Description

フィルタ保持装置、フィルタ清掃装置および空気調和機Filter holding device, filter cleaning device, and air conditioner
　本発明は、空気調和機等の吸込口に装着されるフィルタを保持するフィルタ保持装置、フィルタ清掃装置および空気調和機に関する。 The present invention relates to a filter holding device, a filter cleaning device, and an air conditioner that hold a filter attached to a suction port of an air conditioner or the like.
　空気調和機の室内機の吸込口に、フィルタが装着され、フィルタにより吸い込む空気から塵埃が除去される。最近では、このフィルタを移動させながら清掃するフィルタ清掃装置を搭載した空気調和機がある。フィルタ清掃装置は、フィルタを移動自在に保持するフィルタ保持装置を備えている。フィルタ保持装置は、キャビネットに設けられたフレームを有し、フレームに、着脱自在なフィルタが通る案内路が形成される。案内路を介してフィルタがキャビネットに保持される。そして、フィルタにラックが形成され、モータにより回転駆動されるピニオンがラックに噛み合う。ピニオンの回転により、フィルタが案内路を移動する。 ¡A filter is attached to the air inlet of the indoor unit of the air conditioner, and dust is removed from the air sucked by the filter. Recently, there is an air conditioner equipped with a filter cleaning device that cleans the filter while moving the filter. The filter cleaning device includes a filter holding device that holds the filter movably. The filter holding device has a frame provided in the cabinet, and a guide path through which the detachable filter passes is formed in the frame. The filter is held in the cabinet via the guide path. A rack is formed on the filter, and a pinion that is rotationally driven by the motor meshes with the rack. The filter moves along the guide path by the rotation of the pinion.
　ここで、フィルタは、洗浄や交換のために着脱可能とされている。例えば、特許文献１に記載の空気調和機では、案内路の一部を構成するガイド片が回動自在に設けられ、ガイド片を回動させると、ガイド片とともにフィルタが持ち上げる。キャビネットの前面にフィルタの挿入口が現れ、フィルタの着脱が容易に行える。 Here, the filter is removable for cleaning and replacement. For example, in the air conditioner described in Patent Document 1, a guide piece that constitutes a part of the guide path is rotatably provided, and when the guide piece is rotated, the filter is lifted together with the guide piece. A filter insertion slot appears on the front of the cabinet, making it easy to attach and detach the filter.

　ガイド片の回動に伴って、フィルタはピニオンから離れて持ち上がる。しかし、フィルタがピニオンに引っ掛かると、フィルタが持ち上がらない。ここで、フィルタを無理やり引っ張り出すと、ピニオンに負荷がかかって、ピニオンやその軸が損傷するおそれがある。 ¡The filter lifts away from the pinion as the guide piece rotates. However, when the filter is caught on the pinion, the filter does not lift up. Here, if the filter is forcibly pulled out, a load is applied to the pinion and the pinion and its shaft may be damaged.
　また、フィルタは、ガイド片に保持されて持ち上がる。このとき、ユーザは、ガイド片の挿入口からフィルタを取り出さなければならない。そのため、フィルタを簡単に着脱できるとは言い難い。 Also, the filter is lifted by being held by the guide piece. At this time, the user must take out the filter from the insertion opening of the guide piece. Therefore, it is difficult to say that the filter can be easily attached and detached.
　本発明は、上記に鑑み、フィルタだけを直接持ち上げることにより、フィルタを簡単に着脱できるフィルタ保持装置、フィルタ清掃装置および空気調和機の提供を目的とする。 In view of the above, an object of the present invention is to provide a filter holding device, a filter cleaning device, and an air conditioner that can be easily attached and detached by directly lifting only the filter.
本発明は、着脱可能なフィルタが通る案内路と、フィルタに接触してフィルタを案内路に沿って移動させる駆動体と、案内路から外れないようにフィルタをガイドするフィルタガイドとを備え、フィルタを駆動体から離す離間部材が設けられたフィルタ保持装置である。そして、フィルタガイドが案内路から離れるように移動したとき、離間部材は、フィルタを駆動体から離間させる。 The present invention includes a guide path through which a detachable filter passes, a driver that moves the filter along the guide path in contact with the filter, and a filter guide that guides the filter so that it does not come off the guide path. It is the filter holding | maintenance apparatus provided with the separation member which separates from a drive body. Then, when the filter guide moves away from the guide path, the separation member separates the filter from the drive body.
駆動体が駆動されると、駆動体に接触しているフィルタは案内路を移動する。フィルタを取り外す際に、駆動体が邪魔になる。そこで、フィルタを取り外すとき、まずフィルタガイドを案内路から離れるように移動させると、案内路が開放される。このフィルタガイドが移動することにより、離間部材がフィルタを駆動体から離れるように移動させる。フィルタが駆動体から離間することにより、フィルタは案内路から外れ、駆動体に引っ掛からずにフィルタを取り外すことができる。 When the driving body is driven, the filter in contact with the driving body moves in the guide path. When removing the filter, the driving body gets in the way. Therefore, when removing the filter, first, the guide guide is opened by moving the filter guide away from the guide guide. As the filter guide moves, the separating member moves the filter away from the driver. By separating the filter from the driving body, the filter is removed from the guide path, and the filter can be removed without being caught by the driving body.
フィルタガイドと離間部材とは、フィルタを挟んで対向して配置される。すなわち、フィルタガイドは、離間部材の移動を規制するものである。フィルタガイドが案内路から離れたとき、離間部材に対する規制が解除される。このように、離間部材を直接移動させる必要はなく、フィルタガイドを外すように移動させることによって、離間部材を移動可能とすることができる。 The filter guide and the separating member are disposed to face each other with the filter interposed therebetween. In other words, the filter guide regulates the movement of the separation member. When the filter guide is separated from the guide path, the restriction on the separation member is released. Thus, it is not necessary to move the separating member directly, and the separating member can be moved by moving the separating member so as to remove the filter guide.
フィルタガイドは、フィルタの表面側からフィルタを駆動体に押し付け、離間部材は、フィルタの裏面に当接して、フィルタを持ち上げる。フィルタガイドがフィルタを介して離間部材を押し付けることにより、離間部材の移動が規制される。フィルタガイドが案内路から離されたとき、フィルタガイドの規制がなくなるので、離間部材によりフィルタが持ち上げられる。 The filter guide presses the filter against the driving body from the front surface side of the filter, and the separating member comes into contact with the back surface of the filter to lift the filter. When the filter guide presses the separation member through the filter, the movement of the separation member is restricted. When the filter guide is separated from the guide path, the filter guide is not restricted, so that the filter is lifted by the separation member.
離間部材は、上下動可能に設けられ、弾性力を利用して離間部材は、上昇し、フィルタを持ち上げる。フィルタガイドがフィルタをガイドしているとき、言い換えれば、フィルタガイドが案内路の一部となる位置にあるとき、弾性力による離間部材の上昇が規制されている。フィルタガイドがフィルタから離れたとき、言い換えれば、フィルタガイドが案内路の一部を開放したとき、離間部材に対する規制が解除される。弾性力によって離間部材が自動的に上昇する。 The separation member is provided so as to be movable up and down, and the separation member rises and lifts the filter using elastic force. When the filter guide is guiding the filter, in other words, when the filter guide is at a position that becomes a part of the guide path, the rise of the separating member due to the elastic force is restricted. When the filter guide is separated from the filter, in other words, when the filter guide opens a part of the guide path, the restriction on the separating member is released. The spacing member is automatically raised by the elastic force.
フレームに案内路が形成され、フィルタはフレームの前後方向に移動し、フレームの左右方向に、複数の離間部材が上下動可能に設けられ、複数の離間部材が上昇することにより、フィルタが駆動体から離間される。複数の離間部材がフィルタを持ち上げることになり、左右方向においてフィルタを撓まないようにできる。そのため、フィルタを持ち上げるとき、フィルタを駆動体に引っ掛からないように離すことができる。 A guide path is formed in the frame, the filter moves in the front-rear direction of the frame, and a plurality of spacing members are provided in the left-right direction of the frame so as to be movable up and down. Spaced apart. A plurality of spacing members lift the filter, and the filter can be prevented from bending in the left-right direction. Therefore, when the filter is lifted, the filter can be separated so as not to be caught by the driving body.
複数の離間部材が連結されることにより、離間部材は一体化される。これによって、各離間部材は一体的に上下動可能となり、フィルタを一挙に撓まないように持ち上げることができる。 By connecting a plurality of spacing members, the spacing members are integrated. Thereby, each separation member can move up and down integrally, and the filter can be lifted so as not to be bent at once.
フィルタの左右方向の両端に、駆動体が接触し、離間部材は、左右方向の両側で駆動体の近傍に配置される。駆動体の近傍において、フィルタを持ち上げることができるので、例えフィルタが駆動体に引っ掛かるようなことがあっても、フィルタの駆動体に近い箇所に十分な力を加えることができ、フィルタを駆動体からスムーズに離すことが可能となる。 The drive body contacts both ends of the filter in the left-right direction, and the separating member is disposed in the vicinity of the drive body on both sides in the left-right direction. Since the filter can be lifted in the vicinity of the drive body, even if the filter is caught on the drive body, a sufficient force can be applied to a location close to the drive body of the filter, and the filter is connected to the drive body. Can be separated smoothly.
なお、フィルタ保持装置は、フィルタを案内路に沿って移動させながら、フィルタの清掃を行うフィルタ清掃装置に設けられる。空気調和機はフィルタ清掃装置を搭載する。フィルタ清掃装置は、フィルタから除去した塵埃を溜める着脱可能なダストボックスを備え、ダストボックスに、フィルタガイドが形成されている。ダストボックスを取り外すことによって、フィルタガイドが案内路から離れ、離間部材が連動して上昇し、フィルタが駆動体から離れる。 The filter holding device is provided in a filter cleaning device that cleans the filter while moving the filter along the guide path. The air conditioner is equipped with a filter cleaning device. The filter cleaning device includes a detachable dust box for storing dust removed from the filter, and a filter guide is formed in the dust box. By removing the dust box, the filter guide is separated from the guide path, the separating member is raised in conjunction with it, and the filter is separated from the driving body.
　本発明によると、ダストボックスのフィルタガイドを取り外す操作によって、フィルタを自動的にピニオン等の駆動体から離すことができる。したがって、フィルタを取り外すとき、駆動体に引っ掛かるようなことはなく、フィルタをスムーズに案内路から取り外すことができる。 According to the present invention, the filter can be automatically separated from the driving body such as the pinion by the operation of removing the filter guide of the dust box. Therefore, when removing the filter, the filter is not caught by the drive body, and the filter can be smoothly removed from the guide path.

　本実施形態の空気調和機の室内機を図１、２に示す。室内機は、熱交換器１および室内ファン２を備え、これらがキャビネット３に内装されている。キャビネット３の前面から底面にかけて湾曲面とされる。キャビネット３の上面に吸込口４が形成され、湾曲面に吹出口５が形成される。 1 and 2 show the indoor unit of the air conditioner of the present embodiment. The indoor unit includes a heat exchanger 1 and an indoor fan 2, which are housed in a cabinet 3. A curved surface is formed from the front surface to the bottom surface of the cabinet 3. A suction port 4 is formed on the upper surface of the cabinet 3, and an outlet 5 is formed on the curved surface.
　キャビネット３の内部には、吸込口４から吹出口５に至る空気通路６が形成され、この空気通路６に熱交換器１と室内ファン２とが配設される。吸込口４と熱交換器１との間に、フィルタ７が配され、吸込口４から吸込んだ室内の空気から塵埃を除去する。フィルタ７は左右２枚とされる。室内機には、このフィルタ７を移動させながら清掃するフィルタ清掃装置が設けられる。 An air passage 6 extending from the inlet 4 to the outlet 5 is formed inside the cabinet 3, and the heat exchanger 1 and the indoor fan 2 are disposed in the air passage 6. A filter 7 is disposed between the suction port 4 and the heat exchanger 1, and dust is removed from indoor air sucked from the suction port 4. There are two filters 7 on the left and right. The indoor unit is provided with a filter cleaning device that cleans the filter 7 while moving the filter 7.
　キャビネット３の湾曲面には、吹出口５を開閉するパネル１０が設けられる。パネル１０は、キャビネット３に開閉自在に支持され、パネル１０を開閉するための開閉部が設けられる。 A panel 10 for opening and closing the air outlet 5 is provided on the curved surface of the cabinet 3. The panel 10 is supported by the cabinet 3 so as to be openable and closable, and an opening and closing part for opening and closing the panel 10 is provided.
　空気調和機の運転時に、パネル１０が開く。冷房運転時には、パネル１０は、冷風を斜め上方向に導き、冷風が天井に沿って吹き出す。暖房運転時には、パネル１０は、前方に向かって吹き出される温風を押え込み、温風を床面方向に導く。なお、冷房運転の初期時にも、冷風が床面方向に吹き出され、急速冷房が行われる。パネル１０は、運転停止時には閉姿勢となり、吹出口５を覆って、キャビネット３と一体化する。 The panel 10 opens when the air conditioner is in operation. During the cooling operation, the panel 10 guides the cool air obliquely upward, and the cool air blows out along the ceiling. At the time of heating operation, the panel 10 presses the warm air blown forward and guides the warm air toward the floor surface. Even in the initial stage of the cooling operation, the cool air is blown out toward the floor surface, and rapid cooling is performed. The panel 10 is in a closed posture when the operation is stopped, covers the air outlet 5, and is integrated with the cabinet 3.
　また、キャビネット３内において、熱交換器１の下方にドレンパン１１が設けられ、熱交換器１を伝って流れ落ちてくる露を受ける。ドレンパン１１は、吹出口５を形成するドレンパンユニット１２に一体的に形成される。ドレンパンユニット１２には、イオンを発生するイオン発生ユニット１３が装着される。 In the cabinet 3, a drain pan 11 is provided below the heat exchanger 1 and receives dew that flows down through the heat exchanger 1. The drain pan 11 is integrally formed with the drain pan unit 12 that forms the air outlet 5. An ion generating unit 13 that generates ions is attached to the drain pan unit 12.
　空気調和機では、室内機に対して図示しない室外機が室外に設置されている。室外機には、圧縮機、熱交換器、四方弁、室外ファン等が内装され、これらと室内側の熱交換器１とによって冷凍サイクルが形成される。そして、冷凍サイクルを制御する制御装置が室内機に設けられる。マイコンからなる制御装置は、ユーザの指示および室温や外気温を検出する温度センサ等の各種のセンサの検出信号に基づいて、冷凍サイクルを制御し、冷暖房運転を行う。このとき、制御装置は、冷暖房運転に応じて開閉部を制御し、パネル１０を開閉する。また、制御装置は、定期的にあるいはユーザからの指示により、フィルタ清掃装置を制御して、フィルタ７を移動させながら清掃する。 In the air conditioner, an outdoor unit (not shown) is installed outside the indoor unit. The outdoor unit includes a compressor, a heat exchanger, a four-way valve, an outdoor fan, and the like, and these and the indoor heat exchanger 1 form a refrigeration cycle. And the control apparatus which controls a refrigerating cycle is provided in an indoor unit. A control device including a microcomputer controls the refrigeration cycle based on a user instruction and detection signals of various sensors such as a temperature sensor that detects a room temperature and an outside temperature, and performs an air conditioning operation. At this time, the control device controls the opening / closing unit according to the cooling / heating operation to open / close the panel 10. Further, the control device controls the filter cleaning device periodically or in accordance with an instruction from the user to clean the filter 7 while moving it.
　フィルタ清掃装置は、フィルタ７を移動させる移動部１５と、フィルタ７を清掃する清掃部１６と、フィルタ７から除去された塵埃を収容するダストボックス１７とを備え、これらが、図３に示すように、ユニットフレーム１８に一体的に設けられる。フィルタ７は、ユニットフレーム１８に保持され、フィルタ７が移動するときには、フィルタ７はユニットフレーム１８によりガイドされる。このユニットフレーム１８により、着脱可能なフィルタ７を移動可能に保持するフィルタ保持装置が構成される。すなわち、フィルタ清掃装置は、フィルタ保持装置を有するものである。 The filter cleaning apparatus includes a moving unit 15 that moves the filter 7, a cleaning unit 16 that cleans the filter 7, and a dust box 17 that accommodates dust removed from the filter 7, and these are as shown in FIG. The unit frame 18 is integrally provided. The filter 7 is held by the unit frame 18, and the filter 7 is guided by the unit frame 18 when the filter 7 moves. The unit frame 18 constitutes a filter holding device that holds the removable filter 7 so as to be movable. That is, the filter cleaning device has a filter holding device.
　ユニットフレーム１８は、熱交換器１の前面から上面までを覆うように、キャビネット３に取り付けられ、キャビネット３に対して着脱可能とされる。ユニットフレーム１８の前方に、開閉可能な前面パネル１９が設けられる。前面パネル１９は、キャビネット３に着脱可能に取り付けられる。前面パネル１９は、キャビネット３の上部の軸周りに開閉し、前面パネル１９が開いたとき、ダストボックス１７が現れる。ダストボックス１７は、ユニットフレーム１８に着脱可能に装着されている。ダストボックス１７を取り外したとき、フィルタ７の着脱が可能となる。 The unit frame 18 is attached to the cabinet 3 so as to cover from the front surface to the upper surface of the heat exchanger 1, and is detachable from the cabinet 3. A front panel 19 that can be opened and closed is provided in front of the unit frame 18. The front panel 19 is detachably attached to the cabinet 3. The front panel 19 opens and closes around the upper axis of the cabinet 3, and when the front panel 19 is opened, the dust box 17 appears. The dust box 17 is detachably attached to the unit frame 18. When the dust box 17 is removed, the filter 7 can be attached and detached.
　フィルタ７は、図４に示すように、メッシュ部２０と、メッシュ部２０の周囲を取り囲む枠体２１とから構成される。そして、メッシュ部２０と枠体２１とがポリプロピレン樹脂等の合成樹脂により一体的に成形され、枠体２１は前後対称かつ左右対称な形状とされる。また、メッシュ部２０の形状も前後対称かつ左右対称とされる。したがって、前後左右対称なフィルタ７は、前後のいずれの方向からでもキャビネット３に装着可能とされる。 As shown in FIG. 4, the filter 7 includes a mesh portion 20 and a frame body 21 surrounding the mesh portion 20. And the mesh part 20 and the frame 21 are integrally shape | molded by synthetic resins, such as a polypropylene resin, and the frame 21 is made into the back-and-front symmetrical and left-right symmetric shape. The shape of the mesh part 20 is also symmetric in the front-rear direction and in the left-right direction. Therefore, the front-rear and left-right symmetric filter 7 can be mounted on the cabinet 3 from either front or rear direction.
　枠体２１は、左右に位置する縦枠２１ａと前後に位置する横枠２１ｂとから四角形の枠状に形成される。メッシュ部２０の裏面に、補強のために縦リブ２２ａおよび横リブ２２ｂがそれぞれ等間隔に形成されている。メッシュ部２０の表面は、面一とされる。 The frame body 21 is formed in a rectangular frame shape from a vertical frame 21a positioned on the left and right and a horizontal frame 21b positioned on the front and rear. On the back surface of the mesh part 20, vertical ribs 22a and horizontal ribs 22b are formed at equal intervals for reinforcement. The surface of the mesh part 20 is flush.
　縦枠２１ａに、移動部１５の回転駆動されるピニオンに噛み合うラック２４が形成される。ラック２４は、フィルタ７の裏面側に凸、表面側では凹となるように形成される。また、ラック２４は、縦枠２１ａの前端から後端にかけて形成され、前後いずれの方向からユニットフレーム１８に装着されても、ピニオンに噛み合うようになっている。ラック２４の凸部分の高さは、縦リブ２２ａよりも高く、横リブ２２ｂの高さ以上とされる。縦枠２１ａおよび縦リブ２２ａは、横枠２１ｂおよび横リブ２２ｂよりも薄肉とされる。これにより、フィルタ７は、横方向の剛性を維持しながら、縦方向には可撓性を有し、フィルタ７を縦方向に屈曲させることができる。 In the vertical frame 21a, a rack 24 is formed that meshes with a pinion that is rotationally driven by the moving unit 15. The rack 24 is formed to be convex on the back side of the filter 7 and concave on the front side. The rack 24 is formed from the front end to the rear end of the vertical frame 21a, and engages with the pinion regardless of whether the rack 24 is attached to the unit frame 18 from the front or rear direction. The height of the convex portion of the rack 24 is higher than that of the vertical rib 22a and is equal to or higher than the height of the horizontal rib 22b. The vertical frame 21a and the vertical rib 22a are thinner than the horizontal frame 21b and the horizontal rib 22b. Thereby, the filter 7 has flexibility in the vertical direction while maintaining the rigidity in the horizontal direction, and the filter 7 can be bent in the vertical direction.
　四角形のフィルタ７の４隅が斜めに切り欠かれ、傾斜面２５が形成される。傾斜面２５は、縦方向に長く切り欠かれ、横方向には短く切り欠かれることによって形成される。なお、各隅の傾斜面２５は同じ形状である。 Four corners of the square filter 7 are cut obliquely to form an inclined surface 25. The inclined surface 25 is formed by being cut long in the vertical direction and short in the horizontal direction. The inclined surface 25 at each corner has the same shape.
　フィルタ７は、表面を上にして、前側あるいは後側のいずれかの方向から装着される。そのため、横枠２１ｂには、表裏と挿入方向を示すマーク２６が設けられている。前後の横枠２１ｂの表面に、「オモテ」と「挿入方向」といったマーク２６が成形あるいは刻印により形成される。横枠２１ｂの裏面には、「ウラ」といったマーク２７が成形あるいは刻印により形成される。これによって、ユーザは、フィルタ７の表裏を間違えることなく、容易にキャビネット３にフィルタ７を挿入して装着することができる。なお、マークとして、上記のような語句に限らず、記号、絵を用いてもよい。 The filter 7 is mounted from either the front side or the rear side with the surface facing up. Therefore, the horizontal frame 21b is provided with a mark 26 indicating the front and back and the insertion direction. Marks 26 such as “front” and “insertion direction” are formed on the surface of the front and rear horizontal frames 21b by molding or stamping. A mark 27 such as “back” is formed on the back surface of the horizontal frame 21b by molding or stamping. Thus, the user can easily insert and attach the filter 7 to the cabinet 3 without making a mistake in the front and back of the filter 7. Note that the mark is not limited to the above words and phrases, and a symbol or a picture may be used.
　ユニットフレーム１８は、図５～８に示すように、フィルタ７を保持するベース板３０と、左右の側枠３１とから形成される。ベース板３０は、上面から前面にかけて湾曲し、平坦な下面を有する。ベース板３０の左右両端に側枠３１が一体的に立設される。ベース板３０の湾曲部分は開口しており、ベース板３０の左右方向の中央に、センタ枠３２が設けられ、開口が２分割される。この開口に、縦横の桟３３によって格子部３４が形成される。格子部３４は、熱交換器１に対向する位置にあり、フィルタ７を通過した空気が熱交換器１に向かって格子部３４を通り抜ける。 The unit frame 18 is formed of a base plate 30 that holds the filter 7 and left and right side frames 31 as shown in FIGS. The base plate 30 is curved from the upper surface to the front surface and has a flat lower surface. Side frames 31 are erected integrally at both left and right ends of the base plate 30. The curved portion of the base plate 30 is open, and a center frame 32 is provided in the center of the base plate 30 in the left-right direction, and the opening is divided into two. A lattice portion 34 is formed by vertical and horizontal bars 33 in the opening. The lattice part 34 is in a position facing the heat exchanger 1, and the air that has passed through the filter 7 passes through the lattice part 34 toward the heat exchanger 1.
　ユニットフレーム１８に、移動するフィルタ７をガイドする案内路３５が形成される。図７に示すように、清掃時に、フィルタ７は、吸込口４と熱交換器１との間に装着された装着位置から下に向かって移動し、Ｕターンして、格子部３４に沿って移動し、吸込口４と熱交換器１との間に達する。ユニットフレーム１８の左右の側枠３１およびセンタ枠３２に、側面から見てσ形状のガイド溝３６が形成され、ガイド溝３６に、フィルタ７の縦枠２１ａがスライド可能に嵌り込む。このガイド溝３６およびベース板３０の格子部３４によって、フィルタ７がＵターンするように移動するための案内路３５が、ユニットフレーム１８の前面から上面にかけての空間に形成される。 A guide path 35 for guiding the moving filter 7 is formed in the unit frame 18. As shown in FIG. 7, during cleaning, the filter 7 moves downward from the mounting position mounted between the suction port 4 and the heat exchanger 1, makes a U-turn, and moves along the lattice portion 34. It moves and reaches between the inlet 4 and the heat exchanger 1. Σ-shaped guide grooves 36 are formed in the left and right side frames 31 and the center frame 32 of the unit frame 18 when viewed from the side, and the vertical frame 21a of the filter 7 is slidably fitted into the guide grooves 36. A guide path 35 for moving the filter 7 to make a U-turn is formed in a space from the front surface to the upper surface of the unit frame 18 by the guide groove 36 and the lattice portion 34 of the base plate 30.
　移動部１５は、フィルタ７のラック２４に噛み合うピニオン４０と、ピニオン４０を回転駆動するステッピングモータ４１と、フィルタ７の移動を補助するガイドローラ４２とを有する。ピニオン４０が、フィルタ７に接触してフィルタ７を案内路３５に沿って移動させる駆動体とされる。 The moving unit 15 includes a pinion 40 that meshes with the rack 24 of the filter 7, a stepping motor 41 that rotationally drives the pinion 40, and a guide roller 42 that assists the movement of the filter 7. The pinion 40 is a driving body that contacts the filter 7 and moves the filter 7 along the guide path 35.
　ユニットフレーム１８の側枠３１の外面側にステッピングモータ４１が取り付けられ、側枠３１の内面側にピニオン４０が回転可能に支持される。センタ枠３２にも、ピニオン４０が回転可能に支持される。ステッピングモータ４１のモータ軸に取り付けられたギアを介してピニオン４０に回転駆動力が伝達される。左右のピニオン４０は、回転軸４３によって連結される。回転軸４３に、ガイドローラ４２が取り付けられる。ピニオン４０の回転に連動して、ガイドローラ４２も回転する。なお、移動部１５は、左右のフィルタ７に対応して、左右一対に設けられる。２つのステッピングモータ４１は同期して駆動される。ガイドローラ４２の材質は樹脂からなる。なお、ガイドローラ４２の材質はゴムであってもよく、あるいは樹脂製の芯にゴムを巻き付けたものであってもよい。 The stepping motor 41 is attached to the outer surface side of the side frame 31 of the unit frame 18, and the pinion 40 is rotatably supported on the inner surface side of the side frame 31. A pinion 40 is also rotatably supported by the center frame 32. A rotational driving force is transmitted to the pinion 40 via a gear attached to the motor shaft of the stepping motor 41. The left and right pinions 40 are connected by a rotation shaft 43. A guide roller 42 is attached to the rotation shaft 43. In conjunction with the rotation of the pinion 40, the guide roller 42 also rotates. The moving unit 15 is provided in a pair of left and right corresponding to the left and right filters 7. The two stepping motors 41 are driven in synchronization. The material of the guide roller 42 is made of resin. The material of the guide roller 42 may be rubber, or may be one in which rubber is wound around a resin core.
　図３，８に示すように、ベース板３０の下面に、ダストボックス１７が装着される。ダストボックス１７は、左右にそれぞれ設けられる。ダストボックス１７は、フィルタ７から除去された塵埃を溜める集塵箱４５、屈曲しながら移動するフィルタ７を押えるフィルタガイド４６、フィルタ７の移動をガイドするガイドリブ４７を備え、これらが一体化されている。 3 and 8, the dust box 17 is attached to the lower surface of the base plate 30. The dust boxes 17 are provided on the left and right, respectively. The dust box 17 includes a dust collection box 45 for collecting dust removed from the filter 7, a filter guide 46 for pressing the filter 7 that moves while being bent, and a guide rib 47 for guiding the movement of the filter 7, and these are integrated. .
　集塵箱４５は、ガイドローラ４２の下方に配置される。集塵箱４５の前側の上部に、フィルタガイド４６が設けられ、フィルタガイド４６は、ガイドローラ４２の前方に位置する。フィルタガイド４６のフィルタ７に対向する後面側に、補助ガイドリブ４８が形成される。複数の補助ガイドリブ４８が、左右方向に間隔をおいて配置される。 The dust collection box 45 is disposed below the guide roller 42. A filter guide 46 is provided in the upper part on the front side of the dust collection box 45, and the filter guide 46 is positioned in front of the guide roller 42. An auxiliary guide rib 48 is formed on the rear side of the filter guide 46 facing the filter 7. A plurality of auxiliary guide ribs 48 are arranged at intervals in the left-right direction.
　ガイドリブ４７は、集塵箱４５の後側の上部に設けられ、集塵箱４５に回動可能に支持される。複数のガイドリブ４７が、左右方向に間隔をおいて配置され、各ガイドリブ４７は一体的に形成される。ガイドリブ４７および補助ガイドリブ４８は、案内路３５を移動するフィルタ７の縦枠２１ａおよび縦リブ２２ａの位置に対応するように配置される。これにより、ガイドリブ４７および補助ガイドリブ４８は、フィルタ７の縦枠２１ａおよび縦リブ２２ａに接触し、フィルタ７を通過する空気の流れを邪魔しない。 The guide rib 47 is provided at the upper part on the rear side of the dust collection box 45 and is rotatably supported by the dust collection box 45. A plurality of guide ribs 47 are arranged at intervals in the left-right direction, and each guide rib 47 is integrally formed. The guide rib 47 and the auxiliary guide rib 48 are arranged so as to correspond to the positions of the vertical frame 21 a and the vertical rib 22 a of the filter 7 that moves in the guide path 35. Thereby, the guide rib 47 and the auxiliary guide rib 48 are in contact with the vertical frame 21a and the vertical rib 22a of the filter 7 and do not disturb the flow of air passing through the filter 7.
　ガイドリブ４７が閉じたとき、集塵箱４５の上部に載る。このとき、ガイドリブ４７は、フィルタガイド４６の補助ガイドリブ４８と組み合わされる。さらに、ガイドリブ４７は、ベース板３０の下面に形成された補助ガイドリブ４９とも組み合わされる。これらのリブの組み合わせによって、ガイドローラ４２の半周以上を取り囲む一連のガイドリブが形成され、案内路３５の一部を形成する。このように、フィルタガイド４６およびガイドリブ４７は、移動するフィルタ７が案内路３５から外れないようにガイドする。 When the guide rib 47 is closed, it is placed on the upper part of the dust collection box 45. At this time, the guide rib 47 is combined with the auxiliary guide rib 48 of the filter guide 46. Further, the guide rib 47 is also combined with an auxiliary guide rib 49 formed on the lower surface of the base plate 30. A combination of these ribs forms a series of guide ribs that surround more than half a circumference of the guide roller 42, and forms a part of the guide path 35. Thus, the filter guide 46 and the guide rib 47 guide the moving filter 7 so that it does not come off the guide path 35.
　清掃部１６は、フィルタ７に接触して、塵埃を掻き取る回転ブラシ５０と、回転ブラシ５０を回転駆動する清掃モータ５１とを有する。回転ブラシ５０は、ガイドローラ４２の下側に接するように配される。そして、回転ブラシ５０は、ダストボックス１７に回転可能に支持される。すなわち、回転ブラシ５０の支軸５２の両側に、支軸５２を回転可能に支持するハブが取り付けられ、ハブが集塵箱４５の上部に形成されたＵ字状の軸受に載置される。閉じた状態のガイドリブ４７がハブを押え込む。支軸５２のハブが軸受とガイドリブ４７とにより挟み込まれることにより、回転ブラシ５０はダストボックス１７に回転可能に支持される。 The cleaning unit 16 includes a rotating brush 50 that contacts the filter 7 and scrapes off dust, and a cleaning motor 51 that rotationally drives the rotating brush 50. The rotating brush 50 is disposed so as to contact the lower side of the guide roller 42. The rotating brush 50 is rotatably supported by the dust box 17. That is, hubs that rotatably support the support shaft 52 are attached to both sides of the support shaft 52 of the rotating brush 50, and the hub is placed on a U-shaped bearing formed on the upper portion of the dust collection box 45. The closed guide rib 47 presses the hub. When the hub of the support shaft 52 is sandwiched between the bearing and the guide rib 47, the rotating brush 50 is rotatably supported by the dust box 17.
　回転ブラシ５０の支軸５２は、集塵箱４５の左右両側から外側に突出しており、支軸５２の両端にギアが取り付けられている。ユニットフレーム１８の側枠３１の外側に、清掃モータ５１が取り付けられ、清掃モータ５１のモータ軸に取り付けられたギアが支軸５２のギアに噛み合う。また、センタ枠３２に、中間ギアが設けられ、左右のダストボックス１７のセンタ枠側にあるギアが中間ギアと噛み合う。清掃モータ５１は、左右方向における電装ボックスが配置された一側に設置される。清掃モータ５１が駆動されると、一側の回転ブラシ５０が回転し、この回転駆動力が中間ギアを介して他側の支軸５２に伝達され、両側の回転ブラシ５０が連動して回転する。 The support shaft 52 of the rotating brush 50 protrudes outward from the left and right sides of the dust collection box 45, and gears are attached to both ends of the support shaft 52. The cleaning motor 51 is attached to the outside of the side frame 31 of the unit frame 18, and the gear attached to the motor shaft of the cleaning motor 51 meshes with the gear of the support shaft 52. The center frame 32 is provided with an intermediate gear, and the gears on the center frame side of the left and right dust boxes 17 mesh with the intermediate gear. The cleaning motor 51 is installed on one side where the electrical box in the left-right direction is disposed. When the cleaning motor 51 is driven, the rotary brush 50 on one side rotates, and this rotational driving force is transmitted to the other support shaft 52 via the intermediate gear, and the rotary brushes 50 on both sides rotate in conjunction with each other. .
　ダストボックス１７は、ユニットフレーム１８に対して着脱可能とされる。ベース板３０の下面に、フック５３が突設される。フック５３は、左右方向の中央に位置する。集塵箱４５の底面の中央に、凹み５４が形成される。この凹み５４にフック５３が嵌り込む。フィルタガイド４６の前面に、ロックバーをスライドさせるスライドレバー５５が左右一対に設けられる。ユーザによるスライドレバー５５のスライド操作により、ロックバーが外側に向かって突出すると、側枠３１に形成された孔にロックバーが嵌る。 The dust box 17 can be attached to and detached from the unit frame 18. A hook 53 projects from the lower surface of the base plate 30. The hook 53 is located at the center in the left-right direction. A recess 54 is formed in the center of the bottom surface of the dust collection box 45. A hook 53 is fitted into the recess 54. A pair of left and right slide levers 55 for sliding the lock bar are provided on the front surface of the filter guide 46. When the lock bar protrudes outward by the slide operation of the slide lever 55 by the user, the lock bar fits into the hole formed in the side frame 31.
　また、集塵箱４５の左右の側面にピン５６が突設される。側枠３１に、Ｕ字状に凹んだ位置決め部５７が形成される。ピン５６が位置決め部５７に嵌まり込むことにより、ダストボックス１７がユニットフレーム１８に対して位置決めされる。このようにして、ダストボックス１７は、ユニットフレーム１８の定位置に装着される。ダストボックス１７を取り外すときには、ユーザは、ロックバーを引っ込めるように操作して、ダストボックス１７を持ち上げる。なお、ピン５６は、フィルタガイド４６の左右の側面に設けてもよい。 Also, pins 56 are provided on the left and right side surfaces of the dust collection box 45 in a protruding manner. A positioning portion 57 that is recessed in a U shape is formed on the side frame 31. When the pin 56 is fitted into the positioning portion 57, the dust box 17 is positioned with respect to the unit frame 18. In this way, the dust box 17 is mounted at a fixed position of the unit frame 18. When removing the dust box 17, the user operates to retract the lock bar and lifts the dust box 17. The pins 56 may be provided on the left and right side surfaces of the filter guide 46.
　図８（ｂ）に示すように、ダストボックス１７がキャビネット３から取り外されると、案内路３５の一部が開放され、フィルタ７をキャビネット３に対して出し入れするための挿入口５８が現れる。この挿入口５８を通じて、ユーザはフィルタ７を着脱することができる。ここで、フィルタ７を取り外しやすくするために、フィルタ７をピニオン４０から離す離間部材が設けられている。 As shown in FIG. 8B, when the dust box 17 is removed from the cabinet 3, a part of the guide path 35 is opened, and an insertion port 58 for taking the filter 7 in and out of the cabinet 3 appears. The user can attach and detach the filter 7 through the insertion port 58. Here, in order to make it easy to remove the filter 7, a separating member for separating the filter 7 from the pinion 40 is provided.
　離間部材は、フィルタ７を持ち上げるリフトアップ部材６０とされ、リフトアップ部材６０は、ユニットフレーム１８に上下動可能に設けられる。リフトアップ部材６０は、フィルタ７の裏面（熱交換器１と対向する側の面）に当接するように、案内路３５に対してピニオン４０よりも内側に位置するように配置される。すなわち、Ｕターンする案内路３５に囲まれた空間に、リフトアップ部材６０が配置され、案内路３５を移動するフィルタ７の邪魔にならない。ダストボックス１７が取り外されたときに、このダストボックス１７の動きに連動してリフトアップ部材６０が、案内路３５の外側に突出するように上昇する。これにより、リフトアップ部材６０は、フィルタ７を持ち上げ、ピニオン４０およびガイドローラ４２からフィルタ７を離間させる。 The separating member is a lift-up member 60 that lifts the filter 7, and the lift-up member 60 is provided on the unit frame 18 so as to be movable up and down. The lift-up member 60 is disposed so as to be located on the inner side of the pinion 40 with respect to the guide path 35 so as to contact the back surface of the filter 7 (the surface on the side facing the heat exchanger 1). That is, the lift-up member 60 is arranged in a space surrounded by the guide path 35 that makes a U-turn, and does not interfere with the filter 7 that moves along the guide path 35. When the dust box 17 is removed, the lift-up member 60 rises so as to protrude outside the guide path 35 in conjunction with the movement of the dust box 17. Accordingly, the lift-up member 60 lifts the filter 7 and separates the filter 7 from the pinion 40 and the guide roller 42.
　リフトアップ部材６０は、フィルタ７の縦枠２１ａに対向して配置され、左右一対に設けられる。すなわち、リフトアップ部材６０とフィルタガイド４６とは、フィルタ７を挟んで対向して配置される。一側のリフトアップ部材６０の後側が側枠３１に回動可能に支持され、他側のリフトアップ部材６０の後側がセンタ枠３２に回動可能に支持される。リフトアップ部材６０は、ピニオン４０とガイドローラ４２との間に位置し、フィルタ７の縦枠２１ａの裏面に当接する。 The lift-up member 60 is disposed to face the vertical frame 21a of the filter 7, and is provided in a pair of left and right. That is, the lift-up member 60 and the filter guide 46 are disposed to face each other with the filter 7 interposed therebetween. The rear side of the lift-up member 60 on one side is rotatably supported by the side frame 31, and the rear side of the lift-up member 60 on the other side is rotatably supported by the center frame 32. The lift-up member 60 is located between the pinion 40 and the guide roller 42 and abuts on the back surface of the vertical frame 21 a of the filter 7.
　リフトアップ部材６０は、リフトアップ部材６０の後側を中心にして前端が上下動する。左右のリフトアップ部材６０が上方向に回動するように、リフトアップ部材６０を上方向に付勢する付勢部材が設けられる。付勢部材として、ばね６１が用いられる。リフトアップ部材６０の下側にばね６１が配置され、ばね６１は、側枠３１あるいはセンタ枠３２に保持される。左右のリフトアップ部材６０の後側が水平な連結材６２によって連結されている。これにより、両側のリフトアップ部材６０が一体化され、同時に上下動する。 The front end of the lift-up member 60 moves up and down around the rear side of the lift-up member 60. A biasing member that biases the lift-up member 60 upward is provided so that the left and right lift-up members 60 rotate upward. A spring 61 is used as the biasing member. A spring 61 is disposed below the lift-up member 60, and the spring 61 is held by the side frame 31 or the center frame 32. The rear sides of the left and right lift-up members 60 are connected by a horizontal connecting member 62. As a result, the lift-up members 60 on both sides are integrated and moved up and down simultaneously.
　リフトアップ部材６０は、ばね６１の弾性力を利用して上昇する。リフトアップ部材６０には、ばね６１の弾性力が常に作用している。ばね６１によって回動したリフトアップ部材６０は、フィルタ７の左右の縦枠２１ａに当接して、フィルタ７を押し上げる。ダストボックス１７が装着されているとき、フィルタガイド４６の補助ガイドリブ４８は、フィルタ７を押えているので、ばね６１の弾性力がリフトアップ部材６０に作用しても、フィルタ７が持ち上がることはない。すなわち、フィルタガイド４６は、フィルタ７を介してリフトアップ部材６０を押えて、リフトアップ部材６０の移動を規制する。 The lift-up member 60 is lifted using the elastic force of the spring 61. The lift-up member 60 is always subjected to the elastic force of the spring 61. The lift-up member 60 rotated by the spring 61 abuts on the left and right vertical frames 21 a of the filter 7 and pushes up the filter 7. Since the auxiliary guide rib 48 of the filter guide 46 presses the filter 7 when the dust box 17 is mounted, the filter 7 will not be lifted even if the elastic force of the spring 61 acts on the lift-up member 60. That is, the filter guide 46 presses the lift-up member 60 through the filter 7 and restricts the movement of the lift-up member 60.
　ダストボックス１７が取り外されると、フィルタガイド４６の補助ガイドリブ４８は、案内路３５から離れ、フィルタガイド４６による押えがなくなる。すなわち、リフトアップ部材６０に対する移動の規制が解除され、ばね６１の弾性力による作用が発揮され、リフトアップ部材６０が上昇する。このようなフィルタガイド４６の移動に追従して、ばね６１の弾性力によりリフトアップ部材６０が、自動的に前方の斜め上に向かって上昇する。 When the dust box 17 is removed, the auxiliary guide ribs 48 of the filter guide 46 are separated from the guide path 35 and are not pressed by the filter guide 46. That is, the restriction | limiting of the movement with respect to the lift-up member 60 is cancelled | released, the effect | action by the elastic force of the spring 61 is exhibited, and the lift-up member 60 raises. Following the movement of the filter guide 46 as described above, the lift-up member 60 is automatically raised upward and obliquely upward by the elastic force of the spring 61.
　リフトアップ部材６０はピニオン４０の近傍に配置されているので、リフトアップ部材６０は直接フィルタ７をピニオン４０から引き離すように作用する。そのため、フィルタ７のラック２４がピニオン４０に引っ掛かっても、フィルタ７を持ち上げることができ、ラック２４からピニオン４０を引き抜くことができる。また、フィルタ７の左右両側が持ち上げられるので、ピニオン４０に対してフィルタ７は撓まないように上昇する。そのため、フィルタ７のラック２４からピニオン４０がスムーズに抜け、フィルタ７はピニオン４０に引っ掛からない。 Since the lift-up member 60 is disposed in the vicinity of the pinion 40, the lift-up member 60 directly acts to separate the filter 7 from the pinion 40. Therefore, even if the rack 24 of the filter 7 is caught by the pinion 40, the filter 7 can be lifted and the pinion 40 can be pulled out from the rack 24. Moreover, since both the left and right sides of the filter 7 are lifted, the filter 7 rises so as not to bend with respect to the pinion 40. Therefore, the pinion 40 is smoothly removed from the rack 24 of the filter 7, and the filter 7 is not caught by the pinion 40.
　このようにして、フィルタ７の前側が持ち上げられ、フィルタ７はピニオン４０およびガイドローラ４２から離れる。したがって、ユーザは、フィルタ７を掴んで挿入口５８からスムーズに引き出すことができる。フィルタ７が引き出されるとき、フィルタ７がピニオン４０に引っ掛かることはない。 In this way, the front side of the filter 7 is lifted, and the filter 7 is separated from the pinion 40 and the guide roller 42. Therefore, the user can grasp the filter 7 and smoothly pull it out from the insertion port 58. When the filter 7 is pulled out, the filter 7 is not caught on the pinion 40.
　リフトアップ部材６０は、上がり過ぎないように規制されている。図６、９に示すように、リフトアップ部材６０に係止爪６３が設けられる。係止爪６３は、リフトアップ部材６０から下側に向かって突出している。側枠３１あるいはセンタ枠３２にストッパ６４が形成され、ストッパ６４に係止爪６３が引っ掛かることにより、リフトアップ部材６０の上昇が規制される。なお、リフトアップ部材６０の最大上昇位置は、ピニオン４０の歯先よりも高く上がるように、係止爪６３の長さによって設定される。 The lift-up member 60 is regulated so as not to rise too much. As shown in FIGS. 6 and 9, the claw 63 is provided on the lift-up member 60. The locking claw 63 protrudes downward from the lift-up member 60. A stopper 64 is formed on the side frame 31 or the center frame 32, and when the locking claw 63 is hooked on the stopper 64, the lift of the lift-up member 60 is restricted. The maximum lift position of the lift-up member 60 is set by the length of the locking claw 63 so as to rise higher than the tooth tip of the pinion 40.
　このように、リフトアップ部材６０の上がり過ぎを防止することにより、リフトアップ部材６０が挿入口５８の一部を塞いでしまうことを防ぎ、リフトアップ部材６０はフィルタ７の装着の邪魔にならない。しかも、ユーザがフィルタ７を取り出す際、フィルタ７がピニオン４０やガイドローラ４２に触れないように、フィルタ７を引っ張り出すことができる。そのため、フィルタ７に衝撃を与えることなく、フィルタ７を引き出すことができ、フィルタ７に塵埃が付着していても、塵埃は落下しない。したがって、ユーザの手や周囲を汚すことを防止できる。また、リフトアップ部材６０は、フィルタ７の左右の縦枠２１ａに当接して、フィルタ７を押し上げる。ここで、リフトアップ部材６０は縦枠２１ａに完全に対向していなくてもよく、リフトアップ部材６０の一部がメッシュ部２０に当接して、メッシュ部２０を押し上げるようにしてもよい。 Thus, by preventing the lift-up member 60 from being raised too much, the lift-up member 60 is prevented from blocking a part of the insertion port 58, and the lift-up member 60 does not interfere with the mounting of the filter 7. In addition, when the user takes out the filter 7, the filter 7 can be pulled out so that the filter 7 does not touch the pinion 40 or the guide roller 42. Therefore, the filter 7 can be pulled out without giving an impact to the filter 7, and even if dust adheres to the filter 7, the dust does not fall. Therefore, it is possible to prevent the user's hand and surroundings from being soiled. Further, the lift-up member 60 abuts on the left and right vertical frames 21 a of the filter 7 and pushes up the filter 7. Here, the lift-up member 60 may not completely face the vertical frame 21a, and a part of the lift-up member 60 may abut against the mesh portion 20 to push up the mesh portion 20.
　フィルタ７を装着するとき、挿入口５８では、側枠３１のガイド溝３６が外部から見える。ユーザは、フィルタ７の縦枠２１ａを側枠３１のガイド溝３６に挿入する。このとき、ユーザは、フィルタ７の前後方向および表裏面を確認する。左右にラック２４が形成されているので、フィルタ７の前後方向を容易に確認できる。フィルタ７の前側と後側を確認する必要はない。また、表裏面を示すマーク２６、２７があり、表裏面の形状が異なるので、表裏面も容易に確認できる。したがって、ユーザは、フィルタ７を一目見て、フィルタ７の挿入する方向を認識でき、フィルタ７の装着作業が容易となる。また、フィルタ７をキャビネット３の前面から装着する場合だけでなく、上面あるいは底面から装着するような場合であっても、容易にフィルタ７を装着できる。 When the filter 7 is mounted, the guide groove 36 of the side frame 31 can be seen from the outside at the insertion port 58. The user inserts the vertical frame 21 a of the filter 7 into the guide groove 36 of the side frame 31. At this time, the user confirms the front-rear direction and the front and back surfaces of the filter 7. Since the racks 24 are formed on the left and right, the front-rear direction of the filter 7 can be easily confirmed. There is no need to check the front side and the rear side of the filter 7. Moreover, there are marks 26 and 27 indicating the front and back surfaces, and the shapes of the front and back surfaces are different, so the front and back surfaces can be easily confirmed. Therefore, the user can recognize the insertion direction of the filter 7 at a glance and can easily attach the filter 7. Further, the filter 7 can be easily mounted not only when the filter 7 is mounted from the front surface of the cabinet 3 but also when the filter 7 is mounted from the top surface or the bottom surface.
　ユーザは、フィルタ７を案内路３５に挿入する。フィルタ７が案内路３５の後側まで挿入されたとき、フィルタ７の前側は、ピニオン４０から浮かび上がっている。その後、ユーザがダストボックス１７を装着すると、フィルタ７の前側がダストボックス１７のフィルタガイド４６に押えられる。フィルタ７が押し込まれるのに伴って、リフトアップ部材６０は、フィルタ７の縦枠２１ａの裏面に接触しながら押し下げられる。このとき、縦枠２１ａのラック２４がピニオン４０に噛み合う。フィルタ７は、装着位置に装着される。 The user inserts the filter 7 into the guide path 35. When the filter 7 is inserted to the rear side of the guide path 35, the front side of the filter 7 is raised from the pinion 40. Thereafter, when the user attaches the dust box 17, the front side of the filter 7 is pressed against the filter guide 46 of the dust box 17. As the filter 7 is pushed in, the lift-up member 60 is pushed down while contacting the back surface of the vertical frame 21 a of the filter 7. At this time, the rack 24 of the vertical frame 21 a meshes with the pinion 40. The filter 7 is mounted at the mounting position.
　ここで、フィルタ７の装着を検出するために、リミットスイッチ６５がユニットフレーム１８に設けられている。リミットスイッチ６５は、図２，３に示すように、案内路３５の後端の近傍に配置され、左右のフィルタ７に対してそれぞれ設けられる。 Here, a limit switch 65 is provided in the unit frame 18 in order to detect the attachment of the filter 7. As shown in FIGS. 2 and 3, the limit switch 65 is disposed in the vicinity of the rear end of the guide path 35 and is provided for each of the left and right filters 7.
　フィルタ７がキャビネット３に装着されるとき、フィルタ７は案内路３５を後側に向かって移動する。フィルタ７が装着位置に達すると、リミットスイッチ６５がフィルタ７を検知する。制御装置は、リミットスイッチ６５からのオン信号によりフィルタ７が装着されたことを検出する。 When the filter 7 is mounted on the cabinet 3, the filter 7 moves along the guide path 35 toward the rear side. When the filter 7 reaches the mounting position, the limit switch 65 detects the filter 7. The control device detects that the filter 7 is attached by an ON signal from the limit switch 65.
　フィルタ清掃装置がフィルタ７を清掃するとき、制御装置は、移動部１５および清掃部１６を作動させる。ステッピングモータ４１が駆動され、ピニオン４０とガイドローラ４２が回転する。図７（ａ）に示すように、装着位置にあるフィルタ７は、案内路３５を下方向に向かって移動を開始する。フィルタ７は、フィルタガイド４６およびガイドリブ４７により、案内路３５から外れないようにガイドされながら移動する。清掃モータ５１が駆動され、回転ブラシ５０が回転する。図７（ｂ）に示すように、フィルタ７がＵターンするとき、回転ブラシ５０がフィルタ７に当たり、塵埃が掻き取られ、集塵箱４５に塵埃が溜まる。図７（ｃ）に示すように、フィルタ７が終点に達したとき、フィルタ７の後端は回転ブラシ５０に到達している。フィルタ７の前端はリミットスイッチ６５まで到達していない。このとき、ステッピングモータ４１の回転が停止される。 When the filter cleaning device cleans the filter 7, the control device operates the moving unit 15 and the cleaning unit 16. The stepping motor 41 is driven, and the pinion 40 and the guide roller 42 are rotated. As shown in FIG. 7A, the filter 7 in the mounting position starts to move downward along the guide path 35. The filter 7 moves while being guided by the filter guide 46 and the guide rib 47 so as not to be separated from the guide path 35. The cleaning motor 51 is driven and the rotary brush 50 rotates. As shown in FIG. 7B, when the filter 7 makes a U-turn, the rotary brush 50 hits the filter 7, dust is scraped off, and dust is collected in the dust collection box 45. As shown in FIG. 7C, when the filter 7 reaches the end point, the rear end of the filter 7 reaches the rotating brush 50. The front end of the filter 7 does not reach the limit switch 65. At this time, the rotation of the stepping motor 41 is stopped.
　ここで、ステッピングモータ４１が停止するタイミングは、フィルタ７が装着位置から移動したとき、リミットスイッチ６５はオフする。制御装置は、リミットスイッチ６５のオフ信号に基づいて、ステッピングモータ４１のパルス数をカウントする。予め設定されたカウント数になると、制御装置はステッピングモータ４１を停止する。このカウント数は、フィルタ７の後端が装着位置から終点である回転ブラシ５０に到達するまでの距離に対応して設定される。 Here, when the stepping motor 41 stops, the limit switch 65 is turned off when the filter 7 is moved from the mounting position. The control device counts the number of pulses of the stepping motor 41 based on the off signal of the limit switch 65. When the preset count number is reached, the control device stops the stepping motor 41. This count number is set corresponding to the distance from the mounting position until the rear end of the filter 7 reaches the rotating brush 50 that is the end point.
　この後、ステッピングモータ４１は逆回転され、フィルタ７は案内路３５を戻る。フィルタ７が戻る途中においても、回転ブラシ５０は駆動され、フィルタ７の清掃が行われる。フィルタ７の前端が回転ブラシ５０を通過し、フィルタ７が装着位置に到達すると、リミットスイッチ６５がフィルタ７を検知し、制御装置は、リミットスイッチ６５のオン信号に基づいてステッピングモータ４１および清掃モータ５１を停止する。 After this, the stepping motor 41 is reversely rotated and the filter 7 returns to the guide path 35. Even during the return of the filter 7, the rotary brush 50 is driven and the filter 7 is cleaned. When the front end of the filter 7 passes through the rotating brush 50 and the filter 7 reaches the mounting position, the limit switch 65 detects the filter 7, and the control device detects the stepping motor 41 and the cleaning motor based on the ON signal of the limit switch 65. 51 is stopped.
　なお、本発明は、上記実施形態に限定されるものではなく、本発明の範囲内で上記実施形態に多くの修正および変更を加え得ることは勿論である。上記のフィルタ、フィルタ保持装置およびフィルタ保持装置を有するフィルタ清掃装置は、空気調和機以外の空気清浄機、加湿機、除湿機に用いてもよい。なお、フィルタを保持するユニットフレームは、キャビネットに取り付けられているが、キャビネット自体がフレームとして、フィルタを移動可能に保持するようにしてもよい。また、フィルタを移動させる駆動体として、ベルトを用いてもよい。ベルトは、フィルタの左右両側を吸着あるいは挟持などにより保持して、ベルトの移動に伴ってフィルタも移動する。 In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of the present invention. The filter, the filter holding device, and the filter cleaning device having the filter holding device may be used for air purifiers, humidifiers, and dehumidifiers other than air conditioners. The unit frame for holding the filter is attached to the cabinet, but the cabinet itself may be used as a frame to hold the filter movably. Moreover, you may use a belt as a drive body which moves a filter. The belt holds both the left and right sides of the filter by suction or pinching, and the filter moves as the belt moves.
　フィルタのラックは、縦枠ではなく、メッシュ部に設けてもよい。例えば、フィルタの左右対称となる位置に偶数個のラックを形成する、あるいは左右方向の中心を通る位置に１つのラックを形成する。また、ラックの代わりに、フィルタにピニオンが入る孔を形成してもよい。回転駆動されるピニオンが孔に入り込んで、フィルタは移動する。この場合、フィルタは、前後対称、上下対称だけでなく、表裏対称とすることができる。上記のラックに対応して、複数のリフトアップ部材が設けられる。各リフトアップ部材は、左右方向に配置され、それぞれフィルタのラックの近傍に当接する。各リフトアップ部材は、連結材により一体化され、同時に上下動するようにしてもよく、あるいはそれぞれ単独で設けてもよい。 The filter rack may be provided in the mesh portion instead of the vertical frame. For example, an even number of racks are formed at positions that are symmetrical with respect to the filter, or one rack is formed at a position that passes through the center in the left-right direction. Moreover, you may form the hole into which a pinion enters into a filter instead of a rack. The rotationally driven pinion enters the hole and the filter moves. In this case, the filter can be not only front-back symmetric and vertical symmetric but also front-back symmetric. A plurality of lift-up members are provided corresponding to the rack. Each lift-up member is disposed in the left-right direction and abuts near the filter rack. Each lift-up member may be integrated by a connecting member and move up and down at the same time, or may be provided independently.
　付勢部材として、ばねの代わりにゴム等の弾性部材を用いてもよい。あるいは、リフトアップ部材自身の弾性力を利用してもよい。すなわち、可等性を有するリフトアップ部材を用い、リフトアップ部材の後側を固定する。リフトアップ部材が弾性変形することにより、リフトアップ部材の前側が上下動する。ダストボックスが装着されているとき、リフトアップ部材の前側は、フィルタを介してフィルタガイドに押え込まれ、下向きに撓む。フィルタガイドが離れると、リフトアップ部材の復元力により、リフトアップ部材の前側が上昇して、フィルタが持ち上げられる。 As the biasing member, an elastic member such as rubber may be used instead of the spring. Alternatively, the elastic force of the lift-up member itself may be used. That is, a lift-up member having equality is used, and the rear side of the lift-up member is fixed. When the lift-up member is elastically deformed, the front side of the lift-up member moves up and down. When the dust box is mounted, the front side of the lift-up member is pressed into the filter guide through the filter and bent downward. When the filter guide is separated, the front side of the lift-up member is raised by the restoring force of the lift-up member, and the filter is lifted.
　フィルタガイドとリフトアップ部材を着脱可能に連結して、フィルタガイドの移動に追従してリフトアップ部材も同時に移動するようにしてもよい。フィルタガイドに、リフトアップ部材に係合するフックを設ける。ダストボックスが装着されているとき、フックはリフトアップ部材に係合しており、ダストボックスを取り外すとき、フックがリフトアップ部材を引き上げる。リフトアップ部材の上昇に伴って、フィルタはピニオンから離れる。ダストボックスが完全に外されると、フックもリフトアップ部材から離れ、リフトアップ部材は自重で下がる。しかし、フィルタは、ピニオンから一旦離れているので、ピニオンに強固に噛み合うことはない。そのため、フィルタがピニオンに引っ掛からないように、フィルタを引き出すことができる。ダクトボックスを装着すると、フックは再びリフトアップ部材に係合する。 The filter guide and the lift-up member may be detachably connected, and the lift-up member may be moved simultaneously following the movement of the filter guide. The filter guide is provided with a hook that engages with the lift-up member. When the dust box is mounted, the hook is engaged with the lift-up member, and when removing the dust box, the hook pulls the lift-up member. As the lift-up member is raised, the filter moves away from the pinion. When the dust box is completely removed, the hook is also separated from the lift-up member, and the lift-up member is lowered by its own weight. However, since the filter is once separated from the pinion, it does not mesh firmly with the pinion. Therefore, the filter can be pulled out so that the filter is not caught by the pinion. When the duct box is installed, the hook again engages with the lift-up member.
