Rotary actuator assembly, household appliance and control method for household appliance

A rotary actuator assembly capable of implementing manual and automatic mode switching, comprising a to-be-rotated object and a rotary actuator matched with the to-be-rotated object, wherein the rotary actuator comprises an output shaft and a driving mechanism for driving the output shaft to rotate;

• the to-be-rotated object is provided with a shaft hole matched with the output shaft;
• a driving structure and an abutting structure that cooperate in a circumferential direction are arranged in the output shaft and the shaft hole of the to-be-rotated object, and propping surfaces and abutting surfaces that allow the output shaft to rotate to push the to-be-rotated object to move are formed between the driving structure and the abutting structure;
• and
• the total length of the driving structure and the abutting structure along the circumferential direction of the output shaft is less than the circumference of a circumferential surface where the driving structure and the abutting structure lie, so that a rotation space for allowing the to-be-rotated object to be manually operated to rotate is formed between the driving structure and the abutting structure.
