Description

この発明は、２つの通気路の合流部位に配置される空調用バッフルプレート及びこの空調用バッフルプレートを利用した空調ユニットの温調ユニット部の構造に関する。   The present invention relates to an air conditioning baffle plate disposed at a confluence portion of two air passages and a structure of a temperature control unit portion of an air conditioning unit using the air conditioning baffle plate.

当社では、クールデフ現象を防止するために、加熱用熱交換器が冷却用熱交換器の車両進行方向の前方側に位置し、加熱用熱交換器を通過した空気の流れる温風通路が加熱用熱交換器を迂回した空気の流れる冷風通路に対し車両進行方向の前方に位置し、更に、デフ吹出用開口部及びフット吹出用開口部がベント吹出用開口部よりも車両進行方向の前方に位置する車両用空調装置のエアコンユニットを開発している（例えば、特許文献１を参照）。   In our company, in order to prevent the cool differential phenomenon, the heating heat exchanger is located in front of the cooling heat exchanger in the vehicle traveling direction, and the hot air passage through which the air passing through the heating heat exchanger flows is used for heating. It is located in the front of the vehicle traveling direction with respect to the cold air passage through which the air bypassing the heat exchanger flows, and the differential blowing opening and the foot blowing opening are located in front of the vent blowing opening in the vehicle traveling direction. An air conditioner unit for a vehicle air conditioner has been developed (see, for example, Patent Document 1).

また、ブロワユニット部と温調ユニット部とからなる車両用のセミ一体型空調ユニットにおいて、冷却用熱交換器が車両進行方向の前方側に位置し、加熱用熱交換器が車両進行方向の後方側に位置するものであるが、冷風通路と温風通路との合流部位にバッフルプレート等から構成された温調ガイド手段を設けるようにした構成のものが既に開発されている（例えば、特許文献２を参照）。
特開２０００−２７２３２９号公報 特開２００２−２７４１４９号公報 Further, in the semi-integrated air conditioning unit for a vehicle including the blower unit and the temperature control unit, the cooling heat exchanger is located on the front side in the vehicle traveling direction, and the heating heat exchanger is located on the rear side in the vehicle traveling direction. Although it is located on the side, a configuration in which a temperature control guide means constituted by a baffle plate or the like is provided at the confluence portion of the cold air passage and the hot air passage has already been developed (for example, patent document) 2).
JP 2000-272329 A JP 2002-274149 A

しかしながら、特許文献１に記載の車両用空調装置のエアコンユニットは、その図１、図３の模式図では、加熱用熱交換器が直立して配置された状態で示されているが、近年における空調ユニットの小型化の要請に伴い、加熱用熱交換器は例えば車両進行方向の前方側に傾倒して配置されるので、実質的には、加熱用熱交換器を通過した空気が流れる温風通路の端部とデフ吹出用開口部、ベント吹出用開口部との距離はより離れた状態になることが想定される。このため、冷風通路からの冷風に押される等して、温風がベント吹出用開口部の上流側まで十分に供給されないことが懸念される。   However, the air conditioner unit of the vehicle air conditioner described in Patent Document 1 is shown in a state where the heat exchanger for heating is arranged upright in the schematic diagrams of FIGS. 1 and 3. With the demand for downsizing of the air conditioning unit, the heating heat exchanger is disposed, for example, tilted forward in the vehicle traveling direction, so that the hot air that flows through the heating heat exchanger substantially flows. It is assumed that the distance between the end of the passage, the differential outlet, and the vent outlet is further away. For this reason, there is a concern that the hot air is not sufficiently supplied to the upstream side of the vent blowing opening, for example, pushed by the cold air from the cold air passage.

この点、特許文献２と同様に、冷風通路と温風通路との合流部位にバッフルプレートを配置することで、ベント吹出用開口部の上流側に温風を適宜送り込むことが考えられる。   In this regard, similarly to Patent Document 2, it is conceivable that hot air is appropriately sent to the upstream side of the vent blowing opening by disposing a baffle plate at a confluence portion between the cold air passage and the hot air passage.

ところが、同じ空調ユニットを搭載する場合でも、車種の違いから、空調ダクトの引き回しレイアウト、吹出口の開口位置が僅かに違うが、このような僅かな違いでも吹出空気の温度が変わることが考えられる。また、輸出先によっては使用環境などからフット吹出空気量を国内仕様に比し増加させたいとされることがある。これに対し、これまでの空調ユニットでは、当該空調ユニットの大部分の構成を共通にしつつこのような要請に応えるものはなかった。   However, even when the same air conditioning unit is installed, the layout of the air conditioning duct and the opening position of the air outlet are slightly different due to the difference in the vehicle type, but it is considered that the temperature of the air can be changed even by such a slight difference. . Also, depending on the export destination, it may be desired to increase the amount of air blown out from the domestic specifications due to the usage environment. On the other hand, none of the conventional air conditioning units meets such a demand while sharing the most of the configurations of the air conditioning units.

そこで、本発明は、車両進行方向の前方に加熱用熱交換器、車両進行方向の後方に冷却用熱交換器を配置した空調ユニットであって、加熱用熱交換器等について実際に車両に搭載される構成とした場合において、簡易な調整で車種や仕様による差異があってもベント吹出空気とフット吹出空気とについて温度コントロール性を適切に行うことを可能とした空調用バッフルプレート及びこの空調用バッフルプレートを利用した空調ユニットを提供することを目的とするものである。   Therefore, the present invention is an air conditioning unit in which a heat exchanger for heating is disposed in front of the vehicle traveling direction and a cooling heat exchanger is disposed in the rear of the vehicle traveling direction, and the heating heat exchanger and the like are actually mounted on the vehicle. The air-conditioning baffle plate and the air-conditioning baffle plate capable of appropriately controlling the temperature of the vent blown air and the foot blown air even if there is a difference depending on the vehicle type and specifications by simple adjustment. It aims at providing the air-conditioning unit using a baffle plate.

本発明に係る空調用バッフルプレートは、両端が開口して温風を所望の開口部に導くことを可能とした通路部と、この通路部間に配置されて冷風を前記温風と交差する方向に導くことを可能とすると共に前記通路部の両開口端と同方向にも開口し温風を所望の開口部に導くことも可能とした吹き抜け部とを有し、前記吹き抜け部のうち温風の風上側となる前記通路部間に温風抑制部が架設されていることを特徴としている（請求項１）。   The baffle plate for air conditioning according to the present invention has a passage portion that is open at both ends to allow the hot air to be guided to a desired opening, and a direction in which the cold air intersects the hot air by being disposed between the passage portions. A blow-off portion that opens in the same direction as both opening ends of the passage portion and that can also guide the hot air to a desired opening portion. A warm air suppressing portion is constructed between the passage portions on the windward side of the vehicle (claim 1).

本発明に係る空調ユニットの温調ユニット部は、冷却用熱交換器と加熱用熱交換器とを、前記冷却用熱交換器が前記加熱用熱交換器に対し車両進行方向の後方となるようにユニットケース内に配置し、前記加熱用熱交換器をバイパスした空気が流れる冷風通路と、前記加熱用熱交換器を通過した空気が流れる温風通路と、ベント吹出用開口部、デフ吹出用開口部、及びフット吹出用開口部とを前記ユニットケースに形成すると共に、前記冷風通路と温風通路との合流部位に、一方端部が前記温風通路に接続し、他方端部が前記ベント吹出用開口部の上流側に開口したバッフルプレートが配置され、このバッフルプレートは、両端が開口して温風を前記ベント吹出用開口部に導くことを可能とした通路部と、この通路部間に配置されて冷風を前記温風と交差する方向に導くことを可能とすると共に前記通路部の両開口端と同方向にも開口し温風を前記ベント吹出用開口部に導くことも可能とした吹き抜け部とを有し、前記吹き抜け部のうち温風の風上側となる前記通路部間に温風抑制部が架設されていることを特徴としている（請求項２）。   The temperature control unit portion of the air conditioning unit according to the present invention includes a cooling heat exchanger and a heating heat exchanger, and the cooling heat exchanger is located behind the heating heat exchanger in a vehicle traveling direction. Arranged in the unit case, the cool air passage through which the air bypassing the heating heat exchanger flows, the hot air passage through which the air that has passed through the heating heat exchanger flows, the vent blowing opening, and the differential blowing An opening and an opening for foot blowing are formed in the unit case, and one end is connected to the hot air passage, and the other end is connected to the vent. A baffle plate opened on the upstream side of the blowout opening is disposed, and the baffle plate has a passage portion that opens at both ends and allows the hot air to be guided to the vent blowout opening portion, and between the passage portions. Placed in the cold air before It has a blow-off portion that can be guided in a direction intersecting with the warm air and that also opens in the same direction as both opening ends of the passage portion, and can also guide the warm air to the vent blowing opening. Further, a hot air suppression portion is constructed between the passage portions on the windward side of the hot air among the blow-through portions (claim 2).

よって、この発明によれば、バッフルプレートの通路部間に配された吹き抜け部を通過してベント吹出用開口部に向けて流れようとする温風は、温風抑制部を設けたことで、吹き抜け部の入口部分において通路面積が縮小されるので吹き抜け部の通路抵抗が増大し、フット吹出用開口部への温風量が減少する。この温風抑制部は、冷風通路に対し略平行に配置されているので、温風抑制部の高さ調整により冷風通路の通路抵抗増大を招くこともない。   Therefore, according to the present invention, the warm air that tries to flow toward the vent blowing opening through the blow-off portion disposed between the passage portions of the baffle plate is provided with the warm air suppressing portion. Since the passage area is reduced at the entrance portion of the blow-through portion, the passage resistance of the blow-through portion is increased, and the amount of hot air to the foot blow-off opening portion is reduced. Since the hot air suppressing part is arranged substantially parallel to the cold air passage, the height resistance of the hot air suppressing part is not increased, thereby increasing the passage resistance of the cold air passage.

これに伴い、バッフルプレートの温風抑制部の高さを変えることによって、ベント吹出用開口部に送られる温風量とフット吹出用開口部に送られる温風量とを反比例的に増減させることができる。従って、車種毎、乃至は同車種でも輸出用仕様と国内仕様とで吹出口の位置、空調ダクトの引き回しレイアウト、必要な吹出空気量等が異なることがあるが、このような場合でも、バッフルプレートの温風抑制部の高さを変えるのみで、ベント吹出空気、フット吹出空気の温度や風量について、利用者の要望に応えることができるよう調整することが可能となる。   Accordingly, by changing the height of the hot air suppressing portion of the baffle plate, the amount of hot air sent to the vent blowing opening and the amount of hot air sent to the foot blowing opening can be increased or decreased inversely. . Therefore, the position of the air outlet, the layout of the air-conditioning duct, the required amount of air to be blown, etc. may differ between the export specification and the domestic specification for each vehicle type or the same vehicle type. It is possible to adjust the temperature and the air volume of the vent blown air and the foot blown air so as to meet the demands of the user only by changing the height of the hot air suppression unit.

以下、この発明の実施形態を図面により説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１及び図２において、温調ユニット部１の実施形態の一例が示されている。この温調ユニット部１は、内外気導入口、内外気切換ドア、送風機を少なくとも有するブロワユニット部（図示せず）と連結されることで、車両のセンターコンソール部に搭載されるセミ一体型の縦置形式の空調ユニットを構成している。   In FIG.1 and FIG.2, an example of embodiment of the temperature control unit part 1 is shown. The temperature control unit 1 is connected to a blower unit (not shown) having at least an inside / outside air introduction port, an inside / outside air switching door, and a blower, so that it is a semi-integrated type mounted on the center console portion of the vehicle. It constitutes a vertical air conditioning unit.

この温調ユニット部１は、ブロワユニット部から送られてきた空気を冷却するエバポレータ等の冷却用熱交換器３、この冷却用熱交換器３で冷却された空気を再加熱するヒータコア等の加熱用熱交換器４、及び冷却用熱交換器３と加熱用熱交換器４との間に配置されて加熱用熱交換器４に送られる空気とバイパスする空気との割合を調整するエアミックスドア５をユニットケース６内に有している。このうち、加熱用熱交換器４は、温調ユニット部１の小型化の要請等から、この実施形態では、頭部が車両進行方向の前方側に傾倒して配置されている。   The temperature control unit 1 is configured to heat a cooling heat exchanger 3 such as an evaporator that cools the air sent from the blower unit, and a heater core that reheats the air cooled by the cooling heat exchanger 3. Heat exchanger 4 and an air mix door that is arranged between cooling heat exchanger 3 and heating heat exchanger 4 and adjusts the ratio of air sent to heating heat exchanger 4 and bypassed air 5 in the unit case 6. Among them, the heat exchanger 4 for heating is arranged with the head tilted forward in the vehicle traveling direction in this embodiment because of a request for downsizing the temperature control unit 1 or the like.

また、この温調ユニット部１は、ユニットケース６内に、加熱用熱交換器４に対し下流側となる車両進行方向前方側にて、この加熱用熱交換器で再加熱された空気が通過する温風通路７が形成されていると共に、冷却用熱交換器３の下流側で且つ加熱用熱交換器４及びエアミックスドア５に対し図上略上方となる側に冷風通路８が形成されている。   Further, the temperature control unit 1 passes through the unit case 6 through the air reheated by the heating heat exchanger on the front side in the vehicle traveling direction, which is the downstream side of the heating heat exchanger 4. The hot air passage 7 is formed, and the cold air passage 8 is formed on the downstream side of the cooling heat exchanger 3 and on the side substantially upward in the drawing with respect to the heating heat exchanger 4 and the air mix door 5. ing.

そして、温調ユニット部１の温風通路７と冷風通路８とが合流する部位よりも下流側において、センターベント吹出用開口部１０、デフ吹出用開口部１１、フット吹出用開口部１２が、ユニットケース６に適宜開口している。更に、図２に示される様に、ベント吹出用開口部１０の車両幅方向に沿って両側となるように、サイドベント吹出用開口部１３、１３がユニットケース６に適宜開口している。   Then, on the downstream side of the portion where the hot air passage 7 and the cold air passage 8 of the temperature control unit 1 merge, a center vent blowing opening 10, a differential blowing opening 11, and a foot blowing opening 12 are provided. The unit case 6 is appropriately opened. Further, as shown in FIG. 2, side vent blowing openings 13, 13 are appropriately opened in the unit case 6 so as to be on both sides of the vent blowing opening 10 along the vehicle width direction.

これら吹出用開口部１０、１１、１２、１３は図示しないダクトを介して車室内に開口した吹出口と連通している。このうち、センターベント吹出用開口部１０、サイドベント吹出用開口部１３、デフ吹出用開口部１１には、吹出モード切換ドア１４、１５、１６が各開口部１０、１３、１１を開閉するために回転可能に配置されている。更にまた、この実施形態では、加熱用熱交換器４の下流側からフット吹出用開口部１２まで空気を案内するエアガイド１７が形成され、このエアガイド１６とユニットケース６との間の流路上に吹出モード切換ドア１８が回転可能に配置されて、フット吹出用開口部１２の開閉を可能にしている。   These blowout openings 10, 11, 12, and 13 communicate with a blowout opening that opens into the vehicle compartment via a duct (not shown). Among these, in the center vent blowing opening 10, the side vent blowing opening 13, and the differential blowing opening 11, the blowing mode switching doors 14, 15, and 16 open and close the openings 10, 13, and 11, respectively. It is arranged to be rotatable. Furthermore, in this embodiment, an air guide 17 for guiding air from the downstream side of the heat exchanger 4 for heating to the foot blowing opening 12 is formed, and on the flow path between the air guide 16 and the unit case 6. The blowing mode switching door 18 is rotatably arranged to open and close the foot blowing opening 12.

そして、温調ユニット部１は、ユニットケース６の車両進行方向の最も後方において、ブロワユニット部と連結するための開口部（図示せず）が形成され、これに伴い、冷却用熱交換器３は、加熱用熱交換器４に対し車両進行方向後方側に配置されている。しかるに、ベント吹出用開口部１０、デフ吹出用開口部１１を車両進行方向の前方側に移行させても、冷却用熱交換器３の頂部は、ベント吹出用開口部１０、１３に対しその直下より車両進行方向の後方にずれて位置させることができる。このため、冷却用熱交換器３を通過した空気がベント吹出用開口部１０、１３に向う流れのカーブを緩やかにすることができるので、空気抵抗を相対的に小さくすることができる。また、従来の配置方法に従って車両進行方向前方側に冷却用熱交換器３が配置される場合に比し、デフ吹出用開口部１１の開口面積を十分に確保することもできる。   The temperature control unit 1 is formed with an opening (not shown) for connecting to the blower unit at the rearmost position of the unit case 6 in the vehicle traveling direction, and accordingly, the cooling heat exchanger 3 is connected. Is arranged on the rear side in the vehicle traveling direction with respect to the heat exchanger 4 for heating. However, even if the vent blowing opening 10 and the differential blowing opening 11 are shifted to the front side in the vehicle traveling direction, the top of the cooling heat exchanger 3 is directly below the vent blowing openings 10 and 13. Further, it can be shifted and positioned rearward in the vehicle traveling direction. For this reason, since the curve of the flow of the air that has passed through the cooling heat exchanger 3 toward the vent blowing openings 10 and 13 can be made gentle, the air resistance can be relatively reduced. Moreover, compared with the case where the heat exchanger 3 for cooling is arrange | positioned in the vehicle advancing direction front side according to the conventional arrangement | positioning method, the opening area of the opening part 11 for differential blowing can also be ensured sufficiently.

ところで、本件発明では、図１及び図２に主に示されるように、冷風通路８と温風通路７とが合流する部位においてバッフルプレート２０が設けられている。このバッフルプレート２０は、図３及び図５に示されるように、通路部２１と吹き抜け部２５を交互に並行となるように配置して構成されている。そして、バッフルプレート２０は、温調ユニット部１のユニットケース６等とは別個の部材であり、図４に示されるように、ユニットケース６を車両の幅方向に沿って分割した状態で搭載される。   By the way, in this invention, as mainly shown by FIG.1 and FIG.2, the baffle plate 20 is provided in the site | part where the cool air path 8 and the warm air path 7 merge. As shown in FIGS. 3 and 5, the baffle plate 20 is configured by arranging the passage portions 21 and the blow-off portions 25 alternately in parallel. The baffle plate 20 is a separate member from the unit case 6 and the like of the temperature control unit 1, and is mounted in a state where the unit case 6 is divided along the width direction of the vehicle as shown in FIG. The

バッフルプレート２０のうち通路部２１は、一方端が温風通路７と接続し他方端がベント吹出用開口部１０、１３のデフ吹出用開口部１１近傍部位に開口していると共に冷風通路８側に緩やかに膨らむ円弧を描く底面２２を有している。また、通路部２１の底面２２の両側側方からは壁部２３、２３が立設している。これにより、通路部２１は、車両進行方向の前方にも開放されて断面が略Ｕ字形状を成し、加熱用熱交換器１２により加熱された温風が、図５の矢印（ｉ）として示されるように、温風通路７からバッフルプレート２０の通路部２１を通ってベント吹出用開口部１０、１３及びデフ吹出用開口部１１近傍まで送られるので、加熱用熱交換器１２の頭部が車両進行方向の前方側に傾倒していても、必要量の温風が確実にベント吹出用開口部１０、１３及びデフ吹出用開口部１１に供給されて、クールデフ現象やクールサイドベント現象が生ずるのを防止することができる。   Of the baffle plate 20, the passage portion 21 has one end connected to the hot air passage 7 and the other end opened to the vent blowing openings 10 and 13 in the vicinity of the differential blowing opening 11 and the cold air passage 8 side. It has a bottom surface 22 that draws an arc that gently swells. Further, wall portions 23, 23 are erected from both sides of the bottom surface 22 of the passage portion 21. Accordingly, the passage portion 21 is also opened forward in the vehicle traveling direction and has a substantially U-shaped cross section. The warm air heated by the heating heat exchanger 12 is indicated by an arrow (i) in FIG. As shown in the figure, since the warm air passage 7 is sent through the passage portion 21 of the baffle plate 20 to the vicinity of the vent blowing openings 10 and 13 and the differential blowing opening 11, the head of the heating heat exchanger 12 is shown. Even if the vehicle is tilted forward in the vehicle traveling direction, the required amount of warm air is reliably supplied to the vent blowing openings 10 and 13 and the differential blowing opening 11 so that the cool differential phenomenon and the cool side vent phenomenon occur. It can be prevented from occurring.

これに対し、吹き抜け部２５は、前記通路部２１の壁部２３、２３を共用する一方、通路部２１のような底面を有さず、一方が冷風通路８側に開口し他方がデフ吹出用開口部１１及びフット吹出開口部１２側に開口している。これにより、加熱用熱交換器１２をバイパスした冷風が、図５の矢印（ii）として示されるように、冷風通路８からバッフルプレート２０の吹き抜け部２５を通ってデフ吹出用開口部１１及びフット吹出開口部１２の近傍まで送られる。更に、吹き抜け部２５は、一方がベント吹出用開口部１０、１３の近傍に開口していると共に他方は温風通路７と接続しているが、この温風通路７と接続する入口部分３０には温風抑制部２６が配置されている。この温風抑制部２６は、入口部分３０の反対側端に設けられた補強部２７と同様にバッフルプレート２０の補強としての役割も果たす。   On the other hand, the blow-off portion 25 shares the wall portions 23 and 23 of the passage portion 21, but does not have a bottom surface like the passage portion 21, one is opened to the cold air passage 8 side, and the other is for differential blowing. It opens to the opening 11 and the foot outlet opening 12 side. As a result, the cold air bypassing the heating heat exchanger 12 passes through the blow-off portion 25 of the baffle plate 20 from the cold air passage 8 as shown by an arrow (ii) in FIG. It is sent to the vicinity of the blowout opening 12. Further, one of the blow-off portions 25 is opened in the vicinity of the vent blowing openings 10 and 13 and the other is connected to the warm air passage 7. Is provided with a warm air suppression unit 26. The hot air suppressing portion 26 also serves as a reinforcement for the baffle plate 20 in the same manner as the reinforcing portion 27 provided at the opposite end of the inlet portion 30.

前記温風抑制部２６は、通路部２１の底面２２と同じ側から起立するようにして壁部２３、２３間に架設されている。この温風抑制部２６を有することで、図５に示されるように、吹き抜け部２５の温風の上流側となる入口部分３０が狭くなり（或いは無くなり）、この吹き抜け部２５に入口部分３０から入ることのできた温風は、図５の矢印（iii ）として示されるように、前記矢印（ii）として示す冷風の流れに押される等して当該冷風と同様の方向に大きく向きを変えて、デフ吹出用開口部１１及びフット吹出開口部１２の近傍まで送られる。この温風抑制部２６の高さは一律ではなく、温調ユニット部１内における加熱用熱交換器４の傾斜角度等の配置や吹出用開口部１０、１１、１２、１３と接続するダクトを引き回すレイアウト、車室内に開口する各吹出口の位置、要望される吹出空気量等を考慮して適切な寸法に決定されるものである。   The hot air suppressing part 26 is constructed between the wall parts 23 and 23 so as to stand up from the same side as the bottom surface 22 of the passage part 21. By having this hot air suppression part 26, as shown in FIG. 5, the inlet part 30 on the upstream side of the hot air of the blow-off part 25 becomes narrower (or disappears), and the blow-off part 25 extends from the inlet part 30. The hot air that was able to enter, as shown by the arrow (iii) in FIG. 5, is largely changed in the same direction as the cold air by being pushed by the flow of the cold air shown by the arrow (ii), It is sent to the vicinity of the differential blowing opening 11 and the foot blowing opening 12. The height of the hot air suppression unit 26 is not uniform, and the duct connected to the arrangement of the inclination angle of the heat exchanger 4 for heating in the temperature control unit 1 and the blowing openings 10, 11, 12, 13 is not provided. The dimensions are determined in consideration of the layout to be routed, the position of each outlet opening in the vehicle interior, the desired amount of blown air, and the like.

すなわち、本願の実施形態のバイレベルモード時においては、図６（ａ）に示されるように、温風抑制部２６の高さＬ１を壁部２３と略同じ３０ｍｍの寸法とした場合には、温風抑制部２６により吹き抜け部２５の入口部分３０が閉鎖された状態にあるため、温風が吹き抜け部２５の入口部分３０を通過してフット吹出用開口部１２に向かうことがないので、フット吹出用開口部１２への温風供給量が相対的に少なくなり、エアミックスドアの開度が２０％から１００％の間では、図６（ｂ）に示されるように、ベント吹出空気の平均温度の方がフット吹出空気の平均温度よりも高くなるという逆転現象が生ずる。   That is, in the bi-level mode of the embodiment of the present application, as shown in FIG. 6A, when the height L1 of the hot air suppressing portion 26 is approximately the same as the wall portion 23, the dimension is 30 mm. Since the warm air suppression unit 26 closes the inlet portion 30 of the blow-off portion 25, the warm air does not pass through the inlet portion 30 of the blow-through portion 25 and travel toward the foot blowing opening 12. When the amount of hot air supplied to the blowout opening 12 is relatively small and the opening degree of the air mix door is between 20% and 100%, as shown in FIG. A reverse phenomenon occurs in which the temperature is higher than the average temperature of the foot blowing air.

また、本願の実施形態のバイレベルモード時においては、図７（ａ）に示されるように、温風抑制部２６の高さＬ２を２０ｍｍの寸法とした場合には、温風が吹き抜け部２５の温風上流側となる入口部分３０が開き、フット吹出用開口部１２への温風供給量が図５の場合に比較して多くなるが、入口部分３０の通路抵抗が大きいためフット吹出用開口部１２への温風供給量が充分とは言えない。このため、本願の実施形態の場合では、図７（ｂ）に示されるように、ベント吹出空気の温度とフット吹出空気の温度との差が１５℃以上であることが必要なところ、両平均温度の温度差が１５℃よりも小さいという現象が生ずる。   Further, in the bi-level mode of the embodiment of the present application, as shown in FIG. 7A, when the height L2 of the hot air suppressing part 26 is set to a dimension of 20 mm, the hot air is blown through the air blowing part 25. The inlet portion 30 on the upstream side of the warm air is opened, and the amount of hot air supplied to the foot blowing opening 12 is larger than that in the case of FIG. It cannot be said that the amount of hot air supplied to the opening 12 is sufficient. For this reason, in the case of the embodiment of the present application, as shown in FIG. 7B, the difference between the temperature of the vent blown air and the temperature of the foot blown air needs to be 15 ° C. or higher. A phenomenon occurs in which the temperature difference between the temperatures is less than 15 ° C.

これに対し、本願の実施形態のバイレベルモード時においては、図８（ａ）に示されるように、温風抑制部２６の高さＬ３を１０ｍｍの寸法とした場合には、温風が吹き抜け部２５の温風上流側となる入口部分３０が更に開き、入口部分３０の通路抵抗がより小さくなるので、フット吹出用開口部１２への温風供給量が図５に比較して一層多くなる。このため、本願の実施形態の場合では、図８（ｂ）に示されるように、ベント吹出空気の平均温度とフット吹出空気の平均温度とについて１５℃以上の適切な温度差を得ることができる。しかるに、本願の実施形態では、温風抑制部２６の適切な高さが１０ｍｍであるため、この高さの温風抑制部２６が形成されたバッフルプレート２０を搭載する。   On the other hand, in the bi-level mode of the embodiment of the present application, as shown in FIG. 8A, when the height L3 of the hot air suppression unit 26 is set to a dimension of 10 mm, the hot air blows through. Since the inlet portion 30 on the upstream side of the hot air of the portion 25 is further opened and the passage resistance of the inlet portion 30 is further reduced, the amount of hot air supplied to the foot blowing opening 12 is further increased compared to FIG. . For this reason, in the case of the embodiment of the present application, as shown in FIG. 8B, an appropriate temperature difference of 15 ° C. or more can be obtained for the average temperature of the vent blown air and the average temperature of the foot blown air. . However, in the embodiment of the present application, since the appropriate height of the hot air suppression unit 26 is 10 mm, the baffle plate 20 in which the hot air suppression unit 26 having this height is formed is mounted.

もっとも、温風抑制部２６の適切な高さが１０ｍｍであることは、上述したように、本願の実施形態に関してのものである。すなわち、加熱用熱交換器４の傾斜角度、温風通路７の幅等の諸条件によっては２０ｍｍの高さの方がベント吹出空気の温度とフット吹出空気の温度とについて適切な温度差を得ることもあり得る。また、輸出仕様でフット吹出空気量を相対的に増加させたい場合には、温風抑制部２６をより低く５ｍｍの高さにすることもあり得る。   However, the appropriate height of the hot air suppression unit 26 is 10 mm, as described above, is related to the embodiment of the present application. That is, depending on various conditions such as the angle of inclination of the heat exchanger 4 for heating and the width of the hot air passage 7, a height of 20 mm provides an appropriate temperature difference between the temperature of the vent air and the temperature of the foot air. It can happen. Further, when it is desired to relatively increase the amount of foot blowing air in the export specification, the warm air suppression unit 26 may be lowered to a height of 5 mm.
