Definitions

  • the present invention relates to a washing machine comprising a lifter for regulating the flow of water.
  • the lifter In washing machines, the lifter is used for performing a more efficient washing process in the drum by tumbling the laundry. Moreover, by means of nozzles provided on the lifter, the water coming from the tub is sprayed onto the laundry. Failing to deliver the water through each nozzle at the same flow rate and regularity prevents every region of the laundry from being equally washed and causes the laundry to get damaged.
  • the delivery of the water coming from the tube to the tub onto the laundry with a high pressure via the nozzles on the lifter in the drum causes the laundry to get damaged with the effect of the pressure.
  • European Patent Document No. EP1876282 laundry washing and drying machines are disclosed, comprising paddles with different surface structures and geometry for better tumbling and washing the laundry in the drum. Also KR100627908B1 , US2005/252253A1 , JPS5977893A and EP1502982A2 concern washing machines.
  • the aim of the present invention is the realization of a washing machine comprising a lifter for regulating the flow of the water in the washing cycle.
  • the present invention concerns a washing machine according to claim 1.
  • the nozzles are arranged on the base, namely the region remaining between the side walls and the concave walls of the reservoir.
  • Each nozzle is encircled by a barrier in the form of an elevation from the base of the reservoir in order to ensure that the water accumulates on the base of the reservoir and flows into the drum after gaining a certain potential energy.
  • the flow starts after the water reaches a level as much as the height of the barrier from the base of the reservoir.
  • a washing machine comprising a lifter wherein the water is sent into the drum through each nozzle at the same flow rate.
  • the washing machine (1) comprises a body (2); a loading port (3) which is provided on the body (2); a drum (4) which is disposed in the body (2) and wherein the laundry is loaded via the loading port (3); a tub (5) wherein the drum (4) is disposed; a pipe (6) which provides the delivery of the water to the tub (5) during the washing cycle; and a lifter (7) which is disposed in the drum (4), which tumbles the laundry and which has at least one nozzle (8) for delivering the water into the drum (4) and a base (10) whereon the nozzle (8) is arranged.
  • the washing machine (1) of the present invention comprises the lifter (7) having a reservoir (9) comprising four walls (11, 13) which surround the nozzles (8) and which enable the water to flow into the drum (4) with a regulated flow as a result of the pressure formed by the accumulation of the water on the region of the base (10) where the nozzles (8) are arranged.
  • At least one lifter (7) is provided for delivering the water received into the tub (5) by means of the pipe (6) from the water mains onto the laundry loaded into the drum (4) via the loading port (3).
  • Said lifter (7) ensures that the laundry is tumbled during the washing process and the water is delivered onto the laundry in the drum (4) through the nozzles (8) arranged on the base (10).
  • the reservoir (9) comprises the four walls (11, 13) which surround the nozzles (8) arranged on the base (10) at the inner volume of the lifter (7) which receives the water coming from the drum (4).
  • the washing machine (1) comprises the lifter (7) comprising the reservoir (9) having two side walls (11) and two concave walls (13) joining the side walls (11).
  • the reservoir (9) volume formed by the concave walls (13) and the side walls (11) enables the water to be accumulated at a region closer to the nozzles (8) and to be centered more quickly.
  • the washing machine (1) comprises the lifter (7) having an opening (12) which is provided on the side wall (11) and/or the concave wall (13) for facilitating the water flow into the reservoir (9).
  • a guiding path is formed which enables the water to be accumulated in the reservoir (9) even if the water received by the lifter (7) flows to a region away from the nozzles (8).
  • the washing machine (1) comprises the lifter (7) having a barrier (14) which encircles the nozzle (8) and which enables the water to flow into the drum (4) through every nozzle (8) at the same time and the same flow rate.
  • the barriers (14) By encircling the nozzles (8) by means of the barriers (14) in the form of an elevation from the base (10) of the reservoir (9), the water received by the lifter (7) flows into the drum (4) through the nozzles (8) after reaching a level as much as the height of the barrier (14) in the reservoir (9).
  • the water flows through every nozzle (8) at the same time and the same flow rate.
  • a washing machine (1) is realized, wherein the water is delivered into the drum (4) from the lifter (7) in a regulated manner during the washing process.
