Description
そこで、パルセータを回転させて布量を検知する精度をより高めることができる洗濯機を提供する。
この回転槽の内底部に配置されるパルセータと、
このパルセータを回転させるモータと、
このモータをトルク電流により駆動して、前記パルセータを回転させることで前記回転槽内の布量検知を行う制御部とを備え、
前記制御部は、布量検知を行う際に、前記パルセータを正転方向に回転させてから空走させ、続いて前記パルセータを反転方向に回転させてから空走させた期間内において前記モータの回転数を計測し、
前記パルセータを回転させる期間におけるトルク電流を、最初は相対的に大きい第1電流とし、その後は相対的に小さい第2電流に切り替える。
シャント抵抗4を各相に配置して、相電流を個別に検出しても良い。
閾値は700rpmに限ることなく、個別の設計に応じて適宜変更すれば良い。
また、モータ113を強制転流からトルク電流駆動に切り替える回転数も同様に、300rpmに限ることはない。
洗濯機の最大負荷量は、7kgに限らない。
第1,第2電流の具体数値も、両者の大小関係を維持した上で適宜変更すれば良い。
必ずしもベクトル制御で得られるq軸電流をトルク電流として制御する必要はない。
