Water softener having timer control valve

摘要

A water pressure regenerated type water softener including: a timer control valve having a valve control unit rotated by a timer spring and into which raw water is supplied; a plurality of conduits into which the raw water selectively flows under the control of the timer control valve; a regeneration tank communicating with a regeneration tank inlet conduit of the conduits; and a resin tank unit receiving regeneration water flowing from the regeneration tank and containing an ion exchange resin therein. The water softener can be operated in one of stop mode, soft water mode, raw water mode and regeneration mode under the control of the valve control unit. When regeneration mode is selected, the valve control unit rotates to stop mode by the timer spring after a preset amount of time has elapsed.

1. A water softener system comprising:
a water softener; a timer spring; a timer control valve that receives raw water therein and is rotatable by the timer spring; a raw water inlet conduit through which raw water is supplied to the timer control valve, the timer control valve including:
a valve housing provided on the raw water inlet conduit,a lower valve body placed in the valve housing,an upper valve body rotatably placed on the lower valve body,an upper cap provided on an upper end of the valve housing, anda timer operated in conjunction with the valve housing; and a plurality of flow holes formed through the lower valve body, wherein the flow holes protrude upwards from an upper surface of the lower valve body, thus forming a valve step which is a gap between the upper valve body and the lower valve body, wherein each flow hole is selectively in fluid communication with the raw water inlet conduit, and wherein each flow hole is bounded by a protuberance spaced from other protuberances of the plurality of flow holes.
