A low temperature clothes dryer having a drying chamber provides removable horizontal screens supporting clothing items and a hanging bar for hanging clothes to be dried. A timing control allows setting the time of operation of the drying cabinet. An electric heater with thermostat is provided to initially raise and maintain the air temperature within the drying chamber to at least about 90 degrees F. The dehumidifier is then operated, providing for circulation through the ducts and drying cabinet by an internal fan. The dehumidifier has an evaporator through which warm, humid air is passed, thereby cooling the air and condensing water therefrom, the water being collected in a removable container or drained through a drain hose. The fan forces the cooled, dried air through a condenser which heats the dried air for recirculation through the drying chamber by means of ducts, thereby drying the clothing therein.

I claim: 1. A low temperature clothes dryer, comprising: a generally rectangular drying chamber having opposed sidewalls, a rear wall, at least one front access door; a plurality of pairs of drying frame supports spaced along said opposed walls of said drying chamber and a plurality of removable drying frame screens having drying frames horizontally supported by said pairs of drying frame supports; an upper plenum, and a lower plenum, defining and being in communication with said drying chamber, wherein said lower plenum comprises a horizontal air flow distributing wall defining a plurality of air flow apertures communicating with the interior of said drying chamber, and wherein said upper plenum comprises a horizontal air flow receiving wall defining a plurality of air flow apertures communicating the said interior of said drying chamber; a clothes hanging bar supported by a pair of hanging bar supports located on said opposed walls of said said drying chamber proximate said air flow receiving wall of said upper plenum; a wet air return duct having an inlet connected with said rectangular drying chamber via said lower plenum and an outlet; a dehumidifier connected with said outlet of said wet air return duct, said dehumidifier having an expansion coil condenser in fluid communication with said wet air return duct, a circulating fan, and a heat radiator; a baffle within said dehumidifier and a compressor, said compressor being separated from the air circulating interior of said dehumidifier, said compressor being vented to the exterior of said clothes dryer so as to carry heat developed thereby to the surrounding atmosphere; and an air recycle duct having an inlet in fluid communication with said heat radiator of said dehumidifier and an outlet in fluid communication with said upper plenum, said air recycle duct having an upper portion and a lower portion, said upper portion being connected with said upper plenum, said lower portion forming a wet air return duct being in fluid communication with said expansion coil condenser of said dehumidifier; said drying chamber, said wet air return duct, said dehumidifier, and said recycle duct forming a closed, circulating air drying system, said circulating air drying system being in the form of a cabinet, said cabinet forming a dehumidifying module enclosure beneath said drying chamber, said dehumidifying module being open at the rear for dissipation of heat from said compressor, said dehumidifying module having at least one front door for access to said dehumidifier. 2. The low temperature clothes dryer of claim 1, said lower plenum being further defined by a cabinet base wall, said opposed walls of said drying chamber including an outer wall extending from said base wall upward to form one sidewall of said dehumidifying module enclosure, and including an inner wall extending from said base wall upward to form the other sidewall of said dehumidifying module enclosure. 3. The low temperature clothes dryer of claim 1, further comprising an intermittent thermostatic electric heater located in said lower plenum. 4. The low temperature clothes dryer of claim 1, wherein said wet air return duct inlet is connected with said heat radiator of said dehumidifier. 5. A low temperature clothes dryer, comprising: a generally rectangular drying chamber having opposed sidewalls, a rear wall, at least one front access door; an upper plenum, and a lower plenum, defining and being in communication with said drying chamber; a wet air return duct having an inlet connected with said rectangular drying chamber via said lower plenum and an outlet; a dehumidifier connected with said outlet of said wet air return duct, said dehumidifier having an expansion coil condenser in fluid communication with said wet air return duct, a circulating fan, and a heat radiator; an electrical power source for operation of said dehumidifier and a timer control electrically connected between said power source and said dehumidifier; a humidity sensor and a temperature sensor located in said wet air return duct, each electrically connected with said dehumidifier via a switch wherein upon circulating wet air reaches a certain minimum humidity said dehumidifier is shut off by said switch, and wherein upon circulating wet air rises above a determined temperature, said dehumidifier is shut off by said switch, said switch starting operation upon the wet air temperature cooling below a set temperature; and an air recycle duct having an inlet in fluid communication with said heat radiator of said dehumidifier and an outlet in fluid communication with said upper plenum, said air recycle duct having an upper portion and a lower portion, said upper portion being connected with said upper plenum, said lower portion forming a wet air return duct being in fluid communication with said expansion coil condenser of said dehumidifier; said drying chamber, said wet air return duct, said dehumidifier, and said recycle duct forming a closed, circulating air drying system.
