INDUCTION HEATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/091269
Kind Code:
A1
Abstract:
An induction heating apparatus comprises: a coil; an inverter configured to provide a driving current to the coil; a current sensor for measuring the driving current of the coil; and a control unit for controlling the inverter so that the driving current follows a target current based on a user input. The control unit can maintain a switching operation of the inverter on the basis of the detection time of the driving current smaller than a reference current being less than the reference time, and can stop the operation of the inverter on the basis of the detection time of the driving current smaller than the reference current being equal to or greater than the reference time.
