[0054] As Figures 1 - 4 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 part in Figure 1 is defined as the upper, Figure 1 and the lower part in

[0055] 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.

[0056] When the flat heating structure of the steaming and baking module provided by the embodiment of the present utility model is installed, as Figure 19 , Figure 20As shown in the figure, the glass-ceramics 2 is installed in the installation groove 30 of the support frame 3 to form an integral assembly. Then, the heating tube 1 and the upper buckle 4 of the spring buckle assembly (through connecting parts such as screws and bolts) are fixed to the inner side of the top plate of the cooking cavity (such as the inner liner) of the cooking device (such as an oven, a steam box, a steam oven, or the steam oven of an integrated stove). Finally, the support frame 3 is moved upward until the lower buckle 5 corresponds to the upper buckle 4, and a hard pat upward can complete the installation. Since only the support frame 3 needs to be pushed upward during installation and the spring buckle assembly is small in volume, the flat 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. The glass-ceramics 2 is a high-temperature resistant transparent material, and the heat and light of the heating tube 1 can penetrate, radiate, and transfer to the inside of the cooking cavity. The flat heating structure of the present utility model is fixed to the inner side of the top of the cooking cavity. The cooking cavity itself can radiate the heat and light generated by the heating tube 1. Synchronously, the heat and light of the heating tube 1 penetrate the glass-ceramics 2 and radiate into the cooking cavity. When the flat heating structure of the steam roasting module provided by the embodiment of the present utility model is in use, the glass-ceramics 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. In addition, the glass-ceramics 2 shields the heating tube 1 located above and the top of the cavity, 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 to the inner side of the top plate of the cooking cavity and the outer periphery of the glass-ceramics 2 is provided with a support frame 3 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.

[0057] In one embodiment of the present utility model, as Figure 2 、 Figures 7 - 11As 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 cavity top plate 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 positioning 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 positioning portion 441 is normally held 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 positioning 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 positioning portion 441 of the spring 44 rebounds and is snapped 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 restrict 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 positioning 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.

[0058] As Figure 9 、 Figure 10 shown, in an embodiment of the present invention, 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 clamp the wire diameter of the spring 44 during the process of disassembling and assembling the spring 44.

[0059] As Figure 2 、 Figures 7 - 10 shown, in an embodiment of the present invention, the first mounting plate 41 is provided with a fixing post 46 extending downward, and is fixedly connected to the top plate of the cooking device cavity through bolts or screws in the fixing post 46.

[0060] As Figure 11 shown, in an embodiment of the present invention, the top of the plug 52 is sequentially 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.

[0061] For the convenience of installing the glass-ceramics 2, as Figures 1 - 3 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. A vertical third mounting plate 33 is provided on the top of the first fixing plate 31. An upwardly extending mounting portion 54 is provided on the top surface of the second mounting plate 51, 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. At this time, corresponding through holes are provided on the mounting portion 54 and the third mounting plate 33.

[0062] Specifically, as Figures 12 - 14 shown, the first fixing plate 31 includes a first bottom plate 311. A first groove plate 312 with an inverted L-shaped cross section is provided on the top surface of the first bottom plate 311, and both ends of the first groove plate 312 extend outside the first bottom plate 311. An installation groove 30 is formed between the first groove plate 312 and the first bottom plate 312. The third mounting plate 33 is provided on the top surface of the first groove plate 312, and connection holes 331 are provided at both ends of the third mounting plate 33. As Figures 15 - 18 shown, the second fixing plate 32 includes a second bottom plate 321. A vertical plate 322 is provided on the top surface of the second bottom plate 321. A second groove plate 323 extending towards the glass-ceramics is provided in the middle of the vertical plate 322. An installation groove 30 is formed between the second groove plate 323 and the second bottom plate 321. A connection column 324 is provided above the second groove plate 323, and the connection column 324 is fixedly connected to the connection hole 331 by bolts or screws. When the flat heating structure of the steam cooking module provided in this embodiment is installed, a pair of opposite sides of the glass-ceramics 2 can be installed in the installation grooves 30 of the two first fixing plates 31, and then the other pair of opposite sides of the glass-ceramics 2 can be installed in the installation grooves 30 of the two second fixing plates 32. The connection holes 331 at both ends of the first fixing plate 31 and the connection columns 324 of the two second fixing plates 32 are detachably connected by screws or bolts and the like to form an integral assembly. Then, the heating tube 1 and the upper buckle 4 of the spring buckle assembly (through connecting pieces such as screws and bolts) are fixed to the inner side of the top plate (i.e., the bottom surface of the top plate) of the cooking cavity (such as the inner liner) of the cooking device (such as an oven, a steamer, a steam oven, or the steam oven of an integrated stove). Finally, the support frame 3 is moved upward until the lower buckle 5 is snap-connected to the upper buckle 4, and the installation can be completed.

[0063] After the first fixing plate 31 and the second fixing plate 32 are fixedly connected, the plate surfaces of the first bottom plate 311 and the second bottom plate 321 may be uneven, affecting the appearance effect. Therefore, in a preferred embodiment of the present invention, in order to avoid the situation that the bottom surfaces of the first fixing plate 31 and the second fixing plate 32 are uneven, as Figures 12 - 18As shown, two mutually parallel first rib plates 313 are provided on the outer side of the top surface of the first bottom plate 311, and a first positioning plate 314 extending towards the other first rib plate 313 is provided at the top end of the first rib plate 313. At both inner ends of the top surface of the second bottom plate 321, two mutually parallel second rib plates 325 are provided respectively, and a second positioning plate 326 extending towards the other second rib plate 325 is provided at the top end of the second rib plate 325. Refer to Figures 2 - 6 , a fixing piece 6 is provided between the first rib plate 313 and the second rib plate 325. The fixing piece 6 is in an L shape and includes a first piece 61 and a second piece 62 which are perpendicularly connected to each other. First screw holes 63 are provided on both the first piece 61 and the second piece 62, and the first piece 61 and the second piece 62 are respectively located between the two first rib plates 313 and between the two second rib plates 325. Positioning bolts 7 are provided between the two first positioning plates 314 and between the two second positioning plates 326. The end of the positioning bolt 7 abuts against the top surfaces of the first positioning plate 314 and the second positioning plate 326, and the threaded end of the positioning bolt 7 is connected to the corresponding first screw holes 63 on the first piece 61 and the second piece 62. After the positioning bolt 7 is rotated in place, the top surfaces of the first piece 61 and the second piece 62 respectively abut against the bottom surfaces of the first positioning plate 314 and the second positioning plate 326. The positioning bolt 7 passes through the first screw hole 63 of the fixing piece 6 and directly abuts against the planes of the first bottom plate 311 and the second bottom plate 321. Since both the positioning bolt 7 and the first screw hole 63 of the fixing piece 6 have threads, when the positioning bolt 7 moves downward to abut against the first bottom plate 311 and the second bottom plate 321, the fixing piece 6 moves upward and abuts against the bottom surfaces of the first positioning plate 314 and the second positioning plate 326. After the positioning bolt 7 is in place, the first positioning plate 314 and the second positioning plate 326 are subjected to upward and downward pressing forces, so that the cooperation of the first positioning plate 314 and the second positioning plate 326 is flattened, and further the bottom surface of the connection part between the first fixing plate 31 and the second fixing plate 32 is flattened. Further, a second screw hole 64 corresponding to the first screw hole 63 is provided on the first bottom plate 311 or the second bottom plate 321. In this embodiment, the second screw hole 64 is provided on the first bottom plate 311. The bottom end of the positioning bolt 7 is located in the second screw hole 64, which 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.

[0064] As Figure 2 , Figure 15 , Figure 16 shown, in order to facilitate the installation and positioning of the fixing piece 6, an outer end of one of the two second rib plates 325 close to the microcrystalline glass 2 has a notch for the fixing piece 6 to be arranged.

[0065] As Figure 1 ,Figure 3 , Figure 4 , Figure 6 , Figure 18 As shown in Figure 3 , Figure 4 , Figure 6 , and Figure 18 , in an embodiment of the present utility model, among the two second fixing plates 32, one end of the second bottom plate 321 of one second fixing plate 32 away from the glass-ceramics 2 is provided with a diversion plate 34 extending gradually downward and obliquely. The diversion plate 34 adopts a structure with an inclined downward transition, which is convenient for the condensed water to flow downward along the diversion plate 34. Further, a plurality of heat dissipation holes 341 are provided on the diversion plate 34. The design of the heat dissipation holes 341 enables the heat between the heating tube 1 and the glass-ceramics 2 to flow out through the heat dissipation holes 341, reducing the temperature rise of the entire flat heating structure and improving the thermal efficiency inside the cooking cavity of the cooking device. In order to improve the structural strength of the diversion plate 34, a plurality of reinforcing ribs 342 are provided on the top surface of the diversion plate 34.

[0066] As Figure 1 , Figure 3 shown in Figure 1 and Figure 3 , in an embodiment of the present utility model, the vertical plate 322 and the connecting column 324 of the second fixing plate 32 are provided with notches corresponding to the heating tube 1, and the heating tube 1 passes through the notches. Further, a plurality of ends of the heating tube 1 are arranged on an integrated board 8, and the integrated board 8 is located outside the second fixing plate 32.

[0067] In an embodiment of the present utility model, the support frame 3 is made of aluminum profile. The advantages of using an aluminum profile structure are: (1) fast heat transfer speed; (2) simple structure and easy assembly; (3) beautiful appearance and high cost performance.
