본 고안은 정수필터에 관한 것으로, 특히 정수필터의 수명을 체크하기에 적당하도록한 징수필터 교환시기체크회로에 관한 것이다.The present invention relates to a water filter, and more particularly, to a collection filter replacement timing check circuit adapted to check the life of a water filter.

정수필터를 오랫동안 사용하면 물에 함유된 각종 불순물이 정수필터에 걸려 정수구멍에 막히게 되어 정수필터를 통해 나오지 못하게 되는데, 종래에는 이와같은 막힘 상태 및 정수필터를 통해 나오는 물의 양을 사용자가 모르기 때문에 정수필터의 교환시기를 모름은 물론 정수필터 막힘에 의하여 정수된 물이 제때에 공급할 수 없게되는 문제점이 있었다.If the water filter is used for a long time, various impurities contained in the water get caught in the water filter and become clogged in the water purification hole so that it does not come out through the water filter. Conventionally, the user does not know the clogging state and the amount of water through the water filter. Not only do not know the replacement time of the filter, there was a problem that the purified water can not be supplied in a timely manner by clogging the water filter.

이에 따라 본 고안은 상기한 문제점을 제거하기 위한 것으로써, 제1도에 도시된 바와 같이 수위감지 신호(d)에 의해 결정되는 전위(b)와 기준전위(a)를 비교하는 비교기(11)로 이루어진 필터교환시기 감지부(10)와, 상기 감지부(10)의 출력을 인가받아 LED(21)를 동작시키는 발진IC(20)로 구성되며, 제2도는 본 고안에 적용된 수위조절 장치 회로로써, 1990년 5윌 31일자로 출원된 실용신안 등록 출원 제7573호 "냉수기의 수위 조절장치"이다.Accordingly, the present invention is to eliminate the above-described problem, and as shown in FIG. 1, the comparator 11 for comparing the potential b determined by the water level detection signal d with the reference potential a It consists of a filter replacement time detection unit 10 and the oscillation IC 20 to operate the LED 21 by receiving the output of the detection unit 10, Figure 2 is a water level control device circuit applied to the present invention For example, Utility Model Registration No. 7573, filed on May 31, 1990, entitled "Water level control device for chilled water".

상기 실용신안 등록출원 제7573호 "냉수기의 수위 조절장치"는 저고 수위 센서(16, 17)에 의해 물탱크(9)내의 수위를 감지하여 저고수위 조절부(200)(300)를 통해 전기적 급수 제어변(26)을 제어함으로써 물탱크(9)내의 수위를 일정하게 유지시켜주는 회로이다. 여기서 미설명부호 100은 전원부이다.The Utility Model Registration No. 7573, "Water level control device for chilled water", detects the water level in the water tank 9 by the low water level sensors 16 and 17, and then the electric power through the low high water level control unit 200, 300. It is a circuit which keeps the water level in the water tank 9 constant by controlling the water supply control valve 26. Reference numeral 100 is a power supply unit.

따라서 제2도에 도시된 냉수기의 수위조절 장치를 참고로 본 고안에 따른 정수필터 교환시기 체크회로의 동작상태 및 작용, 효과를 상세히 설명하면 다음과 같다.Therefore, with reference to the water level control device of the chiller shown in FIG. 2 will be described in detail the operation state, operation, and effect of the water filter replacement time check circuit according to the present invention.

제1도에서 트랜지스터(Q0)의 베이스측 단자에 인가되는 수위감지신호(d)는 제2도에서 인가된다.In FIG. 1, the water level detection signal d applied to the base terminal of the transistor Q0 is applied in FIG. 2.

즉 물탱크(9)에 유입되는 물의 수위를 감지하는 저수위 감지센서(16)는 물탱크(9)에 유입된 물이 저수위감지센서(16)까지 차있지 않으면 저수위 조절부(200)와 오아게이트(103) 및 노아게이트(104,105)를 통해 C점에는 높은 전위가 인가되어 인버터(106)의 출력단(d)에는 낮은 전위가 되어 릴레이(107)에 전위가 걸리므로 릴레이의 접점이 f에서 g로 동작되어 전기적 급수 제어변(26)을 동작시키므로 물탱크(9)에 물이 유입된다.That is, the low water level sensor 16 for detecting the water level of the water flowing into the water tank 9 is the low water level control unit 200 and the oar gate if the water introduced into the water tank 9 is not filled to the low water level sensor 16. Through the 103 and the noar gates 104 and 105, a high potential is applied to the point C, and a low potential is applied to the output terminal d of the inverter 106 so that a potential is applied to the relay 107. The water is introduced into the water tank 9 because it is operated to operate the electric water supply control valve 26.

이때 d점의 낮은 전위는 제1도에서 트랜지스터(Q0)의 베이스측 단자(d)에 인가되어 트랜지스터(Q0)가 도통하지 않게되어 콘덴서(C2)가 저항(R4)을 통하여 충전하게 되어 b점의 전위가 높아지고, 일정시간이 지나도 물탱크(9)에 물이 차지 않으며 이전위는 기준 설정전위 점 a의 전위보다 높아지게 되어 비교기(11)의 출력단자는 로우상태가 된다.At this time, the low potential at the point d is applied to the base-side terminal d of the transistor Q0 in FIG. 1 so that the transistor Q0 is not conducted so that the capacitor C2 is charged through the resistor R4. The potential of H increases and the water tank 9 does not occupy water even after a certain time, and the previous potential becomes higher than the potential of the reference set potential point a so that the output terminal of the comparator 11 becomes low.

따라서 다이오우드(D1)는 도통하지 않아 발진부의 저항(R1,R2)과 콘덴서(C1)의 시정수에 의해 발진IC(20)가 발진하게 되고, 발진부가 발진하게 되면 발진IC(20)의 출력에는 일정한 주기의 구형 펄스가 출력되어 정수필터의 교환시기를 알려주는 LED(21)가 점멸하여 정수필터의 교환시기를 알려준다.Therefore, the diode D1 does not conduct, and the oscillation IC 20 oscillates by the time constants of the resistors R1 and R2 of the oscillation unit and the capacitor C1. When the oscillation unit oscillates, the output of the oscillation IC 20 A rectangular pulse of a certain period is output and the LED 21 indicating the replacement time of the water filter flashes to indicate the replacement time of the water filter.

여기서 콘덴서(C2)의 충전은 트랜지스터(Q0)의 베이스측 단자(b)에 높은 전위가 인가되면 충전은 중지되고 방전이 된다.Here, the charging of the capacitor C2 is stopped when the high potential is applied to the base side terminal b of the transistor Q0.

그리고 트랜지스터(Q0)의 베이스(d)의 전위는 물탱크(9)내의 수위감지부인 저수위 감지부(16)까지 물이 차지 않으면 C점의 전위는 하이전위가 되어 d점에는 로우전위가 된다.When the potential of the base d of the transistor Q0 is not charged to the low water level detecting unit 16, which is the water level sensing unit in the water tank 9, the potential at the point C becomes a high potential and becomes a low potential at the d point.

또한 정수필터 교환시기는 저수위 감지센서(16)에서 고수위 감지센서(17)까지 물이 채워지는 일정시간을 설정하여 체크를 하게된다.In addition, the water filter replacement time is checked by setting a predetermined time that water is filled from the low water level sensor 16 to the high water level sensor 17.

이와같이 본 고안에 따른 정수필터 교환시기 체크회로는 정수기에서 정수필터의 수명 체크 및 사용유무를 알려줌으로서 제품의 사용편리성 및 필터교환 시기를 알 수 있는 효과를 갖는다.Thus, the water filter replacement time check circuit according to the present invention has an effect of knowing the convenience of use of the product and the filter replacement time by notifying the life of the water filter in the water purifier and whether or not it is used.
