[0032] In the embodiments of the present disclosure, the smart home appliance refers to the home appliance product formed after introducing microprocessors, sensor technology, network communication technology into home appliances, with the characteristics of intelligent control, intelligent perception and intelligent application.

[0033] In the embodiments of the present disclosure, the terminal device refers to an electronic device with a wireless connection function. The terminal device can be connected to the smart home appliance through the Internet, or can be directly connected to the smart home appliance through Bluetooth, WiFi, etc. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a built-in vehicle device of a hovercar, or any combination thereof.

[0034] Figure 1 is a schematic diagram of a method for controlling an air conditioner provided by the embodiments of the present disclosure; in combination with Figure 1 As shown in the figure, the embodiments of the present disclosure provide a method for controlling an air conditioner, which includes the following steps.

[0035] S11, in the case of determining that the air conditioner operates in a cooling mode, the air conditioner acquires the environmental humidity of the indoor room where the air conditioner is located.

[0036] S12, in the case of the environmental humidity being not lower than a first humidity threshold, the air conditioner determines a dehumidification strategy of the indoor room where the air conditioner is located.

[0037] S13, the air conditioner is controlled to execute the dehumidification strategy to reduce the environmental humidity of the indoor room where the air conditioner is located.

[0038] In the present scheme, the air conditioner can acquire its current operating mode. As an example, the air conditioner can acquire its current operating information and determine the operating mode indicated by the current operating information as the current operating mode of the air conditioner. In another example, the air conditioner can also acquire the display information of the remote control device associated therewith 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. Further, in the case of determining that the air conditioner operates in a cooling mode, the air conditioner can acquire the environmental humidity of the indoor room where the air conditioner is located. Here, the air conditioner can acquire the environmental humidity through the environmental humidity sensor associated therewith. Specifically, the arrangement position of the environmental humidity sensor can be determined by the specific situation of the house.

[0039] As an optimized scheme, in order to more accurately acquire the environmental humidity of the indoor room where the air conditioner is located, a plurality of environmental humidity sensors can also be arranged in the indoor room where the air conditioner is located, and the average of the environmental humidity values collected by the plurality of environmental humidity sensors is determined as the environmental humidity of the indoor room where the air conditioner is located. In this way, the accuracy of the acquisition of the environmental humidity of the indoor room where the air conditioner is located is ensured.

[0040] Further, after the air conditioner obtains the environmental humidity of the indoor environment where the air conditioner is located, the environmental humidity of the indoor environment where the air conditioner is located can be compared with the first humidity threshold value, and in the case that the environmental humidity is not lower than the first humidity threshold value, it is determined that the humidity of the indoor environment where the air conditioner is located is too large, which seriously affects the environmental comfort of the user. As an example, the first humidity threshold value is 80%. In this way, in the case that the environmental humidity is greater than or equal to 80%, the dehumidification strategy of the indoor environment where the air conditioner is located can be determined. Specifically, the air conditioner determines the dehumidification strategy of the indoor environment where the air conditioner is located, including: the air conditioner determines the target control strategy of the throttling device; the air conditioner determines that the dehumidification strategy of the indoor environment where the air conditioner is located is to control the throttling device to execute the target control strategy while controlling the air conditioner to operate according to the set temperature and the set air speed, until the temperature at the middle position of the branch reaches the first target temperature. In this way, the accurate determination of the dehumidification strategy can be realized, 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 environmental humidity of the indoor environment where the air conditioner is located while reducing the temperature by the refrigeration mode.

[0041] By adopting the method for controlling the air conditioner provided in the embodiments of the present disclosure, in the case that the air conditioner operates in the refrigeration mode, the environmental humidity of the indoor environment where the air conditioner is located is obtained; in the case that the environmental humidity is not lower than the first humidity threshold value, the dehumidification strategy of the indoor environment where the air conditioner is located is determined; and the air conditioner is controlled to execute the dehumidification strategy to reduce the environmental humidity of the indoor environment where the air conditioner is located. With this scheme, in the case that the indoor environment is in a high-temperature and high-humidity environment, a more accurate dehumidification strategy can be determined according to the current humidity of the indoor environment, so that the air conditioner is reasonably controlled to execute the dehumidification strategy in the process of operating in the refrigeration mode, the humidity value of the indoor environment is quickly reduced while the temperature of the indoor environment where the air conditioner is located is reduced, which is convenient for the user to quickly be in a comfortable temperature and humidity environment, meets the control demand of the user on the air conditioner, and further improves the user experience of using the air conditioner.

[0042] Figure 2 is a schematic diagram of a method for determining a dehumidification strategy provided in the embodiments of the present disclosure; in combination with Figure 2 as shown, optionally, S12, the air conditioner determines the dehumidification strategy of the indoor environment where the air conditioner is located, including:

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

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

[0045] In the present solution, the indoor heat exchanger of the air conditioner comprises a plurality of branches. As a preferred solution, the indoor heat exchanger of the air conditioner comprises three refrigerant branches. Specifically, a throttling device is arranged at the refrigerant inlet of any branch of the indoor heat exchanger, i.e., the evaporator, and the air conditioner can adjust the refrigerant flow 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 into the branch by adjusting the opening degree of the electronic expansion valve. In this way, the air conditioner can determine the target control strategy of the throttling device. In this way, accurate data basis can be provided for the control of the throttling device.

[0046] Further, the set temperature and the set humidity are input by the user into the air conditioner in advance. As another example, the air conditioner can obtain its historical operation information, and extract the operation temperature and the operation air speed when the air conditioner is running in the historical operation information, as the set temperature and the set humidity. In this way, accurate acquisition of the set temperature and the set humidity can be achieved.

[0047] In addition, the middle position of the branch refers to the arrangement position of the temperature sensor capable of detecting the phase change temperature of the refrigerant flowing into the branch. It should be noted that the middle position of the branch is the arrangement position obtained by the researchers after experiments, and if the phase change temperature of the refrigerant can also be detected at other positions of the branch, the temperature sensor can also be arranged at the other positions, which is not specifically limited here. As an example, the first target temperature is in the range of -4℃ to -3℃. As a preferred solution, the first target temperature can be determined as -3℃. In this way, the dehumidification strategy of the indoor space where the air conditioner is located can be determined as controlling the air conditioner to run according to the set temperature and the set air speed while controlling the throttling device to perform the target control strategy until the temperature at the middle position of the branch (the phase change temperature of the refrigerant) reaches -3℃. In this way, accurate determination of the dehumidification strategy of the indoor space 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; in combination with Figure 3 As shown in FIG. 7, optionally, S21, the air conditioner determines a target control strategy of the throttling device, comprising:

[0049] S31, the air conditioner acquires the temperature value collected by the 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 at the target adjustment rate.

[0052] In the scheme, any branch can be a refrigerant branch below the indoor heat exchanger. A temperature sensor is arranged at a middle position of any branch, which 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: in the case that the temperature value is greater than a first temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve as a first rate. In the case that the temperature value is greater than a second temperature threshold and less than the first temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve as a second rate. In the case that the temperature value is greater than a third temperature threshold and less than the second temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve as a 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] Further, the air conditioner can determine the target control strategy of the throttling device as controlling the electronic expansion valve to close at the target adjustment rate. In this way, the accurate determination of the target control strategy can be realized, and accurate data basis is provided for the control of the electronic expansion valve, so as to more accurately cause the branch to frost in the premise of controlling the electronic expansion valve in this way.

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

[0056] In the case that the temperature value is greater than a first temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve as a first rate.

[0057] In the case that the temperature value is greater than a second temperature threshold and less than the first temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve as a second rate.

[0058] In the case that the temperature value is greater than a third temperature threshold and less than the second temperature threshold, the air conditioner determines the target adjustment rate of the electronic expansion valve as a third rate.

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

[0060] Optionally, after the air conditioner is controlled to execute the dehumidification strategy, the method further comprises:

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

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

[0063] Optionally, when the environmental humidity is greater than the second humidity threshold and less than the first humidity threshold, the air conditioner controls the air conditioner to run at the set temperature and the set wind speed.

[0064] In the present solution, the second temperature threshold is 50%, and when the environmental humidity is greater than 50% and less than 80%, it is determined that the current environmental humidity is comfortable, and the air conditioner can be controlled to run at the set temperature and the set wind speed in the cooling mode, so as to accurately regulate the indoor temperature when the humidity meets the user's comfort requirement.

[0065] Optionally, when the environmental humidity is not greater than the second humidity threshold, the air conditioner controls the air conditioner to run at the set temperature and the set wind speed; 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.

[0066] In the scheme, the air conditioner controls it to run according to the set temperature and the set wind speed in the case of the environmental humidity being less than or equal to 50%; further, the air conditioner can obtain the temperature value collected by the temperature sensor, and controls the air conditioner to close the throttling device in the case of the temperature value collected by the temperature sensor being lower than the second target temperature. Here, the second target temperature value is determined by the following manner: the second target temperature value = the return air temperature of the compressor of the air conditioner - the reference amount. As an example, the reference amount is 3℃. In this way, the closing time of the throttling device is accurately determined, so that the branch is in an overheating state in the case of controlling the air conditioner to close the throttling device, and the condensed water is no longer formed, so that the indoor environmental humidity value is more stable, and the discomfort of the user caused by the low indoor humidity value is avoided.

[0067] Figure 4 is a schematic diagram of an apparatus for controlling an air conditioner provided by an embodiment of the present disclosure; in combination with Figure 4 As shown in the figure, the apparatus for controlling an air conditioner provided by an embodiment of the present disclosure comprises an obtaining module 41, a determining module 42 and a controlling module 43. The obtaining module 41 is configured to obtain the environmental humidity in the indoor room where the air conditioner is located in the case of determining that the air conditioner runs in a cooling mode. The determining module 42 is configured to determine the dehumidification strategy of the indoor room where the air conditioner is located in the case of the environmental humidity not being lower than a first humidity threshold. The controlling module 43 is configured to control the air conditioner to execute the dehumidification strategy to reduce the environmental humidity in the indoor room where the air conditioner is located.

[0068] By using the apparatus for controlling an air conditioner provided by the present disclosure, the environmental humidity in the indoor room where the air conditioner is located is obtained in the case of determining that the air conditioner runs in a cooling mode; the dehumidification strategy of the indoor room where the air conditioner is located is determined in the case of the environmental humidity not being lower than a first humidity threshold; and the air conditioner is controlled to execute the dehumidification strategy to reduce the environmental humidity in the indoor room where the air conditioner is located. In this scheme, in the case of the air conditioner running in a cooling mode and the environmental humidity not being lower than a first humidity threshold, a more accurate dehumidification strategy can be determined according to the humidity condition of the current indoor room, so that the indoor humidity value is quickly reduced while the temperature in the indoor room is reduced in the case of reasonably controlling the air conditioner to execute the dehumidification strategy, which facilitates the user to quickly be in a comfortable temperature and humidity environment, meets the control demand of the user on the air conditioner, and further improves the use experience of the user on the air conditioner.
