[0002] It is now found that the magnetic field also has a certain impact on the fresh-keeping storage of food materials. The magnetic field is a physical field composed of energy, which affects the bonding and breaking of hydrogen bonds in water molecules, is conducive to the destruction of hydrogen bonds, and changes the clustering phenomenon of water molecules by promoting the phenomenon of water molecules clustering into large molecular clusters, forming smaller water molecular clusters or even single water molecules. Under the action of the magnetic field, the ice nuclei formed by small water molecular clusters or single water molecules are difficult to aggregate water molecules to grow orderly into large ice crystals, and appear in the form of micro ice crystals, which not only promotes the rapid passage of the freezing process through the phase change stage, but also reduces the damage of ice crystals to cells. Therefore, introducing a suitable magnetic field into the refrigerating and freezing storage device can help improve the fresh-keeping effect of food materials.

[0003] In the prior art, there is also a solution in which a magnetic field component is arranged in the storage compartment of a refrigerator to form a fresh-keeping storage space.

[0046] Those skilled in the art should understand that the embodiments described below are only part of the embodiments of the present utility model, rather than all of the embodiments of the present utility model. These part of the embodiments are intended to explain the technical principles of the present utility model, rather than to limit the protection scope of the present utility model.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0049] Furthermore, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. 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.

[0050] This embodiment provides a magnetic field module for a refrigerating and freezing storage device. The refrigerating and freezing device is a storage device including a refrigeration system, and a specific implementation form thereof is a refrigerator. The refrigeration system can be a common compression refrigeration system, which provides cooling capacity to the storage compartment in forms such as direct cooling and / or air cooling, so that the storage compartment has a desired preservation temperature. The magnetic field module is installed in the storage compartment, and by applying a magnetic field, the fresh-keeping effect is improved.

[0051] Figure 1 is a schematic diagram of a magnetic field module 140 for a refrigerating and freezing storage device according to an embodiment of the present utility model, Figure 2 isFigure 1 Exploded view of the components of the magnetic field module 140 in the refrigerating and freezing storage device shown. Generally, the magnetic field module 140 may include: a packaging housing and a magnetic field component. An installation space is defined inside the packaging housing; the overall shape of the magnetic field component is plate-shaped and is installed in the installation space formed by the packaging housing. As the component for forming the magnetic field, the magnetic field component is protected by the packaging housing to avoid corrosion and damage, and can also avoid contamination caused by contact with food residues.

[0052] Generally, the magnetic field component may include: a magnetic source member 143 and a magnetic conduction plate 142. The magnetic source member 143 is disposed in the installation space and is used to generate a magnetic field. The magnetic source member 143 may be a permanent magnet sheet with uniform magnetization. For example, the permanent magnet sheet may be made of a permanent magnetic material with a certain flexibility. For example, a flexible rubber magnetic sheet made by compounding bonded ferrite magnetic powder and synthetic rubber and through a calendering forming process may be used.

[0053] The magnetic conduction plate 142 is disposed in the installation space and is arranged in contact with the magnetic source member 143, and is used to adjust the magnetic field distribution of the magnetic source member 143. The magnetic conduction plate 142 is made of a material with low coercivity and high magnetic permeability, and its area may be slightly larger than that of the magnetic source member 143. The close fit between the magnetic conduction plate 142 and the magnetic source member 143 can achieve a zero-gap fit, improving the uniformity of the magnetic field. Through testing, the magnetic conduction plate 142 can make the magnetic field more uniform and expand the coverage range of the magnetic field.

[0054] The packaging housing is constructed such that the installation space ensures that the magnetic source member 143 is closer to the fresh-keeping storage space relative to the magnetic conduction plate 142. That is, after the magnetic field module is installed in the refrigerating and freezing storage device, the side of the magnetic source member 143 opposite to the magnetic conduction plate 142 faces the magnetic field fresh-keeping space and is closer to the magnetic field fresh-keeping space than the magnetic conduction plate 142. In view of the characteristic that the magnetic field strength gradually decays with distance, improvements are made to make full use of the magnetic field released by the magnetic source member 143.

[0055] The magnetic field module 140 includes, from the outside to the inside in the order relative to the fresh-keeping storage space: a first housing 141, a magnetic conduction plate 142, a magnetic source member 143, and a second housing 144. The second housing 144 is buckled with the first housing 141 (it can also be said that the second housing 144 covers the first housing 141), and together they define a space for accommodating the magnetic conduction plate 142 and the magnetic source member 143.

[0056] In the embodiment where the magnetic field module 140 is arranged above the magnetic field fresh-keeping space, the first housing 141 may be the upper half of the packaging housing of the magnetic field module 140, and the second housing 144 may be the lower half of the packaging housing of the magnetic field module 140.

[0057] The contour defined by the positioning component is adapted to the outer shape of the magnetic field component, and is used to define the position of the magnetic field component in the installation space. The positioning component may include a first positioning structure 172 for fixing the magnetic conduction plate 142 and a second positioning structure 171 for fixing the magnetic source member 143. The first positioning structure 172 and the second positioning structure 171 jointly maintain the relative positions of the magnetic conduction plate 142 and the magnetic source member 143.

[0058] Figure 3 FIG. 4 is a schematic view of the first housing 141 in the magnetic field module 140 for a refrigerating and freezing storage device according to an embodiment of the present invention and a partial enlarged view thereof; Figure 4 FIG. 6 is a schematic view of the second housing 144 of the magnetic field module 140 in the refrigerating and freezing storage device 10 having a magnetic field module according to an embodiment of the present invention and a partial enlarged view thereof; Figure 5 FIG. 8 is a schematic view of the state of the first housing 141 in the magnetic field module 140 for a refrigerating and freezing storage device according to an embodiment of the present invention after installing the magnetic source member 143 and the magnetic conduction plate 142 and a partial enlarged view thereof.

[0059] The encapsulation housing may include: a first housing 141 and a second housing 144. The first housing 141 includes a first panel 1412 and a first side wall 1413 provided at the edge of the first panel 1412. The first panel 1412 abuts against one side of the magnetic source member 143; and the first positioning structure 172 and the second positioning structure 171 are respectively provided on the wall surface of the first panel 1412 that abuts against the magnetic conduction plate 142, that is, the inner surface of the first panel 1412.

[0060] The first positioning structure 172 includes positioning ribs protruding from the wall surface. The shape formed by the positioning ribs and / or the extension lines of the positioning ribs is adapted to the outer peripheral contour of the magnetic conduction plate 142, so as to define the magnetic conduction plate 142 within the area surrounded by the positioning ribs and / or the extension lines of the positioning ribs. That is, after the magnetic conduction plate 142 is installed, it is snapped into the area defined by the positioning ribs. When the size of the magnetic conduction plate 142 is larger than that of the magnetic source member 143, the magnetic conduction plate 142 has an extended area on the outer periphery of the area where it abuts against the magnetic source member 143.

[0061] The second positioning structure 171 includes a protruding portion extending from the positioning rib towards the central region of the wall surface. A positioning notch is provided at a position corresponding to the protruding portion in the outer extension region of the magnetic conduction plate 142, and the protruding length of the protruding portion matches the width of the outer extension region, so that the end of the protruding portion abuts against the magnetic source member 143 to achieve the positioning of the magnetic source member 143. The magnetic source member 143 and the magnetic conduction plate 142 are respectively square, and one or more protruding portions are respectively provided on multiple side edges of the positioning rib. That is, the second positioning structure 171 is arranged at the notch position of the magnetic conduction plate 142. After the magnetic source member 143 is installed, it is snapped into the region defined by the second positioning structure 171. The protruding portion can be a structure protruding towards the middle relative to the positioning rib and / or the extension line of the positioning rib formed by a rib or a similar structure.

[0062] The magnetic source member 143 and the magnetic conduction plate 142 are respectively square, and one or more protruding portions are respectively provided on multiple side edges of the positioning rib. In some embodiments, by adjusting the position and protruding length of the protruding portion, the direction of the magnetic source member 143 can also be defined. Therefore, the above-mentioned first positioning structure 172 and second positioning structure 171 can ensure that the magnetic conduction plate 142 and the magnetic source member 143 are installed in the correct manner without being installed backwards or wrongly.

[0063] In some embodiments, the magnetic source member 143 and the magnetic conduction plate 142 can also be respectively square with one vertex angle missing, and the position of the missing angle is used to define the orientation of the magnetic source member 143 and the magnetic conduction plate 142, which is convenient for the assembler to operate.

[0064] The first housing 141 and the second housing 144 can also be respectively provided with a plurality of mutually cooperating circumferential connection portions 163, 164, and the middle portions of the first housing 141 and the second housing 144 are also respectively provided with mutually cooperating middle limiting structures 161, 162.

[0065] In the embodiment where the magnetic field module 140 is set as a square plate, the circumferential connection portions 163, 164 include a snap connection structure and / or a screw connection structure provided at positions adjacent to each side wall of the first housing 141 and the second housing 144. Snap holes 164 are provided at positions near the edges of the four sides of the first housing 141, and a snap connection structure of claws 163 cooperating with the snap holes 164 is provided at positions near the edges of the four sides of the second housing 144. That is, the circumferential connection portion includes the snap holes 164 and the claws 163 cooperating therewith. Those skilled in the art can set various types of snap connection structures according to specific fixed connection requirements. The circumferential connection portions 163, 164 can ensure the reliable connection and fixation of the circumference of the magnetic field module 140, and can reliably press the four sides of the magnetic source member 143 and the magnetic conduction plate 142.

[0066] The magnetic field module 140 is long-term set in the low-temperature operating environment of refrigeration and freezing. Relying solely on the peripheral connecting parts 163 and 164 cannot ensure that the encapsulation housing can tightly press the magnetic source part 143 and the magnetic conduction plate 142 as a whole. This may cause local hollowing, thereby avoiding an increase in magnetic resistance in local areas and resulting in uneven magnetic fields.

[0067] In the field of magnetic fields, those skilled in the art generally believe that ensuring a uniform distribution of the magnetic field requires ensuring the integrity of the plate surface of the magnetic source part. However, in the magnetic field module 140 of this embodiment, the inventor creatively realized that when the magnetic source part 143 and the magnetic conduction plate 142 are arranged simultaneously, the flatness of their fit has a greater impact on the magnetic field uniformity. In response to this situation, the inventor also tried to use an adhesive to paste the magnetic source part 143 and the magnetic conduction plate 142, but the thickness of the adhesive is difficult to control, and it will age after long-term use, and it is also difficult to achieve a flat fit between the magnetic source part 143 and the magnetic conduction plate 142.

[0068] Based on the above problems, this embodiment provides a middle limiting structure that also cooperates with each other in the middle of the first housing 141 and the middle of the second housing 144. The middle limiting structure may include: a first limiting part 161 and a second limiting part 162. The first limiting part 161 is arranged on the inner surface of the first housing 141 and extends towards the second housing 144. The second limiting part 162 is arranged at a position opposite to the first limiting part 161 on the inner surface of the second housing 144, and the first limiting part 161 and the second limiting part 162 may be arranged to be connected through a buckle structure to limit the distance from the inner surface of the first housing 141 to the inner surface of the second housing 144. That is to say, the inner middle parts of the first housing 141 and the second housing 144 extend relatively, cooperate with each other, and are connected through a buckle structure at the ends. Through holes are provided at positions corresponding to the respective middle limiting structures on the magnetic source part 143 and the magnetic conduction plate 142 for the middle limiting structure to pass through. The middle limiting structure can press the central regions of the magnetic source part 143 and the magnetic conduction plate 142, and cooperate with the peripheral connecting parts 163 and 164 to achieve an overall tight fit between the magnetic source part 143 and the magnetic conduction plate 142.

[0069] Support ribs 181 are respectively arranged in the regions of the inner surface of the first housing 141 of the magnetic field module 140 opposite to the magnetic conduction plate 142, and support ribs 181 are also arranged in the regions of the inner surface of the second housing 144 opposite to the magnetic source part 143. Thus, the support ribs 181 are used to abut against the magnetic conduction plate 142 and the magnetic source part 14, so that the magnetic conduction plate 142 and the magnetic source part 143 are tightly fitted.

[0070] The support ribs 181 can be arranged in a ring shape around the middle limiting structures 161 and 162, and the minimum distance between adjacent support ribs 181 is set to be less than the sum of the thicknesses of the magnetic conduction plate 142 and the magnetic source part 143. That is, by restricting the density of the support ribs 181, it is ensured that there will be no hollowing at the positions of the spaces between the support ribs 181. The width of the top surface of the support rib 181 (as the contact surface against the magnetic conduction plate 142 or the magnetic source part 143) is set to be greater than the sum of the thicknesses of the magnetic conduction plate 142 and the magnetic source part 143. The support ribs 181 can also improve the structural strength of the packaging shell, and cooperate with the peripheral connection parts 163 and 164 and the middle limiting structures 161 and 162 to achieve the long-term stability of the structure. The above-mentioned minimum distance between the support ribs 181 and the width of the top surface of the support rib 181 are improvements made by the inventor through in-depth research on the structures and material characteristics of the magnetic conduction plate 142 and the magnetic source part 143. After physical verification of the samples, an effect beyond expectations is obtained, far exceeding the fitting effect when the magnetic conduction plate 142 or the magnetic source part 143 is in plane contact.

[0071] Thus, the self-construction of the support ribs 181 and their positions relative to each other are set according to the conditions of the magnetic conduction plate 142 and the magnetic source part 143. On the one hand, the structural strength and stability are improved, and on the other hand, it can also ensure the reliable fitting of the magnetic conduction plate 142 and the magnetic source part 143.

[0072] The installation process of the above magnetic field module 140 is as follows: arrange the inner side of the first housing 141 upward; embed the magnetic conduction plate 142 into the first positioning structure 172 on the inner surface of the first panel 1412 of the first housing 141, and then arrange the magnetic source part 143 on the magnetic conduction plate 142, cooperate with the second positioning structure 171 on the inner surface of the first panel 1412, and fasten the second housing 144 to the first housing 141 to make the peripheral connection parts 163 and 164 and the middle limiting structures 161 and 162 be reliably connected. Finally, turn the whole over to obtain the magnetic field module 140.

[0073] Figure 6 is a schematic diagram of the magnetic field module 140 for a refrigerating and freezing storage device according to another embodiment of the present invention. Figure 7 is Figure 6 is an exploded view of the components of the magnetic field module 140 in the refrigerating and freezing storage device shown. This embodiment of the magnetic field module provides another fixed connection structure for the magnetic field module 140. A plurality of screw posts protrude from the inner side of the first housing 141 and serve as the middle limiting structures and the peripheral connection parts respectively. A plurality of screw holes are provided on the second housing 144, and the screws 145 pass through the screw holes and the screw posts to realize the connection and fixation of the first housing 141 and the second housing 144 and the height limitation.

[0074] For example, when implementing the middle limiting structure by using a screw connection structure, the screw post can be arranged on the inner surface of the first housing 141 or the second housing 144. The connecting screw is connected to the screw post from the other side opposite to the screw post to define the distance from the inner surface of the first housing 141 to the inner surface of the second housing 144. Similarly, by arranging screw posts at positions near the edge of the magnetic field module 140 and using connecting screws for connection, a circumferential connecting portion can also be realized.

[0075] This embodiment also provides a refrigerating and freezing storage device 10. Figure 8 FIG. 1 is a schematic diagram of a refrigerating and freezing storage device 10 according to an embodiment of the present invention. Figure 9 FIG. 2 is a schematic diagram of a box body 12 portion for setting a fresh-keeping storage space in a refrigerating and freezing storage device 10 according to an embodiment of the present invention.

Figure 11 FIG. 4 is a schematic diagram of the installation state of a magnetic field module 140 in a refrigerating and freezing storage device 10 according to an embodiment of the present invention.

[0076] The refrigerating and freezing storage device 10 of this embodiment generally may include a box body 12, a door body 11, and a refrigeration system (not shown in the figure). At least one front-side open storage compartment 121 can be defined inside the box body 12, usually multiple, such as a refrigerating storage compartment, a freezing 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 8 The shown refrigerating and freezing storage device 10 of a cross-over double-door refrigerator is only an example, and those skilled in the art can configure the specific number, functions, and layout modes of the storage compartments according to requirements. The storage compartment 121 can be spatially divided by means of a shelf, a shelf board, a drawer, etc. to achieve corresponding storage functions, such as chilled storage, frozen storage, dry storage, etc. In some embodiments, one or more fresh-keeping storage containers 123 can be arranged inside the storage compartment 121. The freshness preservation storage effect is improved by applying a magnetic field inside the fresh-keeping storage container 123.

[0077] The fresh-keeping storage container 123 is arranged inside the storage compartment 121 and can be a drawer-type storage container or a storage container with other structures. A magnetic field module 140 is arranged inside or outside or on the side wall of the fresh-keeping storage container 123.

Both sides of the magnetic field module 140 are respectively installed on the magnetic field installation structures 310 for generating a magnetic field that promotes the formation of a fresh-keeping storage environment. In some embodiments, the magnetic field installation structure 310 is directly provided on the side wall of the inner box or the vertical partition of the box, that is, directly formed on the side wall of the storage compartment 121. In other embodiments, when the fresh-keeping storage container 123 is a drawer-type storage container, the magnetic field installation structure 310 can also be provided on the storage drawer slide rail device installed on the side wall of the inner box or the vertical partition of the box; that is, the magnetic field installation structure 310 is formed on the storage drawer slide rail device.

[0079] The magnetic field installation structure 310 may include: a chute 312 and a limiting component. The chute 312 can be arranged along the front-back direction of the box 12, and the side part of the magnetic field module 140 is slidably arranged in the chute 312. That is, the chute 312 has an opening facing the inside of the storage compartment 121, and both side edges of the magnetic field module 140 are arranged in the chute 312. The limiting component is arranged on the bottom wall and / or the side wall of the chute 312, and limits the position of the magnetic field module 140 relative to the chute 312 by abutting against the magnetic field module 140. When needed, the user can remove the magnetic field module 140 for cleaning.

[0080] The limiting component may include: a first limiting member 311, a second limiting member 312, and a limiting rib 313, to achieve the limiting of the magnetic field module 140 in multiple directions and ensure the correct installation position of the magnetic field module 140. The first limiting member 311 is arranged on the bottom wall of the chute 312 for abutting against the side of the magnetic field module 140. The first limiting member 311 may have a guiding surface that gradually protrudes towards the magnetic field module 140 from front to back, so as to gradually generate elastic deformation during the insertion process of the magnetic field module 140. That is, the guiding surface of the first limiting member 311 is inclined inwards from front to back, reducing the resistance during the insertion process of the magnetic field module 140, and applying a limiting pressure from both sides after the magnetic field module 140 is installed in place.

[0081] In some embodiments, a plurality of first limiting members 311 are arranged in each chute 312. The plurality of first limiting members 311 are arranged at intervals along the front-back direction of the chute 312, applying a more uniform limiting pressure. Figure 11 An embodiment with two first limiting members 311 at the front and back is shown, and those skilled in the art can, on this basis, set a greater number of first limiting members 311.

[0082] The second limiting member 312 is disposed on the upper groove sidewall of the sliding groove 312 and is used to abut against the magnetic field module 140 from the top of the magnetic field module 140. A limiting notch 1411 is further provided at a position on the top wall of the magnetic field module 140 near the side corresponding to the second limiting member 312, and is configured such that the magnetic field module 140 is installed in the magnetic field installation structure 312 and then the second limiting member 312 is received to achieve limiting. The second limiting member 312 may have a guiding surface that gradually protrudes downward and obliquely from front to back, so that elastic deformation gradually occurs during the insertion of the magnetic field module 140 and finally engages with the limiting notch 1411.

[0083] The sliding groove 312 is further provided with a limiting rib 313 at the rear end, and the limiting rib 313 is used to abut against the rear side of the magnetic field module 140, thereby limiting the front and rear positions of the magnetic field module 140.

[0084] The limiting components on both sides of the magnetic field module 140 can be symmetrically arranged. If the magnetic field module 140 is inserted incorrectly or is inserted in the reverse direction itself, then it will be resisted or restricted by the limiting components, reminding the installer to adjust the installation method in a timely manner.

[0085] 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 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 recognized as covering all these other variations or modifications.
