Abstract
A steam cooking device which includes a pressure accumulating steam boiler and a steaming cabinet is disclosed. The pressure accumulating steam boiler heats liquid water and accumulates a steam having a pressure between 1.1 and 5.0 times atmospheric pressure. The steaming cabinet receives the steam from the pressure accumulating steam boiler to cook a foodstuff contained therein. To raise the temperature of a foodstuff accommodating chamber within the steaming cabinet from a room temperature to a cooking temperature, a WH1 amount of energy is consumed by an electricity-heat conversion unit in the pressure accumulating steam boiler. A foodstuff accommodating chamber within the steaming cabinet has a volume of V1. The steam cooking device satisfies V1/WH1>160. The cooking temperature is between 101° C. and 150° C. and is lower than or equal to the temperature of the steam when the steam is outputted from the pressure accumulating steam boiler.
