  • Ice maker with a motor having gears with means to intermittently rotate a gear thereof
    Patent number: 6276160
    Abstract: A motor having gears which transmit rotations of a rotor to an output shaft through a gear mechanism made of gear trains, comprises a gear mechanism provided with an intermittent rotation mechanism including a primary gear which rotates upon receiving rotations of the rotor and a secondary gear which meshes with the primary gear and rotates intermittently. The primary gear has a tooth unit for driving the secondary gear, a tooth-shaped hole, which is provided adjacent to one side of the tooth unit and with which a meshing tooth of the secondary gear meshes, and a control unit which is provided adjacent to the other side of the tooth unit so as to stop the secondary gear for a given period such that the primary gear is asymmetric around the tooth unit. When the primary gear rotates in a predetermined direction, the meshing tooth meshes with the tooth-shaped hole to intermittently rotate the secondary gear.
