Electric Cooker

An electric cooker is configured to cook in a pressure state and a non-pressure state of an inner pot, thereby improving the cooking quality and convenience of use. The electric cooker includes a main body provided, at an upper end thereof, with a flange portion and configured to accommodate an inner pot therein; a lid coupled to an upper portion of the main body and opened/closed by an opening/closing unit; a locking ring rotated by interworking with the opening/closing unit, selectively engaged with the flange portion, and provided, at an upper surface thereof, with a marker configured to indicate a rotational direction; a pressure switching unit arranged to pass through the lid and opened or closed by interworking with the opening/closing unit to discharge internal steam from the inner pot; a sensor unit configured to sense the marker when the locking ring is rotated to be locked or unlocked; and a control unit that activates power supply to the main body when a sensing signal is received from the sensor unit.
