An indicator for an induction heating device including a working coil, the indicator comprising:
- a magnetic flux sensing coil that is configured to (i) sense magnetic flux generated in a state in which the working coil is driven and (ii) convert the sensed magnetic flux into current;
- a rectifying portion that is configured to rectify current converted by the magnetic flux sensing coil;
- and
- a light emitting module that is configured to emit light based on current rectified by the rectifying portion.
An induction heating device comprising:
- a working coil portion that includes a first working coil and a second working coil;
- a magnetic flux sensing coil, wherein a first portion of the magnetic flux sensing coil is arranged on or over the first working coil and a second portion of the magnetic flux sensing coil is arranged on or over the second working coil, the magnetic flux sensing coil being configured to (i) sense magnetic flux generated by at least one of the first working coil or the second working coil and (ii) convert the sensed magnetic flux into current;
- a rectifying portion that is configured to rectify current converted by the magnetic flux sensing coil;
- and
- a light emitting module that is configured to emit light based on current rectified by the rectifying portion.
