<p>The present invention relates to a method for judging the weight of clothes for a series motor drum washing machine. The method comprises the following steps: sending a preset control signal by a main chip of a circuit board of a washing machine; driving a motor up to a preset rotation speed, wherein the preset rotation speed is split into several segments; at different rotation speeds, collecting output signals of the circuit board and input signals fed back by the motor, wherein the output signal comprises the output power of the motor, and the input signal comprises the number of feedback pulses of the motor, the time of different phases, the mass of eccentric loads that exist in a drum, etc.; and calculating the weight of the clothes in the current drum according to a mathematic model which is fitted when designing. The present invention realizes the effect that the series motor drum washing machine has a function of judgment of the weight of the clothes and can automatically select a way to wash clothes, improves the dewatering performance, and optimizes the procedure for washing clothes.</p> |
