【０００１】
【発明の属する技術分野】
本発明は、清掃機の塵を吸入する装置に係るもので、詳しくは、二つのブラッシュを使用して清掃機の性能を向上し得る清掃機の吸入装置に関するものである。
【０００２】
【従来の技術】
一般に、ロボット清掃機は、使用者の操作なしに、自身が移動しながら清掃を行い、充電器の電力が消耗されると、自身が充電体に移動して充電を行って充電が終了されると、再び清掃区域に戻ることで、清掃を継続し得るようになっている。
【０００３】
そして、従来のロボット清掃機においては、図６に示したように、清掃機本体１０２と、該清掃機本体１０２に収納されて吸入力を発生する吸入モータ１０４と、該吸入モータ１０４の後方に装着されて、該吸入モータ１０４により吸入される塵又は汚物を集塵するフィルター１０６が収納されたフィルターコンテナ１０８と、該フィルターコンテナ１０８に吸入管１１０により連結されて前記本体の下面に切削形成されることで、床１５０上の塵又は汚物を吸入する吸入口１１２と、該吸入口１１２の内部のヒンジ軸１３６に回動自在に軸支されて床上の汚物を吸入するブラッシュ１１４と、前記清掃機を自動的に走行させて清掃を行う制御部１１６と、から構成されている。
【０００４】
且つ、前記清掃機本体１０２の内部前方には、障害物の位置を把握するために前記清掃機本体１０２の移動時に超音波を送信する超音波送信部１１８と、該超音波送信部１１８から送信された超音波を受信する超音波受信部１２０と、が装着されている。
又、前記清掃機本体１０２の内部後方側には、充電端子１２２及び充電バッテリ１２８が装着され、室内の壁面１２４には接続端子１２６が設置されることで、該接続端子１２６に前記充電端子１２２が接続されて、前記充電バッテリ１２８が充電されるようになっている。
【０００５】
又、前記清掃機本体１０２の後方側壁には、前記充電端子１２２を前記室内壁面１２４の接続端子１２６に誘導するとき必要な発光部１４０が装着され、前記室内壁面１２４の接続端子１２６の下方には受光部１４２が装着されることで、前記清掃機本体１０２の発光部１４０から発光される光信号を受光するようになっている。

【０００６】
このように構成された従来の清掃機の動作を説明すると、次のようである。
使用者が動作ボタンを押すことで、充電バッテリ１２８の電源が吸入モータ１０４に伝達されて該吸入モータ１０４が駆動されると、床上の塵及び汚物が吸入口１１２から吸入されて吸入管１１０を通ってフィルター１０６に捕集される。この時、前記ブラッシュ１１４が回転されながら床上の塵及び汚物を吸入口１１２の内部に吸入し、制御部１１６から印加される信号によって駆動モータ１０４が駆動され、清掃機本体１０２が移動しながら自動的に清掃作業が実施される。
【０００７】
次いで、前記清掃機本体１０２が移動されると、該清掃機本体１０２の前方の超音波送信部１１８及び超音波受信部１２０の動作により障害物を避けながら移動する。また清掃作業中、充電バッテリ１２８の電圧レベルが設定値以下まで低下すると、制御部１１６の制御により清掃作業が中止され、清掃機本体１０２は室内壁面の接続端子１２６まで移動して、前記清掃機本体１０２の後面の充電端子１２２が前記接続端子１２６に連結されることで、充電バッテリ１２８の充電が実施される。
次いで、充電バッテリ１２８の充電が終了されると、前記制御部１１６の制御により清掃機本体１０２の充電端子１２２が接続端子１２６から分離されて、再び清掃作業が実施される。
【０００８】
【発明が解決しようとする課題】
然るに、このような従来の清掃機においては、一つのブラッシュを用いて床上にくっついた汚物をひきとったり、又は大きい汚物を吸入するようになっているため、それら清掃作業が難しく、このような汚物が多い場合は全てを除去して清掃を奇麗に行うことが困難であるという不都合な点があった。
且つ、このような短所を補完するため、吸入モータの容量を大きくして吸入力を増大させると、原価が上昇し、騷音が増加するという不都合な点があった。

又、それら駆動機構３６、３８は、図２に示したように、前記第１ヒンジ軸４０を回動させる第１駆動機構３６と、前記第２ヒンジ軸４２を駆動させる第２駆動機構３８と、から構成されることで、それら第１ブラッシュ３２及び第２ブラッシュ３４を夫々個別的に駆動させる。
【００１７】
即ち、前記第１及び第２駆動機構３６、３８は、前記制御部６から印加される信号によって正方向及び逆方向に駆動される第１及び第２駆動モータ４６、４８と、それら第１及び第２駆動モータ４６、４８と前記第１及び第２ヒンジ軸４０、４２間に連結されることで、前記第１及び第２駆動モータ４６、４８の駆動力を前記第１及び第２ヒンジ軸４０、４２に夫々伝達する動力伝達機構から構成される。

【００１８】
このように構成された本発明に係る清掃機の吸入装置の動作を説明すると次のようである。
使用者が清掃機の動作スイッチをオンさせると、充電バッテリ１６の電源が吸入モータ２２に印加されて、該吸入モータ２２が駆動され、該吸入モータ２２の吸入力により床上の塵及び汚物が吸入口３０に吸入されることで、吸入管２８を通してフィルター２４に捕集される。

【００２０】
例えば、カーペットの上面を走行して清掃をするときは、図４に示したように、第１ブラッシュ３２及び第２ブラッシュ３４の回転方向を、矢印Ｒ方向と同様に夫々回転させることで、カーペットの縺れを防止することができる。
且つ、収去される汚物の容積が大きいため、前記第１ブラッシュ３２と第２ブラッシュ３４間に汚物が挟まるときは、図５に示したように、第１ブラッシュ３２を矢印Ｓ方向に回転させ、第２ブラッシュ３４は矢印Ｔ方向に回転させることで、それら第１ブラッシュ３２と第２ブラッシュ３４間に挟まった汚物を取り出すようになっている。
【００２１】
このように、第１ブラッシュ３２及び第２ブラッシュ３４の回転方向を清掃中の条件によって制御部６により変換させることで、廉価で奇麗な掃除を行うことができる。
又、前記動力伝達機構の他の実施形態として、前記第１及び第２駆動モータの回転軸に嵌合される各駆動プーリ５０、５２と、前記第１、第２ヒンジ軸４０、４２に嵌合される各従動プーリ５４、５６と、を夫々ギヤーに代替して構成することもできる。
又、このように構成された本発明に係る清掃機の吸入装置は、ロボット清掃機は勿論で、一般の如何なる清掃機にも利用することができる。
【００２２】
