[0044] It should be understood by those skilled in the art that the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention, and the embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention.

[0046] 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 direct connection, an indirect connection through an intermediate medium, or 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.

[0047] like Figure 1 As shown, in one embodiment, the refrigerator 10 includes a box body 100 and a magnetic field preservation container 200 in any of the following embodiments. A cold storage compartment 101 is formed in the box body 100. The magnetic field preservation container 200 is arranged in the cold storage compartment 101.

[0048] It should be noted that a refrigerator usually has multiple cold storage compartments for achieving different functions, such as a refrigeration compartment, a freezer compartment, a variable temperature compartment, etc. The specific number and function of the cold storage compartments can be configured according to pre-determined requirements. The magnetic field preservation container can be set in any cold storage compartment. Figure 1 The refrigerator shown is only an example, and those skilled in the art can configure the specific number, function and layout of the cold storage compartments according to needs.

[0049] In addition, the refrigerator of this embodiment is an air-cooled refrigerator. A refrigeration space and an air duct system are provided in the box body, and a fan and a heat exchanger (evaporator) are provided in the refrigeration space. The fan is used to send the cold air that has been heat-exchanged by the heat exchanger to the cold storage compartment through the box body air supply port, and then return to the refrigeration space through the box body return air port, so as to realize circulating air refrigeration. Since the box body, door body, and refrigeration system of this type of refrigerator are well known to those skilled in the art and are easy to implement, in order not to cover up and obscure the utility model points of this application, the box body, door body, and refrigeration system themselves will not be described in detail below.

[0050] like Figures 2 to 6 As shown, in one embodiment, the magnetic field preservation container 200 includes a barrel body 210, a drawer 220, a top insulation layer 230, a side insulation layer 240, a rear insulation layer 250 and a magnetic field generating module 260.

[0051] like Figure 2 and Figure 3 As shown, the barrel body 210 is formed with a magnetic fresh-keeping space 201 with a front opening. The drawer 220 is arranged in the magnetic fresh-keeping space 201 in a pullable manner, and the drawer 220 is used to store the stored objects. In other words, the drawer 220 can be pulled out from the magnetic fresh-keeping space 201 or put into the magnetic fresh-keeping space 201 through the front opening of the magnetic fresh-keeping space 201. When the drawer 220 is put into the magnetic fresh-keeping space 201, the front panel of the drawer 220 covers and seals the front opening of the barrel body 210.

[0052] like Figures 2 to 4 As shown, the barrel 210 is formed with two compartments distributed on the left and right and open at the front end, one of which is a magnetic fresh-keeping space 201, and the other is a common refrigeration compartment 202. Specifically, the left compartment is the magnetic fresh-keeping space 201, and the right compartment is the common refrigeration compartment 202. The common refrigeration compartment 202 is connected to the cold storage compartment 101 of the refrigerator 10, that is, it achieves the same refrigeration effect as other areas of the cold storage compartment 101.

[0053] And refer to Figures 2 to 5 As shown, the magnetic fresh-keeping space 201 is used to store food in a magnetic field and has a separate temperature requirement, so it is cooled separately and insulated from the outside. Specifically, for the separate refrigeration of the magnetic fresh-keeping space 201, the magnetic field fresh-keeping container 200 is formed with a cold air circuit for refrigerating the magnetic fresh-keeping space 201, and the cold air circuit is connected to the air supply port and the return air port of the refrigerator body, so that the cold air generated by the refrigerator refrigeration space can enter the cold air circuit, and return to the refrigeration space after flowing through the cold air circuit, completing the circulation refrigeration of the magnetic fresh-keeping space 201.

[0054] Continue to refer to Figures 2 to 5 As shown, for the insulation structure of the magnetic fresh-keeping space 201, first, a thermal insulation layer is provided between the magnetic fresh-keeping space 201 and the ordinary refrigeration compartment 202 to achieve thermal insulation between the magnetic fresh-keeping space 201 and the ordinary refrigeration compartment 202. In other words, the magnetic fresh-keeping space 201 and the ordinary refrigeration compartment 202 share a side wall with thermal insulation (constituting the right side wall of the magnetic fresh-keeping space 201). In addition, the top thermal insulation layer 230 is arranged on the outside of the top wall of the magnetic fresh-keeping space 201, the side thermal insulation layer 240 is arranged on the outside of the left side wall of the magnetic fresh-keeping space 201, and the rear thermal insulation layer 250 is arranged on the outside of the rear side wall of the magnetic fresh-keeping space 201, thereby achieving thermal insulation between the magnetic fresh-keeping space 201 and the cold storage compartment 101.

[0055] It should be noted that the outer side of the bottom side wall of the magnetic fresh-keeping space is also provided with a bottom insulation layer. However, in some other embodiments, because the bottom side wall of the barrel body can fit the box body wall well, the bottom insulation layer may not be provided.

[0056] In addition, it should be noted that in some other embodiments, the magnetic field preservation container may also have only one magnetic preservation space, both side walls may be provided with insulation layers, or one side wall may be in contact with the box wall, so that the insulation layer is only provided on one side wall.

[0057] like Figures 2 to 6As shown, the magnetic field preservation container 200 includes two magnetic field generating modules 260, and the two magnetic field generating modules 260 are respectively arranged on opposite sides of the magnetic preservation space 201 to generate a magnetic field inside the magnetic preservation space 201. Specifically, the two magnetic field generating modules 260 are respectively arranged on the top side and the bottom side of the magnetic preservation space 201. In addition, the magnetic field preservation container 200 also includes two magnetic conductive connectors 270. The two magnetic conductive connectors 270 are respectively arranged on opposite sides (left side and right side) of the magnetic preservation space 201, and each magnetic conductive connector 270 is used to connect the two magnetic field generating modules 260.

[0058] It should be noted that, in some other embodiments, the two magnetic field generating modules may also be respectively arranged on the left and right sides or the front and rear sides of the magnetic fresh-keeping space. Alternatively, in some other embodiments, the magnetic conductive connector may not be arranged. In addition, in some other embodiments, only one magnetic field generating module may be arranged, and the magnetic field generating module is arranged on one side of the magnetic fresh-keeping space.

[0059] In the scheme of the present embodiment, a magnetic preservation space 201 which is independently refrigerated and insulated is formed in the magnetic field preservation container 200, and a magnetic field generating module 260 is used to generate a magnetic field in the magnetic preservation space 201, so that the interior of the magnetic preservation space 201 can have a storage temperature different from that of the cold storage compartment of the refrigerator, thereby realizing magnetic field preservation storage of food. The magnetic field not only helps the food to maintain a supercooled degree at a lower temperature, but also has a certain sterilization effect, thereby helping to improve the preservation effect of the stored food.

[0060] By providing the magnetic conductive connector 270 , the magnetic field generated by the magnetic field generating module 260 can be guided and gathered, which helps to concentrate the magnetic field generated by the magnetic field generating module 260 in the magnetic preservation space 201 and distribute it more evenly in the magnetic preservation space 201 .

[0061] The structure of the magnetic field preservation container 200 is further described in detail below in conjunction with the accompanying drawings.

[0062] like Figures 7 to 9 As shown, in some embodiments, the barrel body 210 includes an upper shell 2101 and a lower shell 2102, and the upper shell 2101 and the lower shell 2102 are spliced ​​in the longitudinal direction to form the outer side wall of the barrel body 210. Specifically, the upper shell 2101 forms the top wall of the barrel body 210, and the lower shell 2102 forms the bottom wall of the barrel body 210. In addition, the upper shell 2101 and the lower shell 2102 together form the left side wall, the right side wall and the rear side wall of the barrel body 210.

[0063] Those skilled in the art can understand that, by setting the barrel body 210 as a structure formed by splicing the upper shell 2101 and the lower shell 2102, the components inside the barrel body 210 can be installed first during the production process, and then the upper shell 2101 and the lower shell 2102 can be spliced, thereby facilitating the production and assembly of the barrel body 210. In addition, in the subsequent maintenance process, the upper shell 2101 and the lower shell 2102 can also be disassembled to repair the inside of the barrel body 210, thereby facilitating the maintenance of the barrel body 210.

[0064] It should be noted that, in some other embodiments, the barrel body may also be an integrally formed structure, that is, the entire outer side wall of the barrel body is an integrally formed structure.

[0065] like Figures 7 to 10 As shown, the upper shell 2101 and the lower shell 2102 are connected by a snap-fit ​​structure. Specifically, the upper shell 2101 is provided with a snap 2103, and the lower shell 2102 is provided with a snap protrusion 2104. The snap 2103 is snapped into the snap protrusion 2104 to achieve the connection between the upper shell 2101 and the lower shell 2102.

[0066] Reference Figures 2 to 6 ,as well as Fig.11 As shown, the magnetic field generating module 260 on the top side of the magnetic fresh-keeping space 201 is arranged between the top insulation layer 230 and the top wall of the barrel body 210, and the magnetic field generating module 260 on the bottom side of the magnetic fresh-keeping space 201 is arranged outside the bottom wall of the barrel body 210. Taking one magnetic field generating module 260 as an example, the magnetic field generating module 260 includes a plurality of permanent magnetic sheets 261. The magnetic field fresh-keeping container 200 also includes a positioning structure 280, and the positioning structure 280 is formed with a plurality of installation areas 281, and the permanent magnetic sheets 261 and the installation areas 281 correspond one to one to locate the relative positions between the plurality of permanent magnetic sheets 261.

[0067] Reference Figures 2 to 6 ,as well as Fig.11 As shown, the positioning structure 280 is a mounting bracket, and the mounting bracket has a plurality of mounting areas 281 formed by hollowing out. Specifically, the mounting bracket is formed by hollowing out a plurality of through holes in the same shape as the permanent magnet pieces 261 on the flat plate. The number of mounting areas 281 is the same as the number of permanent magnet pieces 261, and each permanent magnet piece 261 can be installed in a corresponding mounting area 281.

[0068] It is understood by those skilled in the art that, by providing a plurality of permanent magnets 261 and a positioning structure 280, on the one hand, a plurality of permanent magnets 261 can be used to generate a magnetic field in the magnetic preservation space 201, that is, different positions in the magnetic preservation space 201 are all generated by the same permanent magnet 261 to generate a magnetic field, thereby helping to improve the uniformity of the magnetic field in the magnetic preservation space 201 and improve the preservation effect. On the other hand, the plurality of installation areas 281 of the positioning structure 280 can locate the relative positions between the plurality of permanent magnets 261, which not only facilitates the installation of the plurality of permanent magnets 261, but also makes the spacing between the plurality of permanent magnets 261 after installation meet the preset requirements, thereby ensuring a better magnetic field effect.

[0069] like Figure 2 and Fig.11 As shown, in some embodiments, the magnetic field generating module 260 further includes a shimming plate 262, which is disposed on the side of all permanent magnet pieces 261 facing away from the barrel body 210. In other words, the shimming plate 262 covers all permanent magnet pieces 261 in the direction facing the barrel body 210. By providing the shimming plate 262, the magnetic field generated by the permanent magnet pieces 261 can be guided, thereby improving the uniformity of the magnetic field generated by the permanent magnet pieces 261 in the magnetic preservation space 201.

[0070] like Fig.11 As shown, a pressing groove 2621 is formed on one side of the shimming plate 262 facing the permanent magnet sheet 261. The mounting bracket and the permanent magnet sheet 261 are arranged in the pressing groove 2621. In addition, a positioning protrusion 282 is provided at the edge of the mounting bracket (positioning structure 280 in the figure), and a positioning notch 2622 corresponding to the positioning protrusion 282 is provided at the edge of the shimming plate 262. The positioning protrusion 282 extends into the positioning notch 2622 to determine the installation direction of the mounting bracket relative to the shimming plate 262.

[0071] like Fig.11 As shown, specifically, the positioning protrusion 282 is formed on the edge of the mounting bracket and deviates from the central axis, and correspondingly, the positioning notch 2622 is formed on the edge of the uniform magnetic plate 262 and deviates from the central axis, so that the installation direction of the mounting bracket can be positioned by utilizing the matching relationship between the positioning protrusion 282 and the positioning notch 2622.

[0072] Those skilled in the art can understand that by providing the pressing groove 2621 on the magnetic shimming plate 262, providing the positioning protrusion 282 on the mounting bracket, and providing the positioning notch 2622 on the magnetic shimming plate 262, the mounting bracket and the permanent magnet sheet 261 can be placed in the pressing groove 2621, which can not only play a positioning role in the cooperation between the mounting bracket, the permanent magnet sheet 261 and the magnetic shimming plate 262, but also help to improve the stability after assembly. The positioning protrusion 282 and the positioning notch 2622 can also play a positioning role in the mounting bracket, making it easier to install.

[0073] like Figures 11 to 13 As shown, the permanent magnet piece 261 is in the shape of a square with one corner missing, and the shape of the mounting area 281 is the same as that of the permanent magnet piece 261, so as to indicate the assembly direction of the missing corner portion of the permanent magnet piece 261. Specifically, the shape of the missing corner square makes the permanent magnet piece 261 and the mounting area 281 have only one assembly relationship.

[0074] What those skilled in the art can understand is that by making the permanent magnet piece 261 into a square shape with one corner missing, and making the shape of the installation area 281 the same as that of the permanent magnet piece 261, there is only one assembly relationship between the permanent magnet piece 261 and the installation area 281. Therefore, after all the permanent magnet pieces 261 are installed in place, the magnetic field directions of all the permanent magnet pieces 261 can be ensured to be consistent, thereby ensuring that all the permanent magnet pieces 261 generate the correct magnetic field.

[0075] It should be noted that the permanent magnet sheet can be a rectangular square or a rounded square.

[0076] like Figures 2 to 5 As shown, the cold air circuit for cooling the magnetic preservation space 201 surrounds the interior space of the drawer 220, including a top section 203 located on the top side of the interior space of the drawer 220, a front section 204 located on the front side of the interior space of the drawer 220, and a bottom section 205 located at the bottom of the interior space of the drawer 220.

[0077] Reference Figures 2 to 5 As shown, the top section 203 is formed between the top insulation layer 230 and the magnetic field generating module 260. Specifically, the top insulation layer 230 and the uniform magnetic plate 262 of the magnetic field generating module 260 together surround the top section 203. In addition, the magnetic field preservation container 200 is formed with an air inlet 206 connected to the top section 203. The air inlet 206 is connected to the air supply port of the refrigeration space of the refrigerator body, so that the cold air generated in the refrigeration space can enter the top section 203 through the air inlet 206.

[0078] Reference Figures 2 to 5 As shown, the front section 204 is formed inside the front panel of the drawer 220. Specifically, the front panel of the drawer 220 has a thicker and hollow portion for forming the front section 204. In addition, the top of the front section 204 has an opening, and the front end of the top section 203 has an opening. The cold air flow in the top section 203 flows to the top opening of the front section 204 through the front end opening, and then enters the front section 204.

[0079] Reference Figures 2 to 5 As shown, the bottom section 205 is formed between the bottom wall of the drawer 220 in the closed state and the inner bottom wall of the barrel 210. The bottom of the front section 204 has an opening, and the cold air flow in the front section 204 flows into the bottom section 205 through the bottom opening, that is, into the magnetic fresh-keeping space 201.

[0080] Reference Figures 2 to 5 as well as Fig. 9 As shown, in addition, the rear side wall of the barrel body 210 is provided with an air hole 2105, and the cold air flow entering the bottom section 205 flows from front to back, flows to the rear of the magnetic fresh-keeping space 201, and then flows out of the magnetic fresh-keeping space 201 from the air hole 2105. An air guide duct connected to the air hole 2105 is formed between the rear insulation layer 250 and the rear side wall of the barrel body 210. In addition, the magnetic field fresh-keeping container 200 is formed with an air outlet 207 connected to the air guide duct, and the air outlet 207 is connected to the return air outlet of the refrigerator body refrigeration space. The cold air flow flowing out of the air hole 2105 flows to the air outlet 207 via the air guide duct, and then returns to the refrigeration space of the refrigerator, completing the refrigeration of the magnetic fresh-keeping space 201, mainly the internal space of the drawer 220.

[0081] It will be understood by those skilled in the art that, through the above-mentioned structural configuration, while cooling the internal space of the drawer 220, cold air can be prevented from blowing directly into the internal space of the drawer 220, so as to prevent the temperature of the stored objects placed in the internal space of the drawer 220 from dropping too quickly, thereby smoothly reaching the temperature required for magnetic field preservation and better realizing magnetic field preservation.

[0082] It should be noted that, in some other embodiments, only the top section may be provided, and the cold air flow directly flows out of the magnetic field preservation container from the front of the top section and enters the cold storage compartment of the refrigerator.

[0083] Reference Figures 2 to 4 In some embodiments, the magnetic field fresh-keeping container 200 includes a top cover 290, which is arranged on the top of the top insulation layer 230. The side wall of the top cover 290 covers part of the side insulation layer 240, and the rear wall of the top cover 290 covers part of the rear insulation layer 250. The top cover 290 is fixed to the side insulation layer 240, and the top cover 290 is fixed to the rear insulation layer 250, such as by screws, so as to strengthen the cooperation between the top insulation layer 230, the side insulation layer 240 and the rear insulation layer 250.

[0084] Reference Fig.14 As shown, in some embodiments, different from the above embodiments, the positioning structure 280 is a mounting plate, and the mounting plate is formed with a plurality of grooves as the mounting area 281. That is, the permanent magnet sheet is installed in the groove of the mounting plate. By using the grooves on the mounting plate to install the permanent magnet sheet, the structure is more stable.

[0085] In addition, it should be noted that the shim plate can be directly used as a mounting plate, thereby simplifying the structure on the basis of utilizing the shim plate to uniformly form a magnetic field.

[0086] Reference Fig.11 and Fig.14As shown, in some embodiments, the positioning structure 280 is fixedly connected to the permanent magnet sheet 261 so that the positioning structure 280 and the permanent magnet sheet 261 form a whole. Specifically, the positioning structure 280 and the permanent magnet sheet 261 can be fixed together by gluing or insert injection molding. By fixing the positioning structure 280 and the permanent magnet sheet 261 into a whole, modular assembly is facilitated to improve assembly convenience.

[0087] like Fig.15 As shown, in some embodiments, the positioning structure 280 is the side wall of the barrel, and the side wall of the barrel is formed with a plurality of mounting grooves as the mounting area 281. Specifically, taking the magnetic field generating module arranged on the top of the barrel as an example, that is, the top wall of the barrel is used as the positioning structure 280, and the top wall of the barrel is formed with a plurality of mounting grooves as the mounting area 281, the permanent magnet piece is directly mounted in the mounting groove on the side wall of the barrel.

[0088] It can be understood by those skilled in the art that by utilizing the side wall of the barrel body as a positioning structure 280 and forming a plurality of mounting grooves on the side wall of the barrel body as mounting areas 281, the permanent magnet sheets can be installed on the side wall of the barrel body. On the basis of being able to locate the relative positions of a plurality of permanent magnet sheets, the permanent magnet sheets can be directly installed on the barrel body, thereby simplifying the installation work.

[0089] It should be noted that the permanent magnet sheet and the side wall of the barrel body can also be directly injection molded into an integrated structure.

[0090] Although not shown in the figure, in some embodiments, it is easy to understand that the positioning structure is a plastic film, and the plastic film is formed with multiple installation cavities as installation areas. In other words, multiple permanent magnet sheets are plastic-sealed together using the plastic film to locate the relative positions between the multiple permanent magnet sheets.

[0091] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
