【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.

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

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
