Single-ring fire burner

Abstract

The invention relates to a single-ring fire burner and belongs to the technical field of kitchen ranges. The single-ring fire burner comprises a furnace end and a fire cover arranged on the furnace end; the furnace end is provided with a thick injecting pipe and a thin injecting pipe; the thick injecting pipe is communicated to an annular gas channel which is internally and independently providedwith an auxiliary cavity communicated with the thin injecting pipe; and a gas supplying port of the auxiliary cavity is arranged corresponding to an ignition assembly. According to the single-ring fire burner, due to the fact that the two injecting pipes are used for controlling firepower, the burner can accurately adjust a large fire and a small fire; and a same fire ring is used for supplying gas for the large fire and the small fire of the burner, and by expanding the diameter of the fire ring, the pan bottom can also be heated uniformly during a small fire. Besides, according to the single-ring fire burner, by arranging the auxiliary cavity communicated to the thin injecting pipe, gas is continuously supplied for the ignition assembly at constant amount, and it is avoided that the flameout condition happens to the burner in the small fire adjusting process.

Description

technical field [0001] The invention relates to the technical field of stoves, in particular to a single-ring fire burner. Background technique [0002] Gas stoves refer to kitchen utensils that are heated directly by gaseous fuels such as liquefied petroleum gas (liquid), artificial gas, and natural gas. At present, due to the characteristics of large firepower, most gas stove burners are double-ring fires or three-ring fires. The technical disadvantage of the current double-ring fire and triple-ring fire burners is that more fire rings narrow the air chamber, and air and three-ring fire The secondary mixing of the gas cannot be guaranteed to be uniform, so that the combustion efficiency will not only be reduced, but also carbon monoxide gas harmful to the human body will be generated during combustion; Large amount of gas. In addition, the manufacturing process of double-ring fire or triple-ring fire burners is often complicated, and it is difficult to finely adjust the ...
