Description
本実施の形態によれば、ドラム22内での洗濯物の布絡み等に起因して回転体24に掛かる負荷が所定の大きさを超えた場合に、分散制御が行われて回転体24に掛かる負荷が軽減される。これにより、駆動モータ100がロックすることを抑制できる。
図11および図12は、変更例1に係る、駆動部30Aの構成を示す断面図である。図11は、駆動部30Aの駆動形態が、二軸駆動形態に切り替えられた状態を示し、図12は、駆動部30Aの駆動形態が、一軸駆動形態に切り替えられた状態を示す。
上記実施の形態では、左右の回転時における駆動モータ100の回転数が閾値以下である場合に分散制御が行われた。即ち、駆動モータ100の回転数に基づいて回転体24に掛かる負荷が大きいか否かの判定が行われた。しかしながら、これに限らず、たとえば、駆動モータ100に流れる電流を検出する電流センサが設けられ、駆動モータ100に流れる電流の大きさが所定の閾値以上となった場合に分散制御が行われてもよい。即ち、駆動モータ100に流れる電流の大きさに基づいて回転体24に掛かる負荷の大きさの判定が行われてもよい。

ことを特徴とするドラム式洗濯機。 - 請求項2に記載のドラム式洗濯機において、
前記制御部は、前記駆動モータを右回転および左回転させ、双方の回転において前記駆動モータの回転数が前記閾値以下である場合に前記軽減制御を行う、
ことを特徴とするドラム式洗濯機。 - 請求項1ないし3の何れか一項に記載のドラム式洗濯機において、
前記駆動部は、前記ドラムと前記回転体とを互いに異なる回転数で回転させる第1駆動形態と、前記ドラムと前記回転体とを互いに等しい回転数で一体的に回転させる第2駆動形態に切り替え可能であり、
前記制御部は、前記第2駆動形態において、前記ドラムが、前記ドラム内の洗濯物に作用する遠心力が重力より大きくなる回転数で回転するように、前記駆動モータを回転させる、
ことを特徴とするドラム式洗濯機。
