Description

【0001】
【発明の属する技術分野】
本発明は、フィルターの清掃を自動的に行うようにした空気調和機のフィルター装置に関するものである。
【0002】
【従来の技術】
従来の空気調和機のフィルター装置は、図6に示すように熱交換器10の前面に、空気調和機の本体内部へ塵埃が侵入することを防ぐためのエアフィルター5が設けられており、このエアフィルター5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。
【0003】
一方、エアフィルターの清掃が容易な空気調和機として、エアフィルターの清掃手段として、回転ブラシと、ブラシカバーと、前記回転ブラシに同軸に設けられるピニオンからなるフィルターブラシが構成されているものがある(例えば、特許文献1参照)。
【0004】
また、捕集装置と、清浄装置と、吸込み機構と、前記吸込み機構に繋がる担持ビームと、前記担持ビームに接続されたホースと真空発生器などで構成されているものがある(例えば、特許文献2参照)。
【0005】
また、ベルト状のフィルターを張設した駆動軸及び従動軸と、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、前記フィルターの連続使用時間を算出する演算処理手段と、制御手段とが構成されている(例えば、特許文献3参照)。

【特許文献3】
特開平6−74521号公報(第2頁、第1図)
【0007】
【発明が解決しようとする課題】
しかしながら、上記従来のフィルターの構成では、空気調和機の使用頻度に応じて空気調和機より取り外し、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周期的なメンテナンスを要する。また、周期的なメンテナンスが成されなかった場合、エアフィルターに塵埃が堆積し吸込み空気の通気抵抗が増大するため空気調和機の性能が低下、消費電力が増大するという課題があった。
【0008】
また、動作手段に制約があったり、集塵後の塵埃処理の手間が発生するなどして確実な手段ではなかった。また、本体サイズが拡大化するなどの課題を有した。
【0009】
【課題を解決するための手段】
上記課題を解決するために、本発明のフィルター装置は、フィルター枠と、エアフィルターと、移動可能な吸入ノズルを設け、この吸入ノズルに吸い込みダクトを設け、さらに前記吸い込みダクトに連結する吸引排気装置と排気ダクトを具備した空気調和機において、前記吸入ノズルに複数個の可変吸入口を千鳥に設けたものである。
【0010】
上記構成により、エアフィルターの清掃を自動的に行うことが可能になり、空気調和機の性能維持、及び消費電力の増大防止を図ることができる。また、ノズルの手前から奥まで均一にムラなく吸塵することができる。
【0011】
【発明の実施の形態】
以下本発明の実施の形態について、図面を参照して説明する。
【0012】
図1は本発明の実施の形態におけるフィルター装置の斜視図、図2は本発明の実施の形態におけるフィルター装置の吸入ノズルの外観図、図3は発明の実施の形態における室内機の正面図、図4、図5は本発明の実施の形態における空気調和機の断面図である。
【0013】
空気調和機本体11の内部には、熱交換器10とファン(図示せず)が配設されており、本体11の前面から上面に渡り形成される複数の吸込口(図示せず)からは、ファンの動作により空気が吸い込まれ、これらの空気中に漂う塵埃は、前記吸込口と熱交換器10との間に設けたフィルター装置1で取り除かれる。
【0014】
このフィルター装置1は、フィルター枠2と、エアフィルター5と、移動可能な吸入ノズル4を設け、この吸入ノズル4に吸い込みダクト3を設け、さらに前記吸い込みダクト3に連結する吸引排気装置6と排気ダクト7を具備した空気調和機において、前記吸入ノズル4に複数個の可変吸入口4aを千鳥に設け、さらに前記複数個の可変吸入口4aの長さ寸法Bは、上方向及び奥方向に行くにしたがって大きくなるように設定している。さらに前記吸入口4aに隣接するブラシ4bを設けたものである。
【0015】
このように構成されたフィルター装置1の動作について説明する。空気調和機本体11の運転停止後に、吸引排気装置6が運転開始し、吸い込みダクト3に設置された吸入ノズル4の吸入口4aから空気を吸い込み始める。そして、エアフィルター5の片側端に位置していた吸入ノズル4が、駆動モータ9に連結された駆動用ワイヤー8によって矢印A方向に移動し、吸入ノズル4のブラシ4bがエアフィルター5の表面についた埃を掻き出しながら、吸入ノズル4の複数個の可変吸入口4aから吸い取り、塵埃は吸い込みダクト3、吸引排気装置6を通り、排気ダクト7から室外へ吐き出される。
【0016】
ここで、吸入ノズル4がエアフィルター5の表面を全面清掃し、対向する片側端まで移動したときに駆動モータ9を逆回転させれば、吸入ノズル4は初期の位置に戻る方向に移動して、もう一度エアフィルター5の表面を清掃することが可能となる。
【0017】
そして、この実施例によれば、吸入ノズル4の手前から奥まで均一にムラなく吸塵することができる。
【0018】
【発明の効果】
上記から明らかなように、本発明は、フィルター装置にフィルター枠と、エアフィルターと、移動可能な吸入ノズルを設け、この吸入ノズルに吸い込みダクトを設け、さらに前記吸い込みダクトに連結する吸引排気装置と排気ダクトを具備した空気調和機において、前記吸入ノズルに複数個の可変吸入口を千鳥に設け、さらに前記吸入口に隣接するブラシを設けたものである。この構成によれば、ノズルの手前から奥まで均一にムラなく吸塵することができるという効果を奏する。

[0007]
[Problems to be solved by the invention]
However, the above-described conventional filter configuration requires periodic maintenance such as removing the air conditioner from the air conditioner in accordance with the frequency of use of the air conditioner, and washing the attached dust with water or a vacuum cleaner. In addition, when the periodic maintenance is not performed, dust accumulates on the air filter, and the ventilation resistance of the intake air increases, so that the performance of the air conditioner decreases and the power consumption increases.
[0008]
In addition, there are restrictions on the operation means, and the time and effort for dust treatment after dust collection are increased, so that the method is not reliable. In addition, there is a problem that the body size is enlarged.
[0009]

According to the above configuration, it is possible to automatically clean the air filter, thereby maintaining the performance of the air conditioner and preventing an increase in power consumption. Further, dust can be uniformly absorbed from the front to the back of the nozzle without unevenness.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
1 is a perspective view of a filter device according to an embodiment of the present invention, FIG. 2 is an external view of a suction nozzle of the filter device according to an embodiment of the present invention, FIG. 3 is a front view of an indoor unit according to the embodiment of the present invention, 4 and 5 are cross-sectional views of the air conditioner according to the embodiment of the present invention.
[0013]
Inside the air conditioner main body 11, a heat exchanger 10 and a fan (not shown) are disposed, and a plurality of suction ports (not shown) formed from the front surface to the upper surface of the main body 11 are provided. The air is sucked in by the operation of the fan, and the dust floating in the air is removed by the filter device 1 provided between the suction port and the heat exchanger 10.
[0014]

In the air conditioner provided with the duct 7, a plurality of variable suction ports 4a are provided in a staggered manner in the suction nozzle 4, and the length dimension B of the plurality of variable suction ports 4a goes upward and backward. Is set so as to increase in accordance with. Further, a brush 4b is provided adjacent to the suction port 4a.
[0015]
The operation of the filter device 1 configured as described above will be described. After the operation of the air conditioner main body 11 is stopped, the suction and exhaust device 6 starts operating, and starts sucking air from the suction port 4 a of the suction nozzle 4 installed in the suction duct 3. Then, the suction nozzle 4 located at one end of the air filter 5 is moved in the direction of arrow A by the driving wire 8 connected to the drive motor 9, and the brush 4 b of the suction nozzle 4 is attached to the surface of the air filter 5. The dust is sucked out from the plurality of variable suction ports 4a of the suction nozzle 4 while being scraped out, and the dust passes through the suction duct 3 and the suction / exhaust device 6, and is discharged from the exhaust duct 7 to the outside of the room.
[0016]
Here, if the drive motor 9 is rotated reversely when the suction nozzle 4 cleans the entire surface of the air filter 5 and moves to the opposite one end, the suction nozzle 4 moves in the direction to return to the initial position. Thus, the surface of the air filter 5 can be cleaned again.
[0017]
According to this embodiment, dust can be uniformly and uniformly absorbed from the front to the back of the suction nozzle 4.
[0018]
