Description

この発明は、風向き変更用の水平フラップを駆動するモータを備えた空気調和機に関するものである。   The present invention relates to an air conditioner including a motor that drives a horizontal flap for changing the wind direction.

空気調和機の室内ユニット内の電気的制御を行う電気部品は、予め電装品箱に組み付けておいてから、該室内ユニットに組み付けるのが、手数を要さず、組立作業を効率的に行える。吸込ルーバーを回転駆動させるモータを、予め電装品箱に組み付けたものとして、例えば下記に示す特許文献１を挙げることができる。   It is not necessary to assemble the electrical parts for performing electrical control in the indoor unit of the air conditioner in advance in the electrical component box and then in the indoor unit, so that assembly work can be performed efficiently. For example, Patent Document 1 shown below can be cited as an example in which a motor for rotating the suction louver is assembled in advance in the electrical component box.

この特許文献１では、ルーバー駆動部が、駆動軸を備えた駆動モータと、同駆動モータの駆動軸に取り付けられてそのトルクを連結ロッドの前後動に変換し、前記駆動モータのトルクを補助するバネを設けたアームとで構成されている。そして、電装品箱にネジ孔を設けるとともに、前記駆動モータに備えた脚部の挿通孔を挿通したねじを前記ネジ孔に螺着して、前記駆動モータを電装品箱に固定したものである。これにより、部品点数を削減するとともに、吸込ルーバーで上面の吸込口を正確に回動できるようにしている。   In this Patent Document 1, a louver drive unit is attached to a drive motor having a drive shaft and a drive shaft of the drive motor, and converts the torque into the longitudinal movement of a connecting rod to assist the torque of the drive motor. And an arm provided with a spring. The electrical component box is provided with a screw hole, and a screw inserted through a leg insertion hole provided in the drive motor is screwed into the screw hole to fix the drive motor to the electrical component box. . As a result, the number of parts is reduced and the suction port on the upper surface can be accurately rotated by the suction louver.

ところで、空気の吹出口の開口部には、風向き変更用の水平フラップが回動自在に設けられていて、この水平フラップの一方にステッピングモータが配設されている。このステッピングモータにより水平フラップが回動制御されるようになっている。   By the way, a horizontal flap for changing the wind direction is rotatably provided at the opening of the air outlet, and a stepping motor is disposed on one of the horizontal flaps. The horizontal flap is controlled to rotate by this stepping motor.

現在のところ、ステッピングモータは電装品箱には固定されずモジュール化されていない。それは、ステッピングモータは強固に固定されないと羽根の位置がずれて不具合を発生させることになるからである。そのため、ステッピングモータを電装品箱とは別個に室内ユニット内に組み付けていて、組立ラインの工数増加の要因となっていた。
特開２００２−３１３６５号公報 At present, the stepping motor is not fixed to the electrical component box and is not modularized. This is because if the stepping motor is not firmly fixed, the position of the blades will shift and cause problems. Therefore, the stepping motor is assembled in the indoor unit separately from the electrical component box, which causes an increase in the number of assembly lines.
JP 2002-31365 A

そこで上記特許文献１に開示された技術を利用して、ステッピングモータを電装品箱に予め組み付けておくことを着想した。しかしながら、上記特許文献１では、モータの取り付け部分に剛性が得にくく、また、連結ロッドとアームとの取り付け精度が得にくいという問題を有しており、これをステッピングモータの組み付けにそのまま適用することは不可能である。   Accordingly, the inventors have conceived that the stepping motor is assembled in advance in the electrical component box using the technique disclosed in Patent Document 1 above. However, in the above-mentioned Patent Document 1, there is a problem that it is difficult to obtain rigidity in the motor mounting portion and it is difficult to obtain mounting accuracy between the connecting rod and the arm, and this is applied as it is to the assembly of the stepping motor. Is impossible.

（１）水平フラップを回動制御するモータを電装品箱側に配設してモジュール化ないしユニット化し、組立性を向上させること。
（２）モータの固定部分の強化を図ること。
（３）モータを本体側に対して位置決めができて、モータの取り付け精度を上げ、同時に剛性を持たせることで、水平フラップの回動制御に支障を与えないようにすること。 (1) A motor for rotating the horizontal flap is arranged on the electrical component box side to be modularized or unitized to improve assemblability.
(2) To strengthen the fixed part of the motor.
(3) The motor can be positioned with respect to the main body side, the mounting accuracy of the motor is increased, and at the same time, rigidity is given so as not to hinder the rotation control of the horizontal flap.

そこで、請求項１に記載の空気調和機では、空気を吸い込む吸込口４と、この吸込口４から吸い込んだ空気を熱交換器８で熱交換し、この熱交換した空気をクロスフローファンの作用にて外部へ吹き出す吹出口６とを有する本体ケーシング３と、前記本体ケーシング３に配設されると共に、電気的制御を行なう電気部品を予め組み付けた電装品箱１１と、前記本体ケーシング３の吹出口６の開口部に配設されて、風向きを変更させる水平フラップ７と、前記水平フラップ７を駆動するモータ２５とを備えている空気調和機において、前記モータ２５を前記電装品箱１１に予め組み付けておき、該電装品箱１１をモジュール化していることを特徴としている。また、請求項４に記載の空気調和機では、運転状態を表示する運転表示ランプ箱１２を、さらに前記電装品箱１１に予め組み付けておくことを特徴としている。   Therefore, in the air conditioner according to the first aspect, the suction port 4 for sucking air and the air sucked from the suction port 4 are heat-exchanged by the heat exchanger 8, and the heat-exchanged air is operated by the cross flow fan.

The electrical component box 11 is modularized by being assembled. The air conditioner according to claim 4 is characterized in that an operation display lamp box 12 for displaying an operation state is further assembled in advance to the electrical component box 11.

請求項２に記載の空気調和機では、前記モータ２５の両側の近傍に前記電装品箱１１と本体ケーシング３との固定手段を設けていることを特徴としている。   The air conditioner according to claim 2 is characterized in that fixing means for the electrical component box 11 and the main body casing 3 is provided in the vicinity of both sides of the motor 25.

請求項３に記載の空気調和機では、前記電装品箱１１と本体ケーシング３の底フレーム５との固定手段が、略Ｕ字状で一方に開口した一対の固定片５０、５１と、前記固定片５０、５１にそれぞれ圧入嵌合する一対の凸部５２、５３とより成ることを特徴としている。   In the air conditioner according to claim 3, the fixing means between the electrical component box 11 and the bottom frame 5 of the main body casing 3 is a pair of fixing pieces 50 and 51 that are substantially U-shaped and open to one side, and the fixing It consists of a pair of convex parts 52 and 53 press-fitted to the pieces 50 and 51, respectively.

本発明の請求項１に記載の空気調和機によれば、前記モータ２５を前記電装品箱１１に予め組み付けておき、該電装品箱１１をモジュール化しているので、このモジュール化した電装品箱１１を単に本体ケーシング３側に取り付けるだけとなり、そのため、室内ユニット１の組み立ての工数を削減でき、組立性を一層向上させることができる。また、請求項４に記載の空気調和機では、運転表示ランプ箱１２を前記電装品箱１１に予め組み付けておくので、組立性をより一層向上させることができる。   According to the air conditioner of the first aspect of the present invention, since the motor 25 is assembled in advance to the electrical component box 11 and the electrical component box 11 is modularized, this modularized electrical component box 11 is simply attached to the main body casing 3 side. Therefore, the number of steps for assembling the indoor unit 1 can be reduced, and the assemblability can be further improved.
