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、サイクロン集塵器のフィルタ部の目詰まりを容易に解消することができる電気掃除機に関する。
【0002】
【従来の技術】
従来より、サイクロン集塵器にフィルタ部を設け、サイクロン部で塵埃などを分離した空気をフィルタ部を介して電動送風機側へ流す電気掃除機が知られている。
【0003】
このようなフィルタ部を有するサイクロン掃除機の構成では、サイクロン部において旋回流により分離できなかった塵埃などが、空気とともにフィルタ部へ流れ、フィルタ部に目詰まりを起こす場合がある。
【0004】
そこで、フィルタ部を掃除するために、フィルタ部の外周面にブラシ体を摺動自在に装着し、使用者が必要に応じてブラシ体を操作し、フィルタ部の掃除を行なうことができる電気掃除機が提案されている(たとえば、特許文献1参照)。
【0005】
【特許文献1】
特開2001−269297号公報
【0006】
【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の構成では、ブラシ体を操作するためにごみなどが付着したフィルタ部近傍を手で触れなければならず、また、フィルタ清掃時にはフィルタ部に付着した塵埃などが飛び散り、不衛生であるとともに、使用者に不快感を与えるなどの問題がある。
【0007】
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、フィルタ部の目詰まりを容易に解消することができる電気掃除機を提供することを目的とする。
【0008】
【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フィルタ部を有するサイクロン集塵器を備えた電気掃除機であって、
前記フィルタ部に逆方向に空気を流す流路切替手段を備えてなることを特徴としている。
【0009】
前記流路切替手段を操作するための操作部を備えるのが好ましい。
【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を吸気口側から見た図、図3は図1のサイクロン集塵器であって通常運転時の空気の流れを示す断面説明図、図4は図3のサイクロン集塵器のIV−IV線断面図、図5は図1のサイクロン集塵器であって除塵動作時の空気の流れを示す断面説明図、図6は本発明の電気掃除機の他の実施の形態を示す断面説明図、図7は図6のサイクロン集塵器を吸気口側から見た図、図8は図6のサイクロン集塵器であって通常運転時の空気の流れを示す断面説明図、および図9は図6のサイクロン集塵器であって除塵動作時の空気の流れを示す断面説明図である。
【0011】
図1〜5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】
サイクロン集塵器9には、本発明のフィルタ部に相当する1次メッシュフィルタ12、および追加の2次フィルタ13が配設されている。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。
【0014】
1次メッシュフィルタ12は、通常運転時では、サイクロン部9aから中筒11内部に導入される空気をろ過することによって、1次メッシュフィルタ12の外周面などに塵埃が付着するため、適当な時期に清掃する必要がある。
【0015】
本実施の形態の電気掃除機は、1次メッシュフィルタ12に対して通常運転時の場合と逆方向(すなわち、中筒11の外へ出る方向)に空気を流すように空気の流路を切り替える流路切替機構21を備えている。そのため、流路切替機構21により流路を切り替えるだけで、1次メッシュフィルタ12に逆方向に空気を流し、1次メッシュフィルタ12に付着した塵埃などを吹き飛ばすことができ、フィルタ部の目詰まりを容易に解消することができる。
【0016】
流路切替機構21は、図2〜4に示されるように、3つの弁部分、すなわち、蓋9dの半周分の流路9hを開閉する弁板22、中筒11上部の流路を切り替える弁板23、および中筒11の集塵部9bに露出する部分に形成された開口11cを開閉する弁筒24を備えている。これらの弁板22、弁板23および弁筒24を含む可動部分は、共通のシャフト25を介して互いに一体的に結合され、中筒11の軸方向に沿って往復移動できるように配設されている。なお、本実施の形態のシャフト25は、弁板23と一体形成された部分25aと、弁筒24と一体形成された部分25bとからなり、これら2つの部分がネジ26によって互いに連結されているが、1本のシャフトで作製してもよい。
【0017】
弁板22は、シャフト25に結合された中空の連結部材27内部に配設されている。図3〜4に示されるように、弁板22は、通常運転時では流路9hを開放しているが、1次メッシュフィルタ12の除塵動作時(以下、単に除塵動作時という)では流路9hのほぼ出口付近に入ってきて、流路9hから開口9iを介してサイクロン部9aへ至る空気の流れを遮断する。
【0018】
弁板23は、通常運転時では中筒11の一端に連通する蓋9dの開口9jを閉じ、除塵動作時では開口9jを開けるとともに中筒11の中央の導入口11bと開口11cとの境界部分を閉じるように、中筒11内部に配設されている。
【0019】
弁筒24は、通常運転時では中筒11の開口11cを閉じ、除塵動作時では開口11cを開けるように、中筒11内部に配設されている。弁筒24は、シャフト25の部分25bに対して、空気の通過を許す複数本のリブ24aまたは孔開きプレートなどを介して連結されている。
【0020】
また、開口11cには、前記導入口bに設けられた1次メッシュフィルタ12のようなメッシュフィルタやパンチングメタルなどのフィルタ28(図5参照)が配設されている。
【0021】
図2〜5に示される流路切替機構21では、連結部材27が手動操作ボタンの役目をするので、連結部材27を外部から指などで押し込むことにより、通常運転から除塵動作へ移行することができる。さらに、シャフト25の部分25aの周囲で、連結部材27と蓋9dの上面とのあいだには、圧縮コイルバネ29などの付勢手段が設けられているため、指などからの操作力を除けば、バネ29の付勢力により、再び除塵動作から通常運転の状態へ復帰することができる。
【0022】
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。
【0023】
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。
【0024】
サイクロン集塵器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連結部を有するのが好ましい。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。
【0025】
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。
【0026】
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へ至る。
【0027】
そののち、中筒11内を通過する空気は、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。
【0028】
第1メッシュフィルタ12の外周に付着した塵埃を取り除くために、除塵動作を行なう場合、電動送風機7を作動した状態で、図5に示されるように、連結部材27を指で押し込むことにより、弁板22が流路9hを塞ぎ、吸気口16からの空気の流入を止める。
【0029】
それとともに弁板23が、開口9jを開けるととともに中筒11の中央の導入口11bと開口11cとの境界部分を閉じることにより、電動送風機7の負圧により、開口9jから外気が導入され、中筒11の外方へ向かって空気が流れ、第1メッシュフィルタ12の外周に付着した塵埃をサイクロン部9aに吹き飛ばすことができる。
【0030】
さらに、このとき、弁筒24は、開口11cを開けているため、サイクロン部9aから塵埃とともに集塵部9bに流入した空気は、フィルタ28でろ過されたのち、再び、中筒11内部に流入し、2次フィルタ13を通過したのち外部へ排気される。
【0031】
除塵動作完了後、連結部材27から指を離せば、圧縮コイルバネ29の復元力により、図3に示される通常運転の状態へ復帰することができる。
【0032】
また、本発明の電気掃除機の他の実施の形態として、図6〜9に示されるように、連結部材27を指で押す代わりにシャフト25を駆動機構31によって往復移動させて流路切替機構21を操作することにより、通常運転状態(図8参照)および除塵動作時の状態(図9参照)のいずれかに自動的に移行させることができる。なお、図6〜9に示される符号のうち、図1〜5に示される符号と共通のものについては、図1〜5で示される構成部分と共通している。
【0033】
駆動機構31は、電動モータと、ラックおよびピニオンなどの回転力を直線駆動力に変換する変換機構とからなり、出力端である往復駆動ロッド32(図9参照)がシャフト25に固着されている。
【0034】
駆動機構31は、掃除機のパイプなどに設けられた手元スイッチなどによって遠隔操作することができる。
【0035】
また、掃除機本体の運転開始時に強制的に所定の時間だけ除塵動作を行なうように、制御用マイコンなどを用いて駆動機構31を自動制御してもよい。
【0036】
【発明の効果】
本発明によれば、流路切替手段により流路を切り替えるだけで、フィルタ部に逆方向に空気を流し、フィルタ部に付着した塵埃などを吹き飛ばすことができ、フィルタ部の目詰まりを容易に解消することができる。
【0037】
また、フィルタ部の目詰まりが解消するため、電動送風機の負担が減少し、電動送風機の寿命も長くなる。

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 section 9b.
[0026]
On the other hand, the air purified by the above-described swirling flow passes through the primary mesh filter 12 and is further purified, and then passes through the inside of the middle cylinder 11 to reach the secondary filter 13.
[0027]
After that, the air passing through the middle cylinder 11 is filtered by the secondary filter 13 and then passes through the electric blower 7 and is exhausted to the outside through a centralized exhaust port (not shown).
[0028]
When a dust removing operation is performed in order to remove dust attached to the outer periphery of the first mesh filter 12, with the electric blower 7 being operated, as shown in FIG. The plate 22 blocks the flow path 9h, and stops the inflow of air from the intake port 16.
[0029]
At the same time, the valve plate 23 opens the opening 9j and closes the boundary between the inlet 11b at the center of the middle cylinder 11 and the opening 11c, so that outside air is introduced from the opening 9j by the negative pressure of the electric blower 7, The air flows toward the outside of the middle cylinder 11, and the dust attached to the outer periphery of the first mesh filter 12 can be blown off to the cyclone portion 9a.
[0030]
Further, at this time, since the valve cylinder 24 has opened the opening 11c, the air that has flowed into the dust collecting part 9b together with the dust from the cyclone part 9a is filtered by the filter 28 and then flows into the inside of the middle cylinder 11 again. Then, after passing through the secondary filter 13, it is exhausted to the outside.
[0031]
If the finger is released from the connecting member 27 after the dust removing operation is completed, the state of the normal operation shown in FIG. 3 can be returned by the restoring force of the compression coil spring 29.
[0032]
In addition, as another embodiment of the vacuum cleaner of the present invention, as shown in FIGS. 6 to 9, instead of pushing the connecting member 27 with a finger, the shaft 25 is reciprocated by the drive mechanism 31 to switch the flow path. By operating 21, it is possible to automatically shift to either the normal operation state (see FIG. 8) or the state during the dust removal operation (see FIG. 9). In addition, among the reference numerals shown in FIGS. 6 to 9, the same reference numerals as those shown in FIGS. 1 to 5 are common to the components shown in FIGS. 1 to 5.
[0033]
The drive mechanism 31 includes an electric motor and a conversion mechanism that converts a rotational force of a rack, a pinion, or the like into a linear drive force. A reciprocal drive rod 32 (see FIG. 9) that is an output end is fixed to the shaft 25. .
[0034]
The drive mechanism 31 can be remotely operated by a hand switch or the like provided on a pipe or the like of the vacuum cleaner.
[0035]
Further, the driving mechanism 31 may be automatically controlled by using a control microcomputer or the like so as to forcibly perform the dust removing operation for a predetermined time when the operation of the cleaner body is started.
[0036]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, only by switching a flow path by a flow path switching means, air can be made to flow in a reverse direction to a filter part, and the dust etc. which adhered to the filter part can be blown off, and the clogging of a filter part is easily eliminated. can do.
[0037]
Further, since the clogging of the filter portion is eliminated, the load on the electric blower is reduced, and the life of the electric blower is prolonged.
