[0046] Currently, more and more household food preservation devices utilize magnetic fields for preservation. However, for a magnetic field to work effectively, it needs to reach a certain strength and be uniform in shape. Existing preservation devices suffer from poor preservation performance.

[0047] This application provides a preservation chamber structure and preservation equipment to solve the problem of poor preservation effect in existing preservation equipment. The following will be described in conjunction with the accompanying drawings. Figure 1-10 Please provide an explanation.

[0048] The preservation compartment structure provided in this application embodiment can be applied to preservation equipment, such as refrigerators, freezers, and preservation cabinets. For an example, please refer to [link to example]. Figure 9 , Figure 9 This is a schematic diagram of the structure of the preservation compartment provided in an embodiment of this application. (Reference) Figure 1 and Figure 2 As shown, the fresh-keeping compartment structure may include a fresh-keeping compartment 100, a first magnetic field assembly 200, and a second magnetic field assembly 300, which are respectively disposed on opposite sides of the fresh-keeping compartment 100; wherein, the first magnetic field assembly 200 includes a first magnet 210 and a first coil 220, with the first coil 220 arranged around the outside of the first magnet 210; and / or, the second magnetic field assembly 300 includes a second magnet 310 and a second coil, with the second coil arranged around the outside of the second magnet 310.

[0049] In this embodiment, the fresh-keeping compartment 100 has a storage space for storing food that needs to be kept fresh. The first magnetic field component 200 and the second magnetic field component 300 are located on both sides of the fresh-keeping compartment 100, for example, arranged on the upper and lower sides, left and right sides, or front and back sides of the fresh-keeping compartment 100. The magnetic fields generated complement each other in the space, thereby ensuring the uniform distribution of the magnetic field in the entire fresh-keeping compartment 100, reducing magnetic field dead zones, and allowing the food to be effectively affected by the magnetic field at any position in the fresh-keeping compartment 100.

[0050] Furthermore, a first coil 220 is arranged around the first magnet 210, or a second coil is arranged around the second magnet 310, so that the magnetic field generated when the coil is energized is superimposed with the magnetic field of the magnet itself, thereby enhancing the overall magnetic field strength and improving the preservation effect on food.

[0051] Furthermore, the magnetic field preservation method using coils and magnets allows for adjustment of the coil current to regulate the overall magnetic field strength, adapting to the preservation needs of different types of food.

[0052] In one optional embodiment, the magnetic field generated by the first coil 220 is in the same direction as the magnetic field of the first magnet 210; or, the magnetic field generated by the second coil is in the same direction as the magnetic field of the second magnet 310.

[0053] For example, refer to Figure 2 and Figure 4 As shown, when the first coil 220 is energized, the direction of the magnetic field it generates is the same as the direction of the magnetic field of the first magnet 210. This superposition of magnetic fields in the same direction can more effectively enhance the magnetic field strength and improve the preservation effect, which is especially suitable for food that requires a strong magnetic field for preservation. The direction of the magnetic field of the second coil is similar.

[0054] In one alternative implementation, refer to Figure 1 and Figure 3 As shown, the first magnetic field assembly 200 includes a mounting plate 230 and a first cover plate 240. The mounting plate 230 is used to fix to the preservation equipment. The first cover plate 240 is mounted on the mounting plate 230. The first cover plate 240 has a mounting groove 241 on the side facing the mounting plate 230. The first magnet 210 is mounted in the mounting groove 241.

[0055] In one alternative embodiment, the first magnetic field component 200 can be fixed to the fresh-keeping compartment 100; in another alternative embodiment, the first magnetic field component 200 can be fixed to the fresh-keeping device by means of a mounting plate 230, and the first magnetic field component 200 will not be affected when the fresh-keeping compartment 100 (e.g., a fresh-keeping drawer) is pulled out.

[0056] During assembly, the mounting plate 230 can be fixed to the preservation equipment first, then the first magnet 210 can be installed in the mounting groove 241 of the first cover plate 240, and then the cover plate can be installed on the mounting plate 230 as a whole, so that the first magnet 210 is installed between the mounting plate 230 and the first cover plate 240, sealing the first magnet 210 and ensuring that the first magnet 210 is firmly fixed during use to prevent it from falling off.

[0057] Optionally, the first cover plate 240 is snapped onto the mounting plate 230 via a snap-fit ​​structure, facilitating installation and removal.

[0058] In one alternative implementation, refer to Figure 2 As shown, the first cover plate 240 is provided with a surrounding plate 242, which surrounds and forms an installation groove 241. The surrounding plate 242 is provided with a snap-fit ​​member 243. When the first magnet 210 is installed in the installation groove 241, the snap-fit ​​member 243 snaps into the first magnet 210.

[0059] In this embodiment, a surrounding plate 242 is provided on the first cover plate 240. The surrounding plate 242 surrounds and forms a closed mounting groove 241. The function of the surrounding plate 242 is to define the mounting position of the first magnet 210 and provide a stable support and limiting structure. The first magnet 210 can be fixed in the mounting groove 241 by snap-fit, which facilitates the installation and replacement of the magnet, while keeping the first magnet 210 stable and not easy to fall off, thus improving the stability of the magnetic field and the preservation effect. Moreover, the surrounding plate 242 can be integrally formed with the first cover plate 240, which enhances the structural strength of the first cover plate 240 and improves the durability of the preservation compartment structure.

[0060] For example, there can be multiple snap-fit ​​pieces 243. The multiple snap-fit ​​pieces 243 can be distributed along the four corners of the mounting groove 241, or arranged sequentially at intervals along the circumference of the mounting groove 241. The installation stability of the first magnet 210 is improved by multi-point snap-fit ​​fixing.

[0061] For example, the snap-fit ​​243 may be a snap or hook with a certain elasticity, which can provide a certain pressure to press the first magnet 210 into the mounting groove 241 for secure fixation.

[0062] In some alternative embodiments, the first magnet 210 can also be fixed in the mounting groove 241 by means of an adhesive, which can be epoxy resin, silicone, double-sided tape or other suitable adhesive material to provide strong adhesion.

[0063] In some alternative embodiments, a surrounding plate 242 may be provided on the mounting plate 230 to form a mounting groove 241, the first magnet 210 may be installed in the mounting groove 241 of the mounting plate 230, and then the first cover plate 240 may be installed for sealing.

[0064] In one alternative implementation, refer to Figure 2 As shown, there are multiple enclosure panels 242, which are spaced apart, and each enclosure panel 242 is equipped with a first magnet 210.

[0065] It is understandable that a certain magnetic field strength and uniformity are required in the freshness-preserving compartment 100 to achieve a satisfactory preservation effect. In existing technologies, to generate a large magnetic field strength, large-area magnets or soft magnetic sheets are often used to arrange around the space of the freshness drawer. This is not only bulky but also takes up preservation space and is costly.

[0066] In this embodiment, by arranging multiple first magnets 210 at intervals, not only can the use of magnetic materials be reduced, thereby reducing weight, space occupation, and manufacturing costs, but the magnetic field strength and uniformity of the food preservation drawer can also be improved, achieving the goal of using the least amount of magnetic materials to achieve a good preservation effect.

[0067] Optionally, the shape of the first magnet 210 may include, but is not limited to, a rectangle, a square, a circle, a triangle, or other shapes.

[0068] refer to Figure 6 and Figure 7 As shown, the first magnet 210 can be rectangular in shape, with a width of L1 and a length that can be designed according to actual needs. The interval between adjacent first magnets 210 is L2, and L1 and L2 can be equal to ensure a uniform magnetic field. The first magnet 210 can also be square, and multiple first magnets 210 can be arranged in multiple rows and columns to ensure a uniform magnetic field within the preservation chamber 100. The specific shape and arrangement can be designed according to the specific application scenario, and this embodiment does not impose specific limitations on this.

[0069] Optionally, when there are multiple first magnets 210, the first coil 220 can be provided on the outside of some of the first magnets 210 (for example, only on the middle of the first magnets 210), or the first coil 220 can be provided on the outside of all the first magnets 210. The specific design can be made according to the magnetic field preservation requirements. The second magnet 310 can be set with reference to the first magnet 210. This embodiment does not make specific limitations on this.

[0070] In one alternative implementation, refer to Figure 5 As shown, there are multiple first magnets 210, which are arranged at intervals, and the magnetic poles of adjacent first magnets 210 are arranged in opposite directions.

[0071] The arrangement of multiple first magnets 210 at intervals helps to form a uniform and stable magnetic field, thereby more effectively covering the entire preservation area. Furthermore, the opposite orientation of the magnetic poles of adjacent first magnets 210 allows magnetic field lines to form closed loops between them. This means the magnetic field lines of adjacent first magnets 210 overlap in the space between them, enhancing the local magnetic field strength and making the magnetic field within the preservation compartment 100 more concentrated, which is beneficial for improving the preservation effect of food.

[0072] In one alternative implementation, refer to Figure 3 As shown, there are multiple second magnets 310, which are arranged at intervals and the magnetic poles of adjacent second magnets 310 are arranged in opposite directions, which can also enhance the local magnetic field strength and improve the preservation effect.

[0073] In one alternative implementation, refer to Figure 1 As shown, multiple first magnets 210 are arranged at intervals, with gaps 211 between adjacent first magnets 210, and second magnets 310 are arranged corresponding to the gaps 211.

[0074] For example, referring to the accompanying drawings, the first magnet 210 and the second magnet 310 are alternately arranged in the projection on the horizontal plane. The arrangement of the second magnet 310 helps to enhance the magnetic field in the weak magnetic field area formed by the first magnet 210, ensuring that the magnetic field of the entire preservation space is more uniform. This helps to reduce the problem of uneven food preservation caused by uneven magnetic field, thereby extending the freshness and shelf life of the food.

[0075] For example, the number of the first magnet 210 and the second magnet 310 can both be 3, 4 or more. Optionally, the number of the first magnet 210 and the second magnet 310 is an odd number.

[0076] In an optional embodiment, both the first magnet 210 and the second magnet 310 are provided with at least one of the following: a foolproof notch 212, a foolproof protrusion, or a foolproof coating.

[0077] For example, such as Figure 6 As shown, a foolproof notch 212 or a foolproof protrusion can be provided at a specific location on the first magnet 210, in conjunction with the shape of the mounting groove 241, to ensure that the first magnet 210 can only be installed in the correct direction and position, thereby preventing the defect of reversed magnetic pole orientation due to incorrect orientation during installation. Similarly, different colors or markings can be applied to specific areas of the first magnet 210 to visually guide installers to correctly install the first magnet 210, helping operators quickly identify the correct installation direction and position of the first magnet 210.

[0078] In one alternative implementation, refer to Figure 2 As shown, the first cover plate 240 is provided with a wire block 244, which is used to guide and fix the wires of the first coil 220, ensuring that the wires are laid out in an orderly manner according to the predetermined route, reducing mutual interference between wires, facilitating installation and maintenance, and also providing a certain degree of support and protection.

[0079] Optionally, the structure or shape of the wire block 244 can be a fixing clip, wire groove, hook, etc., and this embodiment does not specifically limit it.

[0080] In one alternative implementation, refer to Figure 2 As shown, the first cover plate 240 is provided with a wire hole 245, through which the wire of the first coil 220 is passed, allowing the wire of the first coil 220 to pass smoothly through and be connected to the power source to supply power to the first coil 220.

[0081] It should be noted that the second magnetic field component 300 can also be fixed to the preservation equipment or to the preservation chamber 100. The structure of the second magnetic field component 300, the specific setting method, and the layout and connection method of the second magnet 310 can be referred to the corresponding first magnetic field component 200 and first magnet 210 in the above embodiments. This embodiment will not be described in detail.

[0082] In one alternative implementation, refer to Figure 1 and Figure 8 As shown, the second magnetic field assembly 300 includes a second cover plate 320, which is installed at the bottom of the fresh food compartment 100, and the second magnet 310 is located between the fresh food compartment 100 and the second cover plate 320. That is, the second magnetic field assembly 300 can be fixed at the bottom of the fresh food compartment 100 and move with the fresh food compartment 100.

[0083] For example, the fresh food compartment 100 is provided with a slot, and the second cover plate 320 is provided with a plug-in part. The second magnet 310 is installed on the bottom plate of the fresh food compartment 100 or the second cover plate 320. Then, the plug-in part is inserted into the slot to fix and seal the second magnet 310 between the fresh food compartment 100 and the second cover plate 320. This simplifies the installation structure and steps of the second magnet 310, requires no additional tools or complicated operations, and improves the ease of installation of the second magnet 310.

[0084] In one alternative implementation, refer to Figure 8 As shown, a heat-conducting plate 110 is provided at the bottom of the fresh food compartment 100. The height of the outer edge of the heat-conducting plate 110 is lower than the height of the middle area of ​​the heat-conducting plate 110, and a water storage tank 111 is formed in the middle of the heat-conducting plate 110.

[0085] In this embodiment, the heat-conducting plate 110 is made of a material with excellent thermal conductivity (such as aluminum). The main function of the heat-conducting plate 110 is to promote a uniform temperature distribution within the freshness compartment 100. Since the cooling system inside the refrigerator may cause some areas to be colder than others, the heat-conducting plate 110, with its excellent thermal conductivity, helps to balance these temperature differences. The design of the heat-conducting plate 110 corresponds to the uniform magnetic field loop formed at the bottom, ensuring a dual uniform distribution of temperature and magnetic field, thereby improving the freshness preservation effect.

[0086] Furthermore, a water storage tank 111 is formed in the middle of the heat-conducting plate 110. The purpose of the water storage tank 111 is to collect and store moisture that may be generated on the surface of the food or during the food storage process, such as the natural juice of vegetables and fruits.

[0087] Moisture released from the food is directed to the central area, rather than flowing to other parts of the drawer, thus keeping the interior of the fresh food compartment 100 dry. The water reservoir 111 effectively collects moisture, preventing it from directly contacting the bottom or sides of the fresh food compartment 100, reducing potential damage to the fresh food compartment 100, and also preventing bacterial growth, helping to keep the interior of the fresh food compartment 100 clean and reducing cleaning and maintenance workload.

[0088] In an alternative implementation, the outer side of the heat-conducting plate 110 is provided with a clearance notch.

[0089] For example, the shape and size of the heat transfer plate 110 can be substantially adapted to the shape and size of the fresh-keeping compartment 100, such as a fresh-keeping drawer. The clearance notch makes it easier for the user to operate when placing the heat transfer plate 110 into or removing it from the fresh-keeping compartment 100. The clearance notch can also serve as a grip, allowing the user to hold the heat transfer plate 110 stably, thus improving user convenience in actual use.

[0090] In one alternative implementation, refer to Figure 3 As shown, the top of the fresh food compartment 100 is equipped with a sealing cover 120, which keeps the fresh food compartment 100 in a relatively sealed state to maintain the humidity inside the compartment, thereby achieving a moisturizing effect. By ensuring that the sealing cover 120 is tightly closed, the loss of moisture inside the fresh food compartment 100 can be effectively prevented, maintaining a suitable humidity environment. When used in conjunction with a magnetic field, it is even more beneficial for the preservation of food.

[0091] The preservation compartment structure provided in this application includes a preservation compartment 100, a first magnetic field component 200, and a second magnetic field component 300, which are respectively disposed on opposite sides of the preservation compartment 100. The first magnetic field component 200 includes a first magnet 210 and a first coil 220, with the first coil 220 surrounding the outer side of the first magnet 210. And / or, the second magnetic field component 300 includes a second magnet 310 and a second coil, with the second coil surrounding the outer side of the second magnet 310. By distributing the first magnetic field component 200 and the second magnetic field component 300 on opposite sides of the preservation compartment 100, a uniform distribution of the magnetic field within the preservation compartment 100 is ensured, reducing magnetic field dead zones. Furthermore, the coil surrounding the outer side of the magnet generates an additional magnetic field that superimposes on the magnet's own magnetic field, enhancing the overall magnetic field strength and improving the preservation effect on food.

[0092] Secondly, this application also provides a preservation device, which includes a preservation chamber structure as described in the above embodiment. The preservation chamber 100 of the above embodiment is used to preserve food, thereby improving the preservation effect and reducing the preservation cost.

[0093] refer to Figure 9 and Figure 10 As shown, the fresh-keeping compartment 100 can be a fresh-keeping drawer, and the fresh-keeping equipment can be a household appliance such as a refrigerator, freezer, or display case. Taking a refrigerator as an example, the refrigerator can be a single-door refrigerator or a multi-door refrigerator, and the refrigerator can be equipped with one or more fresh-keeping drawers, which can be arranged side by side. Optionally, a decorative panel is provided on the front side of the fresh-keeping drawer, and the decorative panel can be glass to improve the aesthetics of the fresh-keeping drawer.

[0094] It is understood that if the structure of the preservation chamber has the beneficial effects of the above embodiments, then the preservation equipment will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and this embodiment will not repeat it.

[0095] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should all be covered within the protection scope of this application.
