[0040] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within 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.

[0041] like Figure 1 As shown, in one embodiment, the refrigeration device 10 includes a housing 100 and a food preservation storage device 200. The housing 100 is provided with a storage compartment 101. The food preservation storage device 200 is disposed in the storage compartment 101. The food preservation storage device 200 is the food preservation storage device described in any of the embodiments below.

[0042] 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 fresh-keeping storage device 200 can be installed in one or more of the storage chambers.

[0043] like Figures 2 to 5 As shown, in one embodiment, the food preservation storage device 200 includes a storage container 210, a magnetic field device 220, a telescopic member 230, and a stop member 240. The storage container 210 is provided with a storage space 201. The magnetic field device 220 includes a housing 221 and a magnetic field generator 222, which is disposed inside the housing 221 and is used to generate a magnetic field within the storage space 201. The magnetic field generator 222 is a permanent magnet.

[0044] 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.

[0045] Reference Figures 2 to 5 As shown, the telescopic member 230 is disposed on the housing 221, and the stop member 240 is disposed on the storage container 210. The telescopic member 230 can abut against the stop member 240 to install the magnetic field device 220 in the storage container 210, and can disengage from the stop member 240 by contraction to allow the magnetic field device 220 to disengage from the storage container 210.

[0046] In this embodiment, one of the telescopic member 230 and the stop member 240 is disposed on the outer shell 221 of the magnetic field device 220, and the other is disposed on the storage container 210. The telescopic member 230 can abut against the stop member 240 to install the magnetic field device 220 on the storage container 210, and can be disengaged from the storage container 210 by contraction. In other words, the telescopic member 230 and the stop member 240 cooperate to allow the magnetic field device 220 to be detachably installed on the storage container 210. The magnetic field device 220 installed on the storage container 210 can generate a magnetic field within the storage space 201, thereby subjecting the food in the storage space 201 to the magnetic field during low-temperature storage, achieving a magnetic field preservation effect and improving the preservation effect of the food. At the same time, it facilitates the replacement and maintenance of the magnetic field device 220. Furthermore, the outer casing 221 protects the magnetic field generator 222 from friction or impact during use, thus extending its service life. Additionally, the magnetic field device 220 can be fixed to the storage container 210 via the outer casing 221. Compared to directly fixing the magnetic field generator to the storage container, this eliminates the need for additional fitting structures on the magnetic field generator 222, reducing the need for special design features and simplifying production.

[0047] Furthermore, by mounting the telescopic component 230 on the outer casing 221, the telescopic component 230 can be detached from the storage container 210 along with the magnetic field device 220. Because the telescopic component 230 is a moving part, it is more prone to problems than the stop component 240. Therefore, allowing the telescopic component 230 to be detached from the storage container 210 along with the magnetic field device 220 facilitates the inspection or maintenance of the telescopic component 230.

[0048] It should be noted that in some other embodiments, the telescopic member may be located in the storage container, while the stop member may be located in the outer shell.

[0049] It should be noted that in some other embodiments, the magnetic field device may not have a housing, but instead the telescopic or stop components may be directly mounted on the permanent magnet sheet that serves as the magnetic field generator.

[0050] Continue to refer to Figures 2 to 5 As shown, the magnetic field device 220 is fitted to the side wall of the storage container 210. The telescopic member 230 and the stop member 240 abut against each other along the axial direction of the side wall of the storage container 210 to which the magnetic field device 220 is fitted, thereby preventing the magnetic field device 220 from detaching from the side wall of the storage container 210 to which it is fitted.

[0051] like Figures 2 to 5As shown, in one embodiment, the storage container 210 is a drawer, meaning that the storage container 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 a top opening. The magnetic field device 220 has a generally flat plate-like structure and is disposed on the inner surface of the bottom side wall of the drawer, with the bottom side of the magnetic field device 220 fitting against the inner surface of the bottom side wall of the drawer.

[0052] Reference Figures 2 to 5 As shown, the food preservation storage device 200 includes two sets of telescopic components 230 and stop components 240, which are respectively arranged on opposite sides of the magnetic field device 220. Specifically, the two telescopic components 230 are respectively arranged on the left and right sides of the outer casing 221, and the two stop components 240 are respectively arranged on the drawer at positions corresponding to the two telescopic components 230. Both telescopic components 230 extend and retract along the left and right direction of the drawer.

[0053] Continue to refer to Figures 2 to 5 As shown, regarding the telescopic member 230 and the stop member 240 on the left side of the magnetic field device 220, the stop member 240 is located to the left of the telescopic member 230. The telescopic member 230 and the stop member 240 can abut against each other in the vertical direction, thereby preventing the magnetic field device 220 from detaching upward from the bottom side wall of the drawer. Furthermore, the telescopic member 230 can retract to the right, thereby disengaging from the abutment with the stop member 240.

[0054] Regarding the telescopic member 230 and the stop member 240 on the right side of the magnetic field device 220, the stop member 240 is located to the right of the telescopic member 230. The telescopic member 230 and the stop member 240 can abut against each other in the vertical direction, thereby preventing the magnetic field device 220 from detaching upward from the bottom side wall of the drawer. Furthermore, the telescopic member 230 can retract to the left, thereby disengaging from the abutment with the stop member 240.

[0055] Those skilled in the art will understand that by fitting the magnetic field device 220 against the side wall of the storage container 210, the fit between the magnetic field device 220 and the storage container 210 becomes more stable. Moreover, when the magnetic field device 220 is located on the inner side wall of the storage container 210, it also avoids the magnetic field device 220 occupying too much of the storage space 201 area.

[0056] It should be noted that in some other embodiments, the magnetic field device may also be fixed at a position with a certain distance from the side wall of the storage container.

[0057] In addition, by setting the storage container 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.

[0058] It should be noted that in some other embodiments, the storage container may also have other structures, such as a box-shaped structure with only a front opening. Additionally, the magnetic field device may be disposed on the inner or outer surface of any side wall of the storage container. Alternatively, the magnetic field device may be disposed on multiple side walls of the storage container.

[0059] In addition, by setting two sets of telescopic components 230 and stop components 240, which are respectively set on opposite sides of the magnetic field device 220, the stability of the magnetic field device 220 after installation is improved.

[0060] like Figures 2 to 6 As shown, the outer casing 221 includes a first shell 2211 and a second shell 2212, which together form a mounting cavity 202. A magnetic field generator 222 is disposed within the mounting cavity 202. Specifically, the first shell 2211 and the second shell 2212 are interlocked along the axial direction of the sidewall of the attached storage container 210 to form the mounting cavity 202. The axial direction of the sidewall is the straight line extending perpendicular to the surface of the sidewall facing the storage space 201.

[0061] Reference Figures 2 to 6 As shown, the magnetic field device 220 is disposed on the inner surface of the bottom side wall of the drawer. The axis of the bottom side wall of the drawer is the line extending longitudinally, that is, the first housing 2211 and the second housing 2212 are interlocked with each other longitudinally, that is, the first housing 2211 and the second housing 2212 are interlocked with each other in the vertical direction.

[0062] Those skilled in the art will understand that by providing the first housing 2211 and the second housing 2212, the magnetic field generator 222 is disposed within the mounting cavity 202 formed by the first housing 2211 and the second housing 2212, facilitating the placement and removal of the magnetic field generator 222 within the outer casing 221. Furthermore, by interlocking the first housing 2211 and the second housing 2212 along the axial direction of the side wall of the attached storage container 210, the first housing 2211 and the second housing 2212 can clamp the magnetic field generator 222, thereby helping to ensure the stability of the shape of the magnetic field generator 222.

[0063] 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 container.

[0064] like Figures 2 to 6As shown, the first housing 2211 is located on the side of the second housing 2212 facing the storage space 201. One of the telescopic member 230 and the stop member 240 is disposed on the first housing 2211. The magnetic field device 220 is disposed against the bottom side wall of the drawer, and the first housing 2211 is located above the second housing 2212. Specifically, the edge of the first housing 2211 forms a flange, and the edge of the second housing 2212 also forms a flange. The area enclosed by the flange of the first housing 2211 can surround the area enclosed by the flange of the second housing 2212, thereby engaging with the second housing 2212. The telescopic member 230 is disposed on the left and right sides of the first housing 2211, that is, the left flange and the right flange.

[0065] Those skilled in the art will understand that, with the first housing 2211 and the second housing 2212 interlocked along the axial direction of the side wall of the attached storage container 210, the first housing 2211 is positioned on the side of the second housing 2212 facing the storage space 201, and one of the telescopic member 230 and the stop member 240 is positioned on the first housing 2211. After the magnetic field device 220 is assembled with the storage container 210, the first housing 2211 can directly prevent the second housing 2212 from detaching from the side wall of the storage container 210, eliminating the need for additional connections between the first housing 2211 and the second housing 2212, thus simplifying the structure.

[0066] 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.

[0067] like Figure 6 As shown, in one embodiment, the magnetic field device 220 further includes a uniform magnetic plate 223, which is disposed within the housing 221 and on the side of the magnetic field generator 222 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 223 is disposed on the bottom side of the magnetic field generator 222. The uniform magnetic plate 223 is made of a magnetically conductive material, such as silicon steel, and can guide the magnetic field generated by the magnetic field generator 222, making the magnetic field generated by the magnetic field generator 222 more uniformly distributed in the storage space 201.

[0068] like Figures 2 to 8 As shown, the telescopic member 230 includes a spring 231 and a locking post 232. The spring 231 is disposed between the locking post 232 and the outer casing 221. The spring 231 is configured to provide a force that supports the locking post 232 in a position abutting against the stop member 240, and the spring 231 is also configured to be compressed by the locking post 232, causing the locking post 232 to disengage from the stop member 240. Furthermore, the stop member 240 has a slot 241, in which the locking post 232 is inserted, thereby abutting against the stop member 240.

[0069] like Figures 7 to 8 As shown, taking the telescopic member 230 located on the left side of the first housing 2211 as an example, the left side of the first housing 2211 extends to the left to form a guide sleeve. The guide sleeve has a guide groove, and a spring 231 is located in the guide groove. A locking post 232 is located to the left of the spring 231, and the spring 231 extends and retracts in the left-right direction. The opening of the locking groove 241 of the stop member 240 faces to the right. When the magnetic field device 220 and the storage container 210 are assembled in place, the locking post 232 is inserted into the locking groove 241 to the left, and the spring 231 applies pressure to the locking post 232 to the left, supporting the locking post 232 in the locking groove 241. When it is necessary to remove the magnetic field device 220, the locking post 232 is compressed to the right by the spring 231, thereby causing the locking post 232 to disengage from the locking groove 241.

[0070] In this embodiment, by providing a spring 231 and a locking post 232, with the spring 231 positioned between the locking post 232 and the outer casing 221, the spring 231 is configured to provide a force supporting the locking post 232 in a position abutting against the stop member 240. Furthermore, the spring 231 is configured to be compressed by the locking post 232, causing the locking post 232 to disengage from the stop member 240, thus allowing the telescopic member 230 to be more stably maintained in the position abutting against the stop member 240. By providing a slot 241 in the stop member 240, the stop member 240 can abut against the telescopic member 230 in multiple directions, effectively preventing the magnetic field device 220 from detaching from the storage container 210 while also preventing excessive movement of the magnetic field device 220.

[0071] It should be noted that in some other embodiments, the telescopic component may not have a spring, meaning that both extension and retraction require manual operation.

[0072] It should be noted that in some other implementations, the stop can also be a baffle.

[0073] like Figures 2 to 8 As shown, the locking post 232 has a guide surface, which is located on the side of the locking post 232 facing the side wall of the storage container 210 to which the magnetic field device 220 is attached, and is inclined in the direction away from the side wall of the attached storage container 210 along the direction pointing to the corresponding stop 240. (Refer to...) Figure 8As shown, taking the telescopic member 230 located on the left side of the first housing 2211 as an example, the guide surface of the locking post 232 is inclined to the upper left. During the assembly process of the magnetic field device 220 and the storage container 210, the guide surface of the locking post 232 first contacts the stop member 240. Under the guidance of the guide surface, the locking post 232 compresses the spring 231 to the right. When the locking post 232 is aligned with the slot 241, the locking post 232 can be inserted into the slot 241 under the elastic force of the spring 231. In this way, there is no need to manually compress the spring 231 during the installation process, improving the convenience of installation.

[0074] like Figure 7 and Figure 8 As shown, the locking post 232 is equipped with an operating rod 233, which extends radially from the side of the locking post 232. Specifically, the guide sleeve is provided with a clearance hole, which has a certain length along the extension and retraction direction of the locking post 232. The operating rod 233 extends out of the guide groove from the clearance hole, so that the locking post 232 can be manually moved via the operating rod 233 for easy operation.

[0075] like Figures 2 to 5 As shown, the storage container 210 to which the magnetic field device 220 is attached has multiple positioning ribs 211 on its side wall. 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 telescopic member 230 and the stop member 240 to connect more quickly.

[0076] 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.
