Abstract

An oven comprises a cooking chamber, first and second energy sources, a cooling fan, and a controller. The first energy source provides radiation heating in the cooking chamber, and the first energy source has a low mass for rapid heating. The second energy source provides convection heating in the cooking chamber, and the second energy source has a high mass heating element and a convection fan for moving air through the cooking chamber during convection heating. The cooling fan moves cooling air over the first energy source. The controller energizes the first and second energy sources during at least initial convection heating so that the first energy source rapidly heats the cooking chamber in order to facilitate the initial convection heating and to eliminate the need to pre-heat the cooking chamber.
