Forced air bed warmer/cooler
First Claim
1. 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.

Abstract
An apparatus and method for modifying the temperature of a bed environment. In preferred embodiments, the invention is a self-contained, forced air bed warmer which pre-heats the interior sheets and covers of a bed to provide a controlled micro-environment that facilitates relaxation into restful sleep on cold nights. Preferred embodiments include an air conditioning section comprising a body portion and a handle portion, said air conditioning section having an exterior surface that is adapted to receive an edge of a bed cover between said body portion and said handle portion; a fan; a heat transfer element; a temperature sensor; a control circuit connected to said temperature sensor; a timer mounted within said air conditioning section; and an elongated air delivery section having two ends with an air entrance at one end and a primary air exit at the other end.
