The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0066] Please refer to Figure 1 to Figure 2 The present application proposes a stove 1000. In the embodiment of the present application, the stove 1000 includes a pot rack 100 and a burner 200. The pot rack 100 is used to be placed on a stove (not shown in the figure) and to support the pot 2000 to prevent the pot 2000 from sliding or tipping over during the heating process, reduce the occurrence of accidental injuries, and ensure the stability of the cooking process. In addition, the pot rack 100 surrounds the outer side of the burner 200 and forms a combustion chamber 10a. In this way, the flame generated by the burner 200 during the working process will pass through the combustion chamber 10a to contact the bottom of the pot 2000 to achieve heating of the pot 2000. In addition, under the surrounding arrangement of the pot rack 100, the heat of the burner 200 can be concentrated and transferred in the direction of the pot 2000, preventing the heat from leaking out, so that the heat of the burner 200 can fully act on the pot 2000.

[0067] In order to improve the combustion efficiency of the burner 200 by means of the pot support 100, please refer to Figure 3 to Figure 4Specifically, the pot rack 100 may include a pot rack body 10 and a perforated heat exchanger 13 .

[0068] The pot support body 10 is arranged in an annular shape, for example, it can be arranged in a circular ring shape, an elliptical ring shape or a square ring shape, and the pot support body 10 can be made of cast iron, enamel or galvanized materials with advantages of high temperature resistance and good strength. The pot support body 10 surrounds the outer side of the burner 200, and the inner side is surrounded by the above-mentioned combustion chamber 10a.

[0069] The hole-punched heat exchanger 13 may be arranged in an annular shape, for example, in a circular ring shape, an elliptical ring shape, or a square ring shape, and the material of the hole-punched heat exchanger 13 may be a metal material with good thermal conductivity, such as copper or aluminum, which is not limited in this embodiment. The hole-punched heat exchanger 13 is arranged at the bottom 102 of the pot rack body 10. It is understood that during the operation of the burner 200, the heat radiation generated by the flame generated by the burner 200 will act on the pot rack body 10 surrounding the outside of the burner 200, and indirectly heat the pot rack body 10. Furthermore, the heat on the pot rack body 10 will also exchange heat with the hole-punched heat exchanger 13 in a heat exchange manner, thereby increasing the temperature of the hole-punched heat exchanger 13.

[0070] It can be understood that the secondary air can enter the combustion chamber 10a through the bottom 102 of the pot rack body 10 to supplement the flame of the burner 200 so that the flame burns fully. Therefore, in the process of the secondary air entering the combustion chamber 10a from the bottom 102 of the pot rack body 10, the secondary air can exchange heat with the perforated heat exchanger 13 to increase its own temperature. In this way, the secondary air can be preheated through the perforated heat exchanger 13 before it supplements the flame of the burner 200.

[0071] The hole-punched heat exchanger 13 is disposed at the bottom 102 of the pot rack body 10 and can include the following two types: first, the hole-punched heat exchanger 13 is directly connected to the bottom 102 of the pot rack body 10 to realize that the hole-punched heat exchanger 13 is disposed at the bottom 102 of the pot rack body 10; second, the hole-punched heat exchanger 13 is indirectly connected to the pot rack body 10 through an additionally disposed connecting member, and the hole-punched heat exchanger 13 can be located at the bottom 102 of the pot rack body 10, so that the hole-punched heat exchanger 13 can also be disposed at the bottom 102 of the pot rack body 10, and this embodiment does not impose any limitation on this.

[0072] The hole-drilled heat exchanger 13 has a heat exchange hole 13a, wherein the secondary air can flow into the combustion chamber 10a after heat exchange with the wall surface of the heat exchange hole 13a.

[0073] Among them, the heat exchange channel 13a is in a straight line shape, and the straight line channel design can make the flow path of the secondary air more direct and simple. Of course, in other embodiments, the heat exchange channel 13a can also be in an arc shape, and the arc-shaped heat exchange channel 13a can increase the turbulence of the secondary air, so that the secondary air contacts the wall of the heat exchange channel 13a more frequently, so as to increase the heat exchange between the secondary air and the wall of the heat exchange channel 13a, thereby enhancing the heat exchange efficiency of the two.

[0074] The flow cross-sectional shape of the heat exchange channel 13a includes a circle, an ellipse, a square, a rhombus, a triangle or a strip, so that the fluid cross-sectional shape of the heat exchange channel 13a is relatively regular, which is convenient for the workshop to manufacture the heat exchange channel 13a.

[0075] In actual use, both the outer ring fire cover and the inner ring fire cover of the burner 200 are arranged in a circular ring shape, and the multiple fire outlet holes on the outer ring fire cover and the inner ring fire cover are arranged at intervals along the circumference, so the secondary air will flow in at various positions along the circumference of the pot rack 100 to correspond to the positions of the multiple fire outlet holes. Based on this, the present embodiment sets the number of heat exchange channels 13a to be multiple, and the multiple heat exchange channels 13a are arranged at intervals along the circumference of the pot rack body 10, so that the secondary air at various positions along the circumference of the pot rack 100 can exchange heat with the heat exchange channels 13a, thereby improving the uniformity of the secondary air supplementing the flame of the burner 200.

[0076] In summary, in this embodiment, a perforated heat exchanger 13 is provided at the bottom 102 of the pot rack body 10, and the perforated heat exchanger 13 has a plurality of heat exchange channels 13a, so that the pot rack 100 of this embodiment has at least the following technical effects:

[0077] The heat exchange channel 13a is used to exchange heat with the secondary air to preheat the secondary air. In this way, firstly, the heat radiated by the flame to the pot rack body 10 can be brought back to the combustion chamber 10a through the secondary air to supplement the flame, thereby realizing heat recovery and improving the combustion efficiency of the burner 200 of the stove 1000; secondly, the temperature of the pot rack body 10 can be reduced by the perforated heat exchanger 13, effectively improving the high-temperature ablation phenomenon of the pot rack body 10; furthermore, the supplementary effect of the secondary air on the flame of the burner 200 can be effectively improved, so that the carbon monoxide generated by the burner 200 during operation can be better converted into carbon dioxide, reducing the emission of smoke to ensure the health safety of users.

[0078] Please refer to Figure 3 to Figure 4 In some embodiments, the connection method between the hole heat exchanger 13 and the pot rack body 10 includes at least one of welding, riveting, threaded connection, clamping and interference fit.

[0079] It can be understood that in the present embodiment, the hole-digging heat exchanger 13 and the pot rack body 10 are split structures, so the hole-digging heat exchanger 13 and the pot rack body 10 can be manufactured separately, which is convenient for manufacturing and molding, and it is also convenient to improve the manufacturing accuracy of the hole-digging heat exchanger 13 and the pot rack body 10. After molding, the two are connected. For example, any one of the above connection methods can be adopted, such as welding or riveting, which is more firmly connected. For example, a combination of multiple connection methods can be adopted, such as through the combination of snap-fit ​​and threaded connection, or through the combination of interference fit and snap-fit, which can further improve the stability of the connection between the hole-digging heat exchanger 13 and the pot rack body 10.

[0080] In an exemplary embodiment, when the connection mode between the hole-punched heat exchanger 13 and the pot rack body 10 is threaded connection, the pot rack 100 further includes a locking member, wherein the hole-punched heat exchanger 13 is provided with a first threaded hole, the pot rack body 10 is provided with a second threaded hole, and the locking member is sequentially penetrated through the first threaded hole and the second threaded hole to realize the threaded connection between the hole-punched heat exchanger 13 and the pot rack body 10. In another exemplary embodiment, when the connection mode between the hole-punched heat exchanger 13 and the pot rack body 10 is snap connection, the hole-punched heat exchanger 13 is provided with a snap buckle, and correspondingly, the pot rack body 10 is provided with a snap groove that is snap-fitted with the snap buckle.

[0081] In other embodiments, the perforated heat exchanger 13 and the pot rack body 10 may be an integral structure, and the perforated heat exchanger 13 and the pot rack body 10 may be directly manufactured by stamping, which can reduce the assembly steps of the two, and this embodiment does not limit this.

[0082] Please refer to Figure 3 to Figure 4 In some embodiments, the hole-punched heat exchanger 13 includes a first heat exchange portion 133 and a second heat exchange portion 134. The shapes of the first heat exchange portion 133 and the second heat exchange portion 134 can be circular, oval or square, and the shapes of the two match each other, so that the integrity of the hole-punched heat exchanger 13 can be better. The materials of the first heat exchange portion 133 and the second heat exchange portion 134 can be metal materials with good thermal conductivity such as copper and aluminum, and this embodiment does not limit this.

[0083] The first heat exchange part 133 and the second heat exchange part 134 are separately provided, so that the first heat exchange part 133 and the second heat exchange part 134 can be manufactured separately, which is convenient for manufacturing and molding, and also convenient for improving the high manufacturing accuracy of the first heat exchange part 133 and the second heat exchange part 134. After molding, the two are connected, and the connection method of the two may include welding, threaded connection or clamping, etc. In other embodiments, the first heat exchange part 133 and the second heat exchange part 134 can also be integrally provided, and this embodiment does not limit this.

[0084] The first heat exchange portion 133 is disposed at the bottom 102 of the pot rack body 10. For example, the first heat exchange portion 133 is directly connected to the bottom 102 of the pot rack body 10 to achieve that the first heat exchange portion 133 is disposed at the bottom 102 of the pot rack body 10. Alternatively, the first heat exchange portion 133 is indirectly connected to the pot rack body 10 through an additionally provided connecting member, and the first heat exchange portion 133 can be located at the bottom 102 of the pot rack body 10. In this way, the first heat exchange portion 133 can also be disposed at the bottom 102 of the pot rack body 10. This embodiment does not limit this.

[0085] The second heat exchange part 134 is connected to the side of the first heat exchange part 133 away from the second heat exchange part 134, and cooperates with the first heat exchange part 133 to form a heat exchange channel 13a. In this way, the form of the heat exchange channel 13a formed by the cooperation of the two can avoid the situation that the heat exchange channel 13a is formed by a single component and the self-strength is insufficient, compared with the form of the heat exchange channel 13a formed by the first heat exchange part 133 or the second heat exchange part 134 alone. Moreover, after the first heat exchange part 133 and the second heat exchange part 134 are manufactured separately, the two can be connected to form the heat exchange channel 13a, which is convenient for manufacturing. Of course, the heat exchange channel 13a can also be formed by the first heat exchange part 133 or the second heat exchange part 134 alone, and this embodiment does not limit this.

[0086] Please continue to refer to Figure 3 to Figure 4 Furthermore, the first heat exchange part 133 and the second heat exchange part 134 can be arranged in a ring shape, such as a circular ring shape, an elliptical ring shape or a square ring shape, and the shapes of the two match each other, so that the integrity of the hole heat exchanger 13 is better.

[0087] The surface of the first heat exchange part 133 facing the second heat exchange part 134 has a plurality of first holes 133a, and the surface of the second heat exchange part 134 facing the first heat exchange part 133 has a plurality of second holes 134a. After the first heat exchange part 133 and the second heat exchange part 134 are connected, the first holes 133a and the second holes 134a are connected one by one to form a heat exchange channel 13a. In this way, the first holes 133a of the heat exchange channel 13a are formed by the first heat exchange part 133, and the second holes 134a of the heat exchange channel 13a are formed by the second heat exchange part 134, which can avoid the situation that a large-sized channel is formed by a single component and the self-strength is insufficient. In addition, through the cooperation of the first holes 133a and the second holes 134a, a heat exchange channel 13a with a more complex shape and structure and a special structure can be formed.

[0088] Of course, in other embodiments, the first heat exchange part 133 may form a first hole 133a with an opening on the surface facing the second heat exchange part 134, the second heat exchange part 134 may be connected to the first heat exchange part 133, and the opening may be sealed on the surface facing the first heat exchange part 133 to cooperate with the first hole 133a to form a heat exchange channel 13a, or the second heat exchange part 134 may form a second hole 134a with an opening on the surface facing the first heat exchange part 133, the first heat exchange part 133 may be connected to the second heat exchange part 134, and the opening may be sealed on the surface facing the second heat exchange part 134 to cooperate with the second hole 134a to form a heat exchange channel 13a, and this embodiment does not impose any restrictions on this.

[0089] See also Figure 4 In some embodiments, the pot rack 100 further includes support legs 60 fixedly connected to the pot rack body 10, and the support legs 60 are used to be placed on the stove to support the pot rack body 10, so as to set the pot rack body 10 on the stove.

[0090] There are multiple supporting legs 60 , which are arranged at intervals on the bottom 102 of the pot rack body 10 along the circumference of the pot rack 100 . In this way, the supporting effect of the pot rack body 10 can be improved by the multiple supporting legs 60 along the circumference of the pot rack 100 .

[0091] The hole-punched heat exchanger also includes a connecting portion 135, which is connected to the second heat exchange portion 134 and has a first connecting hole 13c. The supporting leg 60 has a second connecting hole 60a. The pot rack 100 also includes a fastener, which is sequentially passed through the first connecting hole 13c and the second connecting hole 60a to fix the hole-punched heat exchanger 13 to the supporting leg 60.

[0092] It is understandable that the fastener can be a threaded connector, and the first connection hole 13c and the second connection hole 60a are corresponding threaded holes. In this way, the structural connection based on the threaded connection method is stable and can have good repeated disassembly and assembly performance.

[0093] In other embodiments, a buckle is provided on the connection portion 135, and a buckle groove that engages with the buckle is provided on the support leg 60, so that a fixed connection between the hole heat exchanger 13 and the support leg 60 can be achieved, which is not limited in this embodiment.

[0094] Please refer to Figures 3 to 5In some embodiments, the pot support body 10 has an outer side surface 104 disposed away from the combustion chamber 10a, and the pot support 100 further includes an outer heat insulating portion 80, which may be substantially in the form of a cover body, so that the outer heat insulating portion 80 wraps the outer side surface 104. The outer heat insulating portion 80 is connected to the pot support body 10 and is connected to the outer side of the first heat exchange portion 133, so that the first heat exchange portion 133 can be indirectly connected to the pot support body 10 through the outer heat insulating portion 80.

[0095] It is understandable that the heat of the flame generated by the burner 200 will leak outward. Based on this problem, the present embodiment wraps the outer heat insulation part 80 on the outer side surface 104 to prevent the heat from leaking outward, so that the heat can be concentrated and transferred toward the cookware 2000, so that the heat of the burner 200 can fully act on the cookware 2000, thereby improving the cooking heating effect. At the same time, when the secondary air flows to the heat exchange channel 13a through the outer heat insulation part 80, the outer heat insulation part 80 can also have a certain preheating effect on the secondary air.

[0096] Please refer to Figures 3 to 5 Furthermore, the pot support body 10 includes a baffle ring 107, and the baffle ring 107 has an inner side 103 facing the combustion chamber 10a. It can be understood that during the actual use of the stove 1000, the burner 200 will generate a certain amount of smoke, and there is a certain probability that this part of the smoke will interfere with the secondary air flowing out through the heat exchange channel 13a, affecting the supplement of the secondary air. In order to solve this technical problem, the baffle ring 107 is provided to block the smoke and reduce the degree of interference of the smoke with the supplement of the secondary air.

[0097] The pot rack 100 also includes an inner heat insulating portion 90, which can be roughly cylindrical, wherein the inner heat insulating portion 90 is connected to the inner side of the first heat exchange portion 133, so that the first heat exchange portion 133 can be indirectly connected to the pot rack body 10 through the outer heat insulating portion 80, and can also be indirectly connected to the pot rack body 10 through the inner heat insulating portion 90, and the connection is more secure.

[0098] The inner insulation part 90 is arranged opposite to the inner side surface 103 of the baffle ring 107. In this way, the inner insulation part 90 can block the heat from being transferred from the combustion chamber 10a to the baffle ring 107, thereby preventing the heat from leaking out. Moreover, the double-layer insulation cooperation between the outer insulation part 80 and the inner insulation part 90 can greatly improve the effect of preventing the heat from leaking out. In addition, the surface of the inner insulation part 90 facing away from the baffle ring 107 is at least partially formed as a guide surface. On the basis of the upward protrusion of the inner insulation part 90, the secondary air can be guided by the guide surface to flow to the fire outlet of the outer ring fire cover of the burner 200, so as to improve the accuracy of the secondary air replenishment. At the same time, when the secondary air flows to the combustion chamber 10a through the inner insulation part 90, the inner insulation part 90 can also have a certain preheating effect on the secondary air.

[0099] Please refer to Figure 6 to Figure 7 In some embodiments, the outer edge of the outer heat insulation part 80 is provided with a first clamping edge 108, and the top 101 of the pot rack body 10 is provided with a first clamping groove 81, or the top 101 of the pot rack body 10 is provided with a first clamping edge 108, and the outer edge of the outer heat insulation part 80 is provided with a first clamping groove 81. The first clamping edge 108 can be arranged in an annular shape, and the first clamping groove 81 can also be arranged in an annular shape accordingly, wherein the first clamping edge 108 is engaged with the first clamping groove 81.

[0100] It can be understood that the first clamping edge 108 can be formed by stamping the outer edge of the outer heat insulating portion 80, and the first clamping groove 81 can be formed by stamping the top 101 of the pot support body 10, or the first clamping edge 108 can be formed by stamping the top 101 of the pot support body 10, and the first clamping groove 81 can be formed by stamping the outer edge of the outer heat insulating portion 80. In this way, manufacturing is convenient and the assembly steps can be reduced.

[0101] In this way, the outer heat insulating part 80 and the pot rack body 10 can be connected firmly by the cooperation between the first clamping edge 108 and the first clamping groove 81. In addition, during the actual disassembly and assembly process, the user can disassemble and assemble the outer heat insulating part 80 and the pot rack body 10 without using disassembly and assembly tools, which is very convenient.

[0102] Please refer to Figure 6 to Figure 7 In some embodiments, the inner edge of the inner heat insulation part 90 is provided with a second clamping edge 109, and the inner edge of the baffle ring 107 is provided with a second clamping groove 91, or the inner edge of the baffle ring 107 is provided with a second clamping edge 109, and the inner edge of the inner heat insulation part 90 is provided with a second clamping groove 91. The second clamping edge 109 can be arranged in an annular shape, and the second clamping groove 91 can also be arranged in an annular shape accordingly, wherein the second clamping edge 109 is engaged with the second clamping groove 91.

[0103] It can be understood that the second clamping edge 109 can be formed by stamping the inner edge of the inner heat insulating portion 90, and the second clamping groove 91 can be formed by stamping the inner edge of the baffle ring 107, or the second clamping edge 109 can be formed by stamping the inner edge of the baffle ring 107, and the second clamping groove 91 can be formed by stamping the inner edge of the inner heat insulating portion 90. In this way, manufacturing is convenient and the assembly steps can be reduced.

[0104] In this way, the inner heat insulating part 90 and the baffle ring 107 can be connected firmly by the cooperation between the second clamping edge 109 and the second clamping groove 91. In addition, during the actual disassembly and assembly process, the user can disassemble and assemble the inner heat insulating part 90 and the baffle ring 107 without using disassembly and assembly tools, which is very convenient.

[0105] See also Figure 4 In some embodiments, the outer heat insulation part 80 and the first heat exchange part 133 are integrally formed components. For example, the outer heat insulation part 80 and the first heat exchange part 133 can be directly manufactured by stamping, so that not only the connection between the two can be made more firmly, and the assembly steps can be reduced, but also the occurrence of gaps at the connection between the two can be reduced, so that the outer heat insulation part 80 and the first heat exchange part 133 have a higher degree of integration, so as to prevent heat from leaking from the connection between the two.

[0106] In other embodiments, the outer heat insulation part 80 can be a separate structure from the first heat exchange part 133 and connected by snap connection or threaded connection, etc., which is not limited in this embodiment.

[0107] See also Figure 4 In some embodiments, the inner heat insulating part 90 and the first heat exchanging part 133 are integrally formed components. For example, the inner heat insulating part 90 and the first heat exchanging part 133 can be directly manufactured by stamping, which not only makes the connection between the two more secure and reduces the assembly steps, but also reduces the occurrence of gaps at the connection between the two, so that the inner heat insulating part 90 and the first heat exchanging part 133 have a higher degree of integrity to prevent heat leakage from the connection between the two.

[0108] In other embodiments, the inner insulation part 90 can be a separate structure from the first heat exchange part 133 and connected by snap-fitting or threaded connection, etc., which is not limited in this embodiment.

[0109] See also Figure 4In some embodiments, the inner heat insulation part 90, the first heat exchange part 133 and the outer heat insulation part 80 are integrally formed components. For example, the inner heat insulation part 90, the first heat exchange part 133 and the outer heat insulation part 80 can be directly manufactured by stamping, so that not only the connection between the three parts can be made more firmly and the assembly steps can be reduced, but also the gap between the inner heat insulation part 90 and the first heat exchange part 133 and the gap between the outer heat insulation part 80 and the first heat exchange part 133 can be reduced, so that the inner heat insulation part 90, the first heat exchange part 133 and the outer heat insulation part 80 have a higher degree of integration to prevent heat leakage from the connection.

[0110] Please refer to Figures 5 and 6 In some embodiments, the projection of the heat exchange channel 13a on the pot rack body 10 is located within the bottom 102 of the pot rack body 10 when projected along the height direction of the pot rack 100. Based on this, the heat exchange channel 13a will not exceed the bottom 102 of the pot rack body 10, so that the integrity of the hole-digging heat exchanger 13 and the pot rack body 10 is stronger, and the wall surface of the heat exchange channel 13a can absorb the heat of the bottom 102 of the pot rack body 10 to transfer the heat to the secondary air.

[0111] Of course, the present application is not limited thereto. In other embodiments, when projected along the height direction of the pot rack 100 , part of the projection of the heat exchange channel 13a on the pot rack body 10 is located within the bottom 102 of the pot rack body 10 , and part of the projection is located on the inner side 103 .

[0112] See also Figure 6 In some embodiments, the pot support body 10 has an inner side surface 103 facing the combustion chamber 10a, and each heat exchange channel 13a extends from the outside to the inside toward the combustion chamber 10a.

[0113] The end 132 of each heat exchange channel 13a extending from the outside to the inside toward the combustion chamber 10a extends to the connection between the inner side surface 103 and the bottom 102 of the pot support body 10. Thus, compared with the form in which the heat exchange channel 13a does not extend to the connection between the inner side surface 103 and the bottom 102 of the pot support body 10, the extension length of the heat exchange channel 13a of this embodiment is longer, so that the heat exchange area between the wall surface of the heat exchange channel 13a and the secondary air can be increased to improve the heat exchange efficiency, thereby further improving the preheating effect of the secondary air.

[0114] Optionally, the end 132 of each heat exchange channel 13a extending from the outside to the inside toward the combustion chamber 10a can extend beyond the inner side surface 103 to partially extend into the combustion chamber 10a. In this way, compared with the form in which the heat exchange channel 13a does not extend to the connection between the inner side surface 103 and the bottom 102 of the pot rack body 10, the extension length of the heat exchange channel 13a of this embodiment is longer, so that the heat exchange area between the wall surface of the heat exchange channel 13a and the secondary air can be increased to improve the heat exchange efficiency, thereby further improving the preheating effect of the secondary air.

[0115] In other embodiments, the end 132 of each heat exchange channel 13a extending from the outside to the inside toward the combustion chamber 10a may not extend to the connection between the inner side surface 103 and the bottom 102 of the pot support body 10, and this embodiment does not limit this.

[0116] See also Figure 6 In some embodiments, the pot support body 10 further has an outer side surface 104 facing away from the combustion chamber 10a. Each heat exchange channel 13a extends from the outside to the inside toward the combustion chamber 10a, wherein the head end 131 of the heat exchange channel 13a extending from the outside to the inside toward the combustion chamber 10a does not exceed the outer side surface 104. For example, the head end 131 of the heat exchange channel 13a may extend to the connection between the outer side surface 104 and the bottom 102 of the pot support body 10, or the head end 131 of the heat exchange channel 13a may not extend to the connection between the outer side surface 104 and the bottom 102 of the pot support body 10.

[0117] In this way, during actual use, when the head end 131 of the heat exchange channel 13a does not exceed the outer surface 104, the probability of the user touching the head end 131 of the heat exchange channel 13a and getting scratched can be greatly reduced, thereby protecting the user's safety and improving the user's experience.

[0118] Of course, the present application is not limited thereto. In other embodiments, the head end 131 of the heat exchange channel 13a extending from the outside to the inside toward the combustion chamber 10a can exceed the outer side surface 104.

[0119] Please refer to Figures 5 and 6 In some embodiments, each heat exchange channel 13a extends radially of the pot support body 10. It can be understood that the fire outlet holes of the inner ring fire cover and the outer ring fire cover are arranged at intervals in the circumferential direction. On the basis that each heat exchange channel 13a extends radially, the secondary air flowing out of each heat exchange channel 13a can flow more accurately to the fire outlet hole corresponding to it in the radial direction, thereby improving the supplementary effect of the secondary air on the flame. In addition, the structure of the heat exchange channel 13a can be made simpler, so as to facilitate the manufacture of the hole-dug heat exchanger 13.

[0120] In some embodiments, each heat exchange channel 13a extends in a direction that forms an angle with the radial direction of the pot rack body 10. Thus, compared with the form in which each heat exchange channel 13a extends in the radial direction of the pot rack body 10, this embodiment can increase the length of the heat exchange channel 13a by forming an angle with the radial direction through the heat exchange channel 13a, thereby increasing the heat exchange area between the wall surface of the heat exchange channel 13a and the secondary air, and further improving the preheating effect of the secondary air.

[0121] See also Figure 8 In some embodiments, the cross-sectional area of ​​the heat exchange channel 13a is equal in the radial direction of the pot rack body 10. In this way, it is easy to design and manufacture the heat exchange channel 13a, and the impact of the secondary air on the wall of the heat exchange channel 13a due to the change of flow velocity and direction can be reduced.

[0122] In some embodiments, the heat exchange channel 13a is gradually expanded in the radial direction of the pot rack body 10 and in the direction toward the inside of the pot rack body 10. In this way, the secondary air can experience a change from narrow to wide during the flow in the heat exchange channel 13a, so as to increase the disturbance of the secondary air and make the secondary air in a turbulent state. The secondary air in the turbulent state can increase the effective heat exchange area between the heat exchange fins, thereby helping to improve the heat exchange efficiency between the secondary air and the surface of the heat exchange fins.

[0123] In some embodiments, the heat exchange channel 13a is arranged to be tapered in the radial direction of the pot rack body 10 and in the direction toward the inside of the pot rack body 10. In this way, the secondary air can experience a change from wide to narrow during the flow in the heat exchange channel 13a, increasing the turbulence of the secondary air, thereby increasing the contact area between the secondary air and the surface of the heat exchange fins, thereby helping to improve the heat exchange efficiency between the secondary air and the surface of the heat exchange fins.

[0124] In some embodiments, the diameter of the heat exchange channel 13a is greater than or equal to 8 mm and less than or equal to 14 mm. In this way, while ensuring that the heat exchange channel 13a and the secondary air have a certain heat exchange area, the overall height of the pot rack 100 can be prevented from being too high, and the distance between the bottom of the pot 2000 placed on the pot support 50 and the flame of the burner 200 is prevented from being too large to affect the heating effect of the burner 200 on the pot 2000.

[0125] When the diameter of the heat exchange channel 13a is less than 8 mm, the heat exchange area between the heat exchange channel 13a and the secondary air will be small, resulting in a low heat exchange efficiency between the heat exchange channel 13a and the secondary air, which in turn affects the combustion efficiency of the burner 200. When the diameter of the heat exchange channel 13a is greater than 14 mm, the height of the perforated heat exchanger 13 will be high, and the overall height of the pot rack 100 will be too high, which will cause the distance between the flame of the burner 200 and the bottom of the pot 2000 to be too large, reducing the heating effect of the burner 200 on the pot 2000.

[0126] For example, the diameter of the heat exchange channel 13a may be 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm or 14 mm, etc., which is not limited in this embodiment.

[0127] Of course, the present application is not limited thereto. In other embodiments, the diameter of the heat exchange channel 13a may also be greater than or equal to 1 mm and less than or equal to 19 mm.

[0128] In some embodiments, the height of the perforated heat exchanger 13 is greater than or equal to 10 mm and less than or equal to 30 mm. In this way, while ensuring that the heat exchange channel 13a of the perforated heat exchanger 13 has a certain heat exchange area with the secondary air, the overall height of the pot rack 100 can be prevented from being too high, and the distance between the bottom of the pot 2000 placed on the pot support 50 and the flame of the burner 200 is too large to affect the heating effect of the burner 200 on the pot 2000.

[0129] When the height of the perforated heat exchanger 13 is less than 10 mm, the heat exchange channel 13a of the perforated heat exchanger 13 does not have a certain heat exchange area with the secondary air, resulting in a low heat exchange efficiency between the heat exchange channel 13a and the secondary air, thereby affecting the combustion efficiency of the burner 200. When the height of the perforated heat exchanger 13 is greater than 30 mm, the overall height of the pot rack 100 is too high, which will cause the distance between the flame of the burner 200 and the bottom of the pot 2000 to be too large, reducing the heating effect of the burner 200 on the pot 2000.

[0130] For example, the height of the perforated heat exchanger 13 may be 10 mm, 15 mm, 20 mm, 25 mm or 30 mm, etc., which is not limited in this embodiment.

[0131] Of course, the present application is not limited thereto. In other embodiments, the height of the heat exchange channel 13a may be greater than or equal to 5 mm and less than or equal to 40 mm.

[0132] In some embodiments, the diameter of the heat exchange channel 13a is greater than or equal to 8 mm and less than or equal to 14 mm, and the height of the hole heat exchanger 13 is greater than or equal to 10 mm and less than or equal to 30 mm.

[0133] In this way, while ensuring that the heat exchange channel 13a has a certain heat exchange area with the secondary air and that the heat exchange channel 13a of the perforated heat exchanger 13 has a certain heat exchange area with the secondary air, it is possible to avoid the overall height of the pot rack 100 being too high, and to prevent the bottom of the pot 2000 placed on the pot support 50 from being too far away from the flame of the burner 200, thereby affecting the heating effect of the burner 200 on the pot 2000.

[0134] When the diameter of the heat exchange channel 13a is less than 8 mm, the heat exchange area between the heat exchange channel 13a and the secondary air will be small, resulting in a low heat exchange efficiency between the heat exchange channel 13a and the secondary air, which in turn affects the combustion efficiency of the burner 200. When the diameter of the heat exchange channel 13a is greater than 14 mm, the height of the perforated heat exchanger 13 will be high, which will make the overall height of the pot rack 100 too high, which will cause the distance between the flame of the burner 200 and the bottom of the pot 2000 to be too large, reducing the heating effect of the burner 200 on the pot 2000. When the height of the perforated heat exchanger 13 is less than 10 mm, the heat exchange channel 13a of the perforated heat exchanger 13 will not have a certain heat exchange area with the secondary air, resulting in a low heat exchange efficiency between the heat exchange channel 13a and the secondary air, which in turn affects the combustion efficiency of the burner 200. When the height of the perforated heat exchanger 13 is greater than 30 mm, the overall height of the pot rack 100 will be too high, which will cause the flame of the burner 200 to be too far away from the bottom of the pot 2000, reducing the heating effect of the burner 200 on the pot 2000.

[0135] Exemplarily, the diameter of the heat exchange channel 13a can be 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm or 14 mm, etc., and the height of the hole heat exchanger 13 can be 10 mm, 15 mm, 20 mm, 25 mm or 30 mm, etc., which is not limited in this embodiment.

[0136] Of course, the present application is not limited to this. In other embodiments, the diameter of the heat exchange channel 13a can also be greater than or equal to 1 mm and less than or equal to 19 mm. At the same time, the height of the heat exchange channel 13a can also be greater than or equal to 5 mm and less than or equal to 40 mm.

[0137] Please refer to Figures 4 to 5 In some embodiments, the perforated heat exchanger 13 is provided with a plurality of avoidance openings 13b. The pot rack 100 further includes support legs 60, which are used to be placed on the stove to support the pot rack body 10, so as to set the pot rack body 10 on the stove.

[0138] There are multiple supporting legs 60, which are arranged at intervals along the circumference of the pot rack 100 at the bottom 102 of the pot rack body 10, and one supporting leg 60 is correspondingly inserted into one avoidance opening 13b. In this way, the supporting effect of the pot rack body 10 can be improved by the multiple supporting legs 60 along the circumference of the pot rack 100.

[0139] Furthermore, along the height direction of the pot rack 100, the bottom of the support leg 60 is at the same height as the bottom of the perforated heat exchanger 13. On the basis of the pot rack body 10 being set up on the stove by the support of the support leg 60, the perforated heat exchanger 13 can also be in contact with the stove to partially support the pot rack body 10, so that the weight of the pot rack body 10 can be shared by the support leg 60 and the perforated heat exchanger 13, and the overall stability of the pot rack body 10 is improved, so as to avoid the occurrence of the situation such as the pot 2000 being tipped over due to unbalanced force.

[0140] Optionally, along the height direction of the pot rack 100, the bottom of the support leg 60 is lower than the bottom of the hole-punched heat exchanger 13. In this way, in this embodiment, only the support leg 60 plays a supporting role on the pot rack body 10, thereby preventing the hole-punched heat exchanger 13 from supporting the pot rack body 10 and causing deformation due to excessive force.

[0141] See also Figure 6 In some embodiments, the pot rack body 10 is a multi-layer structure and includes at least a top plate 105 and a bottom plate 106, and the bottom plate 106 is spliced ​​with the top plate 105 along the height direction of the pot rack 100. The hole heat exchanger 13 is arranged at the bottom of the bottom plate 106, that is, the first heat exchange part 133 is arranged at the bottom of the bottom plate 106. In addition, the outer heat insulation part 80 is connected to the top plate 105, and the baffle ring 107 is connected to the inner side of the top plate 105.

[0142] The bottom plate 106 and the top plate 105 cooperate to enclose a heat insulation chamber 10d. Thus, the heat insulation chamber 10d can reduce the heat in the combustion chamber 10a from being lost to the outside from the pot support body 10, so as to further improve the overall combustion efficiency of the burner 200.

[0143] Of course, the present application is not limited to this. In other embodiments, the pot rack body 10 may include, in addition to the top plate 105 and the bottom plate 106, a middle plate sandwiched between the top plate 105 and the bottom plate 106, or the pot rack body 10 may be a single-layer structure, which is not limited in this embodiment.

[0144] Please refer to Figures 9 and 10In some embodiments, the pot rack 100 further includes a pot support leg 50, which is used to support the bottom of the pot 2000. The pot support leg 50 may be in a long strip shape to increase the connection area between the pot support leg 50 and the bottom of the pot 2000, so as to improve the stability of the pot 2000 supported by the pot support leg 50, and the pot support leg 50 may be made of a material with high temperature resistance such as cast iron, which is not limited in this embodiment.

[0145] There are multiple pot legs 50, and the multiple pot legs 50 are connected to the top 101 of the pot rack body 10 along the circumference of the pot rack body 10. In this way, the supporting effect of the pot 2000 can be improved along the circumference of the pot rack body 10.

[0146] See also Fig. 9 Furthermore, the pot support leg 50 is inserted into the pot rack body 10 and connected to the support leg 60, and one pot support leg 50 and one support leg 60 are integrally formed components. In this way, it is only necessary to connect the pot support leg 50, which is an integrally formed component, with the support leg 60 and the pot rack body 10. Compared with the two steps of connecting the support leg 60 and the pot rack body 10, and connecting the pot support leg 50 and the pot rack body 10, this embodiment only requires one step, and the connection operation is more convenient. At the same time, on the basis that the pot support leg 50 and the support leg 60 are integrally formed components, the connection between the two is more secure.

[0147] See also Fig.10 Optionally, the pot support feet 50 and the support legs 60 can also be split structures. In this way, the pot support and the support legs 60 can be staggered or corresponded on the pot rack body 10 along the circumference of the pot rack 100, with more options.
