Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electric ovens, specifically to a lighting device installation structure for an electric oven. Background Technology
[0002] Electric ovens, widely used cooking appliances in modern kitchens, typically require internal lighting so users can monitor the cooking process. When an electric oven starts operating, the internal temperature rises rapidly and remains at a high level for an extended period. Traditional lighting fixtures have poor heat resistance, leaving the lamps directly exposed to the high temperature of the interior without effective insulation or heat dissipation. This further increases the heat load on the lamps, exacerbating the risk of damage and shortening their lifespan.
[0003] Secondly, because the lighting fixtures need to be installed inside the confined space of an electric oven, the installation method is usually quite complex, requiring screws or clips for fixing. The installation and disassembly process is time-consuming and labor-intensive, and may even require specialized tools and techniques. When the light fixtures are damaged and need replacement, users often find it difficult to do so themselves, increasing the complexity and cost of maintenance. Furthermore, due to their traditional single-location installation, the light fixtures often only illuminate a specific area, resulting in uneven lighting, localized overbrightness, or glare, affecting the user's accurate judgment of the food's cooking status and consequently impacting the quality of the food. Utility Model Content

[0026] The present invention will be further described in detail below with reference to the accompanying drawings. A lighting device mounting structure for an electric oven includes an inner cavity 1 and a protective seat 2 mounted on the outer wall of the inner cavity 1. The protective seat 2 is hollow, forming a mounting cavity 21, in which a lighting device 4 is disposed. A light-diffusing plate 6 is installed covering the port of the mounting cavity 21. The inner cavity 1 has several light-transmitting holes 11 extending through its side wall, and the light-diffusing plate 6 covers the outside of the light-transmitting holes 11. Mounting plates 3 extend from the left and right sides of the mounting cavity 21, and insertion holes 31 are formed through the mounting plates 3. The side wall of the inner cavity 1 is bent towards the protective seat 2 to form an insertion plate 12, which is inserted into the insertion hole 31 to achieve quick installation of the lighting device 4. The protective seat 2 is provided with heat dissipation holes 22.
[0027] In this electric oven, a mounting cavity is formed inside the protective base, and the lighting device is installed inside this cavity. The protective base is installed on the outer wall of the inner cavity, effectively isolating the lighting device from the high temperature, oil stains, and humid environment inside the oven. This significantly protects the lighting device and avoids the problem of easy damage due to prolonged high temperatures in existing technologies, effectively extending the lifespan of the lighting device. Secondly, a light-diffusing plate covers the port of the mounting cavity. Corresponding to the position of the light-diffusing plate, light-transmitting holes are opened on the side wall of the inner cavity. The light emitted by the lighting device is diffused through the light-diffusing plate and enters the interior of the oven through the light-transmitting holes, illuminating the food inside. The light-diffusing plate effectively diffuses the light evenly, avoiding problems such as uneven lighting and localized overbrightness in existing technologies, improving the clarity and comfort for users to observe food. The light-diffusing plate also has a certain heat insulation property, effectively preventing heat dissipation from the oven interior to the lighting device, protecting it from direct damage from high temperatures.
[0028] Furthermore, to facilitate the installation and connection of the protective base, mounting plates extend to the left and right sides of the mounting cavity, with insertion holes extending through these plates. Corresponding to these insertion holes, insertion plates are formed by bending along the side wall of the inner liner towards the protective base. These insertion plates engage with the insertion holes, enabling rapid positioning and installation of the lighting device. Utilizing this simple insertion method, users can achieve quick installation and disassembly without complex tools. The installation process is simple and fast, facilitating maintenance and replacement of the lighting device.
[0029] Furthermore, the protective base is equipped with heat dissipation holes, which provide a clear heat dissipation channel for the lighting device, effectively dissipating the heat generated by the lighting device during operation, significantly reducing the operating temperature of the lighting device, and further ensuring the working stability of the lighting device and extending its service life.
[0030] The socket 31 extends vertically, with a height greater than that of the insert plate 12; the cross-sectional width of the socket 31 is greater than that of the insert plate 12. The vertical extension of the socket matches the shape of the insert plate, and both its height and cross-sectional width are greater than those of the insert plate. This provides the insert plate with sufficient room to move when inserted, allowing for smoother and faster insertion and removal, improving the user's installation experience, reducing assembly difficulty, and preventing jamming during insertion due to excessive tightness. This ensures convenient installation and removal of the protective base.
[0031] The insert plate 12 has a clearance groove 13 extending through the inner liner 1 body on one side. The clearance groove on one side of the insert plate provides additional space for the insert plate to move, avoids interference between the insert plate and other components, and also provides the necessary manufacturing process space for bending and shaping the insert plate.
[0032] The upper and lower ends of the outer side of the mounting cavity 21 are inclined to form an air guide surface 23, and several heat dissipation holes 22 are provided through this air guide surface 23. In order to better guide the airflow, the upper and lower ends of the outer side of the mounting cavity are inclined to form an air guide surface, and the heat dissipation holes are distributed on this air guide surface. The inclined air guide surface better guides the airflow, forming natural convection, which quickly removes the heat generated by the lighting device, accelerates heat loss, further reduces the operating temperature of the lighting device, ensures the long-term stable operation of the lighting device in high-temperature environments, and effectively extends the service life of the lighting device.
[0033] The lighting device 4 includes a lamp 41 and a power cord 42 electrically connected to it. A mounting base 5 is provided around the power cord 42, and a mounting groove 24 is provided through one side of the protective base 2. The mounting base 5 passes through and is secured in the mounting groove 24. The lighting device includes a lamp 41 and a power cord electrically connected to it, with a mounting base provided around the power cord. The mounting base passes through and is secured in the mounting groove of the protective base, firmly fixing the power cord and preventing it from loosening due to vibration or accidental pulling, thus improving the reliability of the electrical connection. Furthermore, integrating the power cord into the mounting base makes the wiring neater, simplifies the overall installation process of the lighting device, reduces the risk of exposed power cords, and improves the safety of the electric oven.
[0034] The mounting base 5 has protruding locking seats 51 at its upper and lower ends. Correspondingly, the mounting groove 24 has locking holes 25 at its upper and lower ends. The locking screw passes through the locking holes 25 and connects to the locking seats 51 to lock the position of the lamp 41 within the protective base 2. The mounting base has protruding locking seats at its upper and lower ends, and locking holes are provided at the upper and lower ends of the mounting groove of the protective base. After the mounting base is engaged with the mounting groove, the locking screw passes through the locking holes and screws into the locking seats to achieve final locking of the mounting base. This prevents the mounting base, its power cord, or the lamp from loosening due to vibration or high temperature during long-term use, ensuring that the lighting device always maintains a precise and stable position and enhancing the long-term reliability of the product.
[0035] A through groove 26 is provided through one side wall of the protective base 2. This channel serves as an auxiliary heat dissipation channel, providing additional airflow path and enhancing the heat dissipation effect on the lighting device. It also provides a convenient passage for maintenance or observation of the interior of the lighting device.
[0036] The protective base 2 has openings 27 at its upper and lower ends bent towards the mounting cavity 21, and these openings 27 are connected to the mounting cavity 21. These openings, along with the heat dissipation holes, further enhance air convection, allowing hot air to escape through the upper opening and cool air to enter through the lower opening. This significantly improves heat dissipation within the mounting cavity, reduces localized heat buildup, and further protects the lighting device.
[0037] In summary: The lighting device is mounted on the outer wall of the oven's inner liner and built into the mounting cavity formed by the hollow protective base. This external mounting method completely isolates the lighting device from the high temperature, high humidity, and oily interior of the electric oven, avoiding the aging and damage caused by direct exposure of the lamps to harsh environments, as is the case with existing technologies. The protective base itself constitutes a robust physical barrier, further protecting the lamps.
[0038] When the lighting device is working, the light first passes through a light-diffusing plate at the mounting cavity port, which scatters the light, making it soft and uniform. Then, the diffused light passes through several pre-drilled holes on the inner wall of the oven cavity, finally entering the interior space of the oven to illuminate the food. This ensures that light enters the oven while the light-diffusing plate guarantees uniform lighting and visual comfort, avoiding the localized overbrightness or glare that can occur with traditional point light sources.
[0039] To facilitate installation and maintenance, mounting plates with insertion holes extend from both sides of the protective base, while the inner liner sidewalls are correspondingly bent to form insertion plates. Users simply plug the insertion holes on the protective base into the insertion plates on the inner liner to quickly position and install the lighting device, eliminating the cumbersome operation of traditional screws or complex clips. Furthermore, to ensure long-term operational stability, the power cord of the lighting device is fitted with a mounting base that snaps into the mounting groove of the protective base. Then, the locking seat on the mounting base engages with the locking hole in the mounting groove, and a locking screw is used for final fixation. This multi-layered fixing method of "plug-in + snap-in + screw locking" ensures that the lighting device maintains an extremely stable and reliable connection during long-term operation, vibration, or transportation of the electric oven, eliminating the risk of loosening and detachment, and greatly improving the product's safety and durability.
[0040] To address the heat generation issue inherent in traditional lighting fixtures, the protective base is equipped with ventilation holes, providing a basic channel for heat dissipation. Furthermore, the upper and lower edges of the mounting cavity are angled to form air guide surfaces, through which multiple ventilation holes pierce. These angled surfaces effectively guide airflow, creating a good natural convection cooling path. Simultaneously, the openings formed by the bending of the upper and lower edges of the protective base towards the mounting cavity further enhance air circulation, allowing hot air to rise and be expelled quickly, while cool air enters from below. This maximizes the heat dissipation efficiency of the lighting fixture, ensuring it maintains a low operating temperature even in high ambient temperatures around the electric oven, significantly extending its lifespan. This overcomes the weakness of existing lighting fixtures, which are prone to damage due to poor heat dissipation, and therefore can be widely adopted.
