Description

Technical Field

[0001] This invention pertains to the field of refrigerator technology, specifically relating to a refrigerator and its door lighting device. Background Technology

[0002] Conventional refrigerators typically have front-facing lights for easy access to items. However, in existing built-in refrigerators, the hinge structure and door thickness limit the ability to achieve a continuous horizontal light across the front. Most refrigerators have protruding vertical light strips on the front of the door. These protruding light strips are not aesthetically pleasing, are easily bumped and damaged, and take up a lot of space. Furthermore, the vertical lighting area is narrow, creating blind spots and resulting in poor lighting effects and intensity, thus failing to achieve a continuous horizontal light across the front. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a refrigerator and its door lighting device.

[0004] The present invention adopts the following technical solution.

[0005] The first aspect of this utility model discloses a refrigerator door lighting device, comprising: a door light guide strip, a door light strip, and a lower end cover of the door, characterized in that:

[0006] The door light guide strip has a stepped structure on the front and a sloping structure on the back, forming a structure that is wider at the top and narrower at the bottom. It is horizontally embedded into the refrigerator door through the stepped structure and is connected to the lower end cover of the door through the sloping structure. The door light strip is set on the upper end of the door light guide strip, corresponding to the position inside the refrigerator door.

[0007] Preferably, the light guide strip of the door body includes: a light guide strip light surface and a light guide strip light extension surface. The upper end of the light guide strip light surface is provided with a light guide strip light extension surface. There is a gap at the front connection between the light guide strip light surface and the light guide strip light extension surface to form a stepped structure, and a continuous inclined structure is formed on the back.

[0008] Preferably, the refrigerator door has a door panel on the front, and the door panel is snapped into a stepped structure so that the door light guide strip is horizontally embedded inside the refrigerator door, and the door light strip is close to the back of the door panel.

[0009] Preferably, the upper end of the light guide strip of the door body is provided with a protrusion, and the door body light strip is disposed on the upper end surface of the protrusion.

[0010] Preferably, the lower end cover of the door includes: a light guide strip fixing surface and a bottom surface located below it, with a gap between the bottom surface and the front of the light guide strip fixing surface, and the light guide strip of the door is embedded into the lower end cover of the door through the gap and is attached to the light guide strip fixing surface through the inclined structure.

[0011] Preferably, the inclined structure and the surface where the light guide strip is fixed are provided with a textured surface.

[0012] Preferably, the lower end cover of the door is made of an opaque material. The light emitted from the door light strip passes through the door light guide strip in a straight line from top to bottom. The light is reflected by the lower end cover of the door and dispersed into multi-directional light by the textured surface, so that the door light guide strip emits light uniformly as a whole.

[0013] A second aspect of the present invention discloses a refrigerator, including the aforementioned refrigerator door lighting device.

[0014] The beneficial effect of this utility model is that, compared with the prior art,

[0015] This utility model provides a structure that allows the front light of a refrigerator to be horizontally and continuously integrated, resulting in a better product display effect, stronger overall integrity, and a larger and more intense lighting area. Furthermore, the door light guide strip is an embedded light guide, saving space, avoiding bumps and collisions, and improving aesthetics. At the same time, this utility model is a structure where the light is visible but the lamp is not, achieving concealed lighting and enhancing the product's sophistication and perceived value.

[0016] The door light guide strip of this utility model is horizontally embedded into the refrigerator door through a stepped structure. Based on the flat-embedded product, the door light guide strip horizontally runs through the refrigerator door, allowing the light to pass through horizontally, expanding the lighting area and improving the lighting intensity. The door light guide strip is embedded in the refrigerator door and is not easily damaged by bumps, saving space. The door light guide strip not only serves as a light guiding medium but also as a decorative part, improving the aesthetics.

[0017] This utility model uses a stepped structure on the front of the door light guide strip to make the front of the door light guide strip and the front of the door panel nearly flush, saving space and improving the structural compactness and aesthetics. At the same time, by increasing the height of the door light guide strip, space is made up for other internal equipment such as flush-mounted hinges, thus improving applicability.

[0018] Meanwhile, on the one hand, the sloping structure and the protrusion make the door light guide strip a structure that is wider at the top and narrower at the bottom. On the other hand, the door light strip is close to the back of the door panel, so that the light emitted by the door light strip can pass through the entire door light guide strip vertically to the maximum extent, which increases the light intensity and the lighting display effect of the refrigerator door, improves the light utilization rate, and realizes the horizontal overall connection of the front light of the refrigerator door.

[0019] The light emitted from the door light strip of this utility model passes straight through the door light guide strip from top to bottom until the light is reflected by the lower end cover of the door and dispersed into multi-directional light by the concave and convex texture, so that the door light guide strip emits light evenly as a whole, which improves the lighting intensity and light utilization rate, saves energy, and at the same time illuminates the concave and convex texture, improving the decorative effect.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The embodiments described in this application are merely some embodiments of this utility model, not all embodiments. Based on the spirit of this utility model, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

[0031] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] like Figures 1-9 As shown, this utility model discloses a refrigerator door lighting device, including: a door light guide strip 11, a door light strip 13, and a door lower end cover 14. The front of the door light guide strip 11 has a stepped structure 113 and the back has a sloping structure 115, forming a structure that is wider at the top and narrower at the bottom. It is horizontally embedded into the refrigerator door 1 through the stepped structure 113 and is attached to the door lower end cover 14 through the sloping structure 115. The door light strip 13 is set on the upper end of the door light guide strip 11, corresponding to the position inside the refrigerator door 1.

[0033] like Figure 5 As shown, the refrigerator door 1 has a door panel 12 on the front. The door panel 12 is inserted into the stepped structure 113, so that the door light guide strip 11 is horizontally embedded inside the refrigerator door 1. The door light strip 13 is close to the back of the door panel 12. The stepped structure 113 makes the door light guide strip 11 and the front of the door panel 12 nearly flush, saving space and improving the structural compactness and aesthetics.

[0034] like Figure 7 , Figure 8 and Figure 9 As shown, the door light guide strip 11 includes: a light guide strip light surface 111, a light guide strip light extension surface 112, and a protrusion 114. The light guide strip light surface 111 has a light guide strip light extension surface 112 at its upper end. There is a gap between the front of the light guide strip extension surface 112 and the front of the light guide strip light surface 111, so that a stepped structure 113 is formed at the connection between the light guide strip extension surface 112 and the light guide strip light surface 111. The back of the door light guide strip 11 is a continuous inclined structure 115 and a protrusion 114 is provided at its upper end to form a structure that is wider at the top and narrower at the bottom. The door light strip 13 is provided on the upper surface of the protrusion 114.

[0035] The protrusion 114 increases the contact area between the door light strip 13 and the door light guide strip 11, improving the stability of the connection between the door light guide strip 11 and the door light strip 13. The door light guide strip 11 has a structure that is wider at the top and narrower at the bottom, allowing light to penetrate vertically to the maximum extent, thus increasing the lighting intensity. At the same time, the door light strip 13 is close to the back of the door panel 12, further allowing light to penetrate vertically to the maximum extent. Thus, when the door light strip 13 shines downwards, the light can pass through the light guide extension surface 112 of the light guide strip and shine onto the light surface 111 of the light guide strip, realizing the overall horizontal continuity of the front light of the refrigerator door 1, increasing the light intensity and the lighting display effect of the refrigerator door 1.

[0036] Furthermore, the door light strip 13 is located on the back of the door panel 12, achieving concealed light guidance. The door light strip 13 is not visually visible on the front of the refrigerator door 1, enhancing the refrigerator's sophistication, perceived value, and aesthetics.

[0037] like Figure 5 and Figure 6 As shown, the lower end cover 14 of the door body includes: a bottom surface 142 and a light guide strip fixing surface 141. The upper surface of the bottom surface 142 is provided with the light guide strip fixing surface 141. There is a gap between the front of the light guide strip fixing surface 141 and the front of the bottom surface 142. The door body light guide strip 11 is embedded into the lower end cover 14 of the door body through the gap and is attached to the light guide strip fixing surface 141 through the inclined structure 115, which improves the overall structure and aesthetics and saves space. The back of the door body light guide strip 11 is attached to the light guide strip fixing surface 141 and the lower end surface is attached to the bottom surface 142.

[0038] The matching arrangement of the light guide strip fixing surface 141 and the bottom surface 142 allows the door light guide strip 11 to be directly fixed to the lower end cover 14 of the door without the need for fixing components. This increases the contact area between the door light guide strip 11 and the lower end cover 14 of the door, enhances the stability of the connection between the door light guide strip 11 and the lower end cover 14 of the door, and provides sufficient light guiding space for the light without changing the thickness of the refrigerator door 1. It also reserves sufficient installation space for hinges and other internal equipment inside the refrigerator door 1, saving space and improving the structural compactness.

[0039] The light guide strip 11 of the door body is provided with a textured surface 116 on the side that is in contact with the fixing surface 141 of the light guide strip. The lower end cover 14 of the door body is made of opaque material, and the light guide strip 11 of the door body is made of light guiding material. The light emitted from the light strip 13 of the door body passes through the light guide strip 11 of the door body in a straight line from top to bottom. The light is reflected by the lower end cover 14 of the door body and dispersed into multi-directional light by the textured surface 116, so that the light guide strip 11 of the door body emits light evenly as a whole, thereby improving the light utilization rate.

[0040] The working principle of this utility model is as follows: the light emitted downward from the door light strip 13 is transmitted to the light surface 111 of the light guide strip through the light guide extension surface 112 of the light guide strip. The light penetrates vertically through the entire door light guide strip 11 until the light is reflected by the lower end cover 14 of the door and dispersed into multi-directional light by the concave and convex texture 116, so that the door light guide strip 11 emits light evenly as a whole, and the front light of the refrigerator door 1 is fully connected from left to right. The horizontal light will greatly reduce the shadow area and improve the lighting effect and visual openness.

[0041] This utility model also discloses a refrigerator, including the aforementioned refrigerator door lighting device.

[0042] The beneficial effect of this utility model is that, compared with the prior art,

[0043] This utility model provides a structure that allows the front light of a refrigerator to be horizontally and continuously integrated, resulting in a better product display effect, stronger overall integrity, and a larger and more intense lighting area. Furthermore, the door light guide strip is an embedded light guide, saving space, avoiding bumps and collisions, and improving aesthetics. At the same time, this utility model is a structure where the light is visible but the lamp is not, achieving concealed lighting and enhancing the product's sophistication and perceived value.

[0044] The door light guide strip of this utility model is horizontally embedded into the refrigerator door through a stepped structure. Based on the flat-embedded product, the door light guide strip horizontally runs through the refrigerator door, allowing the light to pass through horizontally, expanding the lighting area and improving the lighting intensity. The door light guide strip is embedded in the refrigerator door and is not easily damaged by bumps, saving space. The door light guide strip not only serves as a light guiding medium but also as a decorative part, improving the aesthetics.

[0045] This utility model uses a stepped structure on the front of the door light guide strip to make the front of the door light guide strip and the front of the door panel nearly flush, saving space and improving the structural compactness and aesthetics. At the same time, by increasing the height of the door light guide strip, space is made up for other internal equipment such as flush-mounted hinges, thus improving applicability.

[0046] Meanwhile, on the one hand, the sloping structure and the protrusion make the door light guide strip a structure that is wider at the top and narrower at the bottom. On the other hand, the door light strip is close to the back of the door panel, so that the light emitted by the door light strip can pass through the entire door light guide strip vertically to the maximum extent, which increases the light intensity and the lighting display effect of the refrigerator door, improves the light utilization rate, and realizes the horizontal overall connection of the front light of the refrigerator door.

[0047] The light emitted from the door light strip of this utility model passes straight through the door light guide strip from top to bottom until the light is reflected by the lower end cover of the door and dispersed into multi-directional light by the concave and convex texture, so that the door light guide strip emits light evenly as a whole, which improves the lighting intensity and light utilization rate, saves energy, and at the same time illuminates the concave and convex texture, improving the decorative effect and aesthetics.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model.
