a shaft positioned in the interior of the agitator post, the shaft movable along a vertical direction between an up position and a down position, the shaft having an upward end and a downward end;
a detent positioned at the receptacle, the detent configured for removable receipt of the downward end of the shaft when the bottom end of the agitator post is positioned in the receptacle; and
an actuator positioned near the top end of the agitator post and in mechanical communication with the shaft, the actuator configured for selectively moving the shaft between the up position and the down position.
2. The washing appliance of claim 1 , wherein the actuator is pivotally supported by the agitator post within an opening defined in the agitator post, wherein the actuator is movable in and out of the agitator post, and wherein the actuator is connected with the upward end of the shaft.
3. The washing appliance of claim 2 , wherein the actuator further comprises a pair of opposing support arms received by the agitator post.
4. The washing appliance of claim 3 , wherein the agitator post defines a pair of hooks for receipt of the opposing support arms.
5. The washing appliance of claim 3 , wherein the actuator includes a connecting arm extending into the interior of the agitator post, the connecting arm defining an opening for receipt of the upward end of the shaft.
6. The washing appliance of claim 1 , wherein the receptacle and the bottom end of the agitator post define complementary threads to releasably secure the agitator post by rotation within the receptacle.
7. The washing appliance of claim 6 , wherein the downward end of the shaft is positioned at the detent after the agitator post is rotated into position within the receptacle.
8. The washing appliance of claim 1 , wherein the shaft comprises a rod defining at least one bend at the downward end.
9. The washing appliance of claim 1 , wherein the detent comprises a recess defined by the impeller.
10. The washing appliance of claim 1 , wherein the agitator post further comprises a helical vane extending around an outer surface of the agitator post and the impeller comprises a plurality of lobes spaced-apart along a circumferential direction of the impeller.
11. A washing appliance, comprising:
a wash tub positioned in a wash chamber;
a wash drum rotatably mounted within the wash chamber and configured for receiving articles for washing;
an impeller positioned in the wash drum, the impeller being rotational about a vertical axis and configured for imparting motion to the articles during washing;
a receptacle supported by the impeller;
an agitator post having a top end and a bottom end, the bottom end configured for removable receipt in the receptacle;
a shaft carried by agitator post, the shaft movable between an up position and a down position, the shaft having an upward end and a downward end;
a detent positioned at the receptacle;
the detent positioned below the downward end of the shaft when the agitator post is positioned into the receptacle; and
an actuator supported on the agitator post and connected with the shaft, the actuator configured for movement relative to the agitator post so as to selectively move the shaft between the up position and the down position.
12. The washing appliance of claim 11 , wherein the actuator is pivotally supported by the agitator post, and wherein the actuator is movable in an out of an opening in the agitator post.
13. The washing appliance of claim 12 , wherein the actuator further comprises a pair of opposing support arms received by the agitator post.
14. The washing appliance of claim 13 , wherein the agitator post defines a pair of hooks for receipt of the opposing support arms.
15. The washing appliance of claim 13 , wherein the actuator includes a connecting arm having an opening in receipt of the upward end of the shaft.
16. The washing appliance of claim 11 , wherein the receptacle and the bottom end of the agitator post define complementary threads to releasably secure the agitator post by rotation within the receptacle.
17. The washing appliance of claim 16 , wherein the downward end of the shaft is positioned over the detent after the agitator post is rotated into position within the receptacle.
18. The washing appliance of claim 11 , wherein the shaft comprises a rod defining at least one bend at the downward end.
