ABSTRACT:
Disclosed is a refrigerator having a cool air dispersing device capable of dispersing cool air vertically. In a duct of a cooling compartment are installed many vertical dispersing blades of planar plate shape for dispersing cool air flowing thereinto vertically. A vertical shaft is installed in the duct. Many horizontal dispersing blades of planar shape are installed on the shaft. The shaft is rotated by a motor, and a cam is installed on the shaft. The cam converts a rotational movement of the motor to an elevational/de-elevational movement of the vertical dispersing blades. Thus, the cool air is dispersed horizontally and vertically in the compartment, and the temperature in the compartment is maintained uniform. Further, if the blades are stopped, the cool air can be concentrated on a specific area.
