　なお、本実施形態において、第１保持空間２０Ａから第２保持空間２０Ｂまでのエアフィルタ１８の搬送経路を「往路」といい、第２保持空間２０Ｂから第１保持空間２０Ａまでのエアフィルタ１８の搬送経路を「復路」という。 In the present embodiment, the transport path of the air filter 18 from the first holding space 20A to the second holding space 20B is referred to as an "outward route", and the air filter 18 from the second holding space 20B to the first holding space 20A. The transport route is called the "return route".
　図３及び図４は、エアフィルタ１８の表面に付着した塵埃が除去される動作を示す拡大断面図である。 3 and 4 are enlarged cross-sectional views showing an operation of removing dust adhering to the surface of the air filter 18.
　図３及び図４に示すように、フィルタ搬送装置２２のシャフト２４の近傍には、エアフィルタ１８がシャフト２４の外周面に沿って移動するようにエアフィルタ１８を案内するガイド部材２８が設けられている。ガイド部材２８は、シャフト２４の外周面に対して所定の隙間を空けて設けられている。 As shown in FIGS. 3 and 4, a guide member 28 for guiding the air filter 18 so as to move the air filter 18 along the outer peripheral surface of the shaft 24 is provided in the vicinity of the shaft 24 of the filter transfer device 22. ing. The guide member 28 is provided with a predetermined gap from the outer peripheral surface of the shaft 24.
　また、シャフト２４の近傍には、エアフィルタ１８の表面に付着した塵埃を除去するブラシ３０が設けられている。ブラシ３０の基端部は、ブラシ駆動装置の一部であるブラシ保持部３２により保持されている。ブラシ３０及びブラシ保持部３２は、室内機１の幅方向に延在するように設けられている。即ち、ブラシ３０及びブラシ保持部３２は、エアフィルタ１８の幅方向に沿って延在し並設されている。ブラシ保持部３２は、室内機１の幅方向に延在する回転軸３２ａを中心として回転するように構成されている。ブラシ保持部３２の下方には、ブラシ３０に付着した塵埃を除去する塵埃除去部３４が設けられている。 Further, a brush 30 for removing dust adhering to the surface of the air filter 18 is provided in the vicinity of the shaft 24. The base end portion of the brush 30 is held by the brush holding portion 32 which is a part of the brush driving device. The brush 30 and the brush holding portion 32 are provided so as to extend in the width direction of the indoor unit 1. That is, the brush 30 and the brush holding portion 32 extend along the width direction of the air filter 18 and are arranged side by side. The brush holding portion 32 is configured to rotate about a rotation shaft 32a extending in the width direction of the indoor unit 1. Below the brush holding portion 32, a dust removing portion 34 for removing dust adhering to the brush 30 is provided.
　図５Ａ～図５Ｃはブラシ３０に付着した塵埃を塵埃除去部３４が掻き落とす動作を示す。図６Ａ～図６Ｄは、ブラシ３０に付着した塵埃を塵埃除去部３４が掻き落とす動作、および、掻き落とされた塵埃を掻き集める動作を示す。 5A to 5C show the operation of the dust removing unit 34 scraping off the dust adhering to the brush 30. 6A to 6D show an operation in which the dust removing unit 34 scrapes off the dust adhering to the brush 30, and an operation in which the scraped dust is collected.
　ブラシ保持部３２は、回転軸３２ａを中心として回動する。これにより、ブラシ保持部３２は、ガイド部材２８よりも往路の下流側の位置（図３におけるガイド部材２８の下端より右側の位置）において、ブラシ３０の先端部を第２保持空間２０Ｂに存在するエアフィルタ１８に接触する第１の位置（図３参照）と、塵埃除去部３４に接触可能な第２の位置（図４参照）とに配置可能である。ブラシ３０の先端部が第１の位置にあるとき、エアフィルタ１８が往路と復路の搬送経路を往復移動することにより、エアフィルタ１８に付着された塵埃がブラシ３０により掻き落とされる。一方、ブラシ保持部３２が回動して、ブラシ３０の先端部が第２の位置にあるとき、ブラシ３０に付着した塵埃に対する除去動作が開始される。ブラシ３０に付着した塵埃の除去動作は、ブラシ３０の延在方向に沿って塵埃除去部３４を移動（摺動）させて塵埃を掻き落とす「摺動掻き落とし動作」及び／又は塵埃を掻き集める「摺動掻き集め動作」を、含む。また、ブラシ３０に付着した塵埃の除去動作は、ブラシ３０を揺動させて塵埃除去部３４に接触させて、ブラシ３０の塵埃を掻き落とす「揺動掻き落とし動作」を含んでもよい。 The brush holding portion 32 rotates about the rotation shaft 32a. As a result, the brush holding portion 32 has the tip end portion of the brush 30 in the second holding space 20B at a position downstream of the guide member 28 on the downstream side (position on the right side of the lower end of the guide member 28 in FIG. 3). It can be arranged at a first position (see FIG. 3) in contact with the air filter 18 and a second position (see FIG. 4) in contact with the dust removing portion 34. When the tip of the brush 30 is in the first position, the air filter 18 reciprocates in the transport path of the outward path and the return path, so that the dust adhering to the air filter 18 is scraped off by the brush 30. On the other hand, when the brush holding portion 32 rotates and the tip portion of the brush 30 is in the second position, the removing operation for the dust adhering to the brush 30 is started. The dust removing operation of the brush 30 is a "sliding scraping operation" in which the dust removing portion 34 is moved (sliding) along the extending direction of the brush 30 to scrape off the dust and / or the dust is collected. Includes "sliding scraping operation". Further, the dust removing operation of the brush 30 may include a "swinging scraping operation" in which the brush 30 is shaken and brought into contact with the dust removing portion 34 to scrape off the dust of the brush 30.
　塵埃除去部３４は、図６Ｃ～図６Ｄに示すように、ブラシ３０に接触した状態でブラシ３０の延在方向（すなわち、室内機の幅方向）に移動することによって、ブラシ３０に付着した塵埃を掻き落とすように構成されている。塵埃除去部３４は、第１部品３６と第２部品３８とを備えている。第２部品３８は、第１部品３６に対して取り外し可能に構成されている。塵埃除去部３４の具体的構成については、後で詳しく説明する。 As shown in FIGS. 6C to 6D, the dust removing unit 34 moves in the extending direction of the brush 30 (that is, the width direction of the indoor unit) in contact with the brush 30, so that the dust adheres to the brush 30. It is configured to scrape off. The dust removing unit 34 includes a first component 36 and a second component 38. The second component 38 is configured to be removable with respect to the first component 36. The specific configuration of the dust removing unit 34 will be described in detail later.
　塵埃除去部３４の下方には、塵埃除去部３４に掻き落とされた塵埃を受ける塵埃受け部４０が設けられている。塵埃受け部４０は、上面が開口する箱状に構成されている。 Below the dust removing unit 34, a dust receiving unit 40 that receives the dust scraped off by the dust removing unit 34 is provided. The dust receiving portion 40 is configured in a box shape having an open upper surface.

Further, FIG. 9 is a perspective view showing a state in which the dust receiving portion 40 is removed from the filter device 3.
　図７及び図８に示すように、塵埃受け部４０は、室内機の幅方向に延在するように設けられている。塵埃受け部４０には、塵埃除去部３４の第１部品３６から取り外した第２部品３８を外部に取り出すための開口部４０ａが設けられている。塵埃受け部４０は、第１部品３６と第２部品３８とが組み立てられた状態では、塵埃除去部３４によってフィルタ装置３に対する着脱が阻害されるように構成されている。一方、図９に示すように、塵埃除去部３４において第１部品３６から第２部品３８が取り外された状態では、塵埃受け部４０はフィルタ装置３に対して着脱可能となる。 As shown in FIGS. 7 and 8, the dust receiving portion 40 is provided so as to extend in the width direction of the indoor unit. The dust receiving portion 40 is provided with an opening 40a for taking out the second component 38 removed from the first component 36 of the dust removing portion 34 to the outside. The dust receiving portion 40 is configured such that when the first component 36 and the second component 38 are assembled, the dust removing portion 34 prevents attachment / detachment to / from the filter device 3. On the other hand, as shown in FIG. 9, when the second component 38 is removed from the first component 36 in the dust removing portion 34, the dust receiving portion 40 can be attached to and detached from the filter device 3.
　塵埃受け部４０の端部には、塵埃受け部４０内の塵埃を吸引する吸引装置（排気装置ともいう）４２が接続されている。吸引装置４２は、吸引管４４と、吸引管４４に吸引力を発生させる吸引ファン４６とを備えている。吸引管４４の一端部４４ａには塵埃吸引部４８が設けられている。塵埃吸引部４８は塵埃受け部４０の端部の吸引穴４０ｂに接続されている。吸引管４４の他端部４４ｂは開口している。吸引管４４の他端部４４ｂは、吸引管４４内を通る塵埃を室外に排出できるように、一端が室外に開口した排気ホース（図示せず）に接続される。塵埃除去部３４が吸引装置４２に向けて移動することによって、塵埃受け部４０内の塵埃が吸引装置４２に向けて移動される。 A suction device (also referred to as an exhaust device) 42 for sucking dust in the dust receiving portion 40 is connected to the end of the dust receiving portion 40. The suction device 42 includes a suction pipe 44 and a suction fan 46 that generates a suction force in the suction pipe 44. A dust suction portion 48 is provided at one end portion 44a of the suction pipe 44. The dust suction unit 48 is connected to a suction hole 40b at the end of the dust receiving unit 40. The other end 44b of the suction pipe 44 is open. The other end 44b of the suction pipe 44 is connected to an exhaust hose (not shown) having one end opened to the outside so that dust passing through the suction pipe 44 can be discharged to the outside. As the dust removing unit 34 moves toward the suction device 42, the dust in the dust receiving unit 40 is moved toward the suction device 42.
　次に、塵埃除去部３４及び塵埃受け部４０の構成について、より具体的に説明する。図１０は、塵埃除去部３４の斜視図である。図１１は塵埃除去部３４の分解斜視図である。図１２は、塵埃除去部３４の前面図である。図１３は、図１２のＡ１－Ａ１線断面図である。なお、塵埃除去部３４において、吸引装置４２に近い側を「前」といい、吸引装置４２から離れる側を「後」という。 Next, the configurations of the dust removing unit 34 and the dust receiving unit 40 will be described more specifically. FIG. 10 is a perspective view of the dust removing unit 34. FIG. 11 is an exploded perspective view of the dust removing unit 34. FIG. 12 is a front view of the dust removing unit 34. FIG. 13 is a sectional view taken along line A1-A1 of FIG. In the dust removing unit 34, the side closer to the suction device 42 is referred to as "front", and the side away from the suction device 42 is referred to as "rear".
　図１０に示すように、塵埃除去部３４は、ブラシ３０に付着した塵埃を掻き落とす前方ブレード３４ａ及び後方ブレード３４ｂを有している。前方ブレード３４ａと後方ブレード３４ｂとは、ブラシ３０の延在方向に対して交差（例えば、直交）する方向にそれぞれ延在している。前方ブレード３４ａと後方ブレード３４ｂとは、ブラシ３０の延在方向に互いに間隔を空けて配置されている。実施形態１において、前方ブレード３４ａ及び後方ブレード３４ｂの吸引装置４２側の前端部は、ブラシ３０に付着した塵埃の除去効率の向上のため、エッジ状（直角又は鋭角）に形成されている。 As shown in FIG. 10, the dust removing unit 34 has a front blade 34a and a rear blade 34b that scrape off the dust adhering to the brush 30. The front blade 34a and the rear blade 34b extend in directions intersecting (for example, orthogonally) with respect to the extending direction of the brush 30. The front blade 34a and the rear blade 34b are arranged at intervals in the extending direction of the brush 30. In the first embodiment, the front end portions of the front blade 34a and the rear blade 34b on the suction device 42 side are formed in an edge shape (right angle or acute angle) in order to improve the efficiency of removing dust adhering to the brush 30.
　前方ブレード３４ａの厚さ（高さ）は、絡み合って纏まった塵埃の塊が前方ブレード３４ａに巻き付かないような寸法（例えば、２ｍｍ以上）に設計されている。 The thickness (height) of the front blade 34a is designed so that entangled and collected dust lumps do not wrap around the front blade 34a (for example, 2 mm or more).
　また、塵埃除去部３４は、第１側壁３４ｃ及び第２側壁３４ｄが前方ブレード３４ａの前端部よりも前方（吸引装置４２側）に突き出すように構成されている。第１側壁３４ｃと第２側壁３４ｄと前方ブレード３４ａとで、前側空間Ｓ１が区画されている。前方ブレード３４ａによりブラシ３０から掻き取った塵埃の塊は、前側空間Ｓ１からはみ出すことが抑えられ、塵埃受け部４０の内底面４０ｃ上に落下し易くなっている。塵埃除去部３４の第１側壁３４ｃ及び第２側壁３４ｄが前方ブレード３４ａよりも前方に突き出す長さは、例えば、７ｍｍ以上である。 Further, the dust removing portion 34 is configured such that the first side wall 34c and the second side wall 34d project forward (on the suction device 42 side) from the front end portion of the front blade 34a. The front side space S1 is partitioned by the first side wall 34c, the second side wall 34d, and the front blade 34a. The dust mass scraped from the brush 30 by the front blade 34a is suppressed from protruding from the front space S1 and easily falls on the inner bottom surface 40c of the dust receiving portion 40. The length of the first side wall 34c and the second side wall 34d of the dust removing portion 34 protruding forward from the front blade 34a is, for example, 7 mm or more.
　前方ブレード３４ａ及び後方ブレード３４ｂの少なくとも一方は、ブラシ保持部３２の回転軸３２ａを中心とする円弧状に形成されている。実施形態１においては、前方ブレード３４ａ及び後方ブレード３４ｂの両方が、ブラシ保持部３２の回転軸３２ａを中心とする円弧状に形成されている。 At least one of the front blade 34a and the rear blade 34b is formed in an arc shape centered on the rotation axis 32a of the brush holding portion 32. In the first embodiment, both the front blade 34a and the rear blade 34b are formed in an arc shape centered on the rotation shaft 32a of the brush holding portion 32.
　前方ブレード３４ａと後方ブレード３４ｂとの間には、後方ブレード３４ｂによりブラシ３０から掻き取った塵埃の塊を落下させるための後側空間Ｓ２が設けられている。前方ブレード３４ａと後方ブレード３４ｂとの間隔は、後方ブレード３４ｂによりブラシ３０から掻き取った塵埃の塊が後側空間Ｓ２を通じてより確実に落下するように、例えば、１４ｍｍ以上に設計されている。 A rear space S2 for dropping a lump of dust scraped from the brush 30 by the rear blade 34b is provided between the front blade 34a and the rear blade 34b. The distance between the front blade 34a and the rear blade 34b is designed to be, for example, 14 mm or more so that the dust mass scraped from the brush 30 by the rear blade 34b falls more reliably through the rear space S2.
　また、塵埃除去部３４は、ブラシ３０の延在方向（図５Ａ～図５Ｃでは奥行き方向）から見て、ブラシ３０の揺動範囲内に配置され、ブラシ３０に付着した塵埃を掻き落とす少なくとも１つの側方ブレードを有している。実施形態１において、塵埃除去部３４は、ブラシ３０の延在方向に延在する２つの側方ブレード３４ｅ，３４ｆを有している。後側空間Ｓ２は、前方ブレード３４ａ、後方ブレード３４ｂ、及び側方ブレード３４ｅ，３４ｆによって区画されている。前方ブレード３４ａ、後方ブレード３４ｂ、及び側方ブレード３４ｅ，３４ｆは、塵埃を掻き落とし易く、摺動性に優れた材質、例えばポリアセタールで構成されている。図５Ａ～図５Ｃに示すようにブラシ３０が揺動することによって、ブラシ３０と側方ブレード３４ｅ，３４ｆとが接触し、側方ブレード３４ｅ，３４ｆによりブラシ３０から掻き取った塵埃の塊が後側空間Ｓ２を通じて落下する。実施形態１において、前方ブレード３４ａ及び後方ブレード３４ｂの吸引装置４２側の前端部は、ブラシ３０に付着した塵埃の除去効率の向上のため、エッジ状（直角又は鋭角）に形成されている。 Further, the dust removing portion 34 is arranged within the swing range of the brush 30 when viewed from the extending direction of the brush 30 (the depth direction in FIGS. 5A to 5C), and at least 1 for scraping off the dust adhering to the brush 30. It has two side blades. In the first embodiment, the dust removing unit 34 has two side blades 34e and 34f extending in the extending direction of the brush 30. The rear space S2 is partitioned by a front blade 34a, a rear blade 34b, and side blades 34e and 34f. The front blade 34a, the rear blade 34b, and the side blades 34e and 34f are made of a material that easily scrapes off dust and has excellent slidability, for example, polyacetal. As shown in FIGS. 5A to 5C, when the brush 30 swings, the brush 30 and the side blades 34e and 34f come into contact with each other, and a mass of dust scraped from the brush 30 by the side blades 34e and 34f is rearward. It falls through the side space S2. In the first embodiment, the front end portions of the front blade 34a and the rear blade 34b on the suction device 42 side are formed in an edge shape (right angle or acute angle) in order to improve the efficiency of removing dust adhering to the brush 30.
　また、塵埃除去部３４は、吸引装置４２に近づくに従い下方に傾斜又は湾曲する誘導面３４ｇを有している。実施形態１において、誘導面３４ｇは、吸引装置４２に近づくに従い下方に傾斜する傾斜面である。誘導面３４ｇの水平面に対する傾斜角度は、例えば、３０度以上４０度以下である。塵埃除去部３４は、重力を利用し、誘導面３４ｇによってブラシ３０から掻き落とされた塵埃を塵埃除去部３４よりも吸引装置４２側に位置する塵埃受け部４０の内底面４０ｃへ誘導するように構成されている。 Further, the dust removing unit 34 has a guide surface 34 g that inclines or curves downward as it approaches the suction device 42. In the first embodiment, the guide surface 34g is an inclined surface that inclines downward as it approaches the suction device 42. The inclination angle of the guide surface 34 g with respect to the horizontal plane is, for example, 30 degrees or more and 40 degrees or less. The dust removing unit 34 uses gravity to guide the dust scraped off from the brush 30 by the guiding surface 34g to the inner bottom surface 40c of the dust receiving unit 40 located closer to the suction device 42 than the dust removing unit 34. It is configured.
　また、塵埃除去部３４は、ブラシ３０と接触した状態において、塵埃受け部４０内における塵埃除去部３４より吸引装置４２に近い後方空間と塵埃除去部３４より吸引装置４２から離れた前方空間とを連通する吸気穴３４ｉを有している。実施形態１において、吸気穴３４ｉは、図１０に示すように、上方に向けて開口している。実施形態１において、前方ブレード３４ａ、後方ブレード３４ｂ、側方ブレード３４ｅ，３４ｆ、誘導面３４ｇ、及び吸気穴３４ｉは、第１部品３６に設けられている。 Further, the dust removing unit 34 provides a rear space closer to the suction device 42 than the dust removing unit 34 and a front space away from the suction device 42 from the dust removing unit 34 in the dust receiving unit 40 in a state of being in contact with the brush 30. It has an intake hole 34i for communication. In the first embodiment, the intake hole 34i is opened upward as shown in FIG. In the first embodiment, the front blade 34a, the rear blade 34b, the side blades 34e and 34f, the guide surface 34g, and the intake hole 34i are provided in the first component 36.
　また、塵埃除去部３４は、誘導面３４ｇの下方に、塵埃除去部３４が吸引装置４２に向けて移動するときに塵埃受け部４０内の塵埃を吸引装置４２に向けて押圧する押圧面３４ｈを有している。押圧面３４ｈは、誘導面３４ｇよりも鉛直方向に対する傾斜角度が小さくなるように設計されている。実施形態１において、押圧面３４ｈは、鉛直方向に延在する平面である。 Further, the dust removing unit 34 has a pressing surface 34h below the guide surface 34g that presses the dust in the dust receiving unit 40 toward the suction device 42 when the dust removing unit 34 moves toward the suction device 42. Have. The pressing surface 34h is designed so that the inclination angle with respect to the vertical direction is smaller than that of the guiding surface 34g. In the first embodiment, the pressing surface 34h is a plane extending in the vertical direction.
　図１４Ａ～図１４Ｄは、塵埃除去部３４が塵埃受け部４０の内底面４０ｃに沿って移動する様子を示す側面図である。 14A to 14D are side views showing how the dust removing portion 34 moves along the inner bottom surface 40c of the dust receiving portion 40.
　塵埃受け部４０の内底面４０ｃに対向する塵埃除去部３４の底面３４ｊは、吸引装置４２（図の左側）に近づくに従い内底面４０ｃに近づくように傾斜又は湾曲するように構成されている。実施形態１において、塵埃除去部３４の底面３４ｊは、下方に突出する湾曲面である。また、塵埃受け部４０の内底面４０ｃは、吸引装置４２から離れるように塵埃が移動するときに当該塵埃が受ける摩擦力が、吸引装置４２に近づくように塵埃が移動するときに当該塵埃が受ける摩擦力よりも大きくなるように構成されている。実施形態１において、塵埃受け部４０の内底面４０ｃは、図１４Ａ～図１４Ｄに示すように、断面がのこぎり波状に構成されている。 The bottom surface 34j of the dust removing portion 34 facing the inner bottom surface 40c of the dust receiving portion 40 is configured to be inclined or curved so as to approach the inner bottom surface 40c as it approaches the suction device 42 (left side in the figure). In the first embodiment, the bottom surface 34j of the dust removing portion 34 is a curved surface protruding downward. Further, the inner bottom surface 40c of the dust receiving portion 40 receives the frictional force received by the dust when the dust moves away from the suction device 42, and receives the dust when the dust moves closer to the suction device 42. It is configured to be greater than the frictional force. In the first embodiment, the inner bottom surface 40c of the dust receiving portion 40 has a saw-like cross section as shown in FIGS. 14A to 14D.
　この構成により、塵埃除去部３４よりも吸引装置４２から離れた位置に落下した塵埃の塊は、図１４Ａ～図１４Ｃに示すように、塵埃除去部３４が吸引装置４２から離れるように移動することで、塵埃除去部３４よりも吸引装置４２側に移動し易くなる。その後、図１４Ｄに示すように、塵埃除去部３４が吸引装置４２に近づくように移動することで、塵埃除去部３４は、押圧面３４ｈにより塵埃の塊を吸引装置４２に向けて移動させることができる。実施形態１において、押圧面３４ｈ及び底面３４ｊは、第２部品３８に設けられている。 With this configuration, the dust mass that has fallen away from the suction device 42 than the dust removing unit 34 moves so that the dust removing unit 34 moves away from the suction device 42, as shown in FIGS. 14A to 14C. Therefore, it becomes easier to move to the suction device 42 side than the dust removing unit 34. After that, as shown in FIG. 14D, the dust removing unit 34 moves so as to approach the suction device 42, so that the dust removing unit 34 can move the dust mass toward the suction device 42 by the pressing surface 34h. it can. In the first embodiment, the pressing surface 34h and the bottom surface 34j are provided on the second component 38.
　次に、エアフィルタ１８に付着した塵埃を屋外に排出する清掃動作の一例について説明する。なお、以下に説明するエアフィルタ１８の清掃動作、および、ブラシ３０に付着した塵埃の除去動作は、制御部８０の制御の下で行われる。 Next, an example of a cleaning operation for discharging the dust adhering to the air filter 18 to the outside will be described. The cleaning operation of the air filter 18 and the removing operation of dust adhering to the brush 30 described below are performed under the control of the control unit 80.
　エアフィルタ１８の清掃動作の前において、塵埃除去部３４は、図６Ａに示すように、吸引装置４２に最も近い端点位置Ｔ２に位置する。なお、塵埃除去部３４は、本体２の空調運転開始とともに、任意に定めた位置まで摺動動作してもよい。そして、当該位置にて例えばリミットスイッチなどでリセット動作が行われ、原点位置が認識されてもよい。この場合、任意に定めた位置は、吸引装置４２に最も近い端点位置であってもよい。 Before the cleaning operation of the air filter 18, the dust removing unit 34 is located at the end point position T2 closest to the suction device 42, as shown in FIG. 6A. The dust removing unit 34 may slide to an arbitrarily determined position when the air conditioning operation of the main body 2 is started. Then, a reset operation may be performed at that position by, for example, a limit switch, and the origin position may be recognized. In this case, the arbitrarily determined position may be the end point position closest to the suction device 42.
　この状態から図示しないコントローラが操作されるなどして、エアフィルタ１８の清掃動作の開始が指示されると、制御部８０は、図６Ｂに示すように、塵埃除去部３４を、塵埃受け部４０内におけるブラシ３０の延在方向において吸引装置４２か最も離れた開始位置Ｔ１（待機位置）に移動させる。また、図４の状態からギヤ２６が正方向（図４では反時計回り）に回転される。これにより、エアフィルタ１８が第１保持空間２０Ａから第２保持空間２０Ｂへ搬送される。エアフィルタ１８の先端部がブラシ保持部３２とシャフト２４との間を通過するとき、ブラシ保持部３２が正方向（図４では反時計回り）又は逆方向（図４では時計回り）に回転して、ブラシ３０の先端部がエアフィルタ１８の先端部と網部分とに跨るように接触する。 When a controller (not shown) is operated from this state to instruct the start of the cleaning operation of the air filter 18, the control unit 80 sets the dust removing unit 34 to the dust receiving unit 40 as shown in FIG. 6B. The brush 30 is moved to the suction device 42 or the farthest start position T1 (standby position) in the extending direction of the brush 30. Further, the gear 26 is rotated in the positive direction (counterclockwise in FIG. 4) from the state shown in FIG. As a result, the air filter 18 is conveyed from the first holding space 20A to the second holding space 20B. When the tip of the air filter 18 passes between the brush holding portion 32 and the shaft 24, the brush holding portion 32 rotates in the forward direction (counterclockwise in FIG. 4) or in the reverse direction (clockwise in FIG. 4). The tip of the brush 30 comes into contact with the tip of the air filter 18 so as to straddle the net portion.
　ギヤ２６が更に正方向に回転されると、エアフィルタ１８が更に第２保持空間２０Ｂへと搬送される。この搬送の間、ブラシ保持部３２は、図３に示すように、ブラシ３０をエアフィルタ１８と接触する位置で固定する。これにより、エアフィルタ１８に付着した塵埃は、定位置で固定されるブラシ３０で堰き止められ、ブラシ３０のエアフィルタ１８の搬送方向の上流側に溜められる。このとき、ブラシ３０に溜められた塵埃とエアフィルタ１８に付着した塵埃とが絡み合って紙縒のように纏まる。これにより、エアフィルタ１８に付着した塵埃を除去することができる。ブラシ３０に付着した塵埃の一部は、塵埃受け部４０の内底面４０ｃ上に落ちる。 When the gear 26 is further rotated in the positive direction, the air filter 18 is further conveyed to the second holding space 20B. During this transfer, the brush holding portion 32 fixes the brush 30 at a position where it comes into contact with the air filter 18, as shown in FIG. As a result, the dust adhering to the air filter 18 is blocked by the brush 30 fixed at a fixed position, and is collected on the upstream side of the brush 30 in the transport direction of the air filter 18. At this time, the dust collected in the brush 30 and the dust adhering to the air filter 18 are entangled and gathered like a paper twist. As a result, the dust adhering to the air filter 18 can be removed. A part of the dust adhering to the brush 30 falls on the inner bottom surface 40c of the dust receiving portion 40.
　ギヤ２６が更に正方向に回転され、エアフィルタ１８が第２保持空間２０Ｂに到達すると、ギヤ２６の正方向の回転が停止される。このとき、ブラシ３０の先端部の少なくとも一部は、エアフィルタ１８の清掃領域外にあるエアフィルタ１８の後端部（枠体部分）に接触した状態にある。 When the gear 26 is further rotated in the positive direction and the air filter 18 reaches the second holding space 20B, the rotation of the gear 26 in the positive direction is stopped. At this time, at least a part of the tip portion of the brush 30 is in contact with the rear end portion (frame body portion) of the air filter 18 outside the cleaning area of the air filter 18.
　その後、ブラシ保持部３２が正方向（図３では反時計回り）に回転され、図５Ｂに示すように、ブラシ３０が塵埃除去部３４の前方ブレード３４ａ及び後方ブレード３４ｂに接触可能な位置に移動する。 After that, the brush holding portion 32 is rotated in the forward direction (counterclockwise in FIG. 3), and as shown in FIG. 5B, the brush 30 moves to a position where it can contact the front blade 34a and the rear blade 34b of the dust removing portion 34. To do.
　その後、図６Ｃ及び図６Ｄに示すように、制御部８０は、塵埃除去部３４を吸引装置４２（吸引穴４０ｂ）に近づくように移動させる。これにより、ブラシ３０に付着した塵埃が前方ブレード３４ａ及び後方ブレード３４ｂにより掻き落とされる。掻き落とされた塵埃は、誘導面３４ｇによって塵埃受け部４０の内底面４０ｃへ誘導される。このとき、誘導面３４ｇによって誘導された塵埃は、ブラシ３０の延在方向において、塵埃除去部３４よりも吸引装置４２側に位置する。また、塵埃受け部４０の内底面４０ｃへ誘導された塵埃は、塵埃除去部３４の押圧面３４ｈによって吸引装置４２に向けて押圧される。塵埃除去部３４の移動速度は、例えば、５ｍｍ／秒である。 After that, as shown in FIGS. 6C and 6D, the control unit 80 moves the dust removing unit 34 so as to approach the suction device 42 (suction hole 40b). As a result, the dust adhering to the brush 30 is scraped off by the front blade 34a and the rear blade 34b. The scraped dust is guided to the inner bottom surface 40c of the dust receiving portion 40 by the guiding surface 34g. At this time, the dust induced by the guiding surface 34g is located closer to the suction device 42 than the dust removing portion 34 in the extending direction of the brush 30. Further, the dust guided to the inner bottom surface 40c of the dust receiving portion 40 is pressed toward the suction device 42 by the pressing surface 34h of the dust removing portion 34. The moving speed of the dust removing unit 34 is, for example, 5 mm / sec.
　また、図６Ｃに示すように、制御部８０は、塵埃除去部３４が開始位置Ｔ１からブラシ３０の延在方向に移動しているときに、ブラシ３０の中間地点等の任意に定めた位置で、少なくとも１回反復動作（第１の反復動作とも称する）させてもよい。反復動作は往復動作よりも短い距離で行われ、例えば、１０ｃｍ～３５ｃｍの幅で摺動動作が行われる。これにより、ブラシ３０に付着した塵埃を、塊が過剰に大きくなる前に、塵埃受け部４０へ掻き落とすことができる。 Further, as shown in FIG. 6C, the control unit 80 is at an arbitrarily determined position such as an intermediate point of the brush 30 when the dust removing unit 34 is moving from the start position T1 in the extending direction of the brush 30. , At least one repetitive motion (also referred to as a first repetitive motion) may be performed. The repetitive motion is performed at a shorter distance than the reciprocating motion, for example, the sliding motion is performed with a width of 10 cm to 35 cm. As a result, the dust adhering to the brush 30 can be scraped off to the dust receiving portion 40 before the lump becomes excessively large.
　また、制御部８０は、塵埃除去部３４の移動中において、ブラシ保持部３２を回転軸３２ａを中心として正逆回転させる。これにより、ブラシ３０の延在方向と交差する方向にブラシ３０が揺動する動作が行われる。これにより、ブラシ３０から掻き取られた塵埃の塊が、過剰に大きくなる前に、側方ブレード３４ｅ，３４ｆによって塵埃受け部４０の内底面４０ｃへ掻き落とされる。 Further, the control unit 80 rotates the brush holding unit 32 in the forward and reverse directions around the rotation shaft 32a while the dust removing unit 34 is moving. As a result, the brush 30 swings in the direction intersecting the extending direction of the brush 30. As a result, the dust mass scraped from the brush 30 is scraped off to the inner bottom surface 40c of the dust receiving portion 40 by the side blades 34e and 34f before becoming excessively large.
　その後、図６Ｄに示すように、制御部８０により、塵埃除去部３４が吸引穴４０ｂ(吸引穴４０ｂの近傍を含む）まで移動されると、制御部８０は吸引装置４２の吸引ファン４６を駆動する。これにより、吸引管４４内に吸引力となる気流が発生する。この気流により、塵埃除去部３４の押圧面３４ｈによって吸引穴４０(吸引穴４０ｂの近傍を含む）に集められた塵埃の塊が吸引管４４を通じて室外に排出される。 After that, as shown in FIG. 6D, when the dust removing unit 34 is moved to the suction hole 40b (including the vicinity of the suction hole 40b) by the control unit 80, the control unit 80 drives the suction fan 46 of the suction device 42. To do. As a result, an air flow that serves as a suction force is generated in the suction pipe 44. Due to this air flow, a mass of dust collected in the suction hole 40 (including the vicinity of the suction hole 40b) by the pressing surface 34h of the dust removing portion 34 is discharged to the outside through the suction pipe 44.
　また、図６Ｄに示すように、制御部８０は、塵埃除去部３４が吸引穴４０ｂ(吸引穴４０ｂの近傍を含む）に到達したときに、少なくとも１回反復動作（第２の反復動作とも称する）を行ってもよい。反復動作は往復動作よりも短い距離で行われ、例えば、４ｃｍ～６ｃｍの幅で摺動動作が行われる。これにより、塵埃受け部４０に掻き落とされた塵埃をより効率よく短時間で屋外へ排出することができる。 Further, as shown in FIG. 6D, when the dust removing unit 34 reaches the suction hole 40b (including the vicinity of the suction hole 40b), the control unit 80 repeats at least once (also referred to as a second repeating operation). ) May be performed. The repetitive motion is performed at a shorter distance than the reciprocating motion, for example, the sliding motion is performed with a width of 4 cm to 6 cm. As a result, the dust scraped off by the dust receiving portion 40 can be more efficiently discharged to the outside in a short time.
　その後、制御部８０は、塵埃除去部３４を吸引装置４２から最も離れた開始位置Ｔ１（待機位置）へ再度移動させてもよい。このとき、塵埃除去部３４よりも吸引装置４２から離れた塵埃受け部４０の内底面４０ｃ上に落下した塵埃は、図１４Ａ～図１４Ｃを参照して説明したように、塵埃除去部３４よりも吸引装置４２側に移動する。 After that, the control unit 80 may move the dust removing unit 34 again to the start position T1 (standby position) farthest from the suction device 42. At this time, the dust that has fallen on the inner bottom surface 40c of the dust receiving unit 40, which is farther from the suction device 42 than the dust removing unit 34, is more than the dust removing unit 34 as described with reference to FIGS. 14A to 14C. Move to the suction device 42 side.
　その後、図６Ｃ及び図６Ｄに示すように、制御部８０は、塵埃除去部３４を吸引装置４２に近づくように再度移動させる。これにより、塵埃除去部３４よりも吸引装置４２側に移動した塵埃が、図１４Ｄに示すように、塵埃除去部３４の押圧面３４ｈによって吸引装置４２に向けて押圧される。 After that, as shown in FIGS. 6C and 6D, the control unit 80 moves the dust removing unit 34 again so as to approach the suction device 42. As a result, the dust that has moved closer to the suction device 42 than the dust removing unit 34 is pressed toward the suction device 42 by the pressing surface 34h of the dust removing unit 34, as shown in FIG. 14D.
　その後、図６Ｄに示すように、制御部８０は、塵埃除去部３４が吸引穴４０ｂ(吸引穴４０ｂの近傍を含む）まで移動されると、吸引装置４２の吸引ファン４６を駆動する。これにより、吸引管４４内に吸引力となる気流が発生する。この気流により、塵埃除去部３４の押圧面３４ｈによって吸引穴４０ｂの近傍に集められた塵埃の塊が吸引管４４を通じて室外に排出される。なお、この塵埃除去部３４の移動及び吸引装置４２による吸引動作は、複数回行われてもよい。これにより、エアフィルタ１８の清掃動作が完了する。 After that, as shown in FIG. 6D, when the dust removing unit 34 is moved to the suction hole 40b (including the vicinity of the suction hole 40b), the control unit 80 drives the suction fan 46 of the suction device 42. As a result, an air flow that serves as a suction force is generated in the suction pipe 44. Due to this air flow, a mass of dust collected in the vicinity of the suction hole 40b by the pressing surface 34h of the dust removing portion 34 is discharged to the outside through the suction pipe 44. The movement of the dust removing unit 34 and the suction operation by the suction device 42 may be performed a plurality of times. As a result, the cleaning operation of the air filter 18 is completed.
　実施の形態１に係る空気調和機では、吸引装置４２により塵埃受け部４０内の塵埃を吸引して室外へ排出するようにしたがこれに限られない。塵埃受け部４０がフィルタ装置３から取り外されることで、塵埃受け部４０内の塵埃を使用者の手動で排出することも可能である。以下、塵埃受け部４０内の塵埃を使用者の手動で排出する動作について、詳細に説明する。 In the air conditioner according to the first embodiment, the suction device 42 sucks the dust in the dust receiving portion 40 and discharges it to the outside, but the present invention is not limited to this. By removing the dust receiving portion 40 from the filter device 3, it is possible for the user to manually discharge the dust in the dust receiving portion 40. Hereinafter, the operation of manually discharging the dust in the dust receiving unit 40 will be described in detail.
　（使用者の手動による塵埃排出について）
　図７、図８に示すように、使用者が塵埃受け部４０に設けられた蓋４７を外して、塵埃除去部３４の第１部品３６から第２部品３８を外す。そして、図９に示すように、使用者は塵埃受け部４０を手前へ引き出す。そして、塵埃受け部４０の内部に溜まった塵埃をごみ箱などに捨てることにより、塵埃受け部４０の掃除を手動で行うことができる。 (About manual dust discharge by the user)
As shown in FIGS. 7 and 8, the user removes the lid 47 provided on the dust receiving portion 40, and removes the second component 38 from the first component 36 of the dust removing portion 34. Then, as shown in FIG. 9, the user pulls out the dust receiving portion 40 toward the front. Then, by discarding the dust accumulated inside the dust receiving portion 40 into a trash can or the like, the dust receiving portion 40 can be manually cleaned.
　なお、塵埃除去部３４は、第１部品３６に対して、第２部品３８が脱着可能に構成されている。図１１に示すように第１部品３６には塵埃除去部３４の摺動動作の方向と直交する方向に延設された嵌合凹部３４ｍが形成されている。一方、第２部品３８には、第１部品３６の嵌合凹部３４ｍと嵌合する嵌合凸部３４ｎが突設されている。このように構成された第１部品３６及び第２部品３８は、摺動動作の方向と直交する方向に抜き差しして脱着可能であり、ボルト７０により互いに固着されている。 The dust removing unit 34 is configured such that the second component 38 can be attached to and detached from the first component 36. As shown in FIG. 11, the first component 36 is formed with a fitting recess 34 m extending in a direction orthogonal to the sliding operation direction of the dust removing portion 34. On the other hand, the second component 38 is provided with a fitting convex portion 34n that fits with the fitting recess 34m of the first component 36. The first component 36 and the second component 38 configured in this way can be inserted and removed in a direction orthogonal to the direction of the sliding operation, and are fixed to each other by bolts 70.
　また、図１５Ａは、第２部品３８を取り外した塵埃除去部３４と、塵埃受け部４０とを拡大した断面図である。この図に示すように、第２部品３８を取り外すと、塵埃受け部４０の背壁４０ｄを拘束するものが無くなるため、図１５Ｂに示すように、使用者が塵埃受け部４０を手前へ引き出すことが可能となる。 Further, FIG. 15A is an enlarged cross-sectional view of the dust removing portion 34 from which the second component 38 has been removed and the dust receiving portion 40. As shown in this figure, when the second component 38 is removed, there is nothing that restrains the back wall 40d of the dust receiving portion 40. Therefore, as shown in FIG. 15B, the user pulls out the dust receiving portion 40 toward the front. Is possible.
　また、図１６Ａに示すように、塵埃受け部４０の底面には、吸引装置４２に連通する吸引穴４０ｂと、スライド式の蓋４９とが設けられている。前記スライド式の蓋４９はスライド可動できるように構成されており、図１６Ｂに示すように、吸引穴４０ｂを閉塞することが可能である。これにより、吸引穴４０ｂを吸引装置４２と遮断することができるとともに、塵埃受け部４０へ掻き落とされた塵埃を塵埃受け部４０外へ溢すことなく集塵することが可能である。そして、塵埃受け部４０の内部に溜まった塵埃をごみ箱などに捨てることにより、塵埃受け部４０の掃除を手動で行うことができる。 Further, as shown in FIG. 16A, a suction hole 40b communicating with the suction device 42 and a sliding lid 49 are provided on the bottom surface of the dust receiving portion 40. The slide-type lid 49 is configured to be slidable, and as shown in FIG. 16B, the suction hole 40b can be closed. As a result, the suction hole 40b can be shut off from the suction device 42, and the dust scraped off by the dust receiving portion 40 can be collected without overflowing to the outside of the dust receiving portion 40. Then, by discarding the dust accumulated inside the dust receiving portion 40 into a trash can or the like, the dust receiving portion 40 can be manually cleaned.
　次に、塵埃が手動で排出される場合において、エアフィルタ１８に付着した塵埃が塵埃受け部４０に掻き落される清掃動作について説明する。この清掃動作は制御部８０の制御の下で行われる。 Next, a cleaning operation in which the dust adhering to the air filter 18 is scraped off by the dust receiving portion 40 when the dust is manually discharged will be described. This cleaning operation is performed under the control of the control unit 80.
　エアフィルタ１８の清掃動作の前においては、塵埃除去部３４は、図１７Ａに示すように吸引装置４２に最も近い端点位置Ｔ２に位置している。この状態から、エアフィルタ１８の清掃動作の開始が指示されると、制御部８０は、図１７Ｂに示すように、塵埃除去部３４を端点位置Ｔ２から最も離れた待機位置へと移動させる。また、図４の状態からギヤ２６が正方向（図４では反時計回り）に回転される。これにより、エアフィルタ１８が第１保持空間２０Ａから第２保持空間２０Ｂへ搬送される。エアフィルタ１８の先端部がブラシ保持部３２とシャフト２４との間を通過するとき、ブラシ保持部３２が正方向（図４では反時計回り）又は逆方向（図４では時計回り）に回転して、ブラシ３０の先端部がエアフィルタ１８の先端部と網部分とに跨るように接触する。 Before the cleaning operation of the air filter 18, the dust removing unit 34 is located at the end point position T2 closest to the suction device 42 as shown in FIG. 17A. When the start of the cleaning operation of the air filter 18 is instructed from this state, the control unit 80 moves the dust removing unit 34 to the standby position farthest from the end point position T2, as shown in FIG. 17B. Further, the gear 26 is rotated in the positive direction (counterclockwise in FIG. 4) from the state shown in FIG. As a result, the air filter 18 is conveyed from the first holding space 20A to the second holding space 20B. When the tip of the air filter 18 passes between the brush holding portion 32 and the shaft 24, the brush holding portion 32 rotates in the forward direction (counterclockwise in FIG. 4) or in the reverse direction (clockwise in FIG. 4). The tip of the brush 30 comes into contact with the tip of the air filter 18 so as to straddle the net portion.
　ギヤ２６が更に正方向に回転されると、エアフィルタ１８が更に第２保持空間２０Ｂへと搬送される。この搬送の間、ブラシ保持部３２は、図３に示すように、ブラシ３０をエアフィルタ１８と接触する位置で固定する。これにより、エアフィルタ１８に付着した塵埃は、定位置で固定されるブラシ３０で堰き止められ、ブラシ３０のエアフィルタ１８の搬送方向の上流側に溜められる。このとき、ブラシ３０に溜められた塵埃とエアフィルタ１８に付着した塵埃とが絡み合って紙縒のように纏まる。これにより、エアフィルタ１８に付着した塵埃を除去することができる。ブラシ３０に付着した塵埃の一部は、塵埃受け部４０の内底面４０ｃ上に落ちる。 When the gear 26 is further rotated in the positive direction, the air filter 18 is further conveyed to the second holding space 20B. During this transfer, the brush holding portion 32 fixes the brush 30 at a position where it comes into contact with the air filter 18, as shown in FIG. As a result, the dust adhering to the air filter 18 is blocked by the brush 30 fixed at a fixed position, and is collected on the upstream side of the brush 30 in the transport direction of the air filter 18. At this time, the dust collected in the brush 30 and the dust adhering to the air filter 18 are entangled and gathered like a paper twist. As a result, the dust adhering to the air filter 18 can be removed. A part of the dust adhering to the brush 30 falls on the inner bottom surface 40c of the dust receiving portion 40.
　ギヤ２６が更に正方向に回転され、エアフィルタ１８が第２保持空間２０Ｂに到達すると、ギヤ２６の正方向の回転が停止される。このとき、ブラシ３０の先端部の少なくとも一部は、エアフィルタ１８の清掃領域外にあるエアフィルタ１８の後端部（枠体部分）に接触した状態にある。 When the gear 26 is further rotated in the positive direction and the air filter 18 reaches the second holding space 20B, the rotation of the gear 26 in the positive direction is stopped. At this time, at least a part of the tip portion of the brush 30 is in contact with the rear end portion (frame body portion) of the air filter 18 outside the cleaning area of the air filter 18.
　その後、ブラシ保持部３２が正方向（図３では反時計回り）に回転され、図５Ｂに示すように、ブラシ３０が塵埃除去部３４の前方ブレード３４ａ及び後方ブレード３４ｂに接触可能な位置に移動する。 After that, the brush holding portion 32 is rotated in the forward direction (counterclockwise in FIG. 3), and as shown in FIG. 5B, the brush 30 moves to a position where it can contact the front blade 34a and the rear blade 34b of the dust removing portion 34. To do.
　その後、図１７Ｃ及び図１７Ｄに示すように、制御部８０は、塵埃除去部３４を端点位置Ｔ２に近づくように移動させる。これにより、ブラシ３０に付着した塵埃が前方ブレード３４ａ及び後方ブレード３４ｂにより、塵埃受け部４０へ掻き落とされる。 After that, as shown in FIGS. 17C and 17D, the control unit 80 moves the dust removing unit 34 so as to approach the end point position T2. As a result, the dust adhering to the brush 30 is scraped off by the front blade 34a and the rear blade 34b to the dust receiving portion 40.
　また、制御部８０は、塵埃除去部３４が端点位置Ｔ２まで移動した後、塵埃除去部３４を再度待機位置まで移動させてもよい。これにより、ブラシ３０に取り残された塵埃を掻き落とすことができる。さらに、上述したような往復動作が複数回繰り返されることによって、ブラシ３０に取り残された塵埃を完全に塵埃受け部４０へ掻き落とすことができる。 Further, the control unit 80 may move the dust removing unit 34 to the standby position again after the dust removing unit 34 has moved to the end point position T2. As a result, the dust left behind on the brush 30 can be scraped off. Further, by repeating the reciprocating operation as described above a plurality of times, the dust left behind by the brush 30 can be completely scraped off to the dust receiving portion 40.
　また、上述したように、制御部８０は、塵埃除去部３４の動作中、ブラシ３０を図５Ａから図５Ｃに示したように、常時揺動させてもよい。これにより、ブラシ３０から掻き取られた塵埃の塊が過剰に大きくなる前に、塵埃受け部４０の内底面４０ｃへ均等に掻き落とすことができる。 Further, as described above, the control unit 80 may constantly swing the brush 30 during the operation of the dust removing unit 34, as shown in FIGS. 5A to 5C. As a result, the dust lumps scraped from the brush 30 can be evenly scraped off to the inner bottom surface 40c of the dust receiving portion 40 before becoming excessively large.

　以上のように、本出願において開示する技術の例示として、実施の形態１を説明したが、これに限られない。また、上記実施の形態１で説明した構成要素と組み合わせて、新たな実施の形態とすることが可能である。 (Other embodiments)
As described above, the first embodiment has been described as an example of the technology disclosed in the present application, but the present invention is not limited to this. In addition, it is possible to form a new embodiment by combining with the components described in the first embodiment.
　実施の形態１では、ブラシ３０は、ブラシ３０の延在方向と交差する方向に揺動するように構成されているが、本開示はこれに限定されない。すなわち、ブラシ３０は、必ずしもブラシ３０の延在方向と交差する方向に揺動するように構成されなくてもよい。 In the first embodiment, the brush 30 is configured to swing in a direction intersecting the extending direction of the brush 30, but the present disclosure is not limited to this. That is, the brush 30 does not necessarily have to be configured to swing in a direction intersecting the extending direction of the brush 30.
　実施の形態１では、塵埃除去部３４は、ブラシ３０の延在方向に対して交差する方向に延在する前方ブレード３４ａ及び後方ブレード３４ｂを有するとしたが、本開示はこれに限定されない。例えば、塵埃除去部３４は、ブラシ３０の延在方向に対して交差する方向に延在する１つのブレード又は３つ以上のブレードを有してもよい。 In the first embodiment, the dust removing unit 34 has a front blade 34a and a rear blade 34b extending in a direction intersecting the extending direction of the brush 30, but the present disclosure is not limited to this. For example, the dust removing unit 34 may have one blade or three or more blades extending in a direction intersecting the extending direction of the brush 30.
　また、実施の形態１では、塵埃除去部３４は、前方ブレード３４ａ、後方ブレード３４ｂ、及び側方ブレード３４ｅ，３４ｆにより、ブラシ３０に付着した塵埃を掻き落とすように構成されているが、本開示はこれに限定されない。例えば、塵埃除去部３４は、エチケットブラシ（登録商標）のような他の構造により、ブラシ３０に付着した塵埃を掻き落とすように構成されてもよい。 Further, in the first embodiment, the dust removing unit 34 is configured to scrape off the dust adhering to the brush 30 by the front blade 34a, the rear blade 34b, and the side blades 34e and 34f. Is not limited to this. For example, the dust removing unit 34 may be configured to scrape off the dust adhering to the brush 30 by another structure such as an etiquette brush (registered trademark).
　また、実施の形態１では、塵埃除去部３４が吸引装置４２（吸引装置４２の近傍を含む）まで移動された後、塵埃の塊が吸引装置４２により吸引されるように構成したが、本開示はこれに限定されない。例えば、制御部８０は、塵埃除去部３４を吸引装置４２(吸引装置４２の近傍を含む）まで移動させた後、塵埃除去部３４を吸引装置４２から例えば数ｃｍ程度離れるように移動させ、その後、塵埃の塊を吸引装置４２により吸引するように制御してもよい。塵埃除去部３４を吸引装置４２から離すことで、塵埃除去部３４の押圧面３４ｈと塵埃受け部４０の内側面とに挟まれた塵埃の塊が塵埃受け部４０の内底面４０ｃ上に落ち易くなる。これにより、吸引装置４２が塵埃を吸引しやすくなり、塵埃の除去効率が一層向上する。 Further, in the first embodiment, the dust removing unit 34 is moved to the suction device 42 (including the vicinity of the suction device 42), and then the dust mass is sucked by the suction device 42.
