Abstract

A washing machine includes a washing machine body provided with a window portion at a front plate; an outer drum arranged in the washing machine body and having at least a transparent area formed by a transparent member at a portion corresponding to the window portion; a dewatering drum rotatably arranged in the outer drum; a motor configured to rotate to drive the dewatering drum; and a drum cleaning unit arranged between the outer drum and the dewatering drum and disposed at a position corresponding to the window portion and the transparent area and capable of abutting against an outer surface of the dewatering drum.

1 . A washing machine, comprising:
 a washing machine body, wherein a side plate of the washing machine body is provided with a window portion;   an outer drum, wherein the outer drum is arranged in the washing machine body, and has at least a transparent area formed by a transparent member at a portion corresponding to the window portion;   a dewatering drum rotatably arranged in the outer drum;   a motor, configured to rotate to drive the dewatering drum; and   a drum cleaning unit, wherein the drum cleaning unit is arranged between the outer drum and the dewatering drum and disposed at a position corresponding to the window portion and the transparent area, and is capable of abutting against an outer surface of the dewatering drum.   
     
     
         2 . The washing machine according to  claim 1 , wherein:
 the drum cleaning unit comprises a supporting shaft portion extending along a direction parallel to a rotating shaft of the dewatering drum; and a brush portion separately arranged in a direction orthogonal to the rotating shaft relative to the supporting shaft portion; and   the washing machine comprises an abutting/separating unit configured to cause the drum cleaning unit to rotate about the supporting shaft portion, so as to make the drum cleaning unit in one of an abutted state and a separated state, wherein the abutted state refers to a state that the brush portion abuts against the outer surface of the dewatering drum, and the separated state refers to a state that the brush portion is separated from the outer surface of the dewatering drum.   
     
     
         3 . The washing machine according to  claim 2 , wherein the abutting/separating unit comprises a torque motor, and a driving force for driving the drum cleaning unit to rotate is applied by the torque motor. 
     
     
         4 . The washing machine according to  claim 2 , wherein
 the drum cleaning unit comprises a connection portion connecting the brush portion and the supporting shaft portion,   a water path having a main stream portion and a plurality of injection portions is formed in the connection portion, wherein the main stream portion is gradually reduced in diameter from a start end to a tail end, and extends along the direction parallel to the rotating shaft of the dewatering drum, and the plurality of injection portions open from the main stream portion to the brush portion and are formed at a plurality of positions along the direction parallel to the rotating shaft of the dewatering drum respectively, and   the washing machine comprises a water supply unit for supplying water to the main stream portion from the start end.   
     
     
         5 . The washing machine according to  claim 1 , wherein the drum cleaning unit is configured to be detachable between the outer drum and the dewatering drum. 
     
     
         6 . The washing machine according to  claim 1 , wherein at least a portion of the dewatering drum is formed by a transparent member. 
     
     
         7 . The washing machine according to  claim 3 , wherein:
 the drum cleaning unit comprises a connection portion connecting the brush portion and the supporting shaft portion,   a water path having a main stream portion and a plurality of injection portions is formed in the connection portion, wherein the main stream portion is gradually reduced in diameter from a start end to a tail end, and extends along the direction parallel to the rotating shaft of the dewatering drum, and the plurality of injection portions open from the main stream portion to the brush portion and are formed at a plurality of positions along the direction parallel to the rotating shaft of the dewatering drum respectively, and   the washing machine comprises a water supply unit for supplying water to the main stream portion from the start end.   
     
     
         8 . The washing machine according to  claim 2 , wherein the drum cleaning unit is configured to be detachable between the outer drum and the dewatering drum. 
     
     
         9 . The washing machine according to  claim 3 , wherein the drum cleaning unit is configured to be detachable between the outer drum and the dewatering drum. 
     
     
         10 . The washing machine according to  claim 2 , wherein at least a portion of the dewatering drum is formed by a transparent member. 
     
     
         11 . The washing machine according to  claim 3 , wherein at least a portion of the dewatering drum is formed by a transparent member.
