Definitions

  • the present invention relates to a laundry washing machine.
  • the present invention relates to a laundry washing machine of the type comprising a device for automatically dispensing and metering at least one laundering product.
  • washing machines of the above type are practically only used professionally, on account of the highly complex design of the automatic product dispensing and metering device, which makes the machine both expensive and difficult to use.
  • EP 0 196 398 discloses a device for delivering metered quantities of liquid products to ateil, comprising a plunger-type pump and a pump control means including a programmable memory of any type, such as a memory card, by means of which the number of strokes of the plunger of the pump, and consequently the quantity of liquid delivered thereby, can be determined.
  • the pump is connected at its suction side to a plurality of liquid containers by a network of pipes each having a controllable valve, the opening and closing of which can be controlled by the pump control means in dependence on the programme stored in the programmable memory.
  • a typicaltown for such device is an industrial washing machine which can thus receive metered quantities of liquid detergents and other additives in place of powders used conventionally without recourse to liquid metering devices of other type and greater complexity.
  • DE 4 000 378 discloses a dosing apparatus adapted to feed an additive into a clothes or dishes washing machine using an electrically operated valve system, the dosing apparatus having precautions for the dosing chamber to be flushed automatically with a rinsing fluid.
  • DE 3 822 246 discloses a metering device for liquids comprising a first valve placed between a reservoir for the liquid and the pump connected to the feedline, and a second valve placed between the water-inflow line and the pump.
  • An optically transparent region of the feedline is provided between the pump and the tub, to which a light source and an optoelectronic switching member are assigned.
  • the metering device is intended particularly for use in washing machines, dishwashers or similar appliances.
  • WO 2006 043118 discloses an ejector system for adding liquid detergent to washing machines which may be annexed to the existing system of the washing machine in such a way that the user can choose at any time between washing with powder detergents or with liquid detergents.
  • the Ejector System consists of an ejector, an electromagnetic valve, a non-return valve and a container (4).
  • a laundry washing machine as claimed in Claim 1 and, preferably, in any one of the Claims depending directly or indirectly on Claim 1.
  • number 1 indicates as a whole a laundry washing machine comprising a wash tub 2 housing a perforated revolving laundry drum (not shown); and an automatic dispensing and metering device 3 for feeding measured quantities of laundering products, e.g. detergent, softener, freshener, etc., into tub 2.
  • laundering products e.g. detergent, softener, freshener, etc.
  • device 3 comprises a water circuit 4 closed by tub 2; two inlets 5 for respective products; and metering means 6, which are interposed between inlets 5 and circuit 4, and, as explained in detail below, inject measured quantities of products into circuit 4, when water flows along circuit 4, to feed a water-product mixture into tub 2.
  • circuit 4 comprises a delivery branch 7 extending from tub 2 to metering means 6 to supply metering means 6 with wash water from tub 2; and a return branch 8 extending from metering means 6 to tub 2 to feed a water-product mixture into tub 2.
  • Circuit 4 also comprises a pump 9 located along delivery branch 7 to pump water from tub 2 along circuit 4 via a solenoid valve 10, which is located along delivery branch 7, downstream from pump 9, and is activated by an external signal as a function of the programmed wash cycle.
  • Each inlet 5 is defined by a fast-fit connector to a respective container 11, which may be replaceable, as in the Figure 1 and 2 embodiment, or refillable, as in the Figure 3 and 4 embodiment.
  • containers 11 are housed in a pull-out drawer 12 formed in a base 13 of machine 1.
  • drawer 12 houses two side by side containers 11 (only one shown in Figure 2 ) defined, in the example shown, by respective disposable cans of enough product for numerous wash cycles.
  • Each inlet 5 (only one shown in Figure 2 ) is defined by the mouth of a respective tank 14 connectable to relative container 11 by a tap 15, the inlet of which is connected in fluidtight manner to an opening in container 11, before container 11 is placed inside drawer 12, and the outlet of which is connected in fluidtight manner to the mouth of tank 14 to connect container 11 to tank 14.
  • Tap 15 comprises a spring-operated valve normally set to a closed position (not shown), and which is set to an open position (shown in Figure 2 ) by means of an external lever 16 hand-operated by the user once tap 15 is connected to tank 14, so container 11 can be connected and disconnected easily, with no leakage, and the product can be gravity-fed into tank 14 only after tap 15 is inserted through inlet 5.
  • metering means 6 are housed, together with container 11 and tank 14, inside drawer 12, and comprise, for each inlet 5, a pump 17 ( Figure 2 shows pumps 17 of both containers 11); an intake conduit 18 connecting the inlet of pump 17 to relative tank 14; and a feed conduit 19 connecting the outlet of pump 17 to a mixer 21 via a one-way valve 20.
  • Mixer 21 to which both feed conduits 19 of relative pumps 17 are connected, defines a portion of circuit 4 connecting the outlet of delivery branch 7 to the inlet of return branch 8, and communicates on one side with delivery branch 7 via a one-way valve 22 to receive water from tub 2, in use, and on the other side with return branch 8 via a one-way valve 23 to feed a water-product mixture into tub 2.
  • Pumps 17 are controlled, as described below, by 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.
  • 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 17a for the sake of clarity).
  • pump 17a 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 17a 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 17a, thus cutting off detergent supply to mixer 21.
  • 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.
  • 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 Figure 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.
  • each container 11 has a tubular opening 29, which, when the container 11 is housed in support 27 ( Figure 4 ), is inserted partly inside the initial portion of a channel 30 formed in support 27 and defining said inlet 5 for the product inside container 11.
  • Each opening 29 has a ball valve, which, when the container is housed in support 27 ( Figure 4 ), is held in an open position by a pin integral with support 27, and, when the container is detached from support 27 (not shown), e.g. for cleaning, closes opening 29 to prevent product leakage from the container.
  • 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.
  • 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.
  • each metering means 6 - be it a pump 9 or a hydropneumatic metering device 31 - 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.
