【考案の詳細な説明】
本考案は自動車の換気装置に関し、その目的は走行中に
車室内の換気を効果的に行うようにしたことである。[Detailed Description of the Invention] The present invention relates to a ventilation system for an automobile, and its purpose is to effectively ventilate the interior of a vehicle while the vehicle is running.
自動車室内の自然換気装置は一般にリヤウィンド近傍の
クォータピラあるいはクォータパネル部分に吹出口が設
けられている。Natural ventilation systems for automobile interiors generally have an air outlet provided in a quarter pillar or quarter panel near the rear window.
上記従来の換気装置においても室内の換気作用は適当に
得られるが、本考案は車両の走行により発生する車体に
沿って流れる気流の負圧を利用して積極的に誘引し、室
内換気を効果的に行うよう改善したものである。Although the above-mentioned conventional ventilation system can adequately ventilate the room, the present invention utilizes the negative pressure of the airflow flowing along the car body generated by the running of the vehicle to actively induce the air to effectively ventilate the room. This has been improved to make it more accurate.
すなわち、フロントピラの部分は走行時の気流によって
大きな負圧が発生する部分である。In other words, the front pillar is a part where large negative pressure is generated due to airflow during driving.
本考案はフロントピラに対接するドアウィンドの下側の
三角隅部に吹出口を設けたことを特長とするものである
。The present invention is characterized in that an air outlet is provided at the lower triangular corner of the door window that faces the front pillar.
以下本考案の実施例を図面により説明する。Embodiments of the present invention will be described below with reference to the drawings.
第１図において１は車体、２はドア、３はウィンドガラ
ス、６はドアサツシ、１０はフロントピラである。In FIG. 1, 1 is a vehicle body, 2 is a door, 3 is a windshield, 6 is a door sash, and 10 is a front pillar.
本考案は上記の構成において、フロントピラと対接する
ドアウィンドの下側の三角隅部に第２図及び第３図に示
すようにガラスランを有する仕切部材（チャンネル）７
を設けて三角形の空間部を形成し、これを吹出口５とす
る。In the above structure, the present invention has a partition member (channel) 7 having a glass run at the lower triangular corner of the door window facing the front pillar as shown in FIGS. 2 and 3.
is provided to form a triangular space, which is defined as the air outlet 5.
この吹出口５は室内側にウレタンフオーム等の吸音板９
を、また室外側にはルーバ８をドアサツシ６と仕切部材
７とに取付け、吸音材９とルーバ８との間にドアインナ
パネルとアウタパネルとの空間に連通ずる空隙を形成す
る。This air outlet 5 has a sound absorbing plate 9 made of urethane foam etc. on the indoor side.
A louver 8 is attached to the door sash 6 and the partition member 7 on the outdoor side, and a gap communicating with the space between the door inner panel and the outer panel is formed between the sound absorbing material 9 and the louver 8.
さらに、ドアインナパネルには車室内と連通ずる吸気穴
４を開設したものである。Furthermore, the door inner panel is provided with an intake hole 4 that communicates with the interior of the vehicle.
本考案は上記の通りの構造としたものであるから、車室
内と車室外とはドアインナパネルの吸気穴４、ドアの内
部室間及びドアウィンドの下側三角隅部の吹出口５を介
して通気可能な状態となり、停車中においても自然換気
作用を行っている。Since the present invention has the structure as described above, the interior of the vehicle and the exterior of the vehicle are connected through the air intake hole 4 in the door inner panel, the interior space of the door, and the air outlet 5 in the lower triangular corner of the door window. The vehicle is now ventilated, providing natural ventilation even when the vehicle is stationary.
さらに、車両が走行すると室内換気は積極的に行われる
。Furthermore, when the vehicle is running, indoor ventilation is actively carried out.
すなわち、車両の走行により第３図に示すように車体１
の側方を流れる気流がＡ矢印のように発生する。That is, as the vehicle runs, the vehicle body 1
An air current flows along the sides of the air as shown by arrow A.
これによりフロントピラ１０の部分には他の部所に比較
して大なる負圧が生ずる。As a result, a larger negative pressure is generated in the front pillar 10 than in other parts.
従って、ルーバ８のスリット部分より前記負圧によって
吸引作用を生起し、室内空気を積極的に車室外に誘出す
るものである。Therefore, a suction effect is generated by the negative pressure from the slit portion of the louver 8, and indoor air is actively drawn out of the vehicle interior.
また、前記の通りフロントピラ１０の部分の負圧が大き
いために、従来一般にドアウィンドの下側三角隅部の凹
所に渦巻の乱流が発生し、風切り騒音が生じていたが、
本考案はこの三角隅部には前記ルーバ８による吹出口５
を設けであるため、ルーバ８の鐘状の切り起し片が三角
隅部を通過する気流を外方に押し出す整流作用を行い、
三角隅部での渦巻乱流と風切り騒音の発生を抑制するも
のである。Furthermore, as mentioned above, due to the large negative pressure at the front pillar 10, vortex turbulence was generally generated in the recess at the lower triangular corner of the door window, causing wind noise.
In the present invention, this triangular corner has an air outlet 5 formed by the louver 8.
, the bell-shaped cut-and-raised piece of the louver 8 has a rectifying effect that pushes the airflow passing through the triangular corner outward.
This suppresses the generation of swirl turbulence and wind noise at the triangular corners.
以上のように本考案は車室内の換気を従来装置を増して
効果的に得ると共に、フロントピラに対接するドアウィ
ンドの下側三角隅部における風切り騒音の発生を低減す
る利点を有している。As described above, the present invention has the advantage of increasing the ventilation of the vehicle interior more effectively than conventional devices, and of reducing the occurrence of wind noise at the lower triangular corner of the door window that faces the front pillar. .
また本考案装置によってクォータピラやクォータパネル
部に吹出口を設ける必要がなくなり、車体後方側部のデ
ザインに自由度を持たせる利点もある。Furthermore, the device of the present invention eliminates the need to provide an air outlet in the quarter pillar or quarter panel, and has the advantage of allowing greater flexibility in the design of the rear side of the vehicle body.
