[0040] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides a flat heating structure of a steaming and baking module, including a reflector 1, a heating tube 2 and a microcrystalline glass 3 arranged in sequence from top to bottom. For the convenience of description, the following definitions Figure 3 and Figure 7 The upper part in the above is the upper part, Figure 1 The lower part in the figure is below.

[0041] like Figure 3 , Figure 4 As shown, the reflector 1 includes an outer cover plate 11 and an inner cover plate 12. The inner cover plate 12 is arranged at the bottom of the outer cover plate 11 and is sealed and connected to the outer cover plate 11 and evacuated to form a vacuum insulation space 13. The heating tube 2 is connected to the bottom of the outer cover plate 11 or the inner cover plate 12 through a bracket 4. The microcrystalline glass 3 is a high temperature resistant transparent material. The heat and light of the heating tube 2 can penetrate the microcrystalline glass 3 and radiate and transfer to the inside of the cooking cavity of the cooking device.

[0042] When installing the flat heating structure of the steaming and baking module provided by the embodiment of the utility model, the microcrystalline glass 3 is fixed to the top of the cooking cavity (e.g., inner pot) of the cooking device (e.g., oven, steamer, steam oven, steam oven of integrated stove) by gluing (e.g., high temperature resistant silicone) or the like. Then the reflector 1 with the heating tube 2 installed is fixedly connected to the top of the cooking cavity of the cooking device by screws or other fixing methods to complete the installation of the entire flat heating structure. The entire flat heating structure can be installed on the top of the cooking cavity, or it can be opened at the top of the cooking cavity, and the microcrystalline glass 3 and the reflector 1 are fixed to the outside of the opening at the top of the cooking cavity to avoid occupying the space of the cooking cavity. When the flat heating structure of the steaming and baking module provided by the embodiment of the utility model is in use, the microcrystalline glass 3 blocks the heating tube 2 located above and the top of the cavity, which can prevent the oil stains and stains after cooking from adhering to the heating tube 2 and the top of the cavity, and is easy to clean. In addition, the microcrystalline glass 3 blocks the heating tube 2 located above and the top of the cavity to prevent the heating tube 2 of the cavity from being exposed, and the overall effect is more beautiful. The reflective cover 1 of the flat heating structure of the steaming and baking module provided in the embodiment of the utility model can isolate the heat of the heating tube 2 upwards through the vacuum insulation space 13 formed by the outer cover plate 11 and the inner cover plate 12, ensuring that the heat is transferred downwards as much as possible and reflected into the cooking cavity of the cooking equipment below, avoiding energy loss and damage to the cooking equipment components above, such as air ducts, water tanks, circuit boards, etc.

[0043] In one embodiment of the present invention, Figure 1-Figure 3 As shown, in order to further improve the reflection effect of the reflector 1 on heat and light, the side of the outer cover plate 11 extends downward to be provided with a first folded edge 111, forming a cylinder with an opening downward, which can reflect the light and heat of the heating tube 2 to the bottom, thereby reducing energy loss. Further, one group of opposite first folded edges 111 is provided with a plurality of first mounting grooves 112 arranged at intervals, and the heating tube 2 is penetrated in two opposite first mounting grooves 112. Each first mounting groove 112 separates the first folded edge 111 into a plurality of second folded edges 113, and the bottom end of the second folded edge 113 is used to connect with the cooking cavity of the cooking device. For example, a first mounting folded edge 114 can be provided at the bottom end of the second folded edge 113, and the first mounting folded edge 114 is connected to the edge of the cooking cavity of the cooking device by screws. The first folded edge 111 can not only improve the reflection effect of the reflector 1 on heat and light, but also provide a fixed connection point between the reflector 1 and the cooking cavity of the cooking device.

[0044] In one embodiment of the present invention, Figure 1-Figure 3As shown, a first mounting plate 115 is horizontally extended outward from the top of the first mounting groove 112, and the bracket 4 is arranged on the bottom surface of the first mounting plate 115. In this embodiment, the first mounting groove 112 and the first mounting plate 115 can be formed simultaneously by stamping through a plate material for installing the heating pipe 2, which saves working procedures, reduces manufacturing costs, and improves production efficiency.

[0045] like Figure 5-Figure 9 As shown, in another embodiment of the utility model, in order to further improve the efficiency of the reflector 1 in reflecting light and heat, the inner cover plate 12 is provided with a groove 121 corresponding to the heating tube 2, and the cross-section of the groove 121 is an upwardly convex arc shape, which realizes the function of energy gathering and heat reflection. The heating tube 2 is completely or partially located in the groove 121, so that the heating tube 2 reflects light and heat vertically downward to reduce energy dissipation.

[0046] like Figure 6 , Figure 7 , Fig. 9 As shown, in order to further improve the reflection effect of the reflector 1 on heat and light, the side of the inner cover plate 12 is extended downward to form a third folded edge 122, forming a cylinder with an opening downward, which can reflect the light and heat of the heating tube 2 to the bottom, thereby reducing energy loss. One group of opposite third folded edges 122 is provided with a plurality of second mounting grooves 123 arranged at intervals, and the heating tube 2 is penetrated in two opposite second mounting grooves 123. Each second mounting groove 123 divides the third folded edge 122 into a plurality of fourth folded edges 124. The bottom end of the fourth folded edge 124 is used to connect with the cooking cavity of the cooking device. For example, a second mounting folded edge 125 can be provided at the bottom end of the fourth folded edge 124, and the second mounting folded edge 125 is connected to the edge of the cooking cavity of the cooking device by screws. The third folded edge 122 can not only improve the reflection effect of the reflector 1 on heat and light, but also provide a fixed connection point between the reflector 1 and the cooking cavity of the cooking device.

[0047] Further, in order to realize that a sheet metal can be used to make the entire inner cover plate 12, such as Fig. 9 As shown, the inner side of the third folded edge 122 has a transition groove 126, and the cross section of the transition groove 126 is a circular arc shape that is concave downward. In this embodiment, the inner cover plate 12 is provided with a transition groove 126, connecting the groove 121 part and the third folded edge 122 part. The transition groove 126 is a curved surface transition, and a deep drawing process is adopted, so that the curved surface of the reflector 1 can be naturally transitioned.

[0048] like Figure 6 , Figure 7As shown, in one embodiment of the utility model, a second mounting plate 127 is horizontally extended outward from the top of the second mounting groove 123, and the bracket 4 is arranged on the bottom surface of the second mounting plate 127. In this embodiment, the second mounting groove 123 and the second mounting plate 127 can be formed by stamping at the same time through a plate material for installing the heating pipe 2, which saves working procedures, reduces manufacturing costs, and improves production efficiency.

[0049] In one embodiment of the present invention, the heating tube 2 is a glass tube. In order to solve the problem that the existing fixing method of the glass heating tube 2 is prone to breakage, Figure 3 , Figure 7 As shown, ceramic beads 21 are provided at both ends of the glass tube 2 , and the ceramic beads 21 are fixedly connected to the bottom end of the bracket 4 .

[0050] In order to further protect the glass heating tube 2, Fig.10 As shown, in a preferred embodiment of the utility model, the bracket 4 includes a fixing plate 41, which is provided with a fixing hole 411 and is fixed to a fixing plane corresponding to the reflector 1 (for example, the first mounting plate 115 or the second mounting plate 127). Both ends of the fixing plate 41 are provided with a clamping plate 42 extending downward, and the middle part of the clamping plate 42 protrudes outward to form a clamping portion 421, and the cross-section of the clamping portion 421 is arc-shaped. The ceramic bead 21 is located between the two clamping portions 421. By utilizing the elasticity of the clamping plate 42, the ceramic bead 21 can be clamped while adapting to a certain amount of displacement and deformation of the ceramic bead 21, giving the glass heating tube 2 a buffer, and ensuring that external vibrations do not affect the fragile glass heating tube 2. At the same time, by fixing the heating tube 2 with a buckle of the flexible bracket 4, the equipment transportation process can be made more reliable and the glass heating tube 2 is not easily damaged. In order to facilitate the installation of the heating tube 2, the bottom end of the clamping plate 42 is provided with a guide portion 422 extending outward, and the two guide portions 422 form a trumpet-shaped opening. The ceramic beads 21 at both ends of the heating tube 2 are pushed into between the two clamping portions 421 along the opening. When the ceramic beads 21 of the heating tube 2 enter the clamping portion 421, the clamping portion 421 can be opened to both sides. After the ceramic beads 21 completely enter between the two clamping portions 421, the clamping portion 421 is retracted under the action of elastic deformation, and the ceramic beads 21 are clamped to complete the installation, thereby improving the installation efficiency of the heating tube 2. The ribs formed between the fixing plate 41 and the top of the clamping plate 42 and the ribs formed between the clamping plate 42 and the top of the clamping portion 421 improve the upper rigidity of the flexible bracket 4. The ribs formed between the clamping plate 42 and the bottom of the clamping portion 421 improve the lower rigidity of the flexible bracket 4 and can clamp the ceramic beads 21 of the heating tube 2.

[0051] In order to further improve the efficiency of the reflector 1 in reflecting light and heat, the bottom surface of the inner cover plate 12 is provided with a reflective heat-insulating coating, such as a bright surface or a frosted surface, which has a mirror reflection and diffuse reflection effect on the heat energy and light emitted by the heating tube 2.

[0052] The utility model also provides a cooking device, including the flat heating structure of the steaming and baking module. Fig.11 , Fig.12 As shown, the cooking device is provided with a cooking cavity 5 for heating food, the micro-ceramic glass 3 is fixedly arranged on the top of the cooking cavity 5, and the reflector 1 is located above the micro-ceramic glass 3 and is fixedly connected to the top of the cooking cavity 5. The cooking device is a device having a cooking cavity 5 (such as an inner pot), such as an oven, a steamer, a steam oven, an integrated stove, etc. The entire flat heating structure can be installed at the top of the cooking cavity 5, or the top of the cooking cavity 5 can be opened, and the micro-ceramic glass 3 and the reflector 1 are fixed outside the top opening of the cooking cavity 5 to avoid occupying the space of the cooking cavity.

[0053] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
