[0039] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0040] Please also refer to Figures 1 to 3 , an embodiment of the present application provides a pot rack 100 and a stove 1000 , the stove 1000 includes the pot rack 100 and a burner 200 .

[0041] The burner 200 includes an inner combustion section 210 and an outer combustion section 220 surrounding the inner combustion section 210. An air passage 230 is formed between the inner and outer combustion sections 210 and 220. A gas passage is formed within the burner 200, and both the outer and inner combustion sections 220 and 210 are provided with flame holes 240 that communicate with the gas passage. Specifically, a mixture of gas and primary air is ejected from the flame holes 240 of the burner 200 and ignited by an ignition device. This mixture, aided by the secondary air, forms a flame that can be used to heat the cookware.

[0042] In some structural forms, the burner 200 may include a gas distribution plate, an inner ring fire cover 250, and an outer ring fire cover 260. The gas distribution plate and the inner ring fire cover 250 are connected to form the inner combustion section 210, and the gas distribution plate and the outer ring fire cover 260 are connected to form the outer combustion section 220. The gas distribution plate can be an integrated structure or a split structure, which is not limited in this application.

[0043] The pot support 100 is used in conjunction with the burner 200 . The pot support 100 is arranged in a ring shape and is arranged around the outer periphery of the burner 200 .

[0044] An insulating cavity 110 and an air supply channel 120 are formed inside the pot rack 100. A combustion cavity 130 is provided on the inner side of the pot rack 100. The insulating cavity 110 surrounds the outer peripheral side of the combustion cavity 130. The combustion cavity 130 is used to be arranged above the burner 200 to accommodate the flue gas generated during the combustion process of the burner 200. It can be understood that a central through hole is formed through the lower cavity wall of the combustion cavity 130. The flame generated by the burner 200 heats the cookware through the central through hole and the combustion cavity 130. The flue gas generated by the burner 200 is discharged from the combustion cavity 130 through the gap between the cookware and the top of the pot rack 100.

[0045] The air supply channel 120 is connected to the combustion chamber 130 and has an air outlet 131 on the wall of the combustion chamber 130. The air outlet 131 is located above the outer combustion portion 220. Secondary air enters the combustion chamber 130 through the air supply channel 120 and the air outlet 131, thereby replenishing the secondary air for the burner 200. This helps to improve the combustion efficiency of the stove 1000, save energy, reduce environmental pollution, and also improve the cooking effect and user experience. The number of air outlets 131 can be multiple, and multiple air outlets 131 are arranged at intervals along the circumference of the pot rack 100. The air outlet 131 can also be a single air outlet 131 and arranged in an annular shape. No specific limitation is made here.

[0046] The combustion chamber 130 has an inclined portion 142 formed on its wall. This portion is located above the air outlet 131 and extends from the inside outward from the bottom up. It should be noted that the inclined portion 142 need not be annular. In this case, there may be multiple inclined portions 142, spaced apart around the circumference of the pot support 100. The inclined portion 142 may also be annular, and this is not specifically limited here.

[0047] The pot rack 100 can be in a square ring shape, a circular ring shape, or other shapes, which are not specifically limited here. The pot rack 100 can be made of cast iron, enameled or galvanized materials with advantages such as high temperature resistance, good strength and good thermal conductivity.

[0048] The air supply channel 120 can be arranged in a ring shape or in a strip shape, which is not specifically limited here. When the air supply channel 120 is in a strip shape, the cross-section of the air supply channel 120 can be various, including a circular cross-section, a square cross-section, or other cross-sections, which are not specifically limited here. The air supply channel 120 extends at least radially along the pot rack 100, and can extend in a wavy shape or in a straight line, which is not specifically limited here.

[0049] In this embodiment of the present application, when cooktop 1000 is in use, the flue gas generated by burner 200 contacts the walls of combustion chamber 130, exchanging heat and heating the walls. The provision of inclined portion 142 increases the contact area between the walls of combustion chamber 130 and the flue gas, allowing the walls of combustion chamber 130 to absorb more heat, raising the temperature of the walls. Consequently, the secondary air receives more heat as it passes through air outlet 131, thereby enhancing the preheating effect of the secondary air by the pot support 100 and improving the combustion efficiency of cooktop 1000. Furthermore, inclined portion 142 better guides the flue gas from its inner edge to its outer edge, increasing the impact strength of the flue gas on the bottom surface of the pot, thereby improving the heat exchange efficiency between the flue gas and the pot. Furthermore, the provision of inclined portion 142 prevents the flame generated by burner 200 from burning the walls of combustion chamber 130, thereby preventing the flame from burning the pot support 100. The provision of the heat-insulating cavity 110 can reduce the loss of heat from the flue gas in the combustion cavity 130 , thereby improving the combustion efficiency of the stove 1000 .

[0050] Specifically, see Figure 4The pot rack 100 includes an upper cover 140 and a lower cover 150 arranged in a ring shape; the upper cover 140 has a main body 141, an inclined portion 142, an air outlet 143 and an air inlet 144 connected in sequence, one end of the inclined portion 142 is connected to the end of the main body 141 close to the burner 200, and the other end of the inclined portion 142 extends downward from the direction close to the burner 200, the air outlet 143 is connected to the end of the inclined portion 142 away from the main body 141, and is provided with an air outlet 131, and the air inlet 144 is connected to the main body 141. The air outlet portion 143 is connected to one end away from the inclined portion 142 and extends in a direction away from the burner 200; one end of the lower cover 150 is sealedly connected to one end of the main body 141 away from the inclined portion 142, and the other end of the lower cover 150 extends between the main body 141 and the air inlet portion 144, and is surrounded by the air inlet portion 144 to form an air supply channel 120; wherein, the main body 141, the inclined portion 142 and the air outlet portion 143 are surrounded to form a combustion chamber 130, and the lower cover 150 and the main body 141 are surrounded to form an insulation chamber 110.

[0051] It is understood that the main body 141, the inclined portion 142, the air outlet 143, the air inlet 144, and the air supply channel 120 are all arranged in an annular shape. Secondary air enters the combustion chamber 130 through the air supply channel 120, the space between the air inlet 144 and the inclined portion 142, and the air outlet 131 in sequence.

[0052] This arrangement improves the efficiency of secondary air entering the air supply channel 120. Furthermore, the adjacent arrangement of the inclined portion 142 and the air outlet portion 143 allows the air supply channel 120 to communicate with the inclined portion 142. This allows both the inclined portion 142 and the air outlet portion 143 to exchange heat with the secondary air, thereby enhancing the pot rack 100's preheating effect on the secondary air and improving the combustion efficiency of the cooktop 1000. Furthermore, by positioning the inclined portion 142 on the inner edge of the pot rack 100, the flame generated by the burner 200 can be effectively prevented from burning the inner edge of the pot rack 100.

[0053] It should be noted that the inclined portion 142 and the air outlet portion 143 can exchange heat with the secondary air by heat radiation, or by contact, which is not specifically limited here.

[0054] Further, see Figure 3 The lower cover 150, located at one end near the burner 200, is spaced from or in contact with the inclined portion 142 in the radial direction of the pot support 100. This arrangement prevents the lower cover 150 from blocking the inclined portion 142 in the axial direction of the pot support 100, thereby allowing the inclined portion 142 to better exchange heat with the secondary air entering between the inclined portion 142 and the air inlet 144. This improves the pot support 100's preheating effect on the secondary air and enhances the combustion efficiency of the cooktop 1000.

[0055] Considering that secondary air may enter the insulation cavity 110 through the gap between the lower cover 150 and the main body 141, thereby affecting the insulation effect of the insulation cavity 110, a shielding portion 151 is provided on the end of the lower cover 150 near the burner 200, which projects upward. The shielding portion 151 is located on the surface of the lower cover 150 facing away from the air inlet portion 144. This arrangement reduces the gap between the lower cover 150 and the main body 141 through the shielding portion 151, thereby reducing the entry of secondary air into the insulation cavity 110 and further reducing the impact of secondary air on the insulation cavity 110.

[0056] The shielding portion 151 can be arranged in a ring shape, or the shielding portion 151 can be formed by multiple protrusions, and the multiple protrusions are arranged at intervals along the circumference of the pot rack 100. Preferably, the shielding portion 151 is arranged in a ring shape, so that secondary air can be better blocked from entering the insulation cavity 110.

[0057] See also Figure 4 In some embodiments of the present application, the pot support 100 further includes a middle cover 160. The middle cover 160 is annular and located within the heat-insulating cavity 110, thereby dividing the heat-insulating cavity 110 into an upper heat-insulating cavity 111 and a lower heat-insulating cavity 112. This arrangement improves the insulation effect of the heat-insulating cavity 110 by providing the middle plate, thereby reducing heat loss within the combustion cavity 130 and improving the thermal efficiency of the cooker 1000.

[0058] It should be noted that the middle cover 160 can be connected to the upper cover 140 or the lower cover 150, without any specific limitation herein. The middle cover 160 can be a steel plate, a stainless steel plate, or other materials, without any specific limitation herein.

[0059] Further, please also refer to Figure 2 as well as Figure 4 The outer edge of the middle cover 160 is provided with a protruding welding portion 161. The welding portion 161 extends away from the inner edge of the pot stand 100 and is connected to the lower surface of the main body 141. This arrangement, through the connection and fixation of the welding portion 161 to the lower surface of the main body 141, prevents the middle cover 160 from affecting the connection between the lower cover 150 and the upper cover 140. At the same time, the protruding welding portion 161 provides more operating space for welding the middle cover 160 and the upper cover 140, thereby facilitating the assembly of the pot stand 100.

[0060] In some embodiments of the present application, the main body 141 extends obliquely downward from the outer edge of the pot stand 100 toward the inner edge of the pot stand 100. With this arrangement, the main body 141 can better guide the flue gas to flow upward from the inner edge of the main body 141 to the outer edge of the main body 141, thereby increasing the impact strength of the flue gas on the bottom of the pot, thereby further improving the heat exchange efficiency between the flue gas and the pot. The inclined main body 141 can provide a certain barrier to the flue gas, and the flue gas flow easily swirls and forms a vortex when it impacts the main body 141. This can increase the disturbance of the high-temperature flue gas in the combustion chamber 130, thereby allowing the high-temperature flue gas to stay in the combustion chamber 130 for a longer time, further improving the heat exchange efficiency between the flue gas and the pot, and reducing the heat energy loss of the flue gas.

[0061] See also Figure 4 In some embodiments of the present application, a fire protrusion ring 141a is provided on the upper surface of the main body 141. The distance between the convex top of the fire protrusion ring 141a and the air inlet portion 144 in the axial direction of the pot support 100 is greater than the maximum distance between the inclined portion 142 and the air inlet portion 144 in the axial direction of the pot support 100. With this arrangement, the convex top of the fire protrusion ring 141a is higher than the outer edge of the inclined portion 142, allowing the fire protrusion ring 141a to block outward-flowing smoke, thereby increasing the residence time of the smoke in the combustion chamber 130. Furthermore, the fire protrusion ring 141a prevents heat from the smoke from radiating outward, thereby improving the heat exchange efficiency between the smoke and the cookware.

[0062] Further, see Figure 3 The protruding ring 141a near the fire has a first side surface 141b near the inclined portion 142. The first side surface 141b extends obliquely downward from the convex top of the protruding ring 141a near the fire to the inclined portion 142. This configuration allows the first side surface 141b to better guide the smoke from the inner edge of the pot rack 100 upward to the convex top of the protruding ring 141a near the fire, so that the smoke has an upward flow tendency when flowing along the first side surface 141b, which can increase the impact strength of the smoke on the bottom surface of the pot, thereby further improving the heat exchange efficiency between the smoke and the pot. It should be noted that in one embodiment, the first side surface 141b can be an inclined surface; of course, in other embodiments, the first side surface 141b can also be a flat surface, a curved surface, a wavy surface, a serrated surface, or other shapes.

[0063] See also Figure 1In some embodiments of the present application, an energy-gathering sink 141c is provided on the upper surface of the main body 141. The energy-gathering sink 141c is arranged in a ring shape. The energy-gathering sink 141c and the fire-prone convex ring 141a are arranged in sequence toward the inner side of the pot rack 100. With such arrangement, when the smoke is discharged from the combustion chamber 130, when the smoke passes over the near-fire convex ring 141a and flows to the energy-gathering trough 141c, the smoke first flows downward to the bottom of the energy-gathering trough 141c, and then climbs upward out of the energy-gathering trough 141c, so that the smoke makes more circuitous flows during the flow process, and thus makes it easier for the smoke to form vortices during the flow process, which can enhance the disturbance of the smoke in the combustion chamber 130, so that the smoke can stay in the combustion chamber 130 for a longer time, thereby further improving the heat exchange efficiency between the smoke and the cookware, and thus making full use of the heat energy carried by the smoke; in addition, the energy-gathering trough 141c can also be used to accommodate liquid overflowing from the cookware to prevent the liquid from flowing to the fire hole 240 of the burner 200 and blocking the fire hole 240.

[0064] See also Figure 4 In some embodiments of the present application, the width of the opening of the energy-gathering trough 141c is greater than the width of the bottom of the energy-gathering trough 141c. This configuration results in a relatively narrow bottom of the energy-gathering trough 141c and a relatively wide opening of the energy-gathering trough 141c. This allows smoke to flow smoothly through the opening of the energy-gathering trough 141c after reaching the bottom of the energy-gathering trough 141c, thus preventing a large amount of smoke from accumulating at the bottom of the energy-gathering trough 141c and being unable to be discharged.

[0065] Further, see Figure 4 The width of the energy-gathering trough 141c gradually decreases along its depth. This configuration results in the inclined walls of the energy-gathering trough 141c, which forms a roughly V-shaped shape. The walls of the energy-gathering trough 141c provide excellent flow guidance, allowing the flue gas to flow down along the walls to the bottom of the trough 141c before ascending and exiting the trough 141c more quickly and smoothly. This further enhances the flue gas's turbulence within the combustion chamber 130, allowing the flue gas to remain within the combustion chamber 130 for a longer period of time, thereby further improving the heat exchange efficiency between the flue gas and the cookware.

[0066] See also Figure 2In some embodiments of the present application, the pot stand 100 further includes a pot support leg 170, which comprises a supporting portion 171 and a connecting portion 172, interconnected with each other. The supporting portion 171 is located above the energy-concentrating trough 141c and is used to support the pot. One end of the connecting portion 172 is connected to the supporting portion 171, while the other end of the connecting portion 172 extends into the energy-concentrating trough 141c and connects to the wall or bottom of the trough 141c. This arrangement allows the energy-concentrating trough 141c to limit the radial position of the connecting portion 172 in the pot stand 100, thereby fully utilizing the space within the energy-concentrating trough 141c and simplifying the structure of the pot stand 100.

[0067] The pot support 100 can be affected by the pot and shake. If the pot support 100 contacts the burner 200, it will affect the burner 200 and thus the flame released by the burner 200. In view of this, the air inlet 144 is located above the burner 200, and the lower surface of the air inlet 144 is vertically spaced from the burner 200. This arrangement prevents the pot support 100 from affecting the burner 200 during cooking, thus ensuring stability during cooking.
