Description

차량의 윈도우글래스 와셔액 체크밸브 구조Window glass washer liquid check valve structure of vehicle

본 발명은 차량의 윈도우글래스 와셔액 체크밸브 구조에 관한 것으로서, 특히 와셔액의 역류를 보다 확실히 방지하며, 와셔액 공급 호스에 진공부가 발생치 않도록 한 차량의 윈도우글래스 와셔액 체크밸브 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a window glass washer liquid check valve of a vehicle, and more particularly to a structure of a window glass washer liquid check valve of a vehicle in which a backflow of the washer liquid is more reliably prevented and a vacuum part is not generated in the washer liquid supply hose.

일반적으로 차량의 윈도우글래스에는 우천시 빗물을 닦아내어 운전자의 시계를 확보하도록 하는 와이퍼(Windshield Wiper)가 설치되어 있다. 이러한 와이퍼는 작동방향에 따라 여러 종류가 있으며 전방의 윈도우글래스는 물론, 후방의 리어글래스에도 설치된 것이 있다.Generally, a windshield wiper is installed on a window glass of a vehicle to wipe rainwater in the rain so as to secure a driver's watch. There are many kinds of these wipers, depending on the direction of operation, and are installed on the rear window glass as well as the front window glass.

이러한 차량의 윈도우글래스는 항시 청결한 상태를 유지하여야만 운전자의 쾌적한 시계를 확보하여 안전운행 하도록 되는 바, 와이퍼는 우천시뿐만 아니라 평상시에도 먼지 등이 쌓여 더러워졌을 때도 사용할 수 있다.The window glass of such a vehicle must be kept clean at all times to secure a comfortable watch for the driver to operate safely, and the wiper can be used even when it is dirty in the rain as well as in the rain.

그러나 윈도우글래스에 물기가 없는 상태에서의 와이퍼 작동은 와이퍼를 구동하는 모터의 손상을 가져올 뿐만 아니라 잘 닦이지도 않고 먼지와 와이퍼블래이드와의 마찰로 인하여 윈도우글래스에 미세한 스크래치를 발생시키므로 매우 좋지 못한 것이다.However, wiper operation without the window glass is not very bad because it not only damages the motor driving the wiper, but also causes the scratch on the window glass due to the friction between the wiper blade and dirt.

따라서 차량에는 와이퍼 작동과 동시에 와셔세정액(Washer Fluid ; 이하 와셔액)을 윈도우글래스에 분사하도록 하는 장치가 되어 있는 바, 이는 도 1에 도시한 바와 같이 와셔액탱크(30)에 저장된 와셔액을 펌프(31)를 통해 호스(32)를 경유하여 차량의 외측, 즉 후드 상단이나 도면에 예시한 리어글래스 상단에 설치된 노즐(33)에서 분사하도록 되어 있다.Therefore, the vehicle is provided with a device for spraying the washer cleaning fluid (Washer Fluid; hereinafter washer fluid) to the window glass at the same time as the wiper operation, which pumps the washer fluid stored in the washer fluid tank 30 as shown in FIG. Through the hose 32 through the outside of the vehicle, that is, the top of the hood or the nozzle 33 provided on the top of the rear glass illustrated in the drawing is to be injected.

이러한 와셔액 분사구조에서 상기 와셔액탱크(30) 쪽의 호스(32) 소정부에는 체크밸브(10)가 설치되어 있는데, 이는 와셔액의 역류를 방지하고 항시 노즐(33)과 체크밸브(10)사이에 와셔액이 채워져 있도록 함으로써 운전석에서 스위치를 작동시키면 즉시 분사될 수 있게 하는 것이다.In the washer fluid injection structure, a check valve 10 is installed at a predetermined portion of the hose 32 on the side of the washer fluid tank 30, which prevents the backflow of the washer fluid and always between the nozzle 33 and the check valve 10. By ensuring that the washer fluid is filled, the switch can be sprayed immediately when the switch is operated from the driver's seat.

도 3에 종래 체크밸브(10)의 구조를 단면으로 나타내었다.3 shows the structure of a conventional check valve 10 in cross section.

도시한 바와 같이 밸브 몸체(11) 양쪽으로 호스(32)가 끼워져 있으며, 내부에는 관통된 유로(12)가 형성되어 있다. 이러한 유로(12)에는 스프링(13)이 설치되어 있고, 와셔액탱크 방향 쪽 유로 입구에는 체크볼(14)이 설치된 구조이다.As shown in the drawing, the hose 32 is fitted to both sides of the valve body 11, and a penetrating flow passage 12 is formed therein. The flow passage 12 is provided with a spring 13, and the check ball 14 is provided at the inlet of the flow path in the washer fluid tank direction.

따라서 스위치를 작동시키면 와셔액의 유압에 따라 체크볼(14)이 스프링(13)을 압축하며 유로가 열려 와셔액을 공급하고, 스위치를 오프시키면 스프링의 탄성으로 체크볼(14)이 다시 유로입구(12a)를 막아 와셔액탱크 쪽으로의 역류를 방지하게 된다.Accordingly, when the switch is operated, the check ball 14 compresses the spring 13 according to the hydraulic pressure of the washer fluid, and the flow path is opened to supply the washer fluid. When the switch is turned off, the check ball 14 returns to the flow path inlet 12a due to the elasticity of the spring. ) To prevent backflow into the washer fluid tank.

그러나 상기와 같은 종래 와셔액 체크밸브의 구조는 체크볼(14)과 유로 입구(12a)와의 접촉부에 먼지 등 기타 불순물이 끼게 되면 체크밸브의 기능이 상실되며, 호스(32) 내부에 진공부가 발생하여 운전석에서 스위치를 작동시켜도 즉시로 충분한 양의 와셔액이 분사되지 않아 와이퍼의 작동이 불안하고 자칫 와이퍼 구동모터의 손상을 초래할 수 있다는 문제점이 있었다.However, the structure of the conventional washer liquid check valve as described above loses the function of the check valve when dust or other impurities are caught in the contact between the check ball 14 and the flow path inlet 12a, and a vacuum part is generated inside the hose 32. Even if the switch is operated in the driver's seat, a sufficient amount of washer fluid is not immediately injected, which causes an unstable operation of the wiper and may cause damage to the wiper drive motor.

본 발명은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로, 본 발명의 목적은 체크밸브 유로의 개폐기능을 확실하게 수행할 수 있도록 함으로써 와셔액의 역류를 방지하며, 따라서 호스에 진공부가 발생치 않도록 하는 차량의 윈도우글래스 와셔액 체크밸브 구조를 제공하는 데 있다.The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to prevent the backflow of the washer liquid by reliably performing the opening and closing function of the check valve flow path, thereby preventing the vacuum portion from occurring in the hose. To provide a window glass washer liquid check valve structure of a vehicle.

Provide structure.

이하 첨부된 예시도면을 참조하여 본 발명의 바람직한 실시예를 보다 상세히 설명하면 다음과 같으며 종래와의 동일부는 동일부호로 표기한다.DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same parts as in the related art are denoted by the same reference numerals.

도 2는 본 발명 와셔액 체크밸브의 구성을 나타낸 단면도다.2 is a cross-sectional view showing the configuration of the washer liquid check valve of the present invention.

도시한 바와 같이 본 발명은 종래의 체크볼 대신에 보다 유로 입구(12a)를 확실히 차단할 수 있도록 모양을 형성한 패킹부재(20)를 설치한다. 이러한 패킹부재(20)는 유로입구(12a)를 차단하는 러버패킹(21)과, 밸브 몸체(11) 내부의 스프링(13)과 안정감 있게 결합되는 스프링가이드(22)와 일체로 되어있다.As shown in the present invention, instead of the conventional check ball, the packing member 20 is formed to have a shape so that the flow path inlet 12a can be reliably blocked. The packing member 20 is integrated with the rubber packing 21 for blocking the flow path inlet 12a and the spring guide 22 which is stably coupled with the spring 13 inside the valve body 11.

즉 상기 스프링가이드(22)의 일측은 러버패킹(21)과 끼움결합되어 일체로 된 것이며, 타측은 홈(22a)을 형성하여 스프링(13)이 안착되도록 구성된 것이다.That is, one side of the spring guide 22 is integrally coupled with the rubber packing 21, and the other side is configured to form the groove 22a so that the spring 13 is seated.

따라서 본 발명은 와셔액을 분사시킨 후 스위치가 오프되면 스프링(13)의 탄성 복귀로 상기 패킹부재(21)가 유로입구(12a)에 긴밀하게 밀착되므로 와셔액이 와셔액탱크쪽으로 역류되는 것을 확실히 방지하게 된다. 이에 따라 체크밸브를 중심으로 노즐쪽의 호스(32)에는 항시 와셔액이 채워져 있으므로 운전석에서 분사스위치를 작동시키면 지연시간 없이 곧바로 분사된다.Therefore, in the present invention, when the switch is turned off after spraying the washer fluid, the packing member 21 is closely adhered to the flow path inlet 12a by the elastic return of the spring 13, thereby preventing the washer fluid from flowing back toward the washer fluid tank. . Accordingly, since the washer fluid is always filled in the hose 32 on the nozzle side around the check valve, when the spray switch is operated in the driver's seat, the spray is immediately injected without delay.

이상과 같이 본 발명 차량의 윈도우글래스 와셔액 체크밸브 구조는 유로의 확실한 차단효과로 와셔액의 역류를 방지하게 되며, 노즐쪽의 호스에 진공부가 발생하지 않게 되므로 운전석에서 스위치를 작동시킬 때 즉시로 충분한 양의 와셔액이 분사되어 와이퍼의 작동이 원활하게 되고 와이퍼구동모터의 손상을 미연에 방지하는 효과도 있다.As described above, the window glass washer liquid check valve structure of the vehicle of the present invention prevents the back flow of the washer liquid due to the certain blocking effect of the flow path, and since the vacuum part is not generated in the hose of the nozzle side, a sufficient amount immediately when the switch is operated in the driver's seat. The washer fluid is sprayed to facilitate the wiper operation and to prevent damage to the wiper drive motor.
