[0048] Furthermore, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] like Figure 1 As shown, in one embodiment, the refrigerator includes a box body 1 and a drawer assembly 2. A storage compartment is formed in the box body 1. The drawer assembly 2 is arranged in the storage compartment. The refrigerator usually has multiple storage compartments for achieving different functions. For example, a refrigerated storage compartment 11, a frozen storage compartment, a variable temperature storage compartment, etc. The number and function of the specific storage compartments can be configured according to pre-determined requirements. Figure 1 The refrigerator shown has three storage compartments arranged vertically is only an example, and those skilled in the art can configure the specific number, function and layout of the storage compartments according to needs.

[0050] One or more drawer assemblies may be arranged in the refrigerator of this embodiment. In some optional embodiments, the drawer assembly may be arranged in one or more of the above-mentioned multiple storage compartments, and through magnetic field and temperature control, long-term high-quality cold and fresh preservation of food materials such as meat and fish can be achieved. For example, the drawer assembly may be arranged in any one of the refrigerated storage compartment, the frozen storage compartment, and the variable temperature storage compartment. For another example, the drawer assembly may also be arranged in multiple refrigerated storage compartments, the frozen storage compartment, and the variable temperature storage compartment at the same time, that is, drawer assemblies are respectively arranged in multiple different storage compartments at the same time. For another example, multiple drawer assemblies may also be arranged in a storage compartment at the same time as needed.

[0051] like Figures 2 to 4 As shown, in one embodiment, the drawer assembly includes a drawer 100, a first magnetic field assembly 200 and a second magnetic field assembly 300. The drawer 100 is formed with a storage space 101. The first magnetic field assembly 200 and the second magnetic field assembly 300 are arranged in the storage space 101 to generate a magnetic field in the storage space 101. In the same transverse plane, the areas surrounded by the envelopes of the projections of the first magnetic field assembly 200 and the second magnetic field assembly 300 intersect with each other to form an overlapping area.

[0052] Specifically, the first magnetic field assembly 200 includes two magnetic field devices 210, and the two magnetic field devices 210 can generate magnetic fields respectively. The two magnetic field devices 210 are respectively located on both sides of the overlapping area. The second magnetic field assembly 300 includes two magnetic field devices 310, and the two magnetic field devices 310 can generate magnetic fields respectively. The two magnetic field devices 310 are respectively located on both sides of the overlapping area. The two magnetic field devices 210 are distributed in the storage space 101 along the front and back direction of the drawer 100, that is, the first magnetic field assembly 200 extends in the front and back direction of the drawer 100. The two magnetic field devices 310 are distributed in the storage space 101 along the left and right direction of the drawer 100, that is, the second magnetic field assembly 300 extends in the left and right direction of the drawer 100.

[0053] Combination Figure 5As shown, the four shaded areas in the figure are the projections of the two magnetic field devices 210 and the two magnetic field devices 310 in the same transverse plane, that is, the projections of the first magnetic field assembly 200 and the second magnetic field assembly 300. Among them, the area surrounded by the envelope of the first magnetic field assembly 200 is the plane area that completely covers the projection of the first magnetic field assembly 200 and has the highest overlap with the edge line of the projection of the first magnetic field assembly 200. Specifically, the projection of the first magnetic field assembly 200 is the projection of two rectangles, and the area surrounded by the envelope of the first magnetic field assembly 200 is the projection of a large rectangle that completely covers the two projections. The area surrounded by the envelope of the second magnetic field assembly 300 is the plane area that completely covers the projection of the second magnetic field assembly 300 and has the highest overlap with the edge line of the projection of the second magnetic field assembly 300. Specifically, the projection of the second magnetic field assembly 300 is the projection of two rectangles, and the area surrounded by the envelope of the second magnetic field assembly 300 is the projection of a large rectangle that completely covers the two projections. The overlapping area formed by the intersection of the areas surrounded by the envelopes of the projections of the first magnetic field assembly 200 and the second magnetic field assembly 300 is a square area where the two large rectangular projections overlap. Preferably, the center of the overlapping area coincides with the center of the projection of the storage space 101 on the same horizontal plane.

[0054] like Figure 4 and Figure 5 As shown, further, along the direction surrounding the overlap region, the magnetic poles of the adjacent surfaces of the first magnetic field assembly 200 and the second magnetic field assembly 300 are opposite. Specifically, Figure 5 The direction of the arrow in indicates the direction surrounding the overlap region. That is, along the direction surrounding the overlap region, the magnetic poles of the adjacent faces of the magnetic field device 210 and the adjacent magnetic field device 310 are opposite, so for all adjacent faces of the first magnetic field component 200 and the second magnetic field component 300 along the direction surrounding the overlap region, the magnetic field lines are directed from the first magnetic field component 200 to the second magnetic field component 300, or from the second magnetic field component 300 to the first magnetic field component 200, in the same direction surrounding the overlap region, Figure 4 The arrow lines in FIG. 1 are schematic diagrams of magnetic field lines, so that the magnetic field lines formed by the two magnetic field components are roughly in a ring shape.

[0055] In the scheme of the present embodiment, by arranging the first magnetic field component 200 and the second magnetic field component 300 in the storage space 101 of the drawer 100, the areas surrounded by the envelope lines of the projections of the first magnetic field component 200 and the second magnetic field component 300 in the same transverse plane intersect with each other to form an overlapping area, that is, a part of the first magnetic field component 200 is located on both sides of the second magnetic field component 300, and a part of the second magnetic field component 300 is also located on both sides of the first magnetic field component 200, so that the first magnetic field component 200 and the second magnetic field component 200 are structures that intersect with each other as a whole, so that the first magnetic field component 200 and the second magnetic field component 300 can be regarded as roughly dividing the storage space 101 into four small areas, and generating the same magnetic field in each small area, thereby ensuring that the magnetic field in each area is roughly the same, so that the magnetic field of the storage space 101 as a whole is more uniform, which is conducive to ensuring that the food placed in different areas has the same preservation effect.

[0056] Moreover, the first magnetic field component 200 and the second magnetic field component 300 are arranged in the storage space 101, and guide their respective magnetic fields to each other in the storage space 101. The magnetic field diverges from the storage space 101 to the surroundings, which helps to concentrate the magnetic field in the storage space 101 and improve the utilization rate of the magnetic field.

[0057] Furthermore, by making the magnetic poles of the adjacent surfaces of the first magnetic field assembly 200 and the second magnetic field assembly 300 in the direction surrounding the overlapping area opposite, the first magnetic field assembly 200 and the second magnetic field assembly 300 can jointly generate a substantially annularly distributed magnetic field line in the storage space 101, thereby making the magnetic field intensity in the entire storage space 101 more uniform, and more conducive to concentrating the magnetic field in the storage space 101.

[0058] It should be noted that in some other embodiments, along the direction surrounding the overlap region, the magnetic poles of the adjacent surfaces of the first magnetic field component and the second magnetic field component are the same. Regardless of being the same or opposite, the magnetic pole distribution of the portion of the first magnetic field component located on both sides of the overlap region is opposite, and the magnetic field distribution of the portion of the second magnetic field component located on both sides of the overlap region is opposite.

[0059] like Figures 2 to 6 As shown, further, the drawer assembly includes a support structure 400, the support structure 400 is arranged in the storage space 101, and the first magnetic field assembly 200 and the second magnetic field assembly 300 are fixed in the storage space 101 via the support structure 400. Specifically, the support structure 400 is a cross-shaped bracket structure, that is, the support structure 400 can be regarded as two plate-like structures crossed, one plate-like structure is used to install the first magnetic field assembly 200, and the other plate-like structure is used to install the second magnetic field assembly 300.

[0060] Combination Figures 2 to 6As shown, the support structure 400 is provided with a mounting groove 401, and the first magnetic field assembly 200 and the second magnetic field assembly 300 are fixed in the mounting groove 401. Specifically, the thickness of the support structure 400 is greater than the thickness of the first magnetic field assembly 200 and the second magnetic field assembly 300, so that the support structure 400 can form a mounting groove 401 sufficient to accommodate the magnetic field assembly.

[0061] Reference Figures 2 to 4 As shown, further, the cross-shaped support structure 400 divides the storage space 101 into four storage areas, and two side walls of each storage area are provided with magnetic field components.

[0062] like Figures 2 to 4 As shown, the drawer assembly includes a mounting structure, and the support structure 400 is detachably fixed in the storage space 101 via the mounting structure. The mounting structure includes four limiting grooves 500, which are respectively arranged on the four inner side walls of the drawer 100, and the four side portions of the support structure 400 are respectively embedded in the limiting grooves 500. Specifically, the limiting grooves 500 extend in the longitudinal direction, and after aligning the four side portions of the support structure 400 with the four limiting grooves 500, the support structure 400 is inserted into the limiting grooves 500 from top to bottom, so that the support structure 400 can be fixed in the storage space 101.

[0063] By arranging the support structure 400 in the storage space 101, the first magnetic field assembly 200 and the second magnetic field assembly 300 can be fixed in the storage space 101 via the support structure 400, which is conducive to improving the fixing effect of the first magnetic field assembly 200 and the second magnetic field assembly 300. By arranging the mounting groove 401 on the support structure 400, the first magnetic field assembly 200 and the second magnetic field assembly 300 can be installed in the mounting groove 401, thereby protecting the magnetic field assembly. Further, by arranging the limiting groove 500 on the side wall of the drawer 100, the support structure 400 can be clamped and fixed in the limiting groove 500, thereby fixing the support structure 400 in the storage space 101. During use, along the extension direction of the limiting groove 500, that is, along the longitudinal direction, the support structure 400 is moved, and the support structure 400 can be placed in the limiting groove 500 or taken out of the limiting groove 500, thereby realizing the disassembly and assembly of the support structure 400 and the drawer 100, making the assembly of the support structure 400 simpler.

[0064] It should be noted that in some other embodiments, one, two or three limiting grooves may be provided.

[0065] It should be noted that, in some other embodiments, the support structure may also be integrally formed with the drawer. In this case, the support structure may also be a clamping groove provided on the drawer to directly clamp the magnetic field assembly.

[0066] It should be noted that in some other embodiments, the support structure may not be provided, and the magnetic field component may be directly adhered to the storage space of the drawer.

[0067] like Figures 2 to 7 As shown, further, an elastic buckle 410 is provided at a position of the mounting groove 401 near the top of the support structure 400, and the elastic buckle 410 forms a stop for the magnetic field component installed in the mounting groove 401 in the longitudinal direction, that is, forms a stop for the magnetic field device. Specifically, each mounting groove 401 is provided with two elastic buckles 410, and the two elastic buckles 410 are respectively located on two opposite side walls of the mounting groove 401, one end of the elastic buckle 410 is fixed to the side wall of the mounting groove 401, and the other end is movable. In the initial state, the distance between the movable ends of the two elastic buckles 410 is smaller than the size of the magnetic field device in the corresponding direction. In the process of the magnetic field device being embedded in the mounting groove 401, the magnetic field device contacts the movable end of the elastic buckle 410, and as the magnetic field device continues to be embedded in the mounting groove 401, the magnetic field device squeezes the elastic buckle 410 to deform the elastic buckle 410, thereby increasing the distance between the elastic buckles 410, so that the magnetic field device can cross the elastic buckle 410 and be embedded in the mounting groove 401. After the magnetic field device is installed in place, the movable end of the elastic clip 410 returns to its original position under the action of its own elastic force, that is, returns to the position where the distance between the movable ends of the elastic clip 410 is smaller than the dimension of the magnetic field device in the corresponding direction, thereby forming a stop for the magnetic field device in the longitudinal direction.

[0068] By setting an elastic buckle 410 in the installation groove 401, the elastic buckle 410 can form a stop for the magnetic field component in the installation groove 401 in the longitudinal direction, thereby preventing the magnetic field component from falling out of the installation groove 401 and avoiding the magnetic field component from falling out of the installation groove 401 and being damaged by impact.

[0069] It should be noted that, in some other embodiments, the magnetic field assembly may be fixed in the mounting groove by adhesive fixation or interference fit. In addition, in some other embodiments, the support structure may also be a thin plate-like structure, and the magnetic field assembly is directly arranged on the surface of the plate.

[0070] Reference Figure 3 As shown, specifically, the magnetic field device 210 or the magnetic field device 310 only includes a magnetic field generating component, which is a permanent magnet sheet. In other words, the magnetic field device 210 and the magnetic field device 310 are a permanent magnet sheet, which has a simple structure and can achieve good cooperation with the support structure 400 without additional structure.

[0071] It should be noted that, in some other embodiments, the magnetic field generating element may also be an electromagnetic coil.

[0072] like Figures 2 to 8As shown, the ratio of the dimension of the portion of the second magnetic field component 300 located on one side of the first magnetic field component 200 along the left-right direction to the distance between the side wall of the drawer 100 located on the same side of the first magnetic field component 200 and the first magnetic field component 200 is greater than or equal to 0.6 and less than or equal to 1, and the ratio of the dimension of the portion of the first magnetic field component 200 located on one side of the second magnetic field component 300 along the front-to-back direction to the distance between the side wall of the drawer 100 located on the first magnetic field component 200 and the first magnetic field component 200 is greater than or equal to 1.

[0073] Reference Figure 8 As shown, taking the portion of the second magnetic field assembly 300 located on the left side of the first magnetic field assembly 200 as an example, that is, the magnetic field device 310 located on the left side of the first magnetic field assembly 200, the size of the magnetic field device 310 along the left-right direction is a, and the distance between the side wall of the drawer 100 located on the left side of the first magnetic field assembly 200, that is, the left side wall and the first magnetic field assembly 200 is W, and a / W is greater than or equal to 0.6 and less than or equal to 1, for example, it can be 0.6, 0.7, 0.8, 0.9, 1, etc. The size of the portion of the first magnetic field assembly 200 located on one side of the second magnetic field assembly 300, that is, a magnetic field device 210 along the front-to-back direction is b, and b / W is greater than or equal to 1, for example, it can be 1, 1.1, 1.2, etc., and the proportional relationship can be set according to the specific size of the drawer 100.

[0074] The above structure is advantageous in that the magnetic field generated by the magnetic field assembly has a better coverage of the corresponding storage area, so as to ensure that the magnetic field generated by the magnetic field assembly can also generate sufficient magnetic field strength at the diagonal of the storage space 101.

[0075] It should be noted that, in some other embodiments, the ratio of the dimension of the portion of the first magnetic field component located on one side of the second magnetic field component along the front-to-back direction to the distance between the side wall of the drawer located on the same side of the second magnetic field component and the second magnetic field component may be greater than or equal to 0.6 and less than or equal to 1, and the ratio of the dimension of the portion of the second magnetic field component located on one side of the first magnetic field component along the left-to-right direction to the distance between the side wall of the drawer located on the second magnetic field component and the second magnetic field component may be greater than or equal to 1.

[0076] It should be noted that the size of the magnetic field assembly involved in the above-mentioned structural relationship is the size of the component of the magnetic field assembly that actually generates the magnetic field.

[0077] like Fig. 9As shown, in another embodiment, the mounting structure includes a mounting hole (not marked in the figure) and a fixing nail 600. The mounting hole is provided on the side wall of the drawer 100 and the side of the support structure 400. The fixing nail 600 passes through the mounting holes provided on the side wall of the drawer 100 and the support structure 400 to detachably fix the support structure 400 and the drawer 100 together. Specifically, the mounting structure includes four fixing nails 600, which are respectively used to fix the front side wall, the rear side wall, the left side wall, the right side wall and the support structure 400 of the drawer 100. The fixing nail 600 passes through the side wall of the drawer 100 and is embedded in the support structure 400, thereby achieving the fixation of the drawer 100 and the support structure 400.

[0078] By adopting the mounting structure composed of the mounting holes and the fixing nails 600 , the support structure 400 and the drawer 100 can also be detachably mounted, thereby facilitating the replacement of the support structure 400 .

[0079] like Fig.10 and Fig.11 As shown, in another embodiment, the magnetic field device includes two magnetic field generating elements and a magnetic conductive plate. In the direction surrounding the overlapped area, the two magnetic field generating elements are respectively arranged on both sides of the magnetic conductive plate, and the magnetic pole distribution of the two magnetic field generating elements is the same. Taking a magnetic field device 210 as an example, specifically, the magnetic field device 210 includes a magnetic conductive plate 211, a magnetic field generating element 212, and a magnetic field generating element 213. The magnetic field generating element 212 and the magnetic field generating element 213 are respectively arranged on both sides of the magnetic conductive plate 211. It can also be said that the magnetic field generating element 212 and the magnetic field generating element 213 sandwich the magnetic conductive plate 211 in the middle. The magnetic poles of the magnetic field generating element 212 and the magnetic field generating element 213 facing the magnetic conductive plate 211 are opposite, that is, the magnetic poles of the magnetic field generating element 212 and the magnetic field generating element 213 facing away from the magnetic conductive plate 211 are opposite, so that the magnetic poles of the two sides of the entire magnetic field device 210 are different.

[0080] By configuring the magnetic field device to be a structure consisting of a magnetic conductive plate and two magnetic field generating components, and locating the two magnetic field generating components on both sides of the magnetic conductive plate, the magnetic field strength of the magnetic field assembly is enhanced, and the magnetic conductive plate can guide the magnetic field generated by the magnetic field generating components, thereby further improving the uniformity of the magnetic field in the storage space.

[0081] It should be noted that, in some other embodiments, the magnetic field generating element may be a permanent magnet sheet or an electromagnetic coil.

[0082] like Fig.10 and Fig.11As shown, further, the distance between the edge of the magnetic field generating member and the edge of the magnetic conductive plate is greater than or equal to 3 mm. Exemplarily, the magnetic field generating member 213 is a square permanent magnetic sheet, which is arranged on one side of the square magnetic conductive plate 211. The distance between the edge of the magnetic field generating member 213 and the edge of the magnetic conductive plate 211 is the distance between the square side edge of the magnetic field generating member 213 and the square side edge of the magnetic conductive plate 211. Fig.12 As shown, taking the magnetic field device 210 as an example, the distance between the edge of the magnetic field generating element and the edge of the magnetic conductive plate is X, and X is greater than or equal to 3 mm, for example, it can be 3 mm, 4 mm, etc. Preferably, it is less than or equal to 10 mm. This helps to ensure the guiding effect of the magnetic conductive plate on the magnetic field generating element.

[0083] like Fig.12 As shown, in another embodiment, the second magnetic field assembly 300 includes an integrally formed magnetic field generating device. The integrally formed magnetic field generating device has parts located on both sides of the overlapping area. Specifically, the second magnetic field assembly 300 is a whole integrally formed magnetic sheet, and the magnetic sheet is magnetized in sections so that the magnetic poles of the two parts are different, which simplifies the installation of the magnetic field assembly on the basis of achieving a uniform magnetic field in the storage space.

[0084] It should be noted that, in some other embodiments, the first magnetic field assembly may include an integrally formed magnetic field generating device. Alternatively, both the first magnetic field assembly and the second magnetic field assembly may include an integrally formed magnetic field generating device. In addition, under the condition that the first magnetic field assembly or the second magnetic field assembly includes an integrally formed magnetic field generating device, an integrally formed magnetic conductive plate may also be included.

[0085] like Fig.13 and Fig.14 As shown, in another embodiment, the drawer assembly further includes four shimming plates 700, which are respectively arranged on the four side walls of the drawer 100, and two adjacent shimming plates 700 are connected. Specifically, a shimming plate 700 is respectively arranged on the outer side of the rear side wall, the outer side of the left side wall, and the outer side of the right side wall of the drawer 100. A shimming plate 700 is arranged on the inner side of the front side wall of the drawer 100. The shimming plate 700 arranged on the front side wall of the drawer 100 passes through the left side wall of the drawer 100 and is connected to the shimming plate 700 arranged on the left side wall of the drawer 100, and passes through the right side wall of the drawer 100 and is connected to the shimming plate 700 arranged on the right side wall of the drawer 100. The shimming plate 700 arranged on the rear side wall of the drawer 100 is connected to the shimming plate 700 arranged on the left side wall of the drawer 100 on the outside of the drawer 100, and is connected to the shimming plate 700 arranged on the right side wall of the drawer 100 on the outside of the drawer 100.

[0086] By respectively arranging the magnetic shimming plates 700 on the four side walls of the drawer 100, two adjacent magnetic shimming plates 700 are connected, that is, the four magnetic shimming plates 700 surround the storage space 101. Fig.14 As shown by the magnetic field lines indicated by arrow lines in the figure, the uniform magnetic plate 700 can converge the magnetic field generated by the first magnetic field component 200 and the second magnetic field component 300 as much as possible in the storage space 101, thereby further improving the uniformity of the magnetic field in the storage space 101 and improving the utilization rate of the magnetic field.

[0087] Reference Fig.13 and Fig.14 As shown, the first magnetic field assembly 200 extends along the front-to-back direction of the drawer 100, and the second magnetic field assembly 300 extends along the left-to-right direction of the drawer 100. The distance between the front and rear sides of the first magnetic field assembly 200 and the closest shimming plate 700 is greater than or equal to 2 mm, and the distance between the left and right sides of the second magnetic field assembly 300 and the closest shimming plate 700 is greater than or equal to 2 mm. In other words, the distance between the front side of the first magnetic field assembly 200 and the shimming plate 700 disposed on the front side wall of the drawer 100 is greater than or equal to 2 mm, the distance between the rear side of the first magnetic field assembly 200 and the shimming plate 700 disposed on the rear side wall of the drawer 100 is greater than or equal to 2 mm, the distance between the left side of the second magnetic field assembly 300 and the shimming plate 700 disposed on the left side wall of the drawer 100 is greater than or equal to 2 mm, and the distance between the right side of the second magnetic field assembly 300 and the shimming plate 700 disposed on the right side wall of the drawer 100 is greater than or equal to 2 mm. Taking the first magnetic field component 200 as an example, the distance between the rear side of the first magnetic field component 200 and the uniform magnetic plate 700 arranged on the rear wall of the drawer 100 is d, and d is greater than or equal to 2 mm. For example, it can be 2 mm, 3 mm, etc. Preferably, it is less than or equal to 20 mm. The above-mentioned structure helps to ensure the convergence effect of the uniform magnetic plate 700 on the magnetic field component. It should be noted that the distance between the magnetic field component and the uniform magnetic plate involved in the above-mentioned structural relationship is the distance between the component of the magnetic field component that actually generates the magnetic field and the uniform magnetic plate.
