[0043] The realization of the purpose, functional features and advantages of the present utility model will be further described with reference to the accompanying drawings in conjunction with the embodiments. Specific embodiments

[0044] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0045] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model, the directional indications are only used to explain the relative position 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 there are descriptions such as "first" and "second" in the embodiments of the present utility model, the descriptions of "first" and "second" are only for descriptive purposes and cannot be understood 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, solution B, or a solution that satisfies both A and B at the same time. In addition, the technical solutions between the 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 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 bracket usually 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.

[0048] In view of this, the present utility model provides a pot support.

[0049] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, the pot support includes:

[0050] A first support 10, the first support 10 having a cavity 10a; and

[0051] A reflection structure 30, the reflection structure 30 being disposed in the cavity 10a and configured to reflect the heat transferred from the upper sidewall of the first support 10 upward in the cavity 10a.

[0052] The technical solution of the present utility model can, by providing the reflection structure 30 in the cavity 10a, enable the heat to remain on the upper sidewall of the first support 10 (i.e., the area corresponding to the upper plate 11 in the prior art) as much as possible, and improve the problem of high heat dissipation rate of the upper plate 11, thereby improving the thermal efficiency of the cooking appliance.

[0053] Specifically and optionally, the reflection structure 30 includes a reflection plate provided in the cavity and / or a reflection layer provided on the lower cavity surface of the cavity.

[0054] Without loss of generality, the pot support 101 is usually disposed 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 pan, etc.). The first support 10 of the pot support 10 defines a central hole 102, and the central hole 102 is usually used to receive 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 spread area of the flame is relatively large, the flame will directly contact the upper sidewall of the first support 10 of the pot support 10 and transfer heat to the upper sidewall of the first support 10, resulting in the upper sidewall of the first support 10 being heated to a relatively high temperature. If the upper sidewall of the first support 10 is allowed to transfer heat downward to the air and the lower sidewall in the cavity 10a, part of the heat of the flame will continuously be transferred to the lower sidewall of the first support 10, the liquid receiving tray, and the cooking surface of the cooking appliance through this heat transfer path, which is not conducive to the cooking appliance maintaining a relatively high thermal efficiency level.

[0055] Furthermore, at least two reflection structures 30 are provided, and the at least two reflection structures 30 are spaced apart along the vertical direction. In this way, the uppermost reflection structure 30 plays a main reflection role to directly reflect the heat in the cavity 10a back to the upper sidewall of the first support 10, while the remaining reflection structures 30 can reflect as much heat as possible upward in the cavity 10a, and enable the uppermost reflection structure 30 to gather more heat and use the uppermost support reflection structure 30 to reflect more heat back to the upper sidewall of the first support 10. In this way, the at least two reflection structures 30 distributed along the vertical direction can constitute a multiple reflection effect, thereby enhancing the overall reflection effect of the reflection structure 30, reducing the heat dissipation rate of the upper sidewall of the first support 10, and further enhancing the thermal efficiency of the cooking appliance.

[0056] Please refer to Figure 2 、 Figure 5 and Figure 7 , optionally, the first bracket 10 includes an upper plate 11 and a lower plate 12 that are separately arranged, and a cavity 10a is formed at the splicing position of the upper plate 11 and the lower plate 12. In this embodiment, the upper side wall of the first bracket 10 is located on the upper plate 11, and the lower side wall of the first bracket 10 is located on the lower plate 12. In this way, it is convenient to install the reflector 31 in the cavity 10a. Of course, in other embodiments, the upper plate 11 and the lower plate 12 may also be integrally formed, for example, the first bracket 10 is manufactured by an extrusion molding process to form the cavity 10a together during manufacturing.

[0057] Please refer to Figure 5 , in one embodiment, the lowermost reflecting structure 30 is configured to cover a reflecting layer (not shown in the drawings) on the lower cavity surface of the cavity 10a. Specifically and optionally, the reflecting layer is configured as a reflecting coating, a reflecting plating layer, a reflecting deposition layer, or a polished mirror surface layer (i.e., a mirror surface 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 it will not significantly increase the weight of the pot bracket 101.

[0058] Please refer to Figure 5 , in one embodiment, optionally, at least one reflecting structure 30 is configured as a reflector 31, the reflector 31 is arranged above the reflecting layer, and a heat insulation gap is formed between the reflector 31 and the lower cavity wall of the cavity 10a. In this way, the heat insulation gap can prevent the reflector 31 from directly contacting the lower cavity wall of the cavity 10a (i.e., the lower side wall of the first bracket 10) and causing obvious heat conduction phenomenon, that is, prevent the reflector 31 from playing a heat conduction role between the upper side wall and the lower side wall of the first bracket 10, thereby further reducing the heat dissipation rate of the upper side wall of the first bracket 10.

[0059] Optionally, the surface of the reflector facing the upper cavity surface of the cavity is provided with a reflecting layer. In this way, the reflecting ability of the reflector can be improved.

[0060] Of course, the reflecting structure 30 is not limited to the above form. For example, please refer to Figure 6 , in another embodiment, at least two reflecting structures 30 are configured as reflectors 31, that is, at least two reflectors are arranged at intervals in the vertical direction. The pot bracket 101 further includes a mounting member provided on the first bracket 10, and the reflector 31 is mounted on the first bracket 10 through the mounting member. That is, there are a plurality of reflectors 31 distributed at intervals in the vertical direction in the cavity 10a, and these reflectors 31 are all mounted and fixed through the mounting member. In this way, the structure is simple and easy to install. Of course, in other embodiments, at least some of the reflectors 31 may also be directly fixed on the first bracket 10 by welding or the like.

[0061] Please refer to Figure 6 In another embodiment, optionally, one of two adjacent reflectors 31 protrudes towards the other with a support protrusion 312, and the support protrusion 312 abuts against the other reflector 31, so that a gap is formed between two opposite plate surfaces of the two adjacent reflectors 31. In this way, the support protrusion 312 formed by the reflector 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 31.

[0062] Of course, in other embodiments, the lowermost reflection structure 30 may also be configured as a reflection layer covering the lower cavity surface of the cavity 10a, and at least two reflectors 31 are further arranged at intervals above the reflection layer.

[0063] Optionally, the material of the reflector 31 is configured as metal, such as mirror stainless steel; or, a reflection layer is covered on the upper surface of the reflector 31, for example, the reflection layer is a zinc layer, that is, the reflector 31 is configured as a galvanized sheet.

[0064] In order to further reduce the heat dissipation rate of the upper platen 11, please refer to Figure 7 Optionally, the cavity 10a and the reflector 31 are arranged in a ring shape. In this way, the ring-shaped cavity 10a can achieve a good heat insulation effect, and at the same time, the ring-shaped reflector 31 can reflect more heat back to the upper platen 11. Of course, in other embodiments, there may also be multiple reflectors 31, and the multiple reflectors 31 are arranged at intervals along the circumferential direction of the central hole 102.

[0065] There are various structural forms of the reflector 31. For example, please refer to Figure 5 and Figure 11 In one embodiment, the reflector 31 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 first plate segment 31a is connected to the mounting member, and the second plate segment 31b extends obliquely upward in a direction away from the first plate segment 31a. That is, the cross-sectional shape of the reflector 31 is approximately U-shaped. In this way, the reflector 31 can correspond to more areas of the upper platen 11, and the reflected heat can be more concentrated in the middle of the top wall of the upper platen 11, increasing the temperature of the core area of the upper platen 11 and being beneficial to improving the thermal efficiency. Of course, in other embodiments, the reflector 31 with other structural forms may also be adopted, such as only providing the first plate segment 31a, or only providing one first plate segment 31a and one second plate segment 31b.

[0066] Please refer to Figure 5 and Figure 12, optionally, the mounting member includes a lower support 40, the lower support 40 includes a foot body 41 and a mounting table 42 provided on the foot body 41, the foot body 41 protrudes from the lower surface of the first bracket 10, and the end of the mounting table 42 penetrates into the cavity 10a, and the emission plate 31 is mounted on the mounting table 42. In this way, the structure is simple and easy to implement.

[0067] Optionally, the end of the mounting table 42 passes through the first bracket 10 and abuts against the lowermost reflecting plate 31. It can be understood that the lower support 40 is used to suspend the first bracket 10 above the liquid storage tray to prevent the first bracket 10 from directly contacting the liquid storage tray. The lower support 40 plays a role in limiting and supporting the lowermost reflecting plate 31 to realize the suspended installation of the reflecting plate 31 relative to the lower plate 12, which can simplify the structure of the pot bracket 101. Of course, in other embodiments, other methods can also be used to realize the suspended installation of the reflecting plate 31.

[0068] Please refer to Figure 5 and Figure 11 , optionally, the reflecting plate 31 is provided with a limiting hole 311, the side wall surface of the mounting table 42 is provided with a step portion 421 corresponding to the limiting hole 311, the hole edge of the limiting hole 311 abuts against the step portion 421, and the supporting convex portion 312 includes a supporting flange bent out from the hole edge of the limiting hole 311. In this way, through the mutual cooperation of the limiting hole 311 and the step portion 421, the installation of the reflecting plate 31 can be made more stable. Secondly, the supporting flange is formed by bending the hole edge of the limiting hole 311, and the interval effect between the plate surfaces of two adjacent reflecting plates 31 is realized. 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.

[0069] Please refer to Figure 5 and Figure 7 , optionally, the mounting member further includes a support plate 22, the support plate 22 is provided on the upper side wall of the first bracket 10, and abuts against the upper end of the mounting table 42 and / or the reflecting plate 31. In this way, through the cooperation of the support plate 22 and the lower support 40, the limiting installation of the reflecting plate 31 can be realized, and the stability of the relative position of the reflecting plate 31 in the cavity 10a can be improved. Of course, in other embodiments, the support plate 22 may not be provided.

[0070] In order to further improve the heat conduction problem between the support structure 20 and the lower plate 12, further, the pot bracket 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.

[0071] Please refer to Figure 2 , Figure 5 and Figure 13, the first bracket 10 includes a separately provided upper plate 11 and a lower plate 12. The support plate 22 is provided on the upper plate 11, and the lower support 40 is provided on the lower plate 12. The reflector 31 is sleeved and supported on the stepped portion 421, and the support plate 22 abuts against and restricts the reflector 31 from top to bottom. That is, when the support plate 22 follows the assembly action of the upper plate 11 to abut the reflector 31 against the mounting table 42, the limit installation of the reflector 31 can be achieved. In this way, it is convenient to install and fix the reflector 31 on the first bracket 10.

[0072] 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 peripheral edge and the inner peripheral edge. That is, 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. In this way, 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 peripheral edge, or only the upper plate 11 and the lower plate 12 have an annular gap 10b at the relative positions of the inner peripheral edge.

[0073] Please refer to Figure 5 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 far 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 perspective (i.e., the top view angle) or the side perspective (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.

[0074] Of course, in some other embodiments, it may also be that 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 the interval between the plate surface of the upper plate 111 and the side edge of the lower plate 12 in the up and down direction.

[0075] Please refer to Figure 5 and Figure 10, optionally, the lower plate 12 includes a lower plate body 121, a lower outward flange 122 bent upward from the outer peripheral edge of the lower plate body 121, and a lower inward flange 123 bent upward from the inner peripheral edge of the lower plate body 121. The lower outward flange 122 is located on the side of the upper outward flange 112 close to the central hole 102 and is disposed opposite to the upper outward flange 112 to form an outer ring gap 10c at an interval; the lower inward flange 123 is located on the side of the upper inward flange 113 away from the central hole 102 and is disposed opposite to the upper inward flange 113 to form an inner ring gap 10d at an interval. In this way, the structure is simple and easy to implement. Of course, in other embodiments, the lower outward flange 122 and the lower inward flange 123 may not be provided, and the plate surfaces of the upper plate body 111 and the lower plate body 121 form an annular gap 10b at an interval in the up and down direction.

[0076] Please refer to Figure 5 and Figure 8 , further, the inner and outer edges 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 outward flange 112, and the other limiting flange 221 is provided on the inner wall surface of the upper inward flange 113. In this way, the limiting flanges 221 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 are relatively offset and cause a tendency of the annular gap 10b to change, the limiting flanges 221 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, which is conducive to retaining heat in the upper plate 11 as much as possible. Of course, in other embodiments, the limiting flanges 221 may not be provided.

[0077] There are various ways to fix the limiting flanges 221 to the upper plate 11. For example, in one embodiment, the limiting flanges 221 are fixed to the upper outward flange 112 and / or the upper inward flange 113 by welding. In this way, it can not only improve the connection strength between the limiting flanges 221 and the upper plate 11, simplify the structure of the pot bracket 101, but also limit the welding marks generated during welding to the area of the upper plate 11 corresponding to the limiting flanges 221, that is, limit the welding marks to the upper outward flange 112 and the upper inward flange 113. Since the upper outward flange 112 and the upper inward 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.

[0078] It should be noted that the height visible area of the pot bracket 101 refers to its visual area from a top view. Correspondingly, the remaining areas outside the height visible area are non-height visible areas.

[0079] 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 fixed by welding.

[0080] Please refer to Figure 5 and Figure 7 , further, the first bracket 10 further includes a first fastener 61, and the support plate is fixed to the mounting table 42 by the first fastener 61. In this way, the structure is simple and easy to implement.

[0081] Optionally, the support plate 22 is provided with a first mounting hole 223 corresponding to the first fastener 61, and the first fastener 61 passes through the mounting table 42 and is connected to the first mounting hole 223. In this way, the structure is simple and the installation is reliable. Optionally, the first fastener 61 is configured as a bolt, and the first fastener 61 is locked in the first mounting hole 223. In this way, the structure is simple and convenient for installation.

[0082] In the embodiment where the pot bracket 101 has the lower support 40 and the support plate 22, the assembly process of the pot bracket 101 includes: first, the lower support 40 is installed 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, and then the upper plate 11 and the support plate 22 pre-fixed on the upper plate 11 are covered together on the lower plate 12. Finally, the first fastener 61 passes through the mounting table 42 and is connected to the support plate 22. 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 bracket 101 of the technical solution of the present invention is relatively convenient and fast, thereby improving production efficiency.

[0083] 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, rather than the form of welding the reflector 31 to the upper plate 11, therefore, the reflector 31 will not undergo the enameling process together with the upper plate 11, and the problem that the reflector 31 turns black due to the high-temperature environment conditions of the enameling process and the reflection performance fails can be avoided.

[0084] Please refer to Figure 5 and Figure 12Optionally, the pot support 101 further includes a second fastener 62, the support body 41 is provided with a second mounting hole 411, the lower plate 12 is provided with a mounting hole 124 corresponding to the second mounting hole 411, and the second fastener 62 penetrates the mounting 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 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.

[0085] See also Figure 1 , Figure 5 and Figure 7 In one embodiment, the pot support 101 further includes a second support 70 and an upper support 50, the upper support 50 is arranged 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 heated component, the top of the second support 70 has a guide surface 70a arranged around the central hole 102, the guide surface 70a is lower than the bearing surface 50a, and is arranged on one side of the top of the first support 10 close to the central hole 102.

[0086] 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.

[0087] 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.

[0088] In this way, after the high-temperature flue gas can fully exchange heat with the cooking utensil, it then flows through the gap between the top of the upper plate 11 and the bottom of the cooking utensil to the outside of the first bracket 10, and the flow rate of the high-temperature flue gas is increased to enhance the convective heat transfer intensity between the high-temperature flue gas and the cooking utensil.

[0089] Please refer to Figure 5 , it can be understood that the gap between the guide 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 form the smoke exhaust passage 103 for the high-temperature flue gas. In order to extend the residence time of the flue gas in the smoke exhaust passage 103, thereby prolonging 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 guide surface 70a and is spaced from the guide surface 70a in the radial direction of the central hole 102 to form a buffer gap 104.

[0090] 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, a phenomenon of partial air flow detachment will occur at the buffer gap 104, and vortices will be generated here, which can disrupt the originally smooth laminar flow of the high-temperature flue gas, facilitating the extension of the residence time of the high-temperature flue gas in the smoke exhaust passage 103, thereby prolonging the heat exchange duration between the high-temperature flue gas and the bottom of the cooking utensil.

[0091] Please refer to Figure 5 , optionally, the height of the smoke exhaust surface 11a is higher than that of the guide surface 70a, and the upper surface of the upper plate 11 also has a guiding surface 11b connected to the inner circumference of the smoke exhaust surface 11a. The guiding surface 11b extends downward obliquely in the direction close to the central hole 102, and a buffer cavity 105 is formed between the guiding surface 11b and the second bracket 70 at an interval. 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 vortices at the buffer gap 104 for the high-temperature flue gas, thereby further extending the residence time of the high-temperature flue gas in the smoke exhaust passage 103.
