The brush-shaped cleaning member 46b that scrapes off dust adhering to the surface of the air filter 29, and each end portion of the cleaning member 46b and the side wall of the cleaning body storage portion 47 are fixed to the shaft body 46a. At the same time, it is constituted by a gear 46 c that meshes with a rack gear 39 provided on the frame 36 of the air filter 29. In this embodiment, the pitch between the gears 46 c provided at both ends of the rotary cleaning body 46 is the same as the pitch in the vertical direction of the rack gear 39 provided on the frame body 36 of the air filter 29. That is, the gears 46 c provided at both ends of the rotary cleaning body 46 are engaged with the two rack gears 39 provided on the frame body 36 of the air filter 29.

以上のように構成された本実施例における空気調和機用清掃装置の動作、作用について、説明する。尚、図７は、説明を容易にするために、エアフィルター２７を展開して示した図である。   The operation and action of the cleaning device for an air conditioner in the present embodiment configured as described above will be described. FIG. 7 is an expanded view of the air filter 27 for ease of explanation.

エアーフィルター２９の清掃を開始するに当たり、本実施例では、図７に示すように、吸引ノズル３０のベルト４２に設けた回転清掃体４６は、あらかじめ、エアーフィルター２９の最下段の右端に寄せられている（初期位置）。そして、図示しない、エアーフィルタークリーニングスイッチを操作すると、吸引手段３２の運転が開始すると共に、ノズル移動手段３４が動作して、吸引ノズル３０が左方向に移動開始する。このとき、回転清掃体４６の両端のギヤ４６ｃが、エアーフィルター２９のガイドレール下３８ｂに設けたラックギヤ３９と、最下段の横桟３６ａのラックギヤ３９と噛み合っているので、吸引ノズル３０の移動に伴い、回転清掃体４６が回転し、回転清掃体４６の清掃部材４６ｂが、エアーフィルター２９のフィルター網３７に付着した塵埃を効率よく、かつ確実に掻き取る。   In starting the cleaning of the air filter 29, in this embodiment, as shown in FIG. 7, the rotary cleaning body 46 provided on the belt 42 of the suction nozzle 30 is brought close to the right end of the lowermost stage of the air filter 29 in advance. (Initial position). When an air filter cleaning switch (not shown) is operated, the operation of the suction means 32 is started, and the nozzle moving means 34 is operated to start the suction nozzle 30 moving leftward. At this time, the gears 46c at both ends of the rotary cleaning body 46 mesh with the rack gear 39 provided on the lower guide rail 38b of the air filter 29 and the rack gear 39 of the lowermost horizontal rail 36a. Accordingly, the rotary cleaning body 46 rotates, and the cleaning member 46b of the rotary cleaning body 46 scrapes off dust adhering to the filter mesh 37 of the air filter 29 efficiently and reliably.

清掃部材４６ｂで掻き取られ塵埃は、吸引手段３２の吸引力により、ノズル本体４０、吸引ダクト３１、吸引手段３２、排気ダクト３３を順に通って、瞬時に室外に排出される。   The dust scraped off by the cleaning member 46 b is discharged through the nozzle body 40, the suction duct 31, the suction means 32, and the exhaust duct 33 in order by the suction force of the suction means 32 and is instantaneously discharged outside the room.

吸引ノズル３０が、エアーフィルター２９の左端に達して、エアーフィルター２９の最下段の部分の清掃が終わると、自動的に、ローラ駆動手段４４を駆動して、ベルト４２を、回転清掃体４６が、最下段の横桟３６ａと、下から２段目の横桟３６ａとの間に位置するように、上方に移動させる。そして、ノズル移動手段３４を逆転させて、吸引ノズル３０を右方向に移動させながら、同様にエアーフィルター２９の清掃を行なう。   When the suction nozzle 30 reaches the left end of the air filter 29 and the cleaning of the lowermost part of the air filter 29 is finished, the roller driving means 44 is automatically driven to rotate the belt 42 and the rotary cleaning body 46 Then, it is moved upward so as to be positioned between the lowermost horizontal beam 36a and the second horizontal beam 36a from the bottom. Then, the air filter 29 is similarly cleaned while the nozzle moving means 34 is reversed and the suction nozzle 30 is moved in the right direction.

そして、図７の矢印で示すように、吸引ノズル３０と、回転清掃体４６を順次移動させることにより、エアーフィルター２９の全面を確実に清掃することができる。   Then, as indicated by the arrows in FIG. 7, the entire surface of the air filter 29 can be reliably cleaned by sequentially moving the suction nozzle 30 and the rotary cleaning body 46.

本実施例では、図７に示すように、回転清掃体４６が、エアーフィルター２９の最上段の左端に達して、エアーフィルター２９全面の清掃を終えるが、この後、次回のエアーフィルター２９の清掃のために、自動的に、ノズル移動手段３４とローラ駆動手段４４が駆動して、回転清掃体４６を、エアーフィルター２９の最下段の右端（初期位置）まで移動させるようにしている。   In this embodiment, as shown in FIG. 7, the rotary cleaning body 46 reaches the uppermost left end of the air filter 29 and finishes the cleaning of the entire surface of the air filter 29. Thereafter, the next cleaning of the air filter 29 is performed. Therefore, the nozzle moving means 34 and the roller driving means 44 are automatically driven to move the rotary cleaning body 46 to the lowermost right end (initial position) of the air filter 29.

以上のように、本実施例によれば、エアフイルター２９の表面に付着した塵埃を、回転清掃体４６で回転しながら掻き取るので、塵埃の除去性能が飛躍的に向上する。又、エアフィルター２９をベルト状にしたり、移動させたりする必要が無いので、エアフィルター２９に必要以上の強度を持たせたり、必要以上に精度よく仕上げる必要が無く、薄くしかも、安価に構成でき、結果的に、空気調和機の小型化を図ることができる。   As described above, according to the present embodiment, dust attached to the surface of the air filter 29 is scraped off while being rotated by the rotary cleaning body 46, so that the dust removal performance is greatly improved. In addition, since it is not necessary to make the air filter 29 into a belt shape or to move it, it is not necessary to give the air filter 29 strength more than necessary or to finish it more precisely than necessary, and it can be made thin and inexpensive. As a result, the size of the air conditioner can be reduced.

また、エアフイルター２９が局部的に湾曲していても、回転清掃体４６の軸体４６ａは可撓性を有するので、回転清掃体４６がエアフイルター２９の湾曲部分に沿って撓み、優れた塵埃除去性能を、エアフイルター２９の全面に渡って安定して発揮することができる。   Further, even if the air filter 29 is locally curved, the shaft body 46a of the rotary cleaning body 46 has flexibility, so that the rotary cleaning body 46 bends along the curved portion of the air filter 29 and is excellent in dust. The removal performance can be stably exhibited over the entire surface of the air filter 29.

また、回転清掃体４６を、吸引ノズル３０の移動を駆動源として、すなわち、吸引ノズル３０の移動に伴って、回転清掃体４６を回転駆動するようにしたので、回転清掃体４６を駆動するための専用の駆動手段が不要になり、清掃装置２７を安価に提供することができる。特に、駆動手段としてモータなどを用いる場合は、それようの電気配線も不要になるので、組み立ても容易になる。   In addition, since the rotary cleaning body 46 is driven to rotate with the movement of the suction nozzle 30 as a drive source, that is, with the movement of the suction nozzle 30, the rotary cleaning body 46 is driven. Therefore, the cleaning device 27 can be provided at low cost. In particular, when a motor or the like is used as the driving means, such electrical wiring is not required, and assembly is facilitated.

さらに、上記実施例における清掃装置２７を、熱交換器（図示せず）と、前記熱交換器の上流側に配され流入する空気に含まれる塵埃を捕獲するエアフイルター（図示せず）とを備えた空気調和機に搭載し、清掃装置２７で、エアフイルターを清掃するようにすれば、エアフィルターの耐久性を維持しながら塵埃の掻き取り性能に優れた空気調和機を提供することもできる。   Further, the cleaning device 27 in the above embodiment includes a heat exchanger (not shown) and an air filter (not shown) that captures dust contained in the inflowing air that is arranged upstream of the heat exchanger. If the air filter is mounted on the provided air conditioner and the air filter is cleaned by the cleaning device 27, it is possible to provide an air conditioner having excellent dust scraping performance while maintaining the durability of the air filter. .

なお、上記実施例では、回転清掃体４６の軸体４６ａに可撓性を持たせるために、軸体４６ａをナイロンなどの柔軟性に富んだ材料で形成したが、金属や硬質の樹脂などからなるバネ材や、コイル部材、或いは、軸体４６ａを複数に分割して、それらを回動自在に連結して、構造的に可撓性を持たせるようにしてもよく、本発明は、軸体４６ａに可撓性を持たせるための方法については、特に限定するものではない。   In the above embodiment, the shaft body 46a is made of a flexible material such as nylon in order to give the shaft body 46a of the rotary cleaning body 46 flexibility. The spring member, the coil member, or the shaft body 46a may be divided into a plurality of parts, and these may be rotatably connected to provide structural flexibility. The method for giving flexibility to the body 46a is not particularly limited.

以上のように、本発明にかかる空気調和機用清掃装置及び空気調和機は、従来のエアフィルターの耐久性を維持しながら、小型で、塵埃の除去性能に優れたもので、家庭用、業務用の各種空気調和機は勿論、空気清浄機、換気装置などエアフィルターを有する各種機器に適用できるものである。   As described above, the air conditioner cleaning device and the air conditioner according to the present invention are small in size and excellent in dust removal performance while maintaining the durability of the conventional air filter. It can be applied not only to various air conditioners, but also to various devices having an air filter such as an air purifier and a ventilator.
