[0052] As Figures 1-4 shown, an embodiment of the present utility model provides a flat heating structure of a steam baking module, which includes a heating tube 1 and a microcrystalline glass 2 arranged in sequence from top to bottom. For the convenience of description, the upper side in Figure 1 is defined as up, Figure 1 and the lower side in

[0053] is defined as down. A support frame 3 is arranged on the outer periphery of the microcrystalline glass 2, and an annular installation groove 30 is arranged on the inner side of the support frame 3, and the side edge of the microcrystalline 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 microcrystalline glass 2. One side edge of the support frame 3 is provided with a diversion plate 34 that gradually extends downward and obliquely, and the diversion plate 34 is provided with a plurality of heat dissipation holes 341. Figure 21As shown, when the flat heating structure of the steam roasting module provided by the embodiment of the present utility model 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 microcrystalline 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, enhancing the thermal efficiency of cooking food by air frying and improving the uniformity of the temperature field in the cavity. During this process, the flow guide plate 34 extending obliquely downward can guide the hot air blown out by the lower convection air hood to area D, and the flow guide plate 34 adopts a structure with an inclined downward transition, which is convenient for the condensed water to flow downward along the flow guide plate 34. When the flat heating structure of the steam roasting module provided by the embodiment of the present utility model is in use, the microcrystalline glass 2 shields the heating tube 1 located above and the top of the cooking cavity, which can prevent the 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. In addition, the microcrystalline glass 2 shields the heating tube 1 located above and the cavity top, avoiding the exposure of the heating tube 1 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 utility model is fixed inside the top plate of the cooking cavity, and a support frame 3 is provided on the outer periphery of the microcrystalline glass 2 for abutting against the inner wall of the cooking cavity, it can play a certain sealing role, effectively prevent the steam from leaking out, and effectively prevent the heat from dissipating, 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.

[0054] As Figure 1 、 Figure 2 、 Figure 4 shown, in order to install the flat heating structure, a spring buckle assembly and a fixing piece are provided at the top of the support frame 3. The spring buckle assembly includes an upper buckle 4 and a lower buckle 5, which are snap-connected to each other. One side of the fixing piece 6 and the upper buckle 4 are both fixedly connected to the top plate of the cooking device cavity, and the other side of the fixing piece 6 and the lower buckle 5 are fixedly connected to the top of the support frame 3. As Figure 5 、 Figure 6 shown, in this embodiment, the fixing piece 6 is rectangular and extends obliquely downward on the outside. The inner side of the fixing piece 6 is provided with a first bolt column 61 for fixedly connecting to the top plate of the cooking device cavity, and the outer side is provided with a second bolt column 62 for fixedly connecting to the top of the support frame 3. As Figure 19 、 Figure 20As shown in the figure, when installing the flat heating structure of the steam cooking module provided by the embodiment of the present utility model, the ceramic glass 2 is installed into the installation groove 30 of the support frame 3 to form an integral assembly. Then, the heating tube 1 is fixed to the inner side of the top plate of the cooking cavity of the cooking device, the upper buckle 4 of the spring buckle assembly is fixed to the area with a relatively narrow space on the top plate of the cooking cavity, the outer side of the fixing piece 6 is fixed to the top surface of the support frame 3 (corresponding to the area with a larger space on the top plate of the cooking cavity), and finally, the support frame 3 is moved upward until the lower buckle 5 corresponds to the upper buckle 4 in a snap-fit manner. Tap it upward forcefully to make the upper buckle 4 and the lower buckle 5 snap in place, and fix the inner side of the fixing piece 6 to the top plate of the cooking cavity of the cooking device through connecting pieces such as screws and bolts. Since the volume of the spring buckle assembly is small, the flat structure heating structure of the present utility model can adapt to the narrow space at the top of the cooking device cavity and can meet the requirements of easy assembly and disassembly.

[0055] In an embodiment of the present utility model, as Figure 2 , Figure 3 , Figures 7-11 shown, the upper buckle 4 includes a first mounting plate 41 and a sleeve 42. The top of the first mounting plate 41 is fixedly connected to the top plate of the cavity of the cooking device. The sleeve 42 is provided at the bottom of the first mounting plate 41. A first annular groove 43 is provided on the inner wall of the sleeve 42, and an S-shaped spring 44 is provided in the first annular groove 43, so that a part of the spring 44 protrudes from the first annular groove 43 to form a limiting portion 441. The lower buckle 5 includes a second mounting plate 51 and a plug 52. The second mounting plate 51 is fixedly connected to the top of the support frame 3. The plug 52 is provided at the top of the second mounting plate 51, and a second annular groove 53 is provided on the outer wall of the plug 52. The limiting portion 441 is normally kept in the second annular groove 53. During installation, the support frame 3 is pushed upward, and the plug 52 of the lower buckle 5 is inserted into the sleeve 42 of the upper buckle 4. The limiting portion 441 of the spring 44 in the sleeve 42 is first forced to retract into the first annular groove 43. When the second annular groove 53 of the plug 52 corresponds to the first annular groove 43, the limiting portion 441 of the spring 44 rebounds and snaps into the second annular groove 53, and the spring 44 and the plug 52 are in interference fit, which can hold the lower buckle 5 and limit the up and down movement of the lower buckle 5, thus completing the installation of the entire flat heating structure. Preferably, the number of the limiting portions 441 is multiple and they are evenly distributed along the circumferential direction of the first annular groove 43 to provide a good positioning effect for the plug 52.

[0056] As Figure 9 , Figure 10 shown, in an embodiment of the present utility model, opposite vertical grooves 45 are provided on the inner wall of the sleeve 42, and the vertical grooves 45 extend upward from the bottom end of the sleeve 42 to the first annular groove 43. The vertical grooves 45 are used to facilitate the tip of the pliers to grip the wire diameter of the spring 44 during the process of disassembling and assembling the spring 44.

[0057] AsFigure 2 , Figures 7-10 As shown in Figures 7-10 , in an embodiment of the present utility model, the first mounting plate 41 is provided with fixing columns 46 extending downward, and is fixedly connected to the top plate of the cooking device cavity through bolts or screws inside the fixing columns 46.

[0058] As Figure 11 shown, in an embodiment of the present utility model, the top of the plug 52 is successively provided with a first transition surface 521 and a second transition surface 522 from top to bottom. The first transition surface 521 gradually extends downward from inside to outside, and the second transition surface 522 gradually extends downward from outside to inside and is connected to the top of the second annular groove 53. The first transition surface 521 facilitates reducing the resistance between the spring 44 and the plug 52 when the plug 52 of the lower buckle 5 is inserted upward into the sleeve 42 of the upper buckle 4, and the second transition surface 522 facilitates reducing the resistance between the spring 44 and the plug 52 when the plug 52 of the lower buckle 5 is pulled out downward from the sleeve 42 of the upper buckle 4.

[0059] To facilitate the installation of the ceramic glass 2, as Figures 1-4 shown, the support frame 3 is a split type, which includes two oppositely arranged first fixing plates 31 and two oppositely arranged second fixing plates 32. The outside of the flow guide plate 34 is fixedly arranged outside one of the second fixing plates 32. The top of the first fixing plate 31 is provided with a vertical third mounting plate 33. The top surface of the second mounting plate 51 is provided with a mounting portion 54 extending upward, and the mounting portion 54 is fixedly connected to the side surface of the third mounting plate 33. The mounting portion 54 and the side surface of the third mounting plate 33 can be fixedly connected by bolts or screws, and corresponding through holes are provided on the mounting portion 54 and the third mounting plate 33 at this time.

[0060] Specifically, as Figures 12-13 shown, the first fixing plate 31 includes a first bottom plate 311. The top surface of the first bottom plate 311 is provided with a first groove plate 312 with an inverted L-shaped cross-section, and both ends of the first groove plate 312 extend outside the first bottom plate 311.

In the middle of the vertical plate 322, there is a second groove plate 323 extending towards the direction of the microcrystalline glass. An installation groove 30 is formed between the second groove plate 323 and the second bottom plate 321. Above the second groove plate 323, there is a connecting column 324, and the connecting column 324 and the connecting hole 331 are fixedly connected by bolts or screws. When the flat heating structure of the steam baking module provided in this embodiment is installed, a pair of opposite sides of the microcrystalline glass 2 can be installed into the installation grooves 30 of the two first fixing plates 31, and then the other pair of opposite sides of the microcrystalline glass 2 can be installed into the installation grooves 30 of the two second fixing plates 32. The connecting holes 331 at both ends of the first fixing plate 31 and the connecting columns 324 of the two second fixing plates 32 are detachably connected by means of screws or bolts, etc., to form an integral assembly.

The third groove plate 313 is located outside the first groove plate 312, that is, on the side away from the microcrystalline glass 2. The positioning portion 3131 overlaps with the end of the second groove plate 323 and is fixedly connected to the second groove plate 323 by a positioning bolt 7. The second groove plate 323 is provided with a notch portion to avoid the end of the first groove plate 312 when the first fixing plate 31 and the second fixing plate 32 are connected. In addition to enabling the bottom surfaces of the first fixing plate 31 and the second fixing plate 32 to remain flat in a slightly deformed state, the connection between the positioning portion 3131 and the second groove plate 323 by the positioning bolt 7 can further improve the connection strength between the first fixing plate 31 and the second fixing plate 32 on the basis of the connecting column 324 and the connecting hole 331, and prevent loosening between the two.
