Abstract: An oven (1000) having a body (1002) that includes a base, a ceiling, and side walls extending between the base and the ceiling, the side walls at least partly surrounding a cooking cavity (1030), the oven (1000) including: an impeller assembly (1060) mounted to a first side wall of the oven body, the impeller assembly (1060) including: an impeller (1062) that is rotatable to direct air flow within the cooking cavity (1030); a plurality of air guides (2006) that at least partially surround the impeller (1062), the air guides (2006) each defining a channel that extends generally transversely from a central axis of the impeller (1062); and a pair of heating elements (2010) located on either side of the impeller (1062), whereby air that is directed from the impeller (1062) travels transversely along the channels of the air guides (2006), across the heating elements (2010), and into the cooking cavity (1030).
