The number and function of the specific storage compartments can be configured according to pre-determined requirements.
The refrigerator 10 of the present embodiment may be an air-cooled refrigerator, in which an air path system is disposed in the cabinet 120, and a fan sends a cooling air flow, which is heat-exchanged by a heat exchanger (evaporator), to the storage compartment through the air supply opening, and then returns to the air duct through the air return opening.

The number of the magnetic field freshness retaining storage containers 200 and the storage compartments arranged therein may be configured according to the user's needs. For example, one or more magnetic field fresh food containers 200 may be disposed within the refrigerator 10. The magnetic field freshness retaining storage container 200 may be disposed in a cold storage compartment, or a temperature-changing storage compartment, and may be used for magnetic field-assisted freshness retaining in the storage compartments, or may be used as an independent compartment of the refrigerator 10.

The magnetic freshness storage container 200 may generally comprise: a storage assembly 210, one or more magnetic field assemblies 201. Wherein the storage assembly 210 defines a storage space therein for placing stored objects, and the storage assembly may be box-shaped. In some embodiments, the storage assemblies may be generally flat and rectangular in shape (i.e., the distance in the height direction is significantly less than the distance in the depth direction and the distance in the lateral left-right direction). The storage assembly 210 may be a drawer structure, that is, the storage assembly may include: a cylinder and a drawer. Wherein the barrel has a forward opening. The drawer is arranged in the cylinder in a drawing way. The drawer can be pulled out to expose the storage space so as to take and place the stored objects. After the drawer is pushed into the cylinder, an independent sealed space can be formed. The construction of the drawer itself for a refrigerator is well known to those skilled in the art and will not be described herein.
Each magnetic field assembly 201 may include: one or more magnetic elements 220 and an annular magnetically permeable member 230. The magnetic member 220 is disposed at an outer side of the storage assembly for forming a magnetic field in the storage space. The magnetic member may be a permanent magnetic member or an electromagnetic member, and in some alternative embodiments, the magnetic member 220 may include both a permanent magnetic member and an electromagnetic member, the permanent magnetic member is used to provide a basic permanent magnetic field, and the electromagnetic member is energized to form an electromagnetic field superposed with the permanent magnetic field. The intensity range of the magnetic field can be set to be 1Gs-100Gs, and in the case of being applied to a freezing environment, the magnetic field intensity range can be preferably 5-60 GS, for example, about 20Gs can be selected; in the case of application to a refrigeration environment, the magnetic field intensity can be 20-160 GS, preferably 40-80 Gs, such as about 60 Gs.
The annular magnetic conduction member 230 includes a uniform magnetic plate 231 disposed corresponding to the magnetic member 220 and a connection band 232 connected to the uniform magnetic plate 231 and disposed around the periphery of the storage module 210, and the uniform magnetic plate 231 and the connection band 232 form an annular magnetic conduction path outside the storage space. The annular magnetic conductive member 230 may be made of a material with low coercive force and high magnetic permeability, and the formed magnetic conductive path may be used to gather the magnetic field, improve the uniformity of the magnetic field in the storage space, and at the same time, reduce the release of the magnetic field to the outside, and reduce the interference with other components outside the storage assembly 210 (e.g., avoid magnetizing other components, etc.). The annular magnetically permeable member 230 may be made of a sheet of silicon steel or the like.
The annular magnetically permeable member 230 may be integrally formed as a single piece, i.e. the shim plate 231 and the connecting band 232. In other embodiments, the shim plate 231 and the connecting band 232 can also be spliced to form the annular magnetic conductive member 230.
The uniform magnetic plate 231 is disposed corresponding to the magnetic member 220, and can more uniformly release the magnetic field generated by the magnetic member 220 into the storage space.
The magnetic member 220 may include an electromagnetic ring 221, inside which an electromagnetic coil is wound along a circumferential direction, and the electromagnetic coil is energized to form an electromagnetic field in the storage space.
The electromagnetic coil 221 may be wound by an electromagnetic coil and has a circular, oval or square shape. The electromagnetic coil may be flat, with the top and bottom planar, and with a thickness significantly less than the peripheral dimension. The width-to-thickness ratio of the electromagnetic coil 221 may be set to a range of 1-10.
In some embodiments, the shim plate 231 may be disposed at the central through hole of the electromagnetic ring 221, and the shape of the shim plate 231 is matched with the shape of the central through hole, so that the magnetic field assembly 201 occupies a smaller space, and the magnetic fresh-keeping storage container 200 is more compact.
In other embodiments, the shim plate 231 may be disposed against the electromagnetic coil 221. The shim plate 231 may have a size larger than the outer peripheral size of the electromagnetic ring 221, and the electromagnetic ring 221 is disposed concentrically with the shim plate 231. Thereby enlarging the range of the magnetic field using the shim plate 231.
Each magnetic field assembly 201 includes two magnetic elements 220. The two magnetic members 220 are respectively disposed on a set of opposite side surfaces of the storage assembly 210, and the annular magnetic conductive member 230 is respectively disposed with a uniform magnetic plate 231 at corresponding positions of the two magnetic members 220. The position of the magnetic member 220 may be set according to the configuration of the side on which it is located. In general, the magnetic members 220 may be opposite to the center of the respective sides. For example, the magnetic members 220 may be selectively placed on the lateral sides, the top and bottom sides, or the front and rear sides of the storage assembly 210. The magnetic pole directions of the magnetic member 220 are all towards the storage space, so that the magnetic field penetrates through the storage space.
In the case where the storage module 210 has a shape of a whole flat rectangular parallelepiped (i.e., the distance in the height direction is significantly smaller than the distance in the depth direction and the distance in the lateral left-right direction), the magnetic members 220 may be preferentially arranged to be disposed at both sides of the top and bottom of the storage module 210. That is, the storage assembly 210 is flat, and the two magnetic members 220 of the magnetic field assembly 201 are respectively disposed at the top and the bottom of the storage assembly 210. The magnetic field penetrates through the storage space from top to bottom or from bottom to top. With such an arrangement, the distance between the two magnetic members 220 can be reduced, and the strength and uniformity of the magnetic field can be improved.
The magnetic members 220 on both sides may have substantially the same configuration and size, ensuring uniformity of the magnetic field. The magnetic field of the magnetic member 220 is required to ensure that a uniform magnetic field is formed at all positions of the storage space. That is, the storage space is positioned in the magnetic field range without dead angles.
The projection of the storage space on the plane of the magnetism homogenizing plate 231 is located in the range of the magnetism homogenizing plate 231, and the size of the magnetic member 220 can be smaller than or equal to the size of the magnetism homogenizing plate 231 opposite to the magnetic member. That is, the level-distribution plate 231 may be equal to or slightly larger than the corresponding side of the storage module 210. Under the condition that the magnetic members 220 are arranged at the top and the bottom of the storage assembly, the even magnetic plates 231 arranged corresponding to the top magnetic members 220 can respectively cover the top surface of the storage space; the magnetism equalizing plates 231 provided corresponding to the bottom magnetic member 220 may cover the bottom surfaces of the storage spaces, respectively.
The shimming plate 231 can enlarge the coverage of the magnetic field and make the magnetic field more uniform. The connection strap 232 may include two segments, and each segment of the connection strap 232 extends from the edge of the magnetic uniforming plate 231 on one side to the edge of the magnetic uniforming plate 231 on the other side along the outer wall of the storage module 210. In cross section, the shim plate 231 and the connecting strap 232 form a ring around the periphery of the storage module 210.
In the embodiment where the magnetic members 220 are respectively disposed on the top wall and the bottom wall of the storage module 210, a length of the connecting strap 232 extends from the middle of one lateral side (e.g., right side) of the top shim plate 231 to the middle of the corresponding side (e.g., right side) of the bottom shim plate 231 along one lateral side wall of the storage space; another connecting band 232 extends from the middle of the other lateral side (e.g., left side) of the top shim plate 231 to the middle of the other lateral side (e.g., left side) of the bottom shim plate 231 along the other lateral sidewall of the storage space.
The connecting band 232 may be a strip shape, and the width of the connecting band in the front-rear depth direction is one half to one tenth of the length of the uniform magnetic plate 231 in the front-rear depth direction. That is, the connection belt 232 may be disposed at the middle position of the front-back direction of the shim plate 231 and is significantly narrower than the shim plate 231. The structure of the annular magnetic conduction member 230 can reduce the use of magnetic conduction materials and magnetic components under the condition of meeting the requirement of magnetic field intensity, save the cost of the magnetic field fresh-keeping storage container 200, and reduce the weight of the magnetic field fresh-keeping storage container 200 and the whole refrigerator 10.
In the embodiment shown in fig. 2 to 4, there is one magnetic field assembly 201, and the two magnetic members 220 of the magnetic field assembly 201 have shapes respectively corresponding to the shapes of the side surfaces of the storage assemblies 210 arranged therein. For example, the top magnetic member 220 may conform to the shape of the top surface of the storage assembly 210 and the bottom magnetic member 220 may conform to the shape of the bottom surface of the storage assembly 210. A top shim plate 231 is disposed above the top magnetic member 220, and a bottom shim plate 231 is disposed below the bottom magnetic member 220. The top uniform magnetic plate 231 covers the top surface of the storage space; the bottom magnetism equalizing plates 231 may cover the bottom surfaces of the storage spaces, respectively. A longitudinal magnetic field without dead angles is formed in the storage space. The connecting band 232 is located at the center of the front-back depth direction of the magnetic field assembly 201, so that a magnetic conduction path is formed outside the storage space, and the magnetic field is prevented from leaking outwards.
The magnetic field directions of the two magnetic members 220 are set to be the same, so that a uniform magnetic field is formed in the storage space. That is, the N poles of the two magnetic members 220 face the same direction, and the S poles face opposite directions. The direction of the magnetic field in the storage space can be from top to bottom or from bottom to top. The magnetic field direction shown in fig. 4 is from bottom to top, and based on the same technical idea, it is easy for those skilled in the art to realize a magnetic field in the opposite direction by adjusting the magnetic pole direction, that is, to realize a magnetic field from top to bottom.
Based on the above description of the embodiment in which the magnetic member 220 and the magnetism equalizing plate 231 are respectively disposed at the top and the bottom, those skilled in the art can easily implement the solution in which the magnetic member 220 and the magnetism equalizing plate 231 are respectively disposed at the left and right side walls and the front and rear side walls. Considering that the electromagnetic ring 221 generates heat during the process of generating the magnetic field by electrifying, the distance between the magnetic member and the stored object in the storage space may be set to be not less than 1 mm.
FIG. 5 is a schematic view of a magnetic field freshness storage container 200 according to another embodiment of the present invention; fig. 6 is a schematic view of the arrangement of the electromagnetic coil 221 in the magnetic field freshness storage container 200 shown in fig. 5. In this embodiment, the magnetic field assemblies 201 are arranged at intervals along the depth direction or the height direction of the storage assembly 210. Each magnetic field assembly 201 again has two magnetic elements 220. The two magnetic members 220 are respectively disposed on a set of opposite side surfaces of the storage assembly 210, and the annular magnetic conductive member 230 is respectively disposed with a uniform magnetic plate 231 at corresponding positions of the two magnetic members 220.
For the structure that the magnetic field assemblies 201 are arranged at intervals along the depth direction of the storage assembly 210, the magnetic members 220 can be selectively placed on the two lateral sides or the top and bottom sides of the storage assembly 210. A plurality of magnetic field components 201 form a set of magnetic field respectively, and the magnetic field of a plurality of magnetic field components 201 superposes each other, can make the magnetic field in the storing space more even.
For the structure that the magnetic field assemblies 201 are arranged at intervals along the height direction of the storage assembly 210, the magnetic members 220 can be selectively placed on both lateral sides or both front and rear sides of the storage assembly 210.
The magnetic member 220 may also use an electromagnetic coil 221. The electromagnetic coil 221 is wound with an electromagnetic coil along the circumferential direction, and the electromagnetic coil forms an electromagnetic field in the storage space after being electrified.
