このケース１１内の上流側部位には、空気流を発生する送風手段としての第１ファン１２および第２ファン１３が設けられている。本例では、第１、第２ファン１２、１３は同軸上に配置され、共通のモータ（図示せず）にて回転駆動される。   A first fan 12 and a second fan 13 are provided in the upstream portion of the case 11 as air blowing means for generating an air flow. In this example, the 1st, 2nd fans 12 and 13 are arrange | positioned coaxially, and are rotationally driven by a common motor (not shown).

図示を省略しているが、ケース１１のうち両ファン１２、１３の上流側には、内気モード、外気モードおよび内外気２層モードの３つのモードに応じて、両ファン１２、１３の吸込み空気を車室内の空気（内気）および車室外の空気（外気）のいずれかに切り替える内外気切替装置が配置されている。   Although not shown, on the upstream side of the fans 12 and 13 in the case 11, the intake air of the fans 12 and 13 is in accordance with the three modes of the inside air mode, the outside air mode, and the inside and outside air two-layer mode. An inside / outside air switching device for switching between the air in the passenger compartment (inside air) and the air outside the passenger compartment (outside air) is disposed.

具体的には、内外気切替装置には、内気を導入する内気導入口と、外気を導入する外気導入口とが形成されている。この内気導入口および外気導入口は、内外気切替ドアにより切替開閉されるようになっている。   Specifically, the inside / outside air switching device is formed with an inside air introduction port for introducing inside air and an outside air introduction port for introducing outside air. The inside air introduction port and the outside air introduction port are opened and closed by an inside / outside air switching door.

内外気切替装置は、内気モードが選択されると両ファン１２、１３の吸込み空気を内気にする。内外気切替装置は、外気モードが選択されると両ファン１２、１３の吸込み空気を外気にする。そして、内外気切替装置は、内外気２層モードが選択されると、第１ファン１２の吸込み空気を内気にし、第２ファン１３の吸込み空気を外気にする。   When the inside air mode is selected, the inside / outside air switching device turns the intake air of both fans 12 and 13 into the inside air. When the outside air mode is selected, the inside / outside air switching device turns the intake air of both fans 12 and 13 into the outside air. When the inside / outside air two-layer mode is selected, the inside / outside air switching device turns the suction air of the first fan 12 into the inside air and turns the suction air of the second fan 13 into the outside air.

ケース１１内の空間は、第１ファン１２からの送風空気が流れる第１の空気通路１５と、第２ファン１３からの送風空気が流れる第２の空気通路１６とに、平板状の仕切部１４によって仕切られている。   The space in the case 11 is divided into a flat partition 14 by a first air passage 15 through which the blown air from the first fan 12 flows and a second air passage 16 through which the blown air from the second fan 13 flows. It is partitioned by.

仕切部１４は、ケース１１と同様の理由により、ポリプロピレン等の樹脂にて成形されており、その全体がケース１１に固定されている。具体的には、仕切部１４は、ケース１１を構成する複数の分割ケースと一体成形されている。なお、仕切部１４をケース１１と別体に成形した後に、ねじ止め等の適宜固定手段によってケース１１に固定してもよい。   The partition portion 14 is formed of a resin such as polypropylene for the same reason as the case 11, and the whole is fixed to the case 11. Specifically, the partition 14 is integrally formed with a plurality of divided cases constituting the case 11. In addition, after shape | molding the partition part 14 separately from the case 11, you may fix to the case 11 by appropriate fixing means, such as screwing.

仕切部１４は、後述するフィルタ部材１７、蒸発器１８およびヒータコアを第１、第２空気通路１５、１６に跨って配置するために、フィルタ部材１７、蒸発器１８およびヒータコアの配置領域を避けて形成されている。   The partition portion 14 avoids a region where the filter member 17, the evaporator 18 and the heater core are disposed in order to dispose the filter member 17, the evaporator 18 and the heater core which will be described later over the first and second air passages 15 and 16. Is formed.

ケース１１内において、第１ファン１２、第２ファン１３の下流側には、上記内気吸入口と上記外気吸入口とから吸入された空気を浄化するフィルタ部材１７が、第１、第２空気通路１５、１６に跨って配置されている。フィルタ部材１７は、一片が１５〜３０ｃｍ程度の四角形状を有しており、ケース１１内のほぼ全断面にわたって配置されている。   In the case 11, on the downstream side of the first fan 12 and the second fan 13, a filter member 17 that purifies the air sucked from the inside air inlet and the outside air inlet is the first and second air passages. 15 and 16 are arranged. The filter member 17 has a quadrangular shape with a piece of about 15 to 30 cm, and is disposed over almost the entire cross section in the case 11.

ケース１１のうちフィルタ部材１７の側方部位には、フィルタ部材１７を脱着するための脱着口１１ａが形成されている。図示の都合上、図１では、脱着口１１ａを二点鎖線で示している。   An attachment / detachment port 11 a for attaching / detaching the filter member 17 is formed in a side portion of the case 11 in the case 11. For convenience of illustration, in FIG. 1, the desorption port 11a is indicated by a two-dot chain line.

ケース１１は、脱着口１１ａを閉塞するカバー１１ｂを有している。カバー１１ｂは、ねじ、クリップ、係合爪等の適宜固定手段によりケース１１の脱着口１１ａ近傍部分に固定されている。   The case 11 has a cover 11b that closes the attachment / detachment port 11a. The cover 11b is fixed to the vicinity of the attachment / detachment port 11a of the case 11 by appropriate fixing means such as screws, clips, and engaging claws.

カバー１１ｂをケース１１の脱着口１１ａ部分から取り外すことにより、フィルタ部材１７をケース１１に対して仕切部１４と略平行な方向（図１の紙面垂直方向、図２の左右方向）に脱着することが可能になる。   By removing the cover 11b from the attachment / detachment opening 11a portion of the case 11, the filter member 17 is attached to and detached from the case 11 in a direction substantially parallel to the partition portion 14 (perpendicular to the plane of FIG. 1, left and right in FIG. 2). Is possible.

ケース１１内において、フィルタ部材１７の直ぐ下流側には、冷却用熱交換器としての蒸発器１８が、第１、第２空気通路１５、１６に跨って設けられている。蒸発器１８は、図示しない圧縮機、放熱器および膨張弁等とともに冷凍サイクルを構成している。   In the case 11, an evaporator 18 as a cooling heat exchanger is provided across the first and second air passages 15 and 16 immediately downstream of the filter member 17. The evaporator 18 constitutes a refrigeration cycle together with a compressor, a radiator, an expansion valve, and the like (not shown).

図示を省略しているが、ケース１１内において、蒸発器１８の下流側には加熱用熱交換器としてのヒータコアが、第１、第２空気通路１５、１６に跨って配置されている。図示を省略しているが、ケース１１内には、温度調整手段としてのエアミックスドアが配置されている。   Although not shown, in the case 11, a heater core as a heat exchanger for heating is disposed across the first and second air passages 15 and 16 on the downstream side of the evaporator 18. Although not shown, an air mix door as a temperature adjusting means is disposed in the case 11.

エアミックスドアは、その開度を連続的に変化させることによって、蒸発器１８にて冷却された冷風のうち、ヒータコアを通過させる風量とヒータコアをバイパスさせる風量との風量比を連続的に変化させて、車室内送風空気の温度を調整する。   The air mix door continuously changes the air flow ratio of the air volume that passes through the heater core and the air volume that bypasses the heater core among the cold air cooled by the evaporator 18 by continuously changing the opening degree. Adjust the temperature of the air blown into the passenger compartment.

図示を省略しているが、ケース１１の最下流部には、フェイス開口部、フット開口部およびデフロスタ開口部が形成されている。ケース１１内で温度調整された空調風は、これらの開口部から図示しないダクトに流入した後に、車室内に設けられたフェイス吹出口、フット吹出口およびデフロスタ吹出口（いずれも図示せず）から車室内に吹き出される。これらの開口部は、ケース１１内に配置された吹出モード切替ドア（図示せず）により切替開閉される。   Although not shown, a face opening, a foot opening, and a defroster opening are formed in the most downstream portion of the case 11. The conditioned air whose temperature has been adjusted in the case 11 flows into a duct (not shown) from these openings, and then from a face outlet, a foot outlet, and a defroster outlet (all not shown) provided in the passenger compartment. It is blown out into the passenger compartment. These openings are opened and closed by a blow mode switching door (not shown) disposed in the case 11.

上述した内気モード、外気モードおよび内外気２層モードの３つのモードのうち内外気２層モードでは、第１空気通路１５を流れた内気をフット吹出口から車室内足元部に向けて吹き出すとともに、第２空気通路１６を流れた外気をデフロスタ吹出口から窓ガラスに向けて吹き出す。これにより、車室内乗員足元部の暖房効果の向上と、窓ガラス防曇性の確保とを両立させる。   Among the three modes of the inside air mode, the outside air mode, and the inside / outside air two-layer mode described above, in the inside / outside air two-layer mode, the inside air that has flowed through the first air passage 15 is blown out from the foot blower outlet toward the vehicle interior foot, The outside air that has flowed through the second air passage 16 is blown out from the defroster outlet toward the window glass. Thereby, the improvement of the heating effect of a passenger | crew passenger | crew's foot part and ensuring of window-glass anti-fog property are made to make compatible.

そして、内外気２層モードにおいて、第１空気通路１５を流れる内気と第２空気通路１６を流れた外気とがフィルタ部材１７で混合してしまうことを防止するために、蒸発器１８上流側の仕切部１４をフィルタ部材１７の本体部１９内まで延長している。   In the inside / outside air two-layer mode, in order to prevent the inside air flowing through the first air passage 15 and the outside air flowing through the second air passage 16 from being mixed by the filter member 17, The partition 14 is extended into the main body 19 of the filter member 17.

ここで、フィルタ部材１７の構成を詳細に説明すると、本実施形態のフィルタ部材１７は、通過空気を浄化する本体部１９のみで構成されており、上記従来技術における枠体に相当するものを有していない。   Here, the configuration of the filter member 17 will be described in detail. The filter member 17 according to the present embodiment is composed only of the main body 19 that purifies the passing air, and has the one corresponding to the frame body in the above-described prior art. Not done.

本体部１９は、濾紙や不織布等の薄い濾材を襞状に折り曲げることで形成された四角形状の襞状部２０と、この襞状部２０の形状を保持するために襞状部２０の外周の全周にわたって接着された帯状の保持部２１とで構成されている。保持部２１は、不織布等により、襞状部２０よりも硬く形成されている。   The main body 19 includes a rectangular bowl-shaped portion 20 formed by bending a thin filter medium such as filter paper or nonwoven fabric into a bowl shape, and an outer periphery of the bowl-shaped portion 20 in order to maintain the shape of the bowl-shaped portion 20. It is comprised with the strip | belt-shaped holding | maintenance part 21 adhere | attached over the perimeter. The holding | maintenance part 21 is formed harder than the hook-shaped part 20 with the nonwoven fabric etc.
