<Outline configuration of outlet device>
FIG. 1 is a perspective view showing an outline of the outlet device 1 according to the embodiment. Further, FIG. 2 is a side view showing the inside of the outer cylinder 2 in a concentrated state. The air outlet device 1 is provided, for example, in the instrument panel of a vehicle, the central part of the front seat, or the like toward the rear, and adjusts the wind direction, air volume, concentration, diffusion, etc. of the air flowing in from a ventilation source such as an air conditioner. It is a device that blows air into the passenger compartment. The outlet device 1 includes an outer cylinder 2, an inner cylinder 3 arranged inside the outer cylinder 2, an adjusting mechanism 4 provided inside the outer cylinder 2 and upstream of the inner cylinder 3 in the blowing direction. It has a throttle opening 5 provided at the downstream end of the outer cylinder 2 in the blowing direction, and an inner cylinder moving mechanism 6 capable of moving the inner cylinder 3 in the axial direction. In the present embodiment, the blowing direction is the traveling direction of the air flowing into the outer cylinder 2, and corresponds to the axial direction of the outer cylinder 2. Hereinafter, the upstream in the blowing direction and the downstream in the blowing direction may be simply referred to as upstream and downstream.

本実施形態の場合、吹出口装置1は、外筒2に流入した空気を集中して吹き出す集中状態と、拡散して吹き出す拡散状態とを有している。集中状態では、運転者のハンドルの把持位置等、車室内の所望の場所にピンポイントで空気を集中させることができる。一方、拡散状態では、車室内全体の温度を下げたいときや乗員が全身で風を浴びたいとき等、車室内の広範囲に空気を拡散させることができる。なお、本実施形態では、集中状態及び拡散状態は、いずれかの状態にオン・オフ的に切り替わるのではなく、吹出される空気が最も集中した状態から最も拡散した状態にかけて連続的に変化する。しかしながら、集中状態及び拡散状態の二つの状態にオン・オフ的に切り替わる構成や、集中状態及び拡散度合いの異なる複数の拡散状態を有し、これらの状態に段階的に切り替わる構成も採用可能である。 In the case of the present embodiment, the outlet device 1 has a concentrated state in which the air flowing into the outer cylinder 2 is concentrated and blown out, and a diffusion state in which the air flowing into the outer cylinder 2 is diffused and blown out. In the concentrated state, the air can be pinpointed to a desired location in the vehicle interior, such as the gripping position of the driver's steering wheel. On the other hand, in the diffused state, the air can be diffused over a wide range in the vehicle interior, such as when the temperature of the entire vehicle interior is to be lowered or when the occupant wants to be exposed to the wind with the whole body. In the present embodiment, the concentrated state and the diffused state do not switch on / off to either state, but continuously change from the most concentrated state to the most diffused state of the blown air. However, it is also possible to adopt a configuration in which the two states of the concentrated state and the diffused state are switched on and off, and a configuration in which the concentrated state and a plurality of diffused states having different degrees of diffusion are switched in stages. ..

本実施形態では、吹出口装置1は、内筒3、調整機構4、絞り開口部5及び内筒移動機構6が連動して作動することにより、吹き出される空気の状態を集中状態と拡散状態との間で変化させる。これらの構成について、以下で説明する。 In the present embodiment, the outlet device 1 operates in conjunction with the inner cylinder 3, the adjusting mechanism 4, the throttle opening 5, and the inner cylinder moving mechanism 6, so that the state of the air blown out is in a concentrated state and a diffused state. Change between. These configurations will be described below.

外筒2は、吹出口装置1の外形を画定する筒状の部材である。送風源から供給された空気は、上流側開口2aから外筒2の内部に流入し、下流側開口2bから外筒2の外部へと吹き出される。 The outer cylinder 2 is a tubular member that defines the outer shape of the outlet device 1. The air supplied from the blower source flows into the outer cylinder 2 from the upstream opening 2a and is blown out from the downstream opening 2b to the outside of the outer cylinder 2.

本実施形態では外筒2は円筒形状を有しているが、円筒形状の他、楕円や多角形等の筒状形状を有していてもよい。また、本実施形態では上流側開口2aから下流側開口2bにかけて外筒2の内径は一定であるが、位置に応じて内径が異なる構成も採用可能である。例えば外筒2は樹脂材料により一体成型される。また、例えば外筒2は金属材料により形成される。 In the present embodiment, the outer cylinder 2 has a cylindrical shape, but it may have a cylindrical shape such as an ellipse or a polygon in addition to the cylindrical shape. Further, in the present embodiment, the inner diameter of the outer cylinder 2 is constant from the upstream opening 2a to the downstream opening 2b, but a configuration in which the inner diameter differs depending on the position can also be adopted. For example, the outer cylinder 2 is integrally molded with a resin material. Further, for example, the outer cylinder 2 is made of a metal material.

図6を併せて参照する。図6は集中状態における空気の流れを示す模式図であり、吹出口装置1の断面を概略的に示している。外筒2は、その内面22に形成された螺旋状のリブ21を有している。リブ21は、調整機構4よりも下流側において、内筒3を囲むように配置されている。リブ21により外筒2に流入した空気は螺旋状の流れとなって吹き出される。なお、図6等に示したリブ21の螺旋の軸方向に対する傾きは例示であって、空気を螺旋状に流すための適切な傾きが選ばれてよい。 See also FIG. FIG. 6 is a schematic view showing the air flow in a concentrated state, and schematically shows a cross section of the air outlet device 1. The outer cylinder 2 has a spiral rib 21 formed on the inner surface 22 thereof. The rib 21 is arranged on the downstream side of the adjusting mechanism 4 so as to surround the inner cylinder 3. The air that has flowed into the outer cylinder 2 by the rib 21 is blown out as a spiral flow. The inclination of the rib 21 with respect to the axial direction shown in FIG. 6 and the like is an example, and an appropriate inclination for allowing air to flow in a spiral shape may be selected.

内筒3は、外筒2に流入した空気を集中させるための筒状の部材であり、本実施形態では外筒2の内側に外筒2と同軸で配置されている。外筒2に流入した空気は、内筒3を通過することで、開口3aから吹出方向に直線的に吹き出される。なお、外筒2と内筒3が同軸で配置されるとは、互いの軸中心が一致するものに限らず実質的に同軸である者も含む。例えば、正面視で外筒2の軸中心が内筒3の開口3aを通過するように、外筒2及び内筒3が配置されてもよい。 The inner cylinder 3 is a tubular member for concentrating the air flowing into the outer cylinder 2, and is arranged coaxially with the outer cylinder 2 inside the outer cylinder 2 in the present embodiment. The air that has flowed into the outer cylinder 2 passes through the inner cylinder 3 and is blown out linearly from the opening 3a in the blowing direction. It should be noted that the fact that the outer cylinder 2 and the inner cylinder 3 are arranged coaxially includes not only those having the same axial centers but also those who are substantially coaxial. For example, the outer cylinder 2 and the inner cylinder 3 may be arranged so that the axis center of the outer cylinder 2 passes through the opening 3a of the inner cylinder 3 in front view.

本実施形態では内筒3は円筒形状を有しているが、円筒形状の他、楕円や多角形等の筒状形状を有していてもよい。また、本実施形態では上流側開口2aから下流側開口2bにかけて外筒2の内径は一定であるが、位置に応じて内径が異なる構成も採用可能である。例えば外筒2は樹脂材料により一体成型される。また、例えば外筒2は金属材料により形成される。 In the present embodiment, the inner cylinder 3 has a cylindrical shape, but it may have a cylindrical shape such as an ellipse or a polygon in addition to the cylindrical shape. Further, in the present embodiment, the inner diameter of the outer cylinder 2 is constant from the upstream opening 2a to the downstream opening 2b, but a configuration in which the inner diameter differs depending on the position can also be adopted. For example, the outer cylinder 2 is integrally molded with a resin material. Further, for example, the outer cylinder 2 is made of a metal material.

<調整機構>
調整機構4は、集中状態と拡散状態の間で外筒2に流入した空気の流れを調整可能な機構である。本実施形態では、調整機構4は外筒2の内側、かつ、吹出方向で内筒3よりも上流側に設けられている。
<Adjustment mechanism>
The adjusting mechanism 4 is a mechanism capable of adjusting the flow of air flowing into the outer cylinder 2 between the concentrated state and the diffused state. In the present embodiment, the adjusting mechanism 4 is provided inside the outer cylinder 2 and on the upstream side of the inner cylinder 3 in the blowing direction.

調整機構4は、後述の機構により、集中状態ときは外筒2に流入した空気を内筒3の内側に誘導し、拡散状態のときは外筒2に流入した空気をそのまま吹き出させる。これにより、集中状態のときは、外筒2に流入した空気は内筒3の内側を通過して吹き出されるので、吹出口装置1はより集中した空気を吹き出すことができる。また、本実施形態の場合、内筒3の下流側には操作部等の空気の流れの妨げたなるものが配置されないため、より効果的に集中した空気が吹き出される。一方、拡散状態のときは、外筒2に流入した空気は内筒3の内側及び外側を通過して吹き出されるので、吹出口装置1は集中状態よりも拡散した空気を吹き出すことができる。 The adjusting mechanism 4 guides the air flowing into the outer cylinder 2 to the inside of the inner cylinder 3 in the concentrated state, and blows out the air flowing into the outer cylinder 2 as it is in the diffused state by a mechanism described later. As a result, in the concentrated state, the air flowing into the outer cylinder 2 passes through the inside of the inner cylinder 3 and is blown out, so that the air outlet device 1 can blow out more concentrated air. Further, in the case of the present embodiment, since an operation unit or the like that obstructs the air flow is not arranged on the downstream side of the inner cylinder 3, more effectively concentrated air is blown out. On the other hand, in the diffused state, the air flowing into the outer cylinder 2 passes through the inside and the outside of the inner cylinder 3 and is blown out, so that the outlet device 1 can blow out the diffused air more than in the concentrated state.

図2に併せて図3、図4(A)及び図4(B)を参照する。図3は拡散状態における外筒2の内部を示す側面図である。また、図4(A)は集中状態における吹出口装置1の背面図、図4(B)は拡散状態における吹出口装置の背面図である。図4(A)及び図4(B)は、吹出口装置1を吹出方向の上流側からみた図に相当する。 3 and 4 (A) and 4 (B) are referred to in conjunction with FIG. FIG. 3 is a side view showing the inside of the outer cylinder 2 in the diffusion state. Further, FIG. 4A is a rear view of the outlet device 1 in a concentrated state, and FIG. 4B is a rear view of the outlet device in a diffusion state. 4 (A) and 4 (B) correspond to a view of the outlet device 1 from the upstream side in the blowing direction.

調整機構4は、複数の切替羽根411ないし416を有している。切替羽根411ないし416は、吹出方向に延びた形状をしており、外筒2の内側に周方向にわたってそれぞれ配置されている。また、切替羽根411ないし416は、吹出方向で、それぞれの上流側端部411aないし416aが周方向を軸として回動可能に支持されている。 The adjusting mechanism 4 has a plurality of switching blades 411 to 416. The switching blades 411 to 416 have a shape extending in the blowing direction, and are respectively arranged inside the outer cylinder 2 in the circumferential direction. Further, the switching blades 411 to 416 are supported so that their upstream end portions 411a to 416a are rotatably supported about the circumferential direction in the blowing direction.

本実施形態では、例えば切替羽根411はその上流側端部411aにおいて周方向に互いに離間した回動軸411b及び411cを有しており、回動軸411b及び411cは外筒2の内面22に設けられた受け部221a及び221bにそれぞれ回動可能に支持されている。切替羽根412ないし416も同様の構成を有している。また、本実施形態では6枚の切替羽根411ないし416が外筒2の周方向にわたって配置され、背面視で内筒を取り囲むように配置されているが、切替羽根の枚数は5枚以下又は7枚以上であってもよい。また、本実施形態では受け部221aないし221fは外筒2の上流側開口2aに近接して設けられているが、上流側開口2aよりも下流で外筒2の内面に設けられてもよい。 In the present embodiment, for example, the switching blade 411 has rotating shafts 411b and 411c separated from each other in the circumferential direction at the upstream end portion 411a thereof, and the rotating shafts 411b and 411c are provided on the inner surface 22 of the outer cylinder 2. It is rotatably supported by the receiving portions 221a and 221b, respectively. The switching blades 412 to 416 have a similar configuration. Further, in the present embodiment, six switching blades 411 to 416 are arranged over the circumferential direction of the outer cylinder 2 so as to surround the inner cylinder in the rear view, but the number of switching blades is 5 or less or 7. It may be more than one. Further, in the present embodiment, the receiving portions 221a to 221f are provided close to the upstream opening 2a of the outer cylinder 2, but may be provided on the inner surface of the outer cylinder 2 downstream of the upstream opening 2a.

切替羽根411ないし416は、それぞれの上流側端部411dないし416dにより調整機構4の下流側に空気を導入する導入開口4aを形成する。導入開口4aは、切替羽根411ないし416の回動によりその開口の大きさを連続的に切り替えることができる。 The switching blades 411 to 416 form an introduction opening 4a for introducing air on the downstream side of the adjusting mechanism 4 by the upstream end portions 411d to 416d, respectively. The size of the opening of the introduction opening 4a can be continuously switched by rotating the switching blades 411 to 416.

調整機構4は、複数の切替羽根411ないし416のそれぞれを回動させる複数の開閉アーム421ないし426を有する。開閉アーム421ないし426は内筒3から径方向外側に向かってそれぞれ延び、切替羽根411ないし416にそれぞれ設けられた孔411fないし416fを貫通して設けられている。後述の構成により内筒3が軸方向に移動すると開閉アーム421ないし426もそれに伴って移動し、開閉アーム421ないし426に付勢された切替羽根411ないし416が回動する。つまり、内筒3の軸方向の移動に応じて調整機構4の導入開口4aが変化する。本実施形態の場合、内筒3が上流側に移動すると導入開口4aが大きくなり、下流側に移動すると導入開口4aが小さくなる。なお、内筒3の軸方向の移動は回転体52の回転に応じて生じる。この機構については<内筒移動機構>の欄で詳しく説明する。 The adjusting mechanism 4 has a plurality of opening / closing arms 421 to 426 for rotating each of the plurality of switching blades 411 to 416. The opening / closing arms 421 to 426 extend radially outward from the inner cylinder 3 and are provided through the holes 411f to 416f provided in the switching blades 411 to 416, respectively. When the inner cylinder 3 moves in the axial direction according to the configuration described later, the opening / closing arms 421 to 426 also move accordingly, and the switching blades 411 to 416 urged by the opening / closing arms 421 to 426 rotate. That is, the introduction opening 4a of the adjusting mechanism 4 changes according to the axial movement of the inner cylinder 3. In the case of the present embodiment, when the inner cylinder 3 moves to the upstream side, the introduction opening 4a becomes large, and when the inner cylinder 3 moves to the downstream side, the introduction opening 4a becomes small. The movement of the inner cylinder 3 in the axial direction occurs in response to the rotation of the rotating body 52. This mechanism will be described in detail in the column of <Inner cylinder moving mechanism>.

例えば、図4(A)に示すように、集中状態のときはそれぞれの上流側端部411dないし416dが内筒3を囲むように位置している。そのため、導入開口4aの大きさは内筒3の開口の大きさに対応する(導入開口4a1)。これにより、集中状態のときは、調整機構4は外筒2に流入した空気の大部分(又は全て)を内筒3の内側に誘導することができる。本実施形態では、切替羽根411ないし416は、集中状態においてそれらの側端部と隣接する切替羽根の側端部とが互いに離間するように設けられている。しかしながら、切替羽根411ないし416が、集中状態においてそれらの側端部と隣接する切替羽根の側端部とが互いに当接、あるいは重複するように設けられてもよい。 For example, as shown in FIG. 4 (A), in the concentrated state, the respective upstream end portions 411d to 416d are located so as to surround the inner cylinder 3. Therefore, the size of the introduction opening 4a corresponds to the size of the opening of the inner cylinder 3 (introduction opening 4a1). As a result, in the concentrated state, the adjusting mechanism 4 can guide most (or all) of the air flowing into the outer cylinder 2 to the inside of the inner cylinder 3. In the present embodiment, the switching blades 411 to 416 are provided so that their side ends and the side ends of the adjacent switching blades are separated from each other in a concentrated state. However, the switching blades 411 to 416 may be provided so that their side ends and the side ends of the adjacent switching blades are in contact with each other or overlap each other in a concentrated state.

また、本実施形態では、調整機構4及び内筒3は、集中状態においてそれぞれの一部が側面視で互いに重なって配置されている。しかしながら、調整機構4及び内筒3は、集中状態において側面視で互いに重ならず、内筒3の上流側の端部と調整機構4の下流側の端部とが離間して配置されてもよい。 Further, in the present embodiment, a part of the adjusting mechanism 4 and the inner cylinder 3 are arranged so as to overlap each other in a side view in a concentrated state. However, the adjusting mechanism 4 and the inner cylinder 3 do not overlap each other in a side view in a concentrated state, and even if the upstream end of the inner cylinder 3 and the downstream end of the adjusting mechanism 4 are arranged apart from each other. good.

一方、例えば図4(B)に示すように、拡散状態のときはそれぞれの上流側端部411dないし416dが内筒3よりも径方向で外側に位置している。そのため、導入開口4aの大きさは内筒3の開口の大きさよりも大きくなる(導入開口4a2)。これにより、拡散状態のときは、調整機構4は外筒2に流入した空気を内筒3の内側及び外側に導入することができる。 On the other hand, for example, as shown in FIG. 4B, in the diffusion state, the respective upstream end portions 411d to 416d are located outside the inner cylinder 3 in the radial direction. Therefore, the size of the introduction opening 4a is larger than the size of the opening of the inner cylinder 3 (introduction opening 4a2). As a result, in the diffusion state, the adjusting mechanism 4 can introduce the air flowing into the outer cylinder 2 to the inside and the outside of the inner cylinder 3.

さらに、導入開口4aの大きさは、切替羽根411ないし416の回動により導入開口4a1と導入開口4a2との間で連続的に変化する。導入開口4aの大きさが大きくなるにしたがい、外筒2に流入した空気が調整機構4の下流で内筒3の内側を通過する空気の割合が少なくなり、内筒3の外側を通過する空気の割合が多くなるので、より拡散された空気が吹出口装置1から吹き出される。したがって、調整機構4は切替羽根411ないし416の回動により吹出口装置1から吹き出される空気の拡散度合いを調整することができる。 Further, the size of the introduction opening 4a continuously changes between the introduction opening 4a1 and the introduction opening 4a2 due to the rotation of the switching blades 411 to 416. As the size of the introduction opening 4a increases, the proportion of air that has flowed into the outer cylinder 2 passes through the inside of the inner cylinder 3 downstream of the adjusting mechanism 4 decreases, and the air that passes outside the inner cylinder 3 decreases. As the proportion of air increases, more diffused air is blown out from the outlet device 1. Therefore, the adjusting mechanism 4 can adjust the degree of diffusion of the air blown out from the outlet device 1 by the rotation of the switching blades 411 to 416.

2, FIG. 5 (A) and FIG. 5 (B). FIG. 5A is a front view of the outlet device in a concentrated state and the rotating body is removed, and FIG. 5B is a front view of the outlet device in a diffusion state and the rotating body is removed. It is a diagram of the state.

外筒2の下流側には絞り開口部5が設けられている。絞り開口部5は、外筒2の下流側開口2bとともに吹出口装置1の吹出口を構成しており、吹出口装置1から空気が吹き出される際に吹き出し口の開口を絞るためのものである。本実施形態では調整機構4により吹出口装置1から吹き出される空気の拡散及び集中を調整している。それに加えて絞り開口部5が吹き出し口の開口の大きさを調整することにより、より効果的に吹出口装置1から吹き出される空気の拡散及び集中を行うことができる。 A diaphragm opening 5 is provided on the downstream side of the outer cylinder 2. The throttle opening 5 constitutes the outlet of the outlet device 1 together with the downstream opening 2b of the outer cylinder 2, and is for narrowing the opening of the outlet when air is blown out from the outlet device 1. be. In the present embodiment, the adjustment mechanism 4 adjusts the diffusion and concentration of the air blown from the outlet device 1. In addition, by adjusting the size of the opening of the outlet by the throttle opening 5, it is possible to more effectively diffuse and concentrate the air blown out from the outlet device 1.

また、絞り開口部5は、吹出口装置1が車両のインストルメントパネル等に取り付けられた場合に車室内側に露出するため、吹出口装置1の意匠面を兼ねている。本実施形態では、絞り開口部5は下流側開口2bを覆うように設けられ、外筒2に絞り開口部5が外嵌めされている。また、絞り開口部5は、羽根受け部51と、回転体52と、複数の絞り羽根531ないし537とを含む。 Further, since the throttle opening 5 is exposed to the vehicle interior side when the air outlet device 1 is attached to an instrument panel or the like of a vehicle, it also serves as a design surface of the air outlet device 1. In the present embodiment, the throttle opening 5 is provided so as to cover the downstream opening 2b, and the throttle opening 5 is externally fitted to the outer cylinder 2. Further, the diaphragm opening 5 includes a blade receiving portion 51, a rotating body 52, and a plurality of diaphragm blades 531 to 537.

羽根受け部51は、絞り羽根531ないし537を回動可能に支持するための部材であり、外筒2に外嵌めされて設けられている。羽根受け部51は、下流側開口2bを塞ぐように設けられる羽根受け面511と、羽根受け面の外周から上流側に延び、外筒2の側面の下流側端部を覆うように設けられる側面512を有する。羽根受け面511は、その中央に形成される開口511aと、開口511aの外側で周方向に離間して設けられ、絞り羽根531ないし537のそれぞれを回動可能に支持する複数の支持部513aないし513gとを有する。 The blade receiving portion 51 is a member for rotatably supporting the diaphragm blades 531 to 537, and is provided so as to be externally fitted to the outer cylinder 2. The blade receiving portion 51 has a blade receiving surface 511 provided so as to close the downstream opening 2b, and a side surface extending from the outer periphery of the blade receiving surface to the upstream side and covering the downstream end portion of the side surface of the outer cylinder 2. It has 512. The blade receiving surface 511 is provided apart from the opening 511a formed in the center thereof in the circumferential direction on the outside of the opening 511a, and a plurality of support portions 513a to rotatably support each of the diaphragm blades 531 to 537. It has 513 g.

回転体52は、羽根受け部51の周に沿って摺動可能であり、羽根受け部51対して回転することにより絞り羽根531ないし537を回動させるための部材である。回転体52は、羽根受け部51を下流側から覆うように設けられている。また、回転体52は、羽根受け面511と対向する底面521と、底面521の外周から上流側に延び羽根受け部5の側面512の外側に配置される側面522とを有している。 The rotating body 52 is a member that can slide along the circumference of the blade receiving portion 51 and rotates the diaphragm blades 531 to 537 by rotating with respect to the blade receiving portion 51. The rotating body 52 is provided so as to cover the blade receiving portion 51 from the downstream side. Further, the rotating body 52 has a bottom surface 521 facing the blade receiving surface 511, and a side surface 522 extending upstream from the outer periphery of the bottom surface 521 and arranged outside the side surface 512 of the blade receiving portion 5.

回転体52は絞り開口部5の操作部として機能し、ユーザが回転体を操作すると絞り開口部5は回転体52の操作量(回転量)に応じた絞り開口を形成する。回転体52は絞り羽根531ないし537のそれぞれに対応する駆動部523aないし523gを有しており、回転体52の回転に応じて駆動部523aないし523gが絞り羽根531ないし537を回動させる。本実施形態では、駆動部523aないし523gは回転体52の羽根受け部51を向く面から吹出方向上流に向かって突出するピン状の部材である。 The rotating body 52 functions as an operation unit of the diaphragm opening 5, and when the user operates the rotating body, the diaphragm opening 5 forms a diaphragm opening according to the operation amount (rotation amount) of the rotating body 52. The rotating body 52 has a drive unit 523a to 523 g corresponding to each of the diaphragm blades 531 to 537, and the drive unit 523a to 523 g rotates the diaphragm blades 531 to 537 according to the rotation of the rotating body 52. In the present embodiment, the driving portions 523a to 523g are pin-shaped members protruding from the surface of the rotating body 52 facing the blade receiving portion 51 toward the upstream in the blowing direction.

絞り羽根531ないし537は、それぞれ支持部513aないし513gを回動中心として開口511aを出入りするように回動し、回動量に応じた大きさの絞り開口5aを形成する。本実施形態では、絞り羽根531ないし537には、対応する支持部513aないし513gに支持される被支持部531aないし537aがそれぞれ設けられる。また本実施形態では、絞り羽根531ないし537には、対応する駆動部523aないし523gがその内部を貫通する駆動孔531bないし537bがそれぞれ設けられる。回転体52が回転すると、絞り羽根531ないし537はそれぞれ駆動部523aないし523gに付勢されて支持部513aないし513gを回動中心に回動する。これにより、回転体52の回転に応じた絞り羽根531ないし537の位置が定まるので、絞り羽根531ないし537は回転体52の回転に応じた絞り開口5aを形成する。なお、本実施形態では7枚の絞り羽根531ないし537が設けられているが、枚数は7枚の他、6枚以下又は8枚以上であってもよい。 The diaphragm blades 531 to 537 rotate around the support portions 513a to 513g so as to enter and exit the opening 511a, respectively, to form a diaphragm opening 5a having a size corresponding to the amount of rotation. In the present embodiment, the diaphragm blades 531 to 537 are provided with supported portions 531a to 537a supported by the corresponding support portions 513a to 513g, respectively. Further, in the present embodiment, the diaphragm blades 531 to 537 are provided with drive holes 531b to 537b through which the corresponding drive units 523a to 523g penetrate. When the rotating body 52 rotates, the diaphragm blades 531 to 537 are urged by the drive portions 523a to 523g, respectively, and rotate around the support portions 513a to 513g. As a result, the positions of the diaphragm blades 531 to 537 corresponding to the rotation of the rotating body 52 are determined, so that the diaphragm blades 531 to 537 form the diaphragm opening 5a corresponding to the rotation of the rotating body 52. In this embodiment, seven diaphragm blades 531 to 537 are provided, but the number of diaphragm blades may be 6 or less or 8 or more in addition to the 7 diaphragm blades.

集中状態のときは図5(A)に示すように内筒3の開口3aに対応する絞り開口5a(5a1)が形成される。本実施形態では、集中状態のときの絞り開口5aが最小開口5a1である。集中状態ではこの絞り開口5a(最小開口5a1)から吹出口装置1内の空気が吹き出されるので、吹出口装置1はより集中した空気を吹き出すことができる。本実施形態では、最小開口5a1の大きさは内筒3の開口3aの大きさに対応している。これにより、内筒3を通過した空気がより直線的に吹出口装置1の外部に吹き出される。なお、最小開口5a1の大きさは内筒3の開口以上の大きさであってもよく、内筒3の開口以下の大きさであってもよい。さらに、最小開口5a1を全閉状態とする構成も採用可能である。このような構成により、吹出口装置1は集中状態及び拡散状態に加え、車室内に空気を吹き出さない遮断状態も有することができる。 In the concentrated state, as shown in FIG. 5A, a diaphragm opening 5a (5a1) corresponding to the opening 3a of the inner cylinder 3 is formed. In the present embodiment, the aperture opening 5a in the concentrated state is the minimum opening 5a1. In the concentrated state, the air in the outlet device 1 is blown out from the throttle opening 5a (minimum opening 5a1), so that the outlet device 1 can blow out more concentrated air. In the present embodiment, the size of the minimum opening 5a1 corresponds to the size of the opening 3a of the inner cylinder 3. As a result, the air that has passed through the inner cylinder 3 is blown out more linearly to the outside of the outlet device 1. The size of the minimum opening 5a1 may be larger than the opening of the inner cylinder 3 or smaller than the opening of the inner cylinder 3. Further, a configuration in which the minimum opening 5a1 is fully closed can also be adopted. With such a configuration, the outlet device 1 can have a shut-off state in which air is not blown into the vehicle interior in addition to the concentrated state and the diffused state.

一方、拡散状態のときは、例えば図5(B)で示すように羽根受け面511の開口511aよりも大きな絞り開口5a(5a2)が形成される。拡散状態では、絞り開口5aは絞り開口5a1の大きさから絞り開口5a2の大きさまでの範囲で回転体52の回転に応じた大きさとなる。これにより回転体52の回転に応じた拡散度合いの空気を吹き出すことができる。 On the other hand, in the diffused state, for example, as shown in FIG. 5B, a diaphragm opening 5a (5a2) larger than the opening 511a of the blade receiving surface 511 is formed. In the diffused state, the aperture opening 5a has a size corresponding to the rotation of the rotating body 52 in the range from the size of the aperture opening 5a1 to the size of the aperture opening 5a2. As a result, air having a degree of diffusion corresponding to the rotation of the rotating body 52 can be blown out.

図5(A)の状態において回転体52を反時計回りに回転させると、複数の絞り羽根531ないし537はそれぞれ対応する駆動部523aないし523gに付勢され、支持部513aないし513gを回動中心に時計回りに回動し、図5(B)の状態になる。一方、図5(B)の状態において回転体52を時計回りに回転させると、複数の絞り羽根531ないし537はそれぞれ対応する駆動部523aないし523gに付勢され、支持部513aないし513gを回動中心に時計回りに回動し、図5(A)の状態になる。すなわち、本実施形態では、回転体52を時計回りに回転させると絞り開口5aが絞られ、回転体52を反時計回りに回転させると絞り開口5aが拡径する。 When the rotating body 52 is rotated counterclockwise in the state of FIG. 5A, the plurality of diaphragm blades 531 to 537 are urged by the corresponding drive portions 523a to 523g, respectively, and the support portions 513a to 513g are centered on rotation. It rotates clockwise to the state shown in FIG. 5 (B). On the other hand, when the rotating body 52 is rotated clockwise in the state of FIG. 5B, the plurality of diaphragm blades 531 to 537 are urged by the corresponding drive units 523a to 523g, respectively, and rotate the support portions 513a to 513g. It rotates clockwise around the center and becomes the state shown in FIG. 5 (A). That is, in the present embodiment, when the rotating body 52 is rotated clockwise, the aperture opening 5a is narrowed, and when the rotating body 52 is rotated counterclockwise, the aperture opening 5a is expanded.

<内筒移動機構>
再び図2及び図3を参照し、内筒移動機構6について説明する。内筒移動機構6は、回転体52の回転に応じて内筒3を軸方向に移動可能な機構である。上述のように、絞り開口5aは回転体52の回転に応じて変化し、導入開口4aは内筒3の軸方向の移動に応じて変化する。したがって、内筒移動機構6による内筒3の軸方向の移動により、絞り開口部5による絞り開口5aの調整と、調整機構4による導入開口4aの調整とを連動させることができる。
<Inner cylinder movement mechanism>
The inner cylinder moving mechanism 6 will be described with reference to FIGS. 2 and 3 again. The inner cylinder moving mechanism 6 is a mechanism capable of moving the inner cylinder 3 in the axial direction according to the rotation of the rotating body 52. As described above, the throttle opening 5a changes according to the rotation of the rotating body 52, and the introduction opening 4a changes according to the axial movement of the inner cylinder 3. Therefore, by moving the inner cylinder 3 in the axial direction by the inner cylinder moving mechanism 6, the adjustment of the throttle opening 5a by the throttle opening 5 and the adjustment of the introduction opening 4a by the adjusting mechanism 4 can be linked.

内筒移動機構6は、内筒3から径方向に延びる支持アーム611ないし613と、回転体52から上流側へ延出する延出部621ないし623と、支持アーム611ないし613を下流側に付勢する弾性部材631ないし633とを有している。支持アーム611ないし613は内筒3を軸方向に移動可能に支持するアームであり、一端部において内筒3を支持し、他端部611aないし613aが外筒2にの側面に軸方向に移動可能に支持されている。弾性部材631ないし633は例えばバネである。 The inner cylinder moving mechanism 6 has support arms 611 to 613 extending radially from the inner cylinder 3, extending portions 621 to 623 extending upstream from the rotating body 52, and support arms 611 to 613 on the downstream side. It has elastic members 631 to 633 to force. The support arms 611 to 613 are arms that support the inner cylinder 3 so as to be movable in the axial direction. The inner cylinder 3 is supported at one end portion, and the other end portions 611a to 613a move axially to the side surface of the outer cylinder 2. It is supported as much as possible. The elastic members 631 to 633 are, for example, springs.

本実施形態では支持アーム611ないし613の他端部611aないし613aが外筒2の側面よりも外側に位置している。つまり、支持アーム611ないし613は外筒2の側面を貫通して設けられている。例えば外筒2の側面には支持アーム621ないし623が軸方向に通過可能な長穴が設けられている。 In the present embodiment, the other end portions 611a to 613a of the support arms 611 to 613 are located outside the side surface of the outer cylinder 2. That is, the support arms 611 to 613 are provided so as to penetrate the side surface of the outer cylinder 2. For example, the side surface of the outer cylinder 2 is provided with an elongated hole through which the support arms 621 to 623 can pass in the axial direction.

延出部621ないし623は、回転体52の側面522の上流側の縁から延出しており、周方向で支持アーム611ないし613の他端部621aないし623aに対応する位置に設けられている。延出部621ないし623には、外筒2の軸方向に対して傾斜した傾斜部621aないし623aがそれぞれ設けられている。 The extending portions 621 to 623 extend from the upstream edge of the side surface 522 of the rotating body 52, and are provided at positions corresponding to the other end portions 621a to 623a of the support arms 611 to 613 in the circumferential direction. The extending portions 621 to 623 are provided with inclined portions 621a to 623a inclined with respect to the axial direction of the outer cylinder 2, respectively.

他端部611aないし613aは弾性部材631ないし633によって下流側に付勢された状態で傾斜部621aないし623aに当接している。そのため、回転体52が回転すると、他端部611aないし613aは当接している傾斜部621aないし623aの軸方向の位置に伴って軸方向に移動する。例えば、図2の状態から回転体52が反時計回りに回転すると他端部611aないし613aは当接している傾斜部621aないし623aに押されて上流側へ移動する。また例えば、図3の状態から回転体52が時計回りに回転すると他端部611aないし613aは付勢部材631ないし633に付勢されて傾斜部621aないし623aに追従するように下流側に移動する。このように回転体52の回転により支持アーム611ないし613が軸方向に移動すると、支持アーム611ないし613に支持された内筒3も軸方向に移動する。 The other end portions 611a to 613a are in contact with the inclined portions 621a to 623a in a state of being urged to the downstream side by the elastic members 631 to 633. Therefore, when the rotating body 52 rotates, the other end portions 611a to 613a move in the axial direction along with the axial positions of the inclined portions 621a to 623a that are in contact with each other. For example, when the rotating body 52 rotates counterclockwise from the state of FIG. 2, the other end portions 611a to 613a are pushed by the abutting inclined portions 621a to 623a and move to the upstream side. Further, for example, when the rotating body 52 rotates clockwise from the state of FIG. 3, the other end portions 611a to 613a are urged by the urging members 631 to 633 and move downstream so as to follow the inclined portions 621a to 623a. .. When the support arms 611 to 613 move in the axial direction due to the rotation of the rotating body 52 in this way, the inner cylinder 3 supported by the support arms 611 to 613 also moves in the axial direction.

本実施形態では、絞り開口部5、内筒移動機構6、内筒3及び調整機構4の作動により、回転体52が時計回りに回転するほど絞り開口5a及び導入開口4aが小さくなる。吹き出される空気がより集中する。一方、回転体52が反時計回りに回転するほど絞り開口5a及び導入開口4aが大きくなり吹き出される空気がより拡散する。これにより、絞り開口5aを絞る動作と調整機構4による集中状態への切り替えを連動させることができ、また、開口5aを拡げる動作と調整機構4による拡散状態への切り替えを連動させることができる。したがって回転体52の回転に応じた拡散度合いの空気を吹き出すことができる。また、ユーザが視認できる絞り開口5aの大きさと、吹き出される空気の拡散度合いが対応するので、ユーザは直感に合わせて拡散度合いを調整することができる。 In the present embodiment, the throttle opening 5a and the introduction opening 4a become smaller as the rotating body 52 rotates clockwise due to the operation of the throttle opening 5, the inner cylinder moving mechanism 6, the inner cylinder 3, and the adjusting mechanism 4. The blown air is more concentrated. On the other hand, as the rotating body 52 rotates counterclockwise, the throttle opening 5a and the introduction opening 4a become larger, and the blown air is more diffused. Thereby, the operation of closing the aperture opening 5a and the switching to the concentrated state by the adjusting mechanism 4 can be linked, and the operation of expanding the opening 5a and the switching to the diffusion state by the adjusting mechanism 4 can be linked. Therefore, it is possible to blow out air having a degree of diffusion corresponding to the rotation of the rotating body 52. Further, since the size of the aperture opening 5a that can be visually recognized by the user corresponds to the degree of diffusion of the blown air, the user can adjust the degree of diffusion according to his intuition.

このために、絞り開口部5の開く程度と、調整機構4の開く程度とは一致していることが望ましい。すなわち、一方が最大なら他方が最大であり、一方が最小なら他方が最小となる。回転体52の回動範囲は、駆動孔531bないし駆動孔537bの長さによって制限される。その回動範囲内で調整機構4の導入開口4aが最大開口と最小開口との間で変化するように、内筒3を軸方向に移動させる延出部621ないし623の傾斜部621aないし623aの傾きが決定される。 For this reason, it is desirable that the degree of opening of the aperture opening 5 and the degree of opening of the adjusting mechanism 4 match. That is, if one is maximum, the other is maximum, and if one is minimum, the other is minimum. The rotation range of the rotating body 52 is limited by the length of the drive hole 531b to the drive hole 537b. Of the inclined portions 621a to 623a of the extending portions 621 to 623 that move the inner cylinder 3 in the axial direction so that the introduction opening 4a of the adjusting mechanism 4 changes between the maximum opening and the minimum opening within the rotation range. The tilt is determined.

<作動時の空気の流れ>
図6は集中状態における空気の流れを示す模式図であり、図7は拡散状態における空気の流れを示す模式図である。これらの図は、吹出口装置1の断面図を模式的に示したものであり、一部構成を省略している。
<Air flow during operation>
FIG. 6 is a schematic diagram showing the air flow in the concentrated state, and FIG. 7 is a schematic diagram showing the air flow in the diffused state. These figures schematically show a cross-sectional view of the outlet device 1, and some configurations are omitted.

図6で示すように、集中状態では、調整機構4は導入開口4aの大きさが内筒3の開口の大きさに対応するように導入開口4aを調整する。これにより、外筒2の上流側開口2aに流入した空気は矢印で示すように内筒3の内部に誘導される。このため、内筒3を通過した空気が下流側から吹き出される。したがって、吹出口装置1は、内筒3を通過してより集中した空気を演出することができる。また、本実施形態の場合、集中状態では絞り開口5aも内筒3の開口3aに対応した大きさとなるので、吹出口装置1は、より効果的に空気を集中させて吹き出すことができる。 As shown in FIG. 6, in the concentrated state, the adjusting mechanism 4 adjusts the introduction opening 4a so that the size of the introduction opening 4a corresponds to the size of the opening of the inner cylinder 3. As a result, the air flowing into the upstream opening 2a of the outer cylinder 2 is guided to the inside of the inner cylinder 3 as shown by an arrow. Therefore, the air that has passed through the inner cylinder 3 is blown out from the downstream side. Therefore, the air outlet device 1 can pass through the inner cylinder 3 to produce more concentrated air. Further, in the case of the present embodiment, since the throttle opening 5a also has a size corresponding to the opening 3a of the inner cylinder 3 in the concentrated state, the air outlet device 1 can more effectively concentrate and blow out the air.

図7で示すように、拡散状態では、調整機構4は導入開口4aの大きさが内筒3の開口の大きさよりも大きくなるように導入開口4aを調整する。これにより、外筒2の上流側開口2aから流入した空気は矢印で示すように内筒3の内外を通過する。ここで、内筒3の内側を通過する空気は集中状態の時と同様に直線的に吹出口装置1の外部に吹き出される。一方、内筒3の外側を通過する空気は外筒の内面22に形成された螺旋状のリブ21によって螺旋状に流れながら吹出口装置1の外部に吹き出される。螺旋状に吹き出された空気は下流側に進みながら徐々に徐々に軸中心方向に流れ、内筒3から吹き出された空気と衝突するとこれらの空気が拡散する。したがって、吹出口装置1は、内筒3の内外を通過した空気を衝突させることによって吹き出した空気を効果的に拡散させることができる。 As shown in FIG. 7, in the diffusion state, the adjusting mechanism 4 adjusts the introduction opening 4a so that the size of the introduction opening 4a is larger than the size of the opening of the inner cylinder 3. As a result, the air flowing in from the upstream opening 2a of the outer cylinder 2 passes through the inside and outside of the inner cylinder 3 as shown by an arrow. Here, the air passing through the inside of the inner cylinder 3 is linearly blown out to the outside of the outlet device 1 as in the concentrated state. On the other hand, the air passing through the outside of the inner cylinder 3 is blown out to the outside of the outlet device 1 while flowing spirally by the spiral rib 21 formed on the inner surface 22 of the outer cylinder. The air blown out in a spiral shape gradually flows toward the center of the axis while advancing to the downstream side, and when it collides with the air blown out from the inner cylinder 3, these airs are diffused. Therefore, the air outlet device 1 can effectively diffuse the blown air by colliding the air that has passed through the inside and outside of the inner cylinder 3.

本実施形態では、外筒2の内面に螺旋状のリブ21が設けられているが、外筒2を通過した空気が吹出口装置1の外部に吹き出された際に軸中心方向に流れる他の構成を採用してもよい。例えば、外筒2の内面22の下流側開口2bに近接した位置に、軸方向中心に向かって傾斜したリブを周方向にわたって設けてもよい。また、外筒2の下流側開口2b向かって外筒2の径を徐々に小さくしてもよい。 In the present embodiment, the spiral rib 21 is provided on the inner surface of the outer cylinder 2, but other air flowing in the axial center direction when the air passing through the outer cylinder 2 is blown out to the outside of the outlet device 1. The configuration may be adopted. For example, a rib inclined toward the center in the axial direction may be provided over the circumferential direction at a position close to the downstream opening 2b of the inner surface 22 of the outer cylinder 2. Further, the diameter of the outer cylinder 2 may be gradually reduced toward the downstream opening 2b of the outer cylinder 2.
