Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
