Description

Technical Field

[0001] This utility model belongs to the technical field of LED lights for freezer doors, and more specifically, it relates to an embedded LED light on a rounded corner door. Background Technology

[0002] In practical applications of freezer equipment, embedded LED lights are a key component for improving ease of use, and their performance directly affects the user experience and the overall practicality of the equipment. However, the current design of embedded LED lights for freezers still has multiple technical shortcomings, making it difficult to meet the requirements of high efficiency, stability, and long-term use. The specific technical background is as follows: From the perspective of basic functionality, traditional embedded LED lights in freezers generally suffer from insufficient lighting stability and lack of ease of operation. On the one hand, the installation structure of most LED lights lacks targeted protective design, allowing condensation from the low-temperature environment inside the freezer to easily seep into the light strip, leading to short circuits. Furthermore, the installation and fixing methods for the light strips are rudimentary, making them prone to loosening under the vibrations of frequent opening and closing of the freezer, causing fluctuations in brightness or even complete shutdown. On the other hand, freezer door handles are mostly exposed, which not only easily accumulates dust and grease, increasing cleaning difficulty, but also occupies space around the cabinet. Moreover, the connection structure between some door handles and the cabinet door lacks stability, leading to jamming during long-term use and affecting operational smoothness, making it difficult to simultaneously meet the dual core requirements of "stable lighting" and "easy operation."

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an embedded LED light for rounded corner doors. Utility Model Content

[0004] This invention provides an embedded LED light for rounded corner doors to overcome the aforementioned defects in the prior art.

[0005] The purpose and function of this utility model, which provides an embedded LED light for a rounded corner door, are achieved through the following specific technical means: An embedded LED light for a rounded corner door includes: a freezer door, wherein the freezer door has an inner mounting groove, the inner mounting groove is fitted with glass, and the back of the freezer door has a back recess groove, wherein an inner box assembly is fixedly installed inside the back recess groove; The inner box assembly includes a mounting inner box with a trapezoidal bottom. An LED light strip is fixedly installed inside the mounting inner box, and the mounting inner box ensures that the LED light strip is waterproof and enhances heat dissipation.

[0006] In a further technical solution, the freezer door includes a rounded corner door, an upper cover is bolted to the top of the rounded corner door, an inner mounting groove is provided between the rounded corner door and the upper cover, and glass is fixedly installed inside the inner mounting groove.

[0007] A further technical solution is that a hidden door handle is fixedly installed on the outside of the rounded corner door, and a pivot assembly is fixedly installed on the bottom of the rounded corner door.

[0008] In a further technical solution, the rotating shaft assembly includes a mounting base plate, which is fixedly connected to the bottom of the rounded corner door, and a rotating central shaft is fixedly connected to the mounting base plate.

[0009] In a further technical solution, an installation cavity is installed inside the back groove, and an inner box assembly is installed inside the installation cavity. The upper surface of the inner box assembly is rectangular, the lower surface of the inner box assembly is trapezoidal, the inner box assembly is slightly smaller than the back groove, and a gap is provided between the inner box assembly and the side wall of the back groove.

[0010] In a further technical solution, the inner box assembly includes an inner mounting cavity, an inner mounting box is fixedly installed inside the inner mounting cavity, and an LED light strip is fixedly installed inside the inner mounting box.

[0011] In a further technical solution, a heat dissipation fin is fixedly connected between the inner box assembly and the back groove, and the connecting post of the heat dissipation fin is attached to the outer side of the glass.

[0012] In a further technical solution, a transparent cover plate is fixedly connected to the opening of the inner box assembly and the back groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses an embedded LED light for rounded corner doors. The inner box assembly secures and protects the LED light strip (waterproof design prevents short circuits due to moisture, and the trapezoidal bottom enhances installation stability). Combined with the light transmission and protection of the transparent cover, it ensures that the LED light strip can emit light stably after being powered on. The light is effectively projected through the glass, providing clear illumination for the freezer and meeting the user's needs for the core function of the device.

[0014] This utility model provides an embedded LED light for rounded corner doors, which achieves a solution through multiple synergistic structures: one end of the heat dissipation fins is attached to the inner box to absorb the heat from the LED strip, while the other end is conducted to the glass through a connecting post to increase its surface temperature and suppress water vapor formation. At the same time, the gap between the inner box assembly and the back recess forms a natural airflow channel to accelerate heat dissipation. The sealing and thermal conductivity design of the inner box further assists in heat dissipation. The dual heat dissipation path not only eliminates the impact of water vapor on illumination but also avoids the problems of brightness decay and shortened lifespan of the LED strip due to heat accumulation, breaking through the limitations of traditional embedded LED lights in freezer scenarios.

[0029] Example: As attached Figure 1 To be continued Figure 8 As shown: This utility model provides an embedded LED light for a rounded corner door.

[0030] See attached document Figure 1 To be continued Figure 8 The refrigerator door 1 includes: a refrigerator door 1, an inner mounting groove 13 is provided inside the refrigerator door 1, glass is installed inside the inner mounting groove 13, and a back recess groove 15 is provided on the back of the refrigerator door 1, and an inner box assembly 3 is fixedly installed inside the back recess groove 15. The inner box assembly 3 includes a mounting inner box 34 with a trapezoidal bottom. An LED light strip 33 is fixedly installed inside the mounting inner box 34. The mounting inner box 34 ensures the waterproofing and enhances heat dissipation of the LED light strip 33. On the one hand, it can prevent condensation in the freezer or external moisture from entering the LED light strip 33 and causing short circuit faults, thus ensuring the electrical safety of the LED light strip 33. On the other hand, it can quickly dissipate the heat generated by the LED light strip 33 during operation, preventing heat accumulation from affecting the luminous efficiency and lifespan of the light strip. At the same time, the trapezoidal bottom structure makes the mounting inner box 34 more compatible with the mounting cavity 32, making the installation more stable and facilitating heat conduction to the surroundings.

[0031] Preferred options are shown in the appendix. Figure 1 and appendix Figure 2 The freezer door 1 includes a rounded corner door 11. An upper cover 12 is bolted to the top of the rounded corner door 11. An inner mounting groove 13 is provided between the rounded corner door 11 and the upper cover 12. Glass is fixedly installed inside the inner mounting groove 13. The design of the rounded corner door 11 can improve the overall aesthetics of the freezer door, while avoiding sharp corners from causing bumps and damage, and ensuring safety in use. The upper cover 12 is easy to disassemble and maintain by being fixed with bolts. The glass in the inner mounting groove 13 can not only cooperate with the LED light strip 33 to achieve a light transmission and lighting effect, but also protect the internal structure of the inner mounting groove, reducing the entry of dust and moisture.

[0032] Preferred options are shown in the appendix. Figure 1 and appendix Figure 2 A concealed door handle 14 is fixedly installed on the outer side of the rounded corner door 11, and a pivot assembly 2 is fixedly installed on the bottom of the rounded corner door 11. The concealed door handle 14 can keep the surface of the freezer door flat and beautiful, avoiding the disadvantages of traditional exposed handles that are easy to accumulate dust and occupy space, while improving the overall sealing of the door. The pivot assembly 2 at the bottom provides stable rotation support for the opening and closing of the freezer door, ensuring the smoothness and stability of the door opening and closing process.

[0033] Preferred options are shown in the appendix. Figure 5 The rotating shaft assembly 2 includes a mounting base plate 21, which is fixedly connected to the bottom of the rounded corner door 11. A rotating central shaft 22 is fixedly connected to the mounting base plate 21. The mounting base plate 21 can increase the contact area between the rotating shaft assembly 2 and the bottom of the rounded corner door 11, improve the connection's firmness, and prevent the connection from loosening due to long-term opening and closing. The rotating central shaft 22 provides precise axial positioning for the rotation of the freezer door, ensuring that the opening and closing angle of the freezer door is controllable and that there is less chance of jamming or deviation during rotation.

[0034] Preferred options are shown in the appendix. Figure 3 and appendix Figure 4An inner mounting cavity 32 is installed inside the back groove 15, and an inner box assembly 3 is installed inside the inner mounting cavity 32. The upper surface of the inner box assembly 3 is rectangular, and the lower surface of the inner box assembly 3 is trapezoidal. The inner box assembly 3 is slightly smaller than the back groove 15, and there is a gap between the inner box assembly 3 and the side wall of the back groove 15. The inner mounting cavity 32 can provide a stable installation space for the inner box assembly 3. The rectangular upper surface is easy to fit and position with the top of the inner mounting cavity 32, while the trapezoidal lower surface is conducive to the downward conduction and dispersion of heat. The gap between the inner box assembly 3 and the side wall of the back groove 15 can form a natural heat dissipation channel, which, together with air circulation, achieves passive heat dissipation and further improves the overall heat dissipation effect.

[0035] Preferred options are shown in the appendix. Figure 5 and appendix Figure 8 The inner box assembly 3 includes an inner mounting cavity 32, inside which an inner mounting box 34 is fixedly installed. Inside the inner mounting box 34, an LED light strip 33 is fixedly installed. The inner mounting cavity 32 can provide secondary protection for the inner mounting box 34, reducing the impact of external impacts on the LED light strip 33. The sealing structure of the inner mounting box 34 can further enhance the waterproof protection level of the LED light strip 33. At the same time, the thermal conductivity of its material can quickly transfer the heat of the light strip, ensuring that the LED light strip 33 works stably in a suitable temperature environment and improving the uniformity and continuity of lighting.

[0036] Preferred options are shown in the appendix. Figure 8 The inner box assembly 3 is fixedly connected to the back groove 15 with heat dissipation fins. The connecting posts of the heat dissipation fins are attached to the outer side of the glass. The heat dissipation fins can greatly increase the heat dissipation area and accelerate the heat dissipation rate. The design of the connecting posts being attached to the outer side of the glass can conduct the heat generated by the LED light strip 33 to the glass. The low temperature environment of the glass can be used to achieve rapid heat exchange. This can not only effectively eliminate condensation on the glass surface and ensure the lighting transmission effect, but also further reduce the operating temperature of the LED light strip 33 and extend its service life.

[0037] Preferred options are shown in the appendix. Figure 8 A transparent cover plate 31 is fixedly connected to the opening of the inner box assembly 3 and the back groove 15. The transparent cover plate 31 will not block the light of the LED light strip 33, ensuring the lighting effect, and can also protect the inner box assembly 3, heat dissipation fins and other structures inside the back groove 15, preventing dust and debris from entering and affecting the heat dissipation and lighting functions. At the same time, it can also enhance the sealing of the back groove opening and improve the overall waterproof and dustproof capabilities.

[0038] Specific usage method of this utility model: Before using the embedded LED light device on this rounded corner door, the device and the freezer must be assembled together: the freezer door 1 is fixedly connected to the corresponding position of the freezer body through the mounting base plate 21 of the bottom pivot assembly 2, ensuring that the rotating central shaft 22 is precisely matched with the rotating structure of the freezer body, ensuring smooth opening and closing of the freezer door; after assembly, the power supply line of the freezer is electrically connected to the LED light strip 33 installed inside the inner box 34 in the inner box assembly 3, ensuring that the circuit is conductive and the contact is stable, providing continuous power support for the LED light strip to emit light.

[0039] When the device is in normal use, the operator can open and close the freezer door by pressing the concealed door handle 14 on the outside of the rounded corner door 11. The concealed door handle design avoids the problems of dust accumulation and space occupation of traditional exposed handles without affecting the ease of operation. At the same time, it reduces the leakage of cold air from the freezer, in conjunction with the sealing structure of the freezer door. At this time, the LED light strip 33 connected to the freezer power supply starts to emit light. The light passes through the transparent cover plate 31 at the opening of the back recess 15 (the transparent cover plate does not block the light and can prevent dust and moisture from entering the back recess), and then passes through the glass in the inner mounting groove 13 to project onto the inside of the freezer or the outside of the door, realizing the lighting function. This makes it easier for the operator to observe the items stored in the freezer in low-light environments, improving the ease of use.

[0040] During continuous operation, the glass surface of the inner mounting tray 13 is prone to condensation due to the temperature difference between the low temperature inside the freezer and the external environment. If not addressed promptly, this condensation will block the LED light strip's illumination, affecting the lighting effect. Simultaneously, the LED light strip 33 continuously generates heat during prolonged illumination. If this heat accumulates and cannot dissipate quickly, it will not only reduce the LED light strip's luminous efficiency (e.g., causing brightness decay) but also accelerate the aging of internal components, shortening its lifespan. To address these issues, this device achieves both condensation elimination and efficient heat dissipation through a multi-layered structural synergy: First, the heat dissipation fins, which are fixedly connected between the inner box assembly 3 and the back recess 15, play a crucial role. Made of a highly thermally conductive material, one end of the heat dissipation fins is tightly fitted to the inner box 34, quickly absorbing the heat generated by the LED strip 33. Simultaneously, the multi-piece structure of the heat dissipation fins significantly increases the contact area with air, accelerating heat diffusion into the interior space of the back recess 15. Second, the connecting posts of the heat dissipation fins are tightly fitted to the outer side of the glass, conducting the absorbed heat to the glass surface and raising its temperature above the dew point. This effectively suppresses the formation of condensation mist, keeping the glass surface dry even in scenarios where the freezer is frequently opened and closed and the temperature difference is large, ensuring the transparency of the lighting light. In addition, the size of the inner box component 3 is slightly smaller than the back groove 15, so that an annular gap is formed between the inner box component and the side wall of the back groove. This gap can serve as a natural heat dissipation airflow channel. When the air flows in the gap, it can carry away the heat diffused by the heat dissipation fins, further reducing the internal temperature of the back groove, forming a complete heat dissipation path of "heat generation - fin absorption - bidirectional conduction (air + glass) - airflow channel dissipation".

[0041] Meanwhile, the structural design of the inner mounting box 34 also ensures the stable operation of the device: its sealing performance effectively prevents condensation and humid air inside the freezer from intruding into the LED light strip 33, avoiding short circuits, component corrosion, and other malfunctions, thus ensuring electrical safety; the trapezoidal structure at the bottom of the inner mounting box not only improves its compatibility with the inner mounting cavity 32, making the installation more stable, but also guides heat to diffuse evenly in all directions, improving overall heat dissipation efficiency in conjunction with the heat dissipation fins. In addition, the upper cover 12 is fixed to the rounded corner door 11 with bolts, which facilitates the later inspection and maintenance of the glass and internal wiring in the inner mounting groove 13, enhances the structural sealing of the freezer door, reduces the impact of cold leakage on the glass temperature, and indirectly assists in eliminating water vapor.

[0042] In summary, through the synergistic effect of its components, this device effectively solves the problems of condensation and water mist obstruction and LED light strip heat dissipation while achieving stable lighting function. This not only ensures the continuity of lighting effect but also extends the lifespan of the LED light strip, thereby improving the practicality and reliability of the overall device.
