Abstract: A cooker includes: a heating chamber on which a first object to be heated is placed; a heating plate on which a second object to be heated is placed; an upper heat source provided on an upper side of the heating chamber, and a lower heat source provided on a lower side of the heating chamber and including at least a high-frequency heat source; an operation unit configured to receive an input of information on a heating treatment; and a control unit configured to individually control the upper heat source and the lower heat source, based on the information on the heating treatment. The cooker further includes a reflecting portion provided below the heating plate and configured to reflect leftwards and rightwards high-frequency waves supplied from the high-frequency heat source.

Abstract: It is an object of the invention to provide a cooking apparatus which can keep a food warm at a proper temperature without damaging the food. The interior of a heating chamber 12 is heated by heating chamber interior heating means 13 and steam is supplied into the heating chamber 12 by steam supply means 18. At the then time, since a control part 19, based on the temperature of the interior of the heating chamber detected by heating chamber temperature detect means 20, controls the heating chamber interior heating means 13 and steam supply means 18 in such a manner that the interior of the heating chamber 12 provides a given temperature, a food 11 can be maintained at a heat retention temperature suitable for keeping the food warm. This can solve the problem found in the conventional cooking apparatus that the surface of the food dries and burns.
