Definitions

  • the present invention concerns the field of laundry washing techniques.
  • the present invention refers to a method for washing laundry in a laundry washing machine capable of performing a more efficient detergent dissolution.
  • laundry washing machines both "simple” laundry washing machines (i.e. laundry washing machines which can only wash and rinse laundry) and laundry washing-drying machines (i.e. laundry washing machines which can also dry laundry), is widespread.
  • Laundry washing machine will refer to both simple laundry washing machines and laundry washing-drying machines.
  • Laundry washing machines generally comprise an external casing provided with a washing tub which contains a rotatable perforated drum where the laundry is placed.
  • a loading/unloading door ensures access to the drum.
  • Laundry washing machines typically comprise a water inlet circuit and a products supply unit for the introduction of water and washing/rinsing products (i.e. detergent, softener, etc.) into the tub.
  • water and washing/rinsing products i.e. detergent, softener, etc.
  • Known laundry washing machines are also provided with water draining devices that may operate both during the initial phases of the washing program and at the end of the same to drain the dirty water.
  • a complete washing program typically includes different phases during which the laundry to be washed is subjected to adequate treatments.
  • a washing cycle usually comprises a laundry wetting phase with addition of a washing detergent and a main washing phase during which the drum is rotated and the water contained therein is heated to a predetermined temperature based on the washing program selected by the user.
  • the drum is rotated, so as to apply also a mechanical cleaning action on the laundry.
  • the drum is typically rotated at high rotational speed, in such a way that dirty washing liquid (i.e. water mixed with detergent) is extracted from the laundry, and this dirty washing liquid is drained by the water draining devices.
  • a successive step of the cycle typically comprises a rinsing phase which usually comprises one or more rinsing cycles.
  • clean rinse water is first added to the laundry, so as to be absorbed by the laundry and remove from the latter detergent and/or dirty particles not previously removed by washing liquid, and then the drum is rotated to extract water and dirty particles/detergent from the laundry: the dirty water extracted is drained from the tub to the outside by the water draining devices.
  • a final spinning phase allows the extraction of the residual water contained in the wet laundry.
  • the water extracted during the spinning phase is drained towards the outside by means of the water draining devices (during or after the spinning phase).
  • a laundry washing machine performing a washing program is disclosed in document EP0464776 .
  • Such laundry washing machine comprises a tub having a cylindrical structure for containing washing water and a rotary drum rotatably installed in the tub.
  • the machine further comprises a heater for heating washing water.
  • the heater is installed in the lower portion of the tub.
  • the machine further comprises a recirculating circuit provided with a recirculating pump which withdraws liquid from the bottom of the tub and re-admits said liquid into the tub.
  • a drawback posed by the laundry washing machines of the known art lies in that the washing products, or the rinsing products, which are introduced into the washing tub during the washing program, move towards the bottom part of the tub, due to their high density and, therefore, tend to accumulate on the bottom of the tub below the heater.
  • washing performance may be different for each washing program depending on the percentage of product which accumulates on the bottom of the tub and hence does not completely dissolve.
  • the washing performance may vary from time to time and cannot be properly controlled.
  • the object of the present invention is therefore to overcome the drawbacks posed by the known technique.

  • the present invention relates, therefore, to a method for washing laundry in a laundry washing machine of the type comprising:
  • the threshold level is set at the lower point of the washing tub.
  • the threshold level is set at the lower point of a seat of the washing tub which receives the heater device.
  • the quantity of liquid in said phase of introducing a quantity of liquid into the washing tub which improves the dissolution of the washing/rinsing product is fresh water coming from the water supply circuit.

  • the method provides for repeating a determined number of times the steps of activating the recirculation circuit, deactivating the recirculation circuit and introducing a quantity of liquid into the washing tub.
  • the determined number of times is two or more times.
  • the determined number of times depends on the amount and on the absorption characteristics of the loaded laundry.
  • the method further comprises an auxiliary recirculating phase suitable for recirculating liquid at the bottom of the washing tub so as to further improve the dissolution of the washing/rinsing product collected therein.
  • the method provides for switching-off the heater device when the liquid level inside the washing tub is below the heater device.
