ABSTRACT:
An induction heating cooking apparatus contains a cooker main unit (1), comprising a connector (17) attached to an operation part (7) of the cooker main unit (1) in a freely attachable/detachable manner. A probe (13) containing a thermistor therein is coupled to the connector (17). The probe (13) is inserted into the foodstuff to be cooked in a cooking pan (5), and the thermistor detects the temperature thereof. A light emitting device (23) installed in the connector (17) outputs a light signal in response to the output from the thermistor. This light signal is introduced into the cooker main unit (1) through a light transmitting part (25) formed at a bottom part (19) of the connector (17) and another light transmitting part (27) formed in the operation part (7), being received by a light receiving device (29). In response to the output from the light receiving device (29), a driving circuit drives an inverter. When no light signal is received, the inverter oscillates, and when the light signal is received, the inverter stops oscillating operation.
