Abstract

A discharge unit for washing machine provided with a washing tank is described. The unit comprises a filter container (1) connected with the tank and in which a filter (2) for the filtering of the washing water coming from the tank is housed. The filter container (1) is fixedly mounted to a discharge pump container (100) provided with an impeller (9) for the conveying of the filtered washing water towards a discharge duct (7). Between the filter (2) and the impeller (9) a wall (4) is arranged that is provided with an opening (5) with which a non-return valve is associated (10, 20) which maintains said opening (5) open by means of action of the same washing water during a normal operation of discharge of the washing water and which maintains said opening (5) closed by the action of the back-flow water from the discharge pipe (7) at the end of the discharge operation.
