COLD AIR CIRCULATING STRUCTURE OF REFRIGERATOR

PROBLEM TO BE SOLVED: To attain a uniform temperature distribution of a refrigerator chamber and a freezer chamber by a method wherein after refrigerant supplied to a storing space is circulated inside the storing space, the cold air in the storing space is guided into a returning passage through a door and further returned back through one side of the storing space. SOLUTION: A door duct 120 is formed in an inner side of a freezer chamber door 110 opening or closing a freezer chamber 100 acting as a storing space over an upward or downward direction of the inner freezer chamber, wherein the door duct 120 is communicated with an inner side of the freezer chamber 100 at an inlet 122 and an outlet so as to constitute a part of the cold air circulating passage inside the freezer chamber 100. Then, after the cold air supplied to the freezer chamber 100 is circulated inside the freezer chamber 100, the cold air is passed through the inlet 122 and the outlet of the door duct 120 and guided to a returning passage 132 and then returned back through one side of the freezer chamber 100. In addition, similarly, the cold air in the refrigerator chamber 200 is guided to the returning passage 136 through a space provided with an inlet 222 and an outlet 224 of a refrigerator chamber door duct 210 is guided to the returning passage 136 and further returned back through one side of the refrigerator chamber 200.
