Description

Technical Field

[0001] The utility model relates to the technical field of cold storage, in particular to a refrigeration device and a magnetic field module for a refrigeration device. Background Art

[0002] Refrigeration devices such as refrigerators, as a type of common electrical appliances, can store food materials at low temperature, thereby extending the storage period of food materials. Although refrigerators extend the storage period of food materials, the quality of food materials after low-temperature storage will inevitably decline to some extent. Through continuous research, it is found that magnetic fields have a good auxiliary effect on the low-temperature storage of food materials, which can not only further extend the preservation period of food materials, but also help to maintain the freshness of food materials during a longer storage time. Therefore, the field of refrigeration devices is also actively exploring the introduction of magnetic fields into refrigeration devices to achieve low-temperature storage under magnetic fields.

[0003] When installing a magnetic field component in a refrigeration device, in order to avoid occupying too much space, the magnetic field component usually adopts a relatively thin plate-shaped magnet, and its structural stability is not very strong, and it is easy to deform or be damaged when subjected to external collisions. Summary of the Utility Model

[0004] An object of the utility model is to provide a refrigeration device and a magnetic field module for a refrigeration device that can play a certain protective role in the magnetic field structure.

[0005] In particular, the utility model provides a magnetic field module for a refrigeration device, including:

[0006] A magnetic field component for generating a magnetic field;

[0007] A first grid frame and a second grid frame respectively arranged on opposite sides of the magnetic field component to clamp the magnetic field component; and

[0009] Optionally, at least one mounting post is provided on the grid ribs of the first grid frame, and the magnetic field component is provided with mounting holes for cooperating with the mounting posts so that the mounting posts are embedded in the mounting holes.

[0010] Optionally, the length of the mounting post is greater than the distance between the first grid frame and the second grid frame after being assembled in place, and the grid rib part of the second grid frame corresponding to the mounting post forms a bending part to avoid the mounting post.

[0011] Optionally, the setting position of the mounting post is offset from the center position of the first grid frame.

[0012] Optionally, the locking member includes a plurality of clamping clips that simultaneously clamp the first grid frame and the second grid frame to fix the first grid frame and the second grid frame together.

[0013] Optionally, the plurality of clamping clips are arranged at least on opposite sides of the first grid frame and the second grid frame.

[0014] Optionally, the magnetic field member includes a permanent magnet plate and a magnetic field homogenizing plate. The magnetic field homogenizing plate is arranged in contact with the permanent magnet plate, and the area of the magnetic field homogenizing plate is larger than that of the permanent magnet plate.

[0015] Optionally, the permanent magnet plate is integrally in the shape of a square with a corner missing, and the grids at the corners of the first grid frame and / or the second grid frame are provided with diagonal ribs to indicate the assembly direction of the missing corner part of the permanent magnet plate.

[0016] Optionally, the surfaces of the magnetic field homogenizing plate and the permanent magnet plate are provided with plastic sealing films.

[0018] A box body configured with a storage compartment; and

[0019] At least one magnetic field module according to any one of the above, the magnetic field module is arranged in the storage compartment to generate a magnetic field in the storage compartment.

[0020] In the magnetic field module of the present utility model, by respectively arranging the first grid frame and the second grid frame on opposite sides of the magnetic field member, the first grid frame and the second grid frame clamp the magnetic field member, and the locking member is used to fix the first grid frame and the second grid frame at the position where the magnetic field member is clamped.

At the same time, the first grid frame and the second grid frame clamp the magnetic field member, making the magnetic field member not easily deformed and improving the structural stability of the magnetic field member. Moreover, the cost of using the grid frame for protection and fixation is relatively low, and while playing the role of protection and fixation, the magnetic field member can be directly observed, facilitating certain inspection work on the magnetic field member without disassembly.

[0032] Further, it should also be noted that in the description of the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection, an indirect connection through an intermediate medium, or a communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] As Figure 1 shown, in one embodiment, the refrigeration device 1 includes a cabinet 100, two magnetic field modules 200, and a drawer 300. At least one storage compartment 101 is defined within the cabinet 100, usually multiple, such as a refrigerated storage compartment, a frozen storage compartment, a variable temperature storage compartment, etc. The specific number and functions of the storage compartments can be configured according to prior requirements. Figure 1 The illustrated refrigeration device 1 is only an example, and those skilled in the art can configure the specific number, functions, and layout of the storage compartments according to requirements. The magnetic field module 200 is disposed within the storage compartment 101 to generate a magnetic field within the storage compartment 101.

[0034] As Figure 1 shown, specifically, the drawer 300 is disposed within the storage compartment 101 for storing food ingredients, and the two magnetic field modules 200 are respectively disposed on the top side and the bottom side of the drawer 300 to apply a magnetic field to the food ingredients stored in the drawer 300.

[0035] It should be noted that in some other embodiments, the magnetic field module can be disposed on the inner or outer side wall of the drawer. In addition, the storage compartment can also be spatially divided by means of a shelf, a shelf board, etc. to achieve the corresponding function of storing food ingredients. Or, the food ingredients can also be stored by providing a storage box within the storage compartment, and the magnetic field module can be disposed on the inner or outer side wall of the storage box.

[0036] It should be noted that in some other embodiments, one or more magnetic field modules can also be provided within the storage compartment.

[0037] As Figures 2 to 3 shown, in one embodiment, the magnetic field module 200 includes a magnetic field member 210, a first grid frame 220, a second grid frame 230, and a locking member 240. The magnetic field member 210 is used to generate a magnetic field. The first grid frame 220 and the second grid frame 230 are respectively disposed on opposite sides of the magnetic field member 210 to clamp the magnetic field member 210. The locking member 240 fixes the first grid frame 220 and the second grid frame 230 together.

[0038] Specifically, when viewed as a whole, the first grid frame 220 and the second grid frame 230 can be simply regarded as a structure formed by connecting multiple longitudinal ribs and multiple transverse ribs. Adjacent two longitudinal ribs and adjacent two transverse ribs enclose a grid. The number and distribution positions of the longitudinal ribs and transverse ribs of the first grid frame 220 and the second grid frame 230 are all the same.

[0039] Referring to Figures 2 to 3 As shown, the magnetic field member 210 has a flat structure. After the magnetic field module 200 is assembled, the first grid frame 220 and the second grid frame 230 are respectively located on opposite sides of the magnetic field member 210, thereby clamping the magnetic field member 210. The locking member 240 includes eight clips, and the clips simultaneously clamp the first grid frame 220 and the second grid frame 230 to fix the first grid frame 220 and the second grid frame 230 together, so that the first grid frame 220 and the second grid frame 230 clamp the magnetic field member 210.

[0040] Specifically, two clips are respectively arranged on the four side edges of the first grid frame 220 and the second grid frame 230. The clips simultaneously clamp the grid ribs (the longitudinal ribs or transverse ribs mentioned above) at the edges of the first grid frame 220 and the second grid frame 230 along the distribution direction of the first grid frame 220 and the second grid frame 230, thereby clamping and fixing the first grid frame 220 and the second grid frame 230 in the distribution direction of the first grid frame 220 and the second grid frame 230, so that the first grid frame 220 and the second grid frame 230 cannot move away from each other, and thus are fixed at the position of clamping the magnetic field member 210.

[0041] In the solution of this embodiment, by respectively arranging the first grid frame 220 and the second grid frame 230 on opposite sides of the magnetic field member 210, so that the first grid frame 220 and the second grid frame 230 clamp the magnetic field member 210, and using the locking member 240 to fix the first grid frame 220 and the second grid frame 230 at the position of clamping the magnetic field member 210. When the magnetic field module 200 is installed in the refrigeration device, the first grid frame 220 and the second grid frame 230 can play a role in wrapping the magnetic field member 210, so that the first grid frame 220 and the second grid frame 230 can protect the magnetic field member 210 and reduce the occurrence of damage to the magnetic field member 210 caused by external collision. At the same time, the first grid frame 220 and the second grid frame 230 clamp the magnetic field member 210, making the magnetic field member 210 not easily deformed, and improving the structural stability of the magnetic field member 210. Moreover, the cost of using the grid frame to achieve protection and fixation is relatively low, and while playing the role of protection and fixation, the magnetic field member 210 can be directly observed, which is convenient for performing certain inspection work on the magnetic field member 210 without disassembly.

[0042] It should be noted that when the magnetic field module is installed in the refrigeration device, there are no special requirements for the relative positions of the first grid frame and the second grid frame. That is to say, when the magnetic field module is installed horizontally, the grid frame above can be the first grid frame or the grid frame below can be the first grid frame. When the magnetic field module is installed vertically, the grid frame on the left can be the first grid frame or the grid frame on the right can be the first grid frame.

[0043] It should be noted that the first grid frame and the second grid frame can be grid ribs made of only materials such as plastic or metal, or a coating can be added to the surface of the grid ribs.

[0044] It should be noted that in some other embodiments, the locking member can also include two, three or more clamping buckles, that is, at least two clamping buckles. And preferably, the multiple clamping buckles are arranged on at least the opposite sides of the first grid frame and the second grid frame.

[0045] It should be noted that in some other embodiments, the locking member can also be other integral structures, such as a magic tape that wraps around the first grid frame and the second grid frame at the same time, or the locking member can also be a split structure, with one part arranged on the first grid frame and the other part arranged on the second grid frame, so that the first grid frame and the second grid frame are fixed through the cooperation of the two parts of the locking member, such as a snap structure.

[0046] As Figures 2 to 5 shown, further, the magnetic field member 210 includes a permanent magnet plate 211 and a magnetic field homogenizing plate 212. The magnetic field homogenizing plate 212 is arranged in contact with the permanent magnet plate 211, and the area of the magnetic field homogenizing plate 212 is larger than that of the permanent magnet plate 211. In other words, the projection of the permanent magnet plate 211 on the surface of the magnetic field homogenizing plate 212 facing the permanent magnet plate 211 completely falls on the surface of the magnetic field homogenizing plate 212, and there is an area on the surface of the magnetic field homogenizing plate 212 that is not covered by the projection of the permanent magnet plate 211.

[0047] It should be noted that when the magnetic field module is installed in the refrigeration device, the permanent magnet plate faces the area for storing food materials. Combining Figure 1 shown, that is, the permanent magnet plate should face the drawer. That is, for the magnetic field module above the drawer, the permanent magnet plate is located below the magnetic field homogenizing plate, and for the magnetic field module below the drawer, the permanent magnet plate is located above the magnetic field homogenizing plate.

[0048] By arranging the permanent magnet plate 211 and the magnetic field homogenizing plate 212 so that the magnetic field homogenizing plate 212 is arranged in contact with the permanent magnet plate 211, the magnetic field homogenizing plate 212 can play a role in guiding and converging the magnetic field generated by the permanent magnet plate 211, which helps to concentrate the magnetic field generated by the permanent magnet plate 211 in the magnetic field preservation space, thereby improving the utilization rate of the magnetic field generated by the permanent magnet plate 211.

[0049] It should be noted that the magnetic field homogenizing plate and the permanent magnetic plate can be completely attached to each other, or there can be a certain gap between them.

[0050] It should be noted that in some other embodiments, the magnetic field structure can also only include the permanent magnetic plate and can also generate a magnetic field.

[0051] As Figures 2 to 6 shown, further, there are three mounting posts 221 provided on the grid ribs of the first grid frame 220, and the magnetic field component 210 is provided with mounting holes 213 that cooperate with the mounting posts 221 so that the mounting posts 221 are embedded in the mounting holes 213. Specifically, the mounting posts 221 protrude from the side of the first grid frame 220 facing the magnetic field component 210. When the first grid frame 220 and the magnetic field component 210 are assembled in place, the mounting posts 221 are embedded in the mounting holes 213. The mounting holes 213 of the magnetic field component 210 are the corresponding overlapping openings on the permanent magnetic plate 211 and the magnetic field homogenizing plate 212.

[0052] By providing the mounting posts 221 on the first grid frame 220 and the mounting holes 213 on the magnetic field component 210, when the magnetic field component 210 and the first grid frame 220 are assembled in place, the mounting posts 221 are embedded in the mounting holes 213. On the one hand, the mounting posts 221 and the mounting holes 213 can play a positioning role in the assembly of the magnetic field component 210 and the first grid frame 220, facilitating the assembly work of the first grid frame 220 and the magnetic field component 210. On the other hand, the embedding of the mounting posts 221 in the mounting holes 213 can play a role in restricting the relative movement of the magnetic field component 210 and the first grid frame 220 after being assembled in place, thereby improving the stability of the magnetic field component 210 and the first grid frame 220 after being assembled in place.

[0053] It should be noted that in some other embodiments, the number of the mounting posts can also be one, two or other numbers.

[0054] As Figures 2 to 7 shown, further, the length of the mounting posts 221 is greater than the distance between the first grid frame 220 and the second grid frame 230 after being assembled in place, and the grid rib part of the second grid frame 230 corresponding to the mounting posts 221 forms a bending part 231 to avoid the mounting posts 221. That is to say, when the magnetic field component 210, the first grid frame 220 and the second grid frame 230 are assembled in place, the mounting posts 221 can directly pass through the mounting holes 213 of the magnetic field component 210 and pass through the concave part of the bending part 231 of the second grid frame 230. In other words, if the second grid frame 230 does not have the bending part 231, then the mounting posts 221 will directly abut against the grid ribs of the second grid frame 230, resulting in the first grid frame 220 and the second grid frame 230 not being able to be assembled in place.

[0055] By making the length of the mounting post 221 greater than the distance between the first grid frame 220 and the second grid frame 230 after being assembled in place, and making the grid rib portion of the second grid frame 230 corresponding to the mounting post 221 form a bending portion 231, after the magnetic field member 210, the first grid frame 220 and the second grid frame 230 are assembled in place, the mounting post 221 can directly pass through the mounting hole 213 of the magnetic field member 210 and pass through the concave portion of the bending portion 231 of the second grid frame 230. That is to say, the magnetic field member 210, the first grid frame 220 and the second grid frame 230 can realize assembly positioning through the cooperation relationship among the mounting post 221, the mounting hole 213 and the bending portion 231, further improving the assembly convenience of the magnetic field module 200.

[0056] As Figures 2 to 7 shown, further, the set position of the mounting post 221 is offset from the center position of the first grid frame 220. Correspondingly, the mounting hole 213 of the magnetic field member 210 is also offset from the center position of the magnetic field member 210. Therefore, when the first grid frame 220 and the magnetic field member 210 are assembled, along the relative distribution direction of the first grid frame 220 and the magnetic field member 210, the magnetic field member 210 can be assembled in a uniquely determined direction to align the mounting post 221 and the mounting hole 213, so that the magnetic pole direction of the magnetic field member 210 is determined, which further helps to quickly confirm the distribution direction of the magnetic poles when arranging the magnetic field module 200 in the refrigerator and improves the convenience.

[0057] For example, assuming that the side of the magnetic field member 210 facing away from the first grid frame 220 is the N pole, the first grid frame 220 can be quickly confirmed via the mounting post 221, and then the magnetic pole direction of the magnetic field member 210 can be quickly confirmed.

[0058] As Figures 2 to 7 shown, in one embodiment, the permanent magnet plate 211 is integrally in the shape of a square with a corner missing, and the grids at the corners of the first grid frame 220 and the second grid frame 230 are provided with diagonal ribs (the first diagonal rib 222 and the second diagonal rib 232) to indicate the assembly direction of the missing corner portion of the permanent magnet plate 211. Specifically, the first diagonal rib 222 and the second diagonal rib 232 of the first grid frame 220 and the second grid frame 230 are the reinforcing ribs that intersect both the longitudinal ribs and the transverse ribs, and after the magnetic field module 200 is assembled in place, the inclination directions of the first diagonal rib 222 and the second diagonal rib 232 are the same as the inclination direction of the missing corner edge of the permanent magnet plate 211, so that the installation direction of the permanent magnet plate 211 can be determined by the cooperation between the permanent magnet plate 211 and the diagonal ribs, so that the magnetic pole direction of the magnetic field member 210 is determined, which plays an indicative role in the magnetic pole distribution of the permanent magnet plate 211, thus facilitating the subsequent assembly work based on the magnetic poles.

[0059] Referring to Figure 5As shown, the magnetic field homogenizing plate 212 can also be set in the shape of a square with a corner missing. Alternatively, in some other embodiments, the magnetic field homogenizing plate can also be set as a square.

[0060] In addition, a plastic sealing film is provided on the surfaces of the permanent magnetic plate 211 and the magnetic field homogenizing plate 212, thereby protecting the permanent magnetic plate 211 and the magnetic field homogenizing plate 212 and preventing excessive moisture from eroding the permanent magnetic plate 211 and the magnetic field homogenizing plate 212.

[0061] In some other embodiments, different identifiers can be set for the first grid frame and the second grid frame. For example, the first grid frame and the second grid frame have different colors, so as to quickly identify which side the permanent magnetic plate is on.

[0062] So far, 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 content 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 determined to cover all these other variations or modifications.
