Description

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。   The present invention relates to a filter device for an air conditioner that automatically cleans a filter.

従来、図４および図５に示すように、空気調和機のフィルター装置は、空気調和機の本体１０１内部へ埃が侵入することを防ぐために、熱交換器１０２の前面にエアフィルター１０３を設けており、このエアフィルター１０３に付着した塵埃を手で清掃できるように、エアフィルター１０３が着脱自在に構成されている。   Conventionally, as shown in FIGS. 4 and 5, the air conditioner filter device is provided with an air filter 103 on the front surface of the heat exchanger 102 in order to prevent dust from entering the inside of the main body 101 of the air conditioner. The air filter 103 is detachable so that dust adhering to the air filter 103 can be manually cleaned.

しかし、このようなエアフィルターを着脱自在に構成した空気調和機では、空気調和機の使用頻度に応じた周期で、エアフィルターを空気調和機の室内機から取り外し、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メンテナンスを要し、多くの手間や時間が掛かってしまう課題があった。またメンテナンスが必要となるだけではなく、メンテナンスが行われるまでに、エアフィルターが徐々に目詰まりしていき、その結果、熱交換器を通過する風量が低下するため、空調能力が低下し消費電力の増大につながる。   However, in an air conditioner with such an air filter detachable, remove the air filter from the indoor unit of the air conditioner at a cycle according to the frequency of use of the air conditioner, and attach it with water or a vacuum cleaner. This requires maintenance to clean the dust, and has a lot of trouble and time. In addition to the need for maintenance, the air filter is gradually clogged by the time maintenance is performed, and as a result, the amount of air passing through the heat exchanger decreases, resulting in a reduction in air conditioning capacity and power consumption. Leads to an increase in

それに対して、エアフィルターの定期的な清掃の煩わしさを解消する目的で、エアフィルターを自動的に清掃するフィルター装置がある（例えば、特許文献１参照）。以下に、従来のエアフィルターを自動的に清掃する空気調和機のフィルター装置の構成と作用を図６および図７を用いて説明する。図６は従来の空気調和機のフィルター装置の斜視図、図７は従来の空気調和機のフィルター装置における吸入ノズル外観図である。   On the other hand, there is a filter device that automatically cleans the air filter for the purpose of eliminating the troublesome periodic cleaning of the air filter (see, for example, Patent Document 1). Below, the structure and effect | action of the filter apparatus of the air conditioner which cleans the conventional air filter automatically are demonstrated using FIG. 6 and FIG. FIG. 6 is a perspective view of a filter device of a conventional air conditioner, and FIG. 7 is an external view of a suction nozzle in the filter device of the conventional air conditioner.

図６において、従来の空気調和機のフィルター装置２００は、フィルター枠２０１ａとフィルター網２０１ｂで構成されるエアフィルター２０２と、移動可能な吸入ノズル２０３と、吸入ノズル２０３に吸い込みダクト２０４を設け、さらに吸い込みダクト２０４に連結する吸引排気装置２０５と排気ダクト２０６から構成したものである。吸入ノズル２０３は図７に示すように、吸入ノズルの移動方向に対し２本並べた形態で配設し、それぞれに第一吸入口２０３ａ、第二吸入口２０３ｂを設けている。第一吸入口２０３ａはエアフィルター２０２の前面部に相対する位置に、第二吸入口２０３ｂはエアフィルター２０２の上面部に相対する位置に開口している。空気調和機本体の内部には、熱交換器とファンが配設されており、本体の前面から上面にわたり形成される複数の吸い込み口から、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、前記吸い込み口と熱交換器との間に設けた前記フィルター装置で取り除かれる。   In FIG. 6, the filter device 200 of the conventional air conditioner includes an air filter 202 composed of a filter frame 201a and a filter net 201b, a movable suction nozzle 203, and a suction duct 204 in the suction nozzle 203. A suction exhaust device 205 connected to a suction duct 204 and an exhaust duct 206 are configured. As shown in FIG. 7, the two suction nozzles 203 are arranged in the moving direction of the suction nozzle, and are provided with a first suction port 203a and a second suction port 203b, respectively. The first suction port 203 a is opened at a position facing the front surface of the air filter 202, and the second suction port 203 b is opened at a position facing the upper surface of the air filter 202. Inside the air conditioner main body, a heat exchanger and a fan are arranged, and air is sucked in by the operation of the fan from a plurality of suction ports formed from the front surface to the upper surface of the main body. Drifting dust is removed by the filter device provided between the suction port and the heat exchanger.

このように構成されたフィルター装置２００の動作について説明する。空気調和機の運転停止後に、吸引排気装置２０５が運転開始し、吸い込みダクト２０４に設置された吸入ノズル２０３に設けた第一吸入口２０３ａおよび第二吸入口２０３ｂから空気を吸い込み始める。そして、エアフィルター装置の片側端に位置していた吸入ノズル２０３が、駆動モータ２０７に連結された駆動用ワイヤー２０８によって、図６に示すようにＡの矢印方向に移動し、エアフィルター２０２の表面に付着した塵埃を吸入ノズル２０３に設けた第一吸入口２０３ａおよび第二吸入口２０３ｂから吸い取り、塵埃は吸い込みダクト２０４、吸引排気装置２０５の順に通り、排気ダクト２０６から室外へ吐き出される。   The operation of the filter device 200 configured as described above will be described. After the operation of the air conditioner is stopped, the suction / exhaust device 205 starts to operate and starts to suck air from the first suction port 203a and the second suction port 203b provided in the suction nozzle 203 installed in the suction duct 204. Then, the suction nozzle 203 located at one end of the air filter device is moved in the direction of the arrow A as shown in FIG. 6 by the drive wire 208 connected to the drive motor 207, and the surface of the air filter 202 is moved. The dust adhering to the suction nozzle 203 is sucked from the first suction port 203a and the second suction port 203b provided in the suction nozzle 203, and the dust passes through the suction duct 204 and the suction exhaust device 205 in this order, and is discharged from the exhaust duct 206 to the outside.

ここで、吸入ノズル２０３がエアフィルター２０２の表面を前面清掃し、対向する片側端まで移動したときに駆動モータ２０７を逆回転させれば、吸入ノズル２０３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２０２の表面を清掃することが可能で
ある。
特開２００４−２６３９８４号公報 Here, when the suction nozzle 203 cleans the front surface of the air filter 202 and moves to the opposite one end, if the drive motor 207 is reversely rotated, the suction nozzle 203 moves in a direction to return to the initial position. It is possible to clean the surface of the air filter 202 once more.

しかしながら前記従来技術では、騒音や電源容量不足の面から、吸引排気装置内に設けた吸引を行うためのファンの回転数を上げることができず、小出力でも清掃時の吸引力を確保するためには吸引ノズルや吸引ダクトや排気ダクトの通風抵抗値を小さくしなければならなかった。通風抵抗値は、理論的に風速の２乗に比例し、通風量に対して大きな通風路断面積を取り、風速を落とすことで通風抵抗値を小さくすることができる。つまり通風抵抗値を小さくするためには、吸引ノズルや吸引ダクト、排気ダクトの通風路の断面積を大きくして風速を遅くしなければならないが、風速が遅いと、吸引清掃で吸い込んだ塵埃を排出するだけの風速が確保できず、排気ダクト、吸引排気装置の内部に堆積するという課題があった。   However, in the above prior art, the rotational speed of the fan for performing the suction provided in the suction / exhaust device cannot be increased due to noise and the lack of power supply capacity, so that the suction force at the time of cleaning can be secured even with a small output. However, the ventilation resistance value of the suction nozzle, suction duct and exhaust duct had to be reduced. The ventilation resistance value is theoretically proportional to the square of the wind speed, and the ventilation resistance value can be reduced by taking a large cross-sectional area of the ventilation path with respect to the ventilation volume and reducing the wind speed. In other words, in order to reduce the ventilation resistance value, it is necessary to increase the cross-sectional area of the ventilation path of the suction nozzle, suction duct, and exhaust duct to slow down the wind speed, but if the wind speed is slow, dust sucked in by suction cleaning will be removed. There was a problem that it was not possible to secure a wind speed sufficient for discharging, and it was deposited inside the exhaust duct and the suction exhaust apparatus.

本発明は、前記課題の排気ダクトおよび吸引排気装置内の塵埃堆積を解決するもので、高性能なエアフィルター清掃能力を有し、メンテナンスの手間も大幅に低減する空気調和機のフィルター装置を提供することを目的とする。   The present invention provides a filter device for an air conditioner that solves the above-mentioned problems of dust accumulation in the exhaust duct and the suction exhaust device, has a high-performance air filter cleaning capability, and greatly reduces maintenance labor. The purpose is to do.

前記従来の課題を解決するために、本発明の空気調和機のフィルター装置は、エアフィルターと、吸引ノズルと、吸引ノズルに連通された吸引排気装置を具備し、前記吸引排気装置には開口部と開閉板と開閉駆動手段を設け、前記開閉板にシール材を貼付したフィルター装置において、前記シール材の表面を埃が付着しにくい材質にしたものである。
これによって、シール材や開閉板が閉じた時に当接する開口部の近傍に塵埃が付着しても、開閉板にシール材を貼付しているため、シール材が柔軟に変形し確実に閉じることができる。またシール材の表面を埃が付着しにくくしてあるので、シール材への塵埃堆積を防止することができる。 In order to solve the above-described conventional problems, a filter device of an air conditioner of the present invention includes an air filter, a suction nozzle, and a suction exhaust device communicated with the suction nozzle, and the suction exhaust device has an opening portion. In the filter device in which an opening / closing plate and an opening / closing driving means are provided and a sealing material is attached to the opening / closing plate, the surface of the sealing material is made of a material that is difficult to adhere dust.
As a result, even if dust adheres to the vicinity of the opening that abuts when the sealing material or the opening / closing plate is closed, the sealing material is affixed to the opening / closing plate, so that the sealing material can be flexibly deformed and reliably closed. it can. In addition, since dust is less likely to adhere to the surface of the sealing material, dust accumulation on the sealing material can be prevented.

また、本発明の空気調和機のフィルター装置は、吸引清掃動作後に、吸引排気装置に設けた開閉板の開動作を行うものである。
これによって、吸引排気装置に設けた開口部を開くことで、吸引排気装置より下流の流量を増やし、吸引排気装置や排気ダクトの内部に堆積した塵埃を排出することができる。 Moreover, the filter apparatus of the air conditioner of the present invention performs an opening operation of the opening / closing plate provided in the suction exhaust apparatus after the suction cleaning operation.
Thus, by opening the opening provided in the suction exhaust apparatus, the flow rate downstream from the suction exhaust apparatus can be increased, and dust accumulated in the suction exhaust apparatus and the exhaust duct can be discharged.

また、本発明の空気調和機のフィルター装置は、開閉板によって塵埃清掃機能と塵埃排出機能を切り替えるものである。
これによって、吸引排気装置が塵埃清掃装置と塵埃排出装置を兼ねることができ、塵埃清掃機能と塵埃排出機能を持つ空気調和機を小型かつ安価に実現することができる。 The filter device for an air conditioner of the present invention switches between a dust cleaning function and a dust discharge function by an opening / closing plate.
As a result, the suction / exhaust device can serve as both a dust cleaning device and a dust discharging device, and an air conditioner having a dust cleaning function and a dust discharging function can be realized in a small and inexpensive manner.

本発明の空気調和機のフィルター装置は、強い吸引清掃性能の実現と、吸引排気装置および排気ダクト内部、吸引排気装置の開閉板への塵埃堆積の防止を両立することができる。   The filter device of the air conditioner of the present invention can achieve both strong suction cleaning performance and prevention of dust accumulation on the inside of the suction / exhaust device and the exhaust duct and on the opening / closing plate of the suction / exhaust device.

第１の発明は、エアフィルターと、吸引ノズルと、前記吸引ノズルに連通された吸引排気装置を具備し、前記吸引排気装置には開口部と開閉板と開閉駆動手段を設け、前記開閉板にシール材を貼付したフィルター装置において、前記シール材の表面を埃が付着しにくい材質にすることで、塵埃がシール材の表面に付着しにくくなり、前記開閉板への塵埃堆積を防止することができる。   A first invention includes an air filter, a suction nozzle, and a suction / exhaust device communicating with the suction nozzle. The suction / exhaust device is provided with an opening, an opening / closing plate, and an opening / closing driving means. In the filter device to which the sealing material is attached, by making the surface of the sealing material difficult to adhere to dust, it becomes difficult for the dust to adhere to the surface of the sealing material, and dust accumulation on the opening / closing plate can be prevented. it can.

第２の発明は、第１の発明の空気調和機のフィルター装置において、吸引清掃後に、前記開閉板の開動作を行うことで、吸引風量が増大し、吸引排気装置および排気ダクト内に堆積した塵埃を確実に排出するものである。   According to a second aspect of the present invention, in the filter device of the air conditioner of the first aspect, after the suction cleaning, the opening / closing plate is opened to increase the amount of suction air and accumulate in the suction exhaust unit and the exhaust duct. Dust is surely discharged.

第３の発明は、第１の発明の空気調和機のフィルター装置において、前記開閉板によって塵埃清掃機能と塵埃排出機能を切り替えるようにしたもので、同じ吸引排気装置で塵埃清掃と塵埃排出を行うことができるため、高機能ながら小型で安価な空気調和機にすることができるものである。なお、塵埃清掃機能とは、吸引ノズルを用いてフィルター装置に付着した塵埃を吸引することを主な機能とするものであり、塵埃排出機能とは、吸引排気装置および排気ダクト内に堆積した塵埃を屋外に排出することを主な機能とするものをいう。また塵埃排出時には、屋内の換気も同時に行うことができる。
以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 According to a third aspect of the present invention, in the filter device of the air conditioner of the first aspect, the dust cleaning function and the dust discharge function are switched by the opening / closing plate, and the dust suction function and the dust discharge function are performed by the same suction / exhaust device. Therefore, the air conditioner can be made small and inexpensive while having high functionality. The dust cleaning function has a main function of sucking dust adhering to the filter device using a suction nozzle, and the dust discharging function is dust accumulated in the suction exhaust device and the exhaust duct. The main function is to discharge to the outdoors. When dust is discharged, indoor ventilation can be performed at the same time.
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１は、本発明の実施の形態１における空気調和機のフィルター装置の全体構成図を示すものである。
図１において、本発明の空気調和機のフィルター装置は、フィルター枠１ａとフィルター網１ｂから構成されるエアフィルター１と、エアフィルター１の表面に沿って移動可能な吸引ノズル２を設け、吸引ノズル２はフィルター枠１ａの上下端に設置されたガイドレール３により、エアフィルター１と一定の距離を保って、左右に円滑に移動することができる。吸引ノズル２には吸引ダクト４が連結され、さらに吸引ダクト４は、吸引排気装置５に連結される。吸引ダクト４は吸引ノズル２の移動に差し支えないように折り曲げ可能なダクトで形成される。さらに、吸引排気装置５には排気ダクト６が連結され、室外へ引き回される。空気調和機本体の内部には、熱交換器とファンが配設されており、本体の前面から上面にわたり形成される複数の吸い込み口から、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、前記吸い込み口と熱交換器との間に設けたエアフィルター１で取り除かれる。エアフィルター１上に付着した塵埃は、吸引ノズル２、吸引ダクト４、吸引排気装置５、排気ダクト６という順番に経由して室外へ排出される。 (Embodiment 1)
FIG. 1 shows an overall configuration diagram of a filter device for an air conditioner according to Embodiment 1 of the present invention.
In FIG. 1, the filter device of the air conditioner of the present invention is provided with an air filter 1 composed of a filter frame 1a and a filter net 1b, and a suction nozzle 2 movable along the surface of the air filter 1, 2 can be smoothly moved to the left and right while maintaining a certain distance from the air filter 1 by guide rails 3 installed at the upper and lower ends of the filter frame 1a. A suction duct 4 is connected to the suction nozzle 2, and the suction duct 4 is further connected to a suction exhaust device 5. The suction duct 4 is formed of a duct that can be bent so as not to interfere with the movement of the suction nozzle 2. Further, an exhaust duct 6 is connected to the suction exhaust device 5 and is routed outside the room. A heat exchanger and a fan are arranged inside the air conditioner main body, and air is sucked in by the operation of the fan from a plurality of suction ports formed from the front surface to the upper surface of the main body. Drifting dust is removed by an air filter 1 provided between the suction port and the heat exchanger. Dust adhering to the air filter 1 is discharged out of the room through the suction nozzle 2, the suction duct 4, the suction exhaust device 5, and the exhaust duct 6.

図２および図３は、本発明の実施の形態１における空気調和機のフィルター装置の吸引排気装置の構造を示すもので、図２は開閉板８の開状態、図３は開閉板８の閉状態を示す図である。また図中の白矢印は吸引される風を表している。   2 and 3 show the structure of the suction / exhaust device of the filter device of the air conditioner according to Embodiment 1 of the present invention. FIG. 2 shows the open state of the opening / closing plate 8, and FIG. It is a figure which shows a state. Moreover, the white arrow in a figure represents the wind attracted | sucked.

図２および図３において、吸引排気装置５はシロッコファン７を内蔵し、シロッコファン７をモーターで高速回転させることで吸引力を発揮する。吸引排気装置５の吸引側には、吸引ダクト４が連結され、排気側には排気ダクト６が連結される。さらに、吸引排気装置５の吸引側に開口部１０が設けられており、この開口部１０はステッピングモーター９によって開閉板８が駆動されることで開閉を行うことができるようになっており、これによって開口部１０の開閉弁として機能するようになっている。開口部１０は吸引排気装置５よりも下流の風量を増大させるために必要となるものであるが、塵埃清掃動作中に開口部１０を開いたままにしておくと、吸引排気装置５にて吸引される風は、開口部１０および吸引ノズル２から吸引される。しかし開口部１０の面積が、吸引ノズル２の吸い込み口よりも大きいため、吸引ノズル２における吸引力が低下してしまう。そのため塵埃清掃動作中には開閉板８で開口部１０を閉めた状態にしておかなければならない。   2 and 3, the suction / exhaust device 5 has a built-in sirocco fan 7, and exerts a suction force by rotating the sirocco fan 7 with a motor at high speed. The suction duct 4 is connected to the suction side of the suction exhaust apparatus 5, and the exhaust duct 6 is connected to the exhaust side. Further, an opening 10 is provided on the suction side of the suction / exhaust device 5, and this opening 10 can be opened and closed by driving an opening / closing plate 8 by a stepping motor 9. Therefore, it functions as an on-off valve for the opening 10. The opening 10 is necessary to increase the air volume downstream of the suction exhaust device 5. If the opening 10 is left open during the dust cleaning operation, the suction exhaust device 5 performs suction. The wind to be sucked is sucked from the opening 10 and the suction nozzle 2. However, since the area of the opening 10 is larger than the suction port of the suction nozzle 2, the suction force at the suction nozzle 2 is reduced. Therefore, the opening 10 must be closed with the opening / closing plate 8 during the dust cleaning operation.

また、開閉板８や開閉板８と当接する開口部１０の近傍に塵埃が付着して、開閉板８が完全に閉まらない場合がある。それに対して、開閉板８の表面にシール材１１としてＥＰＴ（エチレンプロピレンゴム）の発泡材を貼付することで、シール材１１やシール材１１
と当接する開口部１０の近傍に塵埃が付着したとしても、シール材１１が柔軟に変形することで開閉板８は確実に閉じる。またシール材１１の表面に塵埃が堆積する場合があるが、シール材１１の表面に埃が付着しにくい材料を用いることで解決している。
以上のように構成された空気調和機のフィルター装置について、以下その動作、作用を説明する。 In addition, dust may adhere to the vicinity of the opening / closing plate 8 or the opening 10 that contacts the opening / closing plate 8, and the opening / closing plate 8 may not be completely closed. On the other hand, by sticking an EPT (ethylene propylene rubber) foamed material as the sealing material 11 to the surface of the opening / closing plate 8, the sealing material 11 or the sealing material 11 is used.
Even if dust adheres to the vicinity of the opening 10 that contacts the opening / closing plate 8, the opening / closing plate 8 is reliably closed by the flexible deformation of the sealing material 11. Moreover, although dust may accumulate on the surface of the sealing material 11, this is solved by using a material that does not easily adhere to the surface of the sealing material 11.
About the filter apparatus of the air conditioner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

本発明の空気調和機のフィルター装置の吸引清掃後において、吸引排気装置５の開閉板８を開状態にすると、吸引排気装置５を通過するほぼすべての風は、開口部１０から吸引されることになる。吸引排気装置５の方が吸引ノズル２よりも大きいので、開口部１０の面積は、吸引ノズル２の吸い込み口よりも大きく設けることができる。   When the open / close plate 8 of the suction / exhaust device 5 is opened after the suction cleaning of the filter device of the air conditioner of the present invention, almost all the wind passing through the suction / exhaust device 5 is sucked from the opening 10. become. Since the suction exhaust device 5 is larger than the suction nozzle 2, the area of the opening 10 can be provided larger than the suction port of the suction nozzle 2.

つまり開口部１０で吸引される風の風速は遅く、吸引排気装置５の通風抵抗は非常に低いものとなる。さらに、吸引ノズル２と吸引ダクト４には風が流れないので、吸引ノズル２の通風抵抗および吸引ダクト４の通風抵抗は０に近い値となる。従って、通風抵抗の合計値は排気ダクト６の通風抵抗に近い値となり、非常に低くできる。この結果、吸引排気装置５内のシロッコファン７の回転数が同じであっても、吸引排気装置５と排気ダクト６を流れる風量を著しく増大させることができ、吸引排気装置５の内部や排気ダクト６に堆積した塵埃を押し流して、室外へ排出することができるようになる。もちろん、その際にシロッコファン７のブレードに付着した塵埃を吹き飛ばすことができ、シロッコファン７が塵埃で詰まることも防止することができる。   That is, the wind speed of the wind sucked through the opening 10 is slow, and the ventilation resistance of the suction exhaust device 5 is very low. Further, since no wind flows through the suction nozzle 2 and the suction duct 4, the ventilation resistance of the suction nozzle 2 and the ventilation resistance of the suction duct 4 are values close to zero. Therefore, the total value of the ventilation resistance is close to the ventilation resistance of the exhaust duct 6 and can be very low. As a result, even if the rotation speed of the sirocco fan 7 in the suction / exhaust device 5 is the same, the amount of air flowing through the suction / exhaust device 5 and the exhaust duct 6 can be remarkably increased. The dust accumulated on 6 can be swept away and discharged to the outside. Of course, the dust attached to the blade of the sirocco fan 7 can be blown off at that time, and the sirocco fan 7 can be prevented from being clogged with dust.

以上のように、開閉板８を開いた時は、塵埃排出機能を実現する手段として吸引排気装置５を用い、開閉板８を閉じた時は、吸引ノズル２の吸い込み口から塵埃を吸引する塵埃清掃機能を実現する手段として吸引排気装置５を用いることができる。すなわち、同じ吸引排気装置５で塵埃清掃機能と塵埃排出機能を実現できることになる。またこの時の風量は、シロッコファン７の大きさや吸引排気装置５の大きさによっては、通常の家屋において換気を行えるほどの風量になるので、塵埃排出機能を実現するとともに、家屋内の換気効果も発揮することができる。   As described above, when the opening / closing plate 8 is opened, the suction / exhaust device 5 is used as a means for realizing the dust discharging function, and when the opening / closing plate 8 is closed, dust is sucked from the suction port of the suction nozzle 2. The suction / exhaust device 5 can be used as a means for realizing the cleaning function. That is, the dust suction function and the dust discharge function can be realized with the same suction / exhaust device 5. Further, the air volume at this time becomes an air volume that can be ventilated in a normal house depending on the size of the sirocco fan 7 and the size of the suction / exhaust device 5, so that the dust exhaust function is realized and the ventilation effect in the house is achieved. Can also be demonstrated.

また、開閉板８を閉じることによって開口部１０が完全に閉じられなければ、開口部１０と吸引ノズル２の吸い込み口の両方から吸引してしまうことになり、塵埃清掃性能が低下することになる。しかし開閉板８や開閉板８と当接する開口部１０の近傍に塵埃が付着して、完全に開閉板８で開口部１０を閉じることができないこともありうるため、開閉板８の表面に柔らかくて柔軟に変形し、なおかつ永久変形の少ないシール材１１を貼付して、開口部１０からの吸引を防ぐようにする必要がある。シール材１１の材質には、ＥＰＴなどの柔軟な発砲材などを用いても良いが、圧縮変形に強い耐性のあるゲル材、ポロンなどのウレタン材などを用いても良い。なお、シール材１１の材質はこれらに限定されるものではなく、同等の効果を奏するものであればよい。   Moreover, if the opening part 10 is not completely closed by closing the opening-and-closing plate 8, it will attract | suck from both the opening part 10 and the suction inlet of the suction nozzle 2, and dust cleaning performance will fall. . However, since dust may adhere to the opening / closing plate 8 or the vicinity of the opening 10 that contacts the opening / closing plate 8 and the opening 10 cannot be completely closed by the opening / closing plate 8, the surface of the opening / closing plate 8 is soft. Therefore, it is necessary to apply the sealing material 11 that is deformed flexibly and has little permanent deformation to prevent suction from the opening 10. As the material of the sealing material 11, a flexible foamed material such as EPT may be used, but a gel material having a strong resistance to compression deformation, a urethane material such as poron, or the like may be used. In addition, the material of the sealing material 11 is not limited to these, What is necessary is just to show an equivalent effect.

また、シール材１１の表面がざらざら、もしくはベトベトしていると、塵埃がシール材１１に付着し、成長して埃塊になり、シロッコファン７に詰まり、ロックといった不具合が発生する恐れがある。そのような不具合に対応するために、開閉板８のシール材１１は、柔らかくて柔軟に変形する材質と、表面に塵埃が付着しにくい材質とを接着させた多層構造になったものを用いてもよい。例えば、シール材１１には、柔らかくて柔軟に変形する物質に、表面に塵埃が付着しにくく、非常に薄いＰＥＴ（ポリエチレンテレフタレート）やＰＥＮ（ポリエチレンナフタレート）などのフィルム材を貼り付けたものを用いることで、シール材１１の表面に埃が付着しないようにする。塵埃が付着しにくい材質には、例えば、ＥＰＴ、ゴム材、シリコン材やウレタン材、ＰＥＴやＰＥＮのフィルム材など表面が滑らかである材質を用いるが、これに限定されるものではなく、同等の効果を奏するものであればよい。   Further, if the surface of the sealing material 11 is rough or sticky, dust adheres to the sealing material 11 and grows to become a dust lump, which may cause problems such as clogging the sirocco fan 7 and locking. In order to deal with such a problem, the sealing material 11 of the opening / closing plate 8 uses a multilayer structure in which a soft and flexible deformable material and a material to which dust does not easily adhere are adhered. Also good. For example, the sealing material 11 is made of a material that is soft and flexibly deformed, and is attached with a very thin film material such as PET (polyethylene terephthalate) or PEN (polyethylene naphthalate) that is hard to adhere to dust on the surface. By using it, dust is prevented from adhering to the surface of the sealing material 11. For materials that are difficult to adhere to dust, for example, materials having a smooth surface such as EPT, rubber material, silicon material, urethane material, PET or PEN film material are used. Any effect may be used.

以上のように、本発明の空気調和機のフィルター装置は、吸引清掃を行った後に風量を増大させてフィルター装置内部の塵埃を室外へ排出できるので、小出力の吸引装置でも強い吸引力の確保と、確実な塵埃の排出を両立することができる。また、吸引排気装置内部の塵埃堆積の防止を図ることができるため、様々な形状のエアフィルターに利用でき、空気調和機のエアフィルターだけでなく冷却ファンを有する機器の清掃装置などにも適用できる。   As described above, the filter device of the air conditioner according to the present invention can increase the air volume after performing suction cleaning and can discharge dust inside the filter device to the outside, so that a strong suction force can be secured even with a small output suction device. And reliable dust discharge can be achieved. In addition, since dust accumulation inside the suction / exhaust device can be prevented, it can be used for air filters of various shapes, and can be applied not only to air filters of air conditioners but also to cleaning devices for equipment having cooling fans. .
