PURPOSE:To expand the size of each of a cooling device or a fan with a similar space as that of a prior art and improve a freezing capability by a method wherein a centrifugal fan and a guide are disposed within a cold air duct and an air blowing outlet is positioned more downwardly than the center shaft of the fan. CONSTITUTION:A rear vertical partition wall A5 defines a cooling chamber 22 and a freezing chamber 2 and the partition wall is located more forwardly than a cooling device 4. A guide 8 is formed by each of ribs of the partition wall A5 and a forward partition wall B7, a clearance in a circumferential direction of a centrifugal fan 6 becomes maximum at an air blowing outlet port and the clearance is decreased as it goes along a circumference of the fan 6 and it has a scroll shape in which the air blowing outlet is positioned more downwardly than a rotary central shaft of the fan 6. The centrifugal fan 6 and the guide 8 are disposed more forwardly than that of the partition wall A5 so as to reduce a restriction in size toward a downward direction of the fan 6 and the guide 8. The air blowing outlet of the guide 8 is disposed more downwardly than the rotary central shaft of the fan to expand the sizes of the cooling device 4 and the fan 6 upwardly. |
