SUPERHIGH-FREQUENCY OVEN Russian patent published in 1997 - IPC

FIELD: microwave engineering. SUBSTANCE: oven has heating chamber, microwave oscillator whose output is connected through coaxial line section to radiating system incorporating disk-shaped radiator, base, and ring. Radiating system is separate module installed beyond heating chamber as follows. Made in one of heating chamber walls is communication port for microwave energy inlet filled with radio-transparent material. Ring is mounted otter perimeter of this port on external surface of mentioned wall of heating chamber for providing electric contact. Base plugged in it for providing electric contact has over its perimeter electromagnetic seal slot. Base has depression receiving radiator. Ring, base, and radiator are made of electromagnetic wave transmitting material. In addition, inner surfaces of two walls, of which one abuts against chamber wall facing communication port and other wall is placed against communication port, are ribbed. EFFECT: provision for uniform heating of products, including those of different mass and arrangement inside chamber due to uniform distribution of electromagnetic field. 4 cl, 1 dwg
