Abstract

High-frequency furnace for heating by high frequency with the help of ultra-high frequency oscillations, comprising an ultra-high frequency generator whose output circuit is coupled to a heating chamber that is enclosed by metal walls and is provided of a feeding opening for the introduction of the articles to be heated in the heating chamber and with a door which, when closed, closes the heating chamber by means of a metal wall and on the outside of the feeding opening together with a closing wall provided on the heating chamber forms a seal for the emitted scattered radiation, characterized in that at least one of the sealing walls located on the outside of the feeding opening in a direction away from said feed opening comprises two successive sealing frames surrounding the feed opening and in the closed position of the door is linked to the opposite wall so as to be substantially flush with it, the sealing frame being adjacent to the metal feed opening and the following sealing frame consisting of a dielectric material in which it is distributed a powdery substance that absorbs ultra-high frequency oscillations.
