Active airflow temperature controlled bedding systems
View Patent ↗A climate controlled bedding system includes at least one coil spring layer; and an air supply fluidly coupled to the one or more fluid conduits. In some embodiments, a filter is disposed within a flow path of a fluid conduit.
1. A climate controlled bedding assembly comprising:
a base comprising one or more continuous and linear channels extending from a head end to a foot end, and a porous top surface covering the base;
one or more air supply devices that are external to the base, each air supply device having an inlet and an outlet in fluid communication with an open end of each of the one or more continuous channels, wherein each of the one or more continuous channels include outlets in fluid communication with the porous top surface such that air flows from each inlet of the one or more air supply devices, through each outlet of the one or more air supply devices, into each of the one or more continuous channels, and through the outlets of each one or more continuous channels;
a perforated foam layer overlaying and extending an entire length and width of the base for receiving the air flow, wherein the perforated foam layer includes a plurality of vertically oriented channels formed in the perforated foam layer extending from a bottom surface to a top surface;
a coil spring layer overlaying the perforated foam layer;
an uppermost foam layer overlaying the coil spring layer, the uppermost foam layer including a support surface adapted to substantially face a user resting on the bedding system, and
wherein the air flow follows a path that goes from outside the base to inside the base, the path changing directions from being substantially parallel to a plane of the bottom surface of the perforated foam layer to being substantially perpendicular to the plane outside the base, then to being substantially parallel to the plane inside the base.
2. The climate controlled bedding system of claim 1 , wherein the coil spring layer comprises pocketed coil springs.
3. The climate controlled bedding system of claim 1 , wherein the one or more air supply devices are selected from the group consisting of a fluid transfer device, a thermoelectric device, a convective heater, a heat pump, a dehumidifier and combinations thereof.
4. The climate controlled bedding system of claim 1 , wherein the base defines a foundation for supporting a mattress, and wherein the mattress comprises the perforated foam layer, the coil spring layer; and the uppermost foam layer including the support surface.
5. The climate controlled bedding system of claim 1 , further comprising a filter intermediate each inlet of the one or more air supply devices and the open end of each of the one or more continuous channels.
