Abstract
A drum washing machine with a washing water circulation unit adapted to completely dissolve detergent supplied together with washing water and to enhance washing efficiency. During a washing operation, the washing water contained in a fixed drum is raised or drawn to a center portion of a rear panel of a rotatable drum by turning force of the rotatable drum and then sprayed into the rotatable drum through a nozzle. The circulated washing water accelerates the dissolution of the detergent, and the sprayed washing water directly impinges on laundry, thereby shortening the amount of time required to wet the laundry with the washing water. Therefore, the washing efficiency of the drum washing machine can be remarkably enhanced using only a small quantity of the washing water.
