<p>A control unit for controlling a water feed unit, a heating unit, and a washing unit based on a detected temperature of a temperature detecting unit to execute at least a thermal capability estimating step, washing step, heating/rinsing step, and drying step compares a temperature rising-up ratio of the washing water in the thermal capability estimating step and a temperature rising-up ratio of the washing water in the washing step to detect a volume of an item to be washed and perform control. In this manner, it is possible to determine the volume of the dishes while suppressing variations of the wattage of the heater or an influence by power source voltage fluctuations in installation environment, so as to determine the volume of the dishes.</p> |
