Description

本発明は、空気調和機のフィルターに付着したごみを除去するフィルター清掃装置に関するものである。 The present invention relates to a filter cleaning device for removing dust adhering to a filter of an air conditioner.

従来の空気調和機のフィルター清掃装置は、本体内部に設けられたエアーフイルタ上のごみを除去するため、エアーフィルタの上流側にごみ吸引部をもうけ、これとダクト部で吸引ファンを接続してエアフィルタに堆積するごみを吸引するようになっている。ごみ吸引部にはエアーフィルタのごみを掻き落すためのブラシが設けられ、そしてこのごみ吸引部がエアーフイルタ上を自在に移動可能とすることで手間をかけずに自動で清掃できるようになっている（例えば特許文献１参照）。
特開２００２−３４０３９５号公報 In order to remove the dust on the air filter provided inside the main body, the conventional air conditioner filter cleaning device has a dust suction part on the upstream side of the air filter, and a suction fan is connected to this with a duct part. The dust accumulated on the air filter is sucked. The dust suction part is equipped with a brush for scraping off dust from the air filter, and the dust suction part can be moved freely on the air filter so that it can be automatically cleaned without trouble. (For example, refer to Patent Document 1).

しかしながら、従来のフイルタ清掃装置においては、ごみをブラシで掻き取りながら吸引するために、ごみが飛散して空気調和機内部が汚れたり、ブラシにごみが大量に付着してしまい十分に吸い取れないなどの課題が生じることがあった。 However, in the conventional filter cleaning device, since dust is sucked while scraping with a brush, the dust is scattered and the inside of the air conditioner becomes dirty, or a large amount of dust adheres to the brush and cannot be absorbed sufficiently. There were cases where problems such as these occurred.

本発明は、上記課題を解決し、ごみの飛散や付着によるトラブルをなくし、フィルターのごみを確実に除去できるフイルタ清掃装置を提供する。 The present invention provides a filter cleaning device that solves the above-described problems, eliminates troubles caused by scattering and adhesion of dust, and can reliably remove dust from the filter.

前記従来の課題を解決するため、本発明のフイルタ清掃装置は、フィルターの前面に付着したごみを吸引する吸引ノズルと、フィルターを挟んで吸引ノズルと相対する位置に背板を備えるものである。これにより、ごみの吸引力を増し、吸引だけでフィルターのごみを除去することができる。 In order to solve the above-described conventional problems, the filter cleaning device of the present invention includes a suction nozzle that sucks dust attached to the front surface of a filter, and a back plate at a position facing the suction nozzle with the filter interposed therebetween. Thereby, the suction | attraction force of refuse can be increased and the dust of a filter can be removed only by suction.

本発明のフィルター清掃装置によれば、ごみ吸引力を大幅に向上させることができ、かつブラシなどを使用する必要がないので、ごみ飛びやブラシへの付着によるトラブルを防止するという効果を奏する。また、容易に構成できるという効果も奏する。 According to the filter cleaning device of the present invention, it is possible to greatly improve the dust suction force and it is not necessary to use a brush or the like. Therefore, it is possible to prevent troubles caused by dust flying and adhesion to the brush. Also, there is an effect that it can be easily configured.

以下に、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。 Embodiments of the present invention will be described below with reference to the drawings.

図１に示すように、フィルター１０１を矢印１０９の方向に空気が流れており、所定の運転状況において、フィルター１０１に付着したごみを吸引ノズル１０２が吸引して掃除を行う。また、吸引ノズル１０２は吸引ダクト１０８に加えて電磁コイル１０７を備えている。吸引ダクト１０８は吸引ファンやごみ回収容器などからなる吸引装置（図示せず）に接続される。 As shown in FIG. 1, air flows through the filter 101 in the direction of the arrow 109, and in a predetermined operating condition, the suction nozzle 102 sucks and cleans dust adhering to the filter 101. The suction nozzle 102 includes an electromagnetic coil 107 in addition to the suction duct 108. The suction duct 108 is connected to a suction device (not shown) composed of a suction fan, a waste collection container, and the like.

吸引ノズル１０２の、フィルター１０１を挟んで反対側には、背板１０３が吸引ノズル１０２に相対して配置される。背板１０３を配置することで、吸引ノズル１０２によるごみ吸引力を大幅に向上させることができる。従って、従来の技術のように、ブラシなどを使用する必要がなく、ごみ飛びやブラシへの付着によるトラブルを防止することができる。 A back plate 103 is disposed opposite to the suction nozzle 102 on the opposite side of the suction nozzle 102 across the filter 101. By disposing the back plate 103, the dust suction force by the suction nozzle 102 can be greatly improved. Therefore, it is not necessary to use a brush or the like as in the prior art, and it is possible to prevent troubles caused by dust flying or adhesion to the brush.

さらに、背板１０３にスリット１０４を設けることで、吸引される空気がフィルター１０１を通過する際の流速を上げてやることで、ごみの吸引力をさらに向上させ、所要電力の削減を図ることができる。 Furthermore, by providing the slit 104 in the back plate 103, it is possible to further increase the dust suction force and reduce the required power by increasing the flow velocity when the sucked air passes through the filter 101. it can.

ここで、ガイダー１０５はローラーを軸固定した構造で回転可能であるとともに背板１０３とフィルター１０１の距離を所定の値に保っている。ガイダー１０５がないと、吸引力のために背板１０３は吸引ノズル１０２側に引かれフィルター１０１に張りついた状態となって、フィルター１０１の清掃個所を移動させる際、背板１０３あるいはフィルター１０１を動かすことが困難になる。つまり、ガイダー１０５が背板１０３とフィルター１０１の距離を所定の値に保つことで、背板１０３あるいはフィルター１０１の移動が可能となる。 Here, the guider 105 can be rotated with a roller fixed shaft, and the distance between the back plate 103 and the filter 101 is kept at a predetermined value. Without the guider 105, the back plate 103 is pulled toward the suction nozzle 102 due to the suction force and sticks to the filter 101. When moving the cleaning part of the filter 101, the back plate 103 or the filter 101 is moved. It becomes difficult to move. That is, when the guider 105 maintains the distance between the back plate 103 and the filter 101 at a predetermined value, the back plate 103 or the filter 101 can be moved.

さらに、ガイダー１０５はローラーを回転可能の軸固定した構造とすることで、フィルター１０１と背板１０３の相対運動が円滑に行われ、振動によるごみの飛散や摺動による異音の発生を抑えることができる。なお、本実施形態では、ガイダー１０５はローラーを軸固定した構造としたが回転自在な構造であれば球体であってもさしつかえない。 Furthermore, the guider 105 has a structure in which the roller is rotatable and the shaft is fixed, so that the relative movement between the filter 101 and the back plate 103 is smoothly performed, and the generation of abnormal noise due to dust scattering and sliding due to vibration is suppressed. Can do. In this embodiment, the guider 105 has a structure in which a roller is fixed to the shaft, but a spherical structure may be used as long as the structure is rotatable.

また、吸引ノズル１０２には、電磁コイル１０７が装備され、背板１０３には鉄板１０６が装備されている。フィルター１０１の掃除中は電磁コイル１０７を動作させ鉄板１０６を引き寄せることにより、吸引ノズル１０２の移動に追従して背板１０３が移動したり、あるいはフィルター１０１が駆動した場合に、吸引ノズル１０２に相対する位置に背板１０３が留めたりすることができる。しかも、背板１０３の支持部材は必要なく、容易に構成することができる。 The suction nozzle 102 is equipped with an electromagnetic coil 107, and the back plate 103 is equipped with an iron plate 106. While the filter 101 is being cleaned, the electromagnetic coil 107 is operated to attract the iron plate 106, so that the back plate 103 moves following the movement of the suction nozzle 102, or when the filter 101 is driven, The back plate 103 can be fastened to the position where it is placed. In addition, a support member for the back plate 103 is not necessary and can be easily configured.

ここで、電磁コイル１０７と鉄板１０６を用いて構成したが、それぞれに磁石を使用しても同様の効果を得ることができる。またここでは鉄板で説明したが、鉄板に限定されるものではなく磁性材料であれば何でも良いのは言うまでもない。そして、磁石を使用する場合には、配線の必要がなく、電力も使用せずに装置を構成することができる。一方、電磁コイルと鉄板を使用する場合には磁力による引力を入り切りできるので、状況に応じて吸引ノズル１０２と背板１０３の相対する構成を解除し、例えば吸引ノズル１０２を換気などの他の用途に使用することも容易である。 Here, although it comprised using the electromagnetic coil 107 and the iron plate 106, even if it uses a magnet for each, the same effect can be acquired. Further, although the iron plate has been described here, it is needless to say that the magnetic material is not limited to the iron plate. And when using a magnet, an apparatus can be comprised without the need of wiring and using electric power. On the other hand, when an electromagnetic coil and an iron plate are used, the attractive force due to the magnetic force can be turned on and off, so that the opposing configuration of the suction nozzle 102 and the back plate 103 is canceled depending on the situation, for example, the suction nozzle 102 is used for other purposes such as ventilation It is also easy to use.
