ABSTRACT:
An improved electrical heating element is constructed to increase the amount of electrical wire per unit space available for plug-type convection heating units. The heating element includes a metal frame structure with a plurality of spaced support elements and a plurality of spaced removable cross bars connected thereto. A plurality of ceramic heater support blocks, each of T-shape in plan, with spaced end faces are arranged end to end and have undercut grooves which receive a cross bar and are interposed between the support elements. A continuous electric resistance heating wire has a series of parallel spaced inverted U-shaped wire sections. The wire sections are arranged in groups. Each block has a support boss of reduced width adjacent one end face adapted to extend between the strands of a section of the heating wire. Each block has a pair of spaced bosses adjacent to its other end face which extend laterally outward of the support boss. Each wire section of a group is mounted upon a support boss of each block on one cross bar with the spacer bosses extending between and outward of adjacent sections. The one strands of adjacent sections are transversely interconnected below a row of support blocks mounted on an ajacent cross bar.
