ABSTRACT:
A door opening and closing device for a refrigerator includes plural doors for opening and closing a refrigerator main body; a hinge unit for connecting the corresponding door to the refrigerant main body so that the door can perform rotational motion or translational motion against the refrigerant main body; first interference units provided between the corresponding door and the refrigerant main body, and contacting from a state in which the door is closed to a state in which the door is opened to a designated angle for separating the doors; and second interference units provided between the corresponding door and the refrigerant main body, and contacting from the state in which the door is opened above the designated angle for separating the doors. The door opening and closing device reduces noise and impact generated by the opening and closing of the doors, allowing a user to open and close the doors more softly and smoothly.
