A washing machine, a detergent delivery apparatus and a control method therefor. The detergent delivery apparatus comprises: a housing (10), a piston structure (20) located in the housing (10), circumference of the piston structure (20) sliding along inner circumference of the housing (10) in a sealing manner, a first capacity space being formed between the piston structure (20) and a top of the housing (10), a second capacity space being formed between the piston structure (20) and the bottom of the housing (10), and the first capacity space being used for storing detergent; and a detergent outlet (30) connected to the first capacity space; a water inlet (40) and a water outlet (50) connected to the second capacity space, the pipe diameter of the water inlet (40) being greater than the pipe diameter of the water outlet (50) so as to enable the water inlet (40) to push the piston structure (20) when water flows in; a water inlet valve (60), the water inlet valve (60) being connected to a pipe of the water inlet (40); and a controller, the controller being used for controlling the water inlet valve (60). The washing machine and the detergent delivery apparatus control a detergent delivery volume more accurately and are simple in structure and facilitate the popularization. |
