Washing machine, roller load weight detection method thereof and computer readable storage medium

A washing machine, a drum load weight detection method thereof, and a computer readable storage medium, the method comprising: in response to a received detection instruction, executing a detection operation to obtain a physical signal when a motor of the washing machine is started, the detection operation comprising: controlling the motor to run to a target rotating speed in a motor starting process, the target rotating speed is lower than a resonance rotating speed interval of the washing machine; acquiring a physical signal of the motor in a motor starting process; and determining the load weight of the roller according to the physical signal and a preset association relationship. According to the scheme, vibration and even collision of the washing machine in the load detection process can be relieved or even avoided, the service life of the washing machine is prolonged, a sensor does not need to be additionally arranged, and cost reduction is facilitated. 一种洗衣机及其滚筒负载重量检测方法、计算机可读存储介质，所述方法包括：响应于接收到检测指令，执行检测
