Description

[0002] The fresh-keeping and storage effect of household refrigerating and freezing equipment such as refrigerators has become an important indicator for measuring the performance of such equipment. Fresh meat, fish and shrimp ingredients are prone to problems such as juice loss, resulting in a poor taste and a dark color during storage.

[0003] Now it is found through research that the magnetic field also has a certain impact on the fresh-keeping and storage of ingredients. 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 makes the phenomenon of water molecules clustering into large molecular clusters occur. It changes the cluster phenomenon of water and forms 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. This not only promotes the rapid passage of the freezing process through the phase change stage, but also reduces the damage of ice crystals to the cells of the ingredients. Therefore, introducing a suitable magnetic field into the refrigerating and freezing storage device can help improve the fresh-keeping and storage effect of the ingredients.

[0050] This embodiment provides a refrigerating and freezing storage device with a magnetic field module. 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.

[0052] 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 may be defined inside the box body 12, usually a plurality of them, 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 1 The refrigerating and freezing storage device 10 of the shown cross-over double-door refrigerator 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 storage compartment 121 can be spatially divided by means such as a shelf, a partition board, a drawer, etc. to achieve corresponding storage functions, such as chilled storage, freezing storage, dry storage, and so on. In some embodiments, one or more fresh-keeping storage containers 123 may 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.

[0053] Figure 3 is a schematic diagram of a fresh-keeping storage container 123 in a refrigerating and freezing storage device 10 with a magnetic field module according to an embodiment of the present utility model.Figure 4 It is a schematic diagram of the installation states of the magnetic field modules 140 and 150 in the refrigerating and freezing storage device 10 with a magnetic field module according to an embodiment of the present invention. The fresh-keeping storage container 123 is arranged in the storage compartment 121 and can be a drawer-type storage container or a storage container with other structures. The magnetic field modules 140 and 150 are provided on the inner side, outer side or side wall of the fresh-keeping storage container 123.

[0054] For example, both sides of the magnetic field modules 140 and 150 are respectively installed on the magnetic field installation parts for generating a magnetic field that promotes the formation of a fresh-keeping storage environment. The magnetic field modules 140 and 150 can be one or multiple. When the magnetic field modules 140 and 150 are multiple, they can be arranged at intervals in the height direction. In some embodiments, the magnetic field modules 140 and 150 can be used as a shelf board and directly used for placing food ingredients or other stored items. The magnetic field modules 140 and 150 can be in a plate shape.

[0055] In the embodiment where the first magnetic field module 140 and the second magnetic field module 150 are respectively provided at the upper and lower parts of the fresh-keeping storage container 123, the first magnetic field module 140 and the second magnetic field module 150 are relatively spaced apart inside the storage compartment 121, so as to form a fresh-keeping storage space with a magnetic field for placing stored items between the first magnetic field module 140 and the second magnetic field module 150. The first magnetic field module 140 and the second magnetic field module 150 can be arranged vertically opposite or horizontally opposite, so as to form a fresh-keeping storage space between the first magnetic field module 140 and the second magnetic field module 150.

[0056] Figure 5 It is a schematic diagram of the magnetic field installation part 310 and its partial enlargement in the refrigerating and freezing storage device 10 with a magnetic field module according to an embodiment of the present invention. Opposite magnetic field installation parts 310 are provided on the two vertical side walls (i.e., the left and right side walls shown in the figure) of the storage compartment 121. Both sides of the magnetic field modules 140 and 150 are respectively installed on the magnetic field installation parts 310 for generating a magnetic field that promotes the formation of a fresh-keeping storage environment.

[0057] In some embodiments, the magnetic field installation part 310 is directly provided on the side wall of the inner box body or the vertical partition board of the box body, that is, directly formed on the side wall of the storage compartment 121.

[0058] In other embodiments, when the fresh-keeping storage container 123 is a drawer-type storage container, the magnetic field installation part 310 can also be provided on the storage drawer slide rail device installed on the side wall of the inner box body or the vertical partition board of the box body; that is to say, the magnetic field installation part 310 is formed on the storage drawer slide rail device.

[0059] The magnetic field installation part 310 may include: a sliding groove 312 and a limiting component. The sliding groove 312 may be arranged along the front-back direction of the box body 12, and the sides of the magnetic field modules 140, 150 are slidably arranged in the sliding groove 312. That is, the sliding groove 312 has an opening facing the inside of the storage compartment 121, and the two side edges of the magnetic field modules 140, 150 are arranged in the sliding groove 312. The limiting component is arranged on the bottom wall and / or side wall of the sliding groove 312, and limits the positions of the magnetic field modules 140, 150 relative to the sliding groove 312 by abutting against the magnetic field modules 140, 150. When needed, the user can remove the magnetic field modules 140, 150 for cleaning.

[0060] The limiting component may include: a first limiting member 311, a second limiting member 312, and a limiting rib 313, which realize the limiting of the magnetic field modules 140, 150 in multiple directions and ensure the installation of the magnetic field modules 140, 150 in the correct positions.

[0061] The first limiting member 311 is arranged on the bottom wall of the sliding groove 312 and is used to abut against the side walls of the magnetic field modules 140, 150. The first limiting member 311 may have a guiding surface that gradually protrudes towards the magnetic field modules 140, 150 from front to back, so as to gradually generate elastic deformation during the insertion of the magnetic field modules 140, 150. That is to say, the guiding surface of the first limiting member 311 is inclined inwards from front to back, reducing the resistance during the insertion of the magnetic field modules 140, 150, and applying a limiting pressure from both sides after the magnetic field modules 140, 150 are installed in place.

[0062] In some embodiments, a plurality of first limiting members 311 are arranged in each sliding groove 312. The plurality of first limiting members 311 are arranged at intervals along the front-back direction of the sliding groove 312, applying a more uniform limiting pressure. Figure 5 An embodiment with two first limiting members 311 at the front and back is shown. Those skilled in the art can, on this basis, set a greater number of first limiting members 311.

[0063] The second limiting member 312 is arranged on the inner upper wall surface of the sliding groove 312, that is, it can be located at the top of the side walls of the magnetic field modules 140, 150, and is used to abut against the magnetic field modules 140, 150 from the top of the magnetic field modules 140, 150. A limiting notch is also arranged at the position corresponding to the second limiting member 312 on the top wall of the magnetic field modules 140, 150, and is configured to accommodate the second limiting member to achieve limiting after the magnetic field modules are installed in the magnetic field installation part.

[0064] A limiting rib 313 is further arranged at the rear end of the sliding groove 312, and the limiting rib 313 is used to abut against the rear sides of the magnetic field modules, so as to limit the front-back positions of the magnetic field modules 140, 150.

[0065] Figure 5Exploded view of components of the first magnetic field module 140 in the refrigerating and freezing storage device 10 with a magnetic field module according to an embodiment of the present utility model; Figure 6 Exploded view of components of the second magnetic field module 150 in the refrigerating and freezing storage device 10 with a magnetic field module according to an embodiment of the present utility model. Each magnetic field module 140, 150 may respectively include: a protection component, magnetic source members 143, 153, and magnetic conduction plates 142, 152. The protection component is located outside the magnetic source members 143, 153 and the magnetic conduction plates 142, 152 for preventing the magnetic source members 143, 153 and the magnetic conduction plates 142, 152 from being contaminated or corroded.

[0066] In some embodiments, the protection component may include a packaging shell which defines an installation space for arranging the magnetic source members 143, 153 and the magnetic conduction plates 142, 152 to protect the magnetic source members 143, 153 and the magnetic conduction plates 142, 152 from corrosion damage and extend their service life. The magnetic source members 143, 153 are arranged in the installation space and are used for generating a magnetic field. The magnetic source members 143, 153 may be permanent magnet sheets with uniform magnetization. For example, the permanent magnet sheets 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.

[0067] The magnetic conduction plates 142, 152 are arranged in the installation space and are arranged in contact with the magnetic source members 143, 153 for adjusting the magnetic field distribution of the magnetic source members 143, 153. The magnetic conduction plates 142, 152 are made of a material with low coercivity and high magnetic permeability, and their area may be slightly larger than that of the magnetic source members 143, 153. The close fit of the magnetic conduction plates 142, 152 and the magnetic source members 143, 153 can achieve a zero-gap fit, improving the uniformity of the magnetic field. Through testing, the magnetic conduction plates 142, 152 can make the magnetic field more uniform and expand the coverage range of the magnetic field.

[0068] The packaging shell is constructed such that the installation space ensures that the magnetic source members 143, 153 are closer to the fresh-keeping storage space relative to the magnetic conduction plates 142, 152 and also ensures the accurate direction of the magnetic field. In view of the characteristic that the magnetic field intensity gradually decays with distance, the packaging shell makes full use of the magnetic field released by the magnetic source members 143, 153 by optimizing the structure of the installation space. The opposite magnetic poles of the first magnetic field module 140 and the second magnetic field module 150 may be opposite-sex magnetic poles. For example, the magnetic poles facing the magnetic field fresh-keeping space are respectively set as the S pole and the N pole; or the magnetic poles facing the magnetic field fresh-keeping space are respectively set as the N pole and the S pole. This can also further ensure the uniformity of the magnetic field. That is, the direction of the magnetic force 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.

[0069] The first magnetic field module 140 and the second magnetic field module 150 are each integrally provided in a plate shape, and their structures are set differently for distinction. Taking the first magnetic field module 140 and the second magnetic field module 150 which are arranged at a relative interval above and below each other as an example, with the first magnetic field module 140 located above the second magnetic field module 150. Those skilled in the art can implement other configurations such as the first magnetic field module 140 being spaced left and right of the second magnetic field module 150 on this basis.

[0070] The first magnetic field module 140, in order from outside to inside relative to the fresh-keeping storage space, includes: a first outer shell portion 141, a magnetic conduction plate 142, a magnetic source member 143, and a second outer shell portion 144. The second outer shell portion 144 is buckled with the first outer shell portion 141 (it can also be said that the second outer shell portion 144 covers the first outer shell portion 141), jointly defining a space for accommodating the magnetic conduction plate 142 and the magnetic source member 143.

[0071] The second magnetic field module 150, in order from outside to inside relative to the fresh-keeping storage space, includes: a first outer shell portion 151, a magnetic source member 153, a magnetic conduction plate 152, and a second outer shell portion 154. The second outer shell portion 154 is buckled with the first outer shell portion 151 (it can also be said that the second outer shell portion 154 covers the first outer shell portion 151), jointly defining a space for accommodating the magnetic conduction plate 152 and the magnetic source member 153.

[0072] In the embodiment where the first magnetic field module 140 is arranged above the magnetic field fresh-keeping space, the first outer shell portion 141 can be the upper half of the encapsulation shell of the first magnetic field module 140, and the second outer shell portion 144 can be the lower half of the encapsulation shell of the first magnetic field module 140. At positions adjacent to the peripheral walls of the first outer shell portion 141 and the second outer shell portion 144, a plurality of mutually cooperating peripheral side connection structures are respectively provided, and at the middle parts of the first outer shell portion 141 and the second outer shell portion 144, there are also mutually cooperating middle part limiting structures. The peripheral side connection structures and the middle part limiting structures can use snap structures or screw fastening structures.

[0073] The encapsulation shell of the second magnetic field module 150 can have a similar structure. In the embodiment where the second magnetic field module 150 is arranged at an interval below the first magnetic field module 140, its first outer shell portion 151 can be the upper half of the encapsulation shell of the second magnetic field module 150, and the second outer shell portion 154 can be the lower half of the encapsulation shell of the second magnetic field module 140.

[0074] The positions of the central limiting structures of the first magnetic field module 140 relative to the geometric center of the first magnetic field module 140 and the positions of the central limiting structures of the second magnetic field module 150 relative to the geometric center of the second magnetic field module are set to be different. For example, the offset modes of the central limiting structures of the first magnetic field module 140 in the front-rear direction or the left-right transverse direction are set to be different from those of the central limiting structures of the second magnetic field module 150. Correspondingly, the magnetic source members 143 and magnetic conduction plates 142 of the first magnetic field module 140 and the magnetic source members 153 and magnetic conduction plates 152 of the second magnetic field module 150 are respectively set to be different, so as to ensure that the above components will not be misassembled.

[0075] 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 according to the space limitations of the box body 12 where they are located, and their relative settings can be generally opposite. For example, in some embodiments, the first magnetic field module 140 is restricted by the refrigeration air duct or other components and can be set to be slightly smaller than the second magnetic field module 150; or the second magnetic field module 150 is restricted by the refrigeration air duct or other components and can be set to be slightly smaller than the first magnetic field module 140.

[0076] The encapsulation housing is configured such that the installation space ensures that the magnetic source members 143, 153 are closer to the fresh-keeping storage space relative to the magnetic conduction plates 142, 152, and also ensures the accurate magnetic field direction. In view of the characteristic that the magnetic field intensity gradually decays with distance, the encapsulation housing optimizes the installation space structure to make full use of the magnetic fields released by the magnetic source members 143, 153. The opposite magnetic poles of the first magnetic field module 140 and the second magnetic field module 150 can be opposite-sex magnetic poles. For example, the magnetic poles facing the magnetic field fresh-keeping space side are respectively set as the S pole and the N pole; or the magnetic poles facing the magnetic field fresh-keeping space side are respectively set as the N pole and the S pole. This can also further ensure the uniformity of the magnetic field. That is, the direction of the magnetic force 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.

[0077] Limiting notches 1411, 1511 are also provided at the positions of the top walls of the magnetic field modules 140, 150 corresponding to the second limiting member 312, and are configured to accommodate the second limiting member 312 to achieve limiting after the magnetic field modules 140, 150 are installed on the magnetic field installation portion 312. The second limiting member 312 can have a guiding surface that gradually protrudes downward and obliquely from front to back, so that elastic deformation gradually occurs during the insertion process of the magnetic field modules 140, 150, and finally engages with the limiting notches 1411, 1511.

[0078] The limiting components on both sides of the same magnetic field modules 140 and 150 can be symmetrically arranged. The positions of the limiting components in contact with the first magnetic field module 140 and at least part of the limiting components in contact with the second magnetic field module 150 are different, so as to prevent the first magnetic field module 140 and the second magnetic field module 150 from being inserted wrongly; for example, the number and the front and rear positions of the first limiting members 311 respectively configured for the first magnetic field module 140 and the second magnetic field module 150 can be set to be different, and the number of the limiting ribs 313 and the length of the rib strips can also be set to be different. Correspondingly, the positions of the limiting notches 1411 of the first magnetic field module 140 and the limiting notches 1511 of the second magnetic field module 150 are also correspondingly configured to cooperate with the first limiting members 311.

[0079] If the first magnetic field module 140 and the second magnetic field module 150 are inserted wrongly or inserted reversely by themselves, then resistance or limitation will be imposed by the limiting components to remind the installer and prompt timely adjustment of the installation method. That is, guiding and fixing structures are respectively arranged on the lateral sides (left and right sides) of the box body 12 at the first magnetic field module 140 and the second magnetic field module 150. And the positions and / or shapes and / or sizes of the guiding and fixing structures of the first magnetic field module 140 and the second magnetic field module 150 are set to be different. Corresponding positions of the first magnetic field module 140 and the second magnetic field module 150 corresponding to the respective guiding and fixing structures are provided with mating structures for mating therewith to ensure the positions of the first magnetic field module 140 and the second magnetic field module 150 in the storage compartment 121.

[0080] In some other embodiments, the protection component may further include a plastic film. The plastic film is attached to the outer surfaces of the magnetic source member and the magnetic conduction plate. That is, a soft material is used to encapsulate the shell, such as a plastic film. The raw materials of the plastic film usually include materials such as PET, PE, and EVA. The plastic film has the functions of moisture-proof, waterproof, anti-fading, anti-forgery, and is convenient for long-term preservation, thereby protecting the magnetic source member and the magnetic conduction plate. The thickness of the plastic film can be preferably 0.5 mm, and the specific thickness can be selected according to needs. When the magnetic conduction plate is larger than the magnetic source member, the area where the magnetic conduction plate is attached to the magnetic source member can be set as a concave portion, and the magnetic source member is arranged in the concave portion, so that the magnetic field component is generally flat, which is convenient for plastic sealing.

[0081] For the refrigerating and freezing storage device 10 with a magnetic field module of the present utility model, the magnetic field modules 140 and 150 are installed on the magnetic field installation part and used to generate a magnetic field for promoting the formation of a fresh-keeping storage environment. The side parts of the magnetic field module are slidably arranged in the sliding grooves of the magnetic field installation part; the limiting components are arranged on the bottom wall and / or the side wall of the sliding groove and limit the position of the magnetic field module relative to the sliding groove by being in contact with the magnetic field module. The magnetic field module can be pulled out conveniently, which is convenient for detachable setting, improves the production efficiency during the production process, and ensures that the magnetic field module can be assembled accurately and quickly; during the use process, it is convenient for the user to clean and improves the user experience.

[0082] Further, the magnetic field modules 140 and 150 use the encapsulation housing to enclose and protect the internal magnetic source components 143 and 153, as well as the magnetic conductive plates 142 and 152, to prevent the magnetic source components 143 and 153 and the magnetic conductive plates 142 and 152 from being contaminated or corroded when exposed in the fresh-keeping storage space, thereby prolonging the service life of the magnetic field components and improving the reliability of the magnetic field components.

[0083] Further, for the refrigerating and freezing storage device 10 with a magnetic field module of the present utility model, the position and structure of the magnetic field limiting assembly are optimized, and the magnetic field module is limited from multiple directions, ensuring that the magnetic field module is reliably limited.
