Description
【考案の詳細な説明】 本考案は電気掃除機の除塵装置に係るものである。[Detailed explanation of the idea] The present invention relates to a dust removal device for a vacuum cleaner.
従来の電気掃除機においては、塵埃を捕獲するフィルタ
ーの前にプレフィルタ−を配設して、粗塵を捕獲するよ
うにしているが、このプレフィルタ−には一般に付着塵
埃を除去する手段を設けてないのが普通である。In conventional vacuum cleaners, a pre-filter is placed in front of the filter to capture coarse dust, but this pre-filter generally has a means for removing attached dust. It is normal that it is not provided.
従って上記プレフィルタ−に捕獲された粗塵が圧縮状態
で同プレフィルタ−面上に付着し、通気抵抗が増加して
吸塵能力が低下し、股座容器からフィルター装置をはず
して上記プレフィルタ−面に付着した塵埃を取り落さな
くてはならなかった。Therefore, the coarse dust captured by the pre-filter adheres to the surface of the pre-filter in a compressed state, increasing the ventilation resistance and reducing the dust suction ability. I had to remove the dust that had stuck to the surface.
この問題解消のため前記プレフィルタ−を回転させて股
座部に溜った塵埃との相対運動によってプレフィルタ−

レフィルタ−に付着した塵埃をこすり落すことができる
が、股座部に少ししか塵埃がたまっていない時はこの効
果が見られず、プレフィルタ−面に塵埃が付着したまま
であった。In order to solve this problem, the pre-filter is rotated and the pre-filter is moved by relative movement with the dust accumulated in the crotch seat.
In this case, if there is a lot of dust on the crotch seat, this dust can be used to scrub off the dust attached to the pre-filter, but if there is a lot of dust on the crotch seat, This effect was not observed when only a small amount of dust had accumulated, and the dust remained attached to the pre-filter surface.
本考案は股座部の塵埃の多少にかかわらずプレフィルタ
−面に付着した塵埃を取り除き、上記煩雑な廃塵作業を

を提供するもので、以下図面にもとづきその一実施例を
説明する。The present invention provides a dust removal device that removes dust attached to the pre-filter surface regardless of the amount of dust on the crotch seat, eliminates the above-mentioned complicated dust removal work, and maintains high dust suction ability over a long period of time. An embodiment of the present invention will be described below based on the drawings.

体13とを備えている。In the figure, 1 is the vacuum cleaner main body (hereinafter referred to as the main body);
2 is an electric blower built into the main body 1; 3 is a rear wheel; 4 is a front wheel; 5 is a crotch seat box that has a crotch seat portion 5a and is connected to the main body 1; 5' is a hose (not shown) Connection port for connecting 6
Reference numeral denotes a handle for transporting the crotch seat box 5, 7 a buckle for attaching and detaching the crotch seat box 5 from the main body 1, and 8 a support frame for supporting the tightening rubber 9 for tightening the crotch seat box 5 and the main body 1. The support frame 8 includes a bearing 8' that supports a rotating shaft 11 formed integrally with the frame 10' at the front of the main filter 10, and a bearing 8' that supports the main filter 10.
A dust removing body 13 is provided to repel one end of a diaphragm 12 inserted into a wall of 10.

A large pulley 15 attached to the other end of the main body 1 is a small pulley that engages with the large pulley 14, and also has a claw portion 15' that engages with a clutch plate 16 on the main body 1 side.
17はコードリール(図示せず)の回転を伝える連動軸
である。17 is an interlocking shaft that transmits the rotation of a cord reel (not shown).
18はゴミタイト用パッキングで、主フイルタ−10の
後部の枠体10″より突出するリブ10 aと前記支持
枠8との間に挿入され、気密を保持している。Reference numeral 18 denotes a dust-tight packing, which is inserted between the supporting frame 8 and a rib 10a protruding from the frame 10'' at the rear of the main filter 10 to maintain airtightness.
19はプレフィルタ−で、粗塵と細塵とを分離する。19 is a pre-filter that separates coarse dust from fine dust.
このプレフィルタ−19の外周には、プレフィルタ−枠
体20の内周に対し、回転自在にタイトするバッキング
21が嵌着されている。A backing 21 that is rotatably tight to the inner circumference of the pre-filter frame 20 is fitted onto the outer circumference of the pre-filter 19 .
そして上記プレフィルタ−19は前記主フイルタ−10
の枠体10′に固定され、同主フイルタ−10と一体に
回転する。The pre-filter 19 is the main filter 10.
The main filter 10 is fixed to the frame 10' and rotates together with the main filter 10.
22は前記プレフィルタ−19の前面にほぼ当接する股
座箱5の一部よりなる凸部で゛ある。Reference numeral 22 denotes a convex portion made of a part of the crotch box 5 that substantially contacts the front surface of the pre-filter 19.
以上の構成において、コードを引き出すと、コードリー
ルの回転が連動軸17を通じて大プーリ−14に伝えら
れ、主フイルタ−10が回転し、同時にブレフィルター
19も回転する。In the above configuration, when the cord is pulled out, the rotation of the cord reel is transmitted to the large pulley 14 through the interlocking shaft 17, the main filter 10 rotates, and the blur filter 19 also rotates at the same time.
これによりブレフィルター19に付着し、同プレフィル

対運動によって同塵埃自体でも取り除かれるものである
。As a result, the coarse dust that adheres to the blur filter 19 and increases the ventilation resistance of the pre-filter 19 is removed by the protrusion 22 that protrudes from a part of the crotch box when the amount of dust in the crotch compartment is small. Moreover, when the amount of dust increases, the dust itself is removed by the relative movement with this dust.
同時に主フイルタ−10の全周に付着している細塵も除
塵体13により主フイルタ−10の襞に挿入された振動
板12をたたき、主フイルタ−10から細塵を離脱させ
る。At the same time, the fine dust attached to the entire circumference of the main filter 10 is also removed from the main filter 10 by hitting the diaphragm 12 inserted into the folds of the main filter 10 by the dust remover 13.
このように本考案によれば、プレフィルタ−を回転させ
、股座箱の一部より上記プレフィルタ−にほぼ当接する
よう凸部を設けているので、股座箱内のごみの量が少な
い場合でもプレフィルタ−面に付着した粗塵はプレフィ
ルタ−と一緒に回転し、上記凸部により前記プレフィル
タ−より取り除かれる。As described above, according to the present invention, the pre-filter is rotated and the convex portion is provided so that it almost contacts the pre-filter from a part of the crotch box, so the amount of dust in the crotch box is reduced. Even in this case, coarse dust adhering to the pre-filter surface rotates together with the pre-filter and is removed from the pre-filter by the convex portion.
この凸部により取り除かれた粗塵は一時的に凸部の近傍
に溜まり、その後次第に同凸部より互いに絡み合った状
態ではみ出すため、この粗塵により前記プレフィルタ−
表面に付着した粗塵はこすり取られるようにして除去さ
れる。The coarse dust removed by the convex part temporarily accumulates near the convex part, and then gradually protrudes from the convex part in an intertwined state.
Coarse dust adhering to the surface is removed by being scraped off.
そして上記凸部はプレフィルタ−の中心までは必要なく
、粗塵自身の絡みにより成長した塵埃が除塵に寄与する
ため、かなり低いもので十分となり、第1図、第5図に
示されるように股座箱把手の取付座や、第7図に示され
るような把手の凹部により前記凸部を形成することがで
き、特別にリブや突起を設ける必要がない。The convex part does not need to extend all the way to the center of the pre-filter, and since the dust that grows due to the entanglement of the coarse dust itself contributes to dust removal, it is sufficient to have a fairly low convex part, as shown in Figures 1 and 5. The convex portion can be formed by the mounting seat of the seat box handle or the concave portion of the handle as shown in FIG. 7, and there is no need to provide any special ribs or protrusions.
第8図は股座箱のデザイン上の凹部を利用したものであ
る。Fig. 8 shows a design that utilizes the concave part in the design of the crotch seat box.
このようにプレフィルタ−面は除塵の都度きれいにされ
るため、股座量と吸塵力(吸塵風量)の関係は第9図に
示されるように従来のものと比較し股座量が多くなって
も吸塵風量の低下が少なく、長期にわたって強い吸塵力
が得られるものである。Since the pre-filter surface is cleaned each time dust is removed in this way, the relationship between the amount of crotch and the dust suction power (air volume) is as shown in Figure 9, where the amount of crotch is larger than that of the conventional filter. Also, there is little reduction in dust suction air volume, and strong dust suction power can be obtained over a long period of time.
またごみの量の多少にかかわらずプレフィルタ−表面の
粗塵が取り除かれるためプレフィルタ−の面積が少なく
てすみ、従来前面のみならず側面にまで設けていたもの
が前面だけで十分となり、プレフィルタ−の製造が容易
になる。In addition, since coarse dust on the surface of the pre-filter is removed regardless of the amount of dust, the area of the pre-filter is reduced, and instead of the conventional one that was provided not only on the front but also on the side, the front is now sufficient. Manufacture of the filter becomes easier.
