[0042] like Figures 1 to 7 As shown, the present application discloses a refrigerator interior decoration panel, including a decorative back panel 4, which is applied to a storage cavity 3 inside the refrigerator, wherein the decorative back panel 4 includes:

[0043] The transparent substrate layer 401 is arranged in a rectangular or oblong shape as a whole;

[0044] The pattern layer 402 is in the form of a paint film attached or painted on the side surface of the transparent substrate layer 401 . The pattern layer 402 covers one of the largest side surfaces of the transparent substrate layer 401 .

[0045] The refrigerator interior decorative panel disclosed in the present application includes a at least two-layer structural design consisting of a transparent substrate layer 401 and a pattern layer 402. The transparent substrate layer 401 serves as the basis of the decorative back panel 4, providing good light transmittance and structural support. The pattern layer 402 is fixed to one of the largest sides of the transparent substrate layer 401 by means of paint film attachment or paint painting, forming a colorful pattern or design element. This structure enables the pattern layer 402 to penetrate the transparent substrate layer 401 and be reflected in the storage cavity 3 inside the refrigerator, thereby forming a bright and beautiful visual effect inside the refrigerator, meeting the user's decorative needs for the interior space of the refrigerator; at the same time, since the pattern layer 402 is closely attached to the transparent substrate layer 401, the durability and stability of the pattern are guaranteed, and it is not easy to fade or peel off.

[0046] The refrigerator interior decorative panel described in the present application can significantly enhance the decorative effect and aesthetics of the interior of the refrigerator. The rich colors and design elements of the pattern layer 402 not only add vitality to the interior of the refrigerator, but can also be customized according to the personalized needs of users to meet the aesthetic preferences of different users; at the same time, the light transmittance of the transparent substrate layer 401 enables the pattern layer 402 to present a good visual effect under different lighting conditions, which not only ensures practicality but also takes into account aesthetics; in addition, the decorative back panel 4 is easy to install and replace, which is convenient for users to update according to personal preferences or seasonal changes and other needs, thereby increasing the fun and flexibility of use.

[0047] As a preferred example of the present application, the transparent substrate layer 401 is made of acrylic or glass. The transparent substrate layer 401 is made of acrylic or glass. Both materials have good transparency and can allow light to pass through smoothly. This design not only maintains the integrity and aesthetics of the decorative backboard, but also fully utilizes the transparent properties of the material to achieve a perfect fusion of light and pattern, ensuring the clear display of the pattern layer 402, making the pattern colorful and well-defined, greatly enhancing the visual beauty of the refrigerator interior; secondly, both materials have good durability and chemical stability, and can resist stains, scratches and other damage that may be encountered in daily use, thereby extending the service life of the decorative backboard; in addition, acrylic and glass have excellent processing performance, and it is easy to produce a transparent substrate layer 401 that meets various size and shape requirements, thereby meeting the personalized decoration needs of different refrigerator models.

[0048] As a preferred example of the present application, the pattern layer 402 adopts a single color or multi-color setting with color gradient from top to bottom. As a specific example of the present application, the pattern layer 402 adopts a single color design, and the pattern layer 402 adopts a gradient silk screen setting with white on top and green on the bottom, and the green at the bottom is emerald-like in color. Alternatively, the pattern layer 402 adopts a gradient design of multiple colors from top to bottom, such as a gradient from light blue to dark blue, or from pink to purple. Such a design can add a lively and warm atmosphere to the interior of the refrigerator; or the pattern layer 402 imitates elements in nature, such as ocean waves (gradually changing from blue to white), sunrise and sunset (gradually changing from orange-red to purple), forest trees (gradually changing from green to brown), etc. These designs can not only enhance the aesthetics, but also make people feel the tranquility and harmony of nature.

[0049] By using silk-screen technology to achieve the color gradient design of pattern layer 402, different shades of color are gradually printed on transparent substrate layer 401. When light penetrates the transparent substrate layer and illuminates the pattern layer, the color gradient effect is refracted and reflected by the light, creating a rich visual layering and a unique visual effect. The gradient design also creates a sense of spatial extension, making the interior of the refrigerator appear more spacious and bright.

[0050] As a preferred example of this application, a protective layer 404 is provided on the side of the pattern layer 402 away from the transparent substrate layer 401, and the protective layer 404 covers the pattern layer 402. In this example, the protective layer 404 and the transparent substrate layer 401 are designed and formed using the same structure and materials. The transparent substrate layer 401 and the protective layer 404 sandwich the pattern layer 402, forming a sandwich pattern. This design not only enhances the stability of the overall structure but also effectively protects the pattern layer 402 from physical damage such as external wear and scratches. At the same time, because the protective layer 404 and the transparent substrate layer 401 are made of the same material, their light transmittance remains consistent, ensuring that the visual effect of the pattern layer 402 is not affected.

[0051] By providing the protective layer 404, the overall durability of the decorative backboard is significantly improved, the pattern layer 402 is better protected, and the service life of the decorative backboard is extended. At the same time, the sandwich structure design also makes the display effect of the pattern layer 402 more stable and less likely to change due to external factors.

[0052] As a preferred example of the present application, a texture layer 403 is provided on the side of the transparent substrate layer 401 away from the pattern layer 402. The texture layer 403 is transparently attached to the transparent substrate layer 401 or the texture layer 403 is integrally formed with the transparent substrate layer 401. The design of the texture layer aims to give the decorative back panel a unique visual effect and tactile experience while maintaining its transparency without affecting the color gradient display of the pattern layer. When light penetrates the transparent substrate layer and shines on the texture layer, the fine structure of the texture will scatter or refract the light, producing a unique visual effect. The diversity and plasticity of the texture layer provide users with a wealth of personalized choices. Whether it is a delicate matte texture, an exquisite ice flower texture or a unique geometric pattern, it can complement the color gradient pattern layer to create a unique visual effect and tactile experience.

[0053] This design adds a sense of layering and visual appeal to the decorative back panel, making the entire design more three-dimensional and vivid, ensuring that the color gradient of the pattern layer can be perfectly presented, and further enhancing the user experience.

[0054] The present utility model also discloses a refrigerator, including a box body assembly 1 and a door body assembly 2, a storage cavity 3 is formed on the box body assembly 1, and an opening is formed on the front side of the storage cavity 3, the door body assembly 2 is arranged on the box body assembly 1 and can open or close the front opening of the storage cavity 3, and a refrigerator interior decorative panel as described in the above embodiment is arranged at the rear panel away from the opening in the storage cavity 3.

[0055] The present application discloses a refrigerator with the above-mentioned innovatively designed refrigerator interior decorative panel, which significantly enhances the visual appeal and aesthetics of the refrigerator interior. The combination of the pattern layer and the color gradient, as well as the addition of a transparent texture layer, brings users a richer and more diverse visual enjoyment. It not only meets the practical needs of the refrigerator as a household appliance, but also gives it the function of artistic decoration, thereby enhancing the overall value and market competitiveness of the product.

[0056] As a preferred example of the present application, a plurality of rail supports 5 are provided on the left and right side walls of the storage cavity 3. The rail supports 5 are used to support a shelf 6. When the shelf 6 slides along the rail supports 5 from the opening side of the storage cavity 3 to the inner back panel side, it can abut against and limit the decorative back panel 4. As a specific example of the present application, a plurality of shelf panels 6 are provided from top to bottom in the storage cavity 3, and rail supports 5 are provided on both sides of each shelf panel 6. The shelf panels 6 are arranged perpendicular to the decorative back panel 4, and the plurality of shelf panels 6 are arranged parallel to each other.

[0057] By introducing the track support 5 and the sliding shelf 6, this design makes the use of the internal space of the refrigerator more flexible and efficient. The user can freely adjust the position of the shelf 6 according to the size and shape of the stored items to meet different storage needs; at the same time, the shelf 6 can firmly abut the decorative back panel 4 when sliding into place, which not only ensures the stable placement of the items, but also avoids potential damage of the shelf 6 to the decorative back panel 4, improves the convenience of installation and replacement of the decorative back panel 4 and the stability of placement, maintains the beauty and overall sense of the interior of the refrigerator, and enhances the user experience of the refrigerator.

[0058] As a preferred example of the present application, the shelf 6 is made of acrylic or glass. Compared to the existing shelf 6, the shelf 6 of the present application eliminates the decorative strips provided on the outer ends of the shelf 6, allowing the outer cross-section of the shelf 6 to be exposed and displayed. Combined with the embellishment of the decorative back panel 4, the shelf 6 and the decorative back panel 4 complement each other, not only enhancing the overall aesthetics of the refrigerator interior, but also improving the visual layering, reducing costs, and improving production and assembly efficiency.

[0059] As a preferred example of the present application, a partition 7 is provided near the lower end of the storage cavity 3 , a drawer assembly 8 is provided below the partition 7 , and the lower end of the decorative back panel 4 abuts against the upper surface of the partition 7 .

[0060] This arrangement optimizes the use of the refrigerator's internal space, rationally dividing the storage cavity 3, improving storage efficiency while maintaining a neat interior. The decorative back panel 4 is designed so that its lower end abuts against the partition 7, which not only stabilizes the position of the decorative back panel 4 but also makes the entire internal structure more compact and organized. When the user opens the door assembly 2, the decorative back panel 4 acts as a background, enhancing the visual aesthetics while also ensuring the stable operation of the drawer assembly 8.

[0061] By arranging a partition 7 and a drawer assembly 8 at the lower end of the refrigerator storage cavity 3 and cleverly combining them with the decorative back panel 4, the space utilization is maximized. The arrangement of the partition 7 not only provides a stable support platform, but also enables the decorative back panel 4 to be displayed firmly, thereby enhancing the overall visual effect of the interior of the refrigerator. Through the embellishment of the decorative back panel 4, the aesthetics and grade of the product are improved, bringing a more pleasant user experience to users.

[0062] As a preferred example of the present application, the decorative back panel 4 is fixed to the back panel of the storage cavity 3 by magnetism or gluing on the side surface close to the storage cavity 3 .

[0063] This setting further improves the convenience and stability of installing the decorative back panel 4 in the storage cavity 3 inside the refrigerator. The installation is convenient and simple. It is easy to install and replace the decorative back panel 4, which provides convenience for the personalized decoration of the internal space of the refrigerator, improves the quality of home life, and enhances the comfort and visual enjoyment of use.

[0064] As a preferred example of this application, the ratio of the projected area of the decorative back panel 4 on the back panel of the storage cavity 3 to the area of the back panel of the storage cavity 3 above the partition 7 is 0.6 to 0.96. This configuration ensures that the decorative back panel can effectively embellish and beautify the interior space of the refrigerator, avoiding the monotony caused by a too small decorative back panel area and preventing the visual oppression and cramped feeling caused by an excessively large area. This improves the overall aesthetics of the refrigerator interior without sacrificing the practicality of the storage space, and enhances the user's comfortable and pleasant visual experience when using the refrigerator. As a specific example of this application, the left-right dimension of the decorative back panel 4 is width H, the up-down dimension of the decorative back panel 4 is length L, and the front-to-back dimension of the decorative back panel 4 is thickness T, where the ratio of H to L ranges from 0.45 to 2.2, and T≤5mm. In this example of this application, the thickness of the transparent substrate layer 401 is T1, and the thickness of the protective layer 404 is T2, with T2≤T1. The design fully considers the balance between aesthetics and practicality. It not only conforms to visual aesthetics, but also ensures the applicability of the decorative back panel on refrigerator bodies of different sizes and shapes, providing users with a refrigerator experience that is both beautiful and practical.

[0065] As a preferred example of the present application, the door assembly 2 for covering the storage cavity 3 on the box assembly 1 is a single-door structure or a double-door structure. By adopting a single-door or double-door structure, it not only meets the use requirements of refrigerators of different capacities, but also provides a convenient operating experience.
