Definitions

  • the present invention relates to a washing machine comprising a water softening device.
  • water softening devices are used for decreasing the hardness of the wash water and for providing an effective washing.
  • the water softening device comprises an ion exchanger and a salt container that provides the regeneration process to be performed by keeping the resin in the ion exchanger in salty water in the regeneration process.
  • the water used in washing is passed over the ion exchanger and is delivered to the tub to be included in the washing process.
  • the ion exchanger becomes unable to soften the water in the course of time therefore the regeneration process is performed by keeping it in the salt solution taken from the salt container at certain intervals.
  • the line carrying the residual water is connected to the discharge line at the lower side of the tub and the water is discharged from the discharge line by means of the pump without contacting the drum.
  • the line carrying the residual rinsing water also carries the soft water whereof the hardness is removed in the ion exchanger and the soft water is delivered to the tub by supplying through the discharge line.
  • regeneration water, generated after the regeneration process, from the ion removal means is performed through a passage connected to the drainage means.
  • the aim of the present invention is the realization of a washing machine comprising water softening device and wherein the corrosive residual water produced in the water softening process is prevented from
  • the washing machine realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a soft water line that connects the water softening device to the tub and that provides the residual water produced in the regeneration and rinsing process of the ion exchanger to be delivered to the tub such as to not contact the drum.
  • the soft water line is connected to the underside of the tub so as to be above the discharge hole level by extending from the ion exchanger to the tub. Water is delivered from the soft water line into the tub by means of an inlet opening whereto the soft water line is connected, opening to the gap between the tub and the drum at a level between the discharge hole and the lowermost point of the drum.
  • the soft water line is connected to the tub by means of a connection pipe that extends outwards almost horizontally from the cylindrical lower wall of the tub or the neck portion that extends by narrowing down towards the discharge hole.
  • the residual water passing through the connection pipe and flowing horizontally is directed to the discharge hole without contacting the drum inside the tub.
  • the washing machine comprises a barrier that forms an obstruction between the inlet opening and the drum by extending almost horizontally from the inner surface of the tub or from the neck portion underneath the tub towards above the discharge hole, and that prevents the water that comes gushing out from the inlet opening from contacting the drum.
  • the discharge pump starts operating some time before the rinsing process of the ion exchanger starts and provides the float to open the discharge hole before the rinsing process of the ion exchanger is started. Consequently, the instant the residual water washing the ion exchanger reaches the tub, the discharge hole is not closed by the float and the residual water is prevented from accumulating in the tub and contacting the drum.
  • the residual water with corrosive and rusting effect that is quite damaging for the drum and produced in the regeneration and rinsing processes performed for the water softening device is prevented from contacting the drum.
  • Figure 1 - is the schematic view of a washing machine.
  • Figure 2 - is the view of detail A in Figure 1.
  • the washing machine (1 ) comprises a tub (2) produced from plastic
  • the washing machine (1 ) of the present invention comprises
  • a soft water line (1 1 ) that is connected to the lower part of the tub (2) so as to be above the discharge hole (4) level by extending from the ion exchanger (8) to the tub (2) and which delivers the soft water produced in the ion exchanger (8) during the laundry washing process and the residual water that washes the resin in the ion exchanger (8) in the rinsing process after the regeneration process to the tub (2) and
  • the soft water line (1 1 ) is used in conveying both the soft water produced in the ion exchanger (8) and also the residual water that washes the ion exchanger (8) during the regeneration and rinsing processes.
  • the pump (5) does not operate during the laundry washing process and the float (7) closes the discharge hole (4) while soft water is received into the tub (2) from the ion exchanger (8).
  • the pump (5) operates in the resin rinsing process after the regeneration and the float (7) opens the discharge hole (4) whereby the residual water (2) received into the tub (2) is discharged to the outside by passing through the discharge hole (4) opened by the float (7).
  • the residual water contacting the tub (2) does not pose a risk since the tub (2) is produced from plastic.
  • the water received for the washing process is delivered to the ion exchanger (8) by means of the valves without being delivered directly to the tub (2) and the water of which its hardness removed in the ion exchanger (8) is transferred to the tub (2) by the soft water line (1 1). Since the pump (5) does not operate in the washing process, the discharge hole
  • the soft water received into the tub (2) fills the tub (2) and is used in the washing process.
  • salty water is received into the ion exchanger (8) from the salt container (9) and after waiting for some time, the rinsing process of the ion exchanger (8) is performed by the water received from the outside.
  • the residual water washing the ion exchanger (8) in the rinsing process is delivered to the tub (2) by using the soft water line (1 1 ).
  • the soft water line (1 1) is connected to the underside of the tub (2) at a level below the lowermost point of the drum (3), the residual water entering from the inlet opening (12) into the gap (G) between the tub (2) and the drum (3) is directed to the discharge hole (4) without contacting the drum (3), the float (7) is provided to open the discharge hole (4) by operating the pump (5) during the rinsing process and the residual water passing through the discharge hole (4) and the hose (6) is discharged outside by means of the pump (5).
  • the washing machine (1 ) comprises a connection pipe (13) that provides the soft water line (1 1 ) to be connected to the tub (2) and which extends almost in horizontal direction from the lower side or the neck (15) of the tub (2) towards the outside.
  • the water passing through the connection pipe (13) continues its flow in the horizontal direction and flows from the inlet opening (12) into the gap (G) between the tub (2) and the drum (3) and is directed to the discharge hole (4) without contacting the drum (3).
  • the washing machine (1 ) comprises a barrier (14) that forms an obstruction between the inlet opening (12) and the drum (3) by extending almost in horizontal direction from the inner surface or from the neck (15) portion of the tub (2) towards above the discharge hole (4) and which prevents the water that comes out of the inlet opening (12) from contacting the drum (3).
