ELECTRIC HEATING RANGE

PURPOSE:To provide an electric heating range having a high safe feature capable of producing a high temperature of about 1,200 deg.C-1,250 deg.C by a method wherein rods of silicon carbide are utilized as a heating source, an electric capacitance is made large, a heating part of the range is made deep and a ring heater is arranged at the opening. CONSTITUTION:An opening arranged at a proper position of a ceiling plate 2 of a base block 1 is made such that a ring heater 3 having an electric heating source buried therein is mounted in such a way as the top surface of the ring heater 3 and the surface of the ceiling plate 2 make a flush plane to each other, a heating part 4 having a diameter of inner circumferential surface larger than the inner diameter of the ring heater 3 is formed below the ceiling plate 2 down to a proper depth thereof, a proper number of rods of silicon carbide 5 are arranged side by side at the bottom part of the heating part 4, and electrically connected to these heating sources through thyristors 6, 7 and 8 for feeding and controlling an electric current in a non-stepwise manner.
