ABSTRACT:
A hot-air portable clothes drier has a carrying handle, two separate first and second casings one telescopically mateable within the other. Both casings include homogeneously dispersed hot-air exhaust ports directing exhaust air in a common direction. Each has outer cover portions with linearly extending elongated strips spaced-apart from one another. Elongated strips of a first casing mateably and telescopically intermeshing with those of a second casing. The elongated strips of each casing having free-space therebelow in the extended state and overlapping to cover and encase their opposite hot-air exhaust ports when in a retracted position of intermeshed portable intermittently locked state. Air intake ports in the first casing are channeled to direct intake air into contact with hot-air heating electrical elements powered by electricity through a retractable electric cord having in electrical series circuit therewith a rheostat and rheostat handle which is manually adjustable and setable at any temperature setting ranging from about room temperature up to about 100.degree. C. at the exhaust ports of the two casings. Other duct structure channels air from the heating elements to the exhaust ports of the first and second casings, with duct structure casings mateably telescoping into each other to the retracted position. In electrical series with the rheostat is an air circulation fan positioned to draw air into the air-intake ports, to propel that air past the heating elements, and to exhaust that heated air through the exhaust ports when switched on by an off-on switch.
