The bottom region of the refrigerating compartment may accommodate vegetables and fruits. The vegetable chamber 115 is provided.

Each inner plate surface of the freezing chamber door 107 and the refrigerating chamber door 109 is provided with a plurality of door baskets 111 and 113 spaced apart from each other along the vertical direction to accommodate food.

However, in such a conventional refrigerator, when the quantity of packs such as alcoholic beverages, beverages or milk, etc. stored in the door basket 113 of the refrigerating chamber 105 is large, the height of the pack is stored in the refrigerating chamber 105. Because they can't stand, they are stored separately. At this time, the co-current product has a problem in that it is difficult to use due to structural difficulty in lamination and rolling along the bottom surface.

In addition, the interior space of the refrigerating chamber is to store and store the goods in a space partitioned by a plurality of shelves 108 spaced apart from each other along the vertical direction, so that the lower height actually has a relatively large floor area compared to the volume. They will occupy their upper spaces, or they will be stacked with other low-level objects. Thus, in the conventional refrigerator, there is a problem in that space utilization is insufficient when the height of the object is low, and when the objects are stacked and stored, it is difficult to withdraw and store the object.

Accordingly, an object of the present invention is to provide a refrigerator having a double door that can increase the storage space of the door and efficiently utilize the internal space.
