Gas burner

Abstract

The invention relates to a fuel gas burner, which comprises a fire cover, a flame projector, a base and a gas feeder, wherein said flame projector has central fire ring, inner fire ring, and outer fire ring; one central flame mixing chamber is inside the central fire ring, while it has central fuel gas mixing tube; there are at least three uniform distributed external fuel gas mixing chambers between the inner and outer fire rings; the middle of each external fuel gas mixing chamber is arranged with external fuel gas mixing tube; the base has central nozzle chamber relative to the central fuel gas mixing tube, and the external nozzle chamber relative to the external fuel gas mixing tube; the gas feeder is arranged with the central nozzle relative to the central nozzle chamber and the external nozzle relative to the external nozzle chamber. The invention has simple structure, uniform flame, and large middle fire, while it can use three rings of fire at the same time, and independently use the central fire.

Description

Technical field: [0001] The invention relates to a cooker, in particular to a gas burner. Background technique: [0002] In the prior art, the gas burner disclosed in Chinese patent ZL03241583.4 includes a fire cover, a fire injection device, a base and an air intake device, and the fire injection device has a central fire ring, an inner fire ring and an outer fire ring; wherein, the center A central gas mixing chamber is formed in the fire ring, and a central gas mixing pipe is arranged in it. Two symmetrically distributed peripheral gas mixing chambers are formed between the inner fire ring and the outer fire ring. Each peripheral gas mixing chamber is in the There is a peripheral gas mixing pipe on one side, and besides a central nozzle chamber corresponding to the central gas mixing pipe and two peripheral nozzle chambers corresponding to the peripheral gas mixing pipe, there is also a separate central primary air channel on the base , the air intake device is provided ...

AI Technical Summary

Problems solved by technology

The disadvantages of this burner are: 1. Since there are only two peripheral gas mixing chambers, and the peripheral gas mixing tubes in each peripheral gas mixing chamber are set on one side, not only the supply of gas required for peripheral combustion is not sufficient Stable, and it will inevitably cause the mixed gas to flow unevenly in the mixing chamber, resulting in extremely uneven flames and yellow flames; It also brings a lot of inconvenience. At the same time, because the central primary air passage is set on the base together with the two peripheral nozzle chambers, the secondary air inlet area becomes smaller, resulting in insufficient intermediate firepower.
