Disclosed herein is a washing machine having the structure to reinforce fastening bosses () formed on a front surface of a tub () to mount a balance weight (). The washing machine comprises a tub () having a gasket coupling part () to which a gasket () is coupled, a plurality of fastening bosses () formed on a circumference about a central axis of the tub () to secure a balance weight (), and a plurality of ribs () to reinforce the fastening bosses (), wherein at least one of the ribs () formed in an outer direction of the tub () around each fastening boss () is thicker than the ribs () formed towards the central axis of the tub ().

Washing machine

A washing machine is provided that includes a tub having an open front side and a closed rear wall, and a drum rotatably mounted within the tub. A portion adjacent to a gate part, which allows resin to be injected in an injection-molding process of the rear wall of the tub, is thicker than other portions, thereby improving inflow of the resin.

There are provided a conductivity sensor of a washing water, an installation construction of the conductivity sensor, and a method for controlling the washing machine, which are capable of controlling the washing machine by calculating a hardness of a washing water from a measured conductivity of the washing water.

Washing machine, conductivity sensor in washing machine, and controlling method of the same

A tub having a structurally strengthened rear wall and a washing machine with the same therein are disclosed. A washing machine includes a bearing housing having a flange part and a tub injection-molded with the bearing housing inserted into a wall thereof, the wall having a recessing part and a projecting part formed on an inner or an outer surface thereof along a circumferential direction, and a circumferential rib or a radial rib formed on the recessing part.

Tub having structurally strengthened rear wall and washing machine with the same therein

A drum washing machine is provided. The drum washing machine includes a tub that stores wash water therein, a drum rotatably mounted within the tub, a motor mounted in a rear of the tub, the motor having a shaft to rotate the drum, a bearing housing inserted into the tub having a hollow portion, which allows the shaft of the motor to pass therethrough, formed in a center thereof, a bearing secured to the hollow of the bearing housing, and an outlet hole that discharges gas or moisture generated in the bearing and a portion adjacent to the bearing outside of the bearing housing. The drum washing machine so constructed has enhanced durability, because it includes the outlet hole provided in the bearing housing where the shaft rotates that prevents moisture or water from remaining in the bearing housing.

Drum washing machine

A washing machine includes a tub made of plastic to store water therein and a drum rotatably installed in the tub to hold laundry therein. A shaft passes through the tub and connects to the drum to transmit driving power from a motor to the drum. A wall having a recessing part and a projecting part is formed on an inner surface or outer surface thereof in a circumferential direction. A bearing housing has a stator fastening part where the stator fastening part has a recessing part and a projecting part corresponding with the recessing part and the projecting part of the wall in a circumferential direction, and a stator of the motor is mounted on the stator fastening part and a rotor of the motor is connected to a rear part of the shaft and surrounding the stator.

A structure for cooling a motor of a washing machine is disclosed, which is suitable for improving cooling efficiency of the motor. A structure for cooling a motor of a washing machine, the washing machine provided with a motor assembly including a cylindrical rotor in an inner circumferential surface of a rotor housing, and a cylindrical rotor in an inner circumferential surface of the rotor, is provided with a plurality of holes on a lower surface of the rotor housing forming the stator; and a plurality of blades, each provided in one side of the hole.

Structure for cooling motor of washing machine

Damper for a full automatic washing machine including an upper buffering member fitted to an inside of an upper portion of a washing machine housing, an elastic member under the lower buffering member for elastic supporting of the lower buffering member, and a damper bar for passing through, and connecting the upper buffering member, the lower buffering member, and the elastic member in succession, for damping vibration and impact, wherein the upper buffering member has a through hole for passing the damper bar therethrough with an upper diameter equal to, or smaller than a diameter of the damper bar, a lower diameter greater than a diameter of the damper bar, and the lower buffering member has an extension projected upward from an upper surface, a plurality of reinforcing ribs in an upper portion of the extension, sloped guide ribs extended downward from a bottom thereof for preventing the lower buffering member from coming out of a top of the elastic member, and a hole for passing the damper bar therethrough, with an etched rugged inside surface for containing grease.
