Description

TECHNICAL FIELD

[0001] The present application relates to the field of cold storage technology, in particular to a cold storage and freezing storage device with a magnetic field module. BACKGROUND

[0002] The preservation storage effect of household refrigeration and freezing equipment such as refrigerators becomes an important indicator to measure the performance of such equipment. Fresh meat, fish and shrimp food, during storage, is prone to have problems such as taste deterioration and color darkening due to juice loss.

[0003] The conventional cold storage and freezing storage device mainly relies on precise temperature control and accelerated refrigeration speed or reduced storage temperature (deep cooling) to improve the preservation effect of food. These preservation and storage methods by temperature have high cost and complex control means. In recent years, the technical personnel in the field have also actively tried to use other preservation and storage technologies.

[0004] It has been found that a magnetic field has a certain influence on the preservation and storage of food. The magnetic field is a physical field of energy, which has an influence on the hydrogen bond combination and rupture in water molecules, is conducive to the destruction of hydrogen bonds, makes the water molecules form large molecular groups, changes the water cluster phenomenon, forms smaller water molecular groups, and even produces single water molecules. Under the action of the magnetic field, the ice nuclei formed by small water molecular groups or single water molecules are difficult to gather water molecules to grow into large ice crystals in an orderly manner, 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 food cells. Therefore, introducing a suitable magnetic field into the cold storage and freezing storage device can improve the preservation and storage effect of food.

[0005] However, the prior art arranges the magnetic field component inside the cold storage and freezing device for a long time, which is easily affected by low temperature, humidity, food residues, etc., and the surface is easily corroded and damaged, resulting in a decrease in the reliability of the magnetic field component.

[0058] Those skilled in the art should understand that the embodiments described below are merely a part of the embodiments of the present invention, and not all of the embodiments of the present invention. These partial embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0059] In the description of this embodiment, it should be understood that the terms "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," and "bottom," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this embodiment and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. For example, unless otherwise explicitly defined, for a refrigerator-type refrigeration and freezing device, the direction of the cabinet towards the door is front, the direction relative to the door towards the cabinet is rear, the direction towards the supporting ground is down, and the direction opposite to the ground is up.

[0060] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0061] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. Those skilled in the art can understand the specific meaning of these terms in this invention according to the specific circumstances.

[0062] This embodiment provides a refrigerated and frozen storage device with a magnetic field module. This refrigerated and frozen device is a storage device including a refrigeration system, one specific implementation of which is a refrigerator. The refrigeration system can be a common compression refrigeration system, which provides cooling to the storage compartment through, for example, direct cooling and / or air cooling, to maintain the desired storage temperature in the storage compartment.

[0063] Figure 1 This is a schematic diagram of a refrigerated and frozen storage device 10 with a magnetic field module according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the housing 12 portion of a refrigerated and frozen storage device 10 with a magnetic field module according to an embodiment of the present invention, which has a preservation storage space.

[0064] The refrigerated and frozen storage device 10 of this embodiment generally includes a cabinet 12, a door 11, and a refrigeration system (not shown in the figure). The cabinet 12 may define at least one front-opening storage compartment 121, and usually multiple compartments, such as a refrigerated storage compartment, a frozen storage compartment, a variable temperature storage compartment, etc. The specific number and function of the storage compartments can be configured according to pre-defined needs. Figure 1 The illustrated French door refrigerator's refrigeration and freezing storage unit 10 is merely an example; those skilled in the art can configure the specific number, function, and layout of storage compartments according to their needs. Storage compartments 121 can be divided using shelves, drawers, etc., to achieve corresponding storage functions, such as chilling, freezing, and drying storage. In some embodiments, one or more preservation storage containers 123 can be arranged within storage compartment 121. A magnetic field is applied inside the preservation storage containers 123 to enhance the preservation effect.

[0065] Figure 3 This is a schematic diagram of a preservation storage container 123 in a refrigerated and frozen storage device 10 with a magnetic field module according to an embodiment of the present invention. Figure 4 This is a schematic diagram showing the installation state of magnetic field modules 140 and 150 in a refrigerated and frozen storage device 10 with magnetic field modules according to an embodiment of the present invention. A fresh-keeping storage container 123 is arranged inside the storage compartment 121 and can be a drawer-type storage container or a storage container of other structures. Magnetic field modules 140 and 150 are disposed on the inner or outer side or side wall of the fresh-keeping storage container 123.

[0066] In some embodiments, the first magnetic field module 140 and the second magnetic field module 150 are arranged relatively apart inside the storage compartment 121, thereby forming a fresh-keeping storage space with a magnetic field between the first magnetic field module 140 and the second magnetic field module 150. The fresh-keeping storage space is used to place the stored items. The first magnetic field module 140 and the second magnetic field module 150 can be arranged vertically opposite each other or horizontally opposite each other, thereby forming a fresh-keeping storage space between the first magnetic field module 140 and the second magnetic field module 150.

[0067] Figure 5 This is an exploded view of the components of the first magnetic field module 140 in a refrigerated and frozen storage device 10 with a magnetic field module according to an embodiment of the present invention. Figure 6This is an exploded view of the components of the second magnetic field module 150 in a refrigerated and frozen storage device 10 with a magnetic field module according to an embodiment of the present invention. Each magnetic field module 140, 150 may respectively include: a housing, magnetic source components 143, 153, and magnetic conductive plates 142, 152. The housing defines an installation space, protecting the magnetic source components 143, 153 and the magnetic conductive plates 142, 152 from corrosion damage and extending their service life. The magnetic source components 143, 153 are disposed within the installation space and are used to generate a magnetic field. The magnetic source components 143, 153 may be uniformly magnetized permanent magnet sheets. For example, the permanent magnet sheets may be made of a flexible permanent magnet material, such as a flexible rubber magnetic sheet made by calendering a composite of bonded ferrite magnetic powder and synthetic rubber.

[0068] Magnetic guide plates 142 and 152 are disposed within the installation space and are attached to magnetic source components 143 and 153 to adjust the magnetic field distribution of the magnetic source components 143 and 153. Magnetic guide plates 142 and 152 are made of a material with low coercivity and high permeability, and their area can be slightly larger than that of the magnetic source components 143 and 153. The tight attachment of magnetic guide plates 142 and 152 with the magnetic source components 143 and 153 achieves a zero-gap fit, improving the uniformity of the magnetic field. Testing has shown that magnetic guide plates 142 and 152 can make the magnetic field more uniform and expand its coverage area.

[0069] The encapsulation shell is constructed to ensure that the magnetic source components 143, 153 are closer to the food preservation storage space relative to the magnetic guide plates 142, 152, and also to ensure the accurate direction of the magnetic field. That is, the internal mounting space of the encapsulation shell has different structures to limit the relative position of the magnetic source components 143, 153 and the magnetic guide plates 142, 152, ensuring that the magnetic source components 143, 153 are closer to the food preservation storage space relative to the magnetic guide plates 142, 152.

[0070] To address the characteristic that magnetic field strength gradually decreases with distance, the encapsulation shell optimizes the installation space structure to fully utilize the magnetic field released by the magnetic source components 143 and 153. The first magnetic field module 140 and the second magnetic field module 150 can have opposite magnetic poles; for example, the magnetic poles facing the magnetic field preservation space can be set as S and N poles respectively; or the magnetic poles facing the magnetic field preservation space can be set as N and S poles respectively. This further ensures the uniformity of the magnetic field. That is, the direction of the magnetic field lines is from the first magnetic field module 140 to the second magnetic field module 150; or from the second magnetic field module 150 to the first magnetic field module 140.

[0071] The first magnetic field module 140 and the second magnetic field module 150 can be configured as plates with different structures for easy differentiation. An example is provided where the first magnetic field module 140 is positioned above the second magnetic field module 150, with a vertical spacing between them. Those skilled in the art can implement other configurations based on this, such as the first magnetic field module 140 being positioned horizontally or vertically between the first and second magnetic field modules 150.

[0072] The first magnetic field module 140 includes, from the outside to the inside, the following components according to their relative positions to the preservation and storage space: a first housing 141, a magnetic plate 142, a magnetic source component 143, and a second housing 144. The second housing 144 is interlocked with the first housing 141 (or the second housing 144 is covered by the first housing 141), together defining the space for accommodating the magnetic plate 142 and the magnetic source component 143.

[0073] The second magnetic field module 150 includes, from the outside to the inside, the following components according to their relative positions to the preservation and storage space: a first housing 151, a magnetic source component 153, a magnetic guide plate 152, and a second housing 154. The second housing 154 is interlocked with the first housing 151 (or the second housing 154 is covered by the first housing 151), together defining the space for accommodating the magnetic guide plate 152 and the magnetic source component 153.

[0074] Figure 7 This is a schematic diagram of the magnetic field mounting structure 310 and a partially enlarged view of it in a refrigerated and frozen storage device 10 with a magnetic field module according to an embodiment of the present invention. Opposite magnetic field mounting structures 310 are provided on the side walls of the storage compartment 121 on both sides. Magnetic field modules 140 and 150 are respectively mounted on the magnetic field mounting structures 310 on both sides to generate a magnetic field that promotes the formation of a fresh-keeping storage environment. In some embodiments, the magnetic field mounting structure 310 is directly disposed on the side wall of the inner liner of the container or on the vertical partition of the container, 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 mounting structure 310 may also be disposed on a storage drawer slide rail device installed on the side wall of the inner liner of the container or on the vertical partition of the container; that is, the magnetic field mounting structure 310 is formed on the storage drawer slide rail device.

[0075] The magnetic field mounting structure 310 may include a slide 312 and a limiting component. The slide 312 is arranged along the front-rear direction of the housing 12, and the sides of the magnetic field modules 140 and 150 are retractably mounted within the slide 312. That is, the slide 312 has an opening facing the interior of the storage compartment 121, and the side edges of the magnetic field modules 140 and 150 are located within the slide 312. The limiting component is disposed on the bottom wall and / or side wall of the slide 312, and limits the position of the magnetic field modules 140 and 150 relative to the slide 312 by abutting against them. When needed, the user can remove the magnetic field modules 140 and 150 for cleaning.

[0076] The limiting components may include a first limiting member 311, a second limiting member 312, and a limiting rib 313, to limit the magnetic field modules 140 and 150 in multiple directions, ensuring that the magnetic field modules 140 and 150 are installed in the correct position. The first limiting member 311 is disposed on the bottom wall of the slide groove 312 and is used to abut against the side of the magnetic field modules 140 and 150. The first limiting member 311 may have a guide surface that gradually protrudes towards the magnetic field modules 140 and 150 from front to back, thereby gradually generating elastic deformation during the insertion of the magnetic field modules 140 and 150. That is to say, the guide surface of the first limiting member 311 is inclined inward from front to back, reducing the resistance during the insertion of the magnetic field modules 140 and 150, and applying limiting pressure from both sides after the magnetic field modules 140 and 150 are installed in place.

[0077] In some embodiments, each groove 312 is provided with a plurality of first limiting members 311. The plurality of first limiting members 311 are spaced apart along the front-back direction of the groove 312 to apply a more uniform limiting pressure. Figure 7 The illustration shows an embodiment with two first limiting members 311 at the front and back. Those skilled in the art can build upon this and set more first limiting members 311.

[0078] The second limiting member 312 is disposed on the upper side wall of the slide groove 312, and is used to abut against the top of the magnetic field modules 140 and 150. Limiting notches 1411 and 1511 are also provided on the top wall of the magnetic field modules 140 and 150 near the side, corresponding to the second limiting member 312, and are configured such that the magnetic field modules 140 and 150 are installed in the magnetic field mounting structure 312 to accommodate and limit the second limiting member 312. The second limiting member 312 may have a guide surface that gradually slopes downwards from front to back, thereby gradually generating elastic deformation during the insertion of the magnetic field modules 140 and 150, and finally engaging with the limiting notches 1411 and 1511.

[0079] The slide 312 is also provided with a limiting rib 313 at the rear end. The limiting rib 313 is used to abut against the rear side of the magnetic field module, thereby limiting the front and rear positions of the magnetic field modules 140 and 150.

[0080] The limiting components on both sides of the same magnetic field module 140 and 150 can be symmetrically arranged. The positions of the limiting components on both sides of the first magnetic field module 140 and the second magnetic field module 150 can be set differently to avoid incorrect insertion of the first magnetic field module 140 and the second magnetic field module 150; for example, the number and front-to-back position of the first limiting member 311 configured for the first magnetic field module 140 and the second magnetic field module 150 can be set differently, and the number and length of the limiting ribs 313 can also be set differently. Correspondingly, the positions of the limiting notch 1411 of the first magnetic field module 140 and the limiting notch 1511 of the second magnetic field module 150 are also configured accordingly, so as to cooperate with the first limiting member 311.

[0081] If the first magnetic field module 140 and the second magnetic field module 150 are inserted incorrectly or in reverse, the installation will be hindered or restricted by the limiting components, prompting the installer to adjust the installation method promptly. Specifically, the housing 12 has guide and fixing structures on both sides of the first magnetic field module 140 and the second magnetic field module 150. Furthermore, the positions and / or shapes and / or dimensions of the guide and fixing structures for the first magnetic field module 140 and the second magnetic field module 150 are different. The first magnetic field module 140 and the second magnetic field module 150 have mating structures corresponding to their respective guide and fixing structures to ensure their proper position within the storage compartment 121.

[0082] Figure 8 This is a partially enlarged schematic diagram of the first housing 141 of the first magnetic field module 140 in a refrigerated and frozen storage device 10 with a magnetic field module according to an embodiment of the present invention, and... Figure 9 This is a partially enlarged schematic diagram of the second housing 144 of the first magnetic field module 140 in a refrigerated and frozen storage device 10 with a magnetic field module according to an embodiment of the present invention. In an embodiment where the first magnetic field module 140 is arranged above the magnetic field preservation space, the first housing 141 may be the upper half of the encapsulation shell of the first magnetic field module 140, and the second housing 144 may be the lower half of the encapsulation shell of the first magnetic field module 140. The first housing 141 and the second housing 144 are respectively provided with a plurality of mutually cooperating peripheral connecting portions 163, 164 near their peripheral walls, and the middle portions of the first housing and the second housing are respectively provided with mutually cooperating central limiting structures 161, 162.

[0083] In embodiments where the first magnetic field module 140 is configured as a square plate, the peripheral connecting portions 163, 164 include snap-fit ​​connection structures and / or screw connection structures. Figure 8 and Figure 9 The diagram shows a snap-fit ​​connection structure embodiment where a bayonet 164 is provided near the edge of the first housing 141, and a latch 163 that mates with the bayonet 164 is provided near the edge of the second housing 144. That is, the peripheral connecting portion includes the bayonet 164 and the latch 163 that mates with it. Those skilled in the art can design various types of snap-fit ​​connection structures according to specific fixed connection requirements. The peripheral connecting portions 163 and 164 can ensure a reliable peripheral connection and fixation of the first magnetic field module 140, and can reliably press the magnetic source component 143 and the magnetic guide plate 142 together.

[0084] The first magnetic field module 140 is set up in a low-temperature operating environment of refrigeration and freezing for a long time. The peripheral connecting parts 163 and 164 alone cannot guarantee that the encapsulation shell can press the magnetic source 143 and the magnetic plate 142 together. This may cause local voids, thereby avoiding the increase of magnetic resistance in local areas and the resulting uneven magnetic field.

[0085] In the field of magnetic fields, those skilled in the art generally believe that ensuring a uniform magnetic field distribution requires ensuring the integrity of the magnetic source component's surface. However, in the magnetic field module 140 of this embodiment, the inventors creatively realized that when the magnetic source component 143 and the magnetic conductive plate 142 are arranged simultaneously, the flatness of their fit has a greater impact on the uniformity of the magnetic field. To address this issue, the inventors also attempted to use adhesives to bond the magnetic source component 143 and the magnetic conductive plate 142. However, the thickness of the adhesive is difficult to control, and it will age over long-term use, making it difficult to achieve a flat fit between the magnetic source component 143 and the magnetic conductive plate 142.

[0086] Based on the above problems, this embodiment provides a central limiting structure that mutually cooperates with each other in the middle of the first housing 141 and the middle of the second housing 144. The central limiting structure may include a first limiting part 161 and a second limiting part 162. The first limiting part 161 is disposed on the inner surface of the first housing 141 and extends toward the second housing 144. The second limiting part 162 is disposed on the inner surface of the second housing 144 at a position opposite to the first limiting part 161, and the first limiting part 161 and the second limiting part 162 can be connected by a snap-fit ​​structure to limit the distance between the inner surface of the first housing 141 and the inner surface of the second housing 144. That is, the inner middle parts of the first housing 141 and the inner middle parts of the second housing 144 extend relative to each other, cooperate with each other, and are connected at their ends by a snap-fit ​​structure. The magnetic source component 143 and the magnetic guide plate 142 are provided with through holes at positions corresponding to the respective central limiting structures, allowing the central limiting structures to pass through. The central limiting structure can press the central area of ​​the magnetic source component 143 and the magnetic guide plate 142 together, and with the peripheral connecting parts 163, 164, the magnetic source component 143 and the magnetic guide plate 142 can be tightly fitted together.

[0087] In other embodiments, the central limiting structure may also use other methods, such as including a screw post and a connecting screw. The screw post is disposed 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 opposite side to define the distance between the inner surface of the first housing 141 and the inner surface of the second housing 144.

[0088] The enclosure of the second magnetic field module 150 can have a similar structure. In an embodiment where the second magnetic field module 150 is spaced below the first magnetic field module 140, the first housing 151 can be the upper half of the enclosure of the second magnetic field module 150, and the second housing 154 can be the lower half of the enclosure of the second magnetic field module 140.

[0089] The first housing 151 and the second housing 154 are each provided with a plurality of mutually cooperating peripheral connecting parts near their peripheral walls, and each also has a mutually cooperating central limiting structure. The peripheral connecting parts can use snap-fit ​​connection structures and / or screw connection structures. The central limiting structures of the first housing 151 and the second housing 154 also have mutually cooperating central limiting structures, which can use mutually extending and cooperating snap-fit ​​structures. The magnetic source component 153 and the magnetic guide plate 152 are reliably pressed together as a whole to achieve a tight fit.

[0090] The position of the central limiting structure of the first magnetic field module 140 relative to the geometric center of the first magnetic field module 140 is different from the position of the central limiting structure of the second magnetic field module 150 relative to the geometric center of the second magnetic field module 150. For example, the offset method of the central limiting structure of the first magnetic field module 140 in the front-back direction or the left-right lateral direction is different from the offset method of the central limiting structure of the second magnetic field module 150. Accordingly, the magnetic source component 143 and the magnetic guide plate 142 of the first magnetic field module 140 and the magnetic source component 153 and the magnetic guide plate 152 of the second magnetic field module 150 are respectively set differently, which can ensure that the above components will not be mis-assembled.

[0091] The sizes of the first magnetic field module 140 and the second magnetic field module 150 can also be set to be the same or different depending on the space constraints of the housing 12 they are in, and their relative arrangement can be roughly opposite. For example, in some embodiments, the first magnetic field module 140 may be set to be slightly smaller than the second magnetic field module 150 due to the limitation of the cooling air duct or other components.

[0092] Figure 10 This is a schematic diagram showing the state of the first housing 141 of the first magnetic field module 140 in a refrigerated and frozen storage device 10 with a magnetic field module after the magnetic source component 143 and the magnetic guide plate 142 are installed, and a partial enlargement thereof, according to an embodiment of the present invention.

[0093] Support ribs 181 are provided on the inner surface of the first housing 141 of the first magnetic field module 140, in the area opposite to the magnetic conductive plate 142. Support ribs 181 are also provided on the inner surface of the second housing 144, in the area opposite to the magnetic source component 143. The support ribs 181 abut against the magnetic conductive plate 142 and the magnetic source component 143, so that the magnetic conductive plate 142 and the magnetic source component 143 are tightly fitted together.

[0094] The support ribs 181 can be configured as annular rings surrounding the central limiting structures 161, 162. The minimum distance between adjacent support ribs 181 is set to be less than the sum of the thicknesses of the magnetic plate 142 and the magnetic source component 143. This limits the density of the support ribs 181 to prevent voids from appearing at the spacing between them. The width of the top surface of the support rib 181 (serving as the contact surface against the magnetic plate 142 or the magnetic source component 143) is set to be greater than the sum of the thicknesses of the magnetic plate 142 and the magnetic source component 143. The support ribs 181 also improve the structural strength of the encapsulation shell, and in conjunction with the peripheral connecting parts 163, 164 and the central limiting structures 161, 162, achieve long-term structural stability. The minimum distance between the aforementioned support ribs 181 and the width of the top surface of the support ribs 181 are improvements made by the inventors after in-depth research on the structure and material characteristics of the magnetic plate 142 and the magnetic source component 143. After physical verification of the samples, the results exceeded expectations and far surpassed the fit effect when the plane abuts against the magnetic plate 142 or the magnetic source component 143.

[0095] The structure of the supporting ribs 181 and their relative positions are set according to the situation of the magnetic plate 142 and the magnetic source component 143. On the one hand, this improves the structural strength and stability, and on the other hand, it ensures that the magnetic plate 142 and the magnetic source component 143 are reliably attached.

[0096] The first housing 141 includes a first outer housing panel 1412 and a first outer housing peripheral wall 1413 disposed at the edge of the first outer housing panel 1412. The inner surface of the first outer housing panel 1412 is provided with a first positioning structure 172 for fixing the magnetic conductive plate 142 and a second positioning structure 171 for fixing the magnetic source component 143. The first positioning structure 172 and the second positioning structure 171 together maintain the relative position of the magnetic conductive plate 142 and the magnetic source component 143.

[0097] The first positioning structure 172 includes positioning ribs protruding from the wall surface. The shape formed by the positioning ribs and / or their extensions is adapted to the outer peripheral contour of the magnetic guide plate 142, thereby confining the magnetic guide plate 142 within the area enclosed by the positioning ribs and / or the extensions of the first positioning ribs. That is, after the magnetic guide plate 142 is installed, it is snapped into the area defined by the positioning ribs. When the size of the magnetic guide plate 142 is larger than that of the magnetic source member 143, the magnetic guide plate 142 has an extended region on the outer periphery of the area abutting against the magnetic source member 143.

[0098] The second positioning structure 171 includes a protrusion extending from the positioning rib towards the central region of the wall. The outer region of the magnetic plate 142 has a positioning notch at a corresponding position on the protrusion, and the protruding length matches the width of the outer region, thereby causing the end of the protrusion to abut against the magnetic source component 143, thus positioning the magnetic source component 143. The magnetic source component 143 and the magnetic plate 142 are both generally square, and multiple sides of the positioning rib are provided with one or more protrusions. That is, the second positioning structure 171 is arranged at the notch position of the magnetic plate 142, and after the magnetic source component 143 is installed, it is engaged in the area defined by the second positioning structure 171.

[0099] The first positioning structure 172 and the second positioning structure 171 described above can ensure that the magnetic plate 142 and the magnetic source component 143 are installed in the correct manner, and will not be installed backwards or incorrectly.

[0100] The installation process of the first magnetic field module 140 is as follows: the inner side of the first housing 141 is arranged upwards; the magnetic plate 142 is embedded in the first positioning structure 172 on the inner surface of the first outer shell panel 1412 of the first housing 141; then the magnetic source component 143 is arranged on the magnetic plate 142 and cooperates with the second positioning structure 171 on the inner surface of the first outer shell panel 1412; the second housing 144 is fastened to the first housing 141, so that the peripheral connecting parts 163, 164 and the central limiting structures 161, 162 are reliably connected. Finally, the entire assembly is flipped over to obtain the first magnetic field module 140.

[0101] Figure 11 This is a schematic diagram of the first housing 151 of the second magnetic field module 150 in a refrigerated and frozen storage device 10 with a magnetic field module according to an embodiment of the present invention, and a partially enlarged view thereof. Figure 12 This is a schematic diagram showing the state of the first housing 151 of the second magnetic field module 150 in a refrigerated and frozen storage device 10 with a magnetic field module after the magnetic source component 153 is installed, and a partial enlargement thereof, according to an embodiment of the present invention. Figure 13 This is a schematic diagram showing the state of the first housing 151 of the second magnetic field module 150 in a refrigerated and frozen storage device 10 with a magnetic field module after the magnetic source component 153 and the magnetic guide plate are installed, and a partial enlargement thereof, according to an embodiment of the present invention.

[0102] Since the second housing 154 of the second magnetic field module 150 is similar in structure to the first housing 141 of the first magnetic field module 140, and the support ribs 181 on the plates of the first housing 151 and the second housing 154 that abut against the magnetic source component 153 and the magnetic guide plate 152 are similar in structure to the support ribs 181 of the first magnetic field module 140, no further details will be provided.

[0103] The first housing 151 of the second magnetic field module 150 is configured with positioning components to limit the magnetic source component 153 and the magnetic guide plate 152 respectively. The first housing 151 includes a first outer shell panel 1512 and a first outer shell peripheral wall 1513 disposed on the edge of the first outer shell panel 1512.

[0104] The first outer casing panel 1512 abuts against the side of the magnetic source component 153 opposite to the magnetic guide plate 152. The first outer casing panel 1512 is provided with a first positioning rib 173. The shape formed by the extension lines of the first positioning rib 173 is adapted to the outer peripheral contour of the magnetic source component 153, thereby confining the magnetic source component 153 within the area enclosed by the extension lines of the first positioning rib 173. The height of the first positioning rib 173 is configured such that, when the magnetic source component 153 is mounted on the first outer casing panel, the top of the first positioning rib 173 is flush with or lower than the magnetic source component 153. The magnetic guide plate 152 is larger than the magnetic source component 153, and the above structure can avoid structural interference with the magnetic guide plate 152.

[0105] The first outer casing panel 1512 is further provided with a second positioning rib 174 on the outside of the first positioning rib 173. The height of the second positioning rib 174 is configured such that when the magnetic source member 153 is mounted on the first outer casing panel 1512, the top of the second positioning rib 174 is higher than the magnetic source member 153, and the shape formed by the extension line of the second positioning rib 174 is adapted to the outer peripheral contour of the magnetic guide plate 152, thereby confining the magnetic guide plate 152 within the area enclosed by the extension line of the second positioning rib 174.

[0106] The magnetic source component 153 and the magnetic guide plate 152 are generally square with one corner missing. The shape formed by the extension lines of the first positioning rib 173 and the shape formed by the extension lines of the second positioning rib 174 are also set to have one corner missing, so as to avoid incorrect installation direction.

[0107] The installation process of the second magnetic field module 150 is as follows: The inner side of the first housing 151 is arranged upwards; the magnetic source component 153 is embedded into the first positioning rib 173 on the inner surface of the first outer shell panel 1512 of the first housing 151; then, the magnetic guide plate 152 is arranged on the magnetic source component 153, cooperating with the second positioning rib 174 on the inner surface of the first outer shell panel 1512. The second housing 144 is then fastened onto the first housing 141, ensuring a reliable connection between the peripheral connecting portion and the central limiting structure. Finally, the entire assembly is flipped over to obtain the second magnetic field module 150.

[0108] The second magnetic field module 150 uses two positioning ribs of different heights to position and install two components of different sizes, namely the magnetic source component 153 and the magnetic guide plate 152.

[0109] Figure 14 This is a schematic diagram of the magnetic field module in a refrigerated and frozen storage device 10 with a magnetic field module according to another embodiment of the present invention; Figure 15 yes Figure 14 The exploded view of the magnetic field module components is shown. This embodiment of the magnetic field module provides another fixed connection structure for the first magnetic field module 140. Multiple screw posts extend from the inner side of the first housing 141, serving as a central limiting structure and a peripheral connecting part, respectively. Multiple screw holes are provided on the second housing 144, and screws 145 connect and fix the first housing 141 and the second housing 144 through the screw holes and screw posts, thereby achieving height limiting.
