    • PROBLEM TO BE SOLVED: To provide a washing machine on which a water softening device allowing continuous use of an ion exchange material without the need of replenishing a special agent by a user is mounted. SOLUTION: The washing machine includes: water softening means 5 in which a weak acidic cation exchange material having a weak acidic cation exchange group of pH 7.5 or more at a point of zero charge is filled between a washing tub 1 and water supply means 3, and pH decrease means 7 for preparing weak acidic to neutral water between water supply means 3 and the water softening means 5. The hardness of supplied city water is lowered by the water softening means 5, it is introduced into the washing tub 1 and supplied for washing, the weak acidic to neutral water generated by operating the pH decrease means 7 is introduced into the water softening means 5 after the end of the water supply, and thus hard water contents are separated from the weak acidic cation exchange material. Thus, the water softening device capable of regeneration without need of replenishing a special agent for regeneration by a user is achieved. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供一种洗衣机,其上可以连续使用离子交换材料的水软化装置,而不需要用户补充特殊的药剂。 解决方案:洗衣机包括:水软化装置5,其中在零充电点处具有pH 7.5或更低的弱酸性阳离子交换基团的弱酸性阳离子交换材料填充在洗涤桶1和水供应 装置3,以及用于在供水装置3和水软化装置5之间制备弱酸性至中性水的pH降低装置7.通过水软化装置5降低供水城市用水的硬度,将其引入洗涤桶1 供给洗涤后,通过操作pH降低装置7产生的弱酸性至中性水在供水结束后引入水软化装置5,因此将硬水含量与弱酸性阳离子交换材料分离。 因此,可以实现能够再生的水软化装置,而无需补充用户再生用的特殊剂。 版权所有(C)2011,JPO&INPIT
