Abstract

A high-frequency furnace for high-frequency heating using ultra-high frequencies in which the ultra-high frequency oscillations provided by an ultra-high frequency generator are supplied to a folded waveguide system in the form of a plurality of interconnected waveguide parts., each two pieces of adjacent waveguides being separated from each other by a common boundary wall, and in which the waveguide system is provided with a channel to drive through it the object to be heated transversely to the boundary walls common of juxtaposed waveguide parts, each wall having for this purpose a through opening, characterized in that the folded waveguide system of the high-frequency furnace is provided with a separation wall that divides the waveguide system for oscillations of UHF in two separate portions, the frequency generator being connected ultra-high frequency to the coupling openings, located one on each side of the separation wall, through a power coupling device that couples the ultra-high frequency oscillations from the ultra-high frequency generator, without variation in the type of wave, through the two coupling openings on each side of the partition wall.
