Definitions

  • the present invention concerns a method of washing for washing machine.
  • US patent n° 3.388.410 describes a washing method which provides during the whole washing time, as also during the rinsing time, an alternation of cycles in which the drum containing the clothes to be washed, is made to rotate at high speed, with cycles during which the drum is made to rotate at a lower speed.
  • the high speed being sufficient to make the centrifugal force acting on the clothes overcome the force of gravity and maintain the ones against the drum wall, while during the cycles in which the drum is made to rotate a lower speed, the clothes fall back into the drum base itself.
  • the soapy washing solution or the rinsing water is taken from the base of the washing tub and is continuously fed again by spraying, by means of recirculation pump, into the drum.
  • recirculation pump a pump for recirculation
  • EP 0.726.349 describes a method of washing machine comprises at least one washing phase which includes a cycle of work at high speed and recirculation of water during which a drum containing the laundry to be washed and rotatory housed in a washing tub, is made to rotate at a first speed, sufficiently high to generate a centrifugal force which causes arrangement of the laundry along the periphery of the drum and, simultaneously, the water in the washing tub is taken from said tub and is returned therein by spraying at a central part of the drum.
  • a subsequent work cycle at low speed then takes place, during which the drum is made to rotate at a second speed, lower than said first speed and such as to allow remixing of the laundry, while the recirculation of water is substantially interrupted.
  • the cycle of work at high speed and recirculation of water has a duration limited to the time necessary for the complete removal of detergent from a detergent container and during its performance part of the water taken from the tub is made to pass through the container of detergent and subsequently reintroduced into the tub.
  • the quantity of water fed into the washing tub must be sufficient to ensure that, during the recirculation, a quantity of water remains always in the tub so as to prevent the cavitation of the recirculation pump. This is more likely to occur during the cycles of drum rotation at low speed.
  • the object of the present invention is to permit a good clothes distribution in the drum and performances improvement for washing in particularly in case of relation drum volume, clothes quantity small ; in order to adapt the drum volume for the same machine nominal garment to reduce consequently the energy and the water consumption to optimize the power of the washing machine motor.
  • fig 1 we can see on the diagram showing water level 1 and drum speed 2 that after a first wash period of about 57 minutes, the drum is subject to two brief impulses 11,12 in order to obtain laundry detachment.
  • the phase impulses 11,12 being followed by a washing phase 10 strictly speaking of about one hour duration until the rinsing phase.
