PROBLEM TO BE SOLVED: To eliminate the possibility of fungus contamination, prevent the rice from being swollen by the difference in the temperature distribution and suppress the deterioration of rice due to heat preservation. SOLUTION: In a sucking process, an opening/closing valve A31 is closed, an opening/closing valve B32 is opened, an opening/closing valve C37 is opened, an opening/closing valve D38 is closed, a suction device 34 is actuated to suck the air in a space surrounded with an inner pot 23 and an inner lid 28 and make the pressure inside the rice cooker smaller than the atmospheric pressure. Therefore, an excessive moisture which is not absorbed in the rice in the rice cooker is evaporated to lower the temperature to that equivalent to the vaporization latent heat of water, and the output of a pressure sensor 40 is set to a steam pressure of 31 kPa (234 mmHg) which is equivalent to 70°C suitable for the heat preservation temperature of the rice.
