Description

車両用空調装置Vehicle air conditioner
　本発明は、車両用空調装置に関する。 The present invention relates to a vehicle air conditioner.
　自動車等の車両に適用される車両用空調装置は、エバポレータ及びヒータコアを収容する筐体内において、エバポレータを通じて発生する冷風と、冷風の一部を用いてヒータコアが生成する温風と、を適宜混合することで所望の温度の空気を車内に送風する。このような装置の具体例として、下記特許文献１に記載されたものが知られている。特許文献１に係る空調装置は、ケーシング（空調ユニット）内に、エバポレータを通過した風が流れる冷風通路と、ヒータコアを通過した風が流れる温風通路と、これら冷風通路を通過した冷風と温風通路を通過した温風の混合割合を調節するためのミックスダンパと、を備えている。 A vehicle air conditioner applied to a vehicle such as an automobile appropriately mixes cold air generated through an evaporator and warm air generated by a heater core using a part of the cold air in a housing accommodating an evaporator and a heater core. Thus, air at a desired temperature is blown into the vehicle. As a specific example of such a device, a device described in Patent Document 1 below is known. The air conditioner according to Patent Literature 1 includes, in a casing (air conditioning unit), a cold air passage in which air passing through an evaporator flows, a hot air passage in which air passing through a heater core flows, and cold air and hot air passing through these cold air passages. A mix damper for adjusting the mixing ratio of the warm air that has passed through the passage.

　ところで、近年では車両用空調装置の小型化が進められている。特に小型車ではスペースが限定的であることから、空調装置に対する小型化の要求が大きい。このため、空調ユニット内の容積に制約が生じ、上記の冷風通路、温風通路、及び冷風と温風とを混合させるための空間（エアミックス空間）が従来よりも狭くなる傾向にある。その結果、冷風と温風が十分に混合されずに室内に供給されてしまう場合がある。 By the way, in recent years, miniaturization of vehicle air conditioners has been promoted. In particular, since the space in a small car is limited, there is a great demand for a compact air conditioner. For this reason, the capacity in the air-conditioning unit is restricted, and the space (air mix space) for mixing the cool air passage, the warm air passage, and the cool air and the warm air tends to be smaller than before. As a result, the cool air and the warm air may not be sufficiently mixed and supplied to the room.
　そこで本発明は、設置スペースが小さくとも、適切に車内の温度調節が可能な車両用空調装置を提供する。 Therefore, the present invention provides a vehicle air conditioner that can appropriately control the temperature inside a vehicle even if the installation space is small.
　本発明の第一の態様によれば、車両用空調装置は、空気を冷やすことで冷風を生成するエバポレータと、前記エバポレータの下流側に配置されて前記冷風を温めて温風を生成するヒータコアと、前記エバポレータの上流側に配置されて前記エバポレータに前記空気を供給する空気供給用流路、前記エバポレータの下流側であって前記ヒータコアの上流側に配置されて前記冷風が流れる冷風用流路、前記ヒータコアの下流側に配置されて前記温風が吹き出される温風用流路、及び前記冷風用流路と前記温風用流路とに接続されるとともに前記冷風用流路及び前記温風用流路の下流側に配置されて前記冷風と前記温風が混合されるエアミックス空間を区画する筐体と、前記エアミックス空間に連通する流路を形成するダクトと、前記筐体内で前記ヒータコアと前記エバポレータとの間で、前記冷風用流路と前記エアミックス空間とを接続する冷風連通口と、前記温風用流路と前記エアミックス空間とを接続する温風連通口とにわたって配置され、スライド移動することで前記冷風連通口と前記温風連通口との開度の比を調節するダンパと、前記筐体内の前記ダンパの下流側に、前記筐体とは別部材として設けられ、前記温風用流路から前記ダンパ及び前記エアミックス空間に向かって延び、前記温風の流れる方向に交差する幅方向に互いに離れて配置された複数のフィンを有する案内部材と、を備える。 According to the first aspect of the present invention, an air conditioner for a vehicle includes an evaporator that generates cool air by cooling air, and a heater core that is disposed downstream of the evaporator and heats the cool air to generate hot air. An air supply flow path that is arranged upstream of the evaporator and supplies the air to the evaporator, a cool air flow path that is arranged downstream of the evaporator and upstream of the heater core and through which the cool air flows, A flow path for hot air that is disposed downstream of the heater core and from which the hot air is blown out, and that is connected to the flow path for cold air and the flow path for hot air, and the flow path for cold air and the hot air A casing that is disposed downstream of the air flow path and that defines an air mix space in which the cold air and the hot air are mixed, a duct that forms a flow path that communicates with the air mix space, Between the heater core and the evaporator, a cold air communication port for connecting the cold air flow path and the air mix space, and a hot air communication port for connecting the hot air flow path and the air mix space are arranged. A damper that adjusts the ratio of the degree of opening between the cold air communication port and the hot air communication port by sliding, and the housing is provided as a separate member on the downstream side of the damper in the housing. A guide member having a plurality of fins extending from the flow path for hot air toward the damper and the air mix space and spaced apart from each other in a width direction intersecting a direction in which the hot air flows.
　この構成によれば、車両用空調装置は、複数のフィンを有する案内部材を備えている。複数のフィンは温風用流路からエアミックス空間に向かって延びている。したがって、これらフィンによって冷風及び温風の流れを乱して複雑な流れを生み出すことができる。よって、冷風と温風の混合を促進することができる。さらに複数のフィンは、幅方向から温風を挟むように設けられていることになり、温風がエアミックス空間に向かうにつれて幅方向外側に広がることを抑制でき、温風の流速が増す。その結果、エアミックス空間内を流通する冷風に対する温風の貫通力が増大し、温風が冷風によって吹き飛ばされてしまうことがなくなる。よって温風と冷風とを十分に混合することができる。 According to this configuration, the vehicle air conditioner includes the guide member having the plurality of fins. The plurality of fins extend from the hot air flow path toward the air mix space. Therefore, the fins can disturb the flow of the cool air and the warm air to create a complicated flow. Therefore, mixing of the cool air and the warm air can be promoted. Further, the plurality of fins are provided so as to sandwich the warm air from the width direction, so that the warm air can be prevented from spreading outward in the width direction toward the air mix space, and the flow velocity of the warm air increases. As a result, the penetration force of the warm air to the cool air flowing in the air mix space increases, and the warm air is not blown off by the cool air. Therefore, the warm air and the cool air can be sufficiently mixed.
　また、上記の車両用空調装置では、前記案内部材は、前記幅方向に延びて前記筐体に着脱可能に支持されて、かつ、前記複数のフィンを支持するベース部をさらに有してもよい。 In the above-described air conditioner for a vehicle, the guide member may further include a base portion extending in the width direction, detachably supported by the housing, and supporting the plurality of fins. .
　この構成によれば、案内部材がベース部によって筐体に対して着脱可能に支持されている。これにより、筐体を例えば樹脂による射出成形で形成する場合に、案内部材の形状を考慮することなく金型を製作することができる。さらに、金型による制約を受けないことから、案内部材自体の形状にも自由度を持たせることができる。 According to this configuration, the guide member is detachably supported by the base with respect to the housing. Accordingly, when the housing is formed by, for example, injection molding using a resin, a mold can be manufactured without considering the shape of the guide member. Further, since there is no restriction by the mold, the shape of the guide member itself can be given a degree of freedom.
　また、上記の車両用空調装置では、前記案内部材は、前記幅方向に延びて前記筐体に一体に設けられ、かつ、前記複数のフィンを着脱可能に支持するベース部をさらに有してもよい。 In the above-described vehicle air conditioner, the guide member may further include a base portion that extends in the width direction and is provided integrally with the housing and that detachably supports the plurality of fins. Good.
　この構成によれば、筐体と一体のベース部によって、複数のフィンが筐体に対して着脱可能に設けられている。これにより複数のフィンの形状、設置方向、及び設置位置などを温風の流れに合わせて容易に変更可能である。 According to this configuration, the plurality of fins are detachably provided to the housing by the base integrated with the housing. Thus, the shapes, installation directions, installation positions, and the like of the plurality of fins can be easily changed according to the flow of warm air.
　また、上記の車両用空調装置では、前記複数のフィンのうち少なくとも一つのフィンは、前記ダンパに向かうに従って前記幅方向の一方側に向かって傾斜して延びていてもよい。 In the vehicle air conditioner, at least one of the plurality of fins may be inclined and extend toward one side in the width direction toward the damper.
　この構成によれば、少なくとも一つのフィンがダンパに向かうに従って幅方向の一方側に向かって傾斜して延びている。これにより、フィンに沿って温風を幅方向の一方側に案内することができる。その結果、冷風と温風が入れ替わるような流れとすることができ、温風と冷風との混合を促進することができる。 According to this configuration, at least one fin extends obliquely toward one side in the width direction toward the damper. Thereby, the warm air can be guided to one side in the width direction along the fins. As a result, the flow can be such that the cold air and the hot air are switched, and the mixing of the hot air and the cold air can be promoted.
　また、上記の車両用空調装置では、前記複数のフィンは、前記ダンパに向かうに従って互いに前記幅方向に近接するように傾斜して延びていてもよい。 In the vehicle air conditioner described above, the plurality of fins may be inclined and extend so as to approach each other in the width direction toward the damper.
　この構成によれば、複数のフィンが互いに近接するように傾斜して延びている。これにより、フィン同士の間の空間（流路）が温風の流れの下流側に向かって狭くなっていき、フィン同士の間の空間を通過する温風の流速を高めることができる。その結果、温風と冷風との混合をさらに促進することができる。 According to this configuration, the plurality of fins extend obliquely so as to approach each other. Thereby, the space (flow path) between the fins becomes narrower toward the downstream side of the flow of the warm air, and the flow velocity of the warm air passing through the space between the fins can be increased. As a result, the mixing of the warm air and the cool air can be further promoted.
　また、上記の車両用空調装置では、前記複数のフィンのすべては、前記ダンパに向かうに従って前記幅方向の一方側に向かって傾斜して延びていてもよい。 In the above-described vehicle air conditioner, all of the plurality of fins may be inclined and extend toward one side in the width direction toward the damper.
　この構成によれば、複数のフィンがダンパに向かって互いに同じ方向に傾斜して延びている。これにより、フィンによって温風を円滑に幅方向の一方側に案内することができる。その結果、冷風と温風が入れ替わるような流れとすることができ、温風と冷風との混合を促進することができる。 According to this configuration, the plurality of fins extend obliquely in the same direction toward the damper. Thereby, the warm air can be smoothly guided to one side in the width direction by the fins. As a result, the flow can be such that the cold air and the hot air are switched, and the mixing of the hot air and the cold air can be promoted.
　上記の車両用空調装置によれば、設置スペースが小さくとも、適切に車内の温度調節を行うことが可能である。 According to the vehicle air conditioner described above, the temperature inside the vehicle can be appropriately adjusted even if the installation space is small.

The hot air generated by the heater core 17 is blown out to the hot air flow path 11F. In the following description, a direction crossing (orthogonal to) the flow direction of the warm air may be referred to as a width direction D1. Further, a direction orthogonal to the width direction D1 in a horizontal plane may be referred to as a front-rear direction D2.
　エアミックス空間１１Ｇは、冷風用流路１１Ｄ及び温風用流路１１Ｆの下流に配置されている。スライドダンパ本体１９Ｂ（スライドダンパ１９の構成要素のうちの１つ）が図１に示す位置にある時、エアミックス空間１１Ｇは、上述の冷風連通口５１及び温風連通口５２を介して、冷風用流路１１Ｄ及び温風用流路１１Ｆに連通している。 The air mix space 11G is arranged downstream of the flow path 11D for cold air and the flow path 11F for hot air. When the slide damper main body 19B (one of the components of the slide damper 19) is at the position shown in FIG. 1, the air mix space 11G is cooled by the cool air communication port 51 and the hot air communication port 52 described above.

In the air mix space 11G, cold air and hot air are mixed to generate air at a desired temperature.
　なお、スライドダンパ本体１９Ｂが下方にスライドして、エバポレータ１５からの冷風がヒータコア１７に供給されない状態では、エアミックス空間１１Ｇには、冷風のみが供給される。 In the state where the slide damper body 19B slides downward and cool air from the evaporator 15 is not supplied to the heater core 17, only cool air is supplied to the air mix space 11G.
　ロータリーダンパ２８は、エアミックス空間１１Ｇに配置されている。ロータリーダンパ２８は、デフ及びフェイス用流路１１Ｈの入口の開度、フロントフット用流路（図示省略）、及びリアフット用流路（図示省略）の開度を調節する。ロータリーダンパ２８は、回転軸６０と、回転軸６０とともに回動するダンパ本体６１と、を有する。 The rotary damper 28 is disposed in the air mix space 11G. The rotary damper 28 adjusts the opening degree of the inlet of the differential and face flow paths 11H, the front foot flow path (not shown), and the rear foot flow path (not shown). The rotary damper 28 has a rotating shaft 60 and a damper main body 61 that rotates with the rotating shaft 60.
　デフ及びフェイス用流路１１Ｈは、エアミックス空間１１Ｇの上方に配置されている。ロータリーダンパ２８が図１に示す位置にある状態では、デフ及びフェイス用流路１１Ｈは、エアミックス空間１１Ｇに連通している。この状態において、デフ及びフェイス用流路１１Ｈには、エアミックス空間１１Ｇを通過した空気が供給される。なお、ロータリーダンパ２８がデフ及びフェイス用流路１１Ｈの入口を塞いだ場合には、デフ及びフェイス用流路１１Ｈには、エアミックス空間１１Ｇを通過した空気は供給されない。 The differential and face channels 11H are arranged above the air mix space 11G. When the rotary damper 28 is at the position shown in FIG. 1, the differential and face flow paths 11H communicate with the air mix space 11G. In this state, the air that has passed through the air mix space 11G is supplied to the differential and face channels 11H. When the rotary damper 28 blocks the inlet of the differential and face flow path 11H, the air that has passed through the air mix space 11G is not supplied to the differential and face flow path 11H.
　フェイス吹出口１１Ｉは、デフ及びフェイス用流路１１Ｈの下流に配置されており、デフ及びフェイス用流路１１Ｈに連通している。 The face outlet 11I is disposed downstream of the differential and face flow paths 11H, and communicates with the differential and face flow paths 11H.

The differential outlet 11L is arranged closer to the blower 13 than the face outlet 11I.
　送風機１３は、送風機収容空間１１Ａに配置されている。送風機１３は、空気供給用流路１１Ｂに空気を供給する。エバポレータ１５は、エバポレータ収容空間１１Ｃに配置されている。エバポレータ１５は、送風機１３から供給された空気を冷やすことで冷風を生成する。生成された冷風は、冷風用流路１１Ｄを流れる。 風 The blower 13 is arranged in the blower housing space 11A. The blower 13 supplies air to the air supply channel 11B. The evaporator 15 is arranged in the evaporator accommodation space 11C. The evaporator 15 generates cool air by cooling the air supplied from the blower 13. The generated cool air flows through the cool air flow path 11D.

When cool air is supplied from the evaporator 15, the heater core 17 generates warm air by warming the cool air. The generated hot air flows through the hot air flow path 11F.
　スライドダンパ１９は、エバポレータ１５とヒータコア１７との間に配置されている。スライドダンパ１９は、回転軸１９Ａと、スライドダンパ本体１９Ｂと、を有する。回転軸１９Ａは、軸線回りに回動可能なギアである。回転軸１９Ａの周方向には、複数の歯が形成されている。 The slide damper 19 is disposed between the evaporator 15 and the heater core 17.

A plurality of teeth are formed in the circumferential direction of the rotation shaft 19A.
　スライドダンパ本体１９Ｂは、回転軸１９Ａよりもヒータコア１７側に配置されている。スライドダンパ本体１９Ｂは、回転軸１９Ａの歯と係合するラックギアを有する。図１に示す状態において、回転軸１９Ａが右回りに回転すると、スライドダンパ本体１９Ｂは、下方にスライド（移動）する。その結果、冷風連通口５１が温風連通口５２よりも大きく開放された状態となる。一方、回転軸１９Ａが左回りに回転すると、スライドダンパ本体１９Ｂは、上方にスライド（移動）する。その結果、温風連通口５２が冷風連通口５１よりも大きく開放された状態となる。即ち、スライドダンパ１９は、スライド移動することで冷風連通口５１と温風連通口５２との開度の比を調節する。 The slide damper body 19B is disposed closer to the heater core 17 than the rotation shaft 19A. The slide damper body 19B has a rack gear that engages with the teeth of the rotation shaft 19A. In the state shown in FIG. 1, when the rotation shaft 19A rotates clockwise, the slide damper body 19B slides (moves) downward. As a result, the cold air communication port 51 is opened more than the hot air communication port 52. On the other hand, when the rotation shaft 19A rotates counterclockwise, the slide damper body 19B slides (moves) upward. As a result, the hot air communication port 52 is opened to a greater extent than the cold air communication port 51. That is, the slide damper 19 adjusts the ratio of the opening degree between the cool air communication port 51 and the hot air communication port 52 by sliding.
　デフ及びフェイス用ダンパ３１は、フェイス吹出口１１Ｉ、及びデフ吹出口１１Ｌとの間に位置する筐体１１の内側に回動可能な状態で設けられている。デフ及びフェイス用ダンパ３１は、フェイス吹出口１１Ｉ、及びデフ吹出口１１Ｌの開度を調節するためのダンパである。 The differential and face damper 31 is rotatably provided inside the housing 11 located between the face outlet 11I and the differential outlet 11L. The differential and face damper 31 is a damper for adjusting the opening of the face outlet 11I and the differential outlet 11L.
　案内部材４０は、温風用流路の下流側に配置されている。案内部材４０は、温風用流路から流れ出た温風を整流するために設けられている。案内部材４０は、ベース部４１と、複数のフィン４２と、を有している。 The guide member 40 is arranged on the downstream side of the flow path for hot air. The guide member 40 is provided for rectifying the hot air flowing out of the hot air flow path. The guide member 40 has a base 41 and a plurality of fins 42.
　ベース部４１は、ヒータコア１７の上端部からわずかに上方に離間して配置された板状の部材である。図２に示すように、ベース部４１は、前後方向Ｄ２他方側に設けられた第一支持部４１Ａと、前後方向Ｄ２一方側に設けられた第二支持部４１Ｃと、これら第一支持部４１Ａ及び第二支持部４１Ｃの間に前後方向Ｄ２にわたって延びるベース部本体４１Ｂと、を有している。第一支持部４１Ａは、上方から下方に向かうに従って、前後方向Ｄ２における寸法が次第に小さくなることで、断面が三角形状をなしている。第二支持部４１Ｃは、下方から上方に向かうに従って、前後方向Ｄ２における寸法が次第に小さくなることで、断面が三角形状をなしている。 The base portion 41 is a plate-like member that is disposed slightly above the upper end of the heater core 17 and is spaced apart from the upper end. As shown in FIG. 2, the base portion 41 includes a first support portion 41A provided on the other side in the front-rear direction D2, a second support portion 41C provided on one side in the front-rear direction D2, and a first support portion 41A. And a base portion main body 41B extending in the front-rear direction D2 between the second support portion 41C and the second support portion 41C. The cross section of the first support portion 41A has a triangular shape as the dimension in the front-rear direction D2 gradually decreases from the upper side to the lower side. The cross section of the second support portion 41C has a triangular shape as the dimension in the front-rear direction D2 gradually decreases from the lower side to the upper side.
　第一支持部４１Ａには、幅方向Ｄ１に沿って延びるピン４１Ｄが設けられている。第二支持部４１Ｃには、同様に幅方向Ｄ１に沿って延びるピン４１Ｅが設けられている。筐体１１の内面に形成された穴（不図示）にこれらピン４１Ｄ，４１Ｅを挿入することで、案内部材４０が筐体１１内で着脱可能に支持される。ベース部本体４１Ｂの一方側の面は、エアミックス空間１１Ｇを向いている。一方で、ベース部本体４１Ｂの他方側の面は、ヒータコア１７側を向いている。 (4) The first support portion 41A is provided with a pin 41D extending along the width direction D1. Similarly, a pin 41E extending along the width direction D1 is provided on the second support portion 41C. By inserting these pins 41D and 41E into holes (not shown) formed on the inner surface of the housing 11, the guide member 40 is detachably supported inside the housing 11. One surface of the base portion main body 41B faces the air mix space 11G. On the other hand, the other surface of the base body 41B faces the heater core 17 side.
　図１、及び図２に示すように、ベース部４１（ベース部本体４１Ｂ）の一方側の面上には、複数のフィン４２が一体に設けられている。各フィン４２は、ベース部４１からエアミックス空間１１Ｇ側（上側）及びスライドダンパ１９側（前側）に向かって突出する矩形板状をなす。ただしフィン４２の形状は矩形には限定されない。本実施形態では、各フィン４２の突出高さは、温風用流路側からヒータコア収容空間側に向かうに従って次第に大きくなっている。さらに、図２に示すように、スライドダンパ本体１９Ｂが最も下方にある状態（即ち、温風用流路１１Ｆがスライドダンパ本体１９Ｂによって閉塞されている状態）において、各フィン４２はスライドダンパ本体１９Ｂの上端部の高さ（図２中の鎖線で示す位置）よりもわずかに上方に突出している。即ち、各フィン４２の上端は、エアミックス空間１１Ｇの下方の冷風連通口５１の中途の高さの位置に配置されている。よって各フィン４２は冷風連通口５１を高さ方向の全域で遮ることがなく、高さ方向の一部のみで遮るように設けられている。また、各フィン４２の前方の端部は冷風連通口５１に対して後方に離れた位置に配置されている。 As shown in FIGS. 1 and 2, a plurality of fins 42 are integrally provided on one surface of the base portion 41 (base portion main body 41B). Each fin 42 has a rectangular plate shape protruding from the base portion 41 toward the air mix space 11G (upper side) and the slide damper 19 side (front side). However, the shape of the fin 42 is not limited to a rectangle. In the present embodiment, the protruding height of each fin 42 gradually increases from the hot air flow path side toward the heater core housing space side. Further, as shown in FIG. 2, in a state where the slide damper main body 19B is at the lowest position (that is, a state in which the hot air passage 11F is closed by the slide damper main body 19B), each fin 42 is connected to the slide damper main body 19B. Protrudes slightly higher than the height of the upper end (the position indicated by the chain line in FIG. 2). That is, the upper end of each fin 42 is disposed at a position at a halfway height of the cool air communication port 51 below the air mix space 11G. Therefore, each fin 42 is provided so as not to block the cool air communication port 51 in the whole area in the height direction, but to block only a part in the height direction. The front end of each fin 42 is disposed at a position away from the cold air communication port 51 rearward.
　図３に示すように、本実施形態に係る案内部材４０は、４つのフィン４２を有している。これら４つのフィン４２は、幅方向Ｄ１に間隔をあけて配列されている。幅方向Ｄ１における一方側に位置する２つのフィン４２は、前後方向Ｄ２の一方側から他方側（即ち、スライドダンパ１９側）に向かうに従って、幅方向Ｄ１の一方側から他方側に向かって傾斜して延びている。幅方向Ｄ１における他方側に位置する２つのフィン４２は、前後方向Ｄ２の一方側から他方側に向かうに従って、幅方向Ｄ１の他方側から一方側に向かって傾斜して延びている。言い換えると、一対ずつのフィン４２が、前後方向Ｄ２一方側から他方側に向かうに従って次第に近接するように配置されている。 案 内 As shown in FIG. 3, the guide member 40 according to the present embodiment has four fins. These four fins 42 are arranged at intervals in the width direction D1. The two fins 42 located on one side in the width direction D1 are inclined from one side in the width direction D1 to the other side from one side in the front-rear direction D2 to the other side (that is, the slide damper 19 side). Extending. The two fins 42 located on the other side in the width direction D1 are inclined and extend from one side to the other side in the width direction D1 as going from one side to the other side in the front-rear direction D2. In other words, the pair of fins 42 are arranged so as to gradually approach from one side in the front-rear direction D2 to the other side.
　本実施形態では、案内部材４０は筐体１１に対して別部材として形成されている。即ち、案内部材４０は、筐体１１に着脱可能に取り付けられている。上記の説明では複数のフィン４２がベース部４１に対して一体に形成されている例について説明した。しかしながら、各フィン４２のみを、筐体１１に一体に設けられたベース部４１に対して着脱可能とすることも可能であるし、筐体１１に対してベース部４１が着脱可能であり、かつ、ベース部４１に対してフィン４２も着脱可能であってもよい。 In the present embodiment, the guide member 40 is formed as a separate member from the housing 11. That is, the guide member 40 is detachably attached to the housing 11. In the above description, the example in which the plurality of fins 42 are formed integrally with the base portion 41 has been described. However, it is also possible to make only each of the fins 42 detachable with respect to the base 41 provided integrally with the housing 11, or to attach and detach the base 41 to and from the housing 11, and The fins 42 may be detachable from the base 41.
　続いて、本実施形態に係る車両用空調装置１０の動作について説明する。車両用空調装置１０を運転するに当たっては、まず送風機１３を稼動させる。送風機１３の稼動に伴って、空気供給用流路１１Ｂを空気が流通する。空気供給用流路１１Ｂを通過した空気は、エバポレータ１５に接触することで熱交換されて冷風となり、冷風用流路１１Ｄに流れ込む。スライドダンパ本体１９Ｂが図１に示す位置にある状態では、冷風用流路１１Ｄに流れ込んだ空気の一部は、スライドダンパ本体１９Ｂの下方（温風連通口５２）を通過してヒータコア収容空間１１Ｅに流れ込む。ヒータコア収容空間１１Ｅに流れ込んだ空気は、ヒータコア１７に接触することで熱交換されて温風となる。この温風は、温風用流路１１Ｆを通じて上述のエアミックス空間１１Ｇに向かう。一方で、冷風用流路１１Ｄに流れ込んだ空気の残余の成分は、スライドダンパ本体１９Ｂの上方（冷風連通口５１）を通過してエアミックス空間１１Ｇに向かう。即ち、エアミックス空間１１Ｇでは、冷風と温風とが、スライドダンパ本体１９Ｂの位置に応じた割合で混合される。 Next, the operation of the vehicle air conditioner 10 according to the present embodiment will be described. In operating the vehicle air conditioner 10, the blower 13 is first operated. With the operation of the blower 13, air flows through the air supply channel 11B. The air that has passed through the air supply flow path 11B contacts the evaporator 15 and exchanges heat to become cool air, and flows into the cool air flow path 11D. When the slide damper main body 19B is in the position shown in FIG. 1, a part of the air flowing into the cold air flow path 11D passes below the slide damper main body 19B (the hot air communication port 52) and the heater core housing space 11E. Flow into The air that has flowed into the heater core housing space 11 </ b> E contacts the heater core 17 and undergoes heat exchange to become hot air. This warm air goes to the above-mentioned air mix space 11G through the warm air flow path 11F. On the other hand, the remaining components of the air that has flowed into the cool air flow passage 11D pass above the slide damper body 19B (the cool air communication port 51) and head toward the air mix space 11G. That is, in the air mix space 11G, the cool air and the hot air are mixed at a ratio according to the position of the slide damper body 19B.
　ここで、近年では空調装置の小型化が進められている。特に小型車ではスペースが限定的であることから、空調装置に対する小型化の要求が大きい。このため、空調ユニット内の容積に制約が生じ、上記の冷風用流路１１Ｄ、温風用流路１１Ｆ、及び冷風と温風とを混合させるための空間（エアミックス空間１１Ｇ）が従来よりも狭くなる傾向にある。その結果、冷風と温風が十分に混合されずに室内に供給されてしまう場合がある。 Here, in recent years, miniaturization of air conditioners has been promoted. In particular, since the space in a small car is limited, there is a great demand for a compact air conditioner. For this reason, the capacity in the air-conditioning unit is restricted, and the above-described flow path for cold air 11D, flow path for hot air 11F, and a space for mixing cold air and hot air (air mixing space 11G) are larger than before. It tends to be narrow. As a result, the cool air and the warm air may not be sufficiently mixed and supplied to the room.
　特に、上記の車両用空調装置において、冷風は冷風用流路１１Ｄから直接エアミックス空間１１Ｇに到達するのに対して、温風は冷風用流路１１Ｄ、ヒータコア１７、及び温風用流路１１Ｆを通じてエアミックス空間１１Ｇに到達する。つまり、冷風流路１１Ｄに比べ温風流路１１Ｆは、流路の圧力損失が大きい為、温風の流速が低下してしまう可能性がある。温風の流速が低下すると、エアミックス空間１１Ｇで冷風と混合される際に、相対的に高速である冷風によって温風が吹き飛ばされ、両者が十分に混合されなくなってしまう。その結果、精緻な温度調節に困難が生じる可能性がある。 In particular, in the above-described vehicle air conditioner, the cool air directly reaches the air mixing space 11G from the cool air flow passage 11D, whereas the warm air flows through the cool air flow passage 11D, the heater core 17, and the hot air flow passage 11F. And reaches the air mix space 11G. In other words, the flow velocity of the hot air may be reduced in the hot air flow path 11F since the pressure loss in the flow path is larger in the hot air flow path 11F than in the cold air flow path 11D. If the flow velocity of the warm air is reduced, the warm air is blown off by the relatively high-speed cool air when mixed with the cool air in the air mixing space 11G, and the two are not sufficiently mixed. As a result, it may be difficult to perform precise temperature control.
　しかしながら、本実施形態に係る車両用空調装置では、温風用流路１１Ｆの下流側に、複数のフィン４２を有する案内部材４０が設けられている。複数のフィン４２は、温風用流路からエアミックス空間に向かって延びている。したがって、これらフィン４２によって冷風及び温風の流れを乱して複雑な流れを生み出すことができる。よって、冷風と温風の混合を促進することができる。さらに複数のフィン４２が幅方向Ｄ１から温風を挟むように設けられていることで、温風がエアミックス空間１１Ｇに向かうにつれて幅方向Ｄ１外側に広がることを抑制でき、温風の流速が増す。その結果、エアミックス空間内を流通する冷風に対する温風の貫通力が増大し、温風が冷風によって吹き飛ばされてしまうことがなくなる。よって温風と冷風とを十分に混合することができる。 However, in the vehicle air conditioner according to the present embodiment, the guide member 40 having the plurality of fins 42 is provided on the downstream side of the hot air flow path 11F. The plurality of fins 42 extend from the hot air flow path toward the air mix space. Therefore, the fins 42 can disturb the flow of the cool air and the warm air to create a complicated flow. Therefore, mixing of the cool air and the warm air can be promoted. Further, since the plurality of fins 42 are provided so as to sandwich the warm air from the width direction D1, it is possible to suppress the warm air from spreading outward in the width direction D1 toward the air mix space 11G, and the flow velocity of the warm air is increased. . As a result, the penetration force of the warm air to the cool air flowing in the air mix space increases, and the warm air is not blown off by the cool air. Therefore, the warm air and the cool air can be sufficiently mixed.
　さらに、上記の構成によれば、案内部材４０がベース部４１によって筐体１１に対して着脱可能に支持されている。これにより、筐体１１を例えば樹脂による射出成形で形成する場合に、案内部材４０の形状を考慮することなく金型を製作することができる。さらに、案内部材４０を着脱可能な構成としたことから、案内部材４０自体の形状にも自由度を持たせることができる。 According to the above configuration, the guide member 40 is detachably supported by the base portion 41 with respect to the housing 11. Accordingly, when the housing 11 is formed by, for example, injection molding using a resin, a mold can be manufactured without considering the shape of the guide member 40. Further, since the guide member 40 is configured to be detachable, the shape of the guide member 40 itself can be given a degree of freedom.
　加えて上述したように筐体１１と一体のベース部４１と着脱可能に複数のフィン４２が設けられていることで複数のフィン４２が筐体１１に対して着脱可能に設けられている場合には、複数のフィン４２の形状、設置方向、及び設置位置などを温風の流れに合わせて容易に変更可能である。 In addition, as described above, since the plurality of fins 42 are detachably provided to the base portion 41 integrated with the housing 11, the plurality of fins 42 are detachably provided to the housing 11. Can easily change the shape, installation direction, and installation position of the plurality of fins 42 in accordance with the flow of warm air.
　さらに、上記の構成によれば、複数のフィン４２が互いに近接するように傾斜して延びている。これにより、フィン４２同士の間の空間（流路）が温風の流れの下流側に向かって狭くなっていき、フィン４２同士の間の空間を通過する温風の流速を高めることができる。その結果、温風と冷風との混合をさらに促進することができる。 {Furthermore, according to the above configuration, the plurality of fins 42 extend obliquely so as to approach each other. As a result, the space (flow path) between the fins 42 becomes narrower toward the downstream side of the flow of the warm air, and the flow velocity of the warm air passing through the space between the fins 42 can be increased. As a result, the mixing of the warm air and the cool air can be further promoted.
　さらに、上記の構成によれば、各フィン４２の上端を、エアミックス空間１１Ｇの下方の冷風連通口５１の中途の高さ位置に配置した構成とすることにより、冷風連通口５１の上部における冷風連通口５１付近の領域で、冷風が各フィン４２に干渉してしまうことを最小限に抑制でき、この領域での冷風の好適な流通を確保することができる。これにより、特に最大冷房運転時（冷風連通口５１の開度が最大になっている時）の騒音及び振動が抑制されるとともに圧力損失の増大による装置全体の効率低下が抑制される。また、各フィン４２の前方の端部は冷風連通口５１に対して後方に離れた位置に配置されているため、冷風の流通を大きく妨げることがない。 Further, according to the above configuration, the upper end of each fin 42 is arranged at a halfway position of the cool air communication port 51 below the air mix space 11G, so that the cool air in the upper part of the cool air communication port 51 is formed. In the area near the communication port 51, it is possible to minimize the interference of the cool air with each fin 42, and it is possible to secure a suitable flow of the cool air in this area. This suppresses noise and vibration, especially during the maximum cooling operation (when the opening of the cool air communication port 51 is at a maximum), and also suppresses a decrease in efficiency of the entire apparatus due to an increase in pressure loss. In addition, the front end of each fin 42 is located at a position away from the cool air communication port 51 rearward, so that the flow of the cool air is not largely obstructed.
　以上、本発明の第一実施形態について説明した。なお、本発明の要旨を逸脱しない限りにおいて、上記の構成に種々の変更や改修を施すことが可能である。例えば、上記実施形態では、案内部材４０のフィン４２の数が４つである例について説明した。しかしながら、フィン４２の数は４つに限定されず、仕様や設計に応じて適宜に変更することが可能である。例えば図４に示すように、２つのみのフィン４２を設けることも可能である。 The first embodiment of the present invention has been described above. Note that various changes and modifications can be made to the above configuration without departing from the spirit of the present invention. For example, in the above embodiment, an example in which the number of the fins 42 of the guide member 40 is four has been described. However, the number of the fins 42 is not limited to four, and can be appropriately changed according to specifications and designs. For example, as shown in FIG. 4, only two fins 42 can be provided.
［第二実施形態］
　次に、本発明の第二実施形態について、図５を参照して説明する。なお、上記第一実施形態と同様の構成については同一の符号を付し、詳細な説明を省略する。図５に示すように、本実施形態では、案内部材４０が２つのみのフィン４２Ｂを有し、かつ、これらフィン４２Ｂが互いに同一の方向に向かって延びている。具体的には、各フィン４２Ｂは、前後方向Ｄ２一方側から他方側に向かうに従って、幅方向Ｄ１他方側から一方側に向かって傾斜して延びている。各フィン４２Ｂは互いに同じ方向に傾斜して延びていればよく、互いに平行に延びていていもよいし、互いに幅方向Ｄ１に対する傾斜角度が異なっていてもよい。 [Second embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. As shown in FIG. 5, in the present embodiment, the guide member 40 has only two fins 42B, and these fins 42B extend in the same direction. Specifically, each fin 42B is inclined and extends from the other side to the one side in the width direction D1 as going from one side to the other side in the front-rear direction D2. The fins 42B only need to extend in the same direction and may extend in parallel with each other, or may have different inclination angles with respect to the width direction D1.
　この構成によれば、複数のフィン４２Ｂがスライドダンパ１９に向かって互いに同じ方向に傾斜して延びている。これにより、フィン４２Ｂによって温風を円滑に幅方向Ｄ１の一方側に案内することができる。その結果、冷風と温風が入れ替わるような流れとすることができ、温風と冷風との混合を促進することができる。 According to this configuration, the plurality of fins 42B extend obliquely in the same direction toward the slide damper 19. Thereby, the warm air can be smoothly guided to one side in the width direction D1 by the fins 42B. As a result, the flow can be such that the cold air and the hot air are switched, and the mixing of the hot air and the cold air can be promoted.
　以上、本発明の第二実施形態について説明した。なお、本発明の要旨を逸脱しない限りにおいて、上記の構成に種々の変更や改修を施すことが可能である。例えば、上記実施形態では、案内部材４０のフィン４２Ｂの数が２つである例について説明した。しかしながら、フィン４２Ｂの数は２つに限定されず、仕様や設計に応じて適宜に変更することが可能である。また、フィン４２Ｂは、上述の場合とは逆に前後方向Ｄ２一方側から他方側に向かうに従って、幅方向Ｄ１一方側から他方側に向かって傾斜して延びていてもよい。 The second embodiment of the present invention has been described above. Note that various changes and modifications can be made to the above configuration without departing from the spirit of the present invention. For example, in the above embodiment, an example in which the number of the fins 42B of the guide member 40 is two has been described. However, the number of the fins 42B is not limited to two, and can be appropriately changed according to specifications and design. Further, the fins 42B may be inclined and extend from one side to the other side in the width direction D1 as going from one side in the front-rear direction D2 to the other side, contrary to the above-described case.
［第三実施形態］
　続いて、本発明の第四実施形態について、図６を参照して説明する。なお、上記の各実施形態と同様の構成については同一の符号を付し、詳細な説明を省略する。図６に示すように、案内部材４０が２つのみのフィン４２Ｃ，４２Ｄを有し、これらフィン４２Ｃ，４２Ｄが互いに異なる方向に延びている。幅方向Ｄ１他方側に位置するフィン４２Ｃは、前後方向Ｄ２一方側から他方側に向かうに従って幅方向Ｄ１他方側から一方側に向かって延びている。一方で、幅方向Ｄ１一方側に位置するフィン４２Ｄは、前後方向Ｄ２に延びている。 [Third embodiment]
Subsequently, a fourth embodiment of the present invention will be described with reference to FIG. The same components as those in the above embodiments are denoted by the same reference numerals, and detailed description will be omitted. As shown in FIG. 6, the guide member 40 has only two fins 42C and 42D, and these fins 42C and 42D extend in different directions. The fin 42C located on the other side in the width direction D1 extends from the other side in the width direction D1 to one side as going from one side in the front-rear direction D2 to the other side. On the other hand, the fin 42D located on one side in the width direction D1 extends in the front-rear direction D2.
　この構成によれば、複数のフィン４２Ｃ，４２Ｄがダンパに向かって互いに同一の方向に延びている。これにより、温風を円滑に案内することができる。さらに、２つのフィン４２Ｃ，４２Ｄが前後方向Ｄ２他方側に向かうに従って次第に近接するように配列されているため、温風の流速を増加させることができる。その結果、温風と冷風との混合を促進することができる。 According to this configuration, the plurality of fins 42C and 42D extend in the same direction toward the damper. Thereby, warm air can be guided smoothly. Furthermore, since the two fins 42C and 42D are arranged so as to gradually approach each other in the front-rear direction D2, the flow velocity of the warm air can be increased. As a result, mixing of the warm air and the cool air can be promoted.
　以上、本発明の第三実施形態について説明した。なお、本発明の要旨を逸脱しない限りにおいて、上記の構成に種々の変更や改修を施すことが可能である。例えば、上記実施形態では、案内部材４０のフィン４２Ｃ，４２Ｄの数が２つである例について説明した。しかしながら、フィン４２Ｃ，４２Ｄの数は２つに限定されず、仕様や設計に応じて適宜に変更することが可能である。 The third embodiment of the present invention has been described above. Note that various changes and modifications can be made to the above configuration without departing from the spirit of the present invention.
