Abstract
【解決手段】洗濯物をタンブリングさせるべくドラムを50rpmで一定速度制御している状態で(S12)、回転速度をほぼ連続的にモニタし、速度変動が1.5rpm以下である状態が0.5秒続いたならば(S13〜S16)、洗濯物が集まった状況でなく適度に分散し易い状態であると判断して、回転速度を80rpmに上昇させる(S17、S18)。そして、検知した偏心荷重が所定値以下であれば(S19、20)、洗濯物が適度に分散した状態で遠心力によって張り付いたと判断する。一方、36m秒以下のごく短時間に急激な速度変動が検知された場合には(S22)、洗濯物がダンゴ状にかたまったものと判断しドラムを反転させてタンブリングを行う(S21)。

Description
ドラムを回転駆動するモータと、
脱水運転の立ち上げに際しドラム内の洗濯物がタンブリングされる第1回転速度でドラムが回転するように前記モータの一定速度制御が行われている状況下で、その回転速度の変動を検出する速度変動検出手段と、
該速度変動検出手段により検出された速度変動が所定値よりも小さくなったときに、洗濯物が遠心力によりドラム内周面に張り付くような回転速度までドラムの回転速度を上昇させるべく前記モータを制御する脱水立ち上げ制御手段と、
を備えることを特徴としている。
台座部10の上には、周面が略円筒形状で両端面がほぼ閉塞された外槽11が、外箱1の左右側面にそれぞれ端面が対向する状態で、左右両側上方から吊下げ支持する図示しない二本のスプリングと、前後方向に外槽11の下部を支え受ける二本のダンパ13とにより適度に揺動自在に保持されている。外槽11の内部には、多数の通水穴14aが穿孔された、周面が略円筒形状で両端面がほぼ閉塞されたドラム14が、左右方向に延伸する水平軸線Cを中心に回転自在に設けられている。このドラム14の内周面には、周方向に約120°間隔で3個のバッフル14bが取り付けられている。
