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.
A nozzle structure, comprising a jet pipe, wherein an outlet end of the jet pipe is provided with a spray head, the spray head is provided with a jet outlet, and a flow channel by which water in the jet pipe is guided to the jet outlet and a tangential acceleration of a water flow at the jet outlet is increased is disposed in the spray head.
