  • Patent number: 12235032
    Abstract: In a refrigerator, a cam of a cam gear rotating by a driving motor is provided with a structure protruding from an edge portion of a cam gear to a center, thereby increasing the thickness of a cam surface. Therefore, it is possible to reduce the magnitude of force directly transferred from the cam gear to a magnet lever.
    Type: Grant
    Filed: September 11, 2023
    Date of Patent: February 25, 2025
    Assignee: LG Electronics Inc.

  • Patent number: 11774158
    Abstract: An ice making assembly includes: an ice maker configured to make ice, an ice bin that has a portion disposed below the ice maker and that is configured to receive the ice from the ice maker, a detection lever that is disposed below the ice maker and that is configured to rotate to thereby detect a volume of the ice in the ice bin, and a driver configured to rotate the ice maker along a moving path between (i) an ice making position at which ice making is performed and (ii) an ice separating position at which ice separation is performed. The detection lever is configured to detect the volume of the ice in the ice bin being full before and after the ice is separated from the ice maker.
