Abstract: A valve for use in machines for washing, such as washing machines for laundry, dishwashers and the like, includes a hollow valve body wherein a current of water flows, entering the valve body via at least one inlet of the valve, and at least one plug element for allowing and, respectively, preventing the outflow of water from a corresponding outlet of the valve. The valve is connected to at least one temperature sensor device having a first and a second working state corresponding to an open and closed condition of an electrical connection and in that the sensor device has a preset trigger temperature which, when reached, causes the change from a state of closure to one of opening of the connection or vice versa. Methods of treating the water in these machines for washing also can be implemented with the valve and machines for washing using this valve.

Abstract: An assembly for the selective supply of detergents or the like to the washing drum of a washing machine comprising a drawer (23) for holding detergents having a fixed body (32) and a mobile portion (33) provided with at least a first and a second compartment (34, 35) for containing a respective detergent, said fixed body (32) having at least a first and a second inlet member (34a, 35a) for a flow of liquid for removing the detergent from a respective compartment (34, 35) which is then discharged enriched with detergent into the washing drum of the washing machine, and a valve device (38) comprising a collector pipe (39) for collecting the flow of liquid for removing the detergent and at least a first and a second valve element (44, 45) each having a respective bowl (44a, 45a) leading into said collector pipe (39) and a respective outlet member (44d, 45d) for emission of a respective flow of liquid towards a corresponding inlet member (34a, 35a) of the detergent drawer (23).
