- control unit 40 rotates the vertical wind direction adjusting blade 31 to a position where the inner side surface 31b of the vertical wind direction adjusting blade 31 is substantially horizontal. As a result, conditioned air is blown out substantially horizontally from the blowout port 15.
- control unit 40 swings the blade piece 201 of the vertical wind direction adjusting blade 20 left and right to blow out the blown air alternately left and right.
- the controller 40 alternately rotates the rotating shaft 51a of the motor 51 clockwise and counterclockwise in order to reciprocate the connecting rod 203 along the longitudinal direction of the air outlet 15.
- the connecting rod 203 does not draw a simple reciprocating motion, but the tip of the arm portion 551 reciprocates while drawing an arc locus as shown in FIG. This is because when the blade piece 201 of the vertical wind direction adjusting blade 20 swings left and right, the connecting rod 203 moves so as to be pushed forward of the air outlet 15, so that the connecting rod 203 itself also draws an arc locus. In order not to disturb the movement.
- the arm portion 551 draws a curved track (arc track).
- the swinging motion of the rack can be taken out directly from the rack and pinion.
- the deflection width in the direction intersecting the longitudinal direction of the arm portion 551 is the ratio of the displacement h in the direction intersecting the longitudinal direction at the tip of the arm portion 551 to the moving distance L in the longitudinal direction of the arm portion 551.
- (h / L) it is set within the range of 0.15 to 0.25, and the radius of the circular arc drawn by the tip of the arm portion 551 becomes 100 mm or less.
- the cause of the swinging movement of the rack 55 from the rack and pinion mechanism of the drive unit 70 is that the clearance between the arm portion 551 of the rack 55 and the cylindrical portion 571 of the guide 57 that guides the arm portion 551 is normally set. It has been expanded to the extent that it is not set.
- the rack 55 is used by moving the clearance with a member that guides the rack 55 to the extent that there is no hindrance to the movement.
- the tip of the portion 551 can be rotated about the vicinity of the meshing point between the rack 55 and the pinion 53, and the tip can swing according to the clearance when the rack 55 reciprocates.
- the clearance between the arm portion 551 and the cylinder portion 571 can be changed by adjusting the height of the protrusion 553 of the rack 55. That is, the clearance between the protrusion 553 and the inner surface of the cylindrical portion 571 has a swing width in a direction intersecting the longitudinal direction of the arm portion 551. Therefore, a necessary swing width can be obtained by adjusting this clearance.
- the swing motion can be taken out directly from the rack and pinion mechanism, so that the conventional linear motion of the rack is converted into the swing motion. Members can be omitted.
- the swing motion can be extracted directly from the rack 55 and the pinion 53 by drawing the curved trajectory on the rack.
- a member for converting the linear motion of the rack into the swing motion can be omitted.
- the swing amount of the blade piece 201 of the vertical wind direction adjusting blade 20 can be adjusted by the rotation amount of the pinion 53, the distance [from the motor shaft to the connection point between the first link and the second link] as in the prior art.
- the torque of the motor can be made smaller than the configuration in which the swing amount is adjusted.

上下風向調整羽根31は、吹出口15を塞ぐことができる程度の面積を有している。上下風向調整羽根31が吹出口15を閉じた状態において、その外側面31aは前面パネル11bの曲面の延長上にあるような外側に凸のなだらかな円弧曲面に仕上げられている。また、上下風向調整羽根31の内側面31b(図2A及び図2B参照)も、外面にほぼ平行な円弧曲面を成している。
図3は、羽根片201及びその周辺の斜視図である。図3において、垂直風向調整羽根20は、複数の羽根片201と、複数の羽根片201を連結する連結棒203を有している。また、垂直風向調整羽根20は、吹出流路18において、上下風向調整羽根31よりも室内ファン14近傍に配置されている。
図4Aは、本発明の一実施形態に係る駆動ユニット70の第1状態における当該駆動ユニット70の断面図である。また、図4Bは、第2状態における駆動ユニット70の断面図である。さらに、図4Cは、第3状態における駆動ユニット70の断面図である。
モータ51は、ステッピングモータである。モータ51は、入力されるパルス数に応じた回転量を出力する回転軸51aを有している。
ピニオン53は、モータ51の回転軸51aに固定される小型の歯車である。ピニオン53は、モータ51の回転軸51aの回転方向と同じ方向に、回転軸51aの回転量と同じ回転量を出力する。
ラック55は、ラック部552とアーム部551とを有している。ラック部552は、ピニオン53と噛み合う。また、ラック部552は、ピニオン53との噛み合い部分を挟んでピニオン53と反対側の領域に案内溝557が設けられている。案内溝557において、長手方向の2つの対向する端面の間隔は、ラック55の移動距離よりも大きい。
ガイド57は、ラック55が貫通する筒部571から成り、アーム部551が湾曲軌道を描きながら移動できるようにラック55を案内する。
ギアボックス61は、ラック55とピニオン53との噛み合い部分を収容する。ガイド57は、ギアボックス61内部と連通しラック55が貫通する筒部571を有している。
駆動ユニット70が搭載されている空調室内機10の運転、例えば冷房運転が開始されると、図2Aに示すように、上下風向調整羽根31の回動軸311が反時計方向に回動することによって、上下風向調整羽根31の上端が吹出口15の上端側から遠ざかるように動作して吹出口15を開ける。
(4-1)
駆動ユニット70では、回転運動を往復直線運動に変換するラック&ピニオン機構において、ラックに湾曲軌道を描かせることによって、ラック55とピニオン53とから直に揺動運動を取り出せるので、従来のようなラックの直線運動を揺動運動に変換する部材を省くことができる。また、ピニオン53の回転量で垂直風向調整羽根20の羽根片201のスイング量を調節できるので、従来のような[モータ軸から第1のリンクと第2のリンクとの連結点まで]の距離でスイング量を調節する構成よりもモータのトルクを小さくすることができる。
ガイド57が、ラック55のアーム部551の長手方向と交差する方向の振れ幅を所定範囲まで許容することによって、アーム部551が湾曲軌道(円弧軌道)を描かくので、ラック55とピニオン53とから直にラック55の揺動運動を取り出すことができる。したがって、従来のようなリンク構造よりも部品点数を少なくすることができる。
突起553と筒部571内面とのクリアランスが、ラック55のアーム部551の長手方向と交差する方向の振れ幅をとなるので、このクリアランスを調整することによって必要な振れ幅を得ることができる。
鍔555が存在することによって筒部571への冷風の進入が阻害されるので、筒部571の内側が結露するような事態は防止される。
モータ51が万一オーバーランしてもラック55の案内溝557にギアボックス61側のリブ611が入り込んでいるので、リブ611と案内溝557の端部とが当接してラック55の抜け落ちは防止される。
