Electric tea pot, pan or plate warmer of low heat level - has bimetallic or corrugated thin, flexible metal plate to conform closely to bottom of pot placed on top

摘要

An electric heat radiator of resistance wire (6) with electrical connections (7) is installed in a cavity (9). Metal plates (2,5) at the top and sides present low wall strength so that an even temp. is quickly attained. Heat insulation (4), locked in by the outer skin (3), prevents loss of heat. The top plate (2) is of either bimetal or corrugated sheet metal sot that it adapts closely to the base of the pot, pan or plate placed on it. Mechanical supports (8) prevent the metal sheet from becoming permanently deformed through a heavy load or from cleaning. ADVANTAGE - Small energy consumption and low heat loss with rapid regulation of evenly distributed temp.
