充分に満たすようにはなつていないという問題点
があつた。 However, the mechanism of the outside air intake chamber is required to (a) improve the performance of introducing outside air into the passenger compartment, (b) prevent water from entering when driving or washing the car, and (c) prevent foreign matter such as dead leaves from entering. Ru. Therefore, in the past, cowl nets with draining plates or cowl nets with a convex shape to expand the outside air intake area have been adopted in some car models. ) The problem was that it was not designed to fully meet the needs of the public.
この考案は、前記の問題点に対して、これを解
消する自動車のカウルネツト構造を提供するよう
にしたものである。
This invention provides an automobile cowl net structure that solves the above-mentioned problems.

This invention is based on an outside air intake chamber that is provided at the lower part between the front end of the windshield and the rear edge of the hood and located in the vehicle width direction from the center of the vehicle body. The standing wall of
A cowl net structure for an automobile, characterized in that the cowl net is provided in a step-like manner that gradually increases in height from the center of the vehicle body in the vehicle width direction, and is stretched over an outside air intake port above an outside air intake chamber divided by the plurality of vertical walls. It is.
この考案の詳細を、第1図〜第3図に示す実施
例について説明すると、次のとおりである。
The details of this invention will be explained below with reference to the embodiments shown in FIGS. 1 to 3.
この考案は、第1図に示すように、自動車の走
行により、フード17の上面に沿つて、前方から
侵入してくる外気Eがフロントガラス2に当たる
ようになる外気取入室25の上方においては、
Eaで示すように左右に方向を変え、車幅方向に
流れることに着目して、案出したものである。 In this invention, as shown in FIG. 1, above the outside air intake chamber 25, where outside air E enters from the front along the top surface of the hood 17 and hits the windshield 2 as the car runs,
This idea was devised by focusing on the fact that the flow changes direction left and right and flows in the width direction of the vehicle, as shown by Ea.
外気取入室25は、第2図に示すように、車幅
方向に横長に形成され(第2図は車体中心線C−
Cに対する左半分を示し、これと対称状に右半分

8,29,30を有する。そしてこれらの立壁2
8,29,30の上面に、外気取入口28a,2
9a,30aを形成し、第3図に示すように、そ
れぞれにカウルネツト32を張設する。 As shown in FIG. 2, the outside air intake chamber 25 is formed horizontally in the vehicle width direction (FIG. 2 shows the vehicle center line C-
The upper panel 27 is a stepped wall 2 that gradually becomes higher in the vehicle width direction from the center of the vehicle body.
It has 8, 29, 30. And these standing walls 2
8, 29, 30, outside air intakes 28a, 2
9a and 30a are formed, and a cowl net 32 is stretched over each as shown in FIG.
外気取入室25の下部パネル34には、立壁2
8,29,30の下方に位置しないようにして車
幅側に立形の外気導入ダクト36を固設し、その
下部に車室へ接続する連通ダクト37を形成す
る。そしてその内部にモータ38によつて駆動さ
れるブロワ39を設置する。 The lower panel 34 of the outside air intake chamber 25 has a standing wall 2.
A vertical outside air introduction duct 36 is fixedly installed on the vehicle width side so as not to be located below 8, 29, 30, and a communication duct 37 connected to the passenger compartment is formed at the lower part of the vertical outside air introduction duct 36. A blower 39 driven by a motor 38 is installed inside the blower 39 .
従つて外気Eは、Eaに方向を変えて、車幅方
向に形成した外気取入室25に沿つて流れ、一部
はじかにカウルネツト32を通つて外気取入室2
5に入るが、他部は立壁28,29,30に突き
当つて、圧力を高めてカウルネツト32を通り、
外気取入室25に入るようになる。そしてブロワ
39に促進されて車室へ送り込まれる。 Therefore, the outside air E changes its direction to Ea and flows along the outside air intake chamber 25 formed in the vehicle width direction, and a portion directly passes through the cowl net 32 and enters the outside air intake chamber 2.
5, but the other part hits the standing walls 28, 29, 30, increases the pressure and passes through the cowl net 32,
The air enters the outside air intake chamber 25. Then, it is propelled by the blower 39 and sent into the vehicle compartment.
また洗車水G等が、外気取入室25に侵入する

確実に防止することができる。 Also, car wash water G etc. may invade the outside air intake chamber 25, but as shown in FIG.
9 and 30 and then scattered in the reflection direction, and the water drain hole provided in the lower panel 34 (not shown here)
The water is then drained outside the vehicle. Since the outside air introduction duct 36 is not located below the vertical walls 28, 29, and 30, the car wash water G passes through the outside air introduction duct 36.
No intrusion into the vehicle compartment. Furthermore, standing wall 28,2
By extending the lower edges 28b, 29b, and 30b of 9 and 30 downward, it is possible to reliably prevent the car wash water G from entering the vehicle compartment.
この考案は、前記のようになつていて、自動車
の走行により進入してくる外気が、車幅方向に流

性能が著しく向上する。
This idea was developed as described above, focusing on the fact that the outside air that enters when the car is running changes its flow in the width direction of the car, and a step-shaped vertical wall is installed in the outside air intake chamber formed in this direction. , outside air is actively taken in through the cowl net on the top surface. That is, the outside air hits the vertical wall, increases its pressure, enters the outside air intake chamber through the cowl net, and is sent into the passenger compartment, so the performance of introducing outside air into the passenger compartment is significantly improved.
また外気取入室の外気導入ダクト36を、立壁
の下方に位置しないようにしてあるから、洗車水
等が斜め方向から侵入するような場合も、立壁に
当つて反射方向に飛散し、外気導入ダクトに入る
ことなく、車室への侵入が防止される。特に立壁
の下縁を下方へ長く延ばせば、侵入防止が確実に
なる。 In addition, since the outside air intake duct 36 of the outside air intake room is not located below the standing wall, even if car wash water etc. enters from an oblique direction, it will hit the standing wall and be scattered in the reflected direction, causing the outside air introduction duct to Intrusion into the vehicle compartment is prevented without entering the vehicle. In particular, if the lower edge of the standing wall is extended downward, intrusion prevention will be ensured.
なお前記のようにカウルネツトを張設してある
から、外気取入室への枯葉等の異物の侵入を防止
できることは、勿論のことである。 Since the cowl net is provided as described above, it is of course possible to prevent foreign matter such as dead leaves from entering the outside air intake chamber.
