Description

Technical Field

[0001] This utility model belongs to the technical field of microwave oven equipment, specifically relating to lamps for microwave ovens. Background Technology

[0002] A microwave oven is a cooking appliance that heats food by allowing it to absorb microwave energy within a microwave field. The microwave generator in a microwave oven creates a microwave electric field within the oven cavity. Certain measures are taken to ensure this microwave electric field is distributed as evenly as possible within the cavity. Food is placed in this microwave electric field, and the cooking time and microwave electric field intensity are controlled by a central control unit to perform various cooking processes.

[0003] In traditional microwave ovens, the light fixture is suspended at the top inside the oven cavity. This makes it easy for food to collide with the light fixture while being handled, resulting in scratches or even damage to the light fixture, which can pose a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a microwave oven lamp. By setting a mounting bracket on the top surface of the inner cavity and fixing the LED light panel on the top of the mounting bracket, a through hole is opened on the top surface of the inner cavity, and a light-transmitting cover is placed over the through hole. A light guide component is set between the LED light panel and the light-transmitting cover, so that the light source shines into the inner cavity through the light guide component and the light-transmitting cover. This avoids placing the LED light panel inside the inner cavity, so that the removal of food will not be interfered with by the lamp. Even if the food touches the light-transmitting cover, it will not affect the normal use of the lamp.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A microwave oven light fixture includes an LED light panel and a mounting bracket. The mounting bracket is fixedly connected to the inner cavity, and the LED light panel is fixedly connected to the top of the mounting bracket. A light guide component is provided inside the mounting bracket, with its top matching the LED light panel. A through hole is provided on the top of the inner cavity corresponding to the light guide component, and the bottom of the light guide component is located in the through hole. A light-transmitting cover is provided on the top surface of the inner cavity at the through hole. This invention, by setting the mounting bracket on the top surface of the inner cavity and fixing the LED light panel to the top of the mounting bracket, and providing a through hole on the top surface of the inner cavity with a light-transmitting cover, and placing the light guide component between the LED light panel and the light-transmitting cover, illuminates the inner cavity with light through the light guide component and the light-transmitting cover. This avoids placing the LED light panel inside the inner cavity, ensuring that food handling is not interfered with by the light fixture, and even if food touches the light-transmitting cover, it does not affect the normal use of the light fixture.

[0007] Furthermore, the mounting bracket adopts a frame structure, with fixing parts extending from both sides of the bottom of the mounting bracket to form fixing parts, which are fixedly connected to the inner liner. The setting of the fixing parts increases the contact area between the mounting bracket and the inner liner, thereby improving the stability of the connection between the mounting bracket and the inner liner.

[0008] Furthermore, the light guide assembly includes a glass light guide column and a silicone sleeve for the light guide column. The silicone sleeve wraps around the outside of the glass light guide column, and the bottom of the silicone sleeve is fixedly connected to the mounting bracket, so that the top of the glass light guide column matches the LED light panel, and the bottom of the glass light guide column is located inside the light-transmitting cover. The silicone sleeve serves to install and fix the glass light guide column, while also providing protection. Because the silicone sleeve wraps around the glass light guide column, the glass light guide column transmits the light from the LED light panel into the inner liner, illuminating the interior. At the same time, the glass light guide column allows the LED light panel to be positioned on the outside of the inner liner, thus preventing collisions between the LED light panel and food during food handling, which could render the light fixture unusable.

[0009] Furthermore, the bottom of the light guide silicone sleeve has uniformly raised ridges forming limiting rings, and a groove is formed between two adjacent limiting rings. The top of the mounting bracket has a corresponding connecting hole, which matches the groove. The diameter of the limiting ring is larger than the diameter of the connecting hole. After the light guide silicone sleeve is inserted into the connecting hole, the limiting ring rests against the upper and lower sides of the mounting bracket. The groove formed between two adjacent limiting rings, combined with the connecting hole on the top of the mounting bracket, allows the light guide silicone sleeve to be inserted into the connecting hole, making the connecting hole and groove match and connect. Simultaneously, the limiting ring rests against the upper and lower ends of the top of the mounting bracket for limiting, thus achieving a fixed connection between the light guide silicone sleeve and the mounting bracket.

[0010] Furthermore, the silicone sleeve for the light guide post adopts a hollow structure with a mounting cavity at its center. This mounting cavity is matched and positioned to fit the glass light guide post, with the upper end of the glass light guide post located within the mounting cavity. The length of the silicone sleeve is shorter than the length of the glass light guide post, ensuring that the bottom of the glass light guide post is within the mounting frame. This mounting cavity facilitates the installation of the glass light guide post. Simultaneously, the shorter length of the silicone sleeve ensures that the bottom of the glass light guide post is not enclosed by the silicone sleeve and remains within the mounting frame. The mounting frame employs a frame-like structure, allowing the light source to converge and emit light from the light-transmitting cover.

[0011] Furthermore, the top of the silicone sleeve of the light guide post has a light-transmitting hole, the diameter of which is smaller than the diameter of the mounting cavity. The light source of the LED light panel is transmitted to the glass light guide post through the light-transmitting hole, and since the diameter of the light-transmitting hole is smaller than the diameter of the mounting cavity, it serves to limit the installation of the glass light guide post.

[0012] Furthermore, a mounting bracket is connected to the top of the mounting frame, and the mounting bracket is fitted onto the outside of the silicone sleeve of the light guide post.

[0013] Furthermore, the upper and lower ends of the mounting base are bent to form mounting plates and fixing plates. The mounting plates are located above the fixing plates, and the fixing plates are fixedly connected to the mounting frame. The top of the light guide post silicone sleeve extends corresponding to the mounting plates to form a base, which rests against the fixing plates. The fixing plates are used to mount the mounting base, and the mounting plates are used for limiting the installation of the light guide post silicone sleeve.

[0014] Furthermore, the base has dividing columns at both ends. The LED light-emitting panel is fixed to the mounting plate through the dividing columns, creating a gap between the bottom surface of the LED light-emitting panel and the top surface of the silicone sleeve of the light guide column. The dividing columns facilitate the installation of the LED light-emitting panel by creating a gap between it and the silicone sleeve of the light guide column.

[0015] Furthermore, the light-transmitting cover adopts a hemispherical structure, which allows the light from the LED light panel to diffuse in all directions, thereby illuminating the interior.

[0016] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0017] This invention involves mounting a bracket on the top surface of the inner liner and fixing an LED light panel to the top of the bracket. A through hole is made on the top surface of the inner liner, and a light-transmitting cover is placed over the through hole. A light guide component is installed between the LED light panel and the light-transmitting cover, allowing the light source to shine into the inner liner through the light guide component and the light-transmitting cover. This avoids placing the LED light panel inside the inner liner, ensuring that food handling is not interfered with by the light fixture. Even if the food touches the light-transmitting cover, it does not affect the normal use of the light fixture.

[0018] This utility model's light guide assembly includes a glass light guide column and a silicone sleeve for the light guide column. The silicone sleeve wraps around the outside of the glass light guide column, and the bottom of the silicone sleeve is fixedly connected to a mounting bracket, allowing the top of the glass light guide column to match the LED light panel. The bottom of the glass light guide column is located inside the light-transmitting cover. The silicone sleeve serves to install and fix the glass light guide column, while also providing protection. Because the silicone sleeve wraps around the glass light guide column, it allows the light from the LED light panel to be transmitted to the inner liner, illuminating the interior. Simultaneously, the glass light guide column allows the LED light panel to be positioned on the outside of the inner liner, thus preventing collisions with the LED light panel during food handling and avoiding malfunction of the light fixture.

[0019] In this invention, the base has dividing columns at both ends. The LED light-emitting panel is fixed to the mounting plate via the dividing columns, creating a gap between the bottom surface of the LED light-emitting panel and the top surface of the silicone sleeve of the light guide column. The dividing columns facilitate the installation of the LED light-emitting panel by creating a gap between it and the silicone sleeve of the light guide column. Attached Figure Description

Detailed Implementation

[0030] like Figures 1 to 8 As shown, the microwave oven lamp of this utility model includes an LED light panel 1 and a mounting bracket 2. The mounting bracket 2 is fixedly connected to the inner liner 20, and the LED light panel 1 is fixedly connected to the top of the mounting bracket 2. A light guide component 3 is provided inside the mounting bracket 2. The top of the light guide component 3 is matched with the LED light panel 1. A through hole 4 is provided on the top of the inner liner 20 corresponding to the light guide component 3. The bottom of the light guide component 3 is located in the through hole 4. A light-transmitting cover 5 is provided on the top surface of the inner liner 20 at the through hole 4.

[0031] The mounting bracket 2 adopts a frame structure, and fixing parts 6 extend from both sides of the bottom of the mounting bracket 2, which are fixedly connected to the inner liner 20. The setting of the fixing parts 6 increases the contact area between the mounting bracket 2 and the inner liner 20, thereby improving the stability of the connection between the mounting bracket 2 and the inner liner 20.

[0032] The light guide assembly 3 includes a glass light guide post 7 and a silicone sleeve 8. The silicone sleeve 8 wraps around the outside of the glass light guide post 7, and the bottom of the silicone sleeve 8 is fixedly connected to the mounting bracket 2, so that the top of the glass light guide post 7 matches the LED light panel 1, and the bottom of the glass light guide post 7 is located inside the light-transmitting cover 5. The silicone sleeve 8 serves to install and fix the glass light guide post 7, and also has a protective effect. Because the silicone sleeve 8 wraps around the glass light guide post 7, the glass light guide post 7 transmits the light from the LED light panel 1 to the inner liner 20, illuminating the inside of the inner liner 20. At the same time, the setting of the glass light guide post 7 allows the LED light panel 1 to be placed on the outside of the inner liner 20, thereby avoiding collisions with the LED light panel 1 during food handling, which could render the light fixture unusable.

[0033] The bottom of the light guide silicone sleeve 8 has uniformly raised protrusions forming limiting rings 9. A groove 10 is formed between two adjacent limiting rings 9. The top of the mounting bracket 2 has a corresponding connecting hole 11, which matches the groove 10. The diameter of the limiting ring 9 is larger than the diameter of the connecting hole 11. After the light guide silicone sleeve 8 is inserted into the connecting hole 11, the limiting ring 9 abuts against the upper and lower sides of the mounting bracket 2. The groove 10 formed between two adjacent limiting rings 9, combined with the connecting hole 11 on the top of the mounting bracket 2, allows the light guide silicone sleeve 8 to be inserted into the connecting hole 11, making the connecting hole 11 match and connect with the groove 10. Simultaneously, the limiting ring 9 abuts against the upper and lower ends of the top of the mounting bracket 2 for limiting, thereby achieving a fixed connection between the light guide silicone sleeve 8 and the mounting bracket 2.

[0034] The light guide silicone sleeve 8 has a hollow structure, with a mounting cavity 12 at its center. The mounting cavity 12 is matched with the glass light guide 7, with the upper end of the glass light guide 7 located inside the mounting cavity 12. The length of the light guide silicone sleeve 8 is shorter than the length of the glass light guide 7, so that the bottom of the glass light guide 7 is located inside the mounting frame 2. The mounting cavity 12 facilitates the installation of the glass light guide 7. At the same time, the shorter length of the light guide silicone sleeve 8 ensures that the bottom of the glass light guide 7 is not covered by the light guide silicone sleeve 8 and is located in the mounting frame 2. The mounting frame 2 has a frame-shaped structure, allowing the light source to be focused and emitted from the light-transmitting cover 5.

[0035] The top of the silicone sleeve 8 of the light guide post is provided with a light-transmitting hole 13, the diameter of which is smaller than the diameter of the mounting cavity 12. The light source of the LED light-emitting board 1 is conducted to the glass light guide post 7 through the light-transmitting hole 13. At the same time, the diameter of the light-transmitting hole 13 is smaller than the diameter of the mounting cavity 12, thus providing a limiting effect for the installation of the glass light guide post 7.

[0036] The top of the mounting bracket 2 is connected to a fixing seat 14, which is fitted onto the outside of the silicone sleeve 8 of the light guide post.

[0037] The upper and lower ends of the mounting base 14 are bent to form mounting pieces 15 and fixing pieces 16. The mounting piece 15 is located above the fixing piece 16, and the fixing piece 16 is fixedly connected to the mounting bracket 2. The top of the light guide silicone sleeve 8 extends to form a base 17 corresponding to the mounting piece 15, and the base 17 abuts against the fixing piece 16. The fixing piece 16 is used to mount the mounting base 14, and the mounting piece 15 is used for limiting the mounting of the light guide silicone sleeve 8.

[0038] The base 17 has partition columns 18 at both ends. The LED light-emitting panel 1 is fixed to the mounting plate 15 through the partition columns 18, so that a gap is formed between the bottom surface of the LED light-emitting panel 1 and the top surface of the light guide silicone sleeve 8. The partition columns 18 create a gap between the LED light-emitting panel 1 and the light guide silicone sleeve 8, which facilitates the installation of the LED light-emitting panel 1.

[0039] The light-transmitting cover 5 adopts a hemispherical structure, which allows the light from the LED light panel 1 to be dispersed, thereby illuminating the interior liner 20.

[0040] This utility model sets up a mounting bracket 2 on the top surface of the inner liner 20 and fixes the LED light panel 1 on the top of the mounting bracket 2. A through hole 4 is opened on the top surface of the inner liner 20, and a light-transmitting cover 5 is placed over the through hole 4. A light guide component 3 is set between the LED light panel 1 and the light-transmitting cover 5. The light source is irradiated into the inner liner 20 through the light guide component 3 and the light-transmitting cover 5. This avoids placing the LED light panel 1 in the inner liner 20, so that the food can be taken out without being disturbed by the light fixture. Even if the food touches the light-transmitting cover 5, it will not affect the normal use of the light fixture.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
