Description

  The present invention relates to a cowl structure for a vehicle, and more particularly to a cowl structure for a vehicle in which air is taken into a cowl box via an air inlet provided in a cowl top garnish.

  Conventionally, various vehicle cowl structures have been proposed in which air is introduced into a cowl box through an air inlet provided in the cowl top garnish and guided into the vehicle interior. As an example of such a prior art, there exists a technique of patent document 1, for example. Patent Document 1 discloses a cowl structure in which a bulging portion having an air discharge hole is provided at both ends of a front cowl. In this cowl structure, the running wind is introduced into the cowl box from the air inlet provided inside the bulging portion, and then the engine air is taken out from the air exhaust hole by taking away the hot air in the engine room. Heat is prevented from entering the driver's seat from inside the room, and the heat inside the engine room can be discharged efficiently. Here, the cowl box is a space formed by a dash panel, a cowl top panel, a cowl front panel, a cowl top garnish, and a cowl side panel.

However, the conventional vehicle cowl structure has the following problems.
That is, in the conventional vehicle, soil, dust, dead leaves, etc. (hereinafter referred to as soil) rolled up by one's own vehicle or another person's vehicle while traveling through the air inlet of the cowl top garnish, Was deposited inside. For this reason, when rain falls or the car is washed while dirt is accumulated inside the cowl box, water enters the cowl box through the air inlet of the cowl top garnish and enters the cowl box. Infiltrated the accumulated soil. Usually, the place where the soil or the like inside the cowl box accumulates is the bottom part inside the cowl box which is far from the air inlet of the cowl top garnish. For this reason, in general, the gentle running wind introduced from the air inlet provided in the cowl top garnish prevents the accumulation of soil, etc., or completely dries the soil retaining moisture inside the cowl box. Was difficult. Therefore, when rainwater or the like enters the cowl box, there is no choice but to wait for the water to evaporate naturally. As a result, there is a problem that moisture is held in the cowl box for a long time.

Further, in the conventional cowl structure, in order to prevent heat from entering the driver's seat from the engine room, the wind is introduced into the cowl box from the air inlet of the cowl top garnish. The heat inside the cowl box is efficiently discharged outside. However, since the wind introduced from the air inlet has a gentle flow and an insufficient amount of air, there is a limit to the amount of heat that can be exhausted, and heat from the engine may be generated inside the cowl box. Therefore, when moisture is retained in the soil accumulated in the cowl box, if the heat from the engine burns in the cowl box, a bad odor may be generated. This bad odor has flowed into the vehicle interior through the opening (outside air inlet) of the dash panel together with the humid air in the cowl box, and has become a factor in causing a strange odor to drift in the vehicle interior.
In addition, when the parts forming the cowl box are iron plates, etc., if moisture is retained in the soil inside the cowl box, the iron plates are exposed to moisture, water, and heat coming from the engine room for a long time. Since it was exposed, the malfunction which corroded this iron plate arose.
Furthermore, as described above, if dirt or the like is accumulated in the cowl box for a long period of time, the weight of the vehicle may be slightly increased, resulting in a decrease in fuel consumption. There is a fear.
In the technique described in Patent Document 1, the cowl box has its original role, that is, fresh outside air is taken into the vehicle interior from an opening (outside air introduction port) inside the cowl box, or rainwater enters the air cleaner or the vehicle interior. It does not take into account the soil that accumulates inside the cowl box, and water that has entered due to rain or car wash accumulates in the cowl box. If it is held by soil, etc., the problem that corrosion such as rust occurs in the cowl box cannot be solved.

  The present invention has been made in view of the above circumstances, and the object thereof is to suppress the accumulation of soil and the like inside the cowl box, and also the generation of a strange odor or corrosion inside the cowl box.
