Description

上記課題を解決するために、請求項１に記載の発明は、車両外部に搭載される車載カメラの撮影面にウォッシャ液を供給し、該撮影面に付着した異物を除去するための車載カメラ用ウォッシャノズルであって、内部に導入された前記ウォッシャ液を噴射する内部噴射孔と、吐出口及び前記吐出口と前記内部噴射孔とを連通する流路を有する吐出部とを備え、前記内部噴射孔から噴射された前記ウォッシャ液を前記吐出部内の流路に溜めつつ前記吐出口から前記車載カメラの撮影面に沿うように吐出させてその撮影面上の洗浄を行うように構成されたことをその要旨とする。 In order to solve the above-mentioned problem, the invention described in claim 1 is for an in-vehicle camera for supplying a washer liquid to an imaging surface of an in-vehicle camera mounted outside the vehicle and removing foreign matter adhering to the imaging surface. A washer nozzle, comprising: an internal injection hole for injecting the washer liquid introduced therein; and a discharge portion having a discharge port and a flow path communicating the discharge port and the internal injection hole; The washer liquid sprayed from the hole is discharged from the discharge port along the imaging surface of the in-vehicle camera while being collected in the flow path in the discharge unit, and the imaging surface is cleaned. The gist.

この発明では、内部噴射孔と、吐出口及び前記吐出口と前記内部噴射孔とを連通する流路を有する吐出部とを備えてノズルが構成され、内部噴射孔から噴射されたウォッシャ液を吐出部内の流路に溜めつつ吐出口から車載カメラの撮影面に沿うように吐出させてその撮影面上の洗浄が行われる。つまり、ウォッシャ液の吐出を撮影面に沿わせることで、ウォッシャ液の吐出部の突出形状が小さく抑えられるとともに、内部噴射孔での噴射にて流速が高められたウォッシャ液が吐出部内の流路にて車載カメラの撮影面（洗浄対象部分）の洗浄に好適な吐出形状に変換されることで、その撮影面の好適な洗浄が可能となる。
According to the present invention, the nozzle is configured to include an internal injection hole, a discharge port, and a discharge unit having a flow path that communicates the discharge port and the internal injection hole, and discharges the washer liquid injected from the internal injection hole. Cleaning is performed on the imaging surface by discharging from the ejection port along the imaging surface of the in-vehicle camera while accumulating in the flow path in the unit. In other words, by allowing the washer liquid to be discharged along the imaging surface, the protruding shape of the washer liquid discharge part can be kept small, and the flow rate within the discharge part is increased by the flow rate in the internal injection hole. By converting to a discharge shape suitable for cleaning the imaging surface (cleaning target portion) of the in-vehicle camera, the imaging surface can be cleaned appropriately.
