Stove burner

Abstract

The invention relates to a stove burner. The stove burner comprises an outer ring gas mixing chamber, wherein the outer ring gas mixing chamber comprises an inner ring wall face and an outer ring wallface which are in a ring shape and concentrically arranged at an interval, and a bottom wall connected with the inner ring wall face and the outer ring wall face, an outer ring fire cap covers abovethe inner ring wall face and the outer ring wall face, and radial main fire grooves are formed in the circumferential direction of the outer ring wall face at intervals. The stove burner is characterized in that a regulation ring which keeps an adjoining state with the inner side of the outer ring wall face is arranged in the outer ring gas mixing chamber, and the periphery of the regulation ringis provided with at least two protruded parts protruded out in the radial direction so as to stretch into the main fire grooves and then change the cross area of effective airstream channels in the main fire grooves. Compared with the prior art, the stove burner has the advantage that by arranging the regulation ring which can move relatively to the main fire grooves so as to regulate the open area of the main fire grooves in the outer ring gas mixing chamber, the velocity of mixed gas jetted to the main fire grooves is regulated.

Description

technical field [0001] The invention relates to a burner, in particular to a cooker burner with adjustable flame holes. Background technique [0002] Generally, according to a method of burning gaseous fuel in a gas boiler, such as a premix burner, gas and air are premixed at a mixing ratio optimum for combustion, and then supplied to the surface of a fire hole for combustion. That is, after the mixed gas and air injected from the nozzle of the gas injection port flow into the mixing chamber, the mixed gas is supplied to the combustion chamber through the flame hole, and burns in the combustion chamber. A typical burner in the related art includes a gas valve that adjusts the gas pressure supplied to the burner, a nozzle that injects the gas supplied through the gas valve, and a mixed gas inlet through which the gas injected from the nozzle passes. Mixed and supplied, the inner space of the burner, the mixed gas supplied through the mixed gas flow inlet is supplied to this ...

[0003] For this reason, the applicant provides a Chinese utility model patent "Burner with Adjustable Flame Hole" whose patent number is ZL201720766832.3 (notification number is CN206958909U), which discloses such a burner with adjustable fire hole, including Shooting parts, gas mixing seat and fire cover, characterized in that the fire cover has a circle of mounting holes, and a spherical movable body is provided on the described gas mixing seat corresponding to each mounting hole, and the movable body is limited to the aforementioned There is a radially hollow fire outlet in the installation hole, the inlet end of the fire outlet communicates with the air mixing chamber of the air mixing seat, and the air outlet end forms the fire hole, and the air mixing seat corresponds to each Each movable body is provided with a stepping motor, and the output shaft of the stepping motor is connected with the outer wall of the movable body and can drive the rotating inside and outside of the movable body; At a predetermined speed, the phenomenon of flame tempering will occur inside the fire hole, and further improvement is needed. In addition, the stepper motor drives the movable body to rotate relative to the fire cover, and the firepower methods are various; but the combustion of the fire cover The process is a high temperature zone, how the stepper motor can avoid the high temperature zone, and how to form an insulating belt between the stepper motor and the fire cover are issues that need further consideration
