Burner cap of household gas stove and combustor provided with same

Abstract

The invention discloses a burner cap of a household gas stove. The burner cap of the household gas stove comprises a burner cap body and an upper cover arranged at the top of the burner cap body. The burner cap is characterized in that the burner cap body is provided with an inner ring wall and an outer ring wall, a center through hole is formed in the center of the inner ring wall, an annular channel is formed between the inner ring wall and the outer ring wall, a through hole is formed in the bottom of the annular channel, and the upper cover is of a sheet structure densely provided with meshes. The invention further discloses a combustor provided with the burner cap of the household gas stove, the burner cap is arranged on a gas mixing chamber, the center through hole is communicated with an inner ring gas mixing cavity, and the through hole in the bottom of the annular channel is communicated with a middle ring gas mixing cavity. The burner cap of the household gas stove has the advantages that by the adoption of the burner cap, a middle ring needs little secondary air, an inner ring achieves fully premixed atmospheric combustion, the temperature of burning flame reaches about 1000 DEG C, the flame is directly injected, combustion is centralized, the secondary air takes little heat away, and therefore the heat efficiency is good; on the premise of ensuring the heat efficiency, little secondary air is needed, and the diameter of the combustor can be small relatively.

Description

technical field [0001] The invention relates to a burner for a gas cooker, in particular to a fire cover for a domestic gas cooker and a burner using the fire cover. Background technique [0002] At present, many domestic gas stove burners use three-ring fire burners. The common three-ring fire burners include a burner base, an inner ring ejector tube, and a middle ring ejector. The burner base has an inner ring channel, a middle ring channel and an outer ring channel, the inner ring channel communicates with the inner ring injector tube, the middle ring channel communicates with the middle ring injector tube, and the outer ring channel communicates with the outer ring channel The injection pipe is connected, and the gas mixing chamber is installed on the burner base. The gas mixing chamber has an inner ring gas mixing chamber, a middle ring gas mixing chamber and an outer ring gas mixing chamber. The air cavity is connected with the middle ring channel, and the outer ring ...

Problems solved by technology

In addition, the fire hole of the central fire cover of the combined three-ring fire burner is set on the side wall of the central fire cover, and there is no fire hole on the top of the central fire cover, so when the burner is working, there is only fire around and no fire in the middle. In order to reduce the flue gas, more secondary air is added, so the heat loss taken away will increase, resulting in a decrease in the thermal efficiency of the burner
