Description

Technical Field

[0001] The present invention relates to the technical field of stoves, and in particular to a gas stove. Background Art

[0002] A gas stove refers to a kitchen appliance that uses petroleum gas, artificial gas, natural gas and other gases as fuel for heating.

[0003] The main components of a gas stove's combustion system include the ejector tube, injection device, burner, and flame cap. Fuel burns through the flame holes in the flame cap, heating the bottom of the pot. To reduce heat radiation from the flame into the surrounding air and minimize heat loss, the gas stove also includes a heat concentrator.

[0004] During the flow of high-temperature flue gas between the bottom of the pot and the energy-gathering plate, laminar flow is easily formed at the bottom of the pot and on the surface of the energy-gathering plate, affecting the heat exchange between the high-temperature flue gas and the bottom of the pot, thereby affecting the thermal efficiency of the gas stove. Summary of the Invention

[0005] The object of the present invention is to provide a gas stove, aiming to solve the problem of laminar flow of high-temperature smoke at the bottom of the cookware and on the surface of the energy-gathering plate.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The present invention provides a gas stove comprising a base, a burner, a panel, and a heat sink. The base defines an opening for a mounting cavity. The burner is disposed within the base cavity. The panel cover is mounted on the base. The heat sink is an annular structure, disposed on the side of the panel facing away from the base. A spoiler is formed on the surface of the heat sink facing away from the panel. The spoiler extends circumferentially around the heat sink and serves to improve the heat exchange efficiency between high-temperature flue gas and the bottom of the cookware.

[0008] When a gas stove burns fuel, generating flames and high-temperature flue gas, the hot flue gas flows along the bottom of the cookware, exchanging heat with it. Simultaneously, the hot flue gas flows along the side of the concentrating plate closest to the bottom of the cookware. As the hot flue gas flows along the concentrating plate near the bottom of the cookware, it passes through the flow spoiler, which disrupts the hot flue gas, creating turbulent flow.

[0009] This prevents the high-temperature flue gas from flowing in a laminar flow on the side of the energy-gathering disk away from the panel. Instead, it tends to form turbulent flow as it moves from the center of the energy-gathering disk toward its outer ring. Turbulent flow is characterized by disordered movement and intermixing of the fluids. The intense mixing and vortexing in turbulent flow improves heat transfer efficiency, resulting in a higher heat exchange efficiency between the high-temperature flue gas and the bottom of the cookware compared to laminar flow.

[0010] In addition, when the high-temperature flue gas in a turbulent state after being disturbed by the spoiler flows to the bottom of the cookware, due to the disordered and diffusive movement characteristics of the turbulent flow, the high-temperature flue gas in a turbulent state after being disturbed will be mixed to a certain extent with the flue gas in a laminar state at the bottom of the cookware. This can destroy the existing laminar state of the flue gas at the bottom of the cookware, so that the subsequently generated high-temperature flue gas can contact and exchange heat with the bottom of the cookware faster, thereby improving the heat exchange efficiency.

[0011] In some embodiments, the gas stove further comprises a pot support, which comprises a plurality of legs. The energy concentrating plate is provided with a through hole, the legs are passed through the through hole, and the legs are connected to the energy concentrating plate, and a spoiler is provided between two adjacent legs.

[0012] In some embodiments, along the circumference of the energy concentrating disk, there is a distance between the two ends of the spoiler and adjacent supporting feet.

[0013] In some embodiments, the energy concentrating disk includes a first disk body, and a spoiler is provided on a surface of the first disk body away from the panel. The spoiler and the first disk body are integrally formed by a stamping process, and the spoiler is raised in a direction away from the panel.

[0014] In some embodiments, a projection of the spoiler on a plane perpendicular to the panel has a polygonal outline.

[0015] In some embodiments, the spoiler includes two first connecting plates and at least one second connecting plate. One end of the two first connecting plates is connected to a surface of the first plate away from the panel; the other end of the two first connecting plates is connected to the at least one second connecting plate. The angle formed between one of the two first connecting plates, which is closer to the center of the first plate, and the surface of the first plate away from the panel, is an obtuse angle.

[0016] In some embodiments, there are multiple spoilers, and the multiple spoilers are arranged along the radial direction of the energy focusing disk.

[0017] In some embodiments, the surface of the energy concentrating disk on the side away from the panel is inclined, and the distance between the surface of the energy concentrating disk on the side away from the panel and the panel gradually increases as it moves away from the center of the energy concentrating disk. In the radial direction of the energy concentrating disk and away from the center of the energy concentrating disk, the distance between one end of the plurality of spoilers on the side away from the panel and one end of the surface of the energy concentrating disk on the side away from the panel remains constant or gradually increases.

[0018] In some embodiments, the distances between the highest points of the plurality of spoilers and the panel are all less than or equal to the distance between the highest point of the energy concentrating disk and the panel.

[0019] In some embodiments, the first plate has an inner side and an outer side, and the spoiler is disposed between the inner side and the outer side of the first plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the present invention. Unless otherwise specified, the above-mentioned directions may be flexibly set in actual application, provided that the relative positional relationships shown in the accompanying drawings are met.

[0045] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0046] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "communicated" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections. They may be directly connected, indirectly connected through an intermediary, or internally connected between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0047] In embodiments of the present invention, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, article, or apparatus comprising the element.

[0048] In the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present invention should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0049] This application provides a gas stove, such as Figure 1 As shown, Figure 1 This is a schematic diagram of a gas stove 100 provided in this application. The gas stove 100 may include a bottom housing 11, which defines a mounting cavity 10 with an opening. The opening communicates with the mounting cavity 10, allowing other components of the gas stove 100 to be installed within the mounting cavity 10 of the bottom housing 11. The bottom housing 11 provides support and a degree of protection for the components installed within the mounting cavity 10, ensuring proper operation of the gas stove 100.

[0050] On this basis, see Figure 1The gas stove 100 provided herein also includes a burner 2, which is a core component of the gas stove 100. The burner 2 is disposed in the mounting cavity 10 of the bottom housing 11. The burner 2 allows fuel and primary air to be mixed in a certain manner. The mixed gas formed by the fuel and primary air flows out of the burner 2 and is ignited to form a flame, which heats the bottom of the cookware.

[0051] like Figure 1 As shown, the gas stove 100 provided in this application may further include a panel 12. The panel 12 is disposed over the opening of the bottom housing 11 and serves to seal the mounting cavity 10 of the bottom housing 11. This prevents debris or food residue dropped during cooking from falling into the mounting cavity 10 of the bottom housing 11, thereby preventing damage or contamination to components disposed in the mounting cavity 10, thereby ensuring the proper functioning of the gas stove 100.

[0052] In this case, if Figure 1 As shown, the panel 12 also defines a clearance opening 120. The burner 2 is positioned directly opposite the clearance opening 120, allowing the burner 2 to be positioned within the opening of the clearance opening 120. This ensures that when the burner 2 burns fuel and produces a flame, the panel 12 does not obstruct the flame, ensuring that the burner 2 can function properly and heat the bottom of the cookware, allowing the user to continue cooking.

[0053] As can be seen from the above, a gas stove 100 provided in an embodiment of the present application may include a bottom shell 11, a panel 12, and a burner 2, the core component of the gas stove 100. The burner 2 may be installed in the mounting cavity 10 of the bottom shell 11, and the mounting cavity 10 of the bottom shell 11 may be covered by the panel 12 to protect other components disposed in the mounting cavity 10, thereby preventing the burner 2 and other components from being damaged, thereby ensuring that the gas stove 100 can function properly.

[0054] like Figure 2 As shown, the gas stove 100 provided in the present application may further include an energy collecting plate 3. This energy collecting plate 3 is an annular structure and is disposed on the side of the panel 12 away from the bottom housing 11. The center of the annular energy collecting plate 3 is a hollow structure, and the hollow structure of the energy collecting plate 3 is arranged directly opposite the avoidance opening 120 provided in the panel 12. In this way, the flame generated by the burner 2 burning fuel can be located in the hollow structure of the energy collecting plate 3. The energy collecting plate 3 can isolate the radiation and convection heat exchange between the burning flame and the surrounding air, reducing heat loss and improving the thermal efficiency of the gas stove 100.

[0055] It should be noted that the energy collecting disk 3 can be as follows: Figure 2The circular ring structure shown can also be other ring structures, for example, a square ring structure. Figure 3 In some other embodiments of the present application, the energy gathering disk 3 may be a square ring structure, and the periphery of the energy gathering disk 3 of the square ring structure is chamfered.

[0056] However, in the area at the bottom of the pot, when the high-temperature flue gas just leaves the flame contact surface, the speed of the high-temperature flue gas is relatively low. If the speed of the high-temperature flue gas is not enough to break the laminar critical speed, a laminar flow state will easily form at the bottom of the pot.

[0057] In addition, there is friction resistance between the high-temperature flue gas and the bottom surface of the pot, which makes it easy for the high-temperature flue gas to form a boundary layer when flowing near the bottom of the pot. The high-temperature flue gas flow in the boundary layer usually exhibits laminar characteristics.

[0058] In laminar flow, there are few intermolecular collisions and low shear stress, so heat transfer relies primarily on conduction and natural convection. Due to the low degree of mixing within laminar flow, the heat exchange rate can be slower than in turbulent flow, resulting in relatively low heat transfer efficiency.

[0059] After exchanging heat with the bottom of the cookware, the high-temperature flue gas cools down, increases in density, and sinks downward. This can cause stratification between the relatively high-temperature flue gas and the relatively low-temperature flue gas. It's understandable that the flue gas at the bottom of the cookware, which has cooled after heat exchange, will, to a certain extent, affect the subsequent heat exchange between the high-temperature flue gas and the bottom of the cookware.

[0060] The energy concentrating plate 3 provided in the present application also has a spoiler, which is used to improve the heat exchange efficiency between the high-temperature flue gas and the bottom of the cookware. The energy concentrating plate 3 and the spoiler of the present application will be further described below with reference to the accompanying drawings.

[0061] Take the energy collecting disk 3 as an example. Figure 4 As shown, the surface of the energy concentrating disk 3 away from the panel 12 has the above-mentioned spoiler 4, which extends along the circumference of the energy concentrating disk 3. The spoiler 4 is used to improve the heat exchange efficiency between the high-temperature smoke and the bottom of the cookware.

[0062] It should be noted that, when the energy gathering disk 3 is a square annular structure, the spoiler 4 can also be provided along the circumference of the square annular energy gathering disk 3 .

[0063] When the gas stove 100 burns fuel, generating flames and high-temperature flue gas, the high-temperature flue gas will flow along the bottom of the cookware, exchanging heat with the bottom of the cookware. Simultaneously, the high-temperature flue gas will flow along the surface of the concentrating plate 3 near the bottom of the cookware. When the high-temperature flue gas flowing along the surface of the concentrating plate 3 near the bottom of the cookware passes through the spoiler 4, the spoiler 4 will disturb the high-temperature flue gas, causing it to change its direction of flow. For example, the high-temperature flue gas originally flowing along the surface of the concentrating plate 3 may flow away from the concentrating plate 3 toward the bottom of the cookware, or in other directions, thereby forming turbulent flow.

[0064] As a result, the high-temperature flue gas on the side of the energy-gathering disk 3 away from the panel 12 is less likely to flow in a laminar state. Instead, it tends to form turbulent flow as it flows from the center of the energy-gathering disk 3 toward its outer ring. Turbulent flow is characterized by disordered movement and intermixing of the fluids. The intense mixing and vortexing in turbulent flow improves heat exchange efficiency, resulting in a higher heat exchange efficiency between the high-temperature flue gas and the bottom of the cookware compared to laminar flow.

[0065] In addition, when the high-temperature flue gas in a turbulent state after being disturbed by the spoiler 4 flows toward the bottom of the cookware, due to the disordered and diffusive movement characteristics of the turbulent flow, the high-temperature flue gas in a turbulent state after being disturbed will be mixed to a certain extent with the flue gas in a laminar state at the bottom of the cookware. This can destroy the existing laminar state of the flue gas at the bottom of the cookware, so that the subsequently generated high-temperature flue gas can contact the bottom of the cookware and exchange heat more quickly, thereby improving the heat exchange efficiency.

[0066] like Figure 5 As shown, in some embodiments of the present application, the spoiler 4 can also be arranged in a wavy shape. In this way, the wavy spoiler 4 can further enhance the disturbing effect of the spoiler 4 on the high-temperature flue gas, making the turbulence formed by the high-temperature flue gas more intense, thereby better exchanging heat with the bottom of the pot, and improving the thermal efficiency of the gas stove.

[0067] In some embodiments of the present application, Figure 6 As shown, along the radial direction of the energy concentrating disk 3, the distance between the spoiler 4 and the center of the energy concentrating disk 3 is greater than or equal to 100 mm, that is, the distance between the spoiler 4 and the center point of the energy concentrating disk 3 is above 100 mm.

[0068] In this way, the spoiler 4 can avoid the intense heat exchange area between the flame and the bottom of the pot. Firstly, the lifting effect is not great. In addition, the spoiler 4 is set too close to the center of the energy collecting disk 3, which affects the stability of the flame combustion reaction and affects the smoke index.

[0069] In some embodiments of the present application, Figure 7As shown, the gas stove provided herein also includes a pot support, which includes multiple legs 51. This pot support is placed on the stove panel, above the burner. When cooking, the user can place the pot on the legs 51 at the end of the pot support 1 away from the panel, providing support for the pot. The pot support also supports the energy concentrating plate 3.

[0070] Continue to see Figure 7 The energy collecting plate 3 is provided with a through hole 30, and the legs 51 of the pot support can be inserted into the through hole 30 of the energy collecting plate 3. The legs 51 of the pot support are connected to the energy collecting plate 3. In this case, a spoiler 4 is provided between two adjacent legs 51 of the pot support.

[0071] Exemplarily, the number of the legs 51 of the pot support can be four. Based on this, the number of the through holes 30 opened on the energy gathering disk 3 is also four, so that one leg 51 corresponds to one through hole 30.

[0072] When assembling the pot support and the energy concentrating disk 3, the pot support legs 51 can be first inserted into the through holes 30. The pot support legs 51 can then be connected and fixed to the energy concentrating disk 3 by welding. It should be noted that in addition to welding, adhesive bonding or other methods can also be used to fix the pot support and the energy concentrating disk 3.

[0073] See also Figure 8 , Figure 8 : is an assembly diagram of the support legs 51 of the pot support and the energy gathering plate 3. In some embodiments of the present application, along the circumference of the energy gathering plate 3, there is a gap between the two ends of the spoiler 4 and the adjacent support legs 51.

[0074] This allows the spoiler 4 to avoid the through-hole 30 in the energy concentrating disk 3 and, in turn, the legs 51 of the pot support connected to the energy concentrating disk 3, facilitating the machining of the through-hole 30 in the energy concentrating disk 3. Furthermore, the spacing between the ends of the spoiler 4 and the legs 51 facilitates the secure connection between the pot support and the energy concentrating disk 3.

[0075] For example, when the energy concentrating disk 3 and the pot support are fixed by welding, the spacing between the spoiler 4 and the support leg 51 allows the pot support and the energy concentrating disk 3 to be welded without the spoiler 4. In this way, when welding is used for connection and fixation, only the energy concentrating disk 3 and the support leg 51 of the pot support need to be welded, while the spoiler 4, which has a relatively complex welding connection point, is avoided.

[0076] The energy collecting disk 3 provided by the present application is further described below with reference to the accompanying drawings. Figure 8As shown, the energy concentrating plate 3 includes a first plate body 31. The first plate body 31 is annular, with a spoiler 4 disposed on the surface of the first plate body 31 facing away from the panel 12. The spoiler 4 and the first plate body 31 are integrally formed through a stamping process, and the spoiler 4 protrudes away from the panel. In other words, the spoiler 4 protrudes toward the bottom of the cookware, thereby disturbing the high-temperature flue gas as it flows through the spoiler 4.

[0077] In other embodiments of the present application, see Figure 9 The spoiler 4 and the first plate 31 can also be formed separately and then assembled, and the spoiler 4 is installed on the surface of the first plate 31 near the bottom of the pot. Based on this, the spoiler 4 and the first plate 31 can be fixed by welding.

[0078] In other embodiments, the spoiler 4 can be connected and fixed with a threaded connection. For example, a screw is provided on the surface of the spoiler 4 near the energy-gathering disk 3, and then the screw passes through the first disk body 31. A nut is then provided on the side of the first disk body 31 away from the spoiler 4, and the nut is threadedly connected to the screw to secure the spoiler 4 to the first disk body 31.

[0079] like Figure 10 As shown, the energy collecting disk 3 provided by the present application may further include a second disk body 32, and the second disk body 32 is an annular structure. The first disk body 31 is connected to the second disk body 32, and see Figure 11 A cavity 300 is formed between the first plate 31 and the second plate 32. This double-layered structure further enhances the heat insulation of the energy-concentrating plate 3. This further reduces heat loss by radiating the heat generated by the flame and exchanging heat with the air, thereby improving the thermal efficiency of the gas stove.

[0080] On this basis, if Figure 12 As shown, in some embodiments of the present application, the energy concentrating disk 3 further includes a partition plate 33, which is disposed in the cavity 300. The partition plate 33 can be connected and fixed to the first disk body 31 and the second disk body 32 by welding or crimping.

[0081] When the heat generated by the flame is transferred into the cavity 300 of the energy concentrating disk 3 through the first disk body 31, the partition plate 33 located within the cavity 300 can divide the cavity 300 of the energy concentrating disk 3 into two cavities. As a result, when heat is transferred into the cavity 300 through the first disk body 31, the partition plate 33 located within the cavity 300 can reduce the conduction of heat to the second disk body 32, thereby reducing the radiation of heat from the second disk body 32 to the air and reducing heat loss.

[0082] Based on this, in other embodiments of the present application, the number of the above-mentioned partition plates 33 can also be multiple, and the multiple partition plates 33 are arranged in the cavity 300 of the energy concentrating disk 3, and the multiple partition plates 33 are arranged at intervals.

[0083] For example, the number of the partition plates 33 may be two, as shown in FIG. Figure 13 As shown, two partition plates 33 are spaced apart within the cavity 300 of the energy concentrating disk 3. When heat is transferred into the cavity 300 of the energy concentrating disk 3 through the first disk body 31 of the energy concentrating disk 3, the two partition plates 33 spaced apart within the cavity 300 can divide the cavity 300 of the energy concentrating disk 3 into three compartments. As a result, when heat is transferred into the cavity 300 through the first disk body 31, the two partition plates 33 within the cavity 300 can further reduce heat conduction to the second disk body 32, thereby reducing heat radiation from the second disk body 32 to the air and minimizing heat loss.

[0084] On a plane perpendicular to the panel 12, the outline of the projection of the spoiler 4 is a polygon, that is, the shape of the cross-section of the spoiler 4 along the direction perpendicular to the panel 12 is a polygon. Figure 14 As shown, in some embodiments, the outline of the projection of the spoiler 4 on a plane perpendicular to the panel 12 may be a triangle.

[0085] In this way, when the high-temperature flue gas flows through the triangular flow-turbulating portion 4, the high-temperature flue gas can be disturbed, thereby accelerating the heat exchange between the flue gas and the bottom of the cookware.

[0086] Next, the above-mentioned spoiler 4 will be further described. Figure 15 As shown, the spoiler 4 includes two first connecting plates 41 and at least one second connecting plate 42. One end of the two first connecting plates 41 is connected to the surface of the first plate 31 away from the panel 12, and the other end of the two first connecting plates 41 is connected to the at least one second connecting plate 42.

[0087] In some embodiments of the present application, the number of the second connecting plate 42 can be one, one end of the two first connecting plates 41 is connected to the surface of the first plate 31 away from the panel 12, and the other end of the two second connecting plates 41 is connected to the second connecting plate 42. In this case, the cross-sectional shape of the spoiler 4 is a trapezoid (see Figure 15 ).

[0088] In other embodiments of the present application, the number of the second connecting plates 42 can also be two. One end of the two first connecting plates 41 is connected to the surface of the first disk 31 away from the panel 12. The two second connecting plates 42 are located between the two first connecting plates 41, and the other ends of the two first connecting plates are respectively connected to a second connecting plate 42, and the ends of the two second connecting plates 42 that are close to each other are connected. Figure 16 As shown, the cross-sectional shape of the spoiler 4 is "M"-shaped. When the high-temperature flue gas flows through the "M"-shaped spoiler 4, it will pass through the two protrusions of the M-shaped spoiler 4, and the high-temperature flue gas will be disturbed multiple times.

[0089] On this basis, the angle formed between the center of the two first connecting plates 41 that is relatively closer to the center of the first plate 31 and the surface of the first plate 31 that is away from the panel 12 is an obtuse angle. For example, the spoiler 4 is projected in a triangular shape on a plane perpendicular to the panel 12.

[0090] In some embodiments of the present application, the angle between the first connecting plate 41 of the two first connecting plates 41 of the spoiler 4, which is closer to the center of the energy-concentrating plate 3, and the first plate body 31 can be 95 degrees. In this way, when the high-temperature flue gas flowing along the first plate body 31 contacts the first connecting plate 41 of the spoiler 4, the resistance to the high-temperature flue gas can be reduced, thereby preventing the high-temperature flue gas from losing too much kinetic energy after flowing through the spoiler 4, which would prevent the high-temperature flue gas from reaching the bottom of the cookware and exchanging heat with the cookware.

[0091] In other implementations of the present application, the obtuse angle may also be 100°, 105°, 110°, etc.

[0092] In some embodiments of the present application, the number of the spoilers 4 is multiple, and the multiple spoilers 4 are arranged along the radial direction of the energy-gathering disk 3. For example, the number of the spoilers 4 can be three (see Figure 10 ), the three spoilers 4 are arranged along the radial direction of the energy focusing disk 3. In this way, when the high-temperature flue gas flows along the surface of the energy focusing disk 3, it can pass through the three spoilers 4 in sequence, thereby ensuring that the high-temperature flue gas can be fully disturbed.

[0093] like Figure 17 As shown, in some other embodiments of the present application, the number of the spoilers 4 can also be four, and the four spoilers 4 are arranged along the radial direction of the energy concentrating disk 3. In this way, when the high-temperature flue gas flows along the surface of the energy concentrating disk 3, it can pass through the four spoilers 4 in sequence, thereby further ensuring that the high-temperature flue gas can be fully disturbed.

[0094] When there are multiple spoilers 4, the distance between adjacent spoilers 4 along the surface of the energy concentrating disk 3 away from the panel 12 is L. In some embodiments, the shortest distance L between adjacent spoilers 4 can be 0, that is, the first connecting plates 41 of two adjacent spoilers 4 that are close to each other are in contact.

[0095] In other embodiments, when there are multiple spoilers 4, the distance L between adjacent spoilers 4 along the surface of the energy concentrating disk 3 away from the panel 12 is greater than zero. That is, a gap exists between two adjacent spoilers 4. To avoid the turbulent effects of two adjacent spoilers 4 being offset by being too close, or the turbulent effects being weakened by being too far apart, a value of 1.5 mm ≤ L ≤ 3.0 mm can be employed. For example, the distance between two adjacent spoilers 4 can be 1.5 mm, 2 mm, or 3.0 mm.

[0096] In some embodiments of the present application, the height of the spoiler 4 relative to the first plate 31 should not be too high, as this would significantly obstruct the flow of smoke. The height of the spoiler 4 relative to the first plate 31 should also not be too low, as this would weaken the disturbance of the smoke. Therefore, the height of the spoiler 4 relative to the first plate 31 can be greater than or equal to 2.0 mm and less than or equal to 3.5 mm.

[0097] For example, the height of the spoiler 4 relative to the first plate 31 may be 2 mm, 2.5 mm, 3.0 mm, or 3.5 mm.

[0098] The surface of the energy gathering disk 3 away from the panel 12 is an inclined surface. As it moves away from the center of the energy gathering disk 3, the distance between the surface of the energy gathering disk 3 away from the panel 12 and the panel 12 gradually increases, that is, the energy gathering disk 3 is an inclined surface.

[0099] On this basis, along the radial direction of the energy concentrating disk 3 and away from the center of the energy concentrating disk 3, the distance between the end of the surface of the energy concentrating disk 3 away from the panel 12 and the end of the surface of the energy concentrating disk 3 away from the panel 12 remains constant or gradually increases. In other words, with the surface of the energy concentrating disk 3 away from the panel 12 as a reference, the height of the spoilers 4 on the energy concentrating disk 3 gradually increases along the radial direction of the energy concentrating disk 3, forming a stepped arrangement.

[0100] In this way, when the high-temperature flue gas flows from the center to the periphery of the energy focusing disk 3 along the energy focusing disk 3, after the high-temperature flue gas flows through the spoiler 4 close to the center of the energy focusing disk 3, since the spoiler 4 is arranged in a stepped manner along the energy focusing disk 3, the height of the spoiler gradually increases from the inside to the outside, so that the high-temperature flue gas after disturbance can be disturbed again by the spoiler 4 relatively close to the outside, thereby improving the disturbance effect, thereby improving the heat exchange efficiency between the high-temperature flue gas and the bottom of the cookware.

[0101] In some embodiments of the present application, the distance between the highest point of each of the spoilers 4 and the panel 12 is less than or equal to the distance between the highest point of the energy concentrating disk 3 and the panel 12. That is, each of the spoilers 4 is no higher than the energy concentrating disk 3. This ensures that when the spoilers 4 disturb the high-temperature flue gas, they do not block the exhausted flue gas from being discharged through the energy concentrating disk 3 and the bottom of the cookware. Furthermore, the spoilers 4 do not block the entry of secondary air through the gap between the bottom of the cookware and the energy concentrating disk 3, thereby ensuring sufficient combustion of the fuel.

[0102] In some embodiments of this application, see Figure 10 The first plate body 31 has an inner side edge 311 and an outer side edge 312 , and the spoiler 4 is disposed between the inner side edge 311 and the outer side edge 312 of the first plate body 31 .

[0103] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0104] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
