本考案は車両用エアダクト構造、特に車両のリアフェン
ダ部やサイドパネル部から車室内空気を車外に流出させ
る一方、車外から浸入した水が奥にまで入り込まない様
に改良した車両用エアダクト構造に関するものである。[Detailed description of the invention] This invention has been improved to allow air inside the vehicle to flow out of the vehicle from the vehicle air duct structure, especially from the rear fender and side panels of the vehicle, while preventing water from entering from outside the vehicle from penetrating deep inside the vehicle. This invention relates to a vehicle air duct structure.

があるが、このような換気装置に用いるダクトとしては
例えば第2図に示すようなものがある(実開昭51−3
886に公報参照)。Taking advantage of the fact that negative pressure areas are created at various locations on the outside of the vehicle, including a portion of the rear pillar, while the vehicle is running,
As shown in Fig. 1, a ventilation grille 2 is attached to the outer panel of the vehicle body 1 such as the rear fender, and an air duct is installed inside the ventilation grille 2 to communicate the interior and exterior of the vehicle to ventilate the interior of the vehicle. However, examples of ducts used in such ventilation systems include the one shown in Figure 2 (Utility Model No. 51-3
886).
これは、流入ロア及び流入ロアの下流側に位置する流出
口8を有し、車体外板5にシール材6を介して密封取付
けしたダクト本体3と、ダクト本体3内の空気通路内の
流出口8近くに配置した板状のバルブ部材9とから成る
。This has an inlet lower and an outlet 8 located downstream of the inlet lower, and a duct main body 3 which is hermetically attached to the outer panel 5 of the vehicle body via a sealing material 6, and an air flow inside the air passage in the duct main body 3. It consists of a plate-shaped valve member 9 placed near the outlet 8.
ダクト本体3の空気通路4は、車室上部から空気を取入
れ、車室側方部分から空気を流出させるため、上方位置
において流入ロアに連通し、下方位置において流出口8
に連通ずる略り字状の構造を有する。The air passage 4 of the duct body 3 is in communication with the inflow lower at the upper position, and the outlet 8 at the lower position in order to take in air from the upper part of the vehicle compartment and let air flow out from the side part of the vehicle compartment.
It has an abbreviated structure that communicates with the .
そしてバルブ部材9はこの空気通路4をせき止めるよう
な形に配置する一方、当該バルブ部材9には通路方向と
同じ方向に向けて通気孔10が形成してあり、この通気
孔10には、空気が流入ロア側から流出口8側へと流れ
る場合にのみ開作動する一方向バルブ11が設置しであ
る。The valve member 9 is arranged in such a manner as to block the air passage 4, while a vent hole 10 is formed in the valve member 9 in the same direction as the passage direction. A one-way valve 11 is installed that opens only when the water flows from the inflow lower side to the outflow port 8 side.
また流出口8よりも更に車体1外側には、当該流出口8
が車外に露出するのを防ぐためスリット12を形成した
ベンチレーショングリル2を取付け、外観品質の向上と
エアダクトの保護とを図っている。Furthermore, the outlet 8 is located further outside the vehicle body 1 than the outlet 8.
A ventilation grille 2 with slits 12 is installed to prevent the air from being exposed to the outside of the vehicle, thereby improving the appearance quality and protecting the air duct.
このため車室内空気は流入ロアから空気流れSとなって
空気通路4内へと流入し、一方向バルブ11の開作動と
共に通気孔10を通って流出口8へ流れ、スリット12
を通って車外へと流出する。Therefore, the air inside the vehicle becomes an air flow S from the inflow lower part and flows into the air passage 4, and when the one-way valve 11 is opened, it flows through the vent hole 10 to the outflow port 8, and flows through the slit 12.
It flows out of the vehicle through the
一方、車外から車室内へ、ダクトを通って流入しようと
する空気流れTがある時は、一方向バルブ11が通気孔
10を閉鎖し、空気の逆流現象を防止する。On the other hand, when there is an air flow T flowing from outside the vehicle into the interior of the vehicle through the duct, the one-way valve 11 closes the vent 10 to prevent backflow of air.
しかしながら、このような従来のエアダクト構造にあっ
ては、板状のバルブ部材9をダクト本体3の低位置部分
において設置し空気通路4方向に向けて所定数の通気孔
10を形成しであるため、ダクト本体3の底壁かられず
か上方に一方向バルブ及び通気孔10の下縁が位置する
ことになり、この部分に車外から侵入した塵芥や水が溜
り易くなるという不具合があった。However, in such a conventional air duct structure, the plate-shaped valve member 9 is installed at a lower position of the duct body 3, and a predetermined number of ventilation holes 10 are formed in the direction of the air passage 4. Since the lower edge of the one-way valve and the vent hole 10 is located just above the bottom wall of the duct body 3, there is a problem in that dirt and water that have entered from outside the vehicle tend to accumulate in this area.
このように、一方向バルブ11の下部に塵芥が溜ると、
当該一方向バルブ11の逆止機能が損なわれ、時にはこ
の塵芥や水が通気孔10を通って第2図中矢印T□で示
すように空気通路の内奥へと侵入し、さらには車室内へ
と逆流する恐れが生じていた。In this way, when dust accumulates at the bottom of the one-way valve 11,
The check function of the one-way valve 11 is impaired, and sometimes this dust and water can pass through the ventilation hole 10 and invade deep into the air passage as shown by arrow T□ in Figure 2, and even enter the passenger compartment. There was a risk that the flow would flow back.
また、バルブ部材9の設置状態が上記の通りであるから
、空気通路4の開口面積がバルブ部材9の設置場所で狭
くなってしまい、ダクトを流れる空気の流量を損失させ
るという問題があった。Further, since the valve member 9 is installed as described above, there is a problem in that the opening area of the air passage 4 becomes narrow at the location where the valve member 9 is installed, resulting in loss of the flow rate of air flowing through the duct.

ればならない等の問題があった。In addition, in the air duct that takes in cabin air from the rear parcel shelf and exhausts air from the rear fender, the duct body 3 may protrude into the trunk, and luggage in the trunk may hit the duct body 3. In this case, there is a possibility that the valve member 9 is deformed together with the duct body 3, so there are problems such as the need to increase the plate thickness of the duct body 3 or to particularly strengthen the fixation of the outlet portion.

。The present invention was developed by focusing on these conventional problems, and its purpose is to provide a step-like cross-sectional structure in the air passageway extending vertically, above the outlet of the duct body. By attaching a valve member, forming a vent hole in the vertical wall of the valve member in a direction crossing the air passage, and covering this vent hole with a one-way valve so that it can be opened and closed, the inside of the air passage from outside the vehicle can be removed. Even if dust or water enters the vehicle, the above problems are solved by minimizing the intrusion and preventing it from flowing back into the passenger compartment, and by ensuring a sufficient total opening area provided by the ventilation holes. be.
