以下、本発明の空気調和機の実施例を図面を用いて説明する。まず、空気調和機の全体構成について図１及び図３を用いて説明する。   Hereinafter, embodiments of the air conditioner of the present invention will be described with reference to the drawings. First, the whole structure of an air conditioner is demonstrated using FIG.1 and FIG.3.

図１は空気調和機の全体構成図である。空気調和機１は、室内機２，室外機６、及び室内機２に操作信号を送信するリモコン５を備える。室内機２及び室外機６は接続配管８で接続される。室内機２は、筐体２１内に、後述する熱交換器３３等の内部構造体を備える。空気調和機１は、室内空気を空気吸込口２７から吸い込み、熱交換器３３で加熱，冷却，除湿等された室内空気を、空気吹出口２９から室内に吹き出すことにより、室内を空気調和する。   FIG. 1 is an overall configuration diagram of an air conditioner. The air conditioner 1 includes an indoor unit 2, an outdoor unit 6, and a remote controller 5 that transmits an operation signal to the indoor unit 2. The indoor unit 2 and the outdoor unit 6 are connected by a connection pipe 8. The indoor unit 2 includes an internal structure such as a heat exchanger 33 described later in the housing 21. The air conditioner 1 sucks room air from the air inlet 27 and blows out room air heated, cooled, dehumidified, etc. by the heat exchanger 33 into the room from the air outlet 29 to air-condition the room.

図３は室内機の側断面図である。室内機２は、室内空気を吸い込む空気吸込口２７を室内機２上部に備える。空気吸込口２７の下流側には、室内空気中の塵埃を除去するフィルター２３１が空気吸込口２７を覆うように配置される。フィルター２３１の下流であって、筐体２１の中央部には、略逆Ｖ字状に形成され熱交換器３３が配置される。熱交換器３３の下流には、熱交換器３３の幅と略等しい長さの貫流ファン方式の送風ファン３１１が配置される。熱交換器の下端部には露受皿３５が配置される。露受皿３５は、冷房運転時や除湿運転時に熱交換器３３に発生する凝縮水を受ける。露受皿３５に集められた凝縮水はドレン配管３７を通して室外に排出される。熱交換器３３の下流であって、室内機２の下部には、熱交換器３３で加熱，冷却，除湿等された室内空気を室内に吹き出す空気吹出口２９を備える。空気吹出口２９には、吹き出される空気を左右方向に偏向する左右風向板２９５、及び、上下方向に偏向する上下風向板２９１を備える。   FIG. 3 is a side sectional view of the indoor unit. The indoor unit 2 includes an air suction port 27 for sucking room air in the upper part of the indoor unit 2. A filter 231 that removes dust in room air is disposed downstream of the air suction port 27 so as to cover the air suction port 27. Downstream of the filter 231 and in the central part of the housing 21, a heat exchanger 33 is disposed in a substantially inverted V shape. A cross-flow fan type blower fan 311 having a length substantially equal to the width of the heat exchanger 33 is disposed downstream of the heat exchanger 33. A dew tray 35 is disposed at the lower end of the heat exchanger. The dew receiving tray 35 receives condensed water generated in the heat exchanger 33 during cooling operation or dehumidifying operation. The condensed water collected in the dew tray 35 is discharged outside through the drain pipe 37. An air outlet 29 is provided downstream of the heat exchanger 33 and below the indoor unit 2 to blow indoor air heated, cooled, or dehumidified by the heat exchanger 33 into the room. The air outlet 29 includes a left and right wind direction plate 295 that deflects the blown air in the left and right direction, and a vertical wind direction plate 291 that deflects the air in the vertical direction.

空気調和機１において、まず、送風ファン３１１を運転することで、室内空気を空気吸込口２７から室内機２内に吸い込む。その際、フィルター２３１により空気中の塵埃が除去される。その後、室内機２内に吸い込まれた室内空気は、熱交換器３３で加熱，冷却，除湿等されて、送風ファン３１１を介して、空気吹出口２９から室内に吹き出される。空気吹出口２９から室内に吹き出される調和された空気は、左右風向板２９５及び上下風向板２９１により、左右方向及び上下方向が偏向される。このようにして、室内空気を空気吸込口２７から吸い込み、熱交換器３３で加熱，冷却，除湿等された室内空気を空気吹出口２９から室内に吹き出すことにより、室内を空気調和する。   In the air conditioner 1, first, the blower fan 311 is operated to suck room air into the indoor unit 2 from the air suction port 27. At that time, dust in the air is removed by the filter 231. Thereafter, the indoor air sucked into the indoor unit 2 is heated, cooled, dehumidified, and the like by the heat exchanger 33 and blown into the room from the air outlet 29 via the blower fan 311. The conditioned air blown into the room from the air outlet 29 is deflected left and right and up and down by the left and right wind direction plates 295 and 291. In this way, room air is sucked from the air suction port 27, and the room air heated, cooled, dehumidified, etc. by the heat exchanger 33 is blown into the room from the air outlet 29, thereby air conditioning the room.

次に、フィルター２３１の清掃機構２３０について図２及び図４を用いて説明する。図２は室内機の内部上面図である。図４は清掃機構の斜視図である。   Next, the cleaning mechanism 230 of the filter 231 will be described with reference to FIGS. FIG. 2 is an internal top view of the indoor unit. FIG. 4 is a perspective view of the cleaning mechanism.

清掃機構２３０は、掃除用刷毛２６７と、フィルター２３１に捕集された塵埃を掃き取るように図２及び図４の左右方向（室内機２の長手方向）に掃除用刷毛２６７を移動させる移動機構２３３と、掃除用刷毛２６７により掃き取られた塵埃を収集する集塵機構２７０とを備える。   The cleaning mechanism 230 is a moving mechanism that moves the cleaning brush 267 in the left-right direction of FIG. 2 and FIG. 4 (longitudinal direction of the indoor unit 2) so as to sweep out dust collected by the filter 231 and the cleaning brush 267. 233 and a dust collecting mechanism 270 that collects dust swept by the cleaning brush 267.

移動機構２３３は、掃除用刷毛２６７を保持する刷毛保持部２６２と、刷毛保持部２６２を案内する案内枠２３４と、刷毛保持部２６２を移動させる移動用モータ２４２とを備える。案内枠２３４は、フィルター２３１の室内機２背面側にレール２３５を、フィルター２３１の室内機２前面側に推進軸を備える。   The moving mechanism 233 includes a brush holding portion 262 that holds the cleaning brush 267, a guide frame 234 that guides the brush holding portion 262, and a moving motor 242 that moves the brush holding portion 262. The guide frame 234 includes a rail 235 on the back side of the indoor unit 2 of the filter 231 and a propulsion shaft on the front side of the indoor unit 2 of the filter 231.

案内枠２３４は、刷毛保持部２６２に保持された掃除用刷毛２６７がフィルター２３１及び集塵機構２７０上を図２及び図４の左右方向に移動するように、フィルター２３１及び集塵機構２７０を囲うように配置される。尚、フィルター２３１を案内枠２３４に固定して、フィルター２３１と案内枠２３４を一体に構成するようにしてもよい。   The guide frame 234 surrounds the filter 231 and the dust collecting mechanism 270 so that the cleaning brush 267 held by the brush holding unit 262 moves on the filter 231 and the dust collecting mechanism 270 in the left-right direction in FIGS. Be placed. The filter 231 may be fixed to the guide frame 234, and the filter 231 and the guide frame 234 may be configured integrally.

推進軸２４３は多角形断面を有し、案内枠２３４に設けられた図示しない軸受に軸支される。推進軸２４３の一端は、図示しない歯車を介して、案内枠２３４に固定された移動用モータ２４２に連結される。推進軸２４３にはスクリュウ，キャリッジ２６１が緩挿され、スクリュウは案内枠２３４に設けられた、推進軸２４３と平行なラックに噛合している。刷毛保持部２６２は、推進軸２４３が保持するキャリッジ２６１とレール２３５とにより保持され、フィルター２３１を跨ぐように配置される。   The propulsion shaft 243 has a polygonal cross section, and is supported by a bearing (not shown) provided on the guide frame 234. One end of the propulsion shaft 243 is connected to a moving motor 242 fixed to the guide frame 234 via a gear (not shown). A screw and a carriage 261 are loosely inserted into the propulsion shaft 243, and the screw meshes with a rack provided on the guide frame 234 and parallel to the propulsion shaft 243. The brush holding unit 262 is held by the carriage 261 and the rail 235 held by the propelling shaft 243 and is disposed so as to straddle the filter 231.

このような移動機構２３３において、移動用モータ２４２を回転させることで、推進軸２４３が回転し、図２及び図４の左右方向にスクリュウが移動する。スクリュウの移動に伴って、キャリッジ２６１に保持された刷毛保持部２６２が図２及び図４の左右方向に移動する。これにより、刷毛保持部２６２に保持された掃除用刷毛２６７が、フィルター２３１に捕集された塵埃を掃き取るようにフィルター２３１上を移動する。尚、移動用モータ２４２の回転方向を逆回転にすることにより、キャリッジ２６１の移動方向を変更することができる。   In such a moving mechanism 233, by rotating the moving motor 242, the propulsion shaft 243 rotates, and the screw moves in the left-right direction in FIGS. As the screw moves, the brush holding portion 262 held by the carriage 261 moves in the left-right direction in FIGS. As a result, the cleaning brush 267 held by the brush holding unit 262 moves on the filter 231 so as to sweep up dust collected by the filter 231. Note that the moving direction of the carriage 261 can be changed by reversing the rotating direction of the moving motor 242.

次に、集塵機構２７０について、図５〜図８を用いて説明する。図５は集塵機構の上面図、図６は集塵機構の斜視図、図７は集塵機構の断面図、図８は集塵機構の櫛歯の拡大図である。   Next, the dust collection mechanism 270 will be described with reference to FIGS. 5 is a top view of the dust collecting mechanism, FIG. 6 is a perspective view of the dust collecting mechanism, FIG. 7 is a sectional view of the dust collecting mechanism, and FIG. 8 is an enlarged view of comb teeth of the dust collecting mechanism.

集塵機構２７０は、フィルター２３１の方向に歯先が向かう第１櫛歯２７１と、フィルター２３１と第１櫛歯２７１との間に位置し第１櫛歯２７１の方向に歯先が向かう第２櫛歯２７３と、第１櫛歯２７１と第２櫛歯２７３の下方に位置し掃除用刷毛により掃き取られた塵埃を貯留する集塵容器２８４とを有する。つまり、集塵機構２７０は、収容開口２７０ｂを挟んで対向するように第１櫛歯２７１及び第２櫛歯２７３を備える。   The dust collection mechanism 270 includes a first comb tooth 271 whose tooth tips are directed toward the filter 231 and a second comb positioned between the filter 231 and the first comb teeth 271 and whose tooth tips are directed toward the first comb teeth 271. Teeth 273, and a dust collecting container 284 that is located below the first comb teeth 271 and the second comb teeth 273 and stores the dust swept away by the cleaning brush. That is, the dust collection mechanism 270 includes the first comb teeth 271 and the second comb teeth 273 so as to face each other with the accommodation opening 270b interposed therebetween.

収容開口２７０ｂは掃除用刷毛２６７の毛束２６９が収まる大きさとする。第１櫛歯２７１の歯先を結ぶ線（第１包絡線２７１ｄ）及び第２櫛歯２７３の歯先を結ぶ線（第２包絡線２７３ｄ）は、掃除用刷毛２６７の刷毛幅γ方向（掃除用刷毛２６７の移動方向）に対して傾斜する（第１櫛歯２７１の歯先は傾斜角αで交差する。また、第２櫛歯２７３の歯先は傾斜角βで交差する）。   The accommodation opening 270b has a size that can accommodate the hair bundle 269 of the cleaning brush 267. The line connecting the tooth tips of the first comb teeth 271 (first envelope 271d) and the line connecting the tooth tips of the second comb teeth 273 (second envelope 273d) are in the direction of the brush width γ of the cleaning brush 267 (cleaning) The tooth tips of the first comb teeth 271 intersect at an inclination angle α. The tooth tips of the second comb teeth 273 intersect at an inclination angle β.

第１櫛歯２７１の歯先と第２櫛歯２７３の歯先が互いにずれるように配置する。つまり、第１櫛歯２７１の歯先は第２櫛歯２７３の歯底と対向し、第２櫛歯２７３の歯先は第１櫛歯２７１の歯底に対向するように配置する。このように、第１櫛歯２７１の歯先と第２櫛歯２７３の歯先が互いにずれるように配置するので、掃除用刷毛２６７の進行方向により、第１櫛歯２７１の歯先と第２櫛歯２７３の歯先がそれぞれ掃除用刷毛２６７を梳く位置がずれるので、掃除用刷毛２６７をより細かなピッチで梳くことができる。掃除用刷毛２６７をより細かなピッチで梳くことにより、掃除用刷毛２６７に付着した塵埃をより除去することができる。   The tooth tips of the first comb teeth 271 and the tooth tips of the second comb teeth 273 are arranged so as to be shifted from each other. That is, the tooth tips of the first comb teeth 271 are arranged to face the bottom of the second comb teeth 273, and the tooth tips of the second comb teeth 273 are arranged to face the tooth bottom of the first comb teeth 271. Thus, since the tooth tip of the first comb tooth 271 and the tooth tip of the second comb tooth 273 are arranged so as to deviate from each other, the tooth tip of the first comb tooth 271 and the second tooth tip of the second comb tooth 271 are moved according to the traveling direction of the cleaning brush 267. Since the positions of the tooth tips of the comb teeth 273 are different from each other, the cleaning brush 267 can be combed at a finer pitch. By dusting the cleaning brush 267 at a finer pitch, dust attached to the cleaning brush 267 can be further removed.

また、フィルター２３１と第２櫛歯２７３との間に、毛先が第２櫛歯２７３の方向に傾斜した第２除去ブラシ２７５を備える。この第２除去ブラシ２７５は、第１櫛歯２７１の歯先（又は第２櫛歯２７３の歯先）と同様に、掃除用刷毛２６７の刷毛幅γ方向（掃除用刷毛２６７の移動方向）に対して傾斜する。   Further, a second removal brush 275 having a hair tip inclined in the direction of the second comb tooth 273 is provided between the filter 231 and the second comb tooth 273. The second removal brush 275 is arranged in the brush width γ direction of the cleaning brush 267 (moving direction of the cleaning brush 267) in the same manner as the tooth tip of the first comb tooth 271 (or the tooth tip of the second comb tooth 273). Inclines against.

掃除用刷毛２６７は、掃除用刷毛２６７の進行方向に、刷毛押え２６８を備える。刷毛押え２６８により、掃除用刷毛２６７の変形を抑制する。   The cleaning brush 267 includes a brush presser 268 in the traveling direction of the cleaning brush 267. The brush presser 268 suppresses the deformation of the cleaning brush 267.

次に、清掃機構の構成及び動作について図９を用いて説明する。図９は清掃動作説明図である。   Next, the configuration and operation of the cleaning mechanism will be described with reference to FIG. FIG. 9 is an explanatory view of the cleaning operation.

フィルター２３１の側方には、清掃動作が行われていないときに掃除用刷毛２６７が待機する待機位置（図９Ａ）が位置する。   A standby position (FIG. 9A) where the cleaning brush 267 waits when the cleaning operation is not performed is located on the side of the filter 231.

清掃動作が開始されると、移動機構２３３により、待機位置に待機していた掃除用刷毛２６７をフィルター２３１に向かって移動させる。このとき、掃除用刷毛２６７の毛先は、凹部となる待機位置の開放状態から傾斜部を通って、待機位置より少し高めに位置するフィルター２３１面に徐々に毛先を曲げながら乗り上げ、フィルター２３１と摺接する。フィルター２３１に摺接した掃除用刷毛２６７は、さらに集塵機構２７０の方向にフィルター２３１を移動してフィルター２３１を掃引し（図９Ｃ）、塵埃２３６を掃き取る。   When the cleaning operation is started, the cleaning mechanism 233 moves the cleaning brush 267 waiting at the standby position toward the filter 231. At this time, the bristles of the cleaning brush 267 run from the open state of the standby position, which is a recess, through the inclined portion, and gradually get on the surface of the filter 231 positioned slightly higher than the standby position while gradually bending the bristles. And slid. The cleaning brush 267 in sliding contact with the filter 231 further moves the filter 231 in the direction of the dust collection mechanism 270 to sweep the filter 231 (FIG. 9C), and sweeps the dust 236.

フィルター２３１を掃引した掃除用刷毛２６７は、掃き取った塵埃２３６と共に集塵機構２７０に向かう（図９Ｄ）。塵埃２３６を掃き取った掃除用刷毛２６７は、掃除用刷毛２６７が折返位置２７０ａ（図９Ｊ）で折り返して集塵機構２７０を往復する際に、第１櫛歯２７１及び第２櫛歯２７３により梳かれて、塵埃２３６を分離し集塵容器２８４内に移動させる。具体的には、掃除用刷毛２６７をフィルター２３１から第１櫛歯２７１に向かって移動させることにより、掃除用刷毛２６７によりフィルター２３１から掃き取られた塵埃を第１櫛歯２７１で梳いて集塵容器２８４に移送させ、その後、折返位置２７０ａ（図９Ｊ）反転して、掃除用刷毛２６７を第１櫛歯２７１から第２櫛歯２７３に向かって移動させることにより、掃除用刷毛２６７によりフィルター２３１から掃き取られた塵埃を第２櫛歯２７３で梳いて集塵容器２８４に移送させる。   The cleaning brush 267 that has swept the filter 231 goes to the dust collecting mechanism 270 together with the dust 236 that has been swept away (FIG. 9D). The cleaning brush 267 that has wiped off the dust 236 is beaten by the first comb teeth 271 and the second comb teeth 273 when the cleaning brush 267 is folded back at the folding position 270a (FIG. 9J) and reciprocates the dust collecting mechanism 270. Thus, the dust 236 is separated and moved into the dust collecting container 284. Specifically, by moving the cleaning brush 267 from the filter 231 toward the first comb teeth 271, the dust swept from the filter 231 by the cleaning brush 267 is scattered by the first comb teeth 271 to collect dust. The cleaning brush 267 is moved from the first comb teeth 271 toward the second comb teeth 273 by moving the container 284 to the container 284 and then turning over the folding position 270a (FIG. 9J). The dust that has been swept away from the dust is spread by the second comb teeth 273 and transferred to the dust collecting container 284.

次に、第１櫛歯及び第２櫛歯の働きについて図１０〜図１９を用いて説明する。図１０〜図１９は刷毛動作説明図である。   Next, functions of the first comb teeth and the second comb teeth will be described with reference to FIGS. 10 to 19 are explanatory views of the brush operation.

図１０に示すように、集塵機構２７０がフィルター２３１の側方に設けられる。刷毛保持部２６２の移動に伴って、フィルター２３１に摺接して掃除用刷毛２６７が掃き集めたフィルター２３１上の塵埃２３６は、第２除去ブラシ２７５及び第２櫛歯２７３を通過する。上述したように、第２除去ブラシ２７５は、毛先が第２櫛歯２７３の方向に傾斜しているため、掃除用刷毛２６７がフィルター２３１から第２櫛歯２７３に向かって移動する方向に対して順目となる。従って、掃除用刷毛２６７により掃き取られた塵埃２３６は、第２除去ブラシ２７５に付着せず、第２櫛歯２７３を通過して、収容開口２７０ｂに至る。   As shown in FIG. 10, a dust collection mechanism 270 is provided on the side of the filter 231. As the brush holding portion 262 moves, the dust 236 on the filter 231 slidably brought into contact with the filter 231 and swept up by the cleaning brush 267 passes through the second removal brush 275 and the second comb teeth 273. As described above, since the bristles of the second removal brush 275 are inclined in the direction of the second comb teeth 273, the cleaning brush 267 moves in the direction from the filter 231 toward the second comb teeth 273. It becomes order. Accordingly, the dust 236 swept by the cleaning brush 267 does not adhere to the second removal brush 275, passes through the second comb teeth 273, and reaches the accommodation opening 270b.

その後、図１１に示すように、第２櫛歯２７３を通過した掃除用刷毛２６７は、収容開口２７０ｂにおいて毛先が開放されて毛束２６９が下向きになり、掃除用刷毛２６７に掃き取られた塵埃２３６の一部が集塵容器２８４に落下する。   After that, as shown in FIG. 11, the cleaning brush 267 that passed through the second comb teeth 273 was swept away by the cleaning brush 267 with the bristles 269 facing downward at the accommodation opening 270b and the bristles 269 facing downward. Part of the dust 236 falls into the dust collecting container 284.

図１２に示すように、落下しなかった塵埃２３６は掃除用刷毛２６７の毛束２６９に付着したまま第１櫛歯２７１に到達し、塵埃２３６の一部は第１櫛歯２７１に梳き取られて集塵容器２８４に落下する。集塵容器２８４に落下しなかった塵埃２３６の一部は第１櫛歯２７１に付着し、他の塵埃２３６は掃除用刷毛２６７に付着し続ける。   As shown in FIG. 12, the dust 236 that has not dropped reaches the first comb teeth 271 while adhering to the hair bundle 269 of the cleaning brush 267, and a part of the dust 236 is scraped off by the first comb teeth 271. And fall into the dust collecting container 284. Part of the dust 236 that has not fallen into the dust collecting container 284 adheres to the first comb teeth 271 and the other dust 236 continues to adhere to the cleaning brush 267.

ここで、第１櫛歯２７１は、上述したように、掃除用刷毛２６７の刷毛幅方向に対して傾斜するので、掃除用刷毛２６７が第１櫛歯２７１の歯先に接触する際、掃除用刷毛２６７の一部が第１櫛歯２７１に接触し、その後、掃除用刷毛２６７の移動にともなって、掃除用刷毛２６７と第１櫛歯２７１の接触部分が増大する。従って、移動機構の負荷は、掃除用刷毛２６７が第１櫛歯２７１と接触してから徐々に増加し、その後、掃除用刷毛２６７と第１櫛歯２７１との接触の増加に従って、移動機構の負荷も増加する。移動機構の負荷が急激には増大しないので、掃除用刷毛２６７と第１櫛歯２７１と衝撃が和らげられ、騒音，振動の発生が抑制される。また、振動部の磨耗も抑制されるので信頼性を向上できる。尚、説明は省略するが、第２櫛歯２７３も掃除用刷毛２６７の刷毛幅方向に対して傾斜しており、同様の効果を奏する。   Here, since the first comb teeth 271 are inclined with respect to the brush width direction of the cleaning brush 267 as described above, when the cleaning brush 267 contacts the tooth tips of the first comb teeth 271, A part of the brush 267 comes into contact with the first comb teeth 271, and then the contact portion between the cleaning brush 267 and the first comb teeth 271 increases with the movement of the cleaning brush 267. Therefore, the load of the moving mechanism gradually increases after the cleaning brush 267 comes into contact with the first comb teeth 271, and thereafter, as the contact between the cleaning brush 267 and the first comb teeth 271 increases, The load also increases. Since the load of the moving mechanism does not increase abruptly, the cleaning brush 267 and the first comb teeth 271 and the impact are alleviated, and the generation of noise and vibration is suppressed. Further, since the wear of the vibration part is suppressed, the reliability can be improved. In addition, although description is abbreviate | omitted, the 2nd comb tooth 273 is also inclined with respect to the brush width direction of the cleaning brush 267, and there exists the same effect.

その後、図１３に示すように、第１櫛歯２７１を通過した掃除用刷毛２６７は、集塵機構２７０の側方の折返位置２７０ａ（図９Ｊ）まで進み、反転する。   Thereafter, as shown in FIG. 13, the cleaning brush 267 that has passed through the first comb teeth 271 advances to the side folding position 270 a (FIG. 9J) of the dust collection mechanism 270 and is reversed.

図１４に示すように、掃除用刷毛２６７は、折返位置２７０ａから収納開口２７０ｂに向かって第１櫛歯２７１上を移動する。このとき、図１５に示すように、掃除用刷毛２６７は、第１櫛歯２７１に付着している塵埃２３６を掃き取り、塵埃２３６の大部分を集塵容器２８４に落として収納開口２７０ｂに達する。   As shown in FIG. 14, the cleaning brush 267 moves on the first comb teeth 271 from the folding position 270a toward the storage opening 270b. At this time, as shown in FIG. 15, the cleaning brush 267 sweeps out the dust 236 adhering to the first comb teeth 271 and drops most of the dust 236 into the dust collecting container 284 to reach the storage opening 270b. .

さらに、図１６に示すように、掃除用刷毛２６７に付着している塵埃２３６を、第２櫛歯２７３で梳き取る。このとき、第２櫛歯２７３により掃き取られた塵埃２３６の一部は集塵容器に落下し、僅かではあるが塵埃２３６の一部は第２櫛歯２７３に付着し続ける。このようにして、掃除用刷毛２６７により掃き取られたほとんどの塵埃２３６は集塵容器２８４に落下する。   Further, as shown in FIG. 16, the dust 236 adhering to the cleaning brush 267 is scraped off by the second comb teeth 273. At this time, part of the dust 236 that has been swept away by the second comb teeth 273 falls to the dust collecting container, and a part of the dust 236 continues to adhere to the second comb teeth 273. In this way, most of the dust 236 swept by the cleaning brush 267 falls into the dust collecting container 284.

次に、図１７に示すように、掃除用刷毛２６７を第２除去ブラシ２７５に摺接させる。第２除去ブラシ２７５の毛先の方向は掃除用刷毛２６７の移動方向と逆の逆目になるので、掃除用刷毛２６７に僅かに付着している塵埃２３６が、第２除去ブラシ２７５により除去される。このようにして、掃除用刷毛２６７に付着した塵埃がフィルター２３１に戻らないようにする。一方、第２除去ブラシ２７５により除去された塵埃は第２除去ブラシ２７５に留まるが、次回の清掃動作において掃除用刷毛２６７がフィルター２３１から集塵機構２７０に向かって第２除去ブラシ２７５上を移動する際に、第２除去ブラシ２７５の毛先は第２櫛歯２７３の方向に傾斜しているため、フィルター２３１で掃き取られた塵埃とともに第２除去ブラシ２７５に留まる塵埃も掃き取られ、集塵容器に移送される。このような第２除去ブラシにより、簡易な構造で、第２除去ブラシ上を往復運動させるのみで、掃除用刷毛２６７に付着した塵埃をフィルター２３１に戻るのを防止できるとともに、第２除去ブラシにより除去された塵埃を次回の清掃動作の際に集塵容器に移送することができる。   Next, as shown in FIG. 17, the cleaning brush 267 is brought into sliding contact with the second removal brush 275. Since the direction of the hair tip of the second removal brush 275 is opposite to the direction of movement of the cleaning brush 267, the dust 236 slightly adhered to the cleaning brush 267 is removed by the second removal brush 275. The In this way, dust attached to the cleaning brush 267 is prevented from returning to the filter 231. On the other hand, although the dust removed by the second removal brush 275 remains on the second removal brush 275, the cleaning brush 267 moves on the second removal brush 275 from the filter 231 toward the dust collecting mechanism 270 in the next cleaning operation. At this time, since the bristles of the second removal brush 275 are inclined in the direction of the second comb teeth 273, the dust remaining on the second removal brush 275 is also swept away together with the dust swept away by the filter 231. Transferred to a container. With such a second removal brush, the dust attached to the cleaning brush 267 can be prevented from returning to the filter 231 simply by reciprocating on the second removal brush with a simple structure, and the second removal brush The removed dust can be transferred to the dust collecting container in the next cleaning operation.

さらに、第２除去ブラシ２７５は、第１櫛歯２７１の歯先と同様に、掃除用刷毛２６７の刷毛幅方向に対して傾斜するので、掃除用刷毛２６７が第２櫛歯２７３から第２除去ブラシ２７５に向かって移動して、掃除用刷毛２６７が第２除去ブラシ２７５に接触する際、掃除用刷毛２６７の一部が第２除去ブラシ２７５に接触し、その後、掃除用刷毛２６７の移動にともなって、掃除用刷毛２６７と第２除去ブラシ２７５の接触部分が増大する。従って、掃除用刷毛２６７が第２除去ブラシ２７５と接触してから移動機構の負荷が徐々に増加し、その後、掃除用刷毛２６７と第２除去ブラシとの接触の増加に従って、移動機構の負荷も増加する。移動機構の負荷が急激には増大しないので、掃除用刷毛２６７と第２除去ブラシとの衝撃が和らげられ、騒音，振動の発生が抑制される。また、振動部の磨耗も抑制されるので信頼性を向上できる。   Furthermore, since the second removal brush 275 is inclined with respect to the brush width direction of the cleaning brush 267 in the same manner as the tooth tip of the first comb tooth 271, the cleaning brush 267 is second removed from the second comb tooth 273. When the cleaning brush 267 moves toward the brush 275 and contacts the second removal brush 275, a part of the cleaning brush 267 contacts the second removal brush 275, and then the cleaning brush 267 moves. Along with this, the contact portion between the cleaning brush 267 and the second removal brush 275 increases. Accordingly, the load of the moving mechanism gradually increases after the cleaning brush 267 contacts the second removal brush 275, and then the load of the moving mechanism also increases as the contact between the cleaning brush 267 and the second removal brush increases. To increase. Since the load of the moving mechanism does not increase abruptly, the impact of the cleaning brush 267 and the second removal brush is reduced, and the generation of noise and vibration is suppressed. Further, since the wear of the vibration part is suppressed, the reliability can be improved.

その後、図１９に示すように、掃除用刷毛２６７を回転させて、毛先をフィルター２３１から離して、待機位置（図９Ａ）まで移動させる。つまり、掃除用刷毛２６７を第２除去ブラシ２７５から待機位置（図９Ａ）まで移動させる際は、掃除用刷毛２６７をフィルター２３１に接触させずにフィルター２３１上方を移動させる。掃除用刷毛２６７の毛先をフィルター２３１から離して移動させるので、掃除用刷毛２６７を移動させる際のフィルター２３１との抵抗が少なくなり、掃除用刷毛２６７の移動速度を上げて移動させることで、清掃時間を短縮することができる。また、掃除用刷毛２６７とフィルター２３１との接触による磨耗も抑制することができる。その後、待機位置（図９Ａ）まで移動したら、掃除用刷毛２６７を回転させて、毛先を下方に向けて清掃動作を終了し、次回の清掃まで待機する。   After that, as shown in FIG. 19, the cleaning brush 267 is rotated to move the hair tip away from the filter 231 and move it to the standby position (FIG. 9A). That is, when the cleaning brush 267 is moved from the second removal brush 275 to the standby position (FIG. 9A), the cleaning brush 267 is moved above the filter 231 without contacting the filter 231. Since the tip of the cleaning brush 267 is moved away from the filter 231, the resistance with the filter 231 when the cleaning brush 267 is moved is reduced, and the cleaning brush 267 is moved at a higher moving speed. Cleaning time can be shortened. Also, wear due to contact between the cleaning brush 267 and the filter 231 can be suppressed. After that, when moving to the standby position (FIG. 9A), the cleaning brush 267 is rotated, the hair ends are directed downward, the cleaning operation is finished, and the next cleaning is waited.

このように、本実施例の空気調和機は、空気吸込口及び空気吹出口を有する筐体と、筐体内に配置された熱交換器と、熱交換器の空気吸い込み側に配置されたフィルターと、室内空気を空気吸込口より吸い込みフィルター及び熱交換器を通してから空気吹出口より吹き出す送風ファンと、フィルターに捕集された塵埃を除去する清掃装置とを備え、清掃装置は、フィルターに捕集された塵埃を掃き取る掃除用刷毛と、フィルターの方向に歯先が向かう第１櫛歯と、フィルターと第１櫛歯との間に位置し第１櫛歯の方向に歯先が向かう第２櫛歯と、第１櫛歯と第２櫛歯との下方に位置し掃除用刷毛により掃き取られた塵埃を貯留する集塵容器とを有する。このような本実施例の空気調和機によれば、固定された第１櫛歯及び第２櫛歯並びに集塵容器上を掃除用刷毛を往復移動させるのみで、掃除用刷毛を第１櫛歯及び第２櫛歯で梳くこと及び掃除用刷毛を第１櫛歯及び第２櫛歯の間の収納開口で解放することを繰り返して、掃除用刷毛に付着した塵埃を集塵容器に移送することができるので、より簡易な構造で信頼性が高く且つ装置の小型化を可能とした清掃機構を備えた空気調和機を提供することができる。   Thus, the air conditioner of the present embodiment includes a housing having an air inlet and an air outlet, a heat exchanger disposed in the housing, and a filter disposed on the air suction side of the heat exchanger. , Equipped with a blower fan that sucks indoor air from the air inlet and blows it out from the air outlet after passing through the filter and heat exchanger, and a cleaning device that removes dust collected by the filter, and the cleaning device is collected by the filter A cleaning brush that sweeps away dust, a first comb tooth whose tip is directed toward the filter, and a second comb that is located between the filter and the first comb tooth and is directed toward the first comb tooth And a dust collecting container for storing dust that is located below the first comb teeth and the second comb teeth and is swept away by the cleaning brush. According to such an air conditioner of this embodiment, the cleaning brush is moved to the first comb teeth only by reciprocating the cleaning brush on the fixed first comb teeth and second comb teeth and the dust collecting container. And repeating the combing with the second comb teeth and releasing the cleaning brush at the storage opening between the first comb teeth and the second comb teeth, and transferring the dust adhering to the cleaning brush to the dust collecting container Therefore, it is possible to provide an air conditioner equipped with a cleaning mechanism that has a simpler structure, is highly reliable, and can be downsized.

尚、本実施例においては、第１櫛歯２７１及び第２櫛歯２７３で一回ずつ掃除用刷毛２６７を梳いたが、その後、図１８に示すように、掃除用刷毛２６７をフィルター２３１の手前（図９Ｄ）で反転させ、図１０〜図１８の動作を複数回繰り返してもよい。これにより、１往復の清掃動作で取りきれなかった塵埃でも掃除用刷毛２６７から分離できるので、掃除用刷毛２６７に付着した塵埃２３６をより除去することができる。   In the present embodiment, the cleaning brush 267 is squeezed once with the first comb teeth 271 and the second comb teeth 273. Thereafter, the cleaning brush 267 is placed in front of the filter 231 as shown in FIG. (FIG. 9D) may be reversed, and the operations of FIGS. 10 to 18 may be repeated a plurality of times. Accordingly, even dust that cannot be removed by one reciprocating cleaning operation can be separated from the cleaning brush 267, so that the dust 236 adhering to the cleaning brush 267 can be further removed.

また、本実施例においては、清掃装置が運転停止しているとき、掃除用刷毛２６７を図９Ａの待機位置で待機させたが、掃除用刷毛２６７を収納開口２７０ｂ（図９Ｇ、第１櫛歯２７１と第２櫛歯２７３との間）で待機させることもできる。この場合、待機時に収納開口２７０ｂが掃除用刷毛２６７の毛束２６９で塞がれるので、集塵機構２７０からの意図しない塵埃の飛散を防止できる。また、掃除用刷毛２６７の毛先が開放されているので、掃除用刷毛２６７の毛先が曲がるのを防止できる。   Further, in this embodiment, when the cleaning device is stopped, the cleaning brush 267 is put on standby at the standby position in FIG. 9A, but the cleaning brush 267 is placed in the storage opening 270b (FIG. 9G, first comb teeth). 271 and the second comb teeth 273). In this case, the storage opening 270b is blocked by the bristle bundle 269 of the cleaning brush 267 during standby, so that unintended dust scattering from the dust collection mechanism 270 can be prevented. Further, since the tip of the cleaning brush 267 is open, the tip of the cleaning brush 267 can be prevented from being bent.

尚、フィルター２３１から折返位置２７０ａまで、掃除用刷毛２６７が摺接するフィルター２３１，第１櫛歯２７１，第２櫛歯２７３等の上面を同じ高さの平面にしてもよい。このように構成することにより、収納開口２７０ｂ面をフィルター２３１上面の延長上に置くことができ、掃除用刷毛２６７でフィルター２３１上を掃引した後に、引き続き、掃除用刷毛２６７を同一平面状で移動させて第１櫛歯２７１及び第２櫛歯２７３に摺接させることができる。掃除用刷毛２６７を同一平面状で移動させるので、掃除用刷毛２６７の移動機構が単純化でき、掃除用刷毛２６７を立体的に移動させる必要がないのでスペースも節約できる。   Note that the upper surfaces of the filter 231, the first comb teeth 271 and the second comb teeth 273, etc., with which the cleaning brush 267 is slidably contacted from the filter 231 to the folding position 270a may be flat surfaces having the same height. With this configuration, the surface of the storage opening 270b can be placed on an extension of the upper surface of the filter 231, and after the cleaning brush 267 sweeps over the filter 231, the cleaning brush 267 continues to move in the same plane. Thus, the first comb teeth 271 and the second comb teeth 273 can be brought into sliding contact with each other. Since the cleaning brush 267 is moved in the same plane, the moving mechanism of the cleaning brush 267 can be simplified, and it is not necessary to move the cleaning brush 267 in three dimensions, so that space can be saved.

次に、図２０を用いて、第１除去ブラシをさらに設けた第２の実施例について説明する。図２０は第１除去ブラシを設けた場合の集塵機構の断面図である。   Next, a second embodiment in which a first removal brush is further provided will be described with reference to FIG. FIG. 20 is a cross-sectional view of the dust collection mechanism when the first removal brush is provided.

本実施例においては、第１櫛歯２７１と掃除用刷毛２６７の折返位置２７０ａとの間、つまり、第１櫛歯２７１に対してフィルター２３１と反対側に、毛先が第１櫛歯２７１の方向に傾斜した第１除去ブラシ２７４を備える。   In this embodiment, the tip of the first comb tooth 271 is located between the first comb tooth 271 and the folding position 270a of the cleaning brush 267, that is, on the opposite side of the filter 231 with respect to the first comb tooth 271. A first removal brush 274 inclined in the direction is provided.

掃除用刷毛２６７が第１櫛歯２７１から折返位置２７０ａに向かって移動する際に、第１除去ブラシ２７４の毛先が第１櫛歯２７１の方向に傾斜しているため、第１櫛歯２７１で梳き落とされなかった塵埃が第１除去ブラシ２７４に付着する。一方、第１除去ブラシ２７４により除去された塵埃は第１除去ブラシ２７４に留まるが、掃除用刷毛２６７が反転して折返位置２７０ａから第１櫛歯２７１に向かって移動する際に、第１除去ブラシ２７４の毛先が第１櫛歯２７１の方向に傾斜しているため、第１除去ブラシ２７４に留まる塵埃が掃除用刷毛２６７により掃き取られ、収納開口２から集塵容器に移送される。このような第１除去ブラシにより、簡易な構造で、第１除去ブラシ上で掃除用刷毛２６７を往復運動させるのみで、掃除用刷毛２６７から塵埃をより除去することができる。   When the cleaning brush 267 moves from the first comb tooth 271 toward the folding position 270a, the hair tip of the first removal brush 274 is inclined in the direction of the first comb tooth 271. The dust that has not been scraped off by the dust adheres to the first removal brush 274. On the other hand, the dust removed by the first removal brush 274 remains on the first removal brush 274. However, when the cleaning brush 267 is reversed and moves from the folding position 270a toward the first comb teeth 271, the first removal brush 274 removes the dust. Since the bristles of the brush 274 are inclined in the direction of the first comb teeth 271, the dust remaining on the first removal brush 274 is swept away by the cleaning brush 267 and transferred from the storage opening 2 to the dust collecting container. With such a first removal brush, dust can be further removed from the cleaning brush 267 simply by reciprocating the cleaning brush 267 on the first removal brush with a simple structure.

尚、詳細な説明は省略するが、第１除去ブラシ２７４も第２除去ブラシと同様に、掃除用刷毛２６７の刷毛幅方向に対して傾斜する。従って、移動機構の負荷が急激に増大せず、掃除用刷毛２６７と第１除去ブラシとの衝撃が和らげられ、騒音，振動の発生が抑制される。また、振動部の磨耗も抑制されるので信頼性を向上できる。   Although not described in detail, the first removal brush 274 is also inclined with respect to the brush width direction of the cleaning brush 267 in the same manner as the second removal brush. Therefore, the load of the moving mechanism does not increase rapidly, the impact of the cleaning brush 267 and the first removal brush is reduced, and the generation of noise and vibration is suppressed. Further, since the wear of the vibration part is suppressed, the reliability can be improved.

次に、図２１を用いて、第１櫛歯及び／又は第２櫛歯の歯先に、集塵容器側に向いた突起を有する第３の実施例について説明する。図２１は第１櫛歯及び第２櫛歯の歯先に集塵容器側に向いた突起を設けた場合の集塵機構の断面図である。   Next, with reference to FIG. 21, a description will be given of a third embodiment in which the first comb teeth and / or the second comb teeth have protrusions facing the dust collecting container. FIG. 21 is a cross-sectional view of the dust collection mechanism when protrusions facing the dust collection container are provided on the tips of the first comb teeth and the second comb teeth.

本実施例においては、第１櫛歯２７１及び第２櫛歯２７３の歯先の下側に突起２７１ａ，２７３ａを設ける。掃除用刷毛２６７がそれぞれ第１櫛歯２７１及び第２櫛歯２７３の歯底から歯先に向けて移動するときに、歯と歯の間に入り込んだ掃除用刷毛２６７の毛先に付着していた塵埃を、突起２７１ａ，２７３ａに引っ掛けて掃除用刷毛２６７から分離する。突起２７１ａ，２７３ａにより掃除用刷毛２６７から分離した一部の塵埃は、重力により集塵容器に落下する。突起２７１ａ，２７３ａにより掃除用刷毛２６７から分離したが第１櫛歯２７１又は第２櫛歯２７３の歯先に付着した塵埃も、掃除用刷毛２６７の往復運動の際に、歯と歯の間に入り込んだ掃除用刷毛２６７の毛先に引っ掛かり集塵容器に落下する。このようにして、簡易な構造で、掃除用刷毛２６７に付着した塵埃をさらに除去することができる。   In the present embodiment, the protrusions 271a and 273a are provided on the lower sides of the first comb teeth 271 and the second comb teeth 273. When the cleaning brush 267 moves from the bottom of the first comb tooth 271 and the second comb tooth 273 toward the tooth tip, the cleaning brush 267 adheres to the tip of the cleaning brush 267 that has entered between the teeth. The collected dust is hooked on the protrusions 271a and 273a and separated from the cleaning brush 267. Part of the dust separated from the cleaning brush 267 by the protrusions 271a and 273a falls into the dust collecting container due to gravity. Dust that has been separated from the cleaning brush 267 by the protrusions 271a and 273a but adhered to the teeth of the first comb tooth 271 or the second comb tooth 273 is also between the teeth during the reciprocating motion of the cleaning brush 267. The cleaning brush 267 that has entered is caught on the tip of the brush 267 and dropped into the dust collecting container. In this way, dust attached to the cleaning brush 267 can be further removed with a simple structure.
