For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can also refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] like Figure 1 As shown, in one embodiment, the refrigeration device 10 includes a housing 100 and a magnetic field preservation container 200. The housing 100 is provided with a storage compartment 101. The magnetic field preservation container 200 is disposed in the storage compartment 101. The magnetic field preservation container 200 is the magnetic field preservation container described in any of the embodiments below.

[0041] Generally, refrigeration equipment typically has multiple storage compartments, such as refrigeration compartments, freezer compartments, variable temperature compartments, etc. Figure 1 This illustration only shows one storage chamber 101 of the refrigeration equipment. The storage chamber 101 can be any type of storage chamber that can be installed in the refrigeration equipment. For the refrigeration equipment of this application, those skilled in the art can configure the specific number, function, and layout of the storage chambers according to their needs. The magnetic field preservation container 200 can be installed in one or more of the storage chambers.

[0042] like Figures 2 to 6 As shown, in one embodiment, the magnetic field preservation container 200 includes a storage component 210, a magnetic field device 220, and a fixing structure 230. The storage component 210 has a storage space 201 for storing stored items. The magnetic field device 220 includes a first housing 221, a second housing 222, and a magnetic field generator 223. The first housing 221 and the second housing 222 form a mounting cavity 202. The magnetic field generator 223 is disposed within the mounting cavity 202 and is used to generate a magnetic field within the storage space 201. The fixing structure 230 is used to fix the magnetic field device 220 to the storage component 210. The magnetic field device 220 fixed to the storage component 210 can generate a magnetic field within the storage space 201 using the magnetic field generator 223, thereby subjecting the food stored in the storage space 201 to the magnetic field and improving the food preservation effect. Specifically, the magnetic field generator 223 is a permanent magnet.

[0043] It should be noted that in some other embodiments, the magnetic field generator may be a single electromagnetic coil or an electromagnetic coil and a permanent magnet sheet.

[0044] In this embodiment, the magnetic field device 220 is fixed to the storage unit 210 using a fixing structure 230. The magnetic field device 220 includes a first housing 221, a second housing 222, and a magnetic field generator 223, which is disposed within the mounting cavity 202 formed by the first housing 221 and the second housing 222. The magnetic field device 220, fixed to the storage unit 210, can generate a magnetic field within the storage space 201 using the magnetic field generator 223. This allows the food within the storage space 201 to be subjected to the magnetic field during low-temperature storage, achieving a magnetic field preservation effect and improving the food's freshness. Furthermore, the first housing 221 and the second housing 222 protect the magnetic field generator 223, preventing it from being subjected to friction or impact during use, thus helping to extend its service life. In addition, the magnetic field device 220 can be fixed to the storage component 210 via the first housing 221 and the second housing 222. Compared with the magnetic field generator being directly fixed to the storage component, there is no need to set an additional mating structure on the magnetic field generator 223, which reduces the special design of the magnetic field generator 223 and facilitates production.

[0045] like Figures 2 to 6 As shown, the fixing structure 230 includes a first mating member 231 and a second mating member 232. The first mating member 231 is disposed on the magnetic field device 220, and the second mating member 232 is disposed on the storage component 210. The first mating member 231 and the second mating member 232 are detachably mated to fix the magnetic field device 220 to the storage component 210.

[0046] Those skilled in the art will understand that by configuring the fixing structure 230 as a detachable first mating part 231 and a second mating part 232, the magnetic field device 220 can be detachably fixed to the storage unit 210, which facilitates the replacement and maintenance of the magnetic field device 220.

[0047] It should be noted that in some other embodiments, the fixing structure may also be an adhesive or welded structure.

[0048] like Figures 2 to 6 As shown, the magnetic field device 220 is attached to the side wall of the storage component 210. The edge of the magnetic field device 220 and the corresponding edge of the side wall of the attached storage component 210 have a mating interval 203. The first mating component 231 extends from the surface of the magnetic field device 220 into the area of ​​the mating interval 203. The second mating component 232 is disposed in the area of ​​the mating interval 203 and corresponds to the position of the first mating component 231.

[0049] like Figures 2 to 6As shown, specifically, the storage component 210 is a drawer, meaning that the storage component 210 has a front side wall, a rear side wall, a left side wall, a right side wall, and a bottom side wall, which together form a storage space 201 with an open top. The magnetic field device 220 has a flat, plate-like structure and is located on the inner surface of the bottom side wall of the drawer, with the bottom side of the magnetic field device 220 fitting snugly against the inner surface of the bottom side wall of the drawer.

[0050] Reference Figure 2 As shown in the enlarged portion, there is a mating interval 203 between the right edge of the magnetic field device 220 and the right edge of the drawer bottom sidewall. The first mating member 231 extends from the surface of the magnetic field device 220 into the area of ​​the mating interval 203. The second mating member 232 is disposed on the inner surface of the drawer bottom sidewall and located in the area of ​​the mating interval 203. At the same time, the positions of the second mating member 232 and the first mating member 231 correspond to each other, so that they can cooperate with each other to fix the magnetic field device 220.

[0051] Those skilled in the art will understand that by attaching the magnetic field device 220 to the side wall of the storage component 210, the fit between the magnetic field device 220 and the storage component 210 becomes more stable. Furthermore, when the magnetic field device 220 is positioned inside the side wall of the storage component 210, it avoids occupying too much of the storage space 201. Additionally, a mating interval 203 is provided between the edge of the magnetic field device 220 and the corresponding edge of the side wall of the attached storage component 210, facilitating the placement of the first mating component 231 and the second mating component 232.

[0052] It should be noted that in some other embodiments, the second mating member may also be disposed on the sidewall adjacent to the sidewall that is in contact with the magnetic field device. For example, if the magnetic field device is disposed on the inner surface of the bottom sidewall, the second mating member may also be disposed on the inner surface of the right sidewall of the storage unit. Additionally, in some other embodiments, the magnetic field device may be fixed at a position with a certain distance from the sidewall of the storage unit.

[0053] In addition, by setting the storage unit 210 as a drawer and setting the magnetic field device 220 on the bottom side wall of the drawer, since drawers are usually structures with a large bottom area and a small height, setting the magnetic field device 220 on the bottom side wall of the drawer makes it easier for the magnetic field generated by the magnetic field device 220 to be fully distributed in the storage space 201.

[0054] It should be noted that in some other embodiments, the storage component can also have other structures, such as a box-shaped structure with only a front opening. Additionally, the magnetic field device can be disposed on the inner or outer surface of any side wall of the storage component. Alternatively, the magnetic field device can be disposed on multiple side walls of the storage component.

[0055] like Figures 2 to 6As shown, in one embodiment, the first housing 221 and the second housing 222 are interlocked along the axial direction of the side wall of the attached storage component 210 to form a mounting cavity 202. Specifically, the magnetic field device 220 is disposed against the bottom side wall of the drawer, and the first housing 221 and the second housing 222 are interlocked along the axial direction of the bottom side wall of the drawer, that is, interlocked in the vertical direction. The above structure allows the first housing 221 and the second housing 222 to clamp the magnetic field generator 223, thereby helping to ensure the stability of the shape of the magnetic field generator 223.

[0056] It should be noted that in some other embodiments, the first housing and the second housing may also be interlocked along an axis perpendicular to the sidewall of the attached storage component.

[0057] like Figures 2 to 6 As shown, when the first housing 221 and the second housing 222 are interlocked along the axial direction of the side wall of the attached storage component 210, the first housing 221 is located on the side of the second housing 222 facing the storage space 201, and the first mating part 231 is provided on the first housing 221. Specifically, the magnetic field device 220 is disposed against the bottom side wall of the drawer, and the first housing 221 is located above the second housing 222. The first mating part 231 is provided on the first housing 221, that is, the first housing 221 cooperates with the second mating part 232 on the side wall of the storage component 210 to fix the magnetic field device 220.

[0058] Those skilled in the art will understand that, with the first housing 221 and the second housing 222 interlocked along the axial direction of the bottom sidewall of the drawer, the first housing 221 is positioned on the side of the second housing 222 facing the storage space 201, and the first mating part 231 is positioned on the first housing 221. After the first mating part 231 on the first housing 221 is assembled with the second mating part 232 on the sidewall of the storage component 210, the first housing 221 can directly prevent the second housing 222 from detaching from the sidewall of the storage component 210, eliminating the need for additional connections between the first housing 221 and the second housing 222, thus simplifying the structure.

[0059] It should be noted that in some other embodiments, the first housing and the second housing can also be fixedly connected by a connecting structure.

[0060] like Figures 2 to 6 As shown, in one embodiment, the fixing structure 230 includes two first mating parts 231 and two second mating parts 232. The two first mating parts 231 are disposed on opposite sides of the magnetic field device 220, and the two second mating parts 232 are disposed on the side wall of the storage component 210 to which the magnetic field device 220 is attached and correspond to the positions of the two first mating parts 231 respectively.

[0061] Reference Figures 2 to 6 As shown, two first mating parts 231 are respectively disposed on the left and right sides of the magnetic field device 220, and the positions of two second mating parts 232 correspond to the positions of the two first mating parts 231. By setting two first mating parts 231 and two second mating parts 232, and placing the two first mating parts 231 on opposite sides of the magnetic field device 220, it helps to improve the stability of the magnetic field device 220.

[0062] like Figures 2 to 4 As shown, the side wall of the storage component 210 to which the magnetic field device 220 is attached is provided with multiple positioning ribs 211. The multiple positioning ribs 211 are respectively arranged on opposite sides of the magnetic field device 220 to clamp and position the magnetic field device 220, thereby facilitating the positioning of the magnetic field device 220 during installation and enabling the first mating component 231 and the second mating component 232 to connect more quickly.

[0063] like Figure 5 and Figure 6 As shown, the magnetic field device 220 also includes a uniform magnetic plate 224, which is disposed within the mounting cavity 202 and on the side of the magnetic field generator 223 opposite to the storage space 201. Specifically, the magnetic field device 220 is disposed on the inner surface of the bottom side wall of the drawer, and the uniform magnetic plate 224 is disposed on the bottom side of the magnetic field generator 223. The uniform magnetic plate 224 is made of a magnetically conductive material, such as silicon steel, and can guide the magnetic field generated by the magnetic field generator 223, making the magnetic field generated by the magnetic field generator 223 more uniformly distributed in the storage space 201.

[0064] like Figures 2 to 4 As shown, in one embodiment, the first mating member 231 is a locking post and the second mating member 232 is a locking claw. The locking post is embedded in the locking claw to fix the magnetic field device 220 to the side wall of the storage member 210.

[0065] Reference Figures 2 to 6 As shown, specifically, the edge of the first housing 221 is formed with a flange, and the edge of the second housing 222 is also formed with a flange. The area enclosed by the flange of the first housing 221 can surround the area enclosed by the flange of the second housing 222, thereby engaging with the second housing 222.

[0066] Continue to refer to Figures 2 to 6As shown, two locking posts are respectively located on the left and right sides of the magnetic field device 220, that is, the left and right flanges of the first housing 221. Correspondingly, two second mating parts 232, i.e., locking claws, are located on the inner surface of the bottom sidewall of the storage component 210 and are positioned on the left and right sides of the magnetic field device 220 to correspond with the locking posts. The locking posts extend into the mating interval 203 area in a direction perpendicular to the side of the magnetic field device 220. The locking claws are elastic structures with annular top openings. During the installation of the magnetic field device 220, the locking posts are forced open by external force and enter the circular area enclosed by the locking claws. Then, the top openings of the locking claws return to their initial opening size under the action of elastic force, thereby clamping the locking posts and fixing the magnetic field device 220 to the inner surface of the bottom sidewall of the storage component 210.

[0067] It should be noted that in some other embodiments, the first mating member may also be disposed on the side of the magnetic field device away from the side wall of the storage item it is attached to, that is, the first mating member may be disposed on other sides of the magnetic field device other than the side that is attached to the storage item.

[0068] like Figures 7 to 10 As shown, in one embodiment, the first mating member 231 has a first threaded hole 2311, and the second mating member 232 has a second threaded hole 2321. The first threaded hole 2311 and the second threaded hole 2321 are fixed by screws, thereby fixing the magnetic field device 220 to the side wall of the storage member 210. Specifically, the first mating member 231 is a sheet-like structure extending outward from the side of the magnetic field device 220 to the mating interval 203 region, and is provided with a longitudinal first threaded hole 2311. The second mating member 232 is a columnar structure, and is provided with a longitudinal second threaded hole 2321. The sheet-like first mating member 231 rests on the top of the columnar second mating member 232, aligning the first threaded hole 2311 and the second threaded hole 2321, and then the first mating member 231 and the second mating member 232 are fixed together using screws.

[0069] It should be noted that in some other embodiments, the first mating component and the second mating component may also be mating snap-fit ​​structures, Velcro structures, etc.

[0070] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of 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.
