Arrangement for dispensing liquid detergents and/or rinse aids in a washing machine
First Claim
1. A liquid detergent and/or rinse aid dispensing arrangement for washing machines, in particular clothes washing machines or combined clothes washing and drying machines, comprising a wash tub supported within a cabinet;
- a sealed enclosure (s) containing the liquid detergents and/or rinse aids required for a clothes washing process to be performed in the machine a first conduit (14) in communication with said enclosure;
an additional conduit (28) in communication with the first conduit;
coupling means (25) disposed on the additional conduit (28); and
suction means communicating with said wash tub and said enclosure through the additional conduit (28), so as to draw the liquid detergents and/or rinse aids from said sealed enclosure (8) and deliver them into said wash tub, characterized by connector means (11) connectable to and disconnectable from said sealed enclosure (8), said first conduit (14) and said coupling means (25);
valve means (32) provided on said connector means, said connector means (11) operating said valve means (32) from a first operating position, in which said first conduit (14) and said additional conduit (28) communicate with each other, when said connector means (22) are connected to said coupling means (25), to a second operating position in which said first conduit (14) and said additional conduit (28) are not communicating with each other, when said connector means (11) are disconnected from said coupling means (25); and
actuating means (45) provided on said connector means to enable said connector means (11) to be connected to and disconnected from said coupling means (25).

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.
