Definitions
- the present invention relates to a liquid flow circuit for employ in a laundry washing machine with the object of ensuring complete utilization of the detergent supplied to the washing water.
- the invention provides that once the operation of the machine has been initiated, the washing water with the detergent added thereto is recirculated, so that the detergent is exhaustively utilized.
- a tub 1 housing a drum 2 containing the laundry to be washed is supplied with water through a conduit 3 having a solenoid valve 4 inserted therein.
- the washing liquid is discharged through a lower conduit 5 connected to the bottom of tub 1, and an electric pump 6 equipped with a filter.
- the outlet of pump 6 is connected to a switch valve 7 the valve element 8 of which is actuated by a solenoid device 9, so that the assembly constitutes a solenoid switch valve.
- a conduit 10 connects one outlet of switch valve 7 to a second switch valve 11 comprising a solenoid 12 for actuating a valve element 13. Another outlet of first switch valve 7 is connected to a conduit 15 formed as a discharge siphon 16 having a discharge outlet 17.
- the outlets 14 and 18 of second switch valve 11 are connected to respective inlets of a detergent supply receptacle 19 provided with a plurality of compartments for containing the detergents to be used for the washing operation.
- elctric pump 6 is energized for directing the water into a compartment of first switch valve 7, from where the water flows through conduit 10 towards supply receptacle 19.
- Second switch valve 11 is operated to direct the water selectively into the pre- washing or main washing compartments of receptacle 19 as required by the respective washing program of the machine, so that the detergent contained in the respective compartment is entrained by the water flowing therethrough.
- Electric pump 6 is then intermittently operated to ensure that the solution of water and detergent is exhaustively utilized.
- first switch valve 7 is operated to direct the liquid towards conduit 15 for discharge therethrough.
- solenoids 9 and 12 The energization of solenoids 9 and 12 is controlled by the program control unit of the machine in accordance with the operating program of the machine.
