Abstract
A microwave oven comprises a microwave radiation source, a microwave-activable bottom heater (4) on which the food is placed, and optionally an IR-radiating top heater, which all can be controlled via the control unit of the oven. Further, the oven comprises one or more sensors for sensing the temperature of the bottom heater (4) and feeding this information back to the control unit. The feedback temperature information makes it possible to impart the desired temperature to the bottom heater (4) by controlling the microwave radiation source and/or the top heater.
