[0052] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0053] In the description of the present application, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0054] In the description of this application, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0055] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0056] In some cases, in order to keep food such as meat fresh, it is necessary to freeze it in a refrigerator and thaw it in advance before cooking, for example, taking the food out of the freezer in advance and putting it in a refrigerator or thawing room for thawing. However, for the current thawing method, the thawing speed is often constant, that is, the thawing power in each time period is the same, so the electricity cost generated by the current thawing method is often high, which is not conducive to energy conservation and emission reduction.

[0057] Based on the above situation, the embodiments of the present application propose a food thawing control method, a thawing box, a refrigerator and a computer-readable storage medium, aiming to save electricity costs and achieve energy conservation and emission reduction.

[0058] The following is a further description of various embodiments of the food thawing control method of the present application in conjunction with the accompanying drawings.

[0059] like Figure 1 As shown, Figure 1 1 is a flow chart of a food thawing control method provided by an embodiment of the present application. The food thawing control method may include but is not limited to step S110, step S120, step S130, step S140 and step S150.

[0060] Step S110, obtaining the current time, the expected thawing completion time, and the first estimated thawing time at the first thawing speed;

[0061] Step S120, determining an estimated thawing completion time according to the current time and the first estimated thawing duration;

[0062] Step S130: when the estimated thawing completion time is earlier than the expected thawing completion time, determining a thawing reference time period according to the expected thawing completion time and the first estimated thawing duration;

[0063] Step S140, determining the thawing start time and thawing speed according to the distribution of the peak and valley time periods of electricity consumption within the thawing reference time period;

[0064] Step S150: Control the thawing box to thaw the food based on the thawing start time and the thawing speed.

[0065] In one embodiment, after receiving the thawing request, first, the embodiment of the present application will obtain the current time and the expected thawing completion time corresponding to the time when the user expects the food to be thawed, and will also analyze the first estimated thawing time required for the food to be thawed at the first thawing speed; then, the embodiment of the present application can accumulate the current time and the first estimated thawing time to calculate the estimated thawing completion time; then, the embodiment of the present application will compare the estimated thawing completion time with the expected thawing completion time. If the estimated thawing completion time is earlier than the expected thawing completion time, it indicates that the food can be thawed in advance at the first thawing speed. Freezing is completed, that is, the food will have sufficient time to thaw at the first thawing speed. In this regard, the embodiment of the present application will calculate a thawing reference time period based on the expected thawing completion time and the first estimated thawing time; then, for the thawing reference time period, the embodiment of the present application will combine the local peak-shifting electricity policy to analyze the distribution of peak and valley time periods within the thawing reference time period, and determine the thawing start time and thawing speed of the food according to the distribution; finally, when the time reaches the above-mentioned thawing start time, the embodiment of the present application will start the thawing function and thaw the food according to the thawing speed obtained above.

[0066] According to the technical solution of the embodiment of the present application, since the electricity prices during peak electricity consumption periods and off-peak electricity consumption periods are different, and the embodiment of the present application can flexibly adjust the thawing start time and thawing speed according to the local peak-shifting electricity consumption policy when there is sufficient thawing time, it is possible to reduce electricity costs as much as possible while ensuring the thawing timeliness, thereby achieving energy conservation and emission reduction.

[0067] It should be noted that, for the above-mentioned thawing speed, if the thawing speed is faster, the corresponding thawing power will be greater; on the contrary, if the thawing speed is slower, the corresponding thawing power will be smaller. Therefore, if the thawing time is sufficient, the embodiment of the present application can thaw at a slower thawing speed or not thaw during the peak power consumption period, and thaw at a faster thawing speed during the low power consumption period, thereby reducing the power consumption during the peak power consumption period and increasing the power consumption during the low power consumption period, thereby achieving a reduction in power consumption costs and energy conservation and emission reduction.

[0068] In addition, it should be noted that when the embodiment of the present application starts thawing at the obtained thawing speed at the thawing start time, the thawing of the food can be completed near the expected thawing completion time corresponding to the time when the user expects the food to be thawed, thereby avoiding the food from being thawed too early or too late.

[0069] In addition, it should be noted that the above-mentioned thawing request can be set by the user. Specifically, the thawing request can be a thawing request sent by the user in real time, or a thawing request automatically generated at a fixed time set in advance. The embodiment of the present application does not specifically limit the generation method of the above-mentioned thawing request.

[0070] In addition, it should be noted that the above-mentioned current time may be the time corresponding to when the thawing request is received.

[0071] In addition, it should be noted that the above-mentioned expected thawing completion time can be a time point directly set by the user, or it can be a recommended time recommended to the user by the system based on the information of the current ingredients to be thawed, or it can be a regular eating time set by the user in advance. The embodiment of the present application does not specifically limit the setting method of the above-mentioned expected thawing completion time.

[0072] In addition, it should be noted that the above-mentioned first thawing speed may refer to the normal thawing speed commonly used by the system to thaw food, or it may be other faster or slower thawing speeds. The embodiment of the present application does not specifically limit the value of the above-mentioned first thawing speed.

[0073] In addition, it should be noted that the first estimated thawing time mentioned above can be estimated based on the information of the current food to be thawed and the first thawing speed analysis, wherein the information of the food to be thawed may include but is not limited to the name of the object, category, weight, quantity, volume or unit, etc. For example, different categories of meat have different estimated thawing times; the heavier the weight of the food, the longer the estimated thawing time; the more the quantity of food, the longer the estimated thawing time.

[0074] In addition, it should be noted that the method of obtaining the information of the ingredients to be thawed may be but is not limited to a combination of any one or more of the following methods: manual entry by the user, image recognition after camera shooting of the thawing area, user voice entry, weighing sensor detection of the thawing area, automatic recognition of RFID / NFC electronic tags carried on objects, etc.

[0075] In addition, if Figure 2 As shown, Figure 2 2 is a flowchart of a food thawing control method provided by another embodiment of the present application. After performing the above step S120 of determining the estimated thawing completion time according to the current time and the first estimated thawing duration, the food thawing control method of the embodiment of the present application may also include but is not limited to step S210 and step S220.

[0076] Step S210, when the estimated thawing completion time is not earlier than the expected thawing completion time, thawing at a second thawing speed, wherein the second thawing speed is greater than the first thawing speed;

[0077] Step S220: obtaining a second estimated thawing time at a second thawing speed, and determining an actual thawing completion time according to the current time and the second estimated thawing time.

[0078] In one embodiment, after comparing the estimated thawing completion time with the expected thawing completion time, if the estimated thawing completion time is not earlier than the expected thawing completion time, it indicates that the food cannot be thawed in advance at the first thawing speed, that is, the food cannot be thawed before the user's expected thawing completion time. In this regard, the embodiment of the present application will use a second thawing speed with a faster thawing speed to thaw the food, that is, accelerate the thawing; at the same time, the embodiment of the present application will also analyze the second estimated thawing time required for the food to complete the thawing at the second thawing speed, and accumulate the current time and the second estimated thawing time to calculate the actual thawing completion time, and push the actual thawing completion time to the user.

[0079] It should be noted that, in the case of insufficient thawing time, the embodiment of the present application will thaw the food at a second thawing speed with a faster thawing speed, without considering the local peak-shifting electricity policy, so as to ensure the user's thawing time requirement as much as possible.

[0080] In addition, it should be noted that the above-mentioned second thawing speed may refer to the rapid thawing speed of the system for thawing food, and the embodiment of the present application does not specifically limit the numerical value of the above-mentioned second thawing speed.

[0081] In addition, it should be noted that the second estimated thawing time mentioned above can be estimated based on the information of the current food to be thawed and the second thawing speed analysis, wherein the information of the food to be thawed may include but is not limited to the name of the object, category, weight, quantity, volume or unit, etc. For example, different categories of meat have different estimated thawing times; the heavier the weight of the food, the longer the estimated thawing time; the more the quantity of food, the longer the estimated thawing time.

[0082] It should be noted that the method for determining the reference time period for thawing in the above step S130 may include but is not limited to: Figure 3 or Figure 4 The two implementations shown are as follows:

[0083] like Figure 3 As shown, Figure 3 The flowchart of the food thawing control method provided by another embodiment of the present application is as follows. The above step S130 of determining the thawing reference time period according to the expected thawing completion time and the first estimated thawing duration may include but is not limited to step S310, step S320 and step S330.

[0084] Step S310, obtaining a first time increment increased by thawing at a third thawing speed relative to the first thawing speed, wherein the third thawing speed is less than the first thawing speed;

[0085] Step S320: subtract the first estimated thawing time and the first time increment from the expected thawing completion time to obtain a first reference time;

[0086] Step S330: taking the time period between the first reference time and the expected thawing completion time as a thawing reference time period.

[0087] In one embodiment, when the system also has a third thawing speed with a slower thawing speed, since the third thawing speed is slower than the first thawing speed, the duration of thawing at the third thawing speed will be longer than the duration of thawing at the first thawing speed, for example, the first time increment is increased; then, in order to subsequently thaw based on the third thawing speed, the embodiment of the present application can use the difference between the expected thawing completion time, the first estimated thawing time, and the first time increment as the first reference time, and use the time period between the first reference time and the expected thawing completion time as the thawing reference time period.

[0088] It should be noted that after subtracting the first estimated thawing time from the expected thawing completion time, the reason for further subtracting the first time increment is that if thawing can be performed based on the third thawing speed subsequently, thawing needs to be performed in advance by the first time increment. Therefore, the embodiment of the present application uses the difference between the expected thawing completion time, the first estimated thawing time and the first time increment as the starting time of the thawing reference time period.

[0089] In addition, it should be noted that the third thawing speed mentioned above may refer to the decelerated thawing speed of the system for thawing food. The embodiment of the present application does not specifically limit the numerical value of the third thawing speed mentioned above.

[0090] In addition, it should be noted that the first time increment mentioned above refers to a time increment with a positive index value.

[0091] like Figure 4 As shown, Figure 4 The flowchart of the food thawing control method provided by another embodiment of the present application is as follows. Regarding the above step S130 of determining the thawing reference time period according to the expected thawing completion time and the first estimated thawing duration, it may include but is not limited to step S410 and step S420.

[0092] Step S410, subtracting the first estimated thawing time from the expected thawing completion time to obtain a second reference time;

[0093] Step S420: taking the time period between the second reference time and the expected thawing completion time as a thawing reference time period.

[0094] In one embodiment, when the system does not have a third thawing speed with a slower thawing speed, that is, when the system does not have a decelerated thawing function, the embodiment of the present application can directly use the difference between the expected thawing completion time and the first estimated thawing time as the second reference time, and use the time period between the second reference time and the expected thawing completion time as the thawing reference time period.

[0095] It should be noted that, in the case where the system does not have a third thawing speed with a slower thawing speed, in addition to the above Figure 4 In addition to determining the unfreezing reference time period by Figure 3 The thawing reference time period is determined in a manner which is not specifically limited in the embodiments of the present application.

[0096] In addition, if Figure 5 As shown, Figure 5 is a flow chart of a food thawing control method provided by another embodiment of the present application. Figure 3 and Figure 4 The two implementations shown, regarding the above step S140 of determining the thawing start time and the thawing speed according to the distribution of the peak and valley time periods of electricity consumption within the thawing reference time period, may include but are not limited to step S510 and step S520.

[0097] Step S510, obtaining a second time increment reduced by thawing at a second thawing speed relative to the first thawing speed, wherein the second thawing speed is greater than the first thawing speed;

[0098] Step S520: When the thawing reference time period includes a low-power consumption time period, the first estimated thawing duration is subtracted from the expected thawing completion time and the second time increment is added to obtain the thawing start time, and the second thawing speed is used as the thawing speed.

[0099] In one embodiment, after determining the thawing reference time period, for the thawing reference time period, the embodiment of the present application will analyze the distribution of peak and valley time periods within the thawing reference time period in combination with the local peak-shifting electricity consumption policy. If the valley time period within the thawing reference time period is longer, that is, the valley time period is greater than the preset duration, it indicates that the embodiment of the present application can adopt a fast thawing method, that is, a thawing method using the second thawing speed.

[0100] At the same time, after determining that the fast thawing method can be used, the embodiment of the present application also needs to determine a specific thawing start time, which is as follows: since the second thawing speed is faster than the first thawing speed, the duration of thawing at the second thawing speed will be shorter than the duration of thawing at the first thawing speed, for example, the second time increment is reduced. In this regard, the embodiment of the present application can delay the second time increment and then start thawing based on the difference between the expected thawing completion time and the first expected thawing time, that is, the expected thawing completion time minus the first expected thawing time and plus the second time increment as the thawing start time. Finally, when the time reaches the above-mentioned thawing start time, the embodiment of the present application will start the thawing function and thaw the food according to the second thawing speed.

[0101] In addition, it should be noted that the second time increment mentioned above refers to a time increment with a positive index value.

[0102] In addition, if Figure 6 As shown, Figure 6 is a flow chart of a food thawing control method provided by another embodiment of the present application. Figure 3 In the implementation shown, regarding the above step S140 of determining the thawing start time and the thawing speed according to the distribution of the peak and valley time periods of electricity consumption within the thawing reference time period, it can also include but is not limited to step S610 and step S620.

[0103] Step S610: when the unfreezing reference time period does not include a low-power consumption time period;

[0104] Step S620: Determine the thawing start time and the thawing speed according to the first reference time and the current time.

[0105] In one embodiment, when the system also has a third thawing speed with a slower thawing speed, after determining the thawing reference time period, for the thawing reference time period, the embodiment of the present application will analyze the distribution of peak and valley time periods within the thawing reference time period in combination with the local peak-shifting electricity policy. If the thawing reference time period does not include a valley time period or the valley time period is short, that is, the valley time period is less than the preset duration, it indicates that it is difficult for the embodiment of the present application to adopt a quick thawing method, that is, it can only use the first thawing speed or the third thawing speed for thawing.

[0106] At the same time, after determining that only the normal thawing method or the deceleration thawing method can be used, the embodiment of the present application also needs to select between the normal thawing method and the deceleration thawing method. Specifically, the first reference time and the current time can be compared, and then the normal thawing method or the deceleration thawing method can be determined based on the comparison result. In addition, after determining the thawing method, the embodiment of the present application will also set the thawing start time accordingly based on the selected thawing method.

[0107] It should be noted that the above step S620 in which the thawing start time and the thawing speed are determined according to the first reference time and the current time may include but is not limited to: Figure 7 or Figure 8 The two implementations shown are as follows:

[0108] like Figure 7 As shown, Figure 7 The flowchart of the food thawing control method provided by another embodiment of the present application is as follows. Regarding the above step S620 of determining the thawing start time and the thawing speed according to the first reference time and the current time, it may include but is not limited to step S710 and step S720.

[0109] Step S710: when the first reference time is not earlier than the current time;

[0110] Step S720: taking the first reference time as the thawing start time, and taking the third thawing speed as the thawing speed.

[0111] like Figure 8 As shown, Figure 8 The flowchart of the food thawing control method provided by another embodiment of the present application is as follows. Regarding the above step S620 of determining the thawing start time and the thawing speed according to the first reference time and the current time, it may include but is not limited to step S810 and step S820.

[0112] Step S810: when the first reference time is earlier than the current time;

[0113] Step S820: subtract the first estimated thawing time from the expected thawing completion time to obtain the thawing start time, and use the first thawing speed as the thawing speed.

[0114] In one embodiment, regarding the above Figure 6The thawing method selection process and the thawing start time determination process mentioned in the text are specifically as follows: compare the first reference time and the current time, wherein the first reference time is calculated by the difference between the expected thawing completion time, the first estimated thawing duration and the first time increment; if the first reference time is not earlier than the current time, it indicates that the time period between the current time and the expected thawing completion time can include the first time increment, then the deceleration thawing can be adopted at this time, that is, the thawing can be performed at the third thawing speed, and at the same time, the embodiment of the present application can use the first reference time as the thawing start time; if the first reference time is earlier than the current time, it indicates that the time period between the current time and the expected thawing completion time cannot include the first time increment, then only the normal speed thawing can be adopted at this time, that is, the first thawing speed can be adopted for thawing, and at the same time, the embodiment of the present application can use the difference between the expected thawing completion time and the first estimated thawing duration as the thawing start time.

[0115] In addition, if Fig. 9 As shown, Fig. 9 is a flow chart of a food thawing control method provided by another embodiment of the present application. Figure 4 In the implementation shown, regarding the above step S140 of determining the thawing start time and the thawing speed according to the distribution of the peak and valley time periods of electricity consumption within the thawing reference time period, it can also include but is not limited to step S910 and step S920.

[0116] Step S910: when the unfreezing reference time period does not include a low-power consumption time period;

[0117] Step S920: taking the second reference time as the thawing start time, and taking the first thawing speed as the thawing speed.

[0118] In one embodiment, when the system does not have a third thawing speed with a slower thawing speed, after determining the thawing reference time period, for the thawing reference time period, the embodiment of the present application will analyze the distribution of peak and valley time periods within the thawing reference time period in combination with the local peak-shifting electricity policy. If the thawing reference time period does not include a valley time period or the valley time period is short, that is, the valley time period is less than the preset duration, it indicates that it is difficult for the embodiment of the present application to adopt a quick thawing method, that is, it can only adopt the first thawing speed for thawing.

[0119] At the same time, the embodiment of the present application can use the second reference time obtained by subtracting the expected thawing completion time from the first estimated thawing duration as the thawing start time.

[0120] In addition, if Fig.10 As shown, Fig.102 is a flowchart of a food thawing control method provided by another embodiment of the present application. After executing step S150 to control the thawing box to thaw the food based on the thawing start time and the thawing speed, the food thawing control method of the embodiment of the present application may also include but is not limited to steps S1010 and S1020.

[0121] Step S1010, obtaining the regional temperature and target temperature of the thawing area;

[0122] Step S1020: When the area temperature is greater than or equal to the target temperature, thawing is stopped and a thawing completion prompt message is pushed.

[0123] In one embodiment, after starting the thawing function, the embodiment of the present application can detect the regional temperature of the thawing area through a temperature sensor, and then compare the regional temperature with the set target temperature. If the regional temperature is greater than or equal to the target temperature, the embodiment of the present application will stop thawing and prompt the user.

[0124] It should be noted that the above-mentioned target temperature may be a pre-set temperature, and the embodiment of the present application does not specifically limit the value of the target temperature.

[0125] In addition, it should be noted that the embodiment of the present application can push the thawing completion prompt information through screen display, can also push the thawing completion prompt information through voice playback, and can also send the thawing completion prompt information to the user's mobile phone to prompt the user.

[0126] Based on the food thawing control methods of the above-mentioned embodiments, overall embodiments of the food thawing control method of the present application are respectively proposed below.

[0127] like Fig.11 As shown, Fig.11 It is an overall flow chart of a food thawing control method provided by an embodiment of the present application, including but not limited to the following steps S1110 to S1190.

[0128] Step S1110, start;

[0129] Step S1120, determine whether t+Tj≥tm is satisfied, if yes, execute step S1130, otherwise execute step S1140;

[0130] Step S1130, perform fast thawing, remind the user of the estimated thawing completion time ts, and execute step S1190;

[0131] Step S1140, determine whether [(tm-Tj-△T1), tm] contains the off-peak and off-peak period Td, if so, execute step S1150, otherwise execute step S1160;

[0132] Step S1150, accelerating thawing at the time point tm-Tj+△T2, and executing step S1190;

[0133] Step S1160, determine whether tm-Tj-△T1≥t is satisfied, if yes, execute step S1170, otherwise execute step S1180;

[0134] Step S1170, decelerate and thaw at the time point tm-Tj-△T1, and execute step S1190;

[0135] Step S1180, perform normal speed defrosting at the time point tm-Tj, and execute step S1190;

[0136] Step S1190: When the thawing zone reaches the target temperature, thawing is stopped and a thawing completion reminder is sent.

[0137] Among them, for the above Fig.11 The parameters in , starting with capital letters represent time periods, and starting with lowercase letters represent time points; specifically, the current time point is t, i.e. the current time mentioned above; the planned thawing time period Tj, i.e. the first estimated thawing time mentioned above; the planned thawing completion time point tm, i.e. the expected thawing completion time mentioned above; the estimated thawing completion time point ts, i.e. the actual thawing completion time mentioned above; △T1 is the time added by decelerating thawing by staggering the peak period, i.e. the first time increment mentioned above; △T2 is the time saved by accelerating thawing by staggering the trough period, i.e. the second time increment mentioned above; △T1≥0; △T2>0. In addition, thawing is generally completed within 24 hours, so the above steps assume that the calculation is performed within a 24-hour cycle, and there are at most two trough periods and peak periods in one cycle; if the set cycle exceeds 24 hours, the actual target thawing time will be reversed from tm. Based on the preservation effect of the food, it is generally not thawed more than 24 hours in advance.

[0138] In addition, it should be noted that the above steps are carried out under the premise that the local area supports the policy of staggered electricity consumption. If the local area does not support the policy of staggered electricity consumption or the user has not activated the staggered electricity consumption function, it is impossible to adjust the thawing time based on the staggered period to save electricity bills, and the above adjustments will not be performed.

[0139] In addition, it should be noted that in the above step S1120, according to the normal thawing speed, it is calculated whether the sum of t and Tj is greater than or equal to tm. If the sum of t and Tj is greater than or equal to tm, it means that the thawing at the normal speed at the current time is not enough to complete the thawing at the planned thawing completion time tm. Therefore, the accelerated thawing method will be adopted. At the same time, the estimated thawing completion time ts is obtained according to the accelerated thawing time, and the user is reminded.

[0140] In addition, it should be noted that in the above steps S1160 to S1180, if there is no off-peak period in the time period of [(tm-Tj-△T1), tm], this means that this period is full of peak periods, and since △T1>0; the length of this period is sufficient for complete thawing, then the deceleration thawing can be performed at the tm-Tj-△T1 time point, thereby reducing the overall thawing power consumption during periods with high electricity prices; wherein, the △T1 value is determined based on laboratory performance tests; if based on comprehensive considerations based on other factors, the deceleration thawing here can also be replaced by the normal thawing speed.

[0141] In addition, it should be noted that in the above step S1150, if there is a low period in the time period of [(tm-Tj-△T1), tm], then accelerated thawing can be performed at the time point tm-Tj+△T2, thereby reducing the overall thawing time during the period of low electricity prices; wherein, the △T3 value is determined based on laboratory performance tests.

[0142] In addition, it should be noted that the above-mentioned thawing speed can be divided into three thawing speeds: normal thawing, accelerated thawing, and decelerated thawing. This can be formulated according to the thawing conditions of different equipment. For example, if the thawing method of the thawing area of ​​the equipment is heating, the accelerated thawing method can generally be to increase the heating power by a certain amount without affecting the freshness of the food; on the contrary, the decelerated thawing method can generally be to reduce the heating power by a certain amount.

[0143] In addition, it should be noted that for the above-mentioned thawing speeds, it is also possible to have more than 3 or 1 or 2 thawing speeds at the same time; if only 1 or 2 thawing speeds are supported, the unsupported thawing speeds in the corresponding steps can be replaced with normal thawing speeds, and the overall thawing time is also a fixed value under the same object and target time; if more thawing speeds are supported, the values ​​in the steps can be further refined and differentiated.

[0144] In addition, it should be noted that with the user's authorization, the above steps can be intelligently calculated and automatically completed and reminded; if the user has not authorized the activation of this intelligent thawing method, it will not be performed automatically, and an active reminder can be given when the user sets the thawing. Further, a comparison chart of energy consumption and electricity costs of intelligent thawing and ordinary thawing can be given to guide users to turn on this function to save more electricity costs.

[0145] like Fig.12 As shown, Fig.12 It is an overall flow chart of a food thawing control method provided in another embodiment of the present application, including but not limited to the following steps S1210 to S1290.

[0146] Step S1210, start;

[0147] Step S1220, determine whether t+Tj≥tm is satisfied, if yes, execute step S1230, otherwise execute step S1240;

[0148] Step S1230, perform fast thawing, remind the user of the estimated thawing completion time ts, and execute step S1270;

[0149] Step S1240, determine whether [(tm-Tj), tm] contains the off-peak and off-peak period Td, if so, execute step S1250, otherwise execute step S1260;

[0150] Step S1250, accelerating thawing at the time point tm-Tj+△T2, and executing step S1270;

[0151] Step S1260, perform normal speed defrosting at the time point tm-Tj, and execute step S1270;

[0152] Step S1270: When the thawing zone reaches the target temperature, thawing is stopped and a thawing completion reminder is sent.
