Abstract: Provided is a washing machine capable of preventing laundry in a rotary tub from having pigment transfer or contamination due to wash water of an auxiliary washing tub. The washing machine includes a cabinet, a tub located in the cabinet and storing wash water therein, a main washing tub rotatably disposed in the tub and having a first washing space, and an auxiliary washing tub detachably mounted to the main washing tub and having a second washing space, wherein the auxiliary washing tub includes a drain path for guiding wash water of the second washing space to a space between the tub and the main washing tub.

Abstract: Disclosed is a washing machine including a drying function. Here, a height of a bottom end of a dryer disposed above a tub is lower than a height of a top end of the tub to have a space for integrating other devices having additional functions above the tub.

Abstract: Provided is a washing machine and control method thereof. The washing machine includes at least one magnet attached to an auxiliary wash tub detachable from a main wash tub; a switching device configured to output a detection signal when the at least one magnet approaches within a preset range to the switching device; and a controller configured to determine whether the auxiliary wash tub is installed based on whether the detection signal of the switching device is output, and control a component in the washing machine based on the determination of whether the auxiliary wash tub is installed.

Abstract: A dryer according to the present disclosure may be a dryer to which a heat pump system is applied, and may provide a structure in which constant temperature external air is suctioned and supplied to a drum to maintain constant performance of the dryer. An air supply unit configured to supply hot dry air to the drum is isolated from an inside of the main body such that internal air including a foreign material is not introduced into the air supply unit, and a suction port cover is separably coupled to the dryer such that a foreign material introduced with the external air is easily removed.

Abstract: Disclosed is a clothes dryer in which a cleaning structure of a heat exchanger is improved. The clothes dryer includes a main body, a drum rotatably provided in the main body, a heat pump including an evaporator, a compressor, a condenser, an expansion valve to supply hot and dry air into the drum, a condensate tank configured to receive condensed water generated from the heat pump, and a spray member configured to spray the condensed water in the condensate tank to the evaporator. The spray member includes an inlet portion through which the condensed water is introduced and a spray portion having a guide surface provided such that the condensed water introduced through the inlet portion is uniformly sprayed to a surface of the evaporator. At least a portion of the guide surface includes a curved surface having a constant curvature.

Abstract: A washing machine including a tub, a spin basket rotatably mounted in the tub, a pulsator rotatably mounted in the spin basket and having a pulsator hub part extending downward from a center portion of the pulsator, a driving device to generate rotational force, a wash shaft to transmit the rotational force generated from the driving device to the pulsator, and a buoyancy clutch upwardly and downwardly movably mounted to the pulsator hub part and configured to move up and down by buoyancy. The buoyancy clutch is configured to rotate together with the pulsator. When the buoyancy clutch moves down, the spin basket is engaged with the buoyancy clutch and receives the rotational force.

Abstract: A washing machine including a tub to retain wash water, a spin basket rotatably installed in the tub, a pulsator rotatably installed in the spin basket, a drive unit to generate rotary power and transmit the rotary power to the pulsator, and a float clutch elevatably installed at the pulsator to selectively transmit the rotary power to the spin basket when elevated by buoyancy. The float clutch includes guide protrusions provided at an upper surface thereof to allow the float clutch to be elevatably installed at a lower portion of the pulsator, and the pulsator includes guide grooved provided at a lower surface thereof, the guide protrusions being elevatably installed in the guide grooves. Since the float clutch receives rotary power at a position spaced apart from the shaft installation portion of the pulsator, the rotary power is prevented from being concentrated on the shaft installation portion.
