しかしながら、上記特許文献１に記載された従来の空気調和機用清掃装置の構成では、ブラシ体１０で、塵埃を掻き取るとはいえ、エアフィルター２の表面を一方向に撫でるだけなので、塵埃の除去性能に限界があった。   However, in the configuration of the conventional cleaning device for an air conditioner described in Patent Document 1, although the dust is scraped off with the brush body 10, the surface of the air filter 2 is only boiled in one direction. There was a limit to the removal performance.

また、上記特許文献２に記載された従来の空気調和機用清掃装置の構成では、エアフィルター１３がベルト状に形成されているので、空気調和機の奥行き寸法が大きくなると共に、駆動軸１５と従動軸１６間に張架されて移動するため、早期に痛みやすいという課題があった、   Further, in the configuration of the conventional air conditioner cleaning device described in Patent Document 2, since the air filter 13 is formed in a belt shape, the depth dimension of the air conditioner increases, and the drive shaft 15 and Because it was stretched between the driven shafts 16 and moved, there was a problem that it was easy to hurt early.

本発明は、上記従来の課題を解決するもので、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空気調和機用清掃装置と、空気調和機を提供することを目的とするものである。   The present invention solves the above-described conventional problems, and provides an air conditioner cleaning device and an air conditioner that are small and excellent in dust removal performance while maintaining the durability of a conventional air filter. It is for the purpose.

前記従来の課題を解決するために、本発明の空気調和機用清掃装置は、空気調和機に内蔵されたエアフィルターの上流側表面に沿って移動すると共に前記エアフィルターに対向する面の長手方向に開口部を有するノズル本体と、該ノズル本体に連結された吸引手段と、前記開口部を覆うと共に前記ノズル本体の長手方向に沿って移動可能に設けられた帯状体と、該帯状体の長手方向と直交する方向で、エアフィルターに付着した塵埃を掻き取る回転清掃体と、前記帯状体を移動させる駆動手段と、前記帯状体に前記回転清掃体を回転自在に収納する清掃体収納部とを備え、該清掃体収納部は、エアフィルター側に開口すると共に、前記回転清掃体が臨む吸引口と、前記ノズル本体内部と連通する連通孔とを有し、前記清掃体収納部と、前記回転清掃体とは、前記帯状体の移動と共に移動することを特徴とするものであり、エアフィルターの表面に付着した塵埃を、回転清掃体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。 In order to solve the above-mentioned conventional problems, a cleaning device for an air conditioner according to the present invention moves along the upstream surface of an air filter built in the air conditioner and has a longitudinal direction of a surface facing the air filter. A nozzle body having an opening in the nozzle body , suction means connected to the nozzle body , a belt- like body that covers the opening and is movable along the longitudinal direction of the nozzle body, and a longitudinal direction of the belt- like body A rotating cleaning body that scrapes off dust adhering to the air filter in a direction orthogonal to the direction, a driving means that moves the band-shaped body, and a cleaning body storage portion that rotatably stores the rotary cleaning body in the band-shaped body. The cleaning body storage portion has an opening on the air filter side, a suction port facing the rotary cleaning body, and a communication hole communicating with the inside of the nozzle body, the cleaning body storage portion , Times The cleaning body is characterized by moving with the movement of the belt-like body, and dust adhering to the surface of the air filter is scraped off while rotating with the rotary cleaning body, so that the dust removal performance is dramatically improved. To improve. In addition, since it is not necessary to make the air filter into a belt or move, it is not necessary to give the air filter more strength than necessary or to finish it more precisely than necessary, and it can be configured thinly and inexpensively. Therefore, it is possible to reduce the size of the air conditioner.

また、吸引ノズルを、その長手方向と直交する方向に、繰り返し移動させながら、帯状体を順次移動させるようにすれば、エアフィルターの全面を清掃することができるので、吸引口の開口面積を小さくし、回転清掃体も小型化することが出来る。また、吸引口の開口面積を小さくし、回転清掃体を小型化することで、吸引手段や、回転清掃体を駆動する駆動源も小型化することができる。   In addition, if the belt-like body is sequentially moved while repeatedly moving the suction nozzle in a direction perpendicular to the longitudinal direction, the entire surface of the air filter can be cleaned, so the opening area of the suction port is reduced. In addition, the rotary cleaning body can be reduced in size. Further, by reducing the opening area of the suction port and downsizing the rotary cleaning body, the suction means and the drive source for driving the rotary cleaning body can also be downsized.

また、本発明の空気調和機は、熱交換器と、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ィルターと、請求項１〜３のいずれか1項に記載の空気調和機用清掃装置を備えたもので、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ができる。   The air conditioner according to the present invention includes a heat exchanger, an air filter that is disposed on the upstream side of the heat exchanger and captures dust contained in the flowing air, and any one of claims 1 to 3. The air conditioner cleaning apparatus described above is provided, and an air conditioner excellent in dust scraping performance while maintaining the durability of the air filter can be provided.

本発明の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、しかもエアフィルターの塵埃の除去性能に優れたものである。   The cleaning device for an air conditioner and the air conditioner according to the present invention are small in size and excellent in dust removal performance of the air filter while maintaining the durability of the conventional air filter.

第１の発明は、空気調和機に内蔵されたエアフィルターの上流側表面に沿って移動すると共に前記エアフィルターに対向する面の長手方向に開口部を有するノズル本体と、該ノズル本体に連結された吸引手段と、前記開口部を覆うと共に前記ノズル本体の長手方向に沿って移動可能に設けられた帯状体と、該帯状体の長手方向と直交する方向で、エアフィルターに付着した塵埃を掻き取る回転清掃体と、前記帯状体を移動させる駆動手段と、前記帯状体に前記回転清掃体を回転自在に収納する清掃体収納部とを備え、該清掃体収納部は、エアフィルター側に開口すると共に、前記回転清掃体が臨む吸引口と、前記ノズル本体内部と連通する連通孔とを有し、前記清掃体収納部と、前記回転清掃体とは、前記帯状体の移動と共に移動することを特徴とするものであり、エアフィルターの表面に付着した塵埃を、回転清掃体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。また、空気調和機に内蔵されたエアフィルターが湾曲している場合、吸引ノズルもそれに合わせて湾曲させると共に、エアフィルターに沿って移動させるが、このとき、回転清掃体が、吸引ノズルの長手方向と直交するように配することで、回転清掃体を、エアフィルターの湾曲部にスムーズに沿わせながら移動させることができ、エアフィルターの表面からの塵埃の除去漏れを防止することができる。 According to a first aspect of the present invention, there is provided a nozzle body that moves along an upstream surface of an air filter built in an air conditioner and has an opening in a longitudinal direction of a surface facing the air filter, and is connected to the nozzle body.

The Is intended to symptoms, the dust adhering to the surface of the air filter, since the scraping while rotating the rotary cleaning body, dust removal performance is dramatically improved. In addition, since it is not necessary to make the air filter into a belt or move, it is not necessary to give the air filter more strength than necessary or to finish it more precisely than necessary, and it can be configured thinly and inexpensively. Therefore, it is possible to reduce the size of the air conditioner. In addition, when the air filter built in the air conditioner is curved, the suction nozzle is also curved along with it and moved along the air filter. At this time, the rotary cleaning body is moved in the longitudinal direction of the suction nozzle. By arranging them so as to be orthogonal to each other, the rotary cleaning body can be moved while being smoothly along the curved portion of the air filter, and the removal of dust from the surface of the air filter can be prevented.

また、吸引ノズルを、その長手方向と直交する方向に、繰り返し移動させながら、帯状体を順次移動させるようにすれば、エアフィルターの全面を清掃することができるので、吸引口の開口面積を小さくし、回転清掃体も小型化することが出来る。また、吸引口の開口面積を小さくし、回転清掃体を小型化することで、吸引手段や、回転清掃体を駆動する駆動源も小型化することができる。   In addition, if the belt-like body is sequentially moved while repeatedly moving the suction nozzle in a direction perpendicular to the longitudinal direction, the entire surface of the air filter can be cleaned, so the opening area of the suction port is reduced. In addition, the rotary cleaning body can be reduced in size. Further, by reducing the opening area of the suction port and downsizing the rotary cleaning body, the suction means and the drive source for driving the rotary cleaning body can also be downsized.

第２の発明は、特に、第１の発明の回転清掃体を、帯状体の駆動と連動して、回転駆動するようにしたもので、回転清掃体を駆動するための専用の駆動手段が不要になり、空気調和機用清掃装置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 the second aspect of the invention, in particular, the rotary cleaning body of the first aspect of the invention is driven to rotate in conjunction with the driving of the belt-like body, and no dedicated drive means for driving the rotary cleaning body is required. Thus, the air conditioner cleaning device 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.

４９は、ノズル本体４０の内壁４０ｂに一体的に、且つ長手方向に形成されたラックギヤ壁で、その上端には、回転清掃体４６のギヤ４６ｃに噛み合うラックギヤ４９ａが延設されている。   49 is a rack gear wall formed integrally with the inner wall 40b of the nozzle body 40 in the longitudinal direction, and a rack gear 49a that meshes with the gear 46c of the rotary cleaning body 46 is extended at the upper end thereof.

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６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. 6 is an expanded view of the air filter 27 for ease of explanation.

エアフィルター２９の清掃を開始するに当たり、本実施例では、図６に示すように、吸引ノズル３０を、予めエアフィルター２９の右端に位置させると共に、ローラ駆動手段４４で、吸引口４７ａが最も下になるように帯状体４２を移動させておく。すなわち、この状態では、吸引口４７ａと共に回転清掃体４６が、エアフィルター２９の最下段の右端に寄せられている（以下、この位置を「初期位置」という）。   In starting the cleaning of the air filter 29, in this embodiment, as shown in FIG. 6, the suction nozzle 30 is positioned in advance at the right end of the air filter 29 and the suction port 47 a is at the lowest position by the roller driving means 44. The belt-like body 42 is moved so that That is, in this state, the rotary cleaning body 46 is brought together with the suction port 47a to the right end of the lowermost stage of the air filter 29 (hereinafter, this position is referred to as “initial position”).

そして、図示しないエア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、ローラー駆動手段４４が駆動して、帯状体４２が上方に移動開始する。これにより、吸引口４７ａと回転清掃体４６も上方に移動する。このとき、回転清掃体４６の両端のギヤ４６ｃが、ラックギヤ壁４９の上端に形成されたラックギヤ４９ａと噛み合っているので、帯状体４２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。   When an air filter cleaning switch (not shown) is operated, the operation of the suction unit 32 is started, and the roller driving unit 44 is driven, so that the belt-like body 42 starts to move upward. As a result, the suction port 47a and the rotary cleaning body 46 also move upward. At this time, since the gears 46c at both ends of the rotary cleaning body 46 mesh with the rack gear 49a formed at the upper end of the rack gear wall 49, the rotary cleaning body 46 rotates with the movement of the belt-like body 42, and the rotary cleaning body. The cleaning member 46b 46 scrapes off dust adhering to the filter net 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.

吸引口４７ａと共に回転清掃体４６が、エアフィルター２９の上端に達したら、自動で、吸引ノズル３０が、左方向に、回転清掃体４６の清掃部材４６ｂの長さと略等しい分だけ移動するように、ノズル移動手段３４が駆動する。そして、ローラ駆動手段４４が逆転し、帯状体４２を下降させながら、エアフィルター２９の上端から下端にかけて、塵埃を除去し、外部に排出する。   When the rotary cleaning body 46 together with the suction port 47a reaches the upper end of the air filter 29, the suction nozzle 30 automatically moves to the left by an amount substantially equal to the length of the cleaning member 46b of the rotary cleaning body 46. The nozzle moving means 34 is driven. Then, the roller driving means 44 reversely rotates and removes the dust from the upper end to the lower end of the air filter 29 while lowering the belt-like body 42, and discharges it to the outside.

このように、図６の矢印で示すように、帯状体４２と、吸引ノズル３０を順次移動させることにより、エアフィルター２９の全面を確実に清掃することができる。   Thus, as indicated by the arrows in FIG. 6, the entire surface of the air filter 29 can be reliably cleaned by sequentially moving the belt-like body 42 and the suction nozzle 30.

本実施例では、図６に示すように、回転清掃体４６が、エアフィルター２９の最上段の左端に達して、エアフィルター２９全面の清掃を終えるが、この後、次回のエアフィルター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. 6, 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 right end (initial position) of the lowermost stage of the air filter 29.

以上のように、本実施例によれば、エアフィルター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 this embodiment, the 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、回転清掃体４６を、帯状体４２の移動を駆動源として、すなわち、帯状体４２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 belt-like body 42 as a drive source, that is, with the movement of the belt-like body 42, 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.

また、空気調和機に内蔵されたエアフィルター２９が、図１、２に示すように湾曲していても、回転清掃体４６の回転中心軸が、吸引ノズル３０の長手方向と直交するように配しているので、帯状体４２の移動時に、回転清掃体４６を、エアフィルター２９の湾曲部にスムーズに沿わせることができ、エアフィルター２９の表面からの塵埃の除去漏れを防止することができる。   Even if the air filter 29 built in the air conditioner is curved as shown in FIGS. 1 and 2, the rotation center axis of the rotary cleaning body 46 is arranged so as to be orthogonal to the longitudinal direction of the suction nozzle 30. Therefore, when the belt-like body 42 is moved, the rotary cleaning body 46 can smoothly follow the curved portion of the air filter 29, and the removal of dust from the surface of the air filter 29 can be prevented. .

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ィルター（図示せず）を備えた空気調和機に搭載し、清掃装置２７で、エアフィ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。   Furthermore, 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 disposed on the upstream side of the heat exchanger. If the air filter is mounted on the air conditioner and 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.

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.
