Description

A burner with an independent internal and external gas distribution plate structure Technical Field

[0001] This utility model relates to the field of stove burner technology, and in particular to a burner with an independent internal and external gas distribution plate structure. Background Technology

[0002] As the core gas supply component of a gas stove, the burner's zoning structure of its inner and outer ring flames directly affects combustion efficiency and flame pattern. Traditional burners typically employ an integrated gas distribution plate design, where the inner and outer ring gas distribution plates are connected by a central beam to form a single structure, and installation and positioning are achieved through the use of positioning ears, ignition needles, and thermocouples. While this design ensures the coaxial alignment of the inner and outer ring burner caps and the injector tube, it has significant technical drawbacks: First, the connecting beam occupies the central area of ​​the burner, obstructing the secondary air supply channel and leading to oxygen deficiency during combustion, thus affecting CO emission standards; second, for burners with different burner hole arrangements or sizes, a completely new gas distribution plate mold needs to be developed, resulting in extended development cycles and increased production costs.

[0003] Therefore, further improvements are needed. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a burner with an independent internal and external gas distribution plate structure.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a burner with an independent inner and outer gas distribution plate structure, including: a burner head, an inner ring gas distribution plate, an outer ring gas distribution plate and a water pan body;

[0006] The burner head includes a burner base plate, an inner ring ejector tube, and an outer ring ejector tube; the gas outlets of the inner ring ejector tube and the outer ring ejector tube are respectively inserted into the inner ring gas distribution plate and the outer ring gas distribution plate; the burner base plate is provided with at least two water tray connection holes; the water tray body is installed on the stove panel and locked to the water tray connection holes by water tray bolts;

[0007] Several outer ring positioning cylinders are provided below the outer ring air distribution plate, and the positions of the outer ring positioning cylinders correspond one-to-one with the water plate connection holes; the lower part of the outer ring positioning cylinder can be sleeved on the end of the water plate bolt.

[0008] Optionally, the water tray connection hole is provided with at least 3 holes, which are evenly arranged circumferentially on the outer periphery of the air outlet end of the inner ring ejector tube.

[0009] Optionally, the inner ring gas distribution plate and the outer ring gas distribution plate are respectively covered with a center flame cap and an outer ring flame cap; the center flame cap has a round bowl-shaped structure, and the outer ring flame cap has a ring-shaped structure.

[0010] Optionally, the furnace base plate is provided with an ignition needle and a thermocouple.

[0011] Optionally, the inner wall of the outer ring air distribution plate is provided with several turbulence ribs.

[0012] The beneficial effects of this utility model are as follows: The inner and outer ring gas distribution plates adopt an independent split structure. The outer ring gas distribution plate is directly positioned by fitting the outer ring positioning cylinder to the end of the water pan bolts, while the inner ring gas distribution plate can be independently aligned and installed based on the furnace base plate. This design allows the inner and outer ring gas distribution plates to be manufactured separately by mold, significantly reducing the number of molds required and enabling rapid adaptation to different specifications of burners. The modular design reduces costs and increases efficiency. By eliminating the traditional connecting beam structure between gas distribution plates, the secondary air supply channel in the central area of ​​the burner is completely opened up, resulting in uniform air distribution along the circumference, effectively improving gas mixing efficiency and flame combustion stability.

[0023] Example

[0024] Referring to Figures 1 and 2, the present invention proposes a burner with an independent inner and outer gas distribution plate structure, comprising: a burner head 10, an inner ring gas distribution plate 20, an outer ring gas distribution plate 30, and a water pan body 40.

[0025] The burner head 10 includes a burner base plate 11, an inner ring ejector tube 12, and an outer ring ejector tube 13; the gas outlets of the inner ring ejector tube 12 and the outer ring ejector tube 13 are respectively inserted into the inner ring gas distribution plate 20 and the outer ring gas distribution plate 30; the burner base plate 11 is provided with at least two water pan connection holes 14; the water pan body 40 is installed on the cooktop panel 50 and locked to the water pan connection holes 14 by water pan bolts 41;

[0026] Several outer ring positioning cylinders 31 are provided below the outer ring air distribution plate 30. The positions of the outer ring positioning cylinders 31 and the water plate connection holes 14 correspond one-to-one. The lower part of the outer ring positioning cylinders 31 can be sleeved on the end of the water plate bolt 41.

[0027] In this invention, the inner and outer ring gas distribution plates 30 adopt an independent split structure. The outer ring gas distribution plate 30 is directly positioned by the outer ring positioning cylinder 31 and the end of the water pan bolt 41. The inner ring gas distribution plate 20 can be independently aligned and installed based on the furnace base plate 11. This design allows the inner and outer ring gas distribution plates 30 to be manufactured separately by mold, significantly reducing the number of molds required and enabling rapid adaptation to different specifications of burners. The modular design reduces costs and increases efficiency. By eliminating the traditional connecting beam structure between gas distribution plates, the secondary air supply channel in the central area of ​​the burner is completely opened up, resulting in uniform air distribution along the circumference, effectively improving the gas mixing efficiency and flame combustion stability.

[0028] In this embodiment, at least three water pan connection holes 14 are provided, evenly arranged circumferentially around the outer periphery of the gas outlet end of the inner ring injector 12. Providing at least three evenly distributed circumferential water pan connection holes 14 ensures uniform stress distribution between the water pan body 40 and the furnace base plate 11, preventing structural deformation due to localized stress concentration and enhancing the overall seismic resistance of the burner. The circumferentially symmetrical layout further optimizes the concentricity of the outer ring gas distribution plate 30 and the outer ring positioning cylinder 31, ensuring the coaxial alignment accuracy of the outer ring burner cap 70 and the injector, and improving the uniformity of gas distribution.

[0029] In this embodiment, the inner ring gas distribution plate 20 and the outer ring gas distribution plate 30 are respectively covered with a central flame cap 60 and an outer ring flame cap 70; the central flame cap 60 has a round bowl-shaped structure, and the outer ring flame cap 70 has an annular structure. The round bowl-shaped structure of the central flame cap 60 can concentrate the heat of the inner ring flame, forming a stable cohesive combustion, which is suitable for heating small pots and pans; the annular structure of the outer ring flame cap 70 can achieve a large-area uniform flame distribution, which is suitable for large-diameter cookware such as woks and avoids local overheating. The independent design of the two caps allows for a wider range of heat adjustment, and the separate structure makes it easy to disassemble, clean or replace them individually, extending their service life.

[0030] In this embodiment, an ignition needle 80 and a thermocouple 90 are installed through the furnace base plate 11. The ignition needle 80 and the thermocouple 90 are directly installed through the furnace base plate 11, which shortens the response distance between the ignition needle 80 and the burner cap, and between the thermocouple 90 and the flame, thereby improving the ignition success rate and the sensitivity of the thermocouple 90 to the flame status. At the same time, this layout avoids the dependence of the traditional positioning ear on the gas distribution plate structure, simplifies the assembly process, and reduces the risk of ignition failure caused by deformation of the positioning ear.

[0031] Specifically, the inner wall of the outer ring gas distributor 30 is provided with several baffles 32. The baffles 32 on the inner wall of the outer ring gas distributor 30 can form multi-level vortex disturbances on the gas flow, promoting the premixing effect of gas and air; at the same time, the baffles 32 can enhance the structural strength of the gas distributor, suppress resonance noise caused by high-frequency combustion vibration, and improve product durability and user comfort.

[0032] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
