The opening 7 is formed between the bottom surface 71 and the bottom surface 71 provided with the uneven ribs 77 on the upper surface that is connected to the walls other than the uneven wall 38.
4 is provided. On the ribs 76 and 77, an aluminum dish 78 for placing items is placed. The cold air in the container 34 can flow downward along the inner surface of the uneven wall 38 as indicated by the arrow even when many items are placed on the dish 78, and after flowing downward, The door 31 (not shown) flows out from the opening 74 and goes downward.
I tried not to go near the opening. Cold air is bottom 7
0 between the ribs 76 between the tray 78 and a portion of the ribs 77 between the bottom 71 and the tray 78, so that the items placed on the tray 78 can be efficiently processed. Can cool well. Since the bottom portion 70 extends the required length (l) in the direction opposite to the door 31 (not shown), cold air does not hit the tip of the heated receiving portion 13 (not shown). In this way, the energy saving effect can be improved.

The refrigerator of the present invention is designed not to have a cold air hole at the upper end of the container so that the cool air in the container does not flow between the door and the inner surface of the wall of the container facing the door. Are formed in an uneven shape, the cool air in the container is caused to flow downward along the inner surface of the uneven wall, and the cool air flowing downward is discharged in a specific direction from a specific opening formed at the bottom of the container. By doing so, the items in the container can be efficiently cooled and a high energy saving effect can be achieved. Further, since the space for circulating the cool air is not required between the container and the door, the container can be made large and the effective internal volume can be made large.
