Abstract
Description
Technical Field
[0001] This invention relates to a burner for a gas stove, and more particularly to a stainless steel sheet metal burner assembly. Background Technology
[0002] Currently, most gas stove burners and burners used in the domestic stove market are composed of die-cast aluminum, cast aluminum, or forged copper burner bodies with copper burner caps. Given the current high price of copper, these products suffer from high material costs and heavy emissions. Patent No. 2023216652090 introduced a burner made entirely of stainless steel, but due to some structural design issues and the fact that the matching burner is still made entirely of copper, it suffers from defects such as the inability to provide secondary combustion air, unclear flame combustion, incomplete combustion, excessive smoke, and high cost. Summary of the Invention
[0003] The purpose of this invention is to provide a stainless steel sheet metal combustion assembly that is structurally reasonable, uses less material, is low-cost, environmentally friendly and energy-saving, resistant to high temperatures, has high combustion thermal efficiency, and produces a clear combustion flame.
[0004] To achieve the above objectives, the present invention is implemented through the following technical solution. A stainless steel sheet metal combustion assembly includes a sheet metal burner and a stainless steel anti-dry-burning burner head. The sheet metal burner includes a large-fire upper shell, a large-fire guide plate, a large-fire lower shell, a large-fire base, a small-fire upper shell, a small-fire guide plate, and a small-fire base, all made of stainless steel. The large-fire upper shell is located at the top of the burner, with an outer ring that is segmented and has a central hollowed-out annular shell. The large-fire guide plates are correspondingly spaced below the large-fire upper shell. The large-fire lower shell is located below the large-fire guide plates, and the large-fire base is located below the large-fire lower shell. The large-fire upper shell, large-fire guide plates, and large-fire lower shell are stacked to form an integrated structure. The small-fire base is located above the large-fire upper shell, the small-fire guide plates are located above the small-fire base, and the small-fire upper shell is located above the small-fire guide plates.
[0005] The stainless steel sheet metal combustion assembly has an upper flame shell that is annular with 3-10 segments on the outer ring and a hollow center. The flame port is located on the outer ring conical surface, and the flame propagation port is located on the radial inclined surface and the inner ring conical surface. Three oval countersunk holes are located in the middle ring, with an upper oval through hole at the bottom of each countersunk hole. A small flame through hole is located in the center. The segmented bottom plane of the top of the flame guide plate is tightly attached to the segmented bottom plane of the upper flame shell. The outer ring vertical surface is riveted to the outer ring of the upper flame shell. The middle ring vertical surface has 10-30 outer guide holes, forming an inner flame guide inlet between its inner ring and the inner ring of the upper flame shell. The lower flame shell is a disc with an oval boss, and a flame through hole is located in the center. The central ring has three oval-shaped bosses, with a lower oval-shaped through hole in the middle of each boss. The upper shell, the guide plate, and the lower shell of the large flame are stacked and riveted together in reverse with U-shaped rivets to form an integrated structure. The top vertical surface of the large flame base is riveted to the large flame through hole of the lower shell. The bottom inner ring vertical surface is fitted and sealed to the outer vertical surface of the large flame channel of the stainless steel anti-dry-burning burner head. The bottom surface of the oval-shaped countersunk hole of the upper shell of the large flame coincides with the top surface of the oval-shaped boss of the lower shell of the large flame. The cavity formed by the groove between the oval-shaped countersunk holes of the upper shell of the large flame and the groove between the oval-shaped bosses of the lower shell of the large flame is the large flame channel. The upper oval-shaped through hole and the lower oval-shaped through hole are coaxially aligned and riveted together in reverse with U-shaped rivets to form a secondary air channel.
[0006] The stainless steel sheet metal combustion assembly has a small flame base that is annular. Its inner hole fits with the outer ring of the small flame tube of the stainless steel anti-dry-burning burner head. Its lower vertical surface is riveted and fixed to the small flame tube of the upper shell of the main flame. The outer ring of the small flame guide plate fits with the end face of the outer ring of the small flame base. The inner ring forms a small flame guide inlet between the inner ring and the outer ring of the anti-dry-burning tube of the stainless steel anti-dry-burning burner head. The upper shell of the small flame is a frustum-shaped conical shell. Its outer conical surface has small flame holes. The inner vertical surface fits and seals with the inner surface of the anti-dry-burning tube of the stainless steel anti-dry-burning burner head. The outer vertical surface is riveted to the outer ring of the small flame guide plate and the outer ring of the small flame base.
[0007] The stainless steel sheet metal combustion assembly described above has a U-shaped riveting ring reverse riveting process as follows: the L-shaped riveting ring is placed on the upper part of the upper waist-shaped through hole after the upper shell, the upper guide plate, and the lower shell of the large flame are riveted together, and then pre-riveting is performed using equipment. Finally, the riveting ring is pressed into a U-shape and clamped for positioning.
[0008] The present invention, by adopting the above-mentioned technical solutions, has the following beneficial effects: (i) the innovative design of the ring-shaped segmented design of the upper shell gear of the large flame makes the burner feel heavy and at the same time makes the combustion flame clear and blue; (ii) the innovative design of the synchronous flow guidance and contour design of the inner and outer sides of the large flame guide plate makes the gas pressure distribution uniform and the flame combustion state clear; (iii) the innovative design of the inner side flow guidance and contour design of the small flame guide plate makes the gas pressure distribution uniform and the flame combustion state clear; (iv) the innovative design of the U-shaped riveting ring structure, after the U-shaped riveting ring is reversed and tightened, makes the upper shell of the large flame, the lower shell of the large flame, and the U-shaped riveting ring form a four-layer riveted integrated structure, which has the advantages of simple process, stable and firm structure and airtight sealing, and solves the problem of the oval shape of the upper shell of the large flame being heavy. (v) The problem is that the depth of the countersunk hole in the upper shell and the lower shell of the fire is too deep, and it cannot be riveted by conventional riveting methods; (vi) Due to the innovative design of three countersunk hole structures in the upper shell of the fire and three countersunk boss structures in the lower shell of the fire, three gas passages are formed in the middle after the upper shell and the lower shell of the fire are riveted, and three secondary air passages are formed on the outside, which solves the defect of the traditional stainless steel burner that the gas intake passage can only be entered by the independent side opening, resulting in uneven gas pressure; (vi) Due to the innovative design that the entire burner is made of stainless steel, the overall weight can be reduced by 70% compared with the all-copper burner, which has a huge cost reduction advantage. At the same time, it has excellent properties of high temperature resistance and corrosion resistance. In terms of production process, it has the characteristics of high production efficiency, mass production, no pollution, low energy consumption and environmental protection.
