【従来の技術】
従来の電気掃除機の構成を図8を用いて説明する。有底の集塵室31を設け、内部に吸気する吸気口32を集塵室31の側壁に接線方向に向け設けている。集塵室31の上端開口部33を覆うように蓋体34を設け、この蓋体34に排気口35を設ける。また集塵室31の上端開口部33を覆うようにフィルター36を取り付けている。電動送風機37が運転すると、塵埃は吸込部38より吸引され、吸気口32より集塵室31内に吸気され、集塵室31内で遠心分離され、排気はフィルター36を通して排気口35より排出される(特許文献1参照)。

【0011】
【実施例】
以下、本発明の一実施例について、図1〜図7を参照しながら説明する。
【0012】
図1は電気掃除機の正面図である。本掃除機は、下部に床面の塵埃を吸引する吸込具1、吸引風を発する電動送風機3を内蔵した掃除機本体18、一端を前記吸込具1に接続した延長管2、前記掃除機本体18より着脱でき塵埃を捕集する集塵部4、この集塵部4と前記吸込具1を連通する吸引通路を前記延長管2を介して形成し、前記延長管2と前記集塵部4とを接続するホース5から構成されている。また、前記掃除機本体18には、前記電動送風機3が発する排気を排出する排出穴(図示せず)が設けられている。
【0013】
図2は、電気掃除機の集塵部4を構成する、第1塵埃分離部6、第1塵埃分離部である遠心分離部7及び集塵蓋8の構成図である。第1塵埃分離部6は、下方に開口部を有し、開閉自在の開閉蓋17にて覆われている。また、第1塵埃分離部6には、吸込具1よりホース5を介して塵埃を含んだ気流が流入する第1流入口9が設けられている。遠心分離部7は、前記第1塵埃分離部6より小径に形成されており、内部に略円形空間を有していて、前記第1塵埃分離部6内に配設されている。集塵蓋8は、エラストマーのような軟質材を外周に有し略円筒形状で、前記遠心分離部7の吸気下流側に配設されている。12は前記電動送風機室3の吸引口(図示せず)と前記遠心分離部7の内部を連通する第1連通口でフィルターにて覆われている。10は遠心分離部7内方へ塵埃を含んだ気流を流入する略円弧状の第2流入口で、フィルターにて覆われており、前記第1流入口9と対向しない位置に設けられている。なお、前記略円弧状の第2流入口は着脱自在で、前記フィルターの掃除もできる。
【0014】
14は遠心分離部7に設けた略円筒形状の壁面部、11は遠心分離部に設けた略円筒形状の壁面部14の内方に設けられ、前記第2流入口10より流入した塵埃を含む気流を、前記遠心分離部7の壁面部14の内壁に沿って、旋回させるための旋回通路11aを形成するために配設した略円弧状の旋回部11である。前記略円弧の旋回部11の内方のみが、前記第1連通口12と連通する構成となっている。15は前記旋回通路11aの吸気下流側かつ前記旋回部の外方で、遠心分離部7底面に設けた第1開口部である。16は旋回部11より延設して遠心分離部7の壁面部14の内壁に接するように形成したガイド部で、前記旋回通路11aの吸気下流側のみが前記第1開口部15と連通する構成としている。
【0015】
図3は、図2のA矢視図である。20は前記第1開口部15と連通しかつ下方に一体的に形成された細塵蓄積部である。また、13は第1塵埃分離部6内に配され、前記第1塵埃分離部6内にて吸引風から分離された高密度塵埃の塵埃を蓄積する高密度塵埃蓄積部で、24は同じく第1塵埃分離部6内に配され、前記第1塵埃分離部6内にて吸引風から分離された低密度塵埃の塵埃を蓄積する低密度塵埃蓄積部であり、図4の集塵部4の断面図に示すように第1塵埃分離部6内に配設された区画壁22と前記第1塵埃分離部6の開口部を覆う開閉蓋17に配設された区画壁25によって区画されている。なお、前記高密度塵埃蓄積部13は前記低密度塵埃蓄積部24より、前記第1流入口9に対して遠方に配置してある。前記低密度塵埃蓄積部24は、第2開口部21を有し、前記第2開口部21はフィルター23にて覆われている。19は電動送風機3の吸引口(図示せず)と、前記第2開口部21を介して、前記低密度塵埃蓄積部24とを連通される第2連通口である。つまり、前記第2開口部21は、電動送風機3の吸引口(図示せず)と前記低密度塵埃蓄積部24とを連通させる連通部の役割を果たしている。
【0016】
図5〜図7は、集塵部4の区画壁部の構成例の断面図である。図5に示す25bは第1塵埃分離部6内に配設された区画壁22よりも開閉蓋17の回動軸26に近い側に配設された区画壁の場合である。また、図6に示す25cは開閉蓋17の区画壁の先端断面を略L字状に形成した場合である。また、図7に示す27は区画壁25aの上部に設けた弾性体で、第1塵埃分離部6内に配設された区画壁22と区画壁25aの間に挟まれる構成とした場合である。いずれの構成においても、第1塵埃分離部6内に配設された区画壁22は、前記第1塵埃分離部6の下端部より突出していないため、開閉蓋17を開いた状態で、前記第1塵埃分離部6の下方の開口側を下側にして、被掃除面上等にそのまま置いても、前記第1塵埃分離部内に形成した区画壁22が、前記被掃除面上等に直接当たることがないため、破損等が生じることもなく、耐久性および使用性が向上できる。
【0017】
上記構成による動作作用を説明する。前記吸込具1より吸引した塵埃は、ホース5内を通った後、前記第1流入口9より前記第1塵埃分離部6に吸引される。第1流入口9より、第1塵埃分離部6に吸引された塵埃を含む吸引風は、遠心分離部7に設けた略円筒形状の壁面部14に沿って旋回する。前記第1塵埃分離部6内においては、図3に示すように、低密度塵埃蓄積部24に吸引力が作用しているので、体積の大きい塵埃が吸引力を受けやすいのと、重量の大きい塵埃が遠心力が大きいため、高密度塵埃は遠心力が大きく、低密度塵埃は遠心力が小さいこととなる。これにより、高密度塵埃は、第1流入口9に対して低密度塵埃蓄積部24より遠方に配置してある高密度塵埃蓄積部13に、区画壁22の先端開放部を通過後蓄積され、低密度塵埃は前記第1流入口9近傍の低密度塵埃蓄積部24に蓄積されることとなる。
【0018】
また、低密度塵埃蓄積部24の内部と電動送風機3の吸引口(図示せず)とを連通する第2開口部21を設けているため、低密度塵埃蓄積部24に蓄積された低密度塵埃は、吸引力により前記第2開口部側から蓄積されていく。特に低密度塵埃は、重量が小さく体積の大きい綿やティシュ等の通気性が良い塵埃が多いことに加え、第2開口部21を覆うフィルター23を、前記第2開口部21の下端(低密度塵埃蓄積部24の下端)から所定高さの位置に設けているため、フィルター23の目詰まりを防止できることで集塵性能を向上できる。
【0019】
さらに、フィルター23の目詰まりを起こし易い体積の小さい高密度塵埃は、第1塵埃分離部6内に配設された区画壁22と開閉蓋17に配設された区画壁25aにて囲まれ、吸引力の作用しない前記高密度塵埃蓄積部13内に蓄積されており、フィルター23には付着しないため、フィルター23の目詰まりを防止できることで集塵性能を向上できる。
【0020】
さらに、前記低密度塵埃蓄積部24内の吸引作用により、低密度塵埃蓄積部24内で蓄積されている低密度塵埃の舞い上がりを防止できるため、遠心分離部7の第2流入口10のフィルターへの塵埃の付着を防止でき、集塵性能を向上できる。第1流入口9より、第1塵埃分離部6に吸引された塵埃を含む吸引風は、遠心分離部7の略円筒形状の壁面部14に設けた略円弧状の第2流入口のフィルターに沿って旋回するため、前記フィルターをクリーニングすることで、集塵性能を向上できる。
【0021】
質量および体積の大きい塵埃は、第1塵埃分離部6内に捕集されるが、質量および体積の小さい細塵は、前記第2流入口10を経て遠心分離部7内方へ吸引される。この遠心分離部7内方へ吸引された塵埃を含む気流は、前記遠心分離部7の壁面部14の内壁と略円弧状の旋回部11とにより形成された旋回通路11a内を旋回することで気流と塵埃は分離し、前記塵埃と分離した気流は、その後、前記旋回通路11aの吸気下流側の開放部より旋回部11の内方に流入し、また、略円弧状の旋回部11の内方のみが、電動送風機3の吸引口(図示せず)と連通する第1連通口12と連通する構成となっているため、前記気流は前記第1連通口12を介して掃除機本体18外へと排出される。
【0022】
一方、前記気流と分離した塵埃は、第1開口部15を介して細塵蓄積部20に蓄積される。前記細塵蓄積部20は、開閉蓋17にて覆われていて閉塞された状態であるため、前記細塵蓄積部20内に気流は生じず確実に内部に蓄積される。そのため、遠心分離部7にて遠心分離され細塵蓄積部20に蓄積している塵埃を、再度遠心分離部7へ逆流するのを防止できる。また、第1塵埃分離部6内に、それぞれ下方開口の高密度塵埃蓄積部13と低密度塵埃蓄積部24と細塵蓄積部20とが、水平方向に並んで配設されていているため、開閉蓋17を開くと、高密度塵埃蓄積部13と低密度塵埃蓄積部24と細塵蓄積部20のそれぞれに蓄積されている塵埃が同時に落下するため、前記第1塵埃分離部6に捕集されていた塵埃とともに、一度に廃棄できる。
【0023】
【発明の効果】
本発明によれば、吸引力が急激に低下するのを防止することで集塵性能を向上させ、かつ小型化を実現した電気掃除機を提供できる。

The suction air containing dust sucked into the first dust separation unit 6 from the first inlet 9 turns along the substantially cylindrical wall surface 14 provided in the centrifugal separation unit 7. In the first dust separating section 6, as shown in FIG. 3, a suction force acts on the low-density dust accumulation section 24, so that large-volume dust is easily subjected to the suction force and heavy. Since the dust has a large centrifugal force, the high-density dust has a large centrifugal force, and the low-density dust has a small centrifugal force. Thereby, the high-density dust is accumulated in the high-density dust accumulation unit 13 located farther than the low-density dust accumulation unit 24 with respect to the first inlet 9 after passing through the open end of the partition wall 22, The low-density dust is stored in the low-density dust storage unit 24 near the first inlet 9.
[0018]
Further, since the second opening 21 communicating the inside of the low-density dust accumulation unit 24 and the suction port (not shown) of the electric blower 3 is provided, the low-density dust accumulated in the low-density dust accumulation unit 24 is provided. Are accumulated from the second opening side by the suction force. In particular, low-density dust has a large amount of dust having good air permeability such as cotton and tissue having a small weight and a large volume, and a filter 23 covering the second opening 21 is provided at the lower end of the second opening 21 (low-density). Since the filter 23 is provided at a position at a predetermined height from the lower end of the dust accumulation unit 24), clogging of the filter 23 can be prevented, thereby improving dust collection performance.
[0019]
Further, the high-density dust having a small volume that easily causes clogging of the filter 23 is surrounded by the partition wall 22 provided in the first dust separating unit 6 and the partition wall 25a provided in the opening / closing lid 17, Since the dust is accumulated in the high-density dust accumulation section 13 where no suction force acts and does not adhere to the filter 23, clogging of the filter 23 can be prevented, so that dust collection performance can be improved.
[0020]
Further, the suction action in the low-density dust accumulation unit 24 can prevent the low-density dust accumulated in the low-density dust accumulation unit 24 from rising. Dust can be prevented from adhering and dust collection performance can be improved. The suction air containing dust sucked into the first dust separation unit 6 from the first inlet 9 passes through the substantially arc-shaped second inlet filter provided on the substantially cylindrical wall 14 of the centrifugal separator 7. Since it turns along, the dust collection performance can be improved by cleaning the filter.
[0021]
Dust having a large mass and volume is collected in the first dust separation unit 6, while fine dust having a small mass and volume is sucked into the centrifugal separation unit 7 through the second inlet 10. The airflow including dust sucked into the centrifugal separation unit 7 is swirled in a swirl passage 11 a formed by the inner wall of the wall surface 14 of the centrifugal separation unit 7 and the substantially circular swirl unit 11. The airflow and the dust are separated, and the airflow separated from the dust then flows into the swirling portion 11 from an open portion of the swirl passage 11a on the downstream side of the intake air. Only one of the air blowers communicates with the first communication port 12 which communicates with the suction port (not shown) of the electric blower 3, so that the air flow is outside the cleaner main body 18 via the first communication port 12. Is discharged to
[0022]
On the other hand, the dust separated from the airflow is accumulated in the fine dust accumulation unit 20 through the first opening 15. Since the fine dust accumulation unit 20 is covered with the opening / closing lid 17 and is closed, no airflow occurs in the fine dust accumulation unit 20 and the fine dust accumulation unit 20 is reliably accumulated inside. Therefore, it is possible to prevent the dust that has been centrifuged in the centrifugal separation unit 7 and accumulated in the fine dust accumulation unit 20 from flowing back to the centrifugal separation unit 7 again. In addition, since the high-density dust accumulation unit 13, the low-density dust accumulation unit 24, and the fine dust accumulation unit 20 each having a lower opening are arranged horizontally in the first dust separation unit 6, When the opening / closing lid 17 is opened, the dust accumulated in each of the high-density dust accumulation unit 13, the low-density dust accumulation unit 24, and the fine dust accumulation unit 20 simultaneously drops, and is collected by the first dust separation unit 6. It can be discarded at once with the dust that has been used.
