Complete upper air inlet type burner

Abstract

The invention relates to a complete upper air inlet type burner. The complete upper air inlet type burner comprises a base, an outer ring fire cover, an inner ring fire cover and outer ring injectionpipes, wherein the base is provided with a center cavity and an annular cavity; the number of the outer ring injection pipes is two; each outer ring injection pipe is communicated with an outer ring gas mixing cavity; the two outer ring injection pipes are transversely and oppositely arranged; gas inlets of the two outer ring injection pipes are staggered; and an annular gap is reserved between the annular cavity and the center cavity, an annular cover body with the center cavity as the center is arranged in the annular gap, the two outer ring injection pipes are arranged at the bottom of thecover body respectively, and therefore secondary air channels defined by the bottom face of the bottom wall of the annular cavity and the upper face of the cover body are arranged in the two sides ofthe bottom of the base respectively. Compared with the prior art, the injection efficiency can be improved, the auxiliary ignition effect can be achieved, primary air and secondary air can be shuntedthrough the arrangement of the cover body, a combusted gas mixture is prevented from being mixed into all the injection pipes, and therefore normal combustion of the burner is guaranteed.

Description

technical field [0001] The invention relates to the field of gas stoves, in particular to a completely upward air-flow burner. Background technique [0002] Due to the limitation of its own structure, the traditional upward-inlet gas burner generally has the problem of low injection efficiency. For example, the Chinese invention patent with the application number 201711370764.X (publication number CN108036320A) discloses a top-mounted burner, which includes a fire cover, a middle plate and a base from top to bottom, and the middle plate and the base are installed and matched to form a small burner. Fire ejection pipe and main fire ejection pipe, there are also small fire ejection pipe and main fire ejection pipe in the middle plate, the outlet end of the small fire ejection pipe is connected with the small fire ejection pipe, and the gas outlet end of the main fire ejection pipe is connected with the main fire ejection pipe The other end of the small fire injection pipe and...

AI Technical Summary

Problems solved by technology

In this patent, due to the structural limitation of the combustion chamber, the length of the main fire ejector tube is relatively short, so its ejection distance is short and its ejection force is affected

In addition, some upward air-intake burners on the market supplement the air required for combustion by opening holes in the panel. Soup or cooking sundries can easily enter the shell of the cooker through the panel, which is inconvenient to clean
