Low Cost Pyrolytic Residential Gas Range Oven. Final Report, April 1983-April 1991

摘要

The Final Report covers the residential gas oven product development completed between April 1983 and April 1991. The program objective was to develop and commercialize an appliance that would reduce the cost differential between gas and electric-free, standing self clean (900 F pyrolytic) ranges, while maintaining or improving the performance of the gas oven. The focus of the report is the development of a single burner resembling a conventional waist-high broiler unit mounted at the top of the oven cavity that would provide bake, broil and self clean functions. A blower was used to change the character of the flame from a broil (when the blower is off) to a bake burner. The blower was also used to circulate air throughout the cavity during baking and self-cleaning operations to maintain uniform cavity, create uniform wall temperatures and produce a convection baking oven. During broiling, the fan was shut off and an appropriately designed flame spreader provided the radiant feature needed for broil. The oven system design results include bake, broil and self clean performance per ANSI Z21.1 standards and range manufacturer's test conditions. Oven prototype designs and photographs of the Hardwick/Magic Chef and Roper/GE prototype ovens are also presented.
