Abstract
An oven includes an oven cavity, at least one heat source disposed in the cavity; and only one reversible fan disposed in the cavity, the fan is configured to change an airflow pattern in the cavity by reversing a direction of rotation.
Claims32
An oven comprising:
- an oven cavity;
- at least one heat source for supplying energy to said cavity;
- and
- only one reversible fan assembly, said assembly comprising a reversible motor, a shaft extending from said motor, and a fan coupled to said shaft, said fan assembly operable to change an airflow pattern in said cavity by reversing a direction of rotation of said.
