摘要： 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 (M) configured to output power for opening and closing a door (D), a power transmission apparatus (40) configured to transmit the power of the motor to a hinge (Z) by rotation of a plurality of driving gears, and an auxiliary apparatus (30) 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.

摘要： PROBLEM TO BE SOLVED: To provide a door opening/closing mechanism capable of reducing torque of a motor necessary for cancelling magnetization between a door and a housing.SOLUTION: A door opening/closing mechanism for a refrigerator includes: a motor M configured to output power for opening/closing the door; a power transmission mechanism 40 configured to transmit power of the motor M to a hinge by rotation of a plurality of drive gears 45; and an auxiliary mechanism 30 configured to generate auxiliary force for moving the door at a closed position toward an open direction. The door opening/closing mechanism is configured to generate the auxiliary force of the auxiliary mechanism 30 by power of the motor M, before transmitting the power of the motor M to the hinge Z through the power transmission mechanism 40.SELECTED DRAWING: Figure 34
