Abstract: The invention relates to support legs for bake elements used in microwave ovens. The improved support leg utilizes a conventional wire leg used on bake elements for electric ranges, wherein the leg is formed of wire which is bent to V-shape to provide a bight and legs extending from the bight. Feet are turned outwardly and angularly of the ends of the wire legs, the feet being coined to provide projection welding ridges. A molded ceramic block is slotted to fit into and around the vee and legs of the wire leg, and the two parts are held assembled by welding the feet to the metal sheath of a conventional bake element. The ceramic block is adapted to engage the floor of the microwave oven and is held by the wire leg with sufficient play so that the block may align itself with the oven floor in the event the latter is not level.

Abstract: A means for attaching and securing an apertured mounting bracket to a sheathed electric heating element received therethrough to insure firm mechanical support, preclusion of relative axial motion, reliable electrical grounding, and ease of adaptation to automated assembly, characterized by an initially flangeless sleeve shaped to form a double grip at opposite ends to the heating element with the bracket clamped therebetween.

Abstract: The invention relates to support legs for bake elements used in microwave ovens of the dual-purpose cavity oven type. The improved support leg comprises a threaded stud welded to the sheath of a conventional electric heating element, the stud having a threaded portion projecting from the sheath and adapted to receive an interiorly threaded ceramic sleeve. Ceramic cement is preferably used to insure against disassembly of the sleeve from the stud. The support leg may also be designated as a support standoff since the ceramic sleeve provides electrical clearance between the metal stud and the oven liner bottom to isolate and prevent any metal-to-metal contact.

Abstract: An electrostatic oven or cooking apparatus having a heating structure defining a cavity and conventional thermostatically controlled heating element into which articles are placed is provided with an arrangement to generate an electrical field in a direction substantially perpendicular to the plane of the cooking articles thereby improving the overall efficiency of the cooking process. The improved efficiency of the cooking process results in a reduction in the cooking time relative to conventional ovens. The electrical field generating apparatus in one arrangement includes an electrical field grid element maintained at a reference potential and apparatus for supporting the cooking articles upon being positioned within the heating structure cavity and maintaining the cooking articles at a DC potential with respect to the reference potential. The electrical field grid element and the cooking article support apparatus are spaced apart and adjustable relative to each other.

Abstract: There is disclosed a support leg for a heating element of an electric unit including vertically extending arm members including inwardly extending teeth members which firmly engage the outer surface of the heating element in a manner to prevent subsequent rotation of such support leg.

Abstract: The specification discloses a self-cleaning oven including an outer housing with an oven liner disposed within the housing in a spaced-apart relationship forming cavities between the housing and liner walls. A duct system is provided for directing air from the vicinity of the lower front and rear of the oven to the cavity between the top walls of the housing and liner. A heating element is mounted in a proximate relationship to a smoke eliminator panel mounted on the top liner wall. Smoke and gases emanating from the oven pass through apertures formed in the smoke eliminator panel to a vent tube. The vent tube discharges gases from the smoke eliminator panel into a discharge duct above the oven liner. A diluter tube encompassing the vent tube allows air to pass from the cavity between the top walls of the oven liner and the housing into the discharge duct. The air dilutes the smoke and gases from the oven liner, and the diluted smoke and gases are then exhausted from apertures in the front of the oven.
