[0001] The utility model relates to the technical field of cooking appliances, and particularly to a pot support and a cooking appliance. Background Art

[0002] In the prior art, a pot support usually includes a separately manufactured and formed 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, in this solution, there is still a problem that the heat of the upper plate is significantly transferred to the lower plate by heat conduction, resulting in a relatively high heat dissipation rate of the upper plate.

[0055] The realization, functional features and advantages of the present utility model will be further described in conjunction with embodiments with reference to the accompanying drawings. Specific embodiments

[0056] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 fall within the scope of protection of the present utility model.

[0057] 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 certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0058] In addition, if the embodiments of the present utility model involve descriptions such as "first", "second", etc., 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 scenarios. Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions 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.

[0059] In the prior art, the pot support usually includes an upper plate and a lower plate that are separately manufactured and formed. 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 is significantly transferred to the lower plate by heat conduction, resulting in a relatively high heat dissipation rate of the upper plate.

[0060] In view of this, the present utility model proposes a pot support.

[0061] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, the pot support 101 includes a first support 10. The first support 10 defines a central hole 102 and includes an upper plate 11 and a lower plate 12. The upper plate 11 and the lower plate 12 are separate and spaced apart, and a cavity 10a is formed between the upper plate 11 and the lower plate 12. The upper plate 11 and the lower plate 12 have an annular gap 10b at the relative positions of the outer periphery and / or the inner periphery.

[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 element, such as a cooking utensil (including but not limited to a flat pan, a pointed pan, etc.). The central hole 102 of the pot support 101 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. When the spreading area of the flame is relatively large, the flame will directly contact the upper plate 11 of the pot support 101 and transfer heat to the upper plate 11, resulting in the upper plate 11 being heated to a relatively high temperature. If a good heat conduction path is formed between the upper plate 11 and the lower plate 12, part of the heat of the flame will continuously be transferred to the lower plate 12, the liquid receiving tray, and the cooking surface of the cooking appliance through this heat conduction path, which is not conducive to the cooking appliance maintaining a relatively high thermal efficiency level.

[0063] In the technical solution of the present utility model, by providing an annular gap 10b between the upper plate 11 and the lower plate 12, the upper plate 11 and the lower plate 12 can be spaced apart in the up-and-down distribution direction, and the significant heat conduction problem caused by their direct contact can be avoided. Thereby, 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 cooker.

[0064] 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 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 spaced-apart 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.

[0065] That is, in the present 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.

[0066] Please refer to Figure 5 , Figure 7 and Figure 8 , further, the pot support 101 further includes a support structure 20, and the support structure 20 connects the upper plate 11 and the lower plate 12 to keep an annular gap 10b between the upper plate 11 and the lower plate 12. In this way, the support structure not only plays a role in installing and fixing the upper plate 11 and the lower plate 12, but also plays a role in maintaining the stability of the annular gap 10b and avoiding the problem of the annular gap 10b losing its function.

[0067] In the present embodiment, optionally, the support structure 20 includes a limiting portion 21 provided in the annular gap 10b. In this way, the limiting portion 21 can maintain the stability of the annular gap 10b and avoid the problem of the annular gap 10b losing its function, that is, even if the upper plate 11 and the lower plate 12 have a tendency to shift relative to each other and cause a change in the annular gap 10b, the limiting portion 21 can block between the upper plate 11 and the lower plate 12, keep an annular gap 10b between the two, and avoid the situation of their large-area direct contact, which is conducive to retaining the heat in the upper plate 11 as much as possible. Of course, in other embodiments, the support structure 20 may not be provided.

[0068] 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 miniaturized 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 a good sanitary state. 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.

[0069] Please refer to Figure 8 , in order to make both the outer ring gap 10c and the inner ring gap 10d effective, optionally, the limiting portion 21 is provided with at least two, and includes an outer limiting portion 211 and an inner limiting portion 212. The outer limiting portion 211 is provided in the outer ring gap 10c, and the inner limiting portion 212 is provided in the inner ring gap 10d. In this way, the inner limiting portion 212 and the outer limiting portion 211 jointly maintain the stability of the first bracket 10 at the two annular gaps 10b on the inner and outer peripheries. Of course, in other embodiments, only the outer limiting portion 211 may be provided, or only the inner limiting portion 212 may be provided.

[0070] It can be understood that the specific structure of the support structure 20 can have various forms. For example, further, the support structure 20 further includes a support plate 22 connecting the upper plate 11 and the lower plate 12. The inner limiting portion 212 is provided at the inner edge of the support plate 22 in the radial direction of the first bracket 10, and the outer limiting portion 211 is provided at the outer edge. That is, the support structure 20 also realizes the installation connection between the upper plate 11 and the lower plate 12 through the support plate 22. In this way, by the supporting and structure strengthening effects of the support plate 22, it is beneficial for the limiting portion 21 to maintain its state within the annular gap 10b.

[0071] Of course, in some other embodiments, it may also be that the support plate 22 is only connected to one of the upper plate 11 and the lower plate 12, that is, it does not play the role of realizing the installation connection between the upper plate 11 and the lower plate 12. In other embodiments, it may also be that the support structure 20 is only composed of the limiting portion 21. The limiting portion 21 is fixed to one of the upper plate 11 and the lower plate 12 by welding or the like, and abuts against or is spaced from the other.

[0072] Please refer to Figure 7 and Figure 13, optionally, there are multiple support structures 20, and the multiple support structures 20 are spaced apart along the circumferential direction of the central hole 102. It should be noted that multiple means two or more. In this way, on the one hand, the overall weight of the support structure 20 is small and less material is used, which is beneficial to the light weight and cost control of the pot support 101; on the other hand, the support plates 22 of the multiple support structures 20 can improve the connection strength between the upper plate 11 and the lower plate 12, and the limiting parts 21 of the multiple support structures 20 can better maintain the structural form of the annular gap 10b. Of course, in other embodiments, only one support structure 20 may be provided.

[0073] Please refer to Figure 5 , further, the support plate 22 is fixedly arranged on the upper plate 11 through the inner limiting part 212 and / or the outer limiting part 211. The first bracket 10 further includes a first fastener 61, and the first fastener 61 passes through the lower plate 12 and connects the support plate 22 to assemble the upper plate 11, the lower plate 12 and the support structure 20. In this way, the support structure 20 is pre-fixed on the upper plate 11, and then the assembly is completed by using the first fastener 61. The structure is simple and easy to assemble, and the first fastener 61 is not easily exposed outside. At the same time, the upper plate 11 can maintain a good appearance, which is beneficial to the neatness and beauty of the first bracket 10.

[0074] Of course, the installation method of the support structure 20 is not limited to this. For example, in some other embodiments, it may also be that the support plate 22 is pre-fixed on the lower plate 12 first, and then the upper plate 11 is assembled to the support plate 22 by using the first fastener 61. In other embodiments, other installation methods may also be used to realize the installation of the support plate 22, the upper plate 11 and the lower plate 12. For example, the support plate 22, the upper plate 11 and the lower plate 12 are all fixed by welding.

[0075] Please refer to Figure 5 , Figure 7 and Figure 12 , further, the pot support 101 further includes a lower support 40. The lower surface of the lower support 40 protrudes from the lower surface of the lower plate 12, and the lower support 40 is installed on the lower plate 12 through the first fastener 61. It can be understood that the lower support 40 is used to suspend the first bracket 10 above the liquid receiving tray to prevent the first bracket 10 from directly contacting the liquid receiving 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 plate 12 by means such as welding.

[0076] Please refer to Figure 2 and Figure 9, optionally, the upper plate 11 includes an upper plate 111, an upper outer flange 112 bent downward from the outer peripheral edge of the upper plate 111, and an upper inner flange 113 bent downward from the inner peripheral edge of the upper 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, the outer ring gap 10c and the inner ring gap 10d are not easily observable 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.

[0077] Of course, in some other embodiments, it may also be only the upper outer flange 112 is provided, or only the upper inner flange 113 is 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 by spacing the plate surface of the upper plate 111 and the side edge of the lower plate 12 in the vertical direction.

[0078] 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 by spacing; 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 by spacing. 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 by spacing the plate surface of the upper plate 111 and the plate surface of the lower plate 121 in the vertical direction.

[0079] Please refer to Figure 5 and Figure 8, Further, the support structure 20 further includes a support plate 22 connecting the upper plate 11 and the lower plate 12. The inner edge and the outer edge of the support plate 22 in the radial direction of the first bracket 10 are bent downward to form limiting flanges 221. One limiting flange 221 is provided on the inner wall surface of the upper outer flange 112, and the other limiting flange 221 is provided on the inner wall surface of the upper inner flange 113. In this embodiment, the limiting flange 221 is configured as the limiting portion 21 and functions to maintain the stable shape of the annular gap 10b. In this way, the structure is simple and easy to implement, and the connection strength between the limiting portion 21 and the support plate 22 can be improved. Of course, in some other embodiments, the limiting portion 21 and the support plate 22 may be integrally formed and fixed together by welding or other means; it is also possible that the limiting flange 221 is provided on the lower plate 12.

[0080] Optionally, the materials of the upper plate 11, the lower plate 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 bracket 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 plate 11, the lower plate 12 and the support structure 20.

[0081] There are various ways to fix the limiting flange 221 to the upper plate 11. For example, in one embodiment, the limiting flange 221 is welded and fixed to the upper outer flange 112 and / or the upper inner flange 113. In this way, not only can the connection strength between the limiting flange 221 and the upper plate 11 be improved, which is beneficial to simplifying the structure of the pot bracket 101, but also the welding marks generated during welding can be limited to the area of the upper plate 11 corresponding to the limiting flange 221, that is, the welding marks are limited to the upper outer flange 112 and the upper inner flange 113. Since the upper outer flange 112 and the upper inner flange 113 belong to the non-height visible area of the first bracket 10, the welding marks are not easily noticed, thus improving the aesthetics of the first bracket 10.

[0082] It should be noted that the height visible area of the pot bracket 101 refers to its visual area from a top-down perspective. Correspondingly, the remaining areas outside the height visible area are non-height visible areas.

[0083] Of course, in some other embodiments, the limiting flange 221 may also be provided on the upper plate 11 by bonding or clamping, or only abut against the upper plate 11. In other embodiments, the support plate 22 and the upper plate 11 may also be welded and fixed.

[0084] Optionally, the limiting flanging 221 is in clearance fit with the lower inner flanging 123, and the 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 thickness of the limiting flanging 221 is configured to be 0.8 mm, the clearance width between the limiting flanging 221 and the lower inner flanging 123 and the lower outer flanging 122 is 0.2 mm. In this way, it can not only avoid the obvious heat conduction phenomenon caused by the direct contact between the limiting flanging 221 and the lower disk, but also ensure that the limiting flanging 221 has sufficient structural strength to maintain the morphological stability of the annular gap 10b.

[0085] To facilitate the cleaning of the exposed outer surfaces of the upper disk 11 and the lower disk 12, optionally, the upper surface of the upper disk 11 and the lower surface of the lower disk 12 are covered with an enamel layer (not shown in the drawings). That is, the enamel layer is formed on the upper surface of the upper disk plate 111 and the lower surface of the lower disk 12 by using the enamel process. The enamel layer is not only easy to clean and maintain, but also can improve the aesthetics of the first bracket 10. Moreover, since the outer surfaces of both the upper disk 11 and the lower disk 12 have the 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 disk 11 or the lower surface of the lower disk 12 may be covered with the enamel layer.

[0086] 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 disk 11 is in a high-temperature heat storage state. If more heat of the upper disk 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 disk 11 is covered with a far-infrared radiation structure (not shown in the drawings). In this way, more energy of the upper disk 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.

[0087] The far-infrared radiation structure is configured as an enamel layer. That is, the material used for the upper disk 11 in the enamel process is a far-infrared radiation enamel material. Of course, in other embodiments, ordinary enamel materials may also be used.

[0088] To enable the upper disk 11 to maintain a high temperature state, please refer to Figure 5 、 Figure 7 and Figure 11 , further, the first bracket 10 further includes a reflection structure 30 provided in the cavity 10a. The reflection structure 30 is used to reflect the heat transferred from the upper disk 11 to the cavity 10a upward, that is, back to the upper disk 11. Of course, in other embodiments, the reflection structure 30 may not be provided.

[0089] Optionally, the reflection structure 30 includes a reflection layer (not shown in the drawings) covering the upper surface of the lower plate 12. Specifically and optionally, the reflection layer is configured as a reflection coating, a reflection plating, 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. In this way, the structure is simple and easy to implement, and the weight of the pot support 101 will not be significantly increased.

[0090] Furthermore, the reflection structure 30 further includes a reflector 31 disposed in the cavity 10a, and the reflector 31 is spaced above the reflection layer. That is to say, the reflector 31 plays a main reflection role to directly reflect the heat in the cavity 10a back to the upper plate 11, while the reflection layer located below the reflector 31 can make the heat in the cavity 10a gather on the reflector 31 as much as possible. In this way, the reflector 31 and the reflection layer constitute a multiple reflection effect, which can improve the overall reflection effect of the reflection structure 30. 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 reflection layer, such as the reflection layer is a zinc layer, that is to say, the reflector 31 is configured as a galvanized sheet.

[0091] Of course, in other embodiments, it may also be that only the reflector 31 is provided without the reflection layer, and optionally, at least two reflectors 31 are provided, and the at least two reflectors 31 are spaced apart in the up and down direction in the cavity 10a, as Figure 6 shown.

[0092] There are various installation methods of the reflector 31 in the cavity 10a. For example, please refer to Figure 5 and Figure 12 , in an embodiment, the lower support 40 includes a leg body 41 and a mounting table 42 provided on the leg body 41. The leg body 41 is provided on the lower surface of the lower plate 12, and the end of the mounting table 42 passes through the lower plate 12 and abuts against the lower side surface of the reflector 31. In this way, the lower support 40 plays a limiting and supporting role for the reflector 31, enabling the reflector 31 to be suspended above the lower plate 12, avoiding the obvious heat conduction problem caused by the direct contact between the reflector 31 and the lower plate 12, and thus reducing the heat dissipation degree of the reflector 31 and the upper plate 11.

[0093] In order 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 support plate 22. Of course, in other embodiments, the heat insulation pad may not be provided.

[0094] Please refer to Figure 5, in the embodiment where the pot support 101 is provided with a support structure 20, and the support structure 20 includes a support plate 22, optionally, the support plate 22 abuts against the upper side surface of the reflector 31. In this way, the support plate 22 and the mounting table 42 together realize the limiting installation of the reflector 31, and can improve the stability of the relative position of the reflector 31 in the cavity 10a.

[0095] Please refer to Figure 5 , Figure 11 and Figure 12 , 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.

[0096] Optionally, the first fastener 61 is configured as a bolt, and the support plate 22 is correspondingly provided with a first mounting hole 223, and the first fastener 61 is locked in the first mounting hole 223. Specifically, first install the lower support 40 on the lower plate 12, then the reflector 31 is sleeved on the mounting table 42 of the lower support 40 through the limiting hole 311, then cover the upper plate 11 and the support structure 20 pre-fixed on the upper plate 11 together on the lower plate 12, and finally pass the first fastener 61 through the mounting table 42 and connect 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. In this way, the structure is simple and convenient for installation.

[0097] Of course, the structural form and installation method of the first fastener 61 are not limited to this. In other embodiments, the first fastener 61 can also be configured as a rivet or a buckle, etc.

[0098] 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 through the first fastener 61, rather than the form of welding the reflector 31 to the upper plate 11, therefore, the reflector 31 will not follow the upper plate 11 to perform the enamel process together, and can avoid the problem that the reflector 31 turns black due to the high-temperature environment conditions of the enamel process and causes the reflection performance to fail.

[0099] Please refer to Figure 5 , Figure 7 and Figure 12, optionally, the pot support 101 further includes a second fastener 62. The foot body 41 is provided with a second mounting hole 411, and the lower plate 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 define 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.

[0100] Please refer to Figures 14 to 16 , in another embodiment, the reflection structure 30 includes a reflection plate 31 disposed in the cavity 10a. The outer peripheral edge and / or the inner peripheral edge of the reflection plate 31 are provided with limiting pieces 313 corresponding to the annular gap 10b, and at least a part of the limiting pieces 313 extends into a partial area of the annular gap 10b in the circumferential direction. That is to say, the limiting part originally used to insert into the annular gap and maintain its shape is not provided on the support structure, but on the reflection plate. In this way, the reflection plate of this embodiment has two functional effects. It can not only reflect the heat transferred from the upper plate to the cavity back, but also maintain the effectiveness of the annular gap, thereby improving the problem of high heat dissipation rate of the upper plate in multiple aspects.

[0101] Specifically and optionally, the limiting pieces 313 include an outer limiting piece 314 provided on the outer peripheral edge of the plate body 312 and an inner limiting piece 315 provided on 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.

[0102] Please refer to Figures 14 to 16 , in another embodiment, further, the pot support 101 further includes a first fastener 61 and a support plate 22. The support plate 22 abuts against the upper surface of the reflection plate and is provided with a mounting hole corresponding to the first fastener 61. The first fastener 61 passes through the mounting table 42 and connects to the mounting hole. In this way, the structure is simple and the installation is reliable. Optionally, the edge of the support plate 22 is bent upwards towards the upper plate to form a fixed flange, and the fixed flange is welded and fixed to the upper plate. That is to say, the support plate 22 can be pre-welded to the upper plate to simplify the assembly process of the pot support 101.

[0103] Please refer to Figures 14 to 16, in another embodiment, optionally, in an embodiment where there are at least two reflecting plates, optionally, one of two adjacent reflecting plates 31 protrudes towards the other with a supporting convex portion 319, and the supporting convex portion 319 abuts against the other reflecting plate 31, so that a gap is formed between two opposite plate surfaces of two adjacent reflecting plates 31. In this way, the supporting convex portion 319 formed by the reflecting plate 31 itself is used to achieve the spacing effect, and the structure is simple and easy to implement. Of course, in other embodiments, a supporting member can also be additionally provided, for example, welding a supporting block on the plate surface of the reflecting plate 31.

[0104] Please refer to Figures 14 to 16 , in another embodiment, optionally, the supporting convex portion 319 includes a positioning flange bent out from the hole edge of the limiting hole 311. In this way, the positioning flange is formed by bending the hole edge of the limiting hole 311 to achieve the spacing effect between the plate surfaces of two adjacent reflecting plates 31, and the structure is simple and easy to implement. Of course, in other embodiments, the supporting convex portion can also be provided at other positions of the reflecting plate 31.

[0105] Please refer to Figures 14 to 16 , in another embodiment, optionally, the limiting hole 311 of the uppermost reflecting plate 31 also has an upwardly bent positioning flange, and the positioning flange abuts against the lower surface of the supporting plate 22. In this way, the positioning flange formed by the material originally located at the position of the limiting hole 311 is used to abut against the supporting plate 22, which can reduce the height dimension of the supporting plate 22, thereby reducing the material cost of the supporting plate 22 and lowering the manufacturing cost of the pot support 101.

[0106] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 , in an embodiment, the pot support 101 further includes a second support 70 and an upper support 50. The upper support 50 is provided at 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 guiding surface 70a arranged around the central hole 102. The guiding surface 70a is lower than the bearing surface 50a and is provided on one side of the top of the first support 10 close to the central hole 102.

[0107] In this way, by adding the second bracket 70 on the basis of the stove equipped with the first bracket 10, the first bracket 10 is arranged around the second bracket 70, and the second bracket 70 is arranged around the central hole 102, the flame generated by the burner of the stove can be enclosed in the second bracket 70, so that the heat of the flame generated by the burner is concentrated in the second bracket 70 to the greatest extent, so as to form a high-temperature zone in the area inside 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 smoke in the high-temperature zone play a major heating role on the cooker.

[0108] Specifically, the cooker is placed on the upper support 50 so that the bottom surface of the cooker is connected to the bearing surface 50a of the upper support 50. Since the height of the bearing surface 50a is higher than the guide surface 70a of the second bracket 70, there is a gap between the guide surface 70a and the bottom of the cooker. The high-temperature flue gas flows from the high-temperature area to the low-temperature area along the gap between the guide surface 70a and the bottom of the cooker, so that the high-temperature flue gas in the low-temperature area heats the cooker, and finally flows from the gap between the top of the upper plate 11 and the bottom of the cooker to the outside of the first bracket 10, so that the high-temperature flue gas and the cooker are fully exchanged with heat. In addition, 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 heat exchange with the cooker, so as to further improve the heating effect.

[0109] In this way, the high-temperature flue gas can fully exchange heat with the cooker, and then flow to the outside of the first bracket 10 through the gap between the top of the upper plate 11 and the bottom of the cooker, and accelerate the flow rate of the high-temperature flue gas to improve the convective heat exchange intensity between the high-temperature flue gas and the cooker.

[0110] See also Figure 5 It can be understood that the gap between the guide surface 70a and the bottom of the cooker, and the gap between the top of the upper plate 11 and the bottom of the cooker together constitute a smoke exhaust channel 103 for high-temperature smoke. In order to extend the residence time of the smoke in the smoke exhaust channel 103, thereby extending the heat exchange time between the smoke and the bottom of the cooker, optionally, the top of the upper plate 11 has a smoke exhaust surface 11a, which surrounds the outer circumference of the guide surface 70a and is spaced apart from the guide surface 70a in the radial direction of the central hole 102 to form a buffer gap 104.

[0111] 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 guide surface 70a of the second bracket 70, part of the airflow will be separated at the buffer gap 104, and vortex will be generated there, which can disrupt the originally smooth laminar flow of the high-temperature flue gas, which is conducive to prolonging the residence time of the high-temperature flue gas in the exhaust channel 103, thereby prolonging the heat exchange time between the high-temperature flue gas and the bottom of the cooker.

[0112] Please refer to Figure 5 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 disc 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. Thus, 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.

[0113] 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 the temperature it has is higher. 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. Thus, 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.

[0114] 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 materials may also be used.

[0115] The present utility model further provides a cooking appliance, which includes the aforementioned pot bracket. The specific structure of the pot bracket refers to the above embodiments. Since this cooking appliance adopts all the technical solutions of the above all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one.

Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
