With the improvement of people's living standards, higher requirements are placed on the preservation effect of refrigerators. Theoretical studies have found that magnetic fields have a great influence on the low-temperature storage of food, because the magnetic field limits the free path of water molecules to a certain extent, so that the growth of crystal nuclei is inhibited, so that food is less likely to freeze at low temperatures, so that refrigeration can be achieved at a certain sub-zero temperature, or the ice crystals produced when the food is frozen can be reduced to reduce damage to the food cells. Therefore, applying a magnetic field to the food can play a good auxiliary role in the low-temperature storage of the food and improve the preservation effect of the food.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment, the refrigerator includes a box body 100, a door body 200 and a magnetic field device 300. The box body 100 includes a box body foam layer 110 and a box body 120, the box body 120 wraps the box body foam layer 110, and the box body 100 forms a storage compartment 101. The door body 200 includes a door body foam layer 210 and a door body 220, the door body 220 wraps the door body foam layer 210, and the door body 200 is used to open and close the storage compartment 101. The magnetic field device 300 includes a magnetic field generating member 310 and a shim plate 320, the shim plate 320 is arranged on the side of the magnetic field generating member 310 away from the storage compartment 101, the magnetic field device 300 is arranged in the door body foam layer 210, and the magnetic field device 300 is used to generate a magnetic field in the storage compartment 101.

[0042] Reference Figure 1 As shown, specifically, the box body 100 forms a storage compartment 101, and the storage compartment 101 has an opening toward the front of the refrigerator. The door body 200 is pivotally connected to the box body 100, so that the door body 200 can open and close the front opening of the storage compartment 101 by rotating relative to the box body 100.

[0043] Furthermore, the refrigerator also includes an evaporator 400 and a refrigeration fan 500. The evaporator 400 can release cold energy, and the refrigeration fan 500 can generate a refrigeration airflow carrying cold energy and make the refrigeration airflow flow to the storage compartment 101 to cool the storage compartment 101.

[0044] Reference Figure 1 As shown, specifically, the box body 100 forms a large space, and by arranging a partition or other structure in the large space formed by the box body 100, the large space formed by the box body 100 is divided into a plurality of areas, wherein one of the separated areas is used as a storage room 101. In addition, a refrigeration room 102 is also separated, and the evaporator 400 and the refrigeration fan 500 are arranged in the refrigeration room 102.

[0045] That is to say, the box body 100 only constitutes a part of the side wall of the storage compartment 101 .

[0046] It should be noted that, in some other embodiments, the side walls of the refrigerator storage compartment may also be entirely composed of a box body.

[0047] In addition, it should be noted that the box body may also form a plurality of storage compartments, and the storage compartments may be used to achieve different functions, such as a refrigerated storage compartment, a frozen storage compartment, a variable temperature storage compartment, etc. For the refrigerator of the present application, those skilled in the art may configure the specific number, function and layout of the storage compartments according to the requirements.

[0048] Continue to refer to Figure 1 As shown, the refrigerator includes a magnetic field device 300, which is separately arranged in the door foam layer 210. In addition, the magnetic field device 300 corresponds to the storage compartment 101 from the front of the storage compartment 101, thereby generating a magnetic field in the storage compartment 101, so that the food in the storage compartment 101 can be stored under the action of the magnetic field.

[0049] It should be noted that, when the refrigerator has multiple storage compartments, corresponding magnetic field devices can be provided for one or more of the storage compartments. In other words, the refrigerator can have ordinary storage compartments and storage compartments capable of realizing magnetic field storage.

[0050] In addition, the storage compartment of the refrigerator used to achieve magnetic field storage can use a separate refrigeration system, or can share a refrigeration system with an ordinary refrigerated storage compartment, or can also share a refrigeration system with an ordinary frozen storage compartment.

[0051] Reference Figure 1 and Figure 2As shown, further, the magnetic field device 300 includes a magnetic field generating member 310 and a shimming plate 320, and the shimming plate 320 is arranged on the side of the magnetic field generating member 310 away from the storage compartment 101. The shimming plate 320 is made of a magnetic conductive material, such as silicon steel material. The shimming plate 320 can guide the magnetic field generated by the magnetic field generating member 310, thereby improving the uniformity of the magnetic field in the storage compartment 101. Specifically, the magnetic field generating member 310 is an electromagnetic coil, and the electromagnetic coil can generate a magnetic field after being energized.

[0052] In the scheme of this embodiment, by setting a magnetic field device 300 in the foaming layer of the refrigerator, the magnetic field device 300 includes a magnetic field generating member 310 and a uniform magnetic plate 320. The magnetic field generating member 310 can generate a magnetic field, and the uniform magnetic plate 320 can guide the magnetic field generated by the magnetic field generating member 310, so that the magnetic field generated by the magnetic field generating member 310 is concentrated in the storage compartment 101, and the uniformity of the magnetic field in the storage compartment 101 is improved, so that the food in the storage compartment 101 is subjected to a uniform magnetic field, so as to achieve low-temperature storage of the food under the action of the magnetic field, and improve the preservation effect of the food. In addition, the magnetic field device 300 is set in the foaming layer to avoid the magnetic field device 300 occupying the effective storage space of the refrigerator. At the same time, the foaming layer plays a role in fixing and supporting the magnetic field device 300, simplifies the installation and fixing work of the magnetic field device 300, and can play a role in wrapping and protecting the magnetic field device 300. It can also reduce the influence of the heat of the electromagnetic coil on the storage compartment 101 when it is working.

[0053] Furthermore, by disposing the magnetic field device 300 in the door foaming layer 210, since the structure of the refrigerator door 200 is simpler, the installation of the magnetic field device 300 can be made more convenient.

Specifically, the permanent magnet sheet 312 is arranged in the area surrounded by the electromagnetic coil 311, and the permanent magnet sheet 312 can be smaller than the area surrounded by the electromagnetic coil 311, or can be exactly equal, so that the electromagnetic coil 311 fits the side of the permanent magnet sheet 312.

[0057] By using electromagnetic coils and permanent magnets to form a magnetic field generating element, it is beneficial to increase the magnetic field strength.

[0058] like Figure 5 As shown, in one embodiment, the magnetic field device 300 is separately disposed in the box foam layer 110. Specifically, the magnetic field device 300 is disposed in the box foam layer 110 located at the bottom of the storage compartment 101. Thus, the magnetic field device 300 can be closer to the food placed in the storage compartment 101, thereby improving the magnetic field effect.

The magnetic field device 300 is arranged in the box foam layer 110. Specifically, the magnetic field device 300 is arranged in the box foam layer 110 located on the right side of the storage compartment 101.

[0065] It should be noted that, in some other embodiments, the magnetic field device may also be disposed in the foam layer of the box body located on the left side, top side or rear side of the storage compartment.

[0066] like Fig.10 As shown, in one embodiment, the refrigerator includes two magnetic field devices 300, and the two magnetic field devices 300 are respectively arranged on different sides of the storage compartment 101. Specifically, one magnetic field device 300 is arranged in the box foam layer 110 located at the bottom of the storage compartment 101, and the other magnetic field device 300 is arranged in the box foam layer 110 located on the right side of the storage compartment 101.

[0067] like Fig.11 As shown, in one embodiment, two magnetic field devices 300 are respectively arranged on opposite sides of the storage compartment 101. Specifically, one magnetic field device 300 is arranged in the box foam layer 110 located on the left side of the storage compartment 101, and the other magnetic field device 300 is arranged in the box foam layer 110 located on the right side of the storage compartment 101.

[0068] like Fig.12 As shown, in one embodiment, two magnetic field devices 300 are respectively arranged on opposite sides of the storage compartment 101. Specifically, the two magnetic field devices 300 are respectively arranged on the box foam layer 110 and the door foam layer 210, so that the two magnetic field devices 300 are respectively located on the front and back sides of the storage compartment 101.

[0069] By arranging the two magnetic field devices 300 on different sides of the storage compartment 101 , it helps to improve the uniformity of the magnetic field in the storage compartment 101 .

[0070] Furthermore, by respectively arranging the two magnetic field devices 300 on the box foam layer 110 and the door foam layer 210 , the two magnetic field devices 300 are respectively located on the front and rear sides of the storage compartment 101 , making the installation of the magnetic field devices 300 more convenient.

[0071] It should be noted that, in some other embodiments, the magnetic field device may also be respectively arranged at positions on other different sides of the storage compartment, for example, at the left side and rear side, the left side and bottom side, the left side and top side, the left side and front side, the right side and rear side, the right side and top side, the right side and front side, the top side and bottom side, the top side and rear side, the top side and front side, the front side and bottom side, or the rear side and bottom side.
