Abstract: A washing machine includes a water tank, a washing tub, a pulsator, a drive motor, a drive shaft, a dewatering shaft that rotates about the same axis of the drive shaft and spins the washing tub, a coupler that is mounted to move up and down along the dewatering shaft and transmits the torque of the drive motor to the dewatering shaft, a solenoid module that moves the coupler upward in a lengthwise direction of the dewatering shaft so as to cut off torque from the drive motor to the dewatering shaft or transmit the torque to the dewatering shaft, when a magnetic field is generated by applying an electric current to a coil, and a coupler guide that rotates itself or fixes the position of the coupler, by coming into contact with the coupler when the coupler moves upward in the lengthwise direction of the dewatering shaft.

Abstract: A control method for a washing machine includes: a mode change step in which the configuration of a coupler is moved by operating a solenoid module in such a way that a drive shaft for spinning a pulsator and a dewatering shaft for spinning a washing tub are axially coupled or decoupled; and a mode check step in which a drive motor for rotating the drive shaft is operated and the load of current outputted to the drive motor is sensed, the mode check step comprising a coupler setting step in which, if the load of current outputted to the drive motor does not satisfy a set load value, the solenoid module is operated to reposition the coupler.

Abstract: A shoe care device includes an inner cabinet, an air supply device that is configured to blow air to an accommodated space of the inner cabinet and includes a plurality of dehumidifying materials separate from one another, and a controller configured to control the air supply device. The air supply device includes a connection path configured to circulate air between an inlet and an outlet of the inner cabinet, and a regeneration path branched from the connection path and configured to guide air having passed through at least one of the dehumidifying materials to a portion of the air supply device other than the inlet. The controller is configured to control the air supply device to selectively open and close at least one of the connection path or the regeneration path based on whether or not at least one of the dehumidifying materials is heated.

Abstract: A method of controlling a washing machine includes rotating a motor for driving an inner shaft in a first direction, and aligning a clutch to a reference position corresponding to one of a maximum lowered position and a maximum raised position. The motor is rotated by a preset reference alignment angle in a second direction to align the clutch from the reference position to a starting position corresponding to one of an upper limit and a lower limit of a preset agitating control section. The upper limit of the agitating control section is spaced downward by a first distance from the maximum raised position, and the lower limit of the agitating control section is spaced upward by a second distance from the maximum lowered position. The motor is rotated by a starting alignment angle set according to a displacement of the clutch ranging from the starting position to a target position corresponding to the other one of the upper limit and the lower limit so that the clutch is moved from the starting position to the target position.
