Convection oven

摘要

A convection oven includes a frame having a base member and two upright members which extend upwardly from the base member. A cooking chamber is removably supported by the frame and includes an upper enclosure member and a lower enclosure member. A housing attached to the upper enclosure member is configured so that cool air flows from a peripheral portion of an arm into a central portion of the housing and then is expelled from the arm over the upper surface of the upper enclosure member. A passive hinge connects the housing to the frame such that the housing and upper enclosure member may be both separated from the frame and lower enclosure member by lifting the housing vertically and pivoted relative to the frame and lower enclosure member. An extension ring selectively enlarges the size of the cooking chamber. A holster may hold the upper enclosure member and the housing when they are separated from the lower enclosure member. In one embodiment, an axial-type hot-air fan guides the hot air in a substantially axial direction within the cooking chamber, and a fan shroud surrounds the hot-air fan so that a radial component of the hot air is initially routed in a substantially axial direction off of the hot-air fan into the cooking chamber of the oven.
