    • A washing machine pumps a washing liquid towards an upper portion of a spin tub while a washing cycle is being executed. The washing machine has a pumping unit disposed at an underside of an outer tub so as to pump the washing liquid from a bottom wall of the outer tub to upper portions of the spin tub and the outer tub. The pumping unit has a receptacle which is fixed to the underside of the outer tub, a disc member which is reciprocated in upward and downward directions within the receptacle, a wire having a first end fixed to a center of an underside of the disc member, a synchronous motor connected to a second end of the wire for pulling the disc member downward, and a compression spring installed in the receptacle for upwardly biasing the disc member. The washing machine pumps the washing liquid toward the upper portion of the spin tub while the washing cycle is being executed, so the turbulent liquid flow is created in the spin tub and thereby preventing the articles from tangling with each other, and improving the washing effect.
    • 洗衣机在洗涤循环正在执行时将洗涤液体朝向旋转桶的上部泵送。 洗衣机具有设置在外桶的下侧的泵送单元,以便将洗涤液体从外桶的底壁泵送到旋转桶和外桶的上部。 抽吸单元具有固定到外桶的下侧的容器,在容器内沿向上和向下方向往复运动的盘构件,具有固定到盘构件的下侧中心的第一端的线, 连接到用于将盘构件向下拉动的线的第二端的同步电动机,以及安装在容器中用于向上偏置盘构件的压缩弹簧。 洗衣机在执行洗涤循环的同时将洗涤液泵送到旋转桶的上部,因此在旋转浴缸中产生湍流液流,从而防止物品相互缠结,并提高洗涤效果 。
