A washing appliance with an agitator post configured for removable positioning in a receptacle. An actuator is used to selectively control the position of a shaft to as to provide for releasably locking the agitator post into position. A detent is positioned at the receptacle and can be configured for removable receipt of the downward end of the shaft when the bottom end of the agitator post is positioned in the receptacle.

A laundry treating apparatus is provided. The laundry treating apparatus includes a cabinet, a drum accommodated in the cabinet, and a dynamic absorber provided to absorb oscillation of the cabinet. The dynamic absorber includes a first moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet and a second moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet. Each of the first and second moving masses includes a single mass made of a metal material or a mass in which a plurality of thin metal plates are coupled to overlap each other, and the first moving mass has a mass greater than that of the second moving mass.

The dynamic absorber includes a support plate coupled to the cabinet, a first moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet, and a second moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet. A support comes into line or point contact with a bottom surface of the first moving mass so that the first moving mass has reduced attenuation ratio in comparison to the second moving mass.

A washing machine appliance may include a tub, a basket, an impeller base, and an extended post. The impeller base may be rotatably mounted within the basket. The impeller base may include an impeller platform and a mounting face defined on the impeller platform. The mounting face may define a recessed cup. The extended post may be removably attached to the impeller base to rotate therewith. The extended post may define an interior cavity. The extended post may include a mating collar and an attachment piston. The mating collar may be on the bottom end in selective engagement with the mounting face at the recessed cup. The attachment piston may include a piston flange extending radially outward at an upper piston end and define an upper radial contact surface in selective engagement with a portion of an inner surface of the mating collar.

A washing appliance with an agitator post configured for removable positioning in a receptacle. A shaft may be supported by the agitator post, the shaft rotatable relative to the agitator post. A plurality of movable tabs may be positioned at the bottom end of the agitator post and in mechanical communication with the shaft such that a direction of rotation of the shaft causes the plurality of movable tabs to be selectively movable along a radial direction between an extended position in contact with the receptacle that prevents rotation of the agitator post relative to the receptacle and a retracted position that allows rotation of the agitator post relative to the receptacle.

A washing machine appliance may include a tub, a basket, an impeller base, and an extended post. The impeller base may include one or impeller fins and a mounting face. The mounting face may include a threaded bracket defining a mounting thread extending about a rotation axis. The mounting face may define a vertical slot radially inward from the mounting thread.. The extended post may be removably attached to the impeller base to rotate therewith. The extended post may include a base body, an auger fin, and a mating face. The base body may extend between a bottom end and a top end. The auger fin may extend radially from the base body. The mating face may be disposed on the bottom end. The mating face may define a mating thread matched to the mounting thread to rotatably enmesh therewith.
