Oven appliance with dual opening and closing doors

摘要

An oven appliance includes a cabinet that defines a chamber. A pair of doors is rotatably mounted to provide selective access to the chamber of the cabinet. The pair of doors is connected with a linkage assembly such that the doors rotate open and closed simultaneously. The linkage assembly includes a spur gear that engages another gear of the linkage assembly. The spur gear can hinder unwanted rotation of the pair of doors or compress the pair of doors against a seal.

1. An appliance, comprising:
a cabinet defining a chamber, the cabinet also defining an opening, the chamber of the cabinet being accessible through the opening of the cabinet; a first door rotatably mounted proximate the opening of the cabinet; a second door rotatably mounted proximate the opening of the cabinet, the first and second doors rotatable between an open position and a closed position in order to permit selective access to the chamber of the cabinet through the opening of the cabinet; and a linkage assembly coupling the first door and the second door such that the first and second doors rotate between the open position and the closed position simultaneously, the linkage assembly comprising:
a first linkage arm extending between a first end and a second end, the first end of the first linkage arm connected to the first door;a first gear having an outer edge and a plurality of teeth disposed on an engagement edge of the first gear, the second end of the first linkage arm connected to the first gear, the engagement edge of the first gear forming only a portion of the outer edge of the first gear and positioned opposite the second end of the first linkage arm on the first gear;a second gear having a plurality of teeth disposed on an engagement edge of the second gear, the plurality of teeth of the second gear meshing with the plurality of teeth of the first gear;a second linkage arm extending between a first end and a second end, the first end of the second linkage arm connected to the second door, the second end of the second linkage arm connected to the second gear, the engagement edge of the second gear positioned opposite the second end of the second linkage arm on the second gear;a spur gear having a plurality of teeth, the plurality of teeth of the first gear positioned on the first gear such that the plurality of teeth of the spur gear engage the plurality of teeth of the first gear at the engagement edge of the first gear when the first door is in the closed position and the plurality of teeth of the spur gear do not engage the plurality of teeth of the first gear when the first door is in the open position, the engagement edge of the first gear facing away from the spur gear when the first door is in the open position; anda biasing member coupled to spur gear, the biasing member urging the plurality of teeth of the spur gear against the plurality of teeth of the first gear when the first door is in the closed position in order to urge the first door to remain in the closed position.
