Definitions

  • the present invention relates to a washing machine wherein the increase of foaming is prevented during the washing cycles.
  • the object of the present invention is to design a washing machine wherein the excessive foam formed in the washing process is effectively removed.
  • the foam that is formed in the tub is doused through spraying water between the tub and the drum by means of a spray arm disposed between the tub and the drum.
  • the water sprayed through the holes arranged on the spray arm disperses (diffuses) into the space between the tub and the drum and thus the foam is effectively doused.
  • some amount of the clean water received into the machine is delivered to the spray arm for dousing the excessive foaming formed in the tub.
  • the water collected under the foam formed in the lower region of the tub during washing is delivered to the spray arm by means of a circulation pump for clearing up the excessive foaming formed in the tub.
  • At least one orifice is provided at the upper suriace of the tub for receiving water into the tub and delivering to the spray arm
  • the drive required for the rotation of the spray arm is provided by a motor situated on the tub.
  • the spray arm used in another embodiment of the present invention is configured to rotate with the moment that results from the hydrostatic force by means of the arrangement and sizes of the holes provided thereon without requiring a separate drive element.
  • a foam sensor is used to detect excessive foaming in the tub.
  • Figure 1 - is the front schematic view of an embodiment of the present invention.
  • Figure 2 - is the sideways schematic view of another embodiment of the present invention.
  • the washing machine (1) comprises a drum (2) wherein the laundry is emplaced, a tub (3) inside which the drum (2) rotates, at least one orifice (4) for receiving water (S) into the tub (3) and a spray arm (5) that is secured to the tub (3) between the tub (3) and the drum (2), so as to be lacing the orifice (4), spraying the water delivered from the orifice (4) into the tub (3) for effectively dousing the foam.
  • the spray arm (5) has a hollow structure and comprises more than one hole (8) for spraying the water filled therein into the tub (3) The spray arm (5) rotates around the point it is secured on the tub (3)
  • the washing machine (1) furthermore comprises an inlet conduit (6) that delivers water to the orifice (4)
  • the orifice (4) is preferably situated at the upper portion of the tub (3)
  • the water received from the main supply can either be delivered directly or through the detergent dispenser to the inlet conduit (6) or it is also possible to reroute the water collected in the lower region of the tub (3) to the inlet conduit (6) for redelivering onto the tub (3)
  • the washing machine (1) comprises a circulation pump (7) for rerouting the water collected in the lower region of the tub (3) to the inlet conduit (6) from the tub (3)
  • the water (S) coming from the orifice (4) situated on the tub (3) fills the spray arm (5), passes through the holes (8) on the spray arm (5) and disperses into the tub (3) impinging on the walls of the tub (3) and the drum (2)
  • Some of the water (S) flows from these impinged surfaces to proceed into the lower portion of the tub (3) with the effect of gravity while some of it fills the drum (2) by passing through the holes on the drum (2)
  • the foam (K) collected on the tub (3) walls and in between the tub (3) and the drum (2) is carried away with it to the lower portion of the tub (3) and doused.
  • the washing machine (1) comprises a motor (9) for providing the drive required for rotating the spray arm (5)
  • the spray arm (5) is configured to rotate with the moment that results from the hydrostatic force by means of the arrangement and sizes of the holes (8) provided thereon, without requiring a separate drive element.
  • the washing machine (1) comprises a foam sensor for detecting the formation of excessive foam (K) and a control unit that activates or deactivates and controls the speed of the spray arm (5) depending on the data determined by the sensor.
  • K excessive foam
  • B/ means of the washing machine (1) of the present invention the overflowing of the foam during spin-drying is prevented by effectively dousing the foaming formed in the tub (3) Consequently, the rinsing performance is increased and residual detergent streaks remaining on the laundry at the end of washing is prevented.
