ABSTRACT:
An improved cloth-handling machine in which the energy input necessary for evaporating and conducting away water from clothes being dried is minimized. The machine is a tumbler drying or a combination washing/drying machine and includes a casing having a radiant heater disposed adjacent a reflector in its upper portion adapted to heat a tumbler drum rotatably mounted within the casing. Air is withdrawn from the drum and moisture is condensed from the air which is then recirculated back to the interior of the drum. A condenser arrangement, positioned outside the casing, is comprised of an air turbulator portion connected to a drain opening at the bottom of the casing. A spray or mist of cooling water is supplied by way of a nozzle 22 mounted between the turbulator and the drain opening. The turbulator is followed by a filter and a tranquillizing duct leading through a sump to a pump having a syphon-type outlet. From the tranquillizing duct recirculated air is drawn by an impeller and is moved through an air passage between the radiant heater and reflector, so as to be heated and is thence supplied to the interior of the drum by a nozzle projecting through the usual charging opening of the drum.
