Definitions

  • the present invention relates to a laundry washing machine.
  • the present invention relates to a top-loading home laundry washing machine, to which the following description refers purely by way of example, without implying any loss of generality.
  • top-loading laundry washing machines generally comprise: a substantially parallelepiped-shaped, outer boxlike casing, typically structured for resting on the floor; a substantially cylindrical hollow washing tub which is typically suspended in floating manner inside the casing by means of a number of coil springs and shock-absorbers, with the longitudinal reference axis of the washing tub oriented substantially horizontally; a substantially cylindrical, hollow revolving drum which is structured for housing the laundry to be washed, and is housed in axially rotating manner inside the washing tub for rotating about its substantially horizontally-oriented, longitudinal reference axis; an elastically-deformable bellows which connects in watertight manner a pass-through opening provided on the upper section of the lateral wall of the washing tub to the annular rim (called also hopper) of a laundry loading/unloading pass-through opening provided on the top of the casing; and an upper door which is typically hinged to the top of the casing so as to rotate to and from a closing position in which the door rests on the top of
  • Known laundry washing machines of the above type furthermore typically comprise: an electric motor assembly which is located outside of the washing tub, and is structured for driving into rotation the revolving drum about its longitudinal reference axis inside the washing tub; a detergent dispenser which is usually attached to the annular rim (or hopper) of the laundry loading/unloading opening on the top of the casing, above the pass-through opening on the lateral wall of the washing tub; and a fresh water supply circuit which is structured for drawing fresh water from the water mains and supplying said water into the detergent dispenser so as to sweep away into the washing tub the detergent and/or softeners stored into the detergent dispenser.
  • a detergent dispenser of the above type is disclosed in European Patent Application No. 2133456 .
  • the detergent dispenser disclosed in European Patent Application No. 2133456 is optimized for operating with liquid-type detergents, while it has shown some problems with detergent powder.
  • detergent powder when detergent powder is poured into the detergent compartment of the detergent dispenser, it generally forms, on the bottom of the detergent compartment, a compact bed of detergent powder that usually completely clogs up the entrances of the siphon assembly of the detergent dispenser, thus hampering the correct draining of the mixture of water and detergent to the washing tub when the fresh water is subsequently poured into the detergent compartment.
  • EP2048275 discloses a laundry washing machine dispenser for detergent products or similar, comprising a vessel inserted in a removable manner into a dispenser bay in the laundry washing machine casing; the vessel being divided into a number of independent detergent compartments each of which is fillable with a detergent product, said dispenser also comprises an auxiliary stand-alone liquid detergent container which is capable to store a given amount of liquid detergent product, and is fittable in a removable manner into a first vessel detergent compartment; the stand-alone liquid detergent container comprises a basin which is dimensioned for being inserted in a removable manner into the first detergent compartment.
  • EP2377987 discloses a fabric treating appliance comprising: a treating chamber for receiving the fabric for treatment; a treating chemistry dispenser comprising: at least one cup with a bottom wall; a siphon tube projecting upwardly from the bottom wall and having an inlet opening above the bottom wall, with an inlet opening fluidly coupled to the treating chamber; a cover for the siphon tube; and a liquid distribution header located above the cover and having at least one of a first type of outlet opening configured to introduce a liquid stream into the cup from a position above and beyond a periphery of the cover and downwardly along a trajectory terminating below and within the periphery of the cover, wherein the liquid stream directly impinges a portion of at least one of the cup and siphon tube below the cover and a method of operating the fabric treating appliance.
  • the detergent dispenser is flushed with a water flow for removal of residual powder while reducing sudsing.
  • Aim of the present invention is to provide a detergent dispenser for top-loading laundry washing machines structured to correctly/efficiently operate with either liquid-type or powder-type detergents.
