본 발명은 누수감지센서에 관한 것으로, 특히 필름 재질에 의해 테이프 형태로 길게 형성된 누수감지센서에 발열기능을 부가하여 누설된 물이 누수감지센서의 상부면에서 결빙되는 것을 방지하도록 한 누수감지센서에 관한 것이다.The present invention relates to a water leakage sensor, and more particularly, to a water leakage detection sensor which is provided with a heat generating function in a water leakage sensor formed in a tape form by a film material to prevent a leaked water from being frozen on the upper surface of the water leakage sensor .

등록특허 제10-1393074호에서는 베이스필름; 상기 베이스필름에 상기 베이스필름의 길이방향을 따라 나란하게 각각 형성된 전류전극과 저항전극을 포함하는 전극부; 상기 베이스필름과 전극부 상에 적층되고, 상기 전류전극의 일부가 노출되도록 타공된 제1 전극홀과 상기 저항전극의 일부가 노출되도록 상기 베이스필름의 길이방향을 따라 상기 제1 전극홀과 대응되는 위치에 타공된 제2 전극홀로 이루어진 전극홀 쌍이 복수 개 형성된 커버필름; 수분 흡수 재질로 이루어지고, 상기 복수 개의 전극홀 쌍 별로 상기 제1 전극홀과 제2 전극홀을 충진하며 연결시키도록 상기 커버필름 상에 개별적으로 코팅되는 복수 개의 수분흡수코팅층;을 포함하고, 상기 복수 개의 수분흡수코팅층 중 하나 이상에 수분이 침투되어 상기 전류전극과 저항전극이 통전되면 상기 전극부에 인가된 전류 값의 변화를 감지하여 누수 여부를 판별하는 필름형 누수감지센서를 제안하였다.Japanese Patent Registration No. 10-1393074 discloses a base film; An electrode portion including a current electrode and a resistance electrode formed on the base film in parallel with each other along the longitudinal direction of the base film; A first electrode hole laminated on the base film and the electrode portion, the first electrode hole being formed to expose a part of the current electrode, and the first electrode hole corresponding to the first electrode hole along a longitudinal direction of the base film, A cover film having a plurality of pairs of electrode holes formed of second electrode holes perforated at positions; And a plurality of water absorbing coating layers which are made of a water absorbing material and are individually coated on the cover film so as to fill and connect the first electrode holes and the second electrode holes for each of the plurality of electrode hole pairs, When the moisture penetrates into at least one of the plurality of water-absorbing coating layers and the current electrode and the resistance electrode are energized, a change in the current value applied to the electrode unit is sensed to determine whether leakage occurs.

그런데, 이러한 종래의 누수감지센서는 겨울철의 낮은 기온에 의해 누설된 물이 누수감지센서의 상부면에서 결빙되는 경우가 자주 발생한다.However, in such a conventional leak sensor, water leaked due to a low temperature in winter frequently occurs on the upper surface of the leak sensor.

이로 인하여, 누수된 물이 액체 상태로 존재하는 경우에 센싱의 감도가 좋아지지만, 결빙에 의하여 고체 상태로 존재하는 경우에는 센싱의 감도가 저하되어 센서의 신뢰성이 매우 저하되는 문제점이 있다. In this case, when the leaking water is present in the liquid state, the sensitivity of the sensing is improved. However, when the leaking water exists in the solid state due to freezing, the sensitivity of the sensing is lowered, and the reliability of the sensor is greatly reduced.

본 발명의 주된 목적은, 상기의 문제점을 해결하기 위하여 낮은 기온에서도 누설된 물이 센서의 상부면에서 결빙되지 않도록 하여 센싱의 감도를 높이도록 한 발열구조를 갖는 누수감지센서를 제공하는데 있다.SUMMARY OF THE INVENTION It is a principal object of the present invention to provide a leak detection sensor having a heat-generating structure for preventing leakage of water from the upper surface of the sensor even at a low temperature in order to increase the sensitivity of sensing.

이와 같이 구성된 본 발명을 첨부한 도면을 참조하여 상세히 설명한다.The present invention thus constructed will be described in detail with reference to the accompanying drawings.

도1은 본 발명에 의한 누수감지센서의 구조를 보인 도로서, 필름재질로 된 베이스층(100)의 상부면에는 길이방향으로 길게 한 쌍의 감지라인(110,120)이 서로 간격을 유지하면서 형성되는데, 이러한 감지라인(110,120)은 구리박판, 은 박판, 은과 카본 화합물 등 다양한 도전성의 갖는 재질로 형성된다.1 is a view showing a structure of a leakage sensor according to the present invention. A pair of sensing lines 110 and 120 are formed on an upper surface of a base layer 100, which is made of a film material, The sensing lines 110 and 120 are formed of a material having various conductive properties such as a copper thin plate, a silver thin plate, silver and a carbon compound.

상기 베이스층(110)의 상부면으로는 필름재질로 된 커버층(200)이 합지되며, 이러한 커버층(200)에는 상기 감지라인(110,120)이 형성된 위치와 대응되는 위치에 노출공(210,220)이 형성됨으로써 감지라인(110,120) 부분만 상부 외측으로 노출시키게 된다.A cover layer 200 made of a film material is laminated on the upper surface of the base layer 110. Exposed holes 210 and 220 are formed in the cover layer 200 at positions corresponding to the positions where the sensing lines 110 and 120 are formed. So that only the sensing lines 110 and 120 are exposed to the outside.

따라서 이러한 누수감지센서가 바닥에 길게 설치된 상태에서, 누수가 발생하게 되면, 상기 노출공(210,220)으로 물이 유입되어 감지라인(110,120)을 통전시키게 되고, 이로 인하여 두 감지라인(110,120)에서 저항값의 변화가 발생하며, 그 저항값의 변화에 의해 감지라인(110,120)과 연결된 컨트롤러에서 누수경보를 발생하게 되는 것이다.Therefore, when leakage occurs, the water is introduced into the exposure holes 210 and 220 to energize the sensing lines 110 and 120. As a result, the resistance of the sensing lines 110 and 120 increases, And a leakage alarm is generated in the controller connected to the sensing lines 110 and 120 due to a change in the resistance value.

한편, 누수감지센서의 상부면에서 물이 결빙되는 경우를 방지하기 위하여, 베이스층(100)의 하부면에는 발열구조가 구비되는데, 도2에서와 같이 구리박판으로 된 전극(130,140)이 베이스층(100)의 상부면에 형성된 감지라인(110,120)의 외측방향에 해당하는 위치에서 길이방향으로 나란히 부착된다.In order to prevent water from being frozen on the upper surface of the leak sensor, a heating structure is provided on the lower surface of the base layer 100. As shown in FIG. 2, Are aligned in the longitudinal direction at positions corresponding to the outward directions of the sensing lines (110, 120) formed on the upper surface of the substrate (100).

즉, 한 쌍의 감지라인(110,120)을 가운데 두고, 그 좌우 양측에 각각 전극(130,140)이 부착되며, 그 한 쌍의 전극(130,140)을 카본, 카본 블랙, 그래핀 등으로 된 저항성을 갖는 발열라인(150)에 의해 연결하게 되며, 이때 발열라인(150)은 사다리 형태로 일정간격을 가지면서 형성된다.That is, the electrodes 130 and 140 are attached to the left and right sides of the pair of sensing lines 110 and 120, respectively, and the pair of electrodes 130 and 140 are electrically connected to a pair of sensing lines 110 and 120, Line 150. At this time, the heating line 150 is formed with a predetermined distance in the form of a ladder.

이때, 감지라인(110,120)은 베이스층(100)의 상부면에 형성되고, 전극(130,240)과 발열라인(150)은 베이스층(100)의 하부면에 형성되므로 서로 간섭이 발생하지 않으면서 절연이 이루어 진다.Since the sensing lines 110 and 120 are formed on the upper surface of the base layer 100 and the electrodes 130 and 240 and the heating line 150 are formed on the lower surface of the base layer 100, .

한편, 베이스층(100)의 하측으로는 필름재질 또는 양면테이프로 된 하부절연층(300)이 합지되어 전극(130,240)과 발열라인(150)을 외부환경으로부터 절연시키게 된다.On the other hand, a lower insulating layer 300 made of a film material or a double-sided tape is laminated on the lower side of the base layer 100 to insulate the electrodes 130 and 240 and the heating line 150 from the external environment.

도3은 이러한 구조의 단면 구조를 보인 도로서, 감지라인(110,120)과 전극(130,140)에 전원을 공급하기 위하여 핀(P1,P2,P3,P4)이 연결된 상태를 보여주는데, 핀(P1,P4)는 커버층(200), 베이스층(100), 전극(130,140), 하부절연층(300)을 관통함으로써 전극(130,140)에 발열을 위한 전원을 인가하여 발열라인(150)이 발열하도록 한다.3 shows a state in which the pins P1, P2, P3 and P4 are connected to supply power to the sensing lines 110 and 120 and the electrodes 130 and 140 while the pins P1 and P4 A power source for generating heat is applied to the electrodes 130 and 140 by passing through the cover layer 200, the base layer 100, the electrodes 130 and 140 and the lower insulating layer 300 so that the heating line 150 generates heat.

이로인하여 누수감지센서의 상부면에 열이 전달되어 물의 결빙이 방지되는 것이다.As a result, heat is transmitted to the upper surface of the leak sensor to prevent freezing of water.

또한, 감지라인(110,120)에 연결되는 핀(P2,P3)도 커버층(200), 베이스층(100), 하부절연층(300)을 관통하여 누수 감지를 위한 전원을 공급하게 되는데, 이때 발열라인(150) 사이의 공간부위(S)에서 핀(P2,P3)이 관통하여 발열라인(150)과의 간섭이 발생하지 않는 것이다. The pins P2 and P3 connected to the sensing lines 110 and 120 also supply a power for sensing leakage through the cover layer 200, the base layer 100, and the lower insulating layer 300, The pins P2 and P3 pass through the space S between the lines 150 so that interference with the heating line 150 does not occur.
