Patent ID: 7036575

Claim:
A device for modifying the temperature of bedding having 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 upon being turned on 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 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 the 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.
