そして、ゴムローラ（ブレーキローラ）３２８の軸部３２９が長孔３２７の後端部に移動している状態では、電源コード３４ｂを巻き取る方向にコードリール３４を回転付勢している渦巻きバネ（図示せず）のバネ力により、ゴムローラ３２８がブレーキドラム３４ａに圧接されて、コードリール３４が渦巻きバネ（図示せず）のバネ力で回転するのを阻止している。尚、電源コード３４ｂをコードリール３４から引き出すときには、ゴムローラ（ブレーキローラ）３２８の軸部３２９が長孔３２７の前側に移動して、ゴムローラ３２８のブレーキドラム３４ａへの圧接が解除され、ブレーキが解除される。   In the state where the shaft portion 329 of the rubber roller (brake roller) 328 is moved to the rear end portion of the long hole 327, a spiral spring (see FIG. 5) that urges the cord reel 34 to rotate in the direction of winding the power cord 34b. The rubber roller 328 is pressed against the brake drum 34a by the spring force (not shown), and the cord reel 34 is prevented from rotating by the spring force of the spiral spring (not shown). When the power cord 34b is pulled out from the cord reel 34, the shaft portion 329 of the rubber roller (brake roller) 328 moves to the front side of the long hole 327, the pressure contact of the rubber roller 328 to the brake drum 34a is released, and the brake is released. Is done.

また、ブレーキが解除レバー３２５を下方に押圧させることにより、ゴムローラ３２８がブレーキドラム３４ａから離反させられてコードリール３４のブレーキが解除され、コードリール３４が渦巻きバネ（図示せず）のバネ力により回転させられて、電源コード３４ｂがコードリール３４に巻き取られる。尚、このようなブレーキ装置３２４には周知の構造が採用できる。   Further, when the brake presses the release lever 325 downward, the rubber roller 328 is separated from the brake drum 34a, the brake of the cord reel 34 is released, and the cord reel 34 is moved by the spring force of a spiral spring (not shown). The power cord 34b is wound around the cord reel 34 by being rotated. A known structure can be adopted for such a brake device 324.

そして、ハンドル２００がハンドル収納凹部３０ｂ内にコイルスプリング（ハンドル収納用バネ）３２３で収納されて、ガイドスリット３１９，３１９の上端がガイド突起３２０，３２０に当接した状態では、ハンドル２００の脚部２００ａがブレーキ解除レバー３２５の上端に単に当接した状態なると共に、支持軸３１８ｂが長孔３１８ａの上下方向の上端部に位置していて、ハンドル２００を更に押し下げ可能となっている。従って、ハンドル２００をハンドル収納位置から更に押し下げて、ハンドル２００の脚部２００ａでブレーキ解除レバー３２５を押し下げて、ゴムローラ３２８によるコードリール３４のブレーキを解除しても、スライダ３０２及び塵落とし部材３０４が移動することはない。この結果、ハンドル操作によるブレーキ解除によりスライダ３０２及び塵落とし部材３０４が破損するようなことは未然に防止できる。   When the handle 200 is housed in the handle housing recess 30b by a coil spring (handle housing spring) 323 and the upper ends of the guide slits 319 and 319 are in contact with the guide protrusions 320 and 320, the leg portion of the handle 200 is stored. 200a is simply in contact with the upper end of the brake release lever 325, and the support shaft 318b is positioned at the upper end in the vertical direction of the long hole 318a so that the handle 200 can be further pushed down. Therefore, even if the handle 200 is further pushed down from the handle storage position, the brake release lever 325 is pushed down by the leg portion 200a of the handle 200, and the brake of the cord reel 34 by the rubber roller 328 is released, the slider 302 and the dust drop member 304 remain. Never move. As a result, it is possible to prevent the slider 302 and the dust drop member 304 from being damaged by releasing the brake by operating the handle.

集塵容器５０は、図３に示すように、上部に形成された周回風路部５１（図４，図５参照）と、この周回風路部５１の下に形成された第１集塵室としての集塵部（第１集塵部）６０と、この集塵部６０の後部側に形成された負圧室部７０と、底蓋８０とを有している。   As shown in FIG. 3, the dust collecting container 50 includes a surrounding air passage portion 51 (see FIGS. 4 and 5) formed in an upper portion and a first dust collecting chamber formed under the surrounding air passage portion 51. As a dust collection part (first dust collection part) 60, a negative pressure chamber part 70 formed on the rear side of the dust collection part 60, and a bottom cover 80.

周回風路部５１は、図６に示すように中心部に設けた塵埃分離部（第１塵埃分離部）５２の周囲に円弧状の周回風路５３を形成したものである。周回風路５３の先端の先端開口５４は、図３に示すように蓋体４０の管部２２の接続開口２３に接合されている。周回風路５３は後端開口５５を介して集塵部６０内に連通している。   As shown in FIG. 6, the circulating air passage 51 is formed by forming an arcuate circulating air passage 53 around a dust separation portion (first dust separation portion) 52 provided at the center. The tip opening 54 at the tip of the circulating air passage 53 is joined to the connection opening 23 of the tube portion 22 of the lid 40 as shown in FIG. The circulating air passage 53 communicates with the inside of the dust collecting portion 60 through the rear end opening 55.

また、周回風路５３の途中の底部には負圧室部７０に連通する開口５７が形成され、この開口５７にはネットフィルタＦ２が張られている。塵埃分離部５２は、ほぼ裁頭円錐台状に形成されたネットフィルタＦ１で形成されている。塵埃分離５２内の底部は開口され、この開口５６を介して塵埃分離５２内と負圧室部７０とが連通している。   Further, an opening 57 communicating with the negative pressure chamber portion 70 is formed in the middle of the circulating air passage 53, and a net filter F2 is stretched on the opening 57. The dust separation part 52 is formed by a net filter F1 formed in a truncated cone shape. The bottom of the dust separator 52 is opened, and the dust separator 52 and the negative pressure chamber portion 70 communicate with each other through the opening 56.

集塵部６０の後部の隔壁６１には、負圧室部７０に連通する開口６２が形成され、隔壁６１の下部壁６１Ａには連通穴（連通開口）６３が形成されている。すなわち、開口６２の下に連通穴６３が形成されている。そして、開口６２にはネットフィルタＦ３が張られている。   An opening 62 communicating with the negative pressure chamber portion 70 is formed in the partition wall 61 at the rear of the dust collecting unit 60, and a communication hole (communication opening) 63 is formed in the lower wall 61 </ b> A of the partition wall 61. That is, a communication hole 63 is formed below the opening 62. A net filter F3 is stretched on the opening 62.

負圧室部７０の後部（図５において右側）には、図３のプリーツフィルタ体１００を着脱可能に装着する枠部７１が一体形成され、この枠部７１の後端開口７２が図３に示す本体ケース３０の前面開口（図示せず）に接合されている。   A frame portion 71 for detachably mounting the pleated filter body 100 of FIG. 3 is integrally formed at the rear portion of the negative pressure chamber portion 70 (right side in FIG. 5), and the rear end opening 72 of the frame portion 71 is formed in FIG. It is joined to the front opening (not shown) of the main body case 30 shown.

このプリーツフィルタ１００は、図１４，図１５に示したように上下に延びる山と谷からなり且つ左右方向に配列された多数のヒダ１００ａを有する。そして、上述した塵落とし部材３０４に設けた塵落とし部３０５の先端部がプリーツフィルタ１００の後面側（エア流れの下流側）に図１４に示したように係合するようになっている。   As shown in FIGS. 14 and 15, the pleated filter 100 has a number of pleats 100a made up of peaks and valleys extending vertically and arranged in the left-right direction. And the front-end | tip part of the dust drop part 305 provided in the dust drop member 304 mentioned above engages with the rear surface side (downstream side of an air flow) of the pleat filter 100 as shown in FIG.

枠部７１の下部には下部後壁部７３が形成され、この下部後壁部７３と集塵部６０の隔壁６１の下部壁６１Ａと底蓋８０とで囲まれる空間が細塵集塵部（第２集塵部）７４となっている。この細塵集塵部７４は隔壁６１の連通穴６３を介して集塵部６０内と連通するようになっている。また、枠部７１の下枠壁部７１Ａと隔壁６１の下部壁６１Ａとの間が導入開口７５となっている。   A lower rear wall portion 73 is formed at the lower portion of the frame portion 71, and a space surrounded by the lower rear wall portion 73 and the lower wall 61A of the partition wall 61 of the dust collection portion 60 and the bottom lid 80 is a fine dust collection portion ( (Second dust collecting portion) 74. The fine dust collection portion 74 communicates with the inside of the dust collection portion 60 through the communication hole 63 of the partition wall 61. An introduction opening 75 is formed between the lower frame wall portion 71 </ b> A of the frame portion 71 and the lower wall 61 </ b> A of the partition wall 61.

また、集塵部６０の隔壁６１の下部には、導入開口７５を閉塞するための開閉板（開閉蓋）７６の一端部（図３において上部）が軸支されている。この開閉板７６は一端部を中心にして回動自在となっており、電動送風機３３が駆動されていないとき、自重により隔壁６１の連通穴６３を閉塞し、細塵集塵部７４の導入開口７５は開放される。そして、電動送風機３３の駆動により負圧室部７０内が負圧になると、開閉板７６が回動して導入開口７５を閉塞（図９参照）するようになっている。   Further, one end portion (upper portion in FIG. 3) of an opening / closing plate (opening / closing lid) 76 for closing the introduction opening 75 is pivotally supported at the lower portion of the partition wall 61 of the dust collecting portion 60. The opening / closing plate 76 is rotatable about one end, and when the electric blower 33 is not driven, the communication hole 63 of the partition wall 61 is closed by its own weight, and the introduction opening of the fine dust collecting portion 74 is closed. 75 is opened. And when the inside of the negative pressure chamber part 70 becomes a negative pressure by the drive of the electric blower 33, the open / close plate 76 rotates to close the introduction opening 75 (see FIG. 9).

底蓋８０は、図３に示す軸８１を中心にして時計回りに回動可能となっており、この回動により集塵部６０および細塵集塵部７４の底部が開放されて、集塵部６０および細塵集塵部７４に溜まった塵埃を捨てることできるようになっている。
［動 作］
次に、上記のように構成される電気掃除機の動作について説明する。 The bottom cover 80 can be rotated clockwise about a shaft 81 shown in FIG. 3, and this rotation opens the bottom of the dust collecting unit 60 and the fine dust collecting unit 74, thereby collecting the dust. The dust accumulated in the portion 60 and the fine dust collecting portion 74 can be discarded.
[Operation]
Next, operation | movement of the vacuum cleaner comprised as mentioned above is demonstrated.

先ず、図２に示すように、集塵容器５０を本体ケース３０の載置部３５に載置して蓋体４０を閉じ、図１に示すように集塵ホース２１の一端を蓋体４０のホース接続口２１に接続する。   First, as shown in FIG. 2, the dust collection container 50 is placed on the placement portion 35 of the main body case 30 to close the lid 40, and one end of the dust collection hose 21 is attached to the lid 40 as shown in FIG. 1. Connect to the hose connection port 21.

この状態では、図３に示すように、集塵容器５０の先端開口５４と蓋体４０の管部２２の接続開口２３が接合されて、集塵ホース１２と集塵容器５０の周回風路部５１が接続される。   In this state, as shown in FIG. 3, the front end opening 54 of the dust collecting container 50 and the connection opening 23 of the tube part 22 of the lid body 40 are joined to each other, and the circulating air path part of the dust collecting hose 12 and the dust collecting container 50 is joined. 51 is connected.

そして、操作部１３ＡのスイッチＳを操作すると電動送風機３３が駆動される。この電動送風機３３の駆動により集塵容器５０の負圧室部７０および集塵部６０が負圧となる。この負圧は、周回風路５３，集塵ホース１２，手元操作部（手元操作パイプ），延長管（延長パイプ）１４を介して吸込口体１５の図示しない吸込室に作用する。   When the switch S of the operation unit 13A is operated, the electric blower 33 is driven. By driving the electric blower 33, the negative pressure chamber portion 70 and the dust collection portion 60 of the dust collecting container 50 become negative pressure. This negative pressure acts on a suction chamber (not shown) of the suction port body 15 via the circulating air passage 53, the dust collection hose 12, the hand operation part (hand operation pipe), and the extension pipe (extension pipe) 14.

この負圧により、図示しない清掃面の塵埃は空気と共に吸込口体１５の吸込室（図示せず）に吸い込まれる。そして、吸込口体１５の吸込室（図示せず）に吸い込まれた塵埃は、空気と共に延長管（延長パイプ）１４，手元操作部（手元操作パイプ），集塵ホース１２を介して集塵容器５０の周回風路５３内に吸い込まれる。   Due to this negative pressure, dust on the cleaning surface (not shown) is sucked into the suction chamber (not shown) of the suction port 15 together with air. The dust sucked into the suction chamber (not shown) of the suction port body 15 is collected together with air through the extension pipe (extension pipe) 14, the hand operation section (hand operation pipe), and the dust collection hose 12. The air is sucked into the 50 circulating air passages 53.

この周回風路５３に吸い込まれた空気の一部及び細塵の一部はネットフィルタＦ１及びネットフィルタＦ２を介して負圧室部７０内に流入する。一方、周回風路５３に空気と共に吸い込まれた塵埃のうち大きく重量のあるもの及び細塵の一部は、慣性力により周回風路５３に沿って流れて周回風路５３の後端開口５５を介して集塵部６０内に流入する。この集塵部６０内に流入した塵埃の一部はネットフィルタＦ３を介して負圧室部７０内に流入する。この際、塵埃のうち大きく重量のあるものは集塵部６０内に捕捉される。   Part of the air sucked into the circulating air passage 53 and part of the fine dust flow into the negative pressure chamber 70 through the net filter F1 and the net filter F2. On the other hand, dust that is heavy and heavy among the dust sucked together with the air into the circulating air passage 53 and a part of the fine dust flow along the circulating air passage 53 by the inertial force, and pass through the rear end opening 55 of the circulating air passage 53. And flows into the dust collecting section 60. Part of the dust that has flowed into the dust collecting portion 60 flows into the negative pressure chamber portion 70 via the net filter F3. At this time, large and heavy dust is trapped in the dust collecting unit 60.

そして、負圧室部７０内に流入した空気は、プリーツフィルタ１００を透過して電動送風機３３に吸い込まれて内部を冷却した後、排出されて本体ケース３０の図示しない排気口から大気に排気される。この際、負圧室部７０内に流入した細塵はプリーツフィルタ１００により捕捉される。
（プリーツフィルタ１００の除塵）
＜ハンドル１００の起立操作時＞
このような電気掃除機において、作業者がハンドル２００を掴んで掃除機本体２０をこれの重量に抗して持ち上げようとすると、このハンドル１００が図７，図８の収納位置（図１６の（イ）の位置）から図９，図１０の使用位置（図１６の（ロ）の位置）まで起立させられる。これに伴い、ハンドル２００に連動するラック３１６がリンク３１８を介して図１０の如く上方に引き上げられる。 The air that has flowed into the negative pressure chamber 70 passes through the pleated filter 100 and is sucked into the electric blower 33 to cool the inside, and then is discharged and exhausted from the exhaust port (not shown) of the main body case 30 to the atmosphere. The At this time, fine dust flowing into the negative pressure chamber portion 70 is captured by the pleated filter 100.
(Dust removal from pleated filter 100)
<During operation of the handle 100>
In such a vacuum cleaner, when an operator grasps the handle 200 and tries to lift the cleaner body 20 against its weight, the handle 100 is moved to the storage position shown in FIGS. E) from the position (b) to the use position shown in FIGS. 9 and 10 (position (b) in FIG. 16). Along with this, the rack 316 interlocked with the handle 200 is pulled upward through the link 318 as shown in FIG.

これに伴い、ピニオン３１５が回転させられ、この回転がギヤ３１４，ピニオン３１３を介してピニオン３１２を介してラック３０３に伝達され、ラック３０３を有するスライダ３０２が図７の左の位置（図１７の（イ）の位置）から図９の右の位置（図１７の（ロ）の位置）まで矢印Ａ１方向に移動（往動）させられる。   Accordingly, the pinion 315 is rotated, and this rotation is transmitted to the rack 303 through the gear 314 and the pinion 313 through the pinion 312 and the slider 302 having the rack 303 is moved to the left position in FIG. From the position (A) to the right position in FIG. 9 (position (B) in FIG. 17), it is moved (moved forward) in the direction of arrow A1.

この際、図１３，図１４のスライダ３０２の塵落とし部材３０４もスライダ３０２と一体に矢印Ａ１の方向に移動（往動）して、塵落とし部材３０４の塵落とし部３０５に設けた第１係合部３０５ａが図１４の如くプリーツフィルタ１００のヒダ１００ａに係合した後に乗り越え、ヒダ１００ａが第１係合部により強く弾かれて、プリーツフィルタ１００を振動させる。この動作は、多数のヒダ１００ａに対して順次行われ、プリーツフィルタ１００の上流側の面に付着した細塵が落とされて細塵捕集部７４に捕集される。
＜ハンドル１００の倒伏時＞
一方、掃除機本体２０を移動先まで運んで清掃面に載置し、ハンドル２００をから手を離すと、ハンドル２００はコイルスプリング３２３のバネ力により図９，図１０の使用位置（図１６の（ロ）の位置）から図７，図８の収納位置（図１６の（イ）の位置）まで降下させられる。 At this time, the dust drop member 304 of the slider 302 in FIGS. 13 and 14 also moves (forwards) together with the slider 302 in the direction of the arrow A 1, and is provided in the dust drop part 305 of the dust drop member 304. As shown in FIG. 14, the joint portion 305a gets over after engaging with the pleat 100a of the pleated filter 100, and the pleat 100a is repelled strongly by the first engaging portion to vibrate the pleated filter 100. This operation is sequentially performed on a large number of pleats 100a, and fine dust adhering to the upstream surface of the pleat filter 100 is dropped and collected by the fine dust collecting unit 74.
<When the handle 100 is lying down>
On the other hand, when the cleaner body 20 is carried to the destination and placed on the cleaning surface and the handle 200 is released from the handle 200, the handle 200 is moved to the use position shown in FIGS. (B)) to the storage position shown in FIGS. 7 and 8 (position (b) in FIG. 16).

これに伴い、ピニオン３１５が回転させられ、この回転がギヤ３１４，ピニオン３１３を介してピニオン３１２を介してラック３０３に伝達され、ラック３０３を有するスライダ３０２が図９の右の位置（図１７の（ロ）の位置）から図７の左の位置（図１７の（イ）の位置）まで矢印Ａ２方向に移動（復動）させられる。   Accordingly, the pinion 315 is rotated, and this rotation is transmitted to the rack 303 through the gear 314 and the pinion 313 through the pinion 312 and the slider 302 having the rack 303 is moved to the right position in FIG. The position is moved (returned) in the direction of arrow A2 from the position (b) to the left position in FIG. 7 (position (b) in FIG. 17).

この際、図１３，図１４のスライダ３０２の塵落とし部材３０４もスライダ３０２と一体に矢印Ａ２の方向に移動（復動）する。これに伴い、塵落とし部材３０４の塵落とし部３０５に設けた第２係合部３０５ｂがプリーツフィルタ１００のヒダ１００ａに順次係合して乗り越える際、塵落とし部材３０４は脚部３０８が支持壁３１０に当たるまで取付ボス３０６を中心に矢印Ａ３方向に回動する。これにより、第２係合部３０５ｂは第１係合部より１００ａを弱く弾いて、プリーツフィルタ１００を振動させる。この動作は、多数のヒダ１００ａに対して順次行われ、プリーツフィルタ１００の上流側の面に付着した細塵が落とされて細塵捕集部７４に捕集される。
（電源コード３４ｂの巻取操作）
この様な操作により、プリーツフィルタ１００の多数のヒダ１００ａは２つの塵落とし部材３０４，３０４の少なくとも一方により必ず弾かれて、プリーツフィルタ１００に付着した塵埃が落とされる。そして、ハンドル２００がコイルスプリング３２３のバネ力により図７，図８の収納位置（図１６の（イ）の位置）まで降下させられ、ハンドル２００がハンドル収納凹部３０ａ内にコイルスプリング（ハンドル収納用バネ）３２３で収納されると、ガイドスリット３１９，３１９の上端がガイド突起３２０，３２０に当接する。 At this time, the dust dropping member 304 of the slider 302 in FIGS. 13 and 14 also moves (returns) integrally with the slider 302 in the direction of the arrow A2. Accordingly, when the second engaging portion 305b provided in the dust removing portion 305 of the dust removing member 304 is sequentially engaged with the pleat 100a of the pleated filter 100, the leg portion 308 of the dust removing member 304 is supported by the support wall 310. It rotates in the direction of arrow A3 about the mounting boss 306 until it hits. As a result, the second engaging portion 305b repels 100a weaker than the first engaging portion, and vibrates the pleated filter 100. This operation is sequentially performed on a large number of pleats 100a, and fine dust adhering to the upstream surface of the pleat filter 100 is dropped and collected by the fine dust collecting unit 74.
(Winding operation of the power cord 34b)
By such an operation, a large number of pleats 100a of the pleat filter 100 are surely bounced by at least one of the two dust drop members 304 and 304, and dust attached to the pleat filter 100 is dropped. The handle 200 is lowered by the spring force of the coil spring 323 to the storage position shown in FIGS. 7 and 8 (position (A) in FIG. 16), and the handle 200 is coiled into the handle storage recess 30a (for storing the handle). When stored in the spring 323, the upper ends of the guide slits 319 and 319 come into contact with the guide protrusions 320 and 320.

この状態では、ハンドル２００の脚部２００ａが図１１状態から図１２の如くブレーキ解除レバー３２５の上端にハンドル２００の自重のみにより単に当接した状態（図１６の（イ）の位置の状態）になると共に、リンク３１８の支持軸３１８ｂが長孔３１８ａの上下方向の上端部に位置していて、ハンドル２００を更に押し下げ可能となっている。   In this state, the leg portion 200a of the handle 200 is changed from the state shown in FIG. 11 to the state where the leg 200a is simply in contact with the upper end of the brake release lever 325 only by its own weight as shown in FIG. At the same time, the support shaft 318b of the link 318 is positioned at the upper end in the vertical direction of the long hole 318a, and the handle 200 can be further pushed down.

しかし、この状態では、ガイドスリット３１９，３１９の上端がガイド突起３２０，３２０に当接しているので、ハンドル２００を更に押し下げてもラック３１６は降下せず、スライダ３０２は図１７の（ロ）の位置より矢印Ａ２方向に更に移動して、プリーツフィルタ１００のフィルタ枠１００ｂに当たるようなことはない。   However, in this state, since the upper ends of the guide slits 319 and 319 are in contact with the guide protrusions 320 and 320, the rack 316 does not descend even if the handle 200 is further pushed down, and the slider 302 is shown in FIG. There is no further movement in the direction of the arrow A2 from the position and hitting the filter frame 100b of the pleated filter 100.

この状態からハンドル２００を更に押し下げて、ハンドル２００の脚部２００ａでブレーキ解除レバー３２５を押し下げて、ゴムローラ３２８にをブレーキドラム３４ａから上方に離反させると、ゴムローラ３２８によるコードリール３４のブレーキが解除され、電源コード３４ｂがコードリール３４に図示しない渦巻きバネのバネ力で巻き取られることになる。   When the handle 200 is further pushed down from this state and the brake release lever 325 is pushed down by the leg portion 200a of the handle 200 and the rubber roller 328 is separated upward from the brake drum 34a, the brake of the cord reel 34 by the rubber roller 328 is released. The power cord 34b is wound around the cord reel 34 by the spring force of a spiral spring (not shown).

従って、ハンドル２００をハンドル収納位置から更に押し下げて、ハンドル２００の脚部２００ａでブレーキ解除レバー３２５を押し下げて、ゴムローラ３２８によるコードリール３４のブレーキを解除しても、スライダ３０２及び塵落とし部材３０４が移動することはない。この結果、ハンドル操作によるブレーキ解除によりスライダ３０２及び塵落とし部材３０４が破損するようなことは未然に防止できる。   Therefore, even if the handle 200 is further pushed down from the handle storage position, the brake release lever 325 is pushed down by the leg portion 200a of the handle 200, and the brake of the cord reel 34 by the rubber roller 328 is released, the slider 302 and the dust drop member 304 remain. Never move. As a result, it is possible to prevent the slider 302 and the dust drop member 304 from being damaged by releasing the brake by operating the handle.

以上説明したように、この発明の実施の形態の電気掃除機は、集塵室（集塵部６０）及び前記集塵室（集塵部６０）に吸込負圧を作用させる電動送風機３３が設けられた掃除機本体２０と、前記電動送風機３３の負圧により空気と共に前記集塵室（集塵部６０，７４）に吸引した塵埃を分離するフィルタ（Ｆ１〜Ｆ３，１００）と、前記フィルタ（プリーツフィルタ１００）に振動を付与して前記フィルタ（プリーツフィルタ１００）の上流側の面に付着した塵埃を落とす除塵手段（塵落とし部材３０４）を備えている。また、この電気掃除機は、前記掃除機本体２０の上面の収納位置と上方に持ち上げた使用位置との間で上下動可能に前記掃除機本体２０に取り付けられた本体持ち運び用のハンドル２００と、前記ハンドル２００を収納位置側に付勢する収納用バネ（コイルスプリング３２３）と、前記ハンドル２００の上下動に連動して前記除塵手段（塵落とし部材３０４）を駆動させる動力伝達手段３００Ａを設けている。   As described above, the electric vacuum cleaner according to the embodiment of the present invention includes the dust collection chamber (dust collection unit 60) and the electric blower 33 that applies the suction negative pressure to the dust collection chamber (dust collection unit 60).

Further, when the handle is returned to the storage position by the spring force of the storage spring (coil spring 323), the handle is generated between the dust removing means and the filter when the handle is moved down to the storage position by the storage spring. Since the second load is made smaller than the first load and the dust removing means is moved back only by the spring force of the storage spring (coil spring 323), the spring force of the storage spring (coil spring 323) Can be removed by applying vibration to the filter by the dust removing means (dust removing member 304).

また、この発明の実施の形態の電気掃除機において、前記フィルタは上下に延びる山と谷を有するヒダが左右方向に多数配列されたプリーツフィルタであり、前記除塵手段は前記ハンドルの上下動に連動して前記ヒダの配列方向に往復動可能に設けられていると共に、前記ハンドルを手動により上方へ移動させる際に前記ハンドルに連動して往動して前記多数のヒダを順次弾く第１ガイド部（第１係合部３０５ａ）が前記除塵手段（塵落とし部材３０４）に設けられ、前記ハンドルを前記収納用バネにより下動させる際に前記ハンドルに連動して前記多数のヒダを前記往動よりも順次弱く弾く第２ガイド部（第２係合部３０５ｂ）が前記除塵手段（塵落とし部材３０４）に設けられている。   In the vacuum cleaner according to the embodiment of the present invention, the filter is a pleated filter in which pleats having peaks and valleys extending vertically are arranged in the left-right direction, and the dust removing means is interlocked with the vertical movement of the handle. The first guide portion is provided so as to be capable of reciprocating in the fold arrangement direction, and moves forward in conjunction with the handle when the handle is manually moved upward to sequentially repel the pleats. (First engaging portion 305a) is provided in the dust removing means (dust removing member 304), and when the handle is moved downward by the storage spring, the plurality of folds are moved from the forward movement in conjunction with the handle. In addition, a second guide portion (second engaging portion 305b) that sequentially weakens is provided in the dust removing means (dust removing member 304).

この構成によれば、ハンドルを持ち上げるときの掃除機本体の重量の反力を利用して、除塵手段を往動させることができるので、ハンドルを手動により上方へ移動させる際に除塵手段と前記フィルタとの間に発生する第１の負荷を大きくして、除塵手段（塵落とし部材３０４）によりフィルタへの振動付与力を大きくできる。また、ハンドルを収納用バネ（コイルスプリング３２３）のバネ力で収納位置まで戻すときには、前記ハンドルを前記収納用バネにより収納位置に下動させる際に前記除塵手段と前記フィルタとの間に発生する第２の負荷を第１の負荷よりも小さくして、収納用バネ（コイルスプリング３２３）のバネ力のみで除塵手段を復動させるようになるので、収納用バネ（コイルスプリング３２３）のバネ力が弱くても除塵手段（塵落とし部材３０４）によりフィルタへ振動を付与して除塵できる。尚、第２ガイド部（第２係合部３０５ｂ）としては、傾斜面の外に、Ｃ面や、Ｒ面を用いることができる。この場合、除塵手段（塵落とし部材３０４）が収納用バネ（コイルスプリング３２３）のバネ力により復動する際に移動方向（復動方向）と反対方向に回動しても良いし、回動しなくても良い。   According to this configuration, since the dust removing means can be moved forward by utilizing the reaction force of the weight of the cleaner body when lifting the handle, the dust removing means and the filter can be moved when the handle is moved manually. The first load generated between the first and second filters can be increased, and the vibration imparting force to the filter can be increased by the dust removing means (dust removing member 304). Further, when the handle is returned to the storage position by the spring force of the storage spring (coil spring 323), the handle is generated between the dust removing means and the filter when the handle is moved down to the storage position by the storage spring. Since the second load is made smaller than the first load and the dust removing means is moved back only by the spring force of the storage spring (coil spring 323), the spring force of the storage spring (coil spring 323) Can be removed by applying vibration to the filter by the dust removing means (dust removing member 304). In addition, as a 2nd guide part (2nd engaging part 305b), C surface and R surface can be used besides an inclined surface. In this case, when the dust removing means (dust removing member 304) moves backward by the spring force of the storage spring (coil spring 323), it may rotate in the direction opposite to the moving direction (returning direction) or turn. You don't have to.

また、この発明の実施の形態の電気掃除機において、前記フィルタは上下に延びる山と谷を有するヒダが左右方向に多数配列されたプリーツフィルタ１００であり、前記除塵手段（塵落とし部材）は前記ハンドル２００の上下動に連動して前記ヒダ１００ａの配列方向に往復動可能に設けられていると共に、前記除塵手段（塵落とし部材３０４）は前記ハンドル２００を前記収納用バネ（コイルスプリング３２３）により下動させる際に前記ハンドル２００に連動して復動し且つ復動方向とは反対方向に回動可能に設けられている。   In the vacuum cleaner according to the embodiment of the present invention, the filter is a pleated filter 100 in which a plurality of folds having peaks and valleys extending in the vertical direction are arranged in the left-right direction, and the dust removing means (dust removing member) is the The handle 200 is provided so as to reciprocate in the direction in which the folds 100a are arranged in conjunction with the vertical movement of the handle 200, and the dust removing means (dust removing member 304) moves the handle 200 to the storage spring (coil spring 323). When it is moved downward, it is interlocked with the handle 200 and can be rotated in the direction opposite to the backward movement direction.

この構成によれば、除塵手段（塵落とし部材３０４）が収納用バネ（コイルスプリング３２３）のバネ力により復動する際に移動方向（復動方向）と反対方向に回動するので、この回動によりハンドルを収納用バネ（コイルスプリング３２３）のバネ力で収納位置まで戻すときには、前記ハンドルを前記収納用バネにより収納位置に下動させる際に前記除塵手段と前記フィルタとの間に発生する第２の負荷を第１の負荷よりも小さくできる。これにより、収納用バネ（コイルスプリング３２３）のバネ力のみで除塵手段を復動させるようになるので、収納用バネ（コイルスプリング３２３）のバネ力が弱くても除塵手段（塵落とし部材３０４）によりフィルタ（１００）へ振動を付与して除塵できる。   According to this configuration, when the dust removing means (dust removing member 304) moves backward by the spring force of the storage spring (coil spring 323), it rotates in the direction opposite to the moving direction (returning direction). When the handle is returned to the storage position by the spring force of the storage spring (coil spring 323) by the movement, it is generated between the dust removing means and the filter when the handle is moved down to the storage position by the storage spring. The second load can be smaller than the first load. As a result, the dust removal means can be moved back only by the spring force of the storage spring (coil spring 323), so even if the spring force of the storage spring (coil spring 323) is weak, the dust removal means (dust removal member 304). By applying vibration to the filter (100), dust can be removed.
