Disclosed is an electric rice cooker which includes a pot to hold rice and water, an inner case defining a heating space between the inner case and the outer peripheral and bottom surfaces of the pot, an outer case supporting the inner case, and at least one heater disposed in the heating space at a fixed distance from each of the pot and the inner case for heating air in the heating space to circulate the same by convection, thereby heating the pot and the rice and water in the pot from the upper portion.

An apparatus for cooking rice substantially under atmospheric pressure, comprising: a pot for holding cooking materials including water and an amount of rice to be cooked, said pot having a peripheral wall and a bottom having an outer edge connected to said peripheral wall, said pot being made of a material that conducts heat well; an inner case for containing and supporting said pot and defining a continuous, substantially sealed heating space between said inner case and said pot, said heating space defining an area where heated air is circulated by convection; an outer case supporting said inner case; and at least one electric heater for heating said heated air and having a diameter smaller than the outside diameter of said pot and located at an underside position of said pot, said position being defined between and separated from said pot and inner case in the vicinity of and following the circumference of said pot bottom outer edge so that said pot, and thus the cooking materials in said pot, are gradually heated substantially under atmospheric pressure, from the upper to the lower portion thereof to the optimum temperature for the whole of said amount of rice and each portion of the cooking materials remains at the optimum temperature for the substantially same length of time in order for said amount of rice to uniformly absorb said water.
