Improvement in sump flushing on washing machines

In a washing machine with a circulation line 7, washing liquor is scooped through a shaft 7', by means of a guide plate 6 arranged in the tub 1, into a slot 6' formed by the guide plate. The guide plate and the wall part of the tub provide the shaft 7', the shaft being part of the circulation line 7. The washing liquor flows through the circulation line 7 into the sump 8 of the washing machine and there conveys undissolved washing agent back into the tub. The slot 6' of the guide plate 6 is located in the tub somewhat above the upper level II of the washing liquor, so that during the washing operation, with the washing drum rotating, washing liquor passes in the direction of the slot 6' into the circulation line and improves the flow there.
