Abstract
An ejector for a laundry treatment appliance includes a housing with a flow channel for allowing water flow to flow therethrough. The housing defines a gap which communicates the flow channel with the outside atmosphere. An axis of an ejection hole of the flow channel located upstream of the gap is coaxial with an axis of an injection hole located downstream of the gap. Backflow water is discharged from the ejector's gap. Since the ejection hole and injection hole are on opposite sides of the housing, and because their diameters are approximately equal water flowing to the injection hole covers as much of the injection hole as possible. The waterway's inlet end downstream of the injection hole is closed to maintain pressure. During supply of water, water flow is prevented from passing through the gap and relieving pressure.
