Oven appliance with dual opening doors
The present subject matter provides an oven appliance. The oven appliance includes a pair of doors. A pair of sprockets or gears, a pair of chains, and a pair of connecting members couple the doors to each other such that the doors open and close simultaneously. The oven appliance also includes features for limiting or eliminating contact between the connecting members at a location where the connecting members cross each other.
1. An oven appliance, comprising:
a cabinet defining a chamber for receipt of food items for cooking, the chamber being accessible through an opening defined by the cabinet;
a heating element for providing heat to food items within the chamber of the cabinet;
a pair of doors mounted proximate the opening, each door of the pair of doors having an axis of rotation about which the door is rotatable so as to open or close access to the chamber of the cabinet through the opening of the cabinet;
a pair of sprockets, each sprocket of the pair of sprockets connected with a respective door of the pair of doors and positioned along the axis of rotation of the door so as to rotate with the door;
a pair of chains, each chain of the pair of chains meshing with a respective sprocket of the pair of sprockets;
a pair of connecting members extending between and connecting the chains of the pair of chains such that rotational motion is transferred between the pair of doors; and
a cross-block positioned between the connecting members at a location where the connecting members cross each other, the cross-block defining a first channel and a second channel, the first and second channels of the cross-block positioned on opposite sides of the cross-block relative to each other, a first one of the connecting members positioned within the first channel of the cross-block and a second one of the connecting members positioned within the second channel of the cross-block such that the cross-block is positioned between the first and second ones of the connecting members.
2. The oven appliance of claim 1 , wherein the cross-block is mounted to the cabinet.
3. The oven appliance of claim 1 , further comprising a sleeve positioned on a first one of the connecting members.
4. The oven appliance of claim 3 , wherein the sleeve is constructed with a plastic.
5. The oven appliance of claim 1 , further comprising a spacer block mounted to the cabinet and engaging a first one of the connecting members in order to urge the first one of the connecting members away from a second one of the connecting members.
6. The oven appliance of claim 5 , wherein the spacer block is positioned proximate one of the pair of sprockets.
7. The oven appliance of claim 1 , wherein each connecting member of the pair of connecting members extends between a first end portion and a second end portion, each connecting member of the pair of connecting members also defining a substantially flat face between about the first end portion of the connecting member and about the second end portion of the connecting member, the substantially flat faces of the connecting members facing each other at the location where the connecting members cross each other.
8. The oven appliance of claim 1 , wherein a first one of the connecting members is constructed with a first material and a second one of the connecting members is constructed with a second material, the first material having a hardness that is less than a hardness of the second material.
9. The oven appliance of claim 1 , wherein the cross-block is positioned above a gap defined between the doors of the pair of doors.
10. The oven appliance of claim 1 , wherein the connecting members of the pair of connecting members and the chains of the pair of chains are connected together in a figure-eight shape.
11. The oven appliance of claim 1 , wherein the cross-block is constructed with a plastic.
12. The oven appliance of claim 11 , wherein the connecting members are constructed with a metal.
13. An oven appliance, comprising:
a cabinet defining a chamber for receipt of food items for cooking, the chamber being accessible through an opening defined by the cabinet;
a heating element for providing heat to food items within the chamber of the cabinet;
a pair of doors mounted proximate the opening, each door of the pair of doors having an axis of rotation about which the door is rotatable so as to open or close access to the chamber of the cabinet through the opening of the cabinet;
a pair of sprockets, each sprocket of the pair of sprockets connected with a respective door of the pair of doors and positioned along the axis of rotation of the door so as to rotate with the door;
a pair of chains, each chain of the pair of chains meshing with a respective sprocket of the pair of sprockets;
a pair of connecting members extending between and connecting the chains of the pair of chains such that rotational motion is transferred between the pair of doors; and
a cross-block mounted to the cabinet and positioned between the connecting members at a location where the connecting members cross each other, the cross-block defining a first channel and a second channel, the first and second channels of the cross-block positioned on opposite sides of the cross-block relative to each other, a first one of the connecting members positioned within the first channel of the cross-block and a second one of the connecting members positioned within the second channel of the cross-block such that the cross-block is positioned between the first and second ones of the connecting members at the location where the connecting members cross each other.
14. The oven appliance of claim 13 , wherein the cross-block is constructed with a plastic.
15. The oven appliance of claim 14 , wherein the connecting members are constructed with a metal.
16. The oven appliance of claim 13 , wherein the cross-block is positioned above a gap defined between the doors of the pair of doors.
17. The oven appliance of claim 13 , wherein the connecting members of the pair of connecting members and the chains of the pair of chains are connected together in a figure-eight shape.
