  • Publication number: 20240117561
    Abstract: 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.

  • Publication number: 20240060227
    Abstract: A washing and drying all-in-one machine and a control method therefor. The control method includes: when a washing and drying all-in-one machine enters a washing-drying linkage mode, measuring a remaining time of a washing program, and determining whether the remaining time is within a preset first time threshold value; and if so, a clothes dryer matching a drying program corresponding to the clothes and performing preheating, and after waiting for the washing program to end, the washed clothes being placed in the clothes dryer for drying. By the washing and drying all-in-one machine and the control method therefor, according to the remaining time of the washing program, the clothes dryer is started in advance to execute a drying program and is preheated, such that the entire washing-drying time consumption of the clothes is shortened, thereby improving the user experience, and meeting the increasing intelligent requirements of users.
