Description

本発明は、車両の空調装置に関する。 The present invention relates to a vehicle air conditioner.

3列シートを有する車両などの車室前後長が長い車両の空調装置においては、例えば特許文献1に示されているように、車室前部のインストルメントパネルなどに設けられる前部吹き出し口に加え、天井内面に車室後方へ向けた天井吹き出し口が設けられることがある。 In an air conditioner for a vehicle having a long front-rear length in the passenger compartment, such as a vehicle having three rows of seats, for example, as shown in Patent Document 1, the front outlet provided on an instrument panel at the front of the passenger compartment is provided. In addition, a ceiling outlet facing the rear of the passenger compartment may be provided on the inner surface of the ceiling.

天井吹き出し口からの空気流を天井内面に沿った比較的流速のあるものとすることにより、前部吹き出し口からの空気流の一部を天井内面に引き寄せ、これを天井吹き出し口からの空気流で加速し、十分な空気流をコアンダ効果により天井内面に沿って車室後方空間に導くことができる。 By making the air flow from the ceiling outlet relatively flowable along the inner surface of the ceiling, a part of the air flow from the front outlet is drawn to the inner surface of the ceiling, and this is attracted to the air flow from the ceiling outlet. Accelerates with, and a sufficient air flow can be guided to the space behind the passenger compartment along the inner surface of the ceiling by the Coanda effect.

ところで、車室後部シートに着座する乗員に適切に空調された空気流を向かわせるためには、コアンダ効果により天井内面に沿って流れる空気流を天井内面から所望のように引き剥がすことが求められる。特許文献1に記載された空調装置においては、そのために天井吹き出し口よりも後方に、空気流れの方向を斜め下後方への方向に変更する可動フラップが設けられている。 By the way, in order to direct an appropriately air-conditioned air flow to an occupant seated in the rear seat of the passenger compartment, it is required to remove the air flow flowing along the inner surface of the ceiling from the inner surface of the ceiling as desired by the Coanda effect. .. In the air conditioner described in Patent Document 1, a movable flap that changes the direction of the air flow diagonally downward and rearward is provided behind the ceiling outlet for that purpose.

しかしながら、可動フラップを設けることはコスト上昇を招くし、可動フラップの方向を適切に調節することが前部シートに着座するドライバにとっても、後部シートに着座する乗員にとっても、必ずしも容易とはいえない。 However, providing a movable flap increases costs, and it is not always easy for the driver seated in the front seat and the occupant seated in the rear seat to properly adjust the direction of the movable flap. ..

本発明は、上記した事情のもとで考え出されたものであって、前部吹き出し口と天井吹き出し口とを有する車両の空調装置において、簡単な構成により、車室の後方空間への適切な空気流を形成できるようにすることをその課題とする。 The present invention has been conceived under the above circumstances, and is suitable for the rear space of a vehicle interior by a simple configuration in an air conditioner for a vehicle having a front outlet and a ceiling outlet. The challenge is to be able to form an air flow.

上記課題を解決するため、本発明では、次の技術的手段を採用した。 In order to solve the above problems, the following technical means are adopted in the present invention.

すなわち、本発明により提供される車両の空調装置は、車室前部に設置され、後方への空気流を形成する前部吹き出し口と、車室の天井に設置され、後方を向く天井吹き出し口と、を有する車両の空調装置において、上記天井吹き出し口の下方に近接して、斜め下後方に向けて所定量で突出する突起部を設けたことを特徴とする。 That is, the vehicle air conditioner provided by the present invention is installed in the front part of the vehicle interior and forms a rear air flow, and is installed in the ceiling of the vehicle interior and faces the rear. In the air conditioner of the vehicle having the

天井吹き出し口からの空気流は、前部吹き出し口が形成する空気流の一部を天井に引き寄せ、こうして引き寄せられた空気流が当該天井吹き出し口からの空気流と合流させられるとともに流速加速作用を受け、合流させられた空気流の必要量がコアンダ効果により天井に沿って車室後方に向かわせられる。 The air flow from the ceiling outlet attracts a part of the air flow formed by the front outlet to the ceiling, and the air flow thus attracted merges with the air flow from the ceiling outlet and accelerates the flow velocity. The required amount of air flow that has been received and merged is directed toward the rear of the passenger compartment along the ceiling by the Coanda effect.

天井吹き出し口の下方に近接して上記の突起部を設けるという簡単な構成により、上記合流させられた空気流の向きを車室後部に着座する乗員に向かうように適切に変更することができる。 With a simple configuration in which the above-mentioned protrusion is provided close to the lower part of the ceiling outlet, the direction of the combined air flow can be appropriately changed toward the occupant seated at the rear of the passenger compartment.

本発明のその他の特徴および利点は、図面を参照して以下に行う詳細な説明から、より明らかとなろう。 Other features and advantages of the invention will become more apparent from the detailed description given below with reference to the drawings.

図に示す実施形態は、車室前後方向に3列のシートを設置した車両1に本発明を適用した例である。 The embodiment shown in the figure is an example in which the present invention is applied to a vehicle 1 in which three rows of seats are installed in the front-rear direction of the passenger compartment.

図1に示すように、車室前方の例えばインストルメントパネル11には、空調装置2の前部吹き出し口21,22,23が設けられる。車室前部には、前部シートに着座する乗員に向けて空調された空気を吹き出すもの22や、前部シート31に着座する乗員の足元に向けて空調された空気を吹き出すもの21や、斜め上後方を向き、空気流を天井に沿って後方に向かわせるもの23が設けられる。 As shown in FIG. 1, for example, the instrument panel 11 in front of the passenger compartment is provided with front outlets 21, 22, 23 of the air conditioner 2. At the front of the passenger compartment, there are 22 that blow out air-conditioned air toward the occupants seated in the front seats 21, 21 that blow out air-conditioned air toward the feet of the occupants seated in the front seats 31, and so on. A device 23 is provided that faces diagonally upward and backward and directs the air flow to the rear along the ceiling.

車室の前後方向中間部の天井4には、天井吹き出し口24が設けられる。この天井吹き出し口24から吹き出される空気流は、空調された空気をダクトにより天井裏に導かれるものであってもよいが、本実施形態では、吸い込み口25から吸い込んだ空気を天井裏に設置した蒸発器やヒータ(図示略)により冷却または加熱してファン(図示略)により吹き出す形態のものが採用されている。 A ceiling outlet 24 is provided on the ceiling 4 in the middle portion in the front-rear direction of the vehicle interior. The air flow blown out from the ceiling outlet 24 may be one in which the air-conditioned air is guided to the ceiling behind by a duct, but in the present embodiment, the air sucked from the suction port 25 is installed behind the ceiling. A form in which the air is cooled or heated by an air conditioner or a heater (not shown) and blown out by a fan (not shown) is adopted.

図2に示すように、本実施形態では、天井4の車幅方向中央部に吸い込み口25が設置され、天井吹き出し口24は吸い込み口25を車幅方向に挟む2か所に設けられている。また、天井吹き出し口24はその開口上下幅が薄い横長状になっており、天井4に沿うような恰好で比較的速い流速の空気流を吹き出すことができるように形成されている。 As shown in FIG. 2, in the present embodiment, the suction port 25 is installed at the center of the ceiling 4 in the vehicle width direction, and the ceiling outlet 24 is provided at two places sandwiching the suction port 25 in the vehicle width direction. .. Further, the ceiling outlet 24 has a horizontally long shape in which the vertical width of the opening is thin, and is formed so as to be able to blow out an air flow having a relatively high flow velocity, which is suitable along the ceiling 4.

図3は、天井吹き出し口24を含む天井4の縦断面(図2のIII-III線断面)を示す。 FIG. 3 shows a vertical cross section of the ceiling 4 including the ceiling outlet 24 (cross section taken along line III-III in FIG. 2).

天井4の裏側に形成されたスペースに閉断面状の空気流路26が形成されており、この空気流路26から、天井吹き出し口24を形成するためのノズル部27が斜め下後方に向けて延ばされている。このノズル部27は、横長状の閉断面を有しており、その後端部開口が天井吹き出し口24を形成している。空調され、図示しないファンにより流速を与えられた空気は、空気流路26およびノズル部27を通って天井吹き出し口24から吹き出されることになる。 An air flow path 26 having a closed cross section is formed in a space formed on the back side of the ceiling 4, and a nozzle portion 27 for forming the ceiling outlet 24 is directed diagonally downward and rearward from the air flow path 26. It has been postponed. The nozzle portion 27 has a horizontally long closed cross section, and the rear end opening forms the ceiling outlet 24. The air that has been air-conditioned and given a flow velocity by a fan (not shown) will be blown out from the ceiling outlet 24 through the air flow path 26 and the nozzle portion 27.

ノズル部261の内部には、吹き出し口24からの空気流の方向を左右方向に変更することができるフィン28が設けられている。フィン28は、その下部からノズル部27の下壁271を貫通して延びる軸29を中心として回動可能である。軸29には、その下部から軸29と直角方向後方に向けて一体的に延びる操作部281が設けられており、操作部281は、ノズル部27が延びる方向と平行な、斜め下後方に延びることになる。操作部281は、本実施形態において、軸29を中心とする孤状の縁282を有する扇形をしている。フィン28は、この操作部281を操作することにより、方向を変更することができる。 Inside the nozzle portion 261, fins 28 that can change the direction of the air flow from the outlet 24 in the left-right direction are provided. The fin 28 is rotatable about a shaft 29 extending from the lower portion thereof through the lower wall 271 of the nozzle portion 27. The shaft 29 is provided with an operation unit 281 that extends integrally from the lower portion toward the rear in a direction perpendicular to the shaft 29, and the operation unit 281 extends diagonally downward and rearward in parallel with the direction in which the nozzle portion 27 extends. It will be. In the present embodiment, the operation unit 281 has a fan shape having an isolated edge 282 centered on the shaft 29. The fin 28 can change the direction by operating the operation unit 281.

上記操作部281は、天井吹き出し口24の下方を覆うガーニッシュ5の後端部51から、適当距離突出させられており、本実施形態では、上記操作部281のガーニッシュ5から突出する部分が、本発明の突起部6に相当する。 The operation unit 281 is projected from the rear end portion 51 of the garnish 5 covering the lower part of the ceiling outlet 24 by an appropriate distance. In the present embodiment, the portion of the operation unit 281 projecting from the garnish 5 is the present. Corresponds to the protrusion 6 of the invention.

図3に表れているように、上記ノズル部27の下方を覆うガーニッシュ5の下面52、並びに、ガーニッシュ5および当該ガーニッシュ5の前方の天井面41は、その延長線が天井吹き出し口24の後方の天井面42にいたるようにして、なだらかに湾曲している。 As shown in FIG. 3, the lower surface 52 of the garnish 5 that covers the lower part of the nozzle portion 27, and the ceiling surface 41 in front of the garnish 5 and the garnish 5 have an extension line behind the ceiling outlet 24. It is gently curved so as to reach the ceiling surface 42.

次に、上記構成の車両の空調装置2の作用について説明する。 Next, the operation of the air conditioner 2 of the vehicle having the above configuration will be described.

後方に向かわせられた前部吹き出し口22や前部吹き出し口23からの空気流FL1は、天井吹き出し口24から比較的高速で吹き出される空気流FL2に引き寄せられて当該空気流FL2に合流させられた空気流FL3となる。上記したように、ガーニッシュ5および天井面41,42がなだらかに湾曲しておりために、上記合流させられた空気流FL3の必要量がコアンダ効果により天井4に沿ってさらに車室後方に向かわせられる。 The air flow FL1 from the front outlet 22 and the front outlet 23 directed to the rear is attracted to the air flow FL2 blown out from the ceiling outlet 24 at a relatively high speed and merges with the air flow FL2. The air flow is FL3. As described above, since the garnish 5 and the ceiling surfaces 41 and 42 are gently curved, the required amount of the combined air flow FL3 is further directed to the rear of the passenger compartment along the ceiling 4 by the Coanda effect. Be done.

一方、天井吹き出し口24の下方において、ガーニッシュ5の後端からの突起部6を形成するフィン28の操作部281が設けられているために、上記合流させられた空気流FL3の一部(FL3’)を、シート32に着座する乗員にも向かうように適切に変更することができる。 On the other hand, since the operation portion 281 of the fin 28 forming the protrusion 6 from the rear end of the garnish 5 is provided below the ceiling outlet 24, a part of the combined air flow FL3 (FL3). ') Can be appropriately changed so that it also faces the occupant seated in the seat 32.

本実施形態では、天井吹き出し口24のフィン28の方向を変更するための操作部281に、上記したように合流させられた空気流FL3の一部(FL3’)の方向を変更する突起部6としての機能を与えているので、特別なフラップを設けることに比較し、違和感なく車室内環境をシンプルに整えることができる。 In the present embodiment, the protrusion 6 for changing the direction of a part (FL3') of the air flow FL3 merged as described above with the operation unit 281 for changing the direction of the fin 28 of the ceiling outlet 24. Compared to the provision of a special flap, it is possible to simply arrange the interior environment of the vehicle without any discomfort.
