It is detachably connected by the same mechanism as the stop piece 17Ca 114 ).

防音シート部１７Ｃｂは、例えば、通気性および可撓性を有する発泡樹脂シートまたは樹脂繊維製不織布等からなり、ケース本体１７Ｃａ1の枠形円筒部１７Ｃａ11の内側の奥行き寸法と同等の幅寸法および枠形円筒部１７Ｃａ11の内側の円周と同等の長さ寸法を有する矩形のシートである。 The soundproof sheet portion 17Cb is made of, for example, a breathable and flexible foamed resin sheet or a non-woven fabric made of resin fiber, and has a width dimension equivalent to the inner depth dimension of the frame-shaped cylindrical portion 17Ca 11 of the case body 17Ca 1 . It is a rectangular sheet having a length dimension equivalent to the inner circumference of the frame-shaped cylindrical portion 17Ca 11 .

防音シート部１７Ｃｂは、長手方向の一端部１７Ｃｂ1と他端部１７Ｃｂ2とを突き合わせるようにして筒状に巻かれてケース部１７Ｃａの枠形円筒部１７Ｃａ11内に収納される。このとき、防音シート部１７Ｃｂの一端部１７Ｃｂ1と他端部１７Ｃｂ2とが大型リブ１７Ｃａ112の突片部１７Ｃａ1121に突き当てられかつ押え片部１７Ｃａ1122にてぶらつかないよう押さえられる。また、防音シート部１７Ｃｂの一方の長辺部が複数の小型リブ１７Ｃａ113によってぶらつかないよう押さえられる。 The soundproof sheet portion 17Cb is wound into a tubular shape so that one end portion 17Cb 1 and the other end portion 17Cb 2 in the longitudinal direction abut against each other, and is housed in the frame-shaped cylindrical portion 17Ca 11 of the case portion 17Ca. At this time, one end 17Cb 1 and the other end 17Cb 2 of the soundproof sheet portion 17Cb are abutted against the projecting piece portion 17Ca 1121 of the large rib 17Ca 112 and are pressed by the pressing piece portion 17Ca 1122 so as not to hang. Further, one long side portion of the soundproof sheet portion 17Cb is suppressed by a plurality of small ribs 17Ca 113 so as not to hang around.

このように、枠形円筒部１７Ｃａ11の内周面に沿って防音シート部１７Ｃｂを位置決め固定することにより、防音シート部１７Ｃｂを枠形円筒部１７Ｃａ11の通気性を有する外周壁として機能させることができる。つまり、電動送風機３０の外周部から径方向に向かって噴出する気流を電動送風機３０の外周側に配置された防音シート部１７Ｃｂに通すことができるため、電動送風機３０の排気の流れがスムーズとなる。また、防音シート部１７Ｃｂを通過した気流の一部を基板収納部１７Ｃａ12内に通して回路基板９０を効率よく冷却することができる。なお、回路基板９０を冷却した気流はカバー部材１７Ｃａ2の通気口１７Ｃａ221を通過してコードリール４０の方へ流れる（図２）。 By positioning and fixing the soundproof sheet portion 17Cb along the inner peripheral surface of the frame-shaped cylindrical portion 17Ca 11 in this way, the soundproof sheet portion 17Cb can function as a breathable outer peripheral wall of the frame-shaped cylindrical portion 17Ca 11 . Can be done. That is, since the airflow ejected from the outer peripheral portion of the electric blower 30 in the radial direction can be passed through the soundproof sheet portion 17Cb arranged on the outer peripheral side of the electric blower 30, the flow of the exhaust of the electric blower 30 becomes smooth. .. Further, a part of the airflow that has passed through the soundproof sheet portion 17Cb can be passed through the substrate housing portion 17Ca 12 to efficiently cool the circuit board 90. The airflow that has cooled the circuit board 90 passes through the vent 17Ca 221 of the cover member 17Ca 2 and flows toward the cord reel 40 (FIG. 2).

＜掃除機本体の動作およびメンテナンスについて＞
図１に示すように、本発明の電気掃除機の掃除機本体１は、清掃時には、図示しないハンドルおよび操作部を有する可撓性ホース、延長パイプおよび吸込口体が接続される。
操作部にて電源をＯＮにすると、電動送風機３０が駆動し、被清掃面上の塵埃を空気と共に吸い込んで清掃する。吸込口体に吸い込まれた塵埃を含む空気は、延長パイプおよび可撓性ホースを介して掃除機本体１内に吸引される。 <About the operation and maintenance of the vacuum cleaner body>
As shown in FIG. 1, the vacuum cleaner body 1 of the vacuum cleaner of the present invention is connected to a flexible hose, an extension pipe, and a suction port having a handle and an operation portion (not shown) at the time of cleaning.
When the power is turned on in the operation unit, the electric blower 30 is driven to suck dust on the surface to be cleaned together with air for cleaning. The air containing dust sucked into the suction port body is sucked into the vacuum cleaner main body 1 via the extension pipe and the flexible hose.

以下、図１～図９を参照しながら掃除機本体１内における空気の流れを説明する。なお、空気の流れは、図２中の矢印Ｆ1～Ｆ10の順となっている。
塵埃を含む空気は、まず、駆動装置１０の吸引口１１ｂに流入し（矢印Ｆ1）、吸引口１１ｂと第１通風口１１ｃの間の第１通風経路１７ａ（第１部材１７Ａの内部）を通り（矢印Ｆ2）、集塵装置２０のダストカップ２１の空気流入口２１ａ2に流入する（矢印Ｆ3）。 Hereinafter, the flow of air in the vacuum cleaner main body 1 will be described with reference to FIGS. 1 to 9. The air flow is in the order of arrows F 1 to F 10 in FIG.
The air containing dust first flows into the suction port 11b of the drive device 10 (arrow F1), and first passes through the first ventilation path 17a (inside the first member 17A) between the suction port 11b and the first ventilation port 11c. The street (arrow F 2 ) flows into the air inlet 21a 2 of the dust cup 21 of the dust collector 20 (arrow F 3 ).

ダストカップ２１内に流入した塵埃を含む空気は、ダストカップ２１内を旋回し、この間に比較的大きな第１の塵埃は遠心力によりダストカップ２１の内周面側を旋回し、微細な塵埃を含む空気はメッシュ部材２２Ａａ111へ向かう（矢印Ｆ4）。これにより、比較的大きな第１の塵埃はダストカップ２１内に溜まる。 The air containing dust that has flowed into the dust cup 21 swirls in the dust cup 21, and during this time, the relatively large first dust swirls on the inner peripheral surface side of the dust cup 21 due to centrifugal force to collect fine dust. The air contained is directed to the mesh member 22Aa 111 (arrow F 4 ). As a result, the relatively large first dust is collected in the dust cup 21.

メッシュ部２２Ａａ111を通過した第１の塵埃よりも微細な第２の塵埃を含む空気は、第１遠心分離部２２Ａ内に流入し（矢印Ｆ5）、第２遠心分離部２２Ｂの複数の遠心分離筒２２Ｂａの内部へ流入して内周面に沿って旋回する。 Air containing a second dust finer than the first dust that has passed through the mesh portion 22Aa 111 flows into the first centrifuge portion 22A (arrow F 5 ), and a plurality of centrifuges of the second centrifuge portion 22B. It flows into the inside of the separation cylinder 22Ba and turns along the inner peripheral surface.

第２の塵埃を含む空気が遠心分離筒２２Ｂａの内周面に沿って旋回ことにより、第２の塵埃は遠心分離されて遠心分離ユニット２２内に溜まる。一方、第２の塵埃が除去された空気は、複数の遠心分離筒２２Ｂａの内部（矢印Ｆ6）を通って回動部２２Ｄの空気排出口２２Ｄａ12から駆動装置１０のフィルター５０を通過して第２通風口１１ｄ内に流入する（矢印Ｆ7）。このとき、複数の遠心分離筒２２Ｂａにて捕捉されなかった第２の塵埃よりも微細な塵埃がフィルター５０にて捕捉される。 The air containing the second dust swirls along the inner peripheral surface of the centrifuge cylinder 22Ba, so that the second dust is centrifuged and collected in the centrifuge unit 22. On the other hand, the air from which the second dust has been removed passes through the inside of the plurality of centrifuge cylinders 22Ba (arrow F 6 ), from the air discharge port 22Da 12 of the rotating portion 22D, and through the filter 50 of the drive device 10. It flows into the second ventilation port 11d (arrow F 7 ). At this time, the filter 50 captures dust finer than the second dust that was not captured by the plurality of centrifuge cylinders 22Ba.

駆動装置１０内に流入した清浄化された空気は、第２通風口１１ｄと電動送風機３０との間の上流側第２通風経路１７ｂ（上流側第２部材１７Ｂの内部）を通って電動送風機３０内に流入し、電動送風機３０の外周部から流出した空気は下流側第２通風経路１７ｃを通過する。この際、空気は、基板収納部１７Ｃａ12内に直接流入して回路基板９０を冷却する、あるいは防音シート部１７Ｃｂを通過した後に基板収納部１７Ｃａ12内に流入して回路基板９０を冷却する、あるいは防音シート部１７Ｃｂを通過した後にコードリール４０の方へ流れる（矢印Ｆ8）。 The purified air that has flowed into the drive device 10 passes through the upstream second ventilation path 17b (inside the upstream second member 17B) between the second ventilation port 11d and the electric blower 30, and is the electric blower 30. The air that has flowed in and has flowed out from the outer peripheral portion of the electric blower 30 passes through the second ventilation path 17c on the downstream side. At this time, air directly flows into the substrate housing portion 17Ca 12 to cool the circuit board 90, or flows into the substrate housing portion 17Ca 12 after passing through the soundproof sheet portion 17Cb to cool the circuit board 90. Alternatively, it flows toward the cord reel 40 after passing through the soundproof sheet portion 17Cb (arrow F 8 ).

基板収納部１７Ｃａ12内に流入した空気はカバー部材１７Ｃａ2内から流出してコードリール４０の方へ流れる空気と合流し、コードリール４０の周囲を回り込み（矢印Ｆ9）、排気口１１ｅ1から外部に排出される（矢印Ｆ10）。 The air that has flowed into the board storage portion 17Ca 12 flows out from the inside of the cover member 17Ca 2 and joins the air flowing toward the cord reel 40, wraps around the cord reel 40 (arrow F 9 ), and enters from the exhaust port 11e 1 . It is discharged to the outside (arrow F 10 ).

次に、清掃後の掃除機本体１のメンテナンスについて説明する。
集塵装置２０のメッシュ部材２２Ａａ111の除塵およびダストカップ２１内に溜まった第１の塵埃の圧縮は、回動部２２ＤのハンドルＤｃ1を所定方向に回すことにより同時に行われる。この際、除塵および圧縮は、集塵装置２０を駆動装置１０に装着したままの状態でも行うことができるが、適切な除塵および圧縮は、集塵装置２０を駆動装置１０から取り外し、集塵装置２０を立てた状態で行うことが望ましい。 Next, maintenance of the vacuum cleaner main body 1 after cleaning will be described.
Dust removal from the mesh member 22Aa 111 of the dust collector 20 and compression of the first dust collected in the dust cup 21 are simultaneously performed by turning the handle Dc 1 of the rotating portion 22D in a predetermined direction. At this time, dust removal and compression can be performed even when the dust collector 20 is attached to the drive device 10, but proper dust removal and compression can be performed by removing the dust collector 20 from the drive device 10 and collecting the dust. It is desirable to carry out with 20 upright.

駆動装置１０に装着された集塵装置２０を取り外す際は、集塵装置２０のハンドル２２Ｄｃ1を手で掴んで引っ張ることにより、駆動装置１０の一対の係合凹部１１ｇに係合した集塵装置２０の一対のロック爪２２Ｄｂ2が揺動して各係合凹部１１ｇから離脱するため、使用者はハンドル２２Ｄｃ1を引き上げる１ステップの動作で集塵装置２０を取り外すことができる。ハンドル２２Ｄｃ1は、そのハンドル本体２２Ｄｃ11を手で掴みやすいように円筒形状の直径が下方に向かうにつれて小さくなっている。 When removing the dust collector 20 mounted on the drive device 10, the dust collector is engaged with the pair of engaging recesses 11g of the drive device 10 by grasping and pulling the handle 22Dc 1 of the dust collector 20 by hand. Since the pair of lock claws 22Db 2 of 20 swings away from each engaging recess 11g, the user can remove the dust collector 20 by a one-step operation of pulling up the handle 22Dc 1 . The handle 22Dc 1 has a cylindrical shape whose diameter decreases downward so that the handle body 22Dc 11 can be easily grasped by hand.

駆動装置１０から取り外した集塵装置２０を、床面などの安定した面上に立てた状態で載置し、ハンドル２２Ｄｃ1に示された矢印の方向（時計回り方向）にハンドル２２Ｄｃ1を回す。これにより、ハンドル２２Ｄｃ1と連結した第２遠心分離部２２Ｂが回転する。
第２遠心分離部２２Ｂが回転することにより、第１遠心分離部２２Ａの内筒部２２Ａａの圧縮スクリュー部２２Ａａ2が回転し、ダストカップ２１内の底に溜まった第１の塵埃が圧縮される。 The dust collector 20 removed from the drive device 10 is placed upright on a stable surface such as a floor surface, and the handle 22Dc 1 is turned in the direction of the arrow indicated by the handle 22Dc 1 . .. As a result, the second centrifuge 22B connected to the handle 22Dc 1 rotates.
As the second centrifuge 22B rotates, the compression screw portion 22Aa 2 of the inner cylinder 22Aa of the first centrifuge 22A rotates, and the first dust collected at the bottom of the dust cup 21 is compressed. ..

ダストカップ２１内の第１の塵埃を廃棄する際は、ロック部２１ｃのロック解除ボタン２１を押すことにより底部２１ｂが開き、ダストカップ２１内の第１の塵埃が落下して廃棄される。このとき、内筒部２２Ａａが下がるため、カップ部２２Ａｂ内に溜まった第２の塵埃も内筒部２２Ａａ内を通って廃棄される。
また、集塵装置２０は、ダストカップ２１、第１遠心分離部２２Ａ、第２遠心分離部２２ｂおよび回動部２２ｄに分解できるため、これらをそれぞれ水洗いすることができる。
また、定期的にフィルター５０を取り外して水洗いすることが推奨される。
集塵装置２０およびフィルター５０の洗浄後、電気掃除機の使用前にはこれらを組み立てて駆動装置１０に取り付ける。 When discarding the first dust in the dust cup 21, the bottom portion 21b is opened by pressing the unlock button 21 of the lock portion 21c, and the first dust in the dust cup 21 is dropped and discarded. At this time, since the inner cylinder portion 22Aa is lowered, the second dust collected in the cup portion 22Ab is also discarded through the inner cylinder portion 22Aa.
Further, since the dust collector 20 can be disassembled into a dust cup 21, a first centrifugal separation section 22A, a second centrifugal separation section 22b, and a rotating section 22d, each of them can be washed with water.
It is also recommended to remove the filter 50 and wash it with water on a regular basis.
After cleaning the dust collector 20 and the filter 50, they are assembled and attached to the drive device 10 before using the vacuum cleaner.

（実施形態２）
実施形態１では集塵装置２０を横に倒して駆動装置１０に装着する場合を例示したが、集塵装置２０を立てた状態で駆動装置１０に装着するようにしてもよい。この場合、図６に示した上流側第２部材１７Ｂが上方に配置され、かつ下流側第２部材１７Ｃが下方に配置され、電動送風機３０の上方から空気が流入するように構成される。また、第１部材１７Ａにおいて、第１通風口１１ｃの位置は変更せず、接続口１７Ａａを下流側第２部材１７Ｃの前方に配置させる。 (Embodiment 2)
In the first embodiment, the case where the dust collector 20 is tilted sideways and attached to the drive device 10 is illustrated, but the dust collector 20 may be attached to the drive device 10 in an upright state. In this case, the upstream side second member 17B shown in FIG. 6 is arranged above, and the downstream side second member 17C is arranged below, so that air flows in from above the electric blower 30. Further, in the first member 17A, the position of the first ventilation port 11c is not changed, and the connection port 17Aa is arranged in front of the second member 17C on the downstream side.

（実施形態３）
実施形態１では集塵装置２０のダスト分離部である遠心分離ユニット２２が第１および第２遠心分離部２２Ａ、２２Ｂを備えたマルチサイクロン方式である場合を例示したが、ダスト分離部はこれに限定されるものではなく、例えば、第２遠心分離部２２Ｂの代わりにフィルターを用いてもよい。
この構成によれば、集塵装置側のフィルターと駆動装置側のフィルターとの二重フィルター方式を実現することができる。 (Embodiment 3)
In the first embodiment, the case where the centrifugal separation unit 22 which is the dust separation part of the dust collector 20 is a multi-cyclone system including the first and second centrifugal separation parts 22A and 22B is illustrated, but the dust separation part includes this. Without limitation, for example, a filter may be used instead of the second centrifuge 22B.
According to this configuration, it is possible to realize a double filter system of a filter on the dust collector side and a filter on the drive device side.
