Cooking device

A cooking device comprising:

• a top plate configured to cover an inner pot;
• a steam discharge structure comprising:
• a post comprising a steam discharge passage connected to interior of the inner pot;
• a moving member disposed on the post to surround at least a portion of a side surface of the post, and configured to move, based on a rotation of the moving member, in a first direction which is perpendicular to a direction in which a top surface of the top plate extends by a user's manipulation;
• a steam blocking member passing through a portion of the moving member, and configured to open/close the steam discharge passage based on a movement of the steam blocking member in the first direction;
• and
• an elastic member configured to provide an elastic force to the steam blocking member;
• a rotating cover coupled onto the top plate to be rotatable along an edge of the top plate, and comprising a first guide hole spaced apart from a rotation center of the rotating cover by a first distance, and a second guide hole spaced apart from the rotation center by a second distance greater than the first distance;
• and
• a locking structure comprising a locking protrusion disposed inside the first guide hole and the second guide hole in the rotating cover, and configured to move in a second direction parallel to the direction in which the top surface of the top plate extends to be coupled to or separated from the inner pot based on a rotation of the rotating cover,
• wherein the steam blocking member comprises:
• a piston passing through the moving member to be disposed in the steam discharge passage, and including a moving protrusion disposed at an upper portion protruding from the moving member;
• and
• a blocking cap coupled to a lower portion of the piston, and configured to block the steam discharge passage,
• wherein the moving member is configured to move between a first level, a second level higher than the first level, a third level higher than the second level, and a fourth level higher than the third level,
• wherein the blocking cap is configured to block the steam discharge passage with a first elastic force provided by the elastic member when the moving member is in the first level,
• wherein the blocking cap is configured to block the steam discharge passage with a second elastic force smaller than the first elastic force, provided by the elastic member when the moving member is in the second level,
• wherein the blocking cap is configured to block the steam discharge passage with a third elastic force smaller than the second elastic force, provided by the elastic member when the moving member is in the third level, and
• wherein, while the moving member moves from the third level to the fourth level by the user's manipulation, the moving member moves the moving protrusion of the piston such that the blocking cap opens the steam discharge passage,
• wherein a degree of compression of the elastic member is controlled by a movement of the moving member in the first direction with respect to the post, thereby controlling a magnitude of the elastic force provided to the steam blocking member, and
• wherein the post includes a body and a rotating protrusion protruding from the side surface of the body and extending in an oblique direction, and the moving member includes a receiving groove configured to receive the rotating protrusion.
