Provided are a method and apparatus for determining a blockage of a filter of a clothes dryer and a clothes dryer. The clothes dryer includes a motor. The method includes following steps. An actual rotational speed of the motor is acquired, and an electrical parameter corresponding to a rotational speed range to which the actual rotational speed belongs is determined as a first threshold corresponding to the actual rotational speed; an actual clothes volume in the clothes dryer is acquired, and the first threshold is corrected according to a correction coefficient corresponding to a clothes volume range to which the actual clothes volume belongs so that a second threshold is obtained; and an actual electrical parameter of the motor is acquired, and when it is detected that the actual electrical parameter is less than the second threshold, it is determined that the filter of the clothes dryer is blocked.

A washing machine appliance includes a tub and a rotatable basket therein. A method of operating the washing machine appliance may include rotating the basket at one or more first speeds prior to a water extraction operation and obtaining a first set of power measurements. The method may also include performing the water extraction operation. The water extraction operation may include rotating the basket at a second speed greater than the one or more first speeds. The method may further include rotating the basket at the one or more first speeds after the water extraction operation and obtaining a second set of power measurements. The method may also include determining a load type of the load of articles based on the first set of power measurements and the second set of power measurements.

A washing machine includes a drum, a pulsator, a motor including a stator, a first rotor connected to the drum and second rotor connected to the pulsator, an inverter circuit connected to the motor, and at least one processor configured to control the inverter circuit to selectively drive the motor based on a plurality of driving modes, the plurality of driving modes including a first driving mode to rotate only the first rotor, a second driving mode to rotate only the second rotor, or a third driving mode to rotate both the first rotor and the second rotor, control the inverter circuit to stop both the first rotor and the second rotor in response to changing from one of the plurality of driving modes to an other one of the plurality of driving modes, and control the inverter circuit to drive the motor based on the changed driving mode.
