[0002] Currently, the most important performance feature of frost-free refrigerators is defrosting. Ensuring timely defrosting is a problem that refrigerators must solve. The defrost cycle is related to the operating time of the compressor, the frequency of use by the user, the ambient temperature, and the ambient humidity. Currently, most frost-free refrigerators only take the operating time of the compressor and the frequency of use by the user into account, and do not include ambient temperature and humidity as factors affecting the defrost cycle. It is well known that high-humidity gas at the same temperature and high-temperature gas at the same humidity have relatively high water content. When passing through the evaporator, the amount of water that can be diluted is relatively high. The evaporator frosts quickly, and defrost control needs to be activated in a relatively short time. Therefore, existing frost-free refrigerators do not add ambient temperature and humidity to the factors affecting the defrost cycle, resulting in low defrost efficiency.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] Refrigerators without ambient temperature and humidity sensors cannot obtain ambient temperature and humidity data, resulting in inaccurate defrost judgment and low defrost efficiency.

[0050] Combine Figure 1 As shown, an embodiment of the present disclosure provides a method for defrosting a refrigerator, comprising:

[0051] S101, the refrigerator receives the ambient temperature, ambient humidity, and operating time of the external smart home appliance sent by an external smart home appliance in the same room as the refrigerator.

[0052] S102, the refrigerator determines the equivalent operating time of the refrigerator based on the ambient temperature, ambient humidity, evaporator temperature, operating time of external smart home appliances, equivalent door opening time of the refrigerator, and accumulated actual operating time of the refrigerator.

[0053] S103: The refrigerator determines a time point for triggering a defrost mode according to a relationship between the equivalent operating time and a defrost time threshold.

[0054] According to the method for defrosting a refrigerator provided by the embodiment of the present disclosure, a refrigerator without an ambient temperature and humidity sensor receives the ambient temperature, ambient humidity, and operating time of the external smart home appliance sent by an external smart home appliance in the same room as the refrigerator, and converts the ambient temperature, ambient humidity, operating time of the external smart home appliance, the equivalent door opening time of the refrigerator, and the accumulated actual operating time of the refrigerator into the equivalent operating time of the refrigerator. The equivalent operating time of the refrigerator is conducive to more accurately and visually reflecting the impact of the ambient temperature and humidity and the external smart home appliance on the degree of frost, and then determining the time when the refrigerator triggers the defrost mode by the relationship between the equivalent operating time and the defrost time threshold. In this way, obtaining temperature and humidity data related to defrost and the operating time of the external smart home appliance through the external smart home appliance is conducive to more accurately determining the time when the refrigerator triggers the defrost mode, thereby improving the accuracy of the defrost judgment and further improving the defrost efficiency of the refrigerator.

[0055] Optionally, the defrost time threshold value ranges from [100 hours, 150 hours]. Specifically, the defrost time threshold value can be 100 hours, 110 hours, 120 hours, 130 hours, 140 hours, or 150 hours. It should be noted that the defrost time threshold value can be adjusted based on the actual volume of the refrigerator and the size of the evaporator, and these values ​​are not listed here. This helps to more accurately determine the time when the refrigerator triggers defrost mode.

[0056] Optionally, the refrigerator determines the equivalent operating time of the refrigerator based on the ambient temperature, ambient humidity, evaporator temperature, operating time of external smart home appliances, equivalent door-opening time of the refrigerator, and accumulated actual operating time of the refrigerator, including: the refrigerator determines the equivalent operating time of the refrigerator based on the type of external smart home appliances in the same room as the refrigerator, the ambient temperature, ambient humidity, evaporator temperature, operating time of external smart home appliances, equivalent door-opening time of the refrigerator, and accumulated actual operating time of the refrigerator.

[0057] In this way, a refrigerator without an ambient temperature and humidity sensor can receive ambient temperature, humidity, and operating time of an external smart appliance in the same room as the refrigerator. The sensor then converts the type of external smart appliance, ambient temperature, humidity, operating time of the external smart appliance, the equivalent door-opening time of the refrigerator, and the accumulated actual operating time of the refrigerator into the refrigerator's equivalent operating time. The refrigerator's equivalent operating time helps more accurately and visually reflect the impact of ambient temperature and humidity and external smart appliances on the degree of frost. This helps more accurately determine the moment when the refrigerator triggers defrost mode, thereby improving the accuracy of defrost judgment and, in turn, the refrigerator's defrost efficiency.

[0058] Optionally, the refrigerator determines the equivalent operating time of the refrigerator based on the type of the external smart home appliance in the same room with the refrigerator, the ambient temperature, the ambient humidity, the evaporator temperature, the operating time of the external smart home appliance, the equivalent door opening time of the refrigerator, and the accumulated actual operating time of the refrigerator, including: the refrigerator determines the equivalent operating time of the refrigerator based on the type of the external smart home appliance in the same room with the refrigerator, Tk tempi and the operating time of the i-th external smart home appliance to determine Tk i . Refrigerator according to Tw i Tr i 、Tz i 、Tk i , Ty, determine Tmax. Where Tmax is the equivalent operating time. Tk tempi Tk is the actual door opening time when the refrigerator is opened for the i-th time. i = is the equivalent opening time of the refrigerator door when it is opened for the i-th time. The running time of the i-th external smart home appliance is the running time of the external smart home appliance when the refrigerator door is opened for the i-th time. i Tr is the ambient temperature sent by the external smart home appliance when the refrigerator door is opened for the i-th time. i Tz is the ambient humidity sent by the external smart home appliance when the refrigerator door is opened for the i-th time; i is the evaporator temperature when the refrigerator door is opened for the i-th time. i = 1, 2, ..., n, where n is the total number of times the refrigerator door is opened.

[0059] In this way, the equivalent door-opening time of the refrigerator is first calculated based on the type of external smart home appliance in the same room as the refrigerator, the actual door-opening time each time the refrigerator door is opened, and the corresponding external smart home appliance operating time. The equivalent door-opening time of the refrigerator helps to more accurately and visually reflect the impact of ambient temperature and humidity and external smart home appliances on the degree of frost. The equivalent operating time of the refrigerator is then converted based on the ambient temperature, humidity, equivalent door-opening time received by the refrigerator each time, the refrigerator's own evaporator temperature, and the accumulated actual operating time of the refrigerator. The equivalent operating time of the refrigerator helps to more accurately and visually reflect the impact of ambient temperature and humidity and external smart home appliances on the degree of frost. This helps to more accurately determine the time when the refrigerator triggers defrost mode, thereby improving the accuracy of defrost judgment and, in turn, the refrigerator's defrost efficiency.

[0060] Optionally, the operating time of the i-th external smart home appliance includes: the operating time of the i-th gas stove and / or the operating time of the i-th air conditioner and / or the operating time of the i-th humidifier. tempi and the operating time of the i-th external smart home appliance to determine the i-th equivalent door opening time Tk of the refrigerator i, including: When the type of external smart home appliance device in the same room as the refrigerator is a gas stove, according to Tk tempi and the running time of the i-th gas stove, determine Tk i Or, when the type of external smart home appliance in the same room as the refrigerator is an air conditioner, the refrigerator can tempi and the running time of the i-th air conditioner, determine Tk i Or, when the external smart home appliance in the same room as the refrigerator is a humidifier, according to Tk tempi and the running time of the i-th humidifier, determine Tk i .

[0061] In this way, if the external smart home appliance in the same room as the refrigerator is a gas stove, the actual door opening time each time the refrigerator door is opened and the corresponding gas stove operating time are converted into the corresponding refrigerator door opening time. The refrigerator's equivalent door opening time helps more accurately and visually reflect the impact of ambient temperature and humidity and the gas stove on the degree of frost formation. If the external smart home appliance in the same room as the refrigerator is an air conditioner, the air conditioner's operating mode, the actual door opening time each time the refrigerator door is opened, and the corresponding air conditioner operating time are converted into the corresponding refrigerator door opening time. The refrigerator's equivalent door opening time helps more accurately and visually reflect the impact of ambient temperature and humidity and the air conditioner on the degree of frost formation. If the external smart home appliance in the same room as the refrigerator is a humidifier, the actual door opening time each time the refrigerator door is opened and the corresponding humidifier operating time are converted into the corresponding refrigerator door opening time. The refrigerator's equivalent door opening time helps more accurately and visually reflect the impact of ambient temperature and humidity and the humidifier on the degree of frost formation. This helps to more accurately determine the moment when the refrigerator triggers the defrost mode, thereby improving the accuracy of defrost judgment and further improving the defrost efficiency of the refrigerator.

[0062] Optionally, the refrigerator is based on Tk tempi and the running time of the i-th gas stove, determine Tk i , including: Refrigerator Calculation Tk i =x 1i ×Tk tempi Among them, x 1i is the equivalent coefficient of the i-th gas stove, which is positively correlated with the operating time of the i-th gas stove. 1i The value range of is [1, +∞).

[0063] Opening the refrigerator door causes moisture in the air to form frost on the evaporator. Since cooking is often done while the gas stove is operating, the moisture content in the air increases, which accelerates the rate at which moisture in the air forms frost on the evaporator when the refrigerator door is opened. Furthermore, the longer the gas stove is running, the faster the frost forms. This translates to a longer equivalent door-opening time for the refrigerator, resulting in a longer equivalent operating time. This helps more accurately and visually reflect the impact of ambient temperature, humidity, and the gas stove on frost formation. As the frost formation rate increases, the time it takes for the equivalent operating time to reach the defrost time becomes shorter, accelerating the defrost triggering process. This helps more accurately determine when the refrigerator triggers defrost mode, thereby improving the accuracy of defrost determination and, consequently, the refrigerator's defrost efficiency.

[0064] Optionally, the refrigerator can be operated according to the operating mode of the air conditioner, Tk tempi and the running time of the i-th air conditioner, determine Tk i , including: when the refrigerator is in cooling mode, calculate Tk i =x 2i ×Tk tempi ; where x 2i is the cooling equivalent coefficient of the i-th air conditioner, which is negatively correlated with the operating time of the i-th air conditioner. Or, when the refrigerator is in the heating mode, calculate Tk i =x 3i ×Tk tempi Among them, x 3i is the heating equivalent coefficient of the i-th air conditioner, which is positively correlated with the operating time of the i-th air conditioner. 2i The value range is (-∞, 1], x 3i The value range of is [1, +∞).

[0065] In this way, opening the refrigerator door will cause moisture in the air to form frost on the evaporator. Since the water content in the air often increases when the air conditioner is running in heating mode, the speed at which moisture in the air forms frost on the evaporator will increase when the refrigerator door is opened. The longer the air conditioner runs in heating mode, the faster the frost will form. The equivalent door opening time of the corresponding refrigerator will be longer, which will cause the equivalent operating time to become longer. This is conducive to more accurately and visually reflecting the impact of ambient temperature and humidity and gas stoves on the degree of frost. In order to increase the frost speed, the time when the equivalent operating time reaches the defrost time will become shorter, thereby accelerating the triggering of defrost. However, since the air conditioner's cooling mode often reduces the amount of water in the air, the rate at which moisture in the air forms frost on the evaporator when the refrigerator door is opened slows down. Furthermore, the longer the air conditioner is in cooling mode, the slower the frost formation rate. This translates to a shorter equivalent door-opening time for the refrigerator, resulting in a shorter equivalent operating time. This helps more accurately and visually reflect the impact of ambient temperature, humidity, and the gas stove on frost formation. To slow down the frost formation rate, the time it takes for the equivalent operating time to reach the defrost time becomes longer, delaying the defrost triggering. This helps more accurately determine when the refrigerator triggers defrost mode, thereby improving the accuracy of defrost determination and, consequently, the refrigerator's defrost efficiency.

[0066] Optionally, the refrigerator is based on Tk tempi and the running time of the i-th humidifier, determine Tk i , including: Refrigerator Calculation Tk i =x 4i ×Tk tempi Among them, x 4i is the equivalent coefficient of the i-th humidifier, which is positively correlated with the operating time of the i-th humidifier. Specifically, x 4i The value range of is [1, +∞).

[0067] Opening the refrigerator door will cause moisture in the air to form frost on the evaporator. Since the humidifier often increases the moisture content in the air when it is operating, the frost forms on the evaporator faster when the refrigerator door is opened. Furthermore, the longer the humidifier runs, the faster the frost forms. This translates to a longer equivalent door-opening time for the refrigerator, resulting in a longer equivalent operating time. This helps more accurately and visually reflect the impact of ambient temperature, humidity, and the gas stove on frost formation. As the frost formation speed increases, the time it takes for the equivalent operating time to reach the defrost time becomes shorter, accelerating the defrost triggering process. This helps more accurately determine when the refrigerator triggers defrost mode, thereby improving the accuracy of defrost determination and, in turn, the refrigerator's defrost efficiency.

[0068] Optionally, the refrigerator is based on Tw i Tr i 、Tz i 、Tki , Ty, determine Tmax, including: refrigerator calculation Tmax = Ty + (Tw1-Tz1) × Tr1 × Tk1 + (Tw2-Tz2) × Q × Tr2 × Tk2 + (Tw3-Tz3) × Q × Tr3 × Tk3 + ... + (Tw n -Tz n )×Tr n ×Tk n Where Q is a fixed coefficient. Specifically, the value of Q can be 0.2.

[0069] This allows for more accurate calculation of the refrigerator's equivalent operating time based on the ambient temperature, humidity, equivalent door-opening time, the refrigerator's own evaporator temperature, and the refrigerator's accumulated actual operating time. This equivalent operating time more accurately and visually reflects the impact of ambient temperature and humidity, as well as external smart appliances, on frost formation. This helps more accurately determine when the refrigerator triggers defrost mode, thereby improving the accuracy of defrost judgment and, consequently, the refrigerator's defrost efficiency.

[0070] Optionally, the refrigerator determines the equivalent operating time of the refrigerator based on the type of external smart home appliance in the same room as the refrigerator, the ambient temperature, the ambient humidity, the evaporator temperature, the operating time of the external smart home appliance, the equivalent door-opening time of the refrigerator, and the accumulated actual operating time of the refrigerator, including: if there are multiple types of external smart home appliances in the same room as the refrigerator, the refrigerator determines a comprehensive equivalent coefficient based on the equivalent coefficient corresponding to each external smart home appliance. The refrigerator determines the equivalent operating time of the refrigerator corresponding to the type of external smart home appliance in the same room as the refrigerator based on the comprehensive equivalent coefficient, the ambient temperature, the ambient humidity, the evaporator temperature, the operating time of the external smart home appliance, the equivalent door-opening time of the refrigerator, and the accumulated actual operating time of the refrigerator.

[0071] In this way, if there are multiple types of external smart home appliances in the same room as the refrigerator, a comprehensive equivalent coefficient is determined based on the equivalent coefficient corresponding to each external smart home appliance. Then, based on the comprehensive equivalent coefficient, ambient temperature, ambient humidity, evaporator temperature, external smart home appliance operating time, refrigerator door equivalent open time, and the accumulated actual operating time of the refrigerator, the equivalent operating time of the refrigerator corresponding to the type of external smart home appliance in the same room is more accurately converted. This helps to more accurately determine the time when the refrigerator triggers defrost mode, thereby improving the accuracy of defrost judgment and the defrost efficiency of the refrigerator.

[0072] Optionally, the refrigerator determines a comprehensive equivalent coefficient according to the equivalent coefficient corresponding to each external smart home appliance, including: the refrigerator calculates x=1+(x1-1)+(x2-1)+…+(x m-1). Among them, x is the comprehensive equivalent coefficient, x j is the equivalent coefficient corresponding to the jth external smart home appliance. j = 1, ..., m; m is the number of external smart home appliances in the same room as the refrigerator. Specifically, the value range of x is [0.5, 1.5].

[0073] In this way, if the external smart home appliances in the same room as the refrigerator include multiple types, it is helpful to more accurately determine the comprehensive equivalence coefficient based on the equivalence coefficient corresponding to each external smart home appliance.

[0074] Optionally, the refrigerator determines the equivalent operating time of the refrigerator corresponding to the type of the external smart home appliance in the same room as the refrigerator based on the comprehensive equivalent coefficient, the ambient temperature, the ambient humidity, the evaporator temperature, the operating time of the external smart home appliance, the equivalent door opening time of the refrigerator, and the accumulated actual operating time of the refrigerator, including: the refrigerator determines the equivalent door opening time of the refrigerator based on the actual door opening time of the refrigerator and the operating time of the external smart home appliance. The refrigerator determines the equivalent operating time of the refrigerator corresponding to the type of the external smart home appliance in the same room as the refrigerator based on the ambient temperature, the ambient humidity, the evaporator temperature, the equivalent door opening time of the refrigerator, and the accumulated actual operating time of the refrigerator.

[0075] Specifically, the refrigerator determines the equivalent door opening time of the refrigerator based on the actual door opening time of the refrigerator and the operating time of the external smart home appliance, including: the refrigerator determines the equivalent door opening time of the refrigerator as the product of the actual door opening time of the refrigerator and the operating time of the external smart home appliance.

[0076] In this way, if there are multiple types of external smart appliances in the same room as the refrigerator, the actual door opening time of each refrigerator and the corresponding external smart appliance operating time are first converted into the equivalent door opening time of each refrigerator. Then, the ambient temperature, ambient humidity, evaporator temperature, equivalent door opening time of the refrigerator, and the accumulated actual operating time of the refrigerator are converted into the equivalent operating time of the refrigerator corresponding to the type of external smart appliance in the same room. This helps to more accurately determine the time when the refrigerator triggers defrost mode, thereby improving the accuracy of defrost judgment and the defrost efficiency of the refrigerator.

[0077] Optionally, before the refrigerator determines the time to trigger the defrost mode based on the relationship between the equivalent operating time and the defrost time threshold, the refrigerator further includes: receiving the ambient temperature and humidity sent by a third-party platform when no external smart home appliance is located in the same room as the refrigerator. The refrigerator determines the equivalent operating time of the refrigerator based on the ambient temperature, humidity, evaporator temperature, the equivalent door opening time of the refrigerator, and the accumulated actual operating time of the refrigerator.

[0078] In this way, if there are no external smart home appliances in the same room as the refrigerator, the refrigerator's equivalent operating time is determined based on the ambient temperature and humidity sent by the third-party platform, the refrigerator's own evaporator temperature, the equivalent door open time, and the accumulated actual operating time. This helps to more accurately determine the time when the refrigerator triggers defrost mode, taking into account the situation where refrigerators without ambient temperature and humidity sensors are not connected to external smart home appliances, thereby improving the accuracy of defrost judgment and ultimately the refrigerator's defrost efficiency.

[0079] Optionally, the refrigerator determines the equivalent operating time of the refrigerator based on the ambient temperature, ambient humidity, evaporator temperature, equivalent door opening time of the refrigerator, and accumulated actual operating time of the refrigerator, including: the refrigerator determines the equivalent ambient temperature based on the ambient temperature. The refrigerator determines the equivalent operating time of the refrigerator based on the equivalent ambient temperature, ambient humidity, evaporator temperature, equivalent door opening time of the refrigerator, and accumulated actual operating time of the refrigerator.

[0080] In this way, if there are no external smart home appliances in the same room as the refrigerator, the equivalent ambient temperature is first determined based on the ambient temperature. Then, the equivalent ambient temperature, ambient humidity, evaporator temperature, equivalent door open time, and accumulated actual refrigerator operating time are converted into the refrigerator's equivalent operating time. This helps to more accurately determine the time when the refrigerator triggers defrost mode, taking into account the situation where refrigerators without ambient temperature and humidity sensors are not linked to external smart home appliances, thereby improving the accuracy of defrost judgment and, in turn, the refrigerator's defrost efficiency.

[0081] Specifically, the refrigerator determines the equivalent ambient temperature based on the ambient temperature, including: when the actual ambient temperature of the refrigerator is greater than or equal to the first temperature and less than the second temperature, determining the ambient temperature as the first temperature. When the actual ambient temperature of the refrigerator is greater than or equal to the second temperature, determining the ambient temperature as the second temperature. The first temperature is less than the second temperature. Specifically, the first temperature may be 20°C, and the second temperature may be 32°C.

[0082] In this way, if there is no external smart home appliance in the same room as the refrigerator, it is helpful to more accurately convert the ambient temperature into an equivalent ambient temperature, and thus obtain a more accurate equivalent operating time of the refrigerator.

[0083] Specifically, the refrigerator determines the equivalent operating time of the refrigerator based on the equivalent ambient temperature, ambient humidity, evaporator temperature, equivalent door opening time of the refrigerator, and the accumulated actual operating time of the refrigerator, including:

[0084] Refrigerator calculation Tmax=Ty+(Tw1-Tz1)×Tr1×Tk1+(Tw2-Tz2)×Q×Tr2×Tk2+(Tw3-Tz3)×Q×Tr3×Tk3+…+(Tw n -Tzn )×Tr n ×Tk n Among them, Tk i is the equivalent door opening time of the refrigerator door for the i-th time. i Tr is the ambient temperature sent by the external smart home appliance when the refrigerator door is opened for the i-th time. i Tz is the ambient humidity sent by the external smart home appliance when the refrigerator door is opened for the i-th time. i is the evaporator temperature when the refrigerator door is opened for the i-th time. Ty is the cumulative actual operating time of the refrigerator. Tmax is the equivalent operating time of the refrigerator. Q is a fixed value coefficient.

[0085] This helps more accurately convert the equivalent ambient temperature, ambient humidity, evaporator temperature, equivalent door-opening time, and accumulated actual refrigerator operating time into the refrigerator's equivalent operating time. This also helps more accurately determine when the refrigerator triggers defrost mode, taking into account the situation where refrigerators without ambient temperature and humidity sensors are not linked to external smart home appliances. This improves the accuracy of defrost judgment and, in turn, improves the refrigerator's defrost efficiency.

[0086] Optionally, the refrigerator determines the moment when the refrigerator triggers the defrost mode based on the relationship between the equivalent operating time and the defrost time threshold, including: the refrigerator determines the moment when the equivalent operating time is equal to the defrost time threshold as the moment when the refrigerator triggers the defrost mode.

[0087] In this way, the moment when the equivalent operating time, which represents the influence of ambient temperature and humidity and external smart home appliances on the degree of frost, is equal to the defrost time threshold is used as the moment when the refrigerator triggers the defrost mode, which is conducive to improving the accuracy of defrost judgment and thus improving the defrost efficiency of the refrigerator.

[0088] Optionally, the refrigerator determines the moment when the refrigerator triggers the defrost mode based on the relationship between the equivalent operating time and the defrost time threshold, and further includes: when the type of external smart home appliance in the same room as the refrigerator is a gas stove, the refrigerator determines whether the gas stove is stopped or in the defrost mode. If the gas stove is stopped and the refrigerator is not in the defrost mode, the refrigerator determines the moment when the equivalent operating time equals the defrost time threshold as the moment when the refrigerator triggers the defrost mode. If the gas stove is stopped and in the defrost mode, the refrigerator controls the refrigerator to remain in the defrost mode.

[0089] In this case, if the external smart appliance in the same room as the refrigerator is a gas stove and the stove is in operation, the moisture content in the air will continue to rise. The ambient temperature and humidity data will not be updated in a timely manner, resulting in a delayed judgment and the refrigerator's defrost mode not being triggered. If the gas stove is stopped and the refrigerator is not in defrost mode, defrost mode can be triggered. If the gas stove is stopped and the refrigerator is in defrost mode, defrost mode will remain in operation. This helps improve the accuracy of defrost judgment and, in turn, the refrigerator's defrost efficiency.

[0090] Combine Figure 2 As shown, the embodiment of the present disclosure provides another method for defrosting a refrigerator, comprising:

[0091] S201: The refrigerator determines whether there is an external smart home appliance device in the same room as the refrigerator.

[0092] S202: When there is an external smart home appliance in the same room as the refrigerator, the refrigerator receives the ambient temperature, ambient humidity, and operating time of the external smart home appliance sent by the external smart home appliance in the same room as the refrigerator.

[0093] In step S203 , the refrigerator determines the equivalent operating time of the refrigerator based on the ambient temperature, ambient humidity, evaporator temperature, operating time of external smart home appliances, equivalent door opening time of the refrigerator, and accumulated actual operating time of the refrigerator.

[0094] S204: In the absence of any external smart home appliance in the same room as the refrigerator, the refrigerator receives the ambient temperature and humidity sent by the third-party platform.

[0095] S205: The refrigerator determines the equivalent operating time of the refrigerator based on the ambient temperature, ambient humidity, evaporator temperature, equivalent door opening time of the refrigerator, and the accumulated actual operating time of the refrigerator.

[0096] S206: The refrigerator determines the time when the refrigerator triggers the defrost mode according to the relationship between the equivalent operating time and the defrost time threshold.

[0097] Using the method for defrosting a refrigerator provided by an embodiment of the present disclosure, a refrigerator without an ambient temperature and humidity sensor receives ambient temperature, ambient humidity, and external smart appliance operating time transmitted by an external smart appliance in the same room as the refrigerator. The ambient temperature, ambient humidity, external smart appliance operating time, the refrigerator's equivalent door opening time, and the refrigerator's accumulated actual operating time are converted into the refrigerator's equivalent operating time. The refrigerator's equivalent operating time is helpful in more accurately and visually reflecting the impact of ambient temperature and humidity and external smart appliances on the degree of frost. The time when the refrigerator triggers the defrost mode is determined based on the relationship between the equivalent operating time and the defrost time threshold. In this way, obtaining defrost-related temperature and humidity data and the external smart appliance operating time through the external smart appliance is helpful in more accurately determining the time when the refrigerator triggers the defrost mode, thereby improving the accuracy of defrost judgment and further improving the refrigerator's defrost efficiency. If there is no external smart appliance in the same room as the refrigerator, the refrigerator's equivalent operating time is determined based on the ambient temperature and humidity transmitted by the third-party platform, the refrigerator's own evaporator temperature, the equivalent door opening time, and the accumulated actual operating time. This is beneficial for more accurately determining the moment when the refrigerator triggers the defrost mode, taking into account the situation where the refrigerator does not have an ambient temperature and humidity sensor and is not linked to an external smart home appliance, thereby improving the accuracy of the defrost judgment and further improving the defrost efficiency of the refrigerator.

[0098] Combine Figure 3 As shown, the embodiment of the present disclosure provides another method for defrosting a refrigerator, comprising:

[0099] S301, the refrigerator receives the ambient temperature, ambient humidity, and operating time of the external smart home appliance sent by the external smart home appliance in the same room as the refrigerator.

[0100] S302, the refrigerator determines the equivalent operating time of the refrigerator based on the ambient temperature, ambient humidity, evaporator temperature, operating time of external smart home appliances, equivalent door opening time of the refrigerator, and the accumulated actual operating time of the refrigerator.

[0101] S303, when the type of the external smart home appliance in the same room as the refrigerator is a non-gas stove, the moment when the equivalent operating time is equal to the defrost time threshold is determined as the moment when the refrigerator triggers the defrost mode.

[0102] S304: When the external smart home appliance in the same room as the refrigerator is a gas stove, the refrigerator determines whether the gas stove is stopped or in a defrost mode.

[0103] S305 , when the working state of the gas stove is stopped and the refrigerator is not in the defrost mode, the moment when the equivalent operating time is equal to the defrost time threshold is determined as the moment when the refrigerator triggers the defrost mode.

[0104] S306, when the working state of the gas stove is that the refrigerator stops running and is in the defrost mode, controlling the refrigerator to continue to maintain the defrost mode.

[0105] Using the refrigerator defrosting method provided by the embodiments of the present disclosure, a refrigerator without an ambient temperature and humidity sensor receives ambient temperature, humidity, and external smart appliance operating time from an external smart appliance in the same room as the refrigerator. The method then converts the ambient temperature, humidity, external smart appliance operating time, the refrigerator's equivalent door open time, and the refrigerator's accumulated actual operating time into the refrigerator's equivalent operating time. The refrigerator's equivalent operating time more accurately and visually reflects the impact of ambient temperature and humidity and external smart appliances on frost formation. The moment when the equivalent operating time, representing the impact of ambient temperature and humidity and external smart appliances on frost formation, reaches a defrost time threshold is used as the moment when the refrigerator triggers defrost mode, thereby improving the accuracy of defrost determination and, consequently, the refrigerator's defrost efficiency. If the external smart appliance in the same room as the refrigerator is a gas stove and the gas stove is in operation, this indicates that the moisture content in the air is still rising. At this time, the ambient temperature and humidity data will not be updated in a timely manner, resulting in a delayed determination and, in this case, the refrigerator's defrost mode will not be triggered. If the gas stove is stopped and the refrigerator is not in defrost mode, the refrigerator's defrost mode can be triggered. If the gas stove is stopped and the refrigerator is in defrost mode, the defrost mode will remain in effect. This helps improve the accuracy of defrost determination and, in turn, improves the refrigerator's defrost efficiency. By acquiring defrost-related temperature and humidity data and the operating time of the external smart home appliance through the external smart home appliance, it is possible to more accurately determine the time when the refrigerator's defrost mode is triggered, thereby improving the accuracy of defrost determination and, in turn, improving the refrigerator's defrost efficiency.

[0106] Combine Figure 4 As shown, the embodiment of the present disclosure provides another method for defrosting a refrigerator, comprising:

[0107] S401, the refrigerator receives the ambient temperature, ambient humidity, and operating time of the external smart home appliance sent by the external smart home appliance in the same room as the refrigerator.

[0108] S402, the refrigerator is located in the same room with the refrigerator according to the type of external smart home appliance, Tk tempi and the operating time of the i-th external smart home appliance to determine Tk i .

[0109] S403, refrigerator according to Tw i Tr i 、Tz i 、Tk i, Ty, determine Tmax.

[0110] S404: The refrigerator determines the time when the refrigerator triggers the defrost mode according to the relationship between Tmax and the defrost time threshold.

[0111] Among them, Tmax is the equivalent operating time. tempi Tk is the actual door opening time when the refrigerator is opened for the i-th time. i = is the equivalent opening time of the refrigerator door when it is opened for the i-th time. The running time of the i-th external smart home appliance is the running time of the external smart home appliance when the refrigerator door is opened for the i-th time. i Tr is the ambient temperature sent by the external smart home appliance when the refrigerator door is opened for the i-th time. i Tz is the ambient humidity sent by the external smart home appliance when the refrigerator door is opened for the i-th time; i is the evaporator temperature when the refrigerator door is opened for the i-th time. i = 1, 2, ..., n, where n is the total number of times the refrigerator door is opened.

[0112] The method for defrosting a refrigerator provided by the embodiment of the present disclosure first converts the type of external smart home appliance in the same room as the refrigerator, the actual door opening time of the refrigerator each time the door is opened, and the operating time of the corresponding external smart home appliance into the equivalent door opening time of the corresponding refrigerator. The equivalent door opening time of the refrigerator is conducive to more accurately and visually reflecting the impact of the ambient temperature and humidity and the external smart home appliance on the degree of frost. Then, the equivalent operating time of the refrigerator is converted based on the ambient temperature, ambient humidity, equivalent door opening time, the refrigerator's own evaporator temperature, and the accumulated actual operating time of the refrigerator received each time. The equivalent operating time of the refrigerator is conducive to more accurately and visually reflecting the impact of the ambient temperature and humidity and the external smart home appliance on the degree of frost. This is conducive to more accurately determining the moment when the refrigerator triggers the defrost mode, thereby improving the accuracy of the defrost judgment, and further improving the defrost efficiency of the refrigerator.

[0113] Combine Figure 5 As shown, the embodiment of the present disclosure provides another method for defrosting a refrigerator, comprising:

[0114] S501, the refrigerator receives the ambient temperature, ambient humidity, and operating time of the external smart home appliance sent by the external smart home appliance in the same room as the refrigerator.

[0115] S502: When the external smart home appliance in the same room as the refrigerator is a gas stove, the refrigerator is tempi and the running time of the i-th gas stove, determine Tk i .or,

[0116] S503: When the external smart home appliance in the same room as the refrigerator is an air conditioner, the refrigerator is configured to receive the following information based on the operating mode of the air conditioner, Tk tempi and the running time of the i-th air conditioner, determine Tk i .or,

[0117] S504: When the external smart home appliance in the same room as the refrigerator is a humidifier, the refrigerator is tempi and the running time of the i-th humidifier, determine Tk i .

[0118] S505, refrigerator according to Tw i Tr i 、Tz i 、Tk i , Ty, determine Tmax.

[0119] S506: The refrigerator determines the time when the refrigerator triggers the defrost mode according to the relationship between Tmax and the defrost time threshold.

[0120] Among them, Tmax is the equivalent operating time. tempi Tk is the actual door opening time when the refrigerator is opened for the i-th time. i = i is the equivalent door opening time of the refrigerator door being opened for the i-th time. The i-th gas stove operating time is the operating time of the gas stove when the refrigerator door is opened for the i-th time. The i-th air conditioner operating time is the operating time of the air conditioner when the refrigerator door is opened for the i-th time. The i-th humidifier operating time is the operating time of the humidifier when the refrigerator door is opened for the i-th time. Tw i Tr is the ambient temperature sent by the external smart home appliance when the refrigerator door is opened for the i-th time. i Tz is the ambient humidity sent by the external smart home appliance when the refrigerator door is opened for the i-th time. i is the evaporator temperature when the refrigerator door is opened for the i-th time. i = 1, 2, ..., n, where n is the total number of times the refrigerator door is opened.

[0121] Using the refrigerator defrosting method provided by the embodiment of the present disclosure, if the external smart home appliance in the same room as the refrigerator is a gas stove, the actual door opening time each time the refrigerator door is opened and the corresponding gas stove operating time are converted into the corresponding refrigerator equivalent door opening time. The refrigerator equivalent door opening time is conducive to more accurately and visually reflecting the impact of ambient temperature and humidity and the gas stove on the degree of frost. If the external smart home appliance in the same room as the refrigerator is an air conditioner, the operating mode of the air conditioner, the actual door opening time each time the refrigerator door is opened and the corresponding air conditioner operating time are converted into the corresponding refrigerator equivalent door opening time. The refrigerator equivalent door opening time is conducive to more accurately and visually reflecting the impact of ambient temperature and humidity and the air conditioner on the degree of frost. If the refrigerator is located in the same room as a humidifier, the actual door opening time and the corresponding humidifier operating time are converted into the equivalent door opening time of the refrigerator. This equivalent door opening time helps to more accurately and visually reflect the impact of ambient temperature, humidity, and humidifier on frost formation. This helps to more accurately determine when the refrigerator triggers defrost mode, thereby improving the accuracy of defrost judgment and ultimately the refrigerator's defrost efficiency.
