Abstract

This invention relates generally to ovens of the type used in household ranges and more particularly to ranges of the selfcleaning or pyrolytic type having a rotisserie using an external drive motor.

Claims

1. A cooking oven chamber including interior walls, an opening in one of said walls, rotisserie drive means on the exterior of said one wall and having driving coupling means engageable through said opening, rotisserie means including a rotatable skewer and frame means to support said skewer for rotation about an axis and to be movable axially to and from said opening, cover means movably mounted on said one wall to normally close said opening, and interengageable cam means on said skewer and said cover defining at least one surface oblique to said axis and operably upon interengagement of said skewer with said cover to cause said cover to move laterally from said axis to uncover said opening upon axial movement of said skewer toward said opening.

2. A cooking oven chamber as set forth in claim 1 wherein said cover means is pivotally mounted one interior wall above said opening and above the center of gravity of said cover.

3. A cooking oven chamber as set forth in claim 1 wherein said cam means includes a laterally sloping surface on said cover and a tapered point on said skewer.

4. A cooking oven chamber as set forth in claim 3 wherein said cam means includes two sloping planar surfaces converging along a generally vertically extending junction line which is in substantial axial alignment with the point on said skewer.

5. A cooking oven chamber as set forth in claim 2 wherein said cover includes a convex surface adapted to interengage said opening to provide detent means tending to resist movement of said cover laterally away from said opening.

6. A closure member for sealing off an opening in a vertical wall of a range oven, which opening provides access to a rotisserie drive motor having means to receive and rotatably drive a rotatable member of a rotisserie, said closure member including means adapted to rotatably mount said closure member for rotation about a horizontal axis above said opening and above the center of gravity of said closure member, said closure member including a sealing face adapted to extend across said opening and making substantial sealing contact with said wall in the area surrounding said opening, said closure member being provided with projecting cam surfaces extending laterally outwardly into the oven and being adapted to cooperate with a cam member on the rotisserie, said cam surfaces including a pair of surfaces sloping laterally together from opposed edges of said closure member to be joined together on a junction line in substantial axial alignment with the vertical centerline of said opening with said junction line sloping upwardly and toward said wall at a point adjacent the means pivotally mounting said closure member, whereby operation of said rotisserie to move said rotisserie into driving engagement with said motor rotates said closure member about said pivot to uncover said opening prior to the making of driving engagement between said rotisserie and said driving motor.
