AI Technical Summary
Technical Problem
Existing stacked burners have limited reliability in igniting the first burner ports and exhibit undesired flame quality, including flame lifting during ignition.
Method used
A burner design with a base and spreader configuration that includes channels for fuel distribution and ignition ports, where the spreader's lower surface is interrupted by channels and partially enclosed by the base's upper surface to define flame and ignition ports, allowing for reliable ignition and controlled flame output.
Benefits of technology
The design ensures faster and more reliable ignition of the first flame ports, maintains acceptable flame length, and reduces flame lifting, providing consistent and efficient cooking performance.

Abstract
A burner for a cooktop includes a base defining a first side wall having an annular main portion and an ignition portion extending inwardly with respect to the annular main portion, the first side wall including at least one ignition channel extending from an interior thereof to an exterior within the ignition portion, an upper surface of the base extending inwardly from the side wall. The burner further includes a spreader removably disposed over the base. The spreader defines a lower portion enclosing a first distribution chamber. The lower portion defines a first set of flame ports from the first distribution chamber to an exterior of the burner and a continuous planar portion extending over the ignition portion of the first side wall to at least partially enclose at least one respective ignition port from the first distribution chamber to the exterior within the ignition portion.
