Description

【0001】
【発明の属する技術分野】
本発明は電気掃除機に関する。さらに詳しくは、サイクロン部におけるごみの分離効果を向上させるとともに分離されたごみを集塵部に捕集する効果を向上させた電気掃除機に関する。
【0002】
【従来の技術】
従来より、図11〜12に示されるように、電動送風機51および電動送風機51の吸気側51aに接続されたサイクロン集塵器52を備え、サイクロン集塵器52が仕切板60によって仕切られたサイクロン部53および集塵部54を有するサイクロン式の電気掃除機が提案されている。このようなサイクロン方式の電気掃除機では、サイクロン部において旋回流により塵埃と空気とを分離し、分離された塵埃を集塵部54に捕集し、浄化された空気は中筒55を通してサイクロン集塵器52から外部へ排気される。
【0003】
中筒55における空気の流れは、具体的には、中筒55の開口55a、フィルタ56、フィルタ58、第2サイクロン中筒57の開口57a、中筒57を経て円筒状フィルタ59の順に空気が流れるようになっている。
【0004】
【特許文献1】
特願2001−381916号(段落番号[0008]〜[0009]、図2および図4)
【0005】
【発明が解決しようとする課題】
しかし、従来のサイクロン式の電気掃除機では、サイクロン部53から集塵部54への空気の流れが実質的にほとんどないため、サイクロン部53で分離された塵埃が集塵部54に捕集されないで中筒55のフィルタ56に貼り付くことがある。サイクロン部53は、砂などの比重の重い物を分離するの場合にはその性能を充分に発揮することができるが、比重が軽いごみで、とくに髪の毛のような長いごみに対する分離効果がわるいため、髪の毛などの長尺軽量のごみが中筒55のフィルタ56に巻きついたり、さらにはサイクロン部53と集塵部54とを隔てる傘状の仕切板60とサイクロン集塵器52の内壁とのあいだで塵埃が詰まることがある。
【0006】
本発明はかかる問題を解消するためになされたものであり、サイクロン部におけるごみの分離効果を向上させるとともに分離されたごみを集塵部に捕集する効果を向上させた電気掃除機を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明の電気掃除機は、電動送風機および該電動送風機の吸気側に接続されたサイクロン集塵器を備え、該サイクロン集塵器内部には、塵埃を空気と分離するサイクロン部と集塵部とが仕切板によって隔てられた電気掃除機であって、前記サイクロン集塵器が、前記サイクロン部内部で発生する旋回流の回転軸がほぼ水平方向に延びるように横置きに配設され、前記サイクロン部には、前記仕切板の略中心部に導入口を形成し、該導入口には、前記サイクロン部の旋回流によって浄化された空気をさらに浄化する1次フィルタを配設し、前記集塵部に設けた開口を電動送風機に連通してサイクロン部から集塵部への空気の流れを発生させ、前記開口に前記サイクロン部から集塵部に塵埃と共に入り込んだ空気が通過する際に、通過する空気によって集塵部内の塵埃を圧縮する1次フィルタを配設し、前記導入口の1次フィルタを通過した空気と前記集塵部の1次フィルタを通過した空気とを濾過する2次フィルタを前記サイクロン集塵器に配設し、前記2次フィルタで濾過された空気が前記電動送風機を通過して外部へ排気されるよう構成したことを特徴とする。
【0010】
【発明の実施の形態】
つぎに図面を参照しながら本発明の電気掃除機をさらに詳細に説明する。図1は本発明の電気掃除機の一実施の形態を示す断面説明図、図2は図1のサイクロン集塵器の断面説明図、図3は図2のサイクロン集塵器のIII−III線断面図、図4は図2のサイクロン集塵器のIV−IV線断面図、図5は本発明の他の実施の形態の電気掃除機におけるサイクロン集塵器の断面説明図、図6は図5のサイクロン集塵器のVI−VI線断面図、図7は本発明のさらに他の実施の形態の電気掃除機におけるサイクロン集塵器の断面説明図、図8は図7のサイクロン集塵器の矢視A図、図9は図7のサイクロン集塵器の比較例であるリブのない集塵器の断面説明図および図10は図9の集塵器のごみが絡み付いた部分の拡大図である。
【0011】
図1〜4に示される電気掃除機は、上面に取っ手3が設けられた掃除機の上ケース1と下面に移動用前車輪4および後車輪5が設けられた掃除機の下ケース2とからなる筐体内部に、電池6、下ケース2より直立せしめた壁と緩衝体8を介在して設置されたファンとモータとからなる電動送風機7、およびパッキン14を介在して着脱自在に設けられたサイクロン集塵器9を収納したものである。なお、サイクロン集塵器9は、掃除機本体と一体形成してもよい。
【0012】
サイクロン集塵器9は、サイクロン部9a内部で発生する旋回流の回転軸がほぼ水平方向に延びるように横置きに配置されている。すなわち、サイクロン集塵器9内部には、傘状の仕切板11aをもつ中筒11が水平方向に取り付けられている。この仕切板11によって、サイクロン集塵器9の内部空間は、塵埃を空気と分離するサイクロン部9aおよび集塵部9bの2つの空間に分けられる。
【0013】
このように、サイクロン集塵器9を横置きに配置することにより、吸気口16および排気口10aをほぼ直線的に、すなわち旋回流の回転軸とほぼ平行に配置することができる。それにより、排気口10aを電動送風機7の吸気側7aに直接連結することができるため、流路が非常に簡単になり、風量および仕事率の低下を抑えることができる。また、掃除機の外径寸法も大幅に小さくすることができる。
【0014】
さらに、サイクロン集塵器9には、3つのフィルタ、すなわち1次メッシュフィルタ12、18および2次フィルタ13が配設されている。サイクロン集塵器9の底面には、複数の開口9cが放射状に形成され、開口9cには1次メッシュフィルタ18が配設されている。このように1次メッシュフィルタ18をもつ開口9cを介して、サイクロン集塵器9が電動送風機8に連通し、サイクロン部9aから集塵部9bへの空気の流れを発生させることができる。
【0015】
1次メッシュフィルタ12は、中筒11上部の導入口11bに配設され、サイクロン部9a内部で浄化された空気をろ過することができる。1次メッシュフィルタ12としては、本発明ではとくに限定されるものではないが、たとえば直径1mm程度の開口を多数有する合成樹脂シートを採用することができる。また、合成樹脂シートの代わりにパンチングメタルなども採用することができる。さらには、中筒11の上部を構成する部材そのものに直径1mm程度の開口を多数形成し、この部分を1次メッシュフィルタとすることもできる。
【0016】
サイクロン集塵器9底面の複数の開口9cに設けられた1次メッシュフィルタ18は、本発明ではとくに限定されるものではないが、たとえば、2次フィルタ13へのごみの侵入を抑えるために前記1次メッシュフィルタ12より小さい口径のメッシュ、たとえばメッシュの大きさが直径100〜250μm程度のフィルタが採用される。また、このメッシュの開口率は、50〜70%程度であるのが好ましい。
【0017】
なお、本実施の形態では開口9cに1次メッシュフィルタ18が設けられている例が示されているが、本発明はこれに限定されるものではなく、メッシュフィルタでなく他のフィルタでもよい。
【0018】
さらに、2次フィルタ13は、フィルタの機能を有するものであれば本発明においてとくに限定されるものではないが、たとえばウレタンフォーム製フィルタ、好ましくは密度70〜90Kg/m程度のイノアック・コーポレーション製の「モルトフィルタ(商品名)」などを採用することができる。
【0019】
さらに、サイクロン集塵器9の下流側端部には、2次フィルタ13の周辺部を押えるためにフィルタの蓋10が取り付けられている。蓋10の中央部には、排気口10aが開口されている。
【0020】
サイクロン集塵器9は、連結部9fのところで蓋9dが胴部9eからはずれるようになっている(図1〜2参照)。連結部9は蓋9dが胴部9eが着脱自在に気密的に連結できればよく、本発明ではとくに限定されるものではないが、たとえば蓋および胴部にそれぞれ段差部を設けて嵌合できるもの、または蓋9dおよび胴部9eにそれぞれおねじまたはめねじを形成して螺合できるものであってもよい。また、中筒11を保持するために、円環状のリブ9gが蓋9dの内面に形成されている。したがって、蓋9dを胴部9eから取り外せば、中筒11も容易に胴部9e内部から取り外すことができ、その結果、集塵部9bに捕集されたごみを容易に外部へ捨てることができる。
【0021】
前記実施の形態において、電動送風機7が作動すると、吸込口15に接続したホース(図示せず)を経て床用吸込口(図示せず)から塵埃を含んだ空気がサイクロン集塵器9の吸込口16から図2〜3の蓋9dの半周分の流路9hを通るときに旋回流となって開口9iを介してサイクロン部9aに導入され、ついでサイクロン集塵器9の内周壁に沿って中筒11の傘状の仕切板11aにより塵埃は空気と分離され、集塵部9bに集塵される。
【0022】
一方、前述の旋回流によって浄化された空気は、1次メッシュフィルタ12を通過してさらに浄化され、ついで中筒11内部を通過して2次フィルタ13へいたる。
【0023】
また、塵埃とともに集塵部9bへ入り込んだ空気は、1次メッシュフィルタ18を通過する際に集塵部9b内部の塵埃を圧縮するので、従来のサイクロン式掃除機と比較してごみの圧縮効果を向上させることができる。1次メッシュフィルタ18を通過して浄化された空気は、2次フィルタ13へいたる。
【0024】
そののち、中筒11内外を通過する空気は、2次フィルタ13でろ過されたのち、電動送風機7を通過して集中排気口(図示せず)から外部へ排気される。
【0025】
さらに、本実施の形態では、図1〜2に示されるように、サイクロン集塵器9内部のサイクロン部9aと集塵部9bとを隔てる傘状の仕切板11aが円錐形状を呈するように形成されている。それにより、仕切板11a上に旋回流の影響を受けない吹き溜まりが発生しにくく、比重の軽いごみや髪の毛などの長尺のごみでも仕切板11a上に堆積することなく集塵部9bへスムーズに流れやすくなり、充分な遠心分離効果が長時間得られる。また、遠心分離効果が高いので、浄化された空気が通る1次メッシュフィルタ12および2次フィルタ18の目詰まりがしにくくなり、メンテナンスが楽であり、フィルタの交換または清掃の間隔を長くすることができる。
【0026】
傘状の仕切板11aの傾斜角度θ(図2参照)は、15度以上、好ましくは20度以上になるように設定すれば、遠心分離効果などの効果を確保することができる。
【0027】
また、本発明の他の実施の形態として、図5〜6に示されるように、サイクロン集塵器9のサイクロン部9a内部には、旋回流が導入される開口9iから仕切板11aまでの区間に延びる螺旋状のリブ21が設けられている。この螺旋状のリブ21により、サイクロン部9aにおける風の乱れをなくして風を整流する効果を奏することができ、ごみを集塵部9bへスムーズに流入させることができる。
【0028】
また、集塵部9b内のごみがサイクロン部9aへ向かって巻き上がろうとしても、螺旋状のリブ21に沿って流れる強い風によってごみを集塵部9bに押し戻すことができる。
【0029】
以上のような螺旋状のリブ21の効果により、前記第1次メッシュフィルタ12へのごみの侵入を抑えることができる。したがって、第2次フィルタ13の連続使用期間を延ばすことができ、メンテナンスの回数を少なくすることができる。
【0030】
また、掃除機の使用中に掃除機本体が転倒したとき、電動送風機用の充電池のパワーがダウンしてきたとき、掃除機のON/OFF動作直後など、風量が少ないときでも、螺旋状のリブ21によってサイクロン部9aにおけるサイクロンの遠心分離効果を充分に得ることができ、集塵部9bに集められた細かい塵が舞い上がって第1メッシュフィルタ12が詰まらせたり、第1メッシュフィルタ12を通過した細かい塵が第2次フィルタ13を詰まらせるなどの不具合がなくなる。
【0031】
また、本発明のさらに他の実施の形態として、図7〜8に示されるように、中筒11の外周面にサイクロン集塵器9のサイクロン部9aと集塵部9bとを仕切る螺旋状の仕切板25を設け、仕切板25の一部には、サイクロン部9aで分離した塵埃を集塵部9bに導く通路26を形成し、さらに通路26のサイクロン部9a側の端縁27から集塵部9bに向かってリブ28が延設されている。このリブ28により、螺旋状の仕切板25に沿って流れる空気は、リブ28に沿って集塵部9bに円滑に導かれるため、図9〜10の本発明の比較例であるリブ28のないサイクロン集塵器のように、サイクロン部9a側の端縁27にごみDが絡み付くことがなくなる。
【0032】
【発明の効果】
本発明によれば、集塵部の底面にメッシュフィルタを形成してサイクロン部から集塵部への空気の流れを発生させることにより、集塵部におけるごみの圧縮効果を向上させ、ごみ捨て回数を減少させることができる。
【0033】
また、集塵部からサイクロン部へのごみの巻き上げを抑えることができるため、フィルタなどの目詰まりを低減することができる。たとえば、中筒上部の1次メッシュフィルタまたは丸孔などからの吸込みを抑えることによりメッシュの目詰まり発生回数を抑え、2次フィルタの連続使用期間を延長させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a vacuum cleaner. More specifically, the present invention relates to a vacuum cleaner that improves the separation effect of dust in a cyclone unit and improves the effect of collecting separated dust in a dust collection unit.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 11 to 12, a cyclone provided with an electric blower 51 and a cyclone dust collector 52 connected to the intake side 51 a of the electric blower 51, and the cyclone dust collector 52 is partitioned by a partition plate 60. A cyclonic vacuum cleaner having a portion 53 and a dust collecting portion 54 has been proposed. In such a cyclone type vacuum cleaner, dust and air are separated by a swirling flow in the cyclone unit, the separated dust is collected in the dust collecting unit 54, and the purified air is collected in the cyclone through the inner cylinder 55. The dust is discharged from the duster 52 to the outside.
[0003]
Specifically, the air flow in the middle cylinder 55 is such that the air flows in the order of the opening 55a of the middle cylinder 55, the filter 56, the filter 58, the opening 57a of the second cyclone middle cylinder 57, the middle cylinder 57, and the cylindrical filter 59 in this order. It comes to flow.
[0004]
[Patent Document 1]
Japanese Patent Application No. 2001-38916 (paragraph numbers [0008] to [0009], FIGS. 2 and 4)
[0005]
[Problems to be solved by the invention]
However, in the conventional cyclonic vacuum cleaner, there is substantially no air flow from the cyclone unit 53 to the dust collecting unit 54, so that the dust separated by the cyclone unit 53 is not collected by the dust collecting unit 54. May stick to the filter 56 of the middle cylinder 55. The cyclone unit 53 can sufficiently exert its performance when separating a heavy object such as sand, but it is a garbage with a low specific gravity, especially because it has a poor separation effect on long garbage such as hair. In addition, long and light garbage such as hair winds around the filter 56 of the inner cylinder 55, and further, an umbrella-shaped partition plate 60 that separates the cyclone portion 53 and the dust collection portion 54 from the inner wall of the cyclone dust collector 52. Dust can get clogged in between.
[0006]
The present invention has been made to solve such a problem, and provides a vacuum cleaner that improves the separation effect of dust in the cyclone section and improves the effect of collecting the separated garbage in the dust collection section. For the purpose.
[0007]
[Means for Solving the Problems]
The vacuum cleaner of the present invention includes an electric blower and a cyclone dust collector connected to an intake side of the electric blower, and inside the cyclone dust collector, a cyclone part and a dust collection part for separating dust from air, Is a vacuum cleaner separated by a partition plate, wherein the cyclone dust collector is disposed horizontally such that a rotational axis of a swirling flow generated inside the cyclone portion extends in a substantially horizontal direction, and the cyclone An inlet is formed in a substantially central portion of the partition plate, and a primary filter for further purifying the air purified by the swirling flow of the cyclone unit is disposed in the inlet, and the dust collecting The opening provided in the part communicates with the electric blower to generate an air flow from the cyclone part to the dust collecting part, and passes when the air that has entered the dust collecting part from the cyclone part to the dust collecting part passes through the opening. To air A primary filter for compressing the dust in the dust collecting part, and a secondary filter for filtering the air that has passed through the primary filter of the inlet and the air that has passed through the primary filter of the dust collecting part. It is arranged in the cyclone dust collector, and the air filtered by the secondary filter passes through the electric blower and is exhausted to the outside.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, the vacuum cleaner of the present invention will be described in more detail with reference to the drawings. 1 is a cross-sectional explanatory view showing an embodiment of the vacuum cleaner of the present invention, FIG. 2 is a cross-sectional explanatory view of the cyclone dust collector of FIG. 1, and FIG. 3 is a III-III line of the cyclone dust collector of FIG. 4 is a sectional view taken along line IV-IV of the cyclone dust collector of FIG. 2, FIG. 5 is a sectional explanatory view of the cyclone dust collector in the electric vacuum cleaner according to another embodiment of the present invention, and FIG. FIG. 7 is a cross-sectional view of a cyclone dust collector in a vacuum cleaner according to still another embodiment of the present invention, and FIG. 8 is a cyclone dust collector of FIG. FIG. 9 is a cross-sectional explanatory view of a dust collector without ribs, which is a comparative example of the cyclone dust collector of FIG. 7, and FIG. 10 is an enlarged view of a portion where dust of the dust collector of FIG. It is.
[0011]
The vacuum cleaner shown by FIGS. 1-4 is from the upper case 1 of the cleaner provided with the handle 3 on the upper surface, and the lower case 2 of the cleaner provided with the front wheel 4 for movement and the rear wheel 5 on the lower surface. The battery 6, the wall standing upright from the lower case 2, the electric fan 7 including the fan and the motor installed via the buffer 8, and the packing 14 are detachably provided. The cyclone dust collector 9 is housed. The cyclone dust collector 9 may be formed integrally with the cleaner body.
[0012]
The cyclone dust collector 9 is disposed horizontally so that the rotational axis of the swirling flow generated inside the cyclone portion 9a extends in a substantially horizontal direction. That is, inside the cyclone dust collector 9, the middle cylinder 11 having an umbrella-shaped partition plate 11a is attached in the horizontal direction. The partition plate 11 divides the internal space of the cyclone dust collector 9 into two spaces, a cyclone portion 9a and a dust collection portion 9b that separate dust from air.
[0013]
Thus, by arranging the cyclone dust collector 9 horizontally, the intake port 16 and the exhaust port 10a can be arranged substantially linearly, that is, substantially parallel to the rotational axis of the swirling flow. Thereby, since the exhaust port 10a can be directly connected to the intake side 7a of the electric blower 7, the flow path becomes very simple, and the reduction in the air volume and the work rate can be suppressed. In addition, the outer diameter of the vacuum cleaner can be significantly reduced.
[0014]
Further, the cyclone dust collector 9 is provided with three filters, that is, primary mesh filters 12 and 18 and a secondary filter 13. A plurality of openings 9c are formed radially on the bottom surface of the cyclone dust collector 9, and a primary mesh filter 18 is disposed in the openings 9c. Thus, the cyclone dust collector 9 communicates with the electric blower 8 through the opening 9c having the primary mesh filter 18, and the flow of air from the cyclone portion 9a to the dust collection portion 9b can be generated.
[0015]
The primary mesh filter 12 is disposed in the introduction port 11b at the upper part of the middle cylinder 11, and can filter the air purified in the cyclone portion 9a. The primary mesh filter 12 is not particularly limited in the present invention. For example, a synthetic resin sheet having a large number of openings having a diameter of about 1 mm can be employed. Moreover, a punching metal etc. can also be employ | adopted instead of a synthetic resin sheet. Furthermore, a large number of openings having a diameter of about 1 mm can be formed in the member constituting the upper portion of the middle cylinder 11 and this portion can be used as a primary mesh filter.
[0016]
The primary mesh filter 18 provided in the plurality of openings 9c on the bottom surface of the cyclone dust collector 9 is not particularly limited in the present invention. For example, in order to suppress the intrusion of dust into the secondary filter 13, A mesh having a smaller diameter than the primary mesh filter 12, for example, a filter having a mesh size of about 100 to 250 μm is employed. Moreover, it is preferable that the opening ratio of this mesh is about 50 to 70%.
[0017]
In the present embodiment, an example in which the primary mesh filter 18 is provided in the opening 9c is shown, but the present invention is not limited to this, and other filters may be used instead of the mesh filter.
[0018]
Further, the secondary filter 13 is not particularly limited in the present invention as long as it has a filter function. For example, a filter made of urethane foam, preferably made of Inoac Corporation having a density of about 70 to 90 Kg / m 3 . “Malt filter (trade name)” or the like can be used.
[0019]
Further, a filter lid 10 is attached to the downstream end of the cyclone dust collector 9 in order to press the periphery of the secondary filter 13. An exhaust port 10 a is opened at the center of the lid 10.
[0020]
The cyclone dust collector 9 is configured such that the lid 9d is detached from the body portion 9e at the connecting portion 9f (see FIGS. 1 and 2). The connecting part 9 is not particularly limited in the present invention as long as the lid 9d can be detachably and airtightly connected to the body part 9e. For example, the connecting part 9 can be fitted with a stepped part on the lid and the body part, Or you may form a male screw or a female screw in the lid | cover 9d and the trunk | drum 9e, respectively, and can be screwed together. Further, in order to hold the middle cylinder 11, an annular rib 9g is formed on the inner surface of the lid 9d. Therefore, if the lid 9d is removed from the body portion 9e, the middle cylinder 11 can also be easily removed from the inside of the body portion 9e, and as a result, the dust collected in the dust collection portion 9b can be easily discarded to the outside. .
[0021]
In the above embodiment, when the electric blower 7 is activated, air containing dust is sucked into the cyclone dust collector 9 from the floor suction port (not shown) through a hose (not shown) connected to the suction port 15. When passing through the flow path 9h corresponding to a half circumference of the lid 9d in FIGS. 2 to 3 from the mouth 16, it is introduced into the cyclone portion 9a through the opening 9i, and then along the inner peripheral wall of the cyclone dust collector 9. The dust is separated from the air by the umbrella-shaped partition plate 11a of the middle cylinder 11, and is collected in the dust collecting portion 9b.
[0022]
On the other hand, the air purified by the swirling flow passes through the primary mesh filter 12 and is further purified, and then passes through the inner cylinder 11 to the secondary filter 13.
[0023]
Moreover, since the air that has entered the dust collecting portion 9b together with the dust compresses the dust inside the dust collecting portion 9b when passing through the primary mesh filter 18, the dust compression effect compared with the conventional cyclone cleaner. Can be improved. The air purified through the primary mesh filter 18 reaches the secondary filter 13.
[0024]
After that, the air passing through the inside and outside of the middle cylinder 11 is filtered by the secondary filter 13, then passes through the electric blower 7 and is exhausted to the outside through a concentrated exhaust port (not shown).
[0025]
Furthermore, in this Embodiment, as shown in FIGS. 1-2, the umbrella-shaped partition plate 11a which separates the cyclone part 9a and the dust collection part 9b inside the cyclone dust collector 9 is formed so that a cone shape may be exhibited. Has been. As a result, it is difficult to generate a puddle that is not affected by the swirling flow on the partition plate 11a, and even long dust such as light specific gravity or hair is smoothly deposited on the partition plate 11a without being deposited on the partition plate 11a. It becomes easy to flow and a sufficient centrifugal effect is obtained for a long time. In addition, since the centrifugal separation effect is high, the primary mesh filter 12 and the secondary filter 18 through which the purified air passes are not easily clogged, maintenance is easy, and the interval between filter replacement or cleaning is increased. Can do.
[0026]
If the inclination angle θ (see FIG. 2) of the umbrella-shaped partition plate 11a is set to be 15 degrees or more, preferably 20 degrees or more, effects such as a centrifugal separation effect can be ensured.
[0027]
Moreover, as other embodiment of this invention, as FIG. 5-6 shows, the area from the opening 9i into which the swirl | vortex flow is introduce | transduced into the inside of the cyclone part 9a of the cyclone dust collector 9 to the partition plate 11a A spiral rib 21 is provided. The spiral rib 21 can provide an effect of rectifying the wind by eliminating the turbulence of the wind in the cyclone portion 9a, so that dust can smoothly flow into the dust collecting portion 9b.
[0028]
Moreover, even if the dust in the dust collecting part 9b tries to roll up toward the cyclone part 9a, the dust can be pushed back to the dust collecting part 9b by the strong wind flowing along the spiral rib 21.
[0029]
Due to the effect of the spiral rib 21 as described above, invasion of dust into the primary mesh filter 12 can be suppressed. Therefore, the continuous use period of the secondary filter 13 can be extended, and the number of maintenance can be reduced.
[0030]
Also, when the main body of the vacuum cleaner falls while the vacuum cleaner is in use, the power of the rechargeable battery for the electric blower goes down, or immediately after the vacuum cleaner is turned ON / OFF, even when the air volume is low, the spiral rib 21 can sufficiently obtain the centrifugal separation effect of the cyclone in the cyclone portion 9a, and the fine dust collected in the dust collection portion 9b rises and clogs the first mesh filter 12 or passes through the first mesh filter 12. Problems such as fine dust clogging the secondary filter 13 are eliminated.
[0031]
Further, as still another embodiment of the present invention, as shown in FIGS. 7 to 8, a spiral shape that partitions the cyclone portion 9 a and the dust collection portion 9 b of the cyclone dust collector 9 on the outer peripheral surface of the middle cylinder 11. A partition plate 25 is provided, and a passage 26 is formed in a part of the partition plate 25 to guide the dust separated by the cyclone portion 9a to the dust collection portion 9b. Further, dust is collected from the edge 27 of the passage 26 on the cyclone portion 9a side. A rib 28 is extended toward the portion 9b. Since the air flowing along the spiral partition plate 25 is smoothly guided to the dust collecting portion 9b along the rib 28 by the rib 28, the rib 28 which is a comparative example of the present invention of FIGS. As in the case of the cyclone dust collector, the dust D is not entangled with the edge 27 on the cyclone portion 9a side.
[0032]
【The invention's effect】
According to the present invention, a mesh filter is formed on the bottom surface of the dust collecting part to generate an air flow from the cyclone part to the dust collecting part, thereby improving the dust compression effect in the dust collecting part and reducing the number of times the waste is discarded. Can be reduced.
[0033]
In addition, since dust can be prevented from being rolled up from the dust collection unit to the cyclone unit, clogging of a filter or the like can be reduced. For example, the number of mesh clogging occurrences can be suppressed by suppressing the suction from the primary mesh filter or round hole in the upper part of the middle cylinder, and the continuous use period of the secondary filter can be extended.
