Drum washing machine

Abstract

A drum washing machine includes a water tub ( 10 ), a rotating tub ( 14 ) mounted in the water tub ( 10 ) to be rotated about a transverse axis, an elastic support ( 11 ) for elastically supporting the water tub ( 14 ), and an auxiliary baffle ( 23 ) formed on the inner peripheral wall of the rotating tub ( 14 ) so as to be close to one of the end plates of the rotating tub and away from the other end plate of the rotating tub ( 14 ). The auxiliary baffle ( 23 ) extends in a direction of axis of the rotating tub ( 14 ). The auxiliary baffle ( 23 ) moves laundry in the rotating tub ( 14 ) near a center of gravity of a member of vibration system applying load to the elastic support ( 11 ).

       5 . The drum washing machine according to  claim 4 , characterized in that the center of gravity of the vibration system member is located nearer to the one end plate side than an axial center of the rotating tub ( 14 ), and the second baffle is larger than the first baffle.  
   
   
       6 . The drum washing machine according to  claim 1 , further comprising a plurality of main baffles ( 20 ,  21 ,  22 ) provided on an axial center of the inner peripheral wall of the rotating tub ( 14 ) so as to extend in a direction of axis of the rotating tub ( 14 ), characterized in that a peripheral position of the auxiliary baffle ( 23 ) with respect to the rotating tub ( 14 ) differs from peripheral positions of the main baffles ( 20 ,  21 ,  22 ) with respect to the rotating tub ( 14 ).  
   
   
       7 . The drum washing machine according to  claim 6 , characterized in that the auxiliary baffle ( 23 ) and the main baffles ( 20 ,  21 ,  22 ) are disposed so as to be spaced peripherally away from each other with respect to the rotating tub ( 14 ).  
   
   
       8 . The drum washing machine according to  claim 1 , characterized in that the auxiliary baffle ( 23 ) extends so as to be tapered from one of the end plates of the rotating tub ( 14 ) toward the other end plate of the rotating tub ( 14 ).  
   
   
       9 . The drum washing machine according to  claim 1 , characterized in that the auxiliary baffle ( 23 ) has a radial dimension set at 30 mm or above with respect to the rotating tub ( 14 ).
