Abstract

1,215,482. Washing machines. CANDY S.p.A. 18 Jan., 1968 [18 Jan., 1967], No. 2795/ 68. Heading D1A. [Also in Division A4] Washing machines utilising a demineralisation stop have at least two valves which limit the flow of softened water into the washing tank to that part of the cycle when operations are being carried out above 60‹C. The cycle may be timed so that regeneration of the resin takes place by use of a third valve during the final drying phase of the cycle. The flows of water may be controlled to ensure suitable time for dosing with detergent, demineralisation and regeneration. A cycle is described with prewash at ambient temperature, washing at 75 to 80‹C, two cold rinses, a hot sterilisation rinse at 75 to 80‹C and drying. During drying regeneration of the resin takes place.
