ABSTRACT:
A cold air supply and control device for a refrigerator is provided. The cold air supply and control device includes a cylindrical, duct main body having an inlet that allows cold air generated in a heat exchange chamber to be introduced thereinto and an outlet that supplies the cold air introduced through the inlet to a refrigerating chamber. The duct main body is pivotably installed to at least one of both side surfaces of the refrigerating chamber. An opening and closing piece is fixed to the side surface of the refrigerating chamber and selectively opens and closes the outlet according to a rotation of the duct main body. An interlocking plate formed below the outlet of the duct main body rotates the duct main body by a load of a shelf so as to open the outlet. In addition, a torsion spring is installed between a surface of the refrigerating chamber and a front or rear surface of the duct main body, and elastically supports the duct main body in a direction in which the outlet is closed.
