Abstract
A combination microwave and air impingement oven has two magnetrons and an air handling system that includes two or more reciprocating ducts through which air is dispensed into the oven. The rotating ducts are configured to stir microwave energy in the oven to prevent formation of hot spots and to sweep microwave radiation over the surface of the food product. A foraminous partition, configured to encircle a portion of the cooking chamber, has a central portion and extremities mounted to divide the interior of the cabinet into a cooking chamber and an air heating chamber. The partition extends around a major part of the periphery of the cooking chamber such that air is drawn along multiple paths toward side walls and toward the rear wall from the cooking chamber.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
