Method for Introducing Detergents and Associated Washing Machine

Abstract

A method and washing machine that drives a cylindrical drum body, having openings and rotatably supported about an approximately horizontal axis in a tub, in a preferred direction of rotation, and that flows a detergent-liquid mixture in a stream onto an area of an upper quandrant of the cylindrical drum at an oblique angle against the preferred direction of rotation.

1 - 8 . (canceled) 
   
   
       9 . A method for introducing detergents in program-controlled washing machines, the method comprising:
 driving a cylindrical drum body, having openings and rotatably supported about an approximately horizontal axis in a tub, in a preferred direction of rotation; and   flowing a detergent-liquid mixture in a stream onto an area of an upper quandrant of the cylindrical drum at an oblique angle against the preferred direction of rotation.   
   
   
       10 . The method of  claim 9 , wherein the preferred direction of rotation results in the detergent-liquid mixture falling downwards in a flow pointing away from a drain opening in the tub. 
   
   
       11 . The method of  claim 9 , wherein the preferred direction of rotation results in the detergent-liquid mixture entering more quickly through the openings in the drum body or is expelled through the openings more effectively than in an opposite direction of rotation to the preferred direction. 
   
   
       12 . The method of  claim 9 , wherein the flowing comprises distributing the flowing over the width of the drum body into the tub according to the depth of the washing drum. 
   
   
       13 . The method of  claim 9 , wherein driving the cylindrical drum body comprises controlling a speed of rotation of the drum body. 
   
   
       14 . A washing machine comprising:
 a detergent dispenser controllable for temporarily storing an output of detergent;   a detergent feed line extending from an area of a tub and for directing a stream of detergent-liquid mixture falling from a mouth of the detergent feed line onto a surface of a washing drum from above at an oblique angle; and   a drive motor for controlling a direction of rotation of the washing drum and for rotating the washing drum in a preferred direction of rotation against the stream.   
   
   
       15 . The washing machine of  claim 14 , wherein the washing drum comprises openings in a drum surface which in each case have an admittance or an expulsion effect which are greater on rotation of the washing drum in the preferred direction of rotation than they are during rotation in the direction opposite to the preferred direction of rotation. 
   
   
       16 . The washing machine of  claim 14 , wherein the drum surface comprises structures which delay an unhindered draining of the detergent-liquid mixture.
