PURPOSE: A dry washing machine is provided to prevent spark generation by disabling a magnetron according to a result of sensing the indication of the spark generation before the spark generation. CONSTITUTION: A dry washing machine comprises a spark predicting sensing part which senses generation indication such as radio frequency wave signal, which appears before spark generation, at drying the laundry by a microwave. An amplifier amplifies a signal sensed by the spark predicting sensing part. A controller receives the amplified signal to judge whether the received signal means the generation indication appearing before the spark generation, and controls driving of a magnetron so as not to generate the spark. |
