Patent ID: 7509998

Claim:
A device for modifying the temperature of bedding comprising a bed cover, said device comprising: a housing having an exterior and an interior, said housing defining an air intake, an air plenum and an air outlet; a fan mounted in said housing for moving air in said air intake, through said plenum and out said air outlet; a heat transfer element mounted within said housing for modifying the temperature of the air entering said air intake; a temperature sensor mounted in said plenum for sensing the temperature of the air moving through said plenum; a control circuit connected to said temperature sensor, said control circuit being operative to maintain the temperature of air moving through said plenum at or below a selected temperature; a timer mounted within said housing, said timer being operative to activate said fan and heat transfer element either immediately or at any specified time within a twenty-four hour period upon being turned on or set by means of either a timer dial or a plurality of pushbuttons and a display panel and to deactivate said fan and heat transfer element after a selected amount of time; and an elongated air delivery section having two ends and defining an air entrance at one end, a primary air exit at the other end and a plurality of secondary air exits adjacent to the other end, said air entrance being adapted to connect to said air outlet; wherein said elongated air delivery section has a longitudinal axis and comprises a flattened portion; wherein said elongated air delivery section comprises means for suspending an aromatic element in and introducing an aromatic substance into the air moving through said elongated air delivery section such that said air is modified or further conditioned by said elements; wherein said primary air exit is situated at the terminus of said flattened portion and is adapted to discharge air substantially parallel to said longitudinal axis and far enough beneath a bed cover to cause the bedding to inflate; and wherein said plurality of secondary air exits are situated within said flattened portion and are adapted to discharge air substantially perpendicular to said longitudinal axis.
