Abstract
An induction heating device includes a case, a working coil, a cover plate, a luminous element, a light guide disposed around the working coil, an input interface that is flush with an upper surface of the cover plate, a first controller configured to control driving of the working coil and the luminous element and to detect a position of one or more objects disposed on the upper surface and an arrangement sequence of the one or more objects placed on the upper surface, and a second controller configured to receive, from the first controller, information on the position and the arrangement sequence of the one or more objects, and control the input interface to display an image corresponding to a heating zone for the one or more objects based on the information on the position and the arrangement sequence of the one or more objects.
