摘要：
Disclosed herein are an electrochemical softening apparatus that is relatively convenient and inexpensive and a washing machine including the same. The softening apparatus regenerates a zeolite compound that has been used to perform ion exchange using hydrogen ions (H+) generated using an electrochemical method such that the zeolite compound is repeatedly used. Hydrogen ions (H+) generated during a re-softening process are used to remove contaminants due to microorganisms and a scale component. The softening apparatus includes a regeneration unit to generate regeneration water containing hydrogen ions (H+) and a softening unit, including an Ion exchange material regenerated by the regeneration water, to convert raw water containing a hardness component into soft water containing hydrogen ions (H+).
