Description

本発明は、車室内の天井付近に空気吹き出し口を設けた車両用空調装置に関する。   The present invention relates to a vehicle air conditioner provided with an air outlet near the ceiling in a passenger compartment.

従来ワンボックスカーのような車両は、車室空間が一般の乗用車に比べて広いことから、広い車室内を効率よく冷暖房するために、天井付近に空気吹き出し口を設けて、空気調和装置(空調装置)により調和した空気を、天井付近の空気吹き出し口からも車室内へ吹き出すようにしている(例えば特許文献１，２，３)。   Conventional vehicles such as one-box cars have a larger cabin space than ordinary passenger cars.Therefore, in order to efficiently cool and heat a large cabin, an air outlet is provided near the ceiling, and an air conditioner (air conditioner) is installed. The air conditioned by the device is blown out from the air outlet near the ceiling into the passenger compartment (for example, Patent Documents 1, 2, and 3).

前記特許文献１に記載の車両用空調装置は、車両の天井部に設けられた冷房用ダクトの底面に、第１シャッタにより開閉自在な第１の吹き出し口が設けられており、冷房用ダクトの側面にも、第２シャッタにより開閉自在な第２の吹き出し口が設けられている。   The vehicle air conditioner described in Patent Document 1 is provided with a first air outlet that can be opened and closed by a first shutter on the bottom surface of a cooling duct provided in a ceiling portion of the vehicle. A second air outlet that can be opened and closed by the second shutter is also provided on the side surface.

また冷房装置の負荷度合いを検出する負荷度合い検出手段と、車両への日射方向を検知する日射センサが設けられていて、これら検出手段が検出した検出結果に基づいて第１・第２シャッタの開度を制御することにより、日射、負荷を考慮した最適な冷房空間が得られるようになっている。   In addition, a load degree detection means for detecting the load degree of the cooling device and a solar radiation sensor for detecting the direction of solar radiation to the vehicle are provided, and the first and second shutters are opened based on the detection results detected by these detection means. By controlling the degree, an optimal cooling space in consideration of solar radiation and load can be obtained.

一方特許文献２の車両の空調用エアダクト構造は、車室のルーフサイドに沿って直線状に設置されたエアダクトに、長手方向に間隔を存して複数のエア吹き出し口が設けられている。   On the other hand, in the air duct structure for air conditioning of a vehicle disclosed in Patent Document 2, a plurality of air outlets are provided in the air duct installed in a straight line along the roof side of the passenger compartment at intervals in the longitudinal direction.

エアダクトの中間位置に設けられたエア吹き出し口には、エアダクト内を流れる空気を分流するエア分流路が形成されていて、このエア分流路によりエアを分流することにより、各エア吹き出し口より車室内へほぼ均等にエアが吹き出せるように構成されている。   The air outlet provided at an intermediate position of the air duct is formed with an air distribution channel that divides the air flowing in the air duct. By dividing the air through the air distribution channel, each air outlet has a vehicle interior. Air is blown out almost evenly.

また特許文献３に記載の車両用空調ダクトは、空調ダクトの内部に、吹き出し口を取り囲むように堰を設けており、この堰には車両前方に開口する開口部が設けられている。   Moreover, the air conditioning duct for vehicles described in Patent Document 3 is provided with a dam inside the air conditioning duct so as to surround the air outlet, and this dam is provided with an opening that opens to the front of the vehicle.

そして車両後方より空調ダクト内を流通する空気が堰を通過する際、空気の一部が開口部より堰内部へ回り込むようにして、堰により囲まれた吹き出し口より車室内へ吹き出される空気を車両後方側寄りとすることにより、乗員の顔面に効果的に吹き出すことができるようになっている。
特開平１１−２４５６５１号公報 特開２００３−３２６９４３号公報 特開２００３−３４１２０号公報 When the air flowing through the air conditioning duct from the rear of the vehicle passes through the weir, the air blown into the vehicle interior from the outlet surrounded by the weir so that a part of the air circulates into the weir from the opening. By being closer to the rear side of the vehicle, it can be blown out effectively on the face of the occupant.
Japanese Patent Laid-Open No. 11-245651 JP 2003-326943 A JP 2003-34120 A

しかし前記特許文献１に記載のものは、冷房用ダクトの側面に形成された第２の吹き出し口より吹き出された空気を、天井面に設けたガイドベーンにより乗員の頭部側へ拡散させているため、天井面に設けたガイドベーンにより乗員の頭部と天井との間隔が狭くなり、車室内の居住性が低下する問題がある。   However, the device disclosed in Patent Document 1 diffuses the air blown from the second air outlet formed on the side surface of the cooling duct to the head side of the occupant by the guide vane provided on the ceiling surface. For this reason, the guide vanes provided on the ceiling surface reduce the distance between the head of the occupant and the ceiling, and there is a problem that the comfort in the passenger compartment decreases.

また吹き出し口を開閉するシャッタを駆動する駆動手段や、冷房装置の負荷度合いを検出する負荷度合い検出手段及び前記駆動手段を制御する制御手段等を必要とするため、部品点数が多くなってコスト高となる問題もある。   In addition, a driving means for driving a shutter that opens and closes the air outlet, a load degree detecting means for detecting the load degree of the cooling device, a control means for controlling the driving means, and the like are required. There is also a problem.

一方特許文献２に記載のものは、車両の後方から冷房ダクト内を流通する空気を吹き出し口よりそのまま吹き出しているため、吹き出し口より吹き出された空気の主流が車両の前方へ向ってしまい、その結果乗員の前側に当る空気が少ないため、涼感に欠ける問題がある。   On the other hand, since the thing which is described in patent document 2 blows out the air which distribute | circulates the inside of a cooling duct from the back of a vehicle as it is from a blower outlet, the mainstream of the air blown from the blower outlet will go to the front of a vehicle, As a result, the air hitting the front side of the occupant is less and there is a problem of lack of coolness.

また特許文献３に記載のものは、エアダクトの前端に達する空気に比べて、中間位置に設けられたエア吹き出し口より吹き出される空気が少ないため、乗員が着席する位置によって涼感にバラツキが生じる問題がある。   In addition, since the air described in Patent Document 3 has less air blown from the air outlet provided in the intermediate position than the air reaching the front end of the air duct, there is a problem that the cool feeling varies depending on the position where the occupant is seated. There is.

本発明は、かかる問題を改善するためになされたもので、乗員の周囲を包むように空気を吹き出すことができる空気吹き出し口を有する車両用空調装置を提供することを目的とするものである。   The present invention has been made to improve such a problem, and an object of the present invention is to provide a vehicle air conditioner having an air outlet that can blow out air so as to wrap around the passenger.

本発明の車両用空調装置は、車室内の天井付近に設置されたダクトに、空調装置本体により調和された空気を前記車室内に吹き出す空気吹き出し口を設けた車両用空調装置であって、前記空気吹き出し口を、前記ダクト内の空気流の下流側において空気を吹き出す第１空気吹き出し口と、前記第１空気吹き出し口より前記ダクト内の上流側に位置し、かつ前記第１空気吹き出し口より吹き出された空気に向けて空気を吹き出す第２空気吹き出し口とから形成し、さらに前記第１空気吹き出し口と前記第２空気吹き出し口の間に、前記ダクトの底面を凹入させることにより凹段部を形成し、かつ前記凹段部の前部に前記第１空気吹き出し口を、また前記凹段部の後部に前記第２空気吹き出し口を形成すると共に、前記第２空気吹き出し口に、空気の吹き出し方向がほぼ水平となるようにガイドするガイド手段を設けたものである。
The vehicle air conditioner according to the present invention is a vehicle air conditioner provided with an air outlet for blowing air conditioned by an air conditioner body into the duct in a duct installed near the ceiling in the vehicle interior, A first air outlet that blows out air on the downstream side of the air flow in the duct, an air outlet that is located upstream of the first air outlet and in the duct, and from the first air outlet A second air outlet that blows out air toward the blown air, and a concave step is formed by recessing the bottom surface of the duct between the first air outlet and the second air outlet. And forming the first air outlet at the front of the concave step, the second air outlet at the rear of the concave step, and emptying the second air outlet. Blowing direction of is provided with a guide for guiding means so as to be substantially horizontal.

前記構成により、第２空気吹き出し口より吹き出された空気が第１空気吹き出し口より例えば、乗員の前面側へ吹き出される空気に衝突することにより、下方向へと風向を変えながら乗員の前面側へ達するようになり、また第２空気吹き出し口より吹き出された空気の一部が例えば乗員の後方へ達するため、空調装置本体により調和された空気が乗員の周囲全体を囲むような雰囲気となり、これによって心地よい涼感が得られると共に、第１空気吹き出し口より車室内へ吹き出された空気が乗員の顔面に直接当ることないため、不快感を生じることもない。   With the above configuration, the air blown out from the second air blowing port collides with the air blown out from the first air blowing port, for example, to the front side of the occupant, thereby changing the wind direction downward while occupying the front side of the occupant. In addition, since a part of the air blown out from the second air outlet reaches the rear of the occupant, for example, the air conditioned by the air conditioner body surrounds the entire occupant, As a result, a pleasant cool feeling is obtained, and the air blown into the vehicle compartment from the first air outlet does not directly hit the occupant's face.

またダクトに空気吹き出し口を設けた簡単な構造のため、少ない部品点数で構成でき、これによって組み立て工数や部品コストの削減が図れる上、少ないスペースに容易に設置することができるため、省スペース化により車室内の居住性向上も図れるようになる。   In addition, since the duct has a simple structure with an air outlet, it can be configured with a small number of parts, which can reduce assembly man-hours and parts costs, and can be easily installed in a small space, saving space. This makes it possible to improve the comfort of the passenger compartment.

更に又、前記構成により、第２空気吹き出し口より吹き出された空気が第１空気吹き出し口へと向かうため、第１空気吹き出し口より吹き出される空気に確実に衝突させることができ、これによって第１、第２空気吹き出し口より吹き出される空気の風量バランスの設定が容易に行える。
 Furthermore, since the air blown out from the second air blowing port is directed to the first air blowing port by the above-described configuration, the air blown out from the first air blowing port can be reliably collided. 1, setting the air volume balance of air blown from the second air blowout port is Ru easy to.

本発明の車両用空調装置は、第１空気吹き出し口を、閉塞されたダクトの前端付近に形成すると共に、第１空気吹き出し口に、空気の吹き出し方向が斜め後方となるようにガイドするガイド部材を設けたものである。
 In the vehicle air conditioner of the present invention, the first air outlet is formed in the vicinity of the front end of the closed duct, and the guide member guides the first air outlet so that the air outlet direction is obliquely rearward. Ru der those provided.

前記構成により、ダクトの前端から第１空気吹き出し口までの距離や、ガイド部材の角度を変えることにより、第１空気吹き出し口より吹き出される空気の吹き出し方向を任意に設定することができるため、車室構造に合わせた空調設計が容易に行える。
 By changing the distance from the front end of the duct to the first air outlet and the angle of the guide member according to the above configuration, it is possible to arbitrarily set the blowing direction of the air blown from the first air outlet. air conditioning design tailored to the casing structure is Ru easy to.

本発明の車両用空調装置は、第１空気吹き出し口と第２空気吹き出し口間のダクト内に、第１空気吹き出し口と第２空気吹き出し口とから吹き出される空気の風量を調整する風量調整手段を設けたものである。   The vehicle air conditioner according to the present invention adjusts the air volume of air blown from the first air outlet and the second air outlet in the duct between the first air outlet and the second air outlet. Means are provided.

前記構成により、第１、第２空気吹き出し口より吹き出される空気の風量調整や、第１空気吹き出し口より吹き出される空気の風向調整が容易に行える。   With the above configuration, it is possible to easily adjust the air volume of air blown from the first and second air outlets and to adjust the air direction of air blown from the first air outlet.

本発明の車両用空調装置は、第１空気吹き出し口と第２空気吹き出し口を、ダクトと一体成形したものである。   The vehicle air conditioner of the present invention has a first air outlet and a second air outlet integrally formed with a duct.

前記構成により、第１、第２空気吹き出し口の形成が容易となる上、ダクト自体の軽量化が図れる。   With the above configuration, the first and second air outlets can be easily formed, and the weight of the duct itself can be reduced.

本発明の車両用空調装置によれば、空調装置本体により調和された空気が乗員の周囲全体を囲むように車室内に吹き出されるため、心地よい涼感が得られるようになる。   According to the vehicle air conditioner of the present invention, the air conditioned by the air conditioner body is blown out into the passenger compartment so as to surround the entire periphery of the occupant, so that a pleasant cool feeling can be obtained.

本発明の実施の形態を、図面を参照して詳述する。   Embodiments of the present invention will be described in detail with reference to the drawings.

図１は車両用空調装置のダクトが設けられた車室内の側面図、図２はダクトの斜視図、図３は同上面図、図４は同側面図、図５は図３のＡ−Ａ線に沿う断面図、図６及び図７は作用説明図である。   1 is a side view of a passenger compartment provided with a duct of a vehicle air conditioner, FIG. 2 is a perspective view of the duct, FIG. 3 is a top view thereof, FIG. 4 is a side view thereof, and FIG. FIG. 6 and FIG. 7 are cross-sectional views along the line, illustrating the operation.

図１は例えばワンボックスカーのような車両の車室１内を示すもので、車室両側の天井付近に、車両の前後方向にダクト２がほぼ水平に設置されている。   FIG. 1 shows the inside of a vehicle compartment 1 of a vehicle such as a one-box car, and a duct 2 is installed almost horizontally in the front-rear direction of the vehicle near the ceiling on both sides of the vehicle compartment.

ダクト２は、天井１ａの内面を覆う内装材（図示せず）の内側に設けられていて、車室１内に露出しないようになっており、ダクト２の空気流の前端側に設けられた空気吹き出し口３が車室１内に開口されており、空気吹き出し口３の位置は、車室１内に設置された中間座席（または後部座席）４に着席している乗員５の頭部上方付近となっている。   The duct 2 is provided inside an interior material (not shown) that covers the inner surface of the ceiling 1a and is not exposed in the passenger compartment 1, and is provided on the front end side of the airflow of the duct 2. An air outlet 3 is opened in the passenger compartment 1, and the position of the air outlet 3 is above the head of the occupant 5 seated in an intermediate seat (or rear seat) 4 installed in the passenger compartment 1. It is near.

ダクト２は図２ないし図５に示すように、縦幅に対し横幅が大きい扁平な角筒状となっていて、全体が樹脂により一体成形されており、ダクト２の後端部側は、空気を調和する空調装置本体(図示せず)に接続されている。   As shown in FIGS. 2 to 5, the duct 2 has a flat rectangular tube shape having a large width with respect to the vertical width, and the whole is integrally formed of resin. It is connected to an air conditioner body (not shown) that harmonizes.

ダクト２の前端側端面は、端板２ａに閉塞されており、前端側の下面に空気吹き出し口３が開口されている。   A front end side end face of the duct 2 is closed by an end plate 2a, and an air outlet 3 is opened on a lower face on the front end side.

空気吹き出し口３は、ダクト２の下面板２ｂと両側板２ｃの一部を凹入させることにより形成された凹段部２ｄの両端側に位置するよう２個所形成されており、図５に示すようにダクト２の空気流の下流側例えば前側の第１空気吹き出し口３ａの開口面積が大きく、そして例えばダクト２の空気流の上流側例えば後側の第２空気吹き出し口３ｂの開口面積が小さくなっている。   The air outlet 3 is formed at two locations so as to be positioned at both ends of the recessed step portion 2d formed by recessing the lower surface plate 2b and both side plates 2c of the duct 2, as shown in FIG. Thus, the opening area of the first air blowing port 3a on the downstream side, for example, the front side of the air flow in the duct 2 is large, and the opening area of the second air blowing port 3b on the upstream side, for example, the rear side of the air flow in the duct 2 is small. It has become.

前側の第１空気吹き出し口３ａには開口縁の内側に、第１空気吹き出し口３ａとほぼ同一の断面積を有する筒状のガイド部材３ｃがダクト２と一体に突設されている。   A cylindrical guide member 3c having substantially the same cross-sectional area as that of the first air blowing port 3a is projected from the front first air blowing port 3a integrally with the duct 2 inside the opening edge.

ガイド部材３ｃは、ダクト２の前端部に形成された空気溜り２ｅに達した空気が、乗員の前面側へ吹き出されるようにガイドするため、斜め前方へ傾斜するようダクト２内へ突出されており、ダクト２の前端面を閉塞する端板２ａからガイド部材３ｃの先端までの距離はＬ１に設定されている。   The guide member 3c is projected into the duct 2 so as to be inclined obliquely forward in order to guide the air reaching the air reservoir 2e formed at the front end portion of the duct 2 so as to be blown out to the front side of the occupant. The distance from the end plate 2a that closes the front end face of the duct 2 to the tip of the guide member 3c is set to L1.

後側の第２空気吹き出し口３ｂは、ダクト２の下面板２ｂと凹段部２ｄの上面との間の段差部分に開口されており、第２空気吹き出し口３ｂの開口縁には、第２空気吹き出し口３ｂとほぼ同一の断面積を有する筒状のガイド部材３ｄが、ダクト２内を後方に向けてほぼ水平に突設されている。   The rear second air outlet 3b is opened at a step portion between the lower surface plate 2b of the duct 2 and the upper surface of the recessed step portion 2d, and the second air outlet 3b has a second edge at the opening edge. A cylindrical guide member 3d having substantially the same cross-sectional area as the air outlet 3b is provided so as to protrude substantially horizontally with the inside of the duct 2 facing rearward.

ガイド部材３ｄの上下方向の幅はＬ２に設定されており、ガイド部材３ｄの上部とダクト２の上面板２ｆとの間隔はＬ３に設定されている。   The vertical width of the guide member 3d is set to L2, and the distance between the upper part of the guide member 3d and the upper surface plate 2f of the duct 2 is set to L3.

また第１空気吹き出し口３ａと第２空気吹き出し口３ｂの間に位置するダクト２内には、風量調整手段６が設けられている。   An air volume adjusting means 6 is provided in the duct 2 located between the first air outlet 3a and the second air outlet 3b.

この風量調整手段６は、中間部がピン６ａによりダクト２の両側板２ｃに回動自在に支承された長方形状の弁板６ｂより形成されていて、ノブ等の操作手段（図示せず）によりピン６ａを中心に弁板６ｂを回動することにより、第１空気吹き出し口３ａより吹き出される空気の風量と、第２空気吹き出し口３ｂより吹き出される空気の風量を任意に調整できるようになっている。   The air volume adjusting means 6 is formed of a rectangular valve plate 6b whose middle part is rotatably supported on both side plates 2c of the duct 2 by pins 6a, and is operated by an operating means (not shown) such as a knob. By rotating the valve plate 6b around the pin 6a, the amount of air blown from the first air outlet 3a and the amount of air blown from the second air outlet 3b can be arbitrarily adjusted. It has become.

次に前記構成された車両用空調装置の作用を説明する。   Next, the operation of the vehicle air conditioner constructed as described above will be described.

車室１内の天井１ａ付近に設置されたダクト２の空気吹き出し口３は、例えば中間の座席４に着席する乗員５や、後部の座席（図示せず）に着席する乗員５の頭部上方に位置している。   The air outlet 3 of the duct 2 installed near the ceiling 1a in the passenger compartment 1 is located above the head of the occupant 5 seated in the intermediate seat 4 or the occupant 5 seated in the rear seat (not shown), for example. Is located.

この状態で図示しない空調装置本体により調和された空気が、ダクト２の後端側からダクト２内へ送り込まれると、調和された空気はダクト２内を前方へと流通し、ダクト２の前端側に設けられた空気吹き出し口３に達する。   In this state, when air conditioned by an air conditioner main body (not shown) is sent into the duct 2 from the rear end side of the duct 2, the conditioned air circulates forward in the duct 2 and the front end side of the duct 2. It reaches the air outlet 3 provided in.

ダクト２の下面に開口された空気吹き出し口３は、乗員５の頭部の前方に位置する第１空気吹き出し口３ａと、頭部の後方に位置する第２空気吹き出し口３ｂより構成されていて、ダクト２前端の空気溜り２ｅに達した空気は、第１空気吹き出し口３ａの内側に設けられたガイド部材３ｃによりガイドされて、第１空気吹き出し口３ａより乗員５の前頭部方向へ図６の矢印Ｂに示すように吹き出される。   The air outlet 3 opened on the lower surface of the duct 2 includes a first air outlet 3a located in front of the head of the occupant 5 and a second air outlet 3b located behind the head. The air that has reached the air reservoir 2e at the front end of the duct 2 is guided by a guide member 3c provided inside the first air outlet 3a, and is directed toward the front of the occupant 5 from the first air outlet 3a. 6 is blown out as indicated by arrow B.

同時に乗員５の後方に位置する第２空気吹き出し口３ｂに達した空気は、第２空気吹き出し口３ｂの内側に設けられたガイド部材３ｄにガイドされて、第２空気吹き出し口３ｂより水平方向、すなわち第１空気吹き出し口３ａに向けて図６の矢印Ｃに示すように吹き出される。   At the same time, the air that has reached the second air outlet 3b located behind the occupant 5 is guided by a guide member 3d provided inside the second air outlet 3b, and in a horizontal direction from the second air outlet 3b. That is, it blows out toward the first air outlet 3a as shown by an arrow C in FIG.

そして第２空気吹き出し口３ｂより水平方向に吹き出された空気流Ｃは、第１空気吹き出し口３ａより乗員５の前頭部方向へ吹き出される空気流Ｂに衝突するため、図７に示す空気流Ｄとなって下方向へと風向を変えながら乗員５の前面側へ達するようになり、これによって第１空気吹き出し口３aより車室１内へ吹き出された空気流Ｂは、乗員５の顔面に直接当ることない。   Since the air flow C blown out in the horizontal direction from the second air blowing port 3b collides with the air flow B blown out from the first air blowing port 3a toward the frontal area of the occupant 5, the air shown in FIG. The air flow B reaches the front side of the occupant 5 while changing the wind direction downward, so that the air flow B blown into the passenger compartment 1 from the first air outlet 3a is the face of the occupant 5 Do not hit directly.

また第２空気吹き出し口３ｂより吹き出された空気流Ｃの一部は、図７の矢印Ｅに示すように乗員５の後頭部付近へも吹き出されることから、乗員５の前後に吹き出された空気は、乗員５の周囲全体を囲むような雰囲気となるため、心地よい涼感が得られるようになる。   A part of the air flow C blown out from the second air outlet 3b is also blown out to the vicinity of the back of the occupant 5 as shown by an arrow E in FIG. Since the atmosphere surrounds the entire periphery of the occupant 5, a comfortable cool feeling can be obtained.

一方、風量調整手段６の弁板６ｂを中立位置に調整しておくことにより、開口面積の大きい第１空気吹き出し口３ａからより多くの空気が吹き出されるようになるため、シートバック４ａに妨げられることなく乗員５の前側をより効果的に冷暖房できるが、風量調整手段６の弁板６ｂの開度を調整して、第１空気吹き出し口３ａ側に達する空気の風量を減少させると、第２空気吹き出し口３ｂより吹き出される空気の風量が増加するため、乗員５の後方へ吹き出される空気の風量が増すと同時に、第１空気吹き出し口３ａより吹き出される空気の風量が減少するように調整することができる。   On the other hand, by adjusting the valve plate 6b of the air volume adjusting means 6 to the neutral position, more air is blown out from the first air outlet 3a having a large opening area, which hinders the seat back 4a. The front side of the occupant 5 can be cooled and heated more effectively without being reduced, but if the opening of the valve plate 6b of the air volume adjusting means 6 is adjusted to reduce the air volume reaching the first air outlet 3a side, 2 Since the air volume blown from the air outlet 3b increases, the air volume blown rearward of the occupant 5 increases, and at the same time, the air volume blown from the first air outlet 3a decreases. Can be adjusted.

すなわち風量調整手段６により第１空気吹き出し口３ａより吹き出される空気の風量と、第２空気吹き出し口３ｂより吹き出される空気の風量(分配量)を調整することにより、第１空気吹き出し口３ａより吹き出される空気の風向を任意に変えることができると同時に、乗員５の後方へ吹き出される空気の風量を増減することができるため、乗員５の前方を集中的に冷暖房したり、乗員５の背中付近をより多く冷暖房する等の操作が容易に行えるようになる。   That is, the air volume adjusting means 6 adjusts the air volume blown from the first air outlet 3a and the air volume (distribution amount) of air blown from the second air outlet 3b to thereby adjust the first air outlet 3a. The air direction of the air blown out can be arbitrarily changed, and at the same time, the amount of air blown out to the rear of the occupant 5 can be increased or decreased. It is possible to easily perform operations such as air-conditioning more and more in the vicinity of the back.

なお前記実施の形態では、ダクト１に、車室２内の中間の座席４に着席する乗員５または後部の座席に着席する乗員５に向けて空気を吹き出す空気吹き出し口３を設けたが、中間の座席４に着席する乗員５と後部の座席に着席する乗員５に同時に空気が吹き出せるように、中間の座席４に着席する乗員５と後部の座席に着席する乗員５の頭部上方に、それぞれ空気吹き出し口３を設けるようにしてもよい。また、空気吹出し口３の第１空気吹出し口３ａは、車室の横方向側部側に位置させ、同じく第２空気吹き出し口３ｂは車室中央側に位置させてもよい。   In the above-described embodiment, the duct 1 is provided with the air outlet 3 that blows out air toward the occupant 5 seated in the intermediate seat 4 in the passenger compartment 2 or the occupant 5 seated in the rear seat. Above the head of the occupant 5 seated in the intermediate seat 4 and the occupant 5 seated in the rear seat so that air can be blown out simultaneously to the occupant 5 seated in the seat 4 and the occupant 5 seated in the rear seat, An air outlet 3 may be provided for each. Further, the first air outlet 3a of the air outlet 3 may be positioned on the lateral side of the vehicle compartment, and the second air outlet 3b may be positioned on the center side of the passenger compartment.

本発明の車両用空調装置は、空調装置本体により調和された空気が乗員の周囲全体を囲むように車室内に吹き出されることにより、心地よい涼感が得られるため、車室内の天井付近に空気吹き出し口を設けた車両用空調装置に最適である。   In the vehicle air conditioner of the present invention, since air conditioned by the air conditioner body is blown out into the vehicle interior so as to surround the entire periphery of the passenger, a comfortable cool feeling can be obtained. It is most suitable for a vehicle air conditioner with a mouth.
