Abstract
An electric heating element for the bottom of a cooking oven. The heating element has a unique shape or pattern in plan view that includes two narrow loops or arms extending toward the rear corners of the oven and two wider loops or arms extending toward the front corners of the oven with the narrow loops joined to the wider loops by concave side portions and the two wider loops joined in the front by a concave portion. The extremities of the four loops are closely spaced from the rear wall and two walls of the oven. This shape and size creates more uniform heating throughout the oven cavity than conventional heating elements of different shapes or patterns.
