ABSTRACT:
Disclosed is a washing machine having a centrifugal pump which not only sprays washing liquid onto the articles to be washed by circulating the washing liquid, but also supplies air bubbles into a spin tub, thereby improving the washing effect. The centrifugal pump includes a first housing, a second housing fixedly coupled to the first housing, an impeller accommodated in the first housing so as to circulate the washing liquid into a spraying nozzle or into an outer tub, a rotor which rotates in the forward and reverse directions, a driving shaft inserted into a center of the rotor in order to rotate together with the rotor, and a solenoid valve assembly for supplying the air to the impeller. The washing machine generates complex turbulence in the spin tub, thereby preventing the articles to be washed from being tangled at the center of the spin tub. The air bubbles supplied into the spin tub collide against the liquid flow generated by a pulsator so that they burst and impact against the articles, thereby not only improving the washing efficiency, but also easily dissolving the detergents.
