Assembly for warming towels and the ambient air
A heating unit comprising an outer shell defining a portion of the heating unit periphery, an inner shell disposed within the outer shell and defining an internal cavity, an intermediate cavity formed by the inner and outer shells, a plurality of openings in the inner shell providing air flow between the intermediate cavity and the internal cavity, a heating source, a distribution device transferring heated air from the heating source to the intermediate cavity, a plurality of ambient air vents, and wherein the heated air traverses the plurality of ambient air vents and the plurality of openings.
1. A heating unit comprising:
a shell defining an internal cavity having a pair of external sidewalls and a rear wall:
a heating source;
ducting operationally extending between the heating source and the internal cavity;
a plurality of ambient air valves in communication with the internal cavity and the ambient air;
whereby the ambient air valves are adapted to allow air to pass therethrough from the internal cavity to the ambient air; and
an opening accessible from a front side and the ambient air valves are disposed on a front wall of the shell bordering the opening.
2. The heating unit of claim 1 wherein the ambient air vents are sized to assure that the air in the internal cavity initially receives more air than is released.
3. The heating unit of claim 1 further comprising a rack within the internal cavity adapted to support an article to be warmed.
4. The heating unit of claim 3 further comprising an internal wall dividing the internal cavity and wherein the heating source is positioned on one side of the internal wall and the rack is positioned on an opposing side of the internal wall.
5. The heating unit of claim 1 wherein the internal cavity further comprises a plurality of holes in communication with the ducting.
6. The heating unit of claim 5 wherein the plurality of holes have a combined cross-sectional area equal to or greater than a combined cross-sectional area of the ambient air valves.
7. The heating unit of claim 6 wherein the plurality of holes receive air at the same time as the ambient air valves.
8. The heating unit of claim 7 further comprising:
an internal wall spaced from at least one of the external sidewalls, the rear wall and a bottom wall;
a cavity extending intermediate the internal wall and the at least one external sidewall and rear wall; and,
wherein the internal cavity retains at least a portion of the ducting.
9. The heating unit of claim 7 further comprising:
an internal wall spaced from at least one of the external sidewalls and the rear wall;
a cavity extending intermediate the internal wall and the at least one external sidewall, the rear wall and bottom wall; and,
wherein the internal cavity creates at least a portion of the ducting.
10. The heating unit of claim 6 wherein the plurality of holes are formed in the internal wall.
11. The heating unit of claim 10 wherein the internal wall extends adjacent the external sidewalls and the rear wall.
12. The heating unit of claim 3 wherein the rack is carried by a door.
13. The heating unit of claim 1 further comprising a piece of furniture defining a cavity and wherein the shell is sized to fit within the furniture cavity, wherein the piece of furniture is generally rectangular in shape with a width between 10 inches and 24 inches, a height between 14 and 40 inches and a depth between 12 and 36 inches.
14. The heating unit of claim 1 wherein the shell further comprises a plurality of mounting holes for securing the heating unit to a wall through the plurality of mounting holes with a plurality of fasteners.
