Abstract
A counterbalance assembly for an appliance hinge has a base including first and second spaced-apart side walls and a transverse face wall. A channel is located between the first and second side walls. First and second notch portions are respectively located in the first and second side walls. A rotating cam is supported on the base and has a camshaft that extends between the side walls and that is adapted for rotation about an axis of rotation, a first end located in the first notch portion and a second end located in the second notch portion. A biasing spring has an inner end engaged with the base and an outer end spaced from the base. A spring rod includes an outer end operatively coupled to the spring and an inner end operatively coupled to the lever. The lever also pivotally connects to the lobe of the cam. A damper assembly is connected to the base and having a piston which is moved between a first position and a second position by the lever contacting the piston. The piston in turn compresses fluid in the damper assembly thus dampening movement of the lid hinge.
