Description

Technical Field

[0001] The utility model relates to a gas stove accessory, in particular to a burner for a gas stove. Background Art

[0002] Gas stoves are common cooking appliances in modern kitchens. They primarily utilize burners to efficiently burn gas to meet cooking needs. The design of a gas stove burner directly impacts combustion uniformity, efficiency, and safety. In the prior art, a gas stove burner typically consists of a diffuser, an outer ring diffuser cover, and an inner ring diffuser cover. These components work together to ensure that the gas is fully mixed within the diffuser before burning through the combustion holes, generating a flame.

[0003] In traditional gas stove burners, the flame distributor, outer ring flame distributor cover, and inner ring flame distributor cover mostly use a simple snap-on structure. While this design is relatively convenient during assembly, it has the following drawbacks. These drawbacks can easily lead to performance degradation and even pose safety risks, especially over long-term use.

[0004] 1. The connection between the ignition distributor and the outer and inner ring ignition distributor covers in existing gas stoves is mostly achieved through a simple interlocking method. This lacks an effective fixing method, causing the ignition distributor cover to loosen or fall off easily during long-term use or frequent cleaning. Once the ignition distributor cover becomes loose or shifted, it not only affects the normal combustion of the gas, but also causes uneven combustion and unstable flame distribution.

[0005] A loose connection between the ignition distributor and the ignition cover not only affects combustion efficiency but also creates the risk of gas leaks. Because the snap-fit ​​mechanism lacks a tight seal, if it becomes loose, gas could leak from the joint, increasing the risk of gas leaks. Gas leaks are a potential safety threat in the kitchen, especially in high-temperature environments, and can cause fires or explosions.

[0006] 3. Because the snap-fit ​​mechanism isn't completely sealed, foreign matter, such as food debris and dust, can easily enter the gap between the ignition distributor and the cover during daily use. These foreign objects can clog the combustion holes, affecting the proper flow and mixing of gases, leading to unstable flames or even flameout. Furthermore, these foreign objects can further prevent the cover from locking securely, increasing the chance of it coming loose. Therefore, further improvements are necessary. Utility Model Content

[0030] Among them, the bottom of the inner ring fire cover 4 extends downward to have a lower connecting ring 41 connected to the second isolation ring 12, and a plurality of rings of inner combustion hole rings 42 distributed in an annular shape are arranged on the cylindrical surface of the lower connecting ring 41, and the combustion holes in adjacent rings are staggered left and right.

[0031] In one embodiment, the outer combustion hole ring 6 is provided with four rings, which are distributed from top to bottom, namely the first outer combustion hole ring 61, the second outer combustion hole ring 62, the third outer combustion hole ring 63, and the fourth outer combustion hole ring 64.

[0032] In one embodiment, the diameter of the outer combustion hole ring 6 is gradually reduced from top to bottom.

[0033] In one embodiment, the outer connecting ring 31 is in a conical shape with a larger bottom and a smaller top.

[0034] In one embodiment, the ignition distributor 1 is provided with a plurality of outer ring fixing holes 14 , and the bottom of the outer ring ignition distributor cover 3 is provided with a plurality of outer ring screw holes 33 , and the fixing screws pass through the outer ring fixing holes 14 and are fixed to the outer ring screw holes 33 .

[0035] In one embodiment, the outer cylindrical surface of the lower connecting ring 41 is a conical configuration with a larger bottom and a larger top. The inner combustion hole ring 42 is provided with two rings, and the inner combustion holes on the two adjacent rings are staggered left and right.

[0036] In one embodiment, a first covering platform 44 and a second covering platform 45 are extended outward from the outer cylindrical surface of the lower connecting ring 41 , and an ignition groove 36 is provided through the upper and lower end surfaces of the first covering platform 44 and the second covering platform 45 .

[0037] In one embodiment, the first covering platform 44 and the second covering platform 45 are provided with air guide holes 37 through their inner and outer end surfaces, and the air guide holes 37 are in communication with the outer ring gas mixing cavity 5 .

[0038] In one embodiment, a positioning groove 15 is provided on the second isolation ring 12 , and the first cover platform 44 and the bottom of the second cover are clamped and installed in the positioning groove 15 .

[0039] In one embodiment, the ignition distributor 1 is provided with an inner ring fixing hole 16 , and the bottom of the inner ring ignition distributor cover 4 is provided with an inner ring screw hole 43 , and the fixing screw passes through the inner ring fixing hole 16 and is fixed to the inner ring screw hole 43 .

[0040] Working Principle: During use, gas enters the burner from the gas source and, guided by the ignition distributor 1, is thoroughly mixed with air in the outer ring mixing chamber 5. The outer ring mixing chamber is formed by the ignition distributor 1, the first docking ring 13, the inner connecting ring 32, and the first isolation ring 11. This chamber design ensures that the gas and air are fully mixed, providing a high-quality gas-air mixture for the subsequent combustion process.

[0041] The combustion process is primarily achieved through the combustion holes in the outer and inner rings of the fire distributor cover 3 and 4. The outer connecting ring 31 of the outer fire distributor cover is equipped with several rings of outer combustion holes 6 arranged in an annular pattern, with adjacent rings of combustion holes offset left and right. This staggered design ensures even flame distribution and more complete combustion. Furthermore, the lower connecting ring 41 of the inner ring fire distributor cover is also equipped with several rings of inner combustion holes 42, similarly offset left and right between adjacent rings of inner combustion holes, further ensuring combustion uniformity in the inner ring area.

[0042] Due to the optimized design of the outer combustion ring and the inner combustion ring, the burner can ensure uniform distribution of flame during operation, greatly improve the combustion efficiency, and avoid the phenomenon of uneven flame or local overheating.

[0043] In traditional gas burner burners, the ignition distributor, outer ring ignition cover, and inner ring ignition cover typically utilize a simple snap-fit ​​mechanism, which can easily come loose, leading to leaks or performance degradation. In contrast, in the present utility model, the outer ring ignition cover 3 is securely docked with the first docking ring 13 via its outer connecting ring 31, and secured with setscrews through the outer ring fixing holes 14 and outer ring threaded holes 33. Furthermore, the inner ring ignition cover 4 is also docked with the second isolation ring 12 via a lower connecting ring 41, and similarly secured with screws to ensure structural stability.

[0044] This fixed screw connection structure not only effectively avoids the problem of loosening of the ignition cover, ensuring the stability of the components during high temperature and long-term use, but also improves the safety of gas combustion and avoids the risk of gas leakage.

[0045] Furthermore, the installation of first and second isolation rings 11, 12 on the ignition distributor 1 creates a multi-layered isolation structure, effectively preventing foreign matter such as dust and food residue from entering the burner. The design of the inner and outer connecting rings 32, 31, and the ignition distributor cover completely encloses the gas flow path within the structure, further preventing external contaminants from entering the gas passage and combustion area.

[0046] The multiple designs of the isolation structure greatly reduce the possibility of combustion hole blockage caused by foreign matter entering the burner, keep the combustion hole unobstructed, and thus ensure the stability of the combustion process and flame uniformity.

[0047] In addition, the present invention also provides a first cover platform 44 and a second cover platform 45 on the outer cylindrical surface of the lower connecting ring 41, and an ignition groove 36 is provided through its upper and lower end surfaces. These covers can provide a protective shield for the ignition needle and thermocouple, preventing them from being impacted or contaminated, thereby ensuring their service life. In addition, the ignition groove guides the flow of gas, allowing the gas to be evenly distributed to each combustion hole during ignition, ensuring a smooth and stable ignition process. At the same time, the cover platform is also provided with a gas guide hole 37, which is connected to the outer ring mixing chamber 5, further optimizing the gas flow and improving the air mixing effect of the burner.

[0048] By providing the ignition slot and gas guide holes, this utility model greatly improves the stability of gas ignition and the accuracy of temperature detection by the thermocouple, avoiding problems such as ignition difficulty and flame instability. This optimized design ensures that the gas burner ignites quickly and stably when started, improving the user experience.

[0049] The outer and inner ring flame distributor caps are securely connected to the ignition distributor via set screws, enhancing the connection's strength and simplifying cleaning and maintenance. Users can easily remove the caps for cleaning, preventing the accumulation of foreign matter that could affect combustion. Furthermore, this design significantly reduces the risk of loosening, air leaks, and foreign matter intrusion, extending the burner's service life.

[0050] Compared with traditional snap-on burners, the screw-on fixing structure of the utility model significantly improves the durability of the burner, reduces the maintenance cost in long-term use, is more convenient for users to clean, and extends the service life of the equipment, so it can be widely promoted and used.

[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
