Description
タブ4は、キャビネット2の上側とバネ16で連結され、キャビネット2の下側と緩衝作用を行うダンパー17で連結される。
まず、洗い行程が始まると、ドラム6に積み置かれた洗濯物の布量にしたがって洗濯水が洗剤と共にタブ4及びドラム6に供給され、駆動装置8の駆動力によりドラム6が回転される。すると、洗剤の乳化作用及び洗濯物とドラム6と水流間の摩擦力などが複合的に作用しながら洗濯が行われる。
この時、使用者の設定によってヒータ20が作動すると、タブ4及びドラム6に供給された洗濯水が加熱され洗濯温度が高まるので、洗濯物の汚れはより有効に落ちる。
前記布濡れ段階では、前記洗濯槽の洗濯水が前記洗濯槽の上方部位へ輸送することにより循環される。
前記タンクに供給された洗濯水を前記ヒータにより加熱して蒸気を生成する蒸気発生段階と、前記蒸気発生段階で生成された蒸気が前記洗濯槽に噴射される蒸気噴射段階とを含む。
好ましくは、前記蒸気発生段階は前記ヒータが設定時間の間作動される。
前記給水段階は、前記洗濯段階で前記洗濯槽に洗濯水が再給水される時に行われる。
本発明に係る蒸気噴射式洗濯機の洗濯方法には多数の実施例があり得るが、以下では最も好ましい実施例について説明する。ただし、蒸気噴射式洗濯機の洗濯方法をなす基本的な構造は上に述べた従来の技術におけると同様なのでその詳細は省略するものとする。
図6は、本発明の第1実施例による蒸気噴射式洗濯機の洗濯方法において洗濯段階を示すフローチャートであり、図7は、本発明の第1実施例による蒸気噴射式洗濯機の洗濯方法において蒸気供給段階を示すフローチャートである。
また、上記蒸気供給段階では、図7に示すように、まず、タンク66に洗濯水が供給される給水段階(S20〜S26)を行う。
この時、ヒータ68が作動された後(S30)、タンク66の内部圧力が危険事故発生可能な臨界値である予め設定した圧力に達すると(S32)、ヒータ68が前記自動圧力スイッチ72によって停止される(S38)。
また、ヒータ68が作動した時間が、臨界値である設定時間になると(S36)、ヒータ68が停止する(S38)。
上述した蒸気供給段階は、洗い行程の他にすすぎ行程中にも繰返し行われる。
本発明の第2実施例による蒸気噴射式洗濯機の洗濯方法を図3ないし図5、及び図8を参照して説明する。
図8を参照すると、前記蒸気噴射段階では、まず、タンク66に一定水位の洗濯水を満たす給水段階(S50〜S56)が行われる。
つまり、洗濯槽52に洗濯水が供給されると同時に(S50)、給水路62と蒸気流路64が開放されて給水路62を通じてタンク66に洗濯水が満たされる(S52)。
