DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the following further describes this application in detail 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.

[0038] The present application provides a pot rack and a stove to solve the problem that when a burner is working, high-temperature flue gas is generated. The flue gas carries a lot of heat energy, but the heat exchange efficiency between the flue gas and the pot is low, resulting in the heat energy carried by the flue gas not being fully utilized.

[0039] In a first aspect, the present application provides a pot stand 100. As shown in FIG1 , the pot stand 100 includes a pot stand body 10 and pot legs 50. The pot stand body 10 is generally annular in shape. The pot legs 50 can be connected to the pot stand body 10 by a non-detachable method such as welding or integral molding. Alternatively, the pot legs 50 can be connected to the pot stand body 10 by a detachable method such as a snap-fit ​​or threaded connection. It is understood that the pot stand body 10 is an annular structure with a central through hole 105 provided at its center. The pot stand body 10 can be annular in shape, but of course, it can also be square in shape or other shapes depending on actual needs. The central through hole 105 can also be circular, square, or other shaped. The pot legs 50 are provided at the top 101 of the pot stand body 10. The pot legs 50 are configured to support pots and separate the pots from the pot stand body 10.

[0040] It should be noted that when the pot stand 100 is used, the burner 200 (as shown in FIG11 ) is placed at the central through hole 105 of the pot stand body 10. The pot stand body 10 is arranged around the burner 200. The pot is placed on the pot support leg 50 of the pot stand 100. The burner 200, the pot stand 100 and the pot form a combustion space. The pot support leg 50 separates the pot from the pot stand body 10, so that an air space is formed between the bottom surface of the pot and the top 101 of the pot stand body 10. The smoke generated by the burner 200 during combustion can be discharged. The high-temperature flame generated by the burner 200 passes through the central through hole 105 to heat the cookware by discharging the combustion space through the air passage space. The annular pot rack body 10 can separate the high-temperature flame generated by the burner 200 from the external environment, reducing the impact of the external low-temperature airflow on the flame and the loss of combustion heat. At the same time, it can allow the high-temperature flue gas to stay in the combustion space for a longer time, so that the high-temperature flue gas has enough time to fully exchange heat with the bottom surface of the cookware, thereby improving the heat exchange efficiency and the overall thermal efficiency of the burner 200.

[0041] As shown in FIG1 and FIG2 , in some embodiments of the present application, the pot stand 100 further includes a top baffle 42 , which is disposed on the top 101 of the pot stand body 10 and is connected to the pot legs 50 . The top baffle 42 can block the air passage space formed between the bottom surface of the pot and the top 101 of the pot stand body 10 , thereby preventing the smoke in the combustion space from flowing outward, allowing the smoke to stay in the combustion space for a longer time, and at the same time enhancing the disturbance of the smoke in the combustion space. Thereby, the heat exchange efficiency between the smoke and the cookware can be improved, and the heat energy carried by the smoke can be fully utilized. In addition, the top baffle 42 is connected to the pot support leg 50, and the pot support leg 50 is used to provide support for the top baffle 42. There is no need to connect the connecting piece to the top 101 of the pot rack body 10, so the installation and replacement of the top baffle 42 are more convenient. When the pot support leg 50 is detachable, when the pot rack 100 needs to be inspected and maintained, the top baffle 42 can also be disassembled and installed at the same time as the pot support leg 50.

[0042] In some embodiments, the top baffle 42 extends along the circumference of the pot rack body 10, so that the top baffle 42 can block more smoke from flowing outward, thereby allowing the smoke to stay in the combustion space for a longer time, thereby further improving the heat exchange efficiency between the smoke and the pot.

[0043] Among them, the top baffle 42 can extend continuously along the circumference of the pot support body 10, making the molding of the top baffle 42 simpler and more convenient; or, the top baffle 42 can extend discontinuously along the circumference of the pot support body 10, and the top baffle 42 includes multiple sections of baffle segments arranged at intervals along the circumference of the pot support body 10, so that the top baffle 42 can be set at multiple positions of the pot support body 10 on the basis of keeping the total length of the top baffle 42 unchanged.

[0044] Specifically, the top baffle 42 can extend along the circumference of the pot rack body 10, so that the top baffle 42 can block the smoke flowing outward in all directions, which can further improve the heat exchange efficiency between the smoke and the pot.

[0045] 1 and 2 , in some embodiments of the present application, a through hole 52 is provided on the pot support leg 50 for the top baffle 42 to pass through. The top baffle 42 extends along the circumference of the pot support body 10 to pass through the through hole 52, thereby realizing the connection between the top baffle 42 and the pot support leg 50, making the connection between the top baffle 42 and the pot support leg 50 simpler and more convenient, and the through hole 52 can be used to provide an effective limit for the top baffle 42 to prevent the top baffle 42 from separating from the pot support leg 50.

[0046] Furthermore, the shape of the through hole 52 is adapted to the shape of the cross section of the top spoiler 42 , and the size of the through hole 52 is adapted to the size of the cross section of the top spoiler 42 to reduce the gap between the top spoiler 42 and the inner wall of the through hole 52 to prevent the top spoiler 42 from shaking.

[0047] Continuing with Figures 1 and 2 , in some embodiments, a plurality of top baffles 42 are provided, and the plurality of top baffles 42 are arranged axially along the wok support body 10. It will be appreciated that the plurality of top baffles 42 are arranged vertically so that the top baffles 42 can block the air passage space as much as possible, thereby better preventing smoke in the combustion space from flowing outward. The number of top baffles 42 can be two, three, four, or more.

[0048] Among them, there is a gap between two adjacent top baffles 42, which can allow smoke to be discharged smoothly from the combustion space, so that the top baffle 42 can block the smoke in the combustion space from flowing outward, while preventing the top baffle 42 from completely blocking the air space and causing the smoke to be unable to be discharged.

[0049] In one embodiment, at least two top baffles 42 are staggered in the axial direction of the pot support body 10 , so that there is enough space between the top baffles 42 to set a gap without changing the size of the top baffles 42 .

[0050] Furthermore, two adjacent top baffles 42 are staggered in the axial direction of the pot rack body 10 so that there is enough space between any two adjacent top baffles 42 to set a gap; in addition, referring to Figure 2, the top baffle 42 arranged near the inner side can also block the gap between the top baffles 42 arranged near the outer side, so that the smoke needs to bypass the top baffle 42 arranged near the inner side before it can be discharged from the gap between the top baffles 42 arranged near the outer side, which can better block the smoke and enhance the circuitous flow of the smoke, thereby enhancing the disturbance of the smoke, and further improving the heat exchange efficiency between the smoke and the cookware.

[0051] In some embodiments, along the radial direction of the pot support body 10, the distance between the top baffle 42 and the outer edge of the pot support body 10 is smaller than the distance between the top baffle 42 and the inner edge of the pot support body 10. Taking the perspective of Figure 2 as an example, the top baffle 42 is arranged at a position closer to the outer edge of the pot support body 10, which can block the smoke in the combustion space from being discharged outward, and can also prevent the cold air outside the pot support body 10 from exchanging heat with the smoke in the combustion space, thereby reducing the heat loss of the smoke and further improving the heat exchange efficiency between the smoke and the cookware.

[0052] In some embodiments, the top spoiler 42 is an annular steel wire ring. It is understood that the top spoiler 42 is a ring-shaped structure formed by bending steel wire. Steel wire has advantages such as low cost, high structural strength, and heat resistance. This can reduce the production cost of the top spoiler 42 and allow the top spoiler 42 to be used for a longer period of time without frequent replacement. In addition, compared to copper wire, steel wire has relatively poor thermal conductivity and better thermal insulation performance.

[0053] As shown in Figures 3 to 5, in some embodiments of the present application, the top 101 of the pot stand body 10 includes a guide surface 1011. It is understood that when the pot is placed on the pot support legs 50, the pot support legs 50 separate the pot from the guide surface 1011, and an exhaust flow channel for smoke exhaust can be formed between the guide surface 1011 and the bottom surface of the pot. The guide surface 1011 can guide the smoke to be discharged outward.

[0054] The distance between the guide surface 1011 and the top surface of the pot leg 50 in the axial direction of the pot stand body 10 is d1, and 1 mm ≤ d1 ≤ 15 mm. It should be noted that the distance between the guide surface 1011 and the bottom surface of the pot is approximately equal to d1. When d1 is less than 1 mm, the distance between the outer edge of the guide surface 1011 and the pot is too small, resulting in an undersized exhaust duct, which may prevent smoke from being smoothly discharged from the combustion space. When d1 is greater than 15 mm, the distance between the outer edge of the guide surface 1011 and the pot is too large, resulting in an oversized exhaust duct. As a result, smoke in the combustion space will be quickly discharged from the exhaust duct outlet, reducing the heat exchange efficiency between the smoke and the pot and preventing the heat energy carried by the smoke from being fully utilized.

[0055] It should also be noted that in this embodiment, by designing d1, while ensuring that the smoke can be discharged smoothly through the exhaust flow channel, the distance between the guide surface 1011 and the bottom surface of the cookware is relatively small. This can narrow the exhaust flow channel, allowing the smoke to flow faster when discharged through the exhaust flow channel, thereby increasing the flow rate of the high-temperature smoke in the combustion space. This can increase the probability of the high-temperature smoke contacting the bottom surface of the cookware, resulting in a higher probability of the high-temperature smoke contacting and exchanging heat with the bottom surface of the cookware, thereby improving the heat exchange efficiency between the smoke and the cookware and fully utilizing the heat energy carried by the smoke. d1 can be 1 mm, 5 mm, 7 mm, 10 mm, 15 mm, or other values.

[0056] Furthermore, the top baffle 42 is positioned opposite to the guide surface 1011, and the top baffle 42 is arranged above the guide surface 1011, which can further narrow the exhaust flow channel formed by the guide surface 1011 and the bottom surface of the cookware, so that the flow rate of the flue gas when discharged through the exhaust flow channel is faster, thereby further increasing the flow rate of the high-temperature flue gas in the combustion space, and increasing the contact probability of the high-temperature flue gas with the bottom surface of the cookware, so that the high-temperature flue gas has a higher probability of contacting and exchanging heat with the bottom surface of the cookware, thereby improving the heat exchange efficiency between the flue gas and the cookware, and making full use of the heat energy carried by the flue gas.

[0057] In some embodiments of the present application, the distance between the outer edge of the guide surface 1011 and the top surface of the pot support leg 50 in the axial direction of the pot support body 10 is smaller than the distance between the inner edge of the guide surface 1011 and the top surface of the pot support leg 50 in the axial direction of the pot support body 10. Taking the perspective shown in Figure 4 as an example, the outer edge of the guide surface 1011 is higher than the inner edge of the guide surface 1011. It can be understood that the outer edge of the guide surface 1011 is the edge of the guide surface 1011 on the side away from the central through hole 105, and the inner edge of the guide surface 1011 is the edge of the guide surface 1011 on the side close to the central through hole 105. The air inlet of the exhaust flow channel is formed between the inner edge of the guide surface 1011 and the bottom surface of the cookware, and the air outlet of the exhaust flow channel is formed between the outer edge of the guide surface 1011 and the bottom surface of the cookware. The diameter of the air outlet of the exhaust flow channel is larger than the diameter of the air inlet of the exhaust flow channel, so that the flow rate of the flue gas when discharged through the exhaust flow channel is faster, which can further increase the flow rate of the high-temperature flue gas in the combustion space. In addition, there is a height difference between the outer edge of the guide surface 1011 and the inner edge of the guide surface 1011, so that the flue gas has a tendency to flow upward when flowing along the guide surface 1011, making it easier for the flue gas to contact the bottom surface of the cookware during discharge, thereby further improving the heat exchange efficiency between the flue gas and the cookware.

[0058] It should also be noted that although the flow rate of the flue gas is faster when it is discharged through the exhaust duct, since the diameter of the exhaust duct's air outlet is relatively small, the flow rate of the flue gas discharged through the exhaust duct's air outlet per unit time will be relatively low, thereby reducing the amount of flue gas discharged through the exhaust duct per unit time, so that more high-temperature flue gas stays in the combustion space per unit time, which can further improve the heat exchange efficiency between the flue gas and the cookware.

[0059] In some embodiments, the guide surface 1011 extends obliquely downward from the outer edge of the pot support body 10 to the inner edge of the pot support body 10. It can be understood that the outer edge of the pot support body 10 is the connection between the outer side surface 104 of the pot support body 10 and the top surface of the pot support body 10, and the inner edge of the pot support body 10 is the connection between the top surface of the pot support body 10 and the inner side surface 103 of the pot support body 10. In this embodiment, the outer edge of the guide surface 1011 coincides with the outer edge of the pot support body 10, and the guide surface 1011 extends obliquely from the outer edge of the pot support body 10 to the inner side of the pot support body 10 to the inner edge of the guide surface 1011. The guide surface 1011 can better guide the smoke from the guide surface 1011 to the inner edge of the pot support body 10. The inner edge of the flow surface 1011 flows upward to the outer edge of the guide surface 1011, which can increase the impact intensity of the smoke on the bottom surface of the cookware, thereby further improving the heat exchange efficiency between the smoke and the cookware. In addition, the inclined guide surface 1011 can play a certain blocking role on the smoke. The smoke flow easily swirls and forms a vortex when it impacts the guide surface 1011, which can increase the disturbance of the high-temperature smoke in the combustion space, so that the high-temperature smoke can stay in the combustion space for a longer time, which can further improve the heat exchange efficiency between the smoke and the cookware and reduce the heat energy loss of the smoke.

[0060] In one embodiment, as shown in FIG6 , the guide surface 1011 extends from the outer edge of the pot support body 10 to the inner edge of the pot support body 10; it is understandable that, in this embodiment, the inner edge of the guide surface 1011 coincides with the inner edge of the pot support body 10, which can extend the radial length of the guide surface 1011 along the pot support body 10, so that the guide surface 1011 has a sufficient length, thereby extending the length of the exhaust flow channel, so that the smoke can be discharged smoothly through the exhaust flow channel.

[0061] It should be noted that, in one embodiment, the flow guide surface 1011 may be an inclined surface; of course, in other embodiments, the flow guide surface 1011 may also be a flat surface, a curved surface, a wavy surface, a serrated surface, or other shapes. In one embodiment, the flow guide surface 1011 may completely coincide with the top surface of the pot support body 10, that is, the top surface of the pot support body 10 serves as the flow guide surface 1011; in other embodiments, the flow guide surface 1011 may be formed by only a portion of the top surface of the pot support body 10. In one embodiment, the flow guide surface 1011 may be a surface that continuously extends radially along the pot support body 10; in other embodiments, the flow guide surface 1011 may be formed by multiple segments of surfaces spaced apart radially along the pot support body 10.

[0062] Continuing with Figures 4 and 5 , in some embodiments, the angle formed between the guide surface 1011 and the top surface of the pot support leg 50 is α1, where 0 degrees ≤ α1 ≤ 45 degrees. It will be appreciated that when α1 is greater than 45 degrees, the angle of the guide surface 1011 relative to the top surface of the pot support leg 50 is too large, requiring the pot support body 10 to have sufficient thickness to accommodate the guide surface 1011. Furthermore, the pot support body 10 may be thinner at the inner edge of the guide surface 1011, affecting the structural strength of the pot support body 10. α1 can be 0 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 45 degrees, or other values.

[0063] In some embodiments, along the radial direction of the pot support body 10, the length of the pot support body 10 is R, and the length of the guide surface 1011 is r1, where 0.1R≤r1≤0.8R. It is understood that when r1 is less than 0.1R, the radial length of the guide surface 1011 along the pot support body 10 is too small, and the guide surface 1011's flue gas guidance effect is weak; when r1 is greater than 0.8R, the radial length of the guide surface 1011 along the pot support body 10 is too large, resulting in insufficient remaining area at the top 101 of the pot support body 10 for other structures. Here, r1 can be 0.1R, 0.3R, 0.5R, 0.8R, or other multiples of R. The specific value of R can be selected based on actual needs and is not limited in this application.

[0064] In some embodiments, the guide surface 1011 extends along the circumference of the pot support body 10, such that the guide surface 1011 is provided at multiple locations along the circumference of the pot support body 10. This allows smoke flowing in multiple directions to be guided through the guide surface 1011 before being discharged, thereby further increasing the probability of smoke contact with the bottom surface of the pot, thereby improving the heat exchange efficiency between the smoke and the pot, and fully utilizing the heat energy carried by the smoke. The guide surface 1011 can extend continuously along the circumference of the pot support body 10, making the formation of the guide surface 1011 simpler and more convenient. Alternatively, the guide surface 1011 can extend discontinuously along the circumference of the pot support body 10, comprising multiple sections of guide surface spaced apart along the circumference of the pot support body 10. This allows the guide surface 1011 to be provided at multiple locations on the pot support body 10 while maintaining the total length of the guide surface 1011.

[0065] Specifically, the guide surface 1011 extends along the circumference of the pot rack body 10, so that the smoke flowing in all directions can pass through the guide surface 1011 before being discharged, which can further improve the heat exchange efficiency between the smoke and the pot.

[0066] Continuing to refer to Figures 4 and 5, in some embodiments of the present application, the top 101 of the pot stand body 10 is provided with an energy-gathering sink 10c; the energy-gathering sink 10c is a groove-shaped structure formed on the top 101 of the pot stand body 10, and the notch 10c1 of the energy-gathering sink 10c faces upward. When the smoke is discharged from the combustion space, when the smoke flows to the energy-gathering sink 10c, the smoke first flows downward to the bottom of the energy-gathering sink 10c, and then climbs upward out of the energy-gathering sink 10c, so that the smoke flows more times in a circuitous manner, thereby making it easier for the smoke to form vortices during the flow, which can enhance the disturbance of the smoke in the combustion space, so that the smoke can stay in the combustion space for a longer time, thereby further improving the heat exchange efficiency between the smoke and the pot, and making full use of the heat energy carried by the smoke; in addition, the energy-gathering sink 10c can also be configured to accommodate liquid overflowing from the pot to prevent the liquid from flowing to the fire hole of the burner 200 and blocking the fire hole.

[0067] In some embodiments, the distance between the notch 10c1 of the energy-gathering sink 10c and the top surface of the pot support leg 50 in the axial direction of the pot support body 10 is greater than the distance between the outer edge of the pot support body 10 and the top surface of the pot support leg 50 in the axial direction of the pot support body 10. Taking the perspective shown in Figure 4 as an example, the notch 10c1 of the energy-gathering sink 10c is lower than the outer edge of the pot support body 10, so that after the smoke climbs up and out of the energy-gathering sink 10c in the energy-gathering sink 10c, the smoke needs to continue to flow upward to the outer edge of the pot support body 10, which can further enhance the disturbance of the smoke in the combustion space, thereby allowing the smoke to stay in the combustion space for a longer time; in addition, the smoke can be guided upward, so that the smoke has an upward flow tendency when discharged from the outer edge of the pot support body 10, so that the smoke is more likely to contact the bottom surface of the pot during the discharge process, thereby further improving the heat exchange efficiency between the smoke and the pot.

[0068] In some embodiments, the depth of the energy-gathering trough 10c is h, where 2 mm ≤ h ≤ 16 mm. It is understood that when the depth of the energy-gathering trough 10c is less than 2 mm, the depth of the energy-gathering trough 10c is too small, and the process of the flue gas flowing downward and climbing upward in the energy-gathering trough 10c is too short, resulting in a poor ability of the energy-gathering trough 10c to guide the flue gas into vortexes. When the depth of the energy-gathering trough 10c is greater than 16 mm, the depth of the energy-gathering trough 10c is too large, requiring the pot stand body 10 to be thicker, which increases the overall volume and cost of the pot stand 100. Here, h can be 2 mm, 5 mm, 10 mm, 15 mm, 16 mm, or other values.

[0069] In some embodiments, the width of the slot 10c1 of the energy-gathering trough 10c is greater than the width of the bottom of the energy-gathering trough 10c, so that the bottom of the energy-gathering trough 10c is relatively narrow, and the slot 10c1 of the energy-gathering trough 10c is relatively wide, so that after the flue gas flows to the bottom of the energy-gathering trough 10c, it can smoothly flow out of the energy-gathering trough 10c through the slot 10c1 of the energy-gathering trough 10c, thereby preventing a large amount of flue gas from accumulating at the bottom of the energy-gathering trough 10c and being unable to be discharged.

[0070] Furthermore, along the depth direction of the energy focusing trough 10c, the trough width of the energy focusing trough 10c gradually decreases, so that the trough wall of the energy focusing trough 10c is inclined, and the energy focusing trough 10c is roughly "V"-shaped. The trough wall of the energy focusing trough 10c has a good guiding effect, so that the flue gas flows downward along the trough wall of the energy focusing trough 10c to the trough bottom of the energy focusing trough 10c, and then climbs up out of the energy focusing trough 10c. The process is faster and smoother, which can further enhance the disturbance of the flue gas in the combustion space, so that the flue gas can stay in the combustion space for a longer time, thereby further improving the heat exchange efficiency between the flue gas and the cookware; in addition, the trough bottom of the energy focusing trough 10c can also be made narrower, which can prevent a large amount of flue gas from accumulating at the trough bottom of the energy focusing trough 10c and being unable to be discharged.

[0071] In some embodiments, the radial distance between the energy-gathering trough 10c and the inner edge of the pot support body 10 is less than the radial distance between the energy-gathering trough 10c and the outer edge of the pot support body 10. It is understood that when smoke is discharged from the inner side of the pot support body 10 to the outer side of the pot support body 10, the farther the smoke is from the inner edge of the pot support body 10, the greater the heat energy loss due to outward radiation of the smoke, and the lower the smoke temperature. In this embodiment, by placing the energy-gathering trough 10c closer to the inner edge of the pot support body 10, the higher-temperature smoke can pass through the energy-gathering trough 10c before being discharged. This allows the higher-temperature smoke to remain in the combustion space longer, reduces the heat energy loss due to outward radiation of the smoke, and further improves the heat exchange efficiency between the smoke and the cookware. The specific distance between the energy-gathering trough 10c and the inner edge of the pot support body 10 can be selected based on actual needs and is not detailed in this application.

[0072] In some embodiments, the energy-gathering trough 10 c is formed by a partially integral depression of the pot rack body 10 , so that the formation of the energy-gathering trough 10 c is more convenient and the overall structural strength of the pot rack body 10 can be increased.

[0073] In one embodiment, the energy-gathering trough 10c extends along the circumference of the pot support body 10, such that the energy-gathering trough 10c is provided at multiple locations along the circumference of the pot support body 10. This allows flue gas flowing in multiple directions to pass through the energy-gathering trough 10c before being discharged, thereby further enhancing the agitation of the flue gas within the combustion space, allowing the flue gas to remain within the combustion space for a longer period of time, and further improving the heat exchange efficiency between the flue gas and the cookware. The energy-gathering trough 10c can extend continuously along the circumference of the pot support body 10, making the formation of the energy-gathering trough 10c more simple and convenient. Alternatively, the energy-gathering trough 10c can extend intermittently along the circumference of the pot support body 10, comprising multiple segments spaced apart along the circumference of the pot support body 10. This allows the energy-gathering trough 10c to be provided at multiple locations along the pot support body 10 while maintaining its total length.

[0074] Specifically, the energy-gathering sink 10c extends along the circumference of the pot rack body 10, so that the smoke flowing in all directions can pass through the energy-gathering sink 10c before being discharged, which can further improve the heat exchange efficiency between the smoke and the pot.

[0075] 4 and 5 , in one embodiment, the guide surface 1011 and the energy-gathering trough 10c are arranged in sequence toward the inner side of the pot support body 10, and the distance between the outer edge of the guide surface 1011 and the top surface of the pot support leg 50 in the axial direction of the pot support body 10 is smaller than the distance between the notch 10c1 of the energy-gathering trough 10c and the top surface of the pot support leg 50 in the axial direction of the pot support body 10. Taking the perspective shown in FIG4 as an example, the outer edge of the guide surface 1011 is higher than the notch 10c1 of the energy-gathering trough 10c, so that the smoke flowing out of the energy-gathering trough 10c upward can continue to flow upward along the guide surface 1011, which can further increase the impact strength of the smoke on the bottom surface of the cookware, thereby further improving the heat exchange efficiency between the smoke and the cookware.

[0076] In one embodiment, the guide surface 1011 extends obliquely downward from the outer edge of the pot rack body 10 to connect with the groove wall of the energy-gathering trough 10c, so that the smoke flowing out of the energy-gathering trough 10c can continue to flow upward directly along the guide surface 1011, so that the smoke can flow upward more smoothly, further increasing the impact strength of the smoke on the bottom surface of the cookware.

[0077] It should also be noted that when the top 101 of the pot rack body 10 is provided with an energy-gathering trough 10c, and the guide surface 1011 extends from the outer edge of the pot rack body 10 to the inner edge of the pot rack body 10, the guide surface 1011 can be staggered with the energy-gathering trough 10c in the circumferential direction of the pot rack body 10, and the guide surface 1011 can extend from the gap between two adjacent trough splits to the inner edge of the pot rack body 10.

[0078] Continuing to refer to Figures 4 and 5, in some embodiments of the present application, the pot stand 100 further includes a fire protrusion ring 41, which is arranged at the top 101 of the pot stand main body 10. The distance between the convex top of the fire protrusion ring 41 and the top surface of the pot support leg 50 in the axial direction of the pot stand main body 10 is smaller than the distance between the inner edge of the pot stand main body 10 and the top surface of the pot support leg 50 in the axial direction of the pot stand main body 10. Taking the perspective shown in Figure 4 as an example, the convex top of the fire protrusion ring 41 is higher than the inner edge of the pot stand main body 10, so that the fire protrusion ring 41 can block the outward flowing smoke and increase the residence time of the smoke in the combustion space. In addition, the fire protrusion ring 41 can prevent the heat of the smoke from radiating outward, thereby improving the heat exchange efficiency between the smoke and the cookware, and making full use of the heat energy carried by the smoke.

[0079] In some embodiments, the distance between the top of the fire protrusion 41 and the top surface of the pot support 50 in the axial direction of the pot support body 10 is d2, and 5 mm ≤ d2 ≤ 15 mm. It is understood that when d2 is less than 5 mm, the distance between the top of the fire protrusion 41 and the pot is too small, and the fire protrusion 41 may affect the smooth discharge of smoke from the combustion space; when d2 is greater than 15 mm, the distance between the top of the fire protrusion 41 and the pot is too large, resulting in the fire protrusion 41 not being able to effectively block the smoke, thereby reducing the heat exchange efficiency between the smoke and the pot.

[0080] It should also be noted that in this embodiment, by designing d2, while ensuring that smoke can be discharged smoothly, the convex top of the near-fire convex ring 41 has a sufficient height, thereby effectively blocking the outward-flowing smoke. This allows the smoke to remain in the combustion space for a sufficient period of time, thereby improving the heat exchange efficiency between the smoke and the cookware and fully utilizing the heat energy carried by the smoke. d2 can be 5 mm, 7 mm, 10 mm, 15 mm, or other values.

[0081] In some embodiments, the fire protrusion ring 41 includes a first side surface 411 located near the inner edge of the pot support body 10. The first side surface 411 extends obliquely downward from the convex top of the fire protrusion ring 41 to the inner edge of the pot support body 10. This allows the first side surface 411 to better guide the smoke from the inner edge of the pot support body 10 upward to the convex top of the fire protrusion ring 41. This allows the smoke to flow upward along the first side surface 411, thereby increasing the impact strength of the smoke on the bottom surface of the pot and further improving the heat exchange efficiency between the smoke and the pot. It should be noted that in one embodiment, the first side surface 411 may be an inclined surface; of course, in other embodiments, the first side surface 411 may also be a flat surface, a curved surface, a wavy surface, a serrated surface, or other shapes.

[0082] In some embodiments, the angle formed between the first side surface 411 and the top surface of the pot support leg 50 is α2, with a range of 10 degrees ≤ α2 ≤ 25 degrees. It is understood that when α2 is less than 10 degrees, the inclination of the first side surface 411 relative to the top surface of the pot support leg 50 is too small, the upward flue gas guidance effect of the first side surface 411 is weak, and it is difficult to achieve a large height difference between the convex top of the fire protrusion ring 41 and the inner edge of the pot support body 10 without changing the radial length of the convex top of the fire protrusion ring 41 and the inner edge of the pot support body 10. This results in a poor smoke blocking effect of the fire protrusion ring 41. When α2 is greater than 25 degrees, the inclination of the first side surface 411 relative to the top surface of the pot support leg 50 is too large, requiring the pot support body 10 to have sufficient thickness to accommodate the first side surface 411, which increases the volume and cost of the pot support body 10. α2 can be 10 degrees, 15 degrees, 20 degrees, 25 degrees, or other values.

[0083] In some embodiments, the length of the first side surface 411 along the radial direction of the pot support body 10 is r2, where 0.1R≤r2≤0.8R. It is understood that when r2 is less than 0.1R, the radial length of the first side surface 411 along the pot support body 10 is too small, and the first side surface 411 has a weaker effect on guiding smoke. When r2 is greater than 0.8R, the radial length of the first side surface 411 along the pot support body 10 is too large, resulting in insufficient remaining area on the top 101 of the pot support body 10 for other structures. Here, r2 can be 0.1R, 0.3R, 0.5R, 0.8R, or other multiples of R.

[0084] In some embodiments, along the radial direction of the pot support body 10, the distance between the fire protrusion ring 41 and the outer edge of the pot support body 10 is greater than the distance between the fire protrusion ring 41 and the inner edge of the pot support body 10. This allows the fire protrusion ring 41 to be positioned closer to the inner edge of the pot support body 10. This allows the fire protrusion ring 41 to prevent the higher-temperature flue gas at the inner edge of the pot support body 10 from being discharged outward, allowing the higher-temperature flue gas to remain in the combustion space for a longer period of time and reducing the heat energy loss of the flue gas radiating outward, thereby further improving the heat exchange efficiency between the flue gas and the cookware. The specific distance value between the fire protrusion ring 41 and the inner edge of the pot support body 10 can be selected according to actual needs and is not detailed in this application.

[0085] In some embodiments, only one near-fire convex ring 41 may be provided, which can reduce the number of near-fire convex rings 41 and reduce the production process difficulty and production cost of the pot rack 100; in other embodiments, multiple near-fire convex rings 41 may also be provided, and multiple near-fire convex rings 41 are arranged at intervals along the radial direction of the pot rack body 10, and multiple near-fire convex rings 41 can successively block the outward-flowing smoke, so that the smoke can stay in the combustion space for a longer time, wherein two, three or more near-fire convex rings 41 can be provided.

[0086] In some embodiments, the fire near protrusion ring 41 is integrally formed with the pot rack body 10. The fire near protrusion ring 41 can be formed by a portion of the pot rack body 10 that protrudes upward, which can enhance the connection strength between the fire near protrusion ring 41 and the pot rack body 10 and prevent the fire near protrusion ring 41 from separating from the pot rack body 10.

[0087] In one embodiment, the flame protrusion 41 extends along the circumference of the pot support body 10, such that the flame protrusion 41 is provided at multiple locations along the circumference of the pot support body 10. This allows smoke flowing in multiple directions to pass through the flame protrusion 41 before being discharged, thereby blocking more smoke and allowing the smoke to remain in the combustion space for a longer period of time, thereby further improving the heat exchange efficiency between the smoke and the cookware. The flame protrusion 41 can extend continuously along the circumference of the pot support body 10, making the formation of the flame protrusion 41 simpler and more convenient. Alternatively, the flame protrusion 41 can extend intermittently along the circumference of the pot support body 10, comprising multiple segments spaced apart along the circumference of the pot support body 10. This allows the flame protrusion 41 to be provided at multiple locations on the pot support body 10 while maintaining its total length.

[0088] Specifically, the fire-near convex ring 41 extends along the circumference of the pot rack body 10, so that the fire-near convex ring 41 can block the smoke flowing outward in all directions, which can further improve the heat exchange efficiency between the smoke and the pot.

[0089] Continuing to refer to Figures 4 and 5, in some embodiments of the present application, the guide surface 1011 and the fire-prone convex ring 41 are arranged in sequence toward the inner side of the pot rack body 10, so that the guide surface 1011 can be combined with the fire-prone convex ring 41 to play a double blocking role on the smoke flowing outward.

[0090] Furthermore, the distance between the convex top of the fire near convex ring 41 and the top surface of the pot support leg 50 in the axial direction of the pot support body 10 is smaller than the distance between the inner edge of the guide surface 1011 and the top surface of the pot support leg 50 in the axial direction of the pot support body 10, and is larger than the distance between the outer edge of the guide surface 1011 and the top surface of the pot support leg 50 in the axial direction of the pot support body 10. Taking the perspective shown in Figure 4 as an example, the convex top of the fire near convex ring 41 is higher than the inner edge of the guide surface 1011 and lower than the outer edge of the guide surface 1011, so that when the smoke passing over the fire near convex ring 41 flows toward the guide surface 1011, it can first flow downward along the fire near convex ring 41 and then move upward along the guide surface 1011 to a higher position, so that the smoke can make more circuitous flows during the flow process, thereby making it easier for the smoke to form vortices during the flow process, which can enhance the disturbance of the smoke in the combustion space, so that the smoke can stay in the combustion space for a longer time, thereby further improving the heat exchange efficiency between the smoke and the cookware.

[0091] In some embodiments of the present application, the guide surface 1011, the energy-gathering trough 10c and the near-fire convex ring 41 are arranged in sequence toward the inner side of the pot rack body 10, so that the guide surface 1011, the energy-gathering trough 10c and the near-fire convex ring 41 can be combined and sequentially configured as smoke flowing outward, thereby further improving the heat exchange efficiency between the smoke and the cookware.

[0092] In one embodiment, the near-fire convex ring 41 includes a second side surface 412 close to the energy-gathering trough 10c. The second side surface 412 can extend from the convex top of the near-fire convex ring 41 to connect with the groove wall surface of the energy-gathering trough 10c, so that the smoke passing over the near-fire convex ring 41 can flow directly downward into the energy-gathering trough 10c, so that the smoke can flow downward more smoothly.

[0093] In another embodiment, the second side surface 412 can extend from the convex top of the near-fire convex ring 41 to the outer edge of the guide surface 1011, or the second side surface 412 can extend from the convex top of the near-fire convex ring 41 to the outer edge of the pot support body 10; it should be noted that when the top 101 of the pot support body 10 is provided with the guide surface 1011 and the energy-gathering sink 10c, and the second side surface 412 extends from the convex top of the near-fire convex ring 41 to the outer edge of the guide surface 1011, the near-fire convex ring 41 can be staggered with the energy-gathering sink 10c in the circumferential direction of the pot support body 10, and the second side surface 412 can be separated from the two adjacent sinks. The gap between them extends to the inner edge of the pot support body 10; when the top 101 of the pot support body 10 is provided with a guide surface 1011 and an energy-gathering trough 10c, and the second side surface 412 extends from the convex top of the near-fire convex ring 41 to the outer edge of the pot support body 10, the near-fire convex ring 41 can be staggered with the energy-gathering trough 10c in the circumferential direction of the pot support body 10, and the near-fire convex ring 41 can be staggered with the guide surface 1011 in the circumferential direction of the pot support body 10, and the second side surface 412 can extend from the gap between two adjacent trough splits and the gap between two adjacent guide surfaces to the inner edge of the pot support body 10.

[0094] 3 and 7 , in one embodiment of the present application, the pot support leg 50 is connected to the guide surface 1011, so that the length of the pot support leg 50 along the axial direction of the pot stand body 10 is the distance between the guide surface 1011 and the top surface of the pot support leg 50 in the axial direction of the pot stand body 10. By designing the length of the pot support leg 50 along the axial direction of the pot stand body 10, the distance between the guide surface 1011 and the top surface of the pot support leg 50 in the axial direction of the pot stand body 10 can be a preset distance, thereby making the manufacture of the pot stand 100 more convenient.

[0095] It should also be noted that there are multiple pot legs 50, and the multiple pot legs 50 can be arranged at intervals along the circumference of the pot rack body 10. The number of pot legs 50 can be two, three, four or more, and the shape of the pot legs 50 can also be various, for example, V-shaped, I-shaped or other irregular shapes.

[0096] Continuing with Figures 3 and 7 , in one embodiment of the present application, the pot legs 50 extend radially along the pot support body 10, and the projection of the pot legs 50 on the pot support body 10 partially overlaps the energy-concentrating trough 10c. It will be appreciated that the pot legs 50 are partially located above the energy-concentrating trough 10c, thereby partially shielding the trough 10c from the pot legs 50. As smoke flows upward along the trough walls of the energy-concentrating trough 10c in the portion shielded by the pot legs 50, it is blocked by the pot legs 50, causing the smoke to flow toward the sides of the pot legs 50 and inward of the pot support body 10. This enhances smoke agitation within the combustion space, thereby allowing the smoke to remain within the combustion space for a longer period of time.

[0097] Furthermore, the pot support leg 50 crosses the energy focusing trough 10c from above, so that the part of the energy focusing trough 10c opposite to the position of the pot support leg 50 can be completely blocked by the pot support leg 50, so that more flue gas flowing into the energy focusing trough 10c can be blocked by the pot support leg 50, which can further enhance the disturbance of the flue gas in the combustion space, so that the flue gas can stay in the combustion space for a longer time.

[0098] In one embodiment of the present application, the pot support leg 50 has a drainage surface 51 facing the energy-gathering trough 10c, and the drainage surface 51 is arranged to face away from the top surface of the pot support leg 50. The drainage surface 51 extends upwardly and obliquely toward the inner side of the pot rack body 10, so that the smoke blocked by the pot support leg 50 in the energy-gathering trough 10c can flow back along the drainage surface 51 toward the inner side of the pot rack body 10 and flow upward, so that the smoke can stay in the combustion space for a longer time and has a greater chance of contacting the bottom surface of the pot.

[0099] As shown in Figures 8 and 9, in some embodiments of the present application, the pot stand 100 further includes a top spoiler 43 disposed at the top 101 of the pot stand body 10. The top spoiler 43 has an exhaust passage 433 extending through the inner and outer sides of the top spoiler 43. It is understood that when a fluid encounters an obstacle during its flow, several rotating vortices are formed behind the obstacle (the formation principle of a crescent-shaped sand dune). Furthermore, when a fluid passes through a narrow passage such as a pipe or channel, the changes in flow velocity and friction can also form rotating vortices. In this embodiment, by providing the top spoiler 43 with the exhaust passage 433, when smoke from the combustion space is discharged, the smoke encounters the top spoiler 43 and forms vortices there. Furthermore, the smoke discharged through the exhaust passage 433 can also form vortices, thereby enhancing the agitation of the smoke, thereby extending the residence time of the smoke within the combustion space, improving the heat exchange efficiency between the smoke and the pot, and fully utilizing the heat energy carried by the smoke.

[0100] The top spoiler 43 can be integrally formed with the pot rack body 10 , and the top spoiler 43 can also be connected to the pot rack body 10 by welding, clamping, threaded connection, riveting or other methods.

[0101] In some embodiments, a plurality of top spoilers 43 are provided, and the plurality of top spoilers 43 are arranged at intervals along the circumference of the pot rack body 10, so that the smoke flowing outward in multiple directions can be disturbed by the top spoilers 43, thereby allowing more smoke to stay in the combustion space for a longer time, thereby further improving the heat exchange efficiency between the smoke and the pot.

[0102] Furthermore, the multiple top spoilers 43 can be evenly arranged along the circumference of the pot support body 10, so that the top spoilers 43 more evenly disturb the smoke. Furthermore, the multiple top spoilers 43 can be evenly arranged along the circumference of the pot support body 10, so that the smoke flowing outward in all directions can be disturbed by the top spoilers 43, which can further improve the heat exchange efficiency between the smoke and the pot.

[0103] In some embodiments, the spacing between two adjacent top spoilers 43 is greater than the circumferential width of the exhaust passage 433 along the pot support body 10. It is understood that when exhausting, the smoke may also be discharged from the gap between two adjacent top spoilers 43. Compared to the gap between two adjacent top spoilers 43, the exhaust passage 433 is relatively narrow, so that the pressure of the smoke flowing through the gap between two adjacent top spoilers 43 is lower than the pressure of the smoke flowing through the exhaust passage 433. This creates a pressure difference between the inside and outside of the exhaust passage 433. Driven by this pressure difference, the smoke is more likely to form vortices, which can enhance smoke turbulence, thereby extending the residence time of the smoke in the combustion space, improving the heat exchange efficiency between the smoke and the pot, and fully utilizing the heat energy carried by the smoke.

[0104] In some embodiments, the exhaust passage 433 has a first opening 434 facing the inside of the pot support body 10 and a second opening 435 facing the outside of the pot support body 10. The width of the second opening 435 along the circumference of the pot support body 10 is greater than the width of the first opening 434 along the circumference of the pot support body 10. It will be understood that the first opening 434 serves as the air inlet of the exhaust passage 433, and the second opening 435 serves as the air outlet of the exhaust passage 433. The first opening 434 is narrower than the second opening 435, resulting in a pressure difference between the first opening 434 and the second opening 435. Driven by the pressure difference, the smoke in the exhaust passage 433 is more likely to form vortices, thereby enhancing smoke turbulence and improving the heat exchange efficiency between the smoke and the cookware.

[0105] Furthermore, the width of the exhaust channel 433 along the circumference of the pot rack body 10 gradually decreases toward the inner edge of the pot rack body 10, so that the air pressure in the exhaust channel 433 gradually increases toward the inner edge of the pot rack body 10, so that there can be a large air pressure difference between the first opening 434 and the second opening 435, making it easier for the smoke in the exhaust channel 433 to form a vortex; in addition, the inner wall of the exhaust channel 433 extends obliquely toward the inner edge of the pot rack body 10, so that the inner wall of the exhaust channel 433 can play a better guiding role.

[0106] Continuing to refer to Figures 8 and 9, the exhaust channel 433 passes through the top spoiler 43 in a direction away from the pot rack body 10. Taking the perspective shown in Figure 8 as an example, the top 101 of the exhaust channel 433 is an opening, so that the smoke in the exhaust channel 433 can also flow upward to form a vortex, thereby further enhancing the disturbance of the smoke.

[0107] In some embodiments, the top spoiler 43 includes a first top spoiler 431 and a second top spoiler 432 disposed on the top 101 of the pot support body 10. The second top spoiler 432 and the first top spoiler 431 are spaced apart along the circumference of the pot support body 10, and an exhaust passage 433 is defined between the second top spoiler 432 and the first top spoiler 431. It will be understood that the first top spoiler 431 and the second top spoiler 432 can be the same or different. Compared to forming the exhaust passage 433 through a perforation process in the top spoiler 43, in this embodiment, the exhaust passage 433 of a specific shape can be formed by designing the position of the second top spoiler 432 and the first top spoiler 431, thereby saving the cost of the perforation process.

[0108] The first top spoiler 431 and the second top spoiler 432 are both planar and extend radially along the pot rack body 10. This can reduce the flow resistance of the smoke when it is discharged through the exhaust channel 433, so that the smoke can be discharged smoothly.

[0109] In some embodiments, the distance between the top surface of the pot support leg 50 and the top 101 of the pot support body 10 in the axial direction of the pot support body 10 is greater than the distance between the top surface of the top spoiler 43 and the top 101 of the pot support body 10 in the axial direction of the pot support body 10. It will be understood that, taking the perspective shown in FIG. 8 as an example, the top surface of the pot support leg 50 is higher than the top surface of the top spoiler 43, which can prevent the top spoiler 43 from being higher than the pot support leg 50 and affecting the stable placement of the pot on the pot support leg 50.

[0110] In some embodiments, the top spoiler 43 can be set on the guide surface 1011, and the distance between the guide surface 1011 and the bottom surface of the cookware is relatively short, so that the distance between the top surface of the top spoiler 43 and the bottom surface of the cookware can be relatively short. When the smoke in the exhaust channel 433 flows upward through the opening of the top 101 of the exhaust channel 433, the smoke is more likely to contact the bottom surface of the cookware, thereby improving the heat exchange efficiency between the smoke and the cookware.

[0111] In some embodiments, as shown in Figures 3 and 4, the pot rack 100 further includes a plurality of support legs 60, which are disposed at the bottom 102 of the pot rack body 10 and are configured to support the pot rack body 10; the plurality of support legs 60 can be arranged at intervals along the circumference of the pot rack body 10 to provide more stable support for the pot rack body 10.

[0112] It should be noted that the pot rack 100 may be a single-layer heat-insulating structure, as shown in FIG. 4 and FIG. 10 . In some embodiments, the pot rack 100 may also be a multi-layer heat-insulating structure.

[0113] Specifically, the pot rack body 10 includes an upper plate 106 and a lower plate 107. The upper plate 106 includes a top 101; the lower plate 107 is located below the upper plate 106, and the lower plate 107 is connected to the upper plate 106, and is enclosed with the upper plate to form an insulating cavity 10d. The insulating cavity 10d can play a role in insulation. The insulating cavity 10d can prevent the heat in the combustion space from dissipating outward, thereby reducing the heat energy loss of the burner 200, and can further improve the overall thermal efficiency of the burner 200.

[0114] Furthermore, the heat-insulating cavity 10d is a closed and sealed cavity, which can further enhance the heat-insulating function of the heat-insulating cavity 10d, thereby further reducing the heat energy loss of the burner 200.

[0115] In a second aspect, the present application further provides a stove 1000 , as shown in FIG11 . The stove 1000 includes a burner 200 and a pot rack 100 as in any one of the above embodiments. The central through hole 105 of the pot rack 100 is configured to accommodate the burner 200 .

[0116] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0117] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
