容量の増大と冷却作用の保持に大きな働きをしている。FIG. 7 shows another conventional example of a fence mounting device.
In this example, the fence 8 is provided with legs 82 bent forward. Then, the fence 8 is installed on the upper surface of the return grill 31 by inclining the fence 8 forward and backward so that the legs 82 are inserted from the holes on the upper surface of the return grill and the leg tips 82a are brought into contact with the rising inner surface of the outer box 2. It In the open showcase, products are stored and displayed on a shelf 41 provided in the compartment 4 and a bottom plate 32 of the inner box 3. Then, the fence 7 circulates the inside air as the cooling air through the cooler 6 and circulates the cooling air.
A cold air curtain 11 is formed in the opening 1a for shielding the interior 4 from the outside air, and the interior 4 is cooled to refrigerate the product. A large amount of products are stored in the interior 4 to enhance the sales efficiency, and sometimes products are stacked on the bottom plate 32 over the upper surface of the return grill 31. In this case, the fence 8 stores the stacked products in the front. It is prevented from rolling or protruding to block the suction port 5b. Therefore, the fence 8 plays a large role in increasing the amount of goods stored in the open showcase and maintaining the cooling effect.
