BACKGROUND OF THE INVENTION
The present invention relates to an outside air intake structure for leading an outside air toward a blower motor.
DESCRIPTION OF THE PRIOR ART
Japanese Patent Unexamined Publication No. 6-278655 describes an outside air intake structure.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an outside air intake structure which is capable of surely separating outside air from water, thus leading only the outside air toward a blower motor.
According to the present invention, there is provided an outside air intake structure of an automobile. This automobile has a hood and a windshield. The outside air intake structure includes (a) a cowl panel disposed between the hood and the windshield of the automobile, the cowl panel having a cowl panel opening for taking an outside air into the automobile; (b) a dash panel having a dash panel opening such that the outside air is allowed to pass through the cowl panel opening and then the dash panel opening; and (c) a duct disposed on the dash panel to surround the dash panel opening thereby such that the outside air is allowed to pass through the cowl panel opening, then the duct, and then the dash panel opening.
According to a first aspect of the present invention, the duct has a duct opening at an end thereof for taking the outside air into the duct. This duct extends in a forward direction of the automobile such that the duct opening is disposed in a more forward position than the cowl panel opening in a fore-and-aft direction of the automobile.
According to a second aspect of the present invention, the duct has a duct opening at an end thereof for taking the outside air into the duct. The outside air intake structure further has a bulkhead extending in a substantially vertical direction in an area defined between the duct opening and the cowl panel opening.
According to a third aspect of the present invention, the cowl panel further has a raised portion. The duct has a top wall extending upwardly from a peripheral portion of the dash panel opening. The top wall extends along and adjacently below the cowl panel and has a raised portion disposed adjacently below the raised portion of the cowl panel.
