[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0041] The present application provides a fresh-keeping compartment, which is applied to a refrigerator and is used to store items with specific requirements for temperature, humidity, etc. or items with high fresh-keeping requirements. The refrigerator may be a single-door, double-door, side-by-side, French, cross-door, or other type of refrigerator. For example, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the fresh-keeping space provided in the embodiment of the present application. Figure 2 The fresh-keeping compartment 100 includes a compartment body 110 , a magnetic field generating assembly 120 and a magnetic material layer 130 .

[0042] Among them, the chamber body 110 has a first side wall 1121 and a second side wall 1111 that are relatively spaced apart, and a fresh-keeping space 1112 is formed between the first side wall 1121 and the second side wall 1111; the magnetic field generating component 120 is installed on the first side wall 1121, and is used to apply a magnetic field to the fresh-keeping space 1112; the magnetic material layer 130 is arranged on the surface of the second side wall 1111 facing and / or away from the first side wall 1121.

[0043] It should be noted that the magnetic material layer 130 itself has magnetism, and can generate a magnetic field by itself, and can also reflect the electromagnetic waves emitted by the magnetic field generating component 120 to form a reflected magnetic field in the fresh-keeping space 1112. The magnetic material layer 130 may include magnetic powder material. Exemplarily, the manufacturing process of the magnetic material layer 130 includes spraying or coating the magnetic coating on the second side wall 1111 and then air-drying or baking to form the magnetic material layer 130, wherein the magnetic coating includes magnetic powder, adhesive and solvent.

[0044] In actual application, due to the characteristics of magnetic field generation, the magnetic field strength generated by the magnetic field generating assembly 120 gradually decreases from the area close to the first side wall 1121 to the area close to the second side wall 1111 inside the fresh-keeping space 1112. The fresh-keeping compartment 100 provided in the embodiment of the present application can enhance the magnetic field strength of the area close to the second side wall 1111 inside the fresh-keeping space 1112 by setting the magnetic material layer 130 on the surface of the second side wall 1111, and improve the uniformity of the magnetic field in each area of ​​the fresh-keeping space 1112. In addition, the reflected magnetic field formed by the magnetic material layer 130 can be distributed to the corner area of ​​the fresh-keeping space 1112, further ensuring that each area of ​​the fresh-keeping space 1112 has a magnetic field distribution, thereby improving the fresh-keeping effect of the fresh-keeping space 1112.

[0045] For further information, see Figure 3 , Figure 3 The exploded view of the fresh-keeping space provided in the embodiment of the present application. The compartment body 110 includes a drawer assembly 111 and a partition 112 .

[0046] Among them, the drawer assembly 111 forms a fresh-keeping space 1112 with an opening 1113; the partition 112 is arranged at the opening 1113 to close the fresh-keeping space 1112; the first side wall 1121 is formed on one of the drawer assembly 111 and the partition 112, and the second side wall 1111 is formed on the other of the drawer assembly 111 and the partition 112.

[0047] For example, the first side wall 1121 is formed on the partition 112, and the second side wall 1111 is formed on the drawer assembly 111. In some embodiments, the drawer assembly 111 further includes a circumferential side wall 1114 disposed around the edge of the second side wall 1111, and the second side wall 1111 and the circumferential side wall 1114 enclose a fresh-keeping space 1112, and the magnetic material layer 130 is further disposed on the circumferential side wall 1114 on a surface located in the fresh-keeping space 1112 and / or away from the fresh-keeping space 1112. In this way, the multiple side walls of the drawer assembly 111 forming the fresh-keeping space 1112 can all generate and reflect a magnetic field, thereby ensuring that each area of ​​the fresh-keeping space 1112 is evenly distributed with a magnetic field, thereby improving the fresh-keeping effect of the fresh-keeping space 1112.

[0048] The magnetic field generating assembly 120 is installed on the surface of the first side wall 1121 facing and / or facing away from the second side wall 1111. In this way, the magnetic field generated by the magnetic field generating assembly 120 can directly enter the fresh-keeping space 1112 through the opening 1113 without being blocked or reflected to the outside of the fresh-keeping space 1112. Preferably, the magnetic field generating assembly 120 is installed on the surface of the first side wall 1121 facing the second side wall 1111, and the magnetic material layer 130 is also arranged on the surface of the first side wall 1121 facing away from the second side wall 1111. It can be understood that by arranging the magnetic material layer 130 on the side of the first side wall 1121 away from the fresh-keeping space 1112, a reflection effect can be formed from the back side, so that the magnetic field generated by the magnetic field generating assembly 120 on the side away from the fresh-keeping space 1112 is reflected into the fresh-keeping space 1112, thereby improving the magnetic field utilization rate of the magnetic field generating assembly 120.

[0049] The magnetic field generating assembly 120 includes a mounting frame 121 and a magnetic field generating element 122. The mounting frame 121 is mounted on the surface of the first side wall 1121 facing the second side wall 1111. The magnetic field generating element 122 is disposed in the mounting frame 121 and is used to apply a magnetic field to the fresh-keeping space 1112. The magnetic field generating element 122 can be an electromagnetic coil, an electromagnet, a permanent magnet or other types. Preferably, the magnetic field generating element 122 is an electromagnetic coil so that the generated magnetic field has better uniformity, higher magnetic field strength, and higher control accuracy.

[0050] In some embodiments, an air inlet 1115 is provided on the circumferential side wall 1114, and the air inlet 1115 is used to communicate with the cooling air duct of the refrigerator to blow cold air into the fresh-keeping space 1112. It can be understood that the fresh-keeping compartment 100 not only needs magnetic field preservation, but also needs to keep the fresh-keeping space 1112 at a specific low temperature to achieve a better fresh-keeping effect on the internal items.

[0051] The fresh-keeping compartment 100 provided in the embodiment of the present application is provided with a magnetic material layer 130 on multiple side walls of the drawer assembly 111, so that the magnetic material layer 130 radiates a magnetic field to the fresh-keeping space 1112 from multiple directions around the fresh-keeping space 1112, and the magnetic field generating assembly 120 is arranged on the partition 112. The magnetic material layer 130 also reflects the electromagnetic waves generated by the magnetic field generating assembly 120 to form an emitting magnetic field, thereby ensuring that the magnetic field is evenly distributed in each area of ​​the fresh-keeping space 1112, thereby improving the fresh-keeping effect of the fresh-keeping space 1112.

[0052] The present application also provides a refrigerator, for example, see Figure 4 , Figure 4 The refrigerator 10 includes a refrigerating compartment 200 and the above-mentioned fresh-keeping compartment 100 , and the fresh-keeping compartment 100 is disposed in the refrigerating compartment 200 .

[0053] Exemplarily, the refrigerator 10 further includes a cooling air duct (not shown in the figure), which is connected to the fresh-keeping space 1112 and is used to provide cold air to the fresh-keeping space 1112. It should be noted that the refrigerator 10 includes a refrigeration cycle system, and the evaporator in the refrigeration cycle system is arranged in the cooling air duct, and the evaporator performs heat exchange with the surrounding environment to cool the air in the cooling air duct to form cold air.

[0054] Among them, see Figure 5 , Figure 5 The exploded view of the refrigeration compartment and the fresh-keeping compartment provided in the embodiment of the present application. The refrigeration compartment 200 includes a refrigeration box 210 and a refrigeration air duct 220 .

[0055] Among them, the fresh-keeping compartment 100 is arranged in the refrigerator box 210; the refrigeration air duct 220 is installed in the refrigerator box 210, and the refrigeration air duct 220 includes a connected air inlet (not shown in the figure) and an air supply outlet 221, the air inlet is used to communicate with the cold air duct of the refrigerator, and the air supply outlet 221 is connected to the fresh-keeping space 1112.

[0056] In actual application, the cold air generated by the cooling air duct enters the refrigeration air duct 220 through the air inlet, and flows into the fresh-keeping space 1112 through the air supply port 221 after being guided by the refrigeration air duct 220 to preserve the items in the fresh-keeping space 1112.

[0057] The refrigeration air duct 220 is installed on the back plate of the refrigerator liner 210. One of the drawer assembly 111 and the refrigerator liner 210 is provided with a slide rail, and the other is provided with a slide groove, so that the drawer assembly 111 is slidably connected with the refrigerator liner 210 to slide out or slide into the refrigerator liner 210. The partition 112 is fixedly installed on the refrigerator liner 210, and during the sliding process of the drawer assembly 111, the partition 112 at least closes a part of the opening 1113.

[0058] The refrigerator 10 provided in the embodiment of the present application can enhance the magnetic field strength of the area near the second side wall 1111 inside the fresh-keeping space 1112 by arranging the magnetic material layer 130 on the surface of the second side wall 1111 of the fresh-keeping compartment 100, and improve the uniformity of the magnetic field in each area of ​​the fresh-keeping space 1112. In addition, the reflected magnetic field formed by the magnetic material layer 130 can be distributed to the corner area of ​​the fresh-keeping space 1112, further ensuring that each area of ​​the fresh-keeping space 1112 has a magnetic field distribution, thereby ensuring the fresh-keeping effect of the fresh-keeping space 1112.
