A washing machine includes a tub and a drum. The tub includes a first case and a second case welded to each other; a first coupling surface extending along a circumference of the first case and facing the second case; a second coupling surface extending along a circumference of the second case and coupled to the first coupling surface; and a coupling protrusion that protrudes from the first coupling surface toward the second coupling surface and that includes a protruding end portion welded to the second coupling surface. The coupling protrusion includes: a main coupling protrusion that extends along the first coupling surface; and an auxiliary coupling protrusion that is disposed radially outward of the main coupling protrusion and spaced apart from the main coupling protrusion and that defines a discharge opening configured to discharge washing water entered between the main coupling protrusion and the auxiliary coupling protrusion.

A laundry treating apparatus includes a cabinet. The laundry treating apparatus further includes a drawer provided to be ejected from the cabinet. The laundry treating apparatus further includes a tub provided inside the drawer, providing a space where water is stored. The laundry treating apparatus further includes a drum rotatably provided inside the tub, providing a space where laundry is stored. The laundry treating apparatus further includes an inlet provided in the tub, inserting laundry into the drum. The laundry treating apparatus further includes a support unit provided between the tub and drum to prevent one surface of the tub having the inlet from being bent toward the drum and ejected to the outside of the tub through the inlet.

Disclosed are a lifter having an improved structure to improve washing performance and a washing machine having the lifter. The washing machine includes a drum and a lifter coupled to the inside of the drum, wherein the lifter is provided in the form of a closed curve in which a space is formed at a central portion thereof.

A laundry machine includes first and second washing units including first and second tubs, respectively. First and second drums are mounted inside the first and second tubs, and first and second drive units drive rotations of the first and second drums around first and second rotational shafts, respectively. The second washing unit is arranged above the first washing unit and has a smaller laundry treating capacity than the first washing unit. The first rotational shaft is not parallel to the second rotational shaft. A first recess projects downward from a rear lower surface of the second tub and is configured to heat wash water in the second tub. A metal plate member is provided on an outside lower surface of the second tub, and partially extends to the rear of the second tub to expose a bottom surface of the first recess.

A laundry treating appliance having a rotatable basket that defines a treating chamber, a tub for mounting the rotatable basket, a drive assembly mounted to the tub for rotating the basket and a drive motor mounted to the tub for driving the drive assembly. The tub has a lower region comprising a central cavity and a second cavity. The drive assembly is nested in the central cavity and the drive motor is nested in the second cavity for reducing the vertical stack of tub and the motor.

A laundry appliance includes a rotating drum that receives laundry to be treated. A motor rotates a drive shaft about a vertical axis and engages the rotating drum at a base. A coupler is disposed within an upper portion of the base and that rests upon the drive shaft to transfer rotational forces from the drive shaft to the drum. A lower portion of the base engages an outer surface of the shaft to resist moment forces that are exerted against the drive shaft in an off-axis direction relative to the vertical axis.

A washing machine including a bearing housing to rotatably support a shaft configured to drive the drum and insertable into the tub, the bearing housing including a stator coupling portion to which a stator of a drive motor configured to rotate the shaft is coupled, and a plurality of leg portions spaced apart along a circumferential direction of the stator coupling portion. The plurality of leg portions include a leg plate including a first end connected to the stator coupling portion and a second end formed to extend along a radial direction of the stator coupling portion from the first end, a connection portion provided to connect between adjacent first ends of the plurality of leg portions, a separation space formed between second ends of the plurality of leg portions, and an outer rib formed along an edge of the leg plate and the connection portion.

A double-drum washing machine comprises a first outer drum and a second outer drum which are respectively provided with a drum inside, wherein the second outer drum is provided with a connecting part which protrudes out of a surface of the second outer drum and which is molded integrally, the connecting part extends towards the first outer drum along a radial direction from the surface of the second outer drum, and an end part of the connecting part is in detachable connection with the first outer drum. Double drums of the double-drum washing machine are connected to be almost integrated, therefore, auxiliary fixed parts are reduced, and the connection between double drums is more stable, reliable and more compact, the vibration of the double-drum washing machine is effectively reduced during operation, the noise pollution of the double-drum washing machine is reduced, and additional counterweight is not required.
