Abstract
In a washing machine, a discharge hole is formed at the bottom of an inner tub, and a discharge control mechanism capable of blocking the discharge hole is arranged at the bottom of an outer tub; the discharge control mechanism includes a stretchable and contractible valve plug; the valve plug moves upward to close the discharge hole; and the valve plug moves downward to open the discharge hole. During washing, the discharge hole is closed, there is no washing water between the inner tub and the outer tub, resulting in the characteristic of water conservation; and during draining and/or dewatering, the first discharge hole is opened, and the washing water in the inner tub and impurities such as dirt and sand from the clothes are discharged via the discharge hole at the lower part to the outer tub, thus achieving quick draining and good draining and contamination discharging effect.
