  • Door opening/closing apparatus for a washing machine
    Patent number: 5546773
    Abstract: A washing machine has a door mounted for rotation between open and closed positions. An electrical solenoid is connected to the door by means of a wire so that when the wire is pulled by the solenoid, the door is opened from a closed position, or closed from an open position. A torsion spring is connected to the door for storing energy while the door is being opened or closed, and then releasing the stored energy to maintain the door in the open or closed position. The wire is flexible to enable the door to be manually opened without actuating the solenoid.
