The air supply air passage 30 is an air passage that lowers the outdoor air from the outdoor air supply port 21, takes it into the ceiling 20, and blows it indoors from the indoor air supply port 24. The exhaust air passage 40 is an air passage that lowers the indoor air from the indoor exhaust port 23, takes it into the ceiling 20, and exhausts it to the outside from the outdoor exhaust port 22.
　この実施の形態の空気調和機は、集塵装置本体１と熱交換換気装置１０とを備えている。集塵装置本体１と熱交換換気装置１０とは、給気風路３０の上流側から、この順序で配置されている。また、排気風路４０には、熱交換換気装置１０が配置されている。給気風路３０において、室外給気口２１と室内給気口２４とは、集塵装置本体１と熱交換換気装置１０とを介して給気ダクト３１で接続されている。また、排気風路４０において、室内排気口２３と室外排気口２２とは、熱交換換気装置１０を介して排気ダクト４１で接続されている。 The air conditioner of this embodiment includes a dust collector main body 1 and a heat exchange ventilation device 10. The dust collector main body 1 and the heat exchange ventilation device 10 are arranged in this order from the upstream side of the air supply air passage 30. Further, a heat exchange ventilation device 10 is arranged in the exhaust air passage 40. In the air supply air passage 30, the outdoor air supply port 21 and the indoor air supply port 24 are connected by an air supply duct 31 via a dust collector main body 1 and a heat exchange ventilation device 10. Further, in the exhaust air passage 40, the indoor exhaust port 23 and the outdoor exhaust port 22 are connected by an exhaust duct 41 via a heat exchange ventilation device 10.
　熱交換換気装置１０は、換気機能と空調補助機能とを有する換気装置である。換気機能とは、室外空気を室内へ給気し、室内空気を室外に排気する機能である。この換気機能を実現する構成として、熱交換換気装置１０は、給気風路３０において室外から室内に向けて空気を送風するファン（図示せず）と、排気風路４０において室内から室外に向けて空気を送風するファン（図示せず）とを有している。 The heat exchange ventilation device 10 is a ventilation device having a ventilation function and an air conditioning auxiliary function. The ventilation function is a function of supplying outdoor air to the room and exhausting the indoor air to the outside. As a configuration for realizing this ventilation function, the heat exchange ventilation device 10 includes a fan (not shown) that blows air from the outside to the inside of the air supply air passage 30 and an exhaust air passage 40 from the inside to the outside. It has a fan (not shown) that blows air.
　また、空調補助機能とは、排気する室内空気から熱を回収し、回収した熱を給気する空気へ与えることで、エアコン等の室内温度を調整する機器の空調動作を補助する機能である。空調補助機能は、機器におけるエネルギー負担を軽減する機能であることから省エネルギー機能ともいえる。この空調補助機能を実現する構成として、熱交換換気装置１０は排気風路４０を通過する空気と給気風路３０を通過する空気との間で熱交換する熱交換器（図示せず）を備えている。 The air conditioning assist function is a function that assists the air conditioning operation of equipment that adjusts the room temperature, such as an air conditioner, by recovering heat from the exhausted indoor air and giving the recovered heat to the air to be supplied. The air conditioning auxiliary function can be said to be an energy saving function because it is a function that reduces the energy burden on the equipment. As a configuration for realizing this air conditioning assist function, the heat exchange ventilation device 10 includes a heat exchanger (not shown) that exchanges heat between the air passing through the exhaust air passage 40 and the air passing through the air supply air passage 30. ing.
　集塵装置本体１は、室外給気口２１から下がり天井２０内に流入した室外空気中の塵埃を捕集する装置である。集塵装置本体１の詳細については改めて説明する。集塵装置本体１の上流側と下流側にはそれぞれ、空気の塵埃濃度を検出する第１のパーティクルセンサ１１ａ及び第２のパーティクルセンサ１１ｂが設けられている。上流側の第１のパーティクルセンサ１１ａは、室外空気中の塵埃濃度を検出する。下流側の第２のパーティクルセンサ１１ｂは、塵埃除去後の空気中の塵埃濃度を検出する。第１のパーティクルセンサ１１ａ及び第２のパーティクルセンサ１１ｂのそれぞれの検出信号は後述の連携制御部２５に出力される。 The dust collector main body 1 is a device that collects dust in the outdoor air that has fallen from the outdoor air supply port 21 and has flowed into the ceiling 20. The details of the dust collector main body 1 will be described again. A first particle sensor 11a and a second particle sensor 11b for detecting the dust concentration of air are provided on the upstream side and the downstream side of the dust collector main body 1, respectively. The first particle sensor 11a on the upstream side detects the dust concentration in the outdoor air. The second particle sensor 11b on the downstream side detects the dust concentration in the air after removing the dust. The detection signals of the first particle sensor 11a and the second particle sensor 11b are output to the cooperation control unit 25 described later.
　空気調和機は、さらに、集塵装置本体１と熱交換換気装置１０との運転を連携させる連携制御部２５を備えている。連携制御部２５は、集塵装置本体１及び熱交換換気装置１０のそれぞれと電気的に接続されている。また、連携制御部２５は、第１のパーティクルセンサ１１ａ及び第２のパーティクルセンサ１１ｂからの検出信号に基づいて集塵装置本体１及び熱交換換気装置１０の運転を制御する。連携制御部２５は、その機能を実現する回路デバイスのようなハードウェアで構成することもできるし、マイコン又はＣＰＵのような演算装置と、その上で実行されるソフトウェアとにより構成することもできる。 The air conditioner further includes a coordinated control unit 25 that links the operation of the dust collector main body 1 and the heat exchange ventilator 10. The cooperative control unit 25 is electrically connected to each of the dust collector main body 1 and the heat exchange ventilation device 10. Further, the cooperative control unit 25 controls the operation of the dust collector main body 1 and the heat exchange ventilation device 10 based on the detection signals from the first particle sensor 11a and the second particle sensor 11b. The cooperative control unit 25 can be configured by hardware such as a circuit device that realizes the function, or can be configured by a computing device such as a microcomputer or a CPU and software executed on the arithmetic unit. ..
　次に、図２を参照しながら集塵装置本体１の構成について説明する。同図に示すように、集塵装置本体１は、筐体１５を備えている。筐体１５の内部には、回転駆動される複数の捕集板２と、複数のブラシ３と、ダストボックス４とが収納されている。筐体１５には、吸入口１３と排出口１４とが形成されている。そして、筐体１５内には、吸入口１３から吸入された空気が排出口１４から排気される風路１６が形成されている。集塵装置本体１は、図１に示すように給気風路３０に設けられている。このため、集塵装置本体１の風路１６には、室外給気口２１から流入した室外空気が通過するようになっている。 Next, the configuration of the dust collector main body 1 will be described with reference to FIG. As shown in the figure, the dust collector main body 1 includes a housing 15. Inside the housing 15, a plurality of collection plates 2 that are rotationally driven, a plurality of brushes 3, and a dust box 4 are housed. The housing 15 is formed with a suction port 13 and a discharge port 14. An air passage 16 is formed in the housing 15 in which the air sucked from the suction port 13 is exhausted from the discharge port 14. The dust collector main body 1 is provided in the air supply air passage 30 as shown in FIG. Therefore, the outdoor air flowing in from the outdoor air supply port 21 passes through the air passage 16 of the dust collector main body 1.
　捕集板２は、負の摩擦帯電傾向を有するＰＰ（Ｐｏｌｙ　Ｐｒｏｐｙｌｅｎｅ）のプラスチック板である。捕集板２は、例えば、厚さ１ｍｍ、直径３００ｍｍの円形状を呈する。複数の捕集板２は、筐体１５における室外空気の通過方向と交差する方向に例えば３ｍｍの間隔を開けて配列されている。複数の捕集板２は、それぞれの捕集板２の中央部を貫通する第１のシャフト８によって結合されて全体が一体化されている。 The collection plate 2 is a PP (Poly Propene) plastic plate having a negative triboelectric tendency. The collection plate 2 has, for example, a circular shape having a thickness of 1 mm and a diameter of 300 mm. The plurality of collection plates 2 are arranged at intervals of, for example, 3 mm in a direction intersecting the passage direction of the outdoor air in the housing 15. The plurality of collection plates 2 are connected by a first shaft 8 penetrating the central portion of each collection plate 2, and the whole is integrated.
　ブラシ３は、捕集板２の表面を摩擦して捕集板２の表面に静電気を帯電させるとともに、捕集板２で捕集した塵埃を払い落とすものである。図３に示すように、ブラシ３は、支持板３ａに不織布３ｂを貼り付けた構成を有する。支持板３ａは、例えば厚さ１ｍｍの長方形状を呈するアルミニウムからなる部材である。不織布３ｂは、正の摩擦帯電傾向を有する例えばＰＡ６（Ｐｏｌｙａｍｉｄｅ６）繊維からなる。 The brush 3 rubs the surface of the collection plate 2 to charge the surface of the collection plate 2 with static electricity, and at the same time, removes the dust collected by the collection plate 2. As shown in FIG. 3, the brush 3 has a structure in which the non-woven fabric 3b is attached to the support plate 3a. The support plate 3a is, for example, a member made of aluminum having a rectangular shape with a thickness of 1 mm. The non-woven fabric 3b is made of, for example, PA6 (Polyamide 6) fibers having a positive triboelectric tendency.
　各支持板３ａには、２つの取付穴３ｃが空けられている。複数のブラシ３は、各取付穴３ｃに第２のシャフト９がそれぞれ挿入されて結合されている。また、結合された複数のブラシ３は、第２のシャフト９により筐体１５に固定されている。そして、各ブラシ３は、不織布３ｂが各捕集板２の表面に接触するように捕集板２同士の間の隙間に差し込まれている。各ブラシ３は全て接地されている。 Each support plate 3a has two mounting holes 3c. A second shaft 9 is inserted into each of the mounting holes 3c to connect the plurality of brushes 3. Further, the plurality of combined brushes 3 are fixed to the housing 15 by the second shaft 9. Then, each brush 3 is inserted into a gap between the collection plates 2 so that the non-woven fabric 3b comes into contact with the surface of each collection plate 2. Each brush 3 is all grounded.
　ブラシ３は、捕集板２の下流側に配置されている。また、ブラシ３は、室外空気の通過方向に沿った姿勢で捕集板２間に配置されている。この例では、ブラシ３は水平姿勢で配置されている。このようにブラシ３を配置することで、筐体１５内を通過する室外空気に対する通風抵抗を低減できる。 The brush 3 is arranged on the downstream side of the collection plate 2. Further, the brush 3 is arranged between the collection plates 2 in a posture along the passing direction of the outdoor air. In this example, the brush 3 is arranged in a horizontal position. By arranging the brush 3 in this way, it is possible to reduce the ventilation resistance to the outdoor air passing through the housing 15.
　筐体１５内において、ブラシ３の鉛直下方には、ダストボックス４が配置されている。ダストボックス４は、凝集体１７を回収するための容器である。凝集体１７は、捕集板２に付着してブラシ３で除去された塵埃等の塊である。 In the housing 15, the dust box 4 is arranged vertically below the brush 3. The dust box 4 is a container for collecting the agglomerates 17. The agglomerate 17 is a mass of dust or the like that adheres to the collection plate 2 and is removed by the brush 3.
　筐体１５内には第１のバッフル材１８及び第２のバッフル材１９がさらに設けられている。第１のバッフル材１８及び第２のバッフル材１９は、捕集板２を挟んで対向するように配置されている。第１のバッフル材１８及び第２のバッフル材１９は、筐体１５内に流入した室外空気が捕集板２を通過するように整流するものである。 A first baffle material 18 and a second baffle material 19 are further provided in the housing 15. The first baffle material 18 and the second baffle material 19 are arranged so as to face each other with the collection plate 2 interposed therebetween. The first baffle material 18 and the second baffle material 19 rectify the outdoor air that has flowed into the housing 15 so that it passes through the collection plate 2.
　第１のバッフル材１８は、筐体１５の上面１５ａの内面側に配置されている。第１のバッフル材１８は、捕集板２の外周面に沿う面形状を有する。第２のバッフル材１９は、筐体１５の下面１５ｂの内面側に配置されている。第２のバッフル材１９は、平坦な面形状を有する。また、第２のバッフル材１９は、ダストボックス４へ空気が衝突して生じる騒音を抑制する。さらに、第２のバッフル材１９は、ダストボックス４内部への空気流入によってダストボックス４内に回収した塵埃が舞い上がることを抑制する。このため、第２のバッフル材１９の配置位置は、ダストボックス４の先端部４ａと同等以上の高さであることが望ましい。 The first baffle material 18 is arranged on the inner surface side of the upper surface 15a of the housing 15. The first baffle material 18 has a surface shape along the outer peripheral surface of the collecting plate 2. The second baffle material 19 is arranged on the inner surface side of the lower surface 15b of the housing 15. The second baffle material 19 has a flat surface shape. Further, the second baffle material 19 suppresses noise generated by collision of air with the dust box 4. Further, the second baffle material 19 suppresses the dust collected in the dust box 4 from flying up due to the inflow of air into the dust box 4. Therefore, it is desirable that the second baffle material 19 is arranged at a height equal to or higher than the tip portion 4a of the dust box 4.
　集塵装置本体１は、モーター６及び駆動制御部７をさらに備えている。モーター６及び駆動制御部７は、筐体１５の外に設けられている。モーター６は、図示しないギアを介して第１のシャフト８に連結されている。モーター６の回転により第１のシャフト８が回転する。第１のシャフト８が回転すると、第１のシャフト８に固定された捕集板２も回転する。駆動制御部７は、モーター６の回転を制御することで、捕集板２の回転駆動を制御する。 The dust collector main body 1 further includes a motor 6 and a drive control unit 7. The motor 6 and the drive control unit 7 are provided outside the housing 15. The motor 6 is connected to the first shaft 8 via a gear (not shown). The rotation of the motor 6 causes the first shaft 8 to rotate. When the first shaft 8 rotates, the collection plate 2 fixed to the first shaft 8 also rotates. The drive control unit 7 controls the rotation drive of the collection plate 2 by controlling the rotation of the motor 6.
　次に、以上のように構成された集塵装置本体１の動作について説明する。集塵装置本体１を初めて又は１ケ月以上の長期間停止した後、運転する場合、捕集板２の表面に静電気を帯電させるための摩擦帯電動作を行う。すなわち、集塵装置本体１の駆動制御部７は、モーター６を動作させることで捕集板２を回転させる。ここでは、捕集板２を１ｒｐｍの速さで２０秒間、正回転（図２の矢印１２方向の回転）させる。捕集板２が回転して捕集板２の表面がブラシ３と擦れることで、捕集板２の表面に負の静電気が発生する。捕集板２の回転が停止すると摩擦帯電が完了し、摩擦帯電動作が終了する。なお、捕集板２の回転は、静電気が発生するように行えばよい。ここで示した回転速度及び回転時間等は一例であり、実使用条件等に応じて適宜設定すればよい。 Next, the operation of the dust collector main body 1 configured as described above will be described. When the dust collector main body 1 is operated for the first time or after being stopped for a long period of one month or more, a triboelectric charging operation is performed to charge the surface of the dust collector plate 2 with static electricity. That is, the drive control unit 7 of the dust collector main body 1 rotates the collection plate 2 by operating the motor 6. Here, the collecting plate 2 is rotated forward (rotated in the direction of the arrow 12 in FIG. 2) at a speed of 1 rpm for 20 seconds. When the collection plate 2 rotates and the surface of the collection plate 2 rubs against the brush 3, negative static electricity is generated on the surface of the collection plate 2. When the rotation of the collecting plate 2 is stopped, the triboelectric charging is completed and the triboelectric charging operation is completed. The collection plate 2 may be rotated so that static electricity is generated. The rotation speed, rotation time, and the like shown here are examples, and may be appropriately set according to actual usage conditions and the like.
　摩擦帯電動作後、室外空気が集塵装置本体１内に取り込まれると、室外空気は、第１のバッフル材１８及び第２のバッフル材１９により整流されて捕集板２間の中心部を通過する。捕集板２間を室外空気が通過する際、室外空気中の塵埃５が、捕集板２の表面に発生した静電気によって捕集板２の表面に捕集される。ここで、ブラシ３は空気の通過方向に沿った姿勢で、例えば空気の通過方向に平行な姿勢で捕集板２間に配置されている。このため、捕集板２間を通過する室外空気の流れを大きく阻害せず、通風抵抗が小さい。よって、高い集塵性能を得ることができる。 When the outdoor air is taken into the dust collector main body 1 after the triboelectric charging operation, the outdoor air is rectified by the first baffle material 18 and the second baffle material 19 and passes through the central portion between the collection plates 2. To do. When the outdoor air passes between the collection plates 2, the dust 5 in the outdoor air is collected on the surface of the collection plate 2 by the static electricity generated on the surface of the collection plate 2. Here, the brush 3 is arranged between the collection plates 2 in a posture along the air passing direction, for example, in a posture parallel to the air passing direction. Therefore, the flow of outdoor air passing between the collection plates 2 is not significantly obstructed, and the ventilation resistance is small. Therefore, high dust collection performance can be obtained.
　また、集塵装置本体１の動作として、捕集板２の自動表面清掃及び自動再帯電動作（以下、清掃兼帯電動作という）がある。清掃兼帯電動作では、まず、前述した初期の摩擦帯電動作と同様、集塵装置本体１の駆動制御部７からモーター６への命令により、捕集板２を１ｒｐｍの速さで２０秒間、正回転させる。捕集板２が回転して捕集板２の表面がブラシ３と擦れることで、捕集板２の表面に付着した塵埃がブラシ３により払い落とされるとともに、捕集板２が摩擦帯電する。つまり、捕集板２の回転により、付着した塵埃の払い落としと捕集板２の摩擦帯電との両方が行われる。なお、ブラシ３の下部には塵埃の一部が凝集体１７となって付着する。ブラシ３の下部に付着した凝集体１７が一定以上の大きさになると、重力で落下してダストボックス４に回収される。 Further, as the operation of the dust collector main body 1, there are automatic surface cleaning and automatic recharging operation of the collecting plate 2 (hereinafter referred to as cleaning and charging operation). In the cleaning and charging operation, first, as in the initial triboelectric charging operation described above, the collection plate 2 is positively charged at a speed of 1 rpm for 20 seconds by a command from the drive control unit 7 of the dust collector main body 1 to the motor 6. Rotate. When the collection plate 2 rotates and the surface of the collection plate 2 rubs against the brush 3, the dust adhering to the surface of the collection plate 2 is wiped off by the brush 3, and the collection plate 2 is triboelectrically charged. That is, the rotation of the collection plate 2 causes both the dust adhering to be removed and the triboelectric charge of the collection plate 2 to be performed. A part of the dust adheres to the lower part of the brush 3 as an agglomerate 17. When the agglomerates 17 adhering to the lower part of the brush 3 have a certain size or more, they fall by gravity and are collected in the dust box 4.
　次に、以上のように構成された集塵装置本体１を搭載した空気調和機の動作について説明する。集塵装置本体１の前述した初期の摩擦帯電動作が必要な場合、連携制御部２５は、熱交換換気装置１０のファンを停止させた状態で、駆動制御部７に指令信号を出力して前述した初期の摩擦帯電動作を行わせる。 Next, the operation of the air conditioner equipped with the dust collector main body 1 configured as described above will be described. When the above-mentioned initial triboelectric operation of the dust collector main body 1 is required, the cooperation control unit 25 outputs a command signal to the drive control unit 7 with the fan of the heat exchange ventilation device 10 stopped, and is described above. The initial triboelectric charging operation is performed.
　そして、初期の摩擦帯電動作が終了すると、換気を開始する。つまり、連携制御部２５は、熱交換換気装置１０のファンを運転させる。これにより、室外から取り込まれた室外空気が集塵装置本体１を通過して室外空気中の塵埃が除去される。塵埃が除去された空気は、熱交換換気装置１０に供給される。熱交換換気装置１０に供給された室外空気は、室内排気口２３を介して熱交換換気装置１０に流入した室内空気と熱交換して熱回収し、室内給気口２４から室内に供給される。 Then, when the initial triboelectric operation is completed, ventilation is started. That is, the cooperative control unit 25 operates the fan of the heat exchange ventilation device 10. As a result, the outdoor air taken in from the outside passes through the dust collector main body 1 and the dust in the outdoor air is removed. The air from which the dust has been removed is supplied to the heat exchange ventilation device 10. The outdoor air supplied to the heat exchange ventilation device 10 exchanges heat with the indoor air flowing into the heat exchange ventilation device 10 through the indoor exhaust port 23 to recover heat, and is supplied to the room from the indoor air supply port 24. ..
　連携制御部２５は、集塵装置本体１に配置された第１のパーティクルセンサ１１ａ及び第２のパーティクルセンサ１１ｂのそれぞれからの検出信号に基づいて、集塵装置本体１の集塵性能の低下をチェックしている。連携制御部２５は、各検出信号に基づいて集塵装置本体１の集塵性能の低下を検知すると、熱交換換気装置１０のファンを停止させる。そして、連携制御部２５は、空気の流れを停止した状態で集塵装置本体１に前述の清掃兼帯電動作を行わせる。清掃兼帯電動作により、捕集板２の集塵性能が復活すると、再び捕集板２で塵埃の捕集が行われる。 The cooperative control unit 25 reduces the dust collection performance of the dust collector main body 1 based on the detection signals from each of the first particle sensor 11a and the second particle sensor 11b arranged in the dust collector main body 1. I'm checking. When the cooperative control unit 25 detects a decrease in the dust collection performance of the dust collector main body 1 based on each detection signal, the cooperative control unit 25 stops the fan of the heat exchange ventilation device 10. Then, the cooperation control unit 25 causes the dust collector main body 1 to perform the above-mentioned cleaning and charging operation in a state where the air flow is stopped. When the dust collecting performance of the collecting plate 2 is restored by the cleaning and charging operation, the dust collecting plate 2 collects the dust again.
　なお、第１のパーティクルセンサ１１ａ及び第２のパーティクルセンサ１１ｂからの検出信号に基づく集塵装置本体１の集塵性能の低下の検知は、例えば以下のようにすればよい。すなわち、集塵装置本体１の通過前後の塵埃濃度の差が、予め設定された濃度以下となった場合、集塵装置本体１の集塵性能の低下と判断すればよい。 Note that the deterioration of the dust collection performance of the dust collector main body 1 based on the detection signals from the first particle sensor 11a and the second particle sensor 11b may be detected as follows, for example. That is, when the difference in dust concentration before and after passing through the dust collector main body 1 is equal to or less than a preset concentration, it may be determined that the dust collection performance of the dust collector main body 1 is deteriorated.
　以上においては、捕集板２を負に帯電する例で説明した。しかし、この点については、これに限られない。他に例えば、捕集板２の繊維をＰＡ６としたり、捕集板２の摩擦体の材料に負帯電傾向の強いＰＴＦＥを用いたりして、捕集板２を正に帯電してもよい。ただし、捕集板２を負に帯電する場合は、ブラシ３は正に帯電しやすい素材にするとよい。また、逆に、捕集板２を正に帯電する場合は、ブラシ３は負に帯電しやすい素材にするとよい。 In the above, the example in which the collection plate 2 is negatively charged has been described. However, this point is not limited to this. Alternatively, for example, the fiber of the collecting plate 2 may be PA6, or PTFE having a strong negative charging tendency may be used as the material of the friction body of the collecting plate 2, so that the collecting plate 2 may be positively charged. However, when the collection plate 2 is negatively charged, the brush 3 may be made of a material that is easily positively charged. On the contrary, when the collecting plate 2 is positively charged, the brush 3 may be made of a material that is easily negatively charged.
　また、ブラシ３の繊維がＰＡ６繊維である例を示したが、ブラシ３の繊維にＰＡＮ（Ｐｏｌｙａｃｒｙｌｏｎｉｔｒｉｌｅ）繊維等を用いてもよい。ブラシ３の帯電飽和を抑制するためには、摩擦体の導電性は高い方が好ましく、ブラシ３の繊維に炭素を付与した材料を用いる等して導電性を付与してもよい。また、ブラシ３は不織布状以外にも、はけ状、スポンジ状又は板状等であってもよい。 Further, although the example in which the fiber of the brush 3 is a PA6 fiber is shown, a PAN (Polyacrylonitrile) fiber or the like may be used as the fiber of the brush 3. In order to suppress the charge saturation of the brush 3, it is preferable that the friction body has high conductivity, and the conductivity may be imparted by using a material in which carbon is imparted to the fibers of the brush 3. In addition to the non-woven fabric shape, the brush 3 may have a brush shape, a sponge shape, a plate shape, or the like.
　また、ここで説明した構成例では、ブラシ３は捕集板２の下流側から上流側に向け捕集板２の間隔に差し込まれている。しかし、この点については、これに限られない。ブラシ３は、捕集板２の上流側から下流側に向け捕集板２の間隔に差し込まれていてもよい。この場合、ダストボックス４も同様にブラシ３の鉛直下方に配置すればよい。 Further, in the configuration example described here, the brush 3 is inserted at the interval of the collection plate 2 from the downstream side to the upstream side of the collection plate 2. However, this point is not limited to this. The brush 3 may be inserted at intervals of the collection plate 2 from the upstream side to the downstream side of the collection plate 2. In this case, the dust box 4 may be similarly arranged vertically below the brush 3.
　次に、図４も参照しながら、この実施の形態の集塵装置について説明を続ける。この実施の形態の捕集板２は、第１の清掃部１０１である。第１の清掃部１０１である捕集板２は、清掃対象である室外空気と接触可能に設けられている。そして、第１の清掃部１０１である捕集板２は、塵埃を捕集板２自身に付着させて清掃対象である室外空気から塵埃を除去する。 Next, the dust collector of this embodiment will be described with reference to FIG. The collecting plate 2 of this embodiment is a first cleaning unit 101. The collection plate 2, which is the first cleaning unit 101, is provided so as to be in contact with the outdoor air to be cleaned. Then, the collecting plate 2 which is the first cleaning unit 101 attaches dust to the collecting plate 2 itself and removes the dust from the outdoor air to be cleaned.
　この実施の形態のモーター６及び駆動制御部７は、回転駆動部１０２である。回転駆動部１０２であるモーター６及び駆動制御部７は、第１の清掃部１０１である捕集板２を第１の方向に回転させる。第１の方向とは、前述した正回転の方向である。すなわち、図１中に矢印１２で示す方向が第１の方向である。 The motor 6 and the drive control unit 7 of this embodiment are the rotary drive unit 102. The motor 6 and the drive control unit 7, which are the rotation drive units 102, rotate the collection plate 2, which is the first cleaning unit 101, in the first direction. The first direction is the direction of forward rotation described above. That is, the direction indicated by the arrow 12 in FIG. 1 is the first direction.
　この実施の形態のブラシ３は、第２の清掃部１０６である。第２の清掃部１０６であるブラシ３は、前述した第１の方向に回転する第１の清掃部１０１（捕集板２）と接触して設けられている。そして、第２の清掃部１０６であるブラシ３は、第１の清掃部１０１である捕集板２に付着した塵埃を除去する。すなわち、第２の清掃部１０６が第１の清掃部１０１に接続した状態で、回転駆動部１０２が第１の清掃部１０１を第１の方向に回転させることで、清掃対象の塵埃を第１の清掃部１０１に付着させると同時に、第１の清掃部１０１に付着した塵埃が第２の清掃部１０６により除去される。この際、第１の清掃部１０１に付着していた塵埃の一部は、第２の清掃部１０６により払われて脱落する。また、第１の清掃部１０１に付着していた塵埃の他の一部は、第２の清掃部１０６に付着する。 The brush 3 of this embodiment is the second cleaning unit 106. The brush 3, which is the second cleaning unit 106, is provided in contact with the first cleaning unit 101 (collecting plate 2) that rotates in the first direction described above. Then, the brush 3 which is the second cleaning unit 106 removes the dust adhering to the collection plate 2 which is the first cleaning unit 101. That is, with the second cleaning unit 106 connected to the first cleaning unit 101, the rotation driving unit 102 rotates the first cleaning unit 101 in the first direction to remove dust to be cleaned. At the same time as adhering to the cleaning unit 101, the dust adhering to the first cleaning unit 101 is removed by the second cleaning unit 106. At this time, a part of the dust adhering to the first cleaning unit 101 is removed by the second cleaning unit 106 and falls off. Further, the other part of the dust adhering to the first cleaning unit 101 adheres to the second cleaning unit 106.
　回転駆動部１０２であるモーター６及び駆動制御部７は、集塵装置本体１に反転動作を行わせる。反転動作とは、第１の清掃部１０１と第２の清掃部１０６とが接触した状態で第１の清掃部１０１を第２の方向に回転させて第２の清掃部１０６に付着した塵埃を脱落させる動作である。第２の方向は、第１の方向と反対の方向である。すなわち、反転動作において、回転駆動部１０２は第１の清掃部１０１を前述した正回転とは反対に逆回転させる。 The motor 6 and the drive control unit 7, which are the rotation drive units 102, cause the dust collector main body 1 to perform a reverse operation. The reversing operation is a state in which the first cleaning unit 101 and the second cleaning unit 106 are in contact with each other, and the first cleaning unit 101 is rotated in the second direction to remove dust adhering to the second cleaning unit 106. It is an action to drop off. The second direction is the direction opposite to the first direction. That is, in the reversing operation, the rotation driving unit 102 rotates the first cleaning unit 101 in the opposite direction to the forward rotation described above.
　集塵装置本体１が清掃対象から塵埃を除去する集塵動作を開始すると、回転駆動部１０２は第１の清掃部１０１を第１の方向に回転させる。そして、集塵動作を開始してから予め設定された運転時間が経過すると、集塵装置本体１は集塵動作を終了する。回転駆動部１０２は、集塵動作を終了する前に、第１の清掃部１０１を第２の方向に回転させる反転動作を行わせる。 When the dust collector main body 1 starts the dust collecting operation for removing dust from the cleaning target, the rotation driving unit 102 rotates the first cleaning unit 101 in the first direction. Then, when a preset operation time elapses from the start of the dust collecting operation, the dust collecting device main body 1 ends the dust collecting operation. The rotation driving unit 102 causes the first cleaning unit 101 to perform a reversing operation of rotating the first cleaning unit 101 in the second direction before the dust collecting operation is completed.
　この実施の形態の集塵装置本体１においては、前述したように、第１の清掃部１０１を第１の方向に回転させることで、清掃対象の塵埃を第１の清掃部１０１に付着させて清掃対象から取り除きつつ、第１の清掃部１０１に付着した塵埃は、第２の清掃部１０６により第１の清掃部１０１から取り除かれる。このため、長時間にわたって第１の清掃部１０１により清掃対象の塵埃を除去できる。一方、第２の清掃部１０６により第１の清掃部１０１から取り除かれた塵埃の一部は、第２の清掃部１０６に付着する。このため、第１の清掃部１０１を第１の方向に回転させる時間が長くなると、第２の清掃部１０６に付着した塵埃が蓄積する。 In the dust collector main body 1 of this embodiment, as described above, by rotating the first cleaning unit 101 in the first direction, the dust to be cleaned is attached to the first cleaning unit 101. Dust adhering to the first cleaning unit 101 while being removed from the cleaning target is removed from the first cleaning unit 101 by the second cleaning unit 106. Therefore, the dust to be cleaned can be removed by the first cleaning unit 101 for a long time. On the other hand, a part of the dust removed from the first cleaning unit 101 by the second cleaning unit 106 adheres to the second cleaning unit 106. Therefore, if the time for rotating the first cleaning unit 101 in the first direction becomes longer, the dust adhering to the second cleaning unit 106 accumulates.
　この実施の形態の集塵装置によれば、前述した反転動作を行うことで、第２の清掃部１０６に付着した塵埃を第１の清掃部１０１との摩擦により取り除くことができる。このため、人為的なメンテナンス作業を行わずとも、第１の清掃部１０１のみならず第２の清掃部１０６への塵埃の蓄積を抑制でき、集塵性能の低下を抑制して、集塵可能な期間を長くすることが可能である。 According to the dust collector of this embodiment, the dust adhering to the second cleaning unit 106 can be removed by friction with the first cleaning unit 101 by performing the above-mentioned reversing operation. Therefore, it is possible to suppress the accumulation of dust not only in the first cleaning unit 101 but also in the second cleaning unit 106 without performing artificial maintenance work, and it is possible to suppress the deterioration of the dust collection performance and collect the dust. It is possible to lengthen the period.
　この実施の形態のダストボックス４は、集塵部である。集塵部であるダストボックス４は、第１の清掃部である捕集板２及び第２の清掃部１０６であるブラシ３から脱落した塵埃を捕集する。すなわち、第１の清掃部１０１が第１の方向に回転している時は、主に第２の清掃部１０６により第１の清掃部１０１から払い落とされた塵埃が集塵部で捕集される。そして、前述の反転動作中には、第２の清掃部１０６から脱落した塵埃が集塵部で捕集される。 The dust box 4 of this embodiment is a dust collecting unit. The dust box 4, which is a dust collecting unit, collects dust that has fallen off from the collecting plate 2 which is the first cleaning unit and the brush 3 which is the second cleaning unit 106. That is, when the first cleaning unit 101 is rotating in the first direction, the dust that has been wiped off from the first cleaning unit 101 by the second cleaning unit 106 is mainly collected by the dust collecting unit. To. Then, during the above-mentioned reversing operation, the dust that has fallen off from the second cleaning unit 106 is collected by the dust collecting unit.
　この実施の形態における清掃対象は、前述したように室外空気である。すなわち、この清掃対象は、第１の清掃部１０１である捕集板２の周囲を流れる流体である。そして、この実施の形態における熱交換換気装置１０のファンは、流れ生成装置１０４である。流れ生成装置１０４である熱交換換気装置１０のファンは、清掃対象である流体の流れを生成する。 The cleaning target in this embodiment is outdoor air as described above. That is, the cleaning target is a fluid flowing around the collecting plate 2 which is the first cleaning unit 101. The fan of the heat exchange ventilation device 10 in this embodiment is the flow generator 104. The fan of the heat exchange ventilator 10 which is the flow generator 104 generates a flow of the fluid to be cleaned.
　流れ生成装置１０４は、回転駆動部１０２による第１の清掃部１０１の動作状況に応じて、清掃対象である流体の流れの速さを変更する。具体的に、この実施の形態では、流れ生成装置１０４は、前述の反転動作中において、清掃対象である流体の流れの生成を停止する。あるいは、流れ生成装置１０４は、前述の反転動作中において、清掃対象である流体の流れの速さを当該反転動作前よりも遅くする。 The flow generator 104 changes the flow speed of the fluid to be cleaned according to the operating status of the first cleaning unit 101 by the rotation drive unit 102. Specifically, in this embodiment, the flow generator 104 stops the generation of the flow of the fluid to be cleaned during the above-mentioned reversing operation. Alternatively, the flow generator 104 makes the flow speed of the fluid to be cleaned slower than before the reversing operation during the reversing operation described above.
　前述したように、この実施の形態の集塵装置本体１においては、集塵部であるダストボックス４は、第２の清掃部１０６であるブラシ３に対して鉛直下方側に配置されている。そこで、前述の反転動作中において、熱交換換気装置１０のファンの回転を停止させる、又は、回転数を下げることで、ブラシ３の周囲の空気流をなくし、又は、弱くする。このようにすることで、前述の反転動作中においてブラシ３（第２の清掃部１０６）から脱落した塵埃がダストボックス４（集塵部）内に入りやすくできる。 As described above, in the dust collector main body 1 of this embodiment, the dust box 4 which is a dust collecting part is arranged vertically downward with respect to the brush 3 which is the second cleaning part 106. Therefore, during the above-mentioned reversal operation, the rotation of the fan of the heat exchange ventilation device 10 is stopped or the rotation speed is reduced to eliminate or weaken the air flow around the brush 3. By doing so, the dust that has fallen off from the brush 3 (second cleaning portion 106) during the above-mentioned reversing operation can easily enter the dust box 4 (dust collecting portion).
　図４に示すように、この実施の形態の集塵装置は、塵埃除去性能低下判定部１０３及び報知部１０５をさらに備えている。塵埃除去性能低下判定部１０３は、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能の低下を判定する。次に、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能の低下を塵埃除去性能低下判定部１０３が判定する方法について、いくつかの例を説明する。 As shown in FIG. 4, the dust collector of this embodiment further includes a dust removal performance deterioration determination unit 103 and a notification unit 105. The dust removal performance deterioration determination unit 103 determines the deterioration of the dust removal performance of the dust adhering to the first cleaning unit 101 by the second cleaning unit 106. Next, some examples will be described of a method in which the dust removal performance deterioration determination unit 103 determines the deterioration of the dust removal performance of the first cleaning unit 101 by the second cleaning unit 106.
　まず、第１の例は、第２の清掃部１０６であるブラシ３に付着した塵埃の量が予め設定された基準量以上となった場合に、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能が低下したと塵埃除去性能低下判定部１０３が判定するものである。第２の清掃部１０６に付着した塵埃が蓄積すると、第２の清掃部１０６により第１の清掃部１０１に付着した塵埃を除去する性能が低下する。そこで、第２の清掃部１０６に付着した塵埃の量を検出し、第２の清掃部１０６に付着した塵埃の検出量が一定以上となった場合に、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能が低下したと判定する。 First, in the first example, when the amount of dust adhering to the brush 3 which is the second cleaning unit 106 becomes equal to or more than a preset reference amount, the first cleaning unit by the second cleaning unit 106 The dust removal performance deterioration determination unit 103 determines that the dust removal performance of the dust adhering to the 101 has deteriorated. When the dust adhering to the second cleaning unit 106 accumulates, the performance of removing the dust adhering to the first cleaning unit 101 by the second cleaning unit 106 deteriorates. Therefore, the amount of dust adhering to the second cleaning unit 106 is detected, and when the amount of dust adhering to the second cleaning unit 106 exceeds a certain level, the first cleaning unit 106 first detects the amount of dust. It is determined that the dust removing performance of the dust adhering to the cleaning unit 101 has deteriorated.
　この例では、塵埃除去性能低下判定部１０３は、第２の清掃部１０６であるブラシ３に付着した塵埃の量を検出する塵埃センサを備えている。塵埃センサは、例えば、赤外線等を第２の清掃部１０６であるブラシ３に照射し、その反射率から塵埃の量を測定する。なお、塵埃除去性能低下判定部１０３は、他に例えば、第２の清掃部１０６を摩擦した際に摩擦熱により生じる摩擦部位の特性変化を利用して第２の清掃部１０６に付着した塵埃の量を求めてもよい。 In this example, the dust removal performance deterioration determination unit 103 includes a dust sensor that detects the amount of dust adhering to the brush 3, which is the second cleaning unit 106. The dust sensor, for example, irradiates the brush 3 which is the second cleaning unit 106 with infrared rays or the like, and measures the amount of dust from the reflectance. In addition, the dust removal performance deterioration determination unit 103 also utilizes, for example, a change in the characteristics of the friction portion generated by frictional heat when the second cleaning unit 106 is rubbed, to collect dust adhering to the second cleaning unit 106. You may ask for the amount.
　第２の例は、回転駆動部１０２が第１の清掃部１０１を回転させる時にかかるトルクの変化に基づいて、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能の低下を塵埃除去性能低下判定部１０３が判定するものである。第２の清掃部１０６に付着した塵埃が蓄積して、第２の清掃部１０６により第１の清掃部１０１に付着した塵埃を除去する性能が低下すると、第２の清掃部１０６に付着した塵埃が抵抗となり、回転駆動部１０２が第１の清掃部１０１を回転させる時にかかるトルクが増加する。この例では、塵埃除去性能低下判定部１０３は、回転駆動部１０２のトルクを検出するトルクセンサを備えている。そして、回転駆動部１０２のトルクが予め設定された基準値以上になった場合に、第１の清掃部１０１に付着した塵埃の第２の清掃部１０６による除去性能が低下したと塵埃除去性能低下判定部１０３が判定する。 In the second example, the performance of removing dust adhering to the first cleaning unit 101 by the second cleaning unit 106 based on the change in torque applied when the rotation driving unit 102 rotates the first cleaning unit 101. The dust removal performance deterioration determination unit 103 determines the decrease. When the dust adhering to the second cleaning unit 106 accumulates and the performance of removing the dust adhering to the first cleaning unit 101 by the second cleaning unit 106 deteriorates, the dust adhering to the second cleaning unit 106 deteriorates. Becomes a resistance, and the torque applied when the rotation drive unit 102 rotates the first cleaning unit 101 increases. In this example, the dust removal performance deterioration determination unit 103 includes a torque sensor that detects the torque of the rotation drive unit 102. Then, when the torque of the rotary drive unit 102 becomes equal to or higher than a preset reference value, the dust removal performance deteriorates when the removal performance of the dust adhering to the first cleaning unit 101 by the second cleaning unit 106 deteriorates. The determination unit 103 determines.
　第３の例は、流れ生成装置１０４の動作時間に基づいて、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能の低下を塵埃除去性能低下判定部１０３が判定するものである。流れ生成装置１０４の動作時間が長くなると、第２の清掃部１０６に付着した塵埃が蓄積して、第２の清掃部１０６により第１の清掃部１０１に付着した塵埃を除去する性能が低下する。 In the third example, the dust removal performance deterioration determination unit 103 determines that the dust removal performance of the second cleaning unit 106 has deteriorated in the dust removal performance of the first cleaning unit 101 based on the operating time of the flow generator 104. It is a thing. When the operation time of the flow generator 104 becomes long, the dust adhering to the second cleaning unit 106 accumulates, and the ability of the second cleaning unit 106 to remove the dust adhering to the first cleaning unit 101 deteriorates. ..
　そこで、まず、集塵装置本体１の設置環境における流れ生成装置１０４の動作時間と第２の清掃部１０６であるブラシ３の塵埃付着量との関係を実験、シミュレーション等で予め特定する。次に、この関係を用いて、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能が低下したとみなす流れ生成装置１０４の動作時間を、基準時間として設定する。そして、流れ生成装置１０４の動作時間が、この予め設定された基準時間以上となった場合に、第１の清掃部１０１に付着した塵埃の第２の清掃部１０６による除去性能が低下したと塵埃除去性能低下判定部１０３が判定する。 Therefore, first, the relationship between the operating time of the flow generator 104 in the installation environment of the dust collector main body 1 and the amount of dust adhering to the brush 3 which is the second cleaning unit 106 is specified in advance by experiments, simulations, and the like. Next, using this relationship, the operating time of the flow generator 104, which is considered to have deteriorated in the performance of removing dust adhering to the first cleaning unit 101 by the second cleaning unit 106, is set as a reference time. Then, when the operating time of the flow generator 104 becomes equal to or longer than the preset reference time, the dust removal performance of the dust adhering to the first cleaning unit 101 by the second cleaning unit 106 is deteriorated. The removal performance deterioration determination unit 103 determines.
　第４の例は、集塵装置本体１の設置環境における塵埃等の量に関する情報を外部から取得し、この取得した情報（以下、「外部情報」ともいう）に基づいて、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能の低下を塵埃除去性能低下判定部１０３が判定するものである。塵埃除去性能低下判定部１０３は、例えば、インターネットを介して外部と通信可能に接続されている。塵埃除去性能低下判定部１０３は、外部情報として、例えば、花粉情報、ＰＭ２．５情報等を取得する。そして、塵埃除去性能低下判定部１０３は、取得した外部情報と流れ生成装置１０４の流量とを用いて、第２の清掃部１０６であるブラシ３への塵埃の付着量を推定する。塵埃除去性能低下判定部１０３は、こうして推定した第２の清掃部１０６の塵埃の付着量が予め設定された基準量以上となった場合に、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能が低下したと判定する。 In the fourth example, information on the amount of dust and the like in the installation environment of the dust collector main body 1 is acquired from the outside, and based on the acquired information (hereinafter, also referred to as “external information”), the second cleaning unit The dust removal performance deterioration determination unit 103 determines the deterioration of the dust removal performance of the dust adhering to the first cleaning unit 101 by 106. The dust removal performance deterioration determination unit 103 is connected so as to be able to communicate with the outside via, for example, the Internet. The dust removal performance deterioration determination unit 103 acquires, for example, pollen information, PM2.5 information, and the like as external information. Then, the dust removal performance deterioration determination unit 103 estimates the amount of dust adhering to the brush 3, which is the second cleaning unit 106, by using the acquired external information and the flow rate of the flow generator 104. When the amount of dust adhering to the second cleaning unit 106 estimated in this way exceeds a preset reference amount, the dust removal performance deterioration determination unit 103 uses the second cleaning unit 106 to perform the first cleaning unit 101. It is determined that the performance of removing dust adhering to the surface has deteriorated.
　第５の例は、ダストボックス４に蓄積された塵埃の量に基づいて、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能の低下を塵埃除去性能低下判定部１０３が判定するものである。集塵装置本体１の集塵性能が低下しているとき、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能も低下している可能性が高い。そこで、例えば一定時間内にダストボックス４に蓄積される塵埃の量に基づいて集塵装置本体１の集塵性能の低下をチェックし、集塵装置本体１の集塵性能の低下した場合に第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能も低下していると推定する。 In the fifth example, the dust removal performance deterioration determination unit 103 determines that the dust removal performance of the second cleaning unit 106 deteriorates in the dust removal performance of the first cleaning unit 101 based on the amount of dust accumulated in the dust box 4. It is a judgment. When the dust collecting performance of the dust collector main body 1 is deteriorated, it is highly possible that the dust collecting performance of the second cleaning unit 106 also deteriorates in removing the dust adhering to the first cleaning unit 101. Therefore, for example, a deterioration in the dust collection performance of the dust collector main body 1 is checked based on the amount of dust accumulated in the dust box 4 within a certain period of time, and when the dust collection performance of the dust collector main body 1 deteriorates, a second It is presumed that the performance of removing dust adhering to the first cleaning unit 101 by the cleaning unit 106 is also deteriorated.
　この例では、塵埃除去性能低下判定部１０３は、ダストボックス４に蓄積された塵埃の量を検出するセンサを備えている。塵埃除去性能低下判定部１０３は、センサの検出結果を用いて、集塵装置本体１の１回の動作毎、又は、予め設定された一定時間毎のダストボックス４に蓄積された塵埃の量の増加分を求める。そして、ダストボックス４に蓄積された塵埃の量の増加分が、過去よりも一定以上減少した場合に、第１の清掃部１０１に付着した塵埃の第２の清掃部１０６による除去性能が低下したと塵埃除去性能低下判定部１０３が判定する。 In this example, the dust removal performance deterioration determination unit 103 includes a sensor that detects the amount of dust accumulated in the dust box 4. The dust removal performance deterioration determination unit 103 uses the detection result of the sensor to increase the amount of dust accumulated in the dust box 4 for each operation of the dust collector main body 1 or for each preset fixed time. Ask for minutes. Then, when the increase in the amount of dust accumulated in the dust box 4 decreases by a certain amount or more from the past, the removal performance of the dust adhering to the first cleaning unit 101 by the second cleaning unit 106 deteriorates. The dust removal performance deterioration determination unit 103 determines.
　第６の例は、集塵装置本体１に設けられた第１のパーティクルセンサ１１ａ及び第２のパーティクルセンサ１１ｂのそれぞれからの検出信号に基づいて、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能の低下を塵埃除去性能低下判定部１０３が判定するものである。前述したように、連携制御部２５は、第１のパーティクルセンサ１１ａ及び第２のパーティクルセンサ１１ｂのそれぞれからの検出信号に基づいて、集塵装置本体１の集塵性能の低下をチェックしている。集塵装置本体１の集塵性能が低下しているとき、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能も低下している可能性が高い。そこで、塵埃除去性能低下判定部１０３は、第１のパーティクルセンサ１１ａ及び第２のパーティクルセンサ１１ｂからの検出信号に基づき集塵装置本体１の集塵性能の低下を連携制御部２５が検知した場合に、第１の清掃部１０１に付着した塵埃の第２の清掃部１０６による除去性能が低下したと判定する。 In the sixth example, the first cleaning unit by the second cleaning unit 106 is based on the detection signals from each of the first particle sensor 11a and the second particle sensor 11b provided in the dust collector main body 1. The dust removal performance deterioration determination unit 103 determines the deterioration of the dust removal performance of the dust adhering to the 101. As described above, the cooperation control unit 25 checks the deterioration of the dust collection performance of the dust collector main body 1 based on the detection signals from each of the first particle sensor 11a and the second particle sensor 11b. .. When the dust collecting performance of the dust collector main body 1 is deteriorated, it is highly possible that the dust collecting performance of the second cleaning unit 106 also deteriorates in removing the dust adhering to the first cleaning unit 101. Therefore, when the dust removal performance deterioration determination unit 103 detects a deterioration in the dust collection performance of the dust collector main body 1 based on the detection signals from the first particle sensor 11a and the second particle sensor 11b, the cooperation control unit 25 detects it. In addition, it is determined that the removal performance of the dust adhering to the first cleaning unit 101 by the second cleaning unit 106 has deteriorated.
　第７の例は、集塵装置本体１の筐体１５を通過する風量又は風速に基づいて、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能の低下を塵埃除去性能低下判定部１０３が判定するものである。第２の清掃部１０６に付着した塵埃が蓄積して、第２の清掃部１０６により第１の清掃部１０１に付着した塵埃を除去する性能が低下すると、第１の清掃部１０１である捕集板２に蓄積した塵埃により、筐体１５を通過する空気の流れが阻害される。この例では、塵埃除去性能低下判定部１０３は、例えば、筐体１５の排出口１４における風量を検出する風量センサ又は風速を検出する風速センサを備えている。そして、筐体１５の排出口１４における風量又は風速が予め設定された基準値以上になった場合に、第１の清掃部１０１に付着した塵埃の第２の清掃部１０６による除去性能が低下したと塵埃除去性能低下判定部１０３が判定する。 In the seventh example, the deterioration of the dust removing performance of the second cleaning unit 106 adhering to the first cleaning unit 101 is removed based on the air volume or the wind speed passing through the housing 15 of the dust collector main body 1. The performance deterioration determination unit 103 determines. When the dust adhering to the second cleaning unit 106 accumulates and the performance of removing the dust adhering to the first cleaning unit 101 is deteriorated by the second cleaning unit 106, the first cleaning unit 101 collects the dust. The dust accumulated on the plate 2 obstructs the flow of air passing through the housing 15. In this example, the dust removal performance deterioration determination unit 103 includes, for example, an air volume sensor that detects the air volume at the discharge port 14 of the housing 15 or a wind speed sensor that detects the wind speed. Then, when the air volume or the wind speed at the discharge port 14 of the housing 15 exceeds a preset reference value, the removal performance of the dust adhering to the first cleaning unit 101 by the second cleaning unit 106 is deteriorated. The dust removal performance deterioration determination unit 103 determines.
　第８の例は、前述した摩擦帯電動作後における捕集板２の表面の帯電量に基づいて、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能の低下を塵埃除去性能低下判定部１０３が判定するものである。第２の清掃部１０６であるブラシ３に付着した塵埃が蓄積すると、ブラシ３で捕集板２の表面を十分に摩擦できなくなる。このため、前述の摩擦帯電動作後における捕集板２の表面の帯電量が、通常時よりも低下する。この例では、塵埃除去性能低下判定部１０３は、例えば、捕集板２表面の電位を検出する表面電位センサを備えている。筐体１５の排出口１４における風量を検出する風量センサ又は風速を検出する風速センサを備えている。そして、前述した摩擦帯電動作後における捕集板２の表面の電位すなわち帯電量が予め設定された基準値以下になった場合に、第１の清掃部１０１に付着した塵埃の第２の清掃部１０６による除去性能が低下したと塵埃除去性能低下判定部１０３が判定する。 In the eighth example, the deterioration of the dust removing performance of the dust adhering to the first cleaning unit 101 by the second cleaning unit 106 is reduced based on the amount of charge on the surface of the collecting plate 2 after the triboelectric charging operation described above. The removal performance deterioration determination unit 103 determines. When dust adhering to the brush 3 which is the second cleaning portion 106 accumulates, the brush 3 cannot sufficiently rub the surface of the collection plate 2. Therefore, the amount of charge on the surface of the collecting plate 2 after the above-mentioned triboelectric charging operation is lower than in the normal state. In this example, the dust removal performance deterioration determination unit 103 includes, for example, a surface potential sensor that detects the potential on the surface of the collection plate 2. The air volume sensor for detecting the air volume at the discharge port 14 of the housing 15 or the wind speed sensor for detecting the wind speed is provided. Then, when the potential on the surface of the collecting plate 2 after the triboelectric charging operation, that is, the amount of charge becomes equal to or less than a preset reference value, the second cleaning unit for dust adhering to the first cleaning unit 101 The dust removal performance deterioration determination unit 103 determines that the removal performance by 106 has deteriorated.
　回転駆動部１０２は、第１の清掃部１０１に付着した塵埃の第２の清掃部１０６による除去性能が低下したと塵埃除去性能低下判定部１０３が判定した場合に、前述の反転動作を行わせる。このようにすることで、第１の清掃部１０１に付着した塵埃の第２の清掃部１０６による除去性能が低下した場合に、前述の反転動作を行って第２の清掃部１０６に付着した塵埃を脱落させ、第２の清掃部１０６により第１の清掃部１０１に付着した塵埃を除去する性能を復活させることができる。 When the dust removal performance deterioration determination unit 103 determines that the removal performance of the dust adhering to the first cleaning unit 101 by the second cleaning unit 106 has deteriorated, the rotation drive unit 102 causes the above-mentioned reversal operation. .. By doing so, when the removal performance of the dust adhering to the first cleaning unit 101 by the second cleaning unit 106 deteriorates, the above-mentioned reversing operation is performed to perform the dust adhering to the second cleaning unit 106. Can be removed, and the performance of removing dust adhering to the first cleaning unit 101 by the second cleaning unit 106 can be restored.
　報知部１０５は、集塵装置の使用者、保守作業者、管理者等に集塵装置の状態等を報知するものである。この実施の形態においては、報知部１０５は、回転駆動部１０２が前述の反転動作を行わせた後も、第２の清掃部１０６による第１の清掃部１０１に付着した塵埃の除去性能が低下したと塵埃除去性能低下判定部１０３が判定した場合に報知する。このようにすることで、反転動作によっても第２の清掃部１０６に付着した塵埃を除去しきれずに塵埃除去性能を回復できなかったことを報知し、第２の清掃部１０６の清掃、交換等のメンテナンスを促すことができる。 The notification unit 105 notifies the user, maintenance worker, manager, etc. of the dust collector of the status of the dust collector. In this embodiment, the notification unit 105 has a reduced performance of removing dust adhering to the first cleaning unit 101 by the second cleaning unit 106 even after the rotation driving unit 102 performs the above-mentioned reversing operation. When the dust removal performance deterioration determination unit 103 determines that this has been done, it notifies the user. By doing so, it is notified that the dust removal performance could not be recovered because the dust adhering to the second cleaning unit 106 could not be completely removed even by the reversing operation, and the second cleaning unit 106 was cleaned, replaced, etc. Maintenance can be promoted.
　報知部１０５は、ＬＥＤ等のランプ、スピーカ及び液晶画面等の少なくともいずれかを備えている。そして、報知部１０５は、例えば、ＬＥＤ等のランプを点灯・点滅させたり、スピーカから音を鳴動させたり、液晶画面に表示を行ったりして報知を行う。なお、使用者等が所持するスマートフォン、ＰＣ等の端末装置にインストールされた専用アプリケーション、又は、端末装置のブラウザで実行するＷｅｂアプリケーション等により報知部１０５を構成してもよい。 The notification unit 105 includes at least one of a lamp such as an LED, a speaker, and a liquid crystal screen. Then, the notification unit 105 performs notification by, for example, turning on / blinking a lamp such as an LED, making a sound from a speaker, or displaying on a liquid crystal screen. The notification unit 105 may be configured by a dedicated application installed in a terminal device such as a smartphone or a PC owned by a user or the like, or a Web application executed by a browser of the terminal device.
　回転駆動部１０２は、前述の反転動作において第１の清掃部１０１を当該反転動作の前よりも速く回転させてもよい。このようにすることで、より短時間で前述の反転動作を行って第２の清掃部１０６に付着した塵埃を除去できる。 The rotation drive unit 102 may rotate the first cleaning unit 101 in the above-mentioned reversing operation faster than before the reversing operation. By doing so, the above-mentioned reversing operation can be performed in a shorter time to remove the dust adhering to the second cleaning unit 106.
　前述したように、第２の清掃部１０６であるブラシ３は接地されている。この接地は、特に前述した反転動作において、第２の清掃部１０６であるブラシ３の帯電を取り除く除電部として働く。回転する捕集板２にブラシ３が接触することで摩擦によりブラシ３が帯電する。ブラシ３が帯電すると、ブラシ３に付着した塵埃が静電力によりブラシ３から離脱しづらくなる。そこで、除電部を備えることで、第２の清掃部１０６であるブラシ３を除電して、前述した反転動作においてブラシ３に付着した塵埃を除去しやすくできる。 As described above, the brush 3 which is the second cleaning unit 106 is grounded. This grounding works as a static elimination unit that removes the charge of the brush 3 which is the second cleaning unit 106, particularly in the above-mentioned reversal operation. When the brush 3 comes into contact with the rotating collecting plate 2, the brush 3 is charged by friction. When the brush 3 is charged, the dust adhering to the brush 3 becomes difficult to separate from the brush 3 due to the electrostatic force. Therefore, by providing the static elimination unit, the brush 3 which is the second cleaning unit 106 can be statically eliminated, and the dust adhering to the brush 3 can be easily removed in the above-mentioned reversing operation.
　なお、第１のシャフト８を介して捕集板２を接地してもよい。この際、意図せずに捕集板２が除電されてしまうことを避けるため、捕集板２を接地するか否かを切り替えるスイッチを設けるとよい。ブラシ３についても同様に、ブラシ３を接地するか否かを切り替えるスイッチを設けてもよい。捕集板２とブラシ３の接地を切り替えることで、状況、動作に応じて、捕集板２、ブラシ３を帯電させて静電力による塵埃吸着作用を優先するのか、捕集板２、ブラシ３を除電して、これらから塵埃を除去しやすくすることを優先するのかを選択できる。また、特に前述した摩擦帯電動作中においては、捕集板２及びブラシ３を接地しないようにするとよい。摩擦帯電動作中に捕集板２及びブラシ３を接地すると、捕集板２とブラシ３との間に電位差が形成され難くなるためである。 The collection plate 2 may be grounded via the first shaft 8. At this time, in order to prevent the collection plate 2 from being unintentionally discharged, it is preferable to provide a switch for switching whether or not the collection plate 2 is grounded. Similarly, the brush 3 may be provided with a switch for switching whether or not the brush 3 is grounded. By switching the grounding of the collection plate 2 and the brush 3, depending on the situation and operation, whether the collection plate 2 and the brush 3 are charged and the dust adsorption action by the electrostatic force is prioritized, the collection plate 2 and the brush 3 You can choose whether to prioritize removing static electricity from these to make it easier to remove dust. Further, it is preferable that the collection plate 2 and the brush 3 are not grounded, particularly during the triboelectric charging operation described above. This is because if the collecting plate 2 and the brush 3 are grounded during the triboelectric charging operation, it becomes difficult for a potential difference to be formed between the collecting plate 2 and the brush 3.
　次に、以上のように構成された集塵装置の動作例について、図５のフロー図を参照しながら説明する。まず、ステップＳ１１において、集塵装置本体１の集塵動作を開始すると、回転駆動部１０２であるモーター６及び駆動制御部７は、第１の清掃部１０１である捕集板２を正回転させる、すなわち、第１の方向に回転させる。 Next, an operation example of the dust collector configured as described above will be described with reference to the flow chart of FIG. First, in step S11, when the dust collection operation of the dust collector main body 1 is started, the motor 6 and the drive control unit 7 which are the rotation drive units 102 rotate the collection plate 2 which is the first cleaning unit 101 in the forward direction. That is, it is rotated in the first direction.
　続くステップＳ１２において、回転駆動部１０２は、塵埃除去性能低下判定部１０３により検出された第２の清掃部１０６（ブラシ３）に付着している塵埃の量が、前述の基準量以上であるか否かを確認する。塵埃の量が基準量以上の場合、処理はステップＳ１３へと進む。 In the subsequent step S12, whether the amount of dust adhering to the second cleaning unit 106 (brush 3) detected by the dust removal performance deterioration determination unit 103 is equal to or greater than the above-mentioned reference amount. Check if it is not. If the amount of dust is equal to or greater than the reference amount, the process proceeds to step S13.
　ステップＳ１３においては、回転駆動部１０２は前述の反転動作を行わせる。つまり、回転駆動部１０２は、第１の清掃部１０１である捕集板２を逆回転させる、すなわち、第２の方向に回転させる。続くステップＳ１４において、回転駆動部１０２は前述の反転動作を終了させ、第１の清掃部１０１を正回転すなわち第１の方向への回転に戻す。ステップＳ１４の後、処理はステップＳ１２へと戻る。 In step S13, the rotation drive unit 102 causes the above-mentioned reversing operation to be performed. That is, the rotation drive unit 102 reversely rotates the collection plate 2, which is the first cleaning unit 101, that is, rotates in the second direction. In the following step S14, the rotation driving unit 102 ends the above-mentioned reversing operation, and returns the first cleaning unit 101 to forward rotation, that is, rotation in the first direction. After step S14, the process returns to step S12.
　一方、ステップＳ１２で塵埃除去性能低下判定部１０３により検出された塵埃の量が基準量以上でない場合、処理はステップＳ１５へと進む。ステップＳ１５においては、回転駆動部１０２は、ステップＳ１１で集塵動作を開始してからの経過時間が運転終了時間に達したか否かを確認する。集塵動作を開始してから運転終了時間が経過していない場合、運転終了時間が経過するまでステップＳ１５の処理を繰り返す。そして、経過時間が運転終了時間に達したら、処理はステップＳ１６へと進む。 On the other hand, if the amount of dust detected by the dust removal performance deterioration determination unit 103 in step S12 is not equal to or greater than the reference amount, the process proceeds to step S15. In step S15, the rotation drive unit 102 confirms whether or not the elapsed time from the start of the dust collecting operation in step S11 has reached the operation end time. If the operation end time has not elapsed since the start of the dust collection operation, the process of step S15 is repeated until the operation end time elapses. Then, when the elapsed time reaches the operation end time, the process proceeds to step S16.
　ステップＳ１６においては、回転駆動部１０２は前述の反転動作を行わせる。つまり、回転駆動部１０２は、第１の清掃部１０１を逆回転させる、すなわち、第２の方向に回転させる。そして、処理はステップＳ１７へと進み、回転駆動部１０２は第１の清掃部１０１の回転を停止させ、集塵動作を終了させる。ステップＳ１７の処理が完了すると、一連の動作は終了となる。 In step S16, the rotation drive unit 102 causes the above-mentioned reversing operation to be performed. That is, the rotation drive unit 102 rotates the first cleaning unit 101 in the reverse direction, that is, rotates it in the second direction. Then, the process proceeds to step S17, and the rotation driving unit 102 stops the rotation of the first cleaning unit 101 to end the dust collecting operation. When the process of step S17 is completed, the series of operations ends.
　また、前述の反転動作において、回転駆動部１０２は、第１の清掃部１０１の回転方向を複数回反転させてよい。すなわち、回転駆動部１０２は、第１の清掃部１０１の第１の方向への回転と第２の方向への回転を交互に繰り返してもよい。このようにすることで、より効果的に第１の清掃部１０１及び第２の清掃部１０６に付着した塵埃を除去できる。 Further, in the above-mentioned reversing operation, the rotation driving unit 102 may reverse the rotation direction of the first cleaning unit 101 a plurality of times. That is, the rotation drive unit 102 may alternately repeat the rotation of the first cleaning unit 101 in the first direction and the rotation in the second direction. By doing so, it is possible to more effectively remove the dust adhering to the first cleaning unit 101 and the second cleaning unit 106.
実施の形態２．
　図６から図８を参照しながら、この発明の実施の形態２について説明する。図６は集塵装置である電気掃除機の全体構成を模式的に示す図である。そして、図７及び図８は集塵装置である電気掃除機の要部の構成を模式的に示す断面図である。 Embodiment 2.
A second embodiment of the present invention will be described with reference to FIGS. 6 to 8. FIG. 6 is a diagram schematically showing the overall configuration of a vacuum cleaner which is a dust collector. 7 and 8 are cross-sectional views schematically showing the configuration of a main part of the vacuum cleaner which is a dust collector.
　前述した実施の形態１は、集塵装置を空気調和機に搭載したものであった。これに対し、ここで説明する実施の形態２は、集塵装置を電気掃除機に適用したものである。以下、この実施の形態２に係る集塵装置について、実施の形態１との相違点を中心に説明する。説明を省略した構成については実施の形態１と基本的に同様である。 In the first embodiment described above, the dust collector is mounted on the air conditioner. On the other hand, in the second embodiment described here, the dust collector is applied to the vacuum cleaner. Hereinafter, the dust collector according to the second embodiment will be described focusing on the differences from the first embodiment. The configuration in which the description is omitted is basically the same as that in the first embodiment.
　この実施の形態に係る集塵装置を適用した電気掃除機５１は、図６に示すように、掃除機本体６０、延長管７０及び吸込口体８０を備えている。掃除機本体６０は、ごみを含む空気（含塵空気）からごみを分離し、ごみが取り除かれた空気（清流空気）を排出する（例えば、室内に戻す）ためのものである。掃除機本体６０の内部には、集塵ケース６１及び電動送風機６２が備えられている。集塵ケース６１は、掃除機本体６０へと流入した含塵空気中のごみ（塵埃）を捕捉して集めるためのものである。電動送風機６２は、掃除機本体６０の集塵ケース６１へと含塵空気を吸引するための気流を作り出すためのものである。 As shown in FIG. 6, the electric vacuum cleaner 51 to which the dust collector according to this embodiment is applied includes a vacuum cleaner main body 60, an extension pipe 70, and a suction port 80. The vacuum cleaner main body 60 is for separating dust from air containing dust (dust-containing air) and discharging the air from which the dust has been removed (clear stream air) (for example, returning it to the room). A dust collecting case 61 and an electric blower 62 are provided inside the vacuum cleaner main body 60. The dust collecting case 61 is for catching and collecting dust (dust) in the dust-containing air that has flowed into the vacuum cleaner main body 60. The electric blower 62 is for creating an air flow for sucking dust-containing air into the dust collecting case 61 of the vacuum cleaner main body 60.
　掃除機本体６０の前端部には、ホース５２の一端部が接続されている。このホース５２は、蛇腹等により可撓性を備えた中空筒状の部材からなる。ホース５２の他端部には、延長管７０の一端部が接続されている。延長管７０は、中空筒状の部材からなる。延長管７０は、ここでは例えば直状な中空円筒形を呈する。延長管７０の他端部には、吸込口体８０が着脱可能に接続される。延長管７０には、取っ手５３が取り付けられている。取っ手５３は、電気掃除機５１の使用者が持って操作するためのものである。取っ手５３には、電気掃除機５１の運転を制御するための操作スイッチ（図示せず）等が設けられている。 One end of the hose 52 is connected to the front end of the vacuum cleaner body 60. The hose 52 is made of a hollow tubular member having flexibility due to a bellows or the like. One end of the extension pipe 70 is connected to the other end of the hose 52. The extension tube 70 is made of a hollow tubular member. Here, the extension tube 70 exhibits, for example, a straight hollow cylinder. A suction port body 80 is detachably connected to the other end of the extension pipe 70. A handle 53 is attached to the extension pipe 70. The handle 53 is intended to be held and operated by the user of the vacuum cleaner 51. The handle 53 is provided with an operation switch (not shown) or the like for controlling the operation of the vacuum cleaner 51.
　吸込口体８０の底面には、吸込口８１が形成されている。吸込口８１は、床面等の被清掃面上のごみ、塵埃等を含んだ空気（含塵空気）を吸い込むためのものである。このようにして、吸込口体８０の吸込口８１から掃除機本体６０の集塵ケース６１までが、延長管７０及びホース５２を経由して連通される。そして、吸込口体８０、延長管７０及びホース５２は、含塵空気を掃除機本体６０の外部から内部に流入させるための吸引経路を構成している。 A suction port 81 is formed on the bottom surface of the suction port body 80. The suction port 81 is for sucking air (dust-containing air) containing dust, dust, etc. on the surface to be cleaned such as the floor surface. In this way, the suction port 81 of the suction port body 80 to the dust collecting case 61 of the vacuum cleaner main body 60 are communicated with each other via the extension pipe 70 and the hose 52. The suction port body 80, the extension pipe 70, and the hose 52 form a suction path for allowing dust-containing air to flow from the outside to the inside of the vacuum cleaner main body 60.
　次に、図７及び図８を参照しながら吸込口体８０の構成について説明する。吸込口体８０は、回転ブラシ８２、ブラシ清掃体８４、除電部８５及びブラシモーター８６を備えている。回転ブラシ８２は、被清掃面上の塵埃を掻き取るためのものである。また、回転ブラシ８２は、吸込口体８０の内部に吸い込まれた含塵空気からも塵埃を除去する。回転ブラシ８２は、吸込口体８０の内部に、吸込口８１を臨むようにして配置されている。回転ブラシ８２は、ブラシ回転軸８３を中心にして両方向に回転可能に支持されている。回転ブラシ８２の回転は、吸込口体８０内に収容されたブラシモーター８６により駆動される。 Next, the configuration of the suction port 80 will be described with reference to FIGS. 7 and 8. The suction port body 80 includes a rotating brush 82, a brush cleaning body 84, a static elimination unit 85, and a brush motor 86. The rotary brush 82 is for scraping dust on the surface to be cleaned. The rotating brush 82 also removes dust from the dust-containing air sucked into the suction port body 80. The rotary brush 82 is arranged inside the suction port body 80 so as to face the suction port 81. The rotary brush 82 is rotatably supported in both directions around the brush rotation shaft 83. The rotation of the rotary brush 82 is driven by the brush motor 86 housed in the suction port body 80.
　ブラシ清掃体８４は、吸込口体８０の内部に、回転ブラシ８２と接触して配置されている。ブラシ清掃体８４は、例えば、不織布状、はけ状、スポンジ状又は板状等を呈する部材である。除電部８５は、ブラシ清掃体８４の帯電を取り除くためのものである。除電部８５は、導電性を有する素材からなる。除電部８５は、ブラシ清掃体８４と接触して配置されている。 The brush cleaning body 84 is arranged inside the suction port body 80 in contact with the rotating brush 82. The brush cleaning body 84 is, for example, a member having a non-woven fabric shape, a brush shape, a sponge shape, a plate shape, or the like. The static elimination unit 85 is for removing the charge of the brush cleaning body 84. The static elimination unit 85 is made of a conductive material. The static elimination unit 85 is arranged in contact with the brush cleaning body 84.
　次に、実施の形態１の説明で参照した図４をここでも参照しながら、この実施の形態の集塵装置について説明を続ける。この実施の形態の回転ブラシ８２は、第１の清掃部１０１である。第１の清掃部１０１である回転ブラシ８２は、清掃対象である被清掃面及び含塵空気と接触可能に設けられている。そして、第１の清掃部１０１である回転ブラシ８２は、塵埃を回転ブラシ８２自身に付着させて清掃対象である被清掃面及び含塵空気から塵埃を除去する。 Next, the dust collector of this embodiment will be described with reference to FIG. 4 referred to in the description of the first embodiment. The rotary brush 82 of this embodiment is a first cleaning unit 101. The rotary brush 82, which is the first cleaning unit 101, is provided so as to be in contact with the surface to be cleaned and the dust-containing air to be cleaned. Then, the rotating brush 82, which is the first cleaning unit 101, attaches dust to the rotating brush 82 itself and removes the dust from the surface to be cleaned and the dust-containing air to be cleaned.
　この実施の形態のブラシモーター８６は、回転駆動部１０２である。回転駆動部１０２であるブラシモーター８６は、第１の清掃部１０１である回転ブラシ８２を第１の方向に回転させる。第１の方向は、図７中に矢印で示す方向である。この第１の方向は、被清掃面上で吸込口体８０を前進させる時の回転ブラシ８２の回転方向である。 The brush motor 86 of this embodiment is a rotary drive unit 102. The brush motor 86, which is the rotation drive unit 102, rotates the rotation brush 82, which is the first cleaning unit 101, in the first direction. The first direction is the direction indicated by the arrow in FIG. This first direction is the rotation direction of the rotating brush 82 when the suction port body 80 is advanced on the surface to be cleaned.
　この実施の形態のブラシ清掃体８４は、第２の清掃部１０６である。第２の清掃部１０６であるブラシ清掃体８４は、前述した第１の方向に回転する第１の清掃部１０１（回転ブラシ８２）と接触して設けられている。そして、第２の清掃部１０６であるブラシ清掃体８４は、第１の清掃部１０１である回転ブラシ８２に付着した塵埃を除去する。 The brush cleaning body 84 of this embodiment is a second cleaning unit 106. The brush cleaning body 84, which is the second cleaning unit 106, is provided in contact with the first cleaning unit 101 (rotating brush 82) that rotates in the first direction described above. Then, the brush cleaning body 84, which is the second cleaning unit 106, removes the dust adhering to the rotating brush 82, which is the first cleaning unit 101.
　すなわち、第２の清掃部１０６が第１の清掃部１０１に接続した状態で、回転駆動部１０２が第１の清掃部１０１を第１の方向に回転させることで、清掃対象の塵埃を第１の清掃部１０１に付着させると同時に、第１の清掃部１０１に付着した塵埃が第２の清掃部１０６により除去される。この際、第１の清掃部１０１に付着していた塵埃の一部は、第２の清掃部１０６により払われて脱落する。また、第１の清掃部１０１に付着していた塵埃の他の一部は、第２の清掃部１０６に付着する。 That is, with the second cleaning unit 106 connected to the first cleaning unit 101, the rotation driving unit 102 rotates the first cleaning unit 101 in the first direction to remove dust to be cleaned. At the same time as adhering to the cleaning unit 101, the dust adhering to the first cleaning unit 101 is removed by the second cleaning unit 106. At this time, a part of the dust adhering to the first cleaning unit 101 is removed by the second cleaning unit 106 and falls off. Further, the other part of the dust adhering to the first cleaning unit 101 adheres to the second cleaning unit 106.
　回転駆動部１０２であるブラシモーター８６は、電気掃除機５１に反転動作を行わせる。反転動作とは、第１の清掃部１０１と第２の清掃部１０６とが接触した状態で第１の清掃部１０１を第２の方向に回転させて第２の清掃部１０６に付着した塵埃を脱落させる動作である。第２の方向は、図８中に矢印で示す方向である。すなわち、第２の方向は、第１の方向と反対の方向である。 The brush motor 86, which is the rotation drive unit 102, causes the vacuum cleaner 51 to perform a reversing operation. The reversing operation is a state in which the first cleaning unit 101 and the second cleaning unit 106 are in contact with each other, and the first cleaning unit 101 is rotated in the second direction to remove dust adhering to the second cleaning unit 106. It is an action to drop off. The second direction is the direction indicated by the arrow in FIG. That is, the second direction is the direction opposite to the first direction.
　電気掃除機５１が清掃対象から塵埃を除去する集塵動作を開始すると、回転駆動部１０２は第１の清掃部１０１を第１の方向に回転させる。この第１の方向は、前述したように被清掃面上で回転する回転ブラシ８２により吸込口体８０が前進する回転方向である。このため、回転ブラシ８２を第１の方向に回転させることで、使用者は被清掃面上で吸込口体８０を容易に前進させることができる。 When the electric vacuum cleaner 51 starts the dust collecting operation for removing dust from the object to be cleaned, the rotary drive unit 102 rotates the first cleaning unit 101 in the first direction. This first direction is the rotation direction in which the suction port body 80 is advanced by the rotating brush 82 that rotates on the surface to be cleaned as described above. Therefore, by rotating the rotary brush 82 in the first direction, the user can easily advance the suction port body 80 on the surface to be cleaned.
　吸込口体８０には、被清掃面と当該吸込口体８０とが接触しなくなったことを検知する図示しないスイッチが設けられている。回転駆動部１０２は、このスイッチにより被清掃面と当該吸込口体８０とが接触しなくなったことが検知された場合に、第１の清掃部１０１を第２の方向に回転させる反転動作を行わせる（図８）。 The suction port body 80 is provided with a switch (not shown) for detecting that the surface to be cleaned and the suction port body 80 are no longer in contact with each other. When it is detected by this switch that the surface to be cleaned and the suction port body 80 are no longer in contact with each other, the rotation drive unit 102 performs a reversing operation of rotating the first cleaning unit 101 in the second direction. Let it (Fig. 8).
　この実施の形態の電気掃除機５１においては、前述したように、第１の清掃部１０１を第１の方向に回転させることで、清掃対象の塵埃を第１の清掃部１０１に付着させて清掃対象から取り除きつつ、第１の清掃部１０１に付着した塵埃は、第２の清掃部１０６により第１の清掃部１０１から取り除かれる。このため、長時間にわたって第１の清掃部１０１により清掃対象の塵埃を除去できる。一方、第２の清掃部１０６により第１の清掃部１０１から取り除かれた塵埃の一部は、第２の清掃部１０６に付着する。このため、第１の清掃部１０１を第１の方向に回転させる時間が長くなると、第２の清掃部１０６に付着した塵埃が蓄積する。そこで、前述した反転動作を行うことで、第２の清掃部１０６に付着した塵埃を第１の清掃部１０１との摩擦により取り除くことができる。このため、人為的なメンテナンス作業を行わずに、集塵可能な期間を長くすることが可能である。 In the electric vacuum cleaner 51 of this embodiment, as described above, by rotating the first cleaning unit 101 in the first direction, dust to be cleaned is attached to the first cleaning unit 101 for cleaning. The dust adhering to the first cleaning unit 101 while being removed from the target is removed from the first cleaning unit 101 by the second cleaning unit 106. Therefore, the dust to be cleaned can be removed by the first cleaning unit 101 for a long time. On the other hand, a part of the dust removed from the first cleaning unit 101 by the second cleaning unit 106 adheres to the second cleaning unit 106. Therefore, if the time for rotating the first cleaning unit 101 in the first direction becomes longer, the dust adhering to the second cleaning unit 106 accumulates. Therefore, by performing the reversing operation described above, dust adhering to the second cleaning unit 106 can be removed by friction with the first cleaning unit 101. Therefore, it is possible to extend the period in which dust can be collected without performing artificial maintenance work.
　この実施の形態の集塵ケース６１は、集塵部である。集塵部である集塵ケース６１は、第１の清掃部である回転ブラシ８２及び第２の清掃部１０６であるブラシ清掃体８４から脱落した塵埃を捕集する。第１の清掃部１０１である回転ブラシ８２が第１の方向に回転している時は、主にブラシ清掃体８４により回転ブラシ８２から払い落とされた塵埃が、掃除機本体６０にまで吸引されて集塵ケース６１で捕集される。そして、前述の反転動作中には、第２の清掃部１０６であるブラシ清掃体８４から脱落した塵埃が、掃除機本体６０にまで吸引されて集塵ケース６１で捕集される。 The dust collecting case 61 of this embodiment is a dust collecting unit. The dust collecting case 61, which is a dust collecting unit, collects dust that has fallen off from the rotating brush 82, which is the first cleaning unit, and the brush cleaning body 84, which is the second cleaning unit 106. When the rotating brush 82, which is the first cleaning unit 101, is rotating in the first direction, the dust brushed off from the rotating brush 82 mainly by the brush cleaning body 84 is sucked up to the vacuum cleaner main body 60. It is collected in the dust collection case 61. Then, during the above-mentioned reversing operation, the dust that has fallen off from the brush cleaning body 84, which is the second cleaning unit 106, is sucked up to the vacuum cleaner main body 60 and collected by the dust collecting case 61.
　この実施の形態における清掃対象には、前述したように含塵空気が含まれる。すなわち、この清掃対象は、第１の清掃部１０１である回転ブラシ８２の周囲を流れる流体である。そして、この実施の形態における電動送風機６２は、流れ生成装置１０４である。流れ生成装置１０４である電動送風機６２は、清掃対象である流体の流れを生成する。 The cleaning target in this embodiment includes dust-containing air as described above. That is, the cleaning target is a fluid flowing around the rotating brush 82, which is the first cleaning unit 101. The electric blower 62 in this embodiment is a flow generator 104. The electric blower 62, which is a flow generator 104, generates a flow of a fluid to be cleaned.
　この実施の形態では、流れ生成装置１０４である電動送風機６２は、前述の反転動作中において、清掃対象である流体の流れの速さを当該反転動作前よりも速くする。この実施の形態の電気掃除機５１においては、集塵部である集塵ケース６１は、第２の清掃部１０６であるブラシ清掃体８４に対して、清掃対象の流体すなわち含塵空気の流れの下流側に配置されている。 In this embodiment, the electric blower 62, which is the flow generator 104, makes the flow speed of the fluid to be cleaned faster than before the reversing operation during the reversing operation described above. In the vacuum cleaner 51 of this embodiment, the dust collecting case 61, which is a dust collecting unit, has a flow of the fluid to be cleaned, that is, the flow of dust-containing air, with respect to the brush cleaning body 84, which is the second cleaning unit 106. It is located on the downstream side.
　そこで、前述の反転動作中において、電動送風機６２の回転数を上げることで、ブラシ清掃体８４の周囲の空気流を強くする。このようにすることで、前述の反転動作中においてブラシ清掃体８４（第２の清掃部１０６）から脱落した塵埃を速やかに掃除機本体６０に吸引して、集塵ケース６１（集塵部）で捕集しやすくできる。 Therefore, during the above-mentioned reversing operation, the rotation speed of the electric blower 62 is increased to strengthen the air flow around the brush cleaning body 84. By doing so, the dust that has fallen off from the brush cleaning body 84 (second cleaning unit 106) during the above-mentioned reversing operation is quickly sucked into the vacuum cleaner main body 60, and the dust collecting case 61 (dust collecting unit). Can be easily collected with.
　除電部８５は、特に前述した反転動作において、第２の清掃部１０６であるブラシ清掃体８４の帯電を取り除く。回転する回転ブラシ８２にブラシ清掃体８４が接触することで摩擦によりブラシ清掃体８４が静電気を帯びることがある。ブラシ清掃体８４が帯電すると、ブラシ清掃体８４に付着した塵埃が静電力によりブラシ清掃体８４から離脱しづらくなる。そこで、除電部８５を備えることで、第２の清掃部１０６であるブラシ清掃体８４を除電して、前述した反転動作においてブラシ清掃体８４に付着した塵埃を除去しやすくできる。 The static elimination unit 85 removes the charge of the brush cleaning body 84, which is the second cleaning unit 106, particularly in the above-mentioned reversing operation. When the brush cleaning body 84 comes into contact with the rotating rotating brush 82, the brush cleaning body 84 may be charged with static electricity due to friction. When the brush cleaning body 84 is charged, dust adhering to the brush cleaning body 84 becomes difficult to separate from the brush cleaning body 84 due to electrostatic force. Therefore, by providing the static elimination unit 85, the brush cleaning body 84, which is the second cleaning unit 106, can be statically eliminated, and dust adhering to the brush cleaning body 84 can be easily removed in the above-described reversing operation.
