摘要： 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 (8) 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.

摘要： An induction heating apparatus is capable of stop heating without excessively boosting output voltages of a booster circuit and a power factor correction circuit. The induction heating apparatus includes a boosting function unit, an inverter circuit, and a booster circuit controller. The boosting function unit includes a power factor correction circuit and a booster circuit, and boosts an input direct-current power to a direct-current voltage having a peak value larger than the peak value of the input direct-current power by turning on/off a switching element. The inverter circuit includes a heating coil, and inputs the direct-current voltage output by the boosting function unit to generate a high frequency current in the heating coil by turning on or off a different switching element. The booster circuit controller stops a boosting operation of the boosting function unit without a prescribed delay from the stop of an operation of the inverter circuit.
