Induction heating device having improved indicator structure

An induction heating device comprising:

• a case;
• a cover plate coupled to the case and configured to seat an object on an upper surface of the cover plate;
• a working coil located inside of the case and configured to provide heat to the object located on the cover plate;
• a base plate located vertically below the working coil;
• a light guide located on the base plate around the working coil, the light guide comprising a light-emitting surface configured to indicate at least one of an output intensity of the working coil or an operation state of the working coil;
• and
• a light-emitting element located vertically below the light guide and configured to emit light toward the light guide based on operation of the working coil,
• wherein the light guide further comprises:
• a light-guiding portion that has a lower surface having a parabolic shape, and an upper surface including the light-emitting surface, the upper surface extending in a first direction by a first length and the lower surface extending in the first direction by a second length less than the first length, and
• a light-guiding support that is configured to couple to the base plate and that surrounds at least a portion of the light-guiding portion, the light-guiding support being configured to reflect, toward the light-guiding portion, at least one of light that has been emitted from the light-emitting element or light that has been guided through the light-guiding portion.
