Description

【０００１】
【発明の属する技術分野】
本発明は、車両用空調装置の送風空気吹き出し口の開閉機構に関する。
【０００２】
【従来の技術】
車両用空調装置の送風空気の前席吹き出し口であるベンチレーターは、車両のインストルメントパネル内の運転席窓側、運転席側中央、助手席側中央、助手席窓側の各箇所に設けられる。各ベンチレーターには、開閉機構がそれぞれ設けられている。
【０００３】
【発明が解決しようとする課題】
運転者のみが乗車している場合、助手席側中央、助手席窓側の各ベンチレーターを閉じて、運転席窓側、運転席側中央の各ベンチレーターからの風量を増やすことで、急冷時の清涼感を早く得ることができる。また乗員にとって車両内温度および湿度が快適であるときには、ファン回転数を抑えて送風ファンの省エネルギー運転ができる。停車中に助手席側にのみ乗車している場合にも、同様のことがいえる。
【０００４】
しかし従来の車両用空調装置では、各ベンチレーターを開閉するためには、各ベンチレーターに設けられているそれぞれの開閉機構に手を伸ばして開閉をしなくてはならない。運転席から最も遠い助手席窓側ベンチレーターを開閉するためには、運転者は助手席側へ大きく身を乗りだして手を伸ばさなければならない。また、助手席側から運転席窓側ベンチレーターの開閉操作を行おうとしても、運転席窓側ベンチレーターがハンドルなどの運転操作装置の陰に位置しているため、実際には開閉操作ができない。
【０００５】
本発明は、簡単な機構で、乗員が乗車席から大きく身を乗りだして手を伸ばすことなく、ドア側吹き出し口からの送風空気量を調整することができる車両用空調装置を提供することにある。

【０００７】
【発明の効果】
本発明によれば、乗員が乗車席から大きく身を乗りだして手を伸ばすことなく、車両ドア近傍に設けられた吹き出し口からの送風空気量を調整することができる。
【０００８】
【発明の実施の形態】
図１〜５を用いて、本発明による車両用空調装置の一実施の形態を説明する。図１は、一実施の形態の車両用空調装置を搭載した右ハンドル車を車両斜め後方から見た斜視図である。一実施の形態の車両用空調装置は、空調ユニット１００と、各ダクト１２，２２，３２，４２とがインストルメントパネル２００の内側に設けられている。インストルメントパネル２００には、助手席窓側の吹き出し口である第１ベンチレーター１０と、助手席側中央の吹き出し口である第２ベンチレーター２０と、運転席側中央の吹き出し口である第３ベンチレーター３０と、運転席窓側の吹き出し口である第４ベンチレーター４０とが設けられている。空調ユニット１００の内部には、不図示の送風機と、送風機から送風される空気を除湿および冷却をする不図示のエバポレータと、ヒータコアへの配風比を調節する不図示のエアミックスドアと、エバポレータで除湿および冷却された送風空気を再加熱する不図示のヒータコアとが設けられている。空調ユニット１００のヒータコア下流側には第１送風経路１〜第４送風経路４の４つの送風経路が備えられている。不図示の送風機から送風された送風空気は、不図示のエバポレータおよびヒータコアを通過し、各送風経路１〜４より各ダクト１２，２２，３２，４２を通って各ベンチレーター１０，２０，３０，４０から車両室内に吹き出す。
【０００９】
助手席窓側の第１ベンチレーター１０には第１ベンチレーターダクト１２（以下、第１ダクト１２と呼ぶ）が接続されており、第１ダクト１２には第１送風経路１が接続されている。同様に助手席側中央の第２ベンチレーター２０には第２ベンチレーターダクト２２（以下、第２ダクト２２と呼ぶ）が接続されており、第２ダクト２２には第２送風経路２が接続されている。運転席側中央の第３ベンチレーター３０には第３ベンチレーターダクト３２（以下、第３ダクト３２と呼ぶ）が接続されており、第３ダクト３２には第３送風経路３が接続されている。運転席ドア側の第４ベンチレーター４０には第４ベンチレーターダクト４２（以下、第４ダクト４２と呼ぶ）が接続されており、第４ダクト４２には第４送風経路４が接続されている。
【００１０】
図２を参照して各送風経路１〜４について説明する。各送風経路１〜４には、それぞれ第１送風経路１の開閉ドア１５（以下、第１開閉ドア１５と呼ぶ）、第２送風経路２の開閉ドア２５（以下、第２開閉ドア２５と呼ぶ）、第３送風経路３の開閉ドア３５（以下、第３開閉ドア３５と呼ぶ）、第４送風経路４の開閉ドア４５（以下、第４開閉ドア４５と呼ぶ）が備えられている。各開閉ドア１５，２５，３５，４５は、回動軸１５Ｘ，２５Ｘ，３５Ｘ，４５Ｘを中心に各送風経路１〜４内で回動することにより、各ベンチレーターダクト１２，２２，３２，４２へ接続されている各送風経路１〜４を開閉する。各回動軸１５Ｘ，２５Ｘ，３５Ｘ，４５Ｘには、溝部を有するアーム１６，２６，３６，４６が一体に回動するように取り付けられている。すなわち、第１回動軸１５Ｘには第１アーム１６が、第２回動軸２５Ｘには第２アーム２６が、第３回動軸３５Ｘには第３アーム３６が、第４回動軸４５Ｘには第４アーム４６がそれぞれ一体に回動するように取り付けられている。
【００１１】
４カ所のベンチレーターのうち、助手席側中央の第２ベンチレーター２０および運転席側中央の第３ベンチレーター３０には、助手席側ベンチレーター開閉ダイヤル２３（以下、開閉ダイヤル２３と呼ぶ）および運転席側ベンチレーター開閉ダイヤル３３がそれぞれ備えられている。以下の説明では、助手席側の各ベンチレーター１０，２０について説明を行うが、運転席側の各ベンチレーター３０，４０についても同様であるので詳細な説明は省略する。
【００１２】
図３および図４を参照して、開閉ダイヤル２３の操作力を第１および第２開閉ドア１５，２５に伝達する機構について詳細に説明する。開閉ダイヤル２３には、助手席側ベンチレーター開閉ワイヤー２４（以下、開閉ワイヤー２４と呼ぶ）の一端が接続されている。開閉ワイヤー２４の他端は、助手席側ベンチレーター開閉レバー２７（以下、開閉レバー２７と呼ぶ）の第２ピン２７２近傍に接続されている。開閉レバー２７の両端には、それぞれ第１ピン２７１，第２ピン２７２が配設されており、この各ピン２７１，２７２が各回動軸１５Ｘ，２５Ｘに接続された各アーム１６，２６の溝１６１，２６１内に摺動可能に挿入されている。すなわち第１ピン２７１は第１アーム１６の第１溝部１６１へ、第２ピン２７２は第２アーム２６の第２溝部２６１へ摺動可能に挿入されている。乗員が開閉ダイヤル２３を操作することにより、開閉ダイヤル２３の動きが開閉ワイヤー２４を介して開閉レバー２７に伝えられ、この開閉レバー２７から伝達された動きが各アーム１６，２６を動かし、各開閉ドア１５，２５を開閉する。また、開閉レバー２７は、不図示のバネによって時計方向に回転する力があらかじめ掛けられている。
【００１３】
図３は、第１開閉ドア１５および第２開閉ドア２５がどちらも開の状態を表している。この図３の状態から開閉ダイヤル２３がその回動中心２３Ｘの回りを時計方向に回転されると、開閉ワイヤー２４の一端が開閉ダイヤル２３に引っ張られることで、開閉ワイヤー２４の他端が開閉レバー２７を不図示のバネの力に逆らって反時計方向に回動させる。
【００１４】
開閉レバー２７の両端に設けられている各ピン２７１，２７２は、開閉レバー２７の回動とともに、開閉レバー２７の回動中心を回動する。このとき各ピン２７１，２７２は、第１アーム１６および第２アーム２６に設けられた各溝部１６１，２６１を摺動する。よって、開閉レバー２７が回動軸２７Ｘの回りを回動することで、第１アーム１６および第２アーム２６は、移動した各ピン２７１，２７２の位置と第１アーム１６および第２アーム２６に設けられた溝部１６１，２６１の形状とによって定まる角度に、回動軸１５Ｘ，２５Ｘを中心として回動する。上述したように、第１アーム１６と第１開閉ドアの回動軸１５Ｘ、および第２アーム２６と第２開閉ドアの回動軸２５Ｘはそれぞれ一体に回動するように固定されているので、開閉ダイヤル２３を回転させると、第１開閉ドア１５および第２開閉ドア２５は、各ピン２７１，２７２の位置と各溝部１６１，２６１の形状とによって定まる角度に回動する。
【００１５】
第１開閉ドア１５および第２開閉ドア２５がどちらも開である図３に示した状態から、開閉ダイヤル２３を回動軸２３Ｘの回りを略４５度時計方向に回転させると、図４に示す状態となる。開閉ダイヤル２３の操作によって開閉レバー２７は反時計方向に略４５度回動する。このときピン２７１と溝部１６１との関係から、アーム１６は回動軸１５Ｘとともに回動軸１５Ｘの回りを時計方向に略４５度回動するので、開閉ドア１５も回動軸１５Ｘに対して時計方向に略４５度回動して送風経路１を閉じる。同時に、ピン２７２も開閉レバー２７の回動軸２７Ｘに対して反時計方向に略４５度回動するが、ピン２７２と溝部２６１との関係から、アーム２６は動かない。
【００１６】
第１開閉ドア１５が閉で、第２開閉ドア２５が開である図４に示した状態から、さらに開閉ダイヤル２３を回動軸２３Ｘの回りを略４５度時計方向に回転させると、図５に示す状態となる。開閉ダイヤル２３の操作によって開閉レバー２７は反時計方向に略４５度回動する。このときピン２７１と溝部１６１との関係から、アーム１６は動かない。同時に、ピン２７２も開閉レバー２７の回動軸２７Ｘに対して反時計方向に略４５度回動し、ピン２７２と溝部２６１との関係から、アーム２６は回動軸２５Ｘとともに回動軸２５Ｘに対して時計方向に略４５度回動するので、開閉ドア２５も回動軸２５Ｘに対して時計方向に略４５度回動して送風経路２を閉じる。
【００１７】
第１開閉ドア１５および第２開閉ドア２５がともに閉である図５に示した状態から、開閉ダイヤル２３を回動軸２３Ｘの回りを略４５度反時計方向に回転させると、上述した動作とは逆に第１開閉ドア１５および第２開閉ドア２５が開となる。すなわち、図５に示した状態から、開閉ダイヤル２３を回動軸２３Ｘの回りを略４５度反時計方向に回転させると、開閉レバー２７に設けた不図示のバネの力により、最初に第２開閉ドア２５が開となり、次に第１開閉ドア１５が開になる。
【００１８】
運転席側の各ベンチレーター３０，４０も助手席側の各ベンチレーター１０，２０と同様の構造である。
【００１９】
上記構成の車両用空調装置では、次のような作用効果を奏することができる。
（１）インストルメントパネル２００の車両幅方向に対して中央付近に設けたベンチレータ開閉ダイヤル２３により、窓側のベンチレータ１０への送風空気量と、インストルメントパネル２００の中央付近に設けたベンチレータ２０への送風空気量とを調整する構造としたので、簡単な機構で、乗員が乗車席から大きく身を乗りだして手を伸ばすことなく、窓側のベンチレータ１０への送風空気量を調整することができる。
（２）助手席側ベンチレーター開閉ダイヤル２３の操作で、助手席側の２箇所のベンチレーター１０，２０へ送風する各送風経路１，２に設けられた各開閉ドア１５，２５が開閉できる構造とした。これにより、運転者のみが乗車している場合、助手席窓側ベンチレーター１０、もしくは助手席窓側および助手席側中央の各ベンチレーター１０，２０を閉じて、運転席側中央、運転席窓側の各ベンチレーター３０，４０からの風量を増やすことができ、急冷時の清涼感を早く得ることができる。乗員にとって車両内温度および湿度が快適であるときには、ファン回転数を抑えて送風ファンの省エネルギー運転ができる。また、開閉ダイヤルの開度の確認も容易である。運転席側の各ベンチレーター３０，４０についても助手席側の各ベンチレーター１０，２０と同様である。
（３）空調ユニット１００内の車両室内に最も近いところに各送風経路１〜４を設けて、各送風経路１〜４内に各開閉ドア１５，２５，３５，４５を配設した。これにより車両窓側に配設された各ベンチレーター１０、４０の開閉機構をインストルメントパネル２００中央側に配設されたベンチレーター開閉ダイヤルで操作するためのワイヤーやリンクなどの機構の配設距離が短くて済むため、設計、配設が容易でコストも低い。
【００２０】
上述の一実施の形態の車両用空調装置では、ベンチレーターの開閉機構は、ワイヤーによるリンク機構として説明したが、これに限定されない。また、ベンチレーターの開閉機構を手動で行っているが、電動式としてもよい。さらに、本発明の特徴的な機能を損なわない限り、本発明は、上述した実施の形態に何ら限定されない。
【００２１】
以上の実施の形態およびその変形例において、操作部は、助手席側ベンチレーター開閉ダイヤル２３および運転席側ベンチレーター開閉ダイヤル３３に対応する。調整機構は、助手席側については、開閉ダイヤル２３、開閉ワイヤー２４、開閉レバー２７、各アーム１６，２６および各開閉ドア１５，２５により構成される。運転席側の調整機構についても同様である。

One end of a passenger seat side ventilator opening / closing wire 24 (hereinafter referred to as opening / closing wire 24) is connected to the opening / closing dial 23. The other end of the opening / closing wire 24 is connected to the vicinity of the second pin 272 of the passenger seat side ventilator opening / closing lever 27 (hereinafter referred to as the opening / closing lever 27). A first pin 271 and a second pin 272 are disposed at both ends of the opening / closing lever 27, and the pins 161 and 272 are grooves 161 of the arms 16 and 26 connected to the rotary shafts 15X and 25X, respectively. , 261 is slidably inserted. That is, the first pin 271 is slidably inserted into the first groove 161 of the first arm 16 and the second pin 272 is slidably inserted into the second groove 261 of the second arm 26. When the occupant operates the open / close dial 23, the movement of the open / close dial 23 is transmitted to the open / close lever 27 via the open / close wire 24, and the movement transmitted from the open / close lever 27 moves the arms 16 and 26 to The doors 15 and 25 are opened and closed. The opening / closing lever 27 is preliminarily applied with a force that rotates clockwise by a spring (not shown).
[0013]
FIG. 3 shows a state where both the first opening / closing door 15 and the second opening / closing door 25 are open. When the open / close dial 23 is rotated clockwise around the rotation center 23X from the state shown in FIG. 3, one end of the open / close wire 24 is pulled by the open / close dial 23 so that the other end of the open / close wire 24 is connected to the open / close lever. 27 is rotated counterclockwise against the force of a spring (not shown).
[0014]
The pins 271 and 272 provided at both ends of the opening / closing lever 27 rotate around the rotation center of the opening / closing lever 27 as the opening / closing lever 27 rotates. At this time, the pins 271 and 272 slide in the groove portions 161 and 261 provided in the first arm 16 and the second arm 26, respectively. Therefore, when the opening / closing lever 27 rotates around the rotation shaft 27 </ b> X, the first arm 16 and the second arm 26 are moved to the positions of the moved pins 271 and 272 and the first arm 16 and the second arm 26. It rotates around the rotation shafts 15X and 25X at an angle determined by the shape of the provided grooves 161 and 261. As described above, the rotation shaft 15X of the first arm 16 and the first opening / closing door and the rotation shaft 25X of the second arm 26 and the second opening / closing door are fixed so as to rotate together, respectively. When the opening / closing dial 23 is rotated, the first opening / closing door 15 and the second opening / closing door 25 are rotated at an angle determined by the positions of the pins 271, 272 and the shapes of the grooves 161, 261.
[0015]
When the first open / close door 15 and the second open / close door 25 are both open, the open / close dial 23 is rotated approximately 45 degrees clockwise about the rotation shaft 23X as shown in FIG. It becomes a state. By operating the open / close dial 23, the open / close lever 27 is rotated approximately 45 degrees counterclockwise. At this time, because of the relationship between the pin 271 and the groove 161, the arm 16 rotates about 45 degrees clockwise around the rotation axis 15X together with the rotation axis 15X. The air passage 1 is closed by rotating about 45 degrees in the direction. At the same time, the pin 272 also rotates approximately 45 degrees counterclockwise with respect to the rotation shaft 27X of the opening / closing lever 27, but the arm 26 does not move due to the relationship between the pin 272 and the groove 261.
[0016]
When the first opening / closing door 15 is closed and the second opening / closing door 25 is open, the opening / closing dial 23 is further rotated about 45 degrees clockwise about the rotation shaft 23X, as shown in FIG. It will be in the state shown in By operating the open / close dial 23, the open / close lever 27 is rotated approximately 45 degrees counterclockwise. At this time, the arm 16 does not move due to the relationship between the pin 271 and the groove 161. At the same time, the pin 272 is also rotated approximately 45 degrees counterclockwise with respect to the rotation shaft 27X of the opening / closing lever 27, and the arm 26 is moved together with the rotation shaft 25X to the rotation shaft 25X due to the relationship between the pin 272 and the groove 261. On the other hand, since it rotates approximately 45 degrees in the clockwise direction, the open / close door 25 also rotates approximately 45 degrees in the clockwise direction with respect to the rotation shaft 25X to close the blower path 2.
[0017]
When the first open / close door 15 and the second open / close door 25 are both closed and the open / close dial 23 is rotated approximately 45 degrees counterclockwise about the rotation shaft 23X from the state shown in FIG. Conversely, the first opening / closing door 15 and the second opening / closing door 25 are opened. That is, from the state shown in FIG. 5, when the open / close dial 23 is rotated approximately 45 degrees counterclockwise around the rotation shaft 23X, the second force is first applied by the force of a spring (not shown) provided on the open / close lever 27. The opening / closing door 25 is opened, and then the first opening / closing door 15 is opened.
[0018]
The ventilators 30 and 40 on the driver seat side have the same structure as the ventilators 10 and 20 on the passenger seat side.
[0019]
The vehicle air conditioner having the above configuration can provide the following operational effects.
(1) By the ventilator opening / closing dial 23 provided near the center of the instrument panel 200 in the vehicle width direction, the amount of air blown to the ventilator 10 on the window side and the ventilator 20 provided near the center of the instrument panel 200 Since the structure adjusts the amount of blown air, the amount of blown air to the window-side ventilator 10 can be adjusted with a simple mechanism without the passenger getting out of the passenger seat and reaching out.
(2) By opening / closing the front ventilator opening / closing dial 23 on the passenger seat side, the open / close doors 15 and 25 provided in the air passages 1 and 2 for blowing air to the two ventilators 10 and 20 on the passenger seat side can be opened and closed. . Thus, when only the driver is on board, the passenger seat window side ventilator 10 or the ventilators 10 and 20 at the passenger seat window side and the passenger seat side center are closed, and the ventilators 30 at the driver side center and the driver seat window side are closed. , 40 can be increased, and a refreshing feeling during rapid cooling can be obtained quickly. When the in-vehicle temperature and humidity are comfortable for the occupant, the fan rotation speed can be suppressed and energy saving operation of the blower fan can be performed. It is also easy to check the opening of the open / close dial. The ventilators 30 and 40 on the driver seat side are the same as the ventilators 10 and 20 on the passenger seat side.
(3) The ventilation paths 1 to 4 are provided in the air conditioning unit 100 closest to the vehicle compartment, and the open / close doors 15, 25, 35, and 45 are disposed in the ventilation paths 1 to 4. As a result, the disposition distance of mechanisms such as wires and links for operating the opening and closing mechanisms of the ventilators 10 and 40 disposed on the vehicle window side with the ventilator opening and closing dial disposed on the center side of the instrument panel 200 is short. Therefore, the design and arrangement are easy and the cost is low.
