Abstract
A gas burner unit for a cooktop includes a spreader having a first side with a plurality of gas outlets and a second side opposite the first side and defining a portion of a fluid path. The spreader further defines a venturi in fluid communication with the gas outlets and extending away from the second side. The gas burner unit further includes an orifice holder having a protrusion defining an upwardly directed primary air inlet therethrough. The upwardly directed primary air inlet is in fluid communication with the fluid path associated with the spreader on a first end thereof and with the venturi on a second end thereof opposite the first end.

A gas burner unit for a cooktop, comprising:
- a spreader having a first side with a plurality of gas outlets and a second side opposite the first side and defining a portion of a fluid path, the spreader further defining a venturi in fluid communication with the gas outlets and extending away from the second side;
- and
- an orifice holder having a protrusion defining an upwardly directed primary air inlet therethrough, wherein the upwardly directed primary air inlet is in fluid communication with the fluid path associated with the spreader on a first end thereof and with the venturi on a second end thereof opposite the first end.
A cooktop having at least one gas burner unit, comprising:
- a primary surface defining an opening;
- a gas burner unit including a spreader having a first side with a plurality of gas outlets and a second side opposite the first side and spaced from the primary surface to define a fluid path therebetween, the spreader further defining a venturi extending through the opening and in communication with the gas outlets and extending away from the second side;
- and
- an upwardly directed primary air inlet extending through the primary surface in fluid communication with the fluid path on a first end thereof and with the venturi on a second end thereof opposite the first end, wherein the first end is positioned between the primary surface and the second side of the spreader.
A cooktop, comprising:
- a primary surface defining an opening;
- a gas burner unit including:
- a spreader having a side facing the primary surface;
- and
- an orifice holder mounted with the cooktop on an interior thereof opposite the primary surface, the orifice holder supporting the spreader with the second side thereof spaced apart from the primary surface and defining a protrusion with an upwardly directed primary air inlet therethrough, a first end thereof positioned between the primary surface and the side of the spreader and second end thereof positioned with and open to the interior of the cooktop.
