Pump-out section for a detergent solution

Abstract

A device for pumping out lye 5 for a washing machine 4 having a washing drum 6, a lye pump 24 and a return flow container 30 arranged in the course of the pumping-out device for filling the drain area in the lye container 2 is to be presented in a cost-effective and easy-to assemble manner. To this end, a lower pumping-out connecting element 25, the return flow tank 30 and an upper pumping-out connecting element 26 is designed in one piece as an at least partially flexible tube 17, which is guided at least partially through a tube holding device 1.

1 - 7 . (canceled) 
   
   
       8 . A washing machine comprising:
 a lye pump;   a washing drum;   a device for pumping out lye having a volume that accommodates a predefined quantity of lye to flow back through the lye pump below the washing drum under gravity when the lye pump is off;   a return flow tank in a course of the device for pumping out lye,   the device for pumping out lye comprising:
 a lower pumping-out connecting element; 
 an upper pumping-out connecting element, wherein the lower pumping-out element, the return flow tank, and the upper pumping-out connecting element comprises a one piece flexible tube; 
 a tube holding device through which the one piece flexible tube is guided; and 
 a sealing area having a preferably cylindrical tube feedthrough inserted therein as well as a connection attached thereto which provides a smooth connection of the one piece flexible tube in the tube feedthrough in a sealed manner. 
   
   
   
       9 . The washing machine of  claim 8 , wherein the one piece flexible tube comprises an integral intermediate part comprising a smooth connection with a ventilation hole. 
   
   
       10 . The washing machine of  claim 9 , wherein the ventilation hole is located precisely in a region of a port of the connection. 
   
   
       11 . The washing machine of  claim 10 , wherein the tube is fixed in the sealing area. 
   
   
       12 . The washing machine of  claim 8 , wherein the tube comprises a polypropylene corrugated tube. 
   
   
       13 . The washing machine of  claim 8 , wherein the tube has a differently dimensioned internal diameter, in particular an enlarged diameter at the connection region on the device side. 
   
   
       14 . The washing machine of  claim 8 , wherein the tube holding device comprises a first straight subarea facing the connection region on the device side, said first straight subarea merging via a curved area into a second subarea in the course of a drain area, said second straight subarea lying perpendicular to the first straight subarea.
