Description
일반적인 윈드쉴드 와셔 장치부는 도 1과 같이 액상의 액을 수용하는 와셔액 리저버(1), 이 리저버(1)측 액을 펌핑하는 와셔펌프(2), 펌핑된 액을 소정의 경로로 이송 시키는 호스(3), 이 호스(3)에 연결되어 와셔액을 토출 시키는 와셔노즐(4) 등으로 이루어진다.A general windshield washer device portion washer liquid reservoir (1) for receiving a liquid liquid as shown in FIG. 3) and a washer nozzle 4 connected to the hose 3 to discharge washer fluid.
이들중 와셔노즐(4)은 도 2와 같이 와셔호스(3)의 종단부에 끼워지는 연결부(5)가 있고, 후드스킨(6)에 조인트 되는 노즐부(7)로 구성되며, 노즐부(7)에는 와셔액 토출구(8)를 형성하여 이 구멍을 통해 와셔액을 토출 시킨다.Among them, the washer nozzle 4 has a connecting part 5 fitted to the end of the washer hose 3 as shown in FIG. 2, and is composed of a nozzle part 7 jointed to the hood skin 6. 7) a washer liquid discharge port 8 is formed to discharge washer liquid through this hole.
와셔액의 토출압력은 와셔펌프(2)의 펌핑력으로 정해지는데, 압력이 지나치게 클 경우 와셔액의 분사대상 영역인 윈드쉴드 글래스(9)를 초과하여 차의 루프(ROOF)나 그 뒤까지 분사될 수 있고, 반대로 압력이 낮으면 분사대상 지역에 충분히 와셔액을 보내지 못하게 된다.The discharge pressure of the washer fluid is determined by the pumping force of the washer pump 2. If the pressure is too large, the washer fluid may be injected beyond the windshield glass 9, which is the injection target area of the washer fluid, to the car's loop (ROOF) or the like. On the contrary, if the pressure is low, the washer fluid may not be sufficiently sent to the injection target area.
토출압력은 대개 이러한 액상의 와셔액의 비산 범위를 고려하여 결정되지만 공급대상 영역에 충분히 와셔액을 보낼 수 있도록 와셔액을 보내는 압력을 높게 맞춘다.와셔액의 분사영역을 윈드쉴드 글래스(9)로 하고 그것에 맞게 와셔노즐(4)의 위치 및 구조를 갖추게 되지만 도 2와 같은 와셔노즐(4)의 구조는 와셔액의 토출구(8) 형태가 직관 형태로 와셔액을 토출 시키게끔 되어있어 와셔액의 분사범위가 윈드쉴드 글래스(9)의 전면적에 고르게 확산되지 못하는 단점이 있다.The discharge pressure is usually determined in consideration of the scattering range of the liquid washer liquid, but the pressure for sending the washer liquid is set to be high so that the washer liquid can be sufficiently delivered to the area to be supplied. The position and structure of the nozzle 4 are provided, but the structure of the washer nozzle 4 as shown in FIG. 2 is such that the discharge port 8 of the washer liquid discharges the washer liquid in the form of a straight tube. There is a disadvantage that it cannot be spread evenly over the entire surface of 9).
또한 적정 토출압력 조건에서도 와셔액이 윈드쉴드 글래스(9)의 상부쪽을 초과하여 루프측에 분사되어 차의 청결 상태를 훼손 시키고 와셔액이 낭비되는 문제점이 있다.In addition, even under the proper discharge pressure conditions, the washer liquid is injected to the roof side beyond the upper side of the windshield glass 9, thereby impairing the cleanliness of the car and wasting liquid.
본 고안은 와셔액의 분사영역을 확장 시키고 또 분사영역을 벗어나지 못하도록 하는 와셔액 분사 노즐을 제공하는 것이다.The present invention is to provide a washer liquid injection nozzle that expands the injection region of the washer liquid and does not leave the injection region.

액상의 액을 수용하는 와셔액 리저버(1), 이 리저버(1)측 액을 펌핑하는 와셔펌프(2), 펌핑된 액을 소정의 경로로 이송 시키는 호스(3), 이 호스(3)에 연결되어 와셔액을 토출 시키는 와셔노즐(4) 등으로 이루어지는 인드쉴드 와셔 장치부의 직관의 분사노즐 구조에 있어서, 본 고안은 도 3과 같이 직관의 와셔액 분사노즐(4a)의 와셔액 분출 경로에 스로틀부(10)를 형성하고, 출구쪽 선단부는 상기 스로틀부(10)에서 분출 면적이 확장되는 확장토출구(11)을 형성한 것을 특징으로 한다.Washer liquid reservoir (1) for receiving liquid liquid, washer pump (2) for pumping liquid on the reservoir (1) side, hose (3) for transferring the pumped liquid to a predetermined path, and connection to the hose (3) In the structure of the injection nozzle of the straight pipe of the shielded washer device, which is made of a washer nozzle 4 for discharging the washer liquid, the present invention provides a throttle portion 10 in the washer liquid jet path of the washer liquid jet nozzle 4a of the straight pipe as shown in FIG. ) And the outlet end portion is formed with an expansion discharge port 11 in which the ejection area is expanded in the throttle portion 10.
스로틀부(10)가 형성된 본 고안의 와셔액 와셔노즐(4a)의 토출구 구조는 와셔액이 국부적으로 면적이 작은 유로를 통과하는 과정에서 와셔액의 송출 압력을 떨어뜨려 그 이후 면적이 커진 확장토출구(11)의 선단 확장면을 통해 와셔액의 분사 범위를 확장 시키게 된다.The discharge port structure of the washer fluid washer nozzle 4a according to the present invention in which the throttle part 10 is formed is reduced in the discharge pressure of the washer fluid during the passage of the washer fluid through the small area. The dispensing range of the washer fluid is extended through the distal end surface of.
도 4는 스로틀부를 통한 와셔액의 분사영역 R을 나타낸다.4 shows the injection region R of the washer liquid through the throttle portion.
분사상태는 와셔액 토출구에 스로틀부(10)가 형성되어 토출압력차가 생기고 와셔액은 확장토출구(11)를 지날 때 낮아진 압력으로 골고루 펴지게 됨으로서 분사영역이 확장되고, 토출압력 저하에 따라 직관형의 분사노즐에 조성되는 토출압력과 같거나 높은 조건에서도 분사액이 루프나 뒤쪽 유리까지 분사되는 과분사가 방지된다.In the spraying state, the throttle part 10 is formed in the washer liquid discharge port, so that the discharge pressure difference is generated, and the washer liquid is spread evenly with the lowered pressure when passing the expansion discharge port 11, thereby expanding the injection area, Even under conditions equal to or higher than the discharge pressure formed in the nozzle, the overspray of the injection liquid to the roof or the rear glass is prevented.
본 고안은 와셔액 분사 노즐의 관로에 형성된 스로틀부를 통해 윈드쉴드 글래스 분사 영역에 고른 분포로 와셔액을 분사시키고, 분사영역을 벗어나는 와셔액의 과분사 현상을 없애 차의 오손 및 와셔액의 낭비를 줄인다.The present invention sprays the washer liquid in an even distribution in the windshield glass spraying region through the throttle portion formed in the conduit of the washer liquid spraying nozzle, and reduces the waste of washer and washer fluid by eliminating the overspraying of the washer liquid out of the spraying region.
본 고안은 자동차의 와셔액 분사노즐 구조를 변경하여 와셔액의 확산영역을 넓게하고 와셔액의 분사상태를 안정시켜 주는 것이다.The present invention is to change the washer fluid injection nozzle structure of the vehicle to widen the diffusion region of the washer fluid and to stabilize the spraying state of the washer fluid.
