A washing machine is provided. The washing machine includes: a display; a communication interface; and a processor, wherein the processor controls the display to display a user interface (UI) for overall control of the washing machine and a dryer connected to the washing machine in communication based on a first user input selecting a washing course being received, identifies a drying course of the dryer based on the washing course selected by the first user input and a control option selected by a second user input based on the second user input selecting one of the plurality of control options included in the UI being received, and control the communication interface to transmit information corresponding to the identified drying course.

A controlling method for a dryer is provided. The controlling method includes the steps of rotating a drum in a first direction and a second direction which is an opposite direction to the first direction by a motor, measuring the load of the motor and identifying the weight of drying materials based on the lower motor load among the load of the motor measured during rotation in the first direction and the load of the motor measured during rotation in the second direction.

A laundry drying machine includes: a cabinet, a drum rotatably disposed in the cabinet and configured to accommodate a target object, and an electric field generator spaced apart from the drum and configured to, based on power being applied to the electric field generator, generate an electric field. The electric field generator includes an anode electrode spaced apart from the drum, fixed to the cabinet, and configured to apply the electric field to the target object, a power supply unit configured to supply the power to the anode electrode, and a matcher configured to match a source impedance of the power and an impedance of a load side. The drum is configured to rotate at an agitating rotation speed in a state in which the power supplied to the anode electrode is stopped, the agitating rotation speed being (i) greater than 0 rpm and (ii) less than 50 rpm.

A method for controlling a laundry treating apparatus includes an air supplying step of supplying heated air to the drum through the heat exchange part and a first motion executing step executed while the air supplying step is in progress. The first motion executing step alternately executes a first acceleration mode of rotating the drum at an rpm inducing a centrifugal force equal to or greater than 1G along one of a clockwise direction and a counterclockwise direction and a first deceleration mode of rotating the drum at an rpm inducing a centrifugal force smaller than 1G in a direction equal to a rotational direction set for the first acceleration mode.
