ABSTRACT:
A rice cooker includes an interlock that prevents the user from sliding the cooking pot out of the cooker without first disengaging internal assemblies that would otherwise be damaged. The rice cooker operates in any of three user selectable modes: a fully automatic mode in which the rice cooker measures out a user selected quantity of internally stored raw, unwashed rice, washes the rice, cooks the rice and then keeps the rice warm; a cook and keep-warm in which the cooking pot of the rice cooker is loaded with premeasured and washed rice from an external source and the rice cooker cooks the rice and keeps it rice warm; and a rice warming mode in which the cooking pot is loaded with already cooked rice and maintains it at a serving temperature. A startup routine checks that a pot is installed, that a lid is on the pot, that an upper pot cover assembly is at a required height, that a platform is in its latched position, and that a washer container is in its stowed position. If any check fails, an alarm sounds, and/or further operation is prevented.
