    摘要： The present disclosure relates to an enamel composition, a method for preparation thereof, and a cooking appliance using the same, which provide excellent cleaning performance, reduce a defect caused by carbon gases when an enamel coating is implemented on a base material made of cast iron, and provides excellent thermal shock resistance and durability. In the enamel composition according to the disclosure, components implementing glass and components having catalytic performance have an optimal component system, thereby ensuring excellent thermal shock resistance and durability. The enamel composition of the present disclosure has a component system that helps enamel cast iron as well as low carbon steel, thereby ensuring excellent cleaning performance, thermal shock resistance and durability. The enamel composition of the present disclosure is appropriate for a cooktop grate, a hob burner, and the like which directly contact a fire and are exposed to repetitive thermal shock.

    摘要： The present invention relates to a composite cooker having a plurality of heat sources. The cooker, according to one embodiment of the present disclosure, may comprise: a housing having a cavity formed therein; a door connected to the housing so as to open/close the cavity; a MW heating module for radiating microwaves to the cavity; an IH heating module for radiating a magnetic field toward the cavity; and a shielding member for enabling the magnetic field generated by the IH heating module to pass through, while blocking the microwaves radiated from the MW heating module. The shielding member may comprise carbon fiber.
