Description

Technical Field

[0001] The utility model belongs to the technical field of cooking equipment, and in particular relates to an internal lighting structure of cooking equipment. Background Art

[0002] Currently, there are two main types of lighting structures for steam ovens on the market. The first type is to install the lighting lamp on the door body, such as the "Lighting Structure of a Cooking Device" disclosed in the Chinese utility model patent with application number CN202221590700.7 (authorization announcement number CN218074495U). The lighting lamp of the cooking device is installed on the door frame. During the use of this type of steam oven, when the door body is in the closed state, the lighting effect of the lighting lamp on the inside of the steam oven is better, and the user can observe the status of the food being cooked in the steam oven through the glass door. However, when the door body is opened, the lighting effect of the lighting lamp on the inside of the steam oven will be significantly reduced, which will affect the user's judgment on the status of the food being cooked. At the same time, all processes of taking and placing food in the steam oven must be carried out with the door body open, resulting in poor user experience.

[0003] The second type is to install the lighting lamp in the box, such as the "Internal Lighting Structure of a Steamer and Steam Oven" disclosed in the Chinese utility model patent with application number CN202120392197.3 (authorization announcement number CN214172052U). The lighting structure includes a circular plastic bracket arranged on the side of the steamer inner tank, and a honeycomb-shaped concave transparent panel is arranged in the plastic bracket. An LED light board is arranged in the plastic bracket inside the transparent panel. The light emitted by the LED light board can fill the internal space of the steamer through the transparent panel. Since the lighting lamp is located in the box, there is a defect of higher temperature resistance requirements and the service life of the lighting lamp is relatively short. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an internal lighting structure of a cooking device, which can not only improve the lighting effect but also prolong the service life.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an internal lighting structure of a cooking device, including a box body and a lighting lamp, the box body includes an outer shell and an inner shell arranged inside the outer shell, the inner shell is provided with a first light-transmitting window, the lighting lamp is arranged between the outer shell and the inner shell, and the light emitted by the lighting lamp passes through the first light-transmitting window and irradiates into the inner shell.

[0006] Preferably, a window is provided on the inner shell, and the first light-transmitting window comprises a first light-transmitting plate, and the first light-transmitting plate is provided at the window.

[0007] Preferably, a pressure plate is detachably provided on the outer surface of the inner shell, and the outer surface of the inner shell cooperates with the pressure plate to press on two opposite sides of the first light-transmitting plate. A light-transmitting port is provided on the pressure plate, and the light emitted by the lighting lamp passes through the light-transmitting port, the first light-transmitting plate, and the window in sequence and then irradiates into the inner shell.

[0008] Preferably, the first light-transmitting plate and the inner shell are sealed by a high-temperature-resistant rubber gasket, and the rubber gasket is arranged around the window.

[0009] Preferably, a side surface of the inner shell is protruded toward the interior of the inner shell to form a mounting portion, and the window is provided on the mounting portion.

[0010] Preferably, a second light-transmitting window is provided between the first light-transmitting window and the lighting lamp, a first heat-insulating cavity is formed between the first light-transmitting window and the second light-transmitting window, and a second heat-insulating cavity is formed between the second light-transmitting window and the lighting lamp.

[0011] Preferably, the second light-transmitting window includes a second light-transmitting plate and a frame, a slot is provided on the inner side of the frame, an edge of the second light-transmitting plate is inserted into the slot, and the frame is connected to the inner shell and / or the outer shell.

[0014] Preferably, a mounting bracket is provided on the inner side of the outer shell, and the lighting lamp is provided on a side of the mounting bracket facing the inner shell.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. By setting the lighting lamp on the box body, the lighting lamp will not move with the door body. During the use of the cooking device, the lighting lamp can always stably and evenly illuminate the internal environment of the inner shell, with a better lighting effect, avoiding the inconvenience caused to the user by insufficient lighting;

[0017] 2. By arranging the lighting lamp between the outer shell and the inner shell, and providing a first light-transmitting window on the inner shell, light emitted by the lighting lamp can be irradiated into the inner shell through the first light-transmitting window. Thus, while ensuring the lighting effect, the lighting lamp is prevented from being directly exposed to the high temperature environment inside the inner shell. This greatly reduces the impact of high temperatures generated during use of the cooking equipment on the lighting lamp, helping to extend the service life of the lighting lamp.

[0018] 3. By adding a second light-transmitting window between the first light-transmitting window and the lighting lamp, a first heat-insulating cavity is formed between the first light-transmitting window and the second light-transmitting window, and a second heat-insulating cavity is formed between the second light-transmitting window and the lighting lamp. The first heat-insulating cavity and the second heat-insulating cavity can effectively isolate the internal high-temperature environment, reduce the high temperature in the inner shell from being transferred to the lighting lamp, and help further extend the service life of the lighting lamp.

[0028] Example 1: Figures 1 to 3 As shown, an internal lighting structure of a cooking device includes a housing 1 and a lighting lamp 2. The housing 1 includes an outer housing 11 and an inner housing 12 disposed within the outer housing 11. The inner housing 12 is provided with a first light-transmitting window 3. The lighting lamp 2 is disposed between the outer housing 11 and the inner housing 12. Light emitted by the lighting lamp 2 passes through the first light-transmitting window 3 and irradiates the inner housing 12. The first light-transmitting window 3 and the lighting lamp 2 are both strip-shaped and arranged vertically. The lighting lamp 2 is preferably an LED lamp, but other types of lamps may also be used.

[0029] In this embodiment, a window 121 is provided on the inner shell 12. The first light-transmitting window 3 includes a first light-transmitting plate 31. The first light-transmitting plate 31 is disposed at the window 121. The first light-transmitting plate 31 not only transmits light but also, to a certain extent, blocks the high temperature inside the inner shell 12 from diffusing outward, providing a heat-insulating effect. The first light-transmitting plate 31 is preferably made of glass, but other materials that are both light-transmitting and heat-resistant may also be used.

[0030] Conventionally, the front side of the outer shell 11 is provided with an opening and is rotatably connected to a door body 5. The first light-transmitting window 3 can be provided on any side of the inner shell 12. In order to avoid the light emitted by the lighting lamp 2 directly hitting the user's eyes and causing discomfort, the first light-transmitting layer is preferably provided on the left or right side of the front side of the inner shell 12.

[0031] It should be noted that one cooking device may be provided with one internal lighting structure, or may be provided with two or more internal lighting structures. When two internal lighting structures are provided, they may be provided in a bilaterally symmetrical manner.

[0032] Example 2: Figures 3 to 5 As shown, the rest of the parts are the same as those in Example 1, except that a pressure plate 13 is detachably provided on the outer surface of the inner shell 12, and the outer side surface of the inner shell 12 cooperates with the pressure plate 13 to press on two opposite side surfaces of the first light-transmitting plate 31, and a light-transmitting port 131 is provided on the pressure plate 13. The light emitted by the lighting lamp 2 passes through the light-transmitting port 131, the first light-transmitting plate 31, and the window 121 in sequence and then irradiates into the inner shell 12.

[0033] In this embodiment, a plurality of welding nuts 123 are welded on the outer surface of the inner shell 12, and a plurality of mounting holes 132 are provided on the pressure plate 13. The plurality of mounting holes 132 correspond one-to-one to the plurality of welding nuts 123. After the bolts pass through the mounting holes 132, they are threadedly connected with the corresponding welding nuts 123.

[0034] In order to prevent the fumes generated in the inner shell 12 from penetrating into the space between the inner shell 12 and the outer shell 11 through the window 121 during the use of the cooking device, the first light-transmitting plate 31 and the inner shell 12 are further sealed by a high-temperature resistant rubber gasket (not shown in the figure). The rubber gasket is arranged around the window 121 to achieve a good sealing effect and good reliability.

[0035] In order to allow the lighting lamp 2 to illuminate the internal space of the inner shell 12 in a wider range or to prevent the user from seeing the lighting lamp 2 from the outside of the cooking device, further, the side of the inner shell 12 is protruded toward the inside of the inner shell 12 to form a mounting portion 122, and a window 121 is provided on the mounting portion 122. The side of the inner shell 12 can be any side, depending on the structural design of the cooking device. For example, the mounting portion 122 is provided in the front area of ​​the right side of the inner shell 12. The mounting portion 122 includes two folded edges 1221 distributed along the front-to-back direction and connected to each other. The window 121 is provided on the folded edge 1221 located on the rear side, and the front side of the pressure plate 13 is connected to the folded edge 1221 located on the front side. At this time, the lighting lamp 2 can not only illuminate the internal space of the inner shell 12 in a wider range, but also prevent the user from seeing the lighting lamp 2 from the outside of the cooking device. The user can see the light but not the lamp, which helps to improve the user experience. Among them, the cross section of the folded edge 1221 can be strip-shaped (see Figure 3 ), or it can be curved (see Figure 5 Of course, the mounting portion 122 may also be provided in the rear region of the right side of the inner shell 12. In this case, the window 121 is provided on the folded edge 1221 located at the front side.

[0036] Example 3: Figure 2 、 Figure 3 and Figure 6 As shown, the remaining parts are the same as those of the first embodiment, except that a second light-transmitting window 4 is provided between the first light-transmitting window 3 and the illuminating lamp 2. A first heat-insulating cavity 14 is formed between the first light-transmitting window 3 and the second light-transmitting window 4, and a second heat-insulating cavity 15 is formed between the second light-transmitting window 4 and the illuminating lamp 2. The first heat-insulating cavity 14 and the second heat-insulating cavity 15 effectively isolate the internal high-temperature environment and reduce the transfer of high temperatures within the inner housing 12 to the illuminating lamp 2. The second light-transmitting window 4 can be fixed in various ways and can be connected to the inner housing 12 and / or the outer housing 11, preferably connected to the inner housing 12.

[0037] In this embodiment, the second light-transmitting window 4 includes a second light-transmitting plate 41 and a frame 42.
