Title: 역삼투압 정수기의 필터교환 경보장치 및 그 방법
Filed: 1999-04-26
Abstract: 본 발명은 역삼투압 정수기의 필터교환 경보장치에 관한 것이다. 본 발명 정수기의 필터교환 경보장치는, 공급수의 오염도(TDS: total dissolved solids: 물 속에 용해된 총 고형물질)를 감지하기 위한 TDS 측정수단; 정수기가 동작할 때 승압펌프에 전원이 인가되는 것을 감지하는 승압펌프 동작감지수단; 필터의 교환시기나 오염, 단수 등의 경보를 시각 및 청각적으로 표시하여 주는 경보수단; 정수기의 이상경보 발생시 승압펌프의 전원을 제어해 주는 전원 제어수단; 그리고 상기 각 수단들에 접속되어 이들을 통제하고 제어하기 위한 마이컴으로 구성되어 있다. 본 발명에 의하면, 공급수의 오염도를 감안한 물의 정수량을 측정함으로써 보다 과학적이고 정확한 필터 교환시기를 판단하고 사용자에게 그 시기를 자동으로 알려주어 필터를 교환할 수 있도록 함은 물론 정수기의 동작중에도 공급수에 이상이 발생하였거나 오염이 심한 경우, 승압펌프로 인가되는 전원을 차단하여 정수기의 작동을 멈춤으로써 사용자에게 안전한 식수를 제공하고, 아울러 오염으로 인한 필터의 치명적인 손상을 방지할 수 있다.
