Abstract
In a device for raising and lowering a burner element of an electric range, cookware is supported upon a plurality of rigid posts and the burner element is raised and lowered in a plane parallel to the plane of the bottom surface of the cookware. This allows the user to obtain radiant heat transfer for more even cooking. In addition, lowering the burner allows the cookware to cool quickly without removing it from the range, unlike traditional electric ranges where the cookware rests directly upon the burner element and must be removed from the range to cool.
