  • Patent number: 9273892
    Abstract: Disclosed is an icemaker for a refrigerator, comprising: a tray for containing water to make the water into ice pieces having a predetermined shape; a water supply unit installed at one side of the tray, for supplying water to the tray; a drive unit installed to face the water supply unit with the tray being interposed therebetween; an ice separating lever rotatably assembled between the drive unit and the water supply unit to be rotated by a motor installed in the drive unit; and an ice separating heater for applying heat to the tray so that ice pieces are separated from the tray. The drive unit includes a drive unit housing, a driving motor having a driving gear, a slave gear having a rotary cam and a first magnet and coupled to a rotary shaft of the ice separating lever, a cantilever having a second magnet and rotated by the rotary cam, and first and second Hall elements corresponding to the first and second magnets, respectively.

  • Patent number: 6058734
    Abstract: A refrigerator has a freezer compartment, a refrigerating compartment, and an evaporator. The refrigerator further has a first bypass passage, a second bypass passage and a cooled air inducing pipe.The first bypass passage allows the cooled air from the refrigerating compartment to flow directly to a fan of the refrigerating compartment, thereby allowing the cooled air to bypass the evaporator.The second bypass passage allows the cooled air from the freezer compartment to flow directly to a fan of the freezer compartment, thereby allowing the cooled air to bypass the evaporator.The cooled air inducing pipe mounted in front of the fan changes the direction of the cooled air and force the cooled air to the refrigerating compartment.
