[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a panel, door assembly and electrical components. Background Technology

[0002] In related technologies, the panels of appliances such as refrigerators usually have the aesthetic attribute of displaying patterns, as well as the functional attribute of attaching decorative items such as refrigerator magnets. However, existing panels are still in a state of choosing between visual effects and functional expansion, and have poor compatibility between aesthetics and practicality. Utility Model Content

[0024] In the existing technology, the panels of electrical appliances are mainly divided into two categories: one is ordinary panels with metal or plastic as the base material. Although basic decoration can be achieved through surface treatment, they generally have the problems of heavy texture and insufficient gloss, making it difficult to present a transparent and delicate effect like glass, which does not match the simple and exquisite style of modern home furnishings; the other is glass panels, which have high light transmittance and strong gloss, and can meet the aesthetic requirements. However, glass itself is not magnetic and cannot directly attract items such as refrigerator magnets, which limits the user's ability to personalize decorations and record information.

[0025] This utility model proposes a panel 100.

[0026] Please see Figure 1 In one embodiment of this utility model, the panel 100 includes a decorative layer 1, a magnetic layer 2, and a substrate layer 3. The decorative layer 1 has an outer layer 11 made of transparent material. The magnetic layer 2 is disposed on the side of the decorative layer 1 away from the outer layer 11, and the substrate layer 3 is disposed on the side of the magnetic layer 2 away from the decorative layer 1. This arrangement allows the substrate layer 3 to provide support for the decorative layer 1 and the magnetic layer 2. The transparent structure of the outer layer 11 has high light transmittance, giving the panel 100 a transparent and delicate visual effect similar to glass. Furthermore, the magnetic layer 2 is disposed between the substrate layer 3 and the decorative layer 1, allowing decorative items or functional objects made of magnetic or steel materials to be attracted to the surface of the outer layer 11 away from the magnetic layer 2. This solves the problem that the decorative layer 1 itself is not magnetic and cannot directly attract objects. This allows the panel 100 to combine aesthetics and functional expandability. The panel 100 has a high-end glass-like texture that can blend into modern home environments, while also possessing magnetic attraction to meet personalized usage needs.

[0027] It should be noted that the transparent outer layer 11 can be made of glass or a glass-like material. Glass materials include, but are not limited to, soda-lime glass (ordinary flat glass), borosilicate glass, aluminosilicate glass, quartz glass, and lead crystal glass. Glass-like materials include plastics, resins, and new composite materials. Plastics include, but are not limited to, acrylic, polycarbonate, and polyethylene; resins include, but are not limited to, epoxy resin and artificial crystal; and new composite materials include, but are not limited to, acrylic composite stone. The outer layer 11 made of the above materials has the texture and transparency of glass, and the panel 100 can enhance its aesthetics through its high light transmittance and strong gloss. Furthermore, the decorative layer 1 can also enhance its visual effect through printed patterns, etc., without specific limitations here.

[0028] Furthermore, the magnetic layer 2 can be made of magnets, magnetic paint, etc., to give the panel 100 a magnetic function; no specific limitations are imposed here. The substrate layer 3 serves a supporting function, and its material can be made of plastic, steel, etc.; again, no specific limitations are imposed, and it can be selected according to actual needs. The panel 100 proposed in this solution can be applied to home appliances and other fields. This solution uses refrigerators as the main application scenario for illustrative purposes. Applying the panel 100 to a refrigerator gives the refrigerator a glass-like appearance, while also allowing for the magnetic attraction of items such as refrigerator magnets, magnetic whiteboards, small storage boxes, and memo clips, making the refrigerator panel 100 both aesthetically pleasing and practical.

[0029] In addition, the decorative layer 1, the magnetic layer 2 and the substrate layer 3 can be bonded together by adhesive, or by hot melt adhesive vacuum lamination, integral molding and other processes, and no specific limitation is made here.

[0030] In one embodiment, the appearance layer 11 includes a transparent glass-like layer 111 made of a non-glass material. It should be noted that, considering multiple dimensions such as cost, safety, weight, process, and performance, glass is brittle and fragile, inconvenient to process and transport, and expensive. Glass-like materials can achieve a visual effect close to or even surpassing that of glass at a lower cost and in a safer manner, while overcoming many inherent disadvantages of glass. Therefore, using a non-glass transparent glass-like layer 111 for the appearance layer 11 can not only have the texture of glass but also facilitate large-scale production and cost control.

[0031] In one embodiment, the transparent glass-like layer 111 includes at least one of an acrylic layer, a polycarbonate layer, a polystyrene layer, and a polyethylene layer. It is understood that the transparent glass-like layer 111 can be a single-layer structure, and its material can be acrylic (PMMA), polycarbonate (PC), polystyrene (PS), or polyethylene (PE). Acrylic, polycarbonate, and polystyrene have high transparency, while polyethylene is typically a semi-transparent structure. The outer layer 11 can be set to a transparent or semi-transparent structure depending on the different materials used to imitate different styles of glass texture. Of course, in some other embodiments of this utility model, the transparent glass-like layer 111 can also be made of other materials, which are not specifically limited here; or, the transparent glass-like layer 111 can also be a multi-layer structure composed of any combination of the above materials, which is also not specifically limited here.

[0032] In one embodiment, the light transmittance of the transparent glass-like layer 111 is not less than 90%. It is understood that the high light transmittance of the transparent glass-like layer 111 makes the panel 100 appear clear and transparent. It can display the true colors and details of the underlying pattern (such as stone texture or brushed metal printing layer) without reservation. Light loss is minimal as it passes through the transparent glass-like layer 111, reaches the pattern layer 13, and is reflected back. This makes the colors of the pattern more vibrant and saturated, and the textures clearer and more realistic, avoiding color distortion caused by yellowing or fogging of the material.

[0033] In one embodiment, the transparent glass-like layer 111 is made of one of acrylic (PMMA), polycarbonate (PC), polystyrene (PS), and polyethylene (PE), and its light transmittance is not less than 90%.

[0034] In one embodiment, the decorative layer 1 further includes an impact-resistant layer 12, which is disposed between the transparent imitation glass layer 111 and the magnetic layer 2. It should be noted that during the foaming process of the refrigerator door, the substrate layer 3 and the magnetic layer 2 of the panel 100 are subjected to compression. Since the magnetic layer 2 typically has low strength, to prevent damage to the magnetic layer 2 during the foaming process, the impact-resistant layer 12 is made of a tough material and is primarily responsible for absorbing and dispersing impact energy, preventing the panel 100 from cracking or perforating, thus ensuring safety.

[0035] In one embodiment, the impact-resistant layer 12 includes at least one of a polycarbonate layer, a thermoplastic polyurethane layer, and a polyamide layer. The polycarbonate (PC), thermoplastic polyurethane (TPU), and polyamide (PA / nylon) materials used in the impact-resistant layer 12 all possess excellent toughness and can effectively absorb impact energy. For example, if the transparent glass-like layer 111 is made of acrylic while the impact-resistant layer 12 is made of polycarbonate, when subjected to a strong impact, the outer transparent glass-like layer 111 (acrylic PMMA) may break, but the inner impact-resistant layer 12 (polycarbonate PC) can absorb most of the impact energy due to its extremely high toughness, preventing the panel 100 from cracking or perforating, thus ensuring safety.

[0036] In one embodiment, the transparent glass-like layer 111 and the impact-resistant layer 12 are integrally formed. It should be noted that during the production process of the panel 100, the impact-resistant layer 12 and the transparent glass-like layer 111 can be co-extruded into a high-hardness glass-like semi-finished product, which is then used to bond with the magnetic layer 2 and the substrate layer 3. It is understood that the structure formed by co-extrusion gives the panel 100 both the scratch resistance of acrylic (PMMA) and the impact resistance of polycarbonate (PC), exceeding the performance of a single material. Furthermore, the integral forming process simplifies to a one-step continuous molding process, greatly shortening the production cycle and improving production efficiency.

[0037] In one embodiment, the decorative layer 1 further includes a pattern layer 13, which is disposed between the transparent imitation glass layer 111 and the impact-resistant layer 12. It is understood that the pattern layer 13 is disposed between the transparent imitation glass layer 111 and the impact-resistant layer 12 so that the pattern layer 13 can be displayed through the transparent imitation glass layer 111. The impact-resistant layer 12 can be made transparent or opaque, allowing for diverse material choices. The pattern layer 13 can be produced using processes such as screen printing and inkjet printing to achieve the desired design effects.

[0038] In one embodiment, the pattern layer 13 is disposed between the impact-resistant layer 12 and the magnetic layer 2, and the impact-resistant layer 12 is configured as a transparent structure. It is understood that after the impact-resistant layer 12 and the transparent glass-like layer 111 are co-extruded into a high-hardness glass-like semi-finished product, the pattern layer 13 is then processed to the side of the impact-resistant layer 12 away from the transparent glass-like layer 111. To ensure the display effect of the pattern layer 13, the impact-resistant layer 12 also needs to be configured as a transparent structure so that the overall light transmittance of the transparent glass-like layer 111 and the impact-resistant layer 12 meets the design requirements.

[0039] In one embodiment, the outer layer 11 further includes an anti-scratch layer 112, which is disposed on the side of the transparent glass-like layer 111 away from the magnetic layer 2. It should be noted that many highly transparent materials (such as acrylic PMMA and polycarbonate PC) are not very hard, and their surfaces are easily scratched by hard objects such as keys, knives, or even dust in cleaning cloths, resulting in fine scratches. The anti-scratch layer 112 is usually a coating with extremely high hardness (such as silicone or polyurethane coatings), whose Mohs hardness can approach or reach the level of glass (Mohs hardness 5-6), thereby effectively resisting everyday scratches, keeping the surface smooth and mirror-like for a long time, and maintaining the glass texture and visual effect of the panel 100.

[0040] In one embodiment, the scratch-resistant layer 112 is a UV layer. It should be noted that the UV layer is formed by spraying a liquid, UV-sensitive coating onto the substrate surface and then immediately irradiating it with UV light of a specific wavelength, causing it to rapidly transform from a liquid to a hard, solid coating within seconds. The UV layer can achieve a very high crosslinking density through adjustments to its chemical formulation, resulting in a coating with high surface hardness and excellent scratch resistance. Furthermore, the curing time is measured in seconds, compared to the several minutes to hours that traditional paints or coatings may take to dry. Using a UV layer can significantly shorten production cycles and increase production line speed.

[0041] In one embodiment, the panel 100 further includes a first adhesive layer 4, through which the decorative layer 1 is connected to the magnetic layer 2; and / or, the panel 100 includes a second adhesive layer 5, through which the magnetic layer 2 is connected to the substrate layer 3. It should be noted that in this embodiment, an adhesive is used to bond the decorative layer 1, the magnetic layer 2, and the substrate layer 3 together. The material of the first adhesive layer 4 and / or the second adhesive layer 5 can be PUR glue. Alternatively, the first adhesive layer 4 and / or the second adhesive layer 5 can also use epoxy resin glue, acrylic glue (AB glue), etc. No specific limitation is made here; the choice can be made according to actual needs.

[0042] In one embodiment, the magnetic layer 2 is configured as a flexible magnetic cloth layer. It should be noted that, in order to adapt to different panel 100 shapes, the magnetic layer 2 is configured as a flexible magnetic cloth layer that can conform to the shape of the substrate layer 3, and the magnetic cloth layer can deform with the panel 100 during the foaming process without being damaged, so that the panel 100 as a whole has a certain degree of toughness and maintains the stability of the magnetic attraction function.

[0043] In one embodiment, the substrate layer 3 includes at least one of a glass plate, a steel plate, and a plastic plate. It should be noted that during the manufacturing of the panel 100, the substrate layer 3 needs to be processed to a specific external size. After the transparent imitation glass layer 111 and the impact-resistant layer 12 are co-extruded, the decorative layer 1 and the magnetic layer 2 are then bonded together using PUR adhesive. The substrate layer 3 needs to ensure flatness and hardness, and play a pressure-resistant role during foaming. When using steel plate for the substrate layer 3, SPC (cold-rolled carbon steel plate) can be selected, as it has a smooth and flat surface, high strength, and is easy to process. The material of the substrate layer 3 can be adapted according to actual needs and is not specifically limited here.
