[0045] The present application proposes an energy-gathering disk, which is applied to a gas device provided with a burner 1000. The gas device may be a gas stove, or a combination of a gas stove and other electrical appliances, or other devices in which the burner 1000 is applied. The energy-gathering disk will be described in detail below using the gas stove as an example.

[0046] Combination Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments of the present application, the energy-gathering disk includes a second disk body 3000 and a first disk body 2000, the second disk body 3000 is used to be arranged around the first disk body 2000, an outer cavity 3100 is formed between the second disk body 3000 and the first disk body 2000, the outer cavity 3100 is open, and the first disk body 2000 surrounds an inner cavity 2100, so that the first disk body 2000 can be arranged around the burner 1000, and at least a part of the high-temperature flue gas generated by the burner 1000 can enter the outer cavity 3100, and the first disk body 2000 is gradually expanded, and along the gradually expanding direction of the first disk body 2000, at least two outer concave cavities 2220 are provided on one side of the first disk body 2000 facing the outer cavity 3100.

[0047] By forming an outer cavity 3100 between the second plate 3000 and the first plate 2000, the outer cavity 3100 forms heat insulation for the inner cavity 2100, and to a certain extent prevents the heat of the inner cavity 2100 from being lost through conduction of the first plate 2000. When the high-temperature flue gas generated by the burner 1000 flows out of the inner cavity 2100, at least a part of it can enter the outer cavity 3100, so that the outer cavity 3100 is also heated, which facilitates the heat to be transferred back to the heated object 6000.

[0048] In addition, an outer concave cavity 2220 is provided on the side of the first disk body 2000 facing the outer cavity 3100. The high-temperature flue gas entering the outer cavity 3100 can form a vortex when flowing through the outer concave cavity 2220, so that the high-temperature flue gas in the outer cavity 3100 can flow more fully and extend the flow path of the high-temperature flue gas, which is equivalent to the high-temperature flue gas entering the outer cavity 3100 having a longer time to exchange heat with the heated object 6000, making full use of the heat carried by the high-temperature flue gas, which is beneficial to improving energy efficiency.

[0049] Specifically, the energy collecting disk is a structure that can gather heat to prevent the heat from being lost too quickly, and needs to be used in conjunction with the burner 1000. The burner 1000 is a structure that allows gas to flow into it and out of it, so that the gas is ignited to form a flame. For example, the burner 1000 includes a burner head and an ejector pipe, which is connected to the burner head. The ejector pipe is used to cooperate with the gas supply mechanism to eject gas toward the burner head, and at the same time eject a certain amount of air to mix with the gas to form a mixed gas and transport it to the burner head. The mixed gas then flows out of the burner head and is ignited by the ignition needle.

[0050] Generally speaking, the gas supply mechanism includes a nozzle, which receives gas from pipeline natural gas or bottled liquefied gas. The nozzle corresponds to the air inlet of the ejector tube. The nozzle sprays the gas into the ejector tube, and at the same time drives the outside air into the ejector tube through the air inlet of the ejector tube, so that the gas and air are initially mixed in the ejector tube. The ejector tube ejects the mixed gas to the burner head. The burner head has a larger space than the ejector tube, which can make the gas and air further mixed evenly, which is conducive to the full combustion of the gas. A fire cover structure is generally provided on the burner head. The fire cover structure has a fire outlet hole, which is connected to the inside of the burner head. The mixed gas formed by the gas and air is ejected from the fire outlet hole and then ignited by the discharge of the nearby ignition needle to form a flame. It can be understood that the structure of the burner 1000 is not limited to the above example.

[0051] When the burner 1000 is burning, the high-temperature flue gas generated by the burner 1000 will carry heat and dissipate in all directions. In order to prevent the heat from being lost too quickly with the high-temperature flue gas, an energy gathering disk is provided. The energy gathering disk surrounds the burner 1000. In this way, the heat generated by the burner 1000 is gathered, thereby preventing the heat from being lost too quickly. However, as the burner 1000 continues to burn, the heat will still be lost with the flow of the high-temperature flue gas. Therefore, in order to make more effective use of heat and improve energy efficiency, in this embodiment, this is achieved by optimizing the structure of the energy gathering disk.

[0052] The first plate body 2000 of the energy-gathering plate is arranged around the burner 1000. The first plate body 2000 is an annular structure. In this embodiment, the annular shape can be a circular ring or a non-circular ring (such as a square ring). In this way, the first plate body 2000 can enclose an inner cavity 2100. After the burner 1000 and the first plate body 2000 are installed on the gas stove, the first plate body 2000 is in a state of surrounding the burner 1000. It is worth noting that the so-called surrounding means that the first plate body 2000 is in the circumferential direction of the burner 1000. When the burner 1000 is observed along the axial direction (such as the up and down direction), the burner 1000 is located in the inner cavity 2100. In this way, it is said that the first plate body 2000 surrounds the burner 1000. The so-called front, back, left, right, up and down directions are based on the gas stove installed in the kitchen. The side of the gas stove facing the user is the front, the side away from the user is the back, the side corresponding to the user's left hand is the left, the side corresponding to the user's right hand is the right, the side close to the ground is the bottom, and the side away from the ground is the top.

[0053] The first plate 2000 surrounds the burner 1000, and the first plate 2000 can be designed to be higher than the burner 1000, so that a certain space can be enclosed between the first plate 2000 and the burner 1000, and this space is convenient for gathering high-temperature flue gas, thus forming a high-temperature zone.

[0054] When heating the heated object 6000, the heated object 6000 is placed on the gas stove and located above the energy collecting plate. The heated object 6000 needs to be designed to be arranged alternately with the energy collecting plate, and the two are separated by a certain distance. In this way, as the burner 1000 continues to burn, although the first plate 2000 can gather heat, as the high-temperature flue gas is continuously generated, the high-temperature flue gas will flow upward and encounter the obstruction of the heated object 6000, and then change direction and radiate to the surroundings, and finally flow out to the outside through the space between the heated object 6000 and the energy collecting plate, and the heat is also lost.

[0055] In order to fully utilize the heat of the high-temperature flue gas flowing out of the inner cavity 2100, a second plate body 3000 is provided. The second plate body 3000 surrounds the first plate body 2000 and forms an outer cavity 3100 between the second plate body 3000 and the first plate body 2000. The design of the outer cavity 3100 enhances the heat preservation effect of the inner cavity 2100.

[0056] It is understandable that the first plate body 2000 is designed to be relatively close to the burner 1000, so the first plate body 2000 needs to be designed to be resistant to high temperatures, for example, it can be made of metal materials. However, it is difficult to insulate the first plate body 2000, so the first plate body 2000 itself also conducts heat and then dissipates heat to the outside. By designing the second plate body 3000 and forming an outer cavity 3100 between the second plate body 3000 and the first plate body 2000, the heat of the inner cavity 2100 can be prevented from being dissipated through the first plate body 2000 to a certain extent.

[0057] The outer cavity 3100 is designed to be open. During the flow of high-temperature flue gas, at least a portion (for example, a portion) of the high-temperature flue gas enters the outer cavity 3100, and the other portion of the high-temperature flue gas can directly flow out to the outside. This can increase the temperature of the outer cavity 3100, and then transfer the heat back to the heated object 6000.

[0058] Furthermore, the outer cavity 3100 is open toward the heated object 6000, so that the high-temperature flue gas generated by the burner 1000 flows upward and changes direction and flows divergently when encountering the obstruction of the heated object 6000. Since the outer cavity 3100 is open toward the heated object 6000, a part of the high-temperature flue gas can enter the outer cavity 3100.

[0059] Furthermore, since the inner cavity 2100 is a high temperature zone and the outer cavity 3100 is a low temperature zone, the open end of the outer cavity 3100 needs to be set on the outside of the inner cavity 2100, so that the heat carried by the high-temperature flue gas first flows to the open end of the outer cavity 3100 and then enters the outer cavity 3100 after sufficient heat exchange with the heated object 6000 in the inner cavity 2100, and continues to realize heat exchange with the heated object 6000 in the outer cavity 3100, thereby making full use of the heat carried by the high-temperature flue gas and effectively improving energy efficiency.

[0060] In order to make the heat entering the outer cavity 3100 and the heated object 6000 exchange heat more fully, the first plate body 2000 is designed to be gradually expanded upward, that is, the first plate body 2000 is gradually expanded from bottom to top, forming a trumpet-like structure that is open upward. In this way, the first plate body 2000 is provided with an outer concave cavity 2220 on one side facing the outer cavity 3100, and the outer concave cavity 2220 is concave facing away from the outer cavity 3100, and at least two outer concave cavities 2220 are provided along the gradually expanding direction of the first plate body 2000.

[0061] It can be understood that the so-called outer concave cavity 2220 , that is, a certain position on the side of the first plate body 2000 facing the outer cavity 3100 is concave relative to the surroundings of the position, thus constituting the outer concave cavity 2220 .

[0062] When the heated object 6000 is heated, heat is transferred to the outer cavity 3100 through the first plate 2000, so that the gas in the outer cavity 3100 is active and flows. At the same time, the high-temperature flue gas generated by the combustion of the burner 1000 flows upward. The high-temperature flue gas encounters the obstruction of the heated object 6000, and then changes direction and flows out from between the heated object 6000 and the first plate 2000. A part of the high-temperature flue gas enters the outer cavity 3100 and flows. The high-temperature flue gas flows along the first plate 2000 toward one side of the outer cavity 3100. Due to the presence of at least two outer concave cavities 2220, vortices are generated when the high-temperature flue gas flows through the outer concave cavities 2220. The generation of vortices can reduce the speed of the high-temperature flue gas, extend the flow path of the high-temperature flue gas, and make the high-temperature flue gas flow fully, so that the heat exchange between the high-temperature flue gas and the heated object 6000 can be improved, thereby further avoiding excessive heat loss.

[0063] It can be understood that there can be two, three, four or more outer concave cavities 2220. As mentioned above, the high-temperature flue gas will flow along the side of the first disk body 2000 toward the outer cavity 3100. When multiple (two or more) outer concave cavities 2220 are arranged along the gradually expanding direction of the first disk body 2000, it means that the multiple outer concave cavities 2220 are arranged from bottom to top, and the high-temperature flue gas will flow through each outer concave cavity 2220 in turn. Even if one of the outer concave cavities 2220 does not form a vortex for the high-temperature flue gas, the remaining outer concave cavities 2220 can form a vortex for the flue gas, thereby increasing the residence time of the high-temperature flue gas in the outer cavity 3100.

[0064] Combination Figure 6 and Fig.10 As shown, in some embodiments of the present application, along the gradually expanding direction of the first disk body 2000, at least two inner concave cavities 2210 are provided on one side of the first disk body 2000 facing the inner cavity 2100, so that the residence time of the high-temperature flue gas in the inner cavity 2100 can be prolonged.

[0065] Specifically, a concave cavity 2210 is provided on one side of the first plate body 2000 facing the inner cavity 2100, the concave cavity 2210 is concavely arranged away from the inner cavity 2100, and at least two concave cavities 2210 are arranged along the gradually expanding direction of the first plate body 2000. It can be understood that the so-called concave cavity 2210, i.e., a certain position on the side of the first plate body 2000 facing the inner cavity 2100 is concavely arranged relative to the surrounding of the position, thus constituting the concave cavity 2210.

[0066] When the heated object 6000 is heated, the high-temperature flue gas generated by the burner 1000 flows upward and encounters the obstruction of the heated object 6000, and then changes direction and flows around. In this process, since the flue gas flows around, the flue gas flows along the first plate 2000 toward the side of the inner cavity 2100, and the high-temperature flue gas flows through each concave cavity 2210 in turn. It is also the function of the concave cavity 2210 that causes the high-temperature flue gas to generate an eddy current on the side of the first plate 2000 toward the inner cavity 2100. The formation of the eddy current allows the flue gas to stay in the inner cavity 2100 longer, which can further avoid excessive heat loss.

[0067] The number of the inner concave cavities 2210 may be one, two, three, four or more. As mentioned above, the high-temperature flue gas will flow along the first disk body 2000 toward one side of the inner cavity 2100. When multiple (two or more) inner concave cavities 2210 are arranged along the gradually expanding direction of the first disk body 2000, it means that the multiple inner concave cavities 2210 are arranged from bottom to top, and the high-temperature flue gas will flow through each inner concave cavity 2210 in turn. Even if the lowest inner concave cavity 2210 does not form a vortex for the high-temperature flue gas, the upper inner concave cavity 2210 can form a vortex for the flue gas, thereby increasing the residence time of the high-temperature flue gas in the inner cavity 2100.

[0068] Combination Figure 2 and Figure 6 As shown, in some embodiments of the present application, the inner concave cavity 2210 is designed to protrude toward the outer cavity 3100, while the outer concave cavity 2220 is designed to protrude toward the inner cavity 2100, and along the gradually expanding direction of the first disk body 2000, the inner concave cavity 2210 and the outer concave cavity 2220 are designed to be alternately arranged.

[0069] Specifically, when the inner concave cavity 2210 is concavely arranged away from the inner cavity 2100 and convexly arranged toward the outer cavity 3100, and the outer concave cavity 2220 is concavely arranged away from the outer cavity 3100 and convexly arranged toward the inner cavity 2100, the inner concave cavity 2210 and the outer concave cavity 2220 are alternately arranged in sequence along the gradually expanding direction of the first disk body 2000, so that the inner concave cavity 2210 and the outer concave cavity 2220 form a continuous undulating structure, similar to a step structure, so that an outer concave cavity 2220 can be formed between two adjacent inner concave cavities 2210, and an inner concave cavity 2210 can be formed between two adjacent outer concave cavities 2220, so that the inner concave cavity 2210 and the outer concave cavity 2220 can be designed to be closer, and when the high-temperature flue gas flows along the side of the first disk body 2000 toward the inner cavity 2100 and the side toward the outer cavity 3100, it is easier to form a continuous vortex, thereby enhancing the retention effect of the high-temperature flue gas.

[0070] In addition, by convexly arranging the outer concave cavity 2220 toward the inner cavity 2100 and convexly arranging the inner concave cavity 2210 toward the outer cavity 3100, the manufacturing difficulty of the inner concave cavity 2210 and the outer concave cavity 2220 can be reduced, and the cost of the first plate body 2000 can also be reduced. For example, the first plate body 2000 is made of a metal plate, and the metal plate is clamped by two molds. Since the metal plate has a certain ductility, the metal plate can form the inner concave cavity 2210 and the outer concave cavity 2220, thereby improving production efficiency.

[0071] Combination Figure 2 and Figure 6 As shown, in some embodiments of the present application, the top 2400 of the first plate 2000 is spaced apart from the heated object 6000, and the side of the top 2400 of the first plate 2000 facing the heated object 6000 is defined as a guide side 2410, and the guide side 2410 is designed to be parallel to the heated object 6000.

[0072] Specifically, by setting the guide side 2410, the guide side 2410 and the heated object 6000 are designed to be parallel to each other, so that when the high-temperature flue gas flows between the guide side 2410 and the heated object 6000, a laminar flow will be formed. The formation of the laminar flow accelerates the flow of the high-temperature flue gas, thereby strengthening the flushing of the heated object 6000, which is conducive to improving the convective heat transfer coefficient, achieving more efficient heat transfer, and further improving the heat exchange effect. It can be understood that the so-called parallelism means that a flow channel is formed between the guide side 2410 and the corresponding part of the heated object 6000, and the flow area of ​​the flow channel is relatively constant in the direction of the high-temperature flue gas flow, thereby forming a laminar flow.

[0073] For example, the top 2400 of the first plate 2000 forms a guide side 2410, and the guide side 2410 is horizontally arranged. The guide side 2410 corresponds to the bottom of the heated object 6000, and is alternately arranged with the bottom of the heated object 6000. When the heated object 6000 is a cooker, the guide side 2410 is arranged corresponding to the bottom of the cooker, and a flow channel is formed between the guide side 2410 and the bottom of the pot. When the smoke is discharged through the guide side 2410 and the bottom of the pot, laminar flow can be formed, thereby strengthening the scouring of the bottom of the pot, thereby improving the convective heat transfer coefficient.

[0074] In order to ensure that effective laminar flow is formed between the flow guide side 2410 and the heated object 6000, Figure 2As shown, in some embodiments of the present application, the energy concentrating disk also includes a support leg 5000, and the heated object 6000 is used to be placed on the support leg 5000, so as to be spaced apart from the guide side 2410, and the distance between the guide side 2410 and the highest point of the support leg 5000 is H, satisfying 2mm≤H≤10mm, especially when H satisfies 4mm≤H≤6mm, it has a better laminar flow effect and meets the use of different heated objects 6000.

[0075] It is understandable that the support leg 5000 can be set on the first plate body 2000 or on the second plate body 3000. Of course, the support leg 5000 can be fixed in both the first plate body 2000 and the second plate body 3000 at the same time. It can be set according to actual conditions.

[0076] Combination Figure 7 , Figure 8 and Fig. 9 As shown, in some embodiments of the present application, the top 2400 of the first plate 2000 is spaced apart from the heated object 6000, and the side of the top 2400 of the first plate 2000 facing the heated object 6000 is defined as a guide side 2410, and the guide side 2410 is designed as a non-planar structure. In this embodiment, the guide side 2410 and the heated object 6000 are arranged alternately, and the high-temperature flue gas generated by the burner 1000 can flow out from between the guide side 2410 and the heated object 6000. By designing the guide side 2410 as a non-planar structure, the high-temperature flue gas can encounter greater resistance along the way when flowing through the guide side 2410, thereby reducing the speed of the high-temperature flue gas flowing between the guide side 2410 and the heated object 6000, that is, the high-temperature flue gas flows slower (relatively speaking, relative to the guide side 2410 being a plane). When the high-temperature flue gas flows slower, it can have a longer contact time with the heated object 6000, thereby extending the contact time between the high-temperature flue gas and the heated object 6000, improving the heat exchange effect between the high-temperature flue gas and the heated object 6000, and further improving energy efficiency.

[0077] Non-planar structures have various forms, combining Figure 7 and Figure 8 As shown, in some embodiments of the present application, the guide side 2410 is designed as a concave-convex structure, and the so-called concave-convex structure is a structure having a concave portion (hereinafter referred to as the first concave portion 2412) and a convex portion (hereinafter referred to as the first convex portion 2411), and the concave-convex structure is formed by the cooperation of the concave portion (first concave portion 2412) and the convex portion (first convex portion 2411). In the process of high-temperature flue gas flowing through the guide side 2410, the high-temperature flue gas will be subject to the resistance applied by the concave portion (first concave portion 2412) and the resistance applied by the convex portion (first convex portion 2411). By setting the concave-convex structure, the flow speed of the high-temperature flue gas is further slowed down.

[0078] Continue to combine Figure 7 and Figure 8 As shown, in some embodiments of the present application, the guide side 2410 has a first recess 2412 and a first protrusion 2411 , and the first recess 2412 and the first protrusion 2411 are arranged along the radial direction of the first disk body 2000 .

[0079] Specifically, the first recess 2412 and the first convex portion 2411 are arranged along the radial direction of the first disk body 2000. The first recess 2412 may be closer to the center of the first disk body 2000 relative to the first convex portion 2411, or the first convex portion 2411 may be closer to the center of the first disk body 2000 relative to the first recess 2412. The high-temperature flue gas flows outward from the inner cavity 2100 enclosed by the first disk body 2000.

[0080] That is to say, the first recess 2412 and the first protrusion 2411 constitute a concave-convex structure along the radial direction of the first disk 2000. When the high-temperature flue gas flows through the guide side 2410, it will be subjected to resistance by the first recess 2412 and the first protrusion 2411. In this way, when the high-temperature flue gas flows through the first recess 2412 and the first protrusion 2411, it will produce ups and downs and form small vortices. The formation of vortices further increases the flow resistance of the high-temperature flue gas, prolongs the residence time of the high-temperature flue gas, and can make the high-temperature flue gas flow fully, thereby further improving the heat exchange effect between the high-temperature flue gas and the heated object 6000.

[0081] Continue to combine Figure 7 and Figure 8 As shown, in some embodiments of the present application, the first recess 2412 and the first protrusion 2411 are designed to be alternately arranged along the radial direction of the first disk 2000, so that the first recess 2412 and the first protrusion 2411 form a wave shape, further improving the flow resistance to the high-temperature flue gas, thereby further enhancing the heat exchange effect between the high-temperature flue gas and the heated object 6000.

[0082] Specifically, if the first concave portions 2412 and the first convex portions 2411 are to be arranged alternately, at least two first concave portions 2412 need to be provided, and / or at least two first convex portions 2411 need to be provided.

[0083] In this example, two first convex portions 2411 and one first concave portion 2412 are provided, wherein one first convex portion 2411 is closer to the center of the first disk body 2000 than the other first convex portion 2411 and the first concave portion 2412, and the first concave portion 2412 is located between the two first convex portions 2411. By alternately providing the first convex portions 2411 and the first concave portions 2412, the guide side 2410 forms a continuous undulating structure (wave-like) in the radial direction of the first disk body 2000, which better hinders the high-temperature flue gas flowing through the guide side 2410, so that the high-temperature flue gas flows more slowly through the guide side 2410.

[0084] Continue to combine Figure 7 and Figure 8 As shown, in some embodiments of the present application, the first recess 2412 is designed to be adjacent to the first protrusion 2411, so that more first recesses 2412 and first protrusions 2411 can be provided with the same size.

[0085] It is understandable that the size of the guide side 2410 needs to be adapted to the heated object 6000. It is obvious that the size of the guide side 2410 is much larger than the heated object 6000. For example, after the heated object 6000 is placed on the gas stove, the guide side 2410 will be blocked by the heated object 6000 when viewed from top to bottom, or the guide side 2410 slightly exceeds the heated object 6000. If the size of the guide side 2410 is designed to be too large, the first plate 2000 will cover a large area of ​​the panel 7000 of the gas stove, reducing the aesthetics. For this reason, in this embodiment, the first concave portion 2412 and the first convex portion 2411 are designed to be adjacent, so that the space of the guide side 2410 can be fully utilized, and more first concave portions 2412 and first convex portions 2411 can be designed under limited size. For example, the guide side 2410 has two first protrusions 2411 , and the two first protrusions 2411 surround a first recess 2412 , so that the first recess 2412 is adjacent to the two first protrusions 2411 , respectively, and the limited space of the guide side 2410 is fully utilized.

[0086] Combination Fig. 9As shown, in some embodiments of the present application, the flow guiding side 2410 has a flow guiding rib 2413, and the flow guiding rib 2413 includes a plurality of flow guiding ribs 2413, and the plurality of flow guiding ribs 2413 are alternately arranged along the circumference of the first disk body 2000, so that a flow guiding channel 2414 is formed between adjacent flow guiding ribs 2413, and the extension direction of the flow guiding channel 2414 is designed to deviate from the radial direction of the first disk body 2000, that is, it is skewed relative to the radial direction of the first disk body 2000. By providing the flow guiding rib 2413 and the skewed flow guiding channel 2414 formed by the adjacent flow guiding ribs 2413, the flow path of the high-temperature flue gas can be extended, so that the high-temperature flue gas and the heated object 6000 can achieve a longer contact heat exchange, which can also improve the heat exchange effect and energy efficiency.

[0087] Specifically, when the high-temperature flue gas floats upward and encounters the obstruction of the heated object 6000, the high-temperature flue gas will flow in all directions. This flow in all directions is roughly along the radial direction of the first disk body 2000. In this embodiment, by providing the guide ribs 2413, the guide channels 2414 formed by the adjacent guide ribs 2413 are inclined relative to the radial direction of the first disk body 2000. In this way, when the high-temperature flue gas flows to the guide channel 2414, it will also follow the extension direction of the guide channel 2414 relative to the first disk body 2000. The high-temperature flue gas flows in a skewed radial direction. Thus, when the high-temperature flue gas flows to the guide channel 2414, it can no longer flow in the radial direction of the first disk 2000, but changes direction under the obstruction of the channel wall (guide rib 2413) of the guide channel 2414, so as to continue to flow along the extension direction of the guide channel 2414. This is equivalent to extending the flow path of the high-temperature flue gas. The longer flow path of the high-temperature flue gas means that the high-temperature flue gas can achieve more sufficient contact with the heated object 6000, which is conducive to improving the heat exchange effect. It can be understood that the interval arrangement of the guide ribs 2413 is also equivalent to forming a concave-convex structure on the guide side 2410, which, in conjunction with the skewed arrangement of the guide channel 2414, can greatly improve the heat exchange effect between the high-temperature flue gas and the heated object 6000.

[0088] Continue to combine Fig. 9As shown, in some embodiments of the present application, the guide channel 2414 is curved, so that the flow path of the high-temperature flue gas flowing through the guide side 2410 can be further extended. Specifically, since the guide channel 2414 is surrounded by the guide ribs 2413, the guide channel 2414 is curved, which means that the two adjacent guide ribs 2413 are also curved. Multiple guide channels 2414 can be curved in the same direction or in different directions. Compared with the latter, the former can save more space and a larger number of guide channels 2414 can be arranged in a limited space. It can be understood that between two points, the curve has a longer length than the straight line. The guide channel 2414 is designed to be curved, so that the flow path of the high-temperature flue gas can be further extended. The flue gas flows through the guide side 2410 in a swirl, and then the high-temperature flue gas and the heated object 6000 are further contacted and heat exchanged.

[0089] Continue to combine Fig. 9 As shown, in some embodiments of the present application, the flow cross-section of the guide channel 2414 is designed to gradually increase. It can be understood that the gradual increase here refers to the gradual increase of the flow cross-section of the guide channel 2414 in the direction from the inlet of the guide channel 2414 to the outlet of the guide channel 2414. In this way, the flow velocity of the high-temperature flue gas can be further reduced, thereby improving the heat exchange effect between the high-temperature flue gas and the heated object 6000.

[0090] Combination Figure 6 and Figure 8 As shown, in some embodiments of the present application, the guide side 2410 extends a preset distance in the horizontal direction, so that the space formed between the guide side 2410 and the heated object 6000 has a certain width in the horizontal direction, so that when the flue gas flows through the guide side 2410 and the heated object 6000, it can flush and / or contact the heated object 6000 over a certain width, further improving the heat exchange effect.

[0091] Combination Figure 4As shown, in some embodiments of the present application, along the radial direction of the first disk body 2000, the size of the open end of the outer cavity 3100 (the open end is the opening of the outer cavity 3100) is designed to be 10 mm to 60 mm. It can be understood that the size of the open end of the outer cavity 3100 along the radial direction of the first disk body 2000 is L, which satisfies 10mm≤L≤60mm, for example, L is 60mm, 50mm, 40mm, 35mm, 30mm, 23mm, 20mm, 10mm, so as to ensure a certain gap for high-temperature flue gas to enter the outer cavity 3100, but L cannot be too small, otherwise it will affect the high-temperature flue gas entering the outer cavity 3100 through the open end of the outer cavity 3100, and affect the high-temperature flue gas in the outer cavity 3100 flowing out through the open end of the outer cavity 3100. In order to take into account the entry and exit of high-temperature flue gas and the heat exchange between the high-temperature flue gas in the outer cavity 3100 and the heated object 6000, after a large number of experiments, it is better to design L to 20mm≤L≤40mm.

[0092] Combination Figure 2 and Figure 3 As shown, in some embodiments of the present application, the second plate 3000 is designed to be higher than the first plate 2000 , so that the high-temperature flue gas flowing out of the inner cavity 2100 can more easily enter the outer cavity 3100 and form a vortex in the outer cavity 3100 .

[0093] Specifically, when the high-temperature flue gas flows out from between the heated object 6000 and the first plate 2000, since the second plate 3000 is designed to be higher than the first plate 2000, a part of the high-temperature flue gas can directly collide with the second plate 3000, and since the outer cavity 3100 is open toward the heated object 6000 and the other part of the flue gas will flow out from the gap between the second plate 3000 and the heated object 6000, then the above-mentioned part of the airflow will flow downward along the side of the second plate 3000 facing the outer cavity 3100 under the action (pressure) of the above-mentioned other part of the airflow, and then flow to the side of the first plate 2000 facing the outer cavity 3100, and then change to flow upward along the side of the first plate 2000 facing the outer cavity 3100, forming a vortex under the action of the outer concave cavity 2220.

[0094] Combination Figure 5As shown, in some embodiments of the present application, a first cavity 2300 is formed between the outer side and the inner side of the first plate body 2000, so that the first plate body 2000 constitutes a hollow structure. It can be understood that the inner side of the first plate body 2000 is the side facing the inner cavity 2100, and the outer side of the first plate body 2000 is the side facing the outer cavity 3100. For example, the first plate body 2000 is a double-layer structure to form the first cavity 2300. The formation of the first cavity 2300 is conducive to enhancing the heat preservation effect of the first plate body 2000, and can avoid the heat loss of the inner cavity 2100 to a certain extent. When the first plate body 2000 is provided with an outer concave cavity 2220, the outer concave cavity 2220 can be formed on the outermost structure of the first plate body 2000. It can be understood that the first plate body 2000 can be a double-layer structure to form the first cavity 2300, or a multi-layer structure (three layers or more) to form at least two first cavities 2300.

[0095] The same is true for the second plate body 3000. A second cavity 3200 is formed between the outer side and the inner side of the second plate body 3000, so that the second plate body 3000 has a hollow structure. It can be understood that the inner side of the second plate body 3000 is the side facing the outer cavity 3100, and the outer side of the second plate body 3000 is the side facing away from the outer cavity 3100. For example, the second plate body 3000 has a double-layer structure to form the second cavity 3200. The formation of the second cavity 3200 is conducive to enhancing the thermal insulation effect of the second plate body 3000, and can prevent the heat of the outer cavity 3100 from being lost through conduction through the second plate body 300 to a certain extent.

[0096] The present application also discloses a gas stove, Figure 1 As shown, the gas stove includes the energy gathering plate of the above embodiment. It can be understood that the energy gathering plate of the gas stove of this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.
