PURPOSE:To receive obstacles dropped above an air suction port with a grill plate and prevent the obstacles from being dropped into a cold air circulation passage by a method wherein the grill plate at the air suction port is formed to have a sectional passage of Z-shape and then a vertical part of the Z-shaped part is opened as an aeration hole. CONSTITUTION:Refrigerator air passes from a ventilation port 7a through a suction port 5b and is sucked into a cold air circulation passage 5. The air becomes cooling air and is circulated within the refrigerator to cool an inside part of it. In turn, in the case that some obstacles are dropped between a transparent plate 8 and a fence 9, the obstacles are received at horizontal portions 7c and 7d of a grill plate 7 and are prevented from being dropped into a cold air circulation passage 5. Since the obstacles which are easily rolled are prevented from passing through the aeration hole 7a by a raising part 7e, the obstacles do not hurt a cooling device. In addition, the obstacles on the horizontal portions 7c and 7d can be easily removed by removing the fence 9. |
