In the case of this configuration, the dust collector is located on the placement part, and the main body suction port is located at the front end of the placement part. Therefore, when the suction port of the dust collection device is provided at the rear part of the dust collection device The main body side air passage portion that communicates the main body suction port and the suction port of the dust collector is bent upward in an L shape. Such an L-shaped main body side air passage portion needs to be separately provided with a configuration for removing dust at the corners so that the bent corners are not clogged with dust, which complicates the configuration and increases costs.

Then, vibration (impact) is applied by flipping the pleated filter 111 by sliding the dust removing body 127, and dust (fine dust) adhering to the pleated filter 111 is dropped and removed.
　蓋部64は、有蓋円筒状に形成され、フィルタ体63の上方を覆っている。また、この蓋部64の上部には、集塵装置27を本体ケース26から取り外すための把持部145が形成されている。さらに、この蓋部64の後部には、排気口146が開口されている。また、この蓋部64の後部の左右方向の中央部の上部(排気口146の上方)には、係止クランプ42が上方から係合される係合受部148が凹設されている。そして、この蓋部64は、フィルタ体63の上部との間に、このフィルタ体63の上流側(分離部91)と排気口146とを連通する風路149を区画している。 The lid portion 64 is formed in a covered cylindrical shape and covers the upper side of the filter body 63. In addition, a grip portion 145 for removing the dust collector 27 from the main body case 26 is formed on the upper portion of the lid portion 64. Further, an exhaust port 146 is opened at the rear portion of the lid portion 64. In addition, an engagement receiving portion 148 to which the locking clamp 42 is engaged from above is recessed at the upper portion (above the exhaust port 146) of the rear portion of the lid portion 64 in the left-right direction. The lid portion 64 defines an air passage 149 that communicates the upstream side (separation portion 91) of the filter body 63 and the exhaust port 146 with the upper portion of the filter body 63.
　排気口146は、風路149を通過した空気が集塵装置27の外部へと排出されるもので、例えば左右方向に長手状、すなわち横長に形成されている。この排気口146の周縁部には、集塵装置27を本体ケース26に装着した状態で後部シール部材48に対して圧接されて排気口146と吸気開口部41とを気密に接続するための後部圧接部164が形成されている。さらに、この排気口146には、補強用のリブ165が上下方向に沿って形成され、これらリブ165が左右方向に互いに離間されて配置されている。 The exhaust port 146 is for exhausting the air that has passed through the air passage 149 to the outside of the dust collector 27, and is formed, for example, in the longitudinal direction, that is, in the lateral direction. A rear portion for airtightly connecting the exhaust port 146 and the intake opening 41 by being pressed against the rear seal member 48 in a state where the dust collector 27 is attached to the main body case 26 at the peripheral portion of the exhaust port 146 A pressure contact portion 164 is formed. Further, reinforcing ribs 165 are formed in the exhaust port 146 along the vertical direction, and these ribs 165 are arranged apart from each other in the horizontal direction.
　クランプ65は、取手69の上端部に取り付けられている。そして、このクランプ65は、フィルタ体63をカップ部61に対して着脱可能に係止するとともに、蓋部64をフィルタ体63(およびカップ部61)に対して周方向に回り止めしており、例えば取手69を把持した手の親指により上方から押動操作可能となっている。 The clamp 65 is attached to the upper end of the handle 69. The clamp 65 removably locks the filter body 63 with respect to the cup portion 61, and the lid portion 64 is prevented from rotating in the circumferential direction with respect to the filter body 63 (and the cup portion 61). For example, a push operation can be performed from above with the thumb of the hand holding the handle 69.
　次に、上記一実施形態による掃除動作を説明する。 Next, the cleaning operation according to the above embodiment will be described.
　掃除を開始する際には、まず、カップ部61に対して内筒部62、フィルタ体63および蓋部64をそれぞれ取り付けて一体的に組み立てる。このとき、カップ部61に内挿した内筒部62をカップ部61に対して周方向に回り止めした状態で位置決め固定して受け部シール部材95の外周側をカップ部61(カップ部本体67)の内周面に圧接し、次いでフィルタ体63を内筒部62に取り付けた後、フィルタ体63を覆って蓋部64を被せ、蓋部64を周方向に回動させてクランプ65により回り止め固定する。 When starting cleaning, first, the inner cylinder part 62, the filter body 63, and the lid part 64 are respectively attached to the cup part 61 and assembled integrally. At this time, the inner cylinder part 62 inserted in the cup part 61 is positioned and fixed in a state in which the inner cylinder part 62 is prevented from rotating in the circumferential direction with respect to the cup part 61, and the outer peripheral side of the receiving part seal member 95 is connected to the cup part 61 (cup part main body 67 ), And then the filter body 63 is attached to the inner cylinder portion 62. Then, the filter body 63 is covered and covered with the lid portion 64. The lid portion 64 is rotated in the circumferential direction and rotated by the clamp 65. Stop and fix.
　次いで、この集塵装置27を本体ケース26に装着する。すなわち、集塵装置27の前側下部を突出受部32の前端部に当接させながら、係止突部77を本体ケース26側の位置決め凹部43に位置合わせしつつ挿入するように集塵装置27の上側を後方に回動させると、係止クランプ42が集塵装置27の係合受部148に上方から係合して、集塵装置27が本体ケース26に固定される。この結果、吸込部68の連通口81の周縁の圧接部82が接続口55の周縁の下部シール部材56に上方から圧接されて吸込部68(連通口81)と接続口55とが気密に接続されるとともに、排気口146の周縁の後部圧接部164が吸気開口部41の周縁の後部シール部材48に前方から圧接されて排気口146と吸気開口部41とが気密に接続される。なお、集塵装置27が本体ケース26に既に装着された状態である場合には、これらの操作は不要である。 Next, the dust collector 27 is attached to the main body case 26. That is, the dust collector 27 is inserted so that the locking protrusion 77 is inserted into the positioning recess 43 on the main body case 26 side while the front lower portion of the dust collector 27 is brought into contact with the front end portion of the protrusion receiving portion 32. When the upper side is rotated rearward, the locking clamp 42 engages with the engagement receiving portion 148 of the dust collector 27 from above, and the dust collector 27 is fixed to the main body case 26. As a result, the pressure contact portion 82 at the periphery of the communication port 81 of the suction portion 68 is pressed from above to the lower seal member 56 at the periphery of the connection port 55, and the suction portion 68 (communication port 81) and the connection port 55 are connected in an airtight manner. At the same time, the rear pressure contact portion 164 at the periphery of the exhaust port 146 is pressed against the rear seal member 48 at the periphery of the intake opening 41 from the front, and the exhaust port 146 and the intake opening 41 are connected in an airtight manner. Note that when the dust collector 27 is already attached to the main body case 26, these operations are not necessary.
　この状態で、掃除機本体13(本体ケース26)の本体吸込口54に管部12を接続する。具体的に、管部12は、接続管部15を本体吸込口54に挿入接続するとともに、必要に応じて、手元操作部17の先端側に延長管18および床ブラシ19を順次接続する。この状態で、手元操作部17の設定ボタン22が掃除機本体13(本体ケース26)内の制御回路部37などと電気的に接続される。なお、管部12が掃除機本体13に既に接続された状態である場合には、これらの操作は不要である。 In this state, the pipe portion 12 is connected to the main body suction port 54 of the cleaner body 13 (main body case 26). Specifically, the pipe part 12 inserts and connects the connection pipe part 15 to the main body suction port 54, and sequentially connects the extension pipe 18 and the floor brush 19 to the distal end side of the hand operation part 17 as necessary. In this state, the setting button 22 of the hand operation unit 17 is electrically connected to the control circuit unit 37 and the like in the cleaner body 13 (main body case 26). In addition, when the pipe part 12 is already connected to the cleaner body 13, these operations are unnecessary.
　そして、使用者は、コード導出口45から電源コード38を引き出して壁面などのコンセントに接続した後、手元把持部21を把持し、所望の設定ボタン22を操作することにより、電動送風機36の動作モードを設定する。制御回路部37は、この設定された動作モードに対応して電動送風機36の入力を制御し、電動送風機36を設定された動作モードで起動する。 Then, after the user pulls out the power cord 38 from the cord outlet 45 and connects it to an outlet such as a wall surface, the user grips the hand grip 21 and operates the desired setting button 22 to operate the electric blower 36. Set the mode. The control circuit unit 37 controls the input of the electric blower 36 corresponding to the set operation mode, and starts the electric blower 36 in the set operation mode.
　この電動送風機36の起動により生じた負圧は、吸気開口部41、排気口146、プリーツフィルタ111、分離部91、吸込口72、吸込部68、接続口55(連通口81)、本体側風路部53および本体吸込口54を介して、管部12へと作用する。 The negative pressure generated by the activation of the electric blower 36 is the intake opening 41, the exhaust port 146, the pleated filter 111, the separation unit 91, the suction port 72, the suction unit 68, the connection port 55 (communication port 81), the body side wind It acts on the pipe portion 12 via the passage portion 53 and the main body suction port.
　そして、使用者は、この負圧の作用により、床ブラシ19、延長管18、あるいは手元操作部17の先端側から空気とともに塵埃を吸い込む。 And the user sucks dust together with air from the floor brush 19, the extension pipe 18, or the front end side of the hand operation section 17 by the action of this negative pressure.
　この塵埃を含む空気、すなわち含塵空気は、管部12から本体吸込口54、本体側風路部53および接続口55(連通口81)を経由して吸込部68から吸込口72へと導かれ、この吸込口72からカップ部61内へと吸い込まれる。 The dust-containing air, that is, the dust-containing air, is introduced from the pipe portion 12 through the main body suction port 54, the main body side air passage portion 53, and the connection port 55 (communication port 81) from the suction portion 68 to the suction port 72. Then, it is sucked into the cup part 61 from the suction port 72.
　このカップ部61内の分離部91において、含塵空気はカップ部61の内周面に沿って内筒部本体88の外周を旋回することで、この含塵空気中の特に粗塵が遠心分離され、カップ部61の内周面に沿って落下して塵埃溜め部92に溜められる。なお、塵埃溜め部92に溜められた塵埃(粗塵)は、シェード部89へと含塵空気の流れの一部によって運ばれ、シェード部89の圧縮用開口108を含塵空気が通過することにより圧縮フィルタ109によってシェード部89内で圧縮される。 In the separation part 91 in the cup part 61, the dust-containing air turns around the outer periphery of the inner cylinder part body 88 along the inner peripheral surface of the cup part 61, so that particularly coarse dust in the dust-containing air is centrifuged. Then, it falls along the inner peripheral surface of the cup portion 61 and is collected in the dust reservoir 92. The dust (coarse dust) collected in the dust reservoir 92 is carried to the shade portion 89 by a part of the flow of the dust-containing air, and the dust-containing air passes through the compression opening 108 of the shade portion 89. Thus, compression is performed in the shade unit 89 by the compression filter 109.
　粗塵が分離された含塵空気は、内筒部本体88の開口101を通過する際に分離フィルタ102により濾過される。さらに、この分離フィルタ102を通過した含塵空気は、底面部103に沿って下流側である上側へと整流されつつフィルタ体63へと運ばれる。そして、この含塵空気は、このフィルタ体63のプリーツフィルタ111を通過することで、このプリーツフィルタ111により、分離部91で分離した塵埃(粗塵)よりも小さい塵埃(細塵)が表面集塵される。 The dust-containing air from which the coarse dust has been separated is filtered by the separation filter 102 when passing through the opening 101 of the inner cylinder main body 88. Further, the dust-containing air that has passed through the separation filter 102 is conveyed to the filter body 63 while being rectified along the bottom surface 103 to the upper side, which is the downstream side. The dust-containing air passes through the pleated filter 111 of the filter body 63, so that dust (fine dust) smaller than the dust (coarse dust) separated by the separation unit 91 is collected on the surface by the pleated filter 111. Be dusted.
　この後、プリーツフィルタ111を通過した空気は、このプリーツフィルタ111の間、および、プリーツフィルタ111の上部と蓋部64との間の風路149を通過し、排気口146から集塵装置27の外部へと流出して、この排気口146と気密に接続された吸気開口部41へと吸い込まれる。 Thereafter, the air that has passed through the pleat filter 111 passes through the air path 149 between the pleat filter 111 and between the upper portion of the pleat filter 111 and the lid portion 64, and is passed through the exhaust port 146 to the dust collector 27. It flows out to the outside and is sucked into the intake opening 41 that is airtightly connected to the exhaust port 146.
　そして、吸気開口部41(吸気フィルタ49)を通過した空気は、ダクト部50を介して電動送風機36へと吸い込まれ、この電動送風機36の内部を冷却しつつ通過して排気風となり、電動送風機36から排気孔44を介して本体ケース26の外部へと排気される。 Then, the air that has passed through the intake opening 41 (intake filter 49) is sucked into the electric blower 36 through the duct portion 50, passes through while cooling the inside of the electric blower 36 to become exhaust air, and the electric blower The air is exhausted from 36 to the outside of the main body case 26 through the exhaust hole 44.
　掃除が終了すると、使用者が所定の設定ボタン22を操作することで、制御回路部37が電動送風機36の入力を低下させて電動送風機36を停止させる。 When the cleaning is completed, the user operates the predetermined setting button 22 so that the control circuit unit 37 decreases the input of the electric blower 36 and stops the electric blower 36.
　また、フィルタ体63のプリーツフィルタ111に付着した塵埃(細塵)を廃棄する(プリーツフィルタ111をメンテナンスする)場合には、係止クランプ42を操作して本体ケース26から集塵装置27を取り外し、蓋部64を周方向に回動させてフィルタ体63から取り外し、除塵機構113の除塵体127をスライドさせると、プリーツフィルタ111に断続的に振動(衝撃)が付与されて、このプリーツフィルタ111に付着した塵埃(細塵)が落下除去される。そして、このフィルタ体63をカップ部61から取り外して、カップ部61をごみ箱などの廃棄位置へ持って行き、塵埃を廃棄する。なお、フィルタ体63の取り外しにより露出した内筒部62については、受け部87の中央部に位置する連通開口部96から分離フィルタ102の内側などに付着した塵埃を除去したり、受け部87上に付着した塵埃を除去したりすることが可能である。 When discarding dust (fine dust) adhering to the pleated filter 111 of the filter body 63 (maintaining the pleated filter 111), the locking clamp 42 is operated to remove the dust collector 27 from the main body case 26. When the lid 64 is rotated in the circumferential direction to be removed from the filter body 63 and the dust removing body 127 of the dust removing mechanism 113 is slid, vibration (impact) is intermittently applied to the pleated filter 111, and the pleated filter 111 Dust (fine dust) adhering to is dropped and removed. Then, the filter body 63 is removed from the cup portion 61, and the cup portion 61 is taken to a disposal position such as a trash can to discard dust. For the inner cylindrical portion 62 exposed by removing the filter body 63, dust attached to the inner side of the separation filter 102 or the like is removed from the communication opening 96 located at the center of the receiving portion 87, or on the receiving portion 87. It is possible to remove dust adhering to the surface.
　さらに、集塵装置27内に一定量の塵埃が溜まった場合には、使用者は、係止クランプ42を操作して本体ケース26から取り外した集塵装置27において、クランプ65を操作してフィルタ体63および内筒部62の係止を解除してカップ部61からこれらフィルタ体63および内筒部62を蓋部64と一体的に取り外し、取手69を把持したカップ部61をごみ箱などの廃棄位置へと運んだ後、上側を下方へと傾けるようにひっくり返すことで、塵埃溜め部92に圧縮された状態で溜まった塵埃(粗塵)が塵埃排出口71から廃棄される。 Further, when a certain amount of dust accumulates in the dust collector 27, the user operates the clamp 65 in the dust collector 27 removed from the main body case 26 by operating the locking clamp 42, and filters it. The body 63 and the inner cylinder 62 are unlocked, the filter body 63 and the inner cylinder 62 are removed from the cup 61 integrally with the lid 64, and the cup 61 holding the handle 69 is disposed of as a trash can. After being carried to the position, the upper side is turned over so that the upper side is inclined downward, so that the dust (coarse dust) accumulated in the dust reservoir 92 is discarded from the dust outlet 71.
　以上説明した一実施形態によれば、本体ケース26の集塵装置27を載置する突出受部32に、管部12が接続される本体吸込口54を有する本体側風路部53を設けることで、管部12を集塵装置27の下方に配置することができ、この管部12により集塵装置27の視認性を低下させることがない。したがって、集塵装置27のカップ部61(カップ部本体67)内を旋回する塵埃の遠心分離の様子を掃除中に使用者が目視でき、掃除感を向上できるとともに、カップ部61(カップ部本体67)内に溜まった塵埃量を容易に目視確認できるので、塵埃を廃棄すべきタイミングを容易に知ることができ、使い勝手がよい。 According to the embodiment described above, the main body side air passage portion 53 having the main body suction port 54 to which the pipe portion 12 is connected is provided in the protrusion receiving portion 32 on which the dust collecting device 27 of the main body case 26 is placed. Thus, the pipe portion 12 can be disposed below the dust collector 27, and the visibility of the dust collector 27 is not reduced by the pipe portion 12. Therefore, the user can visually check the state of the centrifugal separation of the dust swirling in the cup portion 61 (cup portion main body 67) of the dust collector 27, and the cleaning feeling can be improved, and the cup portion 61 (cup portion main body) can be improved. 67) Since the amount of dust accumulated in it can be easily visually confirmed, it is easy to know when to dispose of dust and it is easy to use.
　また、集塵装置27に、下方に延びる吸込部68を設け、本体側風路部53に、この吸込部68と接続される接続口55を設けることで、本体側風路部53をＬ字状に屈曲させた形状とする必要がなく、本体側風路部53内への塵埃の詰まりを簡単な構成で確実に抑制できる。したがって、本体側風路部53内の塵埃の詰まりを解消するための窓部などの構成を別途設ける必要がなく、メンテナンス性が良好であるだけでなく、構成を簡略化でき、低コスト化および軽量化、小型化などが可能になる。 In addition, the dust collector 27 is provided with a suction portion 68 extending downward, and the main body side air passage portion 53 is provided with a connection port 55 connected to the suction portion 68, thereby making the main body side air passage portion 53 an L-shape. It is not necessary to have a bent shape, and clogging of dust into the main body side air passage portion 53 can be reliably suppressed with a simple configuration. Therefore, there is no need to separately provide a structure such as a window part for eliminating the clogging of dust in the main body side air passage part 53, not only good maintainability, but also the structure can be simplified, the cost can be reduced, and It is possible to reduce weight and size.
　しかも、集塵装置27の吸込部68(連通口81)と本体ケース26の接続口55との接続は、集塵装置27の自重が加わる上下方向となるため、集塵装置27の自重によって吸込部68の下端部(連通口81の周縁)の圧接部82が接続口55の周縁の下部シール部材56に対して押し付けられることとなり、これらの接続のシール性がより向上する。 Moreover, since the connection between the suction part 68 (communication port 81) of the dust collector 27 and the connection port 55 of the main body case 26 is in the vertical direction to which the weight of the dust collector 27 is applied, suction is performed by the weight of the dust collector 27. The press contact portion 82 at the lower end portion of the portion 68 (periphery of the communication port 81) is pressed against the lower seal member 56 at the periphery of the connection port 55, and the sealing performance of these connections is further improved.
　さらに、突出受部32は、接続口55が位置する後部へと下方に傾斜している、換言すれば、突出受部32において接続口55が最も低い位置に設けられているため、仮に集塵装置27を取り外したときなどに集塵装置27(吸込部68)から突出受部32上に塵埃がこぼれたとしても、その塵埃を接続口55へと容易に落とし込むことができる。そして、落とし込んだ塵埃は、集塵装置27を本体ケース26に再装着して起動させた際に、集塵装置27へと吸い込んで捕集できる。 Further, the protrusion receiving portion 32 is inclined downward toward the rear portion where the connection port 55 is located. In other words, since the connection port 55 is provided at the lowest position in the protrusion receiving portion 32, the dust collection is temporarily performed. Even if dust is spilled from the dust collecting device 27 (suction portion 68) onto the protruding receiving portion 32 when the device 27 is removed, the dust can be easily dropped into the connection port 55. The dropped dust can be sucked into the dust collector 27 and collected when the dust collector 27 is reattached to the main body case 26 and activated.
　なお、上記一実施形態において、集塵装置27の内部構成は任意に設定でき、例えば多段の遠心分離部を備える構成、あるいは単数、または複数の濾過フィルタを備えるのみの構成などとしてもよい。 In the above-described embodiment, the internal configuration of the dust collector 27 can be arbitrarily set. For example, a configuration including a multistage centrifuge unit or a configuration including only one or a plurality of filtration filters may be used.
　また、電源部としては、コードリール装置に代えて、例えば二次電池などの電池を内蔵してもよい。 Further, as the power supply unit, a battery such as a secondary battery may be incorporated instead of the cord reel device.
　本発明の一実施形態を説明したが、この実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。この新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。この実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。 Although one embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention.
