[0023] Before explaining the embodiments of the present application in detail, some terms involved in the embodiments of the present application will be explained.

[0024] Among them, in the description of the embodiments of the present application, terms such as "first" and "second" can be used in this article to describe various concepts, but unless otherwise specified, these concepts are not limited by these terms. These terms are only used to distinguish one concept from another. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0025] The embodiments of the present application provide a method, an apparatus, an electronic device, and a computer-readable storage medium for controlling food storage in a refrigerator. Specifically, the method for controlling food storage in a refrigerator according to the embodiments of the present application can be executed by an electronic device, where the electronic device can be a device such as a terminal or a server. The terminal can be a refrigerator, a smart phone, a tablet computer, a laptop computer, a touch screen, a game console, a personal computer (PC), a personal digital assistant (PDA), etc. The terminal can also include a client, which can be a game application client, a browser client with a game program, or an instant messaging client, etc. The server can be an independent physical server, or a server cluster or a distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery network (CDN), and big data and artificial intelligence platforms.

[0026] In this embodiment, the above terminal can be a refrigerator, and the food to be stored can be the food in the refrigerator compartment, such as the food in the freezer compartment. If there are at least two drawers in the above refrigerator compartment, then the food to be stored can be in the drawer.

[0027] For example, taking the terminal as an example of the electronic device, when the target drawer in the above at least one drawer stores the target food to be frozen, the terminal can refrigerate the above target drawer at a first preset temperature, and control the above magnetic field module to generate a magnetic field in the above target drawer at a first preset magnetic field intensity to freeze the above target food in the above target drawer; when the freezing condition of the above target food meets the preset freezing completion condition, control the above magnetic field module to turn off the magnetic field in the above target drawer, and refrigerate the above target drawer at a second preset temperature to store the frozen above target food in the above target drawer, where the above second preset temperature is greater than the above first preset temperature; when the refrigeration condition of the above target drawer meets the preset defrosting start condition, control the above magnetic field module to repeatedly alternate between a second preset magnetic field intensity and a third preset magnetic field intensity to cyclically generate a corresponding magnetic field in the above target drawer to defrost the above target drawer until the defrosting condition of the above target drawer meets the preset defrosting end condition, control the above magnetic field module to turn off the magnetic field in the above target drawer, where the above second preset magnetic field intensity is greater than the above first preset magnetic field intensity, and the above first preset magnetic field intensity is greater than the above third preset magnetic field intensity.

[0028] Based on the above problems, the embodiments of the present application provide a food storage control method, device, electronic device, and computer-readable storage medium in a refrigerator, which can promote the preservation of high-quality food during storage in the refrigerator.

[0029] The following will be described in detail with reference to the accompanying drawings. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments. Although the logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order from that shown in the drawings.

[0030] In this embodiment, taking the terminal as an example, this embodiment provides a food storage control method in a refrigerator. A refrigerator compartment is provided, and at least one drawer is provided in the refrigerator compartment. A magnetic field module for generating a magnetic field is provided outside the drawer, such as Figure 1 As shown, the specific process of the food storage control method in this refrigerator can be as follows:

[0031] 101. When the target drawer in the at least one drawer stores the target food to be frozen, cool the target drawer at a first preset temperature, and control the magnetic field module to generate a magnetic field in the target drawer at a first preset magnetic field intensity to freeze the target food in the target drawer.

[0032] Among them, the target food is the food stored in the target drawer and needs to be frozen. The target food can be any food that can be frozen, such as meat, fruits, steamed buns, vegetables, etc.

[0033] In this embodiment, the terminal can respond to the freezing event of the target drawer in at least one drawer in the refrigerator compartment, identify that the target drawer stores the target food to be frozen, and the target food in the target drawer needs to be frozen. For this, the terminal not only controls the refrigeration module to cool the target drawer at a first preset temperature to freeze the target food, but also further controls the magnetic field module to generate a magnetic field at a first preset magnetic field intensity to act on the target food currently being frozen in the target drawer to ensure the quality of the target food during freezing.

[0034] Such as Figure 2 As shown, Figure 2 As shown is the temperature change curve during the storage process of food in the drawer of the refrigerator compartment in this embodiment, Figure 2 where the horizontal axis is time and the vertical axis is temperature. It can be understood that when reducing the temperature of the food from room temperature to Figure 2During the process of the temperature at point A, if the temperature applied to the target drawer is too low, cracking will occur, resulting in cracks on the surface of the food. If the temperature applied to the target drawer is relatively high, the time of the ice crystal zone plateau will be too long. A long ice crystal zone time will cause large ice crystals to form in the target food, damaging the food tissue cells.

[0035] Among them, the cracking phenomenon refers to that during the rapid freezing and cooling process of food, the moisture on the outer surface freezes first, and the ice layer gradually extends inward. When the internal moisture freezes and expands in volume, it will be blocked by the outer ice layer, generating a freezing expansion pressure. When the outer layer cannot withstand the freezing expansion pressure, it will crack, becoming a crack.

[0036] In this regard, in this embodiment, the terminal uses a relatively gentle first preset temperature to refrigerate the target drawer, so that the temperature of the target food is reduced from room temperature to Figure 2 the temperature at point A in it. The first preset temperature can be set according to requirements and food types, and is not limited here. For example, the first preset temperature is set to -30 ± 1°C.

[0037] Moreover, while maintaining the refrigeration of the target drawer at the first preset temperature, the terminal further controls the magnetic field module to generate a magnetic field at the first preset magnetic field intensity. By applying this magnetic field, the supercooling temperature of the food is reduced, that is, Figure 2 the temperature at point B in it is reduced, which shortens the phase change time and process of the ice crystal zone. Generally, compared with the ice crystal zone phase change time without a magnetic field, it can be shortened by about 50%. The ice crystals formed in the target food are more inclined to be atomized and granulated, so that the damage to the cells of the target food is small, and the damage to the cells of the food caused by the large blade-shaped or block-shaped ice crystals without a magnetic field is avoided. Among them, the first preset magnetic field intensity can be set according to requirements and food types, and is not limited here. For example, the first preset magnetic field intensity is set to an intensity value between 5 - 10 mT.

[0038] Among them, the above freezing event is used to indicate that the target food needs to be frozen currently. The above freezing event can be an event generated by a freezing instruction issued by the upper computer. For example, the user connects the mobile terminal held by him / her to the terminal, such as a communication connection, so as to issue a freezing instruction to the terminal; the above freezing event can also be an event generated after detecting that the target food is stored in the refrigerator compartment for a real-time or preset duration; the above freezing event can also be an event generated by a freezing instruction issued by the user by operating the control panel on the terminal, which can be specifically set according to requirements and is not limited here.

[0039] Specifically, a gear adjustment control can be set on the control panel of the terminal to send a freezing instruction by adjusting the gear adjustment control to the freezing gear. In addition, a freezing setting control can be set on the control panel. The freezing setting control can be used to set the freezing temperature and the freezing duration. The freezing duration is used to indicate the time for freezing the target food. After this time, the temperature can be raised to store the frozen target food in an environment with a temperature higher than the freezing temperature, avoiding damage to the target food caused by long-term low temperature. Or, the freezing setting control is used to set the food type of the target food and the food weight of the target food, so that the terminal can determine the freezing temperature and the freezing duration of the target food based on the food type and the food weight of the target food.

[0040] In some embodiments, a freezing duration threshold can be preset, so that when the terminal cools the above-mentioned target drawer at a first preset temperature, the cooling duration is monitored to determine whether the freezing of the target food is completed.

[0041] Specifically, the terminal can obtain the first duration of cooling the target drawer at the first preset temperature and generating a magnetic field in the target drawer at the first preset magnetic field intensity. Then, the first duration is judged to clarify whether the freezing of the target food is completed. If the first duration meets the preset freezing duration threshold, it is determined that the freezing condition of the target food meets the preset freezing completion condition and subsequent operations are required. If the first duration does not meet the preset freezing duration threshold, it is determined that the freezing condition of the target food does not meet the preset freezing completion condition, and the target drawer needs to be continuously cooled at the first preset temperature and a magnetic field needs to be generated in the target drawer at the first preset magnetic field intensity. Among them, the above-mentioned freezing duration threshold can be set according to requirements and food types and is not limited here. For example, the freezing duration threshold is set to 9h.

[0042] 102. When the freezing condition of the above-mentioned target food meets the preset freezing completion condition, control the magnetic field module to turn off the magnetic field in the above-mentioned target drawer and cool the above-mentioned target drawer at a second preset temperature to store the frozen above-mentioned target food in the above-mentioned target drawer, where the second preset temperature is greater than the first preset temperature.

[0043] In this embodiment, when the terminal determines that the freezing condition of the above-mentioned target food meets the preset freezing completion condition, it is clear that the current target food has been frozen, such as Figure 2The target food in [description] goes through the process from point A to point B, C, D, and then to point E. To prevent the target food from being refrigerated at a relatively low temperature for a long time, which may cause the quality of the target food to decline due to freeze recrystallization, such as protein denaturation, increased juice loss, dry and white surface of meat ingredients, and fat oxidation of meat ingredients, the terminal can control the above magnetic field module to turn off the magnetic field in the above target drawer and refrigerate the above target drawer at a temperature higher than the first preset temperature, that is, the second preset temperature, so as to store the frozen target food in the above target drawer, causing the temperature of the target food to be maintained within a certain range after point E in [description]. Figure 2 After point E in [description], the temperature is maintained within a certain range.

[0044] In some embodiments, when the target food is frozen for a long time, due to the moisture of the target food itself and the sealing structure of the target drawer, frosting may occur on the target food or in the target drawer. Therefore, in order to prevent the frost in the target drawer or on the target food from affecting the quality of the target food during storage, in this embodiment, it is necessary to judge whether there is frost in the target drawer where the target food is located, so as to defrost the target drawer in time and avoid affecting the quality of the target food during storage.

[0045] Specifically, the terminal can obtain the second duration of refrigerating the target drawer at the second preset temperature, and then judge this second duration to clarify whether there is frost in the target drawer. If the second duration meets the preset frosting duration threshold, it is determined that the refrigeration condition of the target drawer meets the preset defrosting start condition, and subsequent defrosting operations are required. However, if the second duration does not meet the preset frosting duration threshold, it is determined that the refrigeration condition of the target drawer does not meet the preset defrosting start condition, and the target drawer needs to continue to be refrigerated at the second preset temperature to store the frozen target food in the above target drawer. Among them, the above frosting duration threshold can be set according to requirements and food types, and no limitation is made here. For example, the frosting duration threshold is set to 12h.

[0046] Specifically, a camera can be set in the above drawer. Then, the terminal can take a photo of the above target drawer through the above camera in the target drawer to obtain the drawer environment photo of the above target drawer, and then judge this drawer environment photo to clarify whether there is frost in the target drawer. If there is frost in the above drawer environment photo, it is determined that the refrigeration condition of the above target drawer meets the preset defrosting start condition, and subsequent defrosting operations are required. However, if there is no frost in the above drawer environment photo, it is determined that the refrigeration condition of the above target drawer does not meet the preset defrosting start condition, and the target drawer needs to continue to be refrigerated at the second preset temperature to store the frozen target food in the above target drawer.

[0047] In addition, since less frost in the target drawer has less impact on the target food, the terminal can further set a frost percentage rule for whether there is frost in the target drawer, so as to avoid losses caused by defrosting when the amount of frost in the target drawer is small. For example, if the percentage of frost in the target drawer is greater than the preset frost percentage threshold, it is determined that the refrigeration condition of the above-mentioned target drawer meets the preset defrost start condition, and subsequent defrosting operations need to be performed.

[0048] Among them, the above camera can take pictures of the environment in the drawer every preset shooting duration, or can take pictures of the environment in the above drawer in real time. And, there can be at least one of the above cameras, and at least one camera can be evenly arranged at various positions in the drawer, and the above camera can rotate 360° to take pictures.

[0049] 103. When the refrigeration condition of the above target drawer meets the preset defrost start condition, control the magnetic field module to repeatedly alternate between a second preset magnetic field intensity and a third preset magnetic field intensity to cyclically generate a corresponding magnetic field in the above target drawer, so as to defrost the above target drawer until the defrosting condition of the above target drawer meets the preset defrost end condition, control the magnetic field module to turn off the magnetic field in the above target drawer, where the second preset magnetic field intensity is greater than the first preset magnetic field intensity, and the first preset magnetic field intensity is greater than the third preset magnetic field intensity.

[0050] In this embodiment, when the terminal determines that the refrigeration condition of the above target drawer meets the preset defrost start condition, it is clear that frost has appeared in the current target drawer, and the frost can appear on the target food or on the side wall of the target drawer. In this regard, the terminal can use a method of alternating a magnetic field with a high magnetic field intensity and a magnetic field with a low magnetic field intensity to defrost the target drawer, so as to remove the frost in the target drawer and maintain the quality of the target food in the target drawer.

[0051] It can be understood that the terminal can use a magnetic field with a second preset magnetic field intensity greater than the first preset magnetic field intensity to defrost the target drawer. Under the action of the magnetic field with a high magnetic field intensity of the second preset magnetic field intensity, the temperature in the target drawer will rise, so that the frost will turn into water and evaporate in the sealed drawer in time, maintaining a high-humidity environment for the target food and preventing the target food from drying out.

[0052] Under high magnetic field strength, the temperature of the components in the magnetic field module that generates the magnetic field will increase. If there is an electromagnetic coil in the magnetic field module, the temperature of the electromagnetic coil will increase. To prevent the temperature of the components in the magnetic field module from being too high and affecting the temperature in the refrigerator compartment, after the terminal turns on the magnetic field with the second preset magnetic field strength for a certain duration, it needs to switch to turn on the magnetic field with the third preset magnetic field strength that is less than the first preset magnetic field strength for a certain duration, so as to avoid the situation where the temperature of the components in the magnetic field module is too high with a low magnetic field strength. Thus, by alternating the magnetic field with high magnetic field strength and low magnetic field strength, defrosting is performed on the target drawer to remove the frost in the target drawer and maintain the quality of the target food in the target drawer.

[0053] Among them, the second preset magnetic field strength and the third preset magnetic field strength can be set according to requirements and food types, etc., and are not limited here. For example, the second preset magnetic field strength can be set to any intensity value within 10 - 15 mT, and the third preset magnetic field strength can be set to any intensity value within 1.8 mT - 5 mT. When the magnetic fields alternate, the duration of the magnetic field corresponding to the second preset magnetic field strength and the duration of the magnetic field corresponding to the third preset magnetic field strength can also be different according to requirements and the different settings of the components in the magnetic field module, and are not limited here.

[0054] In some embodiments, the above magnetic field module includes a plurality of first electromagnetic coils, and the plurality of first electromagnetic coils are evenly arranged outside the above drawer. Controlling the magnetic field module to repeatedly alternate between the second preset magnetic field strength and the third preset magnetic field strength to cyclically generate corresponding magnetic fields in the above target drawer may include: The terminal can determine the target electromagnetic coil corresponding to the local area with frost in the above target drawer from the above plurality of first electromagnetic coils based on the above drawer environment photo, that is, the terminal needs to control the target electromagnetic coil to defrost the local area with frost, that is, control the target electromagnetic coil to generate a first magnetic field in the above target drawer with the second preset magnetic field strength, and determine the first duration of the first magnetic field, so as to judge whether the duration of the first magnetic field reaches the critical duration based on the first duration.

[0055] If the above first duration meets the preset first duration threshold, in order to prevent the temperature of the components in the magnetic field module from being too high, then control the target electromagnetic coil to generate a second magnetic field in the above target drawer with the third preset magnetic field strength, and determine the second duration of the second magnetic field, so as to judge whether the duration of the second magnetic field reaches the critical duration based on the second duration. In addition, if the above first duration does not meet the preset first duration threshold, then continue to control the target electromagnetic coil to generate a first magnetic field in the above target drawer with the second preset magnetic field strength.

[0056] If the above-mentioned second duration meets the preset second duration threshold, it indicates that the components in the current magnetic field module are at an appropriate temperature. Then, return to execute the step of taking a photo of the target drawer through the above-mentioned camera to determine whether there is still frost. Among them, the above-mentioned first duration threshold is less than the above-mentioned second duration threshold, and the above-mentioned first duration threshold and the second duration threshold can be set according to requirements and food types, etc., and are not limited here. For example, set the first duration threshold to 1h and the second duration threshold to 2h.

[0057] Specifically, as Figure 3 shown, Figure 3 shown is the drawer in the refrigerator compartment. In Figure 3 it can be seen that the drawer in the refrigerator compartment is a sealed structure, and two first electromagnetic coils are sequentially installed on each surface of the drawer, and the arrangement of the first electromagnetic coils on the 8 surfaces of the drawer is the same, and each first electromagnetic coil can be independently controlled for power supply.

[0058] In some embodiments, after returning to execute the step of taking a photo of the target drawer through the above-mentioned camera, it may further include: If the refrigeration condition of the above-mentioned target drawer meets the preset defrosting start condition, then when controlling the above-mentioned target electromagnetic coil to generate a first magnetic field in the above-mentioned target drawer with a second preset magnetic field intensity, periodically obtain the latest drawer environment photo of the above-mentioned target drawer, and judge the obtained latest drawer environment photo to determine whether there is still frost in the local area to which the above-mentioned target electromagnetic coil belongs in the above-mentioned latest drawer environment photo. If there is no frost in the local area to which the above-mentioned target electromagnetic coil belongs in the above-mentioned latest drawer environment photo, control the above-mentioned target electromagnetic coil to turn off the first magnetic field in the above-mentioned target drawer, and there is no need to defrost anymore. However, if there is frost in the local area to which the above-mentioned target electromagnetic coil belongs in the above-mentioned latest drawer environment photo, continue to control the above-mentioned target electromagnetic coil to generate a first magnetic field in the above-mentioned target drawer. It can be understood that when controlling the above-mentioned target electromagnetic coil to generate a second magnetic field in the above-mentioned target drawer with a third preset magnetic field intensity, it is necessary to judge the photo when the second duration of the above-mentioned second magnetic field meets the preset second duration threshold.

[0059] In some embodiments, if the determination of whether the refrigeration condition of the target drawer meets the preset defrost start condition is made by comparing the proportion of ice frost in the target drawer with the preset ice frost proportion threshold, then during the first defrost, the terminal can control multiple first electromagnetic coils to generate a first magnetic field in the target drawer at a second preset magnetic field intensity, and determine a first duration of the first magnetic field. If the first duration meets the preset first duration threshold, then control the multiple first electromagnetic coils to generate a second magnetic field in the target drawer at a third preset magnetic field intensity, and determine a second duration of the second magnetic field. If the second duration meets the preset second duration threshold, then return to execute the step of taking a photo of the target drawer by the camera, and when it is determined for the second time that there is ice frost in the drawer environment photo, that is, when it is determined that the refrigeration condition of the target drawer meets the preset defrost start condition, use the method of determining the target electromagnetic coil corresponding to the local area with ice frost in the target drawer from the multiple first electromagnetic coils based on the drawer environment photo to defrost the local area in the target drawer.

[0060] In some embodiments, the magnetic field module includes a second electromagnetic coil wound outside the drawer. Controlling the magnetic field module to repeatedly and alternately generate corresponding magnetic fields in the target drawer between a second preset magnetic field intensity and a third preset magnetic field intensity may include: the terminal can control the second electromagnetic coil to generate a second magnetic field in the target drawer at a third preset magnetic field intensity, and determine a third duration of the second magnetic field to judge whether the duration of the second magnetic field reaches a critical duration based on the third duration.

[0061] If the third duration meets the preset third duration threshold, it indicates that the components in the current magnetic field module are at an appropriate temperature, then control the second electromagnetic coil to generate a first magnetic field in the target drawer at a second preset magnetic field intensity, and determine a fourth duration of the first magnetic field to judge whether the duration of the first magnetic field reaches a critical duration based on the fourth duration. In addition, if the third duration does not meet the preset third duration threshold, then continue to control the target electromagnetic coil to generate a second magnetic field in the target drawer at a third preset magnetic field intensity.

[0062] If the above-mentioned fourth duration meets the preset fourth duration threshold, in order to prevent the temperature of the components in the magnetic field module from being too high, the step of controlling the second electromagnetic coil to generate a second magnetic field in the target drawer at a third preset magnetic field strength is returned. Among them, the third duration threshold is greater than the fourth duration threshold, and the third duration threshold and the fourth duration threshold can be set according to requirements and food types, etc., and are not limited here. For example, the third duration threshold is set to 6h, and the fourth duration threshold is set to 2h.

[0063] It can be understood that in the scenario corresponding to the second electromagnetic coil, the terminal can only judge whether the refrigeration condition of the target drawer meets the preset defrosting start condition based on the defrosting duration threshold. Therefore, in order to prevent the first magnetic field from being directly applied with the second preset magnetic field strength of high magnetic field strength, resulting in abnormal situations, the terminal needs to first apply the second magnetic field with the third preset magnetic field strength of low magnetic field strength, and then perform the magnetic field alternation of high magnetic field strength.

[0064] In some embodiments, in the scenario corresponding to the second electromagnetic coil, the terminal can determine the magnetic field accumulation duration of generating the first magnetic field in the target drawer at the second preset magnetic field strength, and judge the magnetic field accumulation duration to clarify whether the defrosting condition of the target drawer meets the preset defrosting end condition. If the magnetic field accumulation duration meets the preset defrosting duration threshold, it is determined that the defrosting condition of the target drawer meets the preset defrosting end condition. If the magnetic field accumulation duration does not meet the preset defrosting duration threshold, it is determined that the defrosting condition of the target drawer does not meet the preset defrosting end condition. Among them, the defrosting duration threshold can be set according to requirements and food types, etc., and is not limited here. For example, the defrosting duration threshold is set to 3h.

[0065] Exemplarily, as Figure 4 shown, Figure 4 shown is the drawer in the refrigerator compartment. In Figure 4 it can be seen that the drawer in the refrigerator compartment is a sealed structure, and the second electromagnetic coil is wound around the drawer. This winding method can be left-right winding or up-down winding, and can be specifically set according to requirements.

[0066] In some embodiments, when a thawing instruction for the target food is received, the target drawer is refrigerated at a third preset temperature, and the magnetic field module is controlled to generate a magnetic field in the target drawer at a fourth preset magnetic field strength to thaw the target food in the target drawer. It can be understood that at this temperature, the food ingredients will remain slightly frozen and there will be no juice loss. Under the action of the magnetic field, the growth of microorganisms can be reduced at the same time, and the color protection of the food ingredients can be achieved.

[0067] Among them, the above third preset temperature is greater than the above second preset range, and the above fourth preset magnetic field intensity is greater than the above first preset magnetic field intensity.

[0068] Specifically, the above third preset temperature can be set according to information such as requirements or food types, which is not limited here. For example, the third preset temperature is set to -2.5±1°C; the above fourth preset magnetic field intensity can be set according to information such as requirements or food types, which is not limited here. For example, the fourth preset magnetic field intensity is set to any intensity value in 10-15 mT.

[0069] Specifically, the above thawing instruction can be a thawing instruction issued by the host computer. For example, the user interconnects with the terminal through the mobile terminal held by him, such as a communication connection, so as to issue a thawing instruction to the terminal; the thawing instruction is a thawing instruction issued by the user by operating the control panel on the terminal.

[0070] Specifically, a gear adjustment control can be set on the control panel of the terminal to issue a thawing instruction by adjusting the gear adjustment control to the thawing gear. In addition, a thawing setting control can also be set on the control panel. The thawing setting control can be used to set the thawing temperature and the thawing duration. The thawing duration is used to indicate the time for thawing the target food. After this time, a prompt operation can be performed to take out the thawed target food from the refrigerator. Or, the thawing setting control is used to set the food type and food weight of the target food, so that the terminal can determine the thawing temperature and thawing duration of the target food based on the food type and food weight of the target food.

[0071] In some embodiments, the method of forming an ice coat for the target food can be used to prevent dry weight loss and prevent the occurrence of freezer burn, that is, when the defrosting condition of the above target drawer meets the preset defrosting end condition, at this time, the water on the surface of the target food has not completely evaporated, and the above target drawer is refrigerated at the fourth preset temperature, that is, by rapidly cooling, so that the above target food in the above target drawer forms an ice coat at a low temperature. Among them, the above fourth preset temperature is less than the above first preset temperature, and the above fourth preset temperature can be set according to information such as requirements or food types, which is not limited here. For example, the fourth preset temperature is set to -40±1°C.

[0072] As can be seen from the above, by providing a refrigerator compartment with at least one drawer provided therein, a magnetic field module for generating a magnetic field is provided outside the drawer. And when the target drawer among the at least one drawer stores target food to be frozen, the target drawer is refrigerated at a first preset temperature, and the magnetic field module is controlled to generate a magnetic field in the target drawer at a first preset magnetic field intensity to freeze the target food in the target drawer, so as to reduce the supercooling temperature of the food by applying a magnetic field, cause the ice crystals formed around the food to atomize at a low temperature, and reduce the damage to food cells. Then, when the freezing condition of the target food meets the preset freezing completion condition, the magnetic field module is controlled to turn off the magnetic field in the target drawer, and the target drawer is refrigerated at a second preset temperature to store the frozen target food in the target drawer, where the second preset temperature is greater than the first preset temperature. Finally, when the refrigeration condition of the target drawer meets the preset defrosting start condition, the magnetic field module is controlled to cyclically generate corresponding magnetic fields in the target drawer in a manner of repeating and alternating between a second preset magnetic field intensity and a third preset magnetic field intensity, so that the target drawer is defrosted. Until the defrosting condition of the target drawer meets the preset defrosting end condition, the magnetic field module is controlled to turn off the magnetic field in the target drawer, thereby defrosting the target drawer through the magnetic field with a higher second preset magnetic field intensity, and evaporating the water generated after defrosting through the magnetic field with a lower third preset magnetic field intensity, keeping the food in a high-humidity environment, avoiding the problem of dry loss of the food, and further promoting the food to maintain a high quality during the storage process in the refrigerator as a whole.

[0073] To better implement the above method, an embodiment of the present application further provides a food storage control device in a refrigerator. The food storage control device in the refrigerator can be specifically integrated in an electronic device, such as a computer device, and the computer device can be a device such as a terminal or a server.

[0097] In some embodiments, the food storage control device in the above refrigerator further includes a thawing module, and the thawing module is specifically configured to:

[0098] When a thawing instruction for the above target food is received, refrigerate the above target drawer at a third preset temperature, and control the above magnetic field module to generate a magnetic field in the above target drawer at a fourth preset magnetic field intensity to thaw the above target food in the above target drawer, where the above third preset temperature is greater than the above second preset range, and the above fourth preset magnetic field intensity is greater than the above first preset magnetic field intensity.
