Refrigerator

A refrigerator comprising:

• a main body;
• a storage room in the main body;
• a door couplable to the main body so that, while the door is coupled to the main body, the door is rotatable to open and close the storage room;
• a lever device mountable on the door and including:
• a case,
• a lever including:
• a first end, and
• a second end couplable to the case so that, while the second end is coupled to the case, the lever is rotatable about the second end, and
• a spring arrangeable inside the case and couplable to the lever so that, while the spring is coupled to the lever, the spring is compressed and expanded along a direction of a longitudinal length of the spring according to a rotation of the lever;
• a cam mountable on the main body and including a cam face, and the cam face including:
• a first contact surface,
• a second contact surface, and
• an inflection point between the first contact surface and the second contact surface;
• wherein, while the lever device is mounted on the door and the cam is mounted on the main body, the lever device and the cam are configured so that:
• while the door is being rotated to close the storage room, the first end of the lever contacts the cam and is moved along the cam face such that:
• the first end of the lever is moved along the first contact surface and the lever is rotated in a first direction so as to compress the spring and accumulate an elastic force in the lever device,
• after the first end of the lever is moved along a length of the first contact surface, the first end of the lever contacts the inflection point, and
• after the first end of the lever contacts the inflection point, the first end of the lever is moved along the second contact surface and the lever is rotated in a second direction, opposite to the first direction, so that the spring decompresses and the accumulated elastic force is transmitted to the door in a direction of rotating the door to close the storage room.
