For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the refrigerator includes a storage compartment 10, which is used to place items to be stored; a pulsed magnetic field device 100, which includes a power supply module 110 and at least one electromagnetic coil 120, and the power supply module 110 is used to supply power to the electromagnetic coil 120 so that the electromagnetic coil 120 generates a pulsed magnetic field in the storage compartment 10; and at least one static magnetic field device 200, which is used to generate a static magnetic field in the storage compartment 10.

[0033] like Figure 1 and Figure 2 As shown, specifically, the refrigerator includes a box body 300, which forms a storage compartment 301; and a storage container 400, which is arranged in the storage compartment 301, and the storage container 400 forms a storage compartment 10, and the pulsed magnetic field device 100 and the static magnetic field device 200 are installed in the storage container 400.

[0034] Reference Figure 1As shown, specifically, the box body 100 is formed with a plurality of storage compartments 301, and the plurality of storage compartments 301 are distributed along the longitudinal direction of the box body 100. It should be noted that the plurality of storage compartments 301 can be used to achieve different storage functions, such as refrigeration, freezing or temperature change, etc. For the refrigerator of the present application, those skilled in the art can configure the number, function and layout of the specific storage compartments of the box body according to the requirements, and the storage container can be arranged in one or more of the storage compartments.

[0035] Reference Figure 1 and Figure 2 As shown, the storage container 400 is a box-shaped structure having a top side wall, a bottom side wall, a left side wall, a right side wall and a rear side wall, and the five side walls of the storage container 400 together enclose a storage compartment 10. The storage container 400 is placed in the receiving compartment 301. The storage compartment 10 is used to place the objects to be stored. The pulse magnetic field device 100 includes a power supply module 110 and an electromagnetic coil 120. The power supply module 110 can be a rechargeable battery or a high-voltage capacitor. The power supply module 110 supplies power to the electromagnetic coil 120 so that the electromagnetic coil 120 generates a pulse magnetic field, that is, the power supply mode 100 supplies a current with a periodic change in size to the electromagnetic coil 120, so that the electromagnetic coil 120 generates a pulse magnetic field with a periodic change in strength. The pulse magnetic field has a good sterilization effect on the food in the storage compartment 10, thereby inhibiting the growth of microorganisms.

[0036] Furthermore, the static magnetic field device 200 is used to generate a static magnetic field in the storage compartment 10, that is, a magnetic field with constant strength. The magnetic field with constant strength can assist the storage process of food materials, so that meat food materials can be stored without freezing at sub-zero temperatures, that is, they are still refrigerated storage in essence, thereby greatly reducing the refrigeration temperature of meat and further inhibiting the growth of microorganisms. The static magnetic field device 200 can be a permanent magnet sheet or a coil, which generates a constant magnetic field by passing a constant current.

[0037] It should be noted that the pulsed magnetic field device 100 can be configured to be activated when the food is just placed in the storage compartment 10, so as to perform preliminary and efficient sterilization on the food with higher temperature, and the static magnetic field device 200 can be configured to be activated after the pulsed magnetic field device 100 stops or to be activated at all times.

[0038] In the scheme of this embodiment, by arranging a pulsed magnetic field device 100 and a static magnetic field device 200 in the refrigerator, the pulsed magnetic field device 100 can generate a pulsed magnetic field in the storage compartment 10, and the static magnetic field device 200 can generate a static magnetic field in the storage compartment 10. The pulsed magnetic field has a better inhibitory effect on the growth of microorganisms, and can effectively inhibit the growth of microorganisms, thereby being able to quickly and effectively sterilize the food with a higher temperature that has just been put into the refrigerator. The static magnetic field generated by the static magnetic field device 200 can play an auxiliary role in the storage of food, so that the food can be refrigerated and stored at sub-zero temperatures, greatly reducing the refrigeration temperature of the food, and further inhibiting the growth of microorganisms. The pulsed magnetic field and the static magnetic field cooperate with each other, and can effectively inhibit the growth of microorganisms during the entire storage cycle of the food, thereby improving the preservation effect of the food.

[0039] In addition, by arranging the storage container 400 in the box body 300, the storage container 400 forms a storage compartment 10, and the pulsed magnetic field device 100 and the static magnetic field device 200 are installed in the storage container 400, so that the pulsed magnetic field device 100, the static magnetic field device 200 and the storage container 400 can form a whole, so that the pulsed magnetic field device 100, the static magnetic field device 200 and the storage container 400 can be assembled and then transferred to the box body 100, thereby facilitating the installation of the pulsed magnetic field device 100 and the static magnetic field device 200. In addition, the pulsed magnetic field device 100 and the static magnetic field device 200 can also be taken out from the storage compartment 301 together with the storage container 400, so that the disassembly of the pulsed magnetic field device 100 and the static magnetic field device 200 is more convenient.

[0040] It should be noted that in some other embodiments, the storage container may not be provided, but the storage compartment may be directly formed by the box body.

[0041] like Figure 1 and Figure 2 As shown, further, the electromagnetic coil 120 is arranged on the top side wall of the storage container 400 and is located outside the storage compartment 10, and the power supply module 110 is arranged on the rear side wall of the storage container 400 and is located outside the storage compartment 10. Specifically, the top side wall of the storage container 400 forms a top interlayer space 401, the rear side wall of the storage container 400 forms a rear interlayer space 402, the electromagnetic coil 120 is arranged in the top interlayer space 401, and the power supply module 110 is arranged in the rear interlayer space 402.

[0042] Reference Figure 1 and Figure 2As shown, specifically, the top side wall of the storage container 400 has a certain thickness and is hollow inside, so that a top interlayer space 401 is formed on the top side wall of the storage container 400. The rear side wall of the storage container 400 has a certain thickness and is hollow inside, so that a rear interlayer space 402 is formed on the rear side wall of the storage container 400. The electromagnetic coil 120 is installed in the top interlayer space 401, and the power supply module 110 is installed in the rear interlayer space 402, so that the pulsed magnetic field device 100 is installed in the storage container 400.

[0043] By providing a top interlayer space 401 on the top side wall of the storage container 400, providing a rear interlayer space 402 on the rear side wall of the storage container 400, providing the electromagnetic coil 120 in the top interlayer space 401, and providing the power supply module 110 in the rear interlayer space 402, the storage container 400 can protect the electromagnetic coil 120 and the power supply module 110 on the one hand, and on the other hand, the electromagnetic coil 120 and the power supply module 110 will not affect the internal space of the storage container 400, that is, the storage compartment 10. In addition, because the rear side of the refrigerator is generally a refrigeration zone, providing the power supply module 110 on the rear side wall of the storage container 400 helps to reduce the effect of the heat generated by the power supply module 110 on the storage compartment 10.

[0044] It should be noted that, in some other embodiments, the side walls of the storage container may also be a solid wall, and the electromagnetic coil and the power supply module are arranged in the storage compartment, or fixed on the outer surface of the side wall of the storage container.

[0045] like Figure 1 and Figure 2 As shown, an air inlet 403 is formed on the rear side of the storage container 400 , and the air inlet 403 is connected to the top interlayer space 401 so as to guide the cold air flow entering through the air inlet 403 from the back to the front through the top interlayer space 401 .

[0046] Specifically, the box body 300 is formed with a refrigeration cavity 302, and an evaporator (not marked in the figure) and a fan (not marked in the figure) are arranged in the refrigeration cavity 302. The air inlet 403 is formed at the top of the rear side of the storage container 400, that is, at the rear end of the top interlayer space 401. The evaporator can generate cold energy in the refrigeration cavity 302, and the fan can generate cold air, which transports the cold energy in the refrigeration cavity to the air inlet 403, and flows into the top interlayer space 401 through the air inlet 403, and then flows forward along the top interlayer space 401.

[0047] By allowing the cold air to flow through the top interlayer space 401, it is possible to prevent the cold air from blowing directly onto the food in the storage compartment 10, thereby preventing the food from freezing due to excessively low temperature and losing the refrigerated state. At the same time, it is helpful to guide the cold air to flow from the top of the storage compartment 10 through the entire storage compartment 10. Since the cold air has a tendency to sink, it is helpful to evenly cool the entire storage compartment 10 and improve the temperature uniformity of the storage compartment 10.

[0048] like Figure 1 and Figure 2 As shown, further, the refrigerator also includes a drawer 500, which is arranged in the storage compartment 10. The drawer 500 is used to place items to be stored. The front end plate of the drawer 500 is formed with an air flow path 501. The air flow path 501 is used to receive the cold air flow flowing out from the front end of the top interlayer space 401 and guide the cold air flow from top to bottom.

[0049] Reference Figure 1 and Figure 2 As shown, specifically, the drawer 500 is pullable and arranged in the storage compartment 10, and the food is placed in the drawer 500, that is, placed in the storage compartment 10. The front end plate of the drawer 500 is provided with a wind path 501, the top of the front end plate of the drawer 500 is provided with a wind hole 502, and the front end of the top side wall of the storage container 400 is provided with an air outlet hole 404. When the cold air flows along the top interlayer space 401 to the front end of the top interlayer space 401, the cold air flows out from the air outlet hole 404, flows into the wind path 501 through the wind hole 502, and then flows from top to bottom along the wind path 501.

[0050] By setting up an air passage 501 on the front end panel of the drawer 500, cold air can enter the air passage 501 of the drawer 500 from the top interlayer space 401 of the storage container 400, so that the cold air can flow through the top side and the front side of the food storage area, thereby improving the refrigeration efficiency while avoiding cold air blowing directly on the food.

[0051] It should be noted that in some other embodiments, drawers may not be provided, and the cold air flow flows out from the front end of the top interlayer space and diffuses freely in the accommodating chamber.

[0052] like Figure 2 As shown, an air outlet gap 20 is provided between the outer surface of the bottom wall of the drawer 500 and the inner surface of the bottom side wall of the storage container 400, and a return air port 405 is provided on the rear side of the storage container 400, so that the cold air flowing out from the bottom of the front end panel of the drawer 500 flows into the air outlet gap 20, and flows from front to rear to the return air port 405 through the air outlet gap 20, and then flows out of the storage compartment 10 through the return air port 405.

[0053] Specifically, a ventilation hole 503 is provided at the bottom of the front end panel of the drawer 500. The cold air in the air passage 501 flows out from the ventilation hole 503 and then enters the air outlet 20. The cold air flows from front to back along the air outlet 20 until it flows to the return air port 405 and flows out of the storage compartment 10 from the return air port 405.

[0054] By providing an air gap 20 between the outer surface of the bottom wall of the drawer 500 and the inner surface of the bottom side wall of the storage container 400, the cold air flowing out of the air passage 501 can enter the air gap 20 and flow from front to back along the air gap 20, so that the cold air flows through the top side, front side and bottom side of the food storage area, thereby helping to further improve the refrigeration efficiency.

[0055] like Figure 3 As shown, in one embodiment, the pulsed magnetic field device 100 includes two electromagnetic coils 120, and the two electromagnetic coils 120 are respectively arranged on opposite sides of the storage compartment 10. Specifically, the two electromagnetic coils 120 are arranged on the top and bottom sides of the storage container 400. The top side wall of the storage container 400 is formed with a top interlayer space 401, and the electromagnetic coil 120 on the top side is arranged in the top interlayer space 401. The electromagnetic coil 120 on the bottom side is arranged in the storage compartment 10 and is arranged close to the bottom side wall of the storage container 400. The rear side wall of the storage container 400 is formed with a rear interlayer space 402, and the power supply module 110 is arranged in the rear interlayer space 402, and the power supply module 110 supplies power to the two electromagnetic coils 120.

[0056] By providing two electromagnetic coils 120, the two electromagnetic coils 120 generate a pulse magnetic field to sterilize the food, which helps to further improve the sterilization effect.

[0057] It should be noted that in some other embodiments, the two electromagnetic coils may be respectively arranged on the left and right sides of the storage room. In addition, in the case where no storage container is provided, two electromagnetic coils may be provided, and the two electromagnetic coils may be both located inside the storage room, or both located outside the storage room, or one may be inside the storage room and the other outside the storage room.

[0058] like Figure 3 As shown, further, the refrigerator includes two static magnetic field devices 200, and the two static magnetic field devices 200 are respectively arranged on opposite sides of the storage compartment 10. Specifically, the two static magnetic field devices 200 are arranged on the top side and the bottom side of the storage container 400. The static magnetic field device 200 on the top side is arranged in the top interlayer space 401. The electromagnetic coil 120 on the bottom side is arranged in the storage compartment 10 and is arranged close to the bottom side wall of the storage container 400.

[0059] By providing two static magnetic field devices 200 , which are respectively located at two sides of the storage compartment 10 , it is helpful to improve the uniformity of the magnetic field of the storage compartment 10 .

[0060] It should be noted that in some other embodiments, the two static magnetic field devices may be respectively arranged on the left and right sides of the storage room. In addition, in the case where no storage container is provided, two electromagnetic coils may be provided, and the two electromagnetic coils may be both located inside the storage room, or both located outside the storage room, or one may be inside the storage room and the other outside the storage room.
