As shown in these figures, the special storage unit 103 is formed in the upper portion of the refrigerating chamber, the special storage unit 103, the storage container 105 and the storage container 105 that accommodates the storage and slides back and forth, and the storage container 105 And a special storage unit door 110 for opening and closing the front region of the special storage unit 103 in conjunction with the front and rear of the door.

The storage container 105 has a box shape, and the front side and the top side are open to facilitate storage of the stored matter. Guide slopes 106 are provided in front regions of both side walls of the storage container 105.

Hinge shaft receiving grooves 108 are recessed in both side inner walls of the front of the special storage unit 103, and hinge shafts 111 formed at both ends of the special storage unit door 110 in the hinge shaft receiving groove 108. Is combined. A triangular guide jaw 113 is formed on the rear surface of the special storage unit door 110 so as to be in contact with the guide inclined surface 106 of the storage container 105.

By such a configuration, when the storage container 105 is accommodated in the special storage unit 103 and the special storage unit doors 110 are hinged to each other, the special storage unit door 110 is hinged by its own weight. Will be rotated downward on the axis. At this time, the guide jaw 113 formed on the back of the special storage unit door 110 is in contact with the guide inclined surface 106 of the storage container 105.

In the combined state, when the storage container 105 is pulled out and pulled out, the guide jaw 113 of the special storage unit door 110 moves upward along the guide inclined surface 106, and thus the special storage unit. The door 110 is pivoted upward so that the front opening of the special storage unit 103 is opened.

By the way, in the conventional refrigerator, the specially selected storage unit door is gradually opened in conjunction with the withdrawal of the storage container. However, when the storage container is stored in the specially selected storage unit, the specially selected storage unit door is closed by its own weight. At this time, the special storage door and the storage container may have a difference in the relative movement speed, and when the storage container is stored relatively rapidly compared to the special storage, the special storage door is rapidly rotated to collide with the storage container. . In this case, there is a problem that not only causes severe impact noise, but also damages the storage container and the special storage unit door.

It is therefore an object of the present invention to provide a refrigerator which can prevent sudden closure of the specially-stored door and prevent damage caused by impact noise and collision.
