In such scheme, generally rotary drum washing machine drives clothes washing, but clothing mainly by the stirring of impeller
Thing is not easy to be broken up at center, and is very easily intertwined, typically can be in impeller in order to solve the problems, such as winding
The centrally disposed runner rotated freely, the present invention is in the centrally disposed center runner 3 of free rotation of impeller so that clothing holds
Easily broken up and will not be wound, strengthen clean result.But because center runner 3 is rotated along the central shaft on impeller,
Or the central shaft rotation that edge connects with impeller, the bottom of center runner 3 contact with the surface of impeller under gravity, are turning
By frictional force when dynamic, the coefficient of friction between plastics is bigger, and the time has grown the hidden danger for having damage；In addition, traditional center
Space between runner bottom and impeller surface be present, center runner easily produces deviation when rotating, causes center runner and impeller
Surface local friction is frequent, produces abrasion or other directions produce bigger space, easy card clothing or batting etc. so that
Center runner frictional force is bigger, more fragile.And the dismounting and replacing of impeller need professional person to operate, client is difficult certainly
Row dismounting and change, this just adds worry for client.The present invention sets smooth supporting construction, reduce center runner and impeller it
Between friction, the simple rule of current, clothing at center is not wound, strengthen clean result, also reduce center runner 3 and rub
Damaged caused by impeller surface.The smooth supporting construction may be provided on impeller, may also be arranged on center runner 3, preferably
