[0032] In the embodiments of the present disclosure, smart home appliances refer to home appliances that are formed by introducing microprocessors, sensor technology, and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent perception, and intelligent application. The operation process of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage the smart home appliances.

[0034] Figure 1 is a schematic diagram of a method for controlling an air conditioner provided by an embodiment of the present disclosure; Figure 1 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0035] S11, when it is determined that the air conditioner operates in a cooling mode, the air conditioner obtains the ambient humidity of the room where the air conditioner is located.

[0036] S12: When the ambient humidity is not lower than a first humidity threshold, the air conditioner determines a dehumidification strategy for the room where the air conditioner is located.

[0037] S13, controlling the air conditioner to execute a dehumidification strategy to reduce the ambient humidity in the room where the air conditioner is located.

[0038] In this solution, the air conditioner can obtain its current operating mode. As an example, the air conditioner can obtain its current operating information, and determine the operating mode represented by the current operating information as the current operating mode of the air conditioner. In another example, the air conditioner can also obtain the display information of its associated remote control device, and extract the operating mode of the air conditioner from the display information to determine it as the current operating mode of the air conditioner. In this way, accurate acquisition of the operating mode of the air conditioner can be achieved. Furthermore, when it is determined that the air conditioner is operating in a cooling mode, the air conditioner can obtain the ambient humidity in the room where the air conditioner is located. Here, the air conditioner can obtain the ambient humidity through its associated ambient humidity sensor. Specifically, the layout position of the ambient humidity sensor can be determined by the specific conditions of the house.

[0039] As an optimized solution, in order to more accurately obtain the ambient humidity in the room where the air conditioner is located, multiple ambient humidity sensors can be arranged in the room where the air conditioner is located, and the average of the ambient humidity values ​​collected by the multiple ambient humidity sensors is determined as the ambient humidity in the room where the air conditioner is located. In this way, the accuracy of obtaining the ambient humidity in the room where the air conditioner is located is guaranteed.

[0040] Further, after the air conditioner obtains the ambient humidity in the room where the air conditioner is located, the ambient humidity in the room where the air conditioner is located can be compared with the first humidity threshold, and when the ambient humidity is not lower than the first humidity threshold, it is determined that the humidity in the room where the air conditioner is located is too high, which seriously affects the user's environmental comfort. As an example, the first humidity threshold is 80%. In this way, the dehumidification strategy in the room where the air conditioner is located can be determined when the ambient humidity is greater than or equal to 80%. Specifically, the air conditioner determines the dehumidification strategy in the room where the air conditioner is located, including: the air conditioner determines the target control strategy of the throttling device; the air conditioner determines the dehumidification strategy in the room where the air conditioner is located to control the air conditioner to run according to the set temperature and the set wind speed while controlling the throttling device to execute the target control strategy until the temperature at the middle position of the branch reaches the first target temperature. In this way, the dehumidification strategy can be accurately determined so that the dehumidification strategy determined in this way is more in line with the humidity characteristics of the indoor environment. Further, the air conditioner can control the air conditioner to execute the dehumidification strategy to quickly reduce the ambient humidity in the room where the air conditioner is located while lowering the temperature through the cooling mode.

[0041] The method for controlling an air conditioner provided by the embodiment of the present disclosure is adopted. When the air conditioner is determined to be in a cooling mode, the ambient humidity in the room where the air conditioner is located is obtained; when the ambient humidity is not lower than a first humidity threshold, the dehumidification strategy in the room where the air conditioner is located is determined; and the air conditioner is controlled to execute the dehumidification strategy to reduce the ambient humidity in the room where the air conditioner is located. With this solution, a more accurate dehumidification strategy can be determined for the current indoor humidity situation when the room is in a high temperature and high humidity environment, so that the air conditioner can be reasonably controlled to execute the dehumidification strategy during the process of the air conditioner operating in the cooling mode, and the indoor humidity value can be quickly reduced while the indoor temperature of the air conditioner is reduced, so that the user can quickly be in a comfortable temperature and humidity environment, meet the user's control requirements for the air conditioner, and further improve the user's experience of using the air conditioner.

[0042] Figure 2 is a schematic diagram of a method for determining a dehumidification strategy provided by an embodiment of the present disclosure; Figure 2 As shown, optionally, in S12, the air conditioner determines a dehumidification strategy for the room where the air conditioner is located, including:

[0043] S21, the air conditioner determines a target control strategy for the throttling device.

[0044] S22, the air conditioner determines that the dehumidification strategy for the room where the air conditioner is located is to control the air conditioner to operate according to the set temperature and set wind speed while controlling the throttling device to execute the target control strategy until the temperature at the middle position of the branch reaches the first target temperature.

[0045] In this solution, the indoor heat exchanger of the air conditioner includes multiple branches. As a preferred solution, the indoor heat exchanger of the air conditioner includes three refrigerant branches. Specifically, a throttling device is provided at the refrigerant inlet of any branch of the indoor heat exchanger of the air conditioner, i.e., the evaporator, and the air conditioner can adjust the refrigerant flow rate flowing into the branch by controlling the throttling device. Here, the throttling device can be an electronic expansion valve, and the air conditioner can adjust the refrigerant flow rate flowing into the branch by adjusting the opening of the electronic expansion valve. In this way, the air conditioner can determine the target control strategy of the throttling device. In this way, a precise data basis can be provided for the control of the throttling device.

[0046] Furthermore, the set temperature and set humidity are input into the air conditioner by the user in advance. As another example, the air conditioner can obtain its historical operation information, and extract the operating temperature and operating wind speed when the air conditioner is running from the historical operation information to use them as the set temperature and set humidity. In this way, the set temperature and set humidity can be accurately obtained.

[0047] In addition, the middle position of the branch refers to the position of the temperature sensor that can detect the phase change temperature of the refrigerant flowing into the branch. It should be noted that the middle position of the branch is the layout position obtained by the R&D personnel after experiments. If the phase change temperature of the refrigerant can also be detected at other positions in the branch, the temperature sensor can also be arranged at other positions, which is not specifically limited here. As an example, the value range of the first target temperature is -4°C to -3°C. As a preferred solution, the first target temperature can be determined as -3°C. In this way, the dehumidification strategy in the room where the air conditioner is located can be determined to control the air conditioner to run according to the set temperature and set wind speed while controlling the throttling device to execute the target control strategy until the temperature at the middle position of the branch (the phase change temperature of the refrigerant) reaches -3°C. In this way, the precise determination of the dehumidification strategy in the room where the air conditioner is located can be achieved.

[0048] Figure 3 is a schematic diagram of a method for determining a target control strategy provided by an embodiment of the present disclosure; Figure 3 As shown, optionally, in S21, the air conditioner determines a target control strategy for the throttling device, including:

[0049] S31, the air conditioner obtains a temperature value collected by a temperature sensor.

[0050] S32, the air conditioner determines a target adjustment rate of the electronic expansion valve according to the temperature value.

[0051] S33, the air conditioner determines that the target control strategy of the throttling device is to control the electronic expansion valve to close according to the target adjustment rate.

[0052] In this solution, any branch can be a refrigerant branch below the indoor heat exchanger. A temperature sensor is provided in the middle of any branch, and the temperature sensor can detect the phase change temperature of the refrigerant flowing into the branch. The throttling device is an electronic expansion valve. In this way, the air conditioner can obtain the temperature value collected by the temperature sensor. In this way, the phase change temperature of the refrigerant flowing into the branch can be accurately obtained.

[0053] Further, the air conditioner determines the target adjustment rate of the electronic expansion valve according to the temperature value, including: when the temperature value is greater than the first temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve to be the first rate. When the temperature value is greater than the second temperature threshold and less than the first temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve to be the second rate. When the temperature value is greater than the third temperature threshold and less than the second temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve to be the third rate. In this way, the target adjustment rate of the electronic expansion valve can be accurately determined in combination with the phase change temperature of the refrigerant flowing into the branch.

[0054] Furthermore, the air conditioner can determine the target control strategy of the throttling device to control the electronic expansion valve to close according to the target adjustment rate. In this way, the target control strategy can be accurately determined, providing an accurate data basis for the control of the electronic expansion valve, so that the branch can be frosted more accurately under the premise of controlling the electronic expansion valve in this way.

[0055] Optionally, in S32, the air conditioner determines a target adjustment rate of the electronic expansion valve according to the temperature value, including:

[0056] When the temperature value is greater than the first temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve to be the first rate.

[0057] When the temperature value is greater than the second temperature threshold and less than the first temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve to be the second rate.

[0058] When the temperature value is greater than the third temperature threshold and less than the second temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve to be the third rate.

[0059] In this solution, the first rate>the second rate>the third rate. As an example, the first rate is 3 steps / second, the second rate is 1 step / second, the third rate is 0.5 steps / second, the first temperature threshold is 2°C, the second temperature threshold is 0°C, and the third temperature threshold is -3°C. In this way, when the temperature value is greater than 2°C, the air conditioner determines the target adjustment rate of the electronic expansion valve to be 3 steps / second; when the temperature value is greater than 0°C and less than 2°C, the air conditioner determines the target adjustment rate of the electronic expansion valve to be 1 step / second; when the temperature value is greater than -3°C and less than 0°C, the air conditioner determines the target adjustment rate of the electronic expansion valve to be 0.5 steps / second. In this way, the target adjustment rate can be accurately determined in combination with the temperature value, providing an accurate data basis for the control of the electronic expansion valve.

[0060] Optionally, after controlling the air conditioner to execute the dehumidification strategy, the method further includes:

[0061] After the preset time, the air conditioner controls the air conditioner to open the electronic expansion valve at a fourth rate until the opening of the electronic expansion valve reaches the target opening.

[0062] In this solution, the preset time is 5 minutes, so the air conditioner can control the air conditioner to open the electronic expansion valve at the fourth rate after controlling it to execute the dehumidification strategy for 5 minutes. Here, the fourth rate>the first rate. As an example, the fourth rate is 10 steps / second. The target opening is the maximum opening of the electronic expansion valve. For example, the target opening is 300 steps. With this solution, the electronic expansion valve can be adjusted to the maximum opening at the fastest speed to allow the refrigerant to quickly flow into the branch, so as to quickly defrost and discharge condensed water, so that when the air conditioner is running in cooling mode, the indoor humidity can be quickly reduced while ensuring indoor temperature regulation, providing users with a more comfortable indoor temperature and humidity environment.

[0063] Optionally, when the ambient humidity is greater than the second humidity threshold and lower than the first humidity threshold, the air conditioner controls the air conditioner to operate according to the set temperature and set wind speed.

[0064] In this solution, the second temperature threshold is 50%. When the ambient humidity is greater than 50% and less than 80%, it can be determined that the current ambient humidity is relatively comfortable. The air conditioner can be controlled to operate according to the set temperature and set wind speed in the cooling mode, so that the indoor temperature can be accurately adjusted when the humidity meets the user's comfort requirements.

[0065] Optionally, when the ambient humidity is not greater than a second humidity threshold, the air conditioner controls the air conditioner to operate according to a set temperature and a set wind speed; when the temperature value collected by the temperature sensor is lower than a second target temperature, the air conditioner controls the air conditioner to turn off the throttling device.

[0066] In this solution, when the ambient humidity is less than or equal to 50%, the air conditioner controls itself to run according to the set temperature and set wind speed; further, the air conditioner can obtain the temperature value collected by the temperature sensor, and when the temperature value collected by the temperature sensor is lower than the second target temperature, the air conditioner controls the air conditioner to close the throttling device. Here, the second target temperature value is determined in the following way: second target temperature value = return air temperature of the air conditioning compressor - reference value. As an example, the reference value is 3°C. In this way, the closing time of the throttling device is accurately determined, so that when the air conditioner is controlled to close the throttling device, the branch is in an overheated state and no condensation water is formed, thereby making the indoor environmental humidity value more stable, avoiding the discomfort caused to users by low indoor humidity values.

With this solution, when the air conditioner is in a cooling mode and the ambient humidity is not lower than the first humidity threshold, a more accurate dehumidification strategy can be determined for the current indoor humidity situation, so that when the air conditioner is reasonably controlled to execute the dehumidification strategy, the indoor humidity value can be quickly reduced while reducing the indoor temperature of the room where the air conditioner is located, so that the user can quickly be in a comfortable temperature and humidity environment, meet the user's control requirements for the air conditioner, and further improve the user's experience of using the air conditioner.
