• a seating unit extending upward from an end of the heating unit, and having at least one air outlet hole, with a lid seated on the seating unit;
• and
• a guide unit protruding from an outer surface of the container to guide heated air to the air inlet hole, said guide unit comprising:
• a plurality of circular protrusions concentrically arranged on a bottom of the container and having different diameters;
• a plurality of guide protrusions crossing the circular protrusions to guide heated air;
• at least one guide duct provided on a sidewall of the container to communicate with a space defined between at least two guide protrusions, thus guiding heated air to the air inlet hole;
• and
• air guide gaps provided at predetermined positions on the guide protrusions located between neighboring circular protrusions, and at predetermined positions on the circular protrusions located between guide protrusions, thus guiding the heated air.
