Abstract: A washing machine includes a washing tub, a dewatering tub arranged rotatably in the washing tub, a housing to accommodate the washing tub, a suspension to suspend the washing tub from the housing substantially in a vertical direction, and a damper to connect the washing tub to the housing. The damper includes a translational damper to apply a damping force in a direction of translation, and a first rotational damper and a second rotational damper respectively connected to opposite ends of the translational damper while securing a degree of freedom substantially in the vertical direction of the translational damper, and to respectively apply the damping force in a rotating direction. The first rotational damper is arranged on a lower portion of the housing to be rotatable about a first rotary axis substantially in the vertical direction. The second rotational damper is arranged on a bottom of the washing tub to be rotatable about a second rotary axis substantially in the vertical direction.

Abstract: A washing machine includes a damper to reduce a vibration. The damper includes a damper frame and a rod respectively supported by the tub and the housing. The rod may move relative to the damper frame in an axial direction by being inserted into a support portion of the damper frame. A rotation movement member is movable in the axial direction by rotating with respect to the damper frame. A friction member is disposed between the support portion and the rotation movement member and applies a friction force to the rod. A switching unit switches, by rotating the rotation movement member, the damper between a first state in which the friction member is movable together with the damper frame with respect to the rod and a second state in which the friction member is movable together with the rod with respect to the damper frame.

Abstract: The present disclosure is to deal with a case in which waterproof clothes, etc. are included in laundry. A washing machine 1 having a dehydration function may include a drum 20 rotatably accommodated in a tub 10, a water-level sensor 60 configured to detect a water level of water IW collected between the tub 10 and the drum 20, a circulation pump 80 configured to supply water to the inside of the drum 20 and to circulate water collected in the inside of the tub 10, and a control apparatus 70 configured to perform a dehydration process. The control apparatus 70 may include a dehydration course decider 74 configured to decide a dehydration course based on a change in water level of water IW collected between the tub 10 and the drum 20 by driving of the circulation pump 80.
