ABSTRACT:
An inverter cooker with a high voltage/low voltage separating device, which can protect the user from accident and prevents the inverter cooker from malfunctioning by separating a low voltage circuit portion from high voltage circuit portion regardless of the performance of signal transmission. According to the inverter cooker, the signal intercommunicating between the high voltage circuit portion such as an inverter controller or a current detector and the low voltage circuit portion such as a function key input device or a system controller is performed through the high voltage/low voltage separating device which has a plurality of photo-couplers.
