Description

Vehicle Spray Washer Nozzle with Adjustable Angle {Car Spray Washer Nozzle with Adjustable Angle}

The present invention relates to a spray washer nozzle for a vehicle that is applied to a vehicle and sprays washer fluid on the windshield of the vehicle to remove foreign substances on the windshield. By maximizing the kinetic energy by forming the pressure energy into a zero state (zero state) for the injection and discharge space during the injection and supply through the injection, the collision pressure with the windshield according to the injection of the fluid is improved to increase the removal efficiency of foreign substances. Of course, it relates to a spray washer nozzle for a vehicle capable of adjusting the angle of injection of a fluid and applying it appropriately according to the shape and size of the windshield, thereby improving the quality of use.

In general, a 'windshield' is installed in a vehicle to block a wind blowing while driving or to secure a front view.

Since the surface of the windshield is frequently contaminated with 'foreign substances' such as dust, it is necessary to remove foreign substances such as dust from the surface in order to secure a sufficient front view and promote safe driving.

Accordingly, the vehicle is provided with a washer nozzle for spraying a washer fluid together with a wiper system in order to remove foreign substances adhered to the windshield.

That is, when the driver operates the washer switch installed in the driver's seat to clear the view, the washer motor connected to the washer switch operates, and the washer liquid stored in the washer liquid storage tank is transferred through the washer nozzle by the operation of the washer motor. It is sprayed on the windshield, and foreign substances that interfere with operation are removed through the sprayed washer fluid and wiper operation.

On the other hand, washer nozzles suitable for vehicles typically require the ability to clean a large area with a small amount of cleaning solution in a short time. the current situation.

As one of such 'spray-type washer nozzles', there is Korean Patent Application No. 10-2007-0114111 (name: injection nozzle/2007.11.09.), and as is known in the publication, it is installed on the upper surface of the car hood In the injection nozzle having a cross section formed with an inlet through which the washer fluid transferred through the transfer pipe flows into the flow path, and a side flow path that branches from both sides of the inlet and converges into the flow path, the inlet and the connecting portion inside the flow path An injection nozzle composed of a narrow passage having a cross section that is narrower than that of the inlet portion is described.

However, such a spray nozzle has a problem in that it is difficult to apply to a medium-to-large vehicle model because the spraying area of the washer liquid is narrow, so a spray-type washer nozzle has been proposed.

On the other hand, in the conventional spray-type washer nozzle, the method in which the center flow returns through the feedback flow path and induces the flow of the center flow that subsides the inlet part is formed so that the spray angle is very narrow, about 40 to 45°; The method in which two flows entering through a narrow space collide with each other and form three stagnant flows to form a flow out of the outlet by the flow of the stagnant flow is applied to mid-to-large-sized vehicles because the injection angle is not sufficient at 60-70°. There was a problem that was difficult to do.

Accordingly, recently, a new type of spray washer nozzle has been proposed that allows the washer liquid sprayed from the outlet to spread with a wide spray angle using the flow between the center flow and the static flow, one of which is a Korean patent application There is No. 10-2013-0156179 (Name: Vehicle Spray Washer Nozzle/2013.12.16.), and as is known in the Gazette, an inlet for the inflow of the washer fluid, an internal flow path, and a washer fluid for spraying It includes an outlet and a narrow passage formed in front of the inlet in the flow path. In particular, two stagnant flow forming spaces are formed on both sides of the inner edge of the channel, and the two front and rear stagnant flow forming spaces are formed in the flow path. A washer nozzle having a structure partitioned by boundary walls on both sides protruding toward the center of the width is described.

However, such a conventional washer nozzle does not maximize the kinetic energy in the injection space of the fluid (washer liquid), so there is a problem in that the removal efficiency of foreign substances from the windshield according to the injection of the fluid cannot be increased.

In addition, there was a problem in that the quality of use could not be improved because the injection angle of the fluid could not be adjusted, so that it could not be applied appropriately depending on the shape and size of the windshield.

Korean Patent Application No. 10-2007-0114111 (2007.11.09.)) Korean Patent Application No. 10-2013-0156179 (2013.12.16.)
