Abstract
A hinge assembly for pivotally connecting an associated appliance lid to an associated appliance body includes a base adapted to be connected to the associated appliance body. The hinge assembly also includes a snubber housing connected to the base. A cam is rotatably supported on the snubber housing, and the cam is adapted to be engaged by the associated appliance lid and rotate about a lid pivot axis in a first direction and in a second direction that is opposite the first direction. A snubber is operatively connected to the snubber housing. The cam exerts a snubber activation force on the snubber when the cam rotates about the lid pivot axis in the second direction corresponding to movement of the associated appliance lid from an opened position toward a closed position and such that the snubber damps movement of the cam when the cam rotates in the second direction. A counterbalance spring is operatively engaged between the base and the cam and exerts a counterbalance force on the cam that biases the cam in the first direction.
