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. When a preheating heating mode is selected as an operation mode, a control unit () arranged in the induction heat cooking device starts operation in a preheating mode in which a cooking container is heated with a first heating output. When an increment of an output value of an infrared sensor exceeds a first predetermined increment since the heating starts with the first heating output, the control unit causes a notification unit to notify a user that the preheating is finished, and the operation mode is changed to a waiting mode for performing heating with a second heating output that is lower than the first heating output. Further, when the user sets a heating power by means of a heating power setting unit in the preheating mode, the control unit prohibits changing to the heating power set by the user. When the user sets a heating power by means of a heating power setting unit in the waiting mode, the control unit permits changing to the heating power set by the user, and the operation mode is changed to a heating mode for performing heating with a third heating output corresponding to the heating power set by the user.
