Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a high-efficiency burner. Background Technology

[0002] A burner is a type of cooking appliance widely used in kitchens. These appliances typically consist of two main parts: the combustion chamber and the burner. The burner, as the core functional component, mainly includes the burner head cover, air inlet pipe, and fuel inlet pipe. Fuel is introduced through the fuel inlet pipe, while air is introduced through the air inlet pipe. The two mix and burn within the combustion chamber formed by the combustion chamber and burner head cover. The resulting flame directly heats the cookware placed on the combustion chamber, thus achieving the purpose of cooking.

[0003] The patent document with publication number CN205606548U discloses a design including: an outer stove and an inner stove; an assembly channel opening at the bottom of the inner stove; a gas concentrator ring in the middle of the inner stove; a small gas supply pipe in the gas air inlet channel and the blower pipe inlet; a dust cap at the end of the small gas supply pipe; a main gas inlet pipe arranged horizontally between the outer stove and the inner stove; the gas supply port of the main gas inlet pipe communicating with an annular gas distribution cavity between the gas air inlet channel and the assembly channel opening; and a main gas outlet on the outer wall of the annular gas distribution cavity.

[0004] In practical applications, it still has the following shortcomings: In the existing burner design, untreated ambient temperature fuel is directly injected into the combustion chamber. This type of fuel is in a low thermodynamic state and needs to absorb a large amount of heat energy from the surrounding environment in the initial combustion zone to reach the reaction conditions. This heat absorption process will drastically reduce the temperature at the flame root, and even cause the local temperature to drop below the ignition point, thereby destroying combustion stability, slowing down the reaction rate, and ultimately causing problems such as incomplete combustion and low thermal efficiency, resulting in fuel loss. Utility Model Content

[0005] This invention provides a high-efficiency burner that can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows:

[0007] A high-efficiency burner comprises: a burner shell, a combustion cylinder placed inside the burner shell, an oil injector penetrating and positioned at the center of the bottom of the burner shell, and a fuel pipe connected to the oil injector. Two ignition needles are also installed at the bottom of the burner shell. An air inlet pipe communicating with the inner cavity of the burner shell is also provided on the burner shell. A burner head cover is provided at the top opening of the combustion cylinder. Several through-holes are evenly distributed at equal intervals on the sidewalls of the combustion cylinder. The fuel pipe includes a first oil inlet section that penetrates sequentially from bottom to top through the bottom of the burner shell and the bottom of the combustion cylinder, and a second oil inlet section that is spirally distributed inside the combustion cylinder and connected to the first oil inlet section. A third oil inlet section is provided at the top of the second oil inlet section that penetrates sequentially downwards through the bottom of the combustion cylinder and the bottom of the burner shell and is connected to the oil injector. The burner head cover has several circular holes.

[0008] As a further improvement, the combustion chamber is provided with a protective cover, the fuel pipe is located outside the protective cover, a number of connecting holes are evenly distributed on the side wall of the protective cover, the connecting holes are connected to the combustion chamber, the bottom of the protective cover has a central hole corresponding to the fuel injector, and the top of the protective cover is connected to the opening of the combustion chamber.

[0009] As a further improvement, the air vent is inclined upwards.

[0010] As a further improvement, the combustion cylinder is a cylindrical structure coaxial with the burner housing, and the top is a funnel-shaped structure that opens outwards.

[0011] As a further improvement, the top of the combustion cylinder has an outwardly extending boss that engages with the opening at the top of the burner housing.

[0012] As a further improvement, the burner housing sidewall is provided with a fixing ring, and the fixing ring is provided with several mounting holes.

[0013] As a further improvement, the fuel line is made of stainless steel.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, fuel flows sequentially through a first inlet section, a second inlet section, and a third inlet section of a fuel pipe. The second inlet section has a spiral structure. During combustion, the fuel flowing through the second inlet section is heated by the high-temperature flame inside the combustion chamber, thereby bringing the fuel to the temperature of vaporization. The vaporized fuel mixes more evenly with the air, resulting in more complete combustion and faster heat transfer to the cookware. This shortens the time it takes for the cookware to be heated to the required temperature, thus improving the thermal efficiency of the entire cooking process. Attached Figure Description

The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In existing burner designs, untreated ambient temperature fuel is directly injected into the combustion chamber. This fuel is in a low thermodynamic state and needs to absorb a large amount of heat energy from the surrounding environment in the initial combustion zone to reach the reaction conditions. This endothermic process drastically reduces the temperature at the flame root, even causing the local temperature to drop below the ignition point, thereby disrupting combustion stability, slowing down the reaction rate, and ultimately leading to incomplete combustion and low thermal efficiency, resulting in fuel loss. To solve the above-mentioned technical problems, this paper proposes the following technical solution:

[0027] Reference Figures 1-6 As shown, a high-efficiency burner comprises: a burner housing 1, a combustion cylinder 2 placed inside the burner housing 1, an oil injector 3 penetrating and located at the center of the bottom of the burner housing 1, and a fuel pipe 4 connected to the oil injector 3. Two ignition needles 5 are also installed at the bottom of the burner housing 1. An air inlet pipe 6 communicating with the inner cavity of the burner housing 1 is also provided on the burner housing 1. A burner head cover 7 is provided at the top opening of the combustion cylinder 2. Several through-holes 21 are evenly distributed at equal intervals on the sidewalls of the combustion cylinder 2. The fuel pipe 4 includes a first oil inlet section 41 that penetrates the bottom of the burner housing 1 and the bottom of the combustion cylinder 2 sequentially from bottom to top, and a second oil inlet section 42 that is spirally distributed inside the combustion cylinder 2 and connected to the first oil inlet section 41. A third oil inlet section 43 is provided at the top of the second oil inlet section 42 that penetrates the bottom of the combustion cylinder 2 and the bottom of the burner housing 1 sequentially downwards and is connected to the oil injector 3. The burner head cover 7 has several round holes 71 distributed throughout.

[0028] Therefore, during use, combustion air is supplied into the burner housing 1 through the air intake pipe 6, while fuel atomization is supplied to the fuel injector 3 through the fuel pipe 4 and sprayed into the combustion cylinder 2. The combustion air enters the combustion cylinder 2 through the air hole 21, where it mixes with the atomized fuel and is ignited by the ignition needle 5. After several tens of seconds of combustion, the temperature inside the combustion cylinder 2 can reach 300-400 degrees Celsius. At this time, the fuel flows sequentially through the first fuel inlet section 41, the second fuel inlet section 42, and the third fuel inlet section 43 of the fuel pipe 4, and is finally supplied to the fuel injector 3. Since the second fuel inlet section 42 is located inside the combustion cylinder 2 and has a spiral structure, the fuel flowing through the second fuel inlet section 42 is heated by the high-temperature flame inside the combustion cylinder 2 during combustion, thereby bringing the fuel to the temperature of vaporization. The vaporized fuel and air are more evenly mixed, resulting in more complete combustion and faster heat transfer to the cookware, shortening the time it takes for the cookware to be heated to the required temperature, thus improving the thermal efficiency of the entire cooking process.

[0029] The combustion chamber 2 is equipped with a protective cover 8, and the fuel pipe 4 is located outside the protective cover 8. Several connecting holes 81 are evenly distributed on the side wall of the protective cover 8, and these connecting holes 81 are connected to the combustion chamber 2. The bottom of the protective cover 8 has a central hole 82 corresponding to the fuel injector 3, and the top of the protective cover 8 is connected to the opening of the combustion chamber 2. Therefore, the protective cover 8 can effectively prevent the flame of fuel combustion from directly contacting the fuel pipe 4, preventing thermal damage to the fuel pipe from the high-temperature flame. Secondly, the heat of combustion is transferred to the surrounding space through the wall of the protective cover 8 and the connecting holes 81, thereby indirectly heating the fuel pipe and ensuring that the fuel is stably heated and gradually vaporized during transportation. At the same time, the connecting holes 81 ensure that the combustion air can still smoothly enter the combustion chamber 2 to participate in combustion, maintaining combustion efficiency; the central hole 82 ensures that the fuel injector 3 can normally spray atomized fuel, making combustion continuous and stable.

[0030] Specifically, the protective cover 8 has a conical structure with a bottom diameter smaller than the top diameter, which helps to guide the flame and high-temperature smoke to spread upward and concentrate naturally, thereby forming a more stable and efficient combustion pattern;

[0031] The air vent 21 is inclined upwards, which guides the combustion air from inside the burner housing 1 and into the combustion cylinder 2 at high speed in a specific direction towards the combustion center area. This not only effectively enhances the turbulent mixing of fuel and air, but also helps to constrain the flame shape to be more concentrated and stable, thereby achieving full mixing and efficient combustion of the two.

[0032] The combustion cylinder 2 is a cylindrical structure coaxial with the burner shell 1, which ensures the uniform distribution of the surrounding combustion air. The top is a funnel-shaped structure that opens outward, which effectively guides the flame to spread evenly in all directions and forms a better contact surface with the bottom of the pot, thereby reducing heat loss and improving thermal efficiency.

[0033] The top of the combustion cylinder 2 has an outwardly extending boss 22 that engages with the opening at the top of the burner housing 1. The boss 22 is close to the opening at the top of the burner housing 1, which enables the combustion cylinder 2 to be precisely positioned and reliably fixed in the housing, while enhancing structural stability and helping to prevent flue gas from leaking from the connection.

[0034] The burner housing 1 has a fixing ring 11 on its side wall. The fixing ring 11 has several mounting holes 12, which are circumferentially distributed. This allows the burner to be easily installed and fixed to a designated position on the stove or support frame using fasteners such as bolts. This not only ensures a stable and reliable connection but also facilitates disassembly and maintenance in the future.

[0035] The fuel pipe 4 is made of stainless steel. Stainless steel has good thermal conductivity, mechanical strength and corrosion resistance, which allows it to efficiently transfer the heat required for preheating and withstand the mechanical stress during installation and operation.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
