Abstract:
1. A state detection device for detecting an operating state of a high-frequency heating apparatus including a magnetron for generating microwave; comprising: a motion position determination portion which determines a motion position of a radio wave stirring member that operates periodically in order to relatively stir the microwave generated by the magnetron with respect to a heated subject; an anode current input portion which inputs a detected anode current of the magnetron; and a determination portion which determines one period of a periodical motion of the radio wave stirring member from information of the motion position determined by the motion position determination portion, then reads a corresponding value corresponding to the anode current inputted from the anode current input portion for a plurality of times during the one period and determines the operating state of the high-frequency heating apparatus based on a plurality of the corresponding values during the one period.
