Abstract

Abstract A rice gruel cooker suited for heating in a microwave range includes a bowl, a perforated rice container placed in the bowl and having a space for accommodatng rice, and a lid held above the top end of the bowl. During heating, boiled water circulates actively through the space containing the rice and boils the rice uniformly without production of cores in rice particles despite quick heating in the microwave range. Specified lid position well prevents overflow and/or scattering of boiled water during cooking.
