More Information
Summary:A drum-type washing machine (1), the laundry drum (4) of which is mounted for rotation in a container (5) for detergent solution, has a detergent dispenser (2) for the addition of powdery and/or liquid treatment agents which are flushed out into the container (5) for detergent solution by means of the fresh water flowing in. The container (5) for detergent solution is coupled to a discharge system (6, 8, 9) which consists of a bellows-like drain outlet (6) with a vent pipe (7), a pump (8) for detergent solution and a discharge hose (9), and disposed in the drain outlet (6) is a valve device (11) which closes this during the introduction of the treatment agents. The valve device (11) is formed from resilient clack valve (16) which, when the pump (8) is inoperative, is held in the closed position by the hydrostatic water pressure (h2) in the discharge hose (9) and possibly in the vent pipe (7).
