Disclosed in the present invention are a washing tub assembly of a washing device and a washing device. The washing tub assembly comprises a washing tub and a water agitating member rotatably arranged inside the washing tub. The water agitating member extends upward from the tub bottom of the washing tub, and the radius of the water agitating member is the largest at a particular distance from the tub bottom. The particular distance enables at least some clothes to be washed below a position where the radius of the water agitating member is the largest. In the present invention, relative rotation generated between the water agitating member and the washing tub is employed to stir the clothes and water flow to wash the clothes in the tub. Because the clothes can be washed below the position where the radius of the water agitating member is the largest, the clothes come into contact with the surface of the water agitating member facing the tub bottom, thereby avoiding the problem of dirt being prone to accumulating between a stirring component of a conventional washing device and the tub bottom and being hard to remove. In addition, a relative force between the clothes and the water agitating member can be reduced, thereby reducing energy consumption of a motor used for driving the water agitating member.

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.
