Abstract

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.
