Description

空調用ダクト装置Air conditioning duct device
　本発明は、車両で使用される空調用ダクト装置に関し、特に、空気吹出用のレジスタで発生した水滴による不具合を防止する空調用ダクト装置に関する。 The present invention relates to an air-conditioning duct device used in a vehicle, and more particularly to an air-conditioning duct device that prevents a malfunction due to water droplets generated in an air blowing register.
　車両に設けられる空気吹出用のレジスタは、空調用ダクトの先端に接続され、使用されるが、レジスタのケーシングとなるリテーナ内に、冷却された冷房用空気が流れると、リテーナが冷却され、リテーナの壁部で結露が発生し、そこに水滴が生じやすい。リテーナの外側壁面で水滴が発生すると、その水滴は、そのまま下に落下しやすく、レジスタの下側に電子部品が位置するような場合、水滴による電子部品への悪影響を防止する必要がある。 The air blowing register provided in the vehicle is connected to the tip of the air conditioning duct and used, but when cooled cooling air flows into the retainer that serves as the casing of the register, the retainer is cooled and the retainer is used. Condensation forms on the walls of the air conditioner, and water droplets are likely to form there. When water droplets are generated on the outer wall surface of the retainer, the water droplets easily fall down as they are, and when the electronic component is located under the register, it is necessary to prevent the water droplet from adversely affecting the electronic component.
　そこで、例えば、下記特許文献１に記載されるように、レジスタのベゼルの下部延設部に、水滴用リブを設け、この水滴用リブにより、リテーナの外壁面で結露した水滴がベゼルの下部延設部の落下したとき、その水滴を水滴用リブで受けて、電気部品から外れた位置に誘導して流すようにした構造が知られている。 Therefore, for example, as described in Patent Document 1 below, a rib for water droplets is provided on the lower extension portion of the bezel of the register, and the water droplets condensed on the outer wall surface of the retainer are spread on the lower part of the bezel by the rib for water droplets. It is known that when the installation part falls, the water droplets are received by the water droplet ribs and guided to a position away from the electrical parts to flow.
　しかし、この構造では、レジスタのベゼルの下部延設部に、水滴用リブを設けるため、ベゼルの下部延設部を有しないレジスタには、適用することができず、使用できるレジスタが限定され、各種のレジスタに適用できる構造のダクト装置が要望されていた。 However, in this structure, since the rib for water droplets is provided in the lower extension portion of the bezel of the register, it cannot be applied to the register having no lower extension portion of the bezel, and the registers that can be used are limited. There has been a demand for a duct device having a structure applicable to various registers.
実用新案登録第３１６８２７６号Utility model registration No. 3168276
　また、図１０に示す構造のレジスタにおいて、リテーナ４１の下側外壁面に発泡ウレタンシート４２を取着して、リテーナ４１の外壁面で結露を抑制し、且つ発生した水滴を発泡ウレタンシート４２で吸水させる構造も採用されている。しかし、発泡ウレタンシート４２をリテーナ４１の外壁面に貼り付ける作業は、煩雑で、部品点数や部品の取付工数も増し、製造コストを増大させるという課題があった。 Further, in the register having the structure shown in FIG. 10, a urethane foam sheet 42 is attached to the lower outer wall surface of the retainer 41 to suppress dew condensation on the outer wall surface of the retainer 41, and the generated water droplets are collected by the urethane foam sheet 42. A structure that absorbs water is also adopted. However, the work of attaching the urethane foam sheet 42 to the outer wall surface of the retainer 41 is complicated, and there is a problem that the number of parts and the man-hours for attaching the parts are increased, and the manufacturing cost is increased.
　本発明は、上述の課題を解決するものであり、簡単な構造で、レジスタで発生した水滴をダクト側で溜めて、水滴の他への影響を、安価に防止することができる空調用ダクト装置を提供することを目的とする。 The present invention solves the above-mentioned problems, and has a simple structure, and can collect water droplets generated in a register on the duct side and prevent the influence of water droplets on other parts at low cost. The purpose is to provide.
　本発明に係る空調用ダクト装置は、ダクト本体と、該ダクト本体の下流側の先端に設けられ、先端開口を有する接続部と、該接続部の下部に設けた水滴受け溜め部と、を備え、レジスタのリテーナの上流側に設けられた挿入接続部が、該先端開口から該接続部内に挿入され、該接続部は、該リテーナの該挿入接続部を覆う形状に形成され、該水滴受け溜め部は、該挿入接続部の壁部外面に生じた水滴を受けて溜めることを特徴とする。 The air-conditioning duct device according to the present invention includes a duct main body, a connecting portion provided at the downstream end of the duct main body and having a tip opening, and a water droplet receiving portion provided at the lower portion of the connecting portion. An insertion connection portion provided on the upstream side of the retainer of the register is inserted into the connection portion through the tip opening, and the connection portion is formed in a shape covering the insertion connection portion of the retainer to collect water droplets. The portion is characterized in that it receives and collects water droplets generated on the outer surface of the wall portion of the insertion connection portion.
　この発明によれば、レジスタのリテーナの壁部外面で結露した水滴は、ダクト装置の接続部の下部に設けた水滴受け溜め部に入り、溜められるので、その下方に電気部品が位置する場合でも、水滴による悪影響を、簡単な構造により、低コストで防止することができる。 According to the present invention, the water droplets condensed on the outer surface of the wall portion of the retainer of the register enter and be collected in the water droplet receiving portion provided at the lower part of the connection portion of the duct device, so that even if the electric component is located below the water droplet receiving portion. , The adverse effect of water droplets can be prevented at low cost by a simple structure.
　ここで、上記ダクト本体の接続部及び水滴受け溜め部は、先端開口を上方に上げるように、ダクト通風軸線に対し、所定の前方上方傾斜角だけ上方に傾斜した構成とすることができる。これによれば、水滴受け溜め部で受けた水滴の保持性が向上する。 Here, the connecting portion and the water droplet receiving portion of the duct body can be configured to be inclined upward by a predetermined forward upward inclination angle with respect to the duct ventilation axis so as to raise the tip opening upward. According to this, the holding property of the water droplet received in the water droplet receiving portion is improved.
　ここで、上記水滴受け溜め部は、トレー状底面を有し、該トレー状底面の両側に両側傾斜面が設けられ、先端側に先端側傾斜面を設けて構成することが好ましい。これによれば、簡単な構造により、水滴受け溜め部で受けた水滴の保持性を向上させることができる。 Here, it is preferable that the water droplet receiving portion has a tray-shaped bottom surface, both sides of the tray-shaped bottom surface are provided with inclined surfaces, and the tip side is provided with inclined surfaces on the tip side. According to this, it is possible to improve the retention of water droplets received at the water droplet receiving portion by a simple structure.
　またここで、上記水滴受け溜め部は、上記ダクト本体の接続部の垂直断面から前方に突き出す形状に延長して形成することが好ましい。これによれば、レジスタのリテーナの挿入接続部をダクト本体の接続部に挿入する際、容易に挿入することができる。 Further, here, it is preferable that the water droplet receiving portion is formed so as to extend forward from the vertical cross section of the connecting portion of the duct body. According to this, when the insertion connection portion of the retainer of the register is inserted into the connection portion of the duct main body, it can be easily inserted.
　またここで、上記水滴受け溜め部の底面に凹凸部を設けることができる。これによれば、水滴受け溜め部に溜まった水滴の蒸発を促進させることができる。 Also, here, an uneven portion can be provided on the bottom surface of the water droplet receiving portion. According to this, it is possible to promote the evaporation of the water droplets accumulated in the water droplet receiving portion.
　またここで、上記ダクト本体、接続部及び水滴受け溜め部は、合成樹脂により一体成形することができる。これによれば、部品点数を増すことなく、低コストで水滴対策をダクト装置に施すことができる。 Also, here, the duct body, the connecting portion, and the water droplet receiving portion can be integrally molded with synthetic resin. According to this, it is possible to take measures against water droplets on the duct device at low cost without increasing the number of parts.
　この発明の空調用ダクト装置によれば、レジスタで発生した水滴を、水滴受け溜め部に溜めて、他への影響を簡単な構造で安価に防止することができる。 According to the air-conditioning duct device of the present invention, water droplets generated in the register can be accumulated in the water droplet receiving portion, and the influence on others can be prevented at low cost with a simple structure.

The connecting portion 2 on the tip side is provided with a tip opening 4 for inserting and connecting the retainer 11.
　ダクト本体１の接続部２は、レジスタ１０のリテーナ１１に設けた挿入接続部１９を覆う形状に形成され、図５に示す如く、リテーナ１１の挿入接続部１９が先端開口４から接続部２内に挿入されて接続される。また、接続部２の下部に、挿入接続部１９の壁部外面に生じた水滴を受ける水滴受け溜め部３が設けられる。 The connection portion 2 of the duct body 1 is formed so as to cover the insertion connection portion 19 provided in the retainer 11 of the register 10, and as shown in FIG. 5, the insertion connection portion 19 of the retainer 11 is formed from the tip opening 4 into the connection portion 2. It is inserted into and connected. Further, a water droplet receiving portion 3 for receiving water droplets generated on the outer surface of the wall portion of the insertion connecting portion 19 is provided below the connecting portion 2.
　ダクト本体１の接続部２の下部（底部）に設けた水滴受け溜め部３は、図３、図５に示すように、トレー状底面８を有してトレー状に形成され、トレー状底面８の両側に両側傾斜面６が設けられ、先端側に先端側傾斜面７を設けて構成される。また、水滴受け溜め部３は、図５に示す如く、ダクト本体１の接続部２の垂直断面Ａから前方に突き出す形状に形成され、これにより、先端開口４は斜めに傾斜している。 As shown in FIGS. 3 and 5, the water droplet receiving portion 3 provided at the lower portion (bottom portion) of the connecting portion 2 of the duct main body 1 has a tray-shaped bottom surface 8 and is formed in a tray shape, and the tray-shaped bottom surface 8 is formed. Both side inclined surfaces 6 are provided on both sides of the above, and the tip side inclined surfaces 7 are provided on the tip side. Further, as shown in FIG. 5, the water droplet receiving portion 3 is formed in a shape protruding forward from the vertical cross section A of the connecting portion 2 of the duct main body 1, whereby the tip opening 4 is obliquely inclined.
　また、ダクト本体１の接続部２は、図５に示す如く、先端開口４を上方に上げるように、ダクト通風軸線Ｈ１に対し、前方上方傾斜角αだけ上方に傾斜して形成される。つまり、ダクト通風軸線Ｈ１は、ダクト本体１の通風路内の、通風方向に沿った軸線であり、接続部２の軸線Ｈ２はダクト通風軸線Ｈ１に対し前方上方傾斜角αで斜め上向きに傾斜している。 Further, as shown in FIG. 5, the connecting portion 2 of the duct main body 1 is formed so as to be inclined upward by a forward upward inclination angle α with respect to the duct ventilation axis H1 so as to raise the tip opening 4 upward. That is, the duct ventilation axis H1 is an axis along the ventilation direction in the ventilation path of the duct main body 1, and the axis H2 of the connecting portion 2 is inclined diagonally upward with a forward upward inclination angle α with respect to the duct ventilation axis H1. ing.
　図５に示すように、水滴受け溜め部３は、ダクト本体１の接続部２に設けられ、水滴受け溜め部３は、接続部２とともに、前方上方傾斜角αだけ上側に傾斜している。このため、水滴受け溜め部３のトレー状底面８も、その前部が水平面に対し前方上方傾斜角αだけ上側に傾斜している。これにより、図５に示す如く、レジスタ１０のリテーナ１１の外壁に生じる水滴が落下したとき、水滴受け溜め部３でそれを受け、水滴をそこに溜めて保持する。 As shown in FIG. 5, the water droplet receiving portion 3 is provided in the connecting portion 2 of the duct main body 1, and the water droplet receiving portion 3 is inclined upward by the forward upward inclination angle α together with the connecting portion 2. Therefore, the tray-shaped bottom surface 8 of the water droplet receiving portion 3 also has its front portion inclined upward by a forward upward inclination angle α with respect to the horizontal plane. As a result, as shown in FIG. 5, when water droplets generated on the outer wall of the retainer 11 of the register 10 fall, they are received by the water droplet receiving portion 3 and the water droplets are accumulated and held there.
　一方、レジスタ１０は、図５に示すように、筒状に形成されたリテーナ１１の下流側前部内側に、回動ルーバー１２を取り付けて構成され、上流側の通風路１１ａ内にダンパプレート１７が通風路を開閉可能に、両側の支軸を介して軸支される。回動ルーバー１２は、後部上流側に後可動フィン１４を配設し、前部下流側に前可動フィン１３を配設し、前可動フィン１３と後可動フィン１４は相互に直交する方向に配設され、クロスフィン型の回動ルーバー１２を成している。 On the other hand, as shown in FIG. 5, the register 10 is configured by attaching a rotating louver 12 to the inside of the downstream front portion of the retainer 11 formed in a tubular shape, and the damper plate 17 is formed in the ventilation passage 11a on the upstream side. Can open and close the ventilation passage, and is pivotally supported via the support shafts on both sides. In the rotating louver 12, the rear movable fin 14 is arranged on the rear upstream side, the front movable fin 13 is arranged on the front downstream side, and the front movable fin 13 and the rear movable fin 14 are arranged in the directions orthogonal to each other. It is provided to form a cross-fin type rotating louver 12.
　後可動フィン１４は、複数の後フィン１４ａを縦に配置し、且つ上部と下部に設けた支軸を介して各後フィン１４ａを左右に回動可能に軸支し、横方向にそれらの後フィン１４ａを並設して構成される。前可動フィン１３は、後フィン１４ａと直交する方向に複数の前フィン１３ａを配置し且つ左右両側に設けた支軸を介して各前フィン１３ａを、上下に回動可能に軸支し、縦方向にそれらを並設して構成される。 The rear movable fins 14 have a plurality of rear fins 14a arranged vertically, and each rear fin 14a is rotatably supported on the left and right via support shafts provided at the upper and lower portions, and the rear fins 14a are laterally supported. The fins 14a are arranged side by side. The front movable fins 13 have a plurality of front fins 13a arranged in a direction orthogonal to the rear fins 14a, and each front fin 13a is rotatably supported vertically via support shafts provided on both the left and right sides. They are arranged side by side in the direction.
　前フィン１３ａには、操作ノブ１６が前フィン１３ａの長手方向に摺動可能に取り付けられ、操作ノブ１６の後部に設けた係合脚部が後フィン１４ａと係合する。これにより、操作ノブ１６を前フィン１３ａ上で左右に摺動操作したとき、後フィン１４ａが左右に回動し、操作ノブ１６を上下に操作すると、前フィン１３ａが上下に回動し、風向を左右に或いは上下に変えることができる。 An operation knob 16 is slidably attached to the front fin 13a in the longitudinal direction of the front fin 13a, and an engaging leg portion provided at the rear portion of the operation knob 16 engages with the rear fin 14a. As a result, when the operation knob 16 is slid left and right on the front fin 13a, the rear fin 14a rotates left and right, and when the operation knob 16 is operated up and down, the front fin 13a rotates up and down and the wind direction. Can be changed left and right or up and down.
　図５に示す如く、レジスタ１０のリテーナ１１の上流側に、上流側開口部１８を有する挿入接続部１９が形成され、挿入接続部１９は、ダクト本体１の先端に設けた接続部２の先端開口４を通して、接続部２内に挿入して接続される。レジスタ１０の挿入接続部１９とダクト本体１の接続部２との間に、発泡ウレタンなどが隙間を埋めるように介挿される。 As shown in FIG. 5, an insertion connection portion 19 having an upstream opening 18 is formed on the upstream side of the retainer 11 of the register 10, and the insertion connection portion 19 is the tip of the connection portion 2 provided at the tip of the duct body 1. It is inserted into and connected to the connecting portion 2 through the opening 4. Urethane foam or the like is inserted between the insertion connection portion 19 of the register 10 and the connection portion 2 of the duct body 1 so as to fill a gap.
　なお、ダクト本体１、接続部２及び水滴受け溜め部３は、合成樹脂材料を用いた押出ブロー成形、押出発泡ブロー成形などにより、一体成形することができる。これにより、部品点数を増やすことなく、低コストで、水滴受け溜め部３を設けることができる。 The duct body 1, the connecting portion 2, and the water droplet receiving portion 3 can be integrally molded by extrusion blow molding, extrusion foam blow molding, or the like using a synthetic resin material. As a result, the water droplet receiving portion 3 can be provided at low cost without increasing the number of parts.
　次に、上記構成の空調用ダクト装置とレジスタの動作を説明する。空調装置の動作時、そこから供給される空気流は、ダクト本体１の上流側接続部５からダクト内に送られる。ダクト本体１内に送られた空気流は、接続部２を通して、リテーナ１１の上流側開口部１８からレジスタ１０内に入り、ダンパプレート１７から回動ルーバー１２を通過して、ベゼル１５の空気吹出口から前方に送風される。 Next, the operation of the air conditioning duct device and the register having the above configuration will be described. When the air conditioner operates, the air flow supplied from the air conditioner is sent into the duct from the upstream connection portion 5 of the duct main body 1. The air flow sent into the duct body 1 enters the register 10 through the upstream opening 18 of the retainer 11 through the connecting portion 2, passes through the rotating louver 12 from the damper plate 17, and blows air from the bezel 15. The air is blown forward from the exit.
　空調装置で冷却された冷房空気が、ダクト本体１からレジスタ１０に送られると、レジスタ１０のリテーナ１１内を冷気が通過する際、リテーナ１１の壁部が冷却される。梅雨の時期などにこの状態が続くと、リテーナ１１の壁部外面に結露が発生し、水滴が壁部外面に付着する。 When the cooling air cooled by the air conditioner is sent from the duct body 1 to the register 10, the wall portion of the retainer 11 is cooled when the cold air passes through the retainer 11 of the register 10. If this condition continues during the rainy season or the like, dew condensation will occur on the outer surface of the wall portion of the retainer 11, and water droplets will adhere to the outer surface of the wall portion.
　付着した水滴の量が多くなると、リテーナ１１の壁部外面から水滴が落下するが、ダクト本体１の接続部２の底部に水滴受け溜め部３が位置するため、水滴はその水滴受け溜め部３で受けられ、そのトレー状底面８内に溜められる。このとき、水滴受け溜め部３には、トレー状底面８の両側に両側傾斜面６が設けられ、先端側に先端側傾斜面７を設けられるため、リテーナ１１の壁部外面で発生した水滴は、全て効果的に水滴受け溜め部３に入り、そこに溜まることとなる。 When the amount of attached water droplets increases, water droplets fall from the outer surface of the wall portion of the retainer 11, but since the water droplet reservoir portion 3 is located at the bottom of the connection portion 2 of the duct main body 1, the water droplets are the water droplet reservoir portion 3 It is received by and stored in the tray-shaped bottom surface 8. At this time, since the water droplet receiving portion 3 is provided with the inclined surfaces 6 on both sides of the tray-shaped bottom surface 8 and the inclined surfaces 7 on the tip side on the tip side, the water droplets generated on the outer surface of the wall portion of the retainer 11 are provided. , All effectively enter the water droplet receiving part 3 and collect there.
　また、図５に示すように、ダクト本体１は、その接続部２が水平面に対し上側に前方上方傾斜角αだけ傾斜するため、その接続部２に設けた水滴受け溜め部３も、その前部先端側が上側に傾斜して配設される。さらに、水滴受け溜め部３の前部先端側に先端側傾斜面７が設けられるため、水滴受け溜め部３に溜められた水滴は、下方に落ちたり、飛散することはなく、その下方に電気部品が位置する場合でも、水滴による悪影響を、簡単な構造により、低コストで防止することができる。 Further, as shown in FIG. 5, since the connecting portion 2 of the duct main body 1 is inclined upward by the forward upward inclination angle α with respect to the horizontal plane, the water droplet receiving portion 3 provided in the connecting portion 2 is also in front of the duct main body 1. The tip side of the portion is arranged so as to be inclined upward. Further, since the tip side inclined surface 7 is provided on the front tip side of the water droplet receiving portion 3, the water droplets collected in the water droplet receiving portion 3 do not fall or scatter downward, and electricity is generated below the water droplet receiving portion 3. Even when the component is located, the adverse effect of water droplets can be prevented at low cost by a simple structure.
　なお、図７に示すように、水滴受け溜め部２３の底面に凹凸部２４を設けることもできる。底面に凹凸部２４を設けることにより、水滴受け溜め部２３の底面の表面積が増大し、水滴受け溜め部２３に溜まった水を、短時間で蒸発させることができる。 As shown in FIG. 7, an uneven portion 24 can be provided on the bottom surface of the water droplet receiving portion 23. By providing the uneven portion 24 on the bottom surface, the surface area of the bottom surface of the water droplet receiving portion 23 is increased, and the water accumulated in the water droplet receiving portion 23 can be evaporated in a short time.
　また、図８に示すように、水滴受け溜め部３１は、先端側傾斜面を設けない構造とすることもできる。この場合、図８に示す如く、接続部２の軸線Ｈ２がダクト本体１のダクト通風軸線Ｈ１に対し前方上方傾斜角度αで傾斜するため、水滴受け溜め部３１及びトレー状底面３２も、ダクト通風軸線Ｈ１に対し、前方上方傾斜角度αだけ傾斜する。このため、水滴受け溜め部３１は、水滴を受けて溜めることができる。 Further, as shown in FIG. 8, the water droplet receiving portion 31 may have a structure in which the tip side inclined surface is not provided. In this case, as shown in FIG. 8, since the axis H2 of the connecting portion 2 is inclined at a forward upward inclination angle α with respect to the duct ventilation axis H1 of the duct main body 1, the water droplet receiving portion 31 and the tray-shaped bottom surface 32 are also duct ventilated. It is tilted forward and upward by an upward tilt angle α with respect to the axis H1. Therefore, the water droplet receiving unit 31 can receive and store the water droplets.
　図９は、第２実施形態の空調用ダクト装置を示している。このダクト装置は、ダクト本体１の接続部２、水滴受け溜め部３０及びトレー状底面３８が、ダクト通風軸線Ｈ１と平行に形成され、その他の部分の構造は、上記実施形態と同様である。つまり、ダクト本体１の上流側部分と下流側の接続部２は、図９に示す如く、共にダクト通風軸線Ｈ１と平行に形成される。上記実施形態と同様の箇所については、図９に上記と同じ符号を付してその説明は省略する。 FIG. 9 shows the air conditioning duct device of the second embodiment. In this duct device, the connecting portion 2, the water droplet receiving portion 30, and the tray-shaped bottom surface 38 of the duct main body 1 are formed in parallel with the duct ventilation axis H1, and the structure of other portions is the same as that of the above embodiment. That is, as shown in FIG. 9, both the upstream side portion and the downstream side connecting portion 2 of the duct main body 1 are formed parallel to the duct ventilation axis H1. The same parts as those in the above embodiment are designated by the same reference numerals as those described above in FIG. 9, and the description thereof will be omitted.
　ダクト本体１の接続部２は、図９に示す如く、レジスタ１０のリテーナ１１に設けた挿入接続部１９を覆う形状に形成され、リテーナ１１の挿入接続部１９が先端開口４から接続部２内に挿入されて接続される。また、接続部２の下部に、挿入接続部１９の壁部外面に生じた水滴を受ける水滴受け溜め部３０が設けられる。 As shown in FIG. 9, the connection portion 2 of the duct body 1 is formed so as to cover the insertion connection portion 19 provided in the retainer 11 of the register 10, and the insertion connection portion 19 of the retainer 11 is formed from the tip opening 4 into the connection portion 2. It is inserted into and connected. Further, a water droplet receiving portion 30 for receiving water droplets generated on the outer surface of the wall portion of the insertion connecting portion 19 is provided below the connecting portion 2.
　ダクト本体１の接続部２の下部（底部）に設けた水滴受け溜め部３０は、図９に示すように、トレー状底面３８を有してトレー状に形成され、トレー状底面３８の両側に両側傾斜面が設けられ、先端側に先端側傾斜面３７が設けられる。また、水滴受け溜め部３０は、ダクト本体１の接続部２の垂直断面Ａから前方に突き出す形状に形成される。ダクト本体１の接続部２、水滴受け溜め部３０及びトレー状底面３８は、図９に示す如く、ダクト通風軸線Ｈ１と平行に形成される。 As shown in FIG. 9, the water droplet receiving portion 30 provided at the lower portion (bottom portion) of the connecting portion 2 of the duct main body 1 has a tray-shaped bottom surface 38 and is formed in a tray shape, and is formed on both sides of the tray-shaped bottom surface 38. Both side inclined surfaces are provided, and the tip side inclined surface 37 is provided on the tip side. Further, the water droplet receiving portion 30 is formed in a shape protruding forward from the vertical cross section A of the connecting portion 2 of the duct main body 1. As shown in FIG. 9, the connecting portion 2, the water droplet receiving portion 30, and the tray-shaped bottom surface 38 of the duct main body 1 are formed in parallel with the duct ventilation axis H1.
　レジスタ１０は、リテーナ１１の挿入接続部１９が、ダクト本体１の先端開口４から接続部２内に挿入されて接続され、リテーナ１１内の通風路の通風方向が、ダクト通風軸線Ｈ１と平行になるように、レジスタ１０とダクト本体１は接続される。 The register 10 is connected by inserting the insertion connection portion 19 of the retainer 11 into the connection portion 2 through the tip opening 4 of the duct body 1, and the ventilation direction of the ventilation path in the retainer 11 is parallel to the duct ventilation axis H1. The register 10 and the duct body 1 are connected so as to be.
　上記構成の空調用ダクト装置は、例えば、車両の内部に、水平状態で設置され、レジスタ１０のリテーナ１１の挿入接続部１９が、ダクト本体１の接続部２の先端開口４から内部に挿入接続され、車室内に水平に取り付けられる。 The air-conditioning duct device having the above configuration is installed, for example, in a horizontal state inside the vehicle, and the insertion connection portion 19 of the retainer 11 of the register 10 is inserted and connected to the inside from the tip opening 4 of the connection portion 2 of the duct body 1. It is installed horizontally in the passenger compartment.
　空調装置で冷却された冷房空気が、ダクト本体１からレジスタ１０に送られると、レジスタ１０のリテーナ１１内を冷気が通過する際、リテーナ１１の壁部が冷却される。梅雨の時期などにこの状態が続くと、リテーナ１１の壁部外面に結露が発生し、水滴が壁部外面に付着する。 When the cooling air cooled by the air conditioner is sent from the duct body 1 to the register 10, the wall portion of the retainer 11 is cooled when the cold air passes through the retainer 11 of the register 10. If this condition continues during the rainy season or the like, dew condensation will occur on the outer surface of the wall portion of the retainer 11, and water droplets will adhere to the outer surface of the wall portion.
　付着した水滴の量が多くなると、リテーナ１１の壁部外面から水滴が落下するが、ダクト本体１の接続部２の底部に水滴受け溜め部３０が位置するため、水滴はその水滴受け溜め部３０で受けられ、そのトレー状底面３８内に溜められる。このとき、水滴受け溜め部３０のトレー状底面３８は、ダクト通風軸線Ｈ１と平行であるが、先端側に先端側傾斜面３７を設けられるため、リテーナ１１の壁部外面で発生した水滴は、水滴受け溜め部３０に入り、流出することなく、そこに溜まる。 When the amount of attached water droplets increases, water droplets fall from the outer surface of the wall portion of the retainer 11, but since the water droplet reservoir portion 30 is located at the bottom of the connection portion 2 of the duct main body 1, the water droplets are collected by the water droplet reservoir portion 30. It is received by and stored in the tray-shaped bottom surface 38. At this time, the tray-shaped bottom surface 38 of the water droplet receiving portion 30 is parallel to the duct ventilation axis H1, but since the distal end side inclined surface 37 is provided on the distal end side, the water droplets generated on the outer surface of the wall portion of the retainer 11 can be collected.
