ABSTRACT:
Disclosed is a refrigerator having a device for dispersing cool air in a cooling compartment. A duct having cool air discharge ports is formed in an inner wall of the compartment. In the duct are installed a horizontal-dispersing blade disposed along a vertical rotational shaft, and a vertical-dispersing blade capable of rotating with respect to a horizontal axis. A worm gear in installed on the shaft, and a worm wheel engaged with the worm gear is installed on the vertical-dispersing blade. As the shaft is rotated by a motor, the blades rotate. Thus, the cool air is uniformly dispersed in the compartment, and the temperature in the compartment is maintained uniform. The angular position of the blades are controlled independently of each other substantially, so concentrative cooling can be performed easily.
