A combination gas burner assembly includes a first burner forming a first profile shape and a second burner positioned above the first burner. The second burner forms a second profile shape different from the first profile shape. The first burner and the second burner form a perimeter of the gas burner assembly. The first profile shape overlaps with the second profile shape forming an overlapping portion of the perimeter.

Cooking burner

A cooktop for an appliance includes a cooktop base surface that defines an edge. A cooktop burner is mounted on the cooktop base surface. A support base is rigidly fixed with the cooktop base surface adjacent the edge. A grate is rotatably supported to the support base and is rotatable between a raised position and a lowered position to alternately cover and uncover the cooking burner. A biasing member is coupled to the support base and exerts an upward biasing force on the grate.

Cooktop with hinged burner grates

A cooking appliance includes a cooktop and a burner mounted on the cooktop. At least one coupling member is coupled to the cooktop. A grate, a griddle, or a reversible griddle is selectively coupled to the at least one coupling member and is operable between a raised position and a lowered position when the grate, the griddle, or the reversible griddle, is engaged with the coupling member.

An orifice holder includes a body defining inner wall portions facing each other and spaced apart at a first distance for receiving a portion of a stem of a spreader therebetween. The body further defines a first cup and a second cup, each extending outwardly from opposing sides of the inner wall portions. Each of the first cup and the second cup has a peripheral rim extending around an upper perimeter thereof and open at respective adjacent ends of the inner wall portions to define a fluid path past the peripheral rims, through the respective first and second cups, between the inner wall portions, and into the stem.

Orifice holder

A gas burner for a cooktop includes a spreader extending along a major axis to define an elongated shape. The spreader further defines an underside and includes a first projection and a second projection extending away from the underside. An orifice holder includes a body and a first lobe and a second lobe extending radially outward from the body. The first and second projections are opposingly adjacent to at least one of the first and second lobes. The orifice holder is mutually engageable with the spreader, with the first and second projections opposingly adjacent with at least one of the first and second lobes.

Anti-rotation feature for a burner

A cooking appliance includes a body and a cooktop disposed on the body. A plurality of gas burner assemblies is operably coupled to the cooktop. A first frame member is coupled to a first side of the cooktop and defines at least a portion of a sump defined by the cooktop. A second frame member is coupled to a second side of the cooktop and defines at least a portion of the sump defined by the cooktop. A bracket is coupled to the first and second frame members. The bracket extends along a portion of a perimeter of the cooktop between the first and second frame members. The bracket defines at least a portion of the sump defined by the cooktop.

Cooktop with side frame members

An orifice holder includes a body that defines an inner chamber and inner wall portions. The inner wall portions each have a first width that is defined relative to the upper portion of the body. A first cup extends outwardly from the inner wall portions. A second cup extends outwardly from the inner wall portions and interconnects with the first cup through the inner wall portions. An airflow path is defined to the inner chamber from the first and second cups.

A compact non-rotational mounting feature or mechanism is employed for mounting an orifice holder to a support member below a cooktop of a gas cooking appliance. More specifically, the holder and support member include interengaging polygonal structure, such as a key-shaped anti-rotational peg and hole combination, allowing the holder to be initially mated with the support member in a manner which prevents relative rotation and assuring that the holder is appropriately positioned for proper alignment of various gas burner components, such as an orifice, a gas line, electrode, flame spreader and other burner related structure. Upon exacting the positioning of the holder relative to the support member, the holder to fixed in position by a mechanical fastener.

A heating appliance includes a cooktop having a plurality of burners. A burner box defines a burner position for each burner, each burner position having a plurality of slots. An orifice holder is slidably engaged with the plurality of slots in a linear direction. Opposing flanges extend from a bottom portion of the orifice holder that extend through the plurality of slots to be at least partially secured therein, wherein the opposing flanges are adapted to engage the plurality of slots in only one directional orientation.
