<P>PROBLEM TO BE SOLVED: To reduce a pressure loss of a cooling fan, in a refrigerator which circulates cold air generated at a cooler via a duct by the cooling fan into a storage room. <P>SOLUTION: A refrigerator includes: a cooler 4 which is accommodated on the back surface of a storage room 3, and a cooling fan 5 which circulates cold air generated by the cooler 4 into the storage room 3, and further provided with a duct 10 which has a flow adjustment part 11 protruding to the cooling fan 5 side at a position facing the cooling fan 5. Moreover, the flow adjustment part 11 has an approximately-truncated cone shape having a slope 12 and a flat section 13. Consequently, it is possible to reduce a pressure loss on the blowoff side of the cooling fan 5 without increasing a pressure loss on the suction side thereof while suppressing the depth dimension of the duct 10, and furthermore, it is possible to provide the refrigerator with high housing efficiency and cooling efficiency and low noise. <P>COPYRIGHT: (C)2013,JPO&INPIT |
