[0030] At present, with the improvement of people's living standards, refrigerators have become an indispensable household appliance in the family. In order to ensure the freshness of food, a large amount of fresh fruits and vegetables, dairy products and other foods are stored in the refrigerator's cold storage room. The temperature of the refrigerator for refrigeration and preservation is basically maintained at around 5°C, while the temperature of the human gastrointestinal tract is about 36°C. If the food is taken out of the refrigerator and eaten directly, it is easy to cause sudden contraction of gastrointestinal blood vessels and mucosa, reduced secretion of digestive juices and other reactions, leading to gastrointestinal physiological dysfunction and symptoms such as weakened digestive function. Especially for infants and children and those with gastrointestinal disorders, eating food before it returns to the edible temperature will further aggravate the discomfort of the body.

[0031] Most of the related technologies are to place the food at room temperature for natural temperature recovery after taking it out, or to heat it at high temperature before eating it, but neither can meet the urgent needs of users to eat the food immediately after taking it out.

[0032] Combination Figure 1 As shown, the embodiment of the present disclosure provides a refrigerator, comprising: a refrigerating compartment 100 and a rewarming compartment 200. The rewarming compartment 200 is connected to the refrigerating compartment 100 through a first air door 300, and is connected to the external environment through a second air door 400.

[0033] The refrigerator provided by the embodiment of the present disclosure has a rewarming chamber 200 in addition to the conventional refrigerating chamber 100. The rewarming chamber 200 can receive cold air from the refrigerating chamber 100 through the first air door 300 to achieve refrigeration and preservation of food stored therein. At the same time, it can also exchange heat with the external environment through the second air door 400 to help the food stored therein gradually heat up to an edible temperature.

[0034] Optionally, there are multiple second air doors 400. In this way, the embodiment of the present disclosure can perform heat exchange for foods at different positions in the reheating chamber 200, and can distinguish respective reheating strategies, which is conducive to ensuring the eating taste of different foods.

[0035] Optionally, the refrigerator further comprises a refrigeration system for providing cold air to the refrigerating compartment to achieve refrigeration and preservation of food stored therein.

[0036] Optionally, the refrigerator further includes a device for controlling the refrigerator. The device for controlling the refrigerator is electrically connected to the first damper 300 and the second damper 400. In this way, the embodiment of the present disclosure can execute a corresponding control method through the device to more accurately control the closing of the first damper and the opening of the second damper.

[0037] Based on the above refrigerator, combined Figure 2 As shown, the embodiment of the present disclosure provides a method for controlling a refrigerator, comprising:

[0038] S201, in response to a user instruction, the processor determines target closing information of a first damper according to user reservation information.

[0039] S202: The processor determines target opening information of the second damper according to food information in the reheating room.

[0040] S203, the processor controls the first damper to close according to the target closing information, and controls the second damper to open according to the target opening information.

[0041] According to the method for controlling a refrigerator provided by the embodiment of the present disclosure, in addition to the conventional cold storage compartment, the refrigerator is also newly provided with a rewarming compartment, and the rewarming compartment can receive the cold from the cold storage compartment through the first damper to realize the cold storage and fresh-keeping of the food stored therein. At the same time, it can also exchange heat with the external environment through the second damper to assist the food stored therein to gradually heat up to an edible temperature. When receiving a user instruction, the embodiment of the present disclosure responds to it, and determines the target closing information of the first damper by analyzing the user's reservation information, so that the first damper can be closed in time to prevent the cold in the cold storage compartment from continuously penetrating into the rewarming compartment and affecting the food rewarming. At the same time, the embodiment of the present disclosure also analyzes the food information in the rewarming compartment to determine the target opening information of the second damper, so that the properties of the food itself can be taken into account to control the reasonable opening of the second damper, so that these foods can be gradually heated to an edible temperature under the action of the external ambient temperature. On this basis, by controlling the first damper to execute the target closing information and controlling the second damper to execute the target opening information, the embodiment of the present disclosure enables the food in the reheating room to be heated up at an appropriate rate and reach an edible temperature at the time expected by the user, thereby meeting the user's urgent need to eat the food immediately after taking it out.

[0042] Optionally, the reservation information includes a scheduled eating time and a scheduled eating temperature. In this way, the user can set corresponding reservation information, including the scheduled eating time and the scheduled eating temperature, while sending the user command. In response to the above reservation information, the embodiment of the present disclosure can more accurately control the state of the first damper and the second damper, so that the food can meet the user's expectations when it is taken out of the rewarming chamber for eating, thereby facilitating the user's eating experience.

[0043] Optionally, the processor determines the target closing information of the first damper according to the user's reservation information, including: the processor determines the cumulative remaining time according to the user's scheduled eating time and the real-time time; the processor determines the predicted warming time according to the user's scheduled eating temperature and the real-time temperature in the warming room; the processor determines the target closing time of the first damper according to the cumulative remaining time and the predicted warming time. In this way, the embodiment of the present disclosure first determines the cumulative remaining time in combination with the user's scheduled eating time and the current real-time time. Then, the predicted warming time is determined in combination with the user's scheduled eating temperature and the current real-time temperature in the warming room. And by comparing the cumulative remaining time and the predicted warming time, the specific time when the warming room stops refrigeration and preservation is determined, and then the target closing time of the first damper is set. In this way, the first damper can be controlled to close in time to avoid the first damper closing too late to affect the food warming efficiency, resulting in the food failing to return to the scheduled eating temperature when the user takes it out of the warming room.

[0044] Optionally, the processor determines the accumulated remaining time according to the user's scheduled eating time and the real-time time, including: the processor calculates the difference between the user's scheduled eating time and the real-time time to obtain the accumulated remaining time. In this way, the embodiment of the present disclosure can obtain the accumulated remaining time to the scheduled eating time by calculating the difference between the user's scheduled eating time and the current real-time time, thereby assisting in determining the specific time when the rewarming chamber stops refrigeration and preservation, so as to facilitate the reasonable setting of the target closing time of the first damper.

[0045] Optionally, the processor determines the predicted warming time according to the user's scheduled eating temperature and the real-time temperature in the warming room, including: the processor calculates the difference between the user's scheduled eating temperature and the real-time temperature in the warming room to obtain the remaining temperature difference; the processor determines the predicted warming time according to the remaining temperature difference. In this way, the embodiment of the present disclosure can obtain the remaining temperature difference from the scheduled eating temperature by calculating the difference between the user's scheduled eating temperature and the current real-time temperature in the warming room, so as to judge the rough time required for the food temperature to return to the scheduled eating temperature after the first damper is closed, that is, to obtain the corresponding predicted warming time, so as to reasonably set the target closing time of the first damper.

[0046] Optionally, the remaining temperature difference is positively correlated with the predicted temperature recovery time. That is, the larger the remaining temperature difference between the user's scheduled serving temperature and the real-time temperature in the temperature recovery room, the longer the predicted temperature recovery time. In this way, the embodiment of the present disclosure can quickly determine the rough time required for the food temperature to return to the scheduled serving temperature after the first damper is closed by pre-establishing the correlation between the remaining temperature difference and the predicted temperature recovery time, thereby facilitating accurate setting of the target closing time of the first damper.

[0047] Optionally, the processor determines the target closing time of the first damper according to the accumulated remaining time and the predicted warming-back time, including: when the accumulated remaining time is less than or equal to the predicted warming-back time, the processor determines the current time as the target closing time of the first damper; or, when the accumulated remaining time is greater than the predicted warming-back time, the processor determines the target time after the current time and the delay time as the target closing time of the first damper. In this way, the embodiment of the present disclosure can judge the specific time when the warming-back compartment stops refrigeration and preservation by comparing the magnitude relationship between the accumulated remaining time and the predicted warming-back time, and then set the target closing time of the first damper. When the accumulated remaining time is less than or equal to the predicted warming-back time, the food temperature may not have returned to the scheduled eating temperature at the scheduled eating time, so the embodiment of the present disclosure determines the current time as the target closing time of the first damper, and controls the first damper to close immediately to avoid the cold amount from the refrigerated compartment affecting the food warming-back efficiency. Then, the disclosed embodiment can determine the target opening information of the second damper later to appropriately improve the food reheating efficiency, and finally ensure that the food can be returned to the scheduled eating temperature at the scheduled eating time, so as to meet the urgent needs of the user to eat the food immediately after taking it out. When the accumulated remaining time is greater than the predicted reheating time, even if the second damper is opened very little, the food can gradually return to the scheduled eating temperature at the scheduled eating time. Therefore, the disclosed embodiment determines the target time after the delay time after the current time as the target closing time of the first damper, and controls the delayed closing of the first damper, so as to avoid the food from returning to the scheduled eating temperature in advance, so that when the user takes out the food at the scheduled eating time, its temperature has already exceeded the scheduled eating temperature for a long time, which greatly affects the eating taste of the food. Therefore, the disclosed embodiment can make the food return to the scheduled eating temperature when it is just near the scheduled eating time by appropriately delaying the closing of the first damper, which is conducive to ensuring the eating taste of the food and improving the eating experience of the user.

[0048] Optionally, the delay time is positively correlated with the difference between the cumulative remaining time and the predicted temperature return time. That is, the greater the difference between the cumulative remaining time and the predicted temperature return time, the longer the delay time. In this way, the embodiment of the present disclosure can reasonably set the delay time in combination with the difference between the cumulative remaining time and the predicted temperature return time, thereby ensuring that the food can be at the scheduled eating temperature at the scheduled eating time, which is conducive to ensuring the taste of the food and improving the user's eating experience.

[0049] Optionally, the delay time is also related to the target opening information of the second damper. Specifically, in some embodiments, the delay time is positively correlated with the opening degree of the second damper. In this way, the greater the opening degree of the second damper, the faster the actual temperature recovery efficiency of the food is affected by the external ambient temperature, and the shorter the time required to reach the scheduled eating temperature. Therefore, the embodiment of the present disclosure may set a longer delay time to keep the food in a refrigerated and fresh state at the initial control stage, and then close the first damper after the delay time, so as to avoid the food being affected by the external ambient temperature, resulting in its temperature far exceeding the scheduled eating temperature at the scheduled eating time, resulting in a decrease in its taste.

[0050] Optionally, the food information includes the food type and the food weight. In this way, by obtaining the above food information, the embodiment of the present disclosure can further analyze the properties of the food itself, and then consider the impact of the temperature change in the rewarming room on it, so as to more reasonably control the state of the second air door, so that the food can maintain a better taste and a higher nutritional level when it is taken out of the rewarming room for consumption, which is conducive to ensuring the user's eating experience.

[0051] Optionally, the processor determines the target opening information of the second damper according to the food information in the reheating room, including: the processor determines the target opening degree of the second damper according to the type of food in the reheating room. In this way, the embodiment of the present disclosure can take into account the possible impact of the heating rate on different food types, and then determine the adapted heating rate for the actual food type stored in the reheating room, and then control the second damper to open at the corresponding target opening degree. This allows the food to be heated at an appropriate rate to avoid nutrient loss or reduced taste due to too fast or too slow heating.

[0052] Optionally, the processor determines the target opening degree of the second damper according to the type of food in the reheating room, including: when the type of food in the reheating room is cooked food, the target opening degree of the second damper is determined to be the first opening degree; or, when the type of food in the reheating room is fruit and vegetable, the target opening degree of the second damper is determined to be the second opening degree; or, when the type of food in the reheating room is dairy products, the target opening degree of the second damper is determined to be the third opening degree; or, when the type of food in the reheating room is beverage, the target opening degree of the second damper is determined to be the fourth opening degree. Among them, the first opening degree is greater than the second opening degree, the second opening degree is greater than the third opening degree, and the third opening degree is greater than the fourth opening degree. In this way, the embodiment of the present disclosure can set the appropriate opening degree corresponding to the second damper for several common ready-to-eat foods such as cooked food, fruit and vegetable, dairy products and beverages, so that the ready-to-eat foods can be heated at an appropriate rate, which is conducive to avoiding the loss of nutrition caused by too fast reheating or the impact of too slow reheating on the taste.

[0053] Optionally, the disclosed embodiment may include more food types, not limited to the above-mentioned food types. The target opening degree of the second air door may also be reasonably set according to the above-mentioned food types to adapt to the appropriate heating rate, which are not listed here. At the same time, based on the various food types, the refrigerator may make corresponding functional adjustments.

[0054] Optionally, the processor controls the second damper to open according to the target opening information, including: the processor determines the target opening angle of the second damper according to the target opening degree of the second damper; the processor controls the second damper to rotate to the target opening angle. In this way, the embodiment of the present disclosure can accurately adjust the connection area between the rewarming chamber and the external environment by controlling the second damper to rotate to the target opening angle, so as to reasonably control the heating rate of the food, so that the food can maintain a better taste and a higher nutritional level when it is taken out of the rewarming chamber for consumption.

[0055] Optionally, the processor controls the second damper to open according to the target opening information, including: the processor determines the target opening position of the second damper according to the target opening degree of the second damper; the processor controls the second damper to slide to the target opening position. In this way, the embodiment of the present disclosure can accurately adjust the connection area between the rewarming chamber and the external environment by controlling the second damper to slide to the target opening position, so as to reasonably control the heating rate of the food, so that the food can maintain a better taste and a higher nutritional level when it is taken out of the rewarming chamber for consumption.

[0056] Based on the above refrigerator, combined Figure 3 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0057] S301, in response to a user instruction, the processor determines target closing information of the first damper according to the user's reservation information.

[0058] S302: The processor determines a target opening degree of the second air door according to the type of food in the reheating room.

[0059] S303: The processor corrects the target opening degree of the second air door according to the weight of the food in the reheating room.

[0060] S304, the processor controls the first damper to close according to the target closing information, and controls the second damper to open according to the target opening information.

[0061] According to the method for controlling a refrigerator provided by the embodiment of the present disclosure, in addition to the conventional cold storage compartment, the refrigerator is also newly provided with a rewarming compartment, and the rewarming compartment can receive the cold from the cold storage compartment through the first damper to realize the refrigeration and preservation of the food stored therein. At the same time, heat can be exchanged with the external environment through the second damper to assist the food stored therein to gradually heat up to an edible temperature. When receiving a user instruction, the embodiment of the present disclosure responds to it, and determines the target closing information of the first damper by analyzing the user's reservation information, so that the first damper can be closed in time to prevent the cold in the cold storage compartment from continuously penetrating into the rewarming compartment and affecting the rewarming of the food. At the same time, the embodiment of the present disclosure also obtains the type and weight of food in the rewarming compartment, and then determines and corrects the target opening degree of the second damper accordingly, so that the influence of the heating rate on different food types and food weights can be taken into account. On this basis, by controlling the first damper to execute the target closing information and controlling the second damper to open at a suitable target opening degree, the disclosed embodiment enables the food in the rewarming room to be heated at a suitable rate, so that the food can reach the edible temperature at the time expected by the user, thereby meeting the urgent need of the user to eat the food immediately after taking it out. At the same time, it can also avoid the loss of nutrition or the decline of the eating taste caused by the food warming up too fast or too slow, which is conducive to maintaining a better eating taste and a higher nutritional level when the food is taken out of the rewarming room for consumption.

[0062] Optionally, the processor corrects the target opening of the second damper according to the weight of the food in the rewarming room, including: the processor determines the reference weight according to the type of food in the rewarming room; the processor determines the correction coefficient of the target opening according to the ratio of the weight of the food in the rewarming room to the reference weight; the processor corrects the target opening of the second damper according to the correction coefficient. In this way, the embodiment of the present disclosure can set a reasonable correction coefficient for the initial target opening in combination with the ratio of the weight of the food in the rewarming room to the reference weight corresponding to the food type, so as to take into account the influence of the food weight on the required heating rate. The correction coefficient is used to reasonably correct the target opening of the second damper to accurately control the connection area between the rewarming room and the external environment, so as to reasonably fine-tune the heating rate to ensure that the food meets the user's expectations when it is taken out of the rewarming room for consumption, which is conducive to ensuring the user's eating experience.

[0063] Optionally, the correction coefficient of the target opening degree is positively correlated with the ratio of the weight of the food in the rewarming room to the reference weight. Specifically, in some embodiments, the correction coefficient of the target opening degree is equal to the ratio of the weight of the food in the rewarming room to the reference weight. In this way, when the ratio of the weight of the food in the rewarming room to the reference weight is larger, it indicates that the amount of food stored in the rewarming room may be too much, and a slightly higher heating rate is required to ensure that the food can reach the edible temperature at the time expected by the user. Therefore, the embodiment of the present disclosure reasonably corrects the target opening degree of the second damper by setting a correction coefficient slightly greater than 1, so as to appropriately increase the connection area between the rewarming room and the external environment, thereby slightly improving the rewarming efficiency, so as to ensure that the food can meet the user's expectations when it is taken out of the rewarming room for consumption, which is conducive to ensuring the user's eating experience.

[0064] Optionally, the processor corrects the target opening degree of the second damper according to the correction coefficient, including: the processor multiplies the correction coefficient by the target opening degree to obtain the corrected target opening degree of the second damper. In this way, the embodiment of the present disclosure can obtain the corrected target opening degree of the second damper by multiplying the correction coefficient by the initial target opening degree. In this way, the connection area between the rewarming chamber and the external environment can be accurately controlled to reasonably fine-tune the heating rate to ensure that the food can meet the user's expectations when it is taken out of the rewarming chamber for consumption, which is conducive to ensuring the user's eating experience.

[0065] Based on the above refrigerator, combined Figure 4 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0066] S401, in response to a user instruction, the processor determines target closing information of the first damper according to the user's reservation information.

[0067] S402: The processor determines a target opening degree of the second air door according to the type of food in the reheating room.

[0068] S403: The processor determines a target opening time of the second damper according to the target opening degree of the second damper.

[0069] S404, the processor controls the first damper to close according to the target closing information, and controls the second damper to open according to the target opening information.

[0070] According to the method for controlling a refrigerator provided by the embodiment of the present disclosure, in addition to the conventional cold storage compartment, the refrigerator is also newly provided with a rewarming compartment, and the rewarming compartment can receive the cold from the cold storage compartment through the first damper to realize the cold storage and fresh-keeping of the food stored therein. At the same time, heat can be exchanged with the external environment through the second damper to assist the food stored therein to gradually heat up to an edible temperature. When receiving a user instruction, the embodiment of the present disclosure responds to it, and determines the target closing information of the first damper by analyzing the user's reservation information, so that the first damper can be closed in time to prevent the cold in the cold storage compartment from continuously penetrating into the rewarming compartment and affecting the food rewarming. At the same time, the embodiment of the present disclosure also obtains the type of food in the rewarming compartment, and then determines the target opening degree of the second damper accordingly, so that the influence of the heating rate on different food types can be considered. In addition, the embodiment of the present disclosure can also reasonably set the target opening time in combination with the target opening degree of the second damper to control the second damper to open at an appropriate time, so as to ensure that the food can reach the edible temperature at the user's expected time to meet the user's expectations. On this basis, by controlling the first damper to execute the target closing information and controlling the second damper to execute the target opening information, the disclosed embodiment enables the food in the reheating room to be heated at an appropriate rate, so that the food can reach the edible temperature at the time expected by the user, so as to meet the urgent need of the user to eat the food immediately after taking it out. At the same time, it can also avoid the loss of nutrition or the decline of the taste of the food caused by the food reheating too fast or too slow, which is conducive to maintaining a better taste and higher nutritional level when the food is taken out of the reheating room for consumption.

[0071] Optionally, the processor determines the target opening time of the second damper according to the target opening degree of the second damper, including: the processor determines the interval duration according to the target opening degree of the second damper; the processor determines the target opening time of the second damper according to the interval duration and the target closing time of the first damper. In this way, the embodiment of the present disclosure makes the closing time of the first damper staggered with the opening time of the second damper, and controls the second damper to open at the target opening degree for most of the time, so that the food can be warmed up at a suitable heating rate to avoid the loss of nutrition or the decrease of the eating taste caused by the temperature returning too fast or too slow. The second damper is kept closed only within the interval duration after the first damper is closed to allow the food to return to temperature slowly, but since the food temperature is close to the refrigeration temperature at this time, the impact on the subsequent taking out and eating of the food is small. Therefore, while maintaining the better eating taste and higher nutritional level of the food, the embodiment of the present disclosure can reasonably control the opening time of the second damper to ensure that the food can reach the edible temperature at the time expected by the user, thereby helping to meet the urgent needs of the user to eat the food immediately after taking it out.

[0072] Optionally, the interval duration is positively correlated with the target opening degree of the second damper. In this way, the larger the target opening degree of the second damper, the faster the food temperature recovery efficiency, and the shorter the time required to reach the edible temperature. Therefore, the embodiment of the present disclosure can set a longer interval duration to postpone the opening timing of the second damper, thereby preventing the food from returning to the edible temperature too early, resulting in a decrease in the taste when the user takes it out. Therefore, by setting a suitable interval duration, the embodiment of the present disclosure can make the food reach the edible temperature just before the user expects, which is conducive to ensuring the edible taste of the food and improving the user's eating experience.

[0073] It is understandable that, in this embodiment, only one of the interval duration of the second air door opening and the delay duration of the first air door closing needs to be set in combination with the target opening degree of the second air door to meet the user's expectations, thereby ensuring that the food reaches the edible temperature just before the user's expected time, which is conducive to ensuring the taste of the food. Exemplarily, when the processor determines the interval duration of the second air door opening according to the target opening degree of the second air door, it is not necessary to determine the delay duration of the first air door closing in combination with the target opening degree of the second air door, thereby avoiding repeated adjustments that cause the temperature return time to be too short, resulting in the food temperature failing to return to the edible temperature at the user's expected time.

[0074] Optionally, the processor determines the target opening time of the second damper according to the interval time and the target closing time of the first damper, including: the processor determines the target opening time of the second damper as the time after the target closing time of the first damper exceeds the interval time. In this way, the embodiment of the present disclosure makes the closing time of the first damper staggered with the opening time of the second damper, so that the second damper is opened again after the interval time has passed after the first damper is closed. In this way, while maintaining the better taste and higher nutritional level of the food, it is further ensured that the food can reach the edible temperature at the time expected by the user, which is conducive to meeting the urgent need of the user to eat the food immediately after taking it out.

[0075] Based on the above refrigerator, combined Figure 5 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0076] S501, in response to a user instruction, the processor determines target closing information of a first damper according to user reservation information.

[0077] S502: The processor determines target opening information of the second damper according to the food information in the reheating room.

[0078] S503, the processor controls the first damper to close according to the target closing information, and controls the second damper to open according to the target opening information.

[0079] S504, when the difference between the real-time time and the scheduled eating time is greater than or equal to the time difference threshold, and / or the difference between the real-time temperature and the scheduled eating temperature is greater than or equal to the temperature difference threshold, the processor controls the second damper to close and controls the first damper to open.

[0080] According to the method for controlling a refrigerator provided by the embodiment of the present disclosure, in addition to the conventional cold storage compartment, the refrigerator is also newly provided with a rewarming compartment, and the rewarming compartment can receive the cold from the cold storage compartment through the first damper to realize the cold storage and fresh-keeping of the food stored therein. At the same time, it can also exchange heat with the external environment through the second damper to assist the food stored therein to gradually heat up to an edible temperature. When receiving a user instruction, the embodiment of the present disclosure responds to it, and determines the target closing information of the first damper by analyzing the user's reservation information, so that the first damper can be closed in time to prevent the cold in the cold storage compartment from continuously penetrating into the rewarming compartment and affecting the food rewarming. At the same time, the embodiment of the present disclosure also analyzes the food information in the rewarming compartment to determine the target opening information of the second damper, so that the properties of the food itself can be taken into account to control the reasonable opening of the second damper, so that these foods can be gradually heated to an edible temperature under the action of the external ambient temperature. On this basis, by controlling the first damper to execute the target closing information, and controlling the second damper to execute the target opening information, the embodiment of the present disclosure enables the food in the rewarming room to be heated at an appropriate rate, and to reach the edible temperature at the user's expected time, thereby meeting the user's urgent need to eat the food immediately after taking it out. In addition, considering the situation where the user does not respond, the embodiment of the present disclosure also continuously monitors the real-time time and the real-time temperature. When the difference between the real-time time and the scheduled eating time is greater than or equal to the time difference threshold, and / or the difference between the real-time temperature and the scheduled eating temperature is greater than or equal to the temperature difference threshold, the user may forget the reservation information, so the embodiment of the present disclosure timely adjusts the state of the first damper and the second damper. By controlling the second damper to close and the first damper to open, the rewarming room is switched to a refrigerated and fresh-keeping state, so that the food can be prevented from spoiling when the user forgets to take out the edible food, which is conducive to improving the reliability of food storage.

[0081] Optionally, the time difference threshold can be set in combination with the outdoor ambient temperature to prevent food from being spoiled due to being in a room temperature environment for a long time. Preferably, the time difference threshold is 2 hours. The time difference threshold can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value such as 1 hour or 3 hours.

[0082] Optionally, the temperature difference threshold can be set in combination with the outdoor ambient temperature to prevent food from being spoiled due to being in a high room temperature environment. Preferably, the temperature difference threshold is 5°C. The temperature difference threshold can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value such as 3°C or 8°C.
