Abstract
A burner assembly for a cooktop comprises a spreader comprising (i) a central portion through which an axis extends, the central portion with a bottom surface, (ii) a plurality of apertures through the spreader, the plurality of apertures disposed further away from the axis than the central portion, and (iii) a ridge projecting from the bottom surface, the ridge disposed further from the axis than the central portion but closer to the axis than the plurality of apertures.
Claims21
A burner assembly for a cooktop comprising:
- a spreader comprising (i) a central portion through which an axis extends, the central portion having a bottom surface, (ii) a plurality of apertures through the spreader, the plurality of apertures disposed further away from the axis than the central portion, (iii) a ridge projecting from the bottom surface, the ridge disposed further from the axis than the central portion but closer to the axis than the plurality of apertures, and (iv) an outer portion that includes a lateral edge that defines an outermost perimeter of the spreader relative to the axis;
- and
- a burner cap disposed over the spreader, the burner cap comprising an outer portion comprising a flange that surrounds the lateral edge of the spreader.
A burner assembly for a cooktop comprising:
- a base comprising (i) a tubular wall defining a passageway through which an axis extends, the tubular wall having a first end defining an inlet into the passageway and a second end defining an outlet of the passageway, (ii) a lateral wall extending laterally outward from the tubular wall, and (iii) an outer wall extending upward from the lateral wall and forming a perimeter around the lateral wall, the outer wall is more elevated from the lateral wall than the second end of the tubular wall;
- a spreader disposed above the tubular wall and the lateral wall of the base, the spreader comprising (i) a central portion through which the axis extends, the central portion disposed above the outlet of the passageway of the base, (ii) an outer portion surrounding the central portion, the outer portion terminating in an edge that defines a lateral perimeter of the spreader away from the axis, with the outer wall of the base surrounding the edge of the outer portion of the spreader, and (iii) a plurality of apertures through the spreader at the outer portion;
- and
- a perforated sheet disposed between the base and the spreader, the perforated sheet comprising (i) a central portion through which the axis extends, the central portion disposed between the central portion of the spreader and the tubular wall of the base, (ii) an outer portion further away from the axis than the central portion, the outer portion disposed between the lateral wall of the base and the outer portion of the spreader, the outer portion terminating in an edge, with the outer wall of the base surrounding the edge of the outer portion of the perforated sheet, and (iii) a plurality of apertures through the perforated sheet.
A burner assembly comprising:
- an outlet of a passageway;
- a spreader comprising a plurality of apertures;
- and
- a perforated sheet disposed between the outlet of the passageway and the spreader, the perforated sheet comprising a plurality of apertures, wherein the perforated sheet is disposed over the outlet of the passageway;
- wherein, the burner assembly is configured to direct a mixture of air and gaseous fuel exiting the outlet of the passageway through the plurality of apertures of the perforated sheet and then through the plurality of apertures of the spreader.
