[0043] The realization, functional features and advantages of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0044] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0045] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0046] In addition, if descriptions such as "first" and "second" are involved in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between the respective embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0047] In the prior art, the pot support generally includes a spliced upper plate and a lower plate. The side edges of the upper plate and the lower plate are spliced and fixed together by a welding process to form a heat insulation cavity between the upper plate and the lower plate, so as to achieve the effect of retaining heat in the upper plate as much as possible. However, this solution still has the problem that the heat of the upper plate heats the air in the cavity and is transmitted to the lower plate through the air in the cavity, resulting in a relatively high heat dissipation rate of the upper plate. On the other hand, this solution also has the problem that the heat of the upper plate is significantly transmitted to the lower plate by means of heat conduction, which also leads to a high heat dissipation rate of the upper plate.

[0048] In view of this, the present utility model proposes a pot support that can reduce the heat dissipation rate of the upper plate of the pot support.

[0049] Without loss of generality, the pot support 101 is usually arranged on the liquid receiving tray of the cooking appliance and is used for supporting a workpiece to be heated, such as a cooking utensil (including but not limited to a flat pan, a pointed bottom pan, etc.). Please refer to Figures 1 to 4 , in an embodiment provided by the present utility model, the pot support 101 includes a first support 10. The first support 10 includes a separately arranged upper plate 11 and a lower plate 12, and a cavity 10a is formed between the upper plate 11 and the lower plate 12. The first support 10 encloses a central hole 102, which is usually used to accommodate 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.

[0050] Please refer to Figures 1 to 5 , in an embodiment, further, the pot support further includes a support structure 20, and the support structure 20 connects the upper plate 11 and the lower plate 12. In this way, the support structure 20 is used to realize the installation and fixation of the upper plate 11 and the lower plate 12, and the structure is simple and easy to implement. Of course, in other embodiments, the upper plate 11 and the lower plate 12 can also be directly welded and fixed without additionally providing the support structure 20.

[0051] Further, the support structure 20 includes a support plate 22 provided on the upper plate 11 and a lower support 40 provided on the lower plate 12. The lower surface of the lower support 40 protrudes from the lower surface of the lower plate 12. The support plate 22 is mounted on the lower support 40 to relatively fix the upper plate 11 and the lower plate 12. In this way, the structure is simple and easy to install. Of course, in other embodiments, other forms of the support structure 20 may also be used to relatively fix the upper plate 11 and the lower plate 12. For example, the support structure 20 includes a support plate 22 fixedly welded to the upper plate 11, and the lower end of the support plate 22 is attached to the lower plate 12 by screws.

[0052] 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. By reusing the lower support 40 to install and fix the upper plate 11 and the lower plate 12, it is beneficial to simplify the structure of the pot bracket 101 and reduce its manufacturing cost.

[0053] Please refer to Figure 5 、 Figure 6 and Figure 11 Further, the lower support 40 includes a leg body 41 and a mounting table 42 provided on the leg body 41. The leg body 41 protrudes from the lower surface of the lower plate 12. The end of the mounting table 42 penetrates into the cavity 10a and is mounted on the support plate 22. In this way, the structure is simple and easy to implement.

[0054] Please refer to Figure 5 and Figure 6 Further, the pot bracket 101 further includes a first fastener 61. The support plate 22 is fixed to the mounting table 42 by the first fastener 61. In this way, the structure is simple and the installation is reliable. In this embodiment, optionally, the edge of the support plate 22 is bent upwardly towards the upper plate 11 to form a support flange 221. The support flange 221 is welded and fixed to the upper plate 11. That is, the support plate 22 can be pre-welded to the upper plate 11 and then installed on the mounting table 42 by the first fastener 61 to simplify the assembly process of the pot bracket 101.

[0055] Optionally, the first fastener 61 is configured as a bolt. The support plate 22 is correspondingly provided with mounting holes. The first fastener 61 passes through the mounting table 22 and is attached to the mounting holes. In this way, the structure is simple and convenient for installation. Of course, in other embodiments, the first fastener 61 can also be configured as a rivet or a buckle, etc.

[0056] It can be understood that when the spread area of the flame is relatively large, the flame will directly contact the upper plate of the pot bracket 101 and transfer heat to the upper plate, resulting in the upper plate being heated to a relatively high temperature. If a good heat conduction and heat convection path is formed between the upper plate and the lower plate, part of the heat of the flame will continuously be transferred to the lower plate, the liquid holding tray and the stove surface of the stove through this heat conduction path, which is not conducive to the stove maintaining a relatively high thermal efficiency level.

[0057] Therefore, please refer to Figure 5 and Figure 6 Further, the pot support further includes a reflection structure 30, which is disposed in the cavity 10a and is used to reflect the heat transferred from the upper plate 11 to the cavity 10a upward. The reflection structure 30 is connected to the support structure 20. In this way, by providing the reflection structure 30 in the cavity 10a, it is possible to both hinder the formation of heat convection and reflect the heat transferred downward from the upper plate 11 back to the upper plate 11, so that the heat can be retained in the upper plate 11 as much as possible and the problem of high heat dissipation rate of the upper plate 11 can be improved, thereby improving the thermal efficiency of the cooker. Secondly, reusing the support structure 20 as the installation structure of the reflection structure 30 is beneficial to simplifying the structure of the pot support 101 and reducing its manufacturing cost.

[0058] Optionally, the reflection structure 30 includes a reflection plate 31 disposed in the cavity 10a, and the reflection plate 31 is connected to the support structure 20. In this way, the structure is simple and easy to implement. Among them, the reflection plate 31 can either have a good reflection effect itself, such as being configured as a polished stainless steel plate, or its surface facing the upper plate 11 is covered with a reflection coating, a reflection plating layer or a reflection deposition layer.

[0059] Optionally, the reflection structure 30 may further include a reflection layer covering the upper surface of the lower plate 12. Specifically optionally, the reflection layer can be 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 on this.

[0060] Further, the reflection plate 31 includes a plate body 312 and a supporting portion 313 connected to each other. The plate body 312 is connected to the support structure 20 and is used to reflect the heat transferred from the upper plate 11 to the cavity 10a upward. The supporting portion 313 abuts against the lower surface of the upper plate 11. In this way, using the supporting portion 313 to support the upper plate 11 can improve the installation reliability and stability of the upper plate 11. Of course, in other embodiments, the supporting portion 313 may not be provided.

[0061] Please refer to Figure 5 , Figure 7 and Figure 11 , optionally, the plate body 312 is provided with a limiting hole 311, and the side wall surface of the installation table 42 is provided with a step portion 421 corresponding to the limiting hole 311, 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 plate body 312 can be made more stable.

[0062] Please refer to Figure 2 and Figure 5, 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 on 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. That is, in this embodiment, the annular gap 10b includes an outer ring gap 10c located at the outer periphery of the first bracket 10 and an inner ring gap 10d located at the inner periphery of the first bracket 10.

[0063] 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 that only the upper plate 11 and the lower plate 12 have an annular gap 10b at the relative positions of the inner periphery.

[0064] In this way, by setting the annular gap in this embodiment, the upper plate 11 and the lower plate 12 can be separated in the vertical distribution direction, and significant heat conduction problems caused by their direct contact can be avoided, so that the heat dissipation rate of the upper plate 11 can be reduced, and the heat can be retained in the upper plate 11 as much as possible to improve the thermal efficiency of the cooking appliance. That is, through the combination of the annular gap and the reflection structure mentioned above, the technical solution of the present utility model can improve the problem of high heat dissipation rate of the upper plate 11 in multiple aspects.

[0065] To ensure the effectiveness of the annular gap 10b in reducing the heat dissipation rate of the upper plate 11, optionally, the support structure 20 and the supporting portion 313 jointly maintain the annular gap 10b, that is, the support structure 20 and the supporting portion 313 jointly keep an annular gap 10b between the upper plate 11 and the lower plate 12 continuously. Of course, in other embodiments, it may also be that only the support structure 20 plays the role of maintaining the annular gap 10b.

[0066] Please refer to Figures 5 to 7 , further, the reflector 31 further includes a limiting piece 316, and the limiting piece 316 is connected to the side of the supporting portion 313 away from the plate body 312 and at least partially extends into a partial area of the annular gap 10b in the circumferential direction.

[0067] In this way, the limiting piece 316 extends into the annular gap 10b, which 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 tendency to relatively shift and cause a change in the annular gap 10b, the limiting piece 316 can block between the upper plate 11 and the lower plate 12, keep an annular gap 10b between the two, and avoid the occurrence of a situation where they are in large-area direct contact, thereby facilitating the retention of heat in the upper plate 11 as much as possible.

[0068] It can be understood that the reflector 31 of the present utility model has two functional effects. It can not only reflect the heat transferred from the upper plate 11 to the cavity 10a back, but also maintain the effectiveness of the annular gap 10b, thereby improving the problem of high heat dissipation rate of the upper plate 11 in multiple aspects.

[0069] It should be noted that since the limiting piece 316 only extends into a partial area in the circumferential direction of the annular gap 10b, even if the limiting piece 316 abuts against both the upper plate 11 and the lower plate 12 simultaneously, it will not cause the entire periphery of the lower plate 12 to form a closed-loop heat conduction path, thereby avoiding the problem that the heat of the upper plate 11 is significantly thermally conducted to the lower plate 12 through the limiting piece 316.

[0070] Optionally, the limiting piece 316, the supporting portion 313 and the plate body 312 are integrally formed. In this way, the structure is simple and easy to implement, and it can enhance the connection strength between the limiting piece 316, the supporting portion 313 and the plate body 312, which is beneficial to maintaining the relative position of the limiting piece 316 in the annular gap 10b. Of course, in other embodiments, at least two of the limiting piece 316, the supporting portion 313 and the plate body 312 may be separately provided and installed as a whole by means of welding, screwing or riveting.

[0071] In the embodiment where the limiting piece 316, the supporting portion 313 and the plate body 312 are integrally formed, optionally, the material of the reflector 31 is configured as metal, and the limiting piece 316 is bent outwards from the outer edge of the supporting portion 313. In this way, the limiting piece 316 is formed by stamping and bending a part of the reflector 31, with a simple structure and easy to form, and metal has a good reflection effect. Of course, in other embodiments, the material of the reflector 31 can also be other materials, or other forming processes can be adopted, such as integrally forming the limiting piece 316 through a casting forming process.

[0072] In the embodiment where the pot support 101 has the lower support 40 and the support plate 22, the assembly process of the pot support 101 includes: first, installing the lower support 40 on the lower plate 12, then sleeving the reflector 31 on the mounting table 42 of the lower support 40 through the limiting holes 311, then covering the upper plate 11 and the support plate 22 pre-fixed on the upper plate 11 together on the lower plate 12, and finally passing the first fastener 61 through the mounting table 42 and connecting it with the support plate 22. As the first fastener 61 is locked with the first mounting hole 223, the support plate 22 can tightly press 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 utility model is relatively convenient and fast, thereby improving the production efficiency.

[0073] 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 assembled into one body by the first fastener 61 instead of welding the reflector 31 to the upper plate 11, the reflector 31 will not undergo the enameling process together with the upper plate 11, thus avoiding the problem that the reflector 31 turns black due to the high-temperature environment conditions of the enameling process and the reflection performance fails.

[0074] Optionally, the limiting piece of the reflector 31 abuts against one of the upper plate 11 and the lower plate 12, and a fitting gap is formed at an interval from the other. In this way, not only can the installation position stability of the reflector 31 be improved, but also the problem that it is difficult to assemble the upper and lower plates 12 and difficult to form the annular gap 10b due to the manufacturing tolerance causing the thickness of the limiting piece to be greater than the width of the annular gap 10b can be avoided, that is, it is also convenient for the assembly of the reflector 31 and the first bracket 10.

[0075] Please refer to Figure 5 , in this embodiment, optionally, the limiting piece abuts against the upper plate 11 and is arranged at an interval from the lower plate 12. For example, in the embodiment where the annular gap 10b is configured to be 1 mm, the material thickness of the limiting piece is configured to be 0.8 mm, then the gap width between the third segment 313c of the limiting piece and the lower outer flange 122 is 0.2 mm, and the gap width between the third segment 313c and the lower inner flange 123 is also 0.2 mm. In this way, not only can the obvious heat conduction phenomenon caused by the direct contact between the limiting piece and the lower plate 12 be avoided, but also the limiting piece can have sufficient structural strength to maintain the morphological stability of the annular gap 10b.

[0076] Of course, in another embodiment, it may also be that the limiting piece of the reflector 31 is arranged at an interval from both the upper plate 11 and the lower plate 12. In other embodiments, it may also be that the limiting piece of the reflector 31 abuts against both the upper plate 11 and the lower plate 12.

[0077] In order to further reduce the heat dissipation rate of the upper plate 11, please refer to Figure 6 and Figure 7 , optionally, the cavity 10a and the plate body 312 are annularly arranged. In this way, the annular cavity 10a can play a good heat insulation effect, and at the same time the annular plate body 312 can reflect more heat back to the upper plate 11. Of course, in other embodiments, there may also be multiple plate bodies 312, and the multiple plate bodies 312 are arranged at intervals along the circumferential direction of the central hole 102.

[0078] In order to keep both the outer ring gap 10c and the inner ring gap 10d effective, please refer to Figure 5 and Figure 7, optionally, a plurality of limiting pieces 316 are provided, including an outer limiting piece 314 provided at the outer peripheral edge of the plate body 312 and an inner limiting piece 315 provided at the inner peripheral edge of the plate body 312. The outer limiting piece 314 correspondingly extends into the annular gap 10b at the outer peripheral edge of the first bracket 10, and the inner limiting piece 315 correspondingly extends into the annular gap 10b at the inner peripheral edge of the first bracket 10. In this way, the inner limiting piece 315 and the outer limiting piece 314 jointly maintain the stability of the first bracket 10 at the two annular gaps 10b at the inner and outer peripheral edges. Of course, in other embodiments, only the outer limiting piece 314 or only the inner limiting piece 315 may be provided.

[0079] Optionally, the width value range of the annular gap 10b is configured to be 0.5 mm to 1.5 mm. Optionally, in this embodiment, the width value range of the annular gap 10b is configured to be 0.8 mm to 1 mm. It can be understood that if the width value 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 prone to dirt accumulation, which is not conducive to the first bracket 10 maintaining a good sanitary state. If the width value 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 piece 316 will be too small (the thickness is too thin), which is not conducive to the structural strength of the limiting piece 316.

[0080] Please refer to Figure 7 , optionally, the plate body 312 is annularly arranged, and an outer limiting piece 314 and an inner limiting piece 315 adjacent to each other form a limiting piece group. A plurality of limiting piece groups are provided and are spaced apart along the circumferential direction of the plate body 312. That is, in this embodiment, the number of the outer limiting pieces 314 and the inner limiting pieces 315 is equal and in a one-to-one correspondence. In this way, on the one hand, the overall weight of the reflector 31 is relatively small and less material is used, which is conducive to the light weight and cost control of the pot bracket 101; on the other hand, a plurality of limiting piece groups can better maintain the structural form of the annular gap 10b. Of course, in other embodiments, only one limiting piece group may be provided; or an outer limiting piece 314 and a plurality of adjacent inner limiting pieces 315 jointly form a limiting piece group, or an inner limiting piece 315 and a plurality of adjacent outer limiting pieces 314 jointly form a limiting piece group.

[0081] It should be noted that in the embodiments of the present invention, "a plurality" refers to two or more; "adjacent" refers to the relative positional relationship between the outer limiting piece 314 and the inner limiting piece 315, rather than the absolute positional relationship between the outer limiting piece 314 and the inner limiting piece 315, that is, it does not mean that the outer limiting piece 314 and the inner limiting piece 315 are arranged in a state of being adjacent to each other.

[0082] Please refer to Figure 7 , optionally, the outer limiting piece 314 and the inner limiting piece 315 in the same limiting piece group are arranged oppositely in a radial direction of the plate body 312. That is, a reference ray is made from the center of the central hole 102, and the reference ray passes through the middle parts of the inner limiting piece 315 and the outer limiting piece 314 of the same limiting piece group. In this way, it is convenient for the processing and manufacturing of the reflector 31 and its assembly with the first bracket 10. Of course, in other embodiments, the outer limiting piece 314 and the inner limiting piece 315 in the same limiting piece group may also be arranged staggeredly in a radial direction of the plate body 312.

[0083] Please refer to Figure 5 and Figure 7 , optionally, the plate body 312 includes a first plate segment 31a and two second plate segments 31b. The two second plate segments 31b are respectively connected to opposite sides of the first plate segment 31a. The second plate segment 31b extends obliquely upward in a direction away from the first plate segment 31a. The outer limiting piece 314 is arranged on the outer periphery of the second plate segment 31b located on the outer circumference of the first plate segment 31a, and the inner limiting piece 315 is arranged on the inner periphery of the second plate segment 31b located on the inner circumference of the first plate segment 31a. In this way, it can not only increase the structural strength of the plate body 312, but also increase its reflection area. Moreover, the cross-sectional shape of the plate body 312 is roughly U-shaped, which is beneficial to making the reflected heat more concentrated in the middle of the top wall of the upper disc 11, improving the temperature of the core area of the upper disc 11, and being beneficial to improving the thermal efficiency. Of course, in other embodiments, the plate body 312 may also adopt other structural forms, such as only setting the first plate segment 31a, or only setting one first plate segment 31a and one second plate segment 31b, etc.

[0084] Please refer to Figure 5 and Figure 7 , optionally, the supporting part 313 includes a connected first segment 313a and a second segment 313b. The first segment 313a is connected to the second plate segment 31b and the plate body 312, and is arranged opposite to the limiting piece 316. The second segment 313b is connected to the limiting piece 316 and abuts against the lower surface of the upper disc 11. In this way, the second segment 313b abuts against and supports the upper disc 11, which can improve the installation stability of the upper disc 11 and the reflector 31. Secondly, the profile and weight of the plate body 312 are both small, which is beneficial to realizing the lightweight design of the pot bracket 101.

[0085] Optionally, the first segment 313a and the second plate segment 31b are smoothly transitioned at the connection, that is, in the embodiment where the limiting piece 316, the supporting portion 313 and the plate body 312 are integrally stamped, the first segment 313a and the second plate segment 31b belong to the same drawn surface. In this way, the structure of the stamping die can be simplified and the manufacturing yield rate of the reflector 31 can be improved. Of course, in other embodiments, the first segment 313a and the second plate segment 31b may also intersect at a non-zero angle.

[0086] Please refer to Figure 1 、 Figure 5 and Figure 9 , optionally, the upper disc 11 includes an upper disc plate 111, an upper outer flange 112 bent downward from the outer peripheral edge of the upper disc plate 111, and an upper inner flange 113 bent downward from the inner peripheral edge of the upper disc plate 111. The outer ring gap 10c is located on the side where the inner wall surface of the upper outer flange 112 is located, and the inner ring gap 10d is located on the side where the inner wall surface of the upper inner flange 113 is located. That is, the outer ring gap 10c is located on the side of the upper outer flange 112 close to the central hole 102, and the inner ring gap 10d is located on the side of the upper inner flange 113 away from the central hole 102. In this way, it is not easy to observe the outer ring gap 10c and the inner ring gap 10d from the upper view (i.e., the top view angle) or the side view (i.e., the side view angle) of the first bracket 10, which is beneficial to improving the neatness and aesthetics of the first bracket 10.

[0087] Of course, in some other embodiments, only the upper outer flange 112 may be provided, or only the upper inner flange 113 may be provided. In still other embodiments, the inner ring gap 10d is located on the side where the outer wall surface of the upper inner flange 113 is located, and the outer ring gap 10c is located on the side where the outer wall surface of the upper outer flange 112 is located. In other embodiments, the upper outer flange 112 and the upper inner flange 113 may not be provided, and an annular gap 10b is formed at intervals in the vertical direction between the plate surface of the upper disc plate 111 and the side edge of the lower disc 12.

[0088] Please refer to Figure 2 、 Figure 5 and Figure 10, optionally, the lower plate 12 includes a lower plate body 121, a lower outer flange 122 bent upward from the outer peripheral edge of the lower plate body 121, and a lower inner flange 123 bent upward from the inner peripheral edge of the lower plate body 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 arranged 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 arranged 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 an annular gap 10b is formed at intervals between the plate surfaces of the upper plate body 111 and the lower plate body 121 in the up and down directions.

[0089] Please refer to Figure 5 and Figure 6 , optionally, the pot support 101 includes at least two reflecting plates 31 distributed in the up and down directions. One of the reflecting plates 31 is configured to have a structure of a plate body 312 and a limiting piece, and the remaining reflecting plates 31 are configured to only have the structure of the plate body 312. For example, Figure 5 in the illustrated embodiment, the pot support 101 includes two reflecting plates 31, and the upper reflecting plate 31 has a plate body 312 and a limiting piece (as Figure 7 shown), and the lower reflecting plate 31 only has the plate body 312 without a limiting piece (as Figure 8 shown).

[0090] In this way, the uppermost reflecting plate 30 plays a main reflecting role to directly reflect the heat in the cavity 10a back to the upper plate 11, while the remaining reflecting plates 30 can make the heat in the cavity 10a reflect upward as much as possible, and at the same time enable the uppermost reflecting plate 30 to gather more heat and use the uppermost reflecting plate 30 to reflect more heat back to the upper plate 11. In this way, at least two reflecting plates 30 distributed in the up and down directions can constitute a multiple reflection effect, thereby improving the overall reflection effect of the reflecting plates 30, reducing the heat dissipation rate of the upper plate 11, and further improving the thermal efficiency of the cooker.

[0091] Of course, in some other embodiments, it may also be that the reflecting plate 31 at other positions has a plate body 312 and a limiting piece. For example, the lowermost reflecting plate 31 has a plate body 312 and a limiting piece, while the reflecting plates 31 at the remaining positions only have the plate body 312. In other embodiments, it may also be that only one reflecting plate 31 is provided, and this reflecting plate 31 has a structure of both a plate body 312 and a limiting piece at the same time.

[0092] Please refer to Figure 5 , Figure 7 and Figure 8, in an embodiment where there are at least two reflector plates, optionally, one of two adjacent reflector plates 31 protrudes towards the other with a support convex portion 319, and the support convex portion 319 abuts against the other reflector plate 31, so that a gap is formed between two opposite plate surfaces of the two adjacent reflector plates 31. In this way, the support convex portion 319 formed by the reflector plate 31 itself is used to achieve the spacing effect, and the structure is simple and easy to implement. Of course, in other embodiments, an additional support member may also be provided, for example, a support block is welded on the plate surface of the reflector plate 31.

[0093] Optionally, the support convex portion 319 includes a positioning flange bent from the hole edge of the limit hole 311. In this way, the positioning flange is formed by bending the hole edge of the limit hole 311 to achieve the spacing effect between the plate surfaces of the two adjacent reflector plates 31, and the structure is simple and easy to implement. Of course, in other embodiments, the support convex portion may also be provided at other positions of the reflector plate 31.

[0094] Please refer to Figure 5 and Figure 7 , optionally, the limit hole 311 of the uppermost reflector plate 31 also has an upwardly bent positioning flange, and the positioning flange abuts against the lower surface of the support plate 22. In this way, the positioning flange formed by the material originally located at the position of the limit hole 311 is used to abut against the support plate 22, which can reduce the height dimension of the support plate 22, thereby reducing the material cost of the support plate 22 and lowering the manufacturing cost of the pot support 101.

[0095] It can be understood that the way to achieve the multiple reflection effect is not limited to the above-mentioned setting of multiple reflector plates. In other embodiments, only one reflector plate 31 may be provided, and a reflective coating is covered on the lower cavity surface of the cavity 10a (i.e., the upper surface of the lower disk 12), and the reflector plate is spaced above the reflective coating.

[0096] Please refer to Figure 5 , Figure 10 and Figure 11 , further, 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 disk 12 is provided with a mounting through hole 124 corresponding to the second mounting hole 411. The second fastener 62 passes through the mounting through hole 124 and connects to 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 disk 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.

[0097] Please refer to Figure 1 , Figure 5 and Figure 6, Further, the pot support 101 further includes a second support 70 and an upper support 50. The upper support 50 is disposed on the top of the first support 10 and / or the second support 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 support 70 has a diversion surface 70a disposed around the central hole 102. The diversion surface 70a is lower than the bearing surface 50a and is disposed on one side of the top of the first support 10 close to the central hole 102.

[0098] In this way, by adding the second support 70 on the basis of the cooking appliance configured with the first support 10, the first support 10 is disposed around the second support 70, and the second support 70 is disposed around the central hole 102, the flame generated by the burner of the cooking appliance can be enclosed within the second support 70, so that the heat of the flame generated by the burner is concentrated within the second support 70 to the greatest extent, to form a high-temperature zone in the area within the second support 70 and a low-temperature zone in the area between the second support 70 and the first support 10, and the main heating effect on the cooking utensil is achieved by the flame and high-temperature flue gas in the high-temperature zone.

[0099] 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 diversion surface 70a of the second support 70, there is a gap between the diversion 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 diversion 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 support 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 fully. Moreover, since the flame of the burner and the high-temperature flue gas generated by the burner will heat the top of the second support 70, the top of the second support 70 can also play a role in exchanging heat with the cooking utensil to further improve the heating effect.

[0100] In this way, after the high-temperature flue gas exchanges heat with the cooking utensil fully, it can flow out of the first support 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 increased to improve the convective heat transfer intensity between the high-temperature flue gas and the cooking utensil.

[0101] Please refer to Figure 5 , it can be understood that the gap between the diversion 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. The smoke exhaust surface 11a surrounds the outer circumference of the diversion surface 70a and is spaced from the diversion surface 70a in the radial direction of the central hole 102 to form a buffer gap 104.

[0102] In this way, a recessed space is formed between the outer peripheral edge of the second support 70 and the upper surface of the upper plate 11. When the high-temperature flue gas flows outward along the flow guiding surface 70a of the second support 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 originally smooth laminar flow of the high-temperature flue gas, is beneficial 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.

[0103] Please refer to Figure 5 , optionally, the height of the smoke exhaust surface 11a is higher than that of the flow guiding surface 70a, and the upper surface of the upper plate 11 further has a guiding surface 11b connected to the inner peripheral edge of the smoke exhaust surface 11a. The guiding surface 11b extends downward and obliquely in the direction close to the central hole 102. A buffer cavity 105 is formed at an interval between the guiding surface 11b and the second support 70, and the buffer cavity 105 is communicated 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 at the buffer gap 104, thereby further extending the residence time of the high-temperature flue gas in the smoke exhaust passage 103.
