| 20080276657 | Drain device and washing machine having the same - 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. | 11-13-2008 |
| 20100095713 | Drain pump and washing machine having the same - 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. | 04-22-2010 |
| 20100269266 | Washing machine and method for controlling the same - 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. | 10-28-2010 |
| 20100275381 | Washing machine and method for controlling the same - A washing machine and a method of controlling the same are disclosed. If two washing tubs simultaneously perform the dehydration, unbalanced positions of the first and second washing tubs are checked. The method controls dehydration rotation speed or dehydration rotation direction of each washing tub to adjust a difference in unbalanced position angle between two washing tubs, thereby reducing vibration. If dehydration is performed in one washing tub, the method prevents the other washing tub performing no dehydration process from entering the dehydration process. | 11-04-2010 |
| 20100275386 | Washing machine and method of controlling the same - A washing machine which prevents wash water in a plurality of tubs from being simultaneously drained, and a method of controlling the washing machine. The washing machine includes a plurality of tubs, a plurality of drain devices to discharge wash water in the plurality of tubs to the outside, and a control device connected to the plurality of tubs to selectively drain the wash water in the plurality of tubs. | 11-04-2010 |
| 20100287712 | Washing machine and control method thereof - Disclosed herein are a washing machine having a plurality of washtubs and a control method thereof. In the washing machine having a plurality of washtubs, if it is determined that a washtub that is not in operation is present, dozens of liters of water used in a washtub that is in operation are moved into and stored in the non-operating washtub rather than being discharged to the outside. The moved water may be utilized in a following washing or rinsing stage of the washtub, or a washing or rinsing stage of the other washtub. | 11-18-2010 |
| 20110041258 | Washing machine and method to control the same - A washing machine having a plurality of washing units to separately wash laundry according to quantity and type of the laundry, and a method to control the same. In the washing machine having the plurality of washing units to separately wash laundry having different quantities and types, when the plurality of washing units are being simultaneously operated, a current load value of one of the washing units is detected through monitoring of a power line, to thereby determine the operation state of the washing unit. Therefore, the operation of the other washing unit may be controlled so that the power limit is not exceeded. As a result, the plurality of washing units may be operated simultaneously within the range of allowable power capacity of the installation place of the washing machine. | 02-24-2011 |
| 20110041560 | Washing machine - Disclosed herein is a washing machine having an upper washing unit and a lower washing unit. The upper washing unit is connected to the lower washing unit through connection parts protruded upwardly from the upper end of the lower washing unit. | 02-24-2011 |
| 20110041563 | Washing machine and outer tub supporting structure thereof - Disclosed herein are a washing machine which minimizes the number of dampers and effectively prevents vibration, and an outer tub supporting structure thereof. The washing machine includes a housing forming an external appearance of the washing machine, an outer tub provided in the housing to store water, an inner tub rotatably mounted within the outer tub, a driving device including a rotary shaft passing through the outer tub and connected to the inner tub to rotate the inner tub, a bearing surrounding the rotary shaft and fixed to the outer tub to prevent rotation of the outer tub during rotation of the rotary shaft, a bearing housing formed on the outer tub such that the bearing is mounted within the bearing housing, and a damping unit provided with a first end supporting the bearing housing and a second end fixed to the washing machine housing to reduce vibration of the outer tub. | 02-24-2011 |
| 20110041565 | Washing machine, inner tub of washing machine and balancer connection and assembly method thereof - 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. | 02-24-2011 |
| 20110041567 | Washing machine - 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. | 02-24-2011 |
| 20110094270 | Washing machine and balancer thereof - 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. | 04-28-2011 |
| 20110154865 | Detergent supply device and washing machine having the same - A washing machine includes a wash tub in which wash water is stored, and a water supply hose to supply the wash water 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. | 06-30-2011 |
