Abstract
Disclosed is a refrigerator having a device for opening/closing cool air discharge ports through which cool air is supplied into a cooling compartment. In a cool air duct are installed shutter members for opening/closing the ports. The shutter members are installed a positions opening the ports, and are driven by a cam rotated by a motor. The ports and the shutter members are disposed symmetrically around the cam. As the cam rotates, the shutter members close the ports in turn. When a specific area becomes a desired temperature, a port corresponding to the specific area is closed by the shutter members. Thus, the area in the compartment to which cool air is supplied can be regulated, and the overcooling of the compartment can be prevented.
