[0002] In the prior art, a pot support generally includes a spliced upper plate and a lower plate. The side edges of the upper plate and the lower plate are fixedly spliced 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 transferred to the lower plate through the air in the cavity, resulting in a relatively high heat dissipation rate of the upper plate. Summary of the Utility Model

[0041] 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. Detailed implementation manners

[0042] 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 making creative efforts belong to the scope of protection of the present utility model.

[0043] 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.

[0044] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. 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 where A and B are satisfied simultaneously. In addition, the technical solutions between the 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.

[0045] In the prior art, a pot support generally includes an upper plate and a lower plate spliced together. The side edges of the upper plate and the lower plate are fixedly spliced 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 transferred to the lower plate through the air in the cavity, resulting in a relatively high heat dissipation rate of the upper plate.

[0046] In view of this, the present utility model proposes a pot support.

[0047] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, the pot support includes:

[0048] A first support 10, the first support 10 having a cavity 10a; and

[0049] A reflecting plate 31, the reflecting plate 31 being disposed in the cavity 10a and configured to reflect the heat transferred from the upper side wall of the first support 10 upward into the cavity 10a, and an insulation gap is formed between the reflecting plate 31 and the lower side wall of the first support 10.

[0050] Without loss of generality, the pot support 101 is usually placed 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.). The first support 10 of the pot support 101 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 spreading area of the flame is relatively large, the flame will directly contact the upper side wall of the first support 10 of the pot support 101 and transfer heat to the upper side wall of the first support 10, resulting in the upper side wall of the first support 10 being heated to a relatively high temperature. If the upper side wall of the first support 10 is allowed to transfer heat downward to the air and the lower side wall in the cavity 10a, part of the heat of the flame will continuously be transferred to the lower side wall 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 maintaining a relatively high thermal efficiency level of the cooking appliance.

[0051] The technical solution of the present utility model can reduce the heat dissipation rate of the upper side wall of the first support 10 and retain the heat in the upper side wall of the first support 10 as much as possible by providing the reflecting plate 31 in the cavity 10a, thereby improving the thermal efficiency of the cooking appliance. Secondly, an insulation gap is formed between the reflecting plate 31 and the lower side wall of the first support 10, which can prevent the reflecting plate 31 from directly contacting the lower plate 12 and causing obvious heat conduction, that is, preventing the reflecting plate 31 from playing a heat conduction role between the upper side wall and the lower side wall of the first support 10, thereby further reducing the heat dissipation rate of the upper side wall of the first support 10.

[0052] Please refer to Figure 1 and Figure 5, optionally, the first bracket 10 includes a separately arranged upper plate 11 and a lower plate 12, 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.

[0053] Optionally, the material of the reflector 31 is configured as metal, such as mirror stainless steel; or, the upper surface of the reflector 31 is covered with a reflective coating, for example, the reflective coating is a zinc layer, that is, the reflector 31 is configured as a galvanized sheet.

[0054] To further reduce the heat dissipation rate of the upper plate 11, please refer to Figure 7 , Figure 11 , 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 plate 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.

[0055] It can be understood that the number of reflectors 31 can be only one, as shown in Figure 5 , or there can be multiple, as shown in Figure 6 .

[0056] 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. In this way, the structure is simple and easy to install. Of course, in other embodiments, the reflector 31 may also be directly fixed on the first bracket 10 by welding or other means.

[0057] 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 segments 31b extend obliquely upward away from the first plate segment 31a. That is, the cross-sectional shape of the reflector 31 is generally U-shaped. In this way, the reflector 31 can correspond to more areas of the upper plate 11, and the reflected heat can be more concentrated in the middle of the top wall of the upper plate 11, improving the temperature of the core area of the upper plate 11 and being beneficial to improving the thermal efficiency. Of course, in other embodiments, the reflector 31 with other structural forms can also be used, such as only setting the first plate segment 31a, or only setting one first plate segment 31a and one second plate segment 31b.

[0058] Please refer to Figure 5 and Figure 12 , optionally, the mounting member includes a lower support 40. The lower support 40 includes a support leg body 41 and a mounting table 42 provided on the support leg body 41. The support leg body 41 protrudes from the lower surface of the first bracket 10, and the end of the mounting table 42 passes through the first bracket 10 and abuts against the lower side surface of the reflector 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 of limiting and supporting the reflector 31 to realize the suspended installation of the reflector 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 reflector 31.

[0059] Please refer to Figure 5 , Figure 8 and Figure 13 , 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 side surface of the reflector 31. In this way, the support plate 22 and the lower support 40 together realize the limiting installation of the reflector 31, which can improve the stability of the relative position of the reflector 31 in the cavity 10a. Of course, in other embodiments, the support plate 22 may not be provided.

[0060] 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 is provided on the side wall surface of the mounting table 42 corresponding to the limiting hole 311. 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.

[0061] Please refer to Figure 2 and Figure 5, optionally, 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, the support plate 22 follows the assembly movement of the upper plate 11 to abut the reflector 31 against the mounting table 42, and 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.

[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, 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. 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 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.

[0063] Please refer to Figure 5 and Figure 9 , optionally, the upper plate 11 includes an upper plate body 111, an upper outer flange 112 bent downward from the outer periphery of the upper plate body 111, and an upper inner flange 113 bent downward from the inner periphery of the upper plate body 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 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.

[0064] 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 some 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 body 111 and the side edge of the lower plate 12 in the vertical direction.

[0065] Please refer to 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 disposed opposite to the upper outer flange 112 to form an outer ring gap 10c therebetween at an interval; 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 therebetween at an interval. 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 an interval between the plate surface of the upper plate body 111 and the plate surface of the lower plate body 121 in the up-down direction.

[0066] Please refer to Figure 5 and Figure 8 , further, the inner side edge and the outer side edge of the support plate 22 are bent downward to form limiting flanges 221 in the radial direction of the first bracket 10. One limiting flange 221 is disposed on the inner wall surface of the upper outer flange 112, and the other limiting flange 221 is disposed on the inner wall surface of the upper inner 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 their large-area direct contact, thereby facilitating keeping the heat in the upper plate 11 as much as possible. Of course, in other embodiments, the limiting flanges 221 may not be provided.

[0067] 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 outer flange 112 and / or the upper inner flange 113 by welding. In this way, not only can the connection strength between the limiting flanges 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 flanges 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.

[0068] 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 the non-height visible areas.

[0069] 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.

[0070] Please refer to Figure 5 and Figure 7 , the first bracket 10 further includes a first fastener 61. The support plate 22 is provided with a first mounting hole 223 corresponding to the first fastener 61. 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 to the first mounting hole 223. In this way, the structure is simple and convenient for installation.

[0071] 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, 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, 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 the production efficiency.

[0072] 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 be subjected to the enamel 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 enamel process and the reflection performance fails can be avoided.

[0073] Please refer to Figure 5 , Figure 7 and Figure 12 , optionally, the pot bracket 101 further includes a second fastener 62. The leg body 41 is provided with a second mounting hole 411, and the lower plate 12 is 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 install 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.

[0074] Please refer toFigure 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 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.

[0075] Thus, by adding the second support 70 on the basis of the cooking appliance configured with the first support 10, making the first support 10 disposed around the second support 70 and making the second support 70 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, forming 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.

[0076] 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 that of 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 sufficiently. Moreover, since the flame of the burner and the high-temperature flue gas generated by the burner heat the top of the second support 70, the top of the second support 70 can also play a role in heat exchange with the cooking utensil to further improve the heating effect.

[0077] Thus, after the high-temperature flue gas exchanges heat with the cooking utensil sufficiently, 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 enhance the convective heat transfer intensity between the high-temperature flue gas and the cooking utensil.

[0078] 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 form the smoke exhaust passage 103 for high-temperature flue gas. In order to extend the residence time of the flue gas in the smoke exhaust passage 103, thereby extending the heat exchange time 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 diversion surface 70a and is spaced apart from the diversion surface 70a in the radial direction of the central hole 102 to form a buffer gap 104.

[0079] 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 diversion surface 70a of the second bracket 70, a phenomenon of partial air flow detachment will occur at the buffer gap 104, and eddy currents will be generated here, which can disrupt the 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, thereby extending the heat exchange time between the high-temperature flue gas and the bottom of the cooking utensil.

[0080] Please refer to Figure 5 , optionally, the height of the smoke exhaust surface 11a is higher than that of the diversion 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 along the direction close to the central hole 102. The guiding surface 11b and the second bracket 70 are spaced apart to form a buffer cavity 105, 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.
