1. A device for dispensing washing agents for a household washing machine, in particular a dishwasher, said dispenser (1) having at least a tank (S) for containing a liquid washing agent and an arrangement (11-22;
-
11-21′
) for dispensing a dose of said liquid washing agent, said arrangement comprising;
a passage (12,12A,12B,12C,12′
) for putting the inside of said tank (S) in communication with a discharge outlet (16) for said liquid washing agent, plugging means (13,13′
) for said passage (12,12A,12B,12C,12′
), at least an actuator (11,11′
) for operating said plugging means (13,13′
), characterized in that said plugging means comprise an element (13;
13′
) being axially movable within said passage (12,12A,12B,12C,12′
), said movable element bearing sealing means (18-21,19′
) which operate on at least a surface of said passage (12,12A,12B,12C;
12′
) and are capable of displacement between a first position and a second position, whereby;
in said first position, said movable element (13;
13′
) allows the flowing down of an amount of liquid washing agent from said tank (S) to a dosing space (14;
12′
), in said first position said movable element (13;
131) does not allowing the flowing down of said amount of liquid washing agent from said dosing space (14;
12′
) to said discharge outlet (16);
in said second position, said movable element (13;
13′
) allows the dispensing of said amount of liquid washing agent from said dosing space (14;
12′
) to said discharge outlet (16), preventing at the same time the further flow of liquid washing agent from said tank (S) to said dosing space (14;
12′
).

Abstract
A device for dispensing washing agents is described, for a household washing machine, in particular a diswasher, said dispenser (1) having at least a tank (S) for a liquid washing agent and an arrangement (11-22) for dispensing a dose of said washing agent. The arrangement comprises: a passage (12A, 12B, 12C) for putting the inside of said tank (S) in communication with a discharge outlet (16); plugging means (13) for said passage (12A, 12B, 12C), at least an actuator (11) for operating said plugging means (13). According to the invention, said plugging means comprise an element (13) being movable within said passage (12A, 12B, 12C) and bearing sealing means (18-21), whereby the movable element (13), in a first position, allows to realize the dosage of an amount of washing agent and, in a second position, allows to dispense the dosed amount of washing agent.
