    • D06F39/007—Arrangements of water softeners

Definitions

  • the invention relates to a washing machine according to the preamble of claim 1.
  • a washing machine which is equipped with a softening device.
  • the additional installation of a softener makes it possible to carry out the wash cycles with soft water and the rinse cycles with hard water. If soft water is available for the washing process, this has the advantage that a smaller amount of detergent can be used. Especially in areas that have very hard tap water, equipping the washing machine with a softener would be desirable.
  • the invention has for its object to provide a washing machine in which the parts necessary for the softening device can be integrated into an existing washing machine concept within the housing and that the user is still easy to use and add the treatment agent Additional precautions are to be taken in order to achieve a further reduction in the detergent used.
  • the washing machine designed according to the invention is also characterized by a particularly economical use of detergent. No detergent can get into the drain system unused during the induction process.
  • the water supply to the machine is controlled by the solenoid valves (1) for cold water and the solenoid valve (2) for hot water from the program switch.
  • the water chamber (3), the softener (4) and the salt vessel (5) are to be counted as essential for the softening device.
  • the water chamber (3) is provided with an integrated back suction prevention.
  • the water chamber (3) can serve as a water pre-storage tank (gravity principle) or as a flow tank (time control principle).
  • the tub (6) of the machine receives the laundry drum (7) and is connected to the drain pump (9) via the tub drain (8).
  • the detergent is added via the dispenser drawer (10).
  • the softener (4) is connected to the induction bowl (10) via a line ( 1 1).
  • a branch (12) is interposed in this line ( 1 1), from which a connecting line (13) leads to the drain pump (9).
  • the softener ( 4 ) and the set vessel (5) are connected to the water chamber (3) in the usual way via lines (14 and 15).
  • the filler neck (16) for the salt vessel (5) is guided up to the upper lid area of the machine, and is preferably accessible to the user in the vicinity of the feed box (10).
  • a buoyancy body (23) arranged in the tub drain (8) is arranged.
  • a water reservoir (25) is formed in the drain line (24), which is attached inside the machine housing at a location above the usual water level of the tub (6)
  • the washing process is carried out with soft water.
  • waxy or cold Wasaer or both are mixed and fed via the line (19) into the water chamber (3).
  • a water reservoir forms in this water chamber (3) and the softener (4) is acted on via the line (14).
  • the soft water leaves the softener via the lines (17, 11) and is fed into the dispenser drawer (10), where the detergent for the pre-wash or main wash and rinsed into the tub (6).
  • Rinsing of the regenerated softener (4) is initiated by pumping out after the last rinse.
  • fresh water flows through the line (19), the water chamber (3) and the line (14) through the softener (4) and presses the regeneration solution via the line (11) and the induction bowl (10) into the machine outlet.
  • the softener is now available for the next soft water withdrawal of the subsequent wash cycle.
  • valve arrangements that control the correct water path in the intended function can be switched on automatically or by the program switching mechanism.
  • a water hardness switch (21) on the water chamber (3) allows adjustment for different hardness ranges.
  • the water chamber (3) is connected with a ventilation line (22) to the water inlet system of the machine for the purpose of ventilation.
  • the water supply to the water chamber (3) is controlled in the wash cycle via the magnetic valves (1 and / or 2).
  • the hard water is fed into the softener (4) in order to be fed from there as soft water via the line (11) and the open valve (26) into the induction bowl (10).
  • the valve - (27) is closed in the connecting line (13).
  • the detergent required for the washing process is flushed from the dispenser box (10) into the tub (6).
  • the drain opening of the tub (6) is closed by the buoyancy body (23).
  • no detergent can get into the drain unused, so that smaller amounts of detergent can be dosed.
  • the amount of water required for regeneration is made available by a magnetic valve (1) being activated via a line (29) (15) optionally crimped into the set container (5) via a valve (20) (not shown here), which is also provided. From there, the brine then reaches the softener (4).
  • the regeneration solution is passed through the water line via the connecting line (13) to the drain pump (9).
  • the valve (27) is open and the valve (26) is closed.
  • the valve (27) is switched on simultaneously with the drain pump (9), so that the regeneration solution rinsed out of the softener (4) is immediately conveyed out of the machine via the drain (28).
  • valve (27) can also be designed as a 3-way valve in order to either open or close the line - (13) or line (11). This design serves the same purpose as the arrangement shown in FIG. 2.
