A convection and radiant heated oven has a cooking chamber and an air heating chamber below and spaced from the cooking chamber. Shield means above the heating chamber defines, with the oven bottom, a heat space in which an apertured duct receives heated air from the heating chamber and conducts it to a convection fan where it mixes with air from the cooking chamber and is ducted into the cooking chamber. Heated air is also passed upward from the heat space directly into the cooking chamber.

Why it's free to use
- Filed January 8, 1992 and granted August 2, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 8, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 8, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
