空気調和機Air conditioner
　本発明は、エアフィルタに付着した塵埃を清掃するフィルタ清掃装置を備える空気調和機に関する。 The present invention relates to an air conditioner provided with a filter cleaning device for cleaning dust adhering to an air filter.

　特許文献１の空気調和機においては、ブレードに付着した塵埃をブラシにより掻き落とし、掻き落とした塵埃を塵埃受け部が受け取る構成であるが、ブレードからの塵埃の掻き落としが効率的ではなく、塵埃の除去効率を向上させるという観点において、未だ改善の余地があった。また、特許文献１の空気調和機は、ブレードから塵埃受け部に掻き落とされた塵埃を吸引装置の駆動によって生じる気流により排出管路を介して屋外に排出する構成であるため、塵埃を屋外に排出するための排出管路を室内と屋外との間の壁に貫設させる必要があった。しかしながら、空気調和機の設置環境においては、そのような排出管路を壁に貫設できない場合がある。そのような設置環境においても対応可能な空気調和機の構成が求められている。 In the air conditioner of Patent Document 1, the dust adhering to the blade is scraped off with a brush, and the dust receiving portion receives the scraped dust. However, scraping the dust from the blade is not efficient and the dust is dusted. There was still room for improvement in terms of improving the removal efficiency of the air conditioner. Further, since the air conditioner of Patent Document 1 has a configuration in which the dust scraped from the blade to the dust receiving portion is discharged to the outside through the discharge pipe by the air flow generated by driving the suction device, the dust is discharged outdoors. It was necessary to penetrate the discharge pipeline between the indoor and outdoor areas for discharge. However, in the installation environment of the air conditioner, it may not be possible to penetrate such a discharge pipe into the wall. There is a demand for a configuration of an air conditioner that can handle such an installation environment.

　ブラシ保持部３２は、その回転軸３２ａを中心として回動することにより、ブラシ３０の先端部を、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、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）とに配置する。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に付着した塵埃に対する除去動作においては、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」が、含まれる。また、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。「摺動掻き落とし動作」、「摺動掻き集め動作」、及び「揺動掻き落とし動作」の詳細については後述する。 The brush holding portion 32 rotates around the rotation shaft 32a so that the tip portion of the brush 30 is positioned downstream of the guide member 28 on the outward path (position on the right side of the lower end of the guide member 28 in FIG. 3). ), It is arranged at a first position (see FIG. 3) in contact with the air filter 18 existing in the second holding space 20B 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. In the removing operation for the dust adhering to the brush 30, 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 scraped up. "Sliding scraping operation" is included. Further, it may include a "swinging scraping operation" in which the brush 30 is swung to come into contact with the dust removing unit 34 to scrape off the dust of the brush 30. Details of the "sliding scraping operation", the "sliding scraping operation", and the "swing scraping operation" will be described later.
　塵埃除去部３４の下側には、塵埃除去部３４の下方を包むように、塵埃受け部４０が設けられている。塵埃受け部４０は、エアフィルタ１８からブラシ３０により掻き落とされた塵埃を受け取ると共に、ブラシ３０から塵埃除去部３４により掻き落とされた塵埃を受け取る構成である。塵埃受け部４０は、上面側が開放された細長い箱状に構成され、ブラシ３０の延在方向に沿って配設されている。塵埃除去部３４は、細長い箱状の塵埃受け部４０の内部をブラシ３０の延在方向に沿って移動（摺動）して、ブラシ３０に付着した塵埃を塵埃受け部４０に掻き落とし、塵埃受け部４０が受け取った塵埃を一方向に掻き集める構成である。 A dust receiving portion 40 is provided below the dust removing portion 34 so as to wrap the lower part of the dust removing portion 34. The dust receiving unit 40 is configured to receive the dust scraped off by the brush 30 from the air filter 18 and also receive the dust scraped off by the dust removing unit 34 from the brush 30. The dust receiving portion 40 is formed in an elongated box shape with the upper surface side open, and is arranged along the extending direction of the brush 30. The dust removing portion 34 moves (slides) inside the elongated box-shaped dust receiving portion 40 along the extending direction of the brush 30, scrapes the dust adhering to the brush 30 to the dust receiving portion 40, and dusts the dust. The structure is such that the dust received by the receiving unit 40 is collected in one direction.
　図５Ａ～図５Ｃ及び図６Ａ～図６Ｄは、ブラシ３０に付着した塵埃を塵埃除去部３４が掻き落とし、掻き集めるときの塵埃除去動作（「揺動掻き落とし動作」及び「摺動掻き集め動作」）を示す図である。図５Ａ～図５Ｃは、ブラシ３０の揺動動作により塵埃除去部３４がブラシ３０に付着した塵埃を掻き落とすときの「揺動掻き落とし動作」を模式的に示す拡大断面図である。図６Ａ～図６Ｄは、ブラシ３０の延在方向に沿って塵埃除去部３４が移動（摺動）する「摺動掻き落とし動作」及び／又は「摺動掻き集め動作」を示す正面図である。図６Ａ～図６Ｄにおいては、塵埃除去部３４の摺動（スライド動作）により塵埃除去部３４がブラシ３０に付着した塵埃を掻き落とすと共に、塵埃受け部４０に掻き落とされた塵埃を掻き集める様子を模式的に示している。 5A to 5C and 6A to 6D show a dust removing operation (“swing scraping operation” and “sliding scraping operation”” when the dust removing unit 34 scrapes and collects the dust adhering to the brush 30. ). 5A to 5C are enlarged cross-sectional views schematically showing a "swinging scraping operation" when the dust removing unit 34 scrapes off the dust adhering to the brush 30 by the swinging motion of the brush 30. 6A to 6D are front views showing a "sliding scraping operation" and / or a "sliding scraping operation" in which the dust removing portion 34 moves (slides) along the extending direction of the brush 30.

It is rubbed. In this way, the brush 30 swings in a direction intersecting the extending direction of the brush 30 (for example, in an orthogonal direction), so that the dust adhering to the brush 30 is scraped off by the dust removing unit 34. Specifically, as shown in FIGS. 5A to 5C, the tip portion of the brush 30 is configured to swing left and right with the downward position in contact with the dust removing portion 34 as the center position of the operation. By this swinging operation, the brush 30 comes into contact with the dust removing portion 34 so as to be rubbed against the dust removing portion 34, and the dust adhering to the brush 30 is scraped off by the dust removing portion 34. The dust scraped off by the dust removing unit 34 is received by the dust receiving unit 40 provided so as to wrap the dust removing unit 34 from below.
　塵埃除去部３４には、ブラシ３０に付着した塵埃を掻き落とすためのブレード部を有しており、実施形態１におけるブレード部には後述するように第１ブレード部（前方ブレード３４ａと後方ブレード３４ｂ）および第２ブレード部（側方ブレード３４ｅ、３４ｆ）を含んでいる。 The dust removing portion 34 has a blade portion for scraping off dust adhering to the brush 30, and the blade portion in the first embodiment has a first blade portion (front blade 34a and rear blade 34b) as described later. ) And the second blade portions ( side blades 34e, 34f) are included.
　塵埃除去部３４には、ブラシ３０が揺動するとき、ブラシ３０に付着した塵埃を掻き落とすための第２ブレード部を有しており、第２ブレード部は少なくとも１つの側方ブレード（３４ｅ、３４ｆ）を備えている。実施形態１における第２ブレード部は、ブラシ３０の延在方向と平行に延設され、互いに対向するように並設された２つの側方ブレード３４ｅ、３４ｆを含む。２つの側方ブレード３４ｅ、３４ｆの間となる後側空間Ｓ２は、ブラシ３０から側方ブレード３４ｅ、３４ｆにより掻き落とされた塵埃の多くが落ちていく空間となる。この「揺動掻き落とし動作」の詳細については後述する。 The dust removing portion 34 has a second blade portion for scraping off the dust adhering to the brush 30 when the brush 30 swings, and the second blade portion has at least one side blade (34e, 34f) is provided. The second blade portion in the first embodiment includes two side blades 34e and 34f extending parallel to the extending direction of the brush 30 and arranged side by side so as to face each other. The rear side space S2 between the two side blades 34e and 34f is a space where most of the dust scraped off by the side blades 34e and 34f from the brush 30 falls. The details of this "swinging scraping operation" will be described later.
　図６Ａ～図６Ｄに示すように、塵埃除去部３４が移動（摺動）する塵埃受け部４０における内底面４０ｃの左端には開口である吸引開口４０ｂが形成されている。この吸引開口４０ｂを覆うように塵埃受け部４０の左端側の下方には塵埃吸引部４８が設けられている。塵埃吸引部４８は塵埃受け部４０の左端側に突出するように形成されており、この突出端部には吸引穴４８ａが形成されている。塵埃吸引部４８の吸引穴４８ａは、本体２の左端側に設けられた後述する吸引装置４２（図７参照）に接続されており、吸引装置４２の動作により、塵埃吸引部４８の吸引穴４８ａを通して塵埃受け部４０の内部の空気が吸引される構成である。実施形態１においては、塵埃吸引部４８を設ける位置としては塵埃受け部４０の左端側の位置としたが、これは室内機１の左端側に塵埃吸引のための吸引源となる吸引装置４２を設けて、吸引装置４２と吸引穴４８ａとを繋ぐ吸引管４４の配管を考慮したためである。従って、塵埃吸引部４８を設ける位置としては、吸引装置４２の配設位置、塵埃受け部４０の形状、及び吸引管４４の配管の位置等が考慮されて適宜決定される。 As shown in FIGS. 6A to 6D, a suction opening 40b, which is an opening, is formed at the left end of the inner bottom surface 40c of the dust receiving portion 40 in which the dust removing portion 34 moves (slides).

In the first component (scraped component) 36, the first side wall 34c and the second side wall 34d project forward from the front blade 34a. Further, the front side edge portion from the front blade 34a to the first side wall 34c and the second side wall 34d on both sides has an edge shape (right angle or acute angle) and is formed so as to extend to the front side.
　上記のように、塵埃除去部３４においては、第１側壁３４ｃ及び第２側壁３４ｄが前方ブレード３４ａよりも前方側に突き出ており、第１側壁３４ｃと第２側壁３４ｄと前方ブレード３４ａとにより、前方空間Ｓ１の側方側及び後方側が区画されている。この前方空間Ｓ１には前方ブレード３４ａ等によりブラシ３０から掻き落とされた塵埃が落下することになる。このため、前方ブレード３４ａの縁部によりブラシ３０から掻き取った塵埃は、第１側壁３４ｃ及び第２側壁３４ｄにより案内されて、前方空間Ｓ１からはみ出すことが抑えられている。その結果、塵埃除去部３４の下側を包むように設けられた塵埃受け部４０においては、前方ブレード３４ａ等によりブラシ３０から掻き取った塵埃が前方空間Ｓ１を通り、塵埃受け部４０の内底面４０ｃ上に確実に落下する構成となっている。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としては、例えば、７ｍｍ以上である。 As described above, in the dust removing portion 34, the first side wall 34c and the second side wall 34d project forward from the front blade 34a, and the first side wall 34c, the second side wall 34d, and the front blade 34a The lateral side and the rear side of the front space S1 are partitioned. Dust scraped off from the brush 30 by the front blade 34a or the like falls into the front space S1. Therefore, the dust scraped from the brush 30 by the edge portion of the front blade 34a is guided by the first side wall 34c and the second side wall 34d, and is prevented from protruding from the front space S1. As a result, in the dust receiving portion 40 provided so as to wrap the lower side of the dust removing portion 34, the dust scraped from the brush 30 by the front blade 34a or the like passes through the front space S1 and the inner bottom surface 40c of the dust receiving portion 40 It is configured to surely fall up. 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。なお、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 shaft 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.
　上記のように構成された塵埃除去部３４の塵埃除去動作において、塵埃受け部４０の内部における前方側への摺動動作により前方ブレード３４ａ及び後方ブレード３４ｂがブラシ３０に付着した塵埃を掻き取って前方空間Ｓ１及び後方空間Ｓ２に塵埃を落下させる。また、摺動動作と同時に行われるブラシ３０の揺動動作においては、並設された第２ブレード部の側方ブレード３４ｅ、３４ｆによりブラシ３０に付着した塵埃が掻き取られて、掻き取られた塵埃は、後方空間Ｓ２等を落下する。後方空間Ｓ２に掻き落とされた塵埃は、後方空間Ｓ２の下方にある誘導面３４ｇにより前方空間Ｓ１側に案内されて塵埃受け部４０の内側底面である内底面４０ｃ上に落下する。なお、塵埃受け部４０の内底面４０ｃ上に落下する塵埃は、多くが塊となって落下し、内底面４０ｃにより確実に受け取られる。 In the dust removing operation of the dust removing unit 34 configured as described above, the front blade 34a and the rear blade 34b scrape off the dust adhering to the brush 30 by the sliding operation toward the front side inside the dust receiving unit 40. Dust is dropped into the front space S1 and the rear space S2. Further, in the swinging motion of the brush 30 performed at the same time as the sliding motion, the dust adhering to the brush 30 was scraped off by the side blades 34e and 34f of the second blade portion arranged side by side. Dust falls in the rear space S2 and the like. The dust scraped off in the rear space S2 is guided toward the front space S1 by the guide surface 34g below the rear space S2 and falls on the inner bottom surface 40c which is the inner bottom surface of the dust receiving portion 40. Most of the dust that falls on the inner bottom surface 40c of the dust receiving portion 40 falls in a lump and is reliably received by the inner bottom surface 40c.
　上記のように、第１ブレード部の前方ブレード３４ａと後方ブレード３４ｂ、及び第２ブレード部の側方ブレード３４ｅ、３４ｆによりブラシ３０から掻き取った塵埃の塊が後方空間Ｓ２に落下したとき、後方空間Ｓ２の下方に設けられた誘導面３４ｇにより確実に案内されて、塵埃受け部４０の内底面４０ｃに落下する。なお、第１ブレード部の並設された前方ブレード３４ａと後方ブレード３４ｂとの間隔、及び第２ブレード部の並設された側方ブレード３４ｅ、３４ｆの間隔は、各ブレードによりブラシ３０から掻き取った塵埃の塊が後方空間Ｓ２を通して確実に落下するように、例えば、１４ｍｍ以上に設計されている。第１ブレード部の前方ブレード３４ａと後方ブレード３４ｂ、及び第２ブレード部の側方ブレード３４ｅ、３４ｆは、塵埃の塊を掻き落とし易く、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。 As described above, when the dust mass scraped from the brush 30 by the front blade 34a and the rear blade 34b of the first blade portion and the side blades 34e and 34f of the second blade portion falls into the rear space S2, it is rearward. It is surely guided by the guide surface 34g provided below the space S2, and falls to the inner bottom surface 40c of the dust receiving portion 40. The distance between the front blades 34a and the rear blades 34b of the first blade portion and the distance between the side blades 34e and 34f of the second blade portion arranged side by side are scraped from the brush 30 by each blade. It is designed to be, for example, 14 mm or more so that a lump of dust can surely fall through the rear space S2. The front blade 34a and the rear blade 34b of the first blade portion, and the side blades 34e and 34f of the second blade portion are made of a material having excellent slidability, for example, polyacetal, which easily scrapes off dust lumps. ..
　塵埃除去部３４において、後方空間Ｓ２の下方に設けられ、前方空間Ｓ１側に案内する誘導面３４ｇは、前方側である吸引穴４０ｂ側が下方に傾斜する斜面で構成されている。誘導面３４ｇの形状としては、前方側が下方に傾斜して塵埃の塊が前方空間Ｓ１に滑り落ちる構成であればよく、平面又は曲面で構成されていればよい。誘導面３４ｇの水平面に対する傾斜角度としては、例えば、３０度以上４０度以下である。上記のように、塵埃除去部３４は、重力を利用して、誘導面３４ｇによってブラシ３０から掻き落とされた塵埃の塊を塵埃除去部３４よりも塵埃吸引部４８側、即ち前方側に誘導して、塵埃受け部４０の内底面４０ｃ上に落下させる構成である。 In the dust removing portion 34, the guide surface 34g provided below the rear space S2 and guiding to the front space S1 side is composed of a slope on which the suction hole 40b side, which is the front side, is inclined downward. The shape of the guide surface 34g may be a flat surface or a curved surface, as long as the front side is inclined downward and the dust mass slides down into the front space S1. 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. As described above, the dust removing unit 34 uses gravity to guide the dust mass scraped off from the brush 30 by the guiding surface 34g to the dust suction unit 48 side, that is, to the front side of the dust removing unit 34. Therefore, it is configured to be dropped onto the inner bottom surface 40c of the dust receiving portion 40.
　また、塵埃除去部３４には、塵埃除去部３４よりも前方側における塵埃受け部４０の内底面４０ｃ上の空間と、塵埃除去部３４の上部空間とを、前方空間Ｓ１及び後方空間Ｓ２を介して連通させる吸気穴３４ｉが形成されている。実施形態１における吸気穴３４ｉは、図８に示すように、塵埃除去部３４の第１部品（掻き落とし部品）３６における第２ブレード部の手前側の側方ブレード３４ｆの近傍に形成されており、側方ブレード３４ｆの縁部に沿った細長い貫通穴により構成される。実施形態１においては、第１ブレード部（前方ブレード３４ａ、後方ブレード３４ｂ）、第１側壁３４ｃ、第２側壁３４ｄ、第２ブレード部（奥側の側方ブレード３４ｅ、手前側の側方ブレード３４ｆ）、誘導面３４ｇ、及び吸気穴３４ｉが、第１部品（掻き落とし部品）３６に設けられている。 Further, in the dust removing portion 34, a space on the inner bottom surface 40c of the dust receiving portion 40 on the front side of the dust removing portion 34 and an upper space of the dust removing portion 34 are provided via the front space S1 and the rear space S2. Intake holes 34i are formed to communicate with each other. As shown in FIG. 8, the intake hole 34i in the first embodiment is formed in the vicinity of the side blade 34f on the front side of the second blade portion of the first component (scraping component) 36 of the dust removing portion 34. , Consists of elongated through holes along the edge of the lateral blade 34f. In the first embodiment, the first blade portion (front blade 34a, rear blade 34b), the first side wall 34c, the second side wall 34d, and the second blade portion (back side side blade 34e, front side side blade 34f). ), The guide surface 34g, and the intake hole 34i are provided in the first component (scraping component) 36.
　図９に示すように、上記のように構成された第１部品（掻き落とし部品）３６に対して、第２部品（掻き集め部品）３８が脱着可能に構成されている。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。また、第２部品３８には、第１部品３６との嵌合時に接触面となる嵌合面３４ｐが形成されている。この嵌合面３４ｐには摺動動作の方向と直交する方向に連続する凹凸面となっており、第１部品３６と第２部品３８との嵌合状態において互いの接触面が確実に接触し、がたつくことが無い構成となっている。上記のように構成された第１部品３６及び第２部品３８は、摺動動作の方向に直交する方向に抜き差し（スライド）して脱着可能な構成であり、ボルト７０により互いに固着されている。 As shown in FIG. 9, the second part (scraped part) 38 is detachably configured with respect to the first part (scraped part) 36 configured as described above. 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. Further, the second component 38 is formed with a fitting surface 34p that serves as a contact surface when mating with the first component 36. The fitting surface 34p has a concavo-convex surface that is continuous in a direction orthogonal to the direction of the sliding operation, and the contact surfaces of the first component 36 and the second component 38 are surely in contact with each other in the fitted state. , It has a structure that does not rattle. The first component 36 and the second component 38 configured as described above have a configuration in which they can be inserted and removed (sliding) in a direction orthogonal to the direction of the sliding operation, and are fixed to each other by bolts 70.
　塵埃除去部３４において、上記のように第１部品３６に対して脱着可能な第２部品３８には、第１部品３６の第１側壁３４ｃ及び第２側壁３４ｄに連続するように第３側壁３４ｑ及び第４側壁３４ｒが前方に突設されている。第３側壁３４ｑ及び第４側壁３４ｒは、第１側壁３４ｃ及び第２側壁３４ｄと協働して前方空間Ｓ１に掻き落とされた塵埃の塊を塵埃除去部３４の前方側に案内して、落下させている。この結果、塵埃除去部３４により掻き落とされた塵埃の塊が塵埃除去部３４の前方側の塵埃受け部４０の内底面４０ｃに確実に落下する構成となる。 In the dust removing unit 34, the second component 38, which is removable from the first component 36 as described above, has a third side wall 34q so as to be continuous with the first side wall 34c and the second side wall 34d of the first component 36. And the fourth side wall 34r is projected forward. The third side wall 34q and the fourth side wall 34r cooperate with the first side wall 34c and the second side wall 34d to guide the dust mass scraped off in the front space S1 to the front side of the dust removing portion 34 and fall. I'm letting you. As a result, the dust mass scraped off by the dust removing portion 34 is surely dropped onto the inner bottom surface 40c of the dust receiving portion 40 on the front side of the dust removing portion 34.
　また、塵埃除去部３４の第２部品（掻き集め部品）３８には、塵埃除去部３４が摺動動作（「摺動掻き集め動作」）を行うときに、塵埃受け部４０の内底面４０ｃにある塵埃の塊を掻き集めるための押圧面３４ｈが形成されている。押圧面３４ｈは、第３側壁３４ｑと第４側壁３４ｒとの間に形成されており、第１部品（掻き落とし部品）３６の誘導面３４ｇの下方の位置である。即ち、第２部品（掻き集め部品）３８の押圧面３４ｈは、塵埃除去部３４が塵埃吸引部４８側（左側）に摺動するとき、塵埃受け部４０に内部にある塵埃の塊を塵埃吸引部４８側に押圧して移動させる機能を有する。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。なお、実施形態１においては、押圧面３４ｈが鉛直面で構成されている。 Further, the second component (scraping component) 38 of the dust removing section 34 has dust on the inner bottom surface 40c of the dust receiving section 40 when the dust removing section 34 performs a sliding operation (“sliding scraping operation”). A pressing surface 34h for scraping the lumps of The pressing surface 34h is formed between the third side wall 34q and the fourth side wall 34r, and is located below the guide surface 34g of the first component (scraping component) 36. That is, the pressing surface 34h of the second component (scraping component) 38 collects a lump of dust inside the dust receiving portion 40 when the dust removing portion 34 slides toward the dust suction portion 48 (left side). It has a function of pressing and moving to the 48 side. 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 configured as a vertical surface.
　上記のように構成された塵埃除去部３４は、塵埃受け部４０の内底面４０ｃに沿って移動（摺動動作）することにより、第１部品（掻き落とし部品）３６がブラシ３０に付着した塵埃を掻き落とし、第２部品（掻き集め部品）３８が塵埃受け部４０に内部の塵埃を塵埃吸引部４８側に掻き集める機能を有している。 The dust removing portion 34 configured as described above moves (sliding operation) along the inner bottom surface 40c of the dust receiving portion 40, so that the first component (scraping component) 36 adheres to the brush 30. The second component (scraping component) 38 has a function of scraping the internal dust into the dust receiving portion 40 toward the dust suction portion 48.
　［塵埃自動排出構成におけるフィルタ清掃動作］
　次に、エアフィルタ１８に付着した塵埃を屋外に自動的に排出するフィルタ清掃動作について説明する。なお、エアフィルタ１８に対するフィルタ清掃動作は、図示しない制御部の制御の下で行われる。 [Filter cleaning operation in automatic dust discharge configuration]
Next, a filter cleaning operation for automatically discharging the dust adhering to the air filter 18 to the outside will be described. The filter cleaning operation for the air filter 18 is performed under the control of a control unit (not shown).
　エアフィルタ１８に対するフィルタ清掃動作の前においては、塵埃除去部３４が塵埃受け部４０の内部の左端位置（初期位置）に位置する（図６Ａ参照）。塵埃除去部３４が初期位置に配置された状態において、空調運転時間が所定時間経過したとき、又は図示しないコントローラが使用者に操作されてエアフィルタ１８に対するフィルタ清掃指示が入力されたとき、図６Ｂに示したように、塵埃除去部３４は、塵埃受け部４０の左端側に形成された吸引開口４０ｂから最も離れた右端位置である退避位置に移動する。塵埃除去部３４が退避位置に移動したとき、前述のように、フィルタ搬送装置２２のギヤ２６が正方向（図２では反時計回り）に回転して、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。 Before the filter cleaning operation for the air filter 18, the dust removing portion 34 is located at the left end position (initial position) inside the dust receiving portion 40 (see FIG. 6A). When the air conditioning operation time elapses for a predetermined time in the state where the dust removing unit 34 is arranged at the initial position, or when a controller (not shown) is operated by the user and a filter cleaning instruction for the air filter 18 is input, FIG. 6B As shown in the above, the dust removing portion 34 moves to the retracted position which is the farthest right end position from the suction opening 40b formed on the left end side of the dust receiving portion 40. When the dust removing unit 34 moves to the retracted position, as described above, the gear 26 of the filter transport device 22 rotates in the forward direction (counterclockwise in FIG. 2), and the air filter 18 moves from the first holding space 20A. It is conveyed to the second holding space 20B.
　上記のようにエアフィルタ１８が第１保持空間２０Ａから第２保持空間２０Ｂへ搬送されて、エアフィルタ１８の前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が回動して、ブラシ３０の先端部がエアフィルタ１８の先端部に接触する。 When the air filter 18 is conveyed from the first holding space 20A to the second holding space 20B as described above and the front end portion of the air filter 18 passes between the brush holding portion 32 and the shaft 24, the brush holding portion 32 Rotates, and the tip of the brush 30 comes into contact with the tip of the air filter 18.
　フィルタ搬送装置２２のギヤ２６が更に正方向に回転されて、エアフィルタ１８が更に第２保持空間２０Ｂへ搬送されるとき、ブラシ保持部３２は、図３に示したように、ブラシ３０の先端部がエアフィルタ１８と接触する位置で固定される。この結果、エアフィルタ１８に付着した塵埃は、所定位置に固定されたブラシ３０の先端部で堰き止められ、エアフィルタ１８の搬送方向におけるブラシ３０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搬送されるエアフィルタ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。このときブラシ３０に付着した塵埃の一部は、ブラシ３０の下方に配設された塵埃受け部４０の内底面４０ｃ上に直接掻き落とされる。なお、エアフィルタ１８に対するブラシ３０の押圧力を一定にするため、例えば、ブラシ３０にダンパーなどの弾性体を設けてもよい。これにより、エアフィルタ１８に付着した塵埃の除去効率がなお一層向上される。 When the gear 26 of the filter conveying device 22 is further rotated in the positive direction and the air filter 18 is further conveyed to the second holding space 20B, the brush holding portion 32 is the tip of the brush 30 as shown in FIG. The portion is fixed at a position where it comes into contact with the air filter 18. As a result, the dust adhering to the air filter 18 is blocked by the tip of the brush 30 fixed at a predetermined 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 to be conveyed are entangled and gathered like a paper twist. As a result, the dust adhering to the air filter 18 can be removed. At this time, a part of the dust adhering to the brush 30 is directly scraped off on the inner bottom surface 40c of the dust receiving portion 40 arranged below the brush 30. In order to keep the pressing force of the brush 30 on the air filter 18 constant, for example, the brush 30 may be provided with an elastic body such as a damper. As a result, the efficiency of removing dust adhering to the air filter 18 is further improved.
　フィルタ搬送装置２２のギヤ２６が更に正方向に回転して、エアフィルタ１８が第２保持空間２０Ｂに到達すると、ギヤ２６の正方向への回転は停止される。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 of the filter transfer device 22 further rotates 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.
　上記のようにエアフィルタ１８が第２保持空間２０Ｂに搬送されると、フィルタ搬送装置２２のギヤ２６が逆方向（図２では時計回り）に回転して、エアフィルタ１８が第２保持空間２０Ｂから第１保持空間２０Ａへ搬送される。この逆方向の搬送動作においても、エアフィルタ１８に付着している塵埃がブラシ３０により掻き落とされる構成としてもよい。 When the air filter 18 is conveyed to the second holding space 20B as described above, the gear 26 of the filter conveying device 22 rotates in the opposite direction (clockwise in FIG. 2), and the air filter 18 moves to the second holding space 20B. Is transported to the first holding space 20A. Even in this reverse transfer operation, the dust adhering to the air filter 18 may be scraped off by the brush 30.
　上記のようにエアフィルタ１８に付着していた塵埃がブラシ３０により掻き落とされた後、ブラシ保持部３２が正方向（図３では反時計回り）に回転して、塵埃除去部３４に接触可能な第２の位置（図４参照）に配置される。即ち、ブラシ３０は第２の位置において揺動動作を行い、ブラシ３０が塵埃除去部３４における第１ブレード部（前方ブレード３４ａ、後方ブレード３４ｂ）、及び第２ブレード部（側方ブレード３４ｅ、３４ｆ）等に接触して、主として第２ブレード部の側方ブレード３４ｅ、３４ｆによりブラシ３０に付着した塵埃が除去される。 After the dust adhering to the air filter 18 is scraped off by the brush 30 as described above, the brush holding portion 32 rotates in the forward direction (counterclockwise in FIG. 3) and can come into contact with the dust removing portion 34. It is arranged in a second position (see FIG. 4). That is, the brush 30 swings at the second position, and the brush 30 swings the first blade portion (front blade 34a, rear blade 34b) and the second blade portion ( side blades 34e, 34f) of the dust removing portion 34. ) And the like, and the dust adhering to the brush 30 is mainly removed by the side blades 34e and 34f of the second blade portion.
　また、図６Ｂ～図６Ｄに示したように、塵埃除去部３４は、吸引装置４２に接続された塵埃吸引部４８に近づくように左方向に移動（摺動）する。この左方向への摺動動作により、ブラシ３０に付着した塵埃が第１ブレード部の前方ブレード３４ａと後方ブレード３４ｂ、及び第２ブレード部の側方ブレード３４ｅ、３４ｆ等により、主として前方ブレード３４ａ及び後方ブレード３４ｂにより掻き落とされる。前方ブレード３４ａ及び後方ブレード３４ｂ等により掻き落とされた塵埃は、前方空間Ｓ１及び後方空間Ｓ２を介して、塵埃受け部４０の内底面４０ｃ上に落下する。このとき、後方空間Ｓ２を落下する塵埃の塊は、誘導面３４ｇにより案内されて、塵埃除去部３４よりも前方側である塵埃吸引部４８側に確実に落下する。このように、塵埃受け部４０の内底面４０ｃへ誘導された塵埃の塊は、塵埃除去部３４により塵埃吸引部４８側に落とされる。この結果、塵埃除去部３４が塵埃吸引部４８側へ移動（左方向への摺動動作）することにより、塵埃受け部４０の内底面４０ｃ上の塵埃の塊は、塵埃除去部３４の押圧面３４ｈによって吸引開口４０ｂに掻き集められて、塵埃吸引部４８に落とされる。塵埃除去部３４の移動速度は、例えば、５ｍｍ／秒である。 Further, as shown in FIGS. 6B to 6D, the dust removing unit 34 moves (slides) to the left so as to approach the dust suction unit 48 connected to the suction device 42. Due to this sliding operation to the left, dust adhering to the brush 30 is mainly caused by the front blades 34a and the rear blades 34b of the first blade portion, and the side blades 34e and 34f of the second blade portion, and the front blades 34a and 34f. It is scraped off by the rear blade 34b. The dust scraped off by the front blade 34a, the rear blade 34b, and the like falls onto the inner bottom surface 40c of the dust receiving portion 40 via the front space S1 and the rear space S2. At this time, the dust mass falling in the rear space S2 is guided by the guide surface 34g and surely falls to the dust suction unit 48 side, which is on the front side of the dust removing unit 34. In this way, the dust mass guided to the inner bottom surface 40c of the dust receiving portion 40 is dropped toward the dust suction portion 48 by the dust removing portion 34. As a result, the dust removing portion 34 moves toward the dust sucking portion 48 (sliding operation to the left), so that the dust mass on the inner bottom surface 40c of the dust receiving portion 40 becomes the pressing surface of the dust removing portion 34. It is scraped into the suction opening 40b by 34h and dropped into the dust suction unit 48. The moving speed of the dust removing unit 34 is, for example, 5 mm / sec.
　また、塵埃除去部３４の左方向への移動において、ブラシ保持部３２が回転軸３２ａを中心として正回転及び逆回転する揺動動作が複数回行われている。このように、ブラシ３０が延在方向と交差する方向に複数回揺動することにより、ブラシ３０から掻き取った塵埃の塊が過剰に大きくなる前に、第２ブレード部の側方ブレード３４ｅ、３４ｆ等によって塵埃受け部４０の内底面４０ｃ上に掻き落とされる。 Further, in the movement of the dust removing portion 34 to the left, the brush holding portion 32 is rotated forward and backward about the rotation shaft 32a a plurality of times. By swinging the brush 30 a plurality of times in the direction intersecting the extending direction in this way, the side blades 34e of the second blade portion, before the mass of dust scraped from the brush 30 becomes excessively large, It is scraped off on the inner bottom surface 40c of the dust receiving portion 40 by 34f or the like.
　図６Ｄに示すように、塵埃除去部３４が吸引開口４０ｂの近傍（塵埃排出位置）まで移動されると、吸引装置４２の吸引ファン４６が駆動され、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によって吸引開口４０ｂの近傍に集められ、塵埃吸引部４８に落とされた塵埃の塊が吸引管４４を通じて屋外に排出される。 As shown in FIG. 6D, when the dust removing unit 34 is moved to the vicinity of the suction opening 40b (dust discharge position), the suction fan 46 of the suction device 42 is driven, and an air flow that becomes a suction force is generated in the suction pipe 44. appear. Due to this air flow, the dust lumps collected in the vicinity of the suction opening 40b by the pressing surface 34h of the dust removing portion 34 and dropped on the dust suction portion 48 are discharged to the outside through the suction pipe 44.
　上記のようにブラシ３０に対する塵埃除去動作における１回目の「塵埃排出動作」が終了する。「塵埃排出動作」が終了した後、塵埃除去部３４が吸引開口４０ｂから最も離れた右端の退避位置へ再度移動される（図６Ｂ参照）。このときの塵埃除去部３４の右方向への移動において、後述するように、塵埃受け部４０の内底面４０ｃ上に残っている塵埃が右方向に移動することが抑制されている。即ち、塵埃除去部３４の底面及び塵埃受け部４０の内底面が塵埃の移動を一方向に規制する構成（塵埃移動方向規制構成）を有している。従って、塵埃受け部４０の内底面４０ｃ上にある塵埃の塊は、右方向にほとんど移動させられることがなく、落下した位置にそのまま保持されている。その結果、塵埃除去部３４が右端の退避位置に移動したとき、塵埃受け部４０の内底面４０ｃ上にある塵埃の塊は、塵埃除去部３４の第２部品（掻き集め部品）における押圧面３４ｈより左側の位置である、塵埃受け部４０の吸引開口４０ｂ側の位置に存在することになる。 As described above, the first "dust discharge operation" in the dust removal operation for the brush 30 is completed. After the "dust discharge operation" is completed, the dust removing unit 34 is moved again to the rightmost retracted position farthest from the suction opening 40b (see FIG. 6B). In the movement of the dust removing portion 34 to the right at this time, as will be described later, the dust remaining on the inner bottom surface 40c of the dust receiving portion 40 is suppressed from moving to the right. That is, the bottom surface of the dust removing portion 34 and the inner bottom surface of the dust receiving portion 40 have a configuration that regulates the movement of dust in one direction (dust movement direction regulating configuration). Therefore, the dust mass on the inner bottom surface 40c of the dust receiving portion 40 is hardly moved to the right and is held as it is at the dropped position. As a result, when the dust removing portion 34 is moved to the rightmost retracted position, the dust mass on the inner bottom surface 40c of the dust receiving portion 40 is removed from the pressing surface 34h of the second component (scraping component) of the dust removing portion 34. It is located on the left side, which is the position on the suction opening 40b side of the dust receiving portion 40.
　その後、図６Ｃ及び図６Ｄに示すように、塵埃除去部３４が吸引開口４０ｂ側へ再度移動（摺動動作）する。これにより、塵埃受け部４０の内底面４０ｃ上にある塵埃の塊が、塵埃除去部３４の第２部品（掻き集め部品）における押圧面３４ｈによって吸引開口４０ｂに向けて押されていく。 After that, as shown in FIGS. 6C and 6D, the dust removing portion 34 moves (sliding operation) again to the suction opening 40b side. As a result, the dust mass on the inner bottom surface 40c of the dust receiving portion 40 is pushed toward the suction opening 40b by the pressing surface 34h of the second component (scraping component) of the dust removing portion 34.
　図６Ｄに示したように、塵埃除去部３４が吸引開口４０ｂの近傍の位置（塵埃排出位置）まで移動すると、吸引装置４２の吸引ファン４６が駆動され、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によって吸引開口４０ｂの近傍に集められ、塵埃吸引部４８に落とされた塵埃の塊が吸引管４４を通じて屋外に排出される。なお、この塵埃除去部３４の摺動動作及び吸引装置４２による吸引動作を伴う「塵埃排出動作」は、複数回行われてもよい。このように「塵埃排出動作」が行われて、エアフィルタ１８の清掃動作が完了する。 As shown in FIG. 6D, when the dust removing unit 34 moves to a position near the suction opening 40b (dust discharge position), the suction fan 46 of the suction device 42 is driven, and an air flow that becomes a suction force in the suction pipe 44. Occurs. Due to this air flow, the dust lumps collected in the vicinity of the suction opening 40b by the pressing surface 34h of the dust removing portion 34 and dropped on the dust suction portion 48 are discharged to the outside through the suction pipe 44. The "dust discharge operation" accompanied by the sliding operation of the dust removing unit 34 and the suction operation by the suction device 42 may be performed a plurality of times. In this way, the "dust discharge operation" is performed, and the cleaning operation of the air filter 18 is completed.
　なお、上記のように、ブラシ３０に付着した塵埃に対する一連の「揺動掻き落とし動作」、「摺動掻き落とし動作」、「摺動掻き集め動作」、及び「塵埃排出動作」は少なくとも１回、若しくは連続して複数回行ってもよい。また、本発明の空気調和機においては、「揺動掻き落とし動作」、「摺動掻き落とし動作」、及び「摺動掻き集め動作」を連続して、又はこれらの動作を状況に応じて選択的に行う構成としてもよい。「塵埃排出動作」は「摺動掻き集め動作」の後に実行するよう構成することが好ましい。 As described above, a series of "swing scraping operation", "sliding scraping operation", "sliding scraping operation", and "dust discharge operation" for dust adhering to the brush 30 are performed at least once. Alternatively, it may be performed a plurality of times in succession. Further, in the air conditioner of the present invention, the "swing scraping operation", the "sliding scraping operation", and the "sliding scraping operation" are continuously performed, or these operations are selectively selected according to the situation. It may be configured to be performed in. It is preferable that the "dust discharge operation" is executed after the "sliding scraping operation".
　実施形態１に係る空気調和機によれば、塵埃除去部３４がブラシ３０に接触しつつブラシ３０の延在方向に移動（摺動動作）することによって、ブラシ３０に付着した塵埃同士が絡み合って纏まり易くなり、従来よりも塵埃の除去効率を向上させることができる。また、ブラシ３０と塵埃除去部３４との接触部分が小さく、塵埃除去部３４がブラシ３０から受ける接触圧を小さくすることができるので、塵埃除去部３４を摺動動作させるための駆動力を小さくすることができる。さらに、塵埃除去部３４自体の形状が小さく、軽量化が図られているため、塵埃除去部３４のための駆動力を小さくすることができる。 According to the air conditioner according to the first embodiment, the dust removing unit 34 moves (sliding) in the extending direction of the brush 30 while being in contact with the brush 30, so that the dust adhering to the brush 30 is entangled with each other. It becomes easier to collect and the dust removal efficiency can be improved as compared with the conventional case. Further, since the contact portion between the brush 30 and the dust removing portion 34 is small and the contact pressure received by the dust removing portion 34 from the brush 30 can be reduced, the driving force for sliding the dust removing portion 34 is reduced. can do. Further, since the shape of the dust removing unit 34 itself is small and the weight is reduced, the driving force for the dust removing unit 34 can be reduced.
　実施形態１の構成においては、塵埃除去部３４を塵埃受け部４０の吸引開口４０ｂの近傍位置（塵埃排出位置）まで移動させた後、塵埃を吸引装置４２により吸引するように構成したが、本発明はこれに限定されない。例えば、塵埃除去部３４を吸引開口４０ｂの近傍位置まで移動させた後、塵埃除去部３４を吸引開口４０ｂから、例えば数ｃｍ程度後方に離れるように移動させ、その後、塵埃受け部４０の内部の塵埃を吸引装置４２により吸引するように構成してもよい。このように構成して、吸引時に塵埃除去部３４を吸引開口４０ｂから一旦離すことにより、塵埃除去部３４の押圧面３４ｈと塵埃受け部４０の内側面との間に挟まれた塵埃の塊が塵埃受け部４０の内底面４０ｃ上に落ちるきっかけを与えることができる。これにより、吸引装置４２による吸引動作により塵埃受け部４０の内部の塵埃をきれいに吸引しやすくなり、塵埃の除去効率を一層向上させることができる。 In the configuration of the first embodiment, the dust removing portion 34 is moved to a position (dust discharge position) near the suction opening 40b of the dust receiving portion 40, and then the dust is sucked by the suction device 42. The invention is not limited to this. For example, after moving the dust removing portion 34 to a position near the suction opening 40b, the dust removing portion 34 is moved away from the suction opening 40b by, for example, about several cm, and then inside the dust receiving portion 40. The dust may be sucked by the suction device 42. With this configuration, by temporarily separating the dust removing portion 34 from the suction opening 40b during suction, a lump of dust sandwiched between the pressing surface 34h of the dust removing portion 34 and the inner surface of the dust receiving portion 40 is formed. It is possible to give a trigger to fall on the inner bottom surface 40c of the dust receiving portion 40. As a result, the suction operation by the suction device 42 makes it easier to cleanly suck the dust inside the dust receiving portion 40, and the dust removal efficiency can be further improved.
［塵埃除去部の駆動機構］
　図１２は、実施形態１に係る空気調和機における塵埃除去部３４の駆動機構の構成例を示す図である。図１２においては、第１部品（掻き落とし部品）３６と第２部品（掻き集め部品）３８とを有する塵埃自動排出構成の塵埃除去部３４に対する駆動機構を示している。但し、塵埃除去部３４において第２部品（掻き集め部品）３８が取り外され、第１部品（掻き落とし部品）３６のみを有する後述する塵埃手動排出構成の塵埃除去部３４に対する駆動機構も同じ構成である。 [Drive mechanism of dust remover]
FIG. 12 is a diagram showing a configuration example of a drive mechanism of the dust removing unit 34 in the air conditioner according to the first embodiment. FIG. 12 shows a drive mechanism for a dust removing unit 34 having an automatic dust discharging configuration having a first component (scraping component) 36 and a second component (scraping component) 38. However, the second component (scraping component) 38 is removed from the dust removing section 34, and the drive mechanism for the dust removing section 34 of the dust removing configuration described later, which has only the first component (scraping component) 36, has the same configuration. ..
　図１２に示すように、実施形態１に係る空気調和機は、塵埃除去部３４をブラシ３０の延在方向に移動（摺動動作）させるための駆動装置５０を備えている。図１２に示す構成例において、駆動装置５０は、駆動プーリ５２と、従動プーリ５４と、駆動プーリ５２及び従動プーリ５４の周囲に架け回されたワイヤ５６と、駆動プーリ５２を回転させるモータ５８と、ワイヤ５６に取り付けられた駆動ブロック６０とを備えている。駆動ブロック６０には塵埃除去部３４が固定されており、駆動ブロック６０の移動と共に塵埃除去部３４が摺動動作する構成である。 As shown in FIG. 12, the air conditioner according to the first embodiment includes a drive device 50 for moving (sliding) the dust removing unit 34 in the extending direction of the brush 30. In the configuration example shown in FIG. 12, the drive device 50 includes a drive pulley 52, a driven pulley 54, a wire 56 laid around the drive pulley 52 and the driven pulley 54, and a motor 58 for rotating the drive pulley 52. , A drive block 60 attached to a wire 56. A dust removing unit 34 is fixed to the drive block 60, and the dust removing unit 34 slides as the drive block 60 moves.
　駆動装置５０においては、モータ５８が回転駆動されることにより、駆動プーリ５２が回転してワイヤ５６を移動させて、従動プーリ５４が回転する。これにより、駆動ブロック６０が駆動プーリ５２と従動プーリ５４との間を移動することができる。塵埃除去部３４の駆動装置５０は、本体２の内部において、例えば、塵埃受け部４０の背面側に設けられたカバー部材６２に設けられている。カバー部材６２は、例えば、平板であり、ブラシ３０の延在方向（図１２では左右方向）に沿って設けられている。カバー部材６２を間にして、一方に駆動装置５０が設けられ、他方に塵埃除去部３４及び塵埃受け部４０が設けられている。 In the drive device 50, when the motor 58 is rotationally driven, the drive pulley 52 rotates to move the wire 56, and the driven pulley 54 rotates. As a result, the drive block 60 can move between the drive pulley 52 and the driven pulley 54. The drive device 50 of the dust removing unit 34 is provided inside the main body 2, for example, on a cover member 62 provided on the back side of the dust receiving unit 40. The cover member 62 is, for example, a flat plate, and is provided along the extending direction (left-right direction in FIG. 12) of the brush 30. A drive device 50 is provided on one side of the cover member 62, and a dust removing portion 34 and a dust receiving portion 40 are provided on the other side.
　図１３は、駆動装置５０の駆動ブロック６０と、塵埃除去部３４との配置を示す斜視図である。図１４は、塵埃受け部４０の内部に設けられた塵埃除去部３４と、駆動装置５０の駆動ブロック６０とを示す断面図である。図１３及び図１４においても、塵埃自動排出構成の塵埃除去部３４を示している。 FIG. 13 is a perspective view showing the arrangement of the drive block 60 of the drive device 50 and the dust removing unit 34. FIG. 14 is a cross-sectional view showing a dust removing portion 34 provided inside the dust receiving portion 40 and a drive block 60 of the drive device 50. 13 and 14 also show a dust removing unit 34 having an automatic dust discharging configuration.
　図１３及び図１４に示すように、駆動ブロック６０からカバー部材６２を乗り越えるように延びる駆動ブロック接合部６０ａが塵埃除去部３４の第１側壁３４ｃに接合されている。実施形態１の構成においては、第１側壁３４ｃの上部に形成された凹部に駆動ブロック接合部６０ａの端部が嵌合して固着される構成である。また、駆動ブロック接合部６０ａは、平板のカバー部材６２の上辺部分を跨ぐように配設されている。この結果、駆動ブロック６０の移動に伴い、塵埃除去部３４がカバー部材６２に沿って移動する構成となる。カバー部材６２の延在方向は、ブラシ３０の延在方向と実質的に同じであるため、塵埃除去部３４はブラシ３０の延在方向に沿って移動（摺動動作）する。 As shown in FIGS. 13 and 14, a drive block joint portion 60a extending from the drive block 60 so as to get over the cover member 62 is joined to the first side wall 34c of the dust removing portion 34. In the configuration of the first embodiment, the end portion of the drive block joint portion 60a is fitted and fixed to the recess formed in the upper portion of the first side wall 34c. Further, the drive block joint portion 60a is arranged so as to straddle the upper side portion of the flat plate cover member 62. As a result, as the drive block 60 moves, the dust removing portion 34 moves along the cover member 62. Since the extending direction of the cover member 62 is substantially the same as the extending direction of the brush 30, the dust removing portion 34 moves (sliding operation) along the extending direction of the brush 30.
　上記のように、塵埃除去部３４の第１側壁３４ｃの上部に駆動ブロック接合部６０ａの端部が嵌合されており、塵埃除去部３４における第２ブレード部のカバー部材６２側の側方ブレード３４ｅからカバー部材６２側へは、滑らかに上昇する面で構成されている。このように、第１側壁３４ｃの上部に駆動ブロック接合部６０ａの端部が固着されており、第２ブレード部のカバー部材６２側の側方ブレード３４ｅより高い位置に駆動ブロック接合部６０ａが設けられている。このため、駆動ブロック接合部６０ａ及びカバー部材６２によって、塵埃除去部３４によりブラシ３０から掻き落とされた塵埃がカバー部材６２を乗り越えて駆動装置５０側に侵入することを抑えられている。その結果、実施形態１に係る空気調和機においては、塵埃の除去効率を一層向上させることができる。 As described above, the end of the drive block joint 60a is fitted to the upper portion of the first side wall 34c of the dust removing portion 34, and the side blade of the second blade portion of the dust removing portion 34 on the cover member 62 side. From 34e to the cover member 62 side, a surface that rises smoothly is formed. As described above, the end portion of the drive block joint portion 60a is fixed to the upper portion of the first side wall 34c, and the drive block joint portion 60a is provided at a position higher than the side blade 34e on the cover member 62 side of the second blade portion. Has been done. Therefore, the drive block joint portion 60a and the cover member 62 prevent dust scraped from the brush 30 by the dust removing portion 34 from passing over the cover member 62 and entering the drive device 50 side. As a result, in the air conditioner according to the first embodiment, the dust removal efficiency can be further improved.
　また、実施形態１の構成において、塵埃除去部３４の吸気穴３４ｉは、図５Ａ～図５Ｃに示したように、第２ブレード部におけるカバー部材６２側（奥側）の側方ブレード３４ｅとは反対側であるカバー部材から離れた手前側の側方ブレード３４ｆの近傍に吸気穴３４ｉが形成されている。すなわち、第２側壁３４ｄ側に吸気穴３４ｉが形成されている。このように、吸気穴３４ｉをカバー部材６２から離して設けることにより、塵埃がカバー部材６２を乗り越えて駆動装置５０側に侵入することを一層抑えられる構成となっている。その結果、実施形態１に係る空気調和機においては、塵埃の除去効率を一層向上させることができる。 Further, in the configuration of the first embodiment, the intake hole 34i of the dust removing portion 34 is different from the side blade 34e on the cover member 62 side (back side) in the second blade portion, as shown in FIGS. 5A to 5C. An intake hole 34i is formed in the vicinity of the side blade 34f on the front side away from the cover member on the opposite side. That is, an intake hole 34i is formed on the second side wall 34d side. In this way, by providing the intake hole 34i away from the cover member 62, it is possible to further prevent dust from passing over the cover member 62 and entering the drive device 50 side. As a result, in the air conditioner according to the first embodiment, the dust removal efficiency can be further improved.
　実施形態１の構成においては、ブラシ３０に付着した塵埃に対する除去動作を行う場合、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しているが、ブラシ３０に付着した塵埃を除去する方法としては、例えばブラシ３０の長手方向の長さと同程度の長さのブレードをブラシ３０と平行に延在させて、ブラシ３０がそのブレードに接触する位置で揺動することにより、ブラシ３０に付着した塵埃を除去する方法であってもよい。また、ブラシ３０の形状としては、実施形態１の構成以外に、例えばローラー状のブラシであってもよい。 In the configuration of the first embodiment, when the dust adhering to the brush 30 is removed, the dust removing portion 34 is moved (sliding) along the extending direction of the brush 30 to scrape off the dust. As a method of removing dust adhering to the brush 30, for example, a blade having a length similar to the length in the longitudinal direction of the brush 30 is extended in parallel with the brush 30 at a position where the brush 30 comes into contact with the blade. A method of removing dust adhering to the brush 30 by swinging may be used. Further, the shape of the brush 30 may be, for example, a roller-shaped brush other than the configuration of the first embodiment.
　［塵埃除去部と塵埃受け部における塵埃移動方向規制構成］
　実施形態１に係る空気調和機における塵埃自動排出構成においては、塵埃除去部３４が塵埃受け部４０の内底面４０ｃに沿って移動（摺動動作）することにより、第１部品（掻き落とし部品）３６がブラシ３０に付着した塵埃を掻き落とし、第２部品（掻き集め部品）３８が塵埃受け部４０に内部の塵埃を塵埃吸引部４８側に掻き集める構成である。第２部品（掻き集め部品）３８が塵埃受け部４０に内底面４０ｃ上の塵埃を効率高く塵埃吸引部４８側に掻き集めることができるように、第２部品（掻き集め部品）３８の底面３４ｊ及び塵埃受け部４０に内底面４０ｃは、塵埃移動方向規制構成を有している。 [Dust movement direction regulation configuration in the dust removing part and dust receiving part]
In the dust automatic discharge configuration in the air conditioner according to the first embodiment, the dust removing portion 34 moves (sliding operation) along the inner bottom surface 40c of the dust receiving portion 40, so that the first component (scraping component) is used. The 36 scrapes off the dust adhering to the brush 30, and the second component (scraping component) 38 scrapes the dust inside into the dust receiving portion 40 toward the dust suction portion 48. The bottom surface 34j and dust of the second part (scraping part) 38 so that the second part (scraping part) 38 can efficiently collect the dust on the inner bottom surface 40c to the dust suction part 48 side to the dust receiving part 40. The inner bottom surface 40c of the receiving portion 40 has a dust moving direction regulation configuration.
　図１５Ａ～図１５Ｄは、塵埃除去部３４の第２部品（掻き集め部品）３８が塵埃受け部４０の内底面４０ｃに沿って移動する様子を模式的に示す断面図である。図１５Ａ～図１５Ｄに示すように、第２部品（掻き集め部品）３８において、塵埃受け部４０の内底面４０ｃに対向する底面３４ｊは、曲面により構成されている。実施形態１においては、第２部品３８の前方側に形成された押圧面３４ｈの反対側の後方側が、底面３４ｊに連続する湾曲面で構成されている。実施形態１における第２部品３８の底面３４ｊは、吸引開口４０ｂ側（図１５Ａ～図１５Ｄの左側）が内底面４０ｃに最も近く、吸引開口４０ｂから離れるに従って内底面４０ｃから遠ざかるように湾曲する構成である。実施形態１における塵埃除去部３４の第２部品３８の底面３４ｊの形状は、摺動動作の方向に切断した断面において、前方側（押圧面３４ｈ）が略鉛直であり、後方側（底面３４ｊ）が湾曲しており、前方側の押圧面３４ｈの最下端が塵埃受け部４０の内底面４０ｃに最も近く、内底面４０ｃに近接している。 15A to 15D are cross-sectional views schematically showing how the second part (scraping part) 38 of the dust removing part 34 moves along the inner bottom surface 40c of the dust receiving part 40. As shown in FIGS. 15A to 15D, in the second component (scraping component) 38, the bottom surface 34j facing the inner bottom surface 40c of the dust receiving portion 40 is formed of a curved surface. In the first embodiment, the rear side opposite to the pressing surface 34h formed on the front side of the second component 38 is composed of a curved surface continuous with the bottom surface 34j. The bottom surface 34j of the second component 38 in the first embodiment has a structure in which the suction opening 40b side (left side of FIGS. 15A to 15D) is closest to the inner bottom surface 40c and is curved so as to move away from the inner bottom surface 40c as the distance from the suction opening 40b increases. Is. The shape of the bottom surface 34j of the second component 38 of the dust removing portion 34 in the first embodiment is such that the front side (pressing surface 34h) is substantially vertical in the cross section cut in the direction of the sliding operation, and the rear side (bottom surface 34j). Is curved, and the lowermost end of the pressing surface 34h on the front side is closest to the inner bottom surface 40c of the dust receiving portion 40 and close to the inner bottom surface 40c.
　なお、実施形態１の構成においては、第２部品３８の底面３４ｊを湾曲面で構成した例で説明するが、底面３４ｊの形状としては吸引開口４０ｂ側が内底面４０ｃに最も近い斜面で構成してもよい。 In the configuration of the first embodiment, an example in which the bottom surface 34j of the second component 38 is formed of a curved surface will be described, but the shape of the bottom surface 34j is such that the suction opening 40b side is formed of a slope closest to the inner bottom surface 40c. May be good.
　一方、第２部品３８の底面３４ｊが近接する塵埃受け部４０の内底面４０ｃは、塵埃の塊の移動方向を一方向に特定する移動方向規制形状を有している。実施形態１においては、図１５Ａ～図１５Ｄに示すように、塵埃除去部３４の移動方向である摺動動作の方向で切断した断面形状が、鋸刃の形状を有している。即ち、鋸刃の山形状において、吸引開口４０ｂ側（前方側）が略鉛直に近く切り立った形状であり、反対側（後方側）が鉛直線に対して角度を有してなだらかな面となる形状である。この結果、塵埃受け部４０の内部において、吸引開口４０ｂが形成されている方向（図１５Ａ～図１５Ｄにおいては左方向）には塵埃の塊がスムーズに移動可能であり、反対方向（図１５Ａ～図１５Ｄにおいては右方向）である吸引開口４０ｂから離れる方向には塵埃の塊が抵抗を受けて移動し難い構成となっている。 On the other hand, the inner bottom surface 40c of the dust receiving portion 40 adjacent to the bottom surface 34j of the second component 38 has a movement direction regulation shape that specifies the movement direction of the dust mass in one direction. In the first embodiment, as shown in FIGS. 15A to 15D, the cross-sectional shape cut in the direction of the sliding operation, which is the moving direction of the dust removing portion 34, has the shape of a saw blade. That is, in the mountain shape of the saw blade, the suction opening 40b side (front side) has a sharp shape that is close to vertical, and the opposite side (rear side) has an angle with respect to the vertical straight line and becomes a gentle surface. The shape. As a result, the dust mass can move smoothly in the direction in which the suction opening 40b is formed (leftward in FIGS. 15A to 15D) inside the dust receiving portion 40, and in the opposite direction (FIGS. 15A to 15A to 15D). In the direction away from the suction opening 40b, which is the right direction in FIG. 15D), the dust mass receives resistance and is difficult to move.
　上記のように構成された塵埃除去部３４及び塵埃受け部４０において、塵埃受け部４０の内部を塵埃除去部３４が吸引開口４０ｂから離れる方向（右方向）に移動（摺動）したとき（図１５Ａ～図１５Ｃ参照）、塵埃受け部４０の内底面４０ｃ上の塵埃の塊が第２部品３８の底面３４ｊにより押されたとしても、塵埃の塊は内底面４０ｃの塵埃移動方向規制形状により右方向への移動が妨げられている。この結果、図１５Ａ～図１５Ｃに示すように、塵埃受け部４０の内部においては、塵埃除去部３４の第２部品３８の底面３４ｊが塵埃の塊を乗り越えて右方向へ移動する。その結果、塵埃除去部３４が右方向への移動を行っても、塵埃受け部４０の内底面４０ｃ上の塵埃の塊は実質的に同じ位置にそのまま動くことなく存在することになる。それにより、前記の塵埃の塊が、吸引開口４０ｂと塵埃除去部３４の間に位置する。 In the dust removing portion 34 and the dust receiving portion 40 configured as described above, when the dust removing portion 34 moves (slides) in the direction away from the suction opening 40b (to the right) inside the dust receiving portion 40 (FIG. 15A to 15C), even if the dust mass on the inner bottom surface 40c of the dust receiving portion 40 is pushed by the bottom surface 34j of the second component 38, the dust mass is on the right due to the dust movement direction regulation shape of the inner bottom surface 40c. Movement in the direction is hindered. As a result, as shown in FIGS. 15A to 15C, inside the dust receiving portion 40, the bottom surface 34j of the second component 38 of the dust removing portion 34 gets over the dust mass and moves to the right. As a result, even if the dust removing portion 34 moves to the right, the dust mass on the inner bottom surface 40c of the dust receiving portion 40 does not move as it is at substantially the same position. As a result, the dust mass is located between the suction opening 40b and the dust removing portion 34.
　図１５Ａ～図１５Ｄに示されるように、塵埃受け部４０の内部を塵埃除去部３４が吸引開口４０ｂから離れる方向（右方向）に移動（摺動）するときに塵埃の塊を乗り越え、再度塵埃除去部３４が吸引開口４０ｂに近づく方向（左方向）に移動（摺動）するときに、塵埃除去部３４の第２部品３８が塵埃受け部４０の内底面４０ｃ上の前記塵埃の塊を押圧し、移動させる。図１５Ｄは、塵埃除去部３４の第２部品３８が塵埃受け部４０の内底面４０ｃに沿って移動し、塵埃受け部４０の内底面４０ｃ上の前記塵埃の塊を押圧面３４ｈにより押圧している状態を模式的に示した図である。図１５Ｄにおいて、押圧面３４ｈが塵埃の塊を押圧している方向（左方向）は吸引開口４０ｂが形成されている方向である。塵埃除去部３４が塵埃受け部４０の左端側に移動して、塵埃受け部４０の内底面４０ｃ上の塵埃の塊が左端側に集められると、吸引装置４２が起動して、塵埃受け部４０の左端にある吸引穴４０ｂから吸い込まれて屋外に排出される。 As shown in FIGS. 15A to 15D, when the dust removing portion 34 moves (slides) inside the dust receiving portion 40 in the direction away from the suction opening 40b (to the right), it gets over the dust mass and again dusts. When the removing portion 34 moves (slides) in the direction (leftward) approaching the suction opening 40b, the second component 38 of the dust removing portion 34 presses the dust mass on the inner bottom surface 40c of the dust receiving portion 40. And move it. In FIG. 15D, the second component 38 of the dust removing portion 34 moves along the inner bottom surface 40c of the dust receiving portion 40, and presses the dust mass on the inner bottom surface 40c of the dust receiving portion 40 by the pressing surface 34h. It is the figure which showed the state typically. In FIG. 15D, the direction in which the pressing surface 34h presses the dust mass (leftward direction) is the direction in which the suction opening 40b is formed. When the dust removing unit 34 moves to the left end side of the dust receiving unit 40 and the dust mass on the inner bottom surface 40c of the dust receiving unit 40 is collected on the left end side, the suction device 42 is activated and the dust receiving unit 40 is activated. It is sucked in from the suction hole 40b at the left end of the and discharged to the outside.
　なお、実施形態１における塵埃自動排出構成では、エアフィルタ１８に対するフィルタ清掃動作が開始すると、塵埃除去部３４が初期位置から右方向へ移動（摺動）して、ブラシ３０の先端部が第１の位置において、エアフィルタ１８に付着された塵埃をブラシ３０により掻き落とす動作を行う。その後、ブラシ３０の先端部が第２の位置に回動して、ブラシ３０に付着した塵埃を除去する塵埃除去動作を開始する構成である。本発明は、この実施形態１に開示された構成に限定されるものではなく、例えば、エアフィルタ１８に付着された塵埃をブラシ３０により掻き落とし動作を行った後に、ブラシ３０の先端部を第１の位置のままで塵埃除去部３４を右方向へ移動させて、ブラシ３０に対する塵埃除去動作を開始する構成としてもよい。また、エアフィルタ１８に付着された塵埃をブラシ３０により掻き落とし動作を行った後、ブラシ３０の先端部を第２の位置に回動させて、塵埃除去部３４を右方向へ移動させ、ブラシ３０に対する塵埃除去動作を行う構成としてもよい。 In the dust automatic discharge configuration according to the first embodiment, when the filter cleaning operation for the air filter 18 is started, the dust removing portion 34 moves (slides) from the initial position to the right, and the tip portion of the brush 30 is first. At the position of, the operation of scraping off the dust adhering to the air filter 18 with the brush 30 is performed. After that, the tip portion of the brush 30 rotates to the second position to start the dust removing operation of removing the dust adhering to the brush 30. The present invention is not limited to the configuration disclosed in the first embodiment. For example, after the dust adhering to the air filter 18 is scraped off by the brush 30, the tip of the brush 30 is removed. The dust removing unit 34 may be moved to the right while maintaining the position of 1 to start the dust removing operation on the brush 30. Further, after the dust adhering to the air filter 18 is scraped off by the brush 30, the tip portion of the brush 30 is rotated to the second position, and the dust removing portion 34 is moved to the right to move the brush. It may be configured to perform the dust removing operation with respect to 30.
　なお、実施形態１の構成においては、塵埃受け部４０の内底面４０ｃを、その断面が鋸刃状に形成される構成で説明したが、本発明はこれに限定されるものではない。図１６及び図１７は、塵埃受け部４０の内底面４０ｃ、及び塵埃除去部３４の底面３４ｊの変形例を模式的に示す断面図である。例えば、図１６の変形例に示すように、塵埃受け部４０の内底面４０ｃは、吸引開口４０ｂが形成された方向（図１６における左方向）に傾斜する、所謂、吸引開口４０ｂ側の方向が順目となる多数の毛４０ｄが植毛された構成でもよい。即ち、塵埃受け部４０の内底面４０ｃは、いわゆるエチケットブラシ（登録商標）のような構造を有してもよい。 In the configuration of the first embodiment, the inner bottom surface 40c of the dust receiving portion 40 has been described as having a saw-toothed cross section, but the present invention is not limited thereto. 16 and 17 are cross-sectional views schematically showing a modified example of the inner bottom surface 40c of the dust receiving portion 40 and the bottom surface 34j of the dust removing portion 34. For example, as shown in the modified example of FIG. 16, the inner bottom surface 40c of the dust receiving portion 40 is inclined in the direction in which the suction opening 40b is formed (leftward in FIG. 16), that is, the direction on the so-called suction opening 40b side is A large number of hairs 40d, which are in order, may be transplanted. That is, the inner bottom surface 40c of the dust receiving portion 40 may have a structure like a so-called etiquette brush (registered trademark).
　また、例えば、図１７の変形例に示すように、塵埃受け部４０の内底面４０ｃに多数の毛４０ｄが植毛された構成と共に、塵埃除去部３４の第２部品３８の底面３４ｊには、塵埃受け部４０の多数の毛４０ｄに接触する多数の毛３４ｋを有する構成としてもよい。この構成によって、塵埃受け部４０の内底面４０ｃにおいては、実施の形態１の構成と同様に、塵埃に対する抵抗力の違いを実現することができる。 Further, for example, as shown in the modified example of FIG. 17, a large number of hairs 40d are planted on the inner bottom surface 40c of the dust receiving portion 40, and dust is formed on the bottom surface 34j of the second component 38 of the dust removing portion 34. It may be configured to have a large number of hairs 34k in contact with a large number of hairs 40d of the receiving portion 40. With this configuration, the inner bottom surface 40c of the dust receiving portion 40 can realize a difference in resistance to dust, as in the configuration of the first embodiment.
　［塵埃手動排出構成］
　次に、実施形態１の空気調和機において、フィルタ清掃装置３により塵埃受け部４０に掻き落とされた塵埃を使用者が手動で廃棄する塵埃手動排出構成について説明する。実施形態１の空気調和機においては、当該空気調和機の設置環境が塵埃受け部４０に掻き落とされた塵埃を吸引装置４２による吸引動作により吸引管４４を介して屋外へ排出する塵埃自動排出を行えない状況の場合には、塵埃手動排出構成に変更して対応することが可能である。 [Dust manual discharge configuration]
Next, in the air conditioner of the first embodiment, a dust manual discharge configuration in which the user manually disposes of the dust scraped off by the filter cleaning device 3 on the dust receiving portion 40 will be described. In the air conditioner of the first embodiment, the installation environment of the air conditioner automatically discharges the dust scraped off by the dust receiving portion 40 to the outside through the suction pipe 44 by the suction operation by the suction device 42. If this is not possible, it is possible to change to a dust manual discharge configuration.
　実施形態１の空気調和機における塵埃手動排出構成は、掻き落とされた塵埃を保持する塵埃受け部４０を使用者が本体２から取り外して、塵埃受け部４０の内部の塵埃を廃棄する構成である。従って、空気調和機の設置時においてその設置環境に応じて塵埃自動排出構成とするか、塵埃手動排出構成とするかが決定される。 The dust manual discharge configuration in the air conditioner of the first embodiment is a configuration in which the user removes the dust receiving portion 40 for holding the scraped dust from the main body 2 and discards the dust inside the dust receiving portion 40. .. Therefore, when installing the air conditioner, it is determined whether to use the automatic dust discharge configuration or the manual dust discharge configuration according to the installation environment.
　塵埃手動排出構成は、前述の塵埃自動排出構成と同様に、エアフィルタ１８が往復移動してエアフィルタ１８に付着した塵埃をブラシ３０により掻き落とすよう構成されている（図３及び図４参照）。また、塵埃除去部３４と接触可能な位置にあるブラシ３０を揺動させて、ブラシ３０に付着した塵埃を塵埃除去部３４により塵埃受け部４０に掻き落とす構成（図５Ａ～図５Ｃ参照）についても、前述の塵埃自動排出構成と同様である。即ち、塵埃手動排出構成においても、エアフィルタ１８に対するブラシ３０による掻き落とし動作を行った後、ブラシ３０による「揺動掻き落とし動作」、及び塵埃除去部３４の移動（摺動）による「摺動掻き落とし動作」を行っている。但し、塵埃自動排出構成においては、塵埃除去部３４による「摺動掻き集め動作」を行わない構成である。 Similar to the above-mentioned automatic dust discharge configuration, the dust manual discharge configuration is configured such that the air filter 18 reciprocates and scrapes off the dust adhering to the air filter 18 with the brush 30 (see FIGS. 3 and 4). .. Further, the brush 30 at a position where it can come into contact with the dust removing portion 34 is swung, and the dust adhering to the brush 30 is scraped off by the dust removing portion 34 to the dust receiving portion 40 (see FIGS. 5A to 5C). Is the same as the above-mentioned automatic dust discharge configuration. That is, even in the dust manual discharge configuration, after the air filter 18 is scraped off by the brush 30, the "swing scraping operation" by the brush 30 and the "sliding" by the movement (sliding) of the dust removing portion 34 are performed. "Scraping operation" is performed. However, in the dust automatic discharge configuration, the dust removing unit 34 does not perform the "sliding scraping operation".
　実施形態１の空気調和機の塵埃手動排出構成においては、使用者が本体２から塵埃受け部４０を容易に取り外して、塵埃受け部４０の内部の塵埃を廃棄できる構成である。図１８は、実施形態１の空気調和機において、室内機１の前面パネル４が開放された状態を示す断面図である。図１８に示す状態においては、アクティブクリーンフィルタ１１がエアフィルタ１８の上面側に移動するよう構成されている。この状態は、前面開口部２ａが開放されて、塵埃除去部３４を下方から包むように設けられた塵埃受け部４０が表出した状態である。 In the dust manual discharge configuration of the air conditioner of the first embodiment, the user can easily remove the dust receiving portion 40 from the main body 2 and dispose of the dust inside the dust receiving portion 40. FIG. 18 is a cross-sectional view showing a state in which the front panel 4 of the indoor unit 1 is opened in the air conditioner of the first embodiment. In the state shown in FIG. 18, the active clean filter 11 is configured to move to the upper surface side of the air filter 18. In this state, the front opening 2a is opened, and the dust receiving portion 40 provided so as to wrap the dust removing portion 34 from below is exposed.
　図１９及び図２０は、実施形態１における室内機１の本体２の内部のフィルタ清掃装置３を示す斜視図である。図１９は、塵埃受け部４０における左端側に設けられた蓋４７が開けられて、塵埃除去部３４の第２部品（掻き集め部品）３８が第１部品（掻き落とし部品）３６から取り外される状態を示している。図２０は、図１９に示した塵埃除去部３４の第２部品（掻き集め部品）３８が取り外された状態において、塵埃受け部４０が室内機１の本体２から取り外されることを示している。 19 and 20 are perspective views showing the filter cleaning device 3 inside the main body 2 of the indoor unit 1 according to the first embodiment. FIG. 19 shows a state in which the lid 47 provided on the left end side of the dust receiving portion 40 is opened, and the second component (scraping component) 38 of the dust removing portion 34 is removed from the first component (scraping component) 36. It shows. FIG. 20 shows that the dust receiving unit 40 is removed from the main body 2 of the indoor unit 1 in a state where the second component (scraping component) 38 of the dust removing unit 34 shown in FIG. 19 is removed.
　前述の図８及び図９に示したように、塵埃除去部３４は、第１部品（掻き落とし部品）３６と第２部品（掻き集め部品）３８とを有し、第２部品３８が第１部品３６から取り外し可能な脱着構成である。塵埃受け部４０には、塵埃除去部３４の第１部品３６から第２部品３８を取り外すための開口部４０ａ（図１９参照）が形成されている。開口部４０ａには取り外し可能な蓋４７が装着されており、通常、開口部４０ａは閉鎖されている。開口部４０ａが形成されている位置は、前述の図６Ａに示した塵埃除去部３４の初期位置の近傍であり、開口部４０ａを通して塵埃除去部３４の第２部品３８を取り出せる位置である。 As shown in FIGS. 8 and 9 described above, the dust removing unit 34 has a first component (scraping component) 36 and a second component (scraping component) 38, and the second component 38 is the first component. It is a removable configuration that can be removed from 36. The dust receiving portion 40 is formed with an opening 40a (see FIG. 19) for removing the second component 38 from the first component 36 of the dust removing portion 34. A removable lid 47 is attached to the opening 40a, and the opening 40a is usually closed. The position where the opening 40a is formed is near the initial position of the dust removing portion 34 shown in FIG. 6A, and is a position where the second component 38 of the dust removing portion 34 can be taken out through the opening 40a.
　実施形態１の空気調和機を塵埃手動排出構成とする場合には、前面パネル４を開いて前面開口部２ａを開放状態とし、塵埃受け部４０の開口部４０ａに装着されている蓋４７を外し、塵埃除去部３４の第２部品３８が開口部４０ａを通して第１部品３６から取り外される。このように、塵埃除去部３４の第２部品３８を第１部品３６から取り外すことにより、塵埃除去部３４を下方から包むように設けられた塵埃受け部４０を容易に取り外すことが可能となる。 When the air conditioner of the first embodiment has a dust manual discharge configuration, the front panel 4 is opened to open the front opening 2a, and the lid 47 attached to the opening 40a of the dust receiving portion 40 is removed. The second component 38 of the dust removing portion 34 is removed from the first component 36 through the opening 40a. By removing the second part 38 of the dust removing part 34 from the first part 36 in this way, the dust receiving part 40 provided so as to wrap the dust removing part 34 from below can be easily removed.
　図２１は、塵埃受け部４０の内部に第１部品３６と第２部品３８とで構成された塵埃除去部３４が配設された状態を示す図であり、ブラシ３０の延在方向に直交する方向に切断した断面図である。図２１に示した状態においては、塵埃除去部３４が第２部品３８を有するため塵埃受け部４０を取り外せない状態となっている。即ち、本体２に装着された塵埃受け部４０における背面側の壁面の少なくとも一部は、塵埃除去部３４の第１部品３６の下方に装着された第２部品３８の最下端の位置より高くなるように配設されており、塵埃受け部４０の背面側の壁面の少なくとも一部が装着された第２部品３８に接触して、塵埃受け部４０の取り外しができない構成となっている。また、本体２に装着された塵埃受け部４０における背面側の壁面の少なくとも一部は、塵埃除去部３４の第１部品３６の最下端の位置より低い位置となるように配設されており、第２部品３８が取り外された状態では、塵埃受け部４０を本体２から容易に手前側に引き出して取り外すことができる構成となっている。塵埃除去部３４の第１部品３６の下方に装着された第２部品３８の最下端の位置より高くなるように配設され、塵埃除去部３４の第１部品３６の最下端の位置より低い位置となるように配設された塵埃受け部４０における背面側の壁面部分は前記塵埃除去部の停止する初期位置近傍に形成された構成となっている。図２１に示す状態が実施形態１の空気調和機における塵埃自動排出構成であり、塵埃受け部４０の内部の塵埃が吸引装置４２による吸引動作により屋外へ排出される構成となる。 FIG. 21 is a view showing a state in which the dust removing portion 34 composed of the first component 36 and the second component 38 is arranged inside the dust receiving portion 40, and is orthogonal to the extending direction of the brush 30. It is sectional drawing cut in the direction. In the state shown in FIG. 21, since the dust removing portion 34 has the second component 38, the dust receiving portion 40 cannot be removed. That is, at least a part of the wall surface on the back side of the dust receiving portion 40 mounted on the main body 2 is higher than the position of the lowermost end of the second component 38 mounted below the first component 36 of the dust removing portion 34. The dust receiving portion 40 is arranged so as to be arranged so that at least a part of the wall surface on the back side of the dust receiving portion 40 comes into contact with the mounted second component 38, and the dust receiving portion 40 cannot be removed. Further, at least a part of the wall surface on the back side of the dust receiving portion 40 mounted on the main body 2 is arranged so as to be lower than the lowermost position of the first component 36 of the dust removing portion 34. When the second component 38 is removed, the dust receiving portion 40 can be easily pulled out from the main body 2 toward the front side and removed. It is arranged so as to be higher than the position of the lowermost end of the second part 38 mounted below the first part 36 of the dust removing part 34, and is lower than the position of the lowermost end of the first part 36 of the dust removing part 34. The wall surface portion on the back surface side of the dust receiving portion 40 arranged so as to be is formed in the vicinity of the initial position where the dust removing portion stops. The state shown in FIG. 21 is the dust automatic discharge configuration in the air conditioner of the first embodiment, and the dust inside the dust receiving portion 40 is discharged to the outside by the suction operation by the suction device 42.
　図２２は、ブラシ３０の延在方向に直交する方向に切断した断面図であり、塵埃除去部３４の第２部品３８が取り外された構成において、塵埃受け部４０を本体２から取り外している状態を示す。ブラシ３０の延在方向に直交する方向に切断した断面図である。図２２に示す状態が実施形態１の空気調和機における塵埃手動排出構成であり、塵埃受け部４０を本体２から容易に取り外すことができる状態となっている。図２２に示すように、塵埃受け部４０は本体２から前面側（手前側）に引き出して、本体２から取り外すように構成されている。 FIG. 22 is a cross-sectional view cut in a direction orthogonal to the extending direction of the brush 30, and is a state in which the dust receiving portion 40 is removed from the main body 2 in the configuration in which the second component 38 of the dust removing portion 34 is removed. Is shown. It is sectional drawing which cut in the direction orthogonal to the extending direction of a brush 30. The state shown in FIG. 22 is the dust manual discharge configuration in the air conditioner of the first embodiment, and the dust receiving portion 40 can be easily removed from the main body 2. As shown in FIG. 22, the dust receiving portion 40 is configured to be pulled out from the main body 2 to the front side (front side) and removed from the main body 2.
　図２３は、塵埃受け部４０の左端側の近傍を下方から見た斜視図であり、塵埃受け部４０の底面における左端の吸引開口４０ｂを示している。図２３に示すように、吸引開口４０ｂは、塵埃受け部４０の底面に設けられたスライド式の扉４９により開閉可能に構成されている。即ち、塵埃自動排出構成においては、塵埃受け部４０は、扉４９が開放状態であり、塵埃受け部４０の底面左端に吸引開口４０ｂが形成された状態となる。従って、塵埃自動排出構成においては、塵埃受け部４０の底面左端側に設けられた塵埃吸引部４８が、吸引開口４０ｂを通して塵埃受け部４０からの塵埃を受け取る構成となる（図６Ｄ参照）。 FIG. 23 is a perspective view of the vicinity of the left end side of the dust receiving portion 40 as viewed from below, and shows the suction opening 40b at the left end on the bottom surface of the dust receiving portion 40. As shown in FIG. 23, the suction opening 40b is configured to be openable and closable by a sliding door 49 provided on the bottom surface of the dust receiving portion 40. That is, in the dust receiving portion 40, the door 49 of the dust receiving portion 40 is in an open state, and a suction opening 40b is formed at the left end of the bottom surface of the dust receiving portion 40. Therefore, in the dust automatic discharge configuration, the dust suction unit 48 provided on the left end side of the bottom surface of the dust receiving unit 40 receives dust from the dust receiving unit 40 through the suction opening 40b (see FIG. 6D).
　一方、塵埃手動排出構成においては、吸引開口４０ｂに対して扉４９が閉じた状態であり、塵埃受け部４０の底面左端の吸引開口４０ｂが閉鎖されている。図２４は、塵埃受け部４０の左端側の近傍を下方から見た斜視図であり、塵埃受け部４０の底面左端の吸引開口４０ｂが扉４９により閉鎖されている状態を示している。塵埃手動排出構成においては、図２４に示す状態の塵埃受け部４０が本体２の前面開口部２ａにおける所定位置に装着される。塵埃受け部４０が装着される位置は、図１８に示すように、ブラシ３０の延在方向に沿ってブラシ３０の下方に配置され、塵埃除去部３４の第１部品（掻き落とし部品）３６を下方から覆うように装着される。 On the other hand, in the dust manual discharge configuration, the door 49 is closed with respect to the suction opening 40b, and the suction opening 40b at the left end of the bottom surface of the dust receiving portion 40 is closed. FIG. 24 is a perspective view of the vicinity of the left end side of the dust receiving portion 40 as viewed from below, and shows a state in which the suction opening 40b at the left end of the bottom surface of the dust receiving portion 40 is closed by the door 49. In the dust manual discharge configuration, the dust receiving portion 40 in the state shown in FIG. 24 is mounted at a predetermined position in the front opening 2a of the main body 2. As shown in FIG. 18, the position where the dust receiving portion 40 is mounted is arranged below the brush 30 along the extending direction of the brush 30, and the first component (scraping component) 36 of the dust removing portion 34 is attached. It is installed so as to cover it from below.
　図２５Ａ～図２５Ｄは、塵埃手動排出構成において、ブラシ３０に付着した塵埃を塵埃除去部３４が掻き落とすときの塵埃除去動作（「揺動掻き落とし動作」及び「摺動掻き落とし動作」）を示す図である。実施形態１における塵埃手動排出構成では、塵埃除去部３４が第２部品３８を有していないため、「摺動掻き集め動作」が行われず、第１部品３６による「摺動掻き落とし動作」が行われる構成となっている。 25A to 25D show dust removing operations (“swing scraping operation” and “sliding scraping operation”) when the dust removing unit 34 scrapes off the dust adhering to the brush 30 in the dust manual discharge configuration. It is a figure which shows. In the dust manual discharge configuration according to the first embodiment, since the dust removing unit 34 does not have the second component 38, the "sliding scraping operation" is not performed, and the "sliding scraping operation" by the first component 36 is performed. It has a structure that is
　図２５Ａは、塵埃受け部４０の内部における塵埃除去部３４の初期位置を示している。即ち、図２５Ａは、塵埃除去動作の開始前及び終了後における塵埃除去部３４の停止位置を示している。この初期位置においては、塵埃除去部３４が幅方向に延在するブラシ３０の左端に配置されている。実施形態１において、塵埃除去部３４の初期位置としては、ブラシ３０の左端の位置として説明するが、この構成に本発明を限定するものではなく、空気調和機における内部構成や、エアフィルタ１８に対するブラシ３０と塵埃除去部３４とによる塵埃除去の効率等が考慮されて適宜決定される。 FIG. 25A shows the initial position of the dust removing portion 34 inside the dust receiving portion 40. That is, FIG. 25A shows the stop positions of the dust removing unit 34 before and after the start and end of the dust removing operation. In this initial position, the dust removing portion 34 is arranged at the left end of the brush 30 extending in the width direction. In the first embodiment, the initial position of the dust removing unit 34 will be described as the position of the left end of the brush 30, but the present invention is not limited to this configuration, and the internal configuration of the air conditioner and the air filter 18 are not limited to this configuration. It is appropriately determined in consideration of the efficiency of dust removal by the brush 30 and the dust removing unit 34.
　図２５Ｂは、塵埃除去部３４が初期位置とは反対の位置（退避位置）に配置された状態であり、ブラシ３０の右端に配置された状態を示している。図２５Ｂに示す状態において、エアフィルタ１８が往復動作を行いブラシ３０によりエアフィルタ１８に対する掻き落とし動作が行われる。従って、塵埃除去部３４のブラシ３０における右端の位置が、退避位置となる。また、実施形態１においては、塵埃除去部３４がブラシ３０の右端位置にあるとき、塵埃除去部３４による塵埃除去動作における実質的な開始位置となる。 FIG. 25B shows a state in which the dust removing portion 34 is arranged at a position (retracted position) opposite to the initial position, and is arranged at the right end of the brush 30. In the state shown in FIG. 25B, the air filter 18 reciprocates, and the brush 30 scrapes the air filter 18. Therefore, the position at the right end of the brush 30 of the dust removing unit 34 is the retracted position. Further, in the first embodiment, when the dust removing unit 34 is located at the right end position of the brush 30, it is a substantially starting position in the dust removing operation by the dust removing unit 34.
　図２５Ｃは、塵埃除去部３４が塵埃受け部４０の内部を摺動して、ブラシ３０に付着した塵埃を塵埃受け部４０に掻き落とす「揺動掻き落とし動作」及び「摺動掻き落とし動作」を行っているときの状態を示している。また、図２５Ｄは、塵埃除去部３４がブラシ３０における左端に到達し、塵埃受け部４０の内部に塵埃が掻き落とされた状態を示している。この状態において、塵埃受け部４０が本体２から取り外されて、塵埃受け部４０の内部の塵埃が廃棄される。 FIG. 25C shows a “swing scraping operation” and a “sliding scraping operation” in which the dust removing portion 34 slides inside the dust receiving portion 40 to scrape the dust adhering to the brush 30 onto the dust receiving portion 40. It shows the state when doing. Further, FIG. 25D shows a state in which the dust removing portion 34 reaches the left end of the brush 30 and the dust is scraped off inside the dust receiving portion 40. In this state, the dust receiving portion 40 is removed from the main body 2, and the dust inside the dust receiving portion 40 is discarded.
　前述のように、ブラシ３０が「揺動掻き落とし動作」（図５Ａ～図５Ｃ参照）を行いつつ、塵埃除去部３４の第１部品（掻き落とし部品）３６は、図２５Ｃに示すように、ブラシ３０の先端部を擦るようにブラシ３０の延在方向（すなわち、室内機１の幅方向）に移動（摺動）することにより、ブラシ３０に付着した塵埃が塵埃除去部３４の第１部品（掻き落とし部品）３６により確実に掻き落とされる。 As described above, while the brush 30 performs the "swinging scraping operation" (see FIGS. 5A to 5C), the first component (scraping component) 36 of the dust removing unit 34 is as shown in FIG. 25C. By moving (sliding) in the extending direction (that is, the width direction of the indoor unit 1) of the brush 30 so as to rub the tip of the brush 30, the dust adhering to the brush 30 is the first component of the dust removing unit 34. (Scraped parts) It is surely scraped off by 36.
　上記のように、実施形態１に係る空気調和機においては、空気調和機の設置環境に応じて、フィルタ清掃装置３により集められた塵埃を自動で屋外へ排出する塵埃自動排出構成と、手動で廃棄する塵埃手動排出構成とを有する構成である。これにより、実施形態１に係る空気調和機の構成は、室内空間の塵埃を屋外へ排出するための配管等を設けることが困難な設置環境の場合であっても、フィルタ清掃装置３により集められた塵埃を使用者が容易に廃棄することが可能な構成となる。このように、本発明の空気調和機の構成によれば、空気調和機の設置条件が緩和されており、汎用性の高い機器となる。 As described above, in the air conditioner according to the first embodiment, there is an automatic dust discharge configuration for automatically discharging the dust collected by the filter cleaning device 3 to the outside according to the installation environment of the air conditioner, and a manual dust discharge configuration. It is a configuration having a dust manual discharge configuration for disposal. As a result, the configuration of the air conditioner according to the first embodiment is collected by the filter cleaning device 3 even in an installation environment where it is difficult to provide a pipe or the like for discharging dust in the indoor space to the outside. The configuration is such that the user can easily dispose of the dust. As described above, according to the configuration of the air conditioner of the present invention, the installation conditions of the air conditioner are relaxed, and the device becomes highly versatile.
　上記のように、実施形態１において具体的な構成で説明した本発明の空気調和機においては、塵埃自動排出構成と塵埃手動排出構成とを切り替えることが可能な構成であるため、以下の説明する変形例と共に優れた効果を奏するものである。 As described above, the air conditioner of the present invention described in the specific configuration in the first embodiment has a configuration in which the automatic dust discharge configuration and the manual dust discharge configuration can be switched, and thus will be described below. It produces an excellent effect along with a modified example.
　本発明の空気調和機における塵埃自動排出構成と塵埃手動排出構成では、エアフィルタの表面に付着した塵埃をブラシにより効率高く塵埃受け部の内部に掻き落とすと共に、ブラシに付着した塵埃をブラシと塵埃除去部との相対移動により効率高く塵埃受け部の内部に掻き落として、塵埃受け部の内部の塵埃を廃棄することが可能となる。本発明においては、塵埃除去部がブラシに接触してブラシの延在方向に相対移動することによって、ブラシに付着した塵埃同士が絡み合って纏まり易くなり、従来よりも塵埃の除去効率を向上させることができる。また、ブラシと塵埃除去部との接触部分を小さくして塵埃除去部がブラシから受ける摩擦力を小さくすることができるので、塵埃除去部を移動させる駆動力を小さくすることができる。さらに、塵埃除去部自体の大きさも小さくすることができる。 In the automatic dust discharge configuration and the manual dust discharge configuration of the air conditioner of the present invention, the dust adhering to the surface of the air filter is efficiently scraped off to the inside of the dust receiving portion by the brush, and the dust adhering to the brush is scraped off by the brush and the dust. By moving relative to the removing portion, the dust inside the dust receiving portion can be efficiently scraped off, and the dust inside the dust receiving portion can be discarded. In the present invention, the dust removing portion comes into contact with the brush and moves relative to each other in the extending direction of the brush, so that the dust adhering to the brush is easily entangled with each other and gathered, and the dust removing efficiency is improved as compared with the conventional case. Can be done. Further, since the contact portion between the brush and the dust removing portion can be reduced to reduce the frictional force received by the dust removing portion from the brush, the driving force for moving the dust removing portion can be reduced. Further, the size of the dust removing portion itself can be reduced.
　本発明の空気調和機における塵埃自動排出構成によれば、エアフィルタ及びブラシから掻き落とされた塵埃が確実に一定箇所に掻き集められて屋外へ自動的に排出することが可能な構成となる。また、本発明の空気調和機における塵埃手動排出構成によれば、塵埃自動排出構成が適用できない設置環境においては、エアフィルタ及びブラシから塵埃受け部の内部に掻き落とされた塵埃を容易に廃棄することが可能な構成となる。 According to the dust automatic discharge configuration in the air conditioner of the present invention, the dust scraped off from the air filter and the brush can be reliably collected at a certain place and automatically discharged to the outside. Further, according to the dust manual discharge configuration in the air conditioner of the present invention, in an installation environment to which the dust automatic discharge configuration cannot be applied, the dust scraped from the air filter and the brush into the dust receiving portion is easily discarded. It becomes a possible configuration.
　本発明の空気調和機における塵埃自動排出構成では、塵埃受け部（４０）の内部の塵埃を吸引装置（４２）に繋がる塵埃吸引部（４８）に移動させてから吸引装置（４２）を起動する構成であるため、塵埃受け部（４０）における気密性を高くする必要がない。このため、塵埃受け部（４０）の構成として簡略化することが可能となり、吸引装置（４２）の駆動力を小さくすることができると共に、吸引装置（４２）の吸引時間を短くすることができる。その結果、本発明によれば、吸引装置（４２）の運転時の騒音を低減化することができる。 In the dust automatic discharge configuration in the air conditioner of the present invention, the dust inside the dust receiving unit (40) is moved to the dust suction unit (48) connected to the suction device (42), and then the suction device (42) is started. Since it is configured, it is not necessary to increase the airtightness in the dust receiving portion (40). Therefore, the configuration of the dust receiving portion (40) can be simplified, the driving force of the suction device (42) can be reduced, and the suction time of the suction device (42) can be shortened. .. As a result, according to the present invention, it is possible to reduce the noise during operation of the suction device (42).
　本発明の空気調和機においては、塵埃除去部（３４）が、ブラシ（３０）の延在方向に対して交差する方向に延在する第１ブレード部（前方ブレード３４ａ及び後方ブレード３４ｂ）を有しているので、塵埃の除去効率を一層向上させることができる。 In the air conditioner of the present invention, the dust removing portion (34) has a first blade portion (front blade 34a and rear blade 34b) extending in a direction intersecting the extending direction of the brush (30). Therefore, the efficiency of removing dust can be further improved.
　本発明の空気調和機において、ブラシ（３０）は、塵埃除去部（３４）がブラシ３０に接触可能な状態で、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。このため、本発明によれば、ブラシ（３０）に付着した塵埃の除去効率を一層向上させることができる。 In the air conditioner of the present invention, the brush (30) is configured to swing in a direction intersecting the extending direction of the brush (30) with the dust removing portion (34) in contact with the brush 30. ing. Therefore, according to the present invention, the efficiency of removing dust adhering to the brush (30) can be further improved.
　本発明の空気調和機において、塵埃除去部（３４）は、ブラシ（３０）の延在方向と実質的に平行に延設された第２ブレード部（側方ブレード３４ｅ、３４ｆ）がブラシ（３０）の揺動範囲内に配置されているため、ブラシ（３０）の揺動動作において第２ブレード部（側方ブレード３４ｅ、３４ｆ）がブラシ（３０）に付着した塵埃を掻き落とすように構成されている。このため、本発明によれば、塵埃の除去効率を一層向上させることができる。 In the air conditioner of the present invention, the dust removing portion (34) has a brush (30) having a second blade portion ( side blades 34e, 34f) extending substantially parallel to the extending direction of the brush (30). ) Is arranged within the swing range of the brush (30), so that the second blade portions ( side blades 34e and 34f) scrape off the dust adhering to the brush (30) in the swing operation of the brush (30). ing. Therefore, according to the present invention, the efficiency of removing dust can be further improved.
　本発明の空気調和機において、第１ブレード部（前方ブレード３４ａ及び後方ブレード３４ｂ）は、回転軸３２ａを中心とする円弧状に形成されている。これにより、第１ブレード部（前方ブレード３４ａ及び後方ブレード３４ｂ）は、ブラシ（３０）の各毛に対して、ブラシ（３０）の基端部から同じ距離の位置に接触して、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。その結果、本発明によれば、塵埃の除去効率を一層向上させることができる。 In the air conditioner of the present invention, the first blade portion (front blade 34a and rear blade 34b) is formed in an arc shape centered on the rotation shaft 32a. As a result, the first blade portion (front blade 34a and rear blade 34b) contacts each bristles of the brush (30) at the same distance from the base end portion of the brush (30), and the brush (30). ) Is configured to scrape off the dust adhering to it. As a result, according to the present invention, the dust removal efficiency can be further improved.
　本発明の空気調和機の塵埃自動排出構成においては、塵埃除去部（３４）が掻き落とし部品として上方に配設された第１部品（３６）と、掻き集め部品として下方に配設された第２部品（３８）との組立構造である。また、塵埃除去部（３４）が塵埃受け部（４０）により下方から包むように構成されている。このため、塵埃受け部（４０）の形状を大きく設計する場合であっても、塵埃除去部（３４）の下方にある第２部品（３８）の形状を大きく構成して対応することが可能となる。また、塵埃除去部（３４）の底面（３４ｊ）と塵埃受け部（４０）の内底面（４０ｃ）との隙間を所望の距離とするために、塵埃除去部（３４）の第２部品（３８）の形状及び／又は寸法の変更により対応することが可能な構成となる。その結果、本発明によれば、空気調和機における設計変更に対して容易に対応することが可能な構成であると共に、塵埃受け部（４０）の内部の塵埃を確実に吸引開口側に集めることが可能となり、塵埃の除去効率を一層向上させることができる。 In the dust automatic discharge configuration of the air conditioner of the present invention, the dust removing portion (34) is arranged above as a scraping component (36) and the second component (36) disposed below as a scraping component. It is an assembly structure with the part (38). Further, the dust removing portion (34) is configured to be wrapped by the dust receiving portion (40) from below. Therefore, even when the shape of the dust receiving portion (40) is designed to be large, the shape of the second component (38) below the dust removing portion (34) can be configured to be large. Become. Further, in order to make the gap between the bottom surface (34j) of the dust removing portion (34) and the inner bottom surface (40c) of the dust receiving portion (40) a desired distance, the second component (38) of the dust removing portion (34) ) Can be changed by changing the shape and / or dimensions. As a result, according to the present invention, the configuration is such that it is possible to easily respond to a design change in the air conditioner, and the dust inside the dust receiving portion (40) is surely collected on the suction opening side. This makes it possible to further improve the dust removal efficiency.
　また、本発明の空気調和機の塵埃自動排出構成において、塵埃除去部（３４）は、後方空間（Ｓ２）に落下した塵埃を誘導面（３４ｇ）によって塵埃除去部（３４）における押圧面（３４ｈ）より前方側（吸引開口側）へ誘導するように構成されている。その結果、本発明によれば、塵埃の除去効率を一層向上させることができる。 Further, in the dust automatic discharge configuration of the air conditioner of the present invention, the dust removing unit (34) uses the guiding surface (34 g) to push the dust that has fallen into the rear space (S2) on the dust removing unit (34). ) Is configured to guide to the front side (suction opening side). As a result, according to the present invention, the dust removal efficiency can be further improved.
　本発明の空気調和機の塵埃自動排出構成において、塵埃除去部（３４）は、誘導面（３４ｇ）の下方に、誘導面（３４ｇ）よりも鉛直方向に対する傾斜角度が小さい押圧面（３４ｈ）を有している。このため、押圧面（３４ｈ）より前方側（吸引開口側）にある塵埃を吸引穴側に確実により一層移動させやすい構成となっている。この結果、本発明によれば、塵埃の除去効率を一層向上させることができる。 In the dust automatic discharge configuration of the air conditioner of the present invention, the dust removing unit (34) has a pressing surface (34h) below the guiding surface (34g) having a smaller inclination angle with respect to the vertical direction than the guiding surface (34g). Have. Therefore, the dust on the front side (suction opening side) of the pressing surface (34h) is surely more easily moved to the suction hole side. As a result, according to the present invention, the dust removal efficiency can be further improved.
　本発明の空気調和機の塵埃自動排出構成においては、塵埃受け部（４０）の内底面（４０ｃ）は、この内底面上の塵埃に対して、吸引開口（４０ｂ）から離れる方向への移動より、吸引開口（４０ｂ）に近づく方向への移動を容易とする構成を有している。この構成によれば、ブラシ（３０）から塵埃受け部（４０）の内底面上に掻き落とされた塵埃を、塵埃除去部（３４）により吸引開口（４０ｂ）が設けられている方向に掻き集めることが容易な構成となる。その結果、本発明によれば、塵埃の除去効率を一層向上させることができる。 In the dust automatic discharge configuration of the air conditioner of the present invention, the inner bottom surface (40c) of the dust receiving portion (40) moves in the direction away from the suction opening (40b) with respect to the dust on the inner bottom surface. , It has a structure that facilitates movement in a direction approaching the suction opening (40b). According to this configuration, the dust scraped from the brush (30) onto the inner bottom surface of the dust receiving portion (40) is collected by the dust removing portion (34) in the direction in which the suction opening (40b) is provided. This is an easy configuration. As a result, according to the present invention, the dust removal efficiency can be further improved.
　本発明の空気調和機においては、例えば、塵埃受け部（４０）の内底面（４０ｃ）は、塵埃除去部（３４）の摺動動作の方向に直交する断面形状が鋸刃状に構成され、塵埃受け部（４０）の内底面上の塵埃の塊が一方の方向に移動するときは抵抗が大きく、他方の方向に移動するときは抵抗が小さくなる形状を有している。その結果、本発明によれば、より簡易な構成で、塵埃受け部（４０）の内底面上の塵埃の塊に対する抵抗力の違いにより、特定の方向へ塵埃を掻き集めることが容易な構成を実現することができる。 In the air conditioner of the present invention, for example, the inner bottom surface (40c) of the dust receiving portion (40) has a saw blade shape having a cross-sectional shape orthogonal to the sliding operation direction of the dust removing portion (34). When the dust mass on the inner bottom surface of the dust receiving portion (40) moves in one direction, the resistance is large, and when the dust mass moves in the other direction, the resistance is small. As a result, according to the present invention, there is a simpler configuration in which it is easy to collect dust in a specific direction due to the difference in resistance to a mass of dust on the inner bottom surface of the dust receiving portion (40). It can be realized.
　本発明の空気調和機の塵埃自動排出構成において、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、塵埃受け部（４０）の吸引開口側が内底面（４０ｃ）に最も近く、吸引開口（４０ｂ）から離れるに従って内底面（４０ｃ）から遠ざかるように湾曲又は斜面で構成されている。この構成によれば、塵埃受け部（４０）の内底面（４０ｃ）において、ブラシ（３０）から掻き落とされた塵埃が塵埃除去部（３４）よりも吸引開口側とは反対側に落下したとしても、当該塵埃を塵埃除去部（３４）により吸引開口（４０ｂ）の近傍に容易に移動させることができる。その結果、本発明によれば、塵埃の除去効率を一層向上させることができる。 In the dust automatic discharge configuration of the air conditioner of the present invention, the bottom surface (34j) of the dust removing portion (34) facing the inner bottom surface (40c) of the dust receiving portion (40) is a suction opening of the dust receiving portion (40). The side is closest to the inner bottom surface (40c) and is curved or sloped so as to move away from the inner bottom surface (40c) as it moves away from the suction opening (40b). According to this configuration, on the inner bottom surface (40c) of the dust receiving portion (40), the dust scraped off from the brush (30) is assumed to have fallen from the dust removing portion (34) to the side opposite to the suction opening side. Also, the dust can be easily moved to the vicinity of the suction opening (40b) by the dust removing portion (34). As a result, according to the present invention, the dust removal efficiency can be further improved.
　本発明の空気調和機の塵埃自動排出構成において、塵埃除去部（３４）には、塵埃除去部（３４）よりも吸引開口側の空間と塵埃除去部（３４）よりも吸引開口側とは反対の空間とを連通する吸気穴（３４ｉ）が形成されている。この構成によれば、吸気穴（３４ｉ）を通じて塵埃受け部（４０）の内部に空気の流れを生じさせて、吸引装置（４２）により生じた気流が吸気穴（３４ｉ）を通り、塵埃受け部（４０）の内部の塵埃を吸引しやすい構成となる。この結果、本発明によれば、塵埃の除去効率を一層向上させることができる。 In the dust automatic discharge configuration of the air conditioner of the present invention, the dust removing part (34) has a space on the suction opening side of the dust removing part (34) and opposite to the suction opening side of the dust removing part (34). An air intake hole (34i) is formed to communicate with the space of the above. According to this configuration, an air flow is generated inside the dust receiving portion (40) through the intake hole (34i), and the air flow generated by the suction device (42) passes through the intake hole (34i) and is passed through the dust receiving portion (34i). The structure is such that the dust inside (40) can be easily sucked. As a result, according to the present invention, the dust removal efficiency can be further improved.
　本発明の空気調和機においては、塵埃除去部（３４）における吸気穴（３４ｉ）が、ブラシ（３０）が配設されている上方に向けて開口した貫通穴形状である。また、吸気穴（３４ｉ）の下方には、誘導面（３４ｇ）が形成されている。この結果、ブラシ（３０）から掻き落とされた塵埃は、吸気穴（３４ｉ）を通り、誘導面（３４ｇ）により案内されて、塵埃除去部（３４）より吸引開口側に落下する構成となる。その結果、本発明によれば、ブラシ（３０）から掻き落とされた塵埃が、塵埃除去部（３４）よりも吸引開口側とは反対側の領域に落下することが抑えられている。 In the air conditioner of the present invention, the intake hole (34i) in the dust removing portion (34) has a through-hole shape that opens upward in which the brush (30) is arranged. Further, an induction surface (34 g) is formed below the intake hole (34i). As a result, the dust scraped off from the brush (30) passes through the intake hole (34i), is guided by the guide surface (34 g), and falls from the dust removing portion (34) to the suction opening side. As a result, according to the present invention, the dust scraped off from the brush (30) is suppressed from falling to the region opposite to the suction opening side of the dust removing portion (34).
　なお、本発明は前記の実施形態１の構成に限定されるものではなく、その他種々の態様の変形例で実施できる。例えば、前記の実施形態１では、塵埃除去部３４がブラシ３０の延在方向に移動することによってブラシ３０に付着する塵埃を掻き落とすように構成したが、本発明はこれに限定されない。例えば、本発明の空気調和機においては、ブラシ（３０）が塵埃除去部（３４）に対してブラシ（３０）の延在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してもよい。すなわち、塵埃除去部（３４）は、ブラシ（３０）に接触した状態でブラシ（３０）の延在方向に相対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してもよい。 It should be noted that the present invention is not limited to the configuration of the first embodiment, and can be implemented in various other modifications. For example, in the first embodiment, the dust removing portion 34 is configured to scrape off the dust adhering to the brush 30 by moving in the extending direction of the brush 30, but the present invention is not limited to this. For example, in the air conditioner of the present invention, the brush (30) moves in the extending direction of the brush (30) with respect to the dust removing portion (34) to scrape off the dust adhering to the brush (30). It may be configured as follows. That is, the dust removing unit (34) is configured to scrape off the dust adhering to the brush (30) by relatively moving in the extending direction of the brush (30) in contact with the brush (30). May be good.
　また、前記の実施形態１における構成では、塵埃除去部３４における吸気穴３４ｉが、上方に向けて開口する構成としたが、本発明はこれに限定されない。例えば、吸気穴（３４ｉ）は、塵埃除去部（３４）において、吸引開口側とは反対側の面である後方面に設けてもよい。このように塵埃除去部（３４）の後方面に貫通する吸気穴（３４ｉ）を設けた場合には、この吸気穴（３４ｉ）を通じて塵埃受け部（４０）の内部において空気の流れが直線又は略直線状に生じ、吸引装置（４２）により塵埃受け部（４０）の内部の塵埃を一層吸引しやすい構成となる。 Further, in the configuration according to the first embodiment, the intake hole 34i in the dust removing portion 34 is configured to open upward, but the present invention is not limited to this. For example, the intake hole (34i) may be provided on the rear surface of the dust removing portion (34), which is the surface opposite to the suction opening side. When the intake hole (34i) penetrating the rear surface of the dust removing portion (34) is provided in this way, the air flow is straight or substantially inside the dust receiving portion (40) through the intake hole (34i). It is generated in a linear shape, and the suction device (42) makes it easier to suck the dust inside the dust receiving portion (40).
　更に、前記の実施形態１では、ブラシ３０の延在方向と直交する方向にブラシ３０が揺動するように構成したが、本発明はこれに限定されない。例えば、本発明の空気調和機におけるブラシ（３０）は、必ずしもブラシ（３０）の延在方向と直交する方向に揺動する必要はなく、交差する方向や、平行な方向に揺動する構成においても、ブラシ（３０）に付着した塵埃を掻き落とすことができる構成であればよい。 Further, in the first embodiment, the brush 30 is configured to swing in a direction orthogonal to the extending direction of the brush 30, but the present invention is not limited to this. For example, the brush (30) in the air conditioner of the present invention does not necessarily have to swing in a direction orthogonal to the extending direction of the brush (30), and in a configuration in which the brush (30) swings in an intersecting direction or a parallel direction. However, any configuration may be used as long as it can scrape off the dust adhering to the brush (30).
　また、前述の実施形態１の構成において、塵埃除去部３４は、ブラシ３０の延在方向に対して直交する方向に延在する第１ブレード部（前方ブレード３４ａ及び後方ブレード３４ｂ）を有する構成としたが、本発明はこれに限定されない。例えば、本発明における塵埃除去部（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第１ブレード部として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。 Further, in the configuration of the first embodiment described above, the dust removing portion 34 has a configuration having a first blade portion (front blade 34a and rear blade 34b) extending in a direction orthogonal to the extending direction of the brush 30. However, the present invention is not limited to this. For example, the dust removing portion (34) in the present invention may have one blade or three or more blades as a first blade portion extending in a direction intersecting the extending direction of the brush (30). Good.
　更に、前述の実施形態１の構成において、塵埃除去部３４は、第１ブレード部の前方ブレード３４ａと後方ブレード３４ｂ、及び第２ブレード部の側方ブレード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したが、本発明はこれに限定されない。本発明の空気調和機においては、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してもよい。 Further, in the configuration of the first embodiment described above, the dust removing portion 34 is dust adhering to the brush 30 by the front blade 34a and the rear blade 34b of the first blade portion and the side blades 34e and 34f of the second blade portion. The present invention is not limited to this, although it is configured to scrape off. In the air conditioner of the present invention, 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). Good.
　なお、実施形態１の構成では、図１１において断面で示した誘導面３４ｇを平面として図示したが、本発明はこれに限定されない。例えば、本発明の構成においては、誘導面（３４ｇ）が、下方に延びる複数の溝形状の凹凸構造を有してもよい。このような構造とすることにより、ブラシ（３０）から掻き落とされた塵埃が誘導面（３４ｇ）に付着することを抑えることができ、塵埃の除去効率を一層向上させることができる。 In the configuration of the first embodiment, the guide surface 34 g shown in the cross section in FIG. 11 is shown as a plane, but the present invention is not limited to this. For example, in the configuration of the present invention, the guide surface (34 g) may have a plurality of groove-shaped uneven structures extending downward. With such a structure, it is possible to prevent the dust scraped off from the brush (30) from adhering to the guide surface (34 g), and it is possible to further improve the dust removal efficiency.
　前述の実施形態１においては、本発明の空気調和機として、所謂、壁面に取り付ける室内機と、屋外に設置する室外機とを有するセパレート型のエアコンディショナについて説明したが、本発明の空気調和機はこの構成に限定されるものではない。本発明の空気調和機としては、対象とする特定の空間における空気の温度、湿度、及び／又は清浄度等を調整するための空気調和機を含むものであり、例えば、室内機・室外機が一体化されたエアコンディショナ、空気清浄機、加湿器等の空気を調整するための各種機器が含まれる。 In the above-described first embodiment, as the air conditioner of the present invention, a separate type air conditioner having a so-called wall-mounted indoor unit and an outdoor unit installed outdoors has been described, but the air conditioner of the present invention has been described. The machine is not limited to this configuration. The air conditioner of the present invention includes an air conditioner for adjusting the temperature, humidity, and / or cleanliness of air in a specific space of interest, for example, an indoor unit / outdoor unit. It includes various devices for adjusting the air, such as an integrated air conditioner, air purifier, and humidifier.
　本発明は、添付図面を参照しながら好ましい実施の形態に関連して充分に記載されているが、この技術に熟練した人々にとっては種々の変形や修正は明白である。そのような変形や修正は、添付した請求の範囲による本発明の範囲から外れない限りにおいて、その中に含まれると理解されるべきである。 Although the present invention has been fully described in connection with preferred embodiments with reference to the accompanying drawings, various modifications and modifications are obvious to those skilled in the art. It should be understood that such modifications and modifications are included therein, as long as they do not deviate from the scope of the invention according to the appended claims.
　以上のように、本発明にかかる空気調和機は、塵埃の除去効率を向上させることができると共に、設置環境に応じて塵埃自動排出構成と塵埃手動排出構成とを切り替えることが可能な構成であるため、空気調和機として設置条件が緩和され汎用性の高いものとなる。 As described above, the air conditioner according to the present invention has a configuration capable of improving the dust removal efficiency and switching between an automatic dust discharge configuration and a manual dust discharge configuration according to the installation environment. Therefore, as an air conditioner, the installation conditions are relaxed and it becomes highly versatile.
