Description

와셔액 분사노즐{Nozzle for injecting a washer fluid}Nozzle for injecting a washer fluid}

본 발명은 자동차의 와셔액 분사노즐에 관한 것으로서, 보다 상세하게는 분사노즐을 통한 와셔액의 분사시에 앞 유리창의 전체에 걸쳐서 고르게 와셔액을 분사시키는 분사노즐에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washer fluid injection nozzle of a motor vehicle, and more particularly, to an injection nozzle for spraying washer liquid evenly over the entire windshield when the washer liquid is injected through the injection nozzle.

일반적으로, 자동차에는 앞 유리창의 이물질을 제거하기 위해 엔진룸의 일측에 와셔액 분사장치가 설치된다. 이 와셔액 분사장치에 의해 와셔액을 앞 유리창에 분사시킨후 와이퍼를 작동시켜 와이퍼가 이물질을 제거하도록 되어 있다.Generally, a washer fluid injector is installed at one side of an engine room to remove foreign substances from a windshield. The washer liquid is sprayed on the windshield by the washer liquid injector, and then the wiper is operated to remove the foreign matter.

종래의 와셔액 분사장치는, 도 1에 도시된 바와 같이, 탱크(1), 펌프(2) 및 분사노즐(3)을 포함한다. 탱크(1)는 자동차의 엔진룸의 측벽에 설치되고, 내부에 와셔액이 저장된다. 펌프(2)는 탱크(1)의 하부를 통해 유입된 와셔액을 고압으로 유입호스(4)를 통해 분사노즐(3)로 전달한다. 분사노즐(3)은 펌프(2)를 통해 유입된 와셔액을 앞 유리창에 분사하게 된다. 도 1에 도시된 분사노즐(3)은 오리피스(3a) 수가 1개인 것을 도시하고 있다. 이러한 분사노즐(3)은 오리피스(3a) 수가 1개이기 때문에 앞유리창에 골고루 분사하지 못하는 단점이 있었다.The conventional washer liquid injector includes a tank 1, a pump 2, and an injection nozzle 3, as shown in FIG. The tank 1 is installed on the side wall of the engine room of the vehicle, and the washer liquid is stored therein. The pump 2 transfers the washer liquid introduced through the lower portion of the tank 1 to the injection nozzle 3 through the inlet hose 4 at high pressure. The spray nozzle 3 sprays the washer liquid introduced through the pump 2 onto the windshield. The injection nozzle 3 shown in FIG. 1 shows that the number of orifices 3a is one. This injection nozzle 3 has a disadvantage that it can not evenly spray on the windshield because the number of orifices (3a) is one.

도 1의 문제점을 해결하기 위한 대안이 대한민국 특허출원 제 1997-0080379호에 공지되어 있다. 공지된 분사노즐(3)은, 도 2에 도시된 바와 같이, 유입구(3a)와 토출구(3b) 사이에 와류실(3d)을 설치하여 와류현상을 이용하여 와셔액이 분사되게 하는 방식이다. 이는 도 1의 분사노즐(3)보다는 넓은 면적에 걸쳐 와셔액을 고르게 분사시킬 수 있다. 즉, 와류실(3d)을 두어 유속차이 및 와류현상에 의해 와셔액을 고르게 분사시킨다.An alternative for solving the problem of FIG. 1 is known from Korean Patent Application No. 1997-0080379. In the known injection nozzle 3, as shown in FIG. 2, a vortex chamber 3d is provided between the inlet port 3a and the discharge port 3b so that the washer liquid is injected using the vortex phenomenon. This can spray the washer liquid evenly over a larger area than the injection nozzle 3 of FIG. 1. That is, the vortex chamber 3d is provided so that the washer liquid is evenly sprayed by the flow rate difference and the vortex phenomenon.

그러나, 상기와 같은 종래의 와셔액 분사장치들은 다음과 같은 단점들이 있었다.However, the conventional washer liquid injectors have the following disadvantages.

즉, 도 1에 도시된 오리피스가 1개인 분사노즐의 경우에는 유리창의 일부에만 와셔액이 분사되기 때문에 오염물을 세척하는데 어려움이 있었다. 또한, 도 2의 경우에도 차체의 진동에 의한 영향으로 와셔액이 비산되는 정도가 달라질 수 있고, 분사노즐 내부에 별도의 와류실의 형성으로 인해 분사노즐의 가공이 어려운 문제점이 있었다.In other words, in the case of the injection nozzle having one orifice shown in FIG. In addition, in the case of FIG. 2, the degree to which the washer fluid is scattered may be changed due to the vibration of the vehicle body, and the processing of the injection nozzle is difficult due to the formation of a separate vortex chamber inside the injection nozzle.

본 발명은 상기와 같은 점을 감안하여 안출된 것으로, 분사노즐의 가공이 쉽고 유리창 전체에 걸쳐서 고르게 분사가 가능하여 기존 노즐에 비해 오염물 세척능력이 탁월한 분사노즐을 제공함에 그 목적이 있다.The present invention has been made in view of the above, it is an object of the present invention to provide a spray nozzle excellent in the cleaning ability of contaminants compared to the conventional nozzle because it is easy to process the spray nozzle and can be sprayed evenly throughout the glass window.

도 1은 일반적인 와셔액 분사장치를 도시한 개념도.1 is a conceptual view showing a typical washer liquid injector.

도 2는 종래의 분사노즐의 도 1의 Ⅱ-Ⅱ부분을 도시한 확대단면도.Figure 2 is an enlarged cross-sectional view showing a II-II portion of Figure 1 of a conventional injection nozzle.

도 3은 본 발명에 따른 분사노즐의 도 1의 Ⅱ-Ⅱ부분을 도시한 확대단면도.Figure 3 is an enlarged cross-sectional view showing a II-II portion of Figure 1 of the injection nozzle according to the present invention.

상기와 같은 목적을 달성하기 위해 본 발명에 따른 장치는 와셔액 유입호스와 소통되도록 일측에 유입구가 형성되고, 타측에 와셔액을 분사시키는 토출구가 형성되며, 유입구와 토출구 사이에 와셔액이 소통되도록 통로가 형성되는 본체; 및 본체의 통로와 토출구 사이에 설치되고, 통로와 소통되도록 내부를 관통하는 적어도 둘 이상의 오리피스가 형성되며, 오리피스들을 통과한 와셔액들이 토출구의 중심의 선단에서 수렴되어 서로 충돌하도록 형성되는 토출부재를 포함한다.In order to achieve the above object, the apparatus according to the present invention has an inlet formed on one side to communicate with the washer fluid inlet hose, a discharge port for spraying the washer liquid is formed on the other side, the passage is formed so that the washer fluid is communicated between the inlet and the outlet Main body; And a discharge member installed between the passage and the discharge port of the main body, and at least two orifices penetrating through the inside to communicate with the passage, and the washer fluids passing through the orifices converge at the tip of the center of the discharge port and collide with each other. do.

바람직하게는, 본체와 토출부재는 일체로 형성된다.Preferably, the main body and the discharge member are integrally formed.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 와셔액 분사노즐은, 도 2에 도시된 바와 같이, 본체(10) 및 토출부재(20)를 포함한다.The washer liquid injection nozzle according to the present invention, as shown in FIG. 2, includes a main body 10 and a discharge member 20.

본체(10)는 와셔액 유입호스(도 1 참조)와 소통되어 와셔액이 유입되도록 일측에 유입구(11)가 형성된다. 이 유입구(11)를 통해 와셔액이 저장된 탱크로부터 펌프에 의해 공급되고, 이 와셔액이 본체(10) 내부로 유입된다. 타측에는 와셔액을 유리창의 전면에 분사시키는 토출구(12)가 형성된다. 또한, 유입구(11)와토출구(12) 사이에 와셔액이 소통되도록 통로(13)가 형성된다.The main body 10 is in communication with the washer fluid inlet hose (see Fig. 1) is formed with an inlet 11 on one side so that the washer fluid is introduced. The washer fluid is supplied by the pump from the tank through which the washer fluid is stored, and this washer liquid flows into the main body 10. On the other side, a discharge port 12 for spraying the washer liquid on the front surface of the glass window is formed. In addition, the passage 13 is formed so that the washer fluid is communicated between the inlet 11 and the outlet 12.

토출부재(20)는 본체(10)의 통로(13)와 토출구(12) 사이에 설치된다. 이 토출부재(20)에는 본체(10)의 통로(13)와 소통되어 와셔액이 유리창으로 분사될 수 있도록 내부를 관통하는 적어도 둘 이상의 오리피스(21)가 형성된다. 이 오리피스들(21)은 토출구(12)의 중심선에 대해서 각각 일정한 각도를 가지고 경사져 있다.The discharge member 20 is provided between the passage 13 of the main body 10 and the discharge port 12. The discharge member 20 is formed with at least two orifices 21 communicating with the passage 13 of the main body 10 and penetrating the inside so that the washer liquid can be injected into the glass window. These orifices 21 are inclined at regular angles with respect to the center line of the discharge port 12, respectively.

바람직하게는, 본체(10)와 토출부재(20)가 일체형으로 성형될 수 있다. 즉, 별도의 토출부재(20)가 없이 와셔액이 토출되도록 본체(10)의 단부에 경사진 둘 이상의 오리피스들(21)가 형성된다.Preferably, the main body 10 and the discharge member 20 may be integrally molded. That is, two or more inclined orifices 21 are formed at the end of the main body 10 so that the washer liquid is discharged without a separate discharge member 20.

따라서, 본 발명은 서로 다른 경사로 형성된 오리피스들(21)을 통해 토출되는 각각의 와셔액들은 대부분이 본체(10)의 토출구(12)의 중심 선단에서 서로 수렴하게 된다. 이렇게 수렴된 와셔액들은 서로 충돌하게 된다. 이 충돌로 인하여 와셔액들은 미세한 액적들을 가진 액막의 형태로 변형되고, 동시에 이 액적들은 분사방향에 대해서 넓은 각도를 가지면서 유리창에 골고루 분사된다. 대부분의 와셔액들이 충돌하지만, 서로 충돌하지 못한 소량의 와셔액들은 각각의 오리피스(21)의 경사각에 따라 일정각도를 유지하면서 외부로 토출된다. 따라서, 토출된 와셔액들은 유리창의 넓은 면적에 분사되어 오염물의 세척이 훨씬 용이해진다.Accordingly, in the present invention, each of the washer liquids discharged through the orifices 21 formed at different inclinations converges with each other at the center tip of the discharge port 12 of the main body 10. These converged washers collide with each other. Due to this collision, the washer liquid is deformed into a liquid film having fine droplets, and at the same time, the droplets are evenly sprayed onto the glass window at a wide angle with respect to the spraying direction. Although most of the washer liquids collide, a small amount of the washer liquids which do not collide with each other are discharged to the outside while maintaining a constant angle according to the inclination angle of each orifice 21. Thus, the discharged washer liquid is sprayed on a large area of the glass window, making it easier to clean the contaminants.

상기된 바와 같은 본 발명에 따른 장치는, 유리창의 넓은 면적에 걸쳐서 고르게 분사되기 때문에 오염물의 세척이 훨씬 용이해지고, 별도의 와류실을 형성할 필요가 없기 때문에 구조가 간단하여 가공이 쉬운 효과가 있다.The apparatus according to the present invention as described above, because it is evenly sprayed over a large area of the glass window, it is much easier to wash the contaminants, and because there is no need to form a separate vortex chamber, the structure is simple and easy processing is effective .

이상에서는, 본 발명을 특정의 바람직한 실시예에 대해서 도시하고 설명하였다. 그러나, 본 발명은 상술한 실시예에만 한정되는 것은 아니며, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 이하의 특허청구범위에 기재된 본 발명의 기술적 사상의 요지를 벗어남이 없이 얼마든지 다양하게 변경 실시할 수 있을 것이다.In the above, the present invention has been illustrated and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiments, and those skilled in the art to which the present invention pertains may vary without departing from the spirit of the technical idea of the present invention described in the claims below. It will be possible to carry out the change.
