  • Patent number: 7637119
    Abstract: In the related art refrigerator, its structure for supplying water to a dispenser and water tank was complicated. In addition, since an icemaker is installed in a refrigerating chamber of the refrigerator, there is a problem in that the water supplied into the icemaker is frozen. Furthermore, if the icemaker is installed in the freezing chamber of the refrigerator in which the refrigerating chamber is formed at a lower portion thereof and a refrigerating chamber is formed at an upper portion thereof, there is another problem in that it is difficult to control the temperature in the refrigerating chamber or ice-making capability of the icemaker is lowered. The present invention is directed to a refrigerator.

  • Patent number: 7540169
    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.
