  • detergent dispenser 7 also comprises a siphon 17 located inside first compartment 10, and for discharging the liquid softener from first compartment 10 into feed conduit 13 underneath.
  • siphon 17 comprises two straight sleeves, which fit one inside the other when lid 9 is fixed to container 8. More specifically, a first sleeve 17a is located inside first compartment 10, has a preferably, though not necessarily, circular cross section, and extends upwards from the bottom wall of first compartment 10, in a direction parallel to the mid-plane of container 8, so that its bottom end communicates with feed conduit 13, and its top end communicates with first compartment 10.
  • a second sleeve 17b of siphon 17 has a preferably, though not necessarily, circular cross section larger in outside diameter than first sleeve 17a, and is connected to lid 9 inside first opening 18.
  • second sleeve 17b extends downwards from the plane of frame 15, with its axis parallel to the mid-plane of lid 9, and is connected to frame 15 by a lateral supporting appendix 15a.
  • detergent dispenser 7 of machine 1 comprises a spare container 21 ( Figures 6, 7 ), which fits firmly, but easily removably, to lid 9, in lieu of container 8, whenever bleaching, as opposed to prewashing, is required.
  • spare container 21 is the same design, externally, as container 8, i.e. is open on top to fit to lid 9, and comprises three different inner compartments for three different detergents.
  • container 21 comprises a central first compartment 22 for liquid softener; a second compartment 23 located on one side of first compartment 22, and for containing specific main-wash detergent; and a third compartment 24 located on the opposite side of first compartment 22 to second compartment 23, and for containing liquid bleach for bleaching the wash.
  • detergent dispenser 7 also comprises an additional siphon 27 located inside third compartment 24 to drain the liquid bleach from third compartment 24 into feed conduit 13 underneath.
  • siphon 27 comprises two sleeves, which fit one inside the other when lid 9 is fixed to container 21.
  • a first sleeve 27a is located inside third compartment 24, has a preferably, though not necessarily, circular cross section, and extends upwards from the bottom wall of third compartment 24, in a direction parallel to the mid-plane of container 21, so that its bottom end communicates with feed conduit 13, and its top end communicates with third compartment 24.
  • a second sleeve 27b of siphon 27 has a preferably, though not necessarily, circular cross section larger in outside diameter than first sleeve 27a, and is connected to lid 9 inside third opening 20.
  • the additional siphon 27, defined by engagement of sleeves 27a and 27b, advantageously provides for retaining the liquid bleach inside third compartment 24, which cannot be done in third compartment 12 of container 8, in which the liquid bleach would flow freely and uncontrollably through outlet 12a and straight into feed conduit 13 and tub 3.
  • unit 6 also comprises a known feed device 14 for selectively feeding water into each of compartments 10-12 or 22-24 of detergent dispenser 7; and an electronic control unit 28 for performing a number of wash programs selectable by the user on a control interface 29.

More specifically, the user may select at least one standard wash program, i.e. with no prewash or bleach stage; or a wash program comprising a prewash stage; or a wash program comprising at least one bleach stage.
  • electronic control unit 28 controls feed device 14, at least at the initial stage in the program, to feed water into third compartment 12 of container 8 of detergent dispenser 7 to flush the powdered prewash detergent into tub 3.
  • electronic control unit 28 provides, before at least one rinse stage in the wash program, for feeding water into third compartment 24 of container 21 of detergent dispenser 7 to flush the liquid bleach for the bleach stage into tub 3.
  • control interface 29 may be wired to allow user selection of the wash program comprising the prewash stage, or the wash program comprising the bleach stage.
  • Detergent dispenser 7 as described above may advantageously be used in a detergent dispenser unit 6 of a front-loading machine 1 having, for example, a recess formed specially in the casing to house detergent dispenser 7, or in a detergent dispenser 6 of a top-loading machine 1.
  • machine 1 is a top-loading machine having a top opening 30 for loading and unloading laundry in and out of tub 3, and which is formed in the top wall of casing 2 and closed by a door 31 hinged to casing 2.
  • detergent dispenser 7 is fitted directly to the lateral edge of opening 30.
  • containers 8 and 21 may comprise a number of external connecting tabs (not shown) which fit inside respective seats (not shown) formed in a lateral wall of opening 30, to fit container 8 or 21 firmly but easily removably to casing 2; and the ends of frame 15 of lid 9 are shaped to rest at least partly on two lateral-edge portions of opening 30.

  • electronic control unit 28 performs the wash program comprising the prewash stage, which corresponds to an initial stage in which water is fed into third compartment 12 to flush the water and powdered prewash detergent mixture into tub 3. After which, electronic control unit 28 feeds water into first compartment 10 and second compartment 11, according to the user-selected program.
  • the user substitutes second container 21 for first container 8, and fits second container 21 to lid 9 to form detergent dispenser 7; fits detergent dispenser 7 to machine 1; and pours softener, when desired, into first compartment 22, wash detergent into second compartment 23, and liquid bleach into third compartment 24.
  • electronic control unit 28 performs the wash program comprising the bleach stage, which may correspond to feeding water into third compartment 12, just before at least one rinse stage, to flush the water and liquid bleach mixture into tub 3.
  • the wash may be bleached by selecting a "standard" wash program comprising at least one stage in which water is fed into third compartment 12 before and/or during a rinse stage.
  • bleaching may be performed by simply pouring liquid bleach into third compartment 24 of dispenser 7, and selecting the standard wash program.
  • detergent dispenser 7 may also comprise a third siphon 33, which may be located inside second compartment 11 of first container 8 or second compartment 23 of second container 21 to retain liquid detergent inside second compartment 11 or 23. More specifically, like the first and second siphon 17 and 27, third siphon 33 may comprise two sleeves, which fit one inside the other when lid 9 is fixed to container 8 or 21.
  • a first sleeve 33a is located inside second compartment 11 or 23, has a preferably, though not necessarily, circular cross section, and extends upwards from the bottom wall of second compartment 11 or 23, in a direction parallel to the mid-plane of container 8 or 21, so that its bottom end communicates with feed conduit 13, and its top end communicates with second compartment 11 or 23.
  • a second sleeve 33b of third siphon 33 has a circular cross section, is preferably, though not necessarily, larger in outside diameter than first sleeve 33a, and is connected to lid 9 inside second opening 19.
  • the detergent dispenser described above has the major advantage of enabling the user to perform bleaching or prewash cycles by simply changing the dispenser container according to the selected cycle.
