Abstract
An electromagnetic interference (EMI) shield for gas cooktops is disclosed herein. The EMI shield protects electromagnetic fields output by a high voltage spark ignition system from interfering with sensitive low voltage controls for the cooktop. Accordingly, the low voltage controls and similar elements are mounted on one side of the EMI shield and the high voltage spark ignition system, burners, and similar elements are mounted on another side of the EMI shield. In order to connect elements on each side of the EMI shield as may be necessary (e.g., electrical wires and gas tubing), the EMI shield can have a plurality of small openings. The EMI shield may also provide a mount for controls and/or a user interface for displaying information and controlling the cooktop.
