Burner for gas stove

Abstract

The invention relates to a burner for a gas stove. The burner for the gas stove comprises a base, an inner ring burner cap and an outer ring burner cap, wherein the inner ring burner cap and the outerring burner cap are connected to the base. The top face inner wall and annular inner wall of the inner ring burner cap form a central gas mixing chamber, and an inner ring burner port communicating with the central gas mixing chamber is formed in the annular inner wall of the inner ring burner cap. The top face inner wall and annular inner wall of the outer ring burner cap form an outer ring gasmixing chamber, and a plurality of outer ring burner ports are formed in the annular peripheral wall of the outer ring burner cap. The burner for the gas stove is characterized in that at least one ejector pipe is arranged on the outer circumferential wall of the central gas mixing chamber, and nozzles matched with the gas inlet ends of the ejector pipes are arranged on the circumferential wall ofthe outer ring gas mixing chamber correspondingly. Compared with the prior art, the burner for the gas stove has the advantages that fuel gas in the outer ring gas mixing chamber is ejected to the central gas mixing chamber through at least two ejector pipes, the combustion condition can be changed through the ejection amount of the ejector pipes, and combustion homogeneity is guaranteed; and moreover, a plurality of strands of gas jet flow are arranged and can be mixed with primary air more sufficiently, ejection capacity is enhanced, and thus combustion efficiency is improved.

Description

technical field [0001] The invention relates to the field of gas stoves, in particular to a burner for a gas stove. Background technique [0002] The injection structure of the existing burner can be divided into vertical injection structure and horizontal injection structure, as well as upper air inlet burner and lower air inlet burner, but no matter what type of burner it is, it is a nozzle Corresponds to a Venturi tube. And most of the burners currently have only one nozzle and a corresponding outer Venturi tube to bear the air supply load of the entire outer ring fire, and one nozzle and a corresponding inner Venturi tube to bear the air supply load of the inner ring fire Therefore, it is difficult to substantially increase the gas volume, especially the required primary air volume, so the heat load is relatively low, and it is difficult to meet the needs of Chinese families, especially Chinese families, for stir-frying, especially for upward air combustion Compared wi...

AI Technical Summary

Problems solved by technology

And most of the burners currently have only one nozzle and a corresponding outer Venturi tube to bear the air supply load of the entire outer ring fire, and one nozzle and a corresponding inner Venturi tube to bear the air supply load of the inner ring fire Therefore, it is difficult to substantially increase the gas volume, especially the required primary air volume, so the heat load is relatively low, and it is difficult to meet the needs of Chinese families, especially Chinese families, for stir-frying, especially for upward air combustion For the burner, compared with the down-inlet burner, its deficiency in this point is particularly obvious

Most of the ejectors of the upward-inlet burners are arranged vertically. For the upward-inlet burners with vertical structure ejectors, the ejector tube is limited by the height of the burner. The ejector tube cannot be made long. The capacity does not meet the requirements, resulting in insufficient combustion, low efficiency, yellow fire, etc., and the overall height of the stove becomes higher, which affects the appearance

In addition, when the existing burner is working, the water or soup overflowing from the pot will overflow into the burner and flow into the cooker through the air replenishment channel in the burner, which is not only not conducive to the cleaning of the burner and the cooker, but also It also affects the service life of the burner, such as the "Gas Stove Burner" disclosed by the Chinese Utility Model Patent No. ZL200920061965.6 (the authorized announcement number is CN201448848U) is exactly such a burner
