Description

엔진 냉각시스템의 이상 발생 감지장치Malfunction detection device of engine cooling system

본 발명은 엔진 냉각시스템의 이상 발생 경보장치에 관한 것이다.The present invention relates to an alarm system for an abnormal occurrence of an engine cooling system.

실린더블록(1)과 실린더헤드(2)는 고온의 연소열에 노출되어 있어 과열에 의한 손상을 방지하기 위하여 제2도에 도시하는 것과 같이 워터펌프(3)에 의해 냉각수를 순환시켜 냉각시키고 있다.The cylinder block 1 and the cylinder head 2 are exposed to high temperature combustion heat, and in order to prevent damage due to overheating, the cooling water is circulated and cooled by the water pump 3 as shown in FIG.

실린더블록(1)과 실린더헤드(2)를 순환하면서 냉각시킨 냉각수는 온도가 상승되어 있기 때문에 라디에이터(4)를 통해 방열 냉각시킨 후 다시 워터펌프(3)에 의해 급송되어지게 된다.Since the coolant cooled while circulating the cylinder block 1 and the cylinder head 2 is elevated in temperature, the cooling water is cooled by heat radiating through the radiator 4 and then fed again by the water pump 3.

그러나 라디에이터가 누수되거나 라디에이터 캡(5)의 이상 및 냉각수의 부족등의 이상이 발생하면 워터펌프(3)의 흡입구(6)측에 부압이 형성되어 워터펌프(3)의 파손이 유발하고 엔진에 심각한 문제를 가져오게 되나 종래의 경우 이를 알 수 없기 때문에 가끔 엔진후드를 열고 냉각수의 적정량 정도를 점검하는 데 그치고 있어 워터펌프 및 엔진 손상을 일으키게 되는 문제점이 있다.However, if the radiator leaks or an abnormality such as an abnormality of the radiator cap 5 and lack of cooling water occurs, a negative pressure is formed on the inlet 6 side of the water pump 3, causing damage to the water pump 3 and causing damage to the engine. It causes a serious problem, but in the conventional case, because it is not known, sometimes only open the engine hood to check the appropriate amount of cooling water, there is a problem that causes water pump and engine damage.

이에 본 발명은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 것은 라디에이터의 누수가 라디에이터 캡의 이상 및 냉각수 부족 등에 기인하여 펌프흡입구측에 부압이 기준치 이상 형성되면 경고 등을 점등하고 차단밸브를 작동하여 워터펌프로 물이 역류하는 것을 차단하는 엔진 냉각시스템의 이상 발생 경보장치를 제공하는데 있다.Accordingly, the present invention has been proposed in view of the above problems, and its object is to cause a leak of the radiator and cause a warning valve to turn on the shutoff valve when a negative pressure is formed at the pump inlet side due to an abnormality of the radiator cap and the lack of cooling water. It is to provide an alarm system for occurrence of an abnormality in the engine cooling system that operates to block water from flowing back to the water pump.

이하 본 발명의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

제1도는 본 발명에 의한 엔진 냉각시스템의 이상 발생 경보장치를 나타내는 도면으로 종래예에서 설명한 구성과 동일한 것은 같은 부호를 사용하여 설명한다.FIG. 1 is a diagram showing an abnormality occurrence alarm device of an engine cooling system according to the present invention. The same components as those described in the prior art will be described with the same reference numerals.

도면중 부호 7은 라디에이터(4)와 워터펌프(3)를 연결하는 펌프흡입관로이며 부호 8은 펌프흡입구(6) 근방의 펌프흡입관로(7)의 도중에 접속되는 부압감지센서이다.In the figure, reference numeral 7 denotes a pump suction pipe path connecting the radiator 4 and the water pump 3, and reference numeral 8 denotes a negative pressure sensing sensor connected in the middle of the pump suction pipe path 7 near the pump suction port 6.

상기 부압감지센서(8)는 펌프흡입관로(7)에 연통하도록 설치되는 절연체인하우징(9)과 하우징(9) 내부를 다이어프램실(10)과 대기압실(11)로 구획하는 다이어프램(12) 및 다이어프램(12)이 펌프흡입관로(7)에 형성되는 부압에 의해 이동하게 될 때 회로를 온 접속하는 스위치기구(13)로 구성된다.The negative pressure sensor 8 is a diaphragm 12 which divides the inside of the housing 9 and the diaphragm chamber 10 and the atmospheric pressure chamber 11 installed in communication with the pump suction pipe line 7. And a switch mechanism 13 for connecting the circuit on when the diaphragm 12 is moved by the negative pressure formed in the pump suction pipe line 7.

상기 스위치기구(13)는 절연체 하우징(9)에 고정되는 고정접점(14)과 상기 다이오프램(12)에 고정되어 함께 이동하는 가동접점(15) 및 상기 가동접점(15)을 복귀하는 방향(off 방향)으로 잡아 당기는 리턴스프링(16)과로 구성된다.The switch mechanism 13 has a fixed contact 14 fixed to the insulator housing 9 and a movable contact 15 fixed to the diaphragm 12 to move together and a direction of returning the movable contact 15 ( off spring) and the return spring 16 is pulled out.

그리고 상기 스위치기구(13)가 온 접속되면 점등되는 경고등(17)이 운전석 계기판에 마련되어 있다.And the warning light 17 which turns on when the said switch mechanism 13 is turned on is provided in the driver's seat instrument panel.

또한 상기 부압감지 센서(8)에 의한 회로의 온 접속시 이 신호는 전자제어장치(18)에 인가되며 전자제어장치(18)는 부압에 의한 냉각수의 역류를 차단하기 위한 역류차단밸브(19)를 구동제어하여 펌프토출구측을 차단하게 된다.In addition, the signal is applied to the electronic controller 18 when the circuit is connected to the negative pressure sensor 8 by the negative pressure sensor 8, and the electronic controller 18 blocks the reverse flow of the cooling water by the negative pressure. Drive control to shut off the pump outlet.

이와같은 본 발명은 라디에이터(4)가 고장으로 누수되거나 또는 라디에이터캡(5)의 이상 및 기타 사유로 워터펌프(3)측에 유입되는 냉각수의 량이 적어지면 펌프흡입구측, 즉 펌프흡입관로(7)내에 부압 발생이 커지게 되며 이 부압에 의해 다이어프램(12)이 흡입되어 이동하게 된다.In the present invention as described above, when the radiator 4 is leaked due to a failure or the amount of the coolant flowing into the water pump 3 is reduced due to an abnormality of the radiator cap 5 and other reasons, the pump suction port side, that is, the pump suction pipe path 7 Negative pressure is generated inside the diaphragm and the diaphragm 12 is sucked and moved by this negative pressure.

이때 부압이 기준치 보다 커지면(절대값개념) 다이어프램(12)의 이동량이 커져 이에 연동하는 가동접점(15)이 고정접점(14)에 닿아서 회로를 온 접속하게 되며 이에따라 밧데리전원(20)이 공급되어 경고등(17)이 점등되며 경고등(17)이 점등되면 운전자는 즉시 냉각시스템의 점검을 수행하여 단순 냉각수 부족시에는 냉각수를 보충하고 라디에이터 및 라디에이터 캡 등의 구조적 이상일 때에는 정비점검을 받게 되는 것이다.At this time, when the negative pressure is larger than the reference value (absolute value concept), the amount of movement of the diaphragm 12 increases, and the movable contact 15 interlocking with it contacts the fixed contact 14 to turn on the circuit, thereby supplying the battery power source 20. When the warning light 17 is turned on and the warning light 17 is turned on, the driver performs an inspection of the cooling system immediately, and when a simple coolant is insufficient, it supplements the coolant and receives a maintenance inspection when there is a structural abnormality such as a radiator and a radiator cap.

한편 펌프흡입관로(7)내의 부압이 커지게 되면 냉각수가 워터펌프(3)로 역류하게 되므로 이를 방지하기 위해 부압감지센서(8)가 온 접속되는 신호를 받아 전자제어장치(18)가 역류차단밸브(19)를 회동 작동시켜 역류를 차단하여 부식등 워터펌프 손상을 방지하게 된다.On the other hand, when the negative pressure in the pump suction pipe 7 increases, the cooling water flows back to the water pump 3 so that the electronic pressure control device 18 blocks the reverse flow in response to the negative pressure sensor 8 being connected. By rotating the valve 19 to block the back flow to prevent damage to the water pump, such as corrosion.

이상과 같은 본 발명에 의하면 워터펌프에 공급되는 냉각수량이 적어지게 되면 펌프흡입관로상에 강한 부압이 형성되는 것은 이용하여 그 부압이 기준치 이상일 때 회로를 온 접속하는 스위치기구를 마련하여 경고 등을 점등시키고 동시에 역류차단밸브를 작동시켜 워터펌프로의 냉각수의 역류를 방지하므로써 냉각계 이상을 경고 등을 통해 즉시 알 수 있어 정비점검이 용이하며 워터펌프 및 엔진의 손상을 방지하여 안전사고를 미연에 방지하게 되는 효과가 있다.According to the present invention as described above, when the amount of cooling water supplied to the water pump decreases, a strong negative pressure is formed on the pump suction pipe, and when the negative pressure is higher than the reference value, a switch mechanism for connecting and connecting the circuit is provided. At the same time, the reverse flow shutoff valve is operated to prevent the reverse flow of the cooling water to the water pump, so that the abnormality of the cooling system can be immediately known through a warning, etc., so that it is easy to inspect and to prevent damage to the water pump and the engine. There is an effect to prevent.
