Both the left and right door knobs make it possible to open and shut the refrigerator door by using left/right door hinges and the door knobs. In the door system, brackets (1,2) are installed in left, right, upper, lower position and a gap between doors in order to support hinge rods (5,6). The hinge rods are moved up and down along screws (5a,6a) movably connected to a rack (3), a rotation member (7) , and a gear (7a). If a lever (9) is pulled, a spring (11) connected to the rack is compressed, gear devices being operated, and so hinge rods (5,6) being inserted into bracket holes.
