Title:
INDUCTION HEATER COOKER
Document Type and Number:
Japanese Patent JPH11329696
Kind Code:
A
Abstract:
To effectively adjust the temperature at a plurality of levels, in temperature adjusting of a pot on an induction heating cooker.
As the temperature of a pot 9 rises, the magnetism of the pot changes and a current value of a flywheel diode in a switching element 3 rises, and when on-off operation of the switching element 3 is controlled by a control circuit 8 so that the current value of the diode is stabilized at a set value, stable temperature control utilizing the change of the magnetism of the pot is made possible at a plurality of temperature levels, by providing a plurality of set values of current of the diode.
