A detergent-free washer and a washing method by a detergent-free washer

摘要

PURPOSE: A non-detergent washing machine and a washing method using the same are provided to execute washing and sterilization steps in one washing tub, to improve washing efficiency by injecting or circulating forcibly the water through a nozzle, and to save the water by using electro-analysis water for a rinsing step. CONSTITUTION: A non-detergent washing machine is composed of a washing tub(11) into which articles to be cleaned are put; an electrolyzing unit(18) for electrolyzing the water contained in the washing tub; a circulation unit for circulating the water; and a purifying unit for purifying the water. The purifying unit is positioned at a purifying unit connection pipe(38) for linking different spots of the pipe through which the water is circulated. The purifying unit purifies the water only in a rinsing step by the operation of a passage switch valve(30) installed at the spot where the purifying unit connection pipe is branched off.
