[0003] In view of this, embodiments of this application provide a cabinet door panel, a storage device, and a refrigerator to solve the above-mentioned technical problems.

[0004] According to a first aspect of this application, an embodiment of this application provides a cabinet door panel applied to a storage device. The storage device includes a cabinet with storage space, and the cabinet door panel is connected to the cabinet and used to cover the storage space. The cabinet door panel includes a composite substrate, which includes a stone-plastic substrate layer and a magnetic layer stacked on top of each other. When the cabinet door panel covers the storage space, the magnetic layer is disposed on the side of the stone-plastic substrate layer facing away from the storage space.

[0005] In some embodiments, the magnetic layer is a stone-plastic magnetic plate.

[0006] In some embodiments, the stone-plastic magnetic plate includes magnetic powder.

[0007] In some embodiments, the thickness of the magnetic layer is greater than or equal to 0.8 mm and less than or equal to 3 mm.

[0008] In some embodiments, the thickness of the stone-plastic substrate layer is greater than or equal to 0.8 mm and less than or equal to 4 mm.

[0009] In some embodiments, the cabinet door panel includes a first protective layer attached to one side of the composite substrate. When the cabinet door panel covers the storage space, the first protective layer is disposed on the side of the composite substrate opposite to the storage space.

[0010] In some embodiments, the cabinet door panel further includes a second protective layer, which is attached to the surface of the first protective layer. Both the first and second protective layers are plastic layers.

[0011] In some embodiments, both the second protective layer and the first protective layer are light-transmitting layers. The first protective layer has a first pattern, and the second protective layer has a second pattern, which is different from the first pattern.

[0012] In some embodiments, the cabinet door panel further includes a connecting layer, which is stacked with the substrate. When the cabinet door panel covers the storage space, the connecting layer is disposed on the substrate and on the side facing the storage space.

[0013] According to a second aspect of this application, an embodiment of this application provides a storage device, which includes a cabinet and a cabinet door panel of any of the aforementioned items.

[0026] Please see Figure 1 This application provides a cabinet door panel 100, which is applied to a storage device 200 (see reference). Figure 2The cabinet door panel 100 is used to close the storage device 200 and protect the internal components or internal stored items of the storage device 200. The internal components 201 can be electronic or non-electronic, and can be set according to actual usage requirements. This embodiment does not impose specific restrictions on this.

[0027] Please see Figure 2 This application embodiment also provides a storage device 200 for storing the aforementioned internal components 201. The storage device 200 includes a cabinet 202 and the aforementioned cabinet door panel 100. The cabinet 202 is the main structure of the storage device 200, and it is provided with a storage space 203 for storing the aforementioned internal components 201. This embodiment does not limit the specific type of the storage device 200.

[0028] As an example, the storage device 200 can be a freezer, which is used to store frozen food or medicine, etc., and this embodiment does not impose specific limitations on it. The freezer has a cabinet 202, which has openings and storage space 203 that are interconnected. The door panel 100 is used to connect to the cabinet 202 and cover the storage space 203 to reduce the leakage of cold air from the freezer, thereby maintaining a low temperature environment inside the freezer and reducing energy consumption.

[0029] As another example, the storage device 200 can be a warming cabinet, which is used to keep food, medicine, etc. warm. The warming cabinet may include the cabinet body 202 mentioned above and the cabinet door panel 100. The cabinet door panel 100 is connected to the cabinet body 202 and covers the storage space 203 to reduce the loss of internal temperature of the warming cabinet, thereby improving the heat preservation effect of the warming cabinet.

[0030] As another example, the storage device 200 can also be a storage cabinet, which is used to store items such as clothing, toys, books, etc. This embodiment does not impose specific limitations on this. The storage cabinet includes the cabinet body 202 mentioned above and the cabinet door panel 100. The cabinet door panel 100 is connected to the cabinet body 202 and covers the storage space 203 to protect the items inside the storage cabinet from dust, moisture and other external factors, and to keep the items clean and dry.

[0031] It is understood that the storage device 200 may include different functional components depending on its intended use. For example, in some embodiments, the storage device 200 may also include a cooling device 204, which is disposed in the storage space 203 to reduce the temperature inside the storage space 203, thereby providing a suitable storage environment. In other embodiments, the storage device 200 may include a heating device, which is disposed in the storage space 203 to raise or maintain the temperature inside the storage space 203. Of course, the storage device 200 may also include other components, such as sterilization devices, heat sinks, etc., and this embodiment does not impose specific limitations on these components.

[0032] It should be noted that the storage device 200 is not limited to the freezers, warming cabinets, and storage cabinets mentioned above; it can also be a disinfection cabinet, refrigerator, or other container with internal space for storing items. This embodiment does not limit the specific type of the storage device 200. For ease of description, a refrigerator is used as an example to illustrate the storage device 200 in this embodiment.

[0033] Please see Figure 3 This embodiment also provides a refrigerator 300, which includes an outer shell 2021 and an insulated inner liner 2022. The insulated inner liner 2022 is connected to the outer shell 2021 and together with the outer shell 2021 forms the aforementioned cabinet 202. Specifically, the outer shell 2021 is generally cuboid in shape. The outer shell 2021 can be a metal shell, a plastic shell, or a ceramic shell; this embodiment does not impose any specific limitations on this. The outer shell 2021 has a mounting cavity, and the insulated inner liner 2022 is disposed within the mounting cavity and connected to the outer shell 2021. The insulated inner liner 2022 maintains a low-temperature environment inside the refrigerator 300, isolates the entry of external heat, and ensures the cooling effect inside the refrigerator 300. The insulated inner liner 2022 can specifically be polyurethane foam, which helps to insulate heat and reduce heat exchange to improve the cooling effect.

[0034] The refrigerator 300 also includes a door panel 310, which is movably connected to the outer shell 2021 and used to cover the storage space 203 to prevent cold air leakage. Specifically, the door panel 310 includes an insulation board 311 and the aforementioned door panel 100. When the door panel 310 covers the storage space 203, the door panel 100 covers the side of the insulation board 311 facing away from the storage space 203. The size of the insulation board 311 can be matched with the door panel 100 to further insulate against heat exchange and improve the cooling effect. By setting the insulation board 311 and the door panel 100 to form a double-layer structure, on the one hand, better insulation effect can be provided, reducing the leakage of cold air and the entry of external heat, thereby improving the energy efficiency of the refrigerator 300; on the other hand, the double-layer structure provides additional support, enhancing the stability and durability of the door panel 310 and reducing damage caused by frequent opening and closing of the door.

[0035] Please refer to it again. Figure 1 and Figure 2 This embodiment provides a cabinet door panel 100, which is applied to the aforementioned storage device 200 or refrigerator 300. The cabinet door panel 100 is connected to the aforementioned cabinet body 202 and is used to cover the storage space 203. In this embodiment, the cabinet door panel 100 includes a composite substrate 11, which includes a stone-plastic substrate layer 111 and a magnetic layer 112, which are stacked on top of each other. When the cabinet door panel 100 covers the storage space 203, the magnetic layer 112 is disposed on the side of the stone-plastic substrate layer 111 facing away from the storage space 203.

[0036] The cabinet door panel 100 has a magnetic attraction effect by setting a magnetic layer 112 in the composite substrate 11, which facilitates the magnetic attraction of refrigerator magnets and other magnetic accessories, thereby improving the functionality and aesthetics of the cabinet door panel 100. The composite substrate 11 also includes a stone-plastic substrate layer 111, which has high hardness and can improve the durability and service life of the cabinet door panel 100. Furthermore, when the cabinet door panel 100 covers the receiving space of the cabinet body 202, the magnetic layer 112 is set on the side of the stone-plastic substrate layer 111 facing away from the storage space 203. On the one hand, this gives the outer surface of the cabinet door panel 100 a strong magnetic attraction ability, improving the magnetic attraction effect; on the other hand, it can reduce the interference of the magnetic field on the interior of the storage space 203.

[0037] The specific components and structure of the cabinet door panel 100 will be introduced one by one below.

[0038] Please see Figures 1 to 3In this embodiment, the cabinet door panel 100 is generally plate-shaped and is used to cover the storage space 203 of the storage device 200 to prevent cold air leakage and improve the cooling effect of the refrigerator 300. Specifically, the cabinet door panel 100 is a stone plastic composite panel (SPC), which is a formaldehyde-free, mildew-proof, fire-resistant, and waterproof decorative panel made from raw materials such as calcium powder and resin through plasticizing and extrusion. It can effectively improve the functionality and aesthetics of the storage device 200. The cabinet door panel 100 specifically includes a composite substrate 11, which is disposed on the outside of the storage device 200 or the refrigerator 300. "Outer side" can be understood as the side facing the user. The composite substrate 11, as the main structure of the cabinet door panel 100, is generally flat, which allows for maintaining the flatness and aesthetics of the storage device 200 while ensuring good structural strength. When the cabinet door panel 100 is installed and used, the magnetic components can be attracted to the surface of the cabinet door panel 100 based on the magnetic attraction of the composite substrate 11, which improves the durability and functionality of the cabinet door panel 100.

[0039] Specifically, the magnetic components can be magnetic decorative paintings, refrigerator magnets, etc. These decorative paintings or refrigerator magnets are attracted to any position on the surface of the cabinet door panel 100 under the magnetic attraction of the composite substrate 11, satisfying the user's decorative needs and thus improving the aesthetics of the cabinet door panel 100. Magnetic components can also be magnetic storage items, such as metal hooks or metal storage boxes. These metal hooks or metal storage boxes are attracted to any position on the surface of the cabinet door panel 100 under the magnetic attraction of the magnetic composite layer. The metal hooks or metal storage boxes can be used to hang or store kitchen utensils, garbage bags, or other small items, further increasing the storage space 203 of the storage device 200 and facilitating the user's retrieval and placement of items. Magnetic components can also be magnetic functional items, such as metal wall clocks or metal chalkboard stickers, allowing users to easily check the time or write notes, improving the user experience. It is understood that the magnetic components attracted to the cabinet door panel 100 are not limited to the items mentioned above; other magnetic components can also be used, depending on actual usage needs. This satisfies users' decorative needs or ease of use for the cabinet door panel 100, and improves the aesthetics and functionality of the refrigerator 300.

[0040] In this embodiment, the composite substrate 11 includes a stone-plastic substrate layer 111 and a magnetic layer 112, which are stacked on top of each other. Under the magnetic attraction of the magnetic layer 112, magnetic items such as refrigerator magnets can be adsorbed onto the outer surface of the cabinet door panel 100, serving a decorative purpose while being easy to adsorb and remove, thus improving the user experience.

[0041] The stone-plastic substrate layer 111 serves as a supporting structure to provide the composite substrate 11 with a certain structural strength, thereby improving the durability of the cabinet door panel 100. The stone-plastic substrate layer 111 is flat and is a high-molecular composite material formed by plasticizing stone and plastic. It possesses environmentally friendly, waterproof, fireproof, and strong deformation resistance properties, and is also rust-resistant, easy to clean, and has good heat insulation properties. This extends the service life of the cabinet door panel 100 and maintains its aesthetic appearance for a longer period. As an example, the stone-plastic substrate layer 111 can be specifically composed of polyvinyl chloride resin powder, carbonated cement, stabilizer, lubricant, PE wax, chlorinated polyethylene, acrylate, colorant, etc. It is understood that the stone-plastic substrate layer 111 can also include other stones or plastics; this embodiment does not limit the specific composition and proportions of the stone-plastic substrate layer 111.

[0042] In this embodiment, the thickness of the stone-plastic substrate layer 111 is set to be greater than or equal to 0.8 mm and less than or equal to 4 mm. This thickness provides high strength, ensuring the composite substrate 11 has sufficient strength to support the cabinet door panel 100 while maintaining overall stability. As an example, the thickness of the stone-plastic substrate layer 111 can be 0.8 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, or 4 mm; this embodiment does not impose specific limitations on this. It should be noted that the thickness of the stone-plastic substrate layer 111 can also be other values, and can be set according to actual usage requirements. Furthermore, the stone-plastic substrate layer 111 can be a single-layer structure or a multi-layer structure. For example, multiple stone-plastic substrate layers 111 can be stacked together to form a whole, with a total thickness of greater than or equal to 0.8 mm and less than or equal to 4 mm. Adjacent stone-plastic substrate layers 111 can be connected by adhesive bonding or extrusion. The thickness of the multiple stone-plastic substrate layers 111 can be the same or different. This embodiment does not limit the number of layers in the multilayer structure, the thickness of each stone-plastic substrate layer 111, or the connection method of adjacent stone-plastic substrate layers 111.

[0043] The magnetic layer 112 serves as a magnetic attraction structure to give the composite substrate 11 magnetic attraction capabilities, thereby improving the functionality of the cabinet door panel 100. The magnetic layer 112 can be a magnetic metal layer or a magnetic composite layer. For example, the magnetic layer 112 can be a zinc-plated layer, a metallic iron layer, or a metal compound layer, or it can be a magnetic composite layer containing both metals and non-metals. In this embodiment, the magnetic layer 112 is a stone-plastic magnetic board, which may include magnetic powder. As an example, the stone-plastic magnetic board is a composite material made from raw materials such as calcium powder and resin, along with magnetic powder, through plasticization. It has characteristics such as environmental friendliness, high strength, strong stability, and good magnetic properties, which can improve the service life and functionality of the cabinet door panel 100. Specifically, the magnetic powder can be at least one of iron powder, iron oxide powder, and chromium dioxide magnetic powder; this embodiment does not impose specific limitations on this.

[0044] Please see Figure 4 In this embodiment, the magnetic layer 112 and the stone-plastic substrate layer 111 are stacked on top of each other. Specifically, the magnetic layer 112 can be disposed on the outer surface of the stone-plastic substrate layer 111 to facilitate better adsorption of magnetic components. That is, when the cabinet door panel 100 covers the accommodating space of the cabinet body 202, the magnetic layer 112 is disposed on the side of the stone-plastic substrate layer 111 away from the storage space 203. On the one hand, this enables the outer surface of the cabinet door panel 100 to have a strong magnetic adsorption capacity, improving the magnetic adsorption effect; on the other hand, it can reduce the interference of the magnetic field on the interior of the storage space 203. For example, when the storage device 200 stores electronic components, it can reduce the magnetization of the electronic components by the magnetic field to ensure the performance of the electronic components.

[0045] It should be noted that in some embodiments, the magnetic layer 112 may also be disposed between the stone-plastic substrate layer 111 and the cabinet 202, that is, the magnetic layer 112 is disposed on the side of the stone-plastic substrate layer 111 facing the accommodating space of the cabinet 202. Thus, the magnetic layer 112 is not directly exposed to the outside environment, which can reduce wear and contamination during daily use, making the cabinet door panel 100 easier to maintain and clean. Furthermore, since the magnetic layer 112 is disposed on the side of the stone-plastic substrate layer 111 facing the accommodating space, the adsorption capacity of the magnetic layer 112 can be directly utilized to firmly fix the cabinet door panel 100 to the cabinet 202, improving the sealing performance between the cabinet door panel 100 and the cabinet 202.

[0046] In this embodiment, the thickness of the magnetic layer 112 is set to be greater than or equal to 0.8 mm and less than or equal to 3 mm. This thickness provides sufficient magnetic attraction for magnetic components and reduces the production cost of the cabinet door panel 100. For example, the thickness of the magnetic layer 112 can be 0.8 mm, 1 mm, 1.5 mm, 2 mm, or 3 mm; this embodiment does not impose specific limitations on this. It should be noted that the thickness of the magnetic layer 112 can also be other values, which can be set according to actual usage requirements. Furthermore, the magnetic layer 112 can be a single-layer structure or a multi-layer structure. For example, multiple magnetic layers 112 can be stacked to form a whole, with a total thickness of greater than or equal to 0.8 mm and less than or equal to 3 mm. Adjacent magnetic layers 112 can be connected by adhesive bonding or extrusion. The thickness of the multiple magnetic layers 112 can be the same or different. This embodiment does not limit the number of layers in the multi-layer magnetic layer 112, the thickness of each magnetic layer 112, or the connection method between adjacent magnetic layers 112.

[0047] In this embodiment, since the composite substrate 11 is directly exposed to the outside of the storage device 200 or refrigerator 300, the cabinet door panel 100 may include a first protective layer 12 to improve the service life of the composite substrate 11. The first protective layer 12 is used to protect the composite substrate 11 from damage caused by the external environment, such as scratches and corrosion, thereby extending the service life of the cabinet door panel 100 and ensuring a good appearance. The first protective layer 12 is attached to one side of the surface of the composite substrate 11, specifically, when the cabinet door panel 100 covers the storage space 203, the first protective layer 12 is located on the side of the composite substrate 11 facing away from the storage space 203. As one installation example, the stone-plastic substrate layer 111, the magnetic layer 112, and the first protective layer 12 are stacked sequentially. As another installation example, the magnetic layer 112, the stone-plastic substrate layer 111, and the first protective layer 12 are stacked on top of each other. In the above installation examples, the first protective layer 12 is always located on the outermost side, that is, the side facing the user. The first protective layer 12 may be a rubber layer or a woven layer, etc., which can reduce wear on the composite substrate 11. The first protective layer 12 can also be a plastic film layer, such as a PVC plastic film or a PET plastic film. This embodiment does not impose any specific limitations on this.

[0048] In some embodiments, the first protective layer 12 can also serve as a decorative layer to further enhance the aesthetics of the cabinet door panel 100. Specifically, the first protective layer 12 is provided with a first pattern 121. This embodiment does not impose specific limitations on the specific type of the first pattern 121 or its distribution position on the first protective layer 12. For example, the first pattern 121 can be at least any one of plants, animals, people, or celestial bodies. The first pattern 121 can be distributed all over the surface of the first protective layer 12 or partially disposed on the surface of the first protective layer 12 to enhance the decorative effect. It is understood that the first pattern 121 can be disposed on the first protective layer 12 by means of embossing, screen printing, spraying, etc. Of course, the first pattern 121 can also be a textured structure, such as a beaded structure or a striped structure. This embodiment does not impose specific limitations on this. By setting a textured structure, not only can the aesthetics of the cabinet door panel 100 be improved, but the wear resistance of the first protective layer 12 can also be increased, preventing fingerprints and scratches, and improving the durability of the product.

[0049] Furthermore, in some embodiments, the cabinet door panel 100 may also include a second protective layer 13, which is used to further improve the wear resistance of the cabinet door panel 100. The second protective layer 13 is specifically attached to the surface of the first protective layer 12, specifically on the side of the first protective layer 12 facing away from the composite substrate 11, or between the first protective layer 12 and the composite substrate 11; this embodiment does not impose specific limitations on this. The second protective layer 13 can be a rubber layer, a woven layer, or a plastic film layer, such as a PVC plastic film or a PET plastic film. By setting the above-mentioned first protective layer 12 and second protective layer 13, a double-layer protective structure can be formed, enhancing the overall durability and protective performance of the cabinet door panel 100.

[0050] In some embodiments, the second protective layer 13 may also be provided with a second pattern 131, which is different from the first pattern 121. The two patterns are superimposed to further enhance the decorative effect of the cabinet door panel 100. This embodiment does not impose specific limitations on the specific type of the second pattern 131 or its distribution position on the second protective layer 13. It is understood that the second pattern 131 can be a texture structure or an image pattern, and can be set according to actual usage requirements. Specifically, when the second protective layer 13 is superimposed on the side of the first protective layer 12 facing away from the composite substrate 11, the second protective layer 13 may have a light-transmitting structure. The second pattern 131 is disposed on the second protective layer 13, and the first pattern 121 is disposed on the surface of the first protective layer 12 facing the second protective layer 13. Thus, the first pattern 121 can be mapped onto the surface of the second pattern 131 through the light-transmitting structure and superimposed with the second pattern 131 to form an appearance pattern. As a specific example, the light-transmitting structure is a light-transmitting layer, that is, the second protective layer 13 is a light-transmitting plastic. When the first protective layer 12 and the second protective layer 13 are stacked, the first pattern 121 can be exposed on the outer surface of the cabinet door panel 100 through the light-transmitting plastic, and superimposed with the second pattern to form an appearance pattern. In other embodiments, the light-transmitting structure can be a light-transmitting hole that penetrates the second protective layer 13, so that the first pattern 121 can be exposed in the light-transmitting hole, making it convenient for the user to directly view the first pattern 121 and the second pattern 131. The two are superimposed to form the appearance pattern viewed by the user. For example, the first pattern 121 can be a nebula pattern, and the second pattern 131 can be a star pattern. The star pattern and the nebula pattern together form a starry sky effect, which can create a three-dimensional misalignment effect to further improve the decorative effect of the cabinet door panel 100. It should be noted that this embodiment does not impose specific limitations on the aperture size, appearance shape, distribution density, and arrangement of the light-transmitting hole on the second protective layer 13. It can be understood that different light-transmitting holes will form different appearance effects, and can be set according to actual needs.

[0051] In another embodiment, when the second protective layer 13 is stacked between the first protective layer 12 and the composite substrate 11, that is, when the second protective layer 13 is disposed inside the first protective layer 12, the first protective layer 12 may have the aforementioned light-transmitting structure. The second pattern 131 is disposed on the surface of the second protective layer 13 facing the first protective layer 12, so that the second pattern 131 can be mapped onto the surface of the first pattern 121 through the light-transmitting structure and superimposed with the first pattern 121 to form an appearance pattern.

[0052] It should be noted that, in the above embodiments, when either the first protective layer 12 or the second protective layer 13 is located inside the other, the inner layer may or may not have a light-transmitting structure, and this embodiment does not impose specific limitations on this. For example, when both the first protective layer 12 and the second protective layer 13 are light-transmitting layers, the first pattern 121 and the second pattern 131 can be respectively set at any position on the corresponding first protective layer 12 and the corresponding second protective layer 13 to improve the sense of layering of the appearance pattern.

[0053] In some embodiments, the first pattern 121 and / or the second pattern 131 may include multiple sub-patterns (not shown in the figures), with at least two different sub-patterns, thereby enabling the formation of various aesthetic effects. This embodiment does not impose specific limitations on the specific style, arrangement, or shape and size of the multiple sub-patterns. As an example only, the first pattern 121 includes multiple first sub-patterns (not shown in the figures), which are sequentially arranged on the first protective layer 12 to form the first pattern 121. One of the first sub-patterns may be a wavy pattern, and another may be a striped pattern. As an example, the second pattern 131 includes multiple second sub-patterns (not shown in the figures), which are sequentially arranged on the second protective layer 13 to form the second pattern 131. One of the second sub-patterns may be a floral pattern, and another may be an animal pattern. By setting the aforementioned multiple sub-patterns, various aesthetic effects can be further formed to further enhance the decorative effect of the cabinet door panel 100.

[0054] Please see Figure 1 and Figure 5 In this embodiment, the cabinet door panel 100 may further include a connecting layer 14. The connecting layer 14 is used to fix the cabinet door panel 100 and the cabinet body 202, which helps to maintain the connection stability and flatness of the cabinet door panel 100 during the use of the refrigerator 300, especially when subjected to external forces or temperature changes. As an example, the connecting layer 14 and the composite substrate 11 are stacked. When the cabinet door panel 100 covers the storage space 203, the connecting layer 14 is located on the side of the composite substrate 11 facing the storage space 203. As a specific installation example, the connecting layer 14, the stone-plastic substrate layer 111, and the magnetic layer 112 are stacked in sequence. As another installation example, the connecting layer 14, the magnetic layer 112, and the stone-plastic substrate layer 111 are stacked in sequence. It should be noted that the connecting layer 14 is always located on the innermost side, that is, the side of the cabinet door panel 100 that is away from the user when installed and used.

[0055] The connecting layer 14 can specifically be an adhesive layer, with the composite substrate 11 and the cabinet 202 respectively bonded to both sides of the adhesive layer. The adhesive layer can be a backing paint layer. The connecting layer 14 can also be an adhesive strip, with the composite substrate 11 connected to the cabinet 202 via the adhesive strip. The connecting layer 14 can also be glue, which adheres between the composite substrate 11 and the cabinet 202. Further, in some embodiments, the glue is wrapped around the composite substrate 11, so that the stone-plastic substrate layer 111 and the magnetic layer 112 are completely wrapped inside the glue, providing additional physical protection for the stone-plastic substrate layer 111 and the magnetic layer 112 and further improving the connection stability between them.

[0056] In summary, this application provides a cabinet door panel 100, which is applied to a storage device 200, including a cabinet body 202. In this embodiment, the cabinet door panel 100 has a magnetic attraction effect by setting a magnetic layer 112 in the composite substrate 11, which facilitates the attraction of magnetic items such as refrigerator magnets, thereby improving the functionality and aesthetics of the cabinet door panel 100. The composite substrate 11 also includes a stone-plastic substrate layer 111, which has high hardness and can improve the durability and service life of the cabinet door panel 100. Furthermore, when the cabinet door panel 100 covers the accommodating space of the cabinet body 202, the magnetic layer 112 is disposed on the side of the stone-plastic substrate layer 111 facing away from the storage space 203. On the one hand, this enables the outer surface of the cabinet door panel 100 to have a strong magnetic attraction ability, improving the magnetic attraction effect; on the other hand, it can reduce the interference of the magnetic field on the interior of the storage space 203.
