Abstract
A bladeless ceiling fan is provided. The bladeless ceiling fan includes a housing configured to accommodate an electric motor. The housing can define one or more vents through which air enters an interior of the housing. The bladeless ceiling fan can further include an airfoil defining an interior passage. In addition, the bladeless ceiling fan includes one or more conduits. The one or more conduits extend from the housing to the airfoil such that air within the interior of the housing flows through the one or more conduits and into the interior passage defined by the airfoil.
