Gas cooker

Abstract

The invention relates to a gas cooker which comprises a liquid receiving disk, a furnace end, an inner fire cover, an outer fire cover and an outer ring distributor, wherein an extending hole of a burner is formed in a central boss of the liquid receiving disk; left-handed or right-handed inner fire grooves are formed in the inner ring wall of the outer fire cover; or the left-handed or right-handed inner fire grooves are formed in the inner ring wall of the outer fire cover, and outer fire holes are formed in the outer ring wall of the outer fire cover; and areas of the inner fire grooves in the outer fire cover account for 30%-100% of those of the outer fire holes. With the adoption of the structure, secondary air enters space between the inner fire cover and the outer fire cover via a gap between the outer ring distributor and the furnace end, and is contacted with gas sprayed by inner flame fire holes; the burning process is realized; another part of secondary air enters from the outside of the outer fire cover, and is contacted with the unburned gas of the inner flame fire holes and gas sprayed outward by the outer fire cover, thus complete burning is accomplished; and high-temperature flue gas formed after gas burning transmits heat to a heating kettle through convection and heat radiation, thus heat exchange is realized, the heating process is finished and the working efficiency is improved.

Description

technical field [0001] The invention relates to an internal swirl fire cooker burner. Background technique [0002] In the current prior art, a burner for an inner pyrotechnic stove includes a liquid receiving tray and a burner. The burner includes a burner head, an inner fire cover, an inner rotating outer fire cover and an outer ring distributor. Air cavity, inner distributor, inner injection pipe and outer introduction pipe, the inner injection pipe communicates with the inner distributor, the outer injection pipe communicates with the outer ring air mixing chamber; there is a left-handed or rotating combustion groove on the outer fire cover. The problem is that when the gas flame is sprayed to the center of the heating pot, the air supply inside the outer ring of the cooker is insufficient, resulting in most of the gas flame not being able to contact enough secondary air in time, causing the high temperature area of ​​the gas to extend to the periphery of the heated pot,...

AI Technical Summary

Problems solved by technology

The problem is that when the gas flame is sprayed to the center of the heating pot, the air supply inside the outer ring of the cooker is insufficient, resulting in most of the gas flame not being able to contact enough secondary air in time, causing the high temperature area of ​​the gas to extend to the periphery of the heated pot, and the heating efficiency Reduced; limited by the structure of the burner, the circumferentially uniform gas sprayed from the burner is in contact with the circumferentially uneven secondary air. Due to the existence of local locations, the gas flame and the secondary air are not mixed uniformly, resulting in uneven combustion of the gas. Uniform combustion, in order to ensure that harmful components such as carbon monoxide in the flue gas are lower than the product technical standard requirements, the total air supply required for combustion can only be increased, which will also reduce the efficiency of the gas stove
