Claim 8:
9. A half-flex type induction heating device, comprising:
a plurality of working coils installed in a case and disposed respectively in a plurality of zones spaced apart from each other;
a cover plate coupled to an upper end of the case and at which an object to be heated by at least one of the plurality of working coils is placed at an upper surface;
an input interface configured to receive a touch input from a user and to display a specific image, and embedded in the upper surface of the cover plate;
a first controller configured to control the specific image displayed on the input interface based on the touch input received from the input interface; and
a second controller configured to control driving of the plurality of working coils based on the touch input received from the input interface,
wherein, based on a touch input of a temporarily lowering icon displayed at a lower end of the input interface being provided from the user to the input interface, the second controller changes heating intensities of the plurality of working coils being driven among the plurality of working coils into a predetermined heating intensity,
wherein, based on a touch input of the temporarily lowering icon being received at the input interface:
the input interface provides the touch input of the temporarily lowering icon to the first controller, and
the first controller allows the temporarily lowering icon, displayed on the input interface, to blink based on the touch input of the temporarily lowering icon, and controls the input interface to display a heating intensity image, which indicates the predetermined heating intensity, in a state of being inactivated.
