Description
本実施形態の横軸周りのドラム10を備えた洗濯機では、洗い、すすぎ、脱水、および乾燥の各行程において、制御装置5がドラム10を夫々適正な回転速度にて駆動制御することで運転が実行される。そして、ドラム10内に収容された洗濯物による偏荷重などに起因してドラム10が振動し、弾性的に支持された水槽6は上下方向を主体に振動する。この水槽6の上下振動に応動して、サスペンション7では、水槽6に一体的に連結されたシャフト22を介してコイルばね25を伸縮させ、該シャフト24はシリンダ22内を上下方向に振動(往復動)する。上記コイルばね25は、その伸縮作用により振動を吸収して筐体1(底板1a)側への振動伝達を効果的に阻止する。
また、磁場発生装置を構成するコイルは2個設けて上下の2段配置としたが、例えば1個のコイル構成としても良く、この場合、当然該コイルの上下部に配置するヨークは2個とする磁場発生装置が構成される。
Claims (5)
