here. Since the ambient temperature of the environment where the air conditioner is located reaches the target temperature, it is necessary to control the air conditioner to turn on the windless effect to improve human comfort, so the swing blade is controlled to change from the first air outlet angle to the second air outlet angle. The swing blade is controlled to be at the second air outlet angle. The second air outlet angle can increase the dispersion of the air outlet of the air conditioner by the ventilation holes of the swing blade and weaken the wind speed. Therefore, the second air outlet angle can be a second angle between the blade surface of the swing blade and the airflow direction in the air outlet duct, and the second angle is not less than 45 degrees. Reference Figure 4 As shown, in some embodiments, the angle between the blade surface of the swing blade and the air flow direction in the air outlet duct is 90 degrees, that is, the second air outlet angle is that the blade surface of the swing blade is perpendicular to the air flow direction in the air outlet duct, so that the air flow in the air outlet duct flows through the ventilation holes of the swing blade. At this time, the ventilation holes on the swing blade have the greatest dispersion of the air-conditioning outlet, and the air-conditioning outlet can enter the environment after passing through the ventilation holes on the swing blade, thereby weakening the wind speed and achieving a windless state at the air outlet of the air conditioner, thereby achieving a windless effect, thereby improving human comfort.

[0042] It should be noted that after the temperature deviation decreases to less than the first preset temperature difference threshold, that is, after the ambient temperature of the environment where the air conditioner is located reaches the target temperature, the ambient temperature may deviate from the target temperature again. Therefore, in some embodiments, it may also include: after controlling the swing blade to change from the first air outlet angle to the second air outlet angle, if the temperature deviation increases to be greater than the second preset temperature difference threshold, controlling the swing blade to change from the second air outlet angle back to the first air outlet angle so as to return to the wind-feeling state of the air outlet of the air conditioner, and the second preset temperature difference threshold is greater than or equal to the first preset temperature difference threshold.

[0043] When the temperature deviation increases to be greater than the second preset temperature difference threshold, the swing blade is controlled to change from the second air outlet angle back to the first air outlet angle, reducing the dispersion of the air outlet of the air conditioner by the ventilation holes on the swing blade, so that the air outlet of the air conditioner directly enters the environment where the air conditioner is located, so that the ambient temperature of the environment where the air conditioner is located can quickly reach the target temperature again, thereby improving the temperature control efficiency of the air conditioner. In addition, each time the temperature deviation increases to be greater than the second preset temperature difference threshold, the air conditioner can monitor the temperature change in time and adjust the ambient temperature to prevent a large deviation between the ambient temperature and the target temperature, thereby improving the accuracy of the temperature control of the air conditioner.

[0044] It should be noted that the second preset temperature difference threshold is greater than the first preset temperature difference threshold to achieve hysteresis control, which can prevent the swing blades from frequently rotating and changing states, reduce the number of times the swing blades switch back and forth between the first air outlet angle and the second air outlet angle, and extend the service life of the swing blades.

[0045] It is understandable that if the air conditioner has a first air outlet and a second air outlet connected to the air outlet duct, the air outlet directions of the first air outlet and the second air outlet are different, and the air guide plate is rotatably arranged in the air outlet duct. Then, the air conditioner air outlet control method provided by the embodiment of the present invention may also include the steps of: determining the target air outlet direction in response to the first air conditioner start-up instruction;

[0046] If the target air outlet direction is toward the first air outlet, the air guide plate is controlled to rotate to an angle to block the second air outlet so that the air conditioner discharges air to the first air outlet through the air outlet duct; if the target air outlet direction is toward the second air outlet, the air guide plate is controlled to rotate to an angle to block the first air outlet so that the air conditioner discharges air to the second air outlet through the air outlet duct.

[0047] refer to Figure 5 , Figure 6 As shown, the first air outlet may be a side air outlet, and the second air outlet may be a lower air outlet.

[0048] In order to facilitate understanding of the process of controlling the air outlet of the air conditioner by combining the air guide plate and the swing blade, the air outlet of the first air outlet and the air outlet of the second air outlet are respectively described below:

[0049] like Figure 5 As shown, in some embodiments, before the temperature deviation is not less than the first preset temperature difference threshold, the air guide plate is controlled to rotate to an angle that blocks the second air outlet, and the swing blade is at the first air outlet angle, so that the air outlet of the air conditioner from the first air outlet is in a windy state, thereby improving the temperature control efficiency of the air outlet coverage area of ​​the first air outlet. After the temperature deviation is reduced to less than the first preset temperature difference threshold, the angle of the air guide plate does not change, and only the swing blade is controlled to rotate to the second air outlet angle to increase the dispersion of the air outlet of the air conditioner by the ventilation holes of the swing blade, so that the air outlet of the air conditioner from the first air outlet is changed to a windless state, thereby improving human comfort. At the same time, a targeted balance between the air conditioning temperature control efficiency and human comfort in a specific area is achieved.

[0050] In other embodiments, reference Figure 6 As shown, before the temperature deviation is not less than the first preset temperature difference threshold, the air guide plate is controlled to rotate to an angle that blocks the first air outlet, and the swing blade is at the first air outlet angle, so that the air outlet of the air conditioner from the second air outlet is in a windy state, thereby improving the temperature control efficiency of the air outlet coverage area of ​​the second air outlet. After the temperature deviation is reduced to less than the first preset temperature difference threshold, the angle of the air guide plate does not change, and only the swing blade is controlled to rotate to the second air outlet angle to increase the dispersion of the air outlet of the air conditioner by the ventilation holes of the swing blade, so that the air outlet of the air conditioner from the second air outlet is changed to a windless state, thereby improving human comfort. At the same time, a targeted balance between the air conditioning temperature control efficiency and human comfort in a specific area is achieved.

[0051] It should be noted that the number of air outlets of the air conditioner is not limited to 2, but may be 3, 4 or 5, and no specific limitation is made here. According to the different number of air outlets, the above-mentioned determination of the target air outlet direction and the corresponding adjustment made by controlling the rotation of the air guide plate are all included in the scope of protection of the present invention.

[0052] It can be understood that if the air conditioner has a first air outlet and a second air outlet connected to the air outlet duct, the air outlet directions of the first air outlet and the second air outlet are different, and the air guide plate is rotatably arranged in the air outlet duct, then, in some embodiments, the air outlet control method of the air conditioner provided in the embodiment of the present invention may also include: if a second air conditioner start-up instruction different from the first air conditioner start-up instruction is obtained, determining a target air outlet direction in response to the second air conditioner start-up instruction; if the target air outlet direction is the direction of air outlet toward the first air outlet, controlling the air guide plate to rotate to an angle to block the second air outlet and keeping the swing blade unchanged at the first air outlet angle, so that the air conditioner The air is adjusted to discharge air toward the first air outlet through the air outlet duct and the gap between different swing blades; if the target air outlet direction is the direction of air outlet toward the second air outlet, the air guide plate is controlled to rotate to an angle to block the first air outlet and the swing blades are kept at the first air outlet angle, so that the air conditioner discharges air toward the second air outlet through the air outlet duct and the gap between different swing blades; if the target air outlet direction is the direction of air outlet toward the first air outlet and the second air outlet, the air guide plate is controlled to rotate to an angle to expose the first air outlet and the second air outlet and the swing blades are kept at the first air outlet angle, so that the air conditioner discharges air toward the first air outlet and the second air outlet through the air outlet duct and the gap between different swing blades.

[0053] It should be noted that the second air-conditioning start instruction is used to start the preset wind-sensing mode of the air-conditioning, so that the air outlet of the air-conditioning is in a continuous wind-sensing state.

[0054] In some embodiments, the air guide plate and the swing blade are combined to control the air outlet effect of the air conditioner, refer to Figure 5 As shown, by controlling the air guide plate to rotate to an angle that blocks the second air outlet, and keeping the swing blade at the first air outlet angle unchanged, the air outlet of the air conditioner from the first air outlet is in a windy state, thereby improving the temperature control efficiency of the air outlet coverage area of ​​the first air outlet. Therefore, the temperature control efficiency of the air conditioner in a specific area is improved.

[0055] In some embodiments, reference Figure 6 As shown, by controlling the air guide plate to rotate to an angle that blocks the first air outlet, and keeping the swing blade at the first air outlet angle unchanged, the air outlet of the air conditioner from the second air outlet is in a windy state, thereby improving the temperature control efficiency of the air outlet coverage area of ​​the second air outlet. Therefore, the temperature control efficiency of the air conditioner in a specific area is improved.

[0056] In some embodiments, reference Figure 7 As shown, by controlling the air guide plate to rotate to an angle that exposes the first air outlet and the second air outlet, and keeping the swing blade at the first air outlet angle unchanged, the air outlet of the air conditioner from the first air outlet and the second air outlet is in a wind-feeling state, thereby improving the temperature control efficiency of the coverage area facing the first air outlet and the second air outlet.

[0057] There are many ways to determine the target air outlet direction, which are described below by way of example:

[0058] In some embodiments, determining the target air outlet direction may include: obtaining a user position; and determining the target air outlet direction according to the user position so that the air outlet of the air conditioner is directed toward the user position.

[0059] Specifically, determining the target air outlet direction according to the user position may include: if the user position is in the first area, taking the air outlet direction toward the first air outlet as the target air outlet direction, and the first area is the corresponding air outlet coverage area when the air outlet duct discharges air toward the first air outlet. If the user position is in the second area, taking the air outlet direction toward the second air outlet as the target air outlet direction, and the second area is the corresponding air outlet coverage area when the air outlet duct discharges air toward the second air outlet.

[0060] It is understandable that the method for obtaining the user's position may be to obtain the user's position through a sensor, and the sensor may be a photoelectric sensor, an infrared sensor, or a contactless proximity sensor.

[0061] It should be noted that by determining the target air outlet direction according to the user's location, it is possible to maximize the use of the air outlet of the air conditioner, so that the air conditioner can track the user's location for precise air supply, and the air outlet of the air conditioner can always act on the area where the user is located, reducing user operations.

[0062] In other implementations, determining the target air outlet direction may include: obtaining a wind direction selection operation of a user; and determining the target air outlet direction according to the wind direction selection operation.

[0063] Based on one or more embodiments of the air conditioner air outlet control method provided by the embodiment of the present invention, the air conditioner temperature control efficiency is improved before the target temperature is reached. The human body comfort is improved after the target temperature is reached. Therefore, the air conditioner temperature control efficiency and human body comfort are balanced.

[0064] In order to facilitate understanding of the air conditioning outlet control method provided by the embodiment of the present invention, the air conditioning outlet includes a side outlet and a lower outlet, and two air supply modes, a no-wind mode and a wind-feeling mode, are configured under the cooling condition as an example to illustrate the air conditioning outlet control process.

[0065] Step 1: After the air conditioner is started, if the user's first air conditioner start command is received, the air conditioner enters the windless mode, triggering the execution of the following steps 2 to 3; if the user's second air conditioner cooling start command is received, the air conditioner enters the windy mode, triggering the execution of the following step 4;

[0066] Step 2: If the user's selected operation is side air outlet, the air guide plate is controlled to rotate to block the lower air outlet, and the swing blade is controlled to be at the first air outlet angle, that is, the page of the swing blade follows the air flow direction; if the user's selected operation is lower air outlet, the air guide plate is controlled to rotate to block the side air outlet, and the swing blade is controlled to be at the first air outlet angle, that is, the page of the swing blade follows the air flow direction;
