Description

[0001] Washer apparatus for vehicle [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for inspecting a washer liquid injection nozzle of a vehicle and a method for inspecting an accurate injection spot without using a liquid state component such as a washer liquid, The present invention relates to an apparatus and method for inspecting whether or not an abnormality (poor state) of a washer liquid spraying nozzle is inspected by using compressed air that does not require a work or the like.

As is well known, a pair of left and right washer fluid spray nozzles for windscreen washing are generally installed in front of the windshield of the vehicle. In this way, the washer liquid spray nozzle is installed in front of the windshield of the vehicle to spray the washer liquid onto the windshield, and at the same time, the windshield brush is operated to perform the windshield wash.

Meanwhile, it is preferable that the washer liquid injection nozzle for washing the front glass of the vehicle is set to an optimal state suitable for glass washing according to the applied vehicle. The optimum setting state of the washer fluid spray nozzle refers to a phenomenon in which the injection nozzle is clogged as well as the accurate spraying spot of the washer fluid. More specifically, the optimum setting state is a distance between the washer fluid spray nozzles from the front glass, The injection angle of each washer fluid injection nozzle, the injection amount of each washer fluid injection nozzle, and the like, are maintained in a state suitable for washing the windshield of the applied vehicle.

If any of the washer fluid injection nozzle settings are unsuitable as described above, the degree of washing of the windshield of the vehicle is less than expected. That is, when the washer liquid spray nozzle is installed too close or far from the front glass, the washer liquid spray nozzle is biased to a part of the glass to be cleaned, so that the glass washing is not uniformly performed as a whole. Further, even if the spray angle of the washer liquid spray nozzle is excessively low or high, since the washer liquid injection point is biased to a part of the glass to be cleaned, the glass washing is not uniformly performed as a whole. If the spray amount of the washer liquid sprayed through the washer liquid spray nozzle is insufficient or excessive, there is a problem that the washer liquid sprayed is insufficient and the washing is not properly performed, or a large amount flows down after washing, do.

In order to solve the problems associated with setting the washer fluid injection nozzle like this, before the washer fluid injection nozzle is applied to the actual vehicle, it is checked whether or not the washer fluid injection nozzle has an abnormality, and the setting of the washer fluid injection nozzle in the optimum state is performed .

However, at present, there is no dedicated means or device for inspecting the washing state of the windshield by the setting of the washer fluid spraying nozzle, and only basic tests such as checking whether the washer fluid is sprayed through the washer fluid spraying nozzle are performed, Is not optimal in accordance with the vehicle. For this reason, there is a disadvantage that the degree of washing of the windshield of the vehicle through the washer fluid spray nozzle is less than the expected value.

On the other hand, as disclosed in the following prior art documents, Korean Registered Patent Publication No. 10-0831020 discloses that the washer fluid injection state by the washer fluid injection nozzle can be tested under various conditions according to the applied vehicle, There has been disclosed a production inspection apparatus for an automobile washer liquid injection nozzle which can grasp the setting state.

It is apparent that the invention disclosed in this prior application is useful in various aspects in designing the washer liquid injection nozzle in various ways and inspecting the degree of glass washing according to each setting state so that an ideal washer liquid injection nozzle setting can be performed.

However, in the present invention, the washer fluid collection box must use a liquid washer fluid in order to inspect the washer fluid injection nozzle and make it possible to collect the washer fluid sprayed from the washer fluid spray nozzle, and a washer fluid collection container A washer liquid reservoir for storing an extra washer liquid and supplying the washer fluid stored in the pump to the injection nozzle, and an inspection apparatus for separately configuring an expensive vision camera for confirming a setting state such as an injection amount and a spray angle of the injection nozzle .

As described above, the present invention is disadvantageous in that the manufacturing cost is increased by installing the washer liquid collection box, the washer liquid storage box and the expensive vision camera, which are separate components, and only the expert can inspect the defective state of the washer liquid injection nozzle. In addition, in the present invention, the front glass must be installed in front of the washer fluid injection nozzle in order to inspect the setting state of the washer fluid injection nozzle, and then the defective state of the injection nozzle must be inspected and the front glass must be always removed after inspection.

In particular, since the present invention uses a washer liquid in a liquid state to inspect the state of the washer fluid spray nozzle, the water (washer fluid) that is always present on the inside / outside of the spray nozzle must be removed after inspection of the spray nozzle Further, there is a problem that the residual water remains in the inside of the injection nozzle.
