• the hose is advantageously fixable in the sealing area.
• the inner volume of the tube can generally be designed in a simple manner so that the volume corresponding to the known liquor pumping strands is set, for example over the length or the inner diameter of the tube.
• the hose is at least partially a corrugated hose, preferably made of plastic, in particular polypropylene.
• the inner diameter of the hose is dimensioned differently or variably, in particular if it has an enlarged diameter in the connection area to the washing machine.

• the upper discharge line 26 may be connected to a drain or hung in a drainage basin 28.
• the volume of the return tank 30 is about so large that after pumping out of the liquor, when the drain pump 24 is stopped, coming from the Abpumpschlauch 25, 26 and the return tank 30 through the drain pump 24 lye comes to a level which something is above the height of the bottom portion 18 of the tub 2. This ensures that, on subsequent addition of detergent from the detergent dispenser 12, this detergent does not disappear in the drain line 20 at the bottom 18 of the tub 2, but is flushed into the laundry drum 6 by the water of the water line 8 also to be added.
