Disclosed are a clothes classification and storage device, a washing machine and a control method therefor. The clothes classification and storage device includes a controller, a driving mechanism and at least two clothes accommodating parts, where the driving mechanism is configured to drive the clothes accommodating parts to move under control of the controller and deliver any one clothes accommodating part to a set position for clothes throwing. Meanwhile, a washing machine with the above clothes classification and storage device and a control method therefor are proposed. The clothes classification and storage device has at least two clothes accommodating parts, so that clothes to be separately washed can be classified and placed in different clothes accommodating parts by a user, and each clothes accommodating part can be delivered to the set position through the driving mechanism for clothes throwing, thereby realizing automatic classification and throwing of clothes.
