Kind Code:
A1
Abstract:
The present invention provides an additive dispensing device, comprising: a water supply passage; and a dispensing unit, configured to dispense an additive to the water supply passage; the water supply passage is internally provided with a turbulence structure for forming a swirl water flow in the water supply passage so as to mix the fed additive with supplied water; and an outlet of the water supply passage is connected to a nozzle. Further disclosed is a washing machine, comprising: a washing drum for containing a load to be processed; and the additive dispensing device, an inlet of the water supply passage of the additive dispensing device being in communication with a water inlet pipe of the washing machine, and the nozzle of the additive dispensing device spraying an additive solution towards the inside of the washing drum of the washing machine. In the present invention, by providing a turbulence structure in the water supply passage, the mixture of the additive and water in the water supply passage forms a swirl water flow when flowing through the turbulence structure, so as to agitate the additive and the water for mixing, thereby achieving significant technical progress of improving the mixing uniformity of an additive solution flowing out of the water supply passage of the additive dispensing device.
