Title:
WATER-SOFTENING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/248599
Kind Code:
A1
Abstract:
A water softening device (1) comprises a water softening tank (3), a neutralizing tank (4), an electrolyzing tank (9), and a control unit (15). The electrolyzing tank (9) comprises: a first chamber (81) in which acidic electrolytic water is generated during normal operation; and a second chamber (82) in which alkaline electrolytic water is generated during normal operation. Operation states in a regeneration step include at least two types of operation states, namely, normal operation, and reverse operation in which the polarities of electrodes are reversed from those in the normal operation. The control unit (15) determines, on the basis of an operation state of the electrolyzing tank (9) in the regeneration step, a destination to which the electrolytic water sent from the first chamber (81) and the electrolytic water sent from the second chamber (82) are each sent.
