Description

Technical Field

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

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

[0032] 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, typically 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 pre-set requirements. Figure 1 The refrigeration device 1 shown 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 modules 200 are disposed within the storage compartment 101 to generate a magnetic field within the storage compartment 101.

[0033] 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.

[0034] 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. Additionally, the space within the storage compartment can also be partitioned by means of shelves, boards, etc. to achieve the corresponding function of storing food ingredients. Or, food ingredients can also be stored by providing storage boxes within the storage compartment, and the magnetic field module can be disposed on the inner or outer side wall of the storage box.

[0035] It should be noted that in some other embodiments, one or more magnetic field modules can also be provided within the storage compartment.

[0036] As Figures 2 to 4 shown, the magnetic field module 200 includes a magnetic field structure 210, a first housing 220, and a second housing 230. The magnetic field structure 210 is used to generate a magnetic field. The first housing 220 is pivotally connected to the second housing 230, and the second housing 230 and the first housing 220 have a closed position where they are mutually latched to clamp the magnetic field structure 210, so as to reach the closed position and disengage from the closed position by relative rotation of the first housing 220 and the second housing 230.

[0037] As Figures 2 to 4As shown, further, the magnetic field module 200 also includes a connecting rod 240, and the first shell 220 and the second shell 230 are pivotally connected via the connecting rod 240. Specifically, the first shell 220 and the second shell 230 are both plate shell structures with square outer edge shapes, and the outer edge shapes of the first shell 220 and the second shell 230 are roughly the same in size. An axial hole (not marked in the figure) is formed at one side of the first shell 220, and the axial hole extends in the same direction as the side extension direction of the first shell 220. Similarly, an axial hole (not marked in the figure) is also formed at one side of the second shell 230, and the axial hole extends in the same direction as the side extension direction of the second shell 230.

[0038] The first shell 220 is provided with a side with an axial hole and the second shell 230 is provided with a side with an axial hole, and the axial hole of the first shell 220 is coaxially arranged with the axial hole of the second shell 230. The connecting rod 240 passes through the axial hole of the first shell 220 and the axial hole of the second shell 230 at the same time, so that the first shell 220 and the second shell 230 can rotate around the connecting rod 240 while connecting the first shell 220 and the second shell 230 together.

[0039] The first housing 220 and the second housing 230 can rotate around the connecting rod 240, that is, the side of the first housing 220 opposite to the side where the connecting rod 240 is located and the side of the second housing 230 opposite to the side where the connecting rod 240 is located can be farther away or closer as the first housing 220 and the second housing 230 rotate relative to each other. When the side of the first housing 220 opposite to the side where the connecting rod 240 is located and the side of the second housing 230 opposite to the side where the connecting rod 240 is located are closest, that is, the first housing 220 and the second housing 230 are in a closed position, the first housing 220 and the second housing 230 clamp the magnetic field structure 210 therebetween.

[0040] Accordingly, by making the first shell 220 and the second shell 230 rotate relative to each other, the side of the first shell 220 opposite to the side where the connecting rod 240 is located and the side of the second shell 230 opposite to the side where the connecting rod 240 is located can be made to have a greater distance, that is, to be out of the closed position, so that the magnetic field structure 210 can be taken and placed through the gap between the first shell 220 and the second shell 230.

[0041] In the solution of this embodiment, by pivotally connecting the first housing 220 and the second housing 230, the first housing 220 and the second housing 230 can reach the closed position where they are engaged with each other to clamp the magnetic field structure 210 and the disengaged closed position through relative rotation. When the magnetic field module 200 is installed in the refrigeration device 1, the first housing 220 and the second housing 230 are in the closed position to clamp the magnetic field structure 210, that is, the magnetic field structure 210 is wrapped between the two, so that the first housing 220 and the second housing 230 can protect the magnetic field structure 210 and reduce the occurrence of damage to the magnetic field structure 210 caused by external collisions. At the same time, the first housing 220 and the second housing 230 clamp the magnetic field structure 210, making the magnetic field structure 210 not easily deformed and improving the structural stability of the magnetic field structure 210. Moreover, the first housing 220 and the second housing 230 can rotate relative to each other to reach the closed position and the disengaged closed position, making the assembly between the magnetic field structure 210 and the first housing 220 and the second housing 230 very convenient.

[0042] It should be noted that in some other embodiments, the connecting rod may not be provided. Instead, a circular rod-shaped structure is integrally formed on one of the first housing and the second housing, and an axially-hole structure with a side opening is integrally formed on the other, so that the first housing and the second housing are pivotally connected by clamping the circular rod-shaped structure through the axially-hole structure. Or, a circular rod-shaped structure is integrally formed on one of the first housing and the second housing, and an axially-hole structure is integrally formed on the other, so that the first housing and the second housing are pivotally connected by inserting the circular rod-shaped structure into the axially-hole structure.

[0043] As Figures 2 to 4 shown, the first housing 220 is provided with a first locking structure 221, and the second housing 230 is provided with a second locking structure 231. The first locking structure 221 and the second locking structure 231 cooperate with each other to fix the first housing 220 and the second housing 230 in the closed position. Specifically, the first locking structure 221 is a convex structure, and the second locking structure 231 is a hole structure. The convex structure is locked by being inserted into the hole structure.

[0044] Specifically, the convex structure (the first locking structure 221) is disposed on the side of the first housing 220 opposite to the side where the connecting rod 240 is located, and protrudes from the first housing 220 in a direction away from the position where the connecting rod 240 is located. Correspondingly, the hole structure (the second locking structure 231) is disposed on the side of the second housing 230 opposite to the side where the connecting rod 240 is located. Specifically, the side of the second housing 230 opposite to the side where the connecting rod 240 is located forms a protruding structure protruding in the direction towards the first housing 220, and a hole pointing to the position where the connecting rod 240 is located is formed on the protruding structure.

[0045] When the first housing 220 and the second housing 230 are in the closed position, the convex structure is embedded in the hole structure, and the convex structure and the hole structure form an abutment, thereby restricting the rotation of the first housing 220 and the second housing 230 that causes the first housing 220 and the second housing 230 to move away from each other without external interference, that is, restricting the first housing 220 and the second housing 230 from disengaging from the closed position, that is, fixing them in the closed position.

[0046] By providing a first locking structure 221 on the first housing 220 and a second locking structure 231 on the second housing 230, the first locking structure 221 and the second locking structure 231 can cooperate with each other to fix the first housing 220 and the second housing 230 in the closed position, so that the first housing 220 and the second housing 230 are more stable in the closed position, avoiding the situation that the magnetic field structure 210 falls out due to the accidental automatic disengagement of the first housing 220 and the second housing 230.

[0047] Preferably, the convex structure is also provided with an inclined surface, so that the hole structure can more easily cross the convex structure.

[0048] It should be noted that in some other embodiments, the first locking structure and the second locking structure can also be other structures that can cooperate with each other to achieve fixation, such as a magnetic attraction structure, a magic tape structure or a snap structure, etc.

[0049] In addition, it should be noted that in some other embodiments, the first locking structure and the second locking structure may not be provided, but the first housing or the second housing may be made slightly heavier so that it plays a certain pressing role by gravity.

[0050] As Figures 2 to 6 shown, further, the magnetic field structure 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. The permanent magnet plate 211 can be flexible, for example, a rubber magnetic sheet made of a composite of bonded ferrite magnetic powder and synthetic rubber through a calendering process. In other words, the permanent magnet plate 211 is arranged on the side of the magnetic field homogenizing plate 212 facing away from the first housing 220, and 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.

[0051] It should be noted that when the magnetic field module is arranged in the refrigeration equipment, the permanent magnet plate faces the area where the food ingredients are stored. As shown in Figure 1 combination, 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.

[0052] By arranging the permanent magnet plate 211 and the magnetic field homogenizing plate 212 such that the magnetic field homogenizing plate 212 is in abutting contact with the permanent magnet plate 211, the magnetic field homogenizing plate 212 can guide and converge the magnetic field generated by the permanent magnet plate 211, which helps to concentrate the magnetic field generated by the permanent magnet plate 211 within the magnetic field preservation space, thereby improving the utilization rate of the magnetic field generated by the permanent magnet plate 211.

[0053] It should be noted that the magnetic field homogenizing plate and the permanent magnet plate can be arranged in complete fit or with a certain gap.

[0054] It should be noted that in some other embodiments, the magnetic field structure can also include only the permanent magnet plate and can also generate a magnetic field.

[0055] As Figures 2 to 5 shown, further, a protruding first positioning rib 222 is provided on the side of the first housing 220 facing the magnetic field structure 210. The first positioning rib 222 is used to define an installation area that matches the outer shape of the permanent magnet plate 211. Specifically, the first positioning rib 222 is a continuous protruding rib formed on the side surface of the first housing 220 facing the magnetic field structure 210. The shape of the installation area surrounded by the first positioning rib 222 is the same as the outer edge shape of the permanent magnet plate 211. That is to say, the permanent magnet plate 211 can be placed within the installation area surrounded by the first positioning rib 222 and is surrounded by the first positioning rib 222.

[0056] By providing the first positioning rib 222 on the first housing 220 and using the first positioning rib 222 to define an installation area that matches the outer shape of the permanent magnet plate 211, the installation area can be used to position the installation of the permanent magnet plate 211, and the first positioning rib 222 can fasten the permanent magnet plate 211, making the installation of the permanent magnet plate 211 more stable.

[0057] It should be noted that in some other embodiments, the first positioning rib may not be continuous but a plurality of spaced positioning ribs, and the connection lines of the plurality of positioning ribs enclose an installation area with the same shape as the outer edge shape of the permanent magnet plate.

[0058] Continue to refer to Figures 2 to 5As shown, further, a side of the first housing 220 facing the magnetic field structure 210 is provided with a raised second positioning rib 223, and the second positioning rib 223 is used to define a mounting area that matches the shape of the shim plate 212, and the raised height of the second positioning rib 223 is greater than the raised height of the first positioning rib 222. Specifically, the second positioning rib 223 is a continuous raised rib formed on the side of the first housing 220 facing the magnetic field structure 210, and the shape of the mounting area surrounded by the second positioning rib 223 is the same as the shape of the outer edge of the shim plate 212, that is, the shim plate 212 can be placed in the mounting area surrounded by the second positioning rib 223 and surrounded by the second positioning rib 223.

[0059] Because the area of ​​the uniform magnetic plate 212 is larger than that of the permanent magnetic plate 211, and the permanent magnetic plate 211 is arranged on the side of the uniform magnetic plate 212 away from the first shell 220, the protruding height of the second positioning rib 223 is greater than the protruding height of the first positioning rib 222, that is, after being installed in place, the uniform magnetic plate 212 covers the permanent magnetic plate 211 and the first positioning rib 222.

[0060] By setting a second positioning rib 223 in the first shell 220, the second positioning rib 223 is used to define an installation area that matches the shape of the uniform magnetic plate 212, so that the installation area can be used to position the installation of the uniform magnetic plate 212, and the second positioning rib 223 can fasten the uniform magnetic plate 212, so that the installation of the permanent uniform magnetic plate 212 is more stable.

[0061] Preferably, the protruding height of the first positioning rib 222 is equal to the thickness of the permanent magnet plate 211 , so that the first positioning rib 222 can also support the shim plate 212 .

[0062] Reference Figures 2 to 5 As shown, during the assembly process of the magnetic field module 200, the permanent magnetic plate 211 is first placed in the area surrounded by the first positioning rib 222, and then the uniform magnetic plate 212 is placed in the area surrounded by the second positioning rib 223, and the uniform magnetic plate 212 covers the permanent magnetic plate 211. Then, the first housing 220 and the second housing 230 are relatively rotated to a closed position, so that the convex structure and the hole structure are locked together to complete the assembly. Then, it can be installed in the refrigeration equipment.

[0063] It should be noted that when the magnetic field module is arranged in the refrigeration device, there is no special requirement for the relative position of the first shell and the second shell, that is, when the magnetic field module is installed horizontally, the upper shell can be the first shell or the lower shell can be the first shell. When the magnetic field module is installed vertically, the left shell can be the first shell or the right shell can be the first shell.

[0064] like Figures 2 to 6As shown, the permanent magnet plate 211 is generally in the shape of a square with a corner missing. That is to say, the overall shape of the permanent magnet plate 211 is formed by cutting off a triangle at a corner of the square. Correspondingly, the first positioning rib 222 defines an installation area that matches the outer shape of the permanent magnet plate 211. That is, the shape of the installation area defined by the first positioning rib 222 is also in the shape of a square with a corner missing. In this way, the permanent magnet plate 211 has a uniquely determined placement direction in the first housing 220, thus playing an indicating role in the installation of the permanent magnet plate 211.

[0065] By making the permanent magnet plate 211 generally in the shape of a square with a corner missing, the missing corner part of the permanent magnet plate 211 can be used to indicate the installation direction of the permanent magnet plate 211, facilitating the determination of the installation direction of the permanent magnet plate 211, so that the magnetic pole direction of the permanent magnet plate 211 after being installed in place is determined, ensuring the correctness of the magnetic pole direction. Moreover, adopting the shape of a square with a corner missing has less influence on the overall magnetic field of the permanent magnet plate 211.

[0066] Refer to Figure 6 As 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.

[0067] It should be noted that in some other embodiments, instead of setting the first positioning rib to match the shape of the permanent magnet plate to determine the installation direction of the permanent magnet plate, the first housing is provided with an indicating mark to use the indicating mark to indicate the position of the missing corner of the permanent magnet plate. For example, an indicating arrow is set at a corner of the first housing to indicate that the missing corner part of the permanent magnet plate needs to be correspondingly set with the corner of the first housing where the indicating arrow is set.

[0068] In addition, in some other embodiments, the first housing and the second housing can be provided with different marks. For example, the first housing and the second housing have different colors to facilitate identifying which side the permanent magnet plate is on.

[0069] In some embodiments, the surfaces of the permanent magnet plate 211 and the magnetic field homogenizing plate 212 are provided with plastic sealing films, thereby protecting the permanent magnet plate 211 and the magnetic field homogenizing plate 212 and preventing excessive moisture from eroding the permanent magnet plate 211 and the magnetic field homogenizing plate 212.

[0070] As Figures 2 to 5 shown, both the first housing 220 and the second housing 230 are provided with hollowed-out areas, thereby facilitating direct observation of the magnetic field structure 210 through the hollowed-out areas, and facilitating inspection of whether there is a problem with the magnetic field structure 210 without disassembly.

[0071] It should be noted that in some other embodiments, the hollowed-out area may not be provided, and instead, the first outer shell or the second outer shell may be made of a transparent material. Additionally, in some other embodiments, the first outer shell and the second outer shell may not have a hollowed-out area and may not be made of a transparent material.

[0072] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present utility model have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present utility model can still be directly determined or derived based on the content disclosed in the present utility model without departing from the spirit and scope of the present utility model. Therefore, the scope of the present utility model should be understood and determined to cover all such other variations or modifications.
