Abstract: A refrigerator appliance may include a cabinet, a door, a door opener, and a controller. The door opener may be attached to a cabinet and include a casing, a push rod, and a position sensor. The controller may be in operable communication with the door opener and configured to direct an opener operation. The opener operation may include directing the push rod to a retracted position, detecting the door in the closed position following directing the push rod to the retracted position, directing the push rod forward from the retracted position following detecting the door in the closed position, monitoring sensor output at the rod-load sensor while directing the push rod forward, detecting contact with the door while monitoring sensor output, and halting the push rod at a partially extended position in response to detecting contact.

Abstract: A domestic appliance may include a cabinet, a door, and a linear hinge coupling the door to the cabinet. The linear hinge may include a bearing assembly, an elongated shaft, a door linkage, and a cabinet linkage. The bearing assembly may be mounted to the cabinet. The elongated shaft may be received within the bearing assembly and slidable along a translation axis on the bearing assembly. The elongated shaft may define a first shaft pivot axis perpendicular to the translation axis and a second shaft pivot axis parallel to the first shaft pivot axis. The door linkage may couple the door to the elongated shaft. The door linkage may be pivotally connected to the elongated shaft at the first shaft pivot axis. The cabinet linkage may couple the cabinet to the elongated shaft. The cabinet linkage may be pivotally connected to the elongated shaft at the second shaft pivot axis.

Abstract: A refrigerator appliance includes a cabinet defining a food storage chamber. A door is positioned on the cabinet and is movable between a closed position and an open position. A door opener includes a casing, a gear box, a sliding nut movable relative to the gear box, and a finger extending through the gear box. The finger is movable with the sliding nut. The door opener also includes a sensor. The finger extends outside of the casing to contact an inner surface of the door when the door is in the closed position and the door opener is in a zero position. The sensor is configured to detect movement of the door opener from the zero position.
