A washing machine comprises a main body and a weight mass base; a tub provided within the main body; a rotatable drum mounted in the tub; a motor to rotate the drum; and a weight mass base located at the bottom of the main body of a washing machine; wires, belts, straps or nets and the like wrapping around the tub and connecting tightly in tension to the clips of the frame in the main body to increase the main body's weight including the tub with laundry and water and the weight of the motor additionally and transfer the added weight to the weight mass base disposed at the bottom of the washing machine so as the total weight force becomes greater than the dynamic force generating vibration of the washing machine and suppresses the vibration of the tub and the drum more efficiently.

A laundry washing machine having an outer casing, a washing tub, a rotatable drum and at least one balancing ring rigidly secured to the rotatable drum. The at least one balancing ring includes a substantially toroidal, annular housing that is rigidly secured to the drum, and has a tubular structure so as to delimit a closed annular inner cavity. A number of balancing masses are accommodated in movable manner inside the annular inner cavity, preferably together with a damping liquid. The annular housing has a substantially frustoconical outer wall segment that is inclined by an angle () lower than 90 with respect to the midplane (P) of the annular housing, and a peripheral supporting structure that juts out outwardly from the substantially frustoconical outer wall segment to stably abut against the body of the drum.

A washing machine includes a machine housing, a water accommodation tub disposed in the machine housing; a washing tub assembly disposed in the water accommodation tub and including a washing tub; and a balance ring mounted to an upper end of the washing tub and having a lower end fitted in the washing tub.

A laundry treating apparatus includes a cabinet, a tub, a drum rotatably disposed inside the tub, an elastic member to connect, to the cabinet, a portion of the tub body above a horizontal line passing through a rotation center of the drum; first and second dampers to connect, to the cabinet, a portion of the tub body located below the horizontal line; and a third damper to connect, to the cabinet, a portion of the tub body located below the horizontal line. A first location is defined as one of left and right portions in the tub body relative to a vertical line passing through the rotation center of the drum, while a second location is defined as the other portion. The first damper and second damper are disposed at the first location. The third damper is disposed at the second location.

A laundry treating appliance is configured to treat laundry according to a cycle of operation. The laundry treating appliance comprises a chassis that defines an interior and has a front and rear with an access opening located in the front. A tub statically mounted to the chassis and defines a liquid chamber located within the interior and has at least one suspension opening. An exoskeleton is located within the liquid chamber and has a front support, a rear support, and stringers extending longitudinally to form a skeletal frame defining a frame interior. A rotatable drum is located within the frame interior. A suspension system is located within the interior and has at least one suspension component extending into the liquid chamber through the suspension opening and is operably coupled to the exoskeleton. A liquid dam retards liquid flow from the liquid chamber to the interior through the suspension opening.

The present invention relates to an apparatus for treating laundry, including a cabinet having an entrance for inserting laundry and a door opening and closing the entrance, a tub positioned in the cabinet and having an opening for allowing the laundry to pass through, a drum rotatably positioned in the tub to receive the laundry, a vibration insulating part maintaining a watertight seal by connecting the entrance and the opening, a balance weight positioned in a front side of the tub to increase a weight of the tub, and an annular passage part extending between the vibration insulating part and the balance weight, the annular passage part fixedly supported by the balance weight, the annular passage part having a plurality of nozzles spraying wash water into the drum through the vibration insulating part.

A balance weight mounting structure of a washing machine and a balance weight mounting device are disclosed. The balance weight mounting structure of a washing machine comprises a cabinet; a tub movably supported with respect to the cabinet; a drum rotatably supported in the tub; and a balance weight provided in the tub, increasing a weight of the tub, wherein the tub and the balance weight are welded by a welding device and fixedly fastened to each other.

Disclosed is a washing machine including: a plurality of nozzles provided in an inner circumferential surface of a gasket body to spray water into a drum; a pump configured to pump water discharged from a tub; a distribution pipe supplying the water, pumped by the pump, to the plurality of nozzles; and a circulation pipe connecting the distribution pipe and the pump, wherein the pump is disposed in one side of left and right sides with reference to the inlet port, wherein the circulation pipe is bent at least once, wherein the inlet port includes a first positioning protrusion protruding from an outer circumferential surface of an inlet pipe coupled to the circulation pipe, and wherein a first positioning groove allowing the first positioning protrusion to be inserted thereinto is formed at one end of the circulation pipe, and accordingly, misassembling of the circulation pipe may be prevented.

Disclosed is a washing machine including: a gasket, wherein the gasket includes a plurality of nozzles provided on an inner circumferential surface of a gasket body to spray water into a drum, and a plurality of port receiving pipes protruding from an outer circumferential surface of the gasket body and respectively communicating with the plurality of nozzles; a distribution pipe supplying water pumped by a pump to the plurality of nozzles; and a first balancer disposed at a front surface of a tub. At least a portion of the first balancer is spaced apart from the outer circumferential surface of the gasket body, and at least a portion of a transport conduit of the distribution pipe is disposed in a space between the first balancer and the gasket body, and accordingly, separation of the distribution pipe from the gasket is prevented.

Disclosed is a washing machine including: a gasket, wherein the gasket includes a gasket body, forming a passage between a laundry entry hole formed in a casing and an opening formed in a tub, and a plurality of nozzles spraying water into a drum; and a distribution pipe supplying water pumped by a pump to the plurality of nozzles, wherein the distribution pipe includes a transport conduit disposed on an outer circumferential surface of the gasket, wherein the gasket body is divided into a front body positioned on the side of the casing and a rear body positioned on the side of the tub, wherein the rear body includes an accommodating part in which at least a portion of the transport conduit is disposed, and accordingly, it is possible to prevent intervention between the distribution pipe and any other structure around the gasket.
