Abstract
A vibration-damping component of a washing machine comprises a suspender, a spring, a sleeve and an electromagnetic sensing device. The electromagnetic sensing device comprises an electromagnetic coil and a magnet. The electromagnetic coil surrounds the sleeve, the magnet and the spring are arranged in the sleeve and are fixed on the suspender, the sleeve surrounds the suspender in a slidable manner, and the weight of clothing is determined through measuring magnetic flux change of the electromagnetic coil when the sleeve slides on the suspender. In addition, the magnet and the electromagnetic coil make relative displacement, inductance in the electromagnetic coil changes, and water inflow can be detected through detecting the inductance. When dewatering begins, the vibratory magnitude of an outer drum is determined through the inductance change of the electromagnetic coil, and the stability of dewatering operation of the washing machine can be controlled accordingly.
