[0026] Existing ambient lighting solutions for refrigerator door handles primarily use strip light panels to achieve their lighting function, emitting direct light. This direct light, due to the obstruction of the door handle structure and the physical characteristics of light propagation, easily creates noticeable shadows around the door handle. These shadows not only disrupt the uniform and soft lighting effect intended by the ambient lighting, reducing visual comfort, but may also affect the user's overall perception of the refrigerator's appearance, failing to meet consumers' pursuit of aesthetically pleasing, high-quality home products.
[0027] Therefore, this application proposes a door structure and a refrigerator, aiming to solve the problem that existing refrigerator door handle ambient lighting solutions easily produce shadows, affecting the lighting effect.
[0028] The following is combined Figures 1 to 3 Describe the door structure of this application.
[0029] The door structure proposed in the first aspect of this application is applied to a refrigeration device. Please refer to [reference needed]. Figure 1 and Figure 2 The door structure includes a door assembly 1 and a light source assembly 2. One end of the door assembly 1 is provided with a door handle (not shown). The light source assembly 2 is located at the end of the door assembly 1 where the door handle is located. The light source assembly 2 can be used as an ambient light for the door handle.
[0030] The door assembly 1 includes a door panel and a door frame surrounding the door panel. End caps 11 are located at opposite ends of the door frame (e.g., upper and lower ends). One end cap has a recessed structure forming a door handle, as can be seen in existing conventional designs. A light source assembly 2 is located on the inner wall of the end cap 11 corresponding to the door handle and is used to illuminate the door handle. The light source assembly 2 includes a lamp panel assembly 21 and a transparent light guide 22. In the height direction of the door assembly 1, the lamp panel assembly 21 is located on the side of the transparent light guide 22 facing the end cap 11.
[0031] The lamp panel assembly 21 includes at least one LED (not shown), which emits light. The transparent light guide 22 includes a light guide plate 221 and a light guide structure 222 corresponding to the LED. One end of the light guide structure 222 couples light onto the light-emitting surface of the LED, and the other end couples light onto the light guide plate 221. The light guide structure 222 is used to conduct the light emitted by the LED to the light guide plate 221.
[0032] The door structure of this utility model embodiment provides a transparent light guide 22 below the light panel assembly 21. The transparent light guide 22 includes a light guide plate 221 extending along the end face of the end cover 11 and a light guide structure 222 connected to the light guide plate 221. By coupling the light at the end of the light guide structure 222 to the light-emitting surface of the lamp beads in the light panel assembly 21, the light emitted by the lamp beads is transmitted to the light guide plate 221 through the light guide structure 222, avoiding direct lighting. Therefore, while meeting the lighting requirements of the door handle, it can avoid the generation of shadows and improve the lighting effect.
[0033] Please refer to Figure 1 and Figure 2 The end cap 11 is provided with a wire hole 111 that extends through the end cap 11 along the height direction of the door assembly 1. The wire hole 111 is used to thread the wire harness connected to the light panel assembly 21. The light panel assembly 21 is located at the position corresponding to the wire hole 111.
[0034] Traditional refrigerator door handle ambient lighting often uses long strip light panels. However, these panels are bulky, requiring a certain thickness in the refrigerator door and a specific handle size. In traditional refrigerator designs, accommodating them necessitates a large amount of space, limiting design flexibility and innovation. Furthermore, the trend towards ultra-thin built-in refrigerators has led to extremely limited door space. Existing long strip light panel lighting solutions, constrained by size, cannot fit the ultra-thin refrigerator door structure; forcing their installation would negatively impact the refrigerator's performance and appearance.
[0035] Compared to the traditional long strip light panel structure, the light panel assembly 21 of this utility model embodiment is smaller in size, can be arranged at the wire hole 111, does not require a large space, and is suitable for ultra-thin door structures.
[0036] Please refer to Figure 2 and Figure 3 The light guide structure 222 is a flexible light guide column, the diameter of which is larger than the diameter of the LED bead, allowing the light emitted by the LED bead to be transmitted to the light guide plate 221 through the flexible light guide column. Specifically, the LED bead is located at the axial position on the end face of the light guide structure 222, which ensures that the light can enter the flexible light guide column evenly, improving the utilization rate of light.
[0037] Among them, the light guide structure 222 adopts a flexible light guide column, which can be adapted to lamp panel assemblies 21 of different specifications, thus improving the applicability of the light source assembly 2.
[0038] In one embodiment, the end face shape of the flexible light guide column used to connect with the LED bead is adapted to the shape of the light-emitting surface of the LED bead. The light-emitting surface of the LED bead is nested inside the flexible light guide column to ensure that light emitted from all directions of the LED bead can enter the flexible light guide column, thereby improving light utilization.
[0039] In one embodiment, the light guide structure 222 and the light guide plate 221 can be integrally formed. The transparent light guide 22 is made of a high light transmittance material (such as acrylic) to ensure that light is effectively transmitted in the light guide structure 222.
[0040] In one embodiment, the lamp panel assembly 21 includes multiple LEDs, and a light guide structure 222 is capable of coupling light to the light-emitting surfaces of the multiple LEDs. The light emitted by the multiple LEDs is transmitted to the light guide plate 221 through the light guide structure 222. Alternatively, the transparent light guide 22 is provided with multiple light guide structures 222, and the light from each of the multiple light guide structures 222 is coupled to the light-emitting surfaces of the multiple LEDs. The light emitted by each LED is transmitted to the light guide plate 221 through the corresponding light guide structure 222.
[0041] It should be noted that the length and diameter of the light guide structure 222 can be adjusted according to requirements, and there are no restrictions here.
[0042] Please refer to Figure 3 The light guide plate 221 has a receiving groove 23 at the position corresponding to the wire hole 111. The lamp panel assembly 21 is housed in the receiving groove 23, which can reduce the occupation of extra space and is beneficial to the design of ultra-thin door structure.
[0043] The lamp panel assembly 21 includes a lamp panel mounting base 212 and a lamp panel 211. The lamp panel 211 is fixed to the transparent light guide 22 by the lamp panel mounting base 212. The lamp panel 211 is located on the side surface of the lamp panel mounting base 212 facing the end cover 11, and the lamp beads are disposed on the lamp panel 211.
[0044] In one embodiment, a light-blocking structure (not shown) is provided around the LED bead. The light-blocking structure is used to block the light emitted by the LED bead from scattering in all directions, so as to ensure that the light is conducted through the light guide structure 222 and avoid the shadows produced by direct light.
[0045] The light-blocking structure can be made of opaque materials, such as metal or non-transparent plastic. The shape and size of the light-blocking structure can be adjusted according to the specific design of the LED and the light guide structure 222, and there are no restrictions here.
[0046] According to a second aspect embodiment of the present application, a refrigerator includes a cabinet and the aforementioned door structure. The cabinet has a storage space, and the door structure is rotatably disposed on the cabinet to open or close the storage space.
[0047] It is understandable that the door structure can be installed on the box body through a rotating mechanism (such as a hinge, pivot, etc.). By rotating the door structure, the storage space can be opened or closed, making it convenient for users to store and retrieve items.
[0048] It should be noted that the refrigerator of this application has all the technical effects of the aforementioned door structure because it includes the door structure described above, and will not be repeated here.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
