Description

Technical Field

[0001] This utility model belongs to the field of burner technology, specifically relating to a burner for a cooking stove. Background Technology

[0002] As people's demands for the thermal efficiency, energy saving, and safety of kitchen stoves continue to increase, the burner structure of gas stoves is also constantly being improved. Currently, a widely used structure is the 360° internal combustion burner, which primarily uses an internal cavity for premixing and combustion, forming a ring-shaped flame to envelop the bottom of the pot for heating. However, this type of burner still has many shortcomings in actual use, affecting its thermal efficiency, service life, and combustion stability.

[0003] Inappropriate air intake direction: Traditional 360° internal burners generally adopt a straight air intake method, which leads to insufficient initial mixing of air and gas, easily causing problems such as uneven combustion or yellow flame, and also restricts the layout of gas passage.

[0004] Limited premixing space: Due to structural limitations, the volume of the premixing chamber is limited, resulting in poor mixing of gas and air. This makes it impossible to achieve efficient and uniform premixed combustion, directly affecting combustion efficiency and flame stability.

[0005] Uneven heat distribution: Existing internal combustion structures often result in flames that are biased to one side or uneven heat distribution, causing uneven heating of the pot bottom, which affects the cooking effect and may even cause backfire or flameout in severe cases.

[0006] The problem of high temperature accumulation is serious: because the flame burns in close contact with the surface of the metal burner, the heat is concentrated, resulting in extremely high temperatures inside the burner and furnace. This not only easily causes thermal deformation or ablation of components, but also poses a high safety hazard.

[0007] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0023] like Figures 1 to 4As shown, a burner includes a combustion body 10 and an air intake pipe 20. One end of the air intake pipe 20 is provided with a connecting screw 21, which connects to the lower end of the combustion body 10. A gas connection hole 22 is provided on the side of the air intake pipe 20. A flame outlet 11 is provided in the middle of the combustion body 10, corresponding to the connecting screw 21. In use, the end of the air intake pipe 20 is connected to a blower via a pipe, and the gas connection hole 22 is connected to a gas cylinder via a pipe. Pressurized air provided by the blower enters the air intake pipe 20 and mixes with the gas introduced from the gas connection hole 22 to form a combustible mixture. The mixed gas enters the premixing space inside the combustion body 10 through a duct structure and, under pressure, is gradually pushed from the bottom to the flame outlet 11 in the middle of the combustion body 10 for combustion.

[0024] In practical implementation, the flame outlet 11 includes a flame outlet ring column 111, a flame inlet bottom ring 112, and a flame outlet top plate 113. The flame inlet bottom ring 112 is installed at the bottom of the flame outlet ring column 111, and the flame outlet top plate 113 is installed at the top of the flame outlet ring column 111. The flame outlet ring column 111 is composed of several flame outlet ring elements 111a and several flame-insulating ring elements 111b. The flame-insulating ring elements 111b and the flame outlet ring elements 111a are stacked alternately to form a composite columnar structure with multi-level flame guiding and flame-insulating functions. Several fixed connecting posts 111c are connected to the inner side of the flame outlet ring column 111. The fixed connecting posts 111c are fixed to the flame outlet ring elements 111a and the flame-insulating ring elements 111b by welding, thereby firmly connecting the entire flame outlet ring column 111 structure into one unit. During operation, air and fuel gas undergo preliminary mixing in the air intake pipe 20 before entering the combustion body 10 from the bottom. The mixture is then guided through the bottom fire ring 112 into the premixing space inside the fire outlet ring column 111. The gas is evenly released through the gaps between the fire outlet rings 111a, forming an annular flame. The flame releases heat layer by layer from bottom to top and is concentrated and ejected through the top fire outlet plate 113. This multi-stage annular fire outlet design results in a more uniform and three-dimensional flame output, with concentrated and unbiased firepower. The multiple layers of fire-resistant rings 111b effectively block the downward conduction of high-temperature heat, reducing thermal stress concentration, effectively extending burner life, and improving overall thermal efficiency and structural durability.

[0025] In practical implementation, the combustion body 10 includes a mounting shell 12 and a mounting bottom cover 13. The mounting bottom cover 13 is installed at the bottom of the mounting shell 12, forming a lower closed structure of the combustion body. The flame outlet 11 is installed in the middle of the mounting shell 12 for concentrated flame output. A heat insulation base plate 14 is installed at the bottom of the flame outlet 11 for isolating high temperatures. Heat insulation cotton 15 is provided at the bottom of the heat insulation base plate 14, and the heat insulation cotton 15 is disposed between the heat insulation base plate 14 and the mounting bottom cover 13 for increasing heat insulation capacity. The heat insulation provides strong insulation, preventing heat conduction to the bottom of the outer casing and protecting the structure and surrounding components. The inner side of the heat insulation base plate 14 is provided with a connecting thread 141 that is compatible with the connecting screw head 21. The connecting thread 141 and the connecting screw head 21 are connected and fixed by a threaded engagement, thereby connecting the air intake pipe 20 to the combustion body 10. In use, the heat insulation cotton 15 and the heat insulation base plate 14 work together to effectively block the downward conduction of flame heat, protect the mounting bottom cover 13 and the overall structure, and extend the product life.

[0026] In practical implementation, the inner side of the mounting shell 12 is provided with heat-insulating cotton 16, which is used to completely cover the internal structure of the combustion body 10, serving a dual function of heat insulation and heat preservation. An inner heat-insulating ring 17 is installed on the inner side of the heat-insulating cotton 16, which is attached to the outside of the combustion core area to further improve heat insulation performance and prevent heat leakage to the mounting shell 12. A fixing ring 18 is installed on the top of the mounting shell 12, the heat-insulating cotton 16, and the inner heat-insulating ring 17 to press and fix the heat insulation layer assembly, ensuring that it does not shift or deform during use and enhancing the overall structural stability. During use, because the flame forms a 360-degree three-dimensional external combustion structure in the area of ​​the flame outlet 11, the heat is mainly concentrated in the central area of ​​the combustion body 10. The structure of the heat insulation cotton 16 on the inner side of the mounting shell 12, the inner heat insulation ring 17, and the top fixing ring 18 effectively constructs a multi-layer thermal protection system, which not only prevents high temperature from being directly conducted to the outside of the metal shell and protects the shell material from being damaged by high temperature, but also plays the role of constant temperature heat preservation and improving combustion efficiency.

[0027] In practical implementation, several first mounting brackets 19 are installed on the outer side of the combustion body 10 to securely install the combustion body 10 on the stove platform or support structure. A second mounting bracket 23 is installed on the outer side of the air intake pipe 20 to assist in fixing the air intake pipe 20, guide its installation direction, and prevent it from shaking or loosening due to airflow impact or external force interference during use.

[0028] In summary, the combustion body 10 has a flame outlet 11 in its middle. The flame outlet 11 includes a flame outlet ring column 111, a flame inlet bottom ring 112, and a flame outlet top plate 113. The flame inlet bottom ring 112 is installed at the bottom of the flame outlet ring column 111, and the flame outlet top plate 113 is installed at the top of the flame outlet ring column 111. The flame outlet ring column 111 is composed of several flame outlet ring members 111a and several flame-separating ring members 111b. A heat-insulating base is installed at the bottom of the flame outlet 11. The heat-insulating base plate 14 has heat-insulating cotton 15 at its bottom and heat-insulating cotton 16 on the inner side of the mounting shell 12. An inner heat-insulating ring 17 is installed on the inner side of the heat-insulating cotton 16. The burner of this utility model optimizes the air intake path, designs a multi-stage premixing chamber and heat-insulating structure, and realizes a 360-degree three-dimensional external combustion mode, thereby achieving uniform fire after the fire is concentrated and the heat is even after the pressure cooker is heated, which improves the combustion efficiency, makes it more energy-saving, more efficient, more environmentally friendly, and extends its service life.
