Abstract

An electric hotplate, having an insulator bearing at least one electrical heating resistor, comprising: a metal plate heatable by the at least one electrical heating resistor, having substantially flat upper and lower surfaces and a downwardly directed rim near its outer circumference, the rim and lower surface defining a space therebetween, and the upper surface forming a cooking surface for receiving cooking vessels placed thereon; the insulator having a plurality of insulating layers, the at least one heating resistor being disposed on the upper surface of the uppermost layer; a basket-shaped metal lattice surrounding the insulator about its outer surface and holding the plurality of insulating layers together, the insulator and metal lattice forming an independently positionable heater/insulator assembly; and, fasteners at the rim for engaging the metal lattice and holding the heater/insulator assembly in position at least partly in the space.
