ABSTRACT:
Cleaning according to an evaporating dish cleaning mode or heating chamber cleaning mode is implemented based on a signal inputted by the control part. In the heating chamber cleaning mode, condensation is generated on the inner surface of the heating chamber11by steam, and the soil adhered to the inner surface of the heating chamber11is allowed to float to be in a state of removing it easily. In the evaporating dish cleaning mode, a cleaning liquid made of citric acid solution is pumped into an evaporating dish35, it is heated to a predetermined temperature, and it is left therein. Therefore, calcium and magnesium deposited on the evaporating dish35are allowed in a state of removing them easily.
