Oven door opening magnetic hinge

摘要

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

1. A hinge for rotatably coupling an appliance door with an appliance body, comprising:
an input arm affixable with the body; a housing affixable within the door and coupled with the input arm so as to be rotatable through a range of motion between a closed position and an open position; a spring engaged between the housing and the input arm and deformable to apply a balancing torque to the housing relative to the input arm; a first magnet fixed relative to the housing; a second magnet movably received within the housing and operatively coupled with the input arm so as to be positioned adjacent the first magnet when the housing is in the closed position and moved away from the first magnet by rotation of the housing with respect to the input arm from the closed position toward the open position; wherein a mutual attraction between the first and second magnets applies a closing torque to the housing relative to the input arm when the housing is within about 25 degrees from the closed position.
