従来、自動車などの車両に用いられる空調装置において、風を吹き出す吹出口に備えられる風向調整装置は、空調風吹出装置、エアアウトレット、ベンチレータ、レジスタなどとも呼ばれ、例えばインストルメントパネルやセンターコンソール部などの車両の各部に設置され、冷暖房による快適性能の向上に寄与している。 2. Description of the Related Art Conventionally, in an air conditioner used for a vehicle such as an automobile, an airflow direction adjusting device provided at an air outlet for blowing out air is also called an air conditioning air blowing device, an air outlet, a ventilator, a register, etc., for example, an instrument panel or a center console section. It is installed in each part of the vehicle such as, and contributes to the improvement of comfort performance by heating and cooling.

例えば、車室レイアウト上の制限により、側部用の風向調整装置が乗員着座位置から離れた位置、主に車両側壁部などに設定される場合がある。この風向調整装置は、空調装置と接続されて前後方向に空調風を導くダクトに車両前後方向と交差する方向(車幅方向)に開口された吹出口に取り付けられている。また、この風向調整装置は、風向調整用のフィンを複数、前後方向に回動可能に備えている。そして、ダクトから送られてくる空調風が吹出口から車室内へ向けて吹き出される(例えば、特許文献1参照。)。 For example, there are cases where the wind direction adjusting device for the side portion is set at a position away from the occupant seating position, mainly on the side wall portion of the vehicle, etc. due to restrictions on the vehicle compartment layout.

上記のような側部用の風向調整装置では、インストルメントパネルなどに設けられた風向調整装置と異なり、空調装置(HVAC)から距離があることから、ダクト内を送風される間にただでさえ風速が弱まってしまう上、ダクトの最下流に設けられた壁に突き当たった空調風がダクト内で乱流を生じ、車室内へ吹き出す風量が減少する。そのため、風向調整用のフィンは、吹き出される空調風の風速を均一にする作用を有するに過ぎず、回動させても任意の方向へ充分な量の空調風を送ることが困難である。 Unlike the airflow direction adjusting device provided on the instrument panel or the like, the airflow direction adjusting device for the side portion as described above has a distance from the air conditioner (HVAC). In addition to the weakening of the wind speed, the air-conditioning wind that hits the wall provided on the most downstream side of the duct causes turbulence in the duct, and the amount of air blown into the passenger compartment decreases. Therefore, the fins for adjusting the wind direction only have the function of making the wind speed of the conditioned air blown out uniform, and it is difficult to send a sufficient amount of the conditioned air in any direction even when rotated.

本発明は、このような点に鑑みなされたもので、レイアウト上の制限がある場合でも風向の適切な調整が可能な風向調整装置及びこれを備えた空調装置を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an airflow direction adjusting device capable of appropriately adjusting the airflow direction even when there is a layout limitation, and an air conditioner including the airflow direction adjusting device.

図5ないし図7に示すハウジング21は、例えば枠状に形成されている。本実施の形態において、このハウジング21は、空間部39に収容可能な四角形枠状となっている。すなわち、このハウジング21は、一対の側面部44,45と一対の端面部46,47とを一体的に備えている。また、このハウジング21には、取付面部48が一体的に形成されている。さらに、このハウジング21には、遮蔽部49が一体的に形成されている。 The housing 21 shown in FIGS. 5 to 7 is formed in a frame shape, for example. In the present embodiment, the housing 21 has a rectangular frame shape that can be accommodated in the space 39. That is, the housing 21 integrally includes the pair of side surface portions 44 and 45 and the pair of end surface portions 46 and 47. A mounting surface portion 48 is integrally formed on the housing 21. Further, the housing 21 is integrally formed with a shielding portion 49.

側面部44,45は、本実施の形態において、例えば吹出口31の上下縁部に沿って形成され、フィニッシャ15の支持受部32の支持壁部34,35に近接して位置している。 In the present embodiment, the side surface portions 44 and 45 are formed, for example, along the upper and lower edges of the outlet 31 and are located close to the support wall portions 34 and 35 of the support receiving portion 32 of the finisher 15.

また、一方の端面部46は、吹出口31の一端部に沿って形成され、他方の端面部47は、吹出口31の他端部に対して他端側に離れた位置に形成されている。本実施の形態において、一方の端面部46は、吹出口31の前縁部、すなわち吹出部27の前縁部、換言すればダクト本体部25の壁部26及びフィニッシャ15の前側の区画壁部36に近接して位置し、他方の端面部47は、吹出口31の後縁部から後側に離れて吹出部27の後縁部及びフィニッシャ15の後側の区画壁部37に近接して位置している。このため、ハウジング21は、吹出口31のダクト本体部25により空調風を導く所定方向、本実施の形態では前後方向の寸法L1が、吹出口31の寸法L2よりも長く形成されている(L1>L2、図5)。そして、各端面部46,47には、ハウジング21の回動用の回動軸51,52が吹出口31側とは反対側の面に突設されている。これら回動軸51,52は、フィニッシャ15の支持受部32(区画壁部36,37)に設けられた例えば丸孔状の受け部54,55に挿入されることでフィニッシャ15(吹出口31)に対してハウジング21が回動可能に軸支される。 Further, one end surface portion 46 is formed along one end of the outlet 31 and the other end surface 47 is formed at a position apart from the other end of the outlet 31 on the other end side. .. In the present embodiment, the one end surface portion 46 is the front edge portion of the blowout port 31, that is, the front edge portion of the blowout portion 27, in other words, the wall portion 26 of the duct body portion 25 and the partition wall portion on the front side of the finisher 15. The other end face portion 47 is located close to the rear end portion of the blowout portion 27 and the partition wall portion 37 on the rear side of the finisher 15. positioned. For this reason, the housing 21 is formed such that the dimension L1 in the predetermined direction for guiding the conditioned air by the duct main body 25 of the outlet 31, that is, the front-rear direction in the present embodiment is longer than the dimension L2 of the outlet 31 (L1. >L2, FIG. 5). Then, on each of the end surface portions 46 and 47, rotary shafts 51 and 52 for rotating the housing 21 are provided so as to project from the surface on the side opposite to the outlet 31 side. The rotary shafts 51 and 52 are inserted into, for example, round hole-shaped receiving portions 54 and 55 provided in the support receiving portion 32 (partitioning wall portions 36 and 37) of the finisher 15 so that the finisher 15 (the outlet 31 ), the housing 21 is pivotally supported.

取付面部48は、端面部46,47の間にてこれら端面部46,47に対して平行(略平行も含む)に位置している。この取付面部48には、端面部46との間に、横ルーバ18が橋架されている。この取付面部48は、端面部46に対して、吹出口31の寸法L2と略等しい距離離れた位置に形成されている。したがって、ハウジング21には、側面部44,45、端面部46及び取付面部48に囲まれる通気部57が形成されている。 The mounting surface portion 48 is located between the end surface portions 46 and 47 in parallel (including substantially parallel) to the end surface portions 46 and 47. A lateral louver 18 is bridged between the mounting surface portion 48 and the end surface portion 46. The mounting surface portion 48 is formed at a position separated from the end surface portion 46 by a distance substantially equal to the dimension L2 of the outlet 31. Therefore, the housing 21 is formed with a ventilation portion 57 surrounded by the side surface portions 44 and 45, the end surface portion 46, and the mounting surface portion 48.

遮蔽部49は、吹出部27にて壁部26側、本実施の形態では後側から前側に向かって延びている。本実施の形態において、この遮蔽部49は、ハウジング21の端面部47から吹出口31側(通気部57側)に向かって壁状に延びて形成されている。例えば、この遮蔽部49の長手方向、本実施の形態では前後方向の寸法L3は、ハウジング21の寸法L1よりも小さく、本実施の形態ではさらに吹出口31の寸法L2よりも小さい(L1>L2>L3、図5)。また、この遮蔽部49の寸法L3と吹出口31の寸法L2との和は、ハウジング21の寸法L1と略等しい(L1≒L2+L3)。さらに、この遮蔽部49は、側面部44,45、端面部47、及び取付面部48と連続して形成されている。このため、ハウジング21は、通気部57に対して長手方向に隣接する位置の吹出口31側が遮蔽部49により覆われて閉塞されている。この遮蔽部49は、一部の縦ルーバ16、本実施の形態では壁部26側の複数の縦ルーバ16に対して、空調風の吹き出し方向下流側、すなわち車室側(本実施の形態では左側)に所定距離、離れて対向して位置している。すなわち、この遮蔽部49により車室側が覆われた縦ルーバ16は、吹出口31に対して露出しない、第1フィンとしての非露出フィンである非露出縦ルーバ16aとなっている。本実施の形態において、非露出縦ルーバ16aは、例えば3つ設定され、遮蔽部49及びフィニッシャ15により車室側が覆われて位置している。換言すれば、縦ルーバ16のうち、非露出縦ルーバ16a以外のものは、通気部57を介して吹出口31に露出する、第2フィンとしての露出フィンである露出縦ルーバ16bとなっている。つまり、ハウジング21には、通気部57に対して長手方向に隣接する位置に、壁部26から吹出口31へと、通気部57に連通して閉じ通路58が形成されている。閉じ通路58は、縦ルーバ16を挟んでダクト本体部25と対向する側、本実施の形態では車室側に位置し、端部が壁部26により閉塞されているとともに、非露出縦ルーバ16aを収容している。また、遮蔽部49の背面側、すなわち縦ルーバ16(非露出縦ルーバ16a)と対向する側には、空調風を吹出口31(通気部57)側へとガイドするガイド部59が形成されている。このガイド部59は、本実施の形態において、例えば遮蔽部49に形成された複数の溝部とするが、リブなどとすることもできる。このガイド部59は、ダクト本体部25により空調風を導く所定方向、本実施の形態では前後方向に沿って形成され、上下に複数設定されている。 The shielding portion 49 extends from the blow-out portion 27 toward the wall portion 26, that is, from the rear side to the front side in the present embodiment. In the present embodiment, the shielding portion 49 is formed so as to extend like a wall from the end surface portion 47 of the housing 21 toward the outlet 31 side (the ventilation portion 57 side). For example, the length L3 of the shielding portion 49 in the longitudinal direction, in the present embodiment, the front-rear direction, is smaller than the dimension L1 of the housing 21, and in the present embodiment, it is smaller than the dimension L2 of the outlet 31 (L1>L2). >L3, FIG. 5). The sum of the dimension L3 of the shielding portion 49 and the dimension L2 of the outlet 31 is substantially equal to the dimension L1 of the housing 21 (L1≈L2+L3). Further, the shielding portion 49 is formed continuously with the side surface portions 44 and 45, the end surface portion 47, and the mounting surface portion 48. Therefore, the housing 21 is closed by being covered with the shielding portion 49 on the side of the air outlet 31 that is adjacent to the ventilation portion 57 in the longitudinal direction. The shielding portion 49 is provided on a part of the vertical louvers 16 and, in the present embodiment, with respect to the plurality of vertical louvers 16 on the wall portion 26 side, on the downstream side in the blowing direction of the conditioned air, that is, on the vehicle cabin side (in the present embodiment, in the present embodiment). It is located at a predetermined distance and is opposed to the left side). That is, the vertical louver 16 whose interior side is covered by the shielding portion 49 is a non-exposed vertical louver 16a that is a non-exposed fin as the first fin that is not exposed to the air outlet 31. In the present embodiment, for example, three non-exposed vertical louvers 16a are set, and the vehicle compartment side is positioned so as to be covered by the shielding portion 49 and the finisher 15. In other words, among the vertical louvers 16, those other than the non-exposed vertical louvers 16a are exposed vertical louvers 16b that are exposed fins as second fins that are exposed to the air outlet 31 via the ventilation portion 57. .. That is, a closed passage 58 is formed in the housing 21 at a position adjacent to the ventilation portion 57 in the longitudinal direction, from the wall portion 26 to the outlet 31 and in communication with the ventilation portion 57. The closed passage 58 is located on the side facing the duct main body 25 with the vertical louver 16 in between, that is, on the passenger compartment side in the present embodiment, and the end is closed by the wall 26 and the non-exposed vertical louver 16a. Are housed. Further, on the back side of the shielding part 49, that is, on the side facing the vertical louver 16 (non-exposed vertical louver 16a), a guide part 59 for guiding the conditioned air to the outlet 31 (ventilation part 57) side is formed. There is. In the present embodiment, the guide portion 59 is, for example, a plurality of groove portions formed in the shield portion 49, but may be a rib or the like. The guide portions 59 are formed along a predetermined direction in which the duct main body portion 25 guides the conditioned air, that is, the front-rear direction in the present embodiment, and a plurality of guide portions 59 are set vertically.

そして、風向調整装置10は、予め成形されたハウジング21内に縦ルーバ16をそれぞれ取り付けるとともに、これら縦ルーバ16をリンク17により連結する。さらに、この縦ルーバ16及びリンク17を取り付けたハウジング21を、予め成形されたフィニッシャ15の支持受部32に対して、回動軸51,52を受け部54,55に嵌合させる。この結果、ハウジング21が支持受部32により囲まれる空間部39内に回動可能に配置され、風向調整装置10が完成される。 Then, the wind direction adjusting device 10 attaches the vertical louvers 16 in the preformed housing 21 and connects the vertical louvers 16 by the link 17. Further, the housing 21 to which the vertical louver 16 and the link 17 are attached is fitted to the receiving portions 54 and 55 of the rotary shafts 51 and 52 with respect to the support receiving portion 32 of the finisher 15 which is formed in advance. As a result, the housing 21 is rotatably arranged in the space 39 surrounded by the support receiving portion 32, and the wind direction adjusting device 10 is completed.

この後、完成された風向調整装置10を、予め設置されたダクト11に対して、フィニッシャ15により吹出部27を覆うように取り付けることで、空調装置12が完成する。この状態で、ダクト11のダクト本体部25に設けられた壁部26に対して、風向調整装置10の遮蔽部49側が近接して位置し、壁部26と遮蔽部49とによって、ダクト本体部25(ダクト11)の下流端の位置に、コ字状に折り返された閉じ通路58が形成される。この状態で、縦ルーバ16のうち、非露出縦ルーバ16aに対向して遮蔽部49が位置し、縦ルーバ16の残りの他である露出縦ルーバ16bと、横ルーバ18との位置に吹出口31が位置する。そして、操作ノブ41を摘んだ乗員がこの操作ノブ41を前後に振ることでリンク17を介して互いに連結された縦ルーバ16が、互いに略平行な角度を保ちつつ前後に回動する。また、操作ノブ41を摘んだ乗員がこの操作ノブ41を上下に振ることでハウジング21がフィニッシャ15に対して回動し、縦ルーバ16とともに横ルーバ18が上下に回動する。 After that, the completed wind direction adjusting device 10 is attached to the duct 11 installed in advance so that the finisher 15 covers the blowout portion 27, whereby the air conditioner 12 is completed. In this state, the shield portion 49 side of the wind direction adjusting device 10 is located close to the wall portion 26 provided in the duct body portion 25 of the duct 11, and the duct body portion is formed by the wall portion 26 and the shield portion 49. A closed passage 58 folded back in a U shape is formed at a position of the downstream end of 25 (duct 11). In this state, in the vertical louver 16, the shielding portion 49 is located so as to face the non-exposed vertical louver 16a, and the outlet is provided at the position of the exposed vertical louver 16b, which is the other remaining vertical louver 16, and the horizontal louver 18. 31 is located. Then, the occupant picking up the operation knob 41 swings the operation knob 41 back and forth, so that the vertical louvers 16 connected to each other via the link 17 rotate back and forth while maintaining angles substantially parallel to each other. The occupant picking up the operation knob 41 swings the operation knob 41 up and down, whereby the housing 21 rotates with respect to the finisher 15, and the vertical louver 16 and the horizontal louver 18 rotate up and down.

そして、風向調整装置10は、空調装置本体から供給された空調風がダクト11のダクト本体部25により後方へと導かれ、吹出部27から風向調整装置10側へと流れる。このとき、吹出部27からハウジング21の通気部57を介して吹出口31へと直接流れる主流の空調風は、縦ルーバ16の露出縦ルーバ16bの整流面に沿って整流される。また、壁部26に突き当たった空調風は、この壁部26に近接して位置する縦ルーバ16の各非露出縦ルーバ16aの整流面に沿って遮蔽部49側へと流れ、壁部26と遮蔽部49との間のコ字状の閉じ通路58に溜められ、遮蔽部49に沿って、この遮蔽部49によってダクト本体部25により空調風を導く方向と反対方向へと、すなわち吹出口31へとガイド部59によりガイドされる。 Then, in the wind direction adjusting device 10, the conditioned air supplied from the air conditioner main body is guided rearward by the duct main body part 25 of the duct 11 and flows from the blowout part 27 to the wind direction adjusting device 10 side. At this time, the mainstream conditioned air that directly flows from the air outlet 27 to the air outlet 31 through the ventilation portion 57 of the housing 21 is rectified along the rectifying surface of the exposed vertical louver 16b of the vertical louver 16. Further, the air-conditioning wind that hits the wall portion 26 flows toward the shielding portion 49 side along the rectifying surface of each non-exposed vertical louver 16a of the vertical louver 16 located near the wall portion 26, and the wall portion 26 and It is stored in a U-shaped closed passage 58 between the shield portion 49 and the shield portion 49, along the shield portion 49, in the direction opposite to the direction in which the duct main body portion 25 guides the conditioned air, that is, the outlet 31. It is guided by the guide part 59.

この後、空調風は、横ルーバ18の整流面に沿って整流され、吹出口31から乗員側、すなわち車室内に吹き出される。 Thereafter, the conditioned air is rectified along the rectifying surface of the lateral louver 18 and is blown out from the outlet 31 to the passenger side, that is, the passenger compartment.

例えば、図1に示す中立位置から、図2に示すように縦ルーバ16を前方に振った場合、吹出部27の縦ルーバ16の露出縦ルーバ16bの整流面に沿って前方に整流される主流の空調風に対して、壁部26に突き当たって閉じ通路58を縦ルーバ16の各非露出縦ルーバ16aの整流面に沿って遮蔽部49側を介して吹出口31へと、ダクト本体部25により空調風を導く所定方向とは反対方向に向かってガイド部59により前方にガイドされて流速が増した空調風が混ざり、縦ルーバ16の振り角度よりも大きく前方に風向が調整される。なお、本実施の形態においては、縦ルーバ16を前方に最大に振った場合、隣り合うすべての縦ルーバ16どうしが互いに重なることで、空調風を遮断(シャット)する。 For example, when the vertical louver 16 is swung forward from the neutral position shown in FIG. 1 as shown in FIG. 2, the main flow is rectified forward along the rectifying surface of the exposed vertical louver 16b of the vertical louver 16 of the blowout part 27. Against the conditioned air, the closed passage 58 hitting the wall portion 26 is closed along the rectifying surface of each unexposed vertical louver 16a of the vertical louver 16 to the air outlet 31 via the shielding portion 49 side, and the duct main body 25 As a result, the conditioned air, which has been guided forward by the guide portion 59 and has an increased flow velocity, is mixed in a direction opposite to the predetermined direction in which the conditioned air is guided, and the wind direction is adjusted to be larger than the swing angle of the vertical louver 16. In the present embodiment, when the vertical louvers 16 are swung to the maximum forward, all the adjacent vertical louvers 16 overlap with each other to shut off the conditioned air.

同様に、図1に示す中立位置から、図3に示すように縦ルーバ16を後方に振った場合、吹出部27の縦ルーバ16の露出縦ルーバ16bの整流面に沿って後方に整流される主流の空調風に対して、壁部26に突き当たって閉じ通路58を縦ルーバ16の各非露出縦ルーバ16aの整流面に沿って遮蔽部49側を介して吹出口31へと、ダクト本体部25により空調風を導く所定方向とは反対方向に向かってガイド部59により前方にガイドされて流速が増した空調風が混ざり、縦ルーバ16の振り角度よりも大きく後方に風向が調整される。 Similarly, when the vertical louver 16 is swung rearward as shown in FIG. 3 from the neutral position shown in FIG. 1, the vertical louver 16 of the outlet 27 is straightened rearward along the straightening surface of the exposed vertical louver 16b. With respect to the mainstream conditioned air, the closed passage 58 is abutted against the wall portion 26, and the duct main body portion is provided along the straightening surface of each unexposed vertical louver 16a of the vertical louver 16 through the shielding portion 49 side to the air outlet 31. The air-conditioning air, which has been guided forward by the guide portion 59 and has an increased flow velocity, is mixed in a direction opposite to the predetermined direction in which the air-conditioning air is guided by 25, and the wind direction is adjusted rearward to a degree larger than the swing angle of the vertical louver 16.

上述したように、上記第1の実施の形態によれば、所定方向に沿って吹出部27に縦ルーバ16を複数配置するとともに、フィンを挟んでダクトのダクト本体部と対向する側に、端部がダクトの壁部により閉塞される閉じ通路を形成することで、フィンにより風向を調整する際に、壁部26に突き当たって閉じ通路58を流れる空調風が、縦ルーバ16(露出縦ルーバ16b)により直接風向制御される空調風の流速を高め、レイアウト上の制限がある場合でも風向の適切な調整が可能となる。 As described above, according to the first embodiment, a plurality of vertical louvers 16 are arranged in the blowout portion 27 along the predetermined direction, and the end is provided on the side facing the duct main body portion of the duct with the fin interposed therebetween. By forming a closed passage that is closed by the wall portion of the duct, the conditioned air that strikes the wall portion 26 and flows through the closed passage 58 when adjusting the wind direction by the fins flows through the vertical louver 16 (exposed vertical louver 16b. ) Makes it possible to increase the flow velocity of the conditioned air which is directly controlled by the air flow direction, and it becomes possible to appropriately adjust the air flow direction even when there is a layout limitation.

また、閉じ通路58において、ダクト11の壁部26側の一部の縦ルーバ16(非露出縦ルーバ16a)の吹き出し方向下流側を遮蔽部49により覆い、少なくとも残りの他の縦ルーバ16(露出縦ルーバ16b)の吹き出し方向下流側に吹出口31を開口することで、縦ルーバ16により風向を調整する際に、壁部26に突き当たって閉じ通路58を流れる空調風を、遮蔽部49から吹出口31側へと整流して、縦ルーバ16(露出縦ルーバ16b)により直接風向制御される空調風の流速をより効果的に高めることができる。 Further, in the closed passage 58, a part of the vertical louvers 16 (non-exposed vertical louvers 16a) on the side of the wall portion 26 of the duct 11 on the downstream side in the blowing direction is covered with the shielding portion 49, and at least the other vertical louvers 16 (exposed). By opening the air outlet 31 on the downstream side of the vertical louver 16b) in the blowing direction, when adjusting the wind direction by the vertical louver 16, the conditioned air that abuts the wall portion 26 and flows through the closed passage 58 is blown from the shielding portion 49. By rectifying the air toward the outlet 31 side, it is possible to more effectively increase the flow velocity of the conditioned air whose wind direction is directly controlled by the vertical louver 16 (exposed vertical louver 16b).

すなわち、空調装置本体からの空調風の経路がレイアウトの制限上遠くなると、風速が弱まって乗員のターゲットポイントに空調風が届きにくくなるため、閉じ通路58(遮蔽部49及びその背面側の縦ルーバ16)によって壁部26を利用して空調風を溜めて流速の低下を抑制し、乗員のターゲットポイントに空調風の束を向けることができる。このため、車両のレイアウトによって吹出口31を乗員のターゲットポイントから離れた位置にしかレイアウトできない条件であっても、閉じ通路58(遮蔽部49及びその背面側の縦ルーバ16)によって風向制御性をリカバリできる。 That is, if the air-conditioning air path from the air-conditioning system main body becomes far due to the layout limitation, the air speed weakens and it becomes difficult for the air-conditioning air to reach the occupant's target point, so the closed passage 58 (the shield part 49 and the vertical louvers on the rear side thereof). 16) makes it possible to collect the conditioned air using the wall portion 26 and suppress the decrease in the flow velocity, and direct the conditioned air bundle to the target point of the occupant. For this reason, even if the layout of the vehicle allows the outlet 31 to be laid out only at a position away from the target point of the occupant, the closed passage 58 (the shielding portion 49 and the vertical louver 16 on the rear side thereof) provides the wind direction controllability. Can be recovered.

また、遮蔽部49の縦ルーバ16(非露出縦ルーバ16a)に対向する位置に、空調風を吹出口31側へとガイドするガイド部59を設けることで、ダクト11の壁部26に突き当たって遮蔽部49により吹出口31へと流れる空調風の流速をガイド部59によって高め、風向をより適切に調整可能になるとともに、風切り音(笛吹音)などの雑音の発生を抑制できる。 Further, by providing a guide part 59 for guiding the conditioned air to the outlet 31 side at a position facing the vertical louver 16 (non-exposed vertical louver 16a) of the shielding part 49, the wall part 26 of the duct 11 can be hit. By the guide part 59, the flow velocity of the conditioned air flowing to the air outlet 31 is increased by the shielding part 49, the wind direction can be adjusted more appropriately, and the generation of noise such as wind noise (whistling noise) can be suppressed.

さらに、フィニッシャ15の吹出口31の側方の背面側にハウジング21を設定できるため、フィニッシャ15のデザインの幅が広がる。 Further, since the housing 21 can be set on the rear side of the finisher 15 on the side of the outlet 31, the design of the finisher 15 can be widened.

また、遮蔽部49は、ハウジング21に一体に設けることで、遮蔽部49を形成するための専用の成形型などが不要であり、低コストで風向調整装置10を製造できる。 In addition, since the shielding part 49 is integrally provided on the housing 21, a dedicated mold or the like for forming the shielding part 49 is not required, and the wind direction adjusting device 10 can be manufactured at low cost.

そして、例えば車両の車室の側部など、スペースが取りにくくレイアウト上に制限がある位置に空調装置12が配置されていても、上記の風向調整装置10により風向を適切に調整できる。 Even if the air conditioner 12 is arranged at a position where it is difficult to take space and the layout is limited, such as a side portion of a vehicle compartment of the vehicle, the wind direction adjusting device 10 can appropriately adjust the wind direction.

なお、上記の第1の実施の形態において、図9及び図10に示す第2の実施の形態のように、フィニッシャ15の吹出口31をハウジング21の遮蔽部49の前方の位置まで拡張して開口させても、同様の作用効果を奏することができる。 In the first embodiment described above, as in the second embodiment shown in FIGS. 9 and 10, the outlet 31 of the finisher 15 is expanded to a position in front of the shielding portion 49 of the housing 21. Even if it is opened, the same effect can be obtained.

また、遮蔽部49は、ハウジング21に代えて、フィニッシャ15に設けてもよい。 Further, the shielding portion 49 may be provided on the finisher 15 instead of the housing 21.

さらに、縦ルーバ16には、遮蔽部49の背面に位置する非露出縦ルーバ16aが設定されていなくてもよい。つまり、ダクト11の一部を延長して閉じ通路58を構成し、縦ルーバ16は吹出口31に対向する位置にのみ配置されているように構成されていてもよい。 Further, the vertical louver 16 does not need to have the non-exposed vertical louver 16a located on the back surface of the shield 49. That is, a part of the duct 11 may be extended to form the closed passage 58, and the vertical louver 16 may be arranged only at a position facing the outlet 31.

また、上記の各実施の形態において、空調装置12は、車両用のものだけでなく、任意の空調装置として用いることができる。 Further, in each of the above-described embodiments, the air conditioner 12 can be used not only for a vehicle but also as an arbitrary air conditioner.

本発明は、例えば、自動車の車室側部や天井などに備えられる車両用空調装置の風向調整装置として適用できる。 INDUSTRIAL APPLICABILITY The present invention can be applied, for example, as a wind direction adjusting device for a vehicle air conditioner provided on a vehicle compartment side or a ceiling of an automobile.
