Upper air inlet type burner for gas stove

Abstract

An upper air inlet type burner for a gas stove comprises a base, a gas mixing chamber, an outer ring fire cover and an inner ring fire cover. The base is provided with a cavity with an upward opening, the gas mixing chamber is arranged above the base and provided with an annular cavity, and the inner ring fire cover and the outer ring fire cover are arranged on the gas mixing chamber and located on the inner side and the outer side of the annular cavity respectively. The upper air inlet type burner is characterized in that the cavity is isolated from the annular cavity, the side portion of the gas mixing chamber is provided with a primary air hole and a secondary air hole, the primary air hole is communicated with the cavity to form a primary air channel, and the secondary air hole is communicated with the annular cavity to form a secondary air channel. The upper air inlet type burner has the advantages that due to the fact that the cavity of the base is isolated from the annular cavity of the gas mixing chamber, and the primary air hole is formed in the side portion of the gas mixing chamber, primary air supplement can be carried out without arranging a gap between the gas mixing chamber and the base, a panel screw can be hidden below the gas mixing chamber, and the structure of the burner can be simple; in addition, secondary air can be supplemented to the inner ring fire cover through the annular cavity via the secondary air hole, and therefore the inner ring fire combustion efficiency can be improved.

Description

technical field [0001] The invention relates to a burner, in particular to an upward air-intake burner for a gas stove. Background technique [0002] At present, many gas cookers have begun to use fully upward air-intake burners. Since the complete upward air-intake burners burn, the primary and secondary air required for combustion come from the upper part of the cooker panel, so the chassis of the gas cooker It can be fully sealed. Compared with the traditional bottom air intake structure burner, the completely upward air intake burner is not only safer to use, but also can well solve the problem of stove flameout caused by opening and closing the cabinet door. However, the traditional completely upward air-intake burner is realized through the gap between the air-mixing chamber and the base when the primary air is supplemented. The problem caused by this is that there is a gap between the air-mixing chamber and the base. After the mounting screws are installed, the mount...

AI Technical Summary

Problems solved by technology

It can be seen that the above-mentioned two types of burners with complete upward air intake are supplemented with primary air through the gap between the lower seat and the burner seat and the gap between the upper seat and the lower seat respectively, and further improvement is needed in structure
