Description

Technical Field

[0001] This utility model relates to a gas stove accessory, specifically a high-efficiency gas stove burner cap structure. Background Technology

[0002] Gas stoves are widely used kitchen appliances in modern kitchens, and the burner cap is its core component, directly affecting combustion efficiency, heat distribution, and heat utilization. Traditional gas stove burner caps often have flame holes designed in a single direction, such as only vertical or a single angled flame hole. This design results in a single-direction flame, with heat concentrated in a localized area at the bottom of the pot, making it difficult to achieve even heating of the entire pot. This not only reduces cooking efficiency but also affects the cooking results, easily causing food to overheat and burn. Furthermore, the unscientific design of the flame hole's position leads to insufficient mixing of flame and air, directly resulting in incomplete combustion of gas, wasting gas, and increasing household costs.

[0009] A transitional inclined hole is provided between the upper end face of the outer ring flame cap and its outer cylinder, and the outer ring inclined flame hole is provided on the transitional inclined hole.

[0010] The upper surface of the outer ring fire cover is provided with several equidistantly distributed air guide platforms, and an air guide zone is formed between adjacent air guide platforms.

[0011] The aforementioned outer ring vertical fire holes are set on the air guide platform.

[0012] The air guide platform has a recessed area in the middle that extends downwards, and the recessed area extends through the outer side of the air guide platform.

[0013] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness. 2. Multi-layered flame rings cover more combustion areas, resulting in more comprehensive and even heating of the pot bottom. 3. The coordinated operation of the angled and vertical flame holes ensures more thorough mixing of the gas, improving combustion rate and resulting in significant energy-saving and environmental protection effects. 4.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings. A high-efficiency gas stove burner cover structure includes an outer ring burner cover 1 and a central burner cover 2. The outer ring burner cover 1 is provided with an outer ring oblique flame hole 11 and an outer ring vertical flame hole 12.

[0019] The central flame cap 2 is provided with an inner ring oblique flame hole 21 and an inner ring vertical flame hole 22.

[0020] The outer ring inclined flame hole 11 and the inner ring inclined flame hole 21 are inclined outward at 45°-60°.

[0021] The outer ring vertical fire hole 12 and the inner ring vertical fire hole 22 spray flames upward in a vertical direction.

[0022] The outer ring oblique flame holes 11 and the outer ring vertical flame holes 12 on the outer ring flame cap 1 are arranged alternately, and the inner ring oblique flame holes 21 and the inner ring vertical flame holes 22 on the central flame cap 2 are arranged alternately.

[0023] A transitional inclined hole 13 is provided between the upper end face of the outer ring flame cap 1 and its outer cylinder, and the outer ring inclined flame hole 11 is provided on the transitional inclined hole 13.

[0024] The upper surface of the outer ring fire cover 1 is provided with several equidistantly distributed air guide platforms 3, and an air guide zone is formed between adjacent air guide platforms 3.

[0025] The outer ring vertical fire hole 12 is set on the air guide platform 3.

[0026] The air guide platform 3 has a recessed area 4 in the middle, which extends downwards and penetrates the outer side of the air guide platform 3.

[0027] Working Principle: Unlike traditional gas burner designs, the burner in this case includes an outer ring burner and a central burner. The outer ring burner features an outer ring of oblique flame holes and an outer ring of vertical flame holes, evenly distributed around its circumference to form the first and second flame rings, respectively. The central burner features an inner ring of oblique flame holes and an inner ring of vertical flame holes, evenly distributed around its circumference to form the third and fourth flame rings, respectively. This four-ring burner design significantly expands the heat coverage area and provides richer heat levels compared to the traditional three-ring burner design, reducing temperature differences across different parts of the pot and significantly improving the cooking effect of the gas stove.

[0028] The outer and inner ring inclined flame holes are set at an outward tilt of 45°-60°. The gas is ejected at an angle through the tilt angle, and the flame spreads outward at an angle, forming an outward fire coverage on the bottom of the pot. During the injection process, the gas can fully contact the surrounding air, which promotes the mixing of gas and oxygen and avoids the generation of harmful gases due to incomplete combustion. The gas combustion rate is high, which has significant energy-saving and environmental protection effects.

[0029] The outer and inner ring vertical burner holes are vertically distributed, working in conjunction with the outer and inner ring oblique flame holes to form a cross-over flame distribution. Compared to the traditional single-direction flame jet of a burner cap, the vertical burner holes provide stable central heat to ensure consistent flame output, while the oblique flame holes guide the gas outward to avoid direct impact on the burner cap and pot, achieving multi-level coordination of heat. Users can flexibly switch between different heat modes by adjusting the gas flow according to actual cooking needs, such as high heat for rapid stir-frying or low heat for slow simmering. Furthermore, the outer ring oblique flame holes and outer ring vertical burner holes on the outer burner cap are arranged alternately, as are the inner ring oblique flame holes and inner ring vertical burner holes on the central burner cap. This staggered arrangement of the burner holes on both burner caps further enhances the uniformity and controllability of the heat distribution. This burner cap can meet diverse cooking scenarios, improving the practicality of the gas stove and the user experience.

[0030] Furthermore, the upper surface of the outer ring burner cap features several equidistantly distributed air guide platforms, forming air guide zones between adjacent platforms. Vertical burner holes are distributed along these platforms. These platforms improve the burner cap's heat dissipation performance, enhance airflow, and ensure more thorough mixing and stable combustion of the gas, reducing safety hazards caused by overheating and making the gas stove safer and more reliable. A recessed clearance zone is recessed in the center of the air guide platform, extending through its outer surface. This clearance zone forms a self-cleaning channel, effectively reducing the accumulation of oil or food at the burner holes, lowering the risk of blockage, and providing strong anti-clogging capabilities. This extends the burner cap's lifespan and reduces the frequency of cleaning and maintenance, making it widely applicable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
