Washing appliance and a determination method for locking of a drum thereof. The washing appliance includes a drum for containing washing water, a drum motor for driving the drum to rotate and a locking structure for locking the drum. The drum motor drives the drum to rotate at a set power output, the locking structure generates a locking action for locking the drum, and until an output current of the drum motor is larger than a rated current, it is determined that the drum is locked by the locking structure; by comparing the output current of the drum motor with the rated current, until the output current of the drum motor is larger than the rated current. Whether the drum is locked by the locking structure or not can be accurately determined through the above determination, and therefore the drum locking accuracy can be improved.

An electronic starting switch assembly and control methods for a dryer having a split-phase induction motor. The assembly comprises a microcontroller unit (MCU) configured to execute a control method that dynamically manages the motor's operation by monitoring the forward magnitude current. The MCU determines a stabilized startup forward magnitude current and calculates a crossover condition, allowing for precise control of the motor's transition to single-phase operation by disconnecting the auxiliary winding and connecting the heater element based on real-time forward magnitude current analysis and processing. The system can also monitor for overload conditions indicative of rotor speed drops and can re-engage the auxiliary winding to maintain motor performance. The assembly includes a housing with a heat-sink for efficient thermal management and environmental protection of electronic components. The disclosed method provides a robust solution for efficient dryer operation by ensuring accurate control of motor start-up, running conditions, and overload protection.
