Abstract:
The present invention provides a semiautomatic hydraulic water softener which is a water softener comprising: an ion resin tank (100) having ion resin; a regenerant container (200) in which a regenerant can be introduced in order to produce reclaimed water capable of filling the ion resin; a drain valve (293) provided on the regenerant container (200) in order to externally drain residual water; a water introducing part (400) for selectively supplying raw water to the ion resin tank (100) and the regenerant container (200); and a timer and a ceramic disk switching valve (300) for selecting one from among a water softening mode, a raw water mode, and a regenerating mode, and changing passages between the water introducing part (400), the ion resin tank (100), and the regenerant container (200). When the water softener is in regenerating mode, one from among a first mode and a second mode is selected according to a preset method, wherein the first mode is implemented during a preset time by the timer and ceramic disk switching valve (300), and when raw water is supplied to the regenerant container (200) to produce reclaimed water, the drain valve (293) is opened in the second mode.
