背景技術 Background art
従来の空気調和機は、 図 2 8及び図 2 9に示すように、 熱交換器 1 1の前面に、 本体 1 3の内部へ塵埃が侵入することを防ぐためのエアフィルタ 6が設けられて おり、 このエアフィノレタ 6は、 付着した塵埃を手で清掃できるように着脱自在に 構成されている。  As shown in FIGS. 28 and 29, the conventional air conditioner is provided with an air filter 6 at the front of the heat exchanger 11 to prevent dust from entering the inside of the main body 13. The air finleter 6 is configured to be detachable so that the attached dust can be cleaned by hand.
また、 エアフィルタの淸掃を容易にした空気調和機として、 回転ブラシと、 回 転ブラシを回転自在に支持すると共にそれを覆うブラシカバーと、 回転ブラシと 同軸に設けられたピニオンからなるフィルタブラシを備え、 電気掃除機の吸引ノ ズルをブラシカバーに設けた吸引口に接続し、 エアフィルタ上を移動させて、 ェ ァフィルタに堆積した塵埃を回転ブラシでかきとりながら吸引するようにしたも のがある （例えば、 特許文献 1参照) 。  In addition, as an air conditioner that facilitates the cleaning of the air filter, a rotary brush, a brush cover that rotatably supports and covers the rotary brush, and a filter brush composed of a pinion coaxial with the rotary brush The suction nozzle of the vacuum cleaner is connected to the suction port provided on the brush cover, and is moved over the air filter to suck the dust accumulated on the air filter while scraping it with a rotating brush. (For example, see Patent Document 1).
また、 捕集装置と、 清浄装置と、 吸込み機構と、 吸込み機構に繋がる担持ビー ムと、 担持ビームに接続されたホースと、 真空発生器と、 真空発生器の吸引側に 配された分離器などで構成され、 エアフィルタに付着した塵埃を自動的に吸引す るとともに、 その塵埃を分離器で捕集するようにしたものも提案されている (例 えば、 特許文献 2参照) 。  Also, a collecting device, a cleaning device, a suction mechanism, a support beam connected to the suction mechanism, a hose connected to the support beam, a vacuum generator, and a separator disposed on a suction side of the vacuum generator. There has also been proposed a device configured to automatically suck dust attached to an air filter and collect the dust with a separator (for example, see Patent Document 2).
さらに、 ベルト状のエアフィルタを張設した駆動軸及び従動軸と、 駆動軸を駆 動するサーボモータと、 ブラシと、 排気管に配設された塵埃センサー及びファン と、 エアフィルタの連続使用時間を算出する演算処理手段と、 制御手段とを備え、 ベルト状のエアフィルタを回転させながらブラシで塵埃を除去するようにしたも のもある （例えば、 特許文献 3参照） 。  Furthermore, a drive shaft and a driven shaft having a belt-shaped air filter stretched thereon, a servomotor for driving the drive shaft, a brush, a dust sensor and a fan disposed in an exhaust pipe, and a continuous use time of the air filter.

しかしながら、 着脱式のエアフィルタを備えた従来の空気調和機では、 空気調 和機の使用頻度に応じて空気調和機よりエアフィルタを取り外し、 水洗レ、もしく は掃除機などで付着した塵埃を掃除するというメンテナンスを定期的にする必要 があり面倒であった。 そして周期的な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吸込み空気の通気抵抗が増大することから空気調和機の 个生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, with conventional air conditioners equipped with a detachable air filter, the air filter is removed from the air conditioner according to the frequency of use of the air conditioner, and dust adhering to it with a water washing or vacuum cleaner is removed. It was troublesome because it was necessary to periodically perform maintenance such as cleaning. If periodic maintenance is not performed, dust accumulates on the air filter and increases the airflow resistance of the intake air, causing a problem that the individual performance of the air conditioner decreases and power consumption increases. .
また、 特許文献 1に開示されたものでは、 エアフィルタを清掃する都度電気掃 除機を取りだし、 その吸引ノズルをブラシカバーの吸引口に接続し、 エアフィル タ上を移動させなければならず、 非常に手間と時間を要するという問題があった。 また、 特許文献 2に記載されたフィルタ装置の場合、 エアフィルタに付いた塵 埃は自動的に吸引されるが、 その吸引された塵埃は分離器に捕集されるので、 定 期的に分離器に堆積した塵埃を取り除いて処理する必要があり、 面倒であると共 に、 それを怠ると、 エアフィルタに付いた塵埃が除去されなくなり、 吸込み空気 の通気抵抗が増大して空気調和機の性能が低下したり、 消費電力も増大するとい う課題があった。  In addition, in the device disclosed in Patent Document 1, every time the air filter is cleaned, an electric sweeper must be taken out, its suction nozzle connected to the suction port of the brush cover, and moved over the air filter. There is a problem that it takes time and effort. In the case of the filter device described in Patent Document 2, dust attached to the air filter is automatically sucked, but the sucked dust is collected in a separator, so that the dust is periodically separated. It is necessary to remove and accumulate dust accumulated in the air conditioner, and if it is troublesome, if it is not done, the dust attached to the air filter will not be removed, and the ventilation resistance of the intake air will increase and the air conditioner There were issues such as reduced performance and increased power consumption.
さらに、 特許文献 3に開示された空気調和機の場合、 エアフィルタの全幅と略 同じ長さの長尺のブラシが必要となり、 また、 エアフィルタがベルト状になって いるため厚みが増大し、 本体の奥行きサイズが大きくなるという課題があった。 本発明は、 従来技術の有するこのような問題点に鑑みてなされたものであり、 少ない吸引力で効率的に吸塵することができ、 エアフィルタの淸掃、 メンテナン スが極めて容易なエアフィルタの自動清掃機能付き室内ュニットを備えた空気調 和機を«することを目的としている。  Furthermore, in the case of the air conditioner disclosed in Patent Document 3, a long brush that is approximately the same length as the entire width of the air filter is required, and the thickness is increased because the air filter is in a belt shape. There was a problem that the depth size of the main body became large. The present invention has been made in view of the above-mentioned problems of the prior art, and is capable of efficiently absorbing dust with a small suction force, and is very easy to clean and maintain. The purpose is to provide an air conditioner equipped with an indoor unit with an automatic cleaning function.

このフィルタ装置 1は、 フィルタ枠 2と、 フィルタ枠 2に取り付けられたエア フィルタ 6と、 エアフィルタ 6の上流側の面に沿って左右方向 (水平方向：矢印 A) に摺動自在の吸入ノズル 5と、 フィルタ枠 2の一側 (本実施の形態では下 端） の本体 1 3に取り付けられるとともに吸入ノズル 5の一端が気密を保ちなが ら摺動自在に接続された吸い込みダクト 3と、 吸い込みダクト 3に連結され空気 と共に塵埃を吸引、 排気する吸引排気装置 7と、 一端が吸引排気装置 7に連結さ れ、 他端が室外に開口した排気ダクト 8を備えている。  The filter device 1 includes a filter frame 2, an air filter 6 attached to the filter frame 2, and a suction nozzle slidable in the left-right direction (horizontal direction: arrow A) along the upstream surface of the air filter 6. A suction duct 3 attached to the main body 13 on one side (lower end in the present embodiment) of the filter frame 2 and one end of the suction nozzle 5 slidably connected while maintaining airtightness; A suction / exhaust device 7 is connected to the suction duct 3 and sucks and exhausts dust together with air.
吸入ノズル 5は、 図 6 A及び図 6 Bに示すように、 中間部が屈曲した縦長に形 成されて垂直方向に延び、 エアフィルタ 6に面する側にスリット状の吸入口 5 a が設けられている。  As shown in FIGS.6A and 6B, the suction nozzle 5 is formed in a vertically long shape with a bent middle portion, extends vertically, and has a slit-shaped suction port 5a on the side facing the air filter 6. Have been.
吸入ノズル 5を左右に摺動させる駆動手段は、 吸入ノズル 5の吸い込みダクト 3側に連結された駆動用ワイヤ 9と、 駆動用ワイヤ 9を駆動するための駆動モー タ 1 0とで構成されている。  Driving means for sliding the suction nozzle 5 left and right includes a driving wire 9 connected to the suction duct 3 side of the suction nozzle 5 and a driving motor 10 for driving the driving wire 9. I have.
なお、 図 4及び図 5に示されるエアフィルタ 6はフィルタ枠 2に着脱自在に取 り付けられているが、 フィルタ枠 2は本体 1 3の一部であってもよく、 エアフィ ルタ 6を本体 1 3に固定し、 着脱できない構成にすることもできる。 図 7はエアフイノレタ 6を示しており、 凹凸が少なく編成されたネット 6 aを用 いて構成するとともに、 吸入ノズル 5に設けた吸入口 5 aが対面し、 塵埃が付着 する表面側をネット 6 aとネット枠 6 bとの段差が付かないように形成している。 このように構成されたフィルタ装置 1の動作について説明する。 Although the air filter 6 shown in FIGS. 4 and 5 is detachably attached to the filter frame 2, the filter frame 2 may be a part of the main body 13, and the air filter 6 may be attached to the main body 13. It can be fixed to 13 so that it cannot be detached. Fig. 7 shows the air finleter 6, which is constructed using a net 6a knitted with a small amount of unevenness, and a net 6a facing the suction port 5a provided in the suction nozzle 5 and adhering dust.

The dust adhering to the surface is sucked out from the multiple rows of suction ports 5a while being extracted, and the dust passes through the suction duct 3, the suction / exhaust device 7, and is discharged from the exhaust duct 8 to the outside. By providing the brush 5b adjacent to the suction port 5a, dust can be reliably absorbed with a small suction force.
なお、 上記実施の形態において、 空気調和機本体 1 3の運転停止後に吸弓 I排気 装置 7が運転を開始するようにしたが、 空気調和機本体 1 3の運転前あるいは運 転中に吸引排気装置 7を運転するようにしてもよい。  In the above embodiment, the bow suction I exhaust device 7 is started to operate after the operation of the air conditioner main body 13 is stopped, but the suction and exhaust is performed before or during the operation of the air conditioner main body 13. The device 7 may be operated.
また、 上記実施の形態において、 吸引排気装置 7に排気ダクト 8を接続し、 吸 弓 I排気装置 7で吸引した塵埃を空気とともに室外に排出するようにしたが、 排気 ダクト 8は必ずしも設ける必要はない。 この場合、 吸引排気装置 7に集塵ネット を有する着脱自在の集塵ケースを設け、 吸弓 I排気装置 7で吸引した塵埃を集塵ネ ットで捕集する一方、 塵埃とともに吸引された空気を吸引排気装置 7より排出す ればよく、 集塵ネットで捕集した塵埃は集塵ケースを吸引排気装置 7より取り外 すことにより除去することができる。  In the above embodiment, the exhaust duct 8 is connected to the suction and exhaust device 7, and the dust sucked by the suction I exhaust device 7 is discharged to the outside of the room together with the air.However, the exhaust duct 8 is not necessarily provided.
