Burner of gas cooker

Abstract

The invention discloses a burner of a gas cooker. The burner comprises a burner head, and an outer ring gas groove, a central gas groove, an outer ring gas ejection pipe which communicates with the outer ring gas groove, and a central gas ejection pipe which communicates with the central gas groove are arranged on the burner head; a fire cover seat is arranged at the upper end of the burner head; an outer ring fire cover which communicates with the outer ring gas groove and a central fire cover which communicates with the central gas groove are arranged at the upper end of the fire cover seat; an annular groove which communicates with the outer ring gas groove is formed in the lower end of the outer ring fire cover; a plurality of bosses are arrayed on the circumference of the upper end of the outer ring fire cover; grooves are formed between the adjacent bosses; a plurality of first strip-shaped fire grooves which penetrate through the space in the direction from the ring outer sides to ring core sides of the bosses are formed in the upper surfaces of the bosses; a plurality of second strip-shaped fire grooves which penetrate through the space in the direction from the ring outer sides to ring core sides of the grooves are formed in the upper surfaces of the grooves; and the bottoms of the first strip-shaped fire grooves and the bottoms of the second first strip-shaped fire grooves communicate with the annular groove. According to the burner, the three-dimensional supplementation capability of secondary air is high, and stable combustion is facilitated.

Description

[0001] [technical field] [0002] The invention relates to a burner for a gas stove. [0003] [Background technique] [0004] At present, the existing gas cooker burners are limited by the shape, size and processing technology of the fire cover, and dense fire holes or fire grooves are usually arranged on the same plane of the fire cover, which is not conducive to the three-dimensional supplement of secondary air. In addition, the secondary air replenishment of existing gas cookers depends entirely on the flow direction of the secondary air itself. When the burner is provided with fire holes or fire grooves with different heat intensities, secondary air with low heat intensity will appear. Wasteful and insufficient supplementary secondary air at places with high thermal intensity, so that the gas cannot be completely burned during the combustion process of the burner, resulting in low thermal efficiency and excessive generation of harmful gases. [0005] Therefore, how to over...

Problems solved by technology

[0004] At present, the existing gas cooker burners are limited by the shape, size and processing technology of the fire cover, and dense fire holes or fire grooves are mostly set on the same plane of the fire cover, which is not conducive to the three-dimensional supplement of secondary air

In addition, the secondary air replenishment of existing gas cookers depends entirely on the flow direction of the secondary air itself. When the burner is provided with fire holes or fire grooves with different heat intensities, secondary air with low heat intensity will appear. Wasteful and insufficient supplementary secondary air at places with high heat intensity, so that the gas cannot be completely burned during the combustion process of the burner, resulting in low thermal efficiency and excessive generation of harmful gases
