cooktop burner

Abstract

The invention discloses a cooker burner, which comprises an inner ring fire cover and an inner ring gas passage, and also includes at least two mutually independent outer ring fire covers and outer ring gas passages corresponding to the number of the outer ring fire cover. The outlets of the gas channels are respectively connected to the corresponding outer ring fire covers, one of the outer ring gas channels is a ring structure concentrically arranged with the inner ring gas channel, and the rest of the outer ring gas channels are offset to one side of the inner ring gas channel , and are respectively arranged adjacent to the inner ring gas channel, and the outer ring fire cover is not provided with a fire hole at the outlet position of the outer ring gas channel corresponding to the offset setting. The cooker burner is provided with at least three gas channels that supply gas independently of each other, and one outer ring gas channel is arranged concentrically with the inner ring gas channel, and the other outer ring gas channels are offset to one side of the inner ring gas channel. There is no fire hole at the exit position of the outer ring fire cover corresponding to the offset set outer ring gas channel, which solves the problem of poor uniformity of the gas relative to the fire cover fire hole.

Description

technical field [0001] The invention relates to a cooker burner. Background technique [0002] At present, some cooker burners have two fire rings, the inner ring and the outer ring. This technology is relatively mature, see patent CN201652366 U, but it needs to achieve higher thermal efficiency in a limited space, and improve the heat intensity and uniformity of the bottom of the heating pot. have reached the bottleneck. Another part of the stove burner can provide a three-ring fire, which is usually a fake three-ring without three channels of independent gas supply, so it cannot realize independent adjustment of the three-ring fire, the mixing uniformity will become poor, and the gas will not be fully burned. It also limits the improvement of burner performance; some burners can provide three independent gas channels, which are distributed to the fire cover through the gas mixing chamber, which will cause the diameter of the gas mixing chamber to be too large, and the inn...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a cooker burner to overcome the defects of large gas mixing chamber and difficulty in supplementing secondary air in the multi-ring fire cooker burner in the prior art.
