摘要:
An induction heating cooker capable of accurately discriminating whether the material of a cooking container placed in the induction heating cooker is magnetic or non-magnetic, using a phase change in a resonant capacitor voltage of an inverter circuit and a switching pulse signal of the inverter circuit, irrespective of the load of the cooking container, and a method for operating the induction heating cooker. The induction heating cooker includes a power supply for rectifying an AC voltage, filtering the rectified voltage, and supplying the filtered voltage as an input voltage of the induction heating cooker, an inverter circuit for heating a cooking container placed in the induction heating cooker, using the voltage supplied from the power supply, and a container material discriminating unit for discriminating whether a material of the cooking container is magnetic or non-magnetic, based on a resonant capacitor voltage of the inverter circuit and a switching pulse signal of the inverter circuit, upon an initial operation of the induction heating cooker, whereby the cooking container is selectively heated in accordance with the result of the discrimination.

An induction-heating cooking apparatus, operation of which is interrupted by container eccentricity is disclosed. Upon receiving an input signal varying with the degree of eccentricity of a container, the apparatus changes a reference signal for determining the presence or absence of a small load in proportion to a pulse-width control signal controlling the width of an inverter driving pulse. Although the eccentricity of the container occurs in a normal heating operation and completely escapes from a cook zone, the apparatus determines the occurrence of a no-load state, and interrupts an operation of an inverter circuit, resulting in increased stability of a circuit and a product.
