Abstract

PURPOSE: To provide a safety means being able to stop the high-frequency oscillation by melting a fuse even upon door opening in the case of the safety switch trouble.
CONSTITUTION: When the contact of a safety switch 2 is in the trouble condition, i.e. closed state, if the door is opened during cooking in the closed condition of a timer contact 8, safety switches 13, 14 are changed over the closing of contacts C- NC, thereby the source voltage applied to a high voltage transformer 9 is supplied through fuses 10, 10' as indicated by an arrow S. The current fuses 10, 10' is therefore, melted immediately to break the application of the source voltage to the high voltage transformer.
