Claims (6)

In a refrigerator that has a drive unit with a motor and closes the door in an open state with respect to the main body by driving the motor,
Wherein the drive unit is provided with an output shaft that rotates attached to the body,
The output shaft is connected to the door via a link mechanism comprising a lever coupled to the output shaft and at least one connecting member having a connecting point rotatable at both ends;
As the range up to the drive unit from the link mechanism within the thickness of the movement locus of the door,
Refrigerator, characterized in that a closable by the motor driving the door to the fully closed position from the 90 ° or more fully open position. The case of the drive unit has an arc peripheral wall centered on the output shaft as seen from above,
2. The refrigerator according to claim 1, wherein the connecting member having one end connected to the lever is bent along the circular arc wall as viewed from above and overlaps the circular arc wall as viewed from a radial direction. Wherein the link mechanism, has a plurality of said connecting member including a final stage coupling member connected to the first-stage coupling member and the door is coupled to the lever,
The refrigerator according to claim 1 or 2, characterized in that a closable by the motor driven to the fully closed position from the fully open position beyond a 90 ° to the door. The door, the connection point of the last stage connecting member and its front connecting member, so as to be separated from the line connecting the rotation axis of the door and the connecting point of the first-stage coupling member and the lever, the last stage connected The refrigerator according to claim 3, wherein a first restricting portion for restricting a rotation range of the member is provided. Between the first-stage coupling member and the lever, when the connecting point of the with the lever stage connecting member across the center of rotation of said lever is on the opposite side of the connecting point of the door and the last stage connecting member, wherein that is provided with a second regulating portion for separating the connecting point of the first-stage coupling member and its next stage coupling member from the extension of the line connecting the connection point of the door with the center of rotation of the lever and the last stage connecting member The refrigerator according to claim 3 or 4, characterized by the above. Said door is provided with a third regulating portion for rotating the final-stage coupling member abuts the last stage connecting member when rotating the door in the closing direction without the motor drive integrally with the door,
The link mechanism includes a relative rotation angle at each connection point so that connection points between the connection members and between the lever and the first-stage connection member do not cross a straight line connecting connection points on both sides of the connection point. The refrigerator according to any one of claims 3 to 5, further comprising a fourth restricting portion that restricts the temperature.
