PURPOSE:To eliminate nonuniformity of temperature distribution within a refrigerator and improve strength of ducts acting as an inner box by a method wherein an air passage constructed of the inner box and the ducts is divided along a flow of cold air and is further constructed of a regulating flow fixed plate fixed by both inner box and the ducts. CONSTITUTION:Ducts 19 are arranged within an inner box 6 with a specified spacing so as to constitute an air passage 20. Flow regulating fixed plates 21 are arranged along a flow of cold air at each of the planes of the air passage 20 and then they are contacted with the surface of the inner box 6 and the surface of the duct 19 and fixed at their both sides. Cold air cooled by an evaporator 12 is discharged by a cooling fan 14 and as the air passes through the air passage 20, the air is guided to the right side surface without being short circuited by the flow regulating fixed plates 21 at the top surface and the deep surface, the air passes through the lower deep surface part and again the air is sucked into the evaporator 12. Due to this fact, the cold air uniformly passes through the air passage to cool the duct 19, then an interior of the refrigerator is uniformly cooled and at the same time the flow regulating fixed plates 21 can fix the inner box 6 and the duct 19 in a long range at each of the surfaces, resulting in that a strength of the ducts 19 acting as the inner box can be increased. |
