Abstract
An accelerated cooking feature for use in an appliance having an oven cavity includes a forced air convection system having an electronic control unit, a variable speed, bi-directional fan motor, and a directionally vented cover plate. The appliance operates in at least three modes, constituted by a convection mode, a radiant bake mode and a self-clean mode. In the convection mode, the controller operates the fan motor in a first direction at a speed dependent upon a selected cooking process, with various air streams being directed into distinct regions of the oven cavity. During the radiant bake mode, the controller operates the fan motor in a reverse direction to establish a uniform cooking environment. In the self-clean mode, high speed air currents are directed into the oven cavity and, in combination with a top broil element, perform a pyrolytic cleaning process.
