  • Publication number: 20170211223
    Abstract: Disclosed herein are a washing machine including an air-stream guide configured to guide a rotating air-stream generated by rotation of the drum toward the spray opening. The washing machine having the circulation apparatus can prevent water or bubbles remaining in the tub and the pump room from flowing into the inside of the drum along the circulation path of the circulation apparatus, due to a pressure difference made between the center area and the outer area of the tub during spin-drying in which the drum rotates at high speed.
