ELECTROMAGNETIC WAVE CUTOFF AND TRANSFORMER FOR MICROWAVE OVEN

摘要

PURPOSE: A microwave cutoff and a transformer for a microwave oven are provided to stabilize ground by a ground technique having a coiled transmission line or a single connection point, to maximize effect of microwave cutoff by simply changing a structure and to reduce microwave and a manufacturing cost. CONSTITUTION: A microwave cutoff for the microwave oven includes a magnetron(M) generating electric wave for heating foods, a transformer(T) receiving external AC voltage and outputting into DC high voltage for generating voltage required for generating electric wave of the magnetron, an external case wrapping the outside of each component, and a ground wire(L1) arranged near to the external case side and connected and grounded in a single connection point for stabilization of a power source and restriction of noise.
