【考案の詳細な説明】
本考案は電気掃除機の除塵装置に係り、ごみ処理時の使
用性の向上を図ることを目的とする。[Detailed Description of the Invention] The present invention relates to a dust removal device for a vacuum cleaner, and its purpose is to improve usability during garbage disposal.
近年、電気掃除機においては、手を汚さず衛生的にごみ
捨てを行えるものが要求されるようになり、この要求に
応えるため、第1図に示すような掃除機が考えられてい
る。In recent years, there has been a demand for vacuum cleaners that can be used to dispose of garbage hygienically without soiling hands, and in order to meet this demand, a vacuum cleaner as shown in FIG. 1 has been devised.
すなわち、電気掃除機本体101に着脱自在にした集塵
箱102の上方を開口しこの開口部を閉蓋するように吸
気口部103を有する略円筒状の一次フィルター104
と二次フィルター105よりなるフィルター装置を位置
させ、上記二次フィルター105直下の一次フィルター
104内に略円板状で細塵排出装置106を有する細塵
受け107を上下摺動自在に配設している。That is, a substantially cylindrical primary filter 104 has an opening above a dust collection box 102 which is detachably attached to a vacuum cleaner main body 101, and has an air intake port 103 so as to close this opening.
A filter device consisting of a secondary filter 105 is positioned, and a fine dust receiver 107 having a substantially disc shape and having a fine dust discharge device 106 is arranged in the primary filter 104 directly below the secondary filter 105 so as to be vertically slidable. ing.
そして上記細塵受け107には押し出し軸108を設け
、この押し出し軸108の先端に押ボタン109を設け
て、本体101の外部より前記細塵受け107を上下動
させ、ごみ捨ての時は一次フィルター104内に溜まっ
た塵埃を集塵箱102内へ移動させて押し固め、集塵箱
102を本体101より外してごみを捨てる方式のもの
である。The fine dust receptacle 107 is provided with an extrusion shaft 108, and a push button 109 is provided at the tip of the extrusion shaft 108 to move the fine dust receptacle 107 up and down from the outside of the main body 101. When disposing of garbage, the primary filter 104 is moved. The dust collected inside is moved into the dust collection box 102 and compacted, and the dust collection box 102 is removed from the main body 101 and the dust is thrown away.
この構成の場合、ごみ捨てをした後、細塵受け107を
上方に引き上げるのを忘れて、電気掃除機が使用される
と、塵埃は吸気口部103を通ってすべて二次フィルタ
ー105側へ流入し、早期に吸込性能が低下してしまう
と同時に、二次フィルター105は細塵捕獲専用のため
、フィルター装置を分解して付着した粗悪を取り除いて
やらねば次からの使用ができないという問題が発生した
。In this configuration, if you forget to pull up the dust receptacle 107 and use a vacuum cleaner after disposing of the garbage, all the dust will flow into the secondary filter 105 through the intake port 103. At the same time, the suction performance deteriorated early, and at the same time, since the secondary filter 105 was only used to capture fine dust, there was a problem that the filter device could not be used again unless the filter device was disassembled and the adhering dirt was removed. .
これを解決するにはバネ等で細塵受け107を上方へ常
に付勢すればよいわけであるが、上記押し出し軸108
の外側にバネを取りつけた場合、エアーダイトを十分に
しなければ塵埃を含んだ空気流が流れ細塵がバネ等に付
着し、摺動抵抗の増大、バネのきしみ音の問題が起ると
同時に、フィルター装置の組立が複雑になり、組立コス
ト面でも問題が生じ、また一般消費者がフィルター装置
の掃除のために、同フィルター装置を分解する際その分
解組立が難しくなるという問題も派生する。To solve this problem, the fine dust receiver 107 can be constantly urged upward with a spring or the like, but the push-out shaft 108
When a spring is attached to the outside of the spring, if air-dite is not sufficient, airflow containing dust will flow and fine dust will adhere to the spring, etc., which will increase sliding resistance and cause the problem of spring squeaking. The assembly of the filter device becomes complicated, which causes problems in terms of assembly cost, and also causes problems in that it becomes difficult for general consumers to disassemble and reassemble the filter device for cleaning.

塵落歯車61が回転すると振動板63がろ材17に振動
与えて二次フィルター16に付着している細塵を落下さ
せる。When the dust removal gear 61 rotates, the diaphragm 63 vibrates the filter medium 17 to cause fine dust adhering to the secondary filter 16 to fall.
そしてこの細塵は細塵受34で受は止められる。This fine dust is then stopped by a fine dust receiver 34.
また塵落歯車61の伝動爪62と細塵受板35の伝動爪
37とは係合しているので、上記塵落歯車61が回転す
ると、細塵受板35に固着している押圧板30も回転す
る。Further, since the transmission pawl 62 of the dust removal gear 61 and the transmission pawl 37 of the fine dust receiving plate 35 are engaged with each other, when the dust removal gear 61 rotates, the pressing plate 30 fixed to the fine dust receiving plate 35 It also rotates.
このように押圧板30が回転することにより細塵受34
上に溜った細塵は細塵集塵板44によって集められ、細
塵取入口36に投入される。By rotating the press plate 30 in this way, the fine dust receiver 34
The fine dust accumulated on the top is collected by a fine dust collection plate 44 and introduced into the fine dust intake port 36.
細塵弁40の細塵溜41は細塵取入口36より流入した
細塵を溜めて、押圧板30がさらに回転して細塵溜41
と細塵排出口32とが重なった時に同細塵を集塵箱24
側へ排出する。The fine dust reservoir 41 of the fine dust valve 40 collects the fine dust that has flowed in from the fine dust intake port 36, and the press plate 30 further rotates to collect the fine dust.
When the fine dust outlet 32 overlaps with the fine dust outlet 32, the same fine dust is removed from the dust collection box 24.
Drain to the side.
次に集塵箱24内の塵埃を捨て去る時には、押ボタン4

で、一次フィルター18の綱部20は粗塵、特に綿ごみ
の付着のない清潔な状態になる。Next, when you want to throw away the dust in the dust collection box 24, press the pushbutton 4.
When 9 is pressed, the pressing plate 30 moves toward the dust collection box 24, and its sliding wall 33 scrapes off the coarse dust attached to the primary filter 18, compresses it, and presses it into the dust collecting part 25, so that the primary filter The rope section 20 of No. 18 is in a clean state free from adhesion of coarse dust, especially cotton waste.
押ボタン49をさらに押し込むと尾錠操作部59が傾斜
部60を押して尾錠45を尾錠ばね46の力に抗して移
動させるため、尾錠引掛部48より尾錠係止部47が外
れて係止が解除される。When the push button 49 is pushed further, the buckle operating part 59 pushes the inclined part 60 and moves the buckle 45 against the force of the buckle spring 46, so the buckle locking part 47 comes off from the buckle hooking part 48 and the lock is released. be done.
押ボタン49が押せなくなる所まで押した後、押すのを
やめると、本体蓋5は蓋ばねの付勢力で蓋軸6を回転中
心として上方へ開離する。When the push button 49 is pressed until it can no longer be pressed and then stopped, the main body lid 5 opens upwardly around the lid shaft 6 due to the biasing force of the lid spring.
ここで、第3図に示すように集塵箱24を本体から引き
出し集塵袋29の口をひも等で結んで捨ればよく、手を
汚すことなく衛生的にごみ捨てが行える。Here, as shown in FIG. 3, the dust collection box 24 can be pulled out from the main body, the opening of the dust collection bag 29 tied with a string, etc., and thrown away, and the garbage can be disposed of hygienically without getting the hands dirty.
また解放後押ボタン49は固定板50と一体に形成した

力を受けているため、押圧板軸42及び押圧板30とと
もに必ず上方へ移動して、元の位置に戻り、よって、本
体蓋5を閉めて再び塵埃を吸引しても塵埃が二次フィル
ター16側へ流入することを防止する。Further, after release, the push button 49 receives a biasing force from the push button spring 55 interposed between the fixed plate 50 and the spring seat 54 formed integrally with it, so that it always moves upward together with the press plate shaft 42 and the press plate 30. It moves and returns to its original position, thus preventing dust from flowing into the secondary filter 16 side even if the main body lid 5 is closed and dust is sucked again.
次にフィルター装置の分解の際、まず本体蓋5を開け、
次に押ボタン係止部57を押して係止孔58より外し、
押ボタン49及び押ボタンばね55を押圧板軸42から
分離する。Next, when disassembling the filter device, first open the main body lid 5,
Next, press the push button locking part 57 to remove it from the locking hole 58,
The push button 49 and push button spring 55 are separated from the push plate shaft 42.
その後押圧板軸42及び押圧板30を下方へ移動し、次
いで一次フィルター18の係止部22をフィルター外枠
10の引掛孔21から外して下方へ引き抜き、最後に二
次フィルター16を下方へ引き抜けばよく、簡単にフィ
ルター装置の分解が行える。After that, the press plate shaft 42 and the press plate 30 are moved downward, and then the locking part 22 of the primary filter 18 is removed from the hook hole 21 of the filter outer frame 10 and pulled out downward, and finally the secondary filter 16 is pulled downward. All you have to do is pull it out, and the filter device can be easily disassembled.
また組立は、上記分解方法を逆にすればよい。Also, for assembly, the above disassembly method may be reversed.
このように本考案によれば円筒状の一次フィルター内を
上下に摺動する細塵受けを常にばねで上方へ付勢するこ

ことができる。In this way, according to the present invention, the fine dust tray that slides up and down inside the cylindrical primary filter is always urged upward by the spring, so that it is possible to use the vacuum cleaner without forgetting to pull the fine dust tray upward. It can prevent misuse such as driving, and
By installing the spring inside the extrusion shaft through which intake air does not flow, fine dust etc. do not adhere to the spring, and it is possible to prevent an increase in sliding resistance when pushing the extrusion shaft and prevent the squeaking sound of the spring.
