Abstract
A dispenser for washing machines, in particular clothes washing machines or combined clothes washing and drying machines. The dispenser includes first and second rigid conduits (12, 13) extending orthogonally with respect to each other. The first is connected with a sealed enclosure (8) containing the liquid detergents and/or rinse aids. The second is connected with a quick-fitting coupler (25) that is adapted to be connected and disconnected with respect to a further rigid conduit (28) communicating with the wash tub of the washing machine through a positive-displacement pump. The second rigid conduit (13) is associated with a check valve (32) that is biased by a spring (42) to move from a first to a second position, whereby a communication is therefore established or discontinued between the enclosure (8) and its outer space when the second rigid conduit (13) is engaged and disengaged, respectively, with respect to said quick-fitting coupling means (25). The dispensing arrangement can quickly and easily be installed in and removed from washing machines of the aforementioned type.
