Smart appliances are more than just simple household appliances; they integrate advanced technology and intelligent design, bringing new experiences and convenience to family life. By connecting to the internet and using sensor technology, smart appliances can be remotely controlled and intelligently adjusted, making family life more intelligent, comfortable, and convenient.

[0003] Among smart home appliances, smart air conditioners, as intelligent air conditioning devices, offer features such as intelligent control, automatic adjustment, and remote control. Specifically, in terms of defrosting, smart air conditioners utilize advanced sensor technology and intelligent algorithms to achieve precise defrosting. This defrosting function allows users to enjoy a more comfortable and efficient air conditioning experience. In existing technologies, the common defrosting method involves shutting down the unit, switching to cooling mode, performing outdoor defrosting, then shutting down and resuming heating.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present invention described herein can, for example, be implemented in sequences other than those illustrated or described herein.

[0087] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0088] With the continuous development of science and technology, smart home appliances are becoming increasingly popular and an indispensable component of modern families. Smart appliances are more than just simple household appliances; they integrate advanced technology and intelligent design, bringing new experiences and convenience to family life. By connecting to the internet and using sensor technology, smart appliances can be remotely controlled and intelligently adjusted, making family life more intelligent, comfortable, and convenient.

[0089] Among smart home appliances, smart air conditioners, as an intelligent air conditioning device, have functions such as intelligent control, automatic adjustment and remote control. They can effectively adjust the indoor temperature and provide users with a comfortable living and working environment. Especially in terms of defrosting technology, smart air conditioners use advanced sensor technology and intelligent algorithms to achieve precise defrosting of smart air conditioners. Through the defrost function of smart air conditioners, users can enjoy a more comfortable and efficient air conditioning experience.

[0090] When the smart air conditioner runs in heating mode, its outdoor unit is prone to frost. At present, the commonly used defrosting method is: stop - switch to cooling mode for outdoor defrosting - stop - resume heating; outdoor defrosting is performed through intelligent control and switching of cooling mode. When the smart air conditioner enters defrosting, the smart air conditioner stops and switches to cooling mode. The outdoor heat exchanger is in condensing mode, releases heat and defrosts. At this time, the indoor side is in cooling mode. After defrosting, it stops and switches the corresponding operating mode from cooling mode to heating mode, thereby solving the problem of frost on the outdoor unit when the air conditioner runs in heating mode.

[0091] Among them, when the smart air conditioner is performing a defrost operation, in order to achieve the switching of the operating mode, it is necessary to perform a shutdown operation as a transition for the mode switching; however, when the smart air conditioner performs a shutdown operation, the indoor unit stops heating and switches to cooling during defrosting, thereby affecting the user experience of indoor users; at the same time, it may also cause users to mistakenly believe that the air conditioner operating mode is incorrect or the air conditioning system has a fault.

[0092] In response to the above problems, the present application provides a defrost control method for intelligent household appliances.

[0093] First, the implementation scenarios involved in this application are described.

[0094] With the development of science and technology, the services that smart home appliances can provide to users are becoming more and more diverse. Among them, smart air conditioners are one of the indispensable smart devices in people's daily lives. Smart air conditioners can adjust the user's indoor temperature, keep the air clean, adjust the humidity, provide heating functions, and achieve comfortable and convenient environmental management through energy-saving control and remote operation.

[0095] The defrosting method commonly used in existing smart air conditioners for heating requires a mode switch that includes a shutdown operation to achieve the effect of defrosting the outdoor unit. The smart air conditioner involved in this application can be, for example, a smart air conditioner equipped with a newly added refrigerant diversion device, and the device also includes a defrost control valve. By adjusting the opening and closing frequency of the defrost control valve, it is possible to achieve normal heating and simultaneous defrosting of the outdoor side without stopping the machine or changing direction.

[0096] Figure 1 This is a scene diagram of the smart home appliance defrosting control method provided by this application, such as Figure 1As shown, the compressor 101 produces a high-temperature refrigerant medium, which flows into the indoor heat exchanger 104 through the four-way valve 102 and the stop valve 103; the refrigerant medium provides a warm indoor environment for the user through the indoor heat exchanger 104, and after the heat exchange treatment, the refrigerant medium flows from the indoor heat exchanger 104 through the medium valve 105 and the throttling device 106 into the outdoor heat exchanger 108, thereby realizing a complete heat exchange process; among them, the defrost control valve 107 and the refrigerant branch where the defrost control valve 107 is located are the newly added refrigerant diversion devices; the refrigerant medium flowing out of the compressor 101 flows into the refrigerant branch where the defrost control valve 107 is located after passing through the four-way valve 102, and the intelligent air conditioner controls the opening and closing frequency of the defrost control valve 107, and then controls the frequency of the refrigerant medium in the refrigerant branch flowing into the outdoor heat exchanger 108, thereby achieving normal heating while defrosting the outdoor side.

[0097] The present application provides a defrost control method for smart home appliances. The method controls the defrost process of the smart home appliance by adding a defrost control valve and a diverter device to the outdoor unit of the smart home appliance. At the same time, the method obtains the operating frequency, operating power and outdoor temperature of the smart home appliance after the smart home appliance has been running in heating mode for a preset period of time and uses them as the initial parameters of the smart home appliance. The method re-obtains the current operating frequency, operating power and outdoor temperature of the smart home appliance and uses them as the current parameters of the smart home appliance. The method compares the current parameters with the initial parameters to obtain the change of the operating parameters of the smart home appliance and determines the control frequency of the defrost control valve. The method adjusts the opening and closing operation of the defrost control valve according to the control frequency, thereby realizing the defrost processing of the outdoor unit of the smart home appliance. The method realizes the defrost operation of the smart home appliance without shutdown and mode conversion, improves the defrost efficiency of the smart home appliance, ensures the indoor heating effect of the smart home appliance, avoids the defect that the user mistakenly believes that the air conditioner operation mode is wrong or the air conditioner system is disordered when the smart home appliance is defrosted, and the non-stop heating of the smart home appliance improves the user experience.

[0098] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0099] Figure 2 Schematic diagram of the process of the smart home appliance defrosting control method provided in the embodiment of the present application Figure 1 The execution subject of this embodiment can be, for example, a control system of a variable frequency air conditioner equipped with a defrost control valve. Figure 2 As shown, the smart home appliance defrost control method provided in this embodiment includes:

[0100] S201: Obtaining initialization frost parameters and current ambient temperature of the smart home appliance.

[0101] Among them, the defrost parameter is used to indicate the parameter information that can control the smart appliance to perform defrost processing, the initialization frost parameter is used to indicate the parameter information obtained after the operating state of the smart appliance is stable, and the current ambient temperature is used to indicate the temperature value outside the space where the smart appliance is located.

[0102] It is understandable that a plurality of sensors are provided in the smart home appliance. Based on the multiple sensors that have been provided, various defrost parameters at different positions of the smart home appliance can be detected. In addition, the control system can also detect the operating status of the smart home appliance in real time and obtain corresponding operating data. The smart home appliance selects different operating modes according to the needs of the user, and when the smart home appliance starts to run the corresponding operating mode, the smart home appliance is not able to run with high performance from the beginning, but needs to transition gradually and adjust and optimize according to the actual needs of the user and environmental conditions. That is to say, when the smart home appliance can stably provide continuous services according to the needs of the user, the operating status of the smart home appliance tends to be stable.

[0103] The control system detects the operating status of the smart home appliance in real time through multiple sensors set up in the smart home appliance itself, and the control system can also obtain multiple operating data of the smart home appliance; based on the detection values ​​of multiple sensors and the detection values ​​of the operating data, the current operating status of the smart home appliance is determined; when the operating status of the smart home appliance tends to be stable, the multiple data detection values ​​obtained by the smart home appliance at that moment are filtered, and the filtering conditions are parameter information that can control the smart home appliance to perform defrosting processing, thereby obtaining the initialization frost parameters of the smart home appliance; through the sensor for detecting the outdoor ambient temperature set up by the smart home appliance itself, the outdoor ambient temperature of the space where the smart home appliance is currently located can be obtained in real time, and the outdoor ambient temperature is determined as the current ambient temperature.

[0104] For example, the currently acquired defrost parameters include: the operating frequency of the smart air conditioner, the operating power of the smart air conditioner, and the outdoor temperature. This application does not impose any special restrictions on the types of defrost parameters.

[0105] Preferably, obtaining the initialization frost parameters of the smart home appliance includes:

[0106] Obtain the operating mode of the smart home appliance; detect and process the time the smart home appliance runs in the heating mode, and determine the detection result as the detection time; determine whether the detection time is consistent with a second preset time; if the detection time is consistent with the second preset time, obtain the defrost parameters after the smart home appliance runs for the detection time, and determine the defrost parameters as the initialization frost parameters.

[0107] Among them, the operating mode includes: heating mode; the detection time is used to indicate the length of time the smart home appliance continues to run, and the second preset time is used to indicate the lower limit of the time when the operating state of the smart home appliance tends to be stable.

[0108] It can be understood that when smart home appliances provide corresponding services based on user needs, the service intensity that can be provided changes gradually and gradually becomes consistent with user needs as time goes by; the purpose of this step of judging whether the detection time is consistent with the second preset time is to determine whether the operating status of the smart home appliance is stable.

[0109] Obtain the operating mode of the smart home appliance and determine the type of service the user currently needs from the smart home appliance; when the smart home appliance is operating in heating mode, the smart home appliance can provide the user with corresponding heating services, and detect and process the length of time the smart home appliance operates in heating mode, and determine the detection result as the detection duration; determine whether the detection duration is consistent with a second preset duration.

[0110] If the detection time is consistent with the second preset time, it indicates that the current operating status of the smart home appliance tends to be stable, and the service intensity that the smart home appliance can currently provide can meet the service intensity corresponding to the user's needs. At this time, the defrost parameters after the smart home appliance runs for the detection time are obtained, and the defrost parameters are determined as the initialization frost parameters.

[0111] If the detection time is inconsistent with the second preset time, it indicates that the current operating status of the smart home appliance has not stabilized, and the detection time is less than the second preset time. The service intensity that the smart home appliance can currently provide is lower than the service intensity corresponding to the user's needs. At this time, the detection time of the smart home appliance is re-detected, and the judgment of whether the detection time is consistent with the second preset time is continued.

[0112] It can be understood that the detection time of the smart home appliance is obtained in real time. When determining whether the detection time is consistent with the second preset time, the detection time is greater than the second preset time. This is a comparison conclusion that can be obtained on the basis of determining that the detection time is equal to the second preset time. Therefore, only two situations need to be considered: the detection time is less than the second preset time and the detection time is equal to the second preset time.

[0113] For example, the second preset time length can be 6min-20min, and the second preset time length can be selected as 10min currently; when the smart home appliance starts to run in heating mode, the running time of the smart home appliance is detected, and the time length obtained by the detection is determined as the detection time length; if the detection time length is 10min, 10min=10min, then it indicates that the current running state of the smart home appliance tends to be stable. At this time, the defrost parameters after the smart home appliance runs for the detection time length are obtained, and the defrost parameters are determined as the initialization frost parameters; if the detection time length is 5min, 5min<10min, then it indicates that the current running state of the smart home appliance does not tend to be stable. At this time, the detection time length of the smart home appliance is obtained again, and the detection time length is compared with 10min again.

[0114] S202: Determine whether the current ambient temperature is greater than a first preset ambient temperature.

[0115] Among them, the first preset ambient temperature is used to indicate the lower limit value for determining whether frost occurs on the outdoor unit of the smart home appliance. The value range of the lower limit value can be, for example, 3°C-5°C; the target defrost frequency refers to the frequency of opening and closing the defrost control valve of the smart home appliance.

[0116] It can be understood that the smart home appliances involved in this application include: indoor units and outdoor units. The space where the indoor units are located is the space where the smart home appliances are located, and the space where the outdoor units are located is the environmental space outside the space where the smart home appliances are located.

[0117] The purpose of judging whether the current ambient temperature is greater than the first preset ambient temperature in this step is to determine whether frost occurs on the outdoor unit of the smart home appliance.

[0118] If the current ambient temperature is not greater than the first preset ambient temperature, it indicates that the temperature of the current environment in which the outdoor unit of the smart home appliance is located is low, and frost occurs on the outdoor unit. At this time, the current defrost parameters of the smart home appliance are obtained, and the current defrost parameters and the initialization frost parameters are compared to determine the changes in the defrost parameters of the smart home appliance compared to the moment when the operating state tends to be stable. Based on the changes in the defrost parameters before and after, the target defrost frequency of the smart home appliance is determined.

[0119] If the current ambient temperature is greater than the first preset ambient temperature, it indicates that there is no frost on the outdoor unit of the smart home appliance. At this time, based on the current ambient temperature, the length of time the smart home appliance continues to run and the target defrost frequency of the defrost control valve after the smart home appliance runs for this length of time are determined.

[0120] For example, the first preset ambient temperature can be 4°C. If the current ambient temperature is 1°C, and 1°C is less than 4°C, it indicates that the temperature of the ambient space where the outdoor unit of the current smart air conditioner is located is low, and frosting occurs on the outdoor unit of the smart air conditioner. At this time, multiple data detection values ​​of the smart air conditioner at the current moment are obtained, and parameter information that can control the smart home appliance to perform defrosting is screened out, and the parameter information is determined as the current defrost parameter. The current defrost parameter and the initialization frost parameter are compared to determine the change of the smart air conditioner, and then the target defrost frequency of the smart air conditioner is determined. If The current ambient temperature is 6°C, and 6°C>4°C, which indicates that when the smart air conditioner just starts to operate, no frost occurs on the outdoor unit of the smart air conditioner. At this time, according to the current ambient temperature, the length of time the smart air conditioner can continue to operate and the frequency of opening and closing of the defrost control valve are further determined; wherein, the duration corresponding to the defrost frequency can be 1min-5min, and the target defrost frequency can be "open 5 off 10" for 1min: the defrost control valve is open for 5 seconds and closed for 10min, and "open 5 off 5": the defrost control valve is open for 5 seconds and closed for 5 seconds for 3min.

[0121] S203: If the current ambient temperature is not greater than the first preset ambient temperature, obtaining current defrost parameters of the smart home appliance, and determining a target defrost frequency of the smart home appliance according to the current defrost parameters and the initialization defrost parameters.

[0122] S204: adjusting the opening and closing states of the defrost control valve according to the target defrost frequency to perform defrost processing on the smart home appliance.

[0123] The open and close status is used to indicate the open and closed status of the defrost control valve.

[0124] According to the currently acquired target defrost frequency, the frequency of opening and closing of the defrost control valve is controlled, that is, the time when the defrost control valve is in the open state and the closed state is adjusted; when the defrost control valve is in the open state, the high-temperature refrigerant produced by the compressor is introduced into the outdoor unit of the smart home appliance through the refrigerant diversion device newly added to the smart home appliance, so as to realize the defrosting of the outdoor unit of the smart home appliance; when the defrost control valve is in the closed state, the refrigerant circuit corresponding to the newly added refrigerant diversion device is cut off, and the refrigerant diversion device cannot input high-temperature refrigerant to the outdoor unit of the smart home appliance.

[0125] It can be understood that by controlling the frequency of opening and closing of the defrost control valve, the high-temperature refrigerant generated by the smart home appliance is introduced into the outdoor unit, so as to realize indoor heating and outdoor defrosting at the same time; if the defrost control valve is in the open state for too long, most of the high-temperature refrigerant produced by the compressor is introduced into the outdoor unit, which is likely to affect the heating effect of the indoor unit of the smart home appliance; if the defrost control valve is in the closed state for too short a time, that is, too little high-temperature refrigerant is introduced into the outdoor unit of the smart home appliance, it is not conducive to the defrosting of the outdoor unit of the smart home appliance, and the defrosting effect is not obvious; therefore, while ensuring the defrosting effect of the outdoor unit, in order not to affect the heating effect of the indoor unit of the smart home appliance, the defrosting frequency of the defrost control valve is also subject to a time limit; for example, the defrost frequency can be set to seconds, and opened and closed at a high frequency, and the present application does not impose any special restrictions on the specific value of the defrost frequency.

[0126] Preferably, after the smart home appliance completes operation according to the target defrost frequency, the defrost parameters of the smart home appliance are re-detected with the current moment as the starting moment, and the defrost parameters at the corresponding moment after the smart home appliance has run for the second preset time are determined as the initialization frost parameters, and it is re-determined whether the smart home appliance should perform defrost processing, thereby improving the defrost efficiency of the smart home appliance.

[0127] The defrost control method for smart home appliances provided in this embodiment obtains the initialization frost parameters and current ambient temperature of the smart home appliance and determines whether the current ambient temperature is greater than a first preset ambient temperature. If the current ambient temperature is not greater than the first preset ambient temperature, the current defrost parameters of the smart home appliance are obtained. Based on the current defrost parameters and the initialization frost parameters, a target defrost frequency of the smart home appliance is determined. The opening and closing states of the defrost control valve are adjusted according to the target defrost frequency to defrost the smart home appliance. This method implements defrost operation without downtime or mode switching for the smart home appliance, improves the defrost efficiency of the smart home appliance, ensures the indoor heating effect of the smart home appliance, and enhances the user experience by not stopping the heating of the smart home appliance.

[0128] Figure 3 Schematic diagram of the process of the smart home appliance defrosting control method provided in the embodiment of the present application Figure 2 .like Figure 3 As shown, this embodiment Figure 2 Based on the embodiment, the defrost control method of the smart home appliance is described in detail. The defrost control method of the smart home appliance shown in this embodiment includes:

[0129] S301: Obtaining initialization frost parameters and current ambient temperature of the smart home appliance.

[0130] Step S301 is similar to the above-mentioned step S201 and will not be described again here.

[0131] S302: Determine whether the current ambient temperature is greater than a first preset ambient temperature; if so, execute step S303; if not, execute step S306.

[0132] The purpose of this step of judging whether the current ambient temperature is greater than the first preset ambient temperature is to determine whether frost occurs on the outdoor unit of the smart home appliance.

[0133] If the current ambient temperature is greater than the first preset ambient temperature, it indicates that there is no frost on the outdoor unit of the smart home appliance. At this time, the second preset ambient temperature of the smart home appliance is obtained. Based on the second preset ambient temperature and the current ambient temperature, the length of time the smart home appliance continues to run and the target defrost frequency of the defrost control valve after the smart home appliance runs for this length of time are determined.

[0134] If the current ambient temperature is not greater than the first preset ambient temperature, it indicates that frost has occurred on the outdoor unit of the smart home appliance. At this time, the current defrost parameters of the smart home appliance are obtained, and the current defrost parameters and the initialization frost parameters are compared to determine the changes in the defrost parameters of the smart home appliance compared to the moment when the operating state tends to be stable. Based on the changes in the defrost parameters before and after, the target defrost frequency of the smart home appliance is determined.

[0135] S303: Obtain a second preset ambient temperature of the smart home appliance.

[0136] S304: Determine the target duration and the target defrosting frequency of the smart home appliance according to the current ambient temperature and the second preset ambient temperature.

[0137] The second preset ambient temperature may be, for example, 6° C. to 8° C., and the target duration is used to indicate the length of time the smart home appliance continues to operate in the current operating mode.

[0138] Based on the current ambient temperature and the second preset ambient temperature, the temperature condition of the current ambient space of the outdoor unit of the smart home appliance is determined; after determining the current ambient condition of the outdoor unit of the smart home appliance, the length of time that frost will occur in the smart home appliance is predicted, that is, the length of time that the smart home appliance can continue to operate and does not need to be defrosted is predicted, and this time length is determined as the target duration of the smart home appliance; then, based on the current ambient temperature and the second preset ambient temperature of the smart home appliance, the target defrost frequency of the smart home appliance is determined.

[0139] Preferably, the duration includes: a first duration and a second duration, and determining the duration of continuous operation and the target defrosting frequency of the smart home appliance according to the current ambient temperature and the second preset ambient temperature includes:

[0140] Determine whether the current ambient temperature is greater than the second preset ambient temperature; if the current ambient temperature is greater than the second preset ambient temperature, determine the first duration as the target duration, and determine the second defrost frequency as the target defrost frequency; if the current ambient temperature is not greater than the second preset ambient temperature, determine the second duration as the target duration, and determine the second defrost frequency as the target defrost frequency.

[0141] Among them, the second defrost frequency can be, for example, "on 5 off 5": the defrost control valve is open for 5 seconds and closed for 5 seconds and runs for 3 minutes; the duration is used to indicate the length of time the smart home appliance continues to run in the current operating mode, and the first duration is greater than the second duration.

[0142] It can be understood that when the current ambient temperature is greater than the first preset ambient temperature, the outdoor unit of the smart home appliance is at this ambient temperature, and the external ambient temperature has little effect on the frosting of the outdoor unit, and at this time the outdoor unit is not prone to frost. In other words, if the smart home appliance frosts, the reason for the frosting is that after the smart home appliance starts heating, the temperature of the refrigerant flowing into the outdoor unit is low, causing the outdoor unit to frost. Therefore, under the condition that the current ambient temperature is greater than the first preset ambient temperature, the smart home appliance can be defrosted at the same defrost frequency.

[0143] The purpose of this step of judging whether the current ambient temperature is greater than the second preset ambient temperature is to determine the length of time the smart home appliance continues to operate in the current operating mode.

[0144] The relationship between the current ambient temperature and the second preset ambient temperature affects the length of time the smart home appliance runs after obtaining the initial frost parameters until frosting occurs; if the current ambient temperature is greater than the second preset ambient temperature, it indicates that the ambient temperature of the outdoor unit of the smart home appliance is higher than the ambient temperature where frosting is prone to occur, and the smart home appliance will not frost in the initial stage of operation. As the running time increases, the probability of frosting also increases. At this time, the first duration is determined as the target duration, and the second defrost frequency is determined as the target defrost frequency.

[0145] If the current ambient temperature is not greater than the second preset ambient temperature, it indicates that the ambient temperature of the outdoor unit of the smart home appliance is higher than the ambient temperature where frost is likely to occur, but the probability of frost occurring is lower than when the current ambient temperature is greater than the second preset ambient temperature. At this time, the second duration is determined as the target duration, and the second defrost frequency is determined as the target defrost frequency.

[0146] Preferably, historical defrost data is obtained, and the length of time between the moment when the operating state of the smart home appliance tends to be stable and the moment when frosting begins to appear under different ambient temperatures and operating modes is determined based on the historical defrost data, and this time length is used as the duration under the corresponding ambient temperature and operating mode; when the smart home appliance determines the current ambient temperature and the second preset ambient temperature, the duration corresponding to the current smart home appliance is determined based on the current operating mode of the smart home appliance and the corresponding temperature judgment result.

[0147] For example, the first duration can be: 40min-500min, and the second duration can be: 90min-150min; during the current temperature judgment process, the first duration can be selected as 400min, the second duration can be selected as 120min, and the second preset ambient temperature can be 7°C; if the current ambient temperature is 10°C, 10°C>7°C, it indicates that the ambient temperature of the outdoor unit of the smart air conditioner is higher than the ambient temperature where frosting is prone to occur, and the smart home appliance will not experience frosting in the initial operation. At this time, 400min is determined as the target duration, and "on 5 off 5" is determined as the target defrost frequency; if the current ambient temperature is 6°C, 6°C<7°C, it indicates that the ambient temperature of the outdoor unit of the smart air conditioner is higher than the ambient temperature where frosting is prone to occur, but the probability of frosting is higher than when the current ambient temperature is 10°C. At this time, 120min is determined as the target duration, and "on 5 off 5" running for 3 minutes is determined as the target defrost frequency. This application does not impose any special restrictions on the determination of duration.

[0148] S305: Control the smart home appliance to continue running according to the target duration.

[0149] It can be understood that the operation mode of the smart home appliance includes a heating mode, and the defrosting operation of the outdoor unit is mainly performed when the smart home appliance is operating in the heating mode.

[0150] After determining the target duration for the smart home appliance to continue operating, the smart home appliance is controlled to maintain the current operating mode and corresponding operating parameters for the target duration, and the continuous operation process must ensure that the heating effect of the smart home appliance can meet the user's heating needs.

[0151] S306: Obtain current defrost parameters of the smart home appliance.

[0152] S307: Obtain the operating time and coil temperature of the smart home appliance.

[0153] S308: Performing difference processing on the current outdoor temperature and the coil temperature, and determining the result of the difference processing as a first temperature difference.

[0154] S309: Determine a frequency measurement condition of the smart home appliance according to the first temperature difference and the operating time.

[0155] Among them, the running time is used to indicate the length of time the smart home appliance continues to run after obtaining the initialization frost parameters; the coil temperature is used to indicate the temperature of the outdoor unit coil of the smart home appliance; the frequency measurement condition is used to indicate whether the smart home appliance starts to measure the target defrost frequency, and the first temperature difference is used to indicate the lower limit of the current outdoor temperature and the coil temperature.

[0156] It can be understood that the current outdoor temperature and the current ambient temperature are essentially the same, both being the temperature of the current environment in which the outdoor unit of the smart home appliance is located. Different expressions are used when making different temperature judgments.

[0157] The operating time and coil temperature of the smart home appliance are obtained, and the difference between the current outdoor temperature and the coil temperature is processed, that is, the difference between the current outdoor temperature and the coil temperature is calculated. At this time, the difference is determined as the first temperature difference. The first temperature difference reflects whether the outdoor unit of the current smart home appliance is frosted. Combined with the operating time of the smart home appliance, it is further determined whether the outdoor unit is frosted. While determining that the outdoor unit of the smart home appliance is frosted, the defrost frequency of the defrost control valve can be measured. If the outdoor unit is not frosted, the corresponding determination logic for determining the defrost frequency can be not executed. That is, based on the first temperature difference and the operating time of the smart home appliance, it can be determined whether the control logic for determining the defrost frequency of the smart home appliance is executed, and it is determined whether the control logic for determining the defrost frequency of the smart home appliance executes different states corresponding to the frequency measurement situation.

[0158] Preferably, the frequency measurement status includes: an operating state and a standby state, and determining the frequency measurement status of the smart home appliance according to the first temperature difference and the operating time includes:

[0159] Determine whether the first temperature difference is greater than the first preset temperature difference and whether the running time is greater than the first preset time; if the first temperature difference is greater than the first preset temperature difference and the running time is greater than the first preset time, determine that the frequency measurement of the smart home appliance is in the running state; if the first temperature difference is not greater than the first preset temperature difference and / or the running time is not greater than the first preset time, determine that the frequency measurement of the smart home appliance is in the standby state.

[0160] Among them, the first preset time length can be, for example, 35min-50min, the first preset temperature difference is used to indicate the temperature difference between the outdoor unit coil of the smart home appliance and the environment in which the outdoor unit is located, the running state is used to instruct the smart home appliance to execute the control logic for determining the defrost frequency, and the standby state is used to instruct the smart home appliance not to execute the control logic for determining the defrost frequency.

[0161] The purpose of judging whether the first temperature difference is greater than the first preset temperature difference and whether the operation time is greater than the first preset time in this step is to determine whether to execute the control logic for determining the defrosting frequency.

[0162] If the first temperature difference is greater than the first preset temperature difference and the operating time is greater than the first preset time, it indicates that the temperature difference between the current smart home appliance outdoor unit coil and the external ambient temperature is large, and the main reason for the large temperature difference is the inflow of low-temperature refrigerant, and the outdoor unit has obvious frosting. At this time, it can be determined that the frequency measurement of the smart home appliance is in operation, and the target defrost frequency of the smart home appliance can be determined.

[0163] If the first temperature difference is not greater than the first preset temperature difference and / or the running time is not greater than the first preset time, it indicates that the current smart home appliance outdoor unit coil is basically consistent with the external ambient temperature, and the frost phenomenon of the outdoor unit is not obvious. At this time, it can be determined that the frequency measurement of the smart home appliance is in standby state, and the detection of the running time and the calculation of the first temperature difference are maintained until the frequency measurement state is changed from standby state to running state.

[0164] For example, the first preset duration can be 40 minutes, and the first preset temperature difference can be 1°C-3°C. Here, the first preset temperature difference can be 2°C; if the current outdoor temperature is 2°C, the coil temperature is minus 1°C, and the operating time is 50 minutes, then the corresponding first temperature difference is 3°C. 3°C>2°C and 50min>40min, which indicates that the temperature difference between the outdoor unit coil of the current smart air conditioner and the external ambient temperature is large, and the main reason for the large temperature difference is the inflow of low-temperature refrigerant, which makes the outdoor unit frosting obvious. At this time, the smart home appliance can perform defrost processing, and then the control logic for determining the defrost frequency can be executed, and the smart home appliance can be determined. The frequency measurement status of the smart home appliance is in the running state; if the current outdoor temperature is 2°C, the coil temperature is 1°C, and the running time is 30 minutes, then the corresponding first temperature difference is 1°C, 1°C < 2°C and 30min < 40min, which indicates that the outdoor unit coil of the current smart air conditioner is basically consistent with the external ambient temperature, and the frosting phenomenon of the outdoor unit is not obvious. At this time, the smart home appliance does not need to be defrosted, and it is determined that the frequency measurement status of the smart home appliance is in the standby state; in addition, after determining that the frequency measurement status is in the standby state, the detection of the running time and the calculation of the first temperature difference are maintained until the frequency measurement status is changed from the standby state to the running state.

[0165] S310: When the frequency measurement condition is in the running state, determine whether the current operating frequency is equal to the initial operating frequency; if so, execute step S311; if not, execute step S314.

[0166] Among them, the first defrost frequency can be, for example, "open 5, close 10": the defrost control valve is open for 5 seconds and closed for 10 seconds and runs for 1 minute. The decay rate is used to indicate the change in the operating power at the current moment compared to the operating power at the initial moment.

[0167] It can be understood that the current operating frequency corresponds to the current defrost parameter, and the initial operating frequency corresponds to the initialization defrost parameter.

[0168] The purpose of judging whether the current operating frequency is equal to the initial operating frequency in this step is to determine whether the temperature of the ambient space where the outdoor unit of the smart home appliance is located has changed.

[0169] If the current operating frequency is equal to the initial operating frequency, it indicates that the temperature of the ambient space where the outdoor unit of the smart home appliance is located has not changed significantly, and the conditions of the ambient space where the outdoor unit is located corresponding to the current operating frequency and the initial operating frequency are basically the same. At this time, the ratio of the current operating power to the initial operating power is calculated, and the ratio result is determined as the attenuation rate of the operating power of the smart home appliance.

[0170] If the current operating frequency is not equal to the initial operating frequency, it indicates that the temperature of the ambient space where the outdoor unit of the smart home appliance is located has changed, and there is a difference in the conditions of the ambient space where the outdoor unit is located corresponding to the current operating frequency and the initial operating frequency. The change in external ambient temperature affects the operating frequency of the smart home appliance. At this time, the first defrost frequency is determined as the target defrost frequency.

[0171] S311: Determine the attenuation rate of the operating power according to the current operating power and the initial operating power.

[0172] S312: Performing absolute difference processing on the current outdoor temperature and the initial outdoor temperature, and determining a result of the absolute difference processing as a second temperature difference.

[0173] S313: Determine a target defrost frequency of the smart home appliance according to the second temperature difference and the attenuation rate.

[0174] The second temperature difference is used to indicate the temperature difference between the current moment corresponding to the current defrost parameter and the initial moment corresponding to the initial frost parameter.

[0175] Calculate the temperature difference between the current outdoor temperature and the initial outdoor temperature, perform absolute value processing on the temperature difference, and determine the result of the absolute value processing as the second temperature difference; based on the second temperature difference and the attenuation rate, analyze and process the frost condition of the outdoor unit of the smart home appliance at the current moment, and determine the target defrost frequency of the smart home appliance based on the result of the analysis and processing.

[0176] Preferably, determining the target defrost frequency of the smart appliance according to the second temperature difference and the attenuation rate includes:

[0177] Obtain a second preset temperature difference of the smart home appliance; determine whether the second temperature difference is greater than the second preset temperature difference and / or whether the attenuation rate is greater than the preset attenuation rate; if the second temperature difference is greater than the second preset temperature difference and / or the attenuation rate is greater than the preset attenuation rate, determine the first defrost frequency as the target defrost frequency; if the second temperature difference is not greater than the second preset temperature difference and the attenuation rate is not greater than the preset attenuation rate, determine the second defrost frequency as the target defrost frequency.

[0178] The second preset temperature difference may be, for example, 0° C.-2° C., and the preset attenuation rate may be, for example, 0.7-0.9.

[0179] The purpose of judging whether the second temperature difference is greater than the second preset temperature difference and / or whether the attenuation rate is greater than the preset attenuation rate in this step is to determine whether the frosting phenomenon of the outdoor unit of the smart home appliance is serious.

[0180] If the second temperature difference is greater than the second preset temperature difference and / or the attenuation rate is greater than the preset attenuation rate, it indicates that the outdoor temperature at the current moment has changed compared with the outdoor temperature at the initial moment, and / or the operating power of the smart home appliance at the current moment is basically the same as that at the initial moment, and the attenuation is small. At this time, the external ambient temperature has a positive impact on the efficiency of the defrosting treatment of the smart home appliance, and the first defrost frequency can be determined as the target defrost frequency; after controlling the defrost control valve to operate according to the target defrost frequency, the outdoor temperature, coil temperature and operating time of the smart home appliance are re-detected, and it is re-determined whether to execute the control logic for determining the defrost frequency.

[0181] If the second temperature difference is not greater than the second preset temperature difference and the attenuation rate is not greater than the preset attenuation rate, it indicates that the outdoor temperature at the current moment is basically the same as the outdoor temperature at the initial moment, the temperature change is small, and the operating power of the smart home appliance at the current moment is attenuated compared to the operating power at the initial moment. At this time, the second defrost frequency is determined as the target defrost frequency.

[0182] For example, the second preset temperature difference can be 1°C, and the preset attenuation rate can be 0.9. If the currently obtained second temperature difference is 2°C and the attenuation rate is 1, it indicates that the temperature difference between the outdoor temperature of the smart air conditioner at the current moment and the initial moment is large, and the external environment affects the frosting phenomenon of the outdoor unit. The operating power before and after has not changed. At this time, there is frosting on the outdoor unit of the smart air conditioner, but the frost layer at the current moment is relatively thin, so "open 5 close 10" can be used as the target defrost frequency of the defrost control valve; if the currently obtained second temperature difference is 0°C and the attenuation rate is 0.8, it indicates that the outdoor temperature corresponding to the current moment and the initial moment of the smart air conditioner is basically the same, the external environment has no effect on the frosting phenomenon of the outdoor unit, the operating power before and after is attenuated, and the performance of the smart air conditioner is reduced. At this time, there is frosting on the outdoor unit of the smart air conditioner, and the frost layer at the current moment is relatively thick, so "open 5 close 5" can be used as the target defrost frequency of the defrost control valve.

[0183] S314: Determine the first defrost frequency as the target defrost frequency.

[0184] S315: adjusting the opening and closing states of the defrost control valve according to the target defrost frequency to perform defrost processing on the smart home appliance.

[0185] Step S315 is similar to the above-mentioned step S204 and will not be described again here.

[0186] The defrost control method for smart home appliances provided in this embodiment obtains the initialization frost parameters and the current ambient temperature of the smart home appliance, and determines whether the current ambient temperature is greater than a first preset ambient temperature; if the current ambient temperature is not greater than the first preset ambient temperature, obtains a second preset ambient temperature, and determines the target duration and target defrost frequency of the smart home appliance based on the second preset ambient temperature and the current ambient temperature; if the current ambient temperature is not greater than the first preset ambient temperature, obtains the current defrost parameters, operating time and coil temperature of the smart home appliance, performs difference processing on the current outdoor temperature and the coil temperature to obtain a first temperature difference, and determines the target duration and target defrost frequency of the smart home appliance based on the second preset ambient temperature and the current ambient temperature. The first temperature difference and the operating time are used to determine the frequency measurement status of the smart home appliance; when the frequency measurement status is in the operating state, it is determined whether the current operating frequency is equal to the initial operating frequency; if the two are equal, the operating power attenuation rate is determined based on the current operating power and the initial operating power, and the current outdoor temperature and the initial outdoor temperature are processed by absolute difference to obtain the second temperature difference, and the target defrost frequency of the smart home appliance is determined based on the second temperature difference and the attenuation rate; if the two are not equal, the first defrost frequency is determined as the target defrost frequency; the opening and closing state of the defrost control valve is adjusted according to the target defrost frequency to defrost the smart home appliance. This method realizes the defrost operation of the smart home appliance without shutdown and mode conversion, improves the defrost efficiency of the smart home appliance, ensures the indoor heating effect of the smart home appliance, avoids the defect that the user mistakenly believes that the air conditioner operation mode is wrong or the air conditioning system is disordered when the smart home appliance is defrosting, and the non-stop heating of the smart home appliance improves the user experience.
