Drum

Abstract

This invention is related to a drum ( 3 ), preferably made of plastic and used in washing/drying machines preferably washing machines into which the laundry to be washed is placed and washing by rotating around its central axis with a motor, comprising a torque transmitter ( 4 ), embedded fully or partly into the rear wall of the drum and by the help of its rear wall and transmits the motor driven power to the whole drum ( 3 ).

1 . A drum ( 3 ) to place laundry and washing liquid and being rotated by a motor around its central axis in a tub ( 2 ) in washing/drying machines, characterized with a torque transmitter ( 4 ) comprising a shaft ( 5 ), which is driven by a motor and a torque distributer ( 7 ) distributing the shaft drive to the whole drum ( 3 ), produced so as not be separated from the material and coated thereof partially or fully to be embedded into the rear wall of the drum and produced as a single piece.  
   
   
       2 . A durum ( 3 ), as defined in  claim 1 , characterized with the torque distributor ( 7 ), which transmits motor drive power via the shaft ( 5 ) to the whole drum ( 3 ), with the help of the rear wall, includes several angular transmitting support elements ( 8 ), which extend from the center where the shaft ( 5 ) is placed towards the sides.  
   
   
       3 . A drum ( 3 ), as defined in  claim 1  or  claim 2 , characterized with the torque distributor ( 7 ) comprises a plate ( 11 ) to transmit motor drive power, via the shaft ( 5 ), to the whole drum ( 3 ) with the help of its rear wall.  
   
   
       4 . A drum ( 3 ), as defined in any of the previous claims, characterized with the torque distributor ( 7 ), which transmits motor drive power, via the shaft ( 5 ), to the whole drum ( 3 ), with the help of its rear wall, includes one or more circular transmitting support elements ( 9 ) which prevent the cracking of the material forming itself, during the production while the material transforms from liquid phase to the solid phase.  
   
   
       5 . A drum ( 3 ), as defined in  claim 1  to  4 , characterized with the torque transmitter ( 4 ), having one or more perforations ( 12 ), on the angular transmitting support element ( 8 ) and/or circular transmitting support element ( 9 ) and/or the connecting plate ( 11 ), to ensure that the torque distributor ( 7 ), does not release and separate from the material forming and surrounding itself ( 7 ).  
   
   
       6 . A drum ( 3 ) as defined in  claim 1  to  5 , characterized with the torque transmitter ( 4 ), includes a mould positioning extension ( 10 ), on the torque distributor ( 7 ), to ensure its right positioning in the mould.  
   
   
       7 . A drum ( 3 ), as defined in  claim 1  to  6 , characterized with the torque transmitter ( 4 ) comprises a bushing ( 6 ) preferably made of brass and having a smooth surface to provide the installation of the shaft ( 5 ) and the torque distributor ( 7 ) onto each other or to provide the formation of a step on the shaft ( 5 ), to ensure placing them onto the tub ( 2 ).  
   
   
       8 . A drum ( 3 ), as defined in  claim 3 , characterized with the plate ( 11 ) comprises several recesses ( 13 ) to transmit the motor drive power with the help of the shaft ( 5 ) to the whole drum ( 3 ).  
   
   
       9 . A drum ( 3 ), as defined in  claim 8 , characterized with a plate ( 11 ) comprising several protrusions ( 14 ) to transmit the motor drive power with the help of the shaft ( 5 ) to the whole drum ( 3 ).  
   
   
       10 . A drum ( 3 ), as defined in  claim 1  to  claim 9 , which is made of plastic material.
