1. A rice cooker comprising:
- a rice cooker main body;
a lid covering the rice cooker main body;
a lid detector to detect an open and close state of the lid;
an inner pan detachably accommodated in the rice cooker main body;
heating means for heating the inner pan;
control means for supplying and controlling electric power to the heating means, and for receiving a signal from the lid detector indicating an open or close state of the lid; and
an operation unit for instructing a start of rice cooking and for instructing a selection of a rice cooking function,wherein the control means is adapted to inhibit at least one instruction input of the operation unit if an open state of the lid is detected by the lid detector.

Abstract
A rice cooker does not cause malfunction if the operation unit is touched by mistake when closing the lid, and is capable of preventing boil-over without lowering the rice cooking performance. The rice cooker includes a main body, a lid for covering the top of the main body, an inner pan detachably accommodated in the main body, a heater for induction heating of the inner pan, a controller for controlling the supply of high frequency power to the heater, an operating unit, and a lid opening and closing detector or a rice gruel detector disposed in a steam tube of the lid. The controller inhibits operation signal input of the operating unit when detecting an open state of the lid, and controls the power supply to the heater when detecting a rise in the rice gruel. Therefore, the rice cooker prevents a wrong input in rice cooking when opening or closing the lid, and prevents boil-over of the rice gruel.
