Abstract: A bottom electric heating element for an oven wherein the electric heating element is positioned in a recessed portion in the oven bottom and comprises at least one corrugated ribbon of conductive material partially embedded in an insulating base. A glass panel is positioned over the recessed portion and on a compressible heat resistant gasket. The glass panel is transparent or semi-transparent, high temperature resistant and high impact resistant. A frame extends around the glass panel and fastens it to the oven bottom while partially and resiliently compressing the gasket to support the glass panel.

Abstract: An oven temperature control system for an oven cell having a top heating element with two separate heating conductors in a top portion of the oven cell, a bottom heating element with two separate heating conductors in a bottom portion of the oven cell, and a convection heating element and fan. A control separately controls the on and off operations of each of the heating elements and the convection fan based on a selected mode of cooking operation and a selected temperature for cooking. A plurality of temperature sensors are positioned at different locations in the oven cell and operatively connected to the control. The control determines the selected temperature for cooking to be maintained in the oven cell by averaging selected temperatures sensed by the plurality of temperature sensors in predetermined proportions based on the selected mode of cooking operation.

Abstract: A water spray system for dishwasher with an upper dish rack and a lower dish rack, with each said dish rack being mounted for selective movement forwardly out the open front. A spray tube is rotatably mounted on the bottom of each lateral side portion of each said dish rack and has a plurality of spray outlets spaced along the tube and directed generally tangentially in the same direction for causing rotation of the tube. A water supply manifold extends up the rear wall of the dishwasher. A releasable water connection device and conduits mounted on each dish rack connect the manifold to the spray tubes for supplying the water from a pump. Spray spinners are centrally mounted below each dish rack. The spray tubes provide a thorough spray at the lateral sides that the spinners may not reach in a very wide dishwasher. Other rotating spray tube arrangements are also disclosed.

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.
