• a lid coupled to an upper portion of the main body so as to be opened/closed;
• a pressure switching selection unit arranged to pass through the lid, in which a pressure discharge passage, which is selectively opened or closed to discharge an internal steam of the inner pot, and a pressure control passage, which is selectively opened or closed according to a level of pressure inside the inner pot when the pressure discharge passage is closed, are disposed in the pressure switching selection unit in series in a multi-stage arrangement;
• and
• a handle portion provided on an upper surface of the lid,
• wherein the handle portion interworks with an inner pot locking unit to lock the inner pot, and
• the pressure discharge passage is opened or closed by a link unit interworkinq with the handle portion,
• wherein the pressure switching selection unit comprises:
• a base cylinder formed therein with the pressure discharge passage and disposed to pass through a lower surface of the lid such that a lower end of the base cylinder communicates with the inner pot;
• a control body portion formed therein with the pressure control passage and disposed on an upper portion of the base cylinder;
• a lifting cylinder configured to surround an outer periphery of the base cylinder, coupled to a lower end of the control body portion and moved up and down by the link unit to switch the opened/closed states of the pressure discharge passage;
• a pressing unit configured to press the lifting cylinder to maintain the opened/closed states of the pressure discharge passage;
• and
• a pressure weight provided at an end of the pressure control passage to open or close the pressure control passage according to a level of pressure inside the inner pot.
