Abstract
A turbulent flow structure is arranged in a water supply waterway and configured to form a vortex water flow, and mixes a delivered additive with inflow water; and an outlet of the water supply waterway is connected with a nozzle. An inlet of the water supply waterway of the additive delivery apparatus communicates with a washing machine water inflow pipe, and the nozzle of the additive delivery apparatus sprays an additive solution into the washing drum of the washing machine. The turbulent flow structure is arranged in the water supply waterway, so that an additive and water mixed solution in the water supply waterway will form the vortex water flow when flowing through the turbulent flow structure, to stir the additive and the water to be mixed, and mixing uniformity of the additive solution flowing out of the water supply waterway of the additive delivery apparatus is achieved.
