Description

Technical Field

[0001] This utility model relates to the field of home appliances, specifically to a door and a refrigerator having the same. Background Technology

[0002] With increasing competition in the home appliance industry, personalized door products are constantly emerging, incorporating features such as illuminated areas. The door itself has a complex multi-layered structure, requiring the light guide plate to be centrally positioned. However, the light guide plate's distance from the door's edge contributes to a bulky appearance, which needs improvement. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a door body that visually creates a narrow edge effect on one side of the light guide plate, reducing the feeling of bulkiness.

[0004] This utility model also aims to provide a refrigerator having the above-mentioned door.

[0005] A door body according to an embodiment of the present utility model includes: a frame with an opening; an interface panel located at the opening, at least a portion of which constitutes a viewing window; a light guide plate located within the frame, with its front facing the viewing window, and its outer peripheral surface including opposing light-guiding first and second sides; and a light-emitting module located within the frame and on the back of the interface panel, the light-emitting module having a light-emitting end facing the light-guiding first side; wherein the frame includes: a first side plate and a first protruding rib, the light-guiding second side of the light guide plate facing the first side plate, the first protruding rib connecting the first side plate and adhered to the interface panel; the light-guiding second side is an inclined surface extending toward the first side plate in a direction away from the interface panel, and the connecting angle between the light-guiding second side and the back of the light guide plate is located on the side of the first protruding rib away from the interface panel.

[0006] According to the embodiments of this utility model, the door body can form a large luminous area by setting a light guide plate and a light-emitting module. The light-emitting module does not need to be too large to reduce the space occupied. The light-emitting module can avoid the viewing window, preventing the light-emitting module from being too bright and causing uneven light effects such as bright spots or bright stripes at the viewing window. It also helps to make the door body thinner and lighter. When the light-emitting module is aligned with the side of the light guide plate, it helps to fill the entire light guide plate with light. The shape and position of the second side of the light guide plate prevent the bright edge from being seen from the front of the door body after the light-emitting module is lit. Moreover, when the user observes the door body from the front, within a certain viewing angle range, the edge of the luminous area seen by the user is closer to the outer edge of the door body, thereby visually reducing the heaviness of the door body's edge.

[0007] In some embodiments, the angle between the second side of the light guide and the back surface of the light guide plate is 45 degrees, and the second side of the light guide is perpendicular to the back surface of the light guide plate.

[0008] In some embodiments, the side of the first rib facing the light guide plate is formed as an inclined surface extending toward the first side plate in a direction away from the interface panel.

[0009] Specifically, the side of the first convex rib facing the light guide plate forms a first gap with the second side of the light guide plate to allow adhesive to overflow.

[0010] In some embodiments, a first overflow groove is provided on the side of the first rib facing the interface panel.

[0011] In some embodiments, the door further includes a sealing cover located within the frame and covering at least a portion of the interface panel, one side of the sealing cover being connected to the first side plate, and the light guide plate and the light-emitting module being located between the sealing cover and the interface panel.

[0012] Specifically, the light-diffusing plate is removed between the light guide plate and the interface panel, and the door body further includes a display module, which is located within the frame and on the back of the light guide plate.

[0013] In some embodiments, the device further includes a thin-film sensing layer disposed on the back of the interface panel and corresponding to the window and the display module, so that the window constitutes a touch screen.

[0014] Specifically, the sealing cover is integrally formed with the first side plate and the first convex rib, and the light guide plate is adhesively bonded to the interface panel.

[0015] The refrigerator according to an embodiment of the present invention includes the door body described in the above embodiment of the present invention.

[0052] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0054] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] The door body 100 according to an embodiment of the present utility model is described below with reference to the accompanying drawings. Figure 1As shown, in this application, the door 100 is the door 100 of a household appliance, which can be the door 100 of a refrigerator 1000 or the door 100 of other household appliances, and the type of household appliance is not limited.

[0056] According to the door body 100 of this utility model embodiment, referring to Figure 2 and Figure 3 It includes: a frame 10, an interface panel 30, and a light-emitting module 80. The interface panel 30 is disposed on the frame 10, and the light-emitting module 80 is disposed inside the frame 10 and located on the back of the interface panel 30, so as to form a light-emitting area on the interface panel 30.

[0057] The frame 10 serves as the border structure of the door 100, providing a stable mounting platform for other components within the door 100. An opening 11 is formed on the frame 10, and the interface panel 30 is located at the opening 11. The edges of the interface panel 30 are supported and protected by the frame 10.

[0058] At least a portion of the interface panel 30 constitutes a window 32. The window 32 serves as the visual interface between the user and the door 100. The remaining portion of the interface panel 30 is not transparent to conceal the internal structure of the door 100. The window 32 allows the functional structures of the door 100 to be displayed within its area, providing a centralized view for easy user access. For example, it allows users to view information displayed by the display module 60 (mentioned below) or operate the touchscreen display. The light-emitting area formed by the light-emitting module 80 on the interface panel 30 can be located within the window 32, thus achieving the lighting effect of the window 32.

[0059] In some schemes of this application, such as Figure 2 and Figure 3 As shown, the door body 100 also includes a sealing cover 20, which is located inside the frame 10 and covers at least a portion of the interface panel 30. The light-emitting module 80 is disposed between the sealing cover 20 and the interface panel 30. In this way, the sealing cover 20 can protect the light-emitting module 80 by cooperating with the interface panel 30, and also facilitates the sealing of the light-emitting module.

[0060] The sealing cover 20 has a light strip compartment 220 that opens towards the interface panel 30, and the light-emitting module 80 is located inside the light strip compartment 220. By forming a light strip compartment 220 on the sealing cover 20 that is adapted to the light-emitting module 80, the light-emitting module 80 can be easily positioned, and assembly and sealing are convenient. In addition, such as Figures 4-6As shown, the door body 100 also includes a spring-loaded assembly 70 disposed on the sealing cover 20, which abuts against the light-emitting module 80 for positioning. The spring-loaded assembly 70 can buffer the vibration of the light-emitting module 80 through its elasticity, and can automatically position the light-emitting module 80 to prevent it from moving around randomly when the door body 100 shakes, causing the light-emitting end to deviate from the design position, thereby reducing the problem of uneven light emission in the light-emitting area on the door body.

[0061] In some embodiments, such as Figure 2 As shown, the light-emitting module 80 is elongated. By making the light-emitting module 80 elongated, the light emitted by the light-emitting module 80 can form a larger light-emitting area, which can significantly change the shape design of the door 100 and form a unique door shape.

[0062] It is understandable that a long light-emitting module 80 is prone to bending and twisting. In this application, the light strip compartment 220 is adapted to the shape of the light-emitting module 80 and is also a long compartment. This can prevent the light-emitting module 80 from bending and reduce its space occupation inside the door 100, improving structural compactness and facilitating the stacking of multiple layers inside the door 100. The spring-loaded component 70 abuts against the light-emitting module 80, and the spring-loaded component 70 applies elastic force to the light-emitting module 80. This not only reduces the squeezing damage to the light-emitting module 80, but also reduces the possibility of the light-emitting module 80 twisting by utilizing the elastic pressure of the contact.

[0063] In some embodiments, such as Figures 2-3 As shown, the door body 100 also includes a light guide plate 50, which is located inside the frame 10. The front of the light guide plate 50 is positioned corresponding to the viewing window 32, and the light-emitting module 80 is located inside the frame 10 and on the side of the light guide plate 50.

[0064] The outer peripheral surface of the light guide plate 50 is annular and connects its front and back sides. The outer peripheral surface of the light guide plate 50 includes a first light-guiding side surface 51. The light-emitting module 80 is a strip extending along the length of the first light-guiding side surface 51. The light-emitting module 80 is positioned towards the first light-guiding side surface 51 to illuminate the entire light guide plate 50 and light up the viewing window 32. Here, the first light-guiding side surface 51 can be the entire outer peripheral surface of the light guide plate 50, or a section or two sections of the outer peripheral surface. The light-emitting module 80 can be located on one or both sides of the light guide plate 50. Because the light-emitting module 80 is strip-shaped, it occupies less space and can occupy little or no space on the back of the light guide plate 50. This allows the light-emitting module 80 to avoid the viewing window 32, preventing the light-emitting module 80 from being too bright and causing uneven light effects such as bright spots or bright stripes at the viewing window 32. It also contributes to the thinner design of the door body 100.

[0065] The light guide plate 50 is essentially an optical material with high light transmittance, which can be an acrylic plate, PMMA plate, or PC plate, etc. When the light-emitting module 80 is powered on and emits light, light enters from the first light-guiding side 51 of the light guide plate 50. Through the scattering effect of the light guide plate 50 itself, the light is conducted and evenly distributed within the light guide plate 50, making the entire light guide plate 50 a light-emitting plate, and the door body 100 forms a light-emitting area at the front viewing window 32.

[0066] Specifically, such as Figure 6 As shown, the outer peripheral surface of the light guide plate 50 includes a first light guide side 51 and a second light guide side 52 facing away from each other, and the light-emitting module 80 has a light-emitting end disposed towards the first light guide side 51.

[0067] Among them, such as Figure 6 As shown, the frame 10 includes a first side plate 121 and a first protruding rib 122. The second light-guiding side surface 52 of the light guide plate 50 is disposed facing the first side plate 121. The first protruding rib 122 is connected to the first side plate 121 and bonded to the interface panel 30. The second light-guiding side surface 52 is an inclined surface extending toward the first side plate 121 in a direction away from the interface panel 30, and the connecting sharp angle between the second light-guiding side surface 52 and the back surface of the light guide plate 50 is located on the side of the first protruding rib 122 away from the interface panel 30.

[0068] By setting the shape and position of the second side 52 of the light guide in this way, after the light-emitting module 80 is lit, it is possible to avoid the appearance of a shiny edge when viewed from the front of the door 100, and it also helps to visually reduce the heaviness of the edge of the door 100.

[0069] Specifically, when light emitted from the light-emitting end of the light-emitting module 80 enters through the first light guide side 51, most of the light propagates directly and illuminates the second light guide side 52. Thus, the light passes through the entire light guide plate 50, thereby illuminating the entire light guide plate 50. In traditional solutions, the second light guide side is perpendicular to the back of the light guide plate. When external light enters through the first light guide side, the light is directed perpendicularly to the second light guide side. A portion of the perpendicularly incident light is reflected perpendicularly back to the first light guide side, and vice versa. This process repeats, resulting in more concentrated light on the second light guide side. Of course, each time light is directed to the second light guide side, some of it is also emitted forward due to the uniform light distribution effect of the light guide plate. However, when observed from the front of the door 100, especially in… Figure 6 When viewed from the right side of the door 100 in the indicated direction, the second side of the light guide will appear as a bright, flashing edge.

[0070] In this application, by forming the second light guide side 52 as an inclined surface, most of the light rays entering from the first light guide side 51 are reflected by the second light guide side 52 to the back of the light guide plate 50, and then reflected forward from the back of the light guide plate 50. This allows the light to be dispersed forward, rather than repeatedly concentrated on the second light guide side 52. Therefore, the degree of glare on the second light guide side can be effectively reduced.

[0071] like Figure 6 As shown, it is understandable that the interface panel 30 needs to be supported on the frame 10. On the side where the second light guide side 52 is located in this application, the frame 10 is formed as a connected first side plate 121 and first protruding rib 122. The first side plate 121 serves as the frame of the door 100 to surround the internal structure, and the first protruding rib 122 is used to connect the interface panel 30, ensuring sufficient support contact area with the interface panel 30 and improving the connection stability of the interface panel 30.

[0072] When a user observes the door 100 from the front, the closer the edge of the light-emitting area is to the outer edge of the door 100, the easier it is to create a sense of lightness. The second side of the light guide 52 is located on the side of the light guide plate 50 adjacent to the edge of the door 100, but it is difficult to make the second side of the light guide 52 visible at the edge of the door 100. When a user observes the door 100 from the front, the position of the edge of the light-emitting area on the door 100 has a direct impact on the user's perception.

[0073] If the user is centered relative to window 32, the edge of the visible area is essentially the edge of window 32. If the user is centered relative to window 32 and looks towards the edge of the visible area, line of sight P1 easily extends beyond the edge of window 32 to the edge of the light guide plate 50. By forming the second side of the light guide 52 into a bevel and placing the connecting sharp angle between the second side of the light guide 52 and the back of the light guide plate 50 on the side of the first convex rib 122 away from the interface panel 30, the visual boundary line P2 of the light guide plate 50 can be seen. Since the visual boundary line P2 is closer to the outer edge of the door 100, the width of the non-light-emitting area on the left side of window 32 is visually reduced, thus reducing the perceived heaviness of the door 100's edge.

[0074] In some embodiments, the angle between the second light guide side 52 and the back surface of the light guide plate 50 is 45 degrees, and the second light guide side 52 is perpendicular to the back surface of the light guide plate 50. This arrangement simplifies manufacturing, prevents the sharp corner between the second light guide side 52 and the back surface of the light guide plate 50 from being too sharp and easily broken, and also prevents the light reflected from the second light guide side 52 to the back surface of the light guide plate 50 from being too concentrated, thus reducing the possibility of strobe.

[0075] Specifically, such as Figure 6As shown, the side of the first convex rib 122 facing the light guide plate 50 is formed as a slope extending toward the first side plate 121 in a direction away from the interface panel 30. This reduces sharp corners and minimizes impact damage. Furthermore, it helps the sloped second light guide side 52 to extend further behind the first convex rib 122, making the visual boundary line P2 at the second light guide side 52 closer to the edge of the door 100.

[0076] Optionally, the side of the first convex rib 122 facing the light guide plate 50 is arranged parallel to the second side of the light guide plate 52.

[0077] Specifically, the side of the first rib 122 facing the light guide plate 50 forms a first gap 541 with the second side of the light guide plate 52 to allow excess adhesive to overflow. In other words, the second side of the light guide plate 52 does not directly abut against the first rib 122, so the first gap 541 between them can catch the excess adhesive from the front, reducing the possibility of excessive adhesive causing bulging.

[0078] like Figure 4 and Figure 6 As shown, the light strip housing 220 extends along the length of the first light guide side 51. The spring-loaded component 70 abuts against the light-emitting module 80 to press the light-emitting module 80 toward the interface panel 30 for positioning. With this configuration, the light-emitting end of the light-emitting module 80 can be positioned relative to the light guide plate 50 by means of the interface panel 30.

[0079] It is understandable that the light guide plate 50 is plate-shaped, and the light-emitting module 80 is strip-shaped and disposed on the side of the light guide plate 50. Therefore, the light-emitting module 80 is a line light source relative to the light guide plate 50. When the light-emitting module 80 is aligned with the side of the light guide plate 50, it helps to distribute light across the entire light guide plate 50. If the light-emitting module 80 is not positioned and is aligned with the rear side of the light guide plate 50, a large amount of light will not enter the light guide plate 50, causing the light guide plate 50 to not light up. Therefore, in this application, the spring-loaded component 70 abuts against the light-emitting module 80, causing the light-emitting module 80 to be pressed against the interface panel 30. The interface panel 30 helps to position the light-emitting module 80, thereby helping to align the light-emitting module 80 with the side of the light guide plate 50 and ensuring the brightness of the light guide plate 50.

[0080] Specifically, there are multiple spring-loaded components 70, which are distributed along the length of the light-emitting module 80. This allows the light-emitting module 80 to be positioned along its entire length, facilitating alignment of the light-emitting module 80 with the light guide plate 50. More specifically, the multiple spring-loaded components 70 are arranged at intervals along the length of the light-emitting module 80, which saves on the number of spring-loaded components 70 and reduces the number of holes required for assembly, thus facilitating sealing.

[0081] Understandably, as a long strip, the light-emitting module 80 is commonly subjected to bending and torsional loads. The longer the light-emitting module 80, the more uncontrollable these two types of loads become. By setting multiple spring-loaded components 70 distributed along the length of the light-emitting module 80, the light-emitting module 80 can be controlled at multiple points. This constrains the bending and torsional behavior of the light-emitting module 80 under load, facilitating overall positioning of the light-emitting module 80 and preventing uneven light emission due to insufficient localized light reception on the light guide plate 50.

[0082] Preferably, the center of the light-emitting end of the light-emitting module 80 is aligned with the mid-thickness plane of the light guide plate 50. That is, the vertical distance from the center of the light-emitting end of the light-emitting module 80 to the front surface of the light guide plate 50 is equal to the vertical distance from the center of the light-emitting end of the light-emitting module 80 to the back surface of the light guide plate 50. This allows more light emitted from the light-emitting end of the light-emitting module 80 to penetrate into the interior of the light guide plate 50. Especially when the light guide plate 50 is relatively wide, the portion of the outer circumference of the light guide plate 50 opposite to the first light-guiding side 51 becomes the second light-guiding side 52. After the torsion amplitude of the light-emitting module 80 is controlled, some of the light emitted by the light-emitting module 80 can directly hit the second light-guiding side 52. This allows the light to cover the entire area of ​​the light guide plate 50, making the light guide plate 50 approach a uniformly bright plate, thereby ensuring uniform brightness in the light-emitting area of ​​the door 100.

[0083] In some embodiments, such as Figures 2-3 As shown, the door 100 also includes a display module 60, which is located within the frame 10 and behind the light guide plate 50. That is, the door 100 has a front facing outwards and a back facing inwards towards the interior of the household appliance. Correspondingly, the front of the interface panel 30 faces outwards, and its back faces the light guide plate 50. The front of the light guide plate 50 faces the interface panel 30, and its back faces the display module 60. The front of the display module 60 faces the light guide plate 50 and displays information on the front. The interface panel 30, the light guide plate 50, and the display module 60 are stacked sequentially along the thickness direction of the door 100.

[0084] When the display module 60 is set, there is no light-diffusing plate between the light guide plate 50 and the interface panel 30. When the display module 60 displays, the information is presented on the window 32, presenting a visual effect that integrates the light-emitting and display functions of the door 100 into one, rather than separating the light-emitting area and the display area.

[0085] When the light-emitting module 80 is not powered on and the display module 60 is also turned off, the light guide plate 50 darkens to form the background of the window 32. The darkened light guide plate 50 can block the back structure. The blocking effect of the darkened light guide plate 50 makes the window 32 an opaque area, thus forming a seamless, opaque panel on the interface panel 30 in the area of ​​the window 32 and the rest of the area.

[0086] It's worth noting that in some traditional door designs, a light-diffusing plate is placed between the light guide plate and the interface panel. When light strikes the light-diffusing plate, the scattering particles or microstructures of the plate cause diffuse reflection, refraction, or diffraction, resulting in randomization of the light's propagation direction and its even distribution across different angles. By scattering, the light-diffusing plate can "mix" light from different areas, reducing brightness gradients.

[0087] In this application, since the display module 60 is located on the back of the light guide plate 50, in order to improve the clarity of the displayed information on the window 32, it is proposed to eliminate the light uniform plate to avoid the display information being blurry or distorted, so that the light-emitting function and display function on the door 100 are integrated into one and do not affect the implementation effect of the function.

[0088] Furthermore, eliminating the light-diffusing plate reduces its obstruction of light, minimizing light loss and increasing light transmittance. When the light guide plate 50 emits light, the viewing window 32 is brighter and clearer, and the luminous area displays a crystal-clear effect. Moreover, reducing the light-diffusing plate simplifies the structure of the door 100, thereby reducing manufacturing costs and assembly complexity. It also helps to reduce weight, facilitating maintenance and transportation.

[0089] exist Figure 7 In the specific embodiment shown, by appropriately setting the color of the back structure of the light guide plate 50, when both the light-emitting module 80 and the display module 60 are off, the display module 60, light guide plate 50, etc., become light shields for the viewing window 32, and the front of the interface panel 30 presents a unified effect. When the light-emitting module 80 is powered on, the light guide plate 50 becomes a surface light source, making the viewing window 32 an emitting area. Furthermore, when the display module 60 is powered on, the display module 60 displays information at the viewing window 32, and the display information is located in the emitting area.

[0090] In some embodiments, such as Figure 7 As shown, the window 32 is an elongated area adjacent to the frame 10, and the length of the light guide plate 50 is at least two-thirds of the length of the door 100. In some designs, the overall length of the window 32 reaches 1064 mm and the width reaches 65 mm, and it can emit light and display light along its entire length, with the window 32 almost occupying the entire length of the door 100. In this way, the front of the door 100 can present a whole luminous area, overlapping the display area presented by the display module 60, resulting in a novel and beautiful door appearance. This large, elongated luminous area is an important design feature that distinguishes the door 100 of this application from existing known door designs.

[0091] In some embodiments of this utility model, the interface panel 30 is a transparent panel in the viewing window 32, while the rest is a non-transparent panel. When the light guide plate 50 emits light, the light is emitted through the viewing window 32, while the rest is blocked. The setting of the viewing window 32 is as follows: Figure 2As shown, this can be achieved using various techniques known in the prior art. For example, the interface panel 30 can be a single piece of material, with transparent material used at the viewing window 32 and non-transparent material used in the remaining areas. Alternatively, the entire interface panel 32 can be fabricated as a single piece using a main transparent plate 31 to improve overall flatness and internal stress uniformity. A light-shielding layer 34 can then be placed on the back of the main transparent plate 31, with the portion without the light-shielding layer 34 forming the viewing window 32. The light-shielding layer 34 can be an ink printing layer, etc.

[0092] In some specific embodiments, such as Figure 8 As shown, the interface panel 30 also includes a main transparent panel 31 and a light-shielding layer 34 disposed on the back of the main transparent panel 31, the light-shielding layer 34 being disposed away from the viewing window 32. The main transparent panel 31 makes the front of the door 100 appear transparent, and the light-shielding layer 34 makes the part of the interface panel 30 other than the viewing window 32 opaque.

[0093] like Figure 8 As shown, a portion of the light-shielding layer 34 is a first light-shielding thickness layer 341, and the remainder is a second light-shielding thickness layer 342. The thickness of the first light-shielding thickness layer 341 is greater than the thickness of the second light-shielding thickness layer 342, and the vertical projection of the light-emitting module 80 on the interface panel 30 is located within the first light-shielding thickness layer 341.

[0094] Understandably, the light-emitting module 80, as a light source, emits high-intensity light. By making the light-shielding layer 34 on the front side thicker, light can be effectively blocked from passing through the non-viewing window area, avoiding visual interference or uneven brightness. The thicker first light-shielding layer 341 can better absorb and block these strong lights, preventing them from directly penetrating the interface panel 30 or reflecting onto the surface of other components, thereby ensuring the clarity and brightness uniformity of the viewing window 32 area.

[0095] In contrast, the second light-shielding thickness layer 342 is applied to other areas of the door body 100. These areas also require a certain amount of light-shielding treatment to maintain the overall aesthetics and consistency. However, since their requirements for light control are relatively low, a thinner thickness layer can meet the needs.

[0096] In some specific embodiments, such as Figure 9 As shown, the door 100 also includes a thin-film sensing layer 36, which is disposed on the back of the interface panel 30 and corresponding to the window 32 and the display module 60, so that the window 32 constitutes a touch screen, that is, a capacitive touch screen. This enables the door 100 to have an interactive experience that integrates lighting, display and touch control.

[0097] Specifically, the main transparent plate 31 is located in front of the thin-film sensing layer 36. Its main function is to protect the screen and optimize the surface texture, capable of withstanding a certain degree of impact and friction, and preventing damage to sensitive components inside the screen. The thin-film sensing layer 36 is the signal function layer of the capacitive screen, typically made of FILM film material, used to transmit touch signals. When a finger touches the window 32, this layer senses the change in capacitance and transmits the signal to the controller, thereby realizing the touch function. Furthermore, there is an optical adhesive layer between the main transparent plate 31 and the thin-film sensing layer 36 to tightly bond them together, forming a seamless connection, reducing light reflection and refraction, and improving the screen's display effect.

[0098] In some specific embodiments, such as Figure 4 As shown, the frame 10 includes: a first side frame plate 12, a second side frame plate 13, a first sealing plate 14, and a second sealing plate 15. The second side frame plate 13 is disposed opposite to the first side frame plate 12, and the first sealing plate 14 connects the first side frame plate 12 and the second side frame plate 13. The second sealing plate 15 is disposed opposite to the first sealing plate 14 and connects the first side frame plate 12 and the second side frame plate 13. The first side frame plate 12, the second side frame plate 13, the first sealing plate 14, and the second sealing plate 15 together form the frame 10, and an opening 11 is formed on the front of the frame 10. That is to say, the frame 10 is generally rectangular, and the first side frame plate 12, the second side frame plate 13, the first sealing plate 14, and the second sealing plate 15 are the four sides of the rectangle. This can form a simple door 100 shape, with a simple structure and easy assembly.

[0099] like Figure 4 As shown, the door 100 also includes a back panel 91, which is disposed opposite to the interface panel 30 and connected to the back of the frame 10. The back panel 91 is used to enclose the foaming space V2. In household appliances, the back panel 91 is the surface of the door 100 facing the cold chamber.

[0100] In some embodiments, such as Figure 8 As shown, the light guide plate 50 is bonded to the back of the interface panel 30 by the adhesive layer 38. In this way, the thickness of the gap between the light guide plate 50 and the interface panel 30 can be controlled by the adhesive layer, so as to avoid the door body 100 from deforming under stress after long-term use, resulting in uneven gap between the light guide plate 50 and the interface panel 30, thereby reducing the problem of uneven brightness and shadow in the light-emitting area caused by uneven gap.

[0101] Specifically, such as Figure 8As shown, when the back of the main transparent plate 31 is coated with light-shielding layers 34 of different thicknesses, the adhesive layer 38 includes a first adhesive layer 381 and a second adhesive layer 382. The first adhesive layer 381 is coated on the corresponding area of ​​the window 32, and the second adhesive layer 382 is coated on the back of the second light-shielding layer 342. The thickness of the first adhesive layer 381 is greater than the thickness of the second adhesive layer 382, ​​so that the gap between the light guide plate 50 in the area of ​​the window 32 and the interface panel 30 is filled by the first adhesive layer 381, and the gap between the outer area of ​​the window 32 and the interface panel 30 is filled by the second adhesive layer 382. This avoids the formation of air bubbles that affect the uniformity and clarity of light transmission in the window 32, and reduces spots and shadows in the light-emitting area.

[0102] Furthermore, the adhesive layer 38 also includes a third adhesive layer 383, which is coated on the back side of the first light-shielding layer 341. The thickness of the third adhesive layer 383 is less than the thickness of the second adhesive layer 382. In this way, the third adhesive layer 383 can adhere the light-emitting module 80 and balance the thickness difference between the first light-shielding layer 341 and the second light-shielding layer 342, thus avoiding uneven light emission in the final light-emitting area caused by the light guide plate 50 being tilted relative to the main transparent plate 31.

[0103] Specifically, such as Figure 3 As shown, a reflective film 53 is provided on the back of the light guide plate 50. It can be understood that the main function of the light guide plate 50 is to scatter side-incident light (such as LED light sources) into the viewing window 32 area through surface microstructures (such as dots and prisms). However, some light may deviate in direction due to refraction or scattering, exiting through the back of the light guide plate 50, forming "light leakage." The reflective film 53, made of a high-reflectivity material (typically >95%), reflects the leaked light back into the interior of the light guide plate 50, preventing light waste and thus improving overall brightness. The reflective film 53 can also, through its diffuse reflection properties, redirect stray light from the back of the light guide plate 50 back into the effective light path, reducing local hot spots or dark areas in the light distribution and helping to improve the uniformity of the displayed image.

[0104] In some embodiments, such as Figure 5 and Figure 6 As shown, the two sides of the sealing cover 20 form a sealing space V1 and a foaming space V2, respectively. Specifically, the sealing cover 20 and the interface panel 30 form the sealing space V1, and the light guide plate 50 and the light-emitting module 80 are located within the sealing space V1. The frame 10, the sealing cover 20, and another part of the interface panel 30 enclose the foaming space V2. The foaming material is filled in the foaming space V2 and then fills the entire foaming space V2 after foaming, so that the door 100 has a heat preservation function.

[0105] In some specific embodiments, such as Figure 4 and Figure 6As shown, the sealing cover 20 includes a first cover plate 21, a second cover plate 22, and a third cover plate 23 arranged sequentially along its width direction. The first cover plate 21, the second cover plate 22, and the third cover plate 23 are all connected to the frame 10 at both ends in the length direction.

[0106] The first cover plate 21 is located on the back of the light guide plate 50, and one side of the first cover plate 21 is connected to the frame 10. The second cover plate 22 is connected to the other side of the first cover plate 21, and the light-emitting module 80 is located between the second cover plate 22 and the interface panel 30. The third cover plate 23 is connected to the side of the second cover plate 22 away from the first cover plate 21, and the third cover plate 23 is connected to the interface panel 30.

[0107] This design divides the sealing cover 20 into at least three sections along its width to accommodate the space requirements of the light guide plate 50 and the light-emitting module 80, reducing gaps and ensuring that the force generated by the foamed material is evenly transmitted to the light guide plate 50 and the light-emitting module 80, preventing uneven stress that could cause component misalignment. Furthermore, the interface panel 30 has a large area and is prone to deformation under stress; therefore, a third cover plate 23 is provided to connect to the interface panel 30, increasing the connection area between the sealing cover 20 and the interface panel 30 and ensuring a tight seal. However, this design is not limited to this; for example, the third cover plate 23 can be omitted, and the second cover plate 22 can be directly connected to the interface panel 30.

[0108] Here, the sealing cover 20 has a large flat structure in the area of ​​the first cover plate 21, used to cover the light guide plate 50. A second cover plate 22 with a groove structure is integrally extruded on one side of the first cover plate 21, serving as the installation space for the light-emitting module 80. The integral molding improves assembly accuracy. A third cover plate 23 is integrally extruded on one side of the second cover plate 22, which can serve as a wide-edge adhesive application surface, solving the problem of unstable adhesion between the cover plate and the interface panel 30 caused by only having an adhesive application surface on the frame 10.

[0109] Specifically, such as Figure 4 and Figure 10 As shown, the third cover plate 23 and the frame 10 are glued to the interface panel 30. Since the third cover plate 23 is connected to the frame 10 at both ends in the length direction, the third cover plate 23 and the frame 10 form a stable figure 8 shape, making the partitioned bonding of the interface panel 30 more reliable.

[0110] In some specific embodiments, the third cover plate 23 and a portion of the frame 10 form a first adhesive surface s1 on the side facing the interface panel 30, and the first adhesive surface s1 is connected to the interface panel 30 through an annular first adhesive layer 901.

[0111] Another part of the frame 10 forms a second adhesive surface s2 on the side facing the interface panel 30. The second adhesive surface s2 is a C-shape arranged around the light guide plate 50. The interface panel 30 is connected through the second adhesive layer 902 of the C-shape. The two ends of the second adhesive layer 902 are connected to the first adhesive layer 901.

[0112] In other words, the frame 10 itself has an annular adhesive surface facing the interface panel 30, and the adhesive surface on the frame 10 is set along the edge of the interface panel 30, or in other words, along the edge of the opening 11. The third cover plate 23 has a strip-shaped adhesive surface that extends along its length direction and faces the interface panel 30.

[0113] The annular adhesive surface on frame 10 is divided into two parts by the third cover plate 23, both of which are C-shaped. One part surrounds the light guide plate 50, while the other part does not. The C-shaped adhesive surface that does not surround the light guide plate 50 combines with the adhesive surface on the third cover plate 23 to form the first annular adhesive surface s1, while the C-shaped adhesive surface that surrounds the light guide plate 50 forms the second adhesive surface s2.

[0114] Understandably, because the first adhesive surface s1 lacks a sealing cover 20, foaming liquid can easily flow into the gaps during foaming in the foaming space V2. The second adhesive surface s2, however, has a sealing cover 20, reducing the sealing difficulty. Therefore, this application divides the adhesive surface into a ring-shaped first adhesive surface s1 and a C-shaped second adhesive layer 902, allowing for specific sealing parameters to be set according to the sealing difficulty. During sealing, the first adhesive layer 901 is first applied to the first adhesive surface s1, ensuring that the first adhesive layer 901 is closed-loop and sufficiently wide, thus guaranteeing a complete seal between the first adhesive surface s1 (which has a high sealing difficulty) and the interface panel 30. Then, a C-shaped second adhesive layer 902 is set on the second adhesive surface s2 to ensure that both ends of the second adhesive layer 902 can be connected to the first adhesive layer 901. In this way, the second adhesive layer 902 can be sealed by the first adhesive layer 901 to form a closed loop. This ensures that the second adhesive surface s2, which has a relatively low sealing difficulty, can be completely sealed with the interface panel 30, and that the first adhesive layer 901 and the second adhesive layer 902 are not disconnected, and the connection can be sealed.

[0115] This structure of the sealing cover 20 not only solves the installation scheme of the light-emitting module 80 through innovative design, but also solves the sealing scheme proposed based on the distribution of the sealing space V1 and the foaming space V2. Furthermore, the setting of the third cover plate 23 solves the problem that the first adhesive layer 901 and the second adhesive layer 902 are difficult to connect.

[0116] Specifically, the width of the first adhesive application surface s1 is greater than the width of the second adhesive application surface s2, so that the first adhesive layer 901 can be set to be wider than the second adhesive layer 902. Optionally, the first adhesive application surface s1 is rectangular, which is the main adhesive fixing plane. The second adhesive application surface s2 is C-shaped, which is the auxiliary adhesive sealing plane.

[0117] Here, the surface of the third cover plate 23 facing the interface panel 30 is part of the first adhesive surface s1. It has a large width, and its large flat surface and material rigidity can prevent local points of foam deformation from squeezing the light guide plate 50, thus solving the problem of uneven light emission caused by local points of foaming material squeezing the light emission area.

[0118] Optionally, the first adhesive application surface s1 and the second adhesive application surface s2 are located on the same plane. This makes it easier to control the uniformity of the adhesive layer thickness and helps maintain the continuity of the adhesive layer at the junction of the first adhesive application surface s1 and the second adhesive application surface s2. By constructing the two as a plane, the auxiliary adhesive sealant and the main adhesive sealant are fixed on the same plane, ensuring a seamless seal and solving the problem of moisture and dust ingress.

[0119] In some embodiments, such as Figure 2 and Figure 4 , Figure 6 As shown, the side of the first cover plate 21 away from the second cover plate 22 is connected to the first side plate 121. A first protruding rib 122 is connected to the first side plate 121. The first protruding ribs 122 are spaced apart between the interface panel 30 and the first cover plate 21. The surface of the first protruding rib 122 facing the interface panel 30 constitutes part of the second adhesive surface s2. Here, the first side plate 121 is the plate of the frame 10 used to enclose the sealed space V1 and the foaming space V2. Of course, the plate of the frame 10 used to enclose the sealed space V1 and the foaming space V2 may have other side plates. The first side plate 121 is the side plate connected to the long side of the first cover plate 21. By providing the first protruding rib 122 on the side of the first side plate 121 facing the interface panel 30, the frame 10 can support the interface panel 30, provide sufficient adhesive surface to bond the interface panel 30, and maintain the uniformity and stability of the distance between the interface panel 30 and the light guide plate 50.

[0120] Among them, such as Figure 6 As shown, the first rib 122 is also provided with a first overflow groove 123 on the side facing the interface panel 30. In this way, when the second adhesive layer 902 between the second adhesive surface s2 and the interface panel 30 is not applied evenly, the excess adhesive can overflow into the first overflow groove 123, avoiding the problem of excess adhesive overflowing from the connection between the frame 10 and the interface panel 30 and causing extrusion deformation.

[0121] Optionally, the first convex rib 122 is spaced apart from the first cover plate 21, and a second overflow groove 124 is formed between the first convex rib 122, the first side plate 121, the first cover plate 21 and the second side surface 52 of the light guide. In this way, excess adhesive can overflow into the second overflow groove 124, avoiding excess adhesive from overflowing from the connection between the frame 10 and the interface panel 30 and causing extrusion deformation problems.

[0122] In some specific embodiments, a light strip reservoir 220 is formed on the second cover plate 22, and both ends of the light strip reservoir 220 extend to the frame 10, such as... Figure 2 In the middle, the two ends of the light strip compartment 220 extend to the first sealing plate 14 and the second sealing plate 15.

[0123] Specifically, the spring-loaded assembly 70 is detachably mounted on the sealing cover 20. It is understood that the light-emitting module 80 can be inserted from the end of the light strip compartment 220 or from the side of the light strip compartment 220 facing the interface panel 30 during assembly. Since the light-emitting module 80 is relatively long, excessive obstruction during assembly can easily cause jamming or improper positioning. The detachable spring-loaded assembly 70 allows for adjustment during assembly, thereby reducing assembly difficulty, improving positioning accuracy, and ensuring cost-effectiveness and reliability. For example, in some designs, the light-emitting module 80 can be installed into the light strip compartment 220 first, and then the spring-loaded assembly 70 can be installed, thus directly using the spring-loaded assembly 70 to press the light-emitting module 80 into the accurate position.

[0124] Specifically, such as Figure 4 and Figure 6 As shown, the spring-loaded assembly 70 includes a spring-loaded block 71, located on the side of the light-emitting module 80 away from the interface panel 30, for pressing the spring-loaded block 71 against the interface panel 30. The spring-loaded assembly 70 uses the spring-loaded block 71 to press the light-emitting module 80. The arrangement of the spring-loaded block 71 increases the contact area with the light-emitting module 80, reducing stress on the contact surface. This properly disperses the elastic force, preventing deformation of the light-emitting module 80.

[0125] Optionally, the spring-loaded block 71 itself has a certain elastic deformation capability, for example, the spring-loaded block 71 is a rubber block, etc.

[0126] In some specific embodiments, such as Figure 6 As shown, the spring-loaded assembly 70 also includes a spring-loaded spring 72, which is connected to the spring-loaded block 71. This allows the spring-loaded spring 72 to obtain a large elastic force, maintain the persistence of the elastic compression, and ensure that the compression and positioning effect of the spring-loaded assembly 70 on the light-emitting module 80 is effective for a long time.

[0127] In some embodiments, such as Figure 6 As shown, the sealing cover 20 has a first mounting hole 221 that connects to the light strip compartment 220. The spring-loaded assembly 70 includes a spring-loaded seat 73, which is mounted on the sealing cover 20 and has a spring-loaded groove 730 facing the first mounting hole 221. The spring-loaded block 71 is partially located within the spring-loaded groove 730 and partially passes through the first mounting hole 221 and abuts against the light-emitting module 80.

[0128] Therefore, the spring-loaded assembly 70 can be positioned and assembled through the first assembly hole 221 during assembly, especially when there are multiple spring-loaded assemblies 70, allowing adjacent spring-loaded assemblies 70 to maintain an appropriate distance. Furthermore, a portion of the spring-loaded block 71 is inserted into the light strip housing 220 through the first assembly hole 221. A large space needs to be left inside the light strip housing 220 for the spring-loaded assembly 70, and the light strip housing 220 can be adapted to the light-emitting module 80 for easy assembly. The spring-loaded assembly 70 is assembled outside the light strip housing 220, and then the spring-loaded seat 73 is used to cover the first assembly hole 221 to seal the first assembly hole 221, preventing foaming liquid from flowing into the light strip housing 220 from the first assembly hole 221.

[0129] The spring 72 is located within the spring compression groove 730 and is connected to the spring compression block 71, which is used to press the spring compression block 71 against the interface panel 30. In this way, the position of the spring compression spring 72 is restricted by the spring compression seat 73, which also guides the direction of the spring force of the spring compression spring 72.

[0130] Specifically, such as Figure 6 , Figure 11 and Figure 12 As shown, the second cover plate 22 in the sealing cover 20 includes: two opposite cover plate side walls 222, and a cover plate bottom wall 223 connected between the two cover plate side walls 222. A light strip compartment 220 is formed between the two cover plate side walls 222 and the cover plate bottom wall 223. A through first assembly hole 221 is provided on the cover plate bottom wall 223.

[0131] The spring-loaded seat 73 includes a seat body 731, located on the side of the bottom wall 223 of the cover plate opposite to the lamp strip compartment 220. A spring-loaded groove 730 is formed on the seat body 731, which covers the first mounting hole 221. The spring-loaded seat 73 also includes seat arms 732 connected to both sides of the seat body 731, with each arm 732 respectively engaged with one of the two side walls 222 of the cover plate. By securing the spring-loaded seat 73 with the two arms 732, the spring-loaded seat 73 can maintain a tight seal against the bottom wall 223 of the cover plate, reducing the likelihood of leakage from the gap between them.

[0132] Optionally, on the second cover plate 22, the side wall 222 and the bottom wall 223 of the cover plate are connected by an arc transition. On the spring-loaded seat 73, the seat body 731 and the seat arm 732 are connected by an arc transition. The two arcs are equal and the arc surfaces are in contact. This use of arc surface contact further reduces the chance of leakage and plays a role in preventing the foaming material from overflowing.

[0133] In some specific embodiments, such as Figure 11 and Figure 12As shown, one of the cover plate sidewalls 222 and the seat arm 732 is provided with a first wall groove 7321, and the other is provided with a first retaining rib 2221. The first retaining rib 2221 is engaged in the first wall groove 7321. In this way, the seat arm 732 has a certain deformation elasticity, which makes it easy to insert the first retaining rib 2221 into the first wall groove 7321. This creates the effect of the seat arm 732 holding the two cover plate sidewalls 222 tightly, reducing the risk of the spring-loaded seat 73 falling off.

[0134] Furthermore, the cover plate sidewall 222 is provided through the length of the sealing cover 20, and the first wall groove 7321 or the first retaining rib 2221 provided on the cover plate sidewall 222 is provided through the length of the sealing cover 20.

[0135] Specifically, there are multiple spring-loaded components 70, and the bottom wall 223 of the cover plate is provided with multiple spaced-apart first mounting holes 221. When the side wall 222 of the cover plate is provided with first retaining ribs 2221, the first retaining ribs 2221 corresponding to two adjacent first mounting holes 221 are located on the same straight line. When the side wall 222 of the cover plate is provided with first wall grooves 7321, the first wall grooves 7321 corresponding to two adjacent first mounting holes 221 are located on the same straight line. In this way, during assembly, the spring-loaded seat 73 can be installed from the end of the sealing cover 20 onto the second cover plate 22, allowing the first retaining ribs 2221 to be inserted into the first wall grooves 7321 and slide along the length of the second cover plate 22 until they reach the position of the corresponding first mounting hole 221.

[0136] Optionally, such as Figure 11 and Figure 12 As shown, the first wall groove 7321 and the first retaining rib 2221 extend along the length of the light-emitting module 80. The bottom wall of the first wall groove 7321 is provided with a second retaining rib 7322, and the first retaining rib 2221 is provided with a second wall groove (not shown in the figure). The second retaining rib 7322 is engaged in the second wall groove.

[0137] by Figure 12 For example, both arm 732 have a first wall groove 7321, and both cover sidewalls 222 have a corresponding first retaining rib 2221. At this time, a second retaining rib 7322 is formed on the bottom wall of the first wall groove 7321 of one arm 732, and a second wall groove is formed on the corresponding first retaining rib 2221 on the cover sidewall 222. The second wall groove corresponds to the first mounting hole 221. Thus, when the second retaining rib 7322 is not engaged in the second wall groove, the spring-loaded seat 73 can slide along the length of the second cover 22 to adjust its position, following the extension direction of the first wall groove 7321 and the first retaining rib 2221. Once the second retaining rib 7322 is engaged in the second wall groove, the spring-loaded seat 73 is positioned, thereby limiting the position of the spring-loaded assembly 70 to prevent slippage and affecting the seal.

[0138] Optionally, the first retaining rib 2221 is provided with a third retaining groove 2223 corresponding to the first mounting hole 221, and the seat arm 732 is inserted into the third retaining groove 2223. That is to say, the third retaining groove 2223 restricts the entire seat arm 732, which is more conducive to preventing the spring seat 73 from shaking and dislodging from the position of the first mounting hole 221.

[0139] In some embodiments, such as Figure 11 As shown, the surface of the light-emitting module 80 includes a first positioning surface f1, and the inner wall surface of the light strip housing 220 includes a second positioning surface f2. Both the first positioning surface f1 and the second positioning surface f2 are planar and have surface contact. When the first positioning surface f1 and the second positioning surface f2 are planar and in contact, their contact area is large, which can reduce the probability of the light-emitting module 80 twisting.

[0140] Optionally, the two opposite surfaces of the light-emitting module 80 are both first positioning surfaces f1, and the two opposite surfaces of the inner wall of the light strip container 220 are both second positioning surfaces f2. In this way, both sides are limited.

[0141] Specifically, such as Figure 11 As shown, the surface of the light-emitting module 80 facing the interface panel 30 is the third positioning surface f3. The third positioning surface f3 is planar and contacts the surface of the interface panel 30. It can be understood that this configuration makes the surface of the interface panel 30 in contact with the light-emitting module 80 planar, facilitating manufacturing. The surface contact between the interface panel 30 and the third positioning surface f3 of the light-emitting module 80 allows for better contact when pressed by the spring-loaded component 70. Compared to other surface types, the planar nature of the third positioning surface f3 of the interface panel 30 and the light-emitting module 80 allows for automatic positioning by the spring-loaded component 70 when the light-emitting module 80 shifts.

[0142] In some specific embodiments, such as Figure 12 As shown, the surface of the spring-loaded block 71 facing the interface panel 30 includes a fourth positioning surface f4. The fourth positioning surface f4 is elongated and perpendicular to the length direction of the light-emitting module 80. The fourth positioning surface f4 contacts and engages with the surface of the light-emitting module 80. This arrangement ensures that the length of the contact surface between the spring-loaded block 71 and the light-emitting module 80 is maximized in the width direction of the light-emitting module 80, so that the light-emitting module 80 is spring-loaded and limited in the entire width direction, making the light-emitting module 80 less prone to twisting.

[0143] With this configuration, the fourth positioning surface f4 has a smaller dimension in the length direction of the light-emitting module 80, which makes it easier for the spring-loaded block 71 to be assembled into the light strip compartment 220 through the first assembly hole 221.

[0144] Specifically, such as Figure 11As shown, the spring-loaded block 71 includes a spring-loaded head section 711, a perforated section 712, and a spring-loaded tail section 713. The perforated section 712 connects the spring-loaded head section 711 and the spring-loaded tail section 713. The perforated section 712 is located within the first mounting hole 221, the spring-loaded head section 711 is located within the light strip housing 220, and the spring-loaded tail section 713 is located within the spring-loaded groove 730. This division into three sections, with each section matching in shape and position, limits the extension height of the spring-loaded block 71 within the light strip housing 220.

[0145] Specifically, the cross-section of the spring-loaded tail section 713 is larger than the cross-sectional area of ​​the first mounting hole 221. The spring-loaded tail section 713 cannot extend into the first mounting hole 221 to avoid the spring-loaded block 71 squeezing the light-emitting module 80 excessively, causing the light-emitting module 80 to be squeezed, deformed, or arched.

[0146] Furthermore, the spring-loaded head section 711 is triangular in shape, and the fourth positioning surface f4 is located at the tip of the spring-loaded head section 711. This makes the connection between the spring-loaded head section 711 and the perforated section 712 wider, thus avoiding misalignment caused by bumps during assembly.

[0147] Specifically, the first mounting hole 221 is a non-circular hole, and the through-hole section 712 has the same shape as the first mounting hole 221. For example, the first mounting hole 221 is a square hole, and the through-hole section 712 is a square block. This prevents the spring block 71 from rotating relative to the first mounting hole 221, which helps to keep the fourth positioning surface f4 perpendicular to the length direction of the light-emitting module 80.

[0148] In some embodiments, such as Figure 4 As shown, the light strip container 220 is provided to extend through at least one end of the sealing cover 20 along its length. Figure 13 As shown, at least one end of the frame 10 corresponding to the light strip compartment 220 has a mounting port 102. Thus, a long strip-shaped light-emitting module 80 can be inserted into the light strip compartment 220 from the mounting port 102 at one end of the frame 10, with the insertion direction as shown... Figure 13 As indicated by the thick arrow. After the entire light-emitting module 80 is inserted, the wiring harness of the light-emitting module 80 is led out from the mounting port 102. This assembly method allows the light-emitting module 80 to be inserted into the light strip compartment 220 after the sealing cover 20 is assembled to the interface panel 30, facilitating a sealed connection between the sealing cover 20 and the interface panel 30, preventing dust and impurities from entering the sealed space V1, and reducing the impact of impurities on the lighting effect.

[0149] Specifically, the first sealing plate 14 is provided with an installation port 102, which is used to ensure a tight seal, such as Figure 10 As shown, the door body 100 also includes a cover 16 connected to the first sealing plate 14, thereby covering the mounting opening 102.

[0150] In some specific embodiments, such as Figure 13As shown, the inner side of the mounting port 102 adjacent to the interface panel 30 is a mounting surface u1. The frame 10 has an inner stop surface u2 facing the light-emitting module 80 and connected to the mounting surface u1, which limits the end of the light-emitting module 80. That is, although the light-emitting module 80 needs to be inserted into the light strip compartment 220 at a slight tilt due to the obstruction of the mounting surface u1 when inserted into the mounting port 102, the inner stop surface u2 can be used to stop the end of the light-emitting module 80 after insertion. In this way, the light-emitting module 80 is less likely to pop out during the assembly process, and it is easier to position the light-emitting module 80 using the spring-loaded component 70 afterwards.

[0151] Specifically, the frame 10 has an installation port 102 at one end corresponding to the light strip compartment 220, while the other end of the light strip compartment 220 has no port. For example... Figure 14 As shown, the other end of the light strip compartment 220 is directly sealed by the second sealing plate 15, and the light strip compartment 220 is closed here.

[0152] Specifically, the first side frame panel 12 includes a first side panel 121, the second side frame panel 13 includes a second side panel 131, the first sealing panel 14 includes a third side panel 141, and the second sealing panel 15 includes a fourth side panel 151. The first side panel 121, the third side panel 141, the second side panel 131, and the fourth side panel 151 extend generally in a direction perpendicular to the interface panel 30 and are connected end to end to form a rectangular frame. The first side panel 121, the third side panel 141, the second side panel 131, and the fourth side panel 151 are the outermost side panels of the door body 100, and then form an encapsulated whole through the front interface panel 30 and the back panel 91.

[0153] The first side frame plate 12 further includes a first protruding rib 122 connecting the first side plate 121, the second side frame plate 13 includes a second protruding rib 132 connecting the second side plate 131, the first sealing plate 14 includes a third protruding rib 142 connecting the third side plate 141, and the second sealing plate 15 includes a fourth protruding rib 152 connecting the fourth side plate 151.

[0154] The sealing cover 20 is connected between the first sealing plate 14 and the second sealing plate 15, and the third cover plate 23 is spliced ​​with the third protruding rib 142 and the fourth protruding rib 152 to form a continuous adhesive application surface. That is, the second protruding rib 132, part of the third protruding rib 142, the third cover plate 23, and part of the fourth protruding rib 152 can form a rectangular first adhesive application surface s1. The first protruding rib 122, part of the third protruding rib 142, and part of the fourth protruding rib 152 can form a C-shaped second adhesive application surface s2.

[0155] Specifically, the first side plate 121 and the first protruding rib 122 are integrally molded parts, forming an integral first side frame plate 12. The second side plate 131 and the second protruding rib 132 are integrally molded parts, forming an integral second side frame plate 13. The third side plate 141 and the third protruding rib 142 are integrally molded parts, forming an integral first sealing plate 14. The fourth side plate 151 and the fourth protruding rib 152 are integrally molded parts, forming an integral second sealing plate 15. In this way, the four sides of the frame 10 are processed separately, which facilitates assembly and the construction of various adhesive surfaces and assembly surfaces.

[0156] Specifically, such as Figure 4 and Figure 5 As shown, the sealing cover 20 is integrally formed on the first side frame plate 12. This integrated design solves the sealing problem at the connection between the sealing cover 20 and the first side frame plate 12, making it difficult for dust, impurities, and moisture to enter the transparent light-emitting area. Furthermore, the back of the sealing cover 20 is a foaming space V2, and the front is a sealing space V1. By integrally forming it with the first side frame plate 12, the problem of uneven light emission caused by the foaming and compression of the light-emitting area can be solved. In addition, after this integral forming, the light-emitting module 80 and the light guide plate 50 are positioned by the sealing cover 20, and the sealing cover 20 is fixed in position by being integrally formed with the first side frame plate 12. Therefore, the relative positions of the light-emitting module 80 and the light guide plate 50 are highly controllable, solving the problem of uneven light emission caused by the influence of installation accuracy.

[0157] Furthermore, the sealing cover 20 is integrally formed with the first side plate 121 and the first protruding rib 122. The first side frame plate 12 and the sealing cover 20 are integrally formed extruded parts, and even further, both are aluminum alloy parts.

[0158] In some specific embodiments, such as Figure 2 As shown, the first cover plate 21 has a pre-embedded opening 211. The display module 60 includes a pre-embedded box 62 and a display 66. The opening 620 of the pre-embedded box 62 faces the light guide plate 50 and fits into the pre-embedded opening 211. The display 66 is located inside the pre-embedded box 62 and has a display section 661 facing the light guide plate 50. With this configuration, the first cover plate 21 can still be flat overall, and only the thickness space required for the light guide plate 50 needs to be left on the front side, without excessive extra space. At the same time, the first cover plate 21 cooperates with the pre-embedded box 62 to cover the back of the light guide plate 50 with the display 66, achieving a good sealing effect. The first cover plate 21 is plate-shaped, and with its own structural strength, it can effectively support and avoid uneven distances from the light guide plate 50 caused by the deformation of the foamed material during foaming and extrusion, thus reducing the problem of uneven light emission.

[0159] Specifically, such as Figure 2As shown, the opening 620 of the embedded box 62 faces the light guide plate 50. The display module 60 also includes a display bracket 64, which is disposed inside the embedded box 62. The display 66 is disposed on the display bracket 64, and the display 66 has a display part 661 facing the light guide plate 50. The display part 661 is the part of the display 66 that emits light, such as LCD, OLED, MiniLED, etc.

[0160] The embedded box 62 is used to fix the display bracket 64, ensuring the stability and accurate positioning of the display bracket 64. The display bracket 64 further provides the necessary support for the monitor 66, preventing the monitor 66 from wobbling within the embedded box 62.

[0161] According to the refrigerator 1000 of this utility model embodiment, referring to... Figure 15 The door body 100, as described in the above embodiments, will not be described in detail here.

[0162] It is worth noting that the type of refrigerator 1000 here is not limited, and can be a side-by-side refrigerator, multi-door refrigerator, French door refrigerator, built-in refrigerator, upright freezer, or display cabinet, etc. Through the door 100 of this embodiment of the invention, a completely new appearance can be achieved, realizing a visual effect that integrates the light-emitting and display functions of the door 100 into one, ensuring that the displayed content is clearly visible, thereby enhancing the optical precision and overall quality of the refrigerator 1000's appearance. Other components of the refrigerator 1000 according to this embodiment of the invention, such as the evaporator and condenser, as well as their operation, are known to those skilled in the art and will not be described in detail here.
