  • Patent number: 11196323
    Abstract: Provided are a programmable motor and a household appliance having the same. The programmable motor comprises a main body (21) and a driving device (22) comprising a reprogramming interface. When performing reprogramming on the programmable motor, the reprogramming interface communicates with a programming device to receive a motor parameter or a motor software program, to transmit the same to the driving device (22), and to update the motor parameter or the motor software program in the driving device (22). The method realizes rewriting of a motor software program and realizes reprogramming of a motor by directly inserting a programming device into a reprogramming interface of a driving device (22) without having to disassemble the driving device (22), thereby effectively reducing post-sale costs associated with a motor, and improving post-sale efficiency associated with the motor.

  • Patent number: 10676853
    Abstract: The present disclosure relates to a front-loading washing machine and an unbalance detection method and device thereof. The method comprises: when a drum operates at a low constant speed, detecting the torque of the drum and acquiring average torque values; when the roller operates at a constant acceleration speed, acquiring average torque values and a minimum value of the average torque values of the drum in real time; determining whether a difference between the average torque and the minimum value of the average torque values is greater than a preset unbalance threshold; and if so, determining that dynamic unbalance occurs on the drum; otherwise determining that no dynamic unbalance occurs on the drum. Because no sensor is needed for unbalance detection, cost and the detection difficulty are lowered, and damages to mechanical components due to collisions caused by dynamic unbalance when the drum operates at a high speed is avoided.

  • Patent number: 10171012
    Abstract: An air conditioner and a startup control method and system for an outdoor fan of the air conditioner. While in a process of charging a bootstrap capacitor in an actuator of a motor of the outdoor fan, an initial rotation state of the motor is detected in real time, and, when charging of the bootstrap capacitor is completed, startup of the motor is correspondingly controlled on the basis of the detected initial rotation state. This allows real time initial startup work state to be acquired when charging of the bootstrap capacitor is completed, thus allowing the motor to be started smoothly, increasing the success rate in starting the motor, and solving the problem of low success rate in starting the motor of an outdoor fan.
