Abstract
An automatic feeding device includes a water supply pipeline with at least two outlets and capable of controllably delivering a water flow to one of the water outlets; liquid storage parts containing additives used when clothes are treated; and a pumping structure for pumping out the additives in the liquid storage parts to the water supply pipeline. A multi-drum washing machine includes at least two water tubs; and is provided with the automatic feeding device, wherein each of the water outlets of the automatic feeding device communicates with the water tubs in a one-to-one correspondence way. The additives in the liquid storage parts are pumped out by virtue of a negative pressure generated when the water flow passes through the pumping structure, and are flushed into the corresponding water tubs with an inlet water flow of the washing machine.
