Description

Technical Field

[0001] This application relates to the field of kitchen and bathroom appliances technology, and in particular to a high-efficiency pot support and a gas stove. Background Technology

[0002] The energy-concentrating pot support is a key component in gas stoves used to improve thermal efficiency and optimize heat utilization. Currently, most energy-concentrating pot supports are single- or double-layered ring structures, primarily made of cast iron with a high-temperature resistant coating. By surrounding the flame and the bottom of the pot, the energy-concentrating pot support reflects and concentrates the heat generated by combustion onto the bottom area, reducing radiative heat loss to the surrounding environment and improving the efficiency of heat transfer to the bottom of the pot.

[0003] In related technologies, the heat in the internal insulation cavity of the double-layer energy-concentrating boiler support is lost through radiation and is not utilized, resulting in a large amount of preheating being wasted and the thermal efficiency of the gas being low. Utility Model Content

[0004] This application discloses a gas pot support and a gas stove that can improve the thermal efficiency of gas.

[0005] To achieve the above objectives, the first aspect of this application discloses a power-concentrating pot support, comprising:

[0006] The energy-concentrating ring is hollow and the hollow part of the energy-concentrating ring is configured to be located at the bottom of the corresponding cookware. A heat insulation cavity is formed inside the energy-concentrating ring. The energy-concentrating ring has a first side and a second side that are axially upward.

[0007] Multiple support legs, each connected to the energy-concentrating ring, are spaced apart circumferentially along the energy-concentrating ring. At least partially protruding from the first side of the energy-concentrating ring, each support leg supports the cookware.

[0008] Multiple flow guides are provided, which extend from the first side of the energy-concentrating ring to the second side, such that the flow guides are at least partially located in the heat insulation cavity, and the flow guides are located between two adjacent legs in the circumferential direction of the energy-concentrating ring.

[0009] The flow guide has:

[0010] Guide cavity;

[0011] An air inlet is provided, which faces the second side of the energy-concentrating ring and is connected to the flow guide cavity. The air inlet is used to supply air into the flow guide cavity.

[0012] An air outlet is connected to the flow guide cavity, and the air outlet is located above the air inlet along the axial direction of the energy-concentrating ring.

[0013] The energy-concentrating pot support of this application forms a heat-insulating cavity inside the energy-concentrating ring. When the gas is ignited, a large amount of heat is generated and transferred to the energy-concentrating ring. The energy-concentrating ring then exchanges heat with the air inside the heat-insulating cavity, achieving heat transfer to the air within the heat-insulating cavity. Simultaneously, because the energy-concentrating pot support of this application has a guide member extending from a first side to a second side on the energy-concentrating ring, and the guide member is at least partially located within the heat-insulating cavity, with an air inlet for air to enter the guide cavity and an air outlet located above the inlet, the air entering the guide cavity can exchange heat with the air inside the heat-insulating cavity. This preheats the external air before it is delivered to the combustion zone of the gas. In other words, the energy-concentrating pot support of this application, with the guide member located inside the heat-insulating cavity, allows the preheated air to recover and utilize the heat that would otherwise be lost through radiation from the wall of the energy-concentrating ring. This recovered heat is then transferred to the bottom of the pot or the gas combustion zone, reducing gas heat loss and thus improving gas thermal efficiency.

[0014] As an optional implementation, the energy-concentrating ring includes:

[0015] Inner wall;

[0016] The outer wall and the inner wall are arranged opposite each other along the radial direction of the energy-concentrating ring. The inner wall is closer to the hollow part relative to the outer wall along the radial direction of the energy-concentrating ring. The air outlet faces the inner wall.

[0017] By orienting the air outlet towards the inner wall (i.e., towards the hollow part near the bottom of the cookware), the external air delivered by the guide can be precisely directed to the core combustion area. This directional airflow not only replenishes oxygen for combustion but also creates an inward airflow thrust, helping the gas flame to converge towards the bottom of the cookware, reducing the loss of gas flame diffusion, and further enhancing the heat concentration effect of the energy-concentrating ring.

[0018] As an optional implementation, the flow guide includes:

[0019] First top plate section;

[0020] A first guide plate portion, one end of which is connected to the first top plate portion, and the other end of which extends to the second side of the energy-concentrating ring body. The first guide plate portion and the first top plate portion are connected at one end, and the air outlet is provided at the end where the first guide plate portion and the first top plate portion are connected. Along the radial direction of the energy-concentrating ring body, the first guide plate portion is disposed close to the inner wall so that the air outlet faces the inner wall.

[0021] The second guide plate portion is arranged facing the first guide plate portion along the radial direction of the energy-concentrating ring body. One end of the second guide plate portion is connected to the first top plate portion, and the other end of the second guide plate portion extends to the second side of the energy-concentrating ring body. The air inlet is formed between the other end of the second guide plate portion and the other end of the first guide plate portion. Along the radial direction of the energy-concentrating ring body, the second guide plate portion is arranged close to the outer wall.

[0022] The first top plate portion, the first guide plate portion, and the second guide plate portion together define the guide cavity.

[0023] The first and second guide plates extend from the first top plate to the second side (bottom) of the energy-concentrating ring, thus forming a complete airflow channel that runs through the heat insulation cavity. The air inlet is constructed from the gap between the ends of the two guide plates, which allows for precise design of the opening area and angle of the air inlet, thereby better adapting to the energy-concentrating pot support.

[0024] As an optional implementation method,

[0025] The flow guide also includes:

[0026] A flanged portion is connected to one end of the first guide plate portion and the second guide plate portion near the second side. The portion of the flanged portion connected to the first guide plate portion and the portion of the flanged portion connected to the second guide plate portion together define the air inlet.

[0027] The outer wall includes:

[0028] Outer ring bottom wall;

[0029] The outer ring sidewall is connected to the outer ring bottom wall, and a first clearance opening is provided on the side of the outer ring sidewall near the outer ring bottom wall. The first clearance opening is connected to the heat insulation cavity. The flow guide is inserted through the first clearance opening so that the flange is located outside the first clearance opening. The flange is connected to the outer ring sidewall and the outer ring bottom wall so that the flow guide is connected to the energy-concentrating ring body.

[0030] The flanged portion is connected to the portion of the first and second guide plates near the second side (i.e., the side facing the cooktop), and is also connected to the outer ring sidewall and the outer ring bottom wall, respectively. In this way, along the axial direction of the energy-concentrating ring, the connection between the flanged portion and the outer ring bottom wall restricts the upward or downward axial movement of the guide component. Simultaneously, along the radial direction of the energy-concentrating ring, the connection between the flanged portion and the outer ring sidewall prevents the guide component from radially shifting towards the center (hollow part) or the outer side of the energy-concentrating ring, thereby ensuring the stability of the guide component during use.

[0031] As an optional implementation, the second guide plate is provided with a slot, and the slot and the flange together form a hook. The side of the outer ring sidewall near the bottom wall of the outer ring engages with the hook so that the flange is connected to the outer ring sidewall.

[0032] The flanged portion has an abutting surface, which abuts against the bottom wall of the outer ring to connect the flanged portion and the bottom wall of the outer ring.

[0033] The hook portion is constructed by the slot and flange of the second guide plate, and engages with the side of the outer ring sidewall near the bottom wall of the outer ring. Thus, along the radial direction of the energy-concentrating ring, the inner side of the hook portion (the side near the hollow section) can lock onto the edge of the outer ring sidewall, preventing the guide component from shifting towards the center (hollow section) of the energy-concentrating ring, thereby avoiding deviation of the outlet due to radial displacement. Simultaneously, along the axial direction of the energy-concentrating ring, the hook portion, in conjunction with the flange, abuts against the bottom wall of the outer ring, providing axial fixation to the outer ring sidewall and preventing the guide component from moving axially along the energy-concentrating ring, thus ensuring the stability of the guide component.

[0034] In addition, the flanged part abuts against the bottom wall of the outer ring through the contact surface, and engages with the side wall of the outer ring through the hook part. This allows the energy-concentrating ring or the flow guide to be quickly disassembled and replaced when it is necessary to replace them, thus eliminating the need for a complete replacement and reducing the component replacement cost of the energy-concentrating pot support.

[0035] As an optional implementation, the two ends of the flow guiding cavity are the air inlet and the air outlet, respectively. Along the direction from the first side to the second side, the first flow guiding plate is inclined towards the side closer to the outer wall, and the second flow guiding plate is also inclined towards the side closer to the outer wall. The inclination angle of the second flow guiding plate in the axial direction of the energy-concentrating ring is greater than the inclination angle of the first flow guiding plate in the axial direction of the energy-concentrating ring, so that the flow guiding cavity is widened at the air inlet.

[0036] Along the direction from the first side (i.e., the side where the cookware is located) to the second side (i.e., the side of the cooktop), both the first and second baffle plates are inclined towards the side closer to the outer wall, with the second baffle plate having a larger inclination angle, thus widening the air inlet. This widened air inlet can capture air from a wider area, allowing more air to be delivered to the baffle chamber and then to the combustion zone, thereby preventing interruption of combustion or decreased combustion efficiency due to insufficient air supply.

[0037] As an optional implementation, the energy-concentrating boiler support further includes a heat insulation layer, wherein at least one of the first guide plate portion and the second guide plate portion has the heat insulation layer on a surface opposite to the guide cavity; and / or,

[0038] At least one of the first guide plate portion and the second guide plate portion has a surface facing away from the guide cavity that is constructed as a non-flat surface.

[0039] Since the flow channel is used to transport secondary air, when the energy-concentrating ring accumulates heat, the high temperature inside the insulation cavity will heat the air inside the flow channel through the first and second flow channels. However, overheating may cause the air to expand, which would reduce the oxygen content per unit volume. Therefore, by setting up an insulation layer, we can both prevent the air inside the flow channel from being underheated, thus avoiding a decrease in the oxygen concentration.

[0040] By constructing at least one of the first and second guide vanes, the surface of the part facing away from the guide cavity is made into a non-flat surface. This increases the contact area between the first and second guide vanes and the air in the insulation cavity, thereby improving the heat exchange effect between the air in the guide cavity and the air in the insulation cavity, and ensuring that the secondary air transported by the guide cavity can be fully heated.

[0041] As an optional implementation, the energy-concentrating ring includes:

[0042] Inner ring body;

[0043] The second top plate portion is connected to the inner ring body;

[0044] An outer ring body is connected to the inner ring body on one side along the axial direction of the energy-concentrating ring body, and the outer ring body is connected to the second top plate portion on the other side along the axial direction of the energy-concentrating ring body, so that the outer ring body, the inner ring body and the second top plate portion together form the heat insulation cavity;

[0045] The inner ring body and the second top plate are connected on one side with a second clearance opening. The second clearance opening is connected to the heat insulation cavity and is configured to allow the flow guide to pass through.

[0046] The second clearance opening is located at the connection between the inner ring and the second top plate, near the bottom of the pot. This allows the air guide to be inserted through the second clearance opening, with its outlet also close to the bottom of the pot, thus delivering outside air to the bottom and ensuring more complete combustion of the gas. Simultaneously, because the outer ring, inner ring, and second top plate together form a heat insulation cavity, the second clearance opening ensures that the integrity of the heat insulation cavity is not compromised. This allows the entire energy-concentrating ring support to simultaneously achieve both secondary air replenishment and heat insulation.

[0047] As an optional implementation, the flow guide is detachably connected to the energy-concentrating ring; and / or,

[0048] The area of ​​the air inlet is larger than the area of ​​the air outlet; and / or,

[0049] The energy-concentrating pot support also includes a filter element, which is disposed at the air inlet to filter the air passing through the air inlet.

[0050] After long-term use, oil stains (such as cooking fumes and soup splatter) can easily accumulate inside the airflow chamber of the stove. The detachable connection design between the airflow guide and the energy-concentrating ring allows users or maintenance personnel to easily remove the airflow guide and thoroughly clean the oil stains on the inner wall of the airflow chamber by rinsing or wiping. This prevents the airflow from being blocked by oil stains, which could lead to a reduction in air intake or a misalignment of the air outlet, and ensures that the airflow guide maintains its optimal working condition for a long time.

[0051] According to the fluid continuity equation (flow rate = cross-sectional area × velocity), when the air flow rate is stable, the smaller the cross-sectional area, the greater the velocity. With the inlet area larger than the outlet area, the external air entering the guide cavity from the inlet will have a higher velocity due to the reduced cross-sectional area, thus quickly delivering the external air to the combustion zone. This prevents air from stagnating in the guide cavity and ensures timely oxygen replenishment in the combustion zone.

[0052] Furthermore, in a kitchen environment, the air may contain dust, oil fume particles, and cooking residue (such as flour and vegetable scraps). If these directly enter the airflow chamber, they can easily adhere to the inner wall of the airflow deflector, clogging the chamber over time. Therefore, this application incorporates a filter at the air inlet to filter the air passing through it, preventing external impurities from entering the airflow chamber and causing blockage that could affect the airflow deflector's effectiveness.

[0053] The second aspect of this application discloses a gas stove, including the energy-concentrating pot support described in any of the first aspects above.

[0054] In this way, during the use of the gas stove, the heat loss of the gas at the burner can be reduced by the energy-concentrating pot support. At the same time, the guide of the energy-concentrating pot support can be used to transport the outside air to the combustion zone, thereby improving the combustion efficiency of the gas. Furthermore, the outside air is preheated in the guide cavity, which can recover the heat of the gas and transport it to the gas combustion zone or the bottom of the pot, thereby improving the thermal efficiency of the gas stove.

[0055] Compared with the prior art, the beneficial effects of this application are:

[0056] The energy-concentrating pot support and gas stove provided in this application utilize multiple guide elements spaced apart along the circumference of the energy-concentrating ring. These guide elements extend from a first side of the energy-concentrating ring to a second side, ensuring that at least a portion of the guide elements are located within the heat insulation cavity. The air inlet of each guide element allows air to enter the heat insulation cavity, and the air outlet communicates with the heat insulation cavity, positioned above the air inlet along the axial direction of the energy-concentrating ring. Because the guide elements are at least partially located within the heat insulation cavity, which accumulates a large amount of heat during gas ignition, the air entering the heat insulation cavity can exchange heat with the guide elements, thus preheating the air before it enters the combustion zone. This preheated air can recover and utilize the heat that would otherwise be lost through radiation from the heat insulation cavity wall, transferring the recovered heat to the bottom of the pot or the combustion zone, thereby reducing heat loss and improving the thermal efficiency of the gas.

Detailed Implementation

[0072] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0073] In this application, the terms "upper," "left," "right," "front," "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0074] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0075] Furthermore, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0076] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0077] In the use of gas stoves, combustion efficiency and thermal efficiency are two core indicators for measuring their performance. Combustion efficiency hinges on whether the gas is fully burned. Incomplete combustion not only wastes energy but also produces toxic gases such as carbon monoxide (CO), posing safety hazards. Thermal efficiency refers to the percentage of total heat generated by gas combustion that is actually utilized by the user; essentially, it measures the "effectiveness of heat utilization."

[0078] The energy-concentrating pot support is a key component in gas stoves used to improve thermal efficiency and optimize heat utilization. Currently, most energy-concentrating pot supports are single- or double-layered ring structures, primarily made of cast iron with a high-temperature resistant coating. By surrounding the flame and the bottom of the pot, the energy-concentrating pot support reflects and concentrates the heat generated by combustion onto the bottom area, reducing radiative heat loss to the surrounding environment and improving the efficiency of heat transfer to the bottom of the pot.

[0079] In related technologies, the energy-concentrating cooker support uses a flow guiding structure on the outside of the support to allow external air to exchange heat with the outer wall of the energy-concentrating cooker support within the flow guiding structure. However, the heat of the energy-concentrating cooker support is mainly concentrated inside the support, and the temperature of the outer wall is relatively low. As a result, less heat can be transferred to the secondary air, and the effect on improving the thermal efficiency of the gas is not significant.

[0080] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0081] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of the energy-concentrating pot support provided in an embodiment of this application.

[0082] In some embodiments, the energy-concentrating pot support 100 includes an energy-concentrating ring 1, which is hollow. The hollow portion 11 of the energy-concentrating ring 1 is configured to correspond to the bottom of the pot. In use, the energy-concentrating ring 1 is generally arranged around the outer periphery of the burner head 202, that is, the burner head 202 is located inside the hollow portion 11 of the energy-concentrating ring 1. Most of the heat generated by the flame emitted by the burner head 202 is confined within the hollow portion 11 of the energy-concentrating ring 1 to reduce heat loss. The pot is then placed above the energy-concentrating ring 1, so that the hollow portion 11 of the energy-concentrating ring 1 roughly corresponds to the bottom of the pot, allowing the flame emitted by the burner head 202 to be concentrated at the bottom of the pot.

[0083] Please combine Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of the energy-concentrating ring provided in the embodiments of this application. Figure 3 for Figure 2 A cross-sectional view at point AA. In some embodiments, a heat-insulating cavity 12 is formed inside the energy-concentrating ring 1. That is, the energy-concentrating ring 1 is constructed with a hollow annular heat-insulating cavity 12, which can typically be filled with air. In this way, the heat insulation effect of the energy-concentrating ring 1 can be improved by utilizing the air in the heat-insulating cavity 12, further reducing heat loss. At the same time, by setting the energy-concentrating ring 1 as a hollow structure, the weight of the energy-concentrating ring 1 can be reduced, thereby reducing the manufacturing cost of the energy-concentrating ring 1.

[0084] Please see Figure 1 , Figure 4 and Figure 5 , Figure 4 This is a top view of the energy-concentrating pot support provided in the embodiment of this application. Figure 5 This is a side view of the energy-concentrating pot support provided in an embodiment of this application. In some embodiments, the energy-concentrating ring 1 has a first side 13 and a second side 14 along the axial direction. The energy-concentrating pot support 100 includes a plurality of legs 2, all of which are connected to the energy-concentrating ring 1. The plurality of legs 2 are spaced apart circumferentially along the energy-concentrating ring 1. The plurality of legs 2 at least partially protrude from the first side 13 of the energy-concentrating ring 1 to support the pot.

[0085] It is understandable that the first side 13 is the side where the top of the energy-concentrating ring 1 is located, that is, the side closer to the cookware, and the second side 14 is the side where the bottom of the energy-concentrating ring 1 is located, that is, the side farther away from the cookware.

[0086] Understandably, multiple legs 2 protrude from the same side of the energy-concentrating ring 1 and support the cookware on that side.

[0087] Optionally, there are at least three support legs 2. The three support legs 2 can provide at least three support points for the cookware. The three support points support the cookware in a coplanar manner, which can improve the support effect and keep the position of the cookware stable.

[0088] It is understood that the support leg 2 and the energy-concentrating ring 1 can be integrally molded or manufactured separately and then connected together. This embodiment does not specifically limit this.

[0089] Please refer to the figure. In some embodiments, the energy-concentrating ring support also includes a plurality of flow guides 3, which are inserted along the first side 13 of the energy-concentrating ring body 1 to the second side 14, so that the flow guides 3 are at least partially located in the heat insulation cavity 12, and the flow guides 3 are located between two adjacent legs 2 along the circumferential direction of the energy-concentrating ring body 1.

[0090] It is understandable that, taking the example of setting three support legs 2, the three support legs 2 should be evenly spaced along the circumference of the energy-concentrating ring 1. At this time, there should also be three flow guides 3, which are located between two adjacent support legs 2. This allows the flow guides 3 to completely avoid the connection area of ​​the support legs 2, ensuring the structural integrity of the support legs 2 and maximizing the use of the non-support area of ​​the energy-concentrating ring 1 by the flow guides 3, thus avoiding mutual interference between the support legs and the flow guides.

[0091] It is understood that the material of the above-mentioned guide component 3 can be stainless steel, aluminum alloy or ceramic, etc., and this embodiment does not make specific limitations on this.

[0092] Optionally, please refer to Figure 1 , Figures 5 to 7 ,in, Figure 6 for Figure 4 Sectional view at point BB. Figure 7 for Figure 6 A partial enlarged view at point C. In some embodiments, the flow guide 3 has a flow guide cavity 31, an air inlet 32, and an air outlet 33. The air inlet 32 ​​faces the second side 14 of the energy-concentrating ring 1 and communicates with the flow guide cavity 31, allowing air to enter the flow guide cavity 31. The air outlet 33 communicates with the flow guide cavity 31 and is located above the air inlet 32 ​​along the axial direction of the energy-concentrating ring 1.

[0093] The energy-concentrating cooker support 100 of this application forms a heat-insulating cavity 12 inside the energy-concentrating ring 1. When the gas is ignited, a large amount of heat is generated and transferred to the energy-concentrating ring 1. The energy-concentrating ring 1 exchanges heat with the air inside the heat-insulating cavity 12, thus transferring heat to the air inside the heat-insulating cavity 12. Simultaneously, the energy-concentrating cooker support 100 of this application has a guide member 3 extending from the first side 13 to the second side 14 on the energy-concentrating ring 1, and the guide member 3 is at least partially located in the heat-insulating cavity 12. The air inlet 32 ​​of the guide member 3 is used to allow air to enter the guide cavity 31, and the air outlet 33 is located above the air inlet 32. When the air enters the guide cavity 31, it can exchange heat with the air inside the heat-insulating cavity 12, thereby preheating the external air before it is delivered to the combustion zone of the gas. In other words, the energy-concentrating pot support 100 of this application is set inside the heat insulation cavity 12 through the flow guide 3, so that the preheated air can recover and utilize the heat that was originally lost through the radiation of the wall of the energy-concentrating ring 1. The recovered heat is then transferred to the bottom of the pot or the gas combustion zone through the air, which can reduce the loss of gas heat and thus help improve the thermal efficiency of the gas.

[0094] Furthermore, the air inlet 32 ​​faces the second side 14 of the energy-concentrating ring 1. The air inlet 32 ​​is used to supply air into the guide cavity 31, and the air outlet 33 is connected to the guide cavity 31 and is located above the air inlet 32 ​​along the axial direction of the energy-concentrating ring 1. This forms a directional airflow channel. The air inlet 32 ​​draws in cold air from the second side 14 of the energy-concentrating ring 1, and delivers it through the guide cavity 31 to the upper air outlet 33. This allows fresh air to be delivered to the combustion zone, achieving air replenishment and promoting complete fuel combustion. This not only reduces the emission of harmful gases such as carbon monoxide, but also further improves thermal efficiency through complete combustion.

[0095] Secondly, the air inlet 32 ​​is located below the air outlet 33 along the axial direction of the energy-concentrating ring 1. When heating a pot with the gas stove 200 equipped with the energy-concentrating pot support 100, the temperature of the air outlet 33 is higher than that of the air inlet 32 ​​because it is closer to the gas flame. The hot air density is lower, which causes the air in the guide cavity 31 to flow upward continuously, so that the air outside the energy-concentrating pot support 100 can continuously enter the guide cavity 31, thereby ensuring the stability and continuity of the external air supply.

[0096] In some embodiments, the energy-concentrating ring 1 includes an inner wall 15 and an outer wall 16, with the outer wall 16 and the inner wall 15 disposed opposite each other in the radial direction of the energy-concentrating ring 1. The inner wall 15 is closer to the hollow portion 11 in the radial direction of the energy-concentrating ring 1 than the outer wall 16, and the air outlet 33 faces the inner wall 15.

[0097] By directing the air outlet 33 toward the inner wall 15 (i.e., toward the hollow portion 11 near the bottom of the cookware), the external air delivered by the guide element 3 can be precisely directed toward the core combustion area. This directional airflow not only replenishes oxygen for the combustion of the gas, but also generates an inward airflow thrust, helping the gas flame to converge toward the bottom of the cookware, reducing the loss of the gas flame as it diffuses outward, and further enhancing the heat-concentrating effect of the energy-concentrating ring 1.

[0098] Understandably, the air outlet 33 can face the inner wall 15, the second side 14, or diagonally upwards towards the bottom of the pot. All of these can supplement the area of ​​the flame combustion with external air. However, since the burner head 202 is usually located in the hollow part 11 of the energy-concentrating ring 1, the air outlet 33 facing the inner wall 15 can directly guide the external air to the core flame area of ​​the gas combustion, resulting in better complete combustion of the gas and higher thermal efficiency.

[0099] Optionally, please refer to Figures 6 to 9 , Figure 8 This is a schematic diagram of the structure of the flow guide provided in the embodiment of this application. Figure 9 for Figure 8 A cross-sectional view at point DD. In some embodiments, the flow guide 3 includes a first top plate portion 34, a first flow guide plate portion 35, and a second flow guide plate portion 36. One end of the first flow guide plate portion 35 is connected to the first top plate portion 34, and the other end of the first flow guide plate portion 35 extends to the second side 14 of the energy-concentrating ring 1. An air outlet 33 is provided at the end where the first flow guide plate portion 35 and the first top plate portion 34 are connected. Along the radial direction of the energy-concentrating ring 1, the first flow guide plate portion 35 is disposed close to the inner wall 15 so that the air outlet 33 faces the inner wall 15. The second flow guide plate portion 36 is disposed facing the first flow guide plate portion 35 along the radial direction of the energy-concentrating ring 1. One end of the second flow guide plate portion 36 is connected to the first top plate portion 34, and the other end of the second flow guide plate portion 36 extends to the second side 14 of the energy-concentrating ring 1. An air inlet 32 ​​is constructed between the other end of the second flow guide plate portion 36 and the other end of the first flow guide plate portion 35. Along the radial direction of the energy-concentrating ring 1, the second guide plate portion 36 is disposed near the outer wall 16. The first top plate portion 34, the first guide plate portion 35, and the second guide plate portion 36 together define the guide cavity 31.

[0100] The first guide plate 35 and the second guide plate 36 both extend from the first top plate 34 to the second side 14 (bottom) of the energy-concentrating ring 1, forming a complete airflow channel that runs through the heat insulation cavity 12. The air inlet 32 ​​is constructed from the gap between the ends of the two guide plates, which allows the opening area and angle of the air inlet 32 ​​to be precisely designed, thereby better adapting to the energy-concentrating pot support 100.

[0101] It is understood that the first guide plate portion 35, the second guide plate portion 36, and the first top plate portion 34 mentioned above can be separately manufactured and installed components, and then fixedly connected by welding or other methods. They can also be set as an integral component, that is, the guide member 3 is a whole integral structure. This embodiment does not specifically limit this.

[0102] Please see Figures 7 to 11 , Figure 8 for Figure 4 Cross-sectional view at point DD. Figure 9 for Figure 8 A magnified view of a portion of point E in the middle. Figure 10 for Figure 2 Cross-sectional view at the FF point. Figure 11 for Figure 10 A partially enlarged schematic diagram at point G. In some embodiments, the flow guide 3 includes a flanged portion 37 connected to the first flow guide plate portion 35 and the second flow guide plate portion 36 near the second side 14. The portion of the flanged portion 37 connected to the first flow guide plate portion 35 and the portion of the flanged portion 37 connected to the second flow guide plate portion 36 together define the aforementioned air inlet 32. The outer wall 16 includes an outer ring bottom wall 161 and an outer ring side wall 162. The outer ring side wall 162 is connected to the outer ring bottom wall 161, and a first clearance opening 1621 is provided on the side of the outer ring side wall 162 near the outer ring bottom wall 161. The first clearance opening 1621 communicates with the heat insulation cavity 12. The flow guide 3 passes through the first clearance opening 1621 so that the flanged portion 37 is located outside the first clearance opening 1621. The flange 37 is connected to the outer ring sidewall 162 and the outer ring bottom wall 161 so that the flow guide 3 is connected to the energy-concentrating ring 1.

[0103] The flanged portion 37 is connected to one end of the first guide plate portion 35 and the second guide plate portion 36 near the second side 14 (the side of the cooktop surface 201), and is connected to the outer ring side wall 162 and the outer ring bottom wall 161, respectively. Thus, along the axial direction of the energy-concentrating ring body 1, the connection between the flanged portion 37 and the outer ring bottom wall 161 restricts the upward or downward axial movement of the guide member 3. Along the radial direction of the energy-concentrating ring body 1, the connection between the flanged portion 37 and the outer ring side wall 162 prevents the guide member 3 from radially shifting towards the center (hollow portion 11) or the outer side of the energy-concentrating ring body 1. This ensures the stability of the guide member 3 during use.

[0104] Furthermore, the flow guide 3 is connected to the heat insulation cavity 12 via the first clearance opening 1621, with the flange 37 positioned outside the first clearance opening 1621. This allows the high-temperature environment within the heat insulation cavity 12 to preheat the air in the flow guide cavity 31 after the energy-concentrating ring 1 accumulates heat. When the preheated air is delivered to the combustion zone through the outlet 33, it reduces the temperature difference with the combustion gas, promoting faster combustion and improving combustion efficiency. The flange 37's position outside the first clearance opening 1621 prevents it from affecting the airflow within the flow guide cavity 31.

[0105] Optionally, the flange portion 37 can be an annular plate portion, which mainly extends outward from the ends of the first guide plate portion 35 and the second guide plate portion 36 near the second side to form an annular plate portion surrounding the air inlet 32. This allows the flange portion 37 to form a circumferential full-range connection with the outer ring sidewall 162 and the outer ring bottom wall 161. Furthermore, the extension shape and direction of the flange portion 37 are adapted to the shape of the outer ring sidewall 162 and the outer ring bottom wall 161. This maximizes the fit between the flange portion 37 and the outer ring sidewall 162 and the outer ring bottom wall 161, forming a surface contact rather than a point contact or line contact. This disperses the stress on the connection part, avoiding loosening of the connection or deformation of the component due to excessive local stress, thereby enhancing the stability and reliability of the connection between the guide member 3 and the energy-concentrating ring 1.

[0106] Secondly, the flanged portion 37 and the outer ring sidewall 162 and outer ring bottom wall 161 are surface-fitted, which reduces the connection gaps between the flanged portion 37 and the outer ring sidewall 162 and outer ring bottom wall 161. On the one hand, this prevents oil, dust and other impurities from entering the heat insulation cavity 12 through the gaps during use, reducing the overall cleaning difficulty of the energy-concentrating pot support 100. On the other hand, the tight fit also enhances the overall sealing of the energy-concentrating ring 1, preventing air from leaking out of the heat insulation cavity 12 from affecting the energy-concentrating and heat-insulating effect of the energy-concentrating ring 1.

[0107] It is understood that the flanged portion 37, the first guide plate portion 35, and the second guide plate portion 36 can be separately manufactured and installed components, and then fixedly connected by welding or other methods. Of course, they can also be set as an integral component, that is, the guide member 3 is a whole integral structure, and this embodiment does not specifically limit this.

[0108] Optionally, the flow guide 3 is detachably connected to the energy-concentrating ring 1, allowing the flow guide 3 and the energy-concentrating ring 1 to be assembled and disassembled separately. For example, the flow guide 3 and the energy-concentrating ring 1 can be detachably connected via, for example, a snap-fit ​​connection, or via, for example, a screw connection. Specifically, this can be achieved by the flange 37 being detachably connected to the outer ring sidewall 162 and the outer ring bottom wall 161, as will be described below.

[0109] After long-term use, the inside of the air guide cavity 31 is prone to accumulating oil stains (such as cooking fumes, soup splatter, etc.). The detachable connection between the flange 37 and the outer ring side wall 162 and the outer ring bottom wall 161 allows users or maintenance personnel to easily remove the air guide 3 and thoroughly clean the oil stains on the inner wall 15 of the air guide cavity 31 by rinsing, wiping, etc., to avoid the reduction of air intake or the displacement of the air outlet 33 due to oil stain blockage, and to ensure that the air guide 3 maintains the best working condition for a long time.

[0110] In addition, users can flexibly replace the air guide 3 with different specifications (e.g., the size of the air inlet 32 ​​opening, the orientation of the air outlet 33 opening, etc.) according to different usage scenarios, such as stir-frying which requires a larger air intake and stewing which requires a more stable small air flow. Of course, the air guide 3 can also be easily replaced when it is damaged, without having to discard the entire energy-concentrating pot support 100.

[0111] It is understandable that the detachable connection between the flanged portion 37 and the outer ring sidewall 162 and the outer ring bottom wall 161 can be achieved through snap-fit ​​connections. For example, protruding locking blocks can be pre-set at the bottom of the outer ring sidewall 162 and the bottom of the outer ring bottom wall 161, corresponding to matching slots or grooves 361 on the flanged portion 37. During assembly, the locking blocks are inserted into the slots by pressing the flanged portion 37, and the elastic deformation of the locking blocks and slots enables quick engagement. During disassembly, applying a reverse force will disengage the locking blocks from the slots. Alternatively, a detachable connection can be achieved using screws. Screw holes can be correspondingly provided on the flanged portion 37, the outer ring sidewall 162, and the outer ring bottom wall 161, and the three can be fastened together using self-tapping screws or machine screws.

[0112] In some embodiments, taking a snap-fit ​​connection as an example, a slot 361 is provided in the second guide plate portion 36, and the slot 361 and the flange portion 37 together form a hook portion 371. The side of the outer ring sidewall 162 near the outer ring bottom wall 161 engages with the hook portion 371, so that the flange portion 37 is connected to the outer ring sidewall 162. The flange portion 37 has an abutting surface, which abuts against the outer ring bottom wall 161 to connect the flange portion 37 and the outer ring bottom wall 161.

[0113] The hook portion 371 is constructed by the slot 361 of the second guide plate portion 36 and the flange portion 37, and engages with the side of the outer ring sidewall 162 near the bottom wall 161 of the outer ring. In this way, along the radial direction of the energy-concentrating ring body 1, the inner side of the hook portion 371 (the side near the hollow portion 11) can lock the edge of the outer ring sidewall 162, preventing the guide member 3 from shifting towards the center (hollow portion 11) of the energy-concentrating ring body 1, thereby avoiding the deviation of the air outlet 33 due to radial displacement. Along the axial direction of the energy-concentrating ring body 1, the hook portion 371, together with the flange portion 37, abuts against the bottom wall 161 of the outer ring, forming an axial fixation of the outer ring sidewall 162, preventing the guide member 3 from moving along the axial direction of the energy-concentrating ring body 1, thereby ensuring the stability of the guide member 3.

[0114] In addition, after the hook part 371 engages with the outer ring sidewall 162, it can tightly wrap the edge of the outer ring sidewall 162 and fill the connection gap. This can reduce the amount of oil and dust entering the heat insulation cavity 12 through the gap, and also prevent air from leaking out of the heat insulation cavity 12 through the gap, thus ensuring the heat-gathering effect of the heat-concentrating pot support 100.

[0115] In addition, the flanged part 37 abuts against the bottom wall 161 of the outer ring by the contact surface and engages with the side wall 162 of the outer ring by the hook part 371. When it is necessary to replace the energy-concentrating ring body 1 or the flow guide 3, the two can be quickly disassembled and replaced without replacing the whole body, which helps to reduce the component replacement cost of the energy-concentrating pot support 100.

[0116] Optionally, the two ends of the flow guiding cavity 31 are the air inlet 32 ​​and the air outlet 33, respectively. Along the direction from the first side 13 to the second side 14, the first flow guiding plate portion 35 is inclined towards the side closer to the outer wall 16, and the second flow guiding plate portion 36 is also inclined towards the side closer to the outer wall 16. The inclination angle of the second flow guiding plate portion 36 in the axial direction of the energy-concentrating ring 1 is greater than the inclination angle of the first flow guiding plate portion 35 in the axial direction of the energy-concentrating ring 1, so that the flow guiding cavity 31 is widened at the air inlet 32.

[0117] Along the direction from the first side 13 (cookware side) to the second side 14 (stovetop side), both the first guide plate portion 35 and the second guide plate portion 36 are inclined towards the side closer to the outer wall 16, with the second guide plate portion 36 having a larger inclination angle, thus widening the air inlet 32. The widened air inlet 32 ​​can capture air from a wider area, ensuring that more air can be delivered to the guide cavity 31 and then to the combustion zone, thereby avoiding interruption of gas combustion or decrease in combustion efficiency due to insufficient air supply.

[0118] Optionally, the area of ​​the air inlet 32 ​​is larger than the area of ​​the air outlet 33.

[0119] According to the fluid continuity equation (flow rate = cross-sectional area × velocity), when the air flow rate is stable, the smaller the cross-sectional area, the greater the velocity. The area of ​​the air inlet 32 ​​is larger than that of the air outlet 33. This means that after external air enters the guide cavity 31 from the air inlet 32, the reduced cross-sectional area leads to an increased velocity, thus quickly delivering the external air to the combustion zone. This prevents air from stagnating in the guide cavity 31, ensuring timely oxygen replenishment in the combustion zone.

[0120] Optionally, the energy-concentrating pot support 100 also includes a filter (not shown in the figure), which is disposed at the air inlet 32 ​​to filter the air passing through the air inlet 32.

[0121] In a kitchen environment, the air contains dust, oil fume particles, and cooking residue (such as flour and vegetable scraps). If these particles enter the airflow chamber 31 directly, they easily adhere to the inner wall 15 of the airflow deflector plate, and long-term accumulation can clog the airflow chamber 31. By installing a filter at the air inlet 32 ​​to filter the air passing through it, external impurities can be prevented from entering the airflow chamber 31, thus avoiding blockage and affecting the airflow guiding effect of the airflow deflector 3.

[0122] It is understood that the above-mentioned filter element can be a metal filter screen or a ceramic filter sheet, etc., and this embodiment does not specifically limit it.

[0123] Optionally, the energy-concentrating pot support 100 also includes a heat insulation layer (not shown in the figure), and at least one of the first guide plate portion 35 and the second guide plate portion 36 is provided with a heat insulation layer on the surface opposite to the guide cavity 31.

[0124] The flow guide cavity 31 is used to transport secondary air. When the energy-concentrating ring 1 accumulates heat, the high temperature inside the insulation cavity 12 heats the air inside the flow guide cavity 31 through the first flow guide plate 35 and the second flow guide plate 36. However, overheating may cause the air to expand, thus reducing the oxygen content per unit volume. By setting an insulation layer, it is possible to prevent insufficient heat from affecting the combustion efficiency of the gas in the flow guide cavity 31, and also to prevent the air transported by the flow guide cavity 31 from being overheated, leading to a decrease in oxygen concentration.

[0125] It is understood that the above-mentioned insulation layer can be ceramic fiber cotton or silicone rubber insulation cotton, etc., and this embodiment does not specifically limit it.

[0126] Optionally, at least one of the first guide plate portion 35 and the second guide plate portion 36 has a surface facing away from the guide cavity 31 that is configured as a non-flat surface.

[0127] By constructing at least one of the surfaces of the first guide plate portion 35 and the second guide plate portion 36 that are away from the guide cavity 31 as a non-flat surface, the contact area between the first guide plate portion 35 and the second guide plate portion 36 and the air in the heat insulation cavity 12 can be increased, thereby improving the heat exchange effect between the air in the guide cavity 31 and the air in the heat insulation cavity 12, and ensuring that the air transported by the guide cavity 31 can be fully heated.

[0128] It is understood that the above-mentioned uneven surface refers to the situation where at least one of the first guide plate portion 35 and the second guide plate portion 36 is uneven or non-flat. Such a surface may have unevenness, curvature, twisting or other irregular shapes. For example, multiple protrusions may be provided at intervals on the surface, or a honeycomb structure may be provided on the surface. This embodiment does not specifically limit this.

[0129] Please see also Figures 8 to 11 In some embodiments, the energy-concentrating ring 1 includes an inner ring 17, a second top plate portion 18, and an outer ring 19. The second top plate portion 18 and the inner ring 17 are connected. The outer ring 19 is connected to the inner ring 17 on one side along the axial direction of the energy-concentrating ring 1, and to the second top plate portion 18 on the other side along the axial direction of the energy-concentrating ring 1, so that the outer ring 19, the inner ring 17, and the second top plate portion 18 together form a heat insulation cavity 12. A second clearance opening 171 is provided on the side of the inner ring 17 connected to the second top plate portion 18. The second clearance opening 171 communicates with the heat insulation cavity 12 and is configured to allow the flow guide 3 to pass through.

[0130] The second clearance opening 171 is located at the connection between the inner ring body 17 and the second top plate portion 18, near the bottom of the pot. When the guide member 3 is inserted through the second clearance opening 171, its air outlet 33 is also near the bottom of the pot, thus allowing external air to be delivered to the flame, resulting in more complete combustion of the gas. Simultaneously, since the outer ring body 19, inner ring body 17, and second top plate portion 18 together form a heat insulation cavity 12, the second clearance opening 171 ensures that the integrity of the heat insulation cavity 12 is not compromised, thereby guaranteeing that the entire energy-concentrating ring support can simultaneously achieve the dual purposes of secondary air replenishment and heat insulation.

[0131] It is understood that the inner ring 17 and the outer ring 19 are two annular components, with the inner ring 17 forming the inner boundary of the hollow portion 11 and simultaneously constructing the inner wall of the insulation cavity 12. The outer ring 19 forms the outer boundary of the hollow portion 11 and simultaneously constructs the outer wall of the insulation cavity 12. The second top plate portion 18 is an annular flat plate, which is also the top cover plate used to close the insulation cavity 12. In this way, the second top plate portion 18, the outer ring 19, and the inner ring 17 are connected in sequence to form the top boundary and the inner boundary of the insulation cavity 12.

[0132] In some embodiments, the outer ring 19 has the aforementioned outer ring sidewall 162 and outer ring bottom wall 161, wherein the outer ring sidewall is a vertical sidewall forming the outer vertical boundary of the heat insulation cavity 12, and the outer ring bottom wall 161 is a horizontal sidewall forming the bottom boundary of the heat insulation cavity 12. Thus, the second top plate portion 18, the outer ring sidewall 162, the outer ring bottom wall 161, and the inner ring 17, connected end-to-end in sequence, together form the entire energy-concentrating ring 1, while simultaneously defining the heat insulation cavity 12 within it.

[0133] Please see Figure 12 , Figure 12 This is a schematic diagram of the structure of a gas stove provided in an embodiment of this application. A second aspect of this application discloses a gas stove 200, including the energy-concentrating pot support 100 from any of the above embodiments.

[0134] A gas stove 200 typically includes a countertop 201, on which a burner 202 is mounted for igniting gas. A pot-concentrating support 100 is arranged around the outside of the burner 202, so that the burner 202 is located in the hollow portion 11 of the pot-concentrating ring 1, allowing the pot to be heated by the flame when placed on the support legs 2. In this way, during the use of the gas stove 200, the pot-concentrating support 100 reduces heat loss from the gas at the burner 202. Simultaneously, the guide element 3 of the pot-concentrating support 100 delivers external air to the combustion zone, improving gas combustion efficiency. Furthermore, the external air is preheated within the guide cavity 31, thus recovering and delivering heat from the gas to the combustion zone or the bottom of the pot, thereby improving the thermal efficiency of the gas stove 200.

[0135] The above provides a detailed description of the energy-efficient pot support and gas stove disclosed in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the energy-efficient pot support and gas stove of this application and their core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
