According to a tub for a washing machine according to an exemplary embodiment of the present disclosure, a bottom portion, an outer side wall portion, an inner side wall portion, a water flow passage side wall are integrally formed by injection molding so as to form a water flow passage. An apparatus and a method of manufacturing the tub for a washing machine according to the exemplary embodiment of the present disclosure allow the bottom portion, the outer side wall portion, the inner side wall portion, and the water flow passage side wall to be integrally formed by injection molding.

Tub for washing machine, apparatus and method of manufacturing

Disclosed is a drum type washing machine, including a cabinet configured to form an outer appearance; a tub in the cabinet and configured to contain water therein; a drum in the tub and configured to accommodate laundry therein; and a lifter on the drum, configured to lift the laundry in the drum by upward rotation of the drum. The lifter comprises a lifter housing fixed to the drum and having an opening in one or more ends or sides thereof; and a lifter plate pivotally coupled to the lifter housing, the lifter plate being configured to hold water in the lifter during the upward rotation of the drum.

Drum-type washing machine

A washing machine includes an auxiliary washing unit. When an inner tank is rotated during a washing cycle or a rinsing cycle, washing water passing through the auxiliary washing unit impacts the laundry, which lies by trapping on a projection member, thereby improving washing performance.

Washing machine and washing method thereof

A washing machine includes an auxiliary washing unit. When an inner tank is rotated during a washing cycle or a rinsing cycle, laundry experiences direct impact from an impact projection member of a rotator assembly of the auxiliary washing unit, thereby improving washing performance by virtue of the rubbing caused by such impact.

A washing machine that includes an integrated tub/drum that holds water, accommodates laundry, and rotates; a hollow rotary shaft coupled to and passing through one surface of the integrated tub/drum; a water supply pipe and a water drain pipe in the integrated tub/drum and through a passage or opening in the hollow rotary shaft; a nozzle that extends upward from an end of the water supply pipe that is in the integrated tub/drum; and a water drain that extends downward from an end of the water drain pipe that is in the integrated tub/drum.

Washing machine

The present disclosure relates to a washing machine. The washing machine may include an integrated tub/drum that includes a drum main body that has a cylindrical shape or a truncated conical shape, stores water, holds or accommodates laundry and water, and rotates, and a plurality of hollow lifters that extend or protrude outward from a circumferential surface of the drum main body, and extend or protrude inward from the circumferential surface of the drum main body; a hollow rotary shaft that is coupled to and/or that penetrates one end and/or surface of the drum main body; and a drain pipe that is in the integrated tub/drum through the hollow rotary shaft, configured to discharge water from the drum main body and that may be collected by the lifter.

The present disclosure provides a drum type washing machine including a tub; a drum in the tub, configured to receive laundry; a motor coupled to the tub configured to rotate the drum; a spider configured to transfer torque from the motor to the drum, the spider including a shaft mount connected to a shaft of the motor, a plurality of arms radially extending from the shaft mount, and a plurality of supporting bars extending from the arms; a fixing member configured to fix or attach the drum to the spider; a plurality of slide guides in at least one of a side surface of the drum and the supporting bars; and a plurality of slide rails on another one of the side surface of the drum and the supporting bars, configured to be inserted into and/or slide along the slide guides, wherein the drum is movable in forward and backward directions of the tub.

Drum type washing machine

A drum type washing machine includes a main body including a cabinet, a drum in the cabinet having a rotational axis thereof parallel with the ground, and a motor configured to drive or rotate the drum; and an angle adjusting unit configured to adjust an angle of the main body from the ground and/or tilt the main body up to the angle, wherein the angle adjusting unit includes a base configured to support the main body and a driver on the base configured to tilt or raise the main body, and the angle adjusting unit is configured to tilt the main body at a rear lower end of the cabinet.

A drum type washing machine includes a main tub having a main drum that rotates to wash laundry, a sub tub separate from the main tub and having a sub drum that rotates to wash laundry, and a clutch unit including a motor that provides a rotational force to at least one of the main drum and the sub drum.

The present disclosure relates to a washing machine that may include an integrated tub/drum that has a cylindrical shape or a truncated conical shape, stores water, holds or accommodates laundry together with the water, rotates, and has an opening in one region of the integrated tub/drum; a drum cover that separably or removably covers the opening of the integrated tub/drum and is separable or removable from the opening; and a cover hinge that is at one side and/or edge of the opening of the integrated tub/drum, and rotatably supports one side of the drum cover.

A drying device for a washing machine includes a rotatable drum configured to house laundry items; a tub having the drum therein; a driving unit on the tub and connected to the drum, configured to drive the drum; a drying unit configured to store liquid water and circulate air in the drum to remove moisture from the laundry; and a control unit configured to control operations of the drying unit.

Drying device and method for drying laundry

A washing machine may include an integrated tub/drum configured to hold water, hold laundry, and rotate; a hollow rotary shaft coupled to an end and/or surface of the integrated tub/drum; a water supply pipe and a drain pipe in the integrated tub/drum and through a passage in the hollow rotary shaft; and a partition in the integrated tub/drum that is configured to separate the laundry from the water supply pipe and the drain pipe and that includes a plurality of holes.
