To provide a water softening device capable of controlling the anode usage time of each electrode in the electrolyzer to the same degree by making the electrolyzer feed destination switchable.SOLUTION: A water softening device 1 includes a water softening tank 3, a neutralization tank 4, an electrolysis tank 9, and a control unit 15. The electrolytic tank 9 has a first chamber 81 in which acidic electrolytic water is generated during positive operation and a second chamber 82 in which alkaline electrolytic water is generated during positive operation, and has at least two operating states during the regeneration process, including a positive operation and a reversed operation in which the polarity of the electrodes is reversed from the positive operation. The control unit 15 determines the destination of the electrolytic water delivered from the first chamber 81 and the electrolytic water delivered from the second chamber 82 based on the operating state of the electrolysis tank 9 during the regeneration process.SELECTED DRAWING: Figure 1 【課題】電解槽の送出先を切り替え可能な構成とすることで、電解槽の各電極の陽極使用時間を同程度に制御することが可能な軟水化装置を提供すること。【解決手段】軟水化装置１は、軟水槽３と、中和槽４と、電解槽９と、制御部１５と、を備える。電解槽９は正運転時に酸性電解水が生成される第一室８１と、正運転時にアルカリ性電解水が生成される第二室８２と、を備え、再生工程時の運転状態として、正運転と、正運転とは電極の極性を反転した状態で運転する反転運転の少なくとも２種の運転状態を有する。制御部１５は、再生工程時に電解槽９の運転状態に基づいて、第一室８１から送出される電解水及び第二室８２から送出される電解水の送出先を決定する。【選択図】図１
