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 and an inner ring fire cover, wherein the base is provided with a center cavity and an annular cavity arranged on the periphery of the center cavity in a surrounding mode; the top of the center cavity and the top of the annular cavity are both open; the inner ring fire cover and the outer ring fire cover are arranged in the center cavity and the annular cavity respectively in a covering mode to form an inner ring gas mixing cavity and an outer ring gas mixing cavity respectively; the outer ring fire cover comprises a fire cover body; the fire cover body comprises a top wall, an inner ring wall and an outer ring wall; the top wall inclines frominside to outside in the circumferential direction; outer ring fire holes are arranged in the top wall in the circumferential direction to form a flame zone; a fire transferring groove extending up and down is arranged in the upper end of the inner ring wall of the outer ring fire cover; the fire transferring groove is communicated with the outer ring gas mixing cavity; and the upper end of the fire transferring groove is adjacent to the flame zone. According to the complete upper air inlet type burner, the lower end of the fire transferring groove is close to the inner ring fire cover, the upper end of the fire transferring groove is close to the flame zone on the outer ring fire cover, and therefore the fire transferring success rate is increased.

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
