Abstract

[Problem] To provide a vehicle air-conditioning device comprising flow guides with which it is possible to maintain a defrost function when a blend door is at a position near to a complete heating state, and to limit an increase in flow path resistance in a bypass path when the blend door is at a complete cooling state position. [Solution] Plate-shaped flow guides (40) that adjust the direction of air are provided in a connecting path (29) between a cooling heat exchanger (13) and the trajectory (L1) of a blend door (30) when the position of the blend door (30) changes. The flow guides (40) are at a distance from both a first wall surface (51) and a second wall surface (52). A downstream end (44) of each of the flow guides (40) is adjacent to or overlaps with the trajectory (L1). The flow guides (40) include a cooling air flow guide (41) installed so as to block air flowing toward a bypass path (28).

Description

車両用空調装置vehicle air conditioner
　本発明は、空気の流れを調整する整流ガイドを備えた車両用空調装置に関する。 The present invention relates to a vehicle air conditioner with a rectifying guide that adjusts the flow of air.
　乗用自動車等の車両の多くは、外気や内気を車室に取り込んで温度を調節（調和）するための、車両用空調装置を備えている。車両用空調装置に関する従来技術が特許文献１に開示されている。 Many vehicles such as passenger cars are equipped with a vehicle air conditioning system that draws outside and inside air into the cabin to adjust (harmonize) the temperature. Japanese Patent Laid-Open Publication No. 2002-300002 discloses a conventional technique related to a vehicle air conditioner.
　図１４は、特許文献１の図１を再掲して符号を振り直したものである。車両用空調装置９００は、外気や内気から取り込まれた空気が流れるケース９１０を備えている。ケース９１０には、取り込まれた空気を冷却可能な冷却用熱交換器９０１と、冷却用熱交換器９０１を通過した空気を加熱可能な加熱用熱交換器９０２と、が収納されている。 FIG. 14 is a reprint of FIG. 1 of Patent Document 1 with the reference numerals changed. A vehicle air conditioner 900 includes a case 910 through which air taken in from outside air or inside air flows. The case 910 accommodates a cooling heat exchanger 901 capable of cooling the taken air and a heating heat exchanger 902 capable of heating the air that has passed through the cooling heat exchanger 901 .
　ケース９１０の内部には、加熱用熱交換器９０２を通過した空気が流れる加熱路９１１と、加熱路９１１を迂回してエバポレータを通過した空気が流れるバイパス路９１２と、が設けられている。加熱路９１１の下流側とバイパス路９１２の下流側とは、エアミックス空間９１３に連通している。 A heating path 911 through which the air that has passed through the heating heat exchanger 902 flows, and a bypass path 912 that bypasses the heating path 911 and flows through the evaporator are provided inside the case 910 . The downstream side of the heating path 911 and the downstream side of the bypass path 912 communicate with the air mix space 913 .
　ケース９１０には、調和空気を吹き出すために開口している開口部９１４～９１６が形成されている。開口部９１４～９１６は、フロントガラスに向かって調和空気を送風しフロントガラス曇りを除去するデフロスタ開口部９１４と、前席の乗員の上半身に向かって調和空気を送風するベント開口部９１５と、前席の乗員の脚部に向かって調和空気を送風するフット開口部９１６と、を含んでいる。エアミックス空間９１３を通過した空気が調和空気となり、ケース９１０の開口部９１４～９１６から車両の室内に供給される。 A case 910 is formed with openings 914 to 916 that are open to blow out the conditioned air. Apertures 914-916 include a defroster opening 914 for blowing conditioned air toward the windshield to demist the windshield, a vent opening 915 for blowing the conditioned air toward the upper body of the front seat occupant, and a front and foot openings 916 for blowing conditioned air toward the legs of the seat occupant. The air that has passed through the air mix space 913 becomes conditioned air, and is supplied from the openings 914 to 916 of the case 910 into the interior of the vehicle.
　さらにケース９１０の内部には、バイパス路９１２を閉鎖する側から加熱路９１１を閉鎖する側に亘ってその位置が変化するミックスドア９２０が設けられている。ミックスドア９２０は、板状を呈しており、車幅方向（図面１４の表裏方向）に延びている回動軸９２０ｓを中心として、スイング可能である。 Further, inside the case 910, a mix door 920 whose position changes from the side that closes the bypass passage 912 to the side that closes the heating passage 911 is provided. The mix door 920 has a plate-like shape and can swing about a rotation shaft 920s extending in the vehicle width direction (front and back direction in FIG. 14).
　冷却用熱交換器９０１の吹き出し面９０１ａからミックスドア９２０の軌跡Ｌまでの間の空気の流路を接続路９１７とする。接続路９１７の一部には、接続路９１７を流れる空気の向きを調整する整流ガイド９１８が設けられている。 A connecting path 917 is an air flow path from the blowing surface 901 a of the cooling heat exchanger 901 to the locus L of the mix door 920 . A part of the connection path 917 is provided with a straightening guide 918 that adjusts the direction of the air flowing through the connection path 917 .
　ミックスドア９２０が加熱路９１１の入口を閉鎖した状態を完全冷房状態とする。完全冷房状態では、冷却用熱交換器９０１を通過して冷風となった空気がすべてバイパス路９１２を通過し、エアミックス空間９１３へ流れ込む。 The state in which the mix door 920 closes the entrance of the heating path 911 is the complete cooling state. In a completely cooled state, all the cold air that has passed through the cooling heat exchanger 901 passes through the bypass passage 912 and flows into the air mix space 913 .
　ミックスドア９２０がバイパス路９１２の入口を閉鎖した状態を完全暖房状態とする。完全暖房状態では、冷却用熱交換器９０１を通過した空気（冷風）がすべて加熱用熱交換器９０２を通過して温風となり、加熱路９１１を経由してエアミックス空間９１３へ流れ込む。 The state in which the mix door 920 closes the entrance of the bypass passage 912 is the complete heating state. In the complete heating state, all the air (cold air) that has passed through the cooling heat exchanger 901 passes through the heating heat exchanger 902 to become warm air, which flows into the air mix space 913 via the heating path 911 .
　ミックスドア９２０がバイパス路９１２の入口及び加熱路９１１の入口のいずれも塞いでいない状態を混合状態とする。混合状態では、加熱路９１１を通過した温風とバイパス路９１２を通過した冷風とがエアミックス空間９１３に流れ込み、混ざり合う。 A state in which the mix door 920 blocks neither the entrance of the bypass passage 912 nor the entrance of the heating passage 911 is called a mixed state. In the mixed state, the warm air that has passed through the heating path 911 and the cold air that has passed through the bypass path 912 flow into the air mix space 913 and mix.
　図１５には、バイパス路９１２の入口が僅かに開いている状態が示されている。バイパス路９１２の入口の流路面積が小さいと、冷却用熱交換器９０１により冷却された空気がバイパス路９１２に勢いよく流れ込んでしまう。即ち、ミックスドア９２０が完全暖房状態に近い位置に位置している場合にもかかわらず、エアミックス空間９１３に多くの冷風が流れこむ。流れ込んだ冷風がケース９１０のデフロスタ吐出部９１４から吐出されると、フロントガラスに向けて冷気が吹き付けられ、デフロスト機能が低下する。そこで、車両用空調装置９００には、ケース９１０の上面９１９から下方へ延びている板状の整流ガイド９２０が設けられている。 FIG. 15 shows a state in which the inlet of the bypass passage 912 is slightly open. If the passage area of the inlet of the bypass 912 is small, the air cooled by the cooling heat exchanger 901 will flow into the bypass 912 with force. That is, a large amount of cold air flows into the air mix space 913 even when the mix door 920 is positioned close to the fully heated state. When the cold air that has flowed in is discharged from the defroster discharge portion 914 of the case 910, the cold air is blown toward the windshield and the defrost function is deteriorated. Therefore, the vehicle air conditioner 900 is provided with a plate-like straightening guide 920 extending downward from the upper surface 919 of the case 910 .
　この整流ガイド９２０は、バイパス路９１２の入口よりも上流側に位置していることにより、バイパス路９１２の入口へ向かって流れる冷風を遮ることができる。冷却用熱交換器９０１により冷却された空気がバイパス路９１２に勢いよく流れ込むことを抑制できる。結果、冷風がそのままフロントガラスへ吹き付けられることを抑制でき、デフロスト機能を維持することができる。 The rectifying guide 920 is located upstream of the inlet of the bypass 912 , so it can block the cold air flowing toward the inlet of the bypass 912 . It is possible to prevent the air cooled by the cooling heat exchanger 901 from vigorously flowing into the bypass passage 912 . As a result, it is possible to suppress the cold air from blowing directly to the windshield, and it is possible to maintain the defrost function.

　ところで、完全冷房状態のときは、車室内を急速に冷却したい強い要望があり、多くの冷風を車室に供給することが求められている。しかし、特許文献１の整流ガイド９２０がバイパス路９１２の流路面積を縮小するように形成されているため、完全冷房状態のとき、整流ガイド９２０は、バイパス路９１２を流れる冷風の妨げとなり、流路抵抗が上昇してしまう。 By the way, there is a strong demand for rapid cooling of the vehicle interior when it is fully cooled, and it is required to supply a large amount of cool air to the vehicle interior. However, since the rectifying guide 920 of Patent Document 1 is formed so as to reduce the passage area of the bypass 912, the rectifying guide 920 interferes with the cold air flowing through the bypass 912 in a completely cooled state. Road resistance increases.

The connection path (29, 229, 329, 429, 529) is
The mix door (30, 230, 330, 430, 530) contacts when the mix door (30, 230, 330, 430, 530) closes the bypass (28, 228, 328, 428, 528). a possible first wall surface (51, 251, 351, 451, 551);
The mix door (30, 230, 330, 430, 530) can contact when the mix door (30, 230, 330, 430, 530) closes the heating path (27, 327, 427, 527). is in contact with the second wall surface (52, 252, 352, 452, 552),
The rectification guide (40, 60, 70, 240, 340, 440, 540) includes the first wall surface (51, 251, 351, 451, 551) and the second wall surface (52, 252, 352, 452, 552). ) and away from both
The downstream edge (44, 244, 344, 444, 544) of the straightening guide (40, 60, 70, 240, 340, 440, 540) is close to or overlaps with the locus (L1 to L5) ,
The straightening guide (40, 60, 70, 240, 340, 440, 540) faces the first wall surface (51, 251, 351, 451, 551). , 440, 540) is such that air flows towards said bypass (28, 228, 328, 428, 528) when said bypass (28, 228, 328, 428, 528) is slightly open. A vehicle air conditioner (10, 10A, 10B, 200, 300, 400, 500) is provided that includes a cold air straightening guide (41, 241, 341, 441, 541) configured to block the air.
　冷却用熱交換器からミックスドアの軌跡までの間の空気の流路を接続路とする。接続路には、接続路を流れる空気の向きを調整する板状の整流ガイドが設けられている。整流ガイドの下流側端辺は、ミックスドアの軌跡と近接し又は重なっている。 The connection path is the air flow path from the cooling heat exchanger to the trajectory of the mix door. The connecting path is provided with a plate-shaped rectifying guide that adjusts the direction of the air flowing through the connecting path. The downstream edge of the straightening guide is close to or overlaps with the trajectory of the mix door.
　整流ガイドは、第１壁面に対する整流ガイドの間隔が、バイパス路が僅かに開いているときにバイパス路へ向かって流れる空気を遮るように設定されている冷風整流ガイドを含んでいる。ミックスドアが完全暖房運転に近い位置（バイパス路が僅かに開いている状態）にあっても、デフロスト吹出口から吹き出される調和空気について必要以上に温度が低下することを防止して、デフロスト機能を維持することができる。 The rectifying guide includes a cold air rectifying guide whose distance from the first wall surface is set so as to block air flowing toward the bypass when the bypass is slightly open. Even if the mix door is in a position close to full heating operation (bypass passage is slightly open), the defrost function prevents the temperature of the conditioned air blown from the defrost outlet from dropping more than necessary. can be maintained.
　加えて、整流ガイドは、第１壁面および第２壁面の双方から離れている。ミックスドアが完全冷房状態の位置にあっては、冷却用熱交換器から吹き出された空気は、整流ガイドと第１壁面との間を流れることができる。冷風整流ガイドは、バイパス路へ向かって流れる空気の流路抵抗となりにくい。 In addition, the straightening guide is separated from both the first wall surface and the second wall surface. When the mix door is in the fully cooled position, the air blown out from the cooling heat exchanger can flow between the rectifying guide and the first wall surface. The cold air rectifying guide does not easily act as flow path resistance for the air flowing toward the bypass.
　以上より、ミックスドアが完全暖房状態に近い位置にあってはデフロスト機能を維持し、ミックスドアが完全冷房状態の位置にあってはバイパス路の流路抵抗の上昇を抑制することができる。 From the above, it is possible to maintain the defrost function when the mix door is in a position close to a fully heated state, and to suppress an increase in flow path resistance in the bypass when the mix door is in a fully cooled position.

A plate-like mix door 30 is arranged upstream of the heating path 27 and the bypass path 28 with respect to the direction of air flow. The mix door 30 changes its position by sliding vertically from the side (upper side) that closes the bypass passage 28 to the side (lower side) that closes the heating passage 27 .
　ミックスドア３０がスライドしてその位置が変化すると、バイパス路２８の入口と加熱路２７の入口の面積がそれぞれ変化する。即ち、バイパス路２８及び加熱路２７を流れるそれぞれの空気の流量を変化させることにより、調和空気の温度を変化させることができる。 When the mix door 30 slides and its position changes, the areas of the entrance of the bypass passage 28 and the entrance of the heating passage 27 change.

In the mixed state, the warm air that has passed through the heating path 27 and the cold air that has passed through the bypass path 28 are mixed to form conditioned air. A mixed state is sometimes referred to as a mixed mode.
　図３Ｃには、加熱路２７がミックスドア３０により完全に塞がれている完全冷房状態が示されている。完全冷房状態では、冷却用熱交換器１３を通過した空気（冷風）がすべてバイパス路２８を流れる。完全冷房状態を、フルクールモードと呼ぶことがある。 FIG. 3C shows a fully cooled state in which the heating path 27 is completely blocked by the mix door 30. In a completely cooled state, all the air (cold air) that has passed through the cooling heat exchanger 13 flows through the bypass passage 28 . A fully cooled state is sometimes called a full cool mode.

（整流ガイドの上流側端辺）
　各々の整流ガイド４０の上流側端辺４５は、すべて、冷却用熱交換器１３の吹き出し面１３ａに近接して配置されている。 (upstream edge of rectification guide)
All of the upstream side edges 45 of the straightening guides 40 are arranged close to the blowing surface 13 a of the cooling heat exchanger 13 .
　図５及び図６を参照する。整流ガイド４０の下流側端辺４４と、ミックスドア３０の上延出部３２とは、上ドア端辺３１が延びる方向（左右方向）についての寸法は、略等しい（図５の下流側端辺４４の寸法Ｗ１と上ドア端辺３１の寸法Ｗ２を参照）。ミックスドア３０の下延出部３４も、上延出部３２と同一の構成である。即ち、整流ガイド４０、ミックスドア３０、上延出部３２、下延出部３４とは、それぞれ、一方の側面５３から他方の側面５３に亘り一様な形状である。 See Figures 5 and 6. The downstream edge 44 of the straightening guide 40 and the upper extension 32 of the mix door 30 have approximately the same dimension in the direction in which the upper door edge 31 extends (horizontal direction) (the downstream edge in FIG. 5). (see dimension W1 at 44 and dimension W2 at top door edge 31). The lower extension 34 of the mix door 30 also has the same configuration as the upper extension 32 . That is, the rectifying guide 40, the mix door 30, the upwardly extending portion 32, and the downwardly extending portion 34 each have a uniform shape from one side surface 53 to the other side surface 53. As shown in FIG.

（実施例１の効果）
（冷風整流ガイドの機能）
　図４及び図５を参照する。ケース２０内の接続路２９には、接続路２９を流れる空気の向きを調整する板状の複数の整流ガイド４０が設けられている。各々の整流ガイド４０の下流側端辺４４は、ミックスドア３０の軌跡Ｌ１と重なっている。即ち、ミックスドア３０の位置が変化（スライドする）と、ミックスドア３０の上延出部３２および／又は下延出部３４は、整流ガイド４０の下流側端辺４４の突出部４４ａに接触する。 (Effect of Example 1)
(Function of cold air rectification guide)
Please refer to FIGS. The connecting path 29 in the case 20 is provided with a plurality of plate-like rectifying guides 40 for adjusting the direction of the air flowing through the connecting path 29 . A downstream side edge 44 of each rectifying guide 40 overlaps the trajectory L1 of the mix door 30 . That is, when the position of the mix door 30 changes (slides), the upwardly extending portion 32 and/or the downwardly extending portion 34 of the mix door 30 come into contact with the projecting portion 44a of the downstream side edge 44 of the straightening guide 40. .
　整流ガイド４０は、冷風整流ガイド４１を含んでいる。ケース２０の上面５１に対する冷風整流ガイド４１の間隔Ｄ１は、バイパス路２８が僅かに開いているとき（図５に示す状態）にバイパス路２８へ向かって流れる空気（矢印（１）参照））を遮るように設定されている。冷風整流ガイド４１によって、ミックスドア３０が完全暖房運転に近い位置（バイパス路２８が僅かに開いている状態）にあっても、デフロスト吹出口から吹き出される調和空気について必要以上に温度が低下することを防止して、デフロスト機能を維持することができる。 The straightening guide 40 includes a cold air straightening guide 41 . The distance D1 between the cool air rectifying guide 41 and the upper surface 51 of the case 20 is to prevent the air (see arrow (1)) flowing toward the bypass 28 when the bypass 28 is slightly open (the state shown in FIG. 5). set to block. Due to the cold air rectifying guide 41, even if the mix door 30 is in a position close to full heating operation (a state in which the bypass passage 28 is slightly open), the temperature of the conditioned air blown out from the defrost outlet drops more than necessary. It is possible to prevent this and maintain the defrost function.
（流路抵抗の上昇の抑制）
　加えて、各々の整流ガイド４０は、上面５１および下面５２の双方から離れている。ミックスドア３０が完全冷房状態（図３Ｃ参照）の位置にあっては、冷却用熱交換器１３から吹き出された空気は、整流ガイド４０（冷風整流ガイド４１）と上面５１との間を流れることができる。冷風整流ガイド４１は、バイパス路２８へ向かって流れる空気の流路抵抗が上昇することを抑制できる。 (Suppression of increase in flow path resistance)
In addition, each straightening guide 40 is spaced from both upper surface 51 and lower surface 52 . When the mix door 30 is in the fully cooled state (see FIG. 3C), the air blown out from the cooling heat exchanger 13 flows between the rectifying guide 40 (cold air rectifying guide 41) and the upper surface 51. can be done. The cool air rectifying guide 41 can suppress an increase in flow path resistance of the air flowing toward the bypass passage 28 .
　以上より、ミックスドア３０が完全暖房状態に近い位置にあってはデフロスト機能を維持し、ミックスドア３０が完全冷房状態の位置にあってはバイパス路２８の流路抵抗の上昇を抑制することができる。 From the above, it is possible to maintain the defrost function when the mix door 30 is in a position close to the fully heated state, and to suppress an increase in the flow path resistance of the bypass passage 28 when the mix door 30 is in a fully cooled position. can.
　なお、ミックスドア３０と整流ガイド４０の下流側端辺４４との間を空気が実質的にほとんど流れないように設定するならば、各々の整流ガイド４０の下流側端辺４４は、必ずしもミックスドア３０の軌跡Ｌ１に重なる必要はなく、近接していても良い。 If it is set so that substantially no air flows between the mix door 30 and the downstream edge 44 of each rectifying guide 40, the downstream edge 44 of each rectifying guide 40 does not necessarily have the mix door. It is not necessary to overlap the trajectory L1 of 30, and it may be close to it.
（複数の整流ガイド）
　加えて、整流ガイド４０は、冷風整流ガイド４１に対して、下面５２側へ離れて配置されている２つの一般整流ガイド４３,４３を含んでいる。エアミックスドア３０の上延出部３２が冷風整流ガイド４１よりも下方に位置する整流ガイド４０（一般整流ガイド４３）に接触するように、エアミックスドア３０が移動した場合であっても、一般整流ガイド４３の下流側端辺４４と上延出部３２とが接触又は近接して冷風の流れが制限され、バイパス路２８への過剰な量の冷風の流入を防止できる。すなわち、デフロスト機能を維持できるエアミックスドア３０の範囲を拡大することができる。 (multiple rectification guides)
In addition, the rectifying guide 40 includes two general rectifying guides 43, 43 that are spaced from the cold air rectifying guide 41 toward the lower surface 52 side. Even when the air mix door 30 moves so that the upper extension 32 of the air mix door 30 contacts the rectification guide 40 (general rectification guide 43) located below the cold air rectification guide 41, the general The downstream edge 44 of the rectifying guide 43 and the upper extending portion 32 contact or approach each other to limit the flow of cold air, thereby preventing an excessive amount of cold air from flowing into the bypass passage 28 . That is, it is possible to expand the range of the air mix door 30 that can maintain the defrost function.
（整流ガイドの下流側端辺の素材）
　各々の整流ガイド４０の下流側端辺４４は、弾性部材よりなる。そのためミックスドア３０の位置が変化して、ミックスドア３０が整流ガイド４０の下流側端辺４４に対して接触した場合であっても、整流ガイド４０がミックスドア３０の動作の妨げとなることを抑制できる。弾性部材は、例えばＥＰＤＭ、ＮＢＲ、Ｈ－ＮＢＲなどの材料が用いられる。 (Material of the downstream edge of the straightening guide)
A downstream side edge 44 of each straightening guide 40 is made of an elastic member. Therefore, even if the position of the mix door 30 changes and the mix door 30 comes into contact with the downstream side edge 44 of the rectification guide 40, the rectification guide 40 does not interfere with the operation of the mix door 30. can be suppressed. Materials such as EPDM, NBR, and H-NBR are used for the elastic member.
（整流ガイドの向き）
　加えて、整流ガイド４０は、前記冷却用熱交換器１３から吹き出される空気の吹き出し方向に沿って拡がるように形成されている。整流ガイド４０はそこを流れる空気の流れ方向に沿うよう設けられるので、空気の流路抵抗の上昇を招かない。 (Orientation of rectification guide)
In addition, the straightening guide 40 is formed so as to expand along the blowing direction of the air blown out from the cooling heat exchanger 13 . Since the rectifying guide 40 is provided along the flow direction of the air flowing therethrough, it does not lead to an increase in flow path resistance of the air.
（整流ガイドとミックスドアとの隙間）
　図５を参照する。ミックスドア３０の上ドア端辺３１は、上流側（前方）へ向かって延出する上延出部３２を有している。そのため、例えば、冷風整流ガイド４１に対して、上延出部３２が接触している場合、一般整流ガイド４３の下流側端辺４４と、ミックスドア３０の上流側の面３０ａとの間には、隙間が設定される。この隙間を空気が流れることができるため（矢印（２）参照））、冷却用熱交換器１３の吹き出し面１３ａから冷風整流ガイド４１と一般整流ガイド４３との間に吹き出た冷風成分は、加熱路２８に向けて流れることができる。すなわち、適切な量の温風を加熱路２８に供給することができる。空気の流路抵抗の上昇を招かない。 (Gap between rectification guide and mix door)
Please refer to FIG. An upper door edge 31 of the mix door 30 has an upper extending portion 32 extending upstream (forward). Therefore, for example, when the upper extending portion 32 is in contact with the cold air straightening guide 41, there is a gap between the downstream side edge 44 of the general straightening guide 43 and the upstream side surface 30a of the mix door 30. , a gap is set. Since air can flow through this gap (see arrow (2))), the cold air component blown out between the cold air straightening guide 41 and the general straightening guide 43 from the blowing surface 13a of the cooling heat exchanger 13 is heated. It can flow towards the channel 28 . That is, an appropriate amount of warm air can be supplied to the heating path 28 . It does not cause an increase in air flow resistance.
　加えて、上延出部３２は、弾性部材によりなる。そのため、ミックスドア３０の位置が変化して、ミックスドア３０が整流ガイド４０の下流側端辺４４に対して接触した場合であっても、整流ガイド４０がミックスドア３０の動作の妨げとなることを抑制できる。弾性部材は、例えばＥＰＤＭ、ＮＢＲ、Ｈ－ＮＢＲなどの材料が用いられる。 In addition, the upper extending portion 32 is made of an elastic member. Therefore, even if the position of the mix door 30 changes and the mix door 30 comes into contact with the downstream edge 44 of the rectification guide 40, the rectification guide 40 does not interfere with the operation of the mix door 30. can be suppressed. Materials such as EPDM, NBR, and H-NBR are used for the elastic member.
（整流ガイドの上流側端辺の位置）
　各々の整流ガイド４０の上流側端辺４５は、すべて、冷却用熱交換器１３の吹き出し面１３ａに近接して配置されている。そのため、吹き出し面１３ａから吹き出された空気は、吹き出された直後に各々の整流ガイド４０Ｃによりガイドされる。吹き出し面１３ａと上流側端辺４５Ｃとの間を意図せずに上下方向に流れる空気の量を減少することができる。意図せずにバイパス路２８へ流入する空気の量を減少することができるので、より効果的にデフロスト機能を維持できる。 (Position of the upstream side edge of the straightening guide)
All of the upstream side edges 45 of the straightening guides 40 are arranged close to the blowing surface 13 a of the cooling heat exchanger 13 . Therefore, the air blown out from the blowing surface 13a is guided by each rectifying guide 40C immediately after being blown out. It is possible to reduce the amount of air that unintentionally flows vertically between the blowout surface 13a and the upstream edge 45C. Since the amount of air that unintentionally flows into the bypass passage 28 can be reduced, the defrost function can be maintained more effectively.
（整流ガイドの寸法とミックスドアとの寸法）
　図５及び図６を参照する。整流ガイド４０の下流側端辺４４と、ミックスドア３０の延出部３２，３４とは、ドア端辺３１，３３が延びる方向（左右方向）についての寸法が、略等しいことが好ましい。ミックスドア３０の位置が完全暖房状態から僅かに下方へ移動し、上延出部３２が整流ガイド４０（冷風整流ガイド４１）の下流側端辺４４と近接または接触しているとき（図５の状態）、バイパス路２８に向かって流れる空気（図５における矢印（１））が遮られる。このとき、下流側端辺４４の寸法Ｗ１と上延出部３２の寸法Ｗ２とが略等しいことで、温調装置１２の左右方向において、意図した範囲で本実施例の効果を得ることができる。 (Dimensions of rectification guide and dimensions of mix door)
Please refer to FIGS. It is preferable that the downstream side edge 44 of the flow straightening guide 40 and the extending portions 32 and 34 of the mix door 30 have approximately the same dimension in the direction in which the door edge sides 31 and 33 extend (horizontal direction). When the position of the mix door 30 moves slightly downward from the fully heated state, and the upwardly extending portion 32 is close to or in contact with the downstream edge 44 of the rectifying guide 40 (cold air rectifying guide 41) (see FIG. 5). state), the air flowing toward the bypass 28 (arrow (1) in FIG. 5) is blocked. At this time, since the dimension W1 of the downstream side edge 44 and the dimension W2 of the upper extending portion 32 are substantially equal, the effect of the present embodiment can be obtained within the intended range in the horizontal direction of the temperature control device 12. .

　なお、整流ガイド６０はケース２０Ａの射出成型工程の観点で、いわゆるアンダーカット形状となる。整流ガイド６０を含むケース２０Ａを成形する金型は、例えば、固定型に対して左右方向に移動する可動型に加えて、前後方向に移動するスライド型を用いる。 It should be noted that the straightening guide 60 has a so-called undercut shape from the viewpoint of the injection molding process of the case 20A. As a mold for molding the case 20A including the rectifying guide 60, for example, in addition to a movable mold that moves in the horizontal direction with respect to a fixed mold, a slide mold that moves in the front-rear direction is used.
　整流ガイド６０を段差状とすることにより、ミックスドア３０の位置と調和空気の温度とのリニアリティの向上をより細かく調整することができる。 By making the rectifying guide 60 stepped, it is possible to finely adjust the improvement of the linearity between the position of the mix door 30 and the temperature of the conditioned air.
