[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] See also Figure 1 , Figure 1 : is a flow chart of an air conditioning control method provided by an embodiment of the present application. As shown in the figure, the air conditioning control method includes the following steps:

[0040] Step 101: When an air conditioner is in a cooling mode, obtain the humidity of an indoor environment corresponding to the air conditioner and a first rotation speed of a cooling fan of the air conditioner.

[0041] Among them, the specific method of obtaining the indoor environment corresponding to the air conditioner is not limited here. As an optional implementation, the air conditioner is provided with a humidity sensor, and obtaining the humidity of the indoor environment corresponding to the air conditioner includes: detecting the humidity of the indoor environment corresponding to the air conditioner through the humidity sensor.

[0042] In the implementation manner of the present application, the humidity of the indoor environment corresponding to the air conditioner is detected by a humidity sensor installed on the air conditioner, so that the accuracy of the humidity detection result can be higher.

[0043] As another optional implementation, a humidity sensor can be installed in the indoor environment corresponding to the air conditioner, and the air conditioner can be communicatively connected to the humidity sensor. In this way, the humidity sensor can detect the humidity of the indoor environment corresponding to the air conditioner and send the detected humidity of the indoor environment corresponding to the air conditioner to the air conditioner, thereby increasing the diversity of humidity detection methods.

[0044] Among them, the specific method of obtaining the first speed of the cooling fan of the air conditioner is not limited here. As an optional implementation, a speed sensor can be provided to detect the first speed of the cooling fan of the air conditioner, or, as another optional implementation, it can be obtained by converting the driving electrical signal of the cooling fan.

[0045] It should be noted that the cooling fan may refer to a fan in an air conditioner used to cool the indoor environment.

[0046] Step 102: When the humidity of the indoor environment corresponding to the air conditioner is greater than a first threshold and the first speed of the cooling fan of the air conditioner is greater than a second threshold, or when the value calculated based on the humidity of the indoor environment corresponding to the air conditioner and the first speed is less than a third threshold, the speed of the cooling fan is adjusted from the first speed to a second speed, and the second speed is less than the first speed.

[0047] In an embodiment of the present application, when the humidity of the indoor environment corresponding to the air conditioner is greater than a first threshold value and the first speed of the cooling fan of the air conditioner is greater than a second threshold value, or when the value calculated based on the humidity of the indoor environment corresponding to the air conditioner and the first speed is less than a third threshold value, it indicates that the humidity of the indoor environment is relatively high at this time and the air conditioner is mainly used for cooling. The speed of the cooling fan can be adjusted from the first speed to the second speed, thereby reducing the cooling capacity of the air conditioner and thereby improving the dehumidification capacity of the air conditioner, that is, enhancing the dehumidification effect of the air conditioner, thereby enhancing the user's comfort and user experience.

[0048] It should be noted that the value calculated based on the humidity of the indoor environment corresponding to the air conditioner and the first speed can be understood as: the sum of the humidity of the indoor environment corresponding to the air conditioner and the first speed, or the weighted sum of the humidity of the indoor environment corresponding to the air conditioner and the first speed, or the difference between the humidity of the indoor environment corresponding to the air conditioner and the first speed, or the weighted difference between the humidity of the indoor environment corresponding to the air conditioner and the first speed, wherein the weight can be determined according to the target parameters, that is, the weight can correspond to the target parameters one-to-one, and the target parameters can include at least one of the parameters such as location, season, climate and temperature.

[0049] The third threshold value may be different from the first threshold value and the second threshold value, or the third threshold value may be calculated based on the first threshold value and the second threshold value, which is not specifically limited here.

[0050] It should be noted that when the energy in the air conditioner is constant, the speed of the cooling fan is adjusted from the first speed to the second speed, that is, when the speed of the cooling fan is reduced, the temperature of the air outlet of the air conditioner is reduced, which makes it easier for water vapor in the indoor environment to reach the dew point and be discharged to the outside through the drainage pipe of the air conditioner, thereby enhancing the dehumidification capacity of the air conditioner.

[0051] It should be noted that there is a balance between the sensible heat capacity and latent heat capacity of the air conditioner, which can be understood as the sum of the sensible heat capacity and the latent heat capacity being a fixed value. When the sensible heat capacity of the air conditioner is high, the cooling effect of the air conditioner is good, and when the latent heat capacity of the air conditioner is low, the dehumidification effect of the air conditioner is poor; when the sensible heat capacity of the air conditioner is low, the cooling effect of the air conditioner is poor, and when the latent heat capacity of the air conditioner is high, the dehumidification effect of the air conditioner is good. In this way, by reducing the speed of the cooling fan, the sensible heat capacity of the air conditioner is reduced to enhance the latent heat capacity of the air conditioner, thereby enhancing the dehumidification performance of the air conditioner.

[0052] It should be noted that the specific method of adjusting the rotation speed of the cooling fan from the first rotation speed to the second rotation speed is not limited here.

[0053] As an optional implementation manner, adjusting the rotation speed of the cooling fan from the first rotation speed to the second rotation speed includes:

[0054] Calculating a difference between the first rotational speed and a preset rotational speed;

[0055] determining the difference as the second speed;

[0056] The rotation speed of the cooling fan is adjusted from the first rotation speed to the second rotation speed.

[0057] In an implementation manner of the present application, the difference between the first speed and the preset speed can be calculated first, and the difference can be determined as the second speed, and then the speed of the cooling fan can be adjusted from the first speed to the second speed. In this way, the calculation result of the second speed can be highly accurate and the calculation method is simple.

[0058] The preset rotation speed may be a fixed value, or the preset rotation speed may be a variable value.

[0059] As an optional implementation manner, the preset rotation speed corresponds to the humidity of the indoor environment in a one-to-one manner, and the greater the humidity of the indoor environment, the greater the preset rotation speed.

[0060] In the implementation manner of the present application, when the humidity of the indoor environment is higher, it means that the dehumidification requirement is more urgent at this time. Therefore, the preset speed can be made larger, that is, the second speed is lower, so as to maximize the dehumidification capacity of the air conditioner; when the humidity of the indoor environment is lower, the preset speed is smaller, which means that the dehumidification requirement is less urgent at this time. Therefore, the preset speed can be made smaller, that is, the second speed is larger, so as to ensure that the dehumidification capacity and cooling capacity of the air conditioner are more balanced.

[0061] It should be noted that the corresponding relationship between the preset rotation speed and the humidity of the indoor environment may be a positive proportional relationship, or may be a positive correlation relationship, which is not specifically limited.

[0062] As an optional implementation manner, after adjusting the rotation speed of the cooling fan from the first rotation speed to the second rotation speed, the method further includes:

[0063] Obtaining the humidity of the indoor environment corresponding to the air conditioner;

[0064] When the humidity of the indoor environment corresponding to the air conditioner is less than a fourth threshold, the rotation speed of the cooling fan is adjusted from the second rotation speed to a third rotation speed, and the third rotation speed is greater than or equal to the first rotation speed.

[0065] The fourth threshold may be less than or equal to the first threshold.

[0066] In the implementation manner of the present application, when the humidity of the indoor environment corresponding to the air conditioner is less than the fourth threshold, it means that the dehumidification purpose of the indoor environment has been achieved, and the speed of the cooling fan can be increased to enhance the cooling capacity of the air conditioner.

[0067] It should be noted that, through the above implementation, a dynamic balance can be achieved between the dehumidification capacity and the cooling capacity of the air conditioner. In addition, the embodiment of the present application can dynamically adjust the dehumidification capacity and the cooling capacity of the air conditioner without adding a heat exchanger to the air conditioner, thereby increasing the intelligence of the air conditioner and reducing the cost of use.

[0068] As an optional implementation, the method further includes:

[0069] When at least one of the target conditions is met, maintaining the rotation speed of the cooling fan at the first rotation speed;

[0070] The target conditions include: the humidity of the indoor environment corresponding to the air conditioner is less than or equal to a first threshold, and the first rotation speed of the cooling fan of the air conditioner is less than or equal to a second threshold.

[0071] In the implementation mode of the present application, when at least one of the target conditions is met, it means that the dehumidification requirement of the indoor environment is not urgent at this time, or the wind speed of the cooling fan is low. At this time, there is no need to reduce the speed of the cooling fan, thereby avoiding the phenomenon that reducing the speed of the cooling fan causes the temperature of the indoor environment to drop slowly.

[0072] The above embodiment is fully described below with a specific embodiment.

[0073] See also Figure 2 ,like Figure 2As shown, when the air conditioner is turned on and in cooling mode, the humidity of the indoor environment corresponding to the air conditioner and the speed of the cooling fan of the air conditioner can be detected. When the humidity of the indoor environment is greater than B and the speed of the cooling fan of the air conditioner is greater than the second threshold, the speed of the cooling fan is reduced; when it is detected that the humidity of the indoor environment is less than A, the speed of the cooling fan can be restored, as shown in FIG. Figure 2 As shown, B is greater than A, and the cooling fan can be called an indoor fan, the humidity of the indoor environment can be called the indoor temperature, and during the speed adjustment of the cooling fan, the speed of the compressor can be maintained unchanged.

[0083] A second acquisition module is used to acquire the humidity of the indoor environment corresponding to the air conditioner;
