Abstract

A washer nozzle-equipped camera apparatus includes a camera and a washer nozzle. The washer nozzle has a window spray outlet for spraying a washer fluid, supplied from a supply unit such as a pump, on a window of a vehicle. The washer nozzle further has a window duct for carrying the washer fluid to the window spray outlet. The washer nozzle further has a camera spray outlet for spraying the washer fluid on a lens of the camera. The washer nozzle further has a camera duct for carrying the washer fluid to the camera spray outlet.

Claims

1. A washer nozzle-equipped camera apparatus comprising:

a camera having a lens; and

a washer nozzle having a window spray outlet for spraying a washer fluid, supplied from a supply unit, on a vehicle window and a window duct for carrying the washer fluid to the window spray outlet, the washer nozzle further having a camera spray outlet for spraying the washer fluid on the lens of the camera and a camera duct for carrying the washer fluid to the camera spray outlet.

2. The apparatus according to claim 1, wherein

the washer nozzle further has a washer fluid inlet for receiving the washer fluid from the supply unit,

the window duct extends from the washer fluid inlet to the window spray outlet, the window duct branching at a branch portion located on the way from the washer fluid inlet to the window spray outlet, and

the camera duct extends from the branch portion to the camera spray outlet.

3. The apparatus according to claim 2, further comprising:

a switcher located at the branch portion of the window duct to allow the washer fluid to flow from the washer fluid inlet to the camera spray outlet through the camera duct.

4. The apparatus according to claim 3, wherein

the switcher includes a spring and a valve coupled to the spring,

the valve works against a biasing force of the spring by receiving pressure of the washer fluid so that the washer fluid flows from the washer fluid inlet to the camera spray outlet through the camera duct.

the washer nozzle further has an air inlet for taking in air and an air duct extending from the air inlet to the camera duct.

8. The apparatus according to claim 1, wherein

the washer nozzle further has a recess for preventing the washer fluid from adhering to the lens of the camera, the recess being located to surround the periphery of the lens.

9. The apparatus according to claim 8, wherein

the washer nozzle further has a drain duct for draining the washer fluid in the lowest portion of the recess.

10. A washer nozzle comprising:

a window spray outlet for spraying a washer fluid, supplied from a supply unit, on a vehicle window;

a camera spray outlet for spraying the washer fluid on a lens of a camera;
