Oven debris collection system

1. An oven debris collection system configured to be mounted to an oven with a housing, cooking chamber, cooking surface and a doorway, the oven debris collection system comprising:

a frame configured to be mounted to the exterior of an oven;

a shelf panel attached to the frame;

the shelf panel having and having an upper surface substantially contiguous with the cooking surface;

the shelf panel comprising perforations through which food debris may pass; and

at least one removable debris tray removably attached to the frame below the shelf panel to catch and retain the debris passing through the perforations.

2. The oven debris collection system as recited in claim 1 and further comprising an open region transversely outward of the shelf panel relative to the doorway through which debris may pass into the debris tray.

3. The oven debris collection system as recited in claim 1 , the debris tray further comprising a front panel having an upper edge laterally even with the upper surface of the shelf panel.

4. The oven debris collection system as recited in claim 1 , wherein the shelf panel comprises:

a protrusion extending substantially the longitudinal width of the shelf panel; and

the protrusion extends transversely past the frame into the oven.

5. The oven debris collection system as recited in claim 1 , the debris tray further comprising a locking system comprising at least one protrusion extending into a surface defining a hole in the frame.

6. The oven debris collection system as recited in claim 1 , each at least one protrusion extending into a surface defining a hole in the frame comprises a protrusion and a cutout which allows the protrusion to drop downward into the hole and thus hold the debris tray in pace against the frame until the debris tray is lifted and removed from the frame.
