Abstract: A vibration-reducing washing machine and a vibration-reducing method therefor. The washing machine has an outer drum, a cabinet, a motor, a main control panel, a damper device, and a vibration detection and control module fixed to the washing machine and connected to the main control panel. The vibration detection and control module detects and calculates vibration data and generates a control signal. The method includes setting a fixed tolerance for washing machine vibration, detecting and calculating vibration data, and comparing the vibration data with the fixed tolerance, and when the detected vibration data exceeds the fixed tolerance, adjusting working parameters of the motor and adjusting a damping magnitude of the damper device until the vibration data detected subsequently is maintained within the range of the fixed tolerance.
