Abstract
An appliance lid hinge assembly includes a cam arm pivotally connected a base. A cam arm control system includes a spring rod adapted to move in a sliding reciprocal manner. A spring urges the spring rod toward an extended position. The spring rod is movable toward a retracted position. The cam arm is engaged with the spring rod through a cam follower such that: (i) pivoting movement of the cam arm in an opening direction corresponds with movement of the spring rod from the retracted position toward the extended position; and, (ii) pivoting movement of the cam arm in a closing direction opposite the opening direction corresponds with movement of the spring rod from the extended position toward the retracted position. An optional damper exerts a damping force on the spring rod or other part of the cam arm control system when the cam arm moves in a closing direction.
