Abstract

<P>PROBLEM TO BE SOLVED: To prevent water from splashing from an evaporator 20 by reducing deviation of an airflow passing through the evaporator 20 when a distance between a blower 2 and the evaporator 20 is small. <P>SOLUTION: An airflow diffusion means 34 for diffusing the airflow from the blower 2 is installed to a passage enlarging part K between the blower 2 and the evaporator 20, so that the air for air-conditioning passes through the entire ventilation face of the evaporator 20 approximately constantly. Splash of the water diffuses the airflow from a large airflow volume portion to a small volume portion and makes a passing wind speed of the evaporator 20 constant by installing the airflow diffusion means 34 to the passage enlarging part K, focusing attention on that it occurs due to inconstant distribution of the wind speed at the passage enlarging part K. Even when the distance between the blower 2 and the evaporator 20 is small, deviation of the airflow passing through the evaporator 20 is reduced by the airflow diffusion means 34 installed to the passage enlarging part K, so as to prevent water from splashing from the evaporator 20. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、空気を冷却して空調を行う車両用空調装置に関するものであり、特に、エバポレータ（冷却用熱交換器）に付着した凝縮水が空調風に乗って飛散する水飛びを防止する技術に関するものである。   TECHNICAL FIELD The present invention relates to a vehicle air conditioner that cools air and performs air conditioning, and in particular, a technique for preventing water splashes in which condensed water adhering to an evaporator (cooling heat exchanger) is scattered on air conditioned air. It is about.

従来、この種の車両用空調装置において、空気を冷却することによってエバポレータの表面に発生する凝縮水は、エバポレータのコア表面を伝って自重で下方へ流れ落ち、エバポレータ下部の空調ケースに形成されたドレインポートから車外に排水されるようになっている。   Conventionally, in this type of vehicle air conditioner, the condensed water generated on the surface of the evaporator by cooling the air flows down along the core surface of the evaporator under its own weight and is formed in the air conditioning case below the evaporator. It drains out of the car from the port.

エバポレータの凝縮水に関する従来技術として、本出願人は先に特許文献１に示す技術を開示している。これは、エバポレータ上流側の空調ケース内に、流れる空気を絞って風速を増加させる絞り手段を設け、空調停止時に絞り手段によって作られる噴流をエバポレータの上流側の端面に沿って移動させることにより、エバポレータに付着した凝縮水を吹き飛ばすものである。   As a prior art regarding the condensed water of the evaporator, the present applicant has previously disclosed the technique disclosed in Patent Document 1. This is because in the air conditioning case on the upstream side of the evaporator, a throttle means for restricting the flowing air and increasing the wind speed is provided, and the jet flow created by the throttle means when the air conditioning is stopped is moved along the upstream end face of the evaporator. The condensed water adhering to the evaporator is blown away.

また、特許文献２に開示されたものは、縦型一体式空調装置において、エバポレータ上流側の空調ダクト内に平面部を設け、空気流をその平面部に当てて流入させることにより、エバポレータを通過する空気流の偏りを軽減すると共に、エバポレータへの凝縮水の跳ね上げを防止したものである。
特開平７−１１７４５７号公報 特開２００３−７２３４３号公報 Moreover, what was disclosed by patent document 2 is a vertical integrated air conditioner. A flat part is provided in the air conditioning duct on the upstream side of the evaporator, and the air flow is applied to the flat part to flow through the evaporator. As well as alleviating the bias of the air flow, it prevents the condensed water from jumping up to the evaporator.
Japanese Unexamined Patent Publication No. 7-117457 JP 2003-72343 A

送風機（送風手段）とエバポレータとの間に距離が取れる車両用空調装置では、送風機とエバポレータとの間の通路拡大部が緩やかであり、この通路拡大部内で風速分布が均一化されるため、エバポレータで発生した結露水はコア表面を伝って自重で下方へ流れ落ちて正常に排出され、エバポレータから下流への水飛びは生じにくい。   In the vehicle air conditioner that can take a distance between the blower (blower means) and the evaporator, the passage enlarged portion between the blower and the evaporator is gentle, and the wind speed distribution is made uniform in the passage enlarged portion. Condensed water generated in the above flow along the core surface and flow downward under its own weight and is normally discharged, and it is difficult for water to flow downstream from the evaporator.

図６（ａ）は従来の車両用空調ユニット１での問題と対応を説明する模式図であり、（ｂ）はエバポレータ２０下流の風速分布を示す部分模式図である。しかしながら、車両用空調装置１の小型化傾向に伴い、図６（ａ）に示すように送風機２とエバポレータ２０との間に距離が取れなくなってきており、通路拡大部Ｋが急になることより送風機２からの風速分布が均一にならないまま送風空気がエバポレータ２０を通過し（図６（ｂ）参照）、風速の高い部分からは水飛びが発生するという問題が生じている。   FIG. 6A is a schematic diagram for explaining problems and countermeasures in the conventional vehicle air conditioning unit 1, and FIG. 6B is a partial schematic diagram showing the wind speed distribution downstream of the evaporator 20. However, as the vehicle air-conditioning apparatus 1 is downsized, the distance between the blower 2 and the evaporator 20 cannot be secured as shown in FIG. 6A, and the passage enlargement portion K becomes steep. There is a problem that blown air passes through the evaporator 20 without uniforming the wind speed distribution from the blower 2 (see FIG. 6B), and water jumps from a portion with a high wind speed.

水飛びで飛散した水滴Ｓは、そのまま車室内吹出口より乗員へ飛散したり、後流のヒータコア２５で加熱されて蒸気となって車室内へ吹き出され、車両窓ガラスで窓曇りを生じさせたりという不具合を生じる。このエバポレータ２０からの水飛び対策として、エバポレータ２０の水飛び部分にネットＮを設けて飛んだ水滴Ｓを捕集してドレインポート２３へと流し、下流への飛散を防止する方法が周知であるがコストアップとなる。   The water droplets S scattered by the water splash are directly scattered from the vehicle interior outlet to the occupant, or heated by the downstream heater core 25 to be blown into the vehicle interior, thereby causing window fog on the vehicle window glass. This causes a malfunction. As a countermeasure against water splashing from the evaporator 20, a method is known in which a net N is provided in the water jumping portion of the evaporator 20 to collect the flying water droplets S and flow to the drain port 23 to prevent scattering downstream. Increases costs.

本発明は、上記従来の問題点に鑑みて成されたものであり、その目的は、送風機とエバポレータとの間に距離が取れない場合において、エバポレータを通過する空気流の偏りを軽減してエバポレータからの水飛びを防止することのできる車両用空調装置を提供することにある。   The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to reduce the deviation of the air flow passing through the evaporator when the distance between the blower and the evaporator cannot be secured. It is in providing the vehicle air conditioner which can prevent the water jump from.

本発明は上記目的を達成するために、請求項１ないし請求項６に記載の技術的手段を採用する。すなわち、請求項１に記載の発明では、空調空気の通路を成す車両用空調ユニット（１）と、車両用空調ユニット（１）内に空調用空気を送風する送風手段（２）と、車両用空調ユニット（１）内に配置されて空調用空気を冷却する冷却用熱交換器（２０）とを備えた車両用空調装置において、
送風手段（２）と冷却用熱交換器（２０）との間の通路拡大部（Ｋ）に、送風手段（２）からの空気流を拡散させる空気流拡散手段（３４）を設けて空調用空気が冷却用熱交換器（２０）の全通風面を略均等に通過するようにしたことを特徴としている。 In order to achieve the above object, the present invention employs technical means described in claims 1 to 6. That is, according to the first aspect of the present invention, the vehicle air conditioning unit (1) that forms a passage for the conditioned air, the air blowing means (2) that blows the air for air conditioning into the vehicle air conditioning unit (1), and the vehicle In a vehicle air conditioner provided with a cooling heat exchanger (20) arranged in the air conditioning unit (1) for cooling air conditioning air,

It is characterized in that air passes substantially uniformly through the entire ventilation surface of the cooling heat exchanger (20).

冷却用熱交換器（２０）からの水飛びは、送風手段（２）と冷却用熱交換器（２０）間の通路拡大部（Ｋ）での風速分布の不均一が原因で発生する点に着目し、送風手段（２）後の通路拡大部（Ｋ）に空気流拡散手段（３４）を設けて通風量の多い部分から少ない部分へ空気流を拡散させ、冷却用熱交換器（２０）の通過風速を均一にするものである。   Water splashing from the cooling heat exchanger (20) occurs due to non-uniformity of the wind speed distribution in the passage expansion section (K) between the air blowing means (2) and the cooling heat exchanger (20). Paying attention, air flow diffusing means (34) is provided in the passage enlargement part (K) after the air blowing means (2) to diffuse the air flow from the part with a large amount of air flow to the part with a small air flow, and the heat exchanger for cooling (20) This makes the passing wind speed uniform.

この請求項１に記載の発明によれば、送風手段（２）と冷却用熱交換器（２０）との間に距離が取れない場合においても、通路拡大部（Ｋ）に空気流拡散手段（３４）を設けることにより、送風手段（２）から送風された風が空気流拡散手段（３４）によって拡散されて均一化され、冷却用熱交換器（２０）を通過する空気流の偏りが軽減（風速の高い部分が低減）されるようになる。   According to the first aspect of the present invention, even when the distance between the air blowing means (2) and the cooling heat exchanger (20) cannot be secured, the air flow diffusion means ( 34), the air blown from the blowing means (2) is diffused and uniformed by the air flow diffusing means (34), and the deviation of the air flow passing through the cooling heat exchanger (20) is reduced. (High wind speed is reduced).

このため、冷却用熱交換器（２０）での冷却により結露した水は、冷却用熱交換器（２０）のコア表面を伝って自重で流れ落ちて冷却用熱交換器（２０）下方に設けられたドレインポート（２３）から車外に正常に排水され、冷却用熱交換器（２０）からの水飛びを防止することができる。尚、この空気流拡散手段（３４）は、車両用空調ユニット（１）の外殻を形成する空調ケース（２１）に一体に形成しても良いし、別体を組み付ける構成であっても良い。   For this reason, the water condensed by cooling in the cooling heat exchanger (20) flows down by its own weight along the core surface of the cooling heat exchanger (20) and is provided below the cooling heat exchanger (20). Then, the water is normally drained from the drain port (23) to the outside of the vehicle, and water splash from the cooling heat exchanger (20) can be prevented. The air flow diffusing means (34) may be formed integrally with the air conditioning case (21) forming the outer shell of the vehicle air conditioning unit (1), or may be configured to be assembled separately. .

また、請求項２に記載の発明では、空気流拡散手段（３４）として、複数枚のエアガイド板（３４）を用いていることを特徴としている。この請求項２に記載の発明によれば、より均一に空気流を拡散させることができる。   Further, the invention according to claim 2 is characterized in that a plurality of air guide plates (34) are used as the air flow diffusion means (34). According to the second aspect of the present invention, the air flow can be diffused more uniformly.

また、請求項３に記載の発明では、空気流拡散手段（３４）として、車両上下方向で空気流を拡散させるエアガイド板部分（３４Ｕ、３４Ｄ）と、車両左右方向で空気流を拡散させるエアガイド板部分（３４Ｌ、３４Ｒ）とをあわせ持っていることを特徴としている。この請求項３に記載の発明によれば、より冷却用熱交換器（２０）の全通風面に均一に空気流を拡散させることができる。   In the invention according to claim 3, as the air flow diffusing means (34), the air guide plate portion (34U, 34D) for diffusing the air flow in the vertical direction of the vehicle and the air for diffusing the air flow in the horizontal direction of the vehicle. It is characterized by having a guide plate portion (34L, 34R) together. According to the third aspect of the present invention, the air flow can be more uniformly diffused over the entire ventilation surface of the cooling heat exchanger (20).

また、請求項４に記載の発明では、空調空気の通路を成す車両用空調ユニット（１）と、車両用空調ユニット（１）内に空調用空気を送風する送風手段（２）と、車両用空調ユニット（１）内に配置されて空調用空気を冷却する冷却用熱交換器（２０）とを備えた車両用空調装置において、
送風手段（２）と冷却用熱交換器（２０）との間に、送風手段（２）からの空気流の一部の流れを偏向させる空気流偏向凸部（３５）を設けて空調用空気が冷却用熱交換器（２０）の全通風面を略均等に通過するようにしたことを特徴としている。 According to a fourth aspect of the present invention, there is provided a vehicle air conditioning unit (1) that forms a passage for conditioned air, a blower means (2) that blows air for air conditioning into the vehicle air conditioning unit (1), and a vehicle In a vehicle air conditioner provided with a cooling heat exchanger (20) arranged in the air conditioning unit (1) for cooling air conditioning air,

Is characterized in that it passes through the entire ventilation surface of the cooling heat exchanger (20) substantially evenly.

これは、空気流偏向凸部（３５）を設けて空気流の一部の流れを偏向させることで通風量の多い部分から少ない部分へ空気流を拡散させ、冷却用熱交換器（２０）の通過風速を均一にするものである。この請求項４に記載の発明によれば、送風手段（２）と冷却用熱交換器（２０）との間に距離が取れない場合においても、間に空気流偏向凸部（３５）を設けることにより、送風手段（２）から送風された風の一部が空気流偏向凸部（３５）によって偏向されて全体が均一化され、冷却用熱交換器（２０）を通過する空気流の偏りが軽減（風速の高い部分が低減）されるようになる。   This is because an air flow deflecting projection (35) is provided to deflect a part of the air flow, thereby diffusing the air flow from a portion with a large amount of air flow to a portion with a small amount of air flow, and the cooling heat exchanger (20). This makes the passing wind speed uniform. According to the fourth aspect of the present invention, even when the distance between the air blowing means (2) and the cooling heat exchanger (20) cannot be secured, the air flow deflection convex portion (35) is provided between them. As a result, a part of the air blown from the blowing means (2) is deflected by the air flow deflecting convex portion (35), and the whole is made uniform, and the air flow passing through the cooling heat exchanger (20) is uneven. Is reduced (the part with high wind speed is reduced).

このため、冷却用熱交換器（２０）での冷却により結露した水は、冷却用熱交換器（２０）のコア表面を伝って自重で流れ落ちて冷却用熱交換器（２０）下方に設けられたドレインポート（２３）から車外に正常に排水され、冷却用熱交換器（２０）からの水飛びを防止することができる。尚、この空気流偏向凸部（３５）は、車両用空調ユニット（１）の外殻を形成する空調ケース（２１）に一体に形成しても良いし、別体を組み付ける構成であっても良い。   For this reason, the water condensed by cooling in the cooling heat exchanger (20) flows down along the core surface of the cooling heat exchanger (20) by its own weight and is provided below the cooling heat exchanger (20). Then, the water is normally drained from the drain port (23) to the outside of the vehicle, and water splash from the cooling heat exchanger (20) can be prevented. In addition, this air flow deflection | deviation convex part (35) may be integrally formed in the air-conditioning case (21) which forms the outer shell of a vehicle air-conditioning unit (1), or it may be the structure which assembles another body. good.

また、請求項５に記載の発明では、空気流偏向凸部（３５）を複数形成していることを特徴としている。この請求項５に記載の発明によれば、より空気流を均一化させることができる。   Further, the invention according to claim 5 is characterized in that a plurality of air flow deflection convex portions (35) are formed. According to the fifth aspect of the present invention, the air flow can be made more uniform.

また、請求項６に記載の発明では、送風手段（２）と冷却用熱交換器（２０）との間に、車両上下方向で空気流を偏向させる空気流偏向凸部（３５）と、車両左右方向で空気流を偏向させる空気流偏向凸部（３５）とをあわせて形成していることを特徴としている。この請求項６に記載の発明によれば、より冷却用熱交換器（２０）の全通風面に空気流を均一化させることができる。ちなみに、上記各手段の括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示す一例である。   Further, in the invention described in claim 6, between the air blowing means (2) and the heat exchanger for cooling (20), the air flow deflecting convex portion (35) for deflecting the air flow in the vehicle vertical direction, the vehicle It is characterized in that it is formed with an air flow deflection convex portion (35) for deflecting the air flow in the left-right direction. According to the sixth aspect of the present invention, the air flow can be made more uniform over the entire ventilation surface of the cooling heat exchanger (20). Incidentally, the reference numerals in parentheses of the above means are examples showing the correspondence with the specific means described in the embodiments described later.

（第１実施形態）
以下、本発明の実施の形態について添付図面を参照しながら詳細に説明する。図１（ａ）は本発明の第１実施形態における車両用空調ユニット１の概略構造を説明する模式図であり、（ｂ）はエバポレータ２０下流の風速分布を示す部分模式図である。 (First embodiment)
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1A is a schematic diagram illustrating a schematic structure of the vehicle air conditioning unit 1 according to the first embodiment of the present invention, and FIG. 1B is a partial schematic diagram illustrating a wind speed distribution downstream of the evaporator 20.

車両用空調装置の図示しない冷凍サイクルは、冷媒を吸入・圧縮・吐出するコンプレッサを有し、このコンプレッサには動力断続用の電磁クラッチが備えられている。コンプレッサには電磁クラッチおよびベルトを介して車両走行用エンジンの動力が伝達されて駆動され、電磁クラッチへの通電を空調用の制御手段を成す空調用制御装置にて断続することによりコンプレッサの運転が断続される。   A refrigeration cycle (not shown) of a vehicle air conditioner has a compressor that sucks, compresses, and discharges refrigerant, and this compressor is provided with an electromagnetic clutch for intermittent power. The compressor is driven by the power of the vehicle running engine transmitted through an electromagnetic clutch and a belt, and the operation of the compressor is operated by intermittently energizing the electromagnetic clutch by an air conditioning control device that constitutes air conditioning control means. Intermittently.

コンプレッサから吐出された高温高圧の過熱気相冷媒は、冷媒凝縮器を成すコンデンサに流入し、冷却ファンより送風される外気と熱交換して冷却され凝縮する。このコンデンサからの凝縮冷媒は、気液を分離して液冷媒を溜めると共に、液冷媒を導出する受液器を成すレシーバを経て、減圧手段を成す膨張弁により低圧に減圧され、低圧の気液２相状態となる。膨張弁は冷媒蒸発器を成すエバポレータ（冷却用熱交換器）２０出口の冷媒過熱度を調節するように弁の開度（冷媒流量）を調節する温度式膨張弁などである。   The high-temperature and high-pressure superheated gas-phase refrigerant discharged from the compressor flows into a condenser forming a refrigerant condenser, and is cooled and condensed by exchanging heat with the outside air blown from the cooling fan. The condensed refrigerant from the condenser separates gas and liquid and accumulates the liquid refrigerant, and is decompressed to a low pressure by an expansion valve that constitutes a decompression means via a receiver that constitutes a receiver for leading out the liquid refrigerant. It becomes a two-phase state. The expansion valve is a temperature type expansion valve that adjusts the degree of opening (refrigerant flow rate) of the valve so as to adjust the degree of refrigerant superheat at the outlet of the evaporator (cooling heat exchanger) 20 constituting the refrigerant evaporator.

冷却用熱交換器であるエバポレータ２０は、膨張弁により減圧された低圧冷媒を蒸発させて車室内へ送風される空気を冷却するものである。車両用空調ユニット１は通常、車室内前部の計器盤内側に搭載されている。車両用空調ユニット１の空調ケース２１は、車室内へ向かって送風される空気の通路を構成するものであり、この空調ケース２１内にエバポレータ２０が設置されている。   The evaporator 20 that is a heat exchanger for cooling evaporates the low-pressure refrigerant decompressed by the expansion valve and cools the air blown into the vehicle interior. The vehicle air conditioning unit 1 is normally mounted inside the instrument panel at the front of the vehicle interior. The air conditioning case 21 of the vehicle air conditioning unit 1 constitutes a passage for air blown toward the vehicle interior, and an evaporator 20 is installed in the air conditioning case 21.

空調ケース２１において、エバポレータ２０の上流側には送風機（送風手段）２が配置され、送風機２には遠心式送風ファン２２と図示しない駆動用モータとが備えられている。送風ファン２２の吸入側には図示しない内外気切替箱が配置され、この内外気切替箱内の内外気切替ドアにより外気（車室外空気）または内気（車室内空気）が切替導入される。また、空調ケース２１内で、エバポレータ２０の下流側にはエアミックスドア２４が配置され、このエアミックスドア２４の下流側には車両走行用エンジンの冷却水（温水）を熱源として空気を加熱するヒータコア２５が加熱用熱交換器として設置されている。   In the air conditioning case 21, a blower (blower unit) 2 is disposed on the upstream side of the evaporator 20, and the blower 2 is provided with a centrifugal blower fan 22 and a drive motor (not shown). An inside / outside air switching box (not shown) is disposed on the suction side of the blower fan 22, and outside air (vehicle interior air) or room air (vehicle interior air) is switched and introduced by an inside / outside air switching door in the inside / outside air switching box. In the air conditioning case 21, an air mix door 24 is disposed on the downstream side of the evaporator 20, and the air is heated on the downstream side of the air mix door 24 using cooling water (hot water) of the vehicle running engine as a heat source. The heater core 25 is installed as a heat exchanger for heating.

そして、このヒータコア２５の側方（上方部）には、ヒータコア２５をバイパスして空気（冷風）を流すバイパス通路２６が形成されている。エアミックスドア２４は回動可能な板状ドアであり、ヒータコア２５を通過し加熱されて温風となる風量と、バイパス通路２６を通過する冷風の風量との風量割合を調節するものであって、この冷温風の風量割合の調節により車室内への吹出空気温度を調節する。従って、エアミックスドア２４は車室内への吹出空気の温度調節手段を構成している。よって、ヒータコア２５からの温風と、バイパス通路２６からの冷風とを空気混合部２７で混合して、所望温度の空気を作り出すことができる。   A bypass passage 26 that bypasses the heater core 25 and flows air (cold air) is formed on the side (upper portion) of the heater core 25. The air mix door 24 is a pivotable plate-like door, and adjusts the air volume ratio between the air volume that passes through the heater core 25 and is heated and becomes warm air, and the air volume of the cool air that passes through the bypass passage 26. The temperature of the air blown into the passenger compartment is adjusted by adjusting the air volume ratio of the cold / hot air. Accordingly, the air mix door 24 constitutes temperature adjusting means for the air blown into the vehicle interior. Therefore, the air at the desired temperature can be created by mixing the warm air from the heater core 25 and the cool air from the bypass passage 26 in the air mixing unit 27.

更に、空調ケース２１内で空気混合部２７の下流側には吹出モード切替部が構成されている。すなわち、車両前面窓ガラスの内面に空気を吹き出す開口部を成すデフロスタ開口部２８、車室内乗員の上半身側に向けて空気を吹き出す開口部を成すフェイス開口部２９、および車室内乗員の足元に向けて空気を吹き出す開口部を成すフット開口部３０などの開口部を吹出モードドア３１〜３３により開閉するようになっている。   Further, an air outlet mode switching unit is configured on the downstream side of the air mixing unit 27 in the air conditioning case 21. That is, a defroster opening 28 that forms an opening that blows air to the inner surface of the front window glass of the vehicle, a face opening 29 that forms an opening that blows air toward the upper body side of the passenger in the vehicle interior, and the feet of the passengers in the vehicle interior Thus, openings such as a foot opening 30 that forms an opening through which air is blown are opened and closed by blowing mode doors 31-33.

尚、エバポレータ２０下側の空調ケース２１には、空気が冷やされてエバポレータ２０の表面で凝縮した凝縮水を車外に排出するためのドレインポート２３が形成されている。上記した車両用空調ユニット１の開口部２８〜３０と車室内に設けられた各吹出口とは、図示しない送風ダクトにて接続して連通させられている。より具体的に、デフロスタ開口部２８はデフロスタ送風ダクトを介して吹出口を成すデフロスタ吹出口に接続され、このデフロスタ吹出口から、車両前面窓ガラスの内面に向けて風を吹き出す。   The air conditioning case 21 below the evaporator 20 is formed with a drain port 23 for discharging condensed water condensed on the surface of the evaporator 20 by cooling the air. The above-described openings 28 to 30 of the vehicle air conditioning unit 1 and the respective air outlets provided in the passenger compartment are connected and communicated with each other through an air duct (not shown). More specifically, the defroster opening 28 is connected to a defroster outlet that forms an outlet through a defroster air duct, and blows wind from the defroster outlet toward the inner surface of the front window glass of the vehicle.

また、フェイス開口部２９は更にセンタフェイス開口部とサイドフェイス開口部とに分かれており、そのそれぞれが右側用（例えば運転席側用）と左側用（例えば助手席側用）とに分けられている。センタフェイス開口部はセンタフェイス送風ダクトを介して計器盤左右方向の中央部上方側に配置されている吹出口を成すセンタフェイス吹出口４に接続され、このセンタフェイス吹出口から車室内中央部の乗員頭部に向けて風を吹き出す。   The face opening 29 is further divided into a center face opening and a side face opening, each of which is divided into a right side (for example, for the driver's seat side) and a left side (for example, for the passenger's side). Yes. The center face opening is connected to a center face air outlet 4 that forms an air outlet located above the central portion in the lateral direction of the instrument panel via a center face air duct. Blows the wind toward the head of the passenger.

また、サイドフェイス開口部はサイドフェイス送風ダクトを介し、計器盤左右両端部の上方側に配置されている吹出口を成すサイドフェイス吹出口に接続される。そして、サイドフェイス吹出口には周知な如く手動操作される風向変更装置を備えており、この風向き変更装置の風向板の方向調整により、吹出空気を車室内左右両側部の乗員頭部側または車両側面窓ガラスに向けて風を吹き出すことが可能になっている。   Moreover, a side face opening part is connected to the side face blower outlet which comprises the blower outlet arrange | positioned through the side face ventilation duct at the upper side of the instrument panel right and left both ends. The side face outlet is equipped with a wind direction changing device that is manually operated as is well known, and by adjusting the direction of the wind direction plate of the wind direction changing device, the blown air is sent to the occupant head side or the vehicle on both the left and right sides of the vehicle interior. It is possible to blow wind toward the side window glass.

また、フット開口部３０も右側用（運転席側用）と左側用（助手席側用）とに分けられており、それぞれがフット送風ダクトを介して吹出口を成すフット吹出口に接続され、このフット吹出口から左右の乗員足元に温風を吹き出す。そして、このような構成の車両用空調ユニット１は、図示しない各種センサから先の空調用制御装置に信号が入力されると共に、空調用制御装置から車両用空調ユニット１、送風機２、電磁クラッチなどに制御信号が出されて運転が制御される。   Further, the foot opening 30 is also divided into a right side (for the driver's seat side) and a left side (for the passenger side), each connected to a foot outlet that forms an outlet through a foot air duct, Hot air is blown out from the foot outlet to the left and right passenger feet. In the vehicle air conditioning unit 1 having such a configuration, signals are input from various sensors (not shown) to the previous air conditioning control device, and the vehicle air conditioning unit 1, the blower 2, the electromagnetic clutch, and the like are transmitted from the air conditioning control device. A control signal is issued to control the operation.

次に、本発明の要部であり本実施形態での特徴であるエアガイド板（空気流拡散手段）３４と、その効果について説明する。上述したように、空調空気の通路を成す車両用空調ユニット１と、車両用空調ユニット１内に空調用空気を送風する送風機２と、車両用空調ユニット１内に配置されて空調用空気を冷却するエバポレータ２０とを備えた車両用空調装置において、送風機２とエバポレータ２０との間の通路拡大部Ｋに、送風機２からの空気流を拡散させる空気流拡散手段としてエアガイド板３４を設け、空調用空気がエバポレータ２０の全通風面を略均等に通過するようにしている。   Next, an air guide plate (air flow diffusing means) 34, which is a main part of the present invention and is a feature of the present embodiment, and effects thereof will be described. As described above, the vehicle air-conditioning unit 1 that forms a passage for the air-conditioned air, the blower 2 that blows the air-conditioning air into the vehicle air-conditioning unit 1, and the air-conditioning air that is disposed in the vehicle air-conditioning unit 1 to cool the air-conditioning air. In the vehicle air conditioner provided with the evaporator 20 that performs the above operation, an air guide plate 34 is provided in the passage expanding portion K between the blower 2 and the evaporator 20 as an air flow diffusion means for diffusing the air flow from the blower 2. The working air passes through the entire ventilation surface of the evaporator 20 substantially evenly.

エバポレータ２０からの水飛びは、送風機２とエバポレータ２０間の通路拡大部Ｋでの風速分布の不均一が原因で発生する点に着目し、送風機２後の通路拡大部Ｋにエアガイド板３４を設けて通風量の多い部分から少ない部分へ空気流を拡散させ、エバポレータ２０の通過風速を均一にするものである。   Paying attention to the fact that the water splash from the evaporator 20 is caused by the non-uniformity of the wind speed distribution in the passage enlargement portion K between the blower 2 and the evaporator 20, the air guide plate 34 is attached to the passage enlargement portion K after the blower 2. It is provided to diffuse the air flow from a portion with a large amount of air flow to a portion with a small amount of air flow, so that the passing air speed of the evaporator 20 is made uniform.

これによれば、送風機２とエバポレータ２０との間に距離が取れない場合においても、通路拡大部Ｋにエアガイド板３４を設けることにより、送風機２から送風された風が空気流拡散手段（３４）によって拡散されて均一化され、エバポレータ２０を通過する空気流の偏りが軽減（風速の高い部分が低減）されるようになる。   According to this, even when the distance between the blower 2 and the evaporator 20 cannot be secured, by providing the air guide plate 34 in the passage enlargement portion K, the air blown from the blower 2 is supplied to the air flow diffusing means (34 ), The air flow passing through the evaporator 20 is less biased (the portion with high wind speed is reduced).

このため、エバポレータ２０での冷却により結露した水は、エバポレータ２０のコア表面を伝って自重で流れ落ちてエバポレータ２０下方に設けられたドレインポート２３から車外に正常に排水され、エバポレータ２０からの水飛びを防止することができる。尚、このエアガイド板３４は、車両用空調ユニット１の外殻を形成する空調ケース２１に一体に形成しても良いし、別体を組み付ける構成であっても良い。   For this reason, water condensed by cooling in the evaporator 20 flows down along the core surface of the evaporator 20 due to its own weight and is normally drained out of the vehicle from the drain port 23 provided below the evaporator 20, and water splashes from the evaporator 20. Can be prevented. The air guide plate 34 may be formed integrally with the air conditioning case 21 that forms the outer shell of the vehicle air conditioning unit 1 or may be configured to be assembled separately.

（第２実施形態）
図２は、本発明の第２実施形態における車両用空調ユニット１の概略構造を説明する模式図である。上述した第１実施形態と異なる点は、空気流拡散手段３４として、複数枚のエアガイド板３４を用いている。これによれば、より均一に空気流を拡散させることができる。 (Second Embodiment)
FIG. 2 is a schematic diagram illustrating a schematic structure of the vehicle air conditioning unit 1 according to the second embodiment of the present invention. The difference from the first embodiment described above is that a plurality of air guide plates 34 are used as the air flow diffusion means 34. According to this, the air flow can be diffused more uniformly.

（第３実施形態）
図３は、本発明の第３実施形態における車両用空調ユニット１の概略構造を説明する模式図であり、図４は、図３におけるエアガイド板３４Ａの形状を説明する斜視図である。 (Third embodiment)
FIG. 3 is a schematic view for explaining the schematic structure of the vehicle air conditioning unit 1 according to the third embodiment of the present invention, and FIG. 4 is a perspective view for explaining the shape of the air guide plate 34A in FIG.

上述した実施形態と異なる点は、空気流拡散手段３４として、車両上下方向で空気流を拡散させる上方エアガイド板３４Ｕと下方エアガイド板３４Ｄ、車両左右方向で空気流を拡散させる左方エアガイド板３４Ｌと右方エアガイド板３４Ｒとをあわせ持っている。これによれば、よりエバポレータ２０の全通風面に均一に空気流を拡散させることができる。但し、必ずしも上記した各エアガイド板３４Ｕ・３４Ｄ・３４Ｌ・３４Ｒを備えている必要は無く、必要に応じた組み合わせで構成すれば良い。   The difference from the embodiment described above is that the air flow diffusing means 34 is an upper air guide plate 34U and a lower air guide plate 34D that diffuse the air flow in the vehicle vertical direction, and a left air guide that diffuses the air flow in the vehicle left-right direction. The plate 34L and the right air guide plate 34R are held together. According to this, the air flow can be more uniformly diffused over the entire ventilation surface of the evaporator 20. However, the air guide plates 34U, 34D, 34L, and 34R described above are not necessarily provided, and may be configured in combination as necessary.

（第４実施形態）
図５は、本発明の第４実施形態における車両用空調ユニット１の概略構造を説明する模式図である。上述した実施形態と異なる点は、送風機２とエバポレータ２０との間に、送風機２からの空気流の一部の流れを偏向させる空気流偏向凸部３５を設けて空調用空気がエバポレータ２０の全通風面を略均等に通過するようにしている。 (Fourth embodiment)
FIG. 5 is a schematic diagram illustrating a schematic structure of the vehicle air conditioning unit 1 according to the fourth embodiment of the present invention. The difference from the above-described embodiment is that an air flow deflecting convex portion 35 for deflecting a part of the air flow from the blower 2 is provided between the blower 2 and the evaporator 20 so that the air-conditioning air can be completely removed from the evaporator 20. It passes through the ventilation surface almost evenly.

これは、空気流偏向凸部３５を設けて空気流の一部の流れを偏向させることで通風量の多い部分から少ない部分へ空気流を拡散させ、エバポレータ２０の通過風速を均一にするものである。これによれば、送風機２とエバポレータ２０との間に距離が取れない場合においても、間に空気流偏向凸部３５を設けることにより、送風機２から送風された風の一部が空気流偏向凸部３５によって偏向されて全体が均一化され、エバポレータ２０を通過する空気流の偏りが軽減（風速の高い部分が低減）されるようになる。   This is to provide an air flow deflecting convex portion 35 to deflect a part of the air flow, thereby diffusing the air flow from a portion with a large amount of air flow to a portion with a small amount of air flow to make the passing air speed of the evaporator 20 uniform. is there. According to this, even when the distance between the blower 2 and the evaporator 20 cannot be secured, by providing the air flow deflection convex portion 35 therebetween, a part of the wind blown from the blower 2 can be made to the air flow deflection convex portion. By being deflected by the portion 35, the whole is made uniform, and the deviation of the air flow passing through the evaporator 20 is reduced (the portion where the wind speed is high is reduced).

このため、エバポレータ２０での冷却により結露した水は、エバポレータ２０のコア表面を伝って自重で流れ落ちてエバポレータ２０下方に設けられたドレインポート２３から車外に正常に排水され、エバポレータ２０からの水飛びを防止することができる。尚、この空気流偏向凸部３５は、車両用空調ユニット１の外殻を形成する空調ケース２１に一体に形成しても良いし、別体を組み付ける構成であっても良い。   For this reason, water condensed by cooling in the evaporator 20 flows down along the core surface of the evaporator 20 due to its own weight and is normally drained out of the vehicle from the drain port 23 provided below the evaporator 20, and water splashes from the evaporator 20. Can be prevented. In addition, this airflow deflection | deviation convex part 35 may be integrally formed in the air-conditioning case 21 which forms the outer shell of the vehicle air conditioning unit 1, and the structure which assembles | attaches another body may be sufficient as it.

また、図示は省略するが、空気流偏向凸部３５は複数形成しても良く、これによれば、より空気流を均一化させることができる。また、これも図示は省略するが、送風機２とエバポレータ２０との間に、車両上下方向で空気流を偏向させる空気流偏向凸部３５と、車両左右方向で空気流を偏向させる空気流偏向凸部３５とをあわせて形成しても良く、これによれば、よりエバポレータ２０の全通風面に空気流を均一化させることができる。   Although not shown, a plurality of air flow deflection convex portions 35 may be formed, and according to this, the air flow can be made more uniform. Also, although not shown in the figure, an air flow deflection convex portion 35 that deflects the air flow in the vehicle vertical direction and an air flow deflection convex portion that deflects the air flow in the vehicle left and right direction between the blower 2 and the evaporator 20.
