    • A method for sensing a type of an unbalance of a washing machine is provided. The method may include detecting a vibration amount of a tub using a multi-axis acceleration sensor; detecting a vibration amount of an rpm of a motor; and judging a type of an unbalance based on the vibration amount and the rpm vibration amount. The method may also include detecting a vibration amount of a tub at a plurality of positions of the tub using a plurality of multi-axis acceleration sensors; detecting a time difference of vibration occurrence at the plurality of positions, and thereby calculating a vibration phase difference; and judging a type of an unbalance based on the vibration amount detected at the plurality of positions and the vibration phase difference.
    • 提供一种用于感测洗衣机的不平衡类型的方法。 该方法可以包括使用多轴加速度传感器检测桶的振动量; 检测电动机的转速的振动量; 以及基于振动量和转速振动量判断不平衡的类型。 该方法还可以包括使用多个多轴加速度传感器来检测桶的多个位置处的桶的振动量; 检测所述多个位置处的振动发生的时间差,从而计算振动相位差; 以及基于在多个位置处检测到的振动量和振动相位差来判断不平衡的类型。
