Abstract

Industrial microwave oven for the thermal treatment of products, which microwave oven (1) mainly consists of an oven space (32) which is limited by a metal case (9); one or several magnetrons (25) onto which are connected one or several wave guides (14-15) which open into the oven space (32) with one outlet (29) via openings in the upper wall (20) of the above-mentioned case (9); one or several antenna radiators (30) provided in the above-mentioned outlets (29), means for cooling the magnetrons (25) by means of gas flows, characterised in that at least a part of the above-mentioned gas flows are blown into the oven space (32) via the aforesaid wave guides (14-15).
