The invention discloses a distributed dewatering control method for a roller washing machine. The distributed dewatering control method for the roller washing machine comprises the following steps: setting a pre-throwing stage; setting a first eccentric value in the pre-throwing stage; detecting the relation between an actual eccentric value and the first eccentric value; controlling the washing machine to enter a distributed dewatering stage when the detected actual eccentric value is smaller than or equal to the first eccentric value; and controlling the washing machine to adjust load eccentricity when the detected actual eccentric value is greater than the first eccentric value. The pre-throwing stage is set; when the load eccentricity is adjusted, by setting pulse which controls a roller to rotate in a certain time and at a certain rotating speed, a disperse effect of a load center in the roller is achieved, and part of water is thrown out but cannot be attached to an inner roller; and when the first eccentric value is set as an eccentric value which corresponds to a dewatering maximum rotating speed, the load eccentricity is adjusted to meet an eccentric value which corresponds to the dewatering maximum rotating speed in the distributed dewatering stage, the roller enters the distributed dewatering stage at the eccentric value which corresponds to the dewatering maximum rotating speed, and therefore, dewatering of the roller at the highest speed in low-noise and low-vibration states is implemented.
