Cool air circulating apparatus for a refrigerator

摘要

A refrigerator has freezing and refrigerating compartments arranged above and below one another. A hollow duct extends vertically through said freezing and refrigerating compartments and receives a flow of cool air at its upper end. The duct includes vertically spaced holes through which the cool air is discharged into the freezing and refrigerating compartments. The duct is freely rotatable about its longitudinal axis and carries fins arranged at the discharge holes such that the discharging cool air impinges against the fins to cause the duct to rotate.
