An ion removes provided between a feed water valve for supplying water to an outer tub and a detergent supply case and an upper portion from the outer tub includes a cylindrical vessel in which sodium type strong acid positive ion exchange resin is filled up, a salt water vessel provided above the cylindrical vessel, and a salt vessel provided in the salt water vessel for receiving salt to enable plural regeneration of an ion exchange resin. Salt from the salt vessel is dissolved in water supplied to the salt water vessel and salt water having a concentration of about 10% is generated. After completion of every washing feed water cycle and every rinsing feed water cycle with an interval, the salt water is caused to flow into the ion exchange resin and the ion exchange resin is automatically regeneration-processed.
In a washing machine having a washing tub for receiving a washing matter and for carrying out a washing, a feed water means for supplying water to said washing tub, a regeneration means for regenerating an ion removal means disposed for regenerating ions contained in the water supplied by said feed water means, and a drainage means for discharging water from an inner portion of said washing tub, the washing machine characterized in that
