PURPOSE:To obtain a fan for cold air circulation enabling attainment of low noise and low vibration and also to obtain a freezer-refrigerator which is excellent in fundamental performances such as a cooling force and power-saving and has a large effective internal volume. CONSTITUTION:This freezer-refrigerator is equipped with a cooler 6 disposed below the suction side of a centrifugal fan, a spiral casing 9 provided around the fan, a cold air delivering duct 17 communicating with the discharge side of this casing and an outlet grille 13a. The blade 8a of the centrifugal fan 8 is made a radial blade of which the section is so shaped as to be recessed in the shape of an arc oppositely to the direction of rotation, of which the fitting angle is tilted rearward also oppositely to the direction of rotation and of which the outer peripheral end is in a radial direction substantially. Besides, the centrifugal fan 8 having this radial blade and the spiral casing 9 are juxtaposed at the hack of a storage chamber in such a manner that a suction port 9b of the spiral casing 9 is directed frontward and that they are positioned vertically to the cooler 6 so that they are within the depth dimension of the cooler 6. |
