ABSTRACT:
An oven is capable of cooking food in a microwave mode or in a simultaneous microwave/convection mode. During the microwave cooking mode, a first fan blows outside cooling air through an electrical component compartment and then into a cooking chamber via through-holes formed in a partition wall separating the compartment from the cooking chamber. During the simultaneous microwave/convection cooking mode, cooling air is prevented from entering the cooking chamber via the through-holes by an air curtain established across the cooking chamber side of the through-holes. The air curtain is established by a second air circulator which blows heated air into the cooking chamber in a direction toward the through-holes.
