Abstract
An induction heat cooking device is provided that finishes preheating in a short time and maintains the temperature obtained at the finish of the preheating. The induction heat cooking device includes a heating coil for heating a cooking container by induction, an inverter circuit for providing a high frequency current to the heating coil, an operation unit including an operation mode setting unit for setting an operation mode of the inverter circuit, an infrared sensor for detecting an infrared light that is emitted from a bottom surface of the cooking container, a control unit for controlling an output of the inverter circuit based on an output of the infrared sensor and a setting inputted to the operation unit, and a notification unit.
