しかしながら、 従来のエアフィルタは、 空気調和機の使用頻度に応じて室内ュ ニットよりエアフィルタを取り外し、 水洗いもしくは掃除機などで付着した塵埃 を掃除するという定期的なメンテナンスを要し、 特に天井に埋め込まれたタイプ においては非常な手間と労力を必要とする。 また、 定期的にメンテナンスが成さ れなかった場合、 エアフィルタに塵埃が堆積して吸込み空気の通気抵抗が増大し、 空気調和機の性能が低下したり、 消費電力が増大するという課題があった。  However, conventional air filters require regular maintenance, such as removing the air filter from the indoor unit according to the frequency of use of the air conditioner and cleaning the dust attached by washing with water or a vacuum cleaner. The embedded type requires a great deal of effort and effort. In addition, if maintenance is not performed regularly, dust accumulates on the air filter and suction resistance of the intake air increases, which causes problems such as a decrease in the performance of the air conditioner and an increase in power consumption.

発明の開示 Disclosure of the invention
上記目的を達成するため、 本発明は、 筐体内に熱交 と送風機とが収納され た室内ュニットを有する空気調和機であって、 筐体に形成された吸い込み口と前 記熱交^^との間に設けられた回転自在の円盤状のエアフィルタと、 該エアフィ ルタを回転駆動するエアフィルタ駆動手段と、 前記エアフィルタに対向してエア フィルタに付着した塵埃を吸引するための吸い込みノズルが取り付けられた吸引 ユニットとを備えたことを特徴とする。  In order to achieve the above object, the present invention is an air conditioner having an indoor unit in which a heat exchange and a blower are stored in a housing, and the suction port formed in the housing and the heat exchange ^ ^ A rotatable disk-like air filter provided between the air filter, an air filter driving means for rotationally driving the air filter, and a suction nozzle for suctioning dust attached to the air filter against the air filter. And an attached suction unit.
この構成によれば、 円盤状のエアフィルタをエアフィルタ駆動手段で回転する ことにより、 吸い込みノズルを移動させることなくエアフィルタに付着した塵埃 を容易に除去することができる。  According to this configuration, by rotating the disk-shaped air filter by the air filter driving means, dust attached to the air filter can be easily removed without moving the suction nozzle.
また、 吸い込みノスンレにより吸引した塵埃は吸引ュ-ットに設けられた捕集ュ ニットに捕集する力 \ 外部に排出するようにしたので、 室内空気を常にクリーン な状態に維持することができる。  In addition, since the dust sucked by the suction noise is discharged to the outside of the collection unit provided on the suction pad, the room air can be kept clean at all times. .
さらに、 エアフィルタはその外周部に形成されたラックを有するとともに、 ェ アブイルタ駆動手段はラックと嚙合う歯車を有し、 この歯車を回転させることに よりラックを介してエアフィルタを回転させるようにすると、 エアフィルタの回 転機構を簡素でコンパクトに構成することができる。  Furthermore, the air filter has a rack formed on the outer periphery thereof, and the drive means of the air filter has a gear that meshes with the rack, and rotating the gear causes the air filter to rotate through the rack. Then, the rotation mechanism of the air filter can be configured simply and compactly.
また、 吸い込みノズルを吸引ユエットに揺動自在に取り付け、 吸引ユニットの 吸引動作が停止のとき、 吸い込みノズルをエアフィルタの投影面の外に移動する と、 吸い込みノズルが室内ュニットに吸い込まれる空気の抵抗となることはなく 熱交換効率が向上する。  Also, if the suction nozzle is attached to the suction unit so that it can swing freely and the suction operation of the suction unit is stopped, if the suction nozzle is moved out of the projection surface of the air filter, the suction nozzle resists the air drawn into the indoor unit. Heat exchange efficiency is improved.
また、 エアフィルタを挟んで吸い込みノズルの反対側に吸い込みノズルと対向 する遮蔽板を設けると、 吸い込みノズルに吸い込まれる空気の流入経路を制限す ることができ、 集塵効率を向上することができる。 さらに、 遮蔽板と吸い込みノ ズルとを一体的に形成すると、 簡素な構成で遮蔽板を吸い込みノズルとともに揺 動させることができる。 なお、 遮蔽板のエアフィルタに対向する面積を吸い込み ノズルの開口面積と等しいか大きく設定すると、 集塵効率の向上の点で好ましい。 また、 吸い込みノズルの基端部をエアフィルタの略中心に配置し、 吸い込みノ ズルの長さをエアフィルタの半径に略等しく設定するのがよい。 In addition, by providing a shield plate facing the suction nozzle on the opposite side of the suction nozzle with the air filter in between, the inflow path of the air sucked into the suction nozzle can be limited, and the dust collection efficiency can be improved. . Furthermore, if the shielding plate and the suction nozzle are integrally formed, the shielding plate can be shaken with the suction nozzle with a simple configuration. If the area of the shielding plate facing the air filter is set equal to or larger than the opening area of the suction nozzle, it is preferable from the viewpoint of improving the dust collection efficiency. In addition, the proximal end of the suction nozzle may be disposed substantially at the center of the air filter, and the length of the suction nozzle may be set approximately equal to the radius of the air filter.
上述した構成によりエアフィルタを自動的に清掃することができるが、 エアフ ィルタを箧体に着脱自在に取り付けると、 エアフィルタが油汚れした場合には、 エアフィルタを筐体より取り外して清掃することができる。  Although the air filter can be cleaned automatically by the above-mentioned configuration, when the air filter is detachably attached to the housing, if the air filter becomes contaminated with oil, the air filter should be removed from the housing and cleaned. Can.

By operating the suction fan, the dust attached to the air filter 5 is suctioned by the suction nozzle 1 It is sucked by the suction part 1 2 a of 2 and passes through the opening part 1 2 b to reach the collection unit.
吸い込みノズル 1 2は図 2に示すように、 固定軸 1 2 c、 1 2 dを揺動軸とし て自由に揺動することが可能で、 モータ 1 7と固定軸 1 2 cはジョイント 1 8に より互いに接続されている。 吸い込みノズル 1 2が吸引動作を行なう時はモータ 1 7の操作によりエアフィルタ 5の前部に移動し、 吸引動作の必要が無い時はェ ァフィルタ 5と重ならない位置に移動し、 室内ュニットに外部より吸入される空 気の抵抗となるのを防止する。  As shown in Fig. 2, the suction nozzle 12 can freely swing with the fixed shafts 12c and 12d as swing shafts, and the motor 17 and the fixed shaft 12c are joints 1 8 Connected to each other. The suction nozzle 12 moves to the front of the air filter 5 by the operation of the motor 17 when performing suction operation, and moves to a position where it does not overlap with the air filter 5 when there is no need for suction operation. It prevents the resistance of the air being inhaled more.
図 6に示すように、 エアガイダ 4には、 吸い込みノズ /レ 1 2の吸い込み部 1 2 aとほぼ同等の面積を有する遮蔽板 4 bがエアフィルタ 5を挟んで対峙する位置 に設けられている。 この遮蔽板 4 bは吸い込みノズル 1 2に吸い込まれる空気の 流入経路を制限し、 エアフィルタ 5に付着した塵埃を集塵する効率を向上させる ものである。  As shown in FIG. 6, in the air guider 4, a shielding plate 4b having an area substantially equal to that of the suction portion 12a of the suction nozzle 12 is provided at a position opposite to the air filter 5 with the air filter 5 interposed therebetween. . The shielding plate 4 b restricts the inflow path of the air sucked into the suction nozzle 12, and improves the efficiency of collecting dust attached to the air filter 5.
図 8は遮蔽板の別の実施例を示しており、 遮蔽板 1 2 eは吸い込みノズル 1 2 の吸い込み口 1 2 aとほぼ同等の面積を有し、 エアフィルタ 5を挾んで対峙する 位置に、 吸い込みノズル 1 2と一体に形成されている。 前記遮蔽板 4 bと異なり、 本実施例における遮蔽板 1 2 eは吸引動作が停止の状態の時、 吸い込みノズル 1 2とともにエアフィルタ 5の投影面の外に移動してエアフィルタ 5と対向しない ように構成し、 室内ュニットに吸い込まれる空気の抵抗となることを防止する。 エアフィルタ 5はネジ 1 6でエアガイダ 4に回転自在に固定されている。 ネジ 1 6を取り外すことによりエアブイルタ 5も取外しが可能であり吸引装置では取 り除けない油などが付着した場合に取り外して清掃することが出来る。 又、 ネジ 1 6の代替としてエアフィルタ 5の取り付け穴 5 b又はエアガイダ 4の支持軸 4 aに可とう性を持たせ着脱を容易にすることも可能である。 FIG. 8 shows another embodiment of the shielding plate, in which the shielding plate 12 e has an area substantially equal to that of the suction port 12 a of the suction nozzle 12, and is positioned opposite to the air filter 5. , The suction nozzle 12 is integrally formed. Unlike the shielding plate 4b, the shielding plate 12 in this embodiment is a suction nozzle 1 when the suction operation is stopped. By moving together with 2 and outside the projection surface of the air filter 5 so as not to face the air filter 5, the resistance to air drawn into the indoor unit is prevented. The air filter 5 is rotatably fixed to the air guider 4 by a screw 16. The air filter 5 can also be removed by removing the screw 16 so that it can be removed and cleaned if oil that can not be removed by the suction device is attached. Also, as an alternative to the screw 16, it is possible to make the mounting hole 5b of the air filter 5 or the support shaft 4a of the air guider 4 flexible to facilitate the attachment and detachment.
なお、 上記実施の形態において、 吸い込みノズル 1 2により吸引した塵埃を捕 集する捕集ュニットを吸引ュ-ット 1 3に設けたが、 捕集ュニットを設けること なく吸い込みノズル 1 2の開口部 1 2 bに可撓性ホースを接続し、 吸い込みノズ ル 1 2により吸引した塵埃を可撓性ホースを介して外部に排出するようにしても よい。  In the above embodiment, although the collection unit for collecting the dust sucked by the suction nozzle 12 is provided in the suction sheet 13, the opening of the suction nozzle 12 is not provided with the collection unit. A flexible hose may be connected to 12 b and dust sucked by the suction nozzle 12 may be discharged to the outside through the flexible hose.
