Abstract

Method of controlling a microwave oven having a microwave-producing tube such as a magnetron, characterised in that it consists: - at the start of a cycle of processing a foodstuff or a drink, in operating the microwave-producing tube at its maximum power Pn for a time at most equal to a time for reheating this microwave-producing tube or one or more accessories for powering and cooling this tube, and taken as a reference, such as a transformer, that is to say the temperature rise time, from its or their rest temperature, to its or their predetermined operating temperature limit and - in the remainder of this processing cycle, in operating the microwave-producing tube at a preset power for normal working, less than its maximum power Pn. Microwave oven implementing this method. <IMAGE>
