Abstract (en)
[origin: EP0163106A1] 1. Electric hotplate with a hotplate body (12), on whose underside heating resistors (23, 24, 25) are embedded in grooves (20, 21, 22), which are arranged in spiral turns and whereof one is a main heating resistor (24, 25), which is controllable by a timing energy control device (40) and with an additional heating resistor (23), which can he switched in during an initial cooking phase and can he subsequently switched off by a thermal or time switch (34), characterised in that each spiral turn (36) contains three substantially parallel grooves (20, 21, 22), whereof the outer one contains the additional heating resistor (23) and the two others in each case one main heating resistor part (24, 25), which are connected in series for forming the main heating resistor.
