FIELD: domestic appliances. SUBSTANCE: microwave oven has heating chamber, electronic module with radiating system incorporating microwave oscillator, disk radiator, base and ring, and waveguide channel (coaxial line section). Oven is of modular design; electronic module is packaged separately from heating chamber. There is no metal case (screen) common for electronic unit and heating chamber. To prevent leakage of microwave energy from heating chamber over perimeter of coupling hole for input of microwave energy, depression is made in heating chamber wall to receive electromagnetic packing; throttling groove is provided over perimeter of metal bezel on open end of electronic unit facing heating chamber; slot is made for electromagnetic packing over perimeter of ring placed on perimeter of coupling hole for microwave energy input. EFFECT: reduced metal input and mass of oven, reduced cost, facilitated manufacture. 3 cl, 1 dwgc
