Abstract
The embodiment relates to a refrigerator. The refrigerator according to the exemplary embodiment includes: a cabinet that includes at least one storage compartment; a plurality of doors that open and close the at least one storage compartment; a plurality of operating units that are provided at each door; and a door opening apparatus that is positioned at the cabinet and opens one of the plurality of doors corresponding to the operation of the plurality of operating units, wherein the door opening apparatus includes a driving motor, a power transfer unit that transfers power of the driving motor, and a plurality of push members each of which corresponds to the plurality of doors and are connected to the power transfer unit, and when the driving motor is operated, one of the plurality of push members pushes one of the plurality of doors.
Claims18
A refrigerator, comprising:
- a cabinet that includes at least one storage compartment;
- a plurality of doors that open and close the at least one storage compartment;
- a plurality of operating units that are provided at each door;
- and
- a door opening apparatus that is positioned at the cabinet and opens any one of the plurality of doors corresponding to the operation of the plurality of operating units,
- wherein the door opening apparatus includes a driving motor, a power transfer unit that transfers power of the driving motor, a plurality of push members each of which corresponds to the plurality of doors and are connected to the power transfer unit, and a plurality of moving guides that guide the movement of each push member,
- when the driving motor is operated, any one of the plurality of push members pushes any one of the plurality of doors,
- wherein each push member comprises a rack gear and the power transfer unit comprises at least one pinion gear engaged with the rack gear to transfer power of the driving motor to the rack gear,
- wherein at least one of the plurality of push members comprises a plurality of position confirming units that are spaced apart from each other and at least one of the plurality of moving guides comprises at least one sensing unit that senses one or more of the plurality of position confirming units, and
- wherein the power transfer unit comprises a worm gear that is connected to a rotating shaft of the driving motor and a plurality of pinion gears that are rotated based on rotation of the worm gear.
