Cooking device

A cooking device comprising:

• a main body configured to accommodate an inner pot;
• a top plate provided in a lid cover coupled to the main body;
• a rotation cover rotatably coupled to the top plate to be rotatable along an edge of the top plate;
• a first pressure control device comprising:
• a first lower cylinder which comprises a first lower flow path communicating with an accommodation space in the inner pot,
• a first upper cylinder which is disposed on the first lower cylinder and comprises a first upper flow path,
• a first weight which is disposed on the first upper cylinder and configured to open/close the first upper flow path depending on a steam pressure of the accommodation space in the inner pot, and
• a shutter structure which is configured to switch between an opening position for opening an outlet of the first lower flow path such that the first lower flow path and the first upper flow path communicate with each other and a closing position for closing the outlet of the first lower flow path such that the first lower flow path and the first upper flow path do not communicate with each other;
• and
• a second pressure control device comprising:
• a second cylinder which comprises a second flow path communicating with the accommodation space in the inner pot, and
• a second weight which is disposed on the second cylinder and configured to open/close the second flow path depending on the steam pressure of the accommodation space in the inner pot,
• wherein the first pressure control device is configured to maintain the steam pressure of the accommodation space in the inner pot at a first pressure when the shutter structure is in the opening position and the steam pressure of the accommodation space in the inner pot is capable of being increased to a pressure higher than the first pressure when the shutter structure is in the closing position.
