YTUPPVERMNINGSANORDNING INNEFATTANDE EN MASSIV, PLAN PLATTA

摘要

A low thermal mass, solid plate surface heating unit having a top utensil-supporting surface of composite metal of high thermal conductivity and corrosion and oxidation resisting materials. A metal sheathed electrical resistance heating element is pressed against the underside of the composite plate by an embossed back-up plate. This back-up plate is attached to the composite plate at a plurality of points that are spaced from the heating element so as to allow limited sliding movement between the heating element and the composite plate and thereby prevent warpage of the composite plate.
