ABSTRACT:
A bidirectional opening/closing door unit and a refrigerator having the same. The door unit is provided at a side of a body of the refrigerator to open or close the body. The body includes hinges protruding from left and right sides of the body to be coupled with the door unit. The door unit includes a door and an opening/closing device provided at a side of the door. The opening/closing device includes a pair of opening/closing structures detachable to the respective hinges, and an operative connector to be operatively connected to one of the opening/closing structures to limit operation of the other opening/closing structure. With this configuration, the operative connector can achieve smooth movements and maintain a high durability in spite of frequency opening/closing operations and long time use of the door.
