[0053] A cooking appliance generally includes a cooking surface and a pot support provided on the cooking surface. The top of the pot support has an upper support for supporting a workpiece to be heated (such as a cooking utensil). In a product where the pot support is composed of an upper plate and a lower plate spliced together, the upper support is usually used to realize the installation and fixation of the upper plate and the lower plate.

[0054] Specifically, the upper support is pre-fixed on the upper plate, and the lower end of the upper support extends into the cavity between the upper plate and the lower plate. An installation groove for embedding the nut is provided at the lower end of the upper support, and the lower plate is provided with an installation through-hole corresponding to the nut. During assembly, the nut needs to be embedded in the installation groove first, and then one end of the bolt is passed through the installation through-hole and extends into the cavity after the upper and lower plates are aligned and fastened, so that the bolt can be locked on the nut, thereby realizing the installation and fixation of the upper plate and the lower plate. This installation method is not convenient enough, resulting in low production and assembly efficiency of the pot support.

[0055] In view of this, the present utility model proposes a pot support.

[0056] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, the pot support includes:

[0057] A first support 10, the first support 10 includes a separately provided upper plate 11 and a lower plate 12, and a cavity 10a is formed between the upper plate 11 and the lower plate 12; and

[0058] A support structure 20, provided in the cavity 10a and used for connecting the upper plate 11 and the lower plate 12.

[0059] The technical solution of the present utility model realizes the installation and fixation of the upper plate and the lower plate through the support structure provided in the cavity 10a, without requiring the upper plate to be provided with an insertion hole, thereby being able to avoid the problem of weakening the structural strength of the upper plate and enhancing the structural strength of the upper plate.

[0060] Further, the support structure includes an installation portion 20b and two fixing portions 20a connected to both ends of the installation portion 20b. One of the upper plate 11 and the lower plate 12 is connected to the installation portion 20b, and the other is connected to the two fixing portions 20a. Specifically, optionally, the installation portion 20b is correspondingly connected to the middle of the lower plate 12, and the two fixing portions 20a are respectively correspondingly connected to the outer edge and the inner edge of the upper plate 11. In this way, the installation portion 20b and the two fixing portions 20a form a relatively stable triangular structure, making the installation and fixation relationship between the upper plate and the lower plate more stable and reliable.

[0061] Optionally, one of the upper plate 11 and the lower plate 12 is fixed with the support structure 20, and the other is installed on the support structure 20 through a first fastener 61. In this way, by pre-fixing the support structure 20 on the upper plate 11, during assembly, only the upper plate 11 and the lower plate 12 need to be aligned, and the support structure 20 is connected by using the first fastener 61, so as to realize the installation and fixation of the upper plate 11 and the lower plate 12. Compared with the prior art, the technical solution of the present utility model can save the process of embedding the nut in the installation groove of the upper support 50, thereby simplifying the assembly process of the upper plate 11 and the lower plate 12 and improving the production and assembly efficiency of the pot support 101.

[0062] Without loss of generality, the pot support 101 is usually provided on the liquid receiving tray of the cooking appliance and is used for supporting a heating object, such as a cooking utensil (including but not limited to a flat pan, a pointed pan, etc.). The first support 10 defines a central hole 102. The central hole 102 is usually used to house the burner of the cooking appliance and to enable the flame formed by the burner to act on the bottom surface of the cooking utensil.

[0063] Please refer to Figure 7 and Figure 13 , optionally, a plurality of support structures 20 are provided. The plurality of support structures 20 are spaced apart along the circumferential direction of the central hole 102. In this way, the installation reliability of the upper plate 11 and the lower plate 12 can be improved, and the weight and manufacturing cost of the pot support 101 will not be significantly increased. Of course, in other embodiments, only one support structure 20 may be provided.

[0064] Optionally, the fixing portion 20a is fixedly welded to the upper plate 11, and the mounting portion 20b is connected to the lower plate 12 by a first fastening member 61. In this way, the structure is simple and easy to implement, and the assembly production is more convenient. Of course, in other embodiments, the fixing portion 20a and the mounting portion 20b may both be fixed by welding, or the fixing portion 20a and the mounting portion 20b may both be fixed by fastening members such as screws or rivets; or the fixing portion 20a and the upper plate may be fixed by a fastening member, and the mounting portion 20b is fixedly welded to the lower plate.

[0065] Please refer to Figure 5 and Figure 8 , optionally, the fixing portion 20a is fixedly welded to the inner wall surface of the upper plate 11, and the first fastening member 61 passes through the lower plate 12 and is installed in the mounting portion 20b. That is, the support structure 20 is pre-fixed to the upper plate 11 by welding. The structure is simple and easy to manufacture, which not only ensures sufficient connection strength between the support structure 20 and the upper plate 11, but also improves the production efficiency of the pot support 101.

[0066] Of course, the installation method of the support structure 20 is not limited to this. For example, in some other embodiments, the support structure 20 may be pre-fixed to the lower plate 12 first, and then the upper plate 11 is assembled to the support structure 20 by using the first fastening member 61. In other embodiments, other installation methods may also be adopted to install the support structure 20, the upper plate 11 and the lower plate 12. For example, the support structure 20, the upper plate 11 and the lower plate 12 are all fixed by welding.

[0067] Please refer to Figure 5 , Figure 8 and Figure 9, optionally, the support structure 20 includes a support plate 22 and an outer limiting flange 221 bent downward from the outer edge of the support plate 22. The mounting portion 20b is formed on the support plate 22, and the fixing portion 20a includes the outer limiting flange 221. The upper plate 11 includes an upper plate 111 and an upper outer flange 112 bent downward from the outer peripheral edge of the upper plate 111. The upper outer flange 112 is fixed to the outer limiting flange 221 (such as by welding or riveting). In this way, the welding marks generated during welding can be restricted to the area of the upper plate 11 corresponding to the outer limiting flange 221, that is, the welding marks are restricted to the upper outer flange 112. Since the upper outer flange 112 belongs to the non-highly visible area of the first bracket 10, the welding marks are not easily noticed, thus improving the aesthetics of the first bracket 10.

[0068] It should be noted that the highly visible area of the pot bracket 101 refers to its visual area from a top-down perspective. Correspondingly, the remaining areas outside the highly visible area are non-highly visible areas.

[0069] Of course, in some other embodiments, the outer limiting flange 221 can also be provided on the upper plate 11 by bonding or only abutting against the upper plate 11. In other embodiments, the support plate 22 and the upper plate 11 can also be fixed by welding.

[0070] Please refer to Figure 5 and Figure 8 , optionally, the support structure 20 further includes an inner limiting flange 222 bent downward from the inner edge of the support plate 22. The fixing portion 20a further includes the inner limiting flange 222. The upper plate 11 further includes an upper inner flange 113 bent downward from the inner peripheral edge of the upper plate 111. The upper inner flange 113 is fixed to the inner limiting flange 222 (such as by welding or riveting).

[0071] In this way, on the one hand, the fixing portion 20a includes both the outer limiting flange 221 and the inner limiting flange 222, which can improve the connection strength between the upper plate 11 and the support structure 20. On the other hand, the welding marks generated during welding can be restricted to the area of the upper plate 11 corresponding to the inner limiting flange 222, that is, the welding marks are restricted to the upper inner flange 113. Since the upper inner flange 113 also belongs to the non-highly visible area of the first bracket 10, the welding marks are not easily noticed, thus improving the aesthetics of the first bracket 10.

[0072] Of course, in other embodiments, the inner limiting flange 222 and the upper inner flange 113 can also be not provided.

[0073] To improve the installation stability of the upper plate 11, please refer to Figure 5 and Figure 8, in an embodiment where the support structure 20 includes a support plate 22 and a fixing portion 20a provided at the outer edge of the support plate 22, optionally, the support plate 22 includes a first plate segment 22a, a second plate segment 22b, and a third plate segment 22c connecting the first plate segment 22a and the second plate segment 22b. The mounting portion 20b is provided on the first plate segment 22a. The plate surfaces of the first plate segment 22a and the second plate segment 22b are arranged in parallel, and the second plate segment 22b abuts against the lower surface of the upper plate 11. In this way, by the second plate segment 22b abutting against the upper plate 11, the contact area between the support structure 20 and the upper plate 11 can be increased, and the mounting stability of the upper plate 11 can be improved.

[0074] Optionally, the first bracket 10 defines a central hole 102. The support plate 22 further includes a fourth plate segment 22d and a fifth plate segment 22e connecting between the fourth plate segment 22d and the first plate segment 22a. The fourth plate segment 22d is provided on one side of the first plate segment 22a close to the central hole 102, and the second plate segment 22b is provided on the other side of the first plate segment 22a away from the central hole 102. The fourth plate segment 22d abuts against the lower surface of the upper plate 11. In this way, the fourth plate segment 22d and the second plate segment 22b jointly abut against the upper plate 11, which can further increase the contact area between the support structure 20 and the upper plate 11 and improve the mounting stability of the upper plate 11.

[0075] Please refer to Figure 5 and Figure 8 , optionally, in the direction away from the central hole 102, the third plate segment 22c extends obliquely towards the second plate segment 22b, and a part of the third plate segment 22c abuts against the lower surface of the upper plate 11. In this way, on the one hand, the third plate segment 22c also abuts against the upper plate 11, which can further increase the contact area between the support structure 20 and the upper plate 11; on the other hand, it also acts together with the outer limiting flange 221 to limit the displacement of the upper plate 11 in the radial direction of the central hole 102, thereby further improving the mounting stability of the upper plate 11.

[0076] Of course, the structural form of the support plate 22 is not limited to this, as long as it can meet the function of assembling the upper plate 11 and the lower plate 12 into one body, and the present application does not make specific limitations on this.

[0077] Please refer to Figure 2 , optionally, the upper plate 11 and the lower plate 12 have an annular gap 10b at the relative positions of the outer periphery and the inner periphery, that is, annular gaps 10b are provided at both the outer periphery and the inner periphery of the first bracket 10, so that the upper plate 11 and the lower plate 12 are in a completely separated state to avoid the occurrence of heat conduction problems between the upper plate 11 and the lower plate 12. Of course, in other embodiments, it may also be that only the upper plate 11 and the lower plate 12 have an annular gap 10b at the relative positions of the outer periphery, or only the upper plate 11 and the lower plate 12 have an annular gap 10b at the relative positions of the inner periphery.

[0078] Optionally, the width range of the annular gap 10b is configured to be from 0.5 mm to 1.5 mm. Optionally, in this embodiment, the width range of the annular gap 10b is configured to be from 0.8 mm to 1 mm. It can be understood that if the width of the annular gap 10b is too large, on the one hand, the outer contour size and volume of the first bracket 10 will be relatively large, which is not conducive to the miniaturization design of the pot bracket 101; on the other hand, the relatively wide annular gap 10b is likely to accumulate dirt and is not conducive to the first bracket 10 maintaining good hygiene. If the width of the annular gap 10b is too small, on the one hand, the heat of the upper plate 11 will be more easily transferred to the lower plate 12, that is, the heat insulation effect of the annular gap 10b is not obvious; on the other hand, the width of the limiting portion 21 will be too small (the thickness is too thin), which is not conducive to the structural strength of the limiting portion 21.

[0079] Specifically, the annular gap 10b includes an outer ring gap 10c located at the outer peripheral edge of the first bracket 10 and an inner ring gap 10d located at the inner peripheral edge of the first bracket 10. The outer limiting flange 221 is provided in the outer ring gap 10c, and the inner limiting flange 222 is provided in the inner ring gap 10d. In this way, the outer limiting flange 221 and the inner limiting flange 222 can maintain the stability of the annular gap 10b and avoid the problem of functional failure of the annular gap 10b. That is, even if the upper plate 11 and the lower plate 12 have a relative offset and cause a change trend of the annular gap 10b, the outer limiting flange 221 and the inner limiting flange 222 can block between the upper plate 11 and the lower plate 12, keep the two having the annular gap 10b, and avoid the situation of large-area direct contact, thereby facilitating the heat to stay in the upper plate 11 as much as possible.

[0080] Please refer to Figure 2 and Figure 10 , optionally, the lower plate 12 includes a lower plate 121, a lower outer flange 122 bent upward from the outer peripheral edge of the lower plate 121, and a lower inner flange 123 bent upward from the inner peripheral edge of the lower plate 121. The lower outer flange 122 is located on the side of the upper outer flange 112 close to the central hole 102 and is disposed opposite to the upper outer flange 112 to form an outer ring gap 10c at intervals; the lower inner flange 123 is located on the side of the upper inner flange 113 away from the central hole 102 and is disposed opposite to the upper inner flange 113 to form an inner ring gap 10d at intervals. In this way, the structure is simple and easy to implement. Of course, in other embodiments, the lower outer flange 122 and the lower inner flange 123 may not be provided, and the plate surfaces of the upper plate 111 and the lower plate 121 form an annular gap 10b at intervals in the up and down directions.

[0081] Of course, in some other embodiments, the inner ring gap 10d is located on the side where the outer wall surface of the upper inner flanging 113 is located, and the outer ring gap 10c is located on the side where the outer wall surface of the upper outer flanging 112 is located. In other embodiments, the upper outer flanging 112 and the upper inner flanging 113 may not be provided, and an annular gap 10b is formed by spacing between the plate surface of the upper disc plate 111 and the side edge of the lower disc 12 in the up and down directions.

[0082] Optionally, the materials of the upper disc 11, the lower disc 12, and the support structure 20 are all configured as metals and are formed by stamping processes. In this way, it is beneficial to the production and manufacturing of the pot support 101 and cost control. Of course, in other embodiments, other materials and processes may also be used to realize the production and manufacturing of the upper disc 11, the lower disc 12, and the support structure 20.

[0083] Optionally, the inner limiting flanging 222 is in clearance fit with the lower inner flanging 123, and the outer limiting flanging 221 is also in clearance fit with the lower outer flanging 122. For example, in an embodiment where the annular gap 10b is configured to be 1 mm, and the material thicknesses of the outer limiting flanging 221 and the inner limiting flanging 222 are configured to be 0.8 mm, the clearance widths between the inner limiting flanging 222 and the lower inner flanging 123, and between the outer limiting flanging 221 and the lower outer flanging 122 are both 0.2 mm. In this way, it can not only avoid the obvious heat conduction phenomenon caused by the direct contact between the outer limiting flanging 221, the inner limiting flanging 222 and the lower disc, but also ensure that the outer limiting flanging 221 and the inner limiting flanging 222 have sufficient structural strength to maintain the morphological stability of the annular gap 10b.

[0084] Please refer to Figure 5 and Figure 8 Optionally, the first bracket 10 further includes a lower support 40 provided on the lower disc 12. The lower surface of the lower support 40 protrudes from the lower surface of the lower disc 12, and the lower support 40 is installed on the lower disc 12 through a first fastener 61. It can be understood that the lower support 40 is used to suspend the first bracket 10 above the liquid holding tray to prevent the first bracket 10 from directly contacting the liquid holding tray. Reusing the first fastener 61 to realize the installation and fixation of the lower support 40 can simplify the structure and assembly process of the pot support 101. Of course, in other embodiments, the lower support 40 can also be installed on the lower disc 12 by means such as welding.

[0085] Please refer to Figure 5 and Figure 12 Furthermore, the lower support 40 includes a leg body 41 and a mounting table 42 protruding from the upper surface of the leg body 41. The leg body 41 is provided on the lower surface of the lower disc 12, and the end of the mounting table 42 passes through the lower disc 12 and is connected to the mounting portion 20b through a first fastener 61. In this way, the structure is simple and easy to implement.

[0086] Optionally, the upper end of the mounting table 42 abuts against the lower surface of the mounting portion 20b, and the first fastener 61 passes through the mounting table 42 and connects the mounting portion 20b. In this way, the lower support 40 plays a role in limiting and supporting the support structure 20, enabling the support structure 20 to be suspended above the lower plate 12, avoiding the obvious heat conduction problem caused by the direct contact between the support structure 20 and the lower plate 12, thereby reducing the heat dissipation degree of the support structure 20 and the upper plate 11.

[0087] To further improve the heat conduction problem between the support structure 20 and the lower plate 12, further, the pot support further includes a heat insulation pad (not shown in the drawings), and the heat insulation pad is clamped between the mounting table 42 and the mounting portion 20b. Of course, in other embodiments, the heat insulation pad may not be provided.

[0088] Optionally, the first fastener 61 is configured as a bolt, and the mounting portion 20b is correspondingly provided with a first mounting hole 223, and the first fastener 61 is locked to the first mounting hole 223. In this way, the structure is simple and convenient for installation.

[0089] Please refer to Figure 5 , optionally, the pot support 101 further includes a second fastener 62. The leg body 41 is provided with a second mounting hole 411, and the lower plate 12 is correspondingly provided with a mounting through hole 124 for the second mounting hole 411. The second fastener 62 passes through the mounting through hole 124 and connects the second mounting hole 411. Optionally, the second fastener 62 is configured as a bolt. In this way, the first fastener 61 and the second fastener 62 jointly limit and mount the lower support 40 on the lower plate 12, which can improve the installation stability and reliability of the lower support 40. Of course, in other embodiments, the second fastener 62 may not be provided.

[0090] To improve the thermal efficiency of the cooker, please refer to Figure 5 , Figure 7 and Figure 11 , further, a reflection structure is provided in the cavity, and the reflection structure is used to reflect the heat transferred from the upper plate 11 to the cavity upward. In this way, the heat dissipation rate of the upper plate 11 can be reduced, and the heat can be retained on the upper plate 11 as much as possible to improve the thermal efficiency of the cooker. Of course, in other embodiments, the reflection structure may not be provided.

[0091] The reflection structure includes a reflector 31 provided in the cavity 10a, and the reflector 31 is used to reflect the heat transferred from the upper plate 11 to the cavity 10a back to the upper plate 11. In this way, the structure is simple and easy to assemble and implement. Of course, in other embodiments, the reflection structure may include a reflection layer covering the upper surface of the lower plate 12; specifically, optionally, the reflection layer is configured as a reflection coating, a reflection plating layer, a reflection deposition layer or a polished mirror layer (i.e., a mirror layer formed by polishing), and the present application does not make specific limitations thereto.

[0092] Optionally, the reflector 31 is spaced above the lower disk 12 and clamped between the support plate 22 and the mounting table 42. In this way, it is possible to avoid obvious heat conduction caused by direct contact between the reflector 31 and the lower disk 12, and the support plate 22 and the mounting table 42 together realize the limit installation of the reflector 31, which can improve the stability of the relative position of the reflector 31 in the cavity 10a.

[0093] Please refer to Figure 5 and Figure 11 , optionally, the reflector 31 is provided with a limiting hole 311, and a step portion 421 corresponding to the limiting hole 311 is provided on the side wall surface of the mounting table 42, and the hole edge of the limiting hole 311 abuts against the step portion 421. In this way, through the mutual cooperation of the limiting hole 311 and the step portion 421, the installation of the reflector 31 can be made more stable.

[0094] In the embodiment where the pot support 101 has the lower support 40 and the reflector 31, the assembly process of the pot support 101 includes: first, installing the lower support 40 on the lower disk 12, then sleeving the reflector 31 on the mounting table 42 of the lower support 40 through the limiting hole 311, then covering the upper disk 11 and the support structure 20 pre-fixed on the upper disk 11 together on the lower disk 12, and finally passing the first fastener 61 through the mounting table 42 and connecting it to the support plate 22 of the support structure 20. As the first fastener 61 is locked with the first mounting hole 223, the support plate 22 can tightly abut the reflector 31 against the mounting table 42. It can be seen that the overall assembly process of the pot support 101 of the technical solution of the present invention is relatively convenient and fast, thereby improving production efficiency.

[0095] It can be understood that the number of reflectors 31 can be only one, as Figure 5 shown, or there can be multiple, as Figure 6 shown.

[0096] Optionally, the material of the reflector 31 is configured as a metal, such as mirror stainless steel; or, the upper surface of the reflector 31 is covered with a reflective layer (not shown in the drawings). Specifically optionally, the reflective layer is configured as a reflective coating, a reflective plating layer, a reflective deposition layer or a polished mirror layer (i.e., a mirror layer formed by polishing), and the present application does not make specific limitations on this. For example, the reflective layer is a galvanized layer, that is, the reflector 31 is configured as a galvanized sheet.

[0097] For the convenience of cleaning the exposed outer surfaces of the upper plate 11 and the lower plate 12, optionally, the upper surface of the upper plate 11 and the lower surface of the lower plate 12 are covered with an enamel layer (not shown in the drawings). That is, an enamel layer is formed on the upper surface of the upper plate 111 and the lower surface of the lower plate 12 by means of an enamel process. The enamel layer is not only easy to clean and maintain, but also can enhance the aesthetics of the first bracket 10. Moreover, since the outer surfaces of both the upper plate 11 and the lower plate 12 have an enamel layer, the overall appearance of the first bracket 10 can be made more consistent. Of course, in other embodiments, only the upper surface of the upper plate 11 or the lower surface of the lower plate 12 may be covered with an enamel layer.

[0098] Without loss of generality, the higher the temperature of an object, the greater the total energy it radiates. It can be understood that when using the cooking appliance, the upper plate 11 is in a high-temperature heat storage state. If more heat of the upper plate 11 can be transferred to the cooking utensil in the form of thermal radiation, the thermal efficiency of the cooking appliance can be further improved. Therefore, further, the upper surface of the upper plate 11 is covered with a far-infrared radiation structure (not shown in the drawings). In this way, more energy of the upper plate 11 can be converted into thermal radiation energy through the far-infrared radiation structure and radiated to the cooking utensil. Of course, in other embodiments, the far-infrared radiation structure may not be provided.

[0099] The far-infrared radiation structure is configured as an enamel layer. That is, the material used for the upper plate 11 in the enamel process is a far-infrared radiation enamel material. Of course, in other embodiments, ordinary enamel materials may also be used.

[0100] It is worth mentioning that in the embodiment where the outer surface of the upper plate 11 has an enamel layer, since the reflector 31 and the upper plate 11 are separately provided and are assembled into one body by the first fastener 61, rather than the reflector 31 being welded and fixed to the upper plate 11, the reflector 31 will not undergo the enamel process together with the upper plate 11, which can avoid the problem that the reflector 31 turns black due to the high-temperature environmental conditions of the enamel process and the reflection performance fails.

[0101] Please refer to Figure 1 、 Figure 5 and Figure 7 , in an embodiment, the pot bracket 101 further includes a second bracket 70 and an upper support 50. The upper support 50 is provided at the top of the first bracket 10 and / or the second bracket 70. The top of the upper support 50 has a bearing surface 50a for supporting the item to be heated. The top of the second bracket 70 has a guiding surface 70a disposed around the central hole 102. The guiding surface 70a is lower than the bearing surface 50a and is disposed on one side of the top of the first bracket 10 close to the central hole 102.

[0102] Thus, by adding a second bracket 70 on the basis of the cooking appliance configured with the first bracket 10, making the first bracket 10 surround the second bracket 70, and making the second bracket 70 surround the central hole 102, the flame generated by the burner of the cooking appliance can be surrounded within the second bracket 70, so that the heat of the flame generated by the burner is concentrated within the second bracket 70 to the greatest extent, forming a high-temperature zone in the area within the second bracket 70 and a low-temperature zone in the area between the second bracket 70 and the first bracket 10, and the flame and high-temperature flue gas in the high-temperature zone play a main heating role on the cooking utensil.

[0103] Specifically, place the cooking utensil on the upper support 50 so that the bottom surface of the cooking utensil is connected to the bearing surface 50a of the upper support 50. Since the height of the bearing surface 50a is higher than the guiding surface 70a of the second bracket 70, there is a gap between the guiding surface 70a and the bottom of the cooking utensil. The high-temperature flue gas flows from the high-temperature zone to the low-temperature zone along the gap between the guiding surface 70a and the bottom of the cooking utensil, so that the high-temperature flue gas in the low-temperature zone heats the cooking utensil, and finally flows out of the first bracket 10 through the gap between the top of the upper plate 11 and the bottom of the cooking utensil, so that the high-temperature flue gas exchanges heat with the cooking utensil sufficiently. Moreover, since the flame of the burner and the high-temperature flue gas generated by the burner will heat the top of the second bracket 70, the top of the second bracket 70 can also play a role in exchanging heat with the cooking utensil to further improve the heating effect.

[0104] In this way, after the high-temperature flue gas exchanges heat with the cooking utensil sufficiently, it can flow out of the first bracket 10 through the gap between the top of the upper plate 11 and the bottom of the cooking utensil, and the flow rate of the high-temperature flue gas is accelerated to increase the convective heat transfer intensity between the high-temperature flue gas and the cooking utensil.

[0105] It can be understood that the gap between the guiding surface 70a and the bottom of the cooking utensil and the gap between the top of the upper plate 11 and the bottom of the cooking utensil together constitute the smoke exhaust passage 103 of the high-temperature flue gas. In order to extend the residence time of the flue gas in the smoke exhaust passage 103 and thus extend the heat exchange duration between the flue gas and the bottom of the cooking utensil, optionally, the top of the upper plate 11 has a smoke exhaust surface 11a, and the smoke exhaust surface 11a surrounds the outer circumference of the guiding surface 70a and is spaced from the guiding surface 70a in the radial direction of the central hole 102 to form a buffer gap 104.

[0106] In this way, in the recessed space formed between the outer peripheral edge of the second bracket 70 and the upper surface of the upper plate 11, when the high-temperature flue gas flows outward along the guiding surface 70a of the second bracket 70, a phenomenon of partial air flow detachment will occur at the buffer gap 104, and eddy currents will be generated here, which can disrupt the original stable laminar flow of the high-temperature flue gas, conducive to extending the residence time of the high-temperature flue gas in the smoke exhaust passage 103 and thus extending the heat exchange duration between the high-temperature flue gas and the bottom of the cooking utensil.

[0107] Please refer to Figure 5 , optionally, the height of the smoke exhaust surface 11a is higher than that of the diversion surface 70a. The upper surface of the upper plate 11 further has a guiding surface 11b connected to the inner periphery of the smoke exhaust surface 11a. The guiding surface 11b extends downwardly and obliquely in a direction close to the central hole 102. A buffer cavity 105 is formed at an interval between the guiding surface 11b and the second bracket 70. The buffer cavity 105 communicates with the buffer gap 104. In this way, the gas separated from the high-temperature flue gas at the buffer gap 104 can enter the buffer cavity 105, which is beneficial to forming more and more significant eddy currents of the high-temperature flue gas at the buffer gap 104, thereby further prolonging the residence time of the high-temperature flue gas in the smoke exhaust passage 103.

[0108] It can be understood that when using the cooking appliance, the second bracket 70 is closer to the burner in the central hole 102, so it has a higher temperature. If more heat of the second bracket 70 can be transferred to the cooking utensil in the form of thermal radiation, the thermal efficiency of the cooking appliance can be further improved. Therefore, further, the upper surface of the second bracket 70 is covered with a far-infrared radiation structure. In this way, more energy of the second bracket 70 can be converted into thermal radiation energy through the far-infrared radiation structure and radiated to the cooking utensil. Of course, in other embodiments, the far-infrared radiation structure may not be provided.

[0109] Optionally, the far-infrared radiation structure is configured as an enamel layer. That is, the material used by the second bracket 70 in the enamel process is far-infrared radiation enamel material. Of course, in other embodiments, ordinary enamel material may also be used.
