Abstract
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 configured to accommodate an inner pot; a lid coupled to an upper portion of the main body and having a handle portion provided at one side of an upper portion of the lid to interwork with an inner pot locking unit configured to lock the inner pot; a pressure switching unit arranged to pass through the lid and configured to switch or maintain an opened or closed state to discharge internal steam from the inner pot according to a rotation of the handle portion; and a pressure-responsive operating unit which is selectively opened or closed according to a pressure inside the inner pot in a pressure cooking mode in which the pressure switching unit is closed.
