Abstract
One embodiment of the disclosure relates to a heated food container including an interior chamber with an upper portion, a lower portion, and a wall defining an opening into the interior chamber. The opening is configured to permit the movement of food into and/or out of the interior chamber. The heated food container further includes a fan configured to supply air to a duct system and a heater configured to heat the air in the duct system. The duct system includes a first air duct configured to direct the heated air across the opening such that the heated air forms a barrier between the interior chamber and an exterior environment and a first bypass duct configured to deliver heated air directly to the lower portion of the interior chamber without being directed across the opening.
