Specifically, the operation unit 24 includes a stop switch 24 a associated with an operation stop operation of the electric blower 7 and an activation switch 24 b associated with an operation start operation of the electric blower 7. The stop switch 24 a and the start switch 24 b are electrically connected to the main body control unit 9. A user of the vacuum cleaner 1 can alternatively select an operation mode of the electric blower 7 by operating the operation unit 24. The start switch 24b also functions as an operation mode selection switch during operation of the electric blower 7. In this case, every time the operation signal is received from the start switch 24b, the main body control unit 9 switches the operation mode in the order of strong → medium → weak → strong →. Note that the operation unit 24 may individually include a weak operation switch (not shown), a medium operation switch (not shown), and a strong operation switch (not shown) instead of the start switch 24b.

延長管２５は、伸縮可能な細長略円筒状の管である。延長管２５は、複数の筒状体を重ね合わせたテレスコピック構造を有する。延長管２５の一方の端部（ここでは、後方の端部）と手元操作管２２の他方の端部（ここでは、前方の端部）とは着脱自在な継手構造を備える。延長管２５は、手元操作管２２、集塵ホース２１および接続管１９を通じて塵埃分離集塵装置８に流体的に接続される。   The extension tube 25 is an elongated substantially cylindrical tube that can be expanded and contracted. The extension tube 25 has a telescopic structure in which a plurality of cylindrical bodies are overlapped. One end portion (here, the rear end portion) of the extension tube 25 and the other end portion (here, the front end portion) of the hand operation tube 22 have a detachable joint structure. The extension pipe 25 is fluidly connected to the dust separating and collecting apparatus 8 through the hand operating pipe 22, the dust collecting hose 21 and the connecting pipe 19.

吸込口体２６は、木床やカーペットなどの被掃除面上を走行自在あるいは滑走自在な構造を有するとともに、走行状態または滑走状態において被掃除面に対向する底面に吸込口２８を有する。また、吸込口体２６は、吸込口２８に配置される回転自在な回転清掃体２９と、回転清掃体２９を駆動させる電動機３１と、を備える。吸込口体２６の一方の端部（ここでは、後方の端部）と延長管２５の他方の端部（ここでは、前方の端部）とは着脱自在な継手構造を備える。吸込口体２６は、延長管２５、手元操作管２２、集塵ホース２１および接続管１９を通じて塵埃分離集塵装置８に流体的に接続される。   The suction port body 26 has a structure capable of running or sliding on a surface to be cleaned such as a wooden floor or a carpet, and has a suction port 28 on the bottom surface facing the surface to be cleaned in the running state or the sliding state. The suction port body 26 includes a rotatable rotary cleaning body 29 disposed in the suction port 28 and an electric motor 31 that drives the rotary cleaning body 29. One end portion (here, the rear end portion) of the suction port body 26 and the other end portion (here, the front end portion) of the extension pipe 25 have a detachable joint structure. The suction port body 26 is fluidly connected to the dust separating and collecting device 8 through the extension pipe 25, the hand operating pipe 22, the dust collecting hose 21 and the connecting pipe 19.

電気掃除機１は、起動スイッチ２４ｂに対する操作を受け付けると電動送風機７を始動させる。例えば、電気掃除機１は、電動送風機７が停止している状態で起動スイッチ２４ｂに対する操作を受け付けると、先ず電動送風機７を強運転モードで運転し、再び起動スイッチ２４ｂに対する操作を受け付けると電動送風機７を中運転モードで運転し、三度、起動スイッチ２４ｂに対する操作を受け付けると電動送風機７を弱運転モードで運転し、以下同様に繰り返す。強運転モード、中運転モードおよび弱運転モードは、予め設定される複数の運転モードであり、強運転モード、中運転モード、弱運転モードの順に電動送風機７に対する入力値が小さい。始動した電動送風機７は、塵埃分離集塵装置８から空気を排気してその内部を負圧（吸込負圧）にする。   The vacuum cleaner 1 starts the electric blower 7 when the operation with respect to the starting switch 24b is received. For example, when the vacuum cleaner 1 receives an operation on the start switch 24b while the electric blower 7 is stopped, the electric blower first operates the electric blower 7 in the strong operation mode, and receives an operation on the start switch 24b again. 7 is operated in the medium operation mode, and when an operation to the start switch 24b is accepted three times, the electric blower 7 is operated in the weak operation mode, and the same is repeated thereafter. The strong operation mode, the medium operation mode, and the weak operation mode are a plurality of operation modes set in advance, and the input value to the electric blower 7 is small in the order of the strong operation mode, the medium operation mode, and the weak operation mode. The started electric blower 7 exhausts air from the dust separating and collecting device 8 to make the inside thereof a negative pressure (suction negative pressure).

塵埃分離集塵装置８の負圧は、塵埃分離集塵装置８、本体接続口１２、接続管１９、集塵ホース２１、手元操作管２２および延長管２５を通じて吸込口体２６の吸込口２８に作用する。電気掃除機１は、吸込口２８に作用する負圧で被掃除面上の塵埃を空気とともに吸い込んで被掃除面を掃除する。塵埃分離集塵装置８は、電気掃除機１に吸い込まれた含塵空気から塵埃を分離し、蓄積する。他方、塵埃分離集塵装置８は、含塵空気から分離した空気を電動送風機７へ送る。電動送風機７は塵埃分離集塵装置８から吸い込んだ空気を掃除機本体２外へ排気する。   The negative pressure of the dust separation and dust collection device 8 is applied to the suction port 28 of the suction port body 26 through the dust separation and dust collection device 8, the main body connection port 12, the connection tube 19, the dust collection hose 21, the hand operation tube 22 and the extension tube 25. Works. The vacuum cleaner 1 cleans the surface to be cleaned by sucking dust on the surface to be cleaned together with air with a negative pressure acting on the suction port 28. The dust separating and collecting apparatus 8 separates and accumulates dust from the dust-containing air sucked into the vacuum cleaner 1. On the other hand, the dust separating and collecting device 8 sends the air separated from the dust-containing air to the electric blower 7. The electric blower 7 exhausts the air sucked from the dust separating and collecting device 8 to the outside of the cleaner body 2.

次に、塵埃分離集塵装置８を詳細に説明する。   Next, the dust separating and collecting apparatus 8 will be described in detail.

なお、塵埃分離集塵装置８は、掃除機本体２に対して後傾する姿勢で固定されているが、説明を簡単にするために直立させて図示する。   In addition, although the dust separation dust collector 8 is fixed with the attitude | position inclined backward with respect to the cleaner main body 2, in order to demonstrate easily, it is standing and illustrated.

It is fixed. The groove 52 extends in the circumferential direction with respect to the substantially cylindrical dust separating and collecting device 8.

内筒４２は、集塵容器３９内に納められて略同心に配置される。内筒４２は、第二分離部３６に固定される根元部と、集塵容器３９内に延びる自由端部と、を有する。内筒４２は、第一分離部３５と第二分離部３６とを流体的に接続する。内筒４２は、第一分離部３５から空気を流出させる第二開口５３を側壁に有する。メッシュフィルタ５５は第二開口５３に設けられている。内筒４２の側壁は吸気口４６を臨む。   The inner cylinder 42 is accommodated in the dust collecting container 39 and is arranged substantially concentrically. The inner cylinder 42 has a root part fixed to the second separation part 36 and a free end part extending into the dust collecting container 39. The inner cylinder 42 fluidly connects the first separation part 35 and the second separation part 36. The inner cylinder 42 has a second opening 53 through which the air flows out from the first separation part 35 on the side wall. The mesh filter 55 is provided in the second opening 53. The side wall of the inner cylinder 42 faces the air inlet 46.

内筒４２と集塵容器３９とを隔てる空間は、集塵容器３９の吸気口４６から第一分離部３５に流れ込む空気を旋回させて塵埃と空気とを分離する分離室５６である。メッシュフィルタ５５は電動送風機７の始動直後や停止過渡など分離室５６内の旋回流Ｆが十分に発達していない期間において、また旋回流Ｆが発達した後も当然に、第一分離部３５から粗い塵埃が流出することを防ぐ。   The space separating the inner cylinder 42 and the dust collecting container 39 is a separation chamber 56 that swirls the air flowing into the first separating portion 35 from the air inlet 46 of the dust collecting container 39 to separate the dust and air. The mesh filter 55 is naturally removed from the first separation unit 35 during a period when the swirl flow F in the separation chamber 56 is not sufficiently developed, such as immediately after the start of the electric blower 7 or during a stop transition, and also after the swirl flow F has developed. Prevents coarse dust from flowing out.

塵埃捕捉カップ４３は内筒４２の自由端部に設けられる。塵埃捕捉カップ４３は、有底円筒形状を呈し、内筒４２の自由端に連接する底壁と、集塵容器３９の底壁に向かって延びる側壁と、を有する。塵埃捕捉カップ４３は集塵容器３９の底壁に向かって開放される。塵埃捕捉カップ４３の側壁は、隙間を隔てて集塵容器３９の側壁に対向する。塵埃捕捉カップ４３は内筒４２よりも大径であり、内筒４２の自由端に連接して広がる底壁の周縁部分に第三開口５７を有する。   The dust capturing cup 43 is provided at the free end of the inner cylinder 42. The dust trapping cup 43 has a bottomed cylindrical shape, and has a bottom wall connected to the free end of the inner cylinder 42 and a side wall extending toward the bottom wall of the dust collecting container 39. The dust capturing cup 43 is opened toward the bottom wall of the dust collecting container 39. The side wall of the dust catching cup 43 faces the side wall of the dust collecting container 39 with a gap. The dust trapping cup 43 has a diameter larger than that of the inner cylinder 42 and has a third opening 57 at the peripheral portion of the bottom wall that extends in a manner connected to the free end of the inner cylinder 42.

塵埃捕捉カップ４３と集塵容器３９とを隔てる隙間は、第一分離部３５で分離された塵埃が蓄積される集塵部５８である。集塵部５８内の空気は第三開口５７を通じて分離室５６に戻る。   A gap separating the dust capturing cup 43 and the dust collecting container 39 is a dust collecting portion 58 in which the dust separated by the first separating portion 35 is accumulated. The air in the dust collector 58 returns to the separation chamber 56 through the third opening 57.

メッシュフィルタ５９は第三開口５７に設けられている。メッシュフィルタ５９は、集塵室６１に流れ込んだ粗い（糸くずや綿埃などの繊維状の）塵埃が分離室５６へ戻らない程度に目の粗いフィルタで良い。   The mesh filter 59 is provided in the third opening 57. The mesh filter 59 may be a filter that is coarse enough to prevent coarse dust (such as lint and cotton dust) flowing into the dust collecting chamber 61 from returning to the separation chamber 56.

内筒４２および塵埃捕捉カップ４３は、塵埃分離集塵装置８から集塵容器３９を取り外すと、第二分離部３６に随伴して集塵容器３９から抜け出す。   When the dust collecting container 39 is removed from the dust separating and collecting device 8, the inner cylinder 42 and the dust catching cup 43 come out of the dust collecting container 39 along with the second separating portion 36.

第二分離部３６は、塵埃分離集塵装置８の他方の半部の外殻の一部に相当する側壁４１を備える。第二分離部３６は第一分離部３５を通過する細かい塵埃を空気から分離し、電動送風機７に達することを防ぐ。第二分離部３６は集塵容器３９の一方の端部に連結されて開口６２を塞ぐ。第二分離部３６は集塵容器３９の中心線Ｃの延長線上、あるいは第二分離部３６の図心に相当する部分に回避領域６３を隔てて、回避領域６３の周囲を囲む。第二分離部３６は第一分離部３５から流れ込む空気から塵埃を分離して非連結端部側へ空気を流出させる。第二分離部３６は集塵容器３９の中心線Ｃ上に内筒４２を支持する。   The second separator 36 includes a side wall 41 corresponding to a part of the outer shell of the other half of the dust separator / collector 8. The second separation unit 36 separates fine dust that passes through the first separation unit 35 from the air and prevents it from reaching the electric blower 7. The second separation portion 36 is connected to one end portion of the dust collecting container 39 and closes the opening 62. The second separation portion 36 surrounds the avoidance region 63 on the extension line of the center line C of the dust collecting container 39 or at a portion corresponding to the centroid of the second separation portion 36 with the avoidance region 63 therebetween. The second separation unit 36 separates dust from the air flowing in from the first separation unit 35 and causes the air to flow out to the unconnected end portion side. The second separation unit 36 supports the inner cylinder 42 on the center line C of the dust collecting container 39.

第二分離部３６は、第一分離部３５の内筒４２の内側から流入する空気を第二分離部３６の非連結端部側へ導く風路を仕切る案内管６５と、カバー３８の内周面近傍に配置される複数のサイクロン部６６と、塵埃捕捉傘６７と、を備える。   The second separation portion 36 includes a guide pipe 65 that partitions an air passage that guides air flowing from the inner side of the inner cylinder 42 of the first separation portion 35 to the non-connected end portion side of the second separation portion 36, and an inner periphery of the cover 38. A plurality of cyclone portions 66 disposed in the vicinity of the surface and a dust trap umbrella 67 are provided.

案内管６５内の風路（第一分離部３５の内筒４２の内側から流入する空気を第二分離部３６の非連結端部側へ導く風路）は、排気管３７のうち、排気口８３に向かって折れ曲がる部分を、第二分離部３６の図心に相当する部分に納める回避領域６３を兼ねている。つまり、回避領域６３は内筒４２の内側から第二分離部３６へ空気を案内する風路を利用するものである。   An air passage in the guide tube 65 (an air passage that guides air flowing from the inner side of the inner cylinder 42 of the first separation portion 35 to the unconnected end portion side of the second separation portion 36) is an exhaust port of the exhaust pipe 37. It also serves as an avoidance region 63 in which a portion bent toward 83 is accommodated in a portion corresponding to the centroid of the second separation portion 36. That is, the avoidance region 63 uses an air path that guides air from the inside of the inner cylinder 42 to the second separation portion 36.

それぞれのサイクロン部６６は、螺旋流を生じさせる遠心分離方式の円錐台形状内面６８を有する。それぞれのサイクロン部６６は、回避領域６３を囲んで略環状に並ぶ。それぞれのサイクロン部６６は、分離した塵埃を集塵容器３９の開口６２の内縁近傍部に排出する。円錐台形状内面６８は、第二分離部３６の非連結端部側から連結端部側へ向かって縮径している。円錐台形状内面６８の非連結端部側は案内管６５に流体的に接続されている開口６９を有する。また、円錐台形状内面６８の非連結端部側は排気管３７に流体的に接続されている頂部開口７１を有する。円錐台形状内面６８の連結端部側は、集塵容器３９に流体的に接続されて分離した塵埃を排出する開口７２を有する。開口６９からサイクロン部６６に流れ込む空気は開口７２へ向かって渦巻き螺旋流を生じ、空気から細かい塵埃を分離する。塵埃が分離された清浄な空気は、渦巻き螺旋流の中心線（円錐台形状内面６８の中心線）上を流動して頂部開口７１から排気管３７へ流出する。   Each cyclone section 66 has a centrifuge-shaped frustoconical inner surface 68 that generates a spiral flow. Each cyclone part 66 surrounds the avoidance area | region 63, and is located in a substantially cyclic | annular form. Each cyclone portion 66 discharges the separated dust to the vicinity of the inner edge of the opening 62 of the dust collecting container 39. The frustoconical inner surface 68 is reduced in diameter from the non-connecting end portion side of the second separating portion 36 toward the connecting end portion side. The non-connecting end side of the frustoconical inner surface 68 has an opening 69 fluidly connected to the guide tube 65. Further, the non-connected end portion side of the truncated cone-shaped inner surface 68 has a top opening 71 fluidly connected to the exhaust pipe 37. The connecting end portion side of the truncated cone-shaped inner surface 68 has an opening 72 that is fluidly connected to the dust collecting container 39 and discharges the separated dust. The air flowing into the cyclone portion 66 from the opening 69 creates a spiral spiral flow toward the opening 72 and separates fine dust from the air. The clean air from which the dust has been separated flows on the center line of the spiral spiral flow (the center line of the frustoconical inner surface 68) and flows out from the top opening 71 to the exhaust pipe 37.

塵埃捕捉傘６７は、第一分離部３５と第二分離部３６とを区画する隔壁を兼ね、内筒４２の根元に設けられる。塵埃捕捉傘６７は、第二分離部３６よりも小さく、かつ内筒４２よりも大きい外径を呈する。塵埃捕捉傘６７は、サイクロン部６６が捕集する塵埃を集塵容器３９へ導く一方の面７３と、集塵容器３９内へ向かって広がり傾斜する他方の面７５と、を有する。   The dust trap umbrella 67 also serves as a partition that partitions the first separation portion 35 and the second separation portion 36, and is provided at the base of the inner cylinder 42. The dust trap umbrella 67 has an outer diameter that is smaller than the second separation portion 36 and larger than the inner cylinder 42. The dust trap umbrella 67 has one surface 73 that guides the dust collected by the cyclone portion 66 to the dust collection container 39 and the other surface 75 that spreads and inclines into the dust collection container 39.

また、塵埃捕捉傘６７は、集塵容器３９の大径部４７と一般部４８との連接部分に突き当って集塵容器３９を塞ぐ。集塵容器３９の大径部４７および塵埃捕捉傘６７は、サイクロン部６６が排出する塵埃を蓄積する細塵集塵室７６を仕切る。細塵集塵室７６は、大径部４７の傾斜面と塵埃捕捉傘６７の一方の面７３に挟まれてサイクロン部６６から遠ざかるほど狭くなる略楔形状の空間である。   Further, the dust trap umbrella 67 hits the connecting portion between the large diameter portion 47 and the general portion 48 of the dust collection container 39 to close the dust collection container 39. The large-diameter portion 47 and the dust capturing umbrella 67 of the dust collecting container 39 partition the fine dust collecting chamber 76 that accumulates dust discharged by the cyclone portion 66. The fine dust collection chamber 76 is a substantially wedge-shaped space that is sandwiched between the inclined surface of the large-diameter portion 47 and one surface 73 of the dust trapping umbrella 67 and becomes narrower as the distance from the cyclone portion 66 increases.

他方の面７５は、内筒４２および塵埃捕捉カップ４３よりも大径であり、かつ内筒４２および塵埃捕捉カップ４３に向かって拡径している。   The other surface 75 is larger in diameter than the inner cylinder 42 and the dust trapping cup 43 and is expanded toward the inner cylinder 42 and the dust trapping cup 43.

第二分離部３６は、案内管６５となる回避領域６３を有する基部材７７と、サイクロン部６６の円錐台形状内面６８を備える筒状本体部材７８と、案内管６５の一部を仕切りつつ開口６９、頂部開口７１を有して円錐台形状内面６８を閉じる隔壁部材７９と、を備える。   The second separation portion 36 opens while partitioning a part of the guide tube 65, a base member 77 having an avoidance region 63 to be the guide tube 65, a cylindrical main body member 78 having a truncated cone-shaped inner surface 68 of the cyclone portion 66, and the guide tube 65. 69, and a partition wall member 79 having a top opening 71 and closing the frustoconical inner surface 68.

基部材７７は複数のサイクロン部６６の開口７２を囲んで集塵容器３９内に延びる塵埃捕獲リブ８１を備える。塵埃捕獲リブ８１は第二分離部３６よりも小径で、塵埃捕捉傘６７よりも大径な径寸法を呈する。   The base member 77 includes dust trapping ribs 81 that surround the openings 72 of the plurality of cyclone portions 66 and extend into the dust collecting container 39. The dust trapping rib 81 has a smaller diameter than the second separation portion 36 and a larger diameter than the dust trapping umbrella 67.

なお、第二分離部３６はサイクロン部６６に代えてプリーツフィルタを適用しても良い。この場合、プリーツフィルタは回避領域６３の周囲を囲む環形状を呈し、連結端部側から流れ込む空気から塵埃を分離して非連結端部側へ空気を流出させる。   The second separation unit 36 may be a pleated filter instead of the cyclone unit 66. In this case, the pleated filter has an annular shape surrounding the periphery of the avoidance region 63, separates dust from the air flowing in from the connecting end portion side, and causes the air to flow out to the non-connecting end portion side.

排気管３７は、第二分離部３６の非連結端部側から第一分離部３５へ向かって回避領域６３に入り込み、集塵容器３９の中心線Ｃの延長線（塵埃分離集塵装置８の中心線）に対して交差する方向へ曲がる。排気管３７は、回避領域６３へ向かって窪む凹部８２を備える。排気管３７は、第二分離部３６に対して並行配置される排気口８３へ第二分離部３６から流れ込む空気を排気する。排気管３７は、サイクロン部６６の非連結端部側に覆い被さり、サイクロン部６６の頂部開口７１から流出する空気を塵埃分離集塵装置８の中心側へ向けて集約する。集約された空気は、凹部８２によって一旦、第一分離部３５へ向かい、その後に略直角に向きを変えて排気口８３に至る。   The exhaust pipe 37 enters the avoidance region 63 from the unconnected end portion side of the second separation portion 36 toward the first separation portion 35, and extends from the center line C of the dust collection container 39 (of the dust separation dust collecting device 8. Turn in a direction that intersects the center line. The exhaust pipe 37 includes a recess 82 that is recessed toward the avoidance region 63. The exhaust pipe 37 exhausts the air flowing from the second separation unit 36 to the exhaust port 83 arranged in parallel with the second separation unit 36. The exhaust pipe 37 covers the unconnected end portion side of the cyclone portion 66 and collects the air flowing out from the top opening 71 of the cyclone portion 66 toward the center side of the dust separation and dust collecting device 8. The aggregated air once travels toward the first separation portion 35 by the concave portion 82, and then turns to a substantially right angle and reaches the exhaust port 83.

排気管３７は、隔壁部材７９に覆い被さり案内管６５と排気管３７とで共有される共通隔壁部材８４と、共通隔壁部材８４に覆い被さり排気管３７を仕切る蓋状部材８５と、を備える。なお、排気管３７のうち、回避領域６３に入り込み排気口８３に向かって折れ曲がる部分は、基部材７７に設けられる。   The exhaust pipe 37 includes a common partition member 84 that is shared by the cover guide tube 65 and the exhaust pipe 37, and a lid-shaped member 85 that covers the cover exhaust pipe 37 and covers the common partition member 84. A portion of the exhaust pipe 37 that enters the avoidance region 63 and bends toward the exhaust port 83 is provided in the base member 77.

カバー３８は頂部（すなわち塵埃分離集塵装置８の頂部）に手掛部８６を備える。使用者は、手掛部８６に指を挿入することで塵埃分離集塵装置８をしっかりと保持できる。カバー３８は、排気管３７に対向する天板８７と、天板８７に設けられて回避領域６３へ向けて窪む凹部８８と、手掛部８６を揺動可能に支えるヒンジ機構８９と、手掛部８６へ向かって縮径する円錐形状部９１と、を備える。   The cover 38 includes a handle 86 at the top (that is, the top of the dust separator / collector 8). The user can hold the dust separation and dust collecting device 8 firmly by inserting a finger into the hand grip 86. The cover 38 includes a top plate 87 that faces the exhaust pipe 37, a recess 88 that is provided on the top plate 87 and that is recessed toward the avoidance region 63, a hinge mechanism 89 that swingably supports the handle portion 86, and a hand. A conical shape portion 91 that is reduced in diameter toward the hook portion 86.

凹部８８は、排気管３７の凹部８２に対応して窪む。   The recess 88 is recessed corresponding to the recess 82 of the exhaust pipe 37.

他方、掃除機本体２は、爪部９２と協働して塵埃分離集塵装置８を掃除機本体２に固定するロック機構９３を備える。   On the other hand, the cleaner body 2 includes a lock mechanism 93 that fixes the dust separating and collecting apparatus 8 to the cleaner body 2 in cooperation with the claw portion 92.

ヒンジ機構８９は、隙間９５の反開放側に位置する揺動軸の周りに手掛部８６を支える。ヒンジ機構８９は、隙間９５の開口高さを拡大する。つまり、ヒンジ機構８９は、通常時の隙間９５の開口高さを平均的な指の厚さよりも低く設定しておくことを可能にする。この場合、ヒンジ機構８９は、隙間９５に進入する指の厚さに応じて手掛部８６を揺動させ、隙間９５の開口高さを拡大させる。   The hinge mechanism 89 supports the handle portion 86 around the swing shaft positioned on the opposite side of the gap 95. The hinge mechanism 89 enlarges the opening height of the gap 95. That is, the hinge mechanism 89 makes it possible to set the opening height of the gap 95 in the normal state to be lower than the average finger thickness. In this case, the hinge mechanism 89 swings the handle portion 86 in accordance with the thickness of the finger entering the gap 95, and enlarges the opening height of the gap 95.

手掛部８６は、カバー３８の一部を兼ねて天板８７に対向し凹部８８と協働して手指を挿抜可能に開放する隙間９５を仕切る。また、手掛部８６は、その揺動に追従する爪部９２と、手掛部８６の頂部に配置される略平坦な倒立支持部９６と、を備える。   The handle portion 86 also serves as a part of the cover 38, faces the top plate 87, and cooperates with the recess 88 to partition a gap 95 that opens the finger so that it can be inserted and removed. Further, the handle portion 86 includes a claw portion 92 that follows the swing, and a substantially flat inverted support portion 96 that is disposed on the top of the handle portion 86.

カバー３８の円錐形状部９１は、手掛部８６、ひいては倒立支持部９６へ向かって縮径している。   The conical shape portion 91 of the cover 38 is reduced in diameter toward the handle portion 86 and eventually toward the inverted support portion 96.

倒立支持部９６は、軟質材料の成形品であり、手掛部８６の頂部、ひいてはカバー３８の頂部、塵埃分離集塵装置８の頂部に配置される。   The inverted support part 96 is a molded product of a soft material, and is arranged at the top part of the handle part 86, by extension, the top part of the cover 38, and the top part of the dust separating and collecting device 8.

なお、カバー３８は、倒立支持部９６を覆う保護層９７を備えていても良い。   The cover 38 may include a protective layer 97 that covers the inverted support portion 96.

次に、集塵容器３９が取り外された塵埃分離集塵装置８の倒立支持状態について説明する。   Next, an inverted support state of the dust separation dust collecting apparatus 8 from which the dust collecting container 39 has been removed will be described.

塵埃分離集塵装置８は、掃除に供される度に集塵容器３９の集塵部５８に粗い塵埃を蓄積し、細塵集塵室７６に細かい塵埃を蓄積する。これら塵埃が適宜の蓄積量に達すると、塵埃分離集塵装置８から集塵容器３９を取り外して塵埃を廃棄する必要が生じる。   The dust separating and collecting device 8 accumulates coarse dust in the dust collecting portion 58 of the dust collecting container 39 and accumulates fine dust in the fine dust collecting chamber 76 every time it is cleaned. When these dusts reach an appropriate accumulation amount, it becomes necessary to remove the dust collecting container 39 from the dust separating and collecting device 8 and discard the dust.

このとき、細塵集塵室７６の細かい塵埃は、大径部４７の傾斜面を滑り落ち、一般部４８の側壁内面を伝って集塵容器３９の底部に達して積もり、あるいは集塵部５８の粗い塵埃に降り掛かる。   At this time, the fine dust in the fine dust collecting chamber 76 slides down the inclined surface of the large diameter portion 47 and reaches the bottom of the dust collecting container 39 along the inner surface of the side wall of the general portion 48 or accumulates, or the dust collecting portion 58. Fall on the coarse dust.

そうすると、使用者はハンドル４５を持って集塵容器３９を適宜の廃棄対象（例えば、ゴミ箱）へ運搬し、反転させて塵埃を廃棄する。   Then, the user holds the handle 45 and transports the dust container 39 to an appropriate disposal target (for example, a trash can), and reverses it to discard the dust.

ところで、集塵容器３９が取り外された後、少量の粗い塵埃が内筒４２や塵埃捕捉カップ４３に付着していたり、少量の細かい塵埃が塵埃捕捉傘６７に付着していたりすることがある。これら塵埃が付着している塵埃分離集塵装置８の残部（集塵容器３９以外の部分）を手に持ったまま移動したり、いずれかの場所へ無造作に放置すると、付着していた塵埃が脱落し散らばってしまう。   By the way, after the dust collecting container 39 is removed, a small amount of coarse dust may adhere to the inner cylinder 42 or the dust capturing cup 43, or a small amount of fine dust may adhere to the dust capturing umbrella 67. If you move the remaining part of the dust separating and collecting device 8 (parts other than the dust collecting container 39) with these in your hand or leave it in any place, the attached dust will be removed. Drop off and scatter.

そこで、本実施形態に係る塵埃分離集塵装置８は、第二分離部３６を下方に、第一分離部３５を上方にして、つまり天地を反転させて置くことができる。   Therefore, the dust separating and collecting apparatus 8 according to the present embodiment can be placed with the second separating portion 36 downward and the first separating portion 35 upward, that is, with the top and bottom reversed.

図５は、本発明の実施形態に係る塵埃分離集塵装置の残部が倒立している状態を示す断面図である。   FIG. 5 is a cross-sectional view showing a state where the remaining part of the dust separation and dust collecting apparatus according to the embodiment of the present invention is inverted.

図５に示すように、本実施形態に係る塵埃分離集塵装置８は、集塵容器３９を取り外した状態で、倒立支持部９６を下端に配置し、第二分離部３６を下方に内筒４２を上方に配置し、塵埃捕捉カップ４３を上方に向ける反転姿勢で起立、つまり倒立できる。   As shown in FIG. 5, the dust separating and collecting apparatus 8 according to the present embodiment has the inverted support portion 96 disposed at the lower end and the second separating portion 36 facing downward in the inner cylinder with the dust collecting container 39 removed. It is possible to stand upside down, that is, in an inverted position, with the 42 positioned upward and the dust capture cup 43 facing upward.

集塵容器３９が取り外された塵埃分離集塵装置８の重心Ｇは、倒立支持部９６の投影内に配置されている。   The center of gravity G of the dust separating and collecting apparatus 8 from which the dust collecting container 39 has been removed is disposed within the projection of the inverted support portion 96.

倒立姿勢の塵埃分離集塵装置８は、仮に、内筒４２や塵埃捕捉カップ４３に付着する塵埃Ｄ１が脱落しても、塵埃捕捉傘６７の他方の面７５で受け止めることができる。他方の面７５は、内筒４２および塵埃捕捉カップ４３に向かって拡径しているため、捕らえた塵埃Ｄ１をその中心側へ寄せて確実に捕獲する。   Even if dust D1 adhering to the inner cylinder 42 or the dust catching cup 43 falls off, the dust separating / collecting device 8 in the inverted posture can be received by the other surface 75 of the dust catching umbrella 67. Since the other surface 75 is enlarged in diameter toward the inner cylinder 42 and the dust trapping cup 43, the trapped dust D <b> 1 is moved toward its center side and reliably captured.

また、倒立姿勢の塵埃分離集塵装置８は、仮に、塵埃捕捉傘６７に付着する塵埃Ｄ２が脱落しても、塵埃捕獲リブ８１よりも内側の領域で受け止めることができる。   Moreover, even if the dust separation dust collecting apparatus 8 in the inverted posture falls off the dust D2 adhering to the dust trapping umbrella 67, it can be received in a region inside the dust trapping rib 81.

つまり、塵埃分離集塵装置８は、集塵容器３９を取り外した状態であっても、略水平な場所に倒立させることで内筒４２、塵埃捕捉カップ４３、塵埃捕捉傘６７に付着している塵埃を捕獲し、これら塵埃が周囲に散らばることを防ぐ。   That is, the dust separating and collecting apparatus 8 is attached to the inner cylinder 42, the dust catching cup 43, and the dust catching umbrella 67 by being inverted in a substantially horizontal place even when the dust collecting container 39 is removed. It captures dust and prevents it from being scattered around.

ところで、倒立姿勢から正常姿勢へ塵埃分離集塵装置８を戻すときは、カバー３８の円錐形状部９１に手や指を回し込むことでしっかりと把持することができる。したがって、使用者は集塵容器３９内の塵埃を廃棄した後（廃棄する前も当然に）、集塵容器３９を適宜に置き、代わって塵埃分離集塵装置８を把持して廃棄対象（例えば、ゴミ箱）へ運搬し、反転させて塵埃を廃棄できる。   By the way, when returning the dust separating and collecting apparatus 8 from the inverted posture to the normal posture, it can be firmly held by turning a hand or a finger into the conical portion 91 of the cover 38. Therefore, after the user discards the dust in the dust collecting container 39 (and naturally before discarding), the user appropriately places the dust collecting container 39, and instead holds the dust separating dust collecting device 8 to be disposed of (for example, , Can be transported to the trash) and inverted to discard the dust.

本実施形態に係る塵埃分離集塵装置８は、頂部に平坦な倒立支持部９６を備えるため、集塵容器３９が取り外された状態で略水平な場所に倒立できる。このため、塵埃分離集塵装置８は、集塵容器３９が取り外されても、無造作な姿勢のまま放置されたり、使用者の手に把持されたまま運搬されることがなく、集塵容器３９以外の部分に残留する塵埃を様々な箇所に散布する虞がなくなり、清掃達成の観点からも、衛生上の観点からも好ましい。   Since the dust separating and collecting apparatus 8 according to this embodiment includes the flat inverted support part 96 at the top, the dust separating and collecting apparatus 8 can be inverted in a substantially horizontal place with the dust collecting container 39 removed. For this reason, even if the dust collecting container 39 is removed, the dust separating dust collecting device 8 is not left in a casual posture or is transported while being held by the user's hand. There is no possibility that dust remaining in other parts will be scattered in various places, which is preferable from the viewpoint of achieving cleaning and from the viewpoint of hygiene.

また、本実施形態に係る塵埃分離集塵装置８は、塵埃捕捉傘６７を備えることによって、第二分離部３６に遠心分離方式のサイクロン部６６を採用しても、細かい塵埃を集塵容器３９に蓄積することができる一方で、集塵容器３９を外しても集塵容器３９以外の部分に残留する塵埃を受け止め、塵埃の散布をより確実に防ぐことができる。   Further, the dust separating and collecting apparatus 8 according to the present embodiment includes the dust capturing umbrella 67, so that even if the centrifugal separator 66 is used for the second separating portion 36, fine dust is collected in the dust collecting container 39. On the other hand, even if the dust collecting container 39 is removed, dust remaining in the part other than the dust collecting container 39 can be received and dust can be more reliably prevented from being scattered.

さらに、本実施形態に係る塵埃分離集塵装置８は、倒立支持部９６へ向かって縮径する円錐形状部９１を備えるため、倒立姿勢の塵埃分離集塵装置８の残部を確実に把持して、安定良く取り扱うことができる。   Furthermore, since the dust separating and collecting device 8 according to the present embodiment includes the conical portion 91 whose diameter decreases toward the inverted support portion 96, the remaining portion of the dust separating and collecting device 8 in the inverted posture is securely gripped. Can be handled stably.

さらにまた、本実施形態に係る塵埃分離集塵装置８は、倒立支持部９６を覆う保護層９７を備えるため、倒立支持部９６の健全性、倒立状態の安定性を長期に保つことができる。また、保護層９７に滑りにくい素材を適用すれば倒立状態の安定性を飛躍的に高められる。   Furthermore, since the dust separating and collecting apparatus 8 according to the present embodiment includes the protective layer 97 that covers the inverted support part 96, the soundness of the inverted support part 96 and the stability of the inverted state can be maintained for a long time. In addition, if a non-slip material is applied to the protective layer 97, the stability of the inverted state can be dramatically improved.

また、本実施形態に係る塵埃分離集塵装置８は、倒立支持部９６を軟質材料で成形することによっても、倒立支持部９６の健全性、倒立状態の安定性を長期に保つことができる。また、滑りにくい軟質材料を適用すれば倒立状態の安定性を飛躍的に高められる。   Moreover, the dust separation dust collector 8 which concerns on this embodiment can maintain the soundness of the inverted support part 96 and the stability of an inverted state for a long time also by shape | molding the inverted support part 96 with a soft material. In addition, if a soft material that is difficult to slip is applied, the stability of the inverted state can be dramatically improved.

したがって、本実施形態に係る塵埃分離集塵装置８およびこれを備える電気掃除機１によれば、集塵容器３９を取り外した状態で残留している塵埃を散布する虞の少ない姿勢で自立し、清掃達成の観点、衛生上の観点で良好である。   Therefore, according to the dust separation and dust collection device 8 and the vacuum cleaner 1 including the dust separation device 8 according to the present embodiment, the dust separation container 39 is self-supporting in a posture in which there is little possibility of scattering dust remaining in a state in which the dust collection container 39 is removed. Good in terms of achieving cleaning and hygiene.

なお、本実施形態に係る電気掃除機１は、キャニスタ型のものに限らず、アップライト型、スティック型、あるいはハンディ型などのものであってもよい。   The vacuum cleaner 1 according to the present embodiment is not limited to a canister type, but may be an upright type, a stick type, or a handy type.
