MICROWAVE OVEN WITH "SMOOTH" HEATING Russian patent published in 2006 - IPC H05B6/64 

FIELD: microwave engineering.

SUBSTANCE: microwave oven has strip antenna for circle-polarized field, mounted inside the heating chamber, and microwave generator, positioned in body of electronic block having common wall with heating chamber, and also coaxial rotary section and electric drive connected to its external conductor. Coaxial input of strip antenna of circle-polarized field is mounted with possible axial turn in aperture, made in wall of heating chamber common with body. External conductor of coaxial rotary section is connected to external conductor of coaxial output of microwave generator by means of flanged connection with possible axial rotation and is rigidly connected to external conductor of input of circle-polarized field strip antenna. Central conductor of coaxial rotary section is rigidly connected to central conductor of coaxial input of strip antenna of circle-polarized field and central conductor of coaxial output of microwave generator and has average flexible portion, made with possible twisting, which is connected to rigid end portions, each one of which is rigidly held in aperture of dielectric washer.

EFFECT: improved efficiency of microwave oven operation due to increased evenness of heating by energy of microwave field of processed product, utilization of "smooth" thermal processing mode and its stability, increased overall efficiency, decreased consumption of power from power grid.
