Abstract: Disclosed herein is a washing machine capable of suppressing noise during spin-drying caused by a pressure difference in a tub. The washing machine may include a case comprising a laundry loading/unloading opening through which laundry is introduced, a door mounted at the case to open or close the laundry loading/unloading opening, a tub disposed inside the case, a drum rotatably disposed inside the tub, and an air inflow channel configured to guide air to flow toward a central portion of the drum in which a pressure decreases while the drum rotates.

Abstract: By improving the rigidity of a pulley while suppressing a weight of the pulley from increasing, excessive noises due to resonance can be reduced. A washing machine 1 includes a drum 9 rotatably disposed in the water tub 5. The washing machine 1 has a motor to rotationally drive a pulley 20, which is fixed to the drum 9, via an endless belt 13. The pulley 20 has a plurality of arms 23 radially extend from the boss 22 to support an outer wheel 21. The arm 23 has a variable cross-sectional portion 24 in which a section modulus against bending in an axial direction gradually decreases from the boss 22 to the outer wheel 21.

Abstract: The washing machine of the present disclosure includes an improved pulley for reducing the noise generated in the pulley. When the shaft is inserted into the shaft insertion hole, at least a part of the shaft is closely contacted with the shaft insertion hole to minimize the tolerance between the shaft and the shaft insertion hole, and the rotation shaft of the pulley and the center axis of the shafts may be made to coincide with each other, so that the noise generated by the rotation of the pulley can be effectively reduced. In addition, the spoke of the pulley includes the curved portion, thereby reducing the friction with the air and effectively reducing noise due to friction with air.

Abstract: A washing machine includes a water tub arranged in a case and a damper installed between the case and the water tub for damping vibrations of the water tub. The damper includes a plunger having one end supported on the case; a rod having one end supported on the water tub and the other end movably inserted to the plunger; a housing arranged to wrap around some of the plunger and the rod and including a friction member arranged between the housing and the plunger to contact an outer circumferential surface of the plunger; and a switching device configured to be in a first state in which the rod is coupled to the housing and able to move within the plunger along with the housing and a second state in which the rod is decoupled from the housing and able to move solely within the plunger.
