[0038] 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.

[0039] In the embodiments of the present disclosure, the terminal device refers to an electronic device with a wireless connection function.

Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, etc., or any combination thereof, wherein wearable devices include, for example: smart watches, smart bracelets, pedometers, etc.

[0040] In this embodiment, combined with Figure 1-1 to Figure 1-3 As shown, the cabinet air conditioner includes an indoor heat exchanger, an outdoor condenser 5, a compressor 4 and a four-way reversing valve 6, multiple throttling devices, a heat storage module 8, an air supply module, etc. Specifically, the dual air supply system of the cabinet air conditioner is composed of 2 motors, 2 fans, and 2 sets of air guides. Among them, the first indoor air supply module 71 and the second indoor air supply module 72 are independently controlled and operated, and the indoor heat exchanger is composed of a first indoor evaporator 31 and a second indoor evaporator 32 in parallel. The first indoor evaporator 31 and the second indoor evaporator 32 are respectively provided with a second throttling device 112 and a third throttling device 113 in front of the inlet. The cabinet air conditioner can realize the differentiated control of cooling and heating in the same space area and at the same time by independently controlling the inlet flow of the first indoor evaporator 31 and the second indoor evaporator 32.

[0041] Figure 1-1 This is a schematic diagram of a cabinet air conditioner heating and defrosting cycle provided by an embodiment of the present disclosure; Figure 1-1As shown, optionally, when the cabinet air conditioner is running in defrost mode, the cabinet air conditioner will close the second throttling device 112 or the third throttling device 113 under the premise of running in heating mode, and at the same time open the first throttling device 111 on the outdoor side 1, so that the high-temperature refrigerant compressed from the compressor 4 only flows through one indoor evaporator, reducing the consumption of the high-temperature refrigerant on the indoor side 2, and effectively increasing the residual heat of the outdoor condenser 5 for defrosting; at the same time, the fourth throttling device 114 located at the exhaust pipe of the compressor 4 and the fifth throttling device 115 located at the outlet are opened, so that the bypass refrigerant flows through the heat storage module 8 and then merges into the main exhaust pipe to participate in the circulation. At this time, the heat storage module 8 can perform heat storage operation, and the refrigerant participates in defrosting and flows out from the outdoor heat exchanger (outdoor condenser) 5, and the stop valve 9 is controlled to be closed, and the sixth throttling device 116 and the seventh throttling device 117 are started at the same time, so that the refrigerant flows into the heat storage module 8 to absorb the heat of the heat storage module 8 and evaporate back to the return air port of the compressor 4, thereby forming a heating and defrosting circuit.

[0042] Figure 1-2 is a schematic diagram of a cabinet air conditioner refrigeration cycle provided by an embodiment of the present disclosure; Figure 1-2 As shown, when the cabinet air conditioner is operating in the cooling mode, the refrigerant is compressed into a high-temperature and high-pressure gas after passing through the compressor 4. The high-temperature and high-pressure gaseous refrigerant transfers heat to the outside through the outdoor condenser 5 and becomes a low-temperature and low-pressure liquid refrigerant. The liquid refrigerant enters the indoor side 2 after throttling and reducing the pressure through the throttling device. The cabinet air conditioner automatically controls the opening of the second throttling device 112 and the third throttling device 113 according to user needs, thereby realizing differentiated heat exchange requirements.

[0043] Figure 1-3 is a schematic diagram of a cabinet air conditioner heating cycle provided by an embodiment of the present disclosure; Figure 1-3 As shown, when the cabinet air conditioner is in heating mode, the low-temperature and low-pressure gaseous refrigerant is compressed into high-temperature and high-pressure gas by the compressor 4, and the high-temperature and high-pressure gaseous refrigerant enters the first indoor evaporator 31 and / or the second indoor evaporator 32 on the indoor side 2; wherein, the cabinet air conditioner can automatically control the opening of the second throttling device 112 and the third throttling device 113 according to user needs, thereby achieving differentiated heat exchange requirements by adjusting the refrigerant flow. Among them, when the cabinet air conditioner is in heating mode, the cabinet air conditioner closes the fourth throttling device 114, the fifth throttling device 115, the sixth throttling device 116 and the seventh throttling device 117 on the outdoor side, and opens the first throttling device 111, the second throttling device 112 and the third throttling device 113, and opens the stop valve 9.

[0044] Figure 2 is a schematic diagram of a method for controlling a cabinet air conditioner provided by an embodiment of the present disclosure; Figure 2 As shown, optionally, the embodiment of the present disclosure provides a method for controlling a cabinet air conditioner, comprising:

[0045] S21, the cabinet air conditioner obtains the ambient temperature of the outdoor area where the cabinet air conditioner is located, the heating amount of the cabinet air conditioner, and the operating time of the cabinet air conditioner compressor.

[0046] S22, when the ambient temperature outside the cabinet air conditioner, the heating amount of the cabinet air conditioner, and the running time of the cabinet air conditioner compressor all meet the defrost start conditions, the cabinet air conditioner determines a target defrost strategy for the cabinet air conditioner.

[0047] S23, the cabinet air conditioner controls the cabinet air conditioner to execute a target defrost strategy in a defrost mode.

[0048] In this solution, the cabinet air conditioner can collect the ambient temperature outdoors where it is located through its associated outdoor temperature sensor. The cabinet air conditioner obtains the heating capacity of the cabinet air conditioner, including: the cabinet air conditioner obtains the real-time coil temperature of the cabinet air conditioner and the ambient temperature of the room where the cabinet air conditioner is located; the cabinet air conditioner uses the difference between the real-time coil temperature and the ambient temperature of the room where the cabinet air conditioner is located as the heating capacity of the cabinet air conditioner. The cabinet air conditioner can also calculate the operating time of the cabinet air conditioner compressor based on the start time of the compressor and the current time. In this way, the ambient temperature outdoors where the cabinet air conditioner is located, the heating capacity of the cabinet air conditioner, and the operating time of the cabinet air conditioner compressor can be accurately obtained.

[0049] Furthermore, the cabinet air conditioner can determine whether the defrost start condition is met in the following manner: the cabinet air conditioner takes the quotient of the heating amount of the cabinet air conditioner and the heat reference value as the first ratio; when the ambient temperature outside the cabinet air conditioner is lower than the target temperature threshold, the first ratio is not higher than the first threshold, and the running time of the cabinet air conditioner compressor is greater than the target time threshold, the cabinet air conditioner determines that the ambient temperature outside the cabinet air conditioner, the heating amount of the cabinet air conditioner, and the running time of the cabinet air conditioner compressor all meet the defrost start condition. In this way, the cabinet air conditioner can determine the target defrost strategy of the cabinet air conditioner when the ambient temperature outside the cabinet air conditioner, the heating amount of the cabinet air conditioner, and the running time of the cabinet air conditioner compressor all meet the defrost start condition. Here, the target defrost strategy includes a micro-frost processing strategy or a thick frost processing strategy. After determining the target defrost strategy of the cabinet air conditioner, the cabinet air conditioner can control the cabinet air conditioner to execute the target defrost strategy in the defrost mode.

[0050] The method for controlling the cabinet air conditioner provided by the embodiment of the present disclosure is adopted, by obtaining the outdoor ambient temperature of the cabinet air conditioner, the heating capacity of the cabinet air conditioner and the running time of the cabinet air conditioner compressor; and when the outdoor ambient temperature of the cabinet air conditioner, the heating capacity of the cabinet air conditioner and the running time of the cabinet air conditioner compressor meet the defrosting start conditions, the target defrosting strategy of the cabinet air conditioner is determined; thereby controlling the cabinet air conditioner to execute the target defrosting strategy in the defrosting mode. With this scheme, the defrosting efficiency of the cabinet air conditioner can be effectively improved when the cabinet air conditioner is controlled to execute the target defrosting strategy in the defrosting mode, and the situation of a sharp drop in indoor temperature when the cabinet air conditioner is defrosted is also improved, thereby improving the user experience of the cabinet air conditioner and the reliability of the cabinet air conditioner.

[0051] Figure 3 is a schematic diagram of a method for determining defrost start conditions provided by an embodiment of the present disclosure; Figure 3 As shown, optionally, the ambient temperature outside the cabinet air conditioner, the heating capacity of the cabinet air conditioner, and the running time of the cabinet air conditioner compressor all meet the defrost start condition in the following manner:

[0052] S31, the cabinet air conditioner takes the quotient of the heating amount of the cabinet air conditioner and the heat reference value as the first ratio.

[0053] S32, when the ambient temperature outdoors of the cabinet air conditioner is lower than the target temperature threshold, the first ratio is not higher than the first threshold, and the operating time of the cabinet air conditioner compressor is greater than the target time threshold, the cabinet air conditioner determines that the ambient temperature outdoors of the cabinet air conditioner, the heating amount of the cabinet air conditioner, and the operating time of the cabinet air conditioner compressor all meet the defrost start conditions.

[0054] In this solution, after the cabinet air conditioner obtains the heat reference value through calculation, the quotient of the heating capacity of the cabinet air conditioner and the heat reference value can be calculated to take it as the first ratio. And when the ambient temperature outside the cabinet air conditioner is lower than the target temperature threshold, the first ratio is not higher than the first threshold, and the running time of the cabinet air conditioner compressor is greater than the target time threshold, the cabinet air conditioner determines that the ambient temperature outside the cabinet air conditioner, the heating capacity of the cabinet air conditioner and the running time of the cabinet air conditioner compressor all meet the defrost start conditions. Among them, the target temperature threshold is the initial ambient temperature of frost at the location of the cabinet air conditioner, the first threshold is 0.8, and the target time threshold is the time pre-set by the user for the cabinet air conditioner to not perform defrosting after starting. In this way, it is possible to accurately determine whether the defrost start conditions are met.

[0055] Figure 4 is a schematic diagram of a method for determining a target defrosting strategy provided by an embodiment of the present disclosure; Figure 4 As shown, optionally, in S22, the cabinet air conditioner determines a target defrosting strategy for the cabinet air conditioner, including:

[0056] S41, the cabinet air conditioner calculates a heat reference value according to a standard indoor coil temperature and a standard indoor ambient temperature of the cabinet air conditioner.

[0057] S42, the cabinet air conditioner takes the quotient of the heating amount of the cabinet air conditioner and the heat reference value as the first ratio.

[0058] S43, the cabinet air conditioner determines a target defrosting strategy for the cabinet air conditioner according to the first ratio.

[0059] In this solution, the cabinet air conditioner can obtain the standard indoor coil temperature and standard indoor ambient temperature of the cabinet air conditioner. Here, the standard indoor coil temperature of the cabinet air conditioner is the average value of the coil temperature of the cabinet air conditioner for five consecutive cycles in an unfrosted state. As an example, each cycle is 1 minute. The standard indoor ambient temperature is the average value of the indoor ambient temperature of the cabinet air conditioner for five consecutive cycles in an unfrosted state. In this way, after the cabinet air conditioner obtains the standard indoor coil temperature and standard indoor ambient temperature of the cabinet air conditioner, the difference between the standard indoor coil temperature and the standard indoor ambient temperature can be used as a heat reference value. In this way, the heat reference value can be accurately calculated.

[0060] Furthermore, the cabinet air conditioner can use the quotient of the calculated heating amount of the cabinet air conditioner and the heat reference value as the first ratio. Thereby, the target defrost strategy of the cabinet air conditioner is determined in combination with the first ratio. Specifically, the cabinet air conditioner determines the target defrost strategy of the cabinet air conditioner according to the first ratio, including: when the first ratio is not higher than the first threshold value and higher than the second threshold value, the cabinet air conditioner determines that the target defrost strategy of the cabinet air conditioner is a light frost processing strategy. When the first ratio is lower than the second threshold value, the cabinet air conditioner determines that the target defrost strategy of the cabinet air conditioner is a thick frost processing strategy. In this way, the target defrost strategy can be accurately determined in combination with the calculated first ratio.

[0061] Optionally, in S43, the cabinet air conditioner determines a target defrosting strategy for the cabinet air conditioner according to the first ratio, including:

[0062] When the first ratio is not higher than the first threshold value and higher than the second threshold value, the cabinet air conditioner determines that the target defrost strategy of the cabinet air conditioner is the light frost processing strategy.

[0063] When the first ratio is lower than the second threshold, the cabinet air conditioner determines that the target defrost strategy of the cabinet air conditioner is a thick frost processing strategy.

[0064] In this solution, the first threshold is 0.8 and the second threshold is 0.6. In this way, when the first ratio is not higher than 0.8 and higher than 0.6, the target defrost strategy of the cabinet air conditioner can be determined as a light frost processing strategy; when the first ratio is lower than 0.6, the cabinet air conditioner determines the target defrost strategy of the cabinet air conditioner as a thick frost processing strategy. In this way, the target defrost strategy can be accurately determined in combination with the calculated first ratio.

[0065] Figure 5 is a schematic diagram of a microfrost treatment strategy according to an embodiment of the present disclosure; Figure 5 As shown, optionally, the micro-frost treatment strategy includes:

[0066] S51, the cabinet air conditioner determines a target air outlet farthest from a user among multiple air outlets.

[0067] S52, the cabinet air conditioner controls the cabinet air conditioner to close the air supply module and the throttling device inside the target air outlet.

[0068] S53, when the throttling device on the outdoor side of the cabinet air conditioner is turned on and it is determined that the light frost processing conditions are met, the cabinet air conditioner controls the air supply module on the inner side of the target air outlet to start again according to the low wind gear.

[0069] In this solution, the cabinet air conditioner can obtain the user's location information through the radar sensor and determine the target air outlet farthest from the user among multiple air outlets. Furthermore, the cabinet air conditioner controls the cabinet air conditioner to close the air supply module and throttling device inside the target air outlet. This makes it easier for the indoor side to enter the single evaporator heat exchange mode.

[0070] Furthermore, when the throttling device on the outdoor side of the cabinet air conditioner is turned on and it is determined that the light frost processing conditions are met, the cabinet air conditioner can control the air supply module inside the target air outlet according to the low wind gear to start again. As an example, if the cabinet air conditioner determines that less heat is currently required for defrosting, it is determined that it meets the light frost processing conditions. With this solution, it is possible to ensure rapid defrosting while starting the wind chasing mode of the cabinet air conditioner, thereby improving the user's comfort.

[0071] Optionally, thick frost management strategies include:

[0072] The cabinet air conditioner controls the cabinet air conditioner by closing the throttling device inside any air outlet and at the same time closing the air supply modules arranged inside each air outlet.

[0073] In this solution, the cabinet air conditioner can control the cabinet air conditioner to close the throttling device inside any air outlet and close the air supply module set inside each air outlet. In this way, the heat exchanger does not absorb indoor heat and transfers higher heat to the outside to quickly defrost the outdoor unit of the cabinet air conditioner.

[0074] Figure 6 is another schematic diagram of a method for controlling a cabinet air conditioner provided by an embodiment of the present disclosure; Figure 6 As shown, optionally, after the cabinet air conditioner is controlled to execute the target defrost strategy in the defrost mode, it also includes:

[0075] S61, the cabinet air conditioner obtains the execution time of the air conditioner executing the target defrost strategy and the quotient of the current heating capacity of the cabinet air conditioner and the heating reference value;

[0076] S62, when the execution time is greater than the preset time threshold and / or the quotient of the current heating amount of the cabinet air conditioner and the heat reference value is greater than the first threshold, the cabinet air conditioner controls the cabinet air conditioner to stop running the defrost mode and stop executing the target defrost strategy.

[0077] In this solution, the cabinet air conditioner can obtain the current heating capacity of the cabinet air conditioner and calculate the quotient of the current heating capacity of the cabinet air conditioner and the heat reference value. In addition, the cabinet air conditioner can also obtain the execution time of the air conditioner executing the target defrost strategy through its associated timing module. In this way, accurate data acquisition can be achieved.

[0078] Furthermore, when the execution time is greater than the preset time threshold and / or the quotient of the current heating amount of the cabinet air conditioner and the heat reference value is greater than the first threshold, the cabinet air conditioner controls the cabinet air conditioner to stop running the defrost mode and stops executing the target defrost strategy. The preset time threshold is the defrost limit time pre-set by the user, and the first threshold is 0.8. In this way, the stop timing of the target defrost strategy is accurately determined, providing an accurate data basis for the energy-saving control of the cabinet air conditioner.

[0079] Figure 7 is a schematic diagram of a device for controlling a cabinet air conditioner provided by an embodiment of the present disclosure; Figure 7 As shown, the embodiment of the present disclosure provides a device 200 for controlling a cabinet air conditioner, including an acquisition module 71, a determination module 72 and a control module 73. The acquisition module 71 is configured to acquire the ambient temperature outside the cabinet air conditioner, the heating capacity of the cabinet air conditioner and the running time of the cabinet air conditioner compressor; the determination module 72 is configured to determine the target defrost strategy of the cabinet air conditioner when the ambient temperature outside the cabinet air conditioner, the heating capacity of the cabinet air conditioner and the running time of the cabinet air conditioner compressor meet the defrost start condition; the control module 73 is configured to execute the target defrost strategy for the cabinet air conditioner in the defrost mode.

[0080] The device 200 for controlling the cabinet air conditioner provided by the embodiment of the present disclosure is adopted, by obtaining the ambient temperature outside the cabinet air conditioner, the heating capacity of the cabinet air conditioner, and the operating time of the cabinet air conditioner compressor; and when the ambient temperature outside the cabinet air conditioner, the heating capacity of the cabinet air conditioner, and the operating time of the cabinet air conditioner compressor all meet the defrosting start conditions, the target defrosting strategy of the cabinet air conditioner is determined; thereby controlling the cabinet air conditioner to execute the target defrosting strategy in the defrosting mode. With this scheme, the defrosting efficiency of the cabinet air conditioner can be effectively improved when the cabinet air conditioner is controlled to execute the target defrosting strategy in the defrosting mode, and the situation of a sharp drop in indoor temperature when the cabinet air conditioner is defrosted is also improved, thereby improving the user experience of the cabinet air conditioner and the reliability of the cabinet air conditioner.
