Abstract
A combination convection and radiant cooking appliance includes an oven cavity, broil and bake radiant heating elements, a convection cover defining a rear wall of the oven cavity, a back panel, and a dual fan convection heating system mounted between the convection cover and the back panel. Each combination fan/heater of the dual convection heating system includes a multi-speed fan and an associated electric heating element, with the fans being vertically disposed in the oven cavity. Controls are provided to enable a user to select between at least a bake mode, a no preheat convection bake mode, a rapid preheat convection bake mode, a preheat convection bake mode and a convection roast mode.
Claims15
A cooking appliance comprising:
- a cabinet defining an oven cavity;
- a door attached to said cabinet for selectively exposing and sealing the oven cavity;
- a broil element mounted to the cabinet for heating the oven cavity;
- a bake element mounted to the cabinet for heating the oven cavity;
- a convection heating system including:
- a convection cover including first and second vertically spaced apertures and first and second sets of laterally spaced openings, said convection cover being mounted to the cabinet and defining a rear wall of the oven cavity;
- a back panel mounted to the cabinet behind the convection cover;
- a first convection fan assembly including a motor portion, positioned between the convection cover and the back panel, and a first convection fan positioned at the first aperture;
- a second convection fan assembly including a motor portion, positioned between the convection cover and the back panel, and a second convection fan positioned at the second aperture such that the first and second convection fans are vertically disposed in the oven cavity;
- at least one convection heater extending about both the first and second motor driven fans between the back panel and the convection cover;
- and
- a second convection heater extending about the second motor driven fan between the back panel and the convection cover;
- a user interface enabling a user to select between at least a bake mode, a no preheat convection bake mode, a rapid preheat convection bake mode, a preheat convection bake mode and a convection roast mode;
- and
- a controller in communication with the user interface device for controlling the operation of the broil element, the bake element, the at least one convection heater, and the first and second convection fans.
