Combustor capable of adjusting air door at mixed gas outlet and acting method thereof

Abstract

The invention provides a combustor capable of adjusting an air door at a mixed gas outlet and an acting method thereof. The combustor comprises a furnace end, a gas distribution disc and a fire cover which are stacked from bottom to top, the fire cover comprises an inner ring fire cover and an outer ring fire cover which are in inner and outer ring sleeving, and the gas distribution disc comprises an inner ring gas disc and an outer ring gas disc which are in inner and outer ring sleeving. The inner ring fire cover and the inner ring gas disc are buckled to form an inner ring gas mixing chamber, the outer ring fire cover and the outer ring gas disc are buckled to form an outer ring gas mixing chamber, a plurality of gas inlet holes are formed in the side of the furnace end, an outer ring gas mixture outlet is formed in the bottom wall of the outer ring gas disc, one gas inlet hole is connected with the outer ring gas mixture outlet through an outer ring injection pipe, an inner ring gas mixture outlet is formed in the bottom of the inner ring gas disc, the other gas inlet hole is connected with the inner ring gas mixture outlet through an inner ring injection pipe, and an adjusting assembly used for changing the ventilation sectional area is arranged at the outer ring gas mixture outlet and / or the inner ring gas mixture outlet. An air door adjusting structure is arranged at the gas mixture outlet, visual adjustment is achieved, and operation is easy.

Description

technical field [0001] The invention belongs to the technical field of kitchen stoves, in particular to a burner for adjusting a damper at the outlet of a mixed gas and its functioning method. 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. According to the source of gas, gas stoves are mainly divided into liquefied gas stoves, gas stoves, and natural gas stoves. According to the focal point, it can be divided into single focal point, double focal point and multiple focal point. [0003] The desktop cooker is mainly composed of a burner (burner head, inner and outer fire cover), valve body (including nozzle, damper plate, conical spring), shell (which can be a split shell-panel, rear plate and left and right side plates) It can also be composed of an integral stretch shell), a stove frame, a knob, a liquid pan, a stove foot, an air intake ...

AI Technical Summary

Problems solved by technology

[0004] The burner that adjusts the damper at the outlet of the mixed gas is used to adjust the amount of primary air intake to adjust the combustion state of the burner. At present, all adjustment methods are adjusted at the end of gas injection and primary air intake. This adjustment requires It is very inconvenient to remove the bottom shell from the stove and then adjust it, especially for integrated stoves, because the stove is integrated with the functional cabinet below, the damper adjustment device is complicated, the cost is high and the adjustment is extremely inconvenient
