A washing machine according to an aspect of the disclosure includes: a tub to accommodate wash water; a drum inside the tub; a driving device configured to rotate the drum, the driving device including: a coupler configured to move between a first position and a second position to adjust a rotational speed of the drum, and a solenoid configured to move the coupler between the first position and the second position in response to an electric current flowing through the solenoid; a circulation pump configured to operate to circulate the wash water in the tub; and a controller configured to determine when the circulation pump is operating and to control the electric current flowing through the solenoid to move the coupler between the first position and the second position while the circulation pump is determined to be operating.

Washing machine and control method thereof

A washing machine according to an aspect of the disclosure includes: a drum; a tub accommodating the drum and storing water; a drum motor configured to provide a rotation force to the drum; a water supplier configured to supply water to the tub; a hot air supplier configured to supply hot air to the drum; a current sensor configured to output a current signal corresponding to a magnitude of current applied to the drum motor; and a controller configured to perform a washing operation while controlling the water supplier and the drum motor, and perform a drying operation while controlling the hot air supplier and the drum motor.

A washing machine for controlling optimal operating revolutions per minute (rpm) of a drain pump in a draining course and a dehydrating course includes a washing tub; a drain pump configured to drain water in the washing tub; a pump motor configured to operate the drain pump; an inverter circuit configured to supply a driving current to the pump motor to operate the drain pump; and a controller configured to control the inverter circuit to supply reference power to the pump motor in response to starting a draining course, determine reference revolutions per minute (rpm) based on average rpm of the pump motor during a preset period of time, and control the inverter circuit to operate the pump motor at the reference rpm in response to the determining of the reference rpm.

Washing machine and controlling method for the same

A clothes treatment apparatus for identifying a noise course in which abnormal noise occurs, the clothes treatment apparatus including: a frame forming a skeleton of a cabinet; a cover plate surrounding the frame to form an external appearance of the cabinet; a tub provided in the cabinet; a drum rotatably provided in the tub; a drum motor configured to rotate the drum; and a vibration sensor provided on the frame.

Clothes treatment apparatus and method of controlling the same

Disclosed herein is a clothing dryer. The clothing dryer includes a main body, a drum rotatably installed in the main body, a first motor configured to transmit a rotational force to the drum, a heat pump configured to heat air supplied to the drum and including an evaporator, a compressor, a condenser, and an expansion valve, a flow path connected to the drum to circulate air; and a second motor disposed in the flow path and configured to drive a fan to flow air.

Clothing dryer

A clothes care apparatus including: a main body including a clothes care room; a blower configured to form an airflow inside the clothes care room formed therein, and disposed between an upper part of the clothes care room and an upper part of the main body; and a duct configured to allow air inside the clothes care room to be introduced into the blower by the blower, and formed between a rear part of the main body and a rear part of the clothes care room, wherein the blower includes a blowing fan and a scroll to cover the blowing fan, and the scroll includes a flat portion formed to extend in a direction corresponding to an extension direction of the duct to guide the air into the blower.

Clothes care apparatus

A front-loading laundry-washing apparatus includes: a housing including a door in a front thereof for opening and closing; a washing tub rotatably supported inside the housing and shaped like a cylinder opened toward the door to load laundry therein; and a plurality of lifters arranged at predetermined intervals along a spinning direction of the washing tub on an inner circumferential surface of the washing tub, and including end portions extended toward a spinning center of the washing tub, wherein at least one lifter of the plurality of lifters is provided to alternate between a first state having a first height from the inner circumferential surface in a first section within a spinning section of the washing tub and a second state having a second height higher than the first height from the inner circumferential surface in a second section within the spinning section of the washing tub.
