Abstract
Description
Technical Field
[0001] This utility model relates to the field of oven electrical equipment technology, and in particular to a three-dimensional lighting fixture for ovens. Background Technology
[0002] In existing oven products, lighting systems are often simply designed, typically with a single light source located at the top or side of the oven interior. This design has several drawbacks: First, a single lighting element limits the illumination range and provides incomplete light coverage, easily creating shadows in the baking area. This makes it difficult for users to clearly and accurately observe the degree of baking, thus affecting cooking results. Second, the installation structure of existing lighting devices is mostly fixed, making disassembly and maintenance cumbersome and hindering the replacement of damaged lighting elements. Furthermore, some lighting devices have poor sealing performance, allowing the high temperatures generated during oven operation to penetrate into the lighting device, affecting the stability and lifespan of the lighting element. Utility Model Content
[0003] To address some of the problems existing in the prior art, this utility model provides a three-dimensional lighting fixture for ovens. This lighting fixture is suitable for various household or commercial ovens and can provide stable and uniform lighting for the baking area inside the oven, helping users to observe the baking status of food in real time.
[0004] To achieve the above objectives, this utility model provides a three-dimensional lighting fixture for an oven, including an oven. A first lighting fixture is installed at the top interior of the oven, and several second lighting fixtures are symmetrically arranged on the sides interior of the oven. The first lighting fixture includes a mounting base, on which a positioning guide block and a connecting slot are integrally formed for detachable installation with the top interior of the oven. A sealing shell is embedded in the mounting base, and the first lighting fixture is fitted inside the sealing shell. A mounting hole is also provided in the middle of the mounting base, and a transparent glass is embedded in the mounting hole, corresponding to the irradiation end of the first lighting fixture, for vertically irradiating the baking area downwards. The second lighting fixtures include second lighting fixtures, with connecting supports attached to both ends of the second lighting fixtures and installed on the sides interior of the oven through the connecting supports, for laterally irradiating the baking area.
[0005] In operation, the mounting base of the first lighting unit is first detachably installed to the top of the oven interior using an integrally molded positioning guide block and connecting slot. Then, a one-piece injection-molded sealing shell containing the first lighting unit is fitted onto the mounting base, ensuring a tight fit between the side of the sealing shell and the inner wall of the positioning guide block and connecting slot. A sealing ring is then installed between the sealing shell and the mounting base. Next, a transparent glass is inserted into the mounting hole in the center of the mounting base, aligning with the illumination end of the first lighting unit. Finally, multiple lighting bulbs with a high-temperature reflective coating on their inner walls are detachably connected to the interior of the first lighting unit via connecting threads at their tail ends, and then tightened and rotated. Position the light bulb so that the annular limiting protrusion on the outer end of the light bulb tightly abuts against the annular limiting step inside the first light bulb to form a double limiting fixation; then, attach the connecting brackets to both ends of the second light bulb and position it inside the oven side through the U-shaped groove on the connecting brackets. At the same time, thread the wires of the second light bulb through the through-type wiring groove inside the oven side. During operation, the wide-angle diffused light of the first light bulb shines vertically downward through the transparent glass onto the baking area, multiple light bulbs increase the lighting intensity and enhance the reflective effect with the help of the reflective coating, and the directional focused light of the second light bulb shines sideways onto the baking area. The two work together to achieve three-dimensional uniform lighting of the baking area.
[0006] The beneficial effects of this utility model are as follows: By setting a first lighting group at the top of the oven interior and several second lighting groups symmetrically arranged on the sides, a three-dimensional lighting system is constructed by combining the wide-angle diffused light characteristics of the first lighting group with the directional focusing light characteristics of the second lighting group. This effectively eliminates blind spots in the baking area, ensures uniform lighting, and allows users to clearly and in real time observe the baking status of the food. The first lighting group is detachably installed with the oven through a positioning guide block and a connecting slot. The lighting bulb adopts a double limiting structure with connecting threads, a ring-shaped limiting step, and a limiting protrusion, which not only ensures the accuracy and stability of the installation but also provides convenience for later maintenance and replacement. The combination of the sealing shell and the sealing ring improves the sealing performance of the device and prevents high-temperature penetration. The high-temperature resistant reflective coating on the inner wall of the lighting bulb not only enhances the reflective effect but also improves the high-temperature resistance of the components and extends their service life. The U-shaped groove design of the connecting support facilitates the quick positioning and installation of the second lighting group, and the through-type wiring channel makes the wire layout neat and orderly, reduces the installation difficulty, and improves the safety of use.
[0007] As a further improvement of this utility model, in order to improve the lighting intensity, enhance the reflective effect and adapt to the high temperature environment of the oven, and facilitate the replacement of damaged bulbs later; a plurality of lighting bulbs are evenly arranged inside the first lighting lamp, and the tail end of the lighting bulb is provided with a connecting thread and is detachably connected to the inside of the first lighting lamp through the connecting thread; the inner wall of the lighting bulb is also coated with a high temperature resistant reflective coating.
[0008] As a further improvement of this utility model, in order to ensure the accuracy of the installation of the first lighting lamp, improve the sealing performance, and effectively block the high temperature penetration of the oven, the sealing shell is integrally injection molded, and its interior is provided with a groove adapted to the first lighting lamp; the side end of the sealing shell is tightly fitted with the inner side wall of the positioning guide block and the connecting slot for precise positioning and installation of the first lighting lamp; a sealing ring is also provided between the sealing shell and the mounting base.
[0009] As a further improvement of this utility model, in order to effectively prevent the bulb from loosening or falling off and improve the stability of use, a limiting protrusion is also provided on the outer end of the lighting bulb, and the limiting protrusion is a ring structure; an annular limiting step is also provided inside the first lighting bulb, and the annular limiting step is adapted to the limiting protrusion; the lighting bulb is tightened and rotated to a preset position by connecting threads, and the limiting protrusion and the annular limiting step are tightly abutted to form a double limiting fixation.
[0010] As a further improvement of this utility model, in order to conceal the wiring and avoid direct contact with high temperature, while standardizing the wiring layout, improving the cleanliness of the oven interior, avoiding wire wear, and reducing safety hazards, a U-shaped groove is provided on the connecting support for installation and positioning, and a through-type wiring groove is also provided inside the side end of the oven; a wire is provided on the second lighting lamp and passes through the through-type wiring groove.
[0011] As a further improvement of this utility model, in order to eliminate blind spots in the baking area and improve the uniformity of lighting by combining two types of lighting, making it easier for users to observe the baking status of food more clearly; the first lighting lamp adopts a wide-angle diffused light type, and the second lighting lamp adopts a directional focused light type.
