Description

【０００１】
【発明の属する技術分野】
本発明は、ドラムの回転時にドラム内壁に取り付けられた複数枚のベーンが洗濯物を押し上げてから落下させることによって洗濯を行うドラム式洗濯機に関し、特に、ベーンの形状を変更することによって洗濯物と洗濯水との接触面積を広げるとともに、ドラムの回転時に洗濯物を水平方向に流動させることによって洗濯およびすすぎの性能を向上させたドラム式洗濯機に関する。
【０００２】
【従来の技術】
一般に、ドラム式洗濯機は、水平に設けられる水槽およびドラム内側に洗剤、洗濯水および洗濯物が投入された状態でモータの駆動力によって回転されるドラムと洗濯物間の摩擦を利用して洗濯するものであって、洗濯物の絡み付きや損傷が殆どなく、叩いたり擦ったりして洗う洗濯効果がある。
図９は、従来技術によるドラム式洗濯機の側断面図であり、図１０は従来技術によるドラム式洗濯機についているベーンの斜視図であり、図１１は、図１０のａ−ａ線における断面図である。
【０００３】
従来の技術によるドラム式洗濯機は、図９に示すように、前面に投入口（図示せず）が形成されたキャビネット２と、前記投入口に開閉可能に取り付けられるドア２ａと、前記キャビネット２の内側に水平に配設され、洗濯水を収容する水槽４と、前記水槽４内側に回転可能に配設されて洗濯物を収容するドラム６と、前記水槽４の後方に配設されて回転力を発生させるモータ８と、前記モータ８とドラム６との間に配設されて動力を伝達するよう、前記ドラム６の背面に固定されるスパイダー１０および前記スパイダー１０とモータ８との間に連結される回転軸１２と、前記ドラム６の内壁に一定間隔をおいて突設さられ、前記ドラム６の回転時に洗濯物を上に押し上げ頂点近くで落下させる複数枚のベーン２０とを含めて構成される。
【０００４】
ここで、前記水槽４とドラム６は、前記投入口から洗濯物が投入され得るように前方が開口された円筒形で形成されるものの、前記ドラム６は内壁に多数の脱水孔６ａが形成され、前記ベーン２０は前記ドラム６の内壁に突設される。
特に、前記ベーン２０は、図１０および図１１に示したように、上端が互いに連結されるように上方に傾くように形成された左、右側傾斜面２２、２４と、前記左、右側傾斜面２２、２４の前、後端を塞ぐ前、背面２６、２８とから構成されるが、その内部を洗濯水が循環できるように下面が開放され、上端には洗濯水が循環されるように孔２０ａが形成される。
【０００５】
このとき、前記左、右側傾斜面２２、２４は平板状からなり、前記左、右側傾斜面２２、２４が互いに連結される上端部分は前記ドラムの回転中心Ｃと水平に形成され、前記ドラム６の内壁に固定されるベーン２０の下端は前記ドラムの回転中心Ｃと水平な四角形に形成される。
したがって、前記ドラム６が回転する時、前記ドラム６の低部に置かれていた洗濯物は前記ベーン２０によって前記ドラム６の円周方向に沿って一定高さまで押し上げられてから前記ドラム６の下部に落下するが、この落差による衝撃力と屈伸によって洗濯およびすすぎが行われる。
【０００６】
しかし、従来技術によるドラム式洗濯機は、前記ベーンの左、右側傾斜面２２、２４が平板状になっており、洗濯物が前記ベーン２０にかけられても前記左、右側傾斜面２２、２４に沿って滑り落ち易いので、洗濯物を一定高さまで押し上げ難く、洗濯およびすすぎ性能を向上させるには限界があった。
【０００７】
また、従来技術によるドラム式洗濯機は、前記ベーン２０が前記ドラムの回転中心Ｃと水平に形成されているので、前記ドラム６の回転時に洗濯物が前記ドラム６の限定された内周面に沿って垂直方向にのみ流動できず、そのため、洗濯物が前記ドラム６内に不揃いに分布されると、脱水時前記ドラム６内で洗濯物が偏った状態で前記ドラム６が高速回転し、大きな振動と騒音を生じさせるという問題があった。
【０００８】
【発明が解決しようとする課題】
本発明は、前記従来技術の問題点を解決するために案出されたものであり、洗濯物が容易にかけられることは勿論、洗濯物を一定高さまで押し上げてから落下させることによって、洗濯物の流動性を増大させ、洗濯およびすすぎの性能を向上させたドラム式洗濯機を提供することにその目的がある。
【０００９】
【課題を解決するための手段】
前記目的を達成するために、本発明によるドラム式洗濯機は、キャビネットの内側に水平に配設されて洗濯水を収容する水槽と、前記水槽内側に回転可能に配設されて洗濯物を収容するドラムと、前記ドラム内壁に突設され、前記ドラムが回転するとき洗濯物を押し上げてから落下させて垂直方向に流動させると同時に、洗濯物および洗濯水との接触面積を広げるために左、右側傾斜面のうち少なくともいずれか一つの傾斜面が凹状に形成される複数枚のベーンと、から構成される。
【００１０】
また、本発明によるドラム式洗濯機は、キャビネットの内側に水平に配設されて洗濯水を収容する水槽と、前記水槽の内側に回転可能に配設されて洗濯物を収容するドラムと、前記ドラム内壁に突設され、前記ドラムが回転するとき洗濯物を案内して水平方向に流動させ得るように前記左、右側傾斜面の連結部分の上端が前記ドラムの回転中心に対して傾いた直線形状に形成される複数枚のベーンと、から構成される。
【００１１】
【発明の実施の形態】
以下、本発明の実施形態を添付図面を参照しつつ詳細に説明する。
図１は、本発明によるドラム式洗濯機の一例を示す側断面図であり、図２は本発明によるドラム式洗濯機におけるベーンの一例を示す斜視図であり、図３ないし図５はそれぞれ、図２のＡ−Ａ、Ｂ−Ｂ、Ｃ−Ｃ線における断面図である。
【００１２】
図１に示すように、本発明によるドラム式洗濯機の第１実施形態は、前面に投入口（図示せず）が形成されたキャビネット５２と、前記投入口に開閉可能に取り付けられたドア５２ａと、前記キャビネット５２の内側に水平に配設されて洗濯水を収容する水槽５４と、前記水槽５４内側に回転可能に配設されて洗濯物を収容し、回転時洗濯物と摩擦されて洗濯が行われるドラム５６と、前記水槽５４の後方に配設されて回転力を発生させるモータ５８と、前記モータ５８とドラム５６との間に配設されて動力を伝達するよう、前記ドラム５６の背面に固定されるスパイダー６０および前記スパイダー６０とモータ５８との間に連結される回転軸６２と、前記ドラム５６の内壁に円周方向に一定間隔をおいて突設されて前記ドラム５６の回転時に洗濯物を押し上げてから落下させるとともに、洗濯物を案内して水平方向に流動させるベーン７０と、を含めて構成される。
【００１３】
勿論、本発明によるドラム式洗濯機は、洗濯時前記水槽５４およびドラム５６内に洗濯水を供給する給水手段６４と、すすぎおよび脱水時前記水槽５４およびドラム５６内の洗濯水を排水させる排水手段６６とをさらに含む。
ここで、前記水槽５４とドラム５６は、前記投入口から洗濯物が投入され得るように前方が開口された円筒形で形成されるものの、前記ドラム５６は内壁に多数の脱水孔５６ａが形成され、前記ベーン７０は前記ドラム５６の内壁に突設される。
【００１４】
特に、前記ベーン７０は、図２に示したように、上端が互いに連結されるように上方に傾くように形成された左、右側傾斜面７２、７４と、前記左、右側傾斜面７２、７４の前、後端を塞ぐ前、背面７６、７８とから構成され、その内部を洗濯水が循環できるように下面が開放され、上端には洗濯水が循環されるように一定間隔をおいて孔７０ａが形成される。
【００１５】
このとき、前記左、右側傾斜面７２、７４は、前記ドラムの前方からみると、前記ベーンの左、右側に位置した傾斜面に対して洗濯物および洗濯水との接触面積が広がるとともに、洗濯物が前記左、右側傾斜面７２、７４に沿って滑り落ちないよう、凹んだ曲面形状に形成され、前記左、右側傾斜面７２、７４が連結される上端部分は前記ドラムの回転中心Ｃに対して傾いた直線形状に形成され、また、前記ドラム５６の内壁に固定されるベーン７０の下端は前記ドラムの回転中心Ｃと水平な四角形状に形成されている。
【００１６】
したがって、前記ベーン７０は、上端は前記ドラムの回転中心Ｃに対して傾いた直線形状となっているのに対し、下端は前記ドラムの回転中心Ｃに対して水平な四角形状となっているため、前記左、右側傾斜面７２、７４と前記ベーン７０の取り付けられたドラム５６がなす角度（α、β）が先端から後端に行きながら変化される。
【００１７】
具体的に、前記ベーン７０は、図３ないし図５に示すように、先端から後端に行くにつれて前記左側傾斜面７２とドラム５６がなす角度（α）は線形的に減少され、前記右側傾斜面７４とドラム５６がなす角度（β）は線形的に増加されるように形成されているが、先端において前記左側傾斜面７２とドラム５６がなす角度（α）は８０°〜９０°、前記右側傾斜面７４とドラム５６がなす角度（β）は２０°〜３０°となり、後端において前記左側傾斜面７２とドラム５６がなす角度（α）は２０°〜３０°、前記右側傾斜面７４とドラム５６がなす角度（β）は８０°〜９０°となるように形成される。
【００１８】
図６は、本発明によるドラム式洗濯機の第２実施形態を示す側断面図であり、図７は本発明によるドラム式洗濯機のベーンの第２実施形態を示す斜視図であり、図８は図７のＤ−Ｄ線における断面図である。
図６に示すように、本発明によるドラム式洗濯機の第２実施形態は、洗濯がなされるドラム５６内壁に円周方向に沿って一定間隔をおいて突設され、前記ドラム５６の回転時に洗濯物を押し上げてから落下させることは勿論、洗濯水を汲み上げてから落下させるベーン８０を含めて構成される以外は、第１実施形態と同様に構成される。
【００１９】
ここで、前記ベーン８０は、図７および図８に示すように、上端が互いに連結されるように上方に傾くように形成された左、右側傾斜面８２、８４と、前記左、右側傾斜面８２、８４の前、背面を塞ぐ前、背面８６、８８とから構成され、その内部に洗濯水が循環できるよう下面が開放され、上端に洗濯水が循環されるように一定間隔をおいて孔８０ａが形成されるものの、前記ドラム５６が回転するとき洗濯水を汲み上げ得るように前記左、右側傾斜面８２、８４は凹んだ曲面形状に形成され、前記左、右側傾斜面８２、８４の連結部分の上端は曲線形状に形成される。
【００２０】
特に、前記ベーン８０は、前記ドラム５６が正方向または逆方向に回転されることによらずいつでも洗濯水を汲み上げるようにＳ字状に形成される。
したがって、前記ドラム５６およびベーン８０が回転し洗濯およびすすぎ行程が行われる場合、前記ベーン８０は、前記左、右側傾斜面８２、８４が凹んだ曲面形状からなっており、洗濯物が前記左、右側傾斜面８２、８４に容易にかけられることは勿論、洗濯物が前記左、右側傾斜面８２、８４に沿って滑り落ち難いので、より高くまで押し上げることができ、また、前記ベーン８０はＳ字状からなっており、洗濯物の以外に洗濯水も汲み上げてから落下させるので、洗濯およびすすぎの性能を向上させることができる。
【００２１】
このように構成された本発明によるドラム式洗濯機の第１実施形態の動作は、下記のようになる。
まず、洗濯機が作動すると、泡量が感知されて前記水槽５４とドラム５６内に設定された水位まで洗濯水が供給され、前記モータ５８の作動によって前記ドラム５６が正方向または逆方向に回転されながら洗濯およびすすぎ行程が行われる。
【００２２】
ここで、前記ドラム５６が回転するとき、前記ドラム５６内壁に取り付けられたベーン７０も同時に回転しながら前記ドラム５６の低部に置かれている洗濯物を円周方向に沿って一定高さまで押し上げてから前記ドラム５６の下部に落下させ、この落差による衝撃力と屈伸によって洗濯およびすすぎが行われるようにする。
【００２３】
このとき、前記ベーン７０は、前記左、右側傾斜面７２、７４が凹んだ曲面形状からなっており、洗濯物が前記左、右側傾斜面７２、７４に容易にかけられることは勿論、洗濯物が前記左、右側傾斜面７２、７４に沿って滑り落ち難いので、洗濯物をより高くまで押し上げ、洗濯およびすすぎの性能を向上させることができる。
【００２４】
また、前記ベーン７０は、上端が前記ドラムの回転中心Ｃに対して傾くように形成されているため、前記ドラム５６が正方向に回転しながら前記ベーン７０にかけられた洗濯物が前記ベーン７０の上端に沿って案内されて前記ドラム５６の後方側に移動されるようにし、一方、前記ドラム５６が逆方向に回転しながら前記ベーン７０にかけられた洗濯物が前記ベーン７０の上端に沿って案内されて前記ドラム５６の前方側に移動されるようにすることによって洗濯物が前記ドラム５６の水平方向に流動されるようにし、洗濯物の洗濯およびすすぎの性能を向上させる。
【００２５】
このように洗濯およびすすぎ行程が完了すると、前記モータ５８の作動によって前記ドラム５６が正方向に徐々に回転されながら前記ベーン７０にかけられていた洗濯物が前記ベーン７０の上端に沿って案内されて前記ドラム５６の後方側に移動され、続いて前記ドラム５６が高速に回転し洗濯物に含まれた洗濯水を遠心力によって前記ドラムの脱水孔５６ａから前記水槽５４側に排出させ、脱水行程を完了する。
【００２６】
このように前記ベーン７０によって洗濯物が案内されて前記ドラム５６の後方側に移動され、前記回転軸６２の近くに位置した状態で脱水行程が行われるので、洗濯物が偏心された状態で前記ドラム５６が高速回転しても偏心量を減らすことができ、偏心による振動や騒音を減らすことができる。
【００２７】
【発明の効果】
以上のように構成される本発明によるドラム式洗濯機は、洗濯物を押し上げてから落下させるベーンの左、右側傾斜面が凹状に形成されるので、ドラムの回転時洗濯物が前記ベーンに容易にかけられることは勿論、前記ベーンにかけられた洗濯物が滑り落ち難い。その結果、洗濯物を一定高さまで押し上げて洗濯物の流動性を増大させ、洗濯物および洗浄水との接触面積を増やし、洗濯およびすすぎの性能を向上させることができる。
【００２８】
また、本発明によるドラム式洗濯機は、前記ベーンの左、右側傾斜面の連結部分の上端が前記ドラムの回転中心に対して傾くように形成されるので、前記ドラムが回転するとき前記ベーンにかけられた洗濯物が前記ベーンの上端に沿って案内されて前記ドラム内部で前後方向に流動されるとともに前記ドラム内部に均一に分布され、洗濯およびすすぎの性能が向上され、また、脱水時洗濯物を前記ドラムの後方側に移動させて偏心量を減らし、振動や騒音を低減させることができる。
【００２９】
また、本発明によるドラム式洗濯機は、ベーンの左、右側傾斜面が凹状に形成されるとともに、全体的にＳ字状に形成されるので、前記ドラムが回転するとき洗濯水を汲み上げてから落下させて洗濯水を循環させ、洗濯およびすすぎの性能を向上させることができる。
