For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0058] As Figure 1 , Figure 4 , Figure 7 , Figure 8 shown, an embodiment of the present utility model provides a flat heating structure of a steaming and baking module, which includes a heating tube 1 and a ceramic glass 2 arranged in sequence from top to bottom. For the convenience of description, the upper side in Figure 1 is defined as the upper, and Figure 1 the lower side in

[0059] is defined as the lower. The outer periphery of the ceramic glass 2 is provided with a support frame 3, and an annular installation groove 30 is arranged inside the support frame 3, and the side of the ceramic glass 2 is located in the installation groove 30. In this embodiment, the cross section of the installation groove 30 is U-shaped, and the opening faces the ceramic glass 2. One side of the support frame 3 is provided with a diversion plate 34 that gradually extends downward and obliquely at the end away from the ceramic glass 2, and the diversion plate 34 is provided with a plurality of heat dissipation holes 341. Above the support frame 3, guide rails 4 are arranged in parallel, and the guide rails 4 are fixedly connected to the inner side of the cooking cavity top plate of the cooking device. The top of the support frame 3 is provided with a sliding plate 5 corresponding to the guide rails 4, and the sliding plate 5 is slidably connected to the guide rails 4. Figure 23As shown in the figure, the heating tube 1 and two guide rails 4 are fixed to the inner side of the top plate of the cooking cavity (such as the inner liner) of a cooking device (such as an oven, a steam box, a steam oven, or the steam oven of an integrated stove). The ceramic glass 2 and the support frame 3 are formed into an integral component. The integral component is lifted flat so that the slide plate 5 on the support frame 3 aligns with the guide rail 4 fixed in the cooking cavity, and then it can be quickly installed successfully with a push. The ceramic glass 2 is a high-temperature resistant transparent material. The heat and light of the heating tube 1 can penetrate, radiate, and transfer to the inside of the cooking cavity, and the cooking cavity itself can also radiate the heat and light generated by the heating tube 1. As Figure 24 As shown, when the flat heating structure of the steam roasting module provided by the embodiment of the present invention is in use, the local heat inside the flat heating structure will flow from area A to area B and flow out of the internal closed area of the flat heating structure (the area between the ceramic glass 2 and the top plate of the cooking cavity) through the heat dissipation holes 341 of the flow guide plate 34; synchronously, the hot air inside the convection air hood of the cooking device flows out from area C of the convection air hood, and the hot air blown out by the convection air hood drives the hot air flowing out of the heat dissipation holes of the flat heating structure to flow to area D together; the hot air in area D will flow to area E inside the cooking cavity, and the hot air in area E will be blown out of the convection air hood again through the air duct of the fan, and so on in a cycle. The heat of the flat heating structure is concentrated and flows out from the heat dissipation holes 341 and then is blown out by the hot air, which enhances the thermal efficiency of cooking food by air frying and improves the uniformity of the temperature field in the cavity. During this process, the flow guide plate 34 extending obliquely downward can direct the hot air blown out by the lower convection air hood to area D. During this process, the flow guide plate extending obliquely downward can direct the hot air blown out by the lower convection air hood and is convenient for condensed water to flow downward along the flow guide plate. The ceramic glass 2 shields the heating tube 1 located above and the top of the cooking cavity, which can prevent oil stains and dirt after cooking from adhering to the heating tube 1 and the top of the cooking cavity, and is easy to clean. And when the cooking oil adheres to the bottom surface of the ceramic glass 2 and the support frame 3 during cooking, the support frame 3 connected to the ceramic glass 2 can be slid out together through the guide rail 4, which is convenient for disassembling and cleaning. In addition, the ceramic glass 2 shields the heating tube 1 located above and the top of the cavity, avoiding the exposure of the heating tube of the cavity, and the overall effect is more beautiful. Since the flat heating structure of the steam roasting module provided by the embodiment of the present invention is fixed to the inner side of the top plate of the cooking cavity, and the support frame 3 is provided on the outer periphery of the ceramic glass 2 for abutting against the inner wall of the cooking cavity, it can play a certain sealing role, effectively prevent steam from leaking out, and effectively prevent heat dissipation, so that the temperature rise of the components of the whole machine will not be too high, and it also avoids damaging the cooking device components above, such as the air duct, water tank, circuit board, etc.

[0060] For the convenience of installing the ceramic glass 2, as Figure 4 、 Figure 7 、 Figure 8As shown, the support frame 3 is a split type, and the support frame 3 includes two relatively arranged first fixing plates 31, and relatively arranged second fixing plates 32 and third fixing plates 33.

The first positioning portion 3121 is provided with a first positioning hole 3122. On the side of the first vertical plate 312 facing the microcrystalline glass 2, there is a first groove plate 313, and an installation groove 30 is formed between the first groove plate 313 and the first bottom plate 311. The sliding plate 5 is arranged on the top surface of the first groove plate 313. The first fixing plate 31 can be installed left and right interchangeably to reduce the number of parts.

On the side of the connecting cylinder 323 facing the microcrystalline glass 2, there is a second groove plate 324, and an installation groove 30 is formed between the second groove plate 324 and the second bottom plate 321. The first positioning hole 3122 and the connecting cylinder 323 are fixedly connected by a positioning bolt 3231.

[0063] As Figure 3 , Figure 6 , Figures 17 - 20 shown, the third fixing plate 33 includes a third bottom plate 331.

A limiting plate 314 with an inverted U-shaped cross-section is further provided on the top surface of the first base plate 311, and both ends of the top of the limiting plate 314 extend outside the first base plate 311 to form a limiting portion 3141. The limiting portion 3141 corresponds to the top of the square hole 3123 and is provided with a limiting hole 3142. As Figure 2 , Figure 5 , Figures 13 - 16 As shown in Figures 13 - 16 , both ends of the second groove plate 324 are located outside the connecting cylinder 323 to form a second positioning portion 3241. A second positioning hole 3242 is provided on the second positioning portion 3241. The second positioning portion 3241 is inserted into the corresponding square hole 3123 and is connected to the limiting portion 314 by a limiting bolt 3142.

A third positioning hole 3352 is provided on the third positioning portion 3351. The third positioning portion 3351 is inserted into the corresponding square hole 3123 and is connected to the limiting portion 314 by a limiting bolt 3142. In addition to keeping the bottom surfaces of the first fixing plate 31, the second fixing plate 32, and the third fixing plate 33 flat, the second positioning portion 3241 and the third positioning portion 3351 pass through the square hole 3123 on the first positioning portion 3121 and are fixedly connected to the limiting portion 3141 of the limiting plate 314, which can further improve the connection strength between the first fixing plate 31, the second fixing plate 32, and the third fixing plate 33 and prevent loosening.
