[0006] Technical problems to be solved by utility models

[0007] The aforementioned prior art refrigerator light-emitting assemblies are complex in structure, resulting in a cumbersome installation process. Furthermore, the light-emitting assemblies occupy a large space, affecting the thermal insulation performance of the refrigerator door. Furthermore, since the light-emitting assemblies are pre-installed on the door, it is difficult to disassemble and install them when replacing LEDs with different brightness levels.

[0008] Technical means for solving technical problems

[0009] The present invention is completed in view of the above technical problems, and its purpose is to provide a light-emitting component with a simple structure, convenient assembly and disassembly, and soft light emission.

[0010] One embodiment of the present invention provides a light-emitting component, which includes: a light-emitting component, which irradiates light toward the rear side of the light-emitting component; a light guide component, which includes an upper part of the light guide component and a lower part of the light guide component, the light-emitting component is installed on the front side of the upper part of the light guide component, and the front side of the lower part of the light guide component is exposed; and a fixed bracket, which includes an upper part of the fixed bracket and a lower part of the fixed bracket, the upper part of the fixed bracket is located on the rear side of the upper part of the light guide component, and the lower part of the fixed bracket is located on the rear side and the lower side of the lower part of the light guide component, and the light is irradiated backward from the light-emitting component and emitted forward under the guidance of the light guide component.

[0011] In this light-emitting assembly, the light's direction of illumination is opposite to that of the light guide. The light passes through the C-shaped light guide before exiting, resulting in a softer, more luminous light without the grainy effect of direct LED light. The fixed bracket supports the light guide. Furthermore, the light-emitting assembly has few components and a compact structure, taking up little space. When installed on a refrigerator door, this light-emitting assembly minimizes the door's thermal insulation. Furthermore, the light-emitting assembly's simple structure and easy assembly and disassembly facilitate the replacement of LEDs with varying brightness levels.

[0012] In the above-mentioned lighting assembly, optionally, the upper portion of the fixing bracket and the lower portion of the fixing bracket are formed by a light shielding member. According to such a structure, the light emitted from the lighting element is more effectively guided in the light guide element.

[0013] In the above-mentioned light-emitting assembly, the light guide is optionally formed with a welding post, and the light-emitting member is formed with a through hole at a position corresponding to the welding post. The welding post passes through the through hole and is fixed to the light guide member by heat riveting. According to such a structure, the light-emitting member is reliably and firmly fixed to the light guide member.

[0014] In the aforementioned light-emitting assembly, optionally, a rearwardly protruding fixing claw is formed on the rear side of the upper portion of the light guide, and a fixing slot is formed on the upper portion of the fixing bracket at a position corresponding to the fixing claw. The fixing claw engages with the fixing slot to secure the light guide to the fixing bracket. With this structure, the light guide is reliably and securely secured to the fixing bracket.

[0015] In the aforementioned light-emitting assembly, the fixing claws may optionally be formed with an inclined surface that slopes from the upper end toward the lower end, such that the upper end protrudes more than the lower end. With this structure, when the light guide is secured to the fixing bracket from the bottom up, the inclined surface of the fixing claws of the light guide assists the fixing claws in sliding into the fixing slots of the fixing bracket, thereby facilitating installation of the light guide to the fixing bracket.

[0016] In the above-mentioned light-emitting assembly, optionally, a groove recessed upward is formed on the lower side of the lower portion of the light guide, and a protrusion protruding upward is formed on the lower portion of the fixing bracket at a position corresponding to the groove, and the light guide is fixed to the fixing bracket by engaging the groove and the protrusion. According to this structure, the light guide is further reliably and firmly fixed to the fixing bracket.

[0017] In the aforementioned light-emitting assembly, the front-to-back length of the lower portion of the fixing bracket can optionally be shorter than the front-to-back length of the lower portion of the light guide. With this structure, the lower portion of the fixing bracket only partially covers the lower portion of the light guide, leaving a greater front side of the lower portion of the light guide exposed. This allows light to be emitted over a larger area, thereby ensuring the brightness of the light-emitting assembly.

[0018] Another embodiment of the present invention provides a refrigerator, comprising a door mounted on the front side of the refrigerator, wherein a downwardly opening receiving slot is provided on the lower side of the door for receiving the light-emitting assembly. A mounting claw is formed on the wall of the receiving slot near the rear side of the door, and a mounting slot is formed on the upper portion of a fixing bracket at a position corresponding to the mounting claw. The fixing bracket is fixed to the receiving slot by engaging the mounting claw with the mounting slot. In such a refrigerator, the light-emitting assembly is installed from bottom to top into the downwardly opening receiving slot on the refrigerator door, and the fixing bracket is securely and firmly fixed to the receiving slot.

[0019] In the refrigerator described above, the mounting claws may optionally be formed with an inclined surface that slopes from the upper end toward the lower end, such that the protrusion at the upper end is greater than that at the lower end. With this structure, when the fixing bracket is secured to the receiving slot from the bottom up, the inclined surface of the mounting claws of the receiving slot assists the mounting claws in sliding into the mounting slot of the fixing bracket, thereby facilitating installation of the fixing bracket into the receiving slot.

[0020] In the above-mentioned refrigerator, optionally, the height of the front side of the receiving groove near the door body is smaller than the height near the rear side of the door body, and the front side of the lower part of the light guide is exposed at the front side of the receiving groove near the door body. According to such a structure, a portion of the receiving groove is exposed at the front side near the door body, and the light is emitted from the front side of the lower part of the light guide. The emission area of ​​the light is larger, ensuring the brightness of the light-emitting component. By installing the above-mentioned light-emitting component on the door body of the refrigerator, the light passes through the "C"-shaped light guide of the light guide before being emitted, making the emitted light softer and without the graininess of direct light from the LED lamp beads. In addition, the light-emitting component has fewer components, a compact structure, and takes up less space. When such a light-emitting component is installed on the refrigerator door, it has little effect on the thermal insulation performance of the refrigerator door. In addition, since the light-emitting component has a simple structure and is easy to disassemble and assemble, it is convenient to replace LED assemblies of different brightness.

[0033] Figure 1 FIG1 is an exploded perspective view showing a light emitting assembly 10 and a door 100 of a refrigerator 1 according to an embodiment of the present invention. Figure 1As shown, the light-emitting assembly 10 includes a light-emitting part 11, a light guide part 12 and a fixing bracket 13. The door body 100 includes a door glass 101, a door frame 102 and a door liner 103. Here, the side of the door body 100 close to the door glass 101 is defined as the front side of the refrigerator 1, and the side of the door body 100 close to the door liner 103 is defined as the rear side of the refrigerator 1. The door body 100 is installed on the front side of the refrigerator 1. A downwardly opening accommodating groove 1001 is provided on the lower side of the door body 100 for accommodating the light-emitting assembly 10. The light-emitting assembly 10 extends along the bottom surface of the door body 100. Here, the extension direction of the light-emitting assembly 10 is defined as the length direction.

[0034] The light-emitting element 11 is, for example, an LED light bar that illuminates the rear side of the light-emitting assembly 10. To enhance the user experience, the light-emitting element 11 is configured to have an appropriate brightness. The color of the light emitted by the light-emitting element 11 can be customized by the user, enhancing the user's personalized experience. Furthermore, due to its easy assembly and disassembly, LEDs of varying brightness can be replaced.

[0035] The light guide 12 is made of a uniformly light-transmissive material, such as resin. It can be injection molded. It includes welding posts 121. These posts 121 protrude from the front surface of the light guide 12 toward the front of the refrigerator 1. Multiple welding posts 121 can be evenly spaced along the length of the light-emitting assembly 10. The light-emitting element 11 has through-holes 111 formed in locations corresponding to the welding posts 121.

[0036] Figure 2 1 is a perspective view showing a light guide 12 fixed with a light emitting element 11 according to an embodiment of the present invention. Figure 2 As shown, the welding column 121 passes through the through hole 111 and is connected by heat riveting to fix the light emitting element 11 to the light guide 12. According to such a structure, the light emitting element 11 is reliably and firmly fixed to the light guide 12.

[0037] Figure 3 1 is a perspective view showing a fixing bracket 13 to which a light guide 12 is fixed, viewed from the rear side, according to an embodiment of the present invention.

[0038] like Figure 1 and Figure 3 As shown, the fixing bracket 13 is formed with a fixing slot 131 and an installation slot 132. Multiple fixing slots 131 can be evenly spaced along the length of the light-emitting assembly 10. Multiple installation slots 132 can be evenly spaced along the length of the light-emitting assembly 10. The fixing bracket 13 can be injection molded. For aesthetic reasons, the color of the fixing bracket 13 is preferably consistent with the exterior color of the door body 100.

[0039] Figure 4 The diagram is shown when viewed from the direction indicated by the arrow. Figure 3AA line cuts off the cross-sectional view of the light emitting component 10.

[0040] When viewed from the direction indicated by the arrow, that is, along the length direction of the light-emitting component 10, the cross-sectional shape of the light guide 12 is roughly L-shaped. The light guide 12 includes an upper light guide portion 12a and a lower light guide portion 12b. The light-emitting component 11 is mounted on the front side of the upper light guide portion 12a. The front side of the lower light guide portion 12b is exposed. When viewed from the length direction of the light-emitting component 10, the cross-sectional shape of the fixed bracket 13 is roughly L-shaped. The fixed bracket 13 includes an upper fixed bracket portion 13a and a lower fixed bracket portion 13b. The upper fixed bracket portion 13a is located on the rear side of the upper light guide portion 12a. The lower fixed bracket portion 13b is located on the rear side and the lower side of the lower light guide portion 12b. The fixed bracket 13 serves to support the light guide 12. The upper fixed bracket portion 13a and the lower fixed bracket portion 13b are composed of light-shielding components. According to such a structure, the light emitted from the light-emitting component 11 is more effectively guided within the light guide 12. Specifically, the light is emitted backward from the light emitting element 11 and is guided forward by the light guide 12 .

[0041] A rearwardly protruding fixing claw 122 is formed on the rear side of the light guide upper portion 12a. A fixing slot 131 is formed on the fixing bracket upper portion 13a at a position corresponding to the fixing claw 122. The engagement of the fixing claw 122 with the fixing slot 131 secures the light guide 12 to the fixing bracket 13. With this structure, the light guide 12 is securely and firmly fixed to the fixing bracket 13.

[0042] More specifically, the fixing claw 122 has an inclined surface 122a that slopes from the upper end toward the lower end, so that the upper end protrudes more than the lower end. With this structure, when the light guide 12 is secured to the fixing bracket 13 from the bottom up, the inclined surface 122a of the fixing claw 122 of the light guide 12 assists the fixing claw 122 in sliding into the fixing slot 131 of the fixing bracket 13, thereby facilitating the installation of the light guide 12 on the fixing bracket 13.

[0043] Furthermore, an upwardly recessed groove 123 is formed on the underside of the light guide lower portion 12b, and an upwardly projecting protrusion 133 is formed on the fixing bracket lower portion 13b at a position corresponding to the groove 123. The engagement between the groove 123 and the protrusion 133 secures the light guide 12 to the fixing bracket 13. This structure further reliably and securely secures the light guide 12 to the fixing bracket 13.

[0044] Furthermore, the front-to-back length of the fixing bracket lower portion 13b is shorter than the front-to-back length of the light guide lower portion 12b. With this structure, the fixing bracket lower portion 13b only covers a portion of the light guide lower portion 12b, leaving more of the front side of the light guide lower portion 12b exposed. This allows the light to be emitted over a larger area, ensuring the brightness of the light-emitting assembly 10.

[0045] Figure 5 1 is a perspective view showing a door body 100 with a light emitting assembly 10 installed. As can be seen, the light emitting assembly 10 has few exposed side lines and has a good overall fit with the door body 100.

[0046] Figure 6 The diagram is shown when viewed from the direction indicated by the arrow. Figure 5 The BB line is a cross-sectional view of the door body 100 with the light emitting assembly 10 installed. Figure 6 As shown, a downwardly opening receiving groove 1001 is provided on the lower side of the door body 100. The wall of the receiving groove 1001 close to the rear side of the door body 100 is formed with a mounting claw 1002 whose wall surface protrudes toward the front side of the refrigerator 1. A plurality of mounting claws 1002 can be evenly spaced and distributed in the longitudinal direction of the light-emitting component 10. A mounting slot 132 is formed on the upper portion 13a of the fixing bracket at a position corresponding to the mounting claw 1002. The fixing bracket 13 is fixed to the receiving groove 1001 by engaging the mounting claw 1002 with the mounting slot 132. In such a refrigerator 1, the light-emitting component 10 is installed from bottom to top into the downwardly opening receiving groove 1001 on the door body 100 of the refrigerator 1, and the fixing bracket 13 is reliably and firmly fixed to the receiving groove 1001.

[0047] More specifically, the mounting claw 1002 is formed with an inclined surface 1002a that slopes from the upper end toward the lower end, such that the upper end protrudes more than the lower end. With this structure, when the fixing bracket 13 is secured to the receiving slot 1001 from the bottom up, the inclined surface 1002a of the mounting claw 1002 in the receiving slot 1001 assists the mounting claw 1002 in sliding into the mounting slot 132 of the fixing bracket 13, thereby facilitating the installation of the fixing bracket 13 in the receiving slot 1001.

[0048] Furthermore, the height of the receiving groove 1001 near the front side of the door body 100 is smaller than the height near the rear side of the door body, and the front side of the lower portion 12b of the light guide is exposed near the front side of the receiving groove 1001 near the door body. With this structure, a portion of the receiving groove 1001 is exposed near the front side of the door body 100, and light is emitted from the front side of the lower portion 12b of the light guide, which has a larger emission area, thereby ensuring the brightness of the light-emitting assembly 10.

[0049] By installing the aforementioned light-emitting assembly 10 on the door 100 of the refrigerator 1, the light passes through the C-shaped light guide 12 before being emitted, resulting in a softer light beam without the grainy effect of direct LED light. Furthermore, the light-emitting assembly 10 has few components and a compact structure, occupying little space. When installed on the refrigerator door, this light-emitting assembly 10 has minimal impact on the door's thermal insulation performance. Furthermore, due to its simple structure and easy assembly and disassembly, the light-emitting assembly 10 facilitates the replacement of LEDs with different brightness levels.

[0050] In this embodiment, if Figure 1 and Figure 3 As shown, the fixing slot 131 and the installation slot 132 can be staggered and arranged at different positions on the upper part 13a of the fixing bracket. However, this is not limiting. In a modified example of this embodiment, adaptive adjustments can be made. For example, the fixing slot 131 and the installation slot 132 can also be set to the same slot. In this case, the installation claw 1002 can be adjusted so that the protrusion of the lower end of the installation claw 1002' is greater than the protrusion of the upper end, and an inclined surface 1002a' is formed that tilts from the lower end to the upper end, while the fixing claw 122 remains unchanged. That is, the installation claw 1002' is staggered with the fixing claw 122. At this time, the inclined surface 122a of the fixing claw 122 and the inclined surface 1002a' of the installation claw 1002' face each other and fit together. Alternatively, the fixing claw 122 can be adjusted so that the lower end of the fixing claw 122' protrudes more than the upper end, forming an inclined surface 122a' that tilts from the lower end to the upper end, while the mounting claw 1002 remains unchanged. Alternatively, the mounting claw 1002 and the fixing claw 122' can be offset. In this case, the inclined surface 122a' of the fixing claw 122' and the inclined surface 1002a of the mounting claw 1002 face and mate with each other. As a result, the fixing slot 131 and the mounting slot 132 serve as a common slot. This reduces the number of slots in the upper portion 13a of the fixing bracket, saving the slotting process of the fixing bracket 13.

[0051] In this embodiment, the light-emitting assembly 10 is mounted on the door 100 of the refrigerator 1. However, this is not limiting. In a variation of this embodiment, the light-emitting assembly 10 can also be mounted on the edge of the air duct or the edge of a partition inside the refrigerator 1. Light-emitting assembly 10 mounted on the edge of the air duct or the edge of a partition inside the refrigerator 1 can also achieve the aforementioned advantages of simple structure, easy assembly and disassembly, and soft light.
