DEVICE OF ENERGY INPUT FOR MICROWAVE OVEN Russian patent published in 2013 - IPC H05B6/64 

FIELD: electricity.

SUBSTANCE: device of energy input into a microwave oven is proposed, which comprises a wave guide, supplying microwave energy from a magnetron to a heating chamber, a radiator installed in the end of the wave guide and made in the form of a window in the wall of the working chamber, a radiolucent safety screen that closes the window of the radiator at the side of the working chamber, differing by the fact that the radiolucent safety screen is made in the form of M double-face wedges with parallel ribs and the angle at the top equal to; Δ=180-2×arctg√ε, where 6 - dielectric permeability of wall material, M=1,2…, installed tightly to each other, and relative to the radiator so that the electric vector of the radiator's field is perpendicular to ribs of the wedges.

EFFECT: increased efficiency factor and safety of a microwave oven by reduction of reflected electromagnetic energy from a safety screen.
