Abstract: A burner assembly includes a spreader, a burner base, and at least one annular burner cap. The spreader has a bottom and a combustion chamber that is defined by a crenellated wall wherein a plurality of fuel exit portions defines the crenellated wall. The burner base includes a peripheral wall. The at least one annular burner cap is coupled to the peripheral wall of the burner base and is positioned on the crenellated wall.

Abstract: A fuel-burning cooking burner includes a base defining an outer periphery and an inner open area. The burner further includes a cap coupled with the base around the outer periphery thereof and extending over the open area to define a distribution cavity on an interior side of the cap. The cap further defines a convex outer surface extending opposite the distribution cavity and a plurality of outlets extending through the cap from the distribution cavity to the exterior surface. The outlets are distributed over the entire exterior surface.

Abstract: A gas burner having a switchable flame includes a combustion chamber having a bottom and a circumferential crenellated wall with a plurality of fuel exit ports disposed in the circumferential crenellated wall. The fuel exit ports are directed generally inwardly toward the combustion chamber and also upwardly from the bottom of the combustion chamber. The gas burner additionally includes a burner base and a swirl spreader disposed above the burner base which defines a top portion of the circumferential crenellated wall of the combustion chamber. An annular burner cap set includes an inner flame burner cap and a vertical flame burner cap where the inner flame burner cap and the vertical flame burner cap are selectively and alternatively positioned on the circumferential crenellated wall to define an inner flame state and a vertical flame state, respectively, of the fuel exit ports.

Abstract: A burner assembly for a cooktop includes a base portion having one or more vents and an eccentric stem. A cover portion is received on the base portion to define a mixing chamber disposed between the cover portion and the base portion. The cover portion includes a plurality of fuel ports opening inwardly into a centrally disposed combustion chamber. A venturi mixer is received through the eccentric stem and is configured to provide a primary-air and gas mixture to the mixing chamber as supplied from the cooktop. An aperture is disposed through an upper surface of the cooktop and is configured to pivotally receive the eccentric stem of the base portion for pivoting the burner assembly on the cooktop.

Abstract: A gas burner for a cooking appliance includes a body defining perimeter and having a plurality of first groups of respective pluralities of first outlets a plurality of second groups of respective pluralities of second outlets. Each of the first outlets respectively defines a first outlet area, and each of the second outlets defines respective reduced outlet areas that are less than the first outlet area. Further, the first groups and second groups are alternately arranged around the perimeter, and a total number of first outlets is greater than a total number of second outlets.
