Abstract: A washing machine including: a cabinet; a tub mounted inside the cabinet to receive washing water; a rotating drum mounted inside the tub to load laundry therein; and an injection unit to inject washing water inside of the rotating drum. The injection unit includes: a plurality of nozzles spaced away from each other to inject washing water inside of the rotating drum at different positions; and a connector configured to include a plurality of passages so that a flow path of washing water diverges into the plurality of nozzles. Washing water may be injected by the spaced nozzles over a wide area inside the drum.

Abstract: A washing machine includes a cabinet; a tub which is disposed in the cabinet and in which washing water is stored; a rotating tub that is disposed in the tub and accommodates laundry; a spray unit configured to spray washing water into the rotating tub; and a fixing unit to which at least a portion of the spray unit is coupled and which includes a mounting structure provided at at least a portion of a circumferential direction of the fixing unit so as to fix the spray unit. The mounting structure in which a spray unit can be fixed by a fixing unit provides that movement of the spray unit can be prevented when a washing machine operates and the spray unit can be assembled in a desired position of the washing machine.

Abstract: A washing machine includes a cabinet having an opening, a door to open and close the opening, and a locking unit to selectively restrict an operation of the door when the door is closed. A position of the door is adjusted through this configuration to stably close the opening and to prevent the door from being undesirably opened, and thus it is possible to improve washing efficiency. Further, a front structure of the opening may be improved, and thus laundry may be easily put in or taken out.

Abstract: A washing machine including a tub, a spin basket rotatably mounted in the tub, a pulsator rotatably mounted in the spin basket and having a pulsator hub part extending downward from a center portion of the pulsator, a driving device to generate rotational force, a wash shaft to transmit the rotational force generated from the driving device to the pulsator, and a buoyancy clutch upwardly and downwardly movably mounted to the pulsator hub part and configured to move up and down by buoyancy. The buoyancy clutch is configured to rotate together with the pulsator. When the buoyancy clutch moves down, the spin basket is engaged with the buoyancy clutch and receives the rotational force.

Abstract: A washing machine includes a wash tub in which wash water is stored, a detergent supply device to supply detergent into the wash tub, and a water supply hose to supply the wash water from an external water supply source to the detergent supply device and subsequently into the wash tub. Movement of the wash water through the water supply hose is carried out by a hydraulic pressure of an external water supply source in an entire region of the water supply hose.

Abstract: Disclosed herein is a washing machine in which a balancer is directly mounted on a body of an inner tub without a front surface part of the inner tub. The washing machine includes an outer tub to store water, a body formed in a cylindrical shape provided with an opening at one surface thereof and provided in the outer tub, and a balancer connected to an inner diameter part at the opening of the body to reduce unbalance of the body generated during rotation of the body and to reinforce the body.

Abstract: Disclosed are a drain device having a drain filter, which causes foreign substances contained in washing water to be effectively filtered out by a filter chamber to prevent the foreign substances from flowing into a pump chamber, and allows the washing water to smoothly flow in the filter chamber to use the drain filter for a long time, and a washing machine having the same. The washing machine includes a housing provided with a washing chamber; and a drain device including a filter chamber provided with a filter member installed therein filtering out foreign substances from washing water in the washing chamber, and a pump chamber connected to the filter chamber to forcibly discharge the washing water. The filter member has a sectional area gradually increased toward the pump chamber and is provided with an end terminal separated from an inlet of the pump chamber by a designated distance.

Abstract: The washing machine includes a rotating tub arranged to be rotatable about a shaft. A first mass member is mounted to the rotating tub so as not to be moved relative to the rotating tub in a circumferential direction of the rotating tub. The first mass member serves to apply load imbalance to the rotating tub upon rotation of the rotating tub. Also, a second mass member is arranged to be movable in the circumferential direction of the rotating tub. The second mass member serves to compensate for load imbalance of the rotating tub upon rotation of the rotating tub.

Abstract: Disclosed herein is a washing machine including a pair of tubs disposed in a main body and a detergent supply device to supply any one of the pair of tubs. A first detergent storage part, into which a first detergent is put, and a second detergent storage part, into which a second detergent is put, disposed above the first detergent storage part are provided in the detergent supply device, thereby reducing a width of the detergent supply device.

Abstract: A washing machine having balancers and a method of controlling the same is provided. The number of rotations of a motor is maintained at a designated number before excessive vibration of a tub occurs for a designated time in order to prevent excessive vibration of the tub before balls reach a balancing position. The method includes sensing the number of rotations of a motor; determining whether or not the sensed number of rotations of the motor reaches a designated number of rotations by comparing the sensed number of rotations of the motor with the designated number of rotations; and controlling the motor such that the number of rotations of the motor is maintained at the designated number of rotations when it is determined that the sensed number of rotations of the motor reaches the designated number of rotations.

Abstract: A washing machine including a tub to retain wash water, a spin basket rotatably installed in the tub, a pulsator rotatably installed in the spin basket, a drive unit to generate rotary power and transmit the rotary power to the pulsator, and a float clutch elevatably installed at the pulsator to selectively transmit the rotary power to the spin basket when elevated by buoyancy. The float clutch includes guide protrusions provided at an upper surface thereof to allow the float clutch to be elevatably installed at a lower portion of the pulsator, and the pulsator includes guide grooved provided at a lower surface thereof, the guide protrusions being elevatably installed in the guide grooves. Since the float clutch receives rotary power at a position spaced apart from the shaft installation portion of the pulsator, the rotary power is prevented from being concentrated on the shaft installation portion.

Abstract: A washing machine and a control method thereof are disclosed. The washing machine has a plurality of washing tubs to clean laundry in different ways classified according to capacity and types of clothing. Different washing tubs simultaneously stop operations or are stopped at different times spaced apart from each other by a predetermined time, although washing tubs have different washing conditions (e.g., different input times of laundry, different amounts of laundry, different washing courses, etc.) when laundry is cleaned using the washing tubs.

Abstract: A drain pump including a case including a mounting bracket; a first connection member mounted to the mounting bracket to be spaced from the cabinet; a second connection member inserted in the first connection member; and a fastening member passed through the cabinet and inserted in the second connection member so that the case is mounted to the cabinet. Since the first connection member is spaced from the cabinet, the second connection member can be prevented from being damaged by vibration of the drain pump.
