A laundry machine includes a washtub, a drum, a gearbox, a seal, and a spin tube. The drum is disposed within and is configured to rotate relative to the washtub. The seal is disposed between the gearbox and the washtub. The spin tube extends from the gearbox and into the washtub. The spin tube is configured to transfer power from the gearbox to the drum to rotate the drum. The spin tube includes a shaft and a sleeve. The shaft is made from a first material. The sleeve is disposed about a section of the shaft. The sleeve is made from a second material that is less corrosive than the first material. An outer periphery of the sleeve engages the seal to prevent the ingress of water from the washtub into the gearbox.

A compact washing machine capable of improving detergency or reducing a washing time is provided. A drum 30 may be rotatably installed in a tub 20 installed in the inside of a housing 10 in the state in which an opening 12 is toward an opening of the drum 30. A pulsator 40 having a protrusion 45 extending in a radial direction may be rotatably installed on a bottom of the drum 30. During washing operation, a controller 60 may control a driving device 50 to rotate the pulsator 40 and the drum 30 in opposite directions.

In accordance with one aspect of the present disclosure, a washing machine includes a rotating tub configured to accommodate laundry, a water supply pipe configured to spray water over a surface of the laundry. The washing machine also includes a controller configured to execute a water supply cycle in which an operation of each of the rotating tub and the water supply pipe is controlled and water is supplied to the rotating tub. The washing machine further includes a wash cycle in which the laundry is washed and the controller executes a first cycle in which the rotating tub is rotated faster than a rotational speed in the wash cycle so as to discharge air contained inside the laundry before the wash cycle is terminated.

An apparatus and method for reducing displacement of a washing machine having a drum rotatable about an axis of rotation is disclosed. The washing machine comprises a chassis and a motor for rotation a drum. The drum is suspended from the chassis by a suspension. The suspension can comprise springs having six natural frequencies that can resonate at a rotational speed of the drum driven by the motor. The suspension system can be tuned such that resonant frequencies can be varied based upon rotational speed of the drum.
