Abstract
A microwave oven has electrical resistance heating elements (38a, 38b), a fan (36) for passing air over the heating elements and through the oven cavity (10) and a magnetron for delivering microwave power to the oven cavity. The oven is intended for use in commercial establishments such as cafes, petrol filling stations or railway stations and is capable of occupying a stand-by mode pending insertion of a foot item into the oven cavity (10). During the stand-by mode the electrical resistance heating elements are energized at a lower power level (continuously or in pulses) in order to provide a reservoir of heat which speeds the cooking process. The oven is capable of occupying the stand-by mode continuously.
