摘要:
A hinge (10) for rotatably coupling an appliance door (12) with an appliance body (16) includes a housing (18) affixable within the door (12). An input arm (20) is rotatably coupled to the housing (18) and is affixable with the appliance body (16). A spring (24) is operably engaged between the housing (18) and the input arm (20) to apply a balancing torque to the input arm (20) relative to the housing (18). A first magnet (26) is fixed relative to the housing (18) and a second magnet (28) is operatively coupled with the input arm (20) such that rotation of the input arm (20) with respect to the housing (18) moves the second magnet (28) axially with respect to the first magnet (26). The magnets have a mutual attraction between each other that is operable to apply a closing torque to the input arm (20) relative to the housing (18). The balancing torque decreases with movement of the input arm (20) from the second position toward the first position.
