A gas cooker burner with stable inner ring flame

Abstract

A gas cooker combustor with stable inner ring flames comprises a base, a gas mixing chamber arranged on the base and an inner ring burner cap arranged in the gas mixing chamber. Fire holes are formed in the inner ring burner cap, and the base and the gas mixing chamber are provided with a vertical through inner ring gas channel. The gas cooker combustor is characterized in that an annular cavity communicated with the vertical through inner ring gas channel is formed in the inner ring burner cap, the center of the bottom of the annular cavity is communicated with the inner ring gas channel, and the fire holes are formed in the top face of the inner ring burner cap. The gas cooker combustor has the advantages that the annular cavity is formed in the burner cap body, and the bottom center of the annular cavity is communicated with the inner ring gas channel, so that after gas enters the annular cavity of the inner ring burner cap through the inner ring gas channel, the gas speed is lowered, inner ring flames are stably sprayed out of the fire holes, and therefore the bottom of a pan can be conveniently and evenly heated; in addition, due to the fact that the fire holes are formed in the top face of the inner ring burner cap, the inner ring flames can be sprayed out almost vertically, and the bottom of the pan can be more evenly heated.

Description

technical field [0001] The invention relates to a burner for a gas cooker, in particular to a burner for a gas cooker with a stable inner ring flame. Background technique [0002] The burners of existing gas cookers are generally provided with an outer ring fire cover and an inner ring fire cover, wherein the inner ring fire cover is generally a cylinder, and a plurality of circular fire holes are opened along the circumferential direction on the side wall of the cylinder. The angle between the inclination angle of the fire hole and the horizontal plane is generally 20-40 degrees. When this kind of burner is working, the flame in the inner ring obviously sprays out obliquely, forming a ring-shaped heating ring when it contacts the bottom of the pot, which leads to uneven heating of the bottom of the pot. In addition, the inner ring gas of this kind of burner is directly sprayed from the fire hole of the inner ring fire cover without buffering, so the air velocity at the fir...

Problems solved by technology

[0003] In addition, the ignition needle and thermocouple of the existing traditional burner are exposed outside after installation. If there is wind blowing in from the range hood or the window, the gas is easily affected by the wind during ignition and often causes difficulty in ignition. There are also hidden dangers of automatic flameout and fire protection failure
