Abstract
A cooktop appliance includes a top panel. A gas burner assembly includes an annular burner body positioned on the top panel at a top surface of the top panel. The annular burner body defines a central combustion zone. The annular burner body also defines a plurality of flame ports at the central combustion zone. Gaseous fuel is flowable from a fuel chamber within the annular burner body into the central combustion zone through the plurality of flame ports. The gas burner assembly further includes features for direction the gaseous fuel into the fuel chamber of the annular burner body. The annular burner body is open at the central combustion zone such that the top panel is exposed through the annular burner body at the central combustion zone.
Claims20
A cooktop appliance, comprising:
- a top panel having a projection that extends upwardly from a top surface of the top panel;
- and
- a gas burner assembly positioned at the top panel, the gas burner assembly comprising an annular burner body positioned on the top panel at the top surface of the top panel, the annular burner body defining a central combustion zone, the annular burner body also defining a plurality of flame ports at the central combustion zone, gaseous fuel flowable from a fuel chamber within the annular burner body into the central combustion zone through the plurality of flame ports,
- wherein the central combustion zone is positioned concentrically with the projection of the top panel, and the annular burner body is open at the central combustion zone such that the projection is exposed through the annular burner body at the central combustion zone, and
- wherein the projection extends upwardly into the central combustion zone.
A cooktop appliance, comprising:
- a top panel having a projection that extends upwardly from a top surface of the top panel;
- and
- a gas burner assembly positioned at the top panel, the gas burner assembly comprising an annular burner body positioned on the top panel at the top surface of the top panel, the annular burner body defining a central combustion zone, the annular burner body also defining a plurality of flame ports at the central combustion zone, the plurality of flame ports positioned proximate an inner side wall of the annular burner body, gaseous fuel flowable from a fuel chamber within the annular burner body into the central combustion zone through the plurality of flame ports, a bottom surface of the annular burner body spaced from the top surface of the top panel such that air is flowable under the annular burner body into the central combustion zone,
- wherein a distal end portion of the projection is positioned above the bottom surface of the annular burner body, the projection is spaced from the inner side wall of the annular burner body by an annular gap, and the air is flowable under the annular burner body and through the annular gap into the central combustion zone,
- wherein the annular burner body is open at the central combustion zone such that the projection is exposed through the annular burner body at the central combustion zone, and
- wherein the projection extends upwardly into the central combustion zone.
