A large number of vent holes 18 are formed in the / 3 portion. The flange portion 19 extending from the lower end of the first cylindrical cylindrical body 9 toward the inner surface of the dust collection container 5 is formed in a shape that curves downward as it approaches the inner surface of the dust collection container 5. A small gap is formed between the outer periphery of 9 and the inner surface of the dust collecting container 5 (see FIGS. 1 and 2).

第1の円筒状筒体9内に、第1の円筒状筒体9と同軸上に配置される第2の円筒状筒体16は、高さ方向略中央位置から外周方向に延設したフランジ部20を第1の円筒状筒体9下端部に係脱自在に係合している(図1、図2参照)。   A second cylindrical cylinder 16 disposed coaxially with the first cylindrical cylinder 9 in the first cylindrical cylinder 9 is a flange extending from the substantially central position in the height direction in the outer peripheral direction. The portion 20 is detachably engaged with the lower end portion of the first cylindrical cylindrical body 9 (see FIGS. 1 and 2).

第2の円筒状筒体16のフランジ部20上方位置に形成された連通孔21は、第1の円筒状筒体9と第2の円筒状筒体16とで囲まれる空間と、第2の円筒状筒体16内とを連通している。第2の円筒状筒体16上部には排出口22が形成され、排出口22を囲むと共に、排出口22と集塵空間8の下部とを連通させる図示しない排出通路が第2の円筒状筒体16の側面に形成されている(図1、図2参照)。   The communication hole 21 formed at a position above the flange portion 20 of the second cylindrical cylinder 16 includes a space surrounded by the first cylindrical cylinder 9 and the second cylindrical cylinder 16, and a second The inside of the cylindrical cylinder 16 is communicated. A discharge port 22 is formed in the upper portion of the second cylindrical cylinder 16, and a discharge passage (not shown) that surrounds the discharge port 22 and communicates the discharge port 22 with the lower portion of the dust collection space 8 is the second cylindrical tube. It is formed on the side surface of the body 16 (see FIGS. 1 and 2).

第2の円筒状筒体16内に第2の円筒状筒体16と同軸上に配設される円筒状の排気筒17は、第2の円筒状筒体16に一体的に固定されており、下端の排気孔23は蓋体12の排気口15に連通している。排気筒17は上端が第2の円筒状筒体16の連通孔21より上方位置まで形成されている(図1、図2参照)。   A cylindrical exhaust cylinder 17 disposed coaxially with the second cylindrical cylinder 16 in the second cylindrical cylinder 16 is integrally fixed to the second cylindrical cylinder 16. The exhaust hole 23 at the lower end communicates with the exhaust port 15 of the lid 12. The upper end of the exhaust cylinder 17 is formed up to a position above the communication hole 21 of the second cylindrical cylinder 16 (see FIGS. 1 and 2).

排気筒17外周の連通孔21と対向する位置から上方に向かって形成された螺旋状の突条24は、突条24外周が第2の円筒状筒体16内面に近接、または当接するように形成されており、連通孔21から第2の円筒状筒体16内に導かれた空気を旋回させ、空気から微細な塵埃を分離させて排出口22から放出するようになっている(図1、図2参照)。   The spiral protrusion 24 formed upward from a position facing the communication hole 21 on the outer periphery of the exhaust cylinder 17 is such that the outer periphery of the protrusion 24 is close to or in contact with the inner surface of the second cylindrical cylinder 16. It is formed, and the air guided into the second cylindrical cylinder 16 from the communication hole 21 is swirled to separate fine dust from the air and discharged from the discharge port 22 (FIG. 1). FIG. 2).

集塵容器5外周面の、排気口15に対応する位置には、排気口15を開閉自在に覆うフィルタ25が配設されている。フィルタ25は、上流側から目の粗いウレタン等からなる第1フィルタ26、不織布等からなる第2フィルタ27、微細な塵埃を除去するプリーツ形状の第3フィルタ28との3層で構成されている。そして、フィルタ25はフィルタケース29に収納され、フィルタケース29の一側は集塵容器5に回動自在に軸支されると共に、他側は、他側に形成された爪部30が集塵容器5に係脱自在に係合する(図1、図2参照)。   A filter 25 that covers the exhaust port 15 in an openable and closable manner is disposed at a position corresponding to the exhaust port 15 on the outer peripheral surface of the dust collecting container 5. The filter 25 is composed of three layers: a first filter 26 made of urethane or the like having coarse eyes from the upstream side, a second filter 27 made of nonwoven fabric, etc., and a pleated third filter 28 for removing fine dust. . The filter 25 is housed in a filter case 29. One side of the filter case 29 is pivotally supported by the dust collecting container 5 and the other side is provided with a claw portion 30 formed on the other side. The container 5 is detachably engaged (see FIGS. 1 and 2).

第3フィルタ28は集塵効率を向上させるためにプリーツ状に形成されているため、第1フィルタ26と第3フィルタ28との間隔が極端に狭く、且つ、第1フィルタ26の一部が目詰まりした場合には、第1フィルタ26の目詰まりした部分に対応する第3フィルタ28には風が流れなくなってしまう虞がある。そうなれば、第3フィルタ28の部分的にしか風が流れなくなり、第3フィルタ28の寿命が低下すると共に、集塵効率が低下してしまう。これに対して、本発明の形態では、第1フィルタ26と第3フィルタ28との間に第2フィルタ27を配置しているため、第2フィルタ27が第1フィルタ26と第3フィルタ28との間隔を所定距離保つためのスペーサー的な働きをする。この結果、第1フィルタ26の一部が目詰まりした場合でも、第2フィルタ27のスペースを介して第1フィルタ26の目詰まりした部分に対応する第3フィルタ28にも風を流れ込ますことができるため、第3フィルタ28の寿命低下を防止することができると共に、集塵効率の低下を防止することができるようになっている。   Since the third filter 28 is formed in a pleat shape in order to improve dust collection efficiency, the distance between the first filter 26 and the third filter 28 is extremely narrow, and a part of the first filter 26 is visible. When clogged, the wind may not flow through the third filter 28 corresponding to the clogged portion of the first filter 26. If it becomes so, a wind will flow only partly of the 3rd filter 28, and while the lifetime of the 3rd filter 28 will fall, dust collection efficiency will fall. On the other hand, in the embodiment of the present invention, since the second filter 27 is disposed between the first filter 26 and the third filter 28, the second filter 27 is connected to the first filter 26 and the third filter 28. It acts as a spacer to keep the distance of the predetermined distance. As a result, even when a part of the first filter 26 is clogged, the air flows into the third filter 28 corresponding to the clogged part of the first filter 26 through the space of the second filter 27. Therefore, the lifetime of the third filter 28 can be prevented from being reduced, and the dust collection efficiency can be prevented from being lowered.

このように構成された電気掃除機は、吸込具本体2の吸込口1から吸引された塵埃等は空気と共に集塵容器5の集塵空間8内に、且つ、旋回方向に導かれ、集塵空間8内で旋回し、比較的大きな塵埃等は空気から分離されて、鍔部19と集塵容器5との間隔から集塵容器5下方の集塵空間8に蓄積する。   In the vacuum cleaner configured as described above, dust or the like sucked from the suction port 1 of the suction tool body 2 is guided together with air into the dust collection space 8 of the dust collection container 5 and in the swirl direction, and dust collection. Rotating in the space 8, relatively large dust or the like is separated from the air and accumulated in the dust collection space 8 below the dust collection container 5 from the interval between the flange 19 and the dust collection container 5.

比較的大きな塵埃等が分離された空気は、第1の円筒状筒体9の通気孔18と第2の円筒状筒体16の連通孔21を通過して第2の円筒状筒体16内に導かれ、排気筒17の突条24により旋回流となり、第2の円筒状筒体16内で旋回しながら上昇する。この旋回上昇気流により微細な塵埃が空気から分離され、分離された塵埃は排出口22から排出され、排出通路を通って集塵空間8の下部に蓄積する。   The air from which relatively large dust or the like has been separated passes through the vent hole 18 of the first cylindrical cylindrical body 9 and the communication hole 21 of the second cylindrical cylindrical body 16 and enters the second cylindrical cylindrical body 16. And is swirled by the protrusions 24 of the exhaust cylinder 17 and rises while swirling in the second cylindrical cylinder 16. Fine dust is separated from the air by the swirling updraft, and the separated dust is discharged from the discharge port 22 and accumulated in the lower part of the dust collection space 8 through the discharge passage.

一方、塵埃が分離された空気は、排気筒17の上方開口に向かって導かれて下降し、フィルタ25を通過する際に微小の微細な塵埃は除去されて電動送風機へ流れる。集塵容器5内に溜まった塵埃等を廃棄する際には、蓋体12を開放すると、集塵容器5内の塵埃等は自重で落下して廃棄される。   On the other hand, the air from which the dust has been separated is guided and descends toward the upper opening of the exhaust cylinder 17, and when passing through the filter 25, minute fine dust is removed and flows to the electric blower. When the dust or the like accumulated in the dust collection container 5 is discarded, when the lid 12 is opened, the dust or the like in the dust collection container 5 falls and is discarded by its own weight.

集塵容器5外の、排気筒17の排気孔23より下流側にフィルタ25を配設しているため、集塵容器5を小型化しても集塵効率を向上させることができる。また、フィルタ25をメンテナンスする際には、図2に示すようにフィルタケース29の他端の爪部30の係合を解除することにより、集塵容器5の外側からフィルタ25の状態を容易に確認することができるため、フィルタ25のメンテナンス性を向上させることができる。   Since the filter 25 is disposed outside the dust collection container 5 and downstream of the exhaust hole 23 of the exhaust cylinder 17, the dust collection efficiency can be improved even if the dust collection container 5 is downsized. Further, when maintaining the filter 25, the state of the filter 25 can be easily changed from the outside of the dust collecting container 5 by releasing the engagement of the claw portion 30 at the other end of the filter case 29 as shown in FIG. Since it can be confirmed, the maintainability of the filter 25 can be improved.

尚、本発明の形態では、集塵空間8は集塵容器5と蓋体12とにより構成したが、集塵
容器を、上面を開口した有底円筒状に形成し、集塵空間の上部を集塵容器が装着される掃除機本体の一部により構成すると共に、集塵容器外周面の、排気筒の排気孔より下流位置にフィルタを配置してもよい。この構成では、排気筒を集塵容器底面と一体的に形成することができる。
In the embodiment of the present invention, the dust collection space 8 is constituted by the dust collection container 5 and the lid body 12. However, the dust collection container is formed in a bottomed cylindrical shape having an upper surface opened, and the upper part of the dust collection space is formed. The filter may be disposed at a position downstream of the exhaust hole of the exhaust tube on the outer peripheral surface of the dust collector while being configured by a part of the cleaner body to which the dust collector is mounted.
