A washing machine includes: an outer tub, an inner tub, a drain pump driven by an electric current to thereby drain water from the outer tub, a motor providing a rotational force to the inner tub, and a control unit controlling the drain pump and the motor. The control unit rotates the motor to increase a rotation speed of the inner tub to a preset first target speed during a sub spin-drying cycle to remove moisture from laundry in the inner tub, measure the current of the drain pump to measure an amount of water dehydrated from the laundry, measure, based on the current being increased and then decreased to or below a preset reference current, the rotation speed of the inner tub, and change a preset rotation time of the inner tub in a main spin-drying cycle according to the measured rotation speed of the inner tub.

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.
