Description

本発明は、排水部に特徴を有する車両用空調装置に関する。   The present invention relates to a vehicle air conditioner characterized by a drainage section.

従来より、自動車などで使用される車両用空調装置には、車両用空調装置のハウジング内に冷却用熱交換器が設けられており、この冷却用熱交換器に空気を通過させることにより、冷却された空気が得られるようになっている。上記車両用空調装置において、冷却用熱交換器により空気が冷却されると、空気中に含まれる水分が凝縮して凝縮水が発生する。この凝縮水は、車両用空調装置のハウジング内底部に溜まるので、例えば、特許文献1では、ハウジング内底部に排水口が設けられ、この排水口から車体パネルへ向かって突出するように形成された排水管から凝縮水が排水されるようになっている。具体的には、ハウジング底部において、ハウジングと一体的に形成された排水管が前方向下側へ突出しており、この排水管を直接的に車両前部の車体パネルに貫通させることで、ハウジング底部に溜まった凝縮水を車室外へ排水できるようになっている。
特開2004−98740号公報
Conventionally, in a vehicle air conditioner used in an automobile or the like, a cooling heat exchanger is provided in a housing of the vehicle air conditioner, and cooling is performed by passing air through the cooling heat exchanger. The air that has been made can be obtained. In the vehicle air conditioner, when the air is cooled by the cooling heat exchanger, moisture contained in the air is condensed to generate condensed water. Since this condensed water accumulates in the inner bottom part of the housing of the vehicle air conditioner, for example, in Patent Document 1, a drain outlet is provided in the inner bottom part of the housing, and is formed so as to protrude from the drain outlet toward the vehicle body panel. Condensed water is drained from the drain pipe. Specifically, a drain pipe integrally formed with the housing protrudes downward in the front direction at the bottom of the housing, and the drain pipe is directly passed through the vehicle body panel at the front of the vehicle, thereby The condensate collected in the vehicle can be drained outside the passenger compartment.
JP 2004-98740 A

ところで、車両用空調装置内の凝縮水を車室外へ排水するために、車体パネルに設けられる貫通穴は、レイアウト上の問題等から、車両用空調装置の下方に位置する車体パネルの一部に設けるのが困難なことがあり、例えば、フロアーパネルのトンネル部分の縦壁のように、貫通穴の中心軸が略水平を向くような部位において形成し、この貫通穴より車室外へ凝縮水を排水しなければならない場合がある。このような場合、車両用空調装置のハウジング底部の排水口に排水管の一方を繋ぎ、排水管の他方には、ドレンプラグを設け、このドレンプラグを貫通穴に嵌合することにより、凝縮水を車室外へ排水できるようにすることが考えられる。   By the way, in order to drain the condensed water in the vehicle air conditioner to the outside of the passenger compartment, a through hole provided in the vehicle body panel is formed on a part of the vehicle body panel located below the vehicle air conditioner due to layout problems. For example, it is formed in a part where the central axis of the through hole faces substantially horizontal, such as the vertical wall of the tunnel part of the floor panel, and condensed water is discharged from the through hole to the outside of the passenger compartment. It may be necessary to drain. In such a case, one end of the drain pipe is connected to the drain outlet at the bottom of the housing of the vehicle air conditioner, and a drain plug is provided on the other end of the drain pipe. It is conceivable that the water can be drained out of the passenger compartment.

しかし、ドレンプラグを貫通穴に嵌合する構造の場合、ドレンプラグの製造誤差等が原因となって、ドレンプラグがフロアーパネル等に適切に組み付けられず、不十分な嵌合状態となることが予想され、そうなった場合には、ドレンプラグから排水される凝縮水が車室内に流れ込んでしまい、異臭や錆の発生要因となってしまう。   However, in the case of a structure in which the drain plug is fitted into the through hole, the drain plug may not be properly assembled to the floor panel or the like due to a manufacturing error of the drain plug, resulting in an insufficient fitting state. If it is anticipated, if this happens, the condensed water drained from the drain plug will flow into the passenger compartment, which will cause odor and rust.

本発明は斯かる点に鑑みてなされたものであり、その目的とするところは、車両用空調装置内のハウジング底部から延びる排水管に設けられたドレンプラグを車体パネルに嵌合する際に、ドレンプラグの嵌合が不十分であっても車室内に凝縮水が流れ込みにくい排水構造とすることにある。   The present invention has been made in view of such points, and the purpose of the present invention is to fit a drain plug provided on a drain pipe extending from the bottom of a housing in a vehicle air conditioner to a vehicle body panel. A drainage structure in which condensed water is difficult to flow into the passenger compartment even if the drain plug is not sufficiently fitted.

上記目的を達成するために、第1の発明では、通過する空気を冷却する冷却用熱交換器を収容するハウジング部を有し、上記ハウジング部には、底部に排水口が形成され、上記冷却用熱交換器で凝縮され、上記ハウジング部の底部に溜まる凝縮水を、上記排水口より排水するように構成された車両用空調装置において、上記ハウジング部の下方には、凝縮水を車室外まで導く排水管が設けられ、該排水管の上流端は、上記ハウジング部の底部の上記排水口に接続され、上記排水管の下流端には、車体に設けられた横方向に貫通する貫通穴に車室内側から車室外側に挿入して嵌合する接続口部が形成され、該接続口部の開口周縁には、上記接続口部の上記貫通穴への挿入方向と交差する方向に延出し、上記接続口部を上記貫通穴に嵌合する際、上記接続口部を上記貫通穴への挿入方向に対して傾けることにより上記貫通穴に通過させ、且つ、上記接続口部を上記貫通穴に嵌合した状態で、下方に延出して上記貫通穴の車室外側開口周縁下部に対応する難変形性の板状部が一体に設けられ、該板状部は、その水平方向両側に位置する端部に当該端部に沿って延びる突条部を有し、上記接続口部が上記貫通穴に対して不十分な嵌合状態である際、上記貫通穴の車室外側開口周縁下部に接触して上記接続口部が上記貫通穴から抜け出るのを規制する構成とした。 In order to achieve the above object, according to the first aspect of the present invention, there is provided a housing portion that houses a heat exchanger for cooling that cools the air passing therethrough. In the vehicle air conditioner configured to drain the condensed water condensed in the heat exchanger and accumulated in the bottom of the housing part from the drain port, the condensed water is disposed below the housing part to the outside of the passenger compartment. A drain pipe is provided, the upstream end of the drain pipe is connected to the drain port at the bottom of the housing part, and the downstream end of the drain pipe is a through-hole penetrating in the lateral direction provided in the vehicle body. A connection port portion that is inserted and fitted to the vehicle interior side from the vehicle interior side is formed, and the connection port portion extends in a direction intersecting with the insertion direction of the connection port portion into the through hole. When fitting the connection port portion into the through hole, The connecting port portion is passed through the through hole by inclining with respect to the insertion direction into the through hole, and the connecting port portion is extended downward with the connecting port portion fitted into the through hole. A hard-to-deform plate-like portion corresponding to a lower portion of the outer periphery of the vehicle compartment outer opening is integrally provided, and the plate-like portion has protrusions extending along the end portions at the ends located on both sides in the horizontal direction. And when the connection port portion is in an insufficiently fitted state with respect to the through hole, the connection port portion comes out of contact with the lower portion of the through hole on the outer periphery of the vehicle interior outside opening. The configuration is regulated.

この構成によれば、排水管の下流側にある板状部は、接続口部において、鉛直方向下側に位置する開口の周縁に設けられているので、接続口部を車体の貫通穴に嵌合させた時に、貫通穴の下部に位置することとなる。そして、板状部は車室外へと突出しているので、接続口部と貫通穴の嵌合が不十分であっても、凝縮水が板状部を伝って、車室外へと排水される。   According to this configuration, the plate-like portion on the downstream side of the drainage pipe is provided at the peripheral edge of the opening located on the lower side in the vertical direction at the connection port portion, so that the connection port portion is fitted into the through hole of the vehicle body. When they are combined, they are located below the through holes. And since the plate-shaped part protrudes out of a vehicle interior, even if a fitting of a connection port part and a through-hole is inadequate, condensed water flows along a plate-shaped part and is drained out of a vehicle interior.

また、この構成によれば、板状部における水平方向両端に位置する端部が、該端部に沿って延びる突条部を有しているので、他の物体が板状部に接触しても、突条部によって、物体と接続口部の開口との間に空間が形成され、他の物体により接続口部の開口が塞がれるのを防ぐ。 Further , according to this configuration, since the end portions located at both ends in the horizontal direction of the plate-like portion have the protrusions extending along the end portions, other objects come into contact with the plate-like portion. In addition, the ridge portion forms a space between the object and the opening of the connection port portion, and prevents the opening of the connection port portion from being blocked by another object.

の発明では、第の発明に記載の車両用空調装置であって、上記突条部が、上記板状部の補強部である構成とした。 In the second invention, the vehicular air conditioner according to the first invention is configured such that the protruding portion is a reinforcing portion of the plate-like portion.

この構成によれば、突条部が、板状部を補強するので、他の物体が板状部に接触しても、突条部により板状部が変形するのを防ぐ。   According to this configuration, since the protruding portion reinforces the plate-like portion, even if another object contacts the plate-like portion, the protruding portion prevents the plate-like portion from being deformed.

の発明では、第1又は第2の発明に記載の車両用空調装置であって、上記板状部は、上記接続口部を上記貫通穴に嵌合した状態で、上記貫通穴周りの壁に沿うように形成され、板状部の水平方向両側は、車室外側へ湾曲する構成とした。 According to a third invention, in the vehicle air conditioner according to the first or second invention, the plate-like portion is arranged around the through hole in a state where the connection port portion is fitted into the through hole. It was formed along the wall, and both horizontal sides of the plate-shaped part were configured to curve outward from the passenger compartment.

この構成によれば、接続口部を貫通穴に嵌合する際に、板状部を車室内側から挿入すると、板状部が車体の貫通穴周辺の壁に沿うように位置する。この板状部を挿入する際、板状部の水平方向両端部が湾曲しているので、端部が貫通穴の周縁に当たりにくく、板状部が貫通穴の開口に接触しにくくなる。   According to this configuration, when the plate-like portion is inserted from the vehicle interior side when the connection port portion is fitted into the through-hole, the plate-like portion is positioned along the wall around the through-hole of the vehicle body. When the plate-like portion is inserted, since both ends in the horizontal direction of the plate-like portion are curved, the end portion is unlikely to hit the periphery of the through hole, and the plate-like portion is difficult to contact the opening of the through hole.

の発明では、第1乃至第いずれか1つの発明に記載の車両用空調装置であって、上記板状部は、車体の壁に沿うように形成され、上記接続口部の開口周縁には、車体に設けられた貫通穴に係合する、少なくとも1以上の係合突起部が形成されている構成とした。 According to a fourth invention, in the vehicle air conditioner according to any one of the first to third inventions, the plate-like portion is formed along the wall of the vehicle body, and the opening periphery of the connection port portion In this configuration, at least one or more engaging protrusions that are engaged with through holes provided in the vehicle body are formed.

この構成によれば、接続口部を貫通穴に組み付けた際に、板状部が車体の壁に沿うように位置し、且つ、係合突起部が貫通穴に係合することになる。   According to this configuration, when the connection port portion is assembled to the through hole, the plate-like portion is positioned along the wall of the vehicle body, and the engaging protrusion is engaged with the through hole.

第1の発明によれば、接続口部の開口から流れ出る凝縮水が、板状部を伝って流れるようになるので、接続口部が、車体の貫通穴に不十分な嵌合状態であっても、板状部は、車室外に位置することとなり、凝縮水を車室内に流入しないようにできる。   According to the first invention, since the condensed water flowing out from the opening of the connection port portion flows along the plate-like portion, the connection port portion is in an insufficiently fitted state in the through hole of the vehicle body. However, the plate-like portion is located outside the vehicle compartment, and the condensed water can be prevented from flowing into the vehicle compartment.

また、板状部における水平方向の両端に位置する端部突条部が形成されており、他の物体が板状部と接触しても、突条部によって、物体と接続口部の開口との間に空間が形成され、凝縮水を接続口部の開口から車室外へ排水できなくなることを回避できる。 Further, a protrusion portion is formed on an end portion positioned in a horizontal direction at both ends of the plate-like portion, even if another object is in contact with the plate portion, the ridge portion, the object and the joint port openings A space is formed between the two and the condensate, and it can be avoided that the condensed water cannot be drained from the opening of the connection port portion to the outside of the passenger compartment.

の発明によれば、突条部が板状部を補強しているので、板状部が、他の物体との接触等により変形し、接続口部の開口を塞ぎ、凝縮水を車室外へ排水できなくなるといったことを回避できる。 According to the second invention, since the ridge portion reinforces the plate-like portion, the plate-like portion is deformed by contact with other objects, etc., closes the opening of the connection port portion, and condensate water is discharged. It is possible to avoid being unable to drain outside the room.

の発明によれば、板状部の水平方向両側に位置する端部が、車室外側へ湾曲しているので、接続口部を貫通穴に嵌合する際、板状部を貫通穴に挿入し易く、簡易に接続口部を車体に嵌合することができる。 According to the third invention, since the end portions located on both sides in the horizontal direction of the plate-like portion are curved outward from the passenger compartment, the plate-like portion is inserted into the through-hole when the connection port portion is fitted into the through-hole. The connection port portion can be easily fitted to the vehicle body.

の発明によれば、接続口部の開口周縁には、車体の壁に沿うように形成された板状部と、少なくとも1以上の係合突起部を有するので、板状部と係合突起部とで、接続口部を貫通穴から抜けないようにすることができる。 According to the fourth aspect of the invention, since the opening periphery of the connection port portion has the plate-like portion formed along the wall of the vehicle body and at least one engagement protrusion, the plate-like portion is engaged. It is possible to prevent the connection port portion from coming out of the through hole with the protruding portion.

以下、本発明の実施形態を図面に基づいて詳細に説明する。尚、以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものではない。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.

図1は、本発明の車両用空調装置1を示すものである。この車両用空調装置1は、冷却用熱交換器2や、加熱用熱交換器(図示せず)、各種ダンパ等(図示せず)を収容するハウジング部10を有しており、自動車の車体において、上下及び車幅方向に延びるダッシュパネルB1に取り付けられている。上記車両用空調装置1は、冷却用熱交換器2を通過し冷却された空気と、加熱用熱交換器を通過し加熱された空気とを、ハウジング部10内で各種ダンパにより混合し、自動車の車室内に送風することによって、車室内の温度を調整できるようになっている。   FIG. 1 shows a vehicle air conditioner 1 according to the present invention. The vehicle air conditioner 1 has a housing portion 10 that houses a cooling heat exchanger 2, a heating heat exchanger (not shown), various dampers (not shown), and the like. Are attached to a dash panel B1 extending in the vertical direction and the vehicle width direction. The vehicle air conditioner 1 mixes air cooled by passing through the heat exchanger 2 for cooling and air heated by passing through the heat exchanger for heating with various dampers in the housing portion 10, The temperature inside the vehicle compartment can be adjusted by blowing air into the vehicle compartment.

また、車両用空調装置1では、空気を冷却するために、上記冷却用熱交換器2に空気を通過させると、空気中に含まれる水分が凝縮して凝縮水が生じ、冷却用熱交換器2からハウジング部10の底部に凝縮水が落下する。よって、この凝縮水を車室外へ排水するために、ハウジング部10の底部には、排水口11が設けられ、ハウジング部10の下方には、この排水口11に繋がり、車体におけるフロアーパネルB2まで繋がる排水部3が設けられている。フロアーパネルB2は、車幅方向中央部分が上方に膨らむ膨出部b1を有し、この膨出部b1の右側に位置する面に横方向に貫通する貫通穴H1(図4に示す)が形成され、この貫通穴H1に排水部3が繋がり、凝縮水が車室外へと排水されるようになっている。尚、以下の説明では特に説明しない場合、「前」及び「後」はそれぞれ「車両前後方向前」及び「車両前後方向後」を意味しており、「左」及び「右」は、それぞれ車体を基準とした「車幅方向左」及び「車幅方向右」を意味するものとする。   Further, in the vehicle air conditioner 1, when air is passed through the cooling heat exchanger 2 in order to cool the air, moisture contained in the air is condensed to produce condensed water, and the cooling heat exchanger is generated. The condensed water falls from 2 to the bottom of the housing part 10. Therefore, in order to drain this condensed water to the outside of the passenger compartment, a drain outlet 11 is provided at the bottom of the housing portion 10, and is connected to the drain outlet 11 below the housing portion 10 to the floor panel B 2 in the vehicle body. The drainage part 3 connected is provided. The floor panel B2 has a bulging portion b1 whose center portion in the vehicle width direction swells upward, and a through hole H1 (shown in FIG. 4) penetrating in the lateral direction is formed in a surface located on the right side of the bulging portion b1. And the drainage part 3 is connected to this through-hole H1, and condensed water is drained out of the passenger compartment. Unless otherwise specified in the following description, “front” and “rear” mean “front in the vehicle front-rear direction” and “rear in the vehicle front-rear direction”, respectively, and “left” and “right” It means “vehicle width direction left” and “vehicle width direction right”.

冷却用熱交換器2は、詳細は図示しないが、いわゆるエバポレータと呼ばれるものであり、例えば、アルミニウム合金製の多数のチューブと伝熱フィンとが交互に並べられて一体化されたチューブアンドフィンタイプのものであり、ハウジング部10の前方に、チューブが上下方向に延びるように縦置きに配置されている。   Although not shown in detail, the cooling heat exchanger 2 is a so-called evaporator. For example, a tube-and-fin type in which a large number of aluminum alloy tubes and heat transfer fins are alternately arranged and integrated. The tube is arranged vertically so that the tube extends in the up-down direction in front of the housing portion 10.

ハウジング部10の底部は、前後方向中央部が下方に湾曲しており、冷却用熱交換器2により生じた凝縮水が、ハウジング部10の底部における前後方向中央部に溜まり易くなっている。そして、このハウジング部10の底部における最下端部には排水口11が設けられている。   The bottom part of the housing part 10 has a central part in the front-rear direction curved downward, and the condensed water generated by the cooling heat exchanger 2 is easily collected in the central part in the front-rear direction at the bottom part of the housing part 10. And the drain port 11 is provided in the lowest end part in the bottom part of this housing part 10. As shown in FIG.

図1に示すように、排水部3は、接続口部4と、排水管5と、継ぎ手部9とから構成されている。図4に示すように、接続口部4は、車体のフロアーパネルB2(図1に示す)に設けられた貫通穴H1に嵌合するものであり、本体部6と、突縁部7と、板状部8とから構成され、上記貫通穴H1に車室内側から車室外側に挿入して嵌合するようになっている。   As shown in FIG. 1, the drainage part 3 is composed of a connection port part 4, a drainage pipe 5, and a joint part 9. As shown in FIG. 4, the connection port portion 4 is fitted into a through hole H1 provided in the floor panel B2 (shown in FIG. 1) of the vehicle body, and includes a main body portion 6, a projecting edge portion 7, The plate-shaped portion 8 is configured to be inserted and fitted into the through hole H1 from the vehicle interior side to the vehicle interior side.

図2乃至図4に示すように、本体部6は、略円筒形状の2つの部材がL字状に結合した配管である。図2に示すように、この本体部6の内部は、凝縮水を排水できるように、上流側端部から下流側端部に開口する開口部62dまで連通する連通孔63が形成されている。この本体部6の上流側には、排水管5が接続されている。   As shown in FIGS. 2 to 4, the main body 6 is a pipe in which two substantially cylindrical members are joined in an L shape. As shown in FIG. 2, a communication hole 63 that communicates from the upstream end to the opening 62 d that opens to the downstream end is formed inside the main body 6 so that the condensed water can be drained. A drain pipe 5 is connected to the upstream side of the main body 6.

本体部6は、下流側に行くにつれて断面形状が次第に小さくなる形状をしており、下流部の外周には、本体部6における断面の径方向外方において、上側に突出する第1突起部62aと、水平方向に突出する第2突起部62bと、第3突起部62cとが形成されている。   The main body 6 has a shape in which the cross-sectional shape gradually decreases toward the downstream side, and a first protrusion 62a that protrudes upward on the outer periphery of the downstream portion on the outer side in the radial direction of the cross section of the main body 6. And a second protrusion 62b and a third protrusion 62c projecting in the horizontal direction.

Similarly, the second projecting portion 62b and the third projecting portion 62c are members that project radially outward and the surface located on the downstream side is inclined toward the upstream side toward the tip.

本体部6の下流側には、突起部62a〜62cより上流側に、本体部6における断面の径方向外方に略環状に突出する突縁部7が形成されている。この突縁部7の水平方向一側は、略長方形に突出している。そして、突縁部7の下流側に位置する面には、略環状のシール部材71が設けられており、接続口部4を貫通穴H1に嵌合させたときに、第1突起部62aと、シール部材71との間において、フロアーパネルB2を挟み込み、同様に、第2突起部62bとシール部材71との間と、第3突起部62cとシール部材71との間でフロアーパネルB2を挟み込んで接続口部4が貫通穴H1に嵌合するようになっている。   On the downstream side of the main body portion 6, a protruding edge portion 7 is formed on the upstream side of the projecting portions 62 a to 62 c so as to project in a substantially annular shape outward in the radial direction of the cross section of the main body portion 6. One side of the projecting edge portion 7 in the horizontal direction protrudes in a substantially rectangular shape. A substantially annular sealing member 71 is provided on a surface located on the downstream side of the projecting edge portion 7, and when the connection port portion 4 is fitted into the through hole H1, the first projecting portion 62a and The floor panel B2 is sandwiched between the seal member 71, and similarly, the floor panel B2 is sandwiched between the second protrusion 62b and the seal member 71, and between the third protrusion 62c and the seal member 71. Thus, the connection port 4 is adapted to fit into the through hole H1.

本体部6における開口部62dの周縁下部には、上記接続口部4を上記貫通穴H1に嵌合した状態で、当該貫通孔H1の車室外側開口周縁下部に対応するよう下方に延出する難変形性の板状部8が一体に設けられている。すなわち、上記板状部8は、水平方向に延びる板状の部材であり、水平方向中央部が車室内側に緩やかに湾曲し、水平方向両端部が車室外側に緩やかに湾曲していて、上記接続口部4を上記貫通穴H1に嵌合した状態で、上記貫通穴H1周りの壁に沿うようになっている。この板状部8の下端部は、突縁部7の下端部とほぼ等しい位置となっており、板状部8の水平方向の幅は、本体部6における下流部の外周径とほぼ等しい幅となっている。この板状部8の水平方向一側には、本体部6の下流側に突出し、開口部62dの一側下部から板状部8の上端に沿って一側に延び、板状部8の一側端部に沿って下方に延びる一側突条部81が形成されている。この一側突条部81は、本体部6の下流端よりもさらに下流側に突出している。また、板状部8の他側には、本体部6の下流側に突出し、開口部62dの他側下部から板状部8の上端に沿って他側に延び、板状部8の他側端部に沿って下方に延びる他側突条部82が形成されている。この他側突条部82は、一側突条部81と同様に、本体部6の下流側よりもさらに下流側に突出している。そして、板状部8は、一側突条部81と他側突条部82とによって補強されている。   The lower part of the peripheral edge of the opening 62d in the main body 6 extends downward so as to correspond to the lower peripheral edge of the vehicle interior outside opening of the through hole H1 in a state where the connection port 4 is fitted in the through hole H1. The hardly deformable plate-like portion 8 is integrally provided. That is, the plate-like portion 8 is a plate-like member extending in the horizontal direction, the horizontal central portion is gently curved toward the vehicle interior side, and both horizontal end portions are gently curved toward the vehicle interior side, In a state where the connection port 4 is fitted in the through hole H1, the wall is formed around the through hole H1. The lower end portion of the plate-like portion 8 is positioned substantially equal to the lower end portion of the projecting edge portion 7, and the horizontal width of the plate-like portion 8 is substantially equal to the outer peripheral diameter of the downstream portion of the main body portion 6. It has become. One side of the plate-like part 8 projects in the downstream side of the main body part 6, extends from one side lower part of the opening 62 d to one side along the upper end of the plate-like part 8, and One side ridge 81 extending downward along the side end is formed. The one side protrusion 81 protrudes further downstream than the downstream end of the main body 6. Further, on the other side of the plate-like portion 8, it projects to the downstream side of the main body portion 6, extends to the other side along the upper end of the plate-like portion 8 from the other lower side of the opening 62 d, and the other side of the plate-like portion 8. The other side protrusion part 82 extended below along an edge part is formed. Similar to the one-side protruding portion 81, the other-side protruding portion 82 protrudes further downstream than the downstream side of the main body portion 6. The plate-like portion 8 is reinforced by the one side protrusion 81 and the other side protrusion 82.

図1に示すように、継ぎ手部9は、略円筒形状であり、ハウジング部10の底部に、中心軸が左右方向となるように配置されている。継ぎ手部9の内部には、排水孔9aが形成されており、排水口11に繋がっている。   As shown in FIG. 1, the joint portion 9 has a substantially cylindrical shape, and is arranged on the bottom portion of the housing portion 10 so that the central axis is in the left-right direction. A drain hole 9 a is formed inside the joint portion 9 and is connected to the drain port 11.

排水管5は、ホース部51と、ホースバンド部52とから構成されている。ホース部51の上流端は、継ぎ手部9に差し込まれ、ホース部51の下流端は、接続口部4における本体部6の上流端に繋がっている。   The drain pipe 5 is composed of a hose part 51 and a hose band part 52. The upstream end of the hose part 51 is inserted into the joint part 9, and the downstream end of the hose part 51 is connected to the upstream end of the main body part 6 in the connection port part 4.

ホースバンド部52は、ホース部51を継ぎ手部9から抜け出ないようにホース部51の外周を締め付ける部材であり、略円状の断面がホース部51の中心線方向に延びる形状をしている。   The hose band portion 52 is a member that tightens the outer periphery of the hose portion 51 so that the hose portion 51 does not come out of the joint portion 9, and has a substantially circular cross section extending in the center line direction of the hose portion 51.

次に、接続口部4のフロアーパネルB2への取り付けについて説明する。まず、図5に示すように、接続口部4を貫通穴H1に嵌合する際、接続口部4の開口部62dが上向きとなるように、接続口部4を傾け、貫通穴H1に、接続口部4の板状部8を挿入する。このとき、板状部8は、水平方向両端部が緩やかに湾曲しているので、板状部8を貫通穴H1にスムーズに通過させることができる。そして、貫通穴H1に、板状部8を差し込みながら、接続口部4の開口部62dが水平に向くように、接続口部4を回転させる。その後、接続口部4を貫通穴H1へ押し込むことによって、第1突起部62aとシール部材71との間にフロアーパネルB2が位置することとなり、同様に、第2突起部62bとシール部材71との間と、第3突起部62cとシール部材71との間にフロアーパネルB2が位置することとなり、接続口部4がフロアーパネルB2の貫通穴H1に嵌合する。   Next, attachment of the connection port 4 to the floor panel B2 will be described. First, as shown in FIG. 5, when fitting the connection port 4 into the through hole H1, the connection port 4 is inclined so that the opening 62d of the connection port 4 faces upward, The plate-like part 8 of the connection port part 4 is inserted. At this time, since both ends in the horizontal direction of the plate-like portion 8 are gently curved, the plate-like portion 8 can be smoothly passed through the through hole H1. And the connection port part 4 is rotated so that the opening part 62d of the connection port part 4 may turn horizontally, inserting the plate-shaped part 8 in the through-hole H1. Thereafter, by pushing the connection port 4 into the through hole H1, the floor panel B2 is positioned between the first protrusion 62a and the seal member 71. Similarly, the second protrusion 62b, the seal member 71, The floor panel B2 is positioned between the third protrusion 62c and the seal member 71, and the connection port 4 is fitted into the through hole H1 of the floor panel B2.

次に、車両用空調装置1において発生した凝縮水の排水について説明する。図1に示すように、ハウジング部10内に収容されている冷却用熱交換器2に空気を通過させると、空気中に含まれる水分が凝縮することにより凝縮水が生じ、冷却用熱交換器2より凝縮水が落下する。冷却用熱交換器2より落下した凝縮水は、ハウジング部10の底部に集まり、このハウジング部10の底部において、最下部に設けられた排水口11から排水される。凝縮水は、排水口11に繋がる継ぎ手部9と、ホース部51との内部を通過し、ホース部51に繋がる接続口部4の連通孔63を通って、開口部62dから車室外へと排水される。このとき、開口部62dの周縁下部には、板状部8が形成されているので、凝縮水は、板状部8上を流れて排水されるようになっている。よって、図6に示すように、接続口部4と貫通穴H1との嵌合が不十分な嵌合状態である際、フロアーパネルB2が、突起部62a〜62cとシール部材71との間に無く、板状部8と突起部62a〜62cとの間にある場合であっても、板状部8は、上記貫通穴H1の車室外側開口周縁下部に接触して上記接続口部4が上記貫通穴H1から抜け出るのを規制して車室外に位置するので、凝縮水は、開口部62dから板状部8上を流れて、車室外へ流れ出るのであって車室内に流れ込まない。   Next, drainage of condensed water generated in the vehicle air conditioner 1 will be described. As shown in FIG. 1, when air is passed through the cooling heat exchanger 2 accommodated in the housing portion 10, condensed water is generated due to condensation of moisture contained in the air, and the cooling heat exchanger Condensate falls from 2. The condensed water dropped from the cooling heat exchanger 2 gathers at the bottom of the housing part 10 and is drained from a drain port 11 provided at the bottom of the housing part 10. Condensed water passes through the joint portion 9 connected to the drain port 11 and the hose portion 51, passes through the communication hole 63 of the connection port portion 4 connected to the hose portion 51, and drains from the opening 62 d to the outside of the vehicle compartment. Is done. At this time, since the plate-like portion 8 is formed at the lower periphery of the opening 62d, the condensed water flows on the plate-like portion 8 and is drained. Therefore, as shown in FIG. 6, when the fitting between the connection port 4 and the through hole H1 is insufficient, the floor panel B2 is located between the protrusions 62a to 62c and the seal member 71. Even if it is a case between the plate-shaped part 8 and the projection parts 62a-62c, the plate-shaped part 8 contacts the vehicle compartment outer side opening periphery lower part of the said through-hole H1, and the said connection port part 4 is. Since it is located outside the vehicle compartment while restricting the escape from the through hole H1, the condensed water flows on the plate-like portion 8 from the opening 62d, flows out of the vehicle compartment, and does not flow into the vehicle interior.

以上より、実施形態による車両用空調装置1によれば、板状部8が、接続口部4において、開口部62dの周縁下部に設けられているので、接続口部4を貫通穴H1に嵌合させたときに、板状部8は、貫通穴H1の下部に位置することとなる。そして、接続口部4と貫通穴H1との嵌合が不十分であっても、板状部8が車室外に位置すれば、凝縮水は板状部8を伝って、車室外へ排水されるようになっている。   As mentioned above, according to the vehicle air conditioner 1 by embodiment, since the plate-shaped part 8 is provided in the peripheral lower part of the opening part 62d in the connection port part 4, the connection port part 4 is fitted to the through-hole H1. When combined, the plate-like portion 8 is located below the through hole H1. And even if the fitting between the connection port portion 4 and the through hole H1 is insufficient, if the plate-like portion 8 is located outside the vehicle compartment, the condensed water is drained outside the vehicle compartment through the plate-like portion 8. It has become so.

また、板状部8における水平方向両端に位置する端部に、一側突条部81と、他側突条部82とが形成されているので、他の物体が板状部8と接触しても、一側突条部81と他側突条部82とによって、物体と接続口部4の開口部62dとの間に空間が形成され、凝縮水を接続口部4の開口部62dから車室外へ排水できなくなることを回避できる。   In addition, since one side protrusion 81 and another side protrusion 82 are formed at the ends of the plate-like part 8 located at both ends in the horizontal direction, other objects come into contact with the plate-like part 8. Even so, a space is formed between the object and the opening 62 d of the connection port 4 by the one-side protrusion 81 and the other-side protrusion 82, and condensed water is discharged from the opening 62 d of the connection port 4. It can be avoided that the vehicle cannot be drained out of the passenger compartment.

また、一側突条部81と他側突条部82とは、板状部8を補強しているので、他の物体が板状部8に接触しても、板状部8が変形しにくくなっている。   Further, since the one-side ridge 81 and the other-side ridge 82 reinforce the plate-like portion 8, even if another object contacts the plate-like portion 8, the plate-like portion 8 is deformed. It has become difficult.

また、板状部8は水平方向両端部が車室外側に湾曲しているので、車体に設けられた貫通穴H1に接続口部4を嵌合する際、板状部8を貫通穴H1に挿入し易く、簡易に接続口部4を車体に嵌合することができる。   Further, since both ends of the plate-like portion 8 are curved outward in the vehicle compartment, when the connection port portion 4 is fitted into the through-hole H1 provided in the vehicle body, the plate-like portion 8 is changed to the through-hole H1. It is easy to insert and the connection port 4 can be easily fitted to the vehicle body.

尚、図7に示す変形例1のように、本体部6において下流部の外周に形成された突起部を、第1突起部62aのみとしてもよい。この場合、接続口部4を貫通穴H1(図4に示す)に挿入した際に、第1突起部62aとシール部材71との間でフロアーパネルB2を嵌合し、板状部8と、シール部材71との間にフロアーパネルB2が位置するようにすることで、接続口部4が貫通穴H1から抜け出ないようにすることができる。   Note that, as in Modification 1 shown in FIG. 7, the protrusion formed on the outer periphery of the downstream portion in the main body 6 may be the first protrusion 62a alone. In this case, when the connection port 4 is inserted into the through hole H1 (shown in FIG. 4), the floor panel B2 is fitted between the first protrusion 62a and the seal member 71, By allowing the floor panel B2 to be positioned between the sealing member 71 and the sealing member 71, the connection port portion 4 can be prevented from coming out of the through hole H1.
