Gas burner for a cooktop

摘要

The present invention refers to a gas burner (16), in particular a gas burner for a cooktop, comprising a plurality of burning portions (40, 42, 44). A gas burner according to the present invention comprises a plurality of burning portions (40, 42, 44) adapted to receive a gas flow from gas supply means (20, 30, 36) that comprise injector means (20) adapted to eject a gas flow diverging along the flow direction (10) to define a spreading angle Y. The gas burner is characterized in that gas-flow adjusting means (24, 25) are provided for modifying said spreading angle Y such that said gas flow is enabled to supply one or more of said plurality of burning portions (40,42, 44) depending on the adjustment of said spreading angle Y.

1. Gas burner comprising a plurality of burning portions adapted to receive a gas flow from gas supply means that comprise an injector means adapted to eject a gas flow diverging along the flow direction to define a spreading angle γ, characterized in that gas-flow adjusting means are provided for modifying said spreading angle γ such that said gas flow is enabled to supply one or more of said plurality of burning portions through at least one of a first chamber and a second chamber coaxial with the first chamber depending on the adjustment of said spreading angle γ; wherein at a first adjustment of said spreading angle γ, said gas flow is enabled to supply through the first chamber and not through the second chamber; wherein at a second adjustment of said spreading angle γ, said gas flow is enabled to supply through the second chamber; wherein said plurality of burning portions are supplied by a single injector means; and wherein said gas-flow adjusting means are formed on said injector means.
