The invention discloses a washing machine. The washing machine comprises a box body, a rotary barrel and a water guide cover, wherein the rotary barrel is rotationally arranged in the box body, wateroutlets are formed in the peripheral wall and/or bottom wall of the rotary barrel; the water guide cover is arranged on the inner peripheral wall surface of the rotary barrel, the water outlets are hermetically covered with the water guide cover, a water inlet is formed in the water guide cover, a water guide cavity communicated with the water inlet and the water outlets is defined by the water guide cover. The liquid rising due to the centrifugal force of the rotary barrel enters the water guide cavity through the water inlet and is discharged from the water outlets. The washing machine in the embodiment adopts a single-barrel structure, the volume is large, water is saved, no contamination is caused, and the cost is low. Under the condition that the dewatering effect is ensured, the material of the box body is not limited, the appearance diversity is improved, and sealing is facilitated.
