  • a central control unit 25 housed in a main body of machine 1 over base 13 , and connected to pumps 17 by a multipole cable 24 , which, together with delivery branch 7 and return branch 8 , extends from the main body of machine 1 to base 13 through an outside sleeve, and through an extensible member located inside base 13 and outside drawer 12 to permit extension of cable 24 and branches 7 and 8 when drawer 12 is pulled out of base 13 .
  • device 3 For each tank 14 , device 3 comprises two optical level sensors 26 connected to central control unit 25 by multipole cable 24 .
  • central control unit 25 activates the pump 17 connected to the detergent container 11 (hereinafter indicated 17 a for the sake of clarity).
  • pump 17 a detergent is drawn from tank 14 along relative intake conduit 18 and injected along relative feed conduit 19 into mixer 21 at a high enough pressure to open valve 20 .
  • the detergent mixes with the circulating water to form a water-detergent mixture, and is fed along return branch 8 into the laundry inside tub 2 .
  • the detergent is metered automatically, by central control unit 25 controlling the operating time of pump 17 a determined by central control unit 25 on the basis of the programmed cycle parameters, e.g. type and quantity of laundry, type of wash cycle, etc.
  • central control unit 25 stops pump 17 a , thus cutting off detergent supply to mixer 21 .
  • pump 9 continues pumping water along circuit 4 to remove all traces of detergent from mixer 21 and to flush circuit 4 .
  • pump 9 is also stopped, valve 10 is closed, and water no longer flows along circuit 4 .
  • sensors 26 transmit respective signals to central control unit 25 , which disables respective pump 17 until container 11 is changed, and preferably also lights up a “no-product” alarm signal on a display of machine 1 .
  • the above example is limited to feeding a measured quantity of only one product, i.e. detergent, into tub 2 .
  • central control unit 25 is designed to operate pumps 17 of product tanks 14 simultaneously or successively, and to keep each pump 17 operating for the time taken to dispense the required amount of the relative product.
  • the two containers 11 housed inside drawer 12 are two refillable tanks (only one shown in FIG. 4 ), each of which contains enough product for numerous wash cycles, is housed inside a support 27 integral with base 13 , and has a tilting lid 28 to enable the user to top up the product.

  • metering means 6 comprise a hydropneumatic metering device 31 , in turn comprising a cylinder 32 , and a piston 33 slid by compressed air inside cylinder 32 . More specifically, cylinder 32 is closed at one end, and, at the opposite end, is fitted through in fluidtight sliding manner with the rod of piston 33 , an end portion of which, integral with the rod, mates in fluidtight manner with the lateral wall of cylinder 32 , and divides cylinder 32 internally into a first chamber communicating with the delivery side of a compressor 34 , and a closed second chamber housing a spring 35 compressed between the closed end of cylinder 32 and the end portion of piston 33 .
  • piston 33 has an end portion, which mates in fluidtight sliding manner with the lateral wall of a tubular member to define, inside the tubular member, a variable-volume chamber 36 , which, as explained in detail below, stores the measured amount of product drawn from container 11 by hydropneumatic metering device 31 , pending injection into circuit 4 .
  • chamber 36 communicates, on one side, with channel 30 via a one-way valve 37 only allowing product flow into chamber 36 , and, on the other side, with mixer 21 via a feed channel 38 and a one-way valve 39 only allowing outflow of the product from chamber 36 .
  • compressor 34 is housed in the main body of machine 1 , and is connected to each hydropneumatic metering device 31 by a respective tube 40 to selectively feed compressed air to relative cylinders 32 via a three-position solenoid valve 41 .
  • This variation of machine 1 operates in the same way as machine 1 described with reference to FIGS. 1 and 2 , with the exception of the metering mode adopted.
  • an external command activates compressor 34 , which feeds compressed air to cylinder 32 of container 11 of the product to be dispensed, e.g. detergent, so as to overcome the resistance of spring 35 , slide piston 33 inwards of cylinder 32 , and so increase the volume of chamber 36 and form a sufficiently low pressure inside chamber 36 to open valve 37 and feed the product into chamber 36 .
  • compressor 34 which feeds compressed air to cylinder 32 of container 11 of the product to be dispensed, e.g. detergent, so as to overcome the resistance of spring 35 , slide piston 33 inwards of cylinder 32 , and so increase the volume of chamber 36 and form a sufficiently low pressure inside chamber 36 to open valve 37 and feed the product into chamber 36 .
  • automatic metering is a function of the position of piston 33 inside cylinder 32 .
  • each metering means 6 is associated with a respective container 11 , and operates regardless of the presence or number of other metering means 6 .
  • operation of machine 1 as described above also applies, regardless of whether device 3 comprises only one inlet 5 for one container 11 , or more than two inlets 5 for respective containers 11 .
