ABSTRACT:
A device for heating an article such as a towel or the like comprises an enclosure and a heating device for providing heated air under positive pressure to the interior of the enclosure. A support in the form of a rack is arranged in the interior of the enclosure, dividing the enclosure into an upper volume and a lower volume. The towel is adapted for placement onto the upper surface of the rack, and cooperates with the lower wall of the enclosure to define a lower passage within which the heated air under positive pressure is received. Vent openings are provided in the upper portion of the enclosure for providing a bottom-to-top flow path for air supplied to the enclosure, with the towel being disposed in the flow path, and thereby heated by air circulating therethrough.
