Abstract

For an electric range featuring combined heating by microwave energy, and/or thermal energy a compact and space-saving construction impervious to microwave energy is provided by the thermal-energy source being arranged in a hood which is impervious to microwaves and which is formed at the top of the cooking space. A reflector associated with the thermal-energy source and situated in the transition area between the heating space and the cooking space is connected to a metal grid in an electrically conductive manner and is connected to but insulated from the housing.
