Definitions
- the aim of the present invention is the realization of a washing machine wherein the regeneration of the water softening member provided in the water softening unit is efficiently performed.
- the washing machine comprises a discharge receptacle.
- the discharge receptacle is connected to the water softening unit through a first waste water line.
- the control unit enables the brine in the water softening unit to be transferred into the discharge receptacle through the first waste water line.
- the discharge receptacle is connected to a discharge outlet which opens to the outside of the washing machine through a discharge line. Thus, the water in the discharge receptacle is enabled to be discharged.
- the washing machine (1) comprises a tub (2) which is suitable for performing the washing process therein; a water receptacle (3) which is connected to the water inlet (20) through which the mains water is supplied via a water inlet line (21); a water softening unit (4) which is suitable for receiving a water softening member which reduces the hardness of the washing water to be used in the washing process; a water softening line (5) which extends between the water softening unit (4) and the water receptacle (3) and which enables the water in the water receptacle (3) to be delivered to the water softening unit (4); a soft water line (6) which provides that the washing water with reduced hardness after passing through the water softening unit (4) reaches the tub (2); a salt box (8) which is connected to the water softening unit (4) by means of a regeneration line (7) and which is suitable for receiving the salt used in the regeneration of the water softening member; a water delivery line (9) which extends between the water receptacle (3)
- the water receptacle (3) can be a receptacle or a water hose which allows water to pass through.
- the control unit (10) directs the water taken into the washing machine (1) by controlling the valves (not shown in the figures) or pumps (not shown in the figures) on the lines.
- the washing water delivered to the tub (2) is passed through the water softening unit (4) and transferred to the detergent dispenser (15).
- the washing water is then transferred from the detergent dispenser (15) to the tub (2).
- the hardness level of the washing water to be delivered into the tub (2) is reduced. Consequently, the stain removal performance of the washing water is increased.
- an energy-saving washing machine (1) is realized since the same stain removal performance can be achieved with less water and detergent usage.
