Abstract
An ejector for a laundry treatment appliance, a dispensing device and a laundry treatment appliance is disclosed. The ejector has a front chamber portion, a connection portion and a rear chamber portion connected in sequence. A flow channel is provided in the front chamber portion. The connection portion has a gap which communicates the flow channel with the outside atmosphere. An ejection hole of a water outlet end of the front chamber portion allows water to flow into an injection hole of a water inlet end of the rear chamber portion via the connection portion. The rear chamber portion includes a variable-diameter flow channel with a cross-sectional dimension gradually increasing in a direction of water flow. Backflow water is discharged from the gap of the ejector. The variable-diameter flow channel is arranged downstream of the gap and thereby prevens water flowing back into an upstream tap water pipe.
