Problems solved by technology

These and other types of airflow disturbances can affect the stability of the flame at the burner port to the point of causing the flame to go out
Flame extinguishment due to airflow disturbances is inconvenient, at least because the burner must be re-ignited

Embodiment Construction

[0016] Referring to the drawings, there is shown an embodiment of a burner assembly of the present invention, generally indicated at 10, in which a combustible gas may be combusted. The burner assembly 10 includes a burner body or burner head, generally indicated at 20 , and a stabilization chamber, generally indicated at 40 . The embodiment of the combustor assembly shown in the figures also includes a cover, generally indicated at 70 . The burner body 20 includes a generally frusto-conical outer surface 22 and a generally cylindrical first inner surface 24 . The outer surface 22 and the inner surface 24 surround on opposite sides an annular structure generally designated by the reference numeral 30 . Approximately centrally with respect to the boundary of the annular structure 30 there is provided an annular projection generally designated by reference numeral 32 comprising an opening 26 approximately centrally located therein. The opening 26 is in gas flow communication w...

Abstract

The present invention concerns a burner assembly that includes a burner body having a combustible gas chamber from which a combustible gas is distributed to a plurality of burner ports at which the combustible gas can be combusted and a stability chamber in gas-flow communication with the combustible gas chamber for maintaining the combustion of the combustible gas in the stability chamber whenever the combustion of the combustible gas at the plurality of burner ports is disturbed, whereby the combustion of the combustible gas at the plurality of the burner ports may be resumed upon the cessation of the disturbance. The burner assembly can also include a burner cap for closing off the top of the burner body so as to substantially preclude the escape of the combustible gas from the combustible gas chamber, the stability gas chamber and the burner ports at the top of the burner body.

Description

technical field [0001] The present invention relates to a burner for burning a combustible gas; in particular, the present invention relates to a burner of the type used in various cooking appliances. Background technique [0002] Gas burners, such as gas surface burners, such as those used with domestic gas ranges, typically include a burner body or burner head that includes a plurality of burner ports ( burner port), through which the combustible gas is distributed to the outside of the burner body. A burner cap may be provided on top of the burner body in order to close the outlet of the interior of the burner body to the combustible gas. Typically, a mixing duct directs a mixture of gaseous fuel and air as a combustible gas into the burner body. The gas mixture may be confined in a combustible plenum within the burner body closed by the burner cover. Combustible gas usually passes through these burners from the combustible chamber and is ignited by an igniter to burn....
