본 발명은 다수의 워셔액 분사노즐에 관한 것으로서, 더욱 상세하게는 윈드실드(Wind-Shield)와 근접되는 후드 후방부에 설치되는 분사노즐을 등간격으로 다수개 설치하여 윈드실드면의 세척을 보다 확실하게 하도록 하는 다수의 워셔액 분사노즐에 관한 것이다.The present invention relates to a plurality of washer fluid jet nozzles, and more particularly, to install a plurality of jet nozzles provided at the rear of the hood in close proximity to the wind-shield at equal intervals to more reliably clean the wind shield surface. To a plurality of washer fluid injection nozzles.
일반적으로, 윈드실드와 근접되는 후드 후방부에는 윈드 실드면의 세척을 이루기 위해서 분사노즐이 구비되어 있다.Generally, a spray nozzle is provided at the rear of the hood in proximity to the windshield to achieve cleaning of the windshield surface.
상기 분사노즐은 워셔탱크로 부터의 워셔액의 운전자의 버튼 조작에 의해 워셔펌프를 구동시켜 노즐을 통해 윈드실드면으로 분사시키게 하는 것으로, 종래의 분사노즐은 설치갯수가 2개로 한정되어 윈드실드면을 세척하는데 용이하지 못해 워셔액을 많이 소비시키는 결과를 낳게 하였다.The injection nozzle is to drive the washer pump by the operator's button operation of the washer fluid from the washer tank to be sprayed to the windshield surface through the nozzle, the conventional injection nozzle is limited to two installation number of the windshield surface It was not easy to wash, which resulted in a large washer wash.
따라서, 본 발명은 상기와 같은 제반 문제를 해결하기 위해 안출된 것으로서, 그 목적은 윈드 실드와 근접되는 후드 후방부에 설치되는 분사노즐을 등간격으로 다수개 설치하여 윈드실드면의 세척을 보다 확실하게 하도록 하는 다수의 워셔액 분사 노즐을 제공함에 있다.Therefore, the present invention has been made to solve the above-mentioned problems, the object is to install a plurality of injection nozzles installed at the rear of the hood close to the wind shield at equal intervals to ensure the cleaning of the windshield surface To provide a plurality of washer fluid injection nozzles.
상기 목적을 달성하기 위해 본 발명은 워셔탱크의 워셔펌프를 거쳐 분사노즐을 통해 윈드실드로 분사하게 하는 워셔액 분사장치에 있어서,In order to achieve the above object, the present invention provides a washer liquid injector for spraying the windshield through a washer pump through a washer pump.
상기 워셔탱크와 워셔펌프로 부터의 제1분출관을 양단으로 분기하여 제2분출관과 통하게 하고, 상기 제2분출관을 3단으로 분기시켜 제3분출관과 통하게하며, 상기 제3분출관을 4단으로 구성하되, 단부에 분사노즐이 구성되는 특징을 갖는다.The first ejection pipe from the washer tank and the washer pump is branched at both ends to communicate with the second ejection pipe, and the second ejection pipe is branched into three stages so as to communicate with the third ejection pipe. Consists of four stages, it is characterized in that the injection nozzle is configured at the end.
이하, 본 발명을 첨부한 도면에 의거하여 보다 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail based on attached drawing.
제1도는 본 발명에 따른 다수의 워셔액 분사노즐을 도시한 자동차의 평면도이고, 제2도는 본발명에 따른 다수의 워셔액 분사노즐액 구성을 도시한 개략도로서, 워셔탱크 (10)와 워셔펌프(12)를 거쳐 분사노즐(20)을 통해 윈드실드(22)로 분사하게 하는 워셔액 분사장치에 있어서, 상기 워셔탱크(10)와 워셔펌프(12)로 부터의 제1분출관(14)을 양단으로 분기하여 제2분출관(16)과 통하게 한다.1 is a plan view of a vehicle showing a plurality of washer fluid injection nozzles according to the present invention, and FIG. 2 is a schematic view showing a plurality of washer fluid injection nozzle liquids according to the present invention, and the washer tank 10 and the washer pump 12 are shown in FIG. In the washer liquid injector for injecting the windshield 22 through the injection nozzle 20 through the nozzle, the first jet pipe 14 from the washer tank 10 and the washer pump 12 is provided at both ends. Branching is made to communicate with the second jet pipe (16).
한편, 상기 제3분출관(18)은 4단으로 분기 구성하되, 단부에 워셔액이 분사되는 분사노즐(20)이 구비되어 있다.On the other hand, the third jet pipe 18 is divided into four stages, the end is provided with an injection nozzle 20 for spraying the washer liquid.
상기 제1분출관(14), 제2분출관(16)의 점차적인 분기는 워셔펌프(12)의 펌핑력을 제3분출관(18)의 각 분기관으로 고루 분배시키기 위함이다.The gradual branching of the first ejection pipe 14 and the second ejection pipe 16 is to distribute the pumping force of the washer pump 12 evenly to each branch pipe of the third ejection pipe 18.
한편, 상기 분사노즐(20) 중 양가장자리의 분사노즐(20)은 윈드실드(22) 전방으로 서로 소정각도로 내향되게 비스듬히 향하도록 구성된다.Meanwhile, the injection nozzles 20 at both edges of the injection nozzles 20 are configured to face the windshield 22 at an angle to be inward at an angle to each other.
상기와 같이 구성된 본 발명의 작용 및 효과를 설명한다.The operation and effects of the present invention configured as described above will be described.
워셔탱크(10)의 워셔액이 워셔펌프(12)에 의해 제1분출관(14)으로 유입되고, 유입된 워셔액은 다시 제2분출관(16), 제3분출관(18)으로 순차적 유입되면서 상기 제3분출관(18) 단부의 분사노즐(20)을 통해 같은 압력으로 윈드실드(22)에 분사되되, 양 가장자리부의 분사노즐(20)은 완전한 전방에 비해 약간 내향되는 방향으로 분사되어 와이퍼(도시않됨)와 함께 세척을 돕게 된다.The washer liquid of the washer tank 10 is introduced into the first jet pipe 14 by the washer pump 12, and the introduced washer fluid is sequentially introduced into the second jet pipe 16 and the third jet pipe 18 again. The spray nozzle 20 is sprayed to the windshield 22 at the same pressure through the spray nozzle 20 at the end of the third ejection pipe 18. The spray nozzles 20 at both edges are sprayed in a slightly inward direction compared to the front of the wiper. (Not shown) to help with cleaning.
따라서, 이와같은 본 발명을 실차에 적용하게 되면, 윈드실드로의 분사범위가 종래보다 넓어지게 되어 세척이 보다 확실하게 이루어지게 될 뿐 아니라 상대적으로 워셔액의 소비가 줄게 되는 효과가 발생된다.Therefore, when the present invention is applied to the actual vehicle, the spraying range to the windshield is wider than the conventional one, so that the washing is more surely performed and the consumption of the washer liquid is relatively reduced.
또한, 본원 발명의 제1, 제2 및 제3분출관의 단계별 분기를 통해 워셔액이 윈드실드에 고루 분배되는데, 이는 다음과 같은 유체 연속방정식을 기초로하고 있다.In addition, the washer fluid is distributed evenly to the windshield through the stepwise branching of the first, second and third ejection tubes of the present invention, which is based on the following fluid continuous equation:
일반적인 유체역학에 있어서, 유체 연속방정식은 단위 시간당 단면적을 통과하는 유속의 양에 대한 상관관계를 나타내고 있는데, 이 유체 연속방정식에 의하면 단위 시간당 튜브의 단면적을 통과하난 유속의 양은 동일하게 된다(유체의 연속방정식은 유속양의 보존법칙이라고도 한다). 이를 수학적 기호로 나타내면 다음과 같다.In general hydrodynamics, the fluid continuous equations correlate to the amount of flow rate through the cross-sectional area per unit time, which is equivalent to the amount of flow rate through the cross-sectional area of the tube per unit time. The continuous equation is also known as the law of conservation of flow rates). This is represented by mathematical symbols as follows.
pav = 일정.pav = schedule.
상기 수식에 있어서, p 는 유체의 밀도, a 는 튜브의 단면적, 그리고 v는 유체의 속도를 의미한다.In the above formula, p is the density of the fluid, a is the cross-sectional area of the tube, and v is the velocity of the fluid.
이에 따라, 유체의 밀도가 동일하면, 임의의 두 지점이 튜브내에서 유속(유량의 선속 또는 MASS FLUX)은Thus, if the density of the fluid is the same, the flow rate (flow velocity or mass flux) in any two points
A1v1- A2v2가 된다.A 1 v 1 -A 2 v 2 .
따라서, 튜브의 단면적과 유체의 속도는 역비례 관계를 갖게 되는데. 예를 들면 단면적이 크면 상대적으로 유체의 속도가 감소하게 되고, 단면적이 작으면 상대적으로 유체의 속도가 증가하게 되어, 단위 시간당 튜브의 단면적을 통과하는 유속의 양은 동일하게 된다.Therefore, the cross-sectional area of the tube and the velocity of the fluid are inversely related. For example, if the cross-sectional area is large, the velocity of the fluid is relatively low, and if the cross-sectional area is small, the velocity of the fluid is relatively increased, so that the amount of flow rate through the cross-sectional area of the tube per unit time is the same.
이와 같은 유체의 연속 방정식에 의해 본 발명의 제1, 제2 및 제3 분출관을 통해 유동(또는 분출)되는 유속(즉,워셔액)의 양은 동일하게 되며, 최종적으로 워셔액은 노즐을 통해 윈드실드로 고르게 분출하게 된다.Such a continuous equation of the fluid makes the amount of flow rate (i.e. washer fluid) flowing (or jetted) through the first, second and third jetting tubes of the present invention equal, and finally the washer fluid is windshielded through the nozzle Evenly ejected.
