Zusammenfassung:A dishwasher comprising a cabinet that defines an access opening. The dishwasher has a door hingedly mounted to the cabinet and pivotable about a door axis of rotation between a pivotal range between opened and closed positions to selectively open/close the access opening. The dishwasher also has a counterbalance assembly coupled the cabinet to the door. The counterbalance assembly has a guide member with a rotatable pulley that rotates about a pulley axis of rotation and has a fixed radius from the pulley axis of rotation. The guide member also has a varying radius from the pulley. The counterbalance has a force applicator that applies a counter-balancing force to one of the pulley or cam, and the counterbalance has a connector that couples the other of the pulley or cam to the door. The counterbalance force applies a varying counterbalance torque to the door that is a function of the ratio between the fixed radius and the varying radius over the pivotal range of the door.
