a stove burner

Abstract

The invention relates to a cooker burner. The burner comprises a fire distributor, a combustion disc, a base and an ignition device. Distributors include outer distributors and central distributors. The combustion disc is equipped with three rings of fire power and three flame-stabilizing grooves. It also has four integral passages, which not only have the largest cross-sectional diameter required for the gas to enter the combustion disc, but also have four fan-shaped secondary air at the bottom of the disc. suction point. To ensure the secondary air replenishment of the inner ring fire and the center fire. The injection pipes connected with the main fire gas pipe and the central fire gas are arranged on two mutually staggered horizontal planes, the air intake is independent and does not interfere with each other, which greatly preserves the kinetic energy of the gas and reduces the resistance of the injection pipes to inhale air. Make the primary air inhale fully, no yellow fire will appear, the flame will not backfire or go off fire, and the combustion will be more complete.

Description

technical field [0001] The invention relates to a device used on a gas stove, in particular to a stove burner. Background technique [0002] At present, most of the burners in the gas stoves sold on the market and used at home have adopted three-ring fire and double-jet gas technology. The gas is ejected by two gas ejectors respectively, and the gas ejected by the two gas ejectors is divided into a central fire, an inner ring fire and an outer ring fire by a combustion disc and a flame distributor, forming a three-ring flame. Although the flame distribution of this type of burner is uniform, the area acting on the bottom of the pot is enlarged, and the combustion efficiency is improved. But there are also the following disadvantages: [0003] 1. If figure 1 , figure 2 As shown in FIG. 2 , there are two structural schematic diagrams of the connection between the existing double ejector and the base. In the figure, the base is a vertical coaxial double cylinder, the oute...

AI Technical Summary

Problems solved by technology

The walls of the air cavity of the combustion disc 2 and the fire cover 3 of the traditional technology are relatively thick, and the space in the air cavity is occupied when the screw is fastened, and the inner diameter cross-sectional area of ​​the air cavity is reduced, causing the gas to go through multiple turns, and the gas pressure is damaged again , especially artificial gas with a fast burning speed is easy to temper, (tempering is a major defect of the burner)

In order to ensure a sufficient diameter of the air cavity, if the size is increased outward, the secondary air passage at the bottom of the combustion pan will inevitably be reduced. Insufficient supplementary secondary air will also cause excessive carbon monoxide in the flue gas

At the same time, it is not conducive to the heat balance of the burner, and will reduce the effective service life of thermocouples, ignition needles and other devices installed between the central fire and the inner ring fire.

Therefore, the cross-sectional diameter of the gas inlet and outlet of the base and the combustion disc in the prior art is small, the resistance is large, the gas is not smooth, and the power is difficult to increase

[0005] 3. There is no flame stabilizing groove in the existing burner, which cannot fully adapt to the combustion speed of various gas sources in my country

Therefore, a flange is added to the lower part of the fire groove of the external firearm, and some fire transmission is slow, and severe deflagration will be caused.

For thinner external firearms, the ignition groove is deeper, and the strength decreases, causing deformation and affecting its free disassembly
