Abstract: Disclosed herein are a refrigerator includes a housing, a door rotatably installed at the housing using a hinge, and a door driving system to open or close the housing using the door. The door driving system includes a motor to output power to open or close the door, a sun gear linked with the motor, a planetary gear linked with the sun gear, and provided to be rotated about an axis thereof and to revolve, an internal gear linked with the planetary gear and configured to transfer power generated by the motor to the hinge, and a carrier configured to be rotated linked with the planetary gear and selectively support the planetary gear to be rotated about the axis thereof. When the planetary gear is rotated about the axis thereof, the power of the motor is transferred to the internal gear and thus the door is automatically opened or closed.

Abstract: Provided herein is a door opening and closing apparatus capable of reducing torque of a motor required for removing an adhesive force between a door and a housing. The door opening and closing apparatus includes a motor configured to output power for opening and closing a door, a power transmission apparatus configured to transmit the power of the motor to a hinge by rotation of a plurality of driving gears, and an auxiliary apparatus configured to generate an auxiliary force for moving the door at a closing position toward an opening position, where the auxiliary force is generated at the auxiliary apparatus by the power of the motor before the power of the motor is transmitted to the hinge through the power transmission apparatus.
