Rotary compressor and home appliance including same

A home appliance comprising:

• a rotary compressor including:
• a case;
• a cylinder inside the case, the cylinder including
• an internal space,
• a rolling piston configured to eccentrically rotate in the internal space,
• a vane configured to reciprocate in contact with the rolling piston such that the vane and rolling piston together are configured to divide the internal space of the cylinder into a suction chamber and a compression chamber,
• a suction port to allow low pressure refrigerant to flow to the suction chamber, and
• a discharge port to allow high pressure refrigerant to be discharged the compression chamber;
• a drive device including a rotation shaft connected to the rolling piston and a motor configured to rotate the rotation shaft to eccentrically rotate the rolling piston;
• and
• a valve member, fixed to a side surface of the vane, and configured to close the discharge port while the low pressure refrigerant is being compressed in the compression chamber and open the discharge port to discharge the high pressure refrigerant from the compression chamber as the vane reciprocates back and forth, wherein
• the home appliance is configured to control temperature through heat exchange using refrigerant.
