Is connected. The suction device 44 is a device that sucks dust in the discharge passage 42. At the other end of the discharge passage 42, an opening 42A is provided.
　図６は、吸引装置４４に関連する部品を示す側面図である。図６に示すように、吸引装置４４は、吸引管４６と、吸引管４６内に吸引力を発生させる吸引ファン４８とを備えている。吸引管４６の一端部は塵埃回収部３８の一端部に接続され、吸引管４６の他端部４６Ａは開口している。吸引管４６の他端部４６Ａは、吸引管４６内を通る塵埃を室外に排出できるように、一端が室外に開口した排気ホース（図示せず）に接続される。吸引ファン４８は、塵埃受け部３６と塵埃回収部３８とで排出通路４２が形成されたときに駆動され、排出通路４２内の塵埃を吸引する。 FIG. 6 is a side view showing components related to the suction device 44. As shown in FIG. 6, the suction device 44 includes a suction pipe 46 and a suction fan 48 that generates a suction force in the suction pipe 46. One end of the suction tube 46 is connected to one end of the dust collecting unit 38, and the other end 46A of the suction tube 46 is open. The other end 46A of the suction pipe 46 is connected to an exhaust hose (not shown) having one end opened to the outside so that dust passing through the suction pipe 46 can be discharged to the outside. The suction fan 48 is driven when the discharge passage 42 is formed by the dust receiving portion 36 and the dust collection portion 38, and sucks the dust in the discharge passage 42.
　次に、エアフィルタ１８に付着した塵埃を清掃する動作の一例について説明する。エアフィルタ１８に付着した塵埃を清掃する動作中は、塵埃受け部３６は上向き姿勢（図４参照）である。なお、エアフィルタ１８の清掃動作は、図示しない制御部の制御の下で行われる。 Next, an example of an operation for cleaning dust adhering to the air filter 18 will be described. During the operation of cleaning the dust adhering to the air filter 18, the dust receiving portion 36 is in the upward posture (see FIG. 4). The cleaning operation of the air filter 18 is performed under the control of a control unit (not shown).
　図２の状態からギヤ２６が正方向（図２では反時計回り）に回転されると、エアフィルタ１８が第１保持空間２０Ａから第２保持空間２０Ｂへ搬送される。エアフィルタ１８の先端部がブラシ保持部３４とシャフト２４との間を通過するとき、ブラシ保持部３４が正方向（図２では時計回り）に回転して、ブラシ３０の先端部がエアフィルタ１８の先端部と網部分とに跨るように接触する。 When the gear 26 is rotated in the forward direction (counterclockwise in FIG. 2) from the state of FIG. 2, the air filter 18 is conveyed from the first holding space 20A to the second holding space 20B. When the tip of the air filter 18 passes between the brush holder 34 and the shaft 24, the brush holder 34 rotates in the forward direction (clockwise in FIG. 2), and the tip of the brush 30 moves to the air filter 18. It contacts so that the front-end | tip part and net | network part may be straddled.
　ギヤ２６が更に正方向に回転されると、エアフィルタ１８が更に第２保持空間２０Ｂへと搬送される。この搬送の間、ブラシ保持部３４は、ブラシ３０をエアフィルタ１８と接触する位置で固定する。これにより、エアフィルタ１８に付着した塵埃は、定位置で固定されるブラシ３０で堰き止められ、ブラシ３０のエアフィルタ１８の搬送方向の上流側に溜められる。このとき、ブラシ３０に溜められた塵埃とエアフィルタ１８に付着した塵埃とが絡み合って紙縒のように纏まる。これにより、エアフィルタ１８に付着した塵埃の除去効率が向上される。ブラシ３０に付着した塵埃の一部は、隙間Ｓ１を通じて塵埃回収部３８内に掻き落とされる。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一層向上される。 When the gear 26 is further rotated in the forward direction, the air filter 18 is further conveyed to the second holding space 20B. During this conveyance, the brush holding unit 34 fixes the brush 30 at a position where it contacts the air filter 18. Thereby, the dust adhering to the air filter 18 is blocked by the brush 30 fixed at a fixed position, and is accumulated on the upstream side of the air filter 18 in the conveying direction of the brush 30. At this time, the dust accumulated on the brush 30 and the dust adhering to the air filter 18 are entangled and gathered like a paper basket. Thereby, the removal efficiency of the dust adhering to the air filter 18 is improved. Part of the dust adhering to the brush 30 is scraped off into the dust collecting part 38 through the gap S1. In order to make the pressing force of the brush 30 against the air filter 18 constant, for example, the brush 30 may be provided with an elastic body such as a damper. Thereby, the removal efficiency of the dust adhering to the air filter 18 is further improved.
　ギヤ２６が更に正方向に回転され、エアフィルタ１８が第２保持空間２０Ｂに到達すると、ギヤ２６の正方向の回転が停止される。このとき、ブラシ３０の先端部の少なくとも一部は、エアフィルタ１８の清掃領域外にあるエアフィルタ１８の後端部（枠体部分）に接触した状態にある。 When the gear 26 is further rotated in the forward direction and the air filter 18 reaches the second holding space 20B, the forward rotation of the gear 26 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 portion) of the air filter 18 outside the cleaning region of the air filter 18.
　その後、ブラシ保持部３４が逆方向（図２では反時計回り）に回転され、ブラシ３０がブレード３２に接触する位置で揺動される。これにより、ブラシ３０に付着した塵埃の残部が、隙間Ｓ１を通じて塵埃回収部３８内と、塵埃受け部３６に受けられる。なお、このとき、ブラシ３０だけでなく、ブレード３２も揺動させてもよい。これにより、ブラシ３０に付着した塵埃の除去効率を向上させることができる。 Thereafter, the brush holding portion 34 is rotated in the reverse direction (counterclockwise in FIG. 2), and the brush 30 is oscillated at a position where it contacts the blade 32. As a result, the remaining dust adhering to the brush 30 is received in the dust collecting part 38 and the dust receiving part 36 through the gap S1. At this time, not only the brush 30 but also the blade 32 may be swung. Thereby, the removal efficiency of the dust adhering to the brush 30 can be improved.
　ブレード３２によるブラシ３０に付着した塵埃の除去が終了すると、ブラシ保持部３４が逆方向に回転され、ブラシ３０がエアフィルタ１８と接触する位置に復帰する。その後、ギヤ２６が逆方向に回転され、エアフィルタ１８の復路の搬送が開始される。 When the removal of dust attached to the brush 30 by the blade 32 is completed, the brush holding portion 34 is rotated in the reverse direction, and the brush 30 returns to a position where it contacts the air filter 18. Thereafter, the gear 26 is rotated in the reverse direction, and conveyance of the return path of the air filter 18 is started.
　エアフィルタ１８の復路の搬送の間、ブラシ保持部３４は、ブラシ３０をエアフィルタ１８と接触する位置で固定する。これにより、エアフィルタ１８に付着した塵埃は、定位置で固定されるブラシ３０で堰き止められ、ブラシ３０のエアフィルタ１８の搬送方向の上流側に溜められる。ブラシ３０に付着した塵埃の一部は、塵埃受け部３６に受けられる。 During the return path of the air filter 18, the brush holding unit 34 fixes the brush 30 at a position where it contacts the air filter 18. Thereby, the dust adhering to the air filter 18 is blocked by the brush 30 fixed at a fixed position, and is accumulated on the upstream side of the air filter 18 in the conveying direction of the brush 30. Part of the dust adhering to the brush 30 is received by the dust receiver 36.
　エアフィルタ１８の復路の搬送が終了すると、ギヤ２６の逆方向の回転が停止される。その後、ブラシ保持部３４が逆方向（図２では反時計回り）に回転され、ブラシ３０がブレード３２に接触する位置で揺動される。これにより、ブラシ３０に付着した塵埃の残部が、隙間Ｓ１を通じて塵埃回収部３８内と、塵埃受け部３６に受けられる。なお、このとき、上述したように、ブラシ３０だけでなく、ブレード３２も揺動させてもよい。 When the conveyance of the air filter 18 in the return path is completed, the reverse rotation of the gear 26 is stopped. Thereafter, the brush holding portion 34 is rotated in the reverse direction (counterclockwise in FIG. 2), and the brush 30 is oscillated at a position where it contacts the blade 32. As a result, the remaining dust adhering to the brush 30 is received in the dust collecting part 38 and the dust receiving part 36 through the gap S1. At this time, as described above, not only the brush 30 but also the blade 32 may be swung.
　ブレード３２によるブラシ３０に付着した塵埃の除去が終了すると、エアフィルタ１８の清掃動作が完了する。 When the removal of dust attached to the brush 30 by the blade 32 is completed, the cleaning operation of the air filter 18 is completed.
　次に、塵埃受け部３６及び塵埃回収部３８内の塵埃の排出動作について説明する。なお、この塵埃の排出動作を図１５の動作フローチャートに示す。また、制御は図示しない制御部の下で行われる。 Next, the dust discharging operation in the dust receiving part 36 and the dust collecting part 38 will be described. The dust discharge operation is shown in the operation flowchart of FIG. Control is performed under a control unit (not shown).
　掃除運転において、エアフィルタ１８の往路又は復路の搬送が終了すると、エアフィルタ１８の掃除動作が終了し（図１５のステップＳ１０１）、塵埃排出の動作に移行する。塵埃排出動作は、塵埃受け部３６の回転時に障害となるブラシ３０部を邪魔にならない逃がし位置へ移動（ステップＳ１０２）させた後、回転装置４０を駆動させて、塵埃受け部３６を上向き姿勢（図４参照）から下向き姿勢（図５参照）に回転させる。これにより、塵埃受け部３６に受けられた塵埃が塵埃回収部３８内に回収されるとともに、塵埃受け部３６と塵埃回収部３８とで筒状の排出通路４２が形成される。 In the cleaning operation, when the forward or backward conveyance of the air filter 18 is finished, the cleaning operation of the air filter 18 is finished (step S101 in FIG. 15), and the operation proceeds to the dust discharging operation. In the dust discharging operation, the brush 30 that becomes an obstacle during rotation of the dust receiving portion 36 is moved to an escape position that does not obstruct (step S102), and then the rotating device 40 is driven to move the dust receiving portion 36 upward ( 4) to a downward posture (see FIG. 5). Thereby, the dust received by the dust receiving part 36 is recovered in the dust collecting part 38, and a cylindrical discharge passage 42 is formed by the dust receiving part 36 and the dust collecting part 38.
　排出装置の運転（ステップＳ１０３）である吸引装置４４の吸引ファン４８の駆動が既に行われているため、吸引管４６内に吸引力となる気流が発生する。この気流により、排出通路４２内の塵埃が吸引管４６を通じて室外に排出される。 Since the suction fan 48 of the suction device 44, which is the operation of the discharge device (step S103), has already been driven, an air flow serving as a suction force is generated in the suction pipe 46. Due to this air flow, dust in the discharge passage 42 is discharged to the outside through the suction pipe 46.
　この吸引装置４４による排気動作において、塵埃受け部３６の上向き姿勢と下向き姿勢の回転を数回（例えば３回）繰り返す（ステップＳ１０４、ステップＳ１０５、ステップＳ１０６）制御を行い、ブラシ３０は一旦メンテナンス位置に移動し（ステップＳ１０７）、再度、ブラシ３０はシャフト２４の近傍位置へリセットされる（ステップＳ１０８）。そして排出装置である吸引装置４４が停止し（ステップＳ１０９）、塵埃受け部３６及び塵埃回収部３８内の塵埃の排出動作が終了する（ステップＳ１１０）。 In the exhaust operation by the suction device 44, the upward and downward rotation of the dust receiving portion 36 is controlled several times (for example, three times) (step S104, step S105, step S106), and the brush 30 is temporarily set in the maintenance position. (Step S107), the brush 30 is reset again to the position near the shaft 24 (step S108). Then, the suction device 44, which is a discharge device, is stopped (step S109), and the discharge operation of the dust in the dust receiving portion 36 and the dust collecting portion 38 is ended (step S110).
　本実施の形態に係る空気調和機によれば、塵埃受け部３６と塵埃回収部３８とで筒状の排出通路４２を形成し、この排出通路４２に吸引力となる気流を発生させることで塵埃を排出するようにしている。この構成により、塵埃回収部３８を本体２から取り外す等して塵埃回収部３８内の塵埃を除去する必要性を無くすことができる。従って、塵埃回収部３８内の塵埃を除去する手間を軽減することができる。 According to the air conditioner according to the present embodiment, the dust receiving portion 36 and the dust collecting portion 38 form a cylindrical discharge passage 42, and the dust passage is generated by generating an air flow as a suction force in the discharge passage 42. Is to be discharged. With this configuration, it is possible to eliminate the necessity of removing the dust in the dust collecting unit 38 by removing the dust collecting unit 38 from the main body 2 or the like. Therefore, the trouble of removing the dust in the dust collection part 38 can be reduced.
　また、本実施の形態に係る空気調和機によれば、塵埃受け部３６が上向き姿勢であるとき、塵埃受け部３６と塵埃回収部３８との間に隙間Ｓ１が設けられている。この構成によれば、エアフィルタ１８から除去された塵埃の一部を、隙間Ｓ１を通じて塵埃回収部３８に直接的に回収することができる。これにより、エアフィルタ１８から除去された塵埃の全部を塵埃受け部３６が受ける必要性を無くすことができる。 Further, according to the air conditioner according to the present embodiment, when the dust receiving part 36 is in the upward posture, the gap S1 is provided between the dust receiving part 36 and the dust collecting part 38. According to this configuration, a part of the dust removed from the air filter 18 can be directly collected in the dust collecting unit 38 through the gap S1. Thereby, it is possible to eliminate the necessity for the dust receiving part 36 to receive all of the dust removed from the air filter 18.
　また、本実施の形態に係る空気調和機によれば、隙間Ｓ１は、エアフィルタ１８とブラシ３０とが接触する領域の略鉛直下方に設けられている。特に、隙間Ｓ１は、エアフィルタ１８の往路の搬送時に、ブラシ３０のエアフィルタ１８の搬送方向の上流側に設けられていることが好ましい。この構成によれば、隙間Ｓ１を通じて塵埃回収部３８に直接的に回収される塵埃の量を増加させることができる。 Moreover, according to the air conditioner according to the present embodiment, the gap S1 is provided substantially vertically below the region where the air filter 18 and the brush 30 are in contact with each other. In particular, the gap S <b> 1 is preferably provided on the upstream side of the air filter 18 in the conveyance direction of the air filter 18 during the conveyance of the air filter 18 in the forward path. According to this configuration, it is possible to increase the amount of dust collected directly by the dust collection unit 38 through the gap S1.
　また、本実施の形態に係る空気調和機によれば、吸引装置４４が気流により排出通路４２内の塵埃を排出する際、ブレード３２が排出通路４２内に位置するので、ブレード３２に付着した塵埃もこの気流により除去することが可能になる。 Further, according to the air conditioner according to the present embodiment, when the suction device 44 discharges the dust in the discharge passage 42 by the air current, the blade 32 is located in the discharge passage 42, so that the dust adhered to the blade 32 Can also be removed by this air flow.
　また、本実施の形態に係る空気調和機によれば、排出通路４２の他端部が開口部４２Ａを有するので（図３参照）、排出通路４２の略全長にわたって気流を生じさせることができ、排出通路４２内の塵埃の除去効率を向上させることができる。 Further, according to the air conditioner according to the present embodiment, since the other end of the discharge passage 42 has the opening 42A (see FIG. 3), an air flow can be generated over the substantially entire length of the discharge passage 42, The dust removal efficiency in the discharge passage 42 can be improved.
　なお、排出通路４２の他端部の開口部４２Ａを常時開放したままにすると、台風などの強い風が吸引装置４４側から排出通路４２に流入し、排出通路４２を逆流して開口部４２Ａから排出されることが起こり得る。このとき、排出通路４２内に塵埃が存在すると、その塵埃が開口部４２Ａから排出されることが起こり得る。そうすると、開口部４２Ａは、通常室内に位置するので、塵埃が室内に放出されることになる。このため、図７及び図８に示すように、塵埃受け部３６と一体的に回転するように取り付けられ、塵埃受け部３６が下向き姿勢にあるときに開口部４２Ａを開放し（図７参照）、塵埃受け部３６が上向き姿勢にあるときに開口部４２Ａを閉塞する（図８参照）開閉弁５０を備えることが好ましい。この構成によれば、塵埃受け部３６が回転する力を利用して開口部４２Ａを開閉することができ、室内に塵埃が放出されることを抑えることができる。 If the opening 42A at the other end of the discharge passage 42 is kept open at all times, a strong wind such as a typhoon flows into the discharge passage 42 from the suction device 44 side, and flows backward through the discharge passage 42 from the opening 42A. It can happen to be discharged. At this time, if dust is present in the discharge passage 42, the dust may be discharged from the opening 42A. Then, since the opening 42A is normally located in the room, dust is discharged into the room. For this reason, as shown in FIGS. 7 and 8, it is attached so as to rotate integrally with the dust receiving portion 36, and the opening 42A is opened when the dust receiving portion 36 is in the downward posture (see FIG. 7). The opening / closing valve 50 is preferably provided to close the opening 42A (see FIG. 8) when the dust receiving portion 36 is in the upward posture. According to this configuration, the opening 42 </ b> A can be opened and closed using the force of rotating the dust receiving portion 36, and the dust can be prevented from being released into the room.
　なお、排出通路４２の開口部４２Ａは、塵埃回収部３８に設ける必要はない。例えば、排出通路４２の開口部４２Ａは、塵埃受け部３６に設けてもよい。この場合、開口部４２Ａを上向きに設けることで、強い風が吸引装置４４側から回転装置４０側へと流れても、塵埃が重力の影響を受けて開口部４２Ａから排出され難くなる。従って、開閉弁５０を設ける必要性を無くすことができる。 Note that the opening 42 </ b> A of the discharge passage 42 does not need to be provided in the dust collection unit 38. For example, the opening 42 </ b> A of the discharge passage 42 may be provided in the dust receiver 36. In this case, by providing the opening 42A upward, even if strong wind flows from the suction device 44 side to the rotating device 40 side, dust is hardly discharged from the opening 42A due to the influence of gravity. Therefore, it is possible to eliminate the necessity of providing the on-off valve 50.
　また、通常、吸引装置４４の吸引力は、吸引装置４４から離れるほど小さくなる。このため、排出通路４２は、吸引装置４４から離れるに従い開口面積が小さくなるように構成されることが好ましい。図９は塵埃回収部３８に関連する部品の側面図であり、図１０は図９の１０－１０断面図であり、図１１は図９の１１－１１断面図である。図９～図１１に示すように、吸引装置４４から離れるに従い排出通路４２の開口面積が小さくなるように構成することで、吸引装置４４から離れた位置の吸引力を向上させることができる。これにより、排出通路４２内の吸引力をより均一にすることができる。 Also, normally, the suction force of the suction device 44 decreases as the distance from the suction device 44 increases. For this reason, it is preferable that the discharge passage 42 is configured such that the opening area decreases as the distance from the suction device 44 increases. 9 is a side view of parts related to the dust collecting unit 38, FIG. 10 is a sectional view taken along the line 10-10 in FIG. 9, and FIG. 11 is a sectional view taken along the line 11-11 in FIG. As shown in FIGS. 9 to 11, the opening area of the discharge passage 42 decreases as the distance from the suction device 44 increases, so that the suction force at a position away from the suction device 44 can be improved. Thereby, the suction force in the discharge passage 42 can be made more uniform.
　また、排出通路４２の底部は、図９に示すように、吸引装置４４に近づくに従い下方に傾斜していることが好ましい。この構成によれば、排出通路４２内の塵埃を、重力を利用して吸引装置４４側へ誘導することができ、排出通路４２内の塵埃の除去効率を向上させることができる。 Further, as shown in FIG. 9, the bottom of the discharge passage 42 is preferably inclined downward as it approaches the suction device 44. According to this configuration, the dust in the discharge passage 42 can be guided to the suction device 44 side using gravity, and the dust removal efficiency in the discharge passage 42 can be improved.
　また、塵埃回収部３８の長手方向の中間部には、塵埃受け部３６を下方から支持する支持部材５２が設けられることが好ましい。図１２は塵埃受け部３６に関連する部品を示す斜視図であり、図１３は図１２の支持部材５２の周辺の構成を示す拡大斜視図であり、図１４は図１２の１４－１４断面図である。図１２～図１４に示すように、塵埃受け部３６を下方から支持する支持部材５２を設けることで、支持部材５２により塵埃受け部３６が撓むことを抑えることができる。また、支持部材５２は、下向き姿勢の塵埃受け部３６の下端部よりも上方に設けられることが好ましい。例えば、塵埃受け部３６の長手方向の中間部に、支持部材５２を受け入れる溝部３６Ｃを設け、支持部材５２を塵埃回収部３８の段部３８Ａに載置するように構成することが好ましい。この構成によれば、排出通路４２の開口面積が支持部材５２により狭くなることを抑えることができる。これにより、排出通路４２内の気流の流れを円滑にして、排出通路４２内の塵埃の除去効率を向上させることができる。なお、塵埃受け部３６は、２つの部材に分割して、この２つの部材を溝部３６Ｃで連結するように構成されてもよい。 Further, it is preferable that a support member 52 for supporting the dust receiving portion 36 from below is provided at an intermediate portion in the longitudinal direction of the dust collecting portion 38. 12 is a perspective view showing components related to the dust receiving portion 36, FIG. 13 is an enlarged perspective view showing a configuration around the support member 52 of FIG. 12, and FIG. 14 is a sectional view taken along line 14-14 of FIG. It is. As shown in FIGS. 12 to 14, by providing the support member 52 that supports the dust receiving portion 36 from below, it is possible to prevent the dust receiving portion 36 from being bent by the support member 52. Moreover, it is preferable that the support member 52 is provided above the lower end portion of the dust receiving portion 36 in the downward posture. For example, it is preferable that a groove portion 36 </ b> C for receiving the support member 52 is provided in an intermediate portion in the longitudinal direction of the dust receiving portion 36, and the support member 52 is placed on the stepped portion 38 </ b> A of the dust collection portion 38. According to this configuration, it is possible to suppress the opening area of the discharge passage 42 from being narrowed by the support member 52. Thereby, the flow of the airflow in the discharge passage 42 can be made smooth, and the dust removal efficiency in the discharge passage 42 can be improved. The dust receiving portion 36 may be configured to be divided into two members and to connect the two members with the groove portion 36C.
　また、ブレード３２が塵埃受け部３６に保持される場合、ブレード３２とブラシ３０とが接触する際に生じる圧力が塵埃受け部３６にかかる。この場合、塵埃受け部３６は長尺部材であるので、塵埃受け部３６が変形することが起こり得る。このため、塵埃受け部３６は、図１４に示すように、回転装置４０により回転される方向に切った断面において凸状に湾曲する湾曲面３６Ｄを有し、ブレード３２は、湾曲面３６Ｄの頂部に設けられることが好ましい。この構成によれば、塵埃受け部３６が平板状である場合よりも、塵埃受け部３６の強度を向上させることができる。 Further, when the blade 32 is held by the dust receiving portion 36, pressure generated when the blade 32 and the brush 30 come into contact is applied to the dust receiving portion 36. In this case, since the dust receiving part 36 is a long member, the dust receiving part 36 may be deformed. For this reason, as shown in FIG. 14, the dust receiving part 36 has a curved surface 36D that curves in a convex shape in a cross section cut in the direction of rotation by the rotating device 40, and the blade 32 is the top of the curved surface 36D. It is preferable to be provided. According to this structure, the intensity | strength of the dust receiving part 36 can be improved rather than the case where the dust receiving part 36 is flat form.
　また、塵埃受け部３６の表面は、油成分を含む塵埃が固着しないように加工されることが好ましい。例えば、塵埃受け部３６の表面に、塵埃が詰まらない程度の間隔を空けて複数の凸状の突起部を設けることが好ましい。この構成によれば、塵埃の除去効率を一層向上させることができる。 Further, the surface of the dust receiving portion 36 is preferably processed so that dust containing an oil component does not adhere. For example, it is preferable to provide a plurality of convex protrusions on the surface of the dust receiving portion 36 with an interval that does not clog the dust. According to this configuration, dust removal efficiency can be further improved.
　また、塵埃受け部３６の表面には、微細な貫通穴が設けられることが好ましい。この構成によれば、ブレード３２の表面に塵埃が固着しても、図５に示すように、排出通路４２内にブレード３２が位置する状態で、排出通路４２内に気流を発生させたとき、この気流が貫通穴を通ることにより塵埃受け部３６の表面から塵埃を除去することができる。 Further, it is preferable that a fine through hole is provided on the surface of the dust receiving portion 36. According to this configuration, even when dust adheres to the surface of the blade 32, when airflow is generated in the discharge passage 42 with the blade 32 positioned in the discharge passage 42 as shown in FIG. Dust can be removed from the surface of the dust receiving portion 36 by the airflow passing through the through hole.
　また、塵埃受け部３６と回転装置４０とは、分離可能に構成されることが好ましい。例えば、塵埃受け部３６と回転装置４０とは、それぞれギヤを備え、それぞれのギヤを噛み合わせることにより回転動力が伝達されるようにしてもよい。これにより、例えば、使用者が塵埃受け部３６及び塵埃回収部３８を本体２から取り外す際に、動力源である回転装置４０まで取り外す必要性を無くすことができる。 Further, it is preferable that the dust receiving portion 36 and the rotating device 40 are configured to be separable. For example, the dust receiver 36 and the rotating device 40 may each include a gear, and the rotational power may be transmitted by meshing each gear. Thereby, for example, when the user removes the dust receiving part 36 and the dust collecting part 38 from the main body 2, it is possible to eliminate the necessity of removing the rotating device 40 that is a power source.
　（第２の実施の形態）
　次に、本発明の第２の実施の形態に係る空気調和機について説明する。図１６は、本実施の形態に係る空気調和機の室内機の断面図である。 (Second Embodiment)
Next, an air conditioner according to a second embodiment of the present invention will be described. FIG. 16 is a cross-sectional view of the indoor unit of the air conditioner according to the present embodiment.
　本実施の形態に係る空気調和機が第１の実施の形態に係る空気調和機と異なる点は、吸引装置４４に代えて、排出装置として排出通路４２内の塵埃を送風により押し出す送風装置６０を備えている点である。 The air conditioner according to the present embodiment is different from the air conditioner according to the first embodiment in that instead of the suction device 44, a blower device 60 that pushes out dust in the discharge passage 42 by blowing air as a discharge device. It is a point that has.
　本実施の形態において、送風装置６０は、ファン８と、ファン８から吹き出される空気が排出通路４２内に送風されるように風向を切り替える風向切替装置６２を備えている。すなわち、本実施の形態においては、送風装置６０の風力源として、空気調和機が通常備えるファン８を共用するようにしている。 In the present embodiment, the blower 60 includes a fan 8 and a wind direction switching device 62 that switches the wind direction so that air blown from the fan 8 is blown into the discharge passage 42. That is, in the present embodiment, the fan 8 that is normally provided in the air conditioner is shared as a wind power source of the blower 60.
　風向切替装置６２は、通風路１６と排出通路４２の一端部とを連通する送風管６４と、送風管６４の開口部６４Ａを開閉する開閉弁６６とを備えている。開閉弁６６は、冷房や暖房などの空調運転中は、送風管６４の開口部６４Ａを閉塞する。このため、ファン８から吹き出される空気は、排出通路４２内には流れない。一方、開閉弁６６は、上述した塵埃受け部３６及び塵埃回収部３８内の塵埃の排出動作時において、通風路１６に形成した開口部６４Ａを開放する。これにより、通風路１６と排出通路４２の一端部とが送風管６４を通じて連通し、ファン８から吹き出される空気は、気流として排出通路４２内に流れる。 The air direction switching device 62 includes a blower pipe 64 that communicates the ventilation path 16 and one end of the discharge passage 42, and an opening / closing valve 66 that opens and closes the opening 64 </ b> A of the blower pipe 64. The on-off valve 66 closes the opening 64 </ b> A of the blower pipe 64 during an air conditioning operation such as cooling or heating. For this reason, the air blown out from the fan 8 does not flow into the discharge passage 42. On the other hand, the opening / closing valve 66 opens the opening 64 </ b> A formed in the ventilation path 16 during the dust discharging operation in the dust receiving part 36 and the dust collecting part 38 described above. Thereby, the ventilation path 16 and the one end part of the discharge passage 42 communicate with each other through the blower pipe 64, and the air blown out from the fan 8 flows into the discharge passage 42 as an air flow.
　なお、図１６では、開閉弁６６を、送風管６４の通風路１６側の端部（開口部６４Ａ）に設けているが、これに加えて、もしくはこれとは別に開閉弁（図示せず）を排出通路４２側の端部に設けてもよい。この場合には、開閉弁（図示せず）を、塵埃受け部３６と一体的に回転するように取り付け、塵埃受け部３６が上向き姿勢にあるときに通風路１６を閉塞し、塵埃受け部３６が下向き姿勢にあるときに通風路１６を開放する開閉弁として構成することもできる。つまり、開閉弁（図示せず）を塵埃受け部３６と一体的に回転するように取り付け、通常時には通風路１６を閉塞し、塵埃の排出動作時にのみ通風路１６を開放する開閉弁としてもよい。 In FIG. 16, the opening / closing valve 66 is provided at the end (opening 64 </ b> A) of the blower pipe 64 on the side of the ventilation path 16, but in addition to or separately from the opening / closing valve (not shown). May be provided at the end on the discharge passage 42 side. In this case, an on-off valve (not shown) is attached so as to rotate integrally with the dust receiving portion 36, and the ventilation path 16 is closed when the dust receiving portion 36 is in the upward posture, so that the dust receiving portion 36 is closed. It can also be configured as an on-off valve that opens the ventilation path 16 when is in a downward posture. In other words, an open / close valve (not shown) may be attached so as to rotate integrally with the dust receiving portion 36, and the air passage 16 may be closed during normal operation, and the air passage 16 may be opened only during the dust discharging operation. .
　本実施の形態において、排出通路４２の他端部は、室外と連通するように設けられている。例えば、排出通路４２の他端部は、排気ホース（図示せず）を介して、室外に開口している。このため、排出通路４２内の塵埃は、排出通路４２内を流れる空気によって押し出され、排出通路４２の他端部から室外へ排出される。なお、この排出動作時において、吹出口１０は、上下風向変更羽根１２により閉塞され、ファン８から吹き出される空気は、概ね送風管６４へ流れるようにする。 In the present embodiment, the other end of the discharge passage 42 is provided so as to communicate with the outdoors. For example, the other end of the discharge passage 42 is opened to the outside via an exhaust hose (not shown). For this reason, the dust in the discharge passage 42 is pushed out by the air flowing in the discharge passage 42 and discharged from the other end of the discharge passage 42 to the outside of the room. During the discharge operation, the air outlet 10 is closed by the up / down air direction changing blades 12 so that the air blown out from the fan 8 flows to the blower pipe 64 in general.
　本実施の形態に係る空気調和機によれば、送風装置６０の風力源としてファン８を利用するので、排出通路４２内の塵埃を送風するために別途風力源を設ける必要性を無くすことができる。従って、コストダウンを図ることが可能になる。また、省スペース化が可能となるので、そのスペースを有効に利用することで、例えば熱交換器を大きくしたり、ファンの長さを長くするなどして性能向上を実現したり、付加機能部品を備えるなどして機能向上を実現したりすることもできる。なお、送風装置６０の風力源としてファン８とは別の風力源を用いてもよい。 According to the air conditioner according to the present embodiment, since the fan 8 is used as the wind power source of the blower 60, it is possible to eliminate the necessity of providing a separate wind power source for blowing dust in the discharge passage 42. . Therefore, the cost can be reduced. In addition, since space can be saved, the space can be effectively used to improve performance by, for example, increasing the size of the heat exchanger or increasing the length of the fan. It is also possible to achieve functional improvements by providing Note that a wind source other than the fan 8 may be used as the wind source of the blower 60.
　本発明の空気調和機は、室内機に内蔵されたエアフィルタに付着した塵埃を清掃するフィルタ清掃機能を備える空気調和機であって、エアフィルタに付着した塵埃を除去するブラシと、ブラシに付着した塵埃を掻き落とすブレードと、ブレードに掻き落とされた塵埃を受ける塵埃受け部と、塵埃受け部の下方に配置された塵埃回収部を備える。また、塵埃受け部が受けた塵埃が塵埃回収部に回収されるように、塵埃受け部を上向き姿勢から下向き姿勢に回転させる回転装置と、塵埃回収部に回収された塵埃を気流により排出する排出装置を備える。さらに、塵埃受け部が下向き姿勢であるとき、塵埃受け部と塵埃回収部とで筒状の排出通路が構成され、排出装置は、排出通路内に気流を発生させることで塵埃を排出するように構成している。 The air conditioner of the present invention is an air conditioner having a filter cleaning function for cleaning dust adhering to an air filter built in an indoor unit, the brush for removing dust adhering to the air filter, and the brush adhering to the brush A blade that scrapes off the dust, a dust receiving portion that receives the dust scraped off by the blade, and a dust collecting portion that is disposed below the dust receiving portion. In addition, a rotating device that rotates the dust receiving portion from an upward position to a downward posture so that the dust received by the dust receiving portion is collected by the dust collecting portion, and a discharge that discharges the dust collected by the dust collecting portion by an air flow Equipment. Further, when the dust receiving portion is in the downward posture, the dust receiving portion and the dust collecting portion form a cylindrical discharge passage, and the discharge device discharges dust by generating an air flow in the discharge passage. It is composed.
　この構成によれば、塵埃受け部と塵埃回収部とで筒状の排出通路を構成し、その排出通路に気流を発生させることで塵埃を排出するようにしているので、塵埃回収部を空気調和機本体から取り外す等して塵埃回収部内の塵埃を除去する必要性を無くすことができる。従って、塵埃回収部内の塵埃を除去する手間を軽減することができる。 According to this configuration, the dust receiving portion and the dust collecting portion constitute a cylindrical discharge passage, and dust is discharged by generating an air flow in the discharge passage. It is possible to eliminate the necessity of removing dust from the dust collecting unit by removing it from the machine body. Therefore, the trouble of removing the dust in the dust collecting part can be reduced.
　なお、排出装置は、排出通路内の塵埃を吸引する吸引装置であってもよい。 Note that the discharge device may be a suction device that sucks dust in the discharge passage.
　なお、通常、吸引装置の吸引力は、吸引装置から離れるほど小さくなる。このため、排出通路は、吸引装置から離れるに従い開口面積が小さくなるように構成してもよい。この構成によれば、吸引装置から離れた位置の吸引力を向上させることができ、排出通路内の吸引力をより均一にすることができる。 Note that the suction force of the suction device usually decreases as the distance from the suction device increases. For this reason, you may comprise a discharge channel so that an opening area may become small as it leaves | separates from a suction device. According to this configuration, the suction force at a position away from the suction device can be improved, and the suction force in the discharge passage can be made more uniform.
　また、排出通路の底部は、吸引装置に近づくに従い下方に傾斜させてもよい。この構成によれば、排出通路内の塵埃を、重力を利用して吸引装置側へ誘導することができ、排出通路内の塵埃の除去効率を向上させることができる。 Also, the bottom of the discharge passage may be inclined downward as it approaches the suction device. According to this configuration, the dust in the discharge passage can be guided to the suction device side using gravity, and the removal efficiency of the dust in the discharge passage can be improved.
　また、排出装置は、排出通路内の塵埃を送風により押し出す送風装置であってもよい。 Further, the discharge device may be a blower that pushes out dust in the discharge passage by blowing air.
　この場合、空気調和機は、熱交換器と、熱交換器により熱交換された空気を室内に吹き出すためのファンとを備え、送風装置は、ファンから吹き出される空気が排出通路内に送風されるように風向を切り替える風向切替装置を備えてもよい。この構成によれば、送風装置の風力源として、空気調和機が通常備えるファンを利用することができ、排出通路内の塵埃を送風するために別途風力源を設ける必要性を無くすことができる。従って、コストダウンを図ることが可能になる。また、省スペース化が可能となるので、そのスペースを有効に利用することで、性能向上や機能向上を実現することもできる。 In this case, the air conditioner includes a heat exchanger and a fan for blowing the air heat-exchanged by the heat exchanger into the room, and the blower blows air blown from the fan into the discharge passage. A wind direction switching device that switches the wind direction may be provided. According to this structure, the fan with which an air conditioner is normally equipped can be utilized as a wind power source of an air blower, and the necessity to provide a separate wind power source in order to blow the dust in a discharge channel can be eliminated. Therefore, the cost can be reduced. In addition, since space can be saved, it is possible to improve performance and functions by effectively using the space.
　また、ブレードは、塵埃受け部に保持され、塵埃受け部が下向き姿勢であるとき、排出通路内に位置するように設けてもよい。この構成によれば、排出装置が気流により排出通路内の塵埃を排出する際、ブレードが排出通路内に位置することになるので、ブレードに付着した塵埃も気流により除去することが可能になる。 Further, the blade may be provided so as to be held in the dust receiving portion and positioned in the discharge passage when the dust receiving portion is in a downward posture. According to this configuration, when the discharge device discharges dust in the discharge passage by the airflow, the blade is positioned in the discharge passage, so that dust attached to the blade can also be removed by the airflow.
　また、塵埃回収部は、排出通路内に位置するブレードから下方に離れるように突出する突出部を有してもよい。この構成によれば、ブレードと塵埃回収部の底部との間隔を拡大することができ、ブレードと塵埃回収部の底部との間に塵埃が詰まることを抑えることができる。 Further, the dust collecting part may have a protruding part that protrudes downward from the blade located in the discharge passage. According to this configuration, it is possible to increase the distance between the blade and the bottom of the dust collection unit, and it is possible to suppress clogging of dust between the blade and the bottom of the dust collection unit.
　なお、ブレードが塵埃受け部に保持される場合、ブレードとブラシとが接触する際に生じる圧力が塵埃受け部にかかる。この場合、塵埃受け部は通常長尺部材であるので、塵埃受け部が変形することが起こり得る。このため、塵埃受け部は、回転装置により回転される方向に切った断面において凸状に湾曲する湾曲面を有し、ブレードは、湾曲面の頂部に設ける構成としてもよい。この構成によれば、塵埃受け部が平板状である場合よりも、塵埃受け部の強度を向上させることができる。 When the blade is held by the dust receiving portion, pressure generated when the blade and the brush come into contact is applied to the dust receiving portion. In this case, since the dust receiving part is usually a long member, the dust receiving part may be deformed. For this reason, the dust receiving portion may have a curved surface that curves in a convex shape in a cross section cut in the direction rotated by the rotating device, and the blade may be provided on the top of the curved surface. According to this configuration, the strength of the dust receiving portion can be improved as compared with the case where the dust receiving portion is flat.
　また、排出通路の一端部は、排出装置に接続され、排出通路の他端部は、開口部を有してもよい。この構成によれば、排出通路の略全長にわたって気流を生じさせることができ、排出通路内の塵埃の除去効率を向上させることができる。 Also, one end of the discharge passage may be connected to the discharge device, and the other end of the discharge passage may have an opening. According to this configuration, an air flow can be generated over substantially the entire length of the discharge passage, and the dust removal efficiency in the discharge passage can be improved.
　なお、排出通路の他端部の開口部を常時開放したままにすると、台風などの強い風が排出装置側から排出通路に流入し、排出通路を逆流して開口部から排出されることが起こり得る。このとき、排出通路内に塵埃が存在すると、その塵埃が開口部から排出されることが起こり得る。通常、開口部は、室内に位置するので、塵埃が室内に放出されることになる。このため、塵埃受け部と一体的に回転するように取り付けられ、塵埃受け部が上向き姿勢にあるときに排出通路の開口部を開放し、塵埃受け部が下向き姿勢にあるときに排出通路の開口部を閉塞する開閉弁を更に備えてもよい。この構成によれば、塵埃受け部が回転する力を利用して開口部を開閉することができ、室内に塵埃が放出されることを抑えることができる。 If the opening at the other end of the discharge passage is kept open at all times, strong winds such as typhoons may flow into the discharge passage from the discharge device side and flow back through the discharge passage and be discharged from the opening. obtain. At this time, if dust is present in the discharge passage, the dust may be discharged from the opening. Usually, since the opening is located in the room, dust is discharged into the room. For this reason, it is attached so as to rotate integrally with the dust receiver, and the opening of the discharge passage is opened when the dust receiver is in the upward posture, and the opening of the discharge passage is opened when the dust receiver is in the downward posture. You may further provide the on-off valve which obstruct | occludes a part. According to this configuration, the opening can be opened and closed using the force of rotating the dust receiving portion, and the dust can be prevented from being released into the room.
　また、塵埃受け部が上向き姿勢であるとき、塵埃受け部と塵埃回収部との間に、ブラシによってエアフィルタから除去された塵埃の一部を通過させる隙間を設けてもよい。この構成によれば、エアフィルタから除去された塵埃の一部を、隙間を通じて塵埃回収部に直接的に回収することができる。これにより、エアフィルタから除去された塵埃の全部を塵埃受け部が受ける必要性を無くすことができる。 Further, when the dust receiving part is in the upward posture, a gap for allowing a part of the dust removed from the air filter by the brush to pass therethrough may be provided between the dust receiving part and the dust collecting part. According to this configuration, a part of the dust removed from the air filter can be directly collected in the dust collecting unit through the gap. Thereby, it is possible to eliminate the necessity for the dust receiving portion to receive all of the dust removed from the air filter.
　なお、隙間は、エアフィルタとブラシとが接触する領域の略鉛直下方に設けてもよい。この構成によれば、隙間を通じて塵埃回収部に直接的に回収される塵埃の量を増加させることができる。 It should be noted that the gap may be provided substantially vertically below the area where the air filter and the brush contact. According to this configuration, it is possible to increase the amount of dust that is directly collected by the dust collecting unit through the gap.
　また、塵埃回収部の長手方向の中間部には、塵埃受け部を下方から支持する支持部材が設けられ、下向き姿勢の塵埃受け部の下端部よりも上方に設けてもよい。この構成によれば、支持部材により塵埃受け部が撓むことを抑えることができるとともに、排出通路の開口面積が支持部材により狭くなることを抑えることができる。これにより、排出通路内の気流の流れを円滑にして、排出通路内の塵埃の除去効率を向上させることができる。 Further, a support member for supporting the dust receiving portion from below is provided at the middle portion in the longitudinal direction of the dust collecting portion, and may be provided above the lower end portion of the dust receiving portion in the downward posture. According to this configuration, it is possible to suppress the dust receiving portion from being bent by the support member, and it is possible to suppress the opening area of the discharge passage from being narrowed by the support member. Thereby, the flow of the airflow in the discharge passage can be made smooth, and the dust removal efficiency in the discharge passage can be improved.
　また、塵埃の排出は、塵埃受け部が上向き姿勢にある状態で排気装置を駆動させてから塵埃受け部を下向き姿勢に回転させてもよい。この順序での制御とすることで、塵埃回収部の塵埃は、塵埃受け部で排気通路が完全に形成される前から徐々に排気側に移動し始めるため、塵埃の排気が円滑になり、排気通路内の塵埃の除去効率を向上させることができる。 Further, the dust may be discharged by driving the exhaust device in a state where the dust receiving portion is in the upward posture and then rotating the dust receiving portion in the downward posture. By controlling in this order, the dust in the dust collecting part starts to move gradually to the exhaust side before the exhaust passage is completely formed in the dust receiving part. The removal efficiency of dust in the passage can be improved.
　また、塵埃受け部の上向き姿勢と下向き姿勢の回転を数回繰り返し動作させてもよい。このことにより、排気通路や塵埃回収部に静電気などの力で付着した細かな塵埃や、ブレードに絡まった塵埃なども脱離させることが可能となり、排気通路内の塵埃の除去効率を向上させることができる。 Also, the upward and downward posture rotation of the dust receiving portion may be repeated several times. This makes it possible to remove fine dust adhered to the exhaust passage and dust collecting part by static electricity, and dust entangled with the blade, and improve the efficiency of removing dust in the exhaust passage. Can do.
　以上のように、本発明にかかる空気調和機は、塵埃回収部内の塵埃を除去する手間を軽減することができるので、一般家庭で使用される空気調和機を含む様々な空気調和機として有用である。 As described above, since the air conditioner according to the present invention can reduce the trouble of removing dust in the dust collection unit, it is useful as various air conditioners including an air conditioner used in a general household. is there.
