A washing appliance having a cabinet and a wash tub positioned in the cabinet and defining a wash chamber. A wash drum is rotatably mounted within the wash chamber and is configured for receiving articles for washing. An impeller is positioned in the wash drum. An agitator post is removably received into a an impeller recess using depressible features for releasable attachment. A removable cap can be placed on the top end of the agitator or into the impeller recess.

A collapsible agitator assembly includes an impeller that is attachable to a drive shaft of a washing machine to rotate clothing in the washing machine for washing. A first agitator tube is attachable to the drive shaft of the washing machine to agitate water in the washing machine for washing. The first agitator tube is retractable into the impeller. A bushing extends upwardly through the first agitator tube. A second agitator tube is attachable to the bushing and the second agitator tube is retractable inside of the first agitator tube to accommodate a small load of laundry. The second agitator tube is extendable upwardly from the first agitator tube to accommodate a large load of laundry.

A driving device for a washing machine includes: a shaft including an inner shaft and an outer shaft surrounding the inner shaft; a motor assembly including a stator, a rotor that surrounds the stator, a modulator that surrounds the rotor, and a magnetic gear rotating body that surrounds the modulator; a first fixation body that connects between the inner shaft and the magnetic gear rotating body; a second fixation body having one end connected to the stator and the other end connected to a tub; and an electronic clutch that disconnects the outer shat and the rotor or connects the inner shaft and the rotor according to an operation mode of the washing machine. The modulator adjusts a speed and torque of the magnetic gear rotating body. The driving device may make a motor drive area highly efficient and may reduce electric consumption.
