Abstract
A water softening device includes an electrolysis device, a first circulation flow path and a second circulation flow path, a first sensor, a second sensor, and a controller, wherein the controller controls the electrolysis device to execute a first mode in which the alkaline water is allowed to flow through the first circulation flow path and the acidic water is allowed to flow through the second circulation flow path, and a second mode in which the acidic water is allowed to flow through the first circulation flow path (8A) and the alkaline water is allowed to flow through the second circulation flow path, and controls to stop electrolysis by the electrolysis device based on a detection value of the first sensor or the second sensor in the first mode and the second mode.
