Detailed Description
The present invention will be described in detail below with reference to embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
Fig. 1 and 2 show a schematic structural diagram of the refrigerator, in which the refrigerator includes a box 1, a refrigerating chamber 4, a temperature-changing chamber 5 and a freezing chamber 6, evaporators 2 for refrigerating are provided in the refrigerating chamber 4, the temperature-changing chamber 5 and the freezing chamber 6, and a compressor 3 for supplying a refrigerant is further provided in the refrigerator; an input module 7 is provided at the front of the refrigerator, and a screen and a number of input buttons may be provided in the input module 7 in order to facilitate a user to input information. As shown in fig. 2, the input module 7 is disposed on the door of the refrigerating chamber 4, and it is understood that the input module 7 may be disposed on other regions, for example, the door of the temperature-changing chamber 5 or the freezing chamber 6. Inside the refrigerator, electricity in the power grid (for example, 220V in china) can be used to directly power the magnetic field generator 9, or the electricity in the power grid can be converted into direct current to power the magnetic field generator 9.
An embodiment of the present invention provides a refrigerator, as shown in fig. 3, including a storage compartment (e.g., a refrigerating compartment 4, a temperature-changing compartment 5, a freezing compartment 6, etc.) for storing food items and an evaporator 2 for adjusting a temperature of the storage compartment;
the refrigerator also comprises the following modules: an input module 7 for inputting a food type of the food, a weight sensor 8 for acquiring a food weight of the food, a magnetic field generator 9 for generating a static magnetic field and/or an alternating magnetic field in the storage compartment; here, to facilitate the measurement of the weight of the food, a weight sensor 8 may be provided at the bottom of the storage compartment.
And the control system 10 is used for generating a target temperature value and a target magnetic field strength value of the storage chamber based on the type and the weight of the food, controlling the evaporator 2 to adjust the temperature of the storage chamber to the target temperature value, and controlling the magnetic field generator 9 to adjust the magnetic field strength of the storage chamber to the target magnetic field strength value, wherein the target temperature value is greater than or equal to 7 ℃ and less than or equal to 0 ℃.
In use, after a user stores an article in the storage compartment, the type of the food stored in the storage compartment can be input through the input module 7, the control system 10 receives the type of the food, and then the user closes the door; in the refrigerator, the control system 10 stores optimum target temperature values corresponding to a plurality of food types (the temperature is beneficial to fresh keeping and does not cause food to be frozen in a large scale), and in operation, the control system 10 obtains the target temperature values corresponding to the food types (for example, the target temperature value of strawberry is-2 ℃, the target temperature value of cod is-1 ℃, the target temperature value of beef is-2 ℃, the target temperature value of pork is-2 ℃, and the like), and then adjusts the temperature of the storage compartment according to the target temperature values. In the refrigerator, a plurality of food magnetic field strength values (for example, in a/m.g) corresponding to the unit weight of the food are stored, and the control system acquires the weight of the food from the weight sensor 8, obtains a target magnetic field strength value, and adjusts the magnetic field strength of the storage compartment according to the target magnetic field strength value. Optionally, a database may be provided in the control system, and the database stores a plurality of food types, and a target temperature value and a unit weight food magnetic field intensity value corresponding to each food type.
Here, in the refrigerator, the control system 10 adjusts the temperature and the magnetic field strength of the storage compartment according to the type and the weight of the food, so that the food in the storage compartment is at an appropriate temperature, the magnetic field strength is adjusted by the magnetic field generator in a micro-frozen state, and when sterilization and preservation are required, the magnetic field strength in the storage compartment can be reduced; and the magnetic field intensity is increased, so that the freezing speed can be increased, the formation of large ice crystals can be reduced, and the appearance and nutrition of the thawed meat can be maintained.
Here, it has been found through long-term practice of the inventors that the size of ice crystals in food can be effectively reduced when the storage temperature of the storage compartment is between-7 ℃ and 0 ℃.
Preferably a magnetic field strength sensor 11 for detecting the magnetic field strength in the storage compartment. Here, the control system 10 obtains the magnetic field strength in the storage compartment from the magnetic field strength sensor 11, and increases the strength value of the magnetic field generated by the magnetic field generator 9 when the magnetic field strength is smaller than the target magnetic field strength value; conversely, when the magnetic field strength is greater than the target magnetic field strength value, the strength value of the magnetic field generated by the magnetic field generator 9 is decreased.
Preferably, a temperature sensor for detecting the temperature in the storage compartment. Here, the control system may obtain the temperature in the storage compartment from the temperature sensor, and when the temperature is less than the target temperature value, the temperature of the storage compartment needs to be increased; conversely, when the magnetic field strength is greater than the target temperature value, the temperature of the storage compartment needs to be reduced.
Preferably, as shown in fig. 4, the storage compartment is provided with a magnetically permeable inner shell 12 and an outer shell 13, and the magnetic field generator 9 comprises a first electromagnetic coil 14, the first electromagnetic coil 14 being capable of generating a complete magnetic field path in the space between the magnetically permeable inner shell 12 and the outer shell 13.
Here, normally, the storage compartment has a cubic space formed by five faces and the door body, and these five faces are the magnetically conductive inner shell 12 of the storage compartment, it can be understood that the outer shell 13 is further disposed outside the magnetically conductive inner shell 12, and a space is formed between the magnetically conductive inner shell 12 and the outer shell 13, and the first electromagnetic coil 14 is disposed in the space, so that when the first electromagnetic coil 14 is energized, there is a complete magnetic field path in the space, and the magnetic field enters the storage compartment along the magnetically conductive inner shell 12, so that an uneven magnetic field is formed in the storage compartment, and when the circuit of the first electromagnetic coil 14 is increased, the magnetic field is saturated, and the magnetic field "overflows" into the storage compartment. Here, the first electromagnetic coil 14 may be provided in a space between the magnetically permeable inner casing 12 and the outer casing 13, or may be a coil wound along a partial space between the magnetically permeable inner casing 12 and the outer casing 13, and when the coil is energized, a magnetic field is generated in the partial space.
Preferably, the storage compartment is provided with a magnetically permeable inner shell 12 and an outer shell 13, and the magnetic field generator 9 comprises a first electromagnetic coil 14 and a second electromagnetic coil 15 connected in series, the first electromagnetic coil 14 and the second electromagnetic coil 15 being capable of generating a magnetic field in the space between the magnetically permeable inner shell 12 and the outer shell 13. Here, since the first electromagnetic coil 14 and the second electromagnetic coil 15 are in a series relationship, when the magnetic field direction between the first electromagnetic coil 14 and the second electromagnetic coil 15 is the same, the magnetic field strength in the storage compartment can be greatly increased; and conversely the magnetic field strength in the storage compartment can be reduced.
Preferably, the storage compartment is provided with a magnetic conductive inner shell 12 and an outer shell 13, the magnetic field generator 9 includes a first electromagnetic coil 14, the first electromagnetic coil 14 can generate a magnetic field in a space between the magnetic conductive inner shell 12 and the outer shell 13, the magnetic conductive inner shell 12 is provided with a hole and a magnetic conductive partition plate 16 hinged to the magnetic conductive inner shell 12, and the magnetic conductive partition plate 16 can move in the space between the magnetic conductive inner shell 12 and the outer shell 13. Here, the magnetic conductive partition 16 is hinged in the magnetic conductive inner shell 12 through a hinge, and when the plane where the magnetic conductive partition 16 is located is not parallel to the direction of the magnetic field, a throttling effect occurs, so that the magnetic field at the position close to the coil is enhanced, and the magnetic field intensity in the storage compartment is weakened by throttling the outside.
Here, the control system 10 may also have an alarm function, which may be performed if one or more of the index parameters in the storage compartment is detected to be out of the normal range. For example: if the temperature is not in the range of-7 ℃ to 0 ℃ and the temperature is not in the range after being adjusted by the evaporator 3, an alarm is required; and when the time of the magnetic field intensity abnormity exceeds a preset value, alarming is required, and the like.
Here, when the door of the storage compartment is opened, there is a possibility that the magnetic field in the storage compartment leaks and the human health may be harmed, and therefore, when the door is opened, the power supply to the magnetic field generator 9 needs to be stopped.
An embodiment two of the present invention provides a method for adjusting temperature and magnetic field strength of a storage compartment in a refrigerator according to the embodiment one, as shown in fig. 7, including the following steps:
step 701: acquiring the type of the food stored in the storage chamber and receiving the weight value W of the food sent by the weight sensor 8;

Step 703: and adjusting the temperature of the storage chamber to T and the magnetic field intensity to E.
Preferably, the method also comprises the following steps,
step 704: acquiring the magnetic field intensity E' detected by the magnetic field intensity sensor 11; when the difference value between E' and E is determined to be larger than a first preset value, reducing the magnetic field intensity of the magnetic field generated by the magnetic field generator 9; when it is determined that the difference between E' and E is smaller than the second preset value, the magnetic field strength of the magnetic field generated by the magnetic field generator 9 is increased.
The embodiment of the invention also provides a device for adjusting the temperature and the magnetic field intensity of the refrigerator in the first embodiment, which comprises the following modules:
an information acquisition module, configured to acquire the type of food stored in the storage compartment, and receive the food weight value W sent by the weight sensor 8;
