Illustratively, the refrigerator 1 may further include a heat conductive plate 60, the heat conductive plate 60 being disposed between the solenoid 40 and the bottom plate 22. The heat conduction plate 60 is used for: the electromagnetic device 40 converts the electric energy into heat energy, and the heat conduction plate 60 generates induced eddy current to heat and thaw the food material in the storage compartment 21. That is, the heat conduction plate 60 serves to transfer electromagnetically generated heat into the storage compartment 21 to thaw food material in the storage compartment 21. The heat conducting plate 60 may be a metal plate with high heat conducting efficiency, so that the heat conducting plate 60 can rapidly transfer the heat generated by the electromagnetism to the food material to be thawed. For example, a material with high heat conduction efficiency, such as graphene, may be added to the heat conduction plate 60. In some embodiments, the heat-conducting plate 60 may be integrally formed with the bottom plate 22, i.e., the material of the bottom plate 22 is made of a metal heat-conducting material.
The control board 50 may be understood as a 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, and the control board 50 is used for controlling 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 temperatures and magnetic field strengths in different operation modes. The operating modes of the storage compartment 21 may include a short-term consumption mode, a preservation consumption mode, and a thawing mode.
The short-term eating mode is a working mode in which the food material is consumed within 3 to 5 days, and the temperature of the storage compartment 21 can be controlled within a range from-1 ℃ to 0 ℃, that is, the control board 50 controls the refrigerating temperature of the refrigerating device 30 within a range from-1 ℃ to 0 ℃, so that the food material, such as meat food material, is placed in the storage compartment 21 for 3 to 5 days and is in an unfrozen or slightly frozen state. The control panel 50 controls the magnetic field intensity of the electromagnetic device 40 within the range of 2hmt-6hmt, so that the food materials are guaranteed to be in a fresh state.
The preservation and eating mode refers to a working mode that the food materials are not eaten in a short time and need to be preserved and eaten for a long time. Short-term and long-term are relatively general, for example, short-term times are understood to mean from 0 to 5 days, and long-term times are understood to mean from 6 days to one month, or even three months. In the food preservation 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 that of the second gear, and the temperature of the second gear is lower than that of the third gear. That is, the first gear, the second gear, and the third gear may be understood as three gears of strong, medium, and weak, for example, the first gear may correspond to a temperature in a range of-18 ℃ to-10 ℃, the second gear may correspond to a temperature in a range of-10 ℃ to-5 ℃, and the third gear may correspond to a temperature in a range of-5 ℃ to-1 ℃. The selection of the temperature of the storage compartment 21 can be obtained through the user's selection operation, that is, the user can select the temperature of the storage compartment 21 as required, and then the control board 50 controls the cooling temperature of the cooling device 30 according to the received control instruction. Of course, if the user does not select the gear within the first time period, the control board 50 directly sends a control command to the cooling device 30, and the cooling temperature of the cooling device 30 is selected 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, and the magnetic field strength in this case can be relatively small because the temperature of the chamber is low. Due to the low temperature and the magnetic field effect of the storage chamber 21, the meat food can be preserved for a long time. However, the material is frozen, which makes the material harder and more difficult to cut.
The thawing mode is a working mode for thawing food materials, so that a user can directly thaw the food materials in the storage eating mode for convenience of user operation, the food materials are not required to be taken out for thawing, the process of thawing the food materials is facilitated, and the refrigerator 1 is more intelligent. When the storage compartment 21 is in the defrost mode, the control board 50 controls the refrigeration temperature of the refrigeration device 30 to a temperature within a temperature range, such as-5 ℃ to-2 ℃. The control board 50 controls the magnetic field strength of the electromagnetic device 40 to be within a magnetic field strength range, for example, the magnetic field strength in the storage mode may be 5-6 times the magnetic field strength in the food preservation mode, for example, the magnetic field strength in the thawing mode may be 10 hmt-15 hmt. The main function of the electromagnetic device 40 in the thawing mode is to generate heat to heat the food material in the storage compartment 21. And, keep the temperature in the storage compartment 21 at-5 deg.C to-2 deg.C at this moment, can be convenient for cutting apart the meat food material, and can guarantee the juice of the meat does not lose, reach the effect that the meat unfreezes and keeps fresh.
For example, for controlling the magnetic field strength of electromagnetic device 40, the magnetic field strength of electromagnetic device 40 may be changed by adjusting the on/off ratio of the magnetic field, adjusting the value of current flowing through coil 42, or changing the number of turns of 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 multiple working modes, so that not only can food materials be stored and kept fresh, but also food materials can be thawed, and the frozen food materials do not need to be taken out for thawing operation. When needs are unfrozen, only need press the operation button, perhaps the mode of unfreezing is selected to remote control refrigerator 1, can realize the unfreezing to eating the material, convenience of customers operates, and then can promote the user and use experience.
In order to more clearly describe the method for preserving and thawing the food material according to the embodiment of the present application, the following description will be made from the perspective of a control method of a refrigerator.
For example, please refer to fig. 3 in combination with fig. 1 and fig. 2, and fig. 3 is a first flowchart of a control method of a refrigerator according to an embodiment of the present application. The embodiment of the present application further provides a control method of a refrigerator, and the structural composition of the refrigerator 1 may refer to the above description, which is not described herein again. The control method of the refrigerator may include:
101. and acquiring working modes of the storage chamber, wherein the working modes comprise a short-term eating mode, a preservation eating mode and a thawing mode.
102. And controlling the refrigerating temperature of the refrigerating device and the magnetic field intensity of the electromagnetic device according to the working mode of the storage compartment.
With respect to steps 101 and 102:
three operation modes are set for the storage compartment 21, that is, the operation modes include a short-term consumption mode, a preservation consumption mode, and a thawing mode. Different refrigeration temperatures and magnetic field strengths are given to the storage compartment 21 for each working mode, so that different storage requirements on food materials in different working modes are met. The cooling temperature of the cooling device 30 and the magnetic field strength of the electromagnetic device 40 are controlled according to the operation mode of the storage compartment 21.
For example, please refer to fig. 4 in combination with fig. 1 to fig. 3, and fig. 4 is a second flow chart of the control method of the refrigerator according to the embodiment of the present application. The embodiment of the present application further provides a control method of a refrigerator, which may include:
201. and acquiring the working modes of the storage chamber, wherein the working modes comprise a short-term eating mode, a preserving eating mode and a unfreezing mode.
Step 201 may refer to the description of step 101, which is not described herein again.
202. If the working mode of the storage chamber is a short-term eating mode, the refrigerating device is controlled to adjust the temperature of the storage chamber to the first temperature, and the magnetic field intensity of the electromagnetic device is controlled to be the first magnetic field intensity, so that the food materials in the storage chamber can be refrigerated and kept fresh.
For example, if the operation mode of the storage compartment 21 is the short-term consumption mode, the refrigeration 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 the first magnetic field strength, so as to refrigerate and keep fresh the food in the storage compartment 21. The short-term consumption mode refers to a working mode that the food materials are consumed within 3 to 5 days, and the temperature of the storage chamber 21 can be controlled within a range from-1 ℃ to 0 ℃, that is, the refrigeration temperature of the refrigeration device 30 is controlled within a range from-1 ℃ to 0 ℃, so that the food materials, such as meat food materials, can be in an unfrozen or slightly frozen state after being placed in the storage chamber 21 for 3 to 5 days. The magnetic field intensity of the electromagnetic device 40 is controlled within the range of 2hmt-6hmt, so that the food materials are guaranteed to be in a fresh state.
203. If the working mode of the storage chamber is a food preservation mode, the refrigerating device is controlled to adjust the temperature of the storage chamber to a second temperature, the second temperature is lower than the first temperature, the magnetic field intensity of the electromagnetic device is controlled to be a second magnetic field intensity, and the second magnetic field intensity is smaller than the first magnetic field intensity, so that the food materials in the storage chamber can be frozen and preserved.
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, the second temperature is lower than the first temperature, the magnetic field strength of the electromagnetic device 40 is controlled to be a second magnetic field strength, and the second magnetic field strength is smaller than the first magnetic field strength, so that the food materials in the storage compartment 21 can be frozen and preserved. The preservation and eating mode refers to a working mode that the food materials are not eaten in a short time and need to be preserved and eaten for a long time. Short-term and long-term are relatively general, for example, short-term times are understood to mean from 0 to 5 days, and long-term times are understood to mean from 6 days to one month, or even three months. Under the food storage mode, the operation of the user on the temperature gears of the storage chamber 21 can be acquired, the temperature gears comprise a first gear, a second gear and a third gear, the temperature of the first gear is lower than that of the second gear, and the temperature of the second gear is lower than that of the third gear. If the user has the selected temperature step within the first time period, the refrigeration device 30 is controlled to refrigerate the storage compartment 21 at the temperature corresponding to the selected temperature step. If the user does not select the temperature gear within the first time period, the refrigeration device 30 is controlled to refrigerate the storage compartment 21 at the temperature corresponding to the second gear. For example, the first time period may be 1 minute. In the preservation mode, the temperature of the storage compartment 21 can be divided into a first gear, a second gear and a third gear, which can be understood as a strong gear, a medium gear and a weak gear, for example, the first gear can correspond to a temperature in the range of-18 ℃ to-10 ℃, the second gear can correspond to a temperature in the range of-10 ℃ to-5 ℃, and the third gear can correspond to a temperature in the range of-5 ℃ to-1 ℃. The selection of the temperature of the storage compartment 21 can be obtained by the user, that is, the user can select the temperature of the storage compartment 21 according to the requirement, and then control the refrigeration temperature of the refrigeration device 30. Of course, if the user does not select the gear within the first time period, the control command is directly sent to the cooling device 30, and the cooling temperature of the cooling device 30 is selected as the second gear. The magnetic field strength of solenoid 40 may be controlled at this time to be in the range of 0hmt to 2hmt, and since the temperature of the compartment is low, the magnetic field strength in this case may be relatively small, and thus the second magnetic field strength may be smaller than the first magnetic field strength. Due to the low temperature and the magnetic field effect of the storage chamber 21, the meat food can be preserved for a long time. However, the material is frozen, so that the material is hard and difficult to cut.
204. And if the working mode of the storage compartment is a thawing mode, controlling the refrigerating device to adjust the temperature of the storage compartment to a third temperature, wherein the third temperature is higher than the second temperature, and controlling the magnetic field intensity of the electromagnetic device to be a third magnetic field intensity which is higher than the second magnetic field intensity so as to thaw the food materials in the storage compartment.
If the operation mode of the storage compartment 21 is the thawing mode, the refrigeration device 30 is controlled to adjust the temperature of the storage compartment 21 to a third temperature, which is higher than the second temperature, and the magnetic field strength of the electromagnetic device 40 is controlled to a third magnetic field strength, which is higher than the second magnetic field strength, so as to thaw the food material in the storage compartment 21. The thawing mode is a working mode for thawing food materials, so that a user can directly thaw the food materials in the storage eating mode for convenience of user operation, the food materials are not required to be taken out for thawing, the process of thawing the food materials is facilitated, and the refrigerator 1 is more intelligent. When the storage compartment 21 is in the thawing mode, the refrigeration temperature of the refrigeration device 30 is controlled to a third temperature, which may be a temperature in a temperature range, such as-5 ℃ to-2 ℃. The magnetic field strength of control solenoid 40 may be in a range of magnetic field strengths, such as 5-6 times the magnetic field strength in the food storage mode, for example, the magnetic field strength in the thaw mode may be in a range of 10hmt to 15 hmt. The main function of the electromagnetic device 40 in the thawing mode is to generate heat to heat the food material in the storage compartment 21. And, keep the temperature in the storage compartment 21 at-5 deg.C to-2 deg.C at this moment, can be convenient for cutting apart the meat food material, and can guarantee the juice of the meat does not lose, reach the effect that the meat unfreezes and keeps fresh.
In the refrigerator 1 and the control method of the refrigerator provided by the embodiment of the application, three working modes are set for the storage compartment 21 in the refrigerator 1, and different refrigeration temperatures of the refrigeration devices 30 and magnetic field strengths of the electromagnetic devices 40 are set for different working modes, so that the same storage compartment 21 can realize low-temperature storage and electromagnetic preservation of food materials, and can also realize control of unfreezing of the food materials by the control panel 50 through function keys, thereby facilitating unfreezing of a user on the food materials, and improving the user use experience.
