<p>Dispenser in washing machines, adapted to automatically dispense detergent and rinse aid through own actuation means. The actuation means comprise permanent magnet means (23), first lamellar means (24) of iron-nickel alloy, PTC means (25), and second lamellar means (26). The first and second lamellar means (24,26) include the PTC (25) interposed therebetween to form an assembly which is temporarily energized by an electrical power supply (27) until in the first lamellar means (24) a temperature corresponding to the Curie point of the alloy is reached. The permanent magnet means (23) is arranged so as to co-operate with the first lamellar means (24) until said Curie point is reached in the first lamellar means (24). <IMAGE></p> |
