PROBLEM TO BE SOLVED: To prevent burning of coffee liquid remaining on the bottom of a heat-insulated container by stopping the heating if the empty heat-insulated container is heated. SOLUTION: Heating by a heating means 2 is stopped when the detected temperature rises while heating the empty heat-insulated container 1 by a heating control means 4 which heat-insulates the heating means 2 at prescribed controlled temperature based on the temperature detected by a temperature detecting means 3. Accordingly, the temperature rise of the heating means 2 is inhibited and the burning in the heat-insulated container 1 can be prevented. COPYRIGHT: (C)2006,JPO&NCIPI
