The refrigeration device 30 is disposed in the accommodating space 11 , and the refrigeration device 30 is used to cool the storage compartment 21 . The electromagnetic device 40 is disposed on the side of the bottom plate 22 away from the storage compartment 21 . The control board 50 is electrically connected to the refrigeration device 30 and the electromagnetic device 40, respectively. The control board 50 is used to control the refrigeration temperature of the refrigeration device 30 and the magnetic field strength of the electromagnetic device 40, so that the storage compartment 21 has different characteristics in different working modes. temperature and magnetic field strength. The working modes of the storage compartment 21 include a short-term eating mode, a preserved eating mode and a defrosting mode. Three working modes are set for the storage compartment 21 in the refrigerator 1, and different refrigeration temperatures of the refrigerating device 30 and magnetic field strength of the electromagnetic device 40 are set for different working modes, so that the same storage compartment 21 can both realize the protection of food materials.

The connecting pieces such as screws are inserted into the mounting holes of the mounting shell 41 and the mounting holes of the base plate 22 respectively to realize the connection between the mounting shell 41 and the bottom plate 22, and the installation is realized by pulling the connecting pieces out of the mounting holes of the base plate 22 and the mounting holes of the mounting shell 41.

The material of the coil 42 may be a copper wire material, or an aluminum wire material and other materials that can generate a magnetic field. The cover body 43 is connected with the mounting shell 41 , and covers the coil 42 . That is, the mounting case 41 and the cover body 43 encapsulate the coil 42 in an accommodating space.

Exemplarily, the refrigerator 1 may further include a heat-conducting plate 60 disposed between the electromagnetic device 40 and the bottom plate 22 . The heat-conducting plate 60 is used for: converting electrical energy into heat energy through the electromagnetic device 40 , and causing the heat-conducting plate 60 to generate an induced eddy current to heat and thaw the food in the storage compartment 21 . That is to say, the heat conducting plate 60 is used to transfer the electromagnetically generated heat into the storage compartment 21 to defrost the food in the storage compartment 21 . The heat-conducting plate 60 can be a metal plate with high heat-conducting efficiency, so that the heat-conducting plate 60 can quickly transfer the electromagnetically generated heat to the food that needs to be thawed. For example, a material with high thermal conductivity, such as graphene, may also be added to the thermally conductive plate 60 . In some embodiments, the thermally conductive plate 60 may be integrally formed with the bottom plate 22 , that is, the material of the bottom plate 22 is made of a metal thermally conductive material.

The control board 50 can be understood as the main control board of the refrigerator 1. The control board 50 is electrically connected to the refrigeration device 30 and the electromagnetic device 40, respectively. The control board 50 is used to control the refrigeration temperature of the refrigeration device 30 and the magnetic field strength of the electromagnetic device 40, so that the The storage compartment 21 has different temperatures and magnetic field strengths in different working modes. The working modes of the storage compartment 21 may include a short-term eating mode, a preserved eating mode, and a defrosting mode.

The short-term eating mode refers to a working mode in which the ingredients are consumed within 3 to 5 days. At this time, the temperature of the storage compartment 21 can be controlled within the range of -1°C to 0°C, that is, the control panel 50 controls the cooling of the refrigerating device 30 The temperature is in the range of -1° C. to 0° C., so that the food material, such as meat material, will be in a non-frozen or slightly frozen state when placed in the storage compartment 21 for 3 to 5 days. The control board 50 controls the magnetic field strength of the electromagnetic device 40 to be within the range of 2hmt-6hmt, to ensure that the food is in a fresh state.

The preservation and consumption mode refers to the working mode in which the ingredients cannot be eaten in a short period of time and need to be preserved and eaten for a long time. Short-term and long-term are relative terms. For example, short-term time can be understood as 0 to 5 days, and long-term time can be understood as 6 days to one month, or even three months. In the preservation and eating mode, the temperature of the storage compartment 21 can be divided into a first gear, a second gear and a third gear, the temperature of the first gear is lower than the temperature of the second gear, and the temperature of the second gear temperature below the third gear. That is to say, the first gear, the second gear and the third gear can be understood as three gears: strong, medium and weak. For example, the temperature corresponding to the first gear can be -18°C to -10°C The temperature corresponding to the second gear may be in the range of -10°C to -5°C, and the temperature corresponding to the third gear may be in the range of -5°C to -1°C. For the temperature selection of the storage compartment 21, the user's selected operation can be obtained, that is, the user can select the temperature of the storage compartment 21 as required, and then the control board 50 cools the refrigeration device 30 according to the received control command. temperature control. Of course, if the user does not select a gear within the first time period, the control panel 50 is directly caused to send a control command to the refrigeration device 30 to select the cooling temperature of the refrigeration device 30 as the second gear. At this time, the control board 50 can control the magnetic field strength of the electromagnetic device 40 to be in the range of 0hmt to 2hmt. Since the temperature of the compartment is low, the magnetic field strength in this case can be relatively small. Since the temperature of the storage compartment 21 is very low and the magnetic field acts, the meat ingredients will be kept fresh for a long time. But at this time, because the ingredients are frozen, the ingredients are hard and difficult to cut.

The defrosting mode is a working mode for defrosting the ingredients. In order to facilitate the user's operation, the user can directly thaw the ingredients in the preserved edible mode without taking out the ingredients for thawing, which facilitates the process of thawing the ingredients and makes the refrigerator 1 more intelligent. . When the storage compartment 21 is in the defrosting mode, the control panel 50 controls the cooling temperature of the refrigerating device 30 to be a temperature within a temperature range, such as -5°C to -2°C. The control board 50 controls the magnetic field strength of the electromagnetic device 40 to be a magnetic field strength within a range of magnetic field strength, such that the magnetic field strength at this time can be 5-6 times the magnetic field strength in the preservation and eating mode, for example, the magnetic field strength in the defrosting mode can be 10hmt to 15hmt range. The main function of the electromagnetic device 40 in the defrosting mode is to generate heat to heat the food in the storage compartment 21 . Moreover, maintaining the temperature in the storage compartment 21 at -5°C to -2°C at this time can facilitate the segmentation of the meat ingredients, and can ensure that the meat juice is not lost, so as to achieve the effect of thawing and keeping the meat fresh.

Exemplarily, for the control of the magnetic field strength of the electromagnetic device 40 , the magnetic field strength of the electromagnetic device 40 can be changed by adjusting the on-off ratio of the magnetic field, adjusting the current value flowing through the coil 42 or changing the number of turns of the energized coil 42 .

It should be noted that the storage compartment 21 may be referred to as a freezing compartment or a temperature-changing compartment, and the storage compartment 21 has various working modes, which can not only achieve preservation and freshness of the ingredients, but also realize the thawing of the ingredients, without the need for Defrost the frozen food after taking it out. When thawing is required, simply pressing the operation button, or remotely controlling the refrigerator 1 to select the thawing mode, can realize the thawing of the ingredients, which is convenient for the user to operate, and further improves the user experience.

In order to more clearly describe the method for storing and thawing food materials according to the embodiments of the present application, the following description will be made from the perspective of the control method of the refrigerator.

Exemplarily, please refer to FIG. 3 in conjunction with FIG. 1 and FIG. 2 , and FIG. 3 is a first schematic flowchart of a control method for a refrigerator provided by an embodiment of the present application.

102. Control the refrigeration temperature of the refrigeration device and the magnetic field strength of the electromagnetic device according to the working mode of the storage compartment.

Regarding steps 101 and 102:

Three working modes are set for the storage compartment 21, that is, the working modes include a short-term eating mode, a preserved eating mode and a defrosting mode. Different refrigeration temperatures and magnetic field strengths are given to the storage compartment 21 for each working mode, so as to meet different storage requirements for food items in different working modes. The cooling temperature of the refrigerating device 30 and the magnetic field strength of the electromagnetic device 40 are controlled according to the working mode of the storage compartment 21 .

Exemplarily, please refer to FIG. 4 in conjunction with FIG. 1 to FIG. 3 . FIG. 4 is a second schematic flowchart of the control method for a refrigerator provided by an embodiment of the present application. Embodiments of the present application also provide a method for controlling a refrigerator, which may include:

201. Acquire a working mode of the storage compartment, where the working mode includes a short-term eating mode, a preserved eating mode, and a thawing mode.

For step 201, reference may be made to the description of step 101, which will not be repeated here.

202. If the working mode of the storage compartment is the short-term eating mode, control the refrigeration device to adjust the temperature of the storage compartment to the first temperature, and control the magnetic field strength of the electromagnetic device to be the first magnetic field strength, so as to control the food in the storage compartment. Keep refrigerated.

Exemplarily, if the working mode of the storage compartment 21 is the short-term eating mode, the refrigerating device 30 is controlled to adjust the temperature of the storage compartment 21 to the first temperature, and the magnetic field strength of the electromagnetic device 40 is controlled to be the first magnetic field strength, so that The food in the storage compartment 21 is refrigerated and fresh. The short-term eating mode refers to the working mode in which the ingredients are consumed within 3 to 5 days. At this time, the temperature of the storage compartment 21 can be controlled within the range of -1°C to 0°C, that is, the cooling temperature of the refrigeration device 30 is controlled to be within -1°C. In the range of 0°C, the food such as meat will be in a non-frozen or slightly frozen state when placed in the storage compartment 21 for 3 to 5 days. The intensity of the magnetic field of the electromagnetic device 40 is controlled to be in the range of 2hmt-6hmt to ensure that the food is in a fresh state.

203. If the working mode of the storage compartment is the preservation and eating mode, control the refrigeration device to adjust the temperature of the storage compartment to a second temperature, where the second temperature is lower than the first temperature, and control the magnetic field strength of the electromagnetic device to be the second magnetic field The intensity of the second magnetic field is smaller than the intensity of the first magnetic field, so as to freeze and freshen the ingredients in the storage compartment.

If the working mode of the storage compartment 21 is the food preservation mode, the refrigeration device 30 is controlled to adjust the temperature of the storage compartment 21 to a second temperature, which is lower than the first temperature, and the magnetic field strength of the electromagnetic device 40 is controlled to be the first temperature. The second magnetic field strength is smaller than the first magnetic field strength, so as to freeze and freshen the food in the storage compartment 21 . The preservation and consumption mode refers to the working mode in which the ingredients cannot be eaten in a short period of time and need to be preserved and eaten for a long time. Short-term and long-term are relative terms. For example, short-term time can be understood as 0 to 5 days, and long-term time can be understood as 6 days to one month, or even three months. In the saving and eating mode, the user's operation on the temperature gear of the storage compartment 21 can be obtained. The temperature gear includes the first gear, the second gear and the third gear, and the temperature of the first gear is lower than that of the second gear. The temperature of the second gear is lower than the temperature of the third gear. If the user has a selected temperature level within the first time period, the refrigerating device 30 is controlled to cool the storage compartment 21 according to the temperature corresponding to the selected temperature level. If the user does not select a temperature gear within the first time period, the refrigerating device 30 is controlled to cool the storage compartment 21 according to the temperature corresponding to the second gear. For example, the first time period may be 1 minute. In the preservation and eating mode, the temperature of the storage compartment 21 can be divided into a first gear, a second gear and a third gear, and the first gear, the second gear and the third gear can be understood as strong, neutral Weak three gears, for example, the temperature corresponding to the first gear can be a temperature in the range of -18°C to -10°C, and the temperature corresponding to the second gear can be a temperature in the range of -10°C to -5°C. The temperature corresponding to the third gear may be a temperature in the range of -5°C to -1°C. For the temperature selection of the storage compartment 21, the user's selected operation can be obtained, that is, the user can select the temperature of the storage compartment 21 as required, and then control the cooling temperature of the refrigeration device 30. Of course, if the user does not select a gear within the first time period, the control command is directly sent to the refrigeration device 30 to select the cooling temperature of the refrigeration device 30 as the second gear. At this time, the magnetic field strength of the electromagnetic device 40 can be controlled to be in the range of 0hmt to 2hmt. Due to the low temperature of the compartment, the magnetic field strength in this case can be relatively small. Therefore, the second magnetic field strength can be smaller than the first magnetic field strength. Since the temperature of the storage compartment 21 is very low and the magnetic field acts, the meat ingredients will be kept fresh for a long time. But at this time, because the ingredients are frozen, the ingredients are hard and difficult to cut.

204. If the working mode of the storage compartment is the defrosting mode, control the refrigeration device to adjust the temperature of the storage compartment to a third temperature, where the third temperature is greater than the second temperature, and control the magnetic field strength of the electromagnetic device to be the third magnetic field strength, The third magnetic field strength is greater than the second magnetic field strength, so as to thaw the food in the storage compartment.

The defrosting mode is a working mode for defrosting the ingredients. In order to facilitate the user's operation, the user can directly thaw the ingredients in the preserved edible mode without taking out the ingredients for thawing, which facilitates the process of thawing the ingredients and makes the refrigerator 1 more intelligent. . When the storage compartment 21 is in the defrosting mode, the cooling temperature of the refrigeration device 30 is controlled to be a third temperature, and the third temperature may be a temperature within a temperature range, such as -5°C to -2°C. The magnetic field strength of the electromagnetic device 40 is controlled to be a magnetic field strength in a range of magnetic field strengths, such that the magnetic field strength at this time can be 5-6 times the magnetic field strength in the preservation and eating mode, for example, the magnetic field strength in the defrosting mode can be in the range of 10hmt to 15hmt . The main function of the electromagnetic device 40 in the defrosting mode is to generate heat to heat the food in the storage compartment 21 . Moreover, maintaining the temperature in the storage compartment 21 at -5°C to -2°C at this time can facilitate the segmentation of the meat ingredients, and can ensure that the meat juice is not lost, so as to achieve the effect of thawing and keeping the meat fresh.
