Heating and cooling sleeping system

摘要

A sleeping system is described in which comfort systems for a foam mattress assembly are mounted in a foundation assembly supporting the mattress assembly. The comfort systems include an air heating and cooling system, a firmness system and an elevation system. The foam mattress assembly includes a flexible encasement dish into which one or more foam layers are disposed. Blowers for the air system are mounted adjacent the foundation assembly top in direct fluid communication with apertures in the top, minimizing the air flow path from the blower exhaust to the mattress top to reduce air pressure loss and diminishment of the heated or cooled air.

1. A sleeping system comprising a mattress assembly and a foundation assembly,
the mattress assembly has a top and a bottom and comprises:
a flexible encasement dish having a base and opposing sidewalls extending from the base and at least one opening defined within the base;a first mattress layer disposed within the flexible encasement dish between the sidewalls, wherein the first mattress layer comprises a foam insert having a perimeter, a bottom surface and a top surface with an opening defined in the top surface;at least one elongate air flow passage extending from the bottom surface to the top surface along an axis through the foam insert between the opening in the top surface and the at least one opening defined within the base of the flexible encasement dish; and an air distribution mechanism disposed over the first mattress layer and in fluid communication with the air flow passage, the air distribution mechanism having a perimeter that is less than the perimeter of the foam insert; and the foundation assembly comprises: a top, a bottom and sides extending between the top and the bottom, with an open space formed between the top, bottom and sides, wherein the top and sides are enclosed; the top having at least one aperture defined therein; an air blower positioned in the open space adjacent the top, the air blower having an exhaust in direct fluid communication with the aperture and an air intake open to the open space.
