Abstract
본 발명은 역삼투 필터에 압력을 가하는 가압 펌프와 급수용 밸브 또는 농축수 배수용 밸브의 동작을 원수공급상태에 따라 제어하여 가압 펌프 및 밸브들의 불필요한 동작을 방지하고 저수압 지역에서 물이 없는 상태에서 펌프가 공회전하는 문제를 해결할 수 있는 정수기의 원수공급상태 감지장치에 관한 것인 바, 그 특징은 수도물의 공급속도난 압력 및 유량등에 따라 다는 감지신호를 발생시키는 원수 공급상태 감지수단과, 정수 탱크내에 다수의 수위센서가 여러 높이로 구분 설치되어 정수 탱크내의 수위를 여러 단계로 구분하여 감지하기 위한 수위 감지수단과, 상기 원수공급상태 감지수단 및 수위 감지수단의 감지신호를 이용하여 공급원수의 유량이나 유속 및 유압에 따라 부하구동을 위한 각각의 제어신호를 출력하는 주제어수단과, 상기 주제어수단의 각각의 제어신호에 의해 각각의 릴레이를 제어하여 각 릴레이의 스위칭 접점에 연결된 부하를 구동하는 부하구동수단과, 정수기의 역삼투 필터 전단에 위치해 있으면서 상기 부하 구동수단에 연동하여 역삼투 필터가 동작 가능한 입력을 만들어주는 가압 수단과, 상기 가압수단의 압단에 위치하여 가압 수단이 오프시 그와 동시에 차단되어 원수 공급을 차단하고 가압수단이 동작될 경우 개방되어 원수 공급이 가능하도록 하는 급수 제어 수단으로 구성함에 있다.The present invention controls operation of a pressurizing pump for applying pressure to a reverse osmosis filter and a water supply valve or a concentrated water supply valve according to the raw water supply state to prevent unnecessary operation of the pressurizing pump and valves, The present invention relates to a raw water supply state sensing device for generating a sensing signal depending on a pressure, a flow rate, and the like of a supply speed of tap water, A water level detecting means for detecting a plurality of levels of water level sensors in the tank by dividing the water level in the purified water tank into a plurality of levels; A main control means for outputting respective control signals for driving a load in accordance with a flow rate, a flow velocity and an oil pressure, A load driving means for controlling each of the relays by respective control signals of the relay means and driving a load connected to the switching contacts of the relays; And a water supply control unit for controlling the flow of the raw water, which is opened when the pressurizing unit is operated and is shut off when the pressurizing unit is off, And the like.
