Abstract
An additive delivery device includes a water supply waterway; and a delivery unit to deliver additives to the water supply waterway; an outlet of the water supply waterway being connected to a nozzle structure. A washing machine includes an inner drum configured to hold a load and the additive delivery device. An inlet of the water supply waterway communicates with a water inlet pipe, and the nozzle structure of the additive delivery device jets an additive solution towards the inside of the inner drum of the washing machine. Additives in the washing machine directly flow to the nozzle structure by the water supply waterway and are directly jetted into the inner drum by the nozzle structure without passing through a water box and an outer drum outside the inner drum, and then, onto the load in the inner drum to increase the utilization ratio of the additives.
