[0016] In one of the embodiments, the cross section of the lampshade gradually increases in the direction close to the inner container.

[0017] The second aspect of the present application provides a multifunctional cooking equipment comprising the above-mentioned lighting structure.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 , the present application first provides a lighting structure, comprising inner container 100, stove bottom plate 200 and lamp body assembly 10;The stove bottom plate 200 is fixed on the top of the inner container 100, and the stove bottom plate 200 is provided with a heat dissipation fan 210 inside, and the stove bottom plate 200 is also provided with an air inlet 220 communicating with the outside;The lamp body assembly 10 comprises a lamp plate 11, a heat sink 12, a light guide column 13 and a window glass 14, the lamp plate 11 is fixed in the stove bottom plate 200, the heat sink 12 is fixed with the lamp plate 11, the inner container 100 is provided with a window hole, the window glass 14 is fixed on the inner container 100 to seal the window hole, one end of the light guide column 13 corresponds to the lamp plate 11, and the other end penetrates through the stove bottom plate 200 to the outside of the inner container 100 and corresponds to the window glass 14.

[0030] In the present application, by pasting the heat sink 12 on the lamp plate 11, the heat of the lamp plate 11 can be conducted to the heat sink 12, so as to increase the heat dissipation area of the lamp plate 11. In addition, the heat dissipation fan 210 can suck the outside air into the stove bottom plate 200 through the air inlet 220, and the outside air flow entering the stove bottom plate 200 will exchange heat with the heat sink 12, so as to realize efficient heat dissipation of the lamp plate 11, and avoid the light decay caused by excessive heat accumulation and high temperature of the lamp plate 11.

[0031] Specifically, the light emitted by the lamp plate 11 is conducted to the position of the window glass 14 through the light guide column 13, and passes through the window glass 14 to realize the illumination of the inside of the inner container 100.

[0032] As shown in Figure 1 In some embodiments, the heat dissipation fin 12 is located between the air inlet 220 and the heat dissipation fan 210, so that the heat dissipation fin 12 is located on the air inlet path of the heat dissipation fan 210, and the air flow can be fully heat exchanged with the heat dissipation fin 12, thereby further improving the heat dissipation effect of the lamp panel 11.

[0033] As shown in Figure 1 In some embodiments, the lamp panel 11 and the heat dissipation fin 12 are located in the stove bottom plate 200 close to the air inlet 220 and opposite to the air inlet 220.

[0034] When the external airflow enters the stove bottom plate 200 through the air inlet 220, the temperature of the airflow will gradually rise with the heat exchange of the airflow and the devices on the path, thereby reducing the heat exchange capacity. By arranging the heat dissipation fin 12 close to the air inlet 220 and opposite to the air inlet 220, the airflow entering the stove bottom plate 200 can first exchange heat with the heat dissipation fin 12, thereby achieving excellent heat dissipation effect.

[0035] As shown in Figure 1 In some embodiments, the projections of the stove bottom plate 200 on both sides in the vertical direction protrude from the inner container 100, and the lamp panel 11 and the heat dissipation fin 12 are located in the protruding part of the stove bottom plate 200. On the one hand, the stove bottom plate 200 at the protruding position on both sides has good rigidity and is fixed relatively firmly, and on the other hand, there are fewer other components at this position and close to the edge, which is convenient for production line workers to install and operate.

[0036] As shown in Figure 1 In some embodiments, the light guide column 13 is in a straight strip shape. Compared with other special-shaped structures, the light guide column 13 in a straight strip shape has small loss of light efficiency, low cost, and can effectively improve the brightness of the lighting structure of the present application.

[0037] As shown in Figure 1 and Figure 3 In some embodiments, the fins of the heat dissipation fin 12 are parallel to the airflow direction inside the stove bottom plate 200. Such arrangement can increase the contact area between the airflow and the fins as much as possible, thereby further improving the heat dissipation capacity of the lighting structure of the present application.

[0038] In some embodiments, the heat dissipation fin 12 is an aluminum-based heat dissipation fin, which has strong heat conduction performance. Of course, the heat dissipation fin 12 can also be selected from other materials as long as it can meet the heat dissipation demand of the lamp panel 11.

[0039] As shown in Figure 1 and Figure 3As shown, in some embodiments, the lamp body assembly 10 further includes a lampshade 15, which is disposed outside the window glass 14 and fixed to the outer wall of the inner tank 100. The light guide column 13 is inserted into the lampshade 15, and the lampshade 15 can reflect and guide the light at the exit position of the light guide column 13 to the window glass 14, so as to reduce light loss and improve the lighting brightness of the lighting structure of the present application.

[0040] Preferably, the cross-section of the lampshade 15 gradually increases in the direction approaching the inner tank 100, so as to maximize the light guiding effect of the lampshade 15 toward the inner tank 100, that is, by reducing the number of reflections required for the light at the exit position of the light guide column 13 to be emitted to the window glass 14, thereby reducing the light loss in the reflection process, and thus achieving the effect of improving the lighting brightness.

[0041] A second aspect of the present application provides a multifunctional cooking device comprising the above-mentioned lighting structure.

[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
