Abstract
A food preparation oven includes a cooking chamber (1) in which a device (12) is provided for generating heat waves and for directing them in a suitably concentrated manner onto the surfaces (6, 7, 8, 9, 10,11) of the walls of the chamber (1); the device (12) is removably arranged in the cooking chamber (1) and is mobile therein so as to direct the heat waves onto the entire surface of the walls, the concentrated waves scanning the surfaces (6, 7, 8, 9, 10, 11) but covering only portions of them at any given time, creating only in and around these portions a high temperature which results in the pyrolysis of the impurities which have been deposited on the surfaces (6, 7, 8, 9, 10, 11) during the use of the oven. The heat waves can also be used for food preparation.
