MICROWAVE HEATING DEVICE Russian patent published in 1996 - IPC

FIELD: microwave engineering. SUBSTANCE: device has microwave oscillator, heating chamber, and coaxial feeder section one of whose ends is sorted out and other held open; coaxial feeder section is connected through exciting element to microwave oscillator and its open end is connected to heating chamber; maximum internal size of heating chamber equals that of external conductor of coaxial feeder section or is greater than that by maximum 0,2λ,; inner size of external conductor of coaxial feeder section is (0,23...,48)λ.. Coaxial feeder section may be round or elliptical in cross-sectional area, or it may be rectangular. Heating chamber is round-, elliptical-, or rectangular-section structure accommodating insulating plate, (0,005...0,55)λ, thick, mounted directly on open end of coaxial feeder section, or spaced maximum 0,2λ from it. EFFECT: improved design. 1 dwg
