[0029] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In the related art, most stoves are open combustion, and the smoke generated by the combustion contains a large amount of heat. The smoke can easily escape into the surrounding environment through convection and radiation, thereby reducing the heat transfer efficiency and causing energy waste.

[0031] For the above situation, please see Figure 1 On the one hand, the present application proposes a burner 1, including a main body 10 and a bracket 20. The main body 10 has a fire outlet 11. A mixed gas of fuel gas and external air (this part of air is called primary air) is introduced into the main body 10, and then the mixed gas is ejected from the fire outlet 11 of the main body 10 and ignited by an ignition device to form a flame (the air required for combustion is called secondary air). These flames are used to heat the pots above.

[0032] The bracket 20 is arranged on the top of the main body 10, and the fire outlet 11 is located on the inner side of the bracket 20, that is, the flame burns inside the bracket 20, wherein the bracket 20 and the main body 10 can be fixedly connected, such as welding, clamping, screwing, etc.; or, the bracket 20 and the main body 10 can be placed in an unfixed manner, for example, the bracket 20 is placed on the main body 10 in a freely detachable form. The preparation material of the bracket 20 can be steel, aluminum, copper and other metal plates, which can not only improve the strength of the bracket 20, but also reduce the adverse effects of the flame on the bracket 20, and the bracket 20 can be prepared by sheet metal or stamping processes, and the embodiments of the present application do not impose specific restrictions on this.

[0033] like Figure 1 As shown, the bracket 20 includes an upper part 21 and a lower part 22 connected to each other, the lower part 22 is located between the main body 10 and the upper part 21, and the lower part 22 has a gas flow channel 221, and the gas flow channel 221 is used for external gas to flow into the inner side of the bracket 20 to reach the fire outlet 11.

[0034] Specifically, the external secondary air can flow into the inner side of the bracket 20 from the gas flow channel 221 of the lower part 22 of the bracket 20 to supplement the air for the gas at the fire outlet 11 and to provide the gas for combustion inside the bracket 20. The smoke generated by the combustion is inside the bracket 20. The smoke needs to bypass the upper part 21 of the bracket 20 before it can diffuse out. In other words, the upper part 21 of the bracket 20 hinders the diffusion of the smoke, slowing down the diffusion of the smoke, so that the smoke can more fully exchange heat with the pot. At the same time, since the burning flame is located on the inner side of the bracket, the temperature of the bracket itself is relatively high. When the external secondary air enters the inner side of the bracket through the gas flow channel, the bracket will first preheat the secondary air to a certain extent, and then the preheated secondary air will enter the inner side of the bracket for gas combustion. Among them, the lower part 22 of the bracket 20 can be provided with a through hole connecting the inner side and the outer side of the bracket 20, and the through hole forms a gas flow channel 221 for gas to enter and exit.

[0035] It should be noted that when the gas is burned, smoke (incompletely burned gas and hot air) is generated, and the smoke contains a large amount of heat. In the embodiment of the present application, a bracket 20 is arranged above the main body 10. Because the gas in the burner 1 burns above the fire outlet 11, the temperature inside the bracket 20 is higher, and the hot air rises upward from the inside of the bracket 20 until the hot air diffuses from the top of the bracket 20 to the outside of the bracket 20. That is to say, the upper part 21 of the bracket 20 can hinder the diffusion of the smoke to a certain extent, so that the smoke gathers inside the bracket 20 and rolls toward the top and outside of the bracket 20, and the diffusion of the smoke slows down, thereby extending the residence time of the smoke between the cookware and the burner 1, thereby allowing the smoke to more fully exchange heat with the cookware and improve the heat transfer efficiency between the smoke and the cookware; at the same time, the gas flow channel 221 located at the lower part 22 of the bracket 20 can also provide external secondary air to enter the inside of the bracket 20, so that the gas can be more fully burned, thereby improving the combustion efficiency of the burner 1 and reducing the generation of smoke.

[0036] In some embodiments, a circle of guide surface with a slope may be provided outside the connection between the upper part 21 and the lower part 22. For example, the guide surface is provided to be inclined downward from the connection between the upper part 21 and the lower part 22. When the gas stove is in use, the soup inside the pot may overflow, and the outflowing liquid will slide down along the edge of the pot, and then the overflowing liquid may slide down along the guide surface. The provision of the guide surface can reduce the liquid from entering the inside of the bracket 20, thereby reducing the influence of the external liquid on the fire outlet 11 of the burner 1.

[0037] Please continue to see Figure 1 In some embodiments of the present application, the bracket 20 is annular, that is, the bracket 20 is arranged in a circle on the top outer edge of the main body 10, and the annular bracket 20 and the main body 10 together form a gas mixing chamber 12, and the fire outlet 11 is located in the gas mixing chamber 12.

[0038] Among them, the gas burns in the mixing chamber 12, and the generated smoke will diffuse outward from the mixing chamber 12. The annular lower part 22 can increase the contact area between the bracket 20 and the main body 10, so that the installation of the bracket 20 is more stable. The annular upper part 21 can also enhance the blocking effect on the smoke in the mixing chamber 12, further delay the speed of the smoke diffusion from the mixing chamber 12 to the outside, and extend the residence time of the smoke in the mixing chamber 12, thereby allowing the smoke in the mixing chamber 12 to more fully exchange heat with the cookware, thereby improving the heat transfer efficiency between the smoke and the cookware.

[0039] In some other embodiments, the bracket 20 may also be formed by a plurality of arc-shaped structures arranged in a vertical interval; or, the bracket 20 may be formed by a plurality of arc-shaped structures arranged in a vertical interval and spliced ​​together.

[0040] Please continue to see Figure 1 The upper portion 21 of the bracket 20 extends vertically, or the upper portion 21 of the bracket 20 extends obliquely upward, both of which can increase the height of the upper portion 21 in the vertical direction, so that the time required for the smoke to tumble from the top of the upper portion 21 to the outside of the bracket 20 becomes longer, that is, the speed at which the smoke diffuses out of the mixing chamber 12 becomes slower, thereby allowing the smoke to more fully exchange heat with the cookware in the mixing chamber 12, thereby further improving the heat transfer efficiency between the smoke and the cookware.

[0041] See also Figure 1-Figure 2 In some embodiments of the present application, the lower portion 22 includes a connecting plate 222 and a baffle 223. The connecting plate 222 is connected to the upper portion 21. The baffle 223 is connected to the side of the connecting plate 222 that is away from the upper portion 21. A plurality of baffles 223 are provided, and the plurality of baffles 223 are arranged vertically at intervals on the connecting plate 222, and a gas flow channel 221 is formed between two adjacent baffles 223.

[0042] Specifically, when the bracket 20 is annular, a plurality of baffles 223 are arranged at intervals around the axial direction of the bracket 20 on the connecting plate 222. The side of the baffle 223 away from the connecting plate 222 contacts the main body 10, and the gas flow channel 221 is formed by the connecting plate 222, the baffle 223 and the main body 10. The plurality of baffles 223 can form a plurality of gas flow channels 221, so as to quickly replenish the secondary air for the fire outlet 11 inside the bracket 20, so that the gas can be more fully burned, thereby improving the combustion efficiency of the burner 1.

[0043] Alternatively, a side of the baffle 223 away from the connecting plate 222 is also provided with an abutment plate, which contacts and connects with the outer edge of the main body 10, and the gas flow channel 221 can also be formed by the connecting plate 222, the baffle 223 and the abutment plate; or, the abutment plate, the baffle 223 and the connecting plate 222 can be integrally cast, and the gas flow channel 221 can be reserved in advance during casting. Among them, the gas flow channel 221 can be a square hole channel or a cylindrical hole channel, etc., and the length of the gas flow channel 221 is the length of the baffle 223 along the inner side of the bracket 20 to the outer side of the bracket 20. The length of the gas flow channel 221 can affect the speed of gas replenishment, which can be selected according to actual conditions, and this embodiment does not make specific limitations.

[0044] See also Figure 1In some embodiments of the present application, the upper portion 21 includes an annular plate body, which may extend vertically or obliquely upward. The annular plate body is located at the outer edge of the connecting plate 222, and the side wall of the annular plate body facing the inner side of the bracket 20 and the connecting plate 222 enclose the first slot body 211, that is, the first slot body 211 is located in the gas mixing chamber 12. When the smoke generated by combustion gathers in the gas mixing chamber 12, the smoke with a higher temperature rises upward on the inner side of the bracket 20, and the smoke is hindered from diffusing by the upper portion 21 at the position of the first slot body 211, so that the smoke swirls at the position of the first slot body 211, prolonging the residence time of the smoke in the gas mixing chamber 12, thereby allowing the smoke to more fully exchange heat with the cookware, thereby improving the heat transfer efficiency between the smoke and the cookware.

[0045] See also Figure 2-Figure 3 In some embodiments of the present application, a plurality of baffles 223 are arranged on the connecting plate 222 and extend along a first direction, where the first direction is a direction from the inside to the outside of the bracket 20 .

[0046] Specifically, when the bracket 20 is annular, multiple baffles 223 are arranged on the connecting plate 222 and extend radially along the bracket 20, that is, the first direction is the radial direction of the bracket 20, thereby making the length of the gas flow channel 221 the shortest, that is, the external secondary air can pass through the gas flow channel 221 as quickly as possible and reach the fire hole 11, which is beneficial to improving the combustion efficiency of the burner 1 and reducing the generation of smoke.

[0047] Or, if Figure 4 As shown, multiple baffles 223 can also be arranged at an angle on the connecting plate 222, that is, the gas flow channel 221 formed by the baffles 223 is also arranged at an angle. When the wind in the external environment is strong, the inclined baffles 223 will block a part of the secondary air that blows directly toward the flame, and the secondary air will reach the fire outlet 11 along the inclined flow channel, thereby reducing the influence of the secondary air on the burning flame at the fire outlet 11, and reducing the swaying, instability or extinction of the burning flame.

[0048] Alternatively, see Figure 5 In some embodiments of the present application, the baffle 223 includes a first plate body 2231 and a second plate body 2232 that are connected to each other. The first plate body 2231 and the second plate body 2232 are arranged at an angle, that is, the first plate body 2231 and the second plate body 2232 are arranged in a V shape, and the connecting portion between the first plate body 2231 and the second plate body 2232 is arranged close to the outer edge of the upper part 21.

[0049] Specifically, taking the case where the baffle 223 includes a first baffle and a second baffle, and the first baffle and the second baffle are arranged adjacent to each other, a gas flow channel 221 is formed between the first baffle and the second baffle, that is, a gas flow channel 221 is formed between the first plate body 2231 in the first baffle and the second plate body 2232 in the second baffle. At this time, the first plate body 2231 (in the first baffle) and the second plate body 2232 (in the second baffle) form an air inlet for secondary air near the outer edge of the upper portion 21. The first plate 2231 and the second plate 2232 form a secondary air outlet near the inner edge of the upper portion 21. Negative pressure is generated in the mixing chamber 12 during combustion to draw external secondary air from the air inlet. Since the baffles 223 are all V-shaped, the orthographic projection area of ​​the air inlet is larger than the orthographic projection area of ​​the air outlet, so that the flow rate of the gas after entering the gas flow channel 221 increases, so that the gas in the mixing chamber 12 can be burned more fully, thereby improving the combustion efficiency of the burner 1.

[0050] See also Figure 1-Figure 5 In some embodiments of the present application, a fixing part 224 is provided on the side of the connecting plate 222 facing away from the upper part 21, and the fixing part 224 passes through the gas flow channel 221 and is connected to the outer edge top surface of the main body 10. For example, the fixing part 224 is a connecting column, which passes through the gas flow channel 221 and connects the bracket 20 and the main body 10. The connecting column and the main body 10 can be fixed by screwing, clamping or plugging, which is not specifically limited here.

[0051] See also Figure 6 In some embodiments of the present application, the main body 10 includes an outer combustion portion 13, the bracket 20 is arranged at the outer edge of the outer combustion portion 13, the fire hole 11 is arranged on the top surface of the outer combustion portion 13, and the fire hole 11 is arranged corresponding to the gas flow channel 221, so that the secondary air entering from the gas flow channel 221 can reach the fire hole 11 as quickly as possible to supplement air for gas combustion, which is beneficial to the full combustion of the gas.

[0052] Furthermore, the fire hole 11 ejects gas vertically and burns, and the top surface of the outer combustion portion 13 extends downward from the outer edge to the inner edge, so that the gas ejected from the fire hole 11 is inclined toward the gas mixing chamber 12, reducing the heat diffused from the side of the burner 1, thereby better concentrating the heat at the bottom of the cookware.

[0053] It should be noted that if Figure 6-Figure 7As shown, the outer combustion part 13 includes an outer ring base 131 and an outer ring fire cover arranged on the outer ring base 131, the outer ring fire cover is provided with a fire hole 11, the outer ring base 131 has a first cavity, the first cavity is connected with the fire hole 11 on the outer ring fire cover, the mixed gas of fuel gas and primary air is introduced into the first cavity of the outer ring base 131 from the outside, and then ejected from the fire hole 11 of the outer ring fire cover to form a combustion flame.

[0054] See also Figure 6 In some embodiments of the present application, a plurality of fire holes 11 are provided, and the plurality of fire holes 11 are arranged at intervals around the outer combustion part 13 in a vertical direction. The gas introduced into the main body 10 is quantitative, and a plurality of fire holes 11 are provided, so that the gas can be more evenly distributed to each fire hole 11. If each fire hole 11 is provided with less gas, the gas in each fire hole 11 can be burned more fully, thereby improving the combustion efficiency of the burner 1. At the same time, a plurality of gas flow channels 221 are provided, and the plurality of gas flow channels 221 are arranged at intervals around the outer edge of the outer combustion part 13 in a vertical direction. A plurality of gas flow channels 221 are provided, so that more external secondary air can be supplied to enter the gas mixing chamber 12, so that the gas in the gas mixing chamber 12 can be burned more fully, thereby improving the combustion efficiency of the burner 1.

[0055] See also Figure 6-Figure 7 In some embodiments of the present application, the main body 10 further includes an inner combustion part 14 connected to the outer combustion part 13, the inner combustion part 14 is arranged inside the outer combustion part 13, and there is an air supply channel 15 between the inner combustion part 14 and the outer combustion part 13, wherein the air supply channel 15 is connected with the gas mixing chamber 12, so that the external air enters the gas mixing chamber 12 of the main body 10 from the air supply channel 15, so as to provide the gas for combustion in the gas mixing chamber 12. A plurality of fire outlet holes 11 are provided, and the plurality of fire outlet holes 11 are respectively provided on the side surface and the top surface of the inner combustion part 14, so that the external gas entering from the air supply channel 15 can reach the fire outlet holes 11 on the side surface of the inner combustion part 14 at the first time, and the external gas entering from the gas flow channel 221 can quickly reach the fire outlet holes 11 on the fixed surface of the inner combustion part 14, so as to provide the gas for full combustion.

[0056] It should be noted that if Figure 6-Figure 7 As shown, the inner combustion part 14 includes an inner ring base 141 and an inner ring fire cover arranged on the inner ring base 141, and the inner ring fire cover is also provided with a fire hole 11.

The mixed gas of fuel gas and primary air is introduced into the second cavity of the inner ring base 141 from the outside, and then ejected from the fire hole 11 of the inner ring fire cover to form a combustion flame.

[0057] It should also be noted that a plurality of connecting spokes 16 are arranged between the outer ring base 131 and the inner ring base 141, and the plurality of connecting spokes 16 are arranged at intervals around the circumference of the inner combustion part 14, and a gas supply channel 15 is formed between two adjacent connecting spokes 16. The connecting spokes 16 have spoke cavities, and the spoke cavities are connected to the first cavity and the second cavity, and the mixed gas of the fuel gas and the primary air can be directly introduced into one of the first cavity and the second cavity, and then the mixed gas diffuses to reach the other cavity.
