Abstract

A control apparatus for heating, defrosting and/or cooking foods to be heat-treated by exposure to microwave energy at a given location inside a closed cooking chamber includes a microwave generator beaming microwave energy into the cooking chamber, and a sensor detecting the state of the food and controlling the energy beamed into the cooking chamber. The sensor is disposed in the cooking chamber filled with microwave energy between the microwave generator and the given location for food exposed to microwave energy, for detecting a value for microwave energy potential and controlling the output of the microwave generator.
