Claims20
A cooking appliance comprising:
- a housing that defines a cavity configured to receive an object to be heated;
- a door connected to the housing and configured to open and close the cavity;
- a working coil that is configured to generate a magnetic field through a first surface of the cavity;
- a thin film that is disposed between the cavity and the working coil;
- and
- a plate that defines the first surface of the cavity and is in contact with the thin film, the plate being disposed between the cavity and the working coil,
- wherein the working coil is configured to, by the magnetic field, induce an eddy current to selectively one of the thin film or the object in the cavity to thereby heat the object.
