| 20100175436 | Tub with overflow and washing machine having the same - Disclosed herein is a washing machine including an overflow defined through a portion of one side of an upper part of a tub and formed in the shape of a cutout and guide ribs protruding from the outer circumference of the tub to guide wash water drained through the overflow. The overflow is formed by cutting one side of the upper part of the tub, so that the washing machine has a simple overflow structure. | 07-15-2010 |
| 20100175437 | Coupling for washing machine and washing machine having the same - Disclosed is a washing machine including a tub; a dehydration basket provided in the tub; a pulsator provided in the dehydration basket; a dehydration shaft to transmit rotary force to the dehydration basket; a wash shaft to transmit rotary force to the pulsator; a driving motor to generate driving force to be transmitted to the dehydration shaft and the wash shaft; and a power conversion device to transmit the driving force of the driving motor simultaneously or selectively to the dehydration shaft and the wash shaft, the power conversion device including a clutch device, and a coupling configured to be pressed in one direction by the clutch device to transmit the driving force of the driving motor to the wash shaft and the dehydration shaft simultaneously and pressed in the other direction by the clutch device to transmit the driving force of the driving motor to the dehydration shaft only. | 07-15-2010 |
| 20100175727 | Washing machine - An automatic washing machine includes a remaining water discharging passage to drain remaining water from a pump case by connecting a drain line with an inner part of the pump case. | 07-15-2010 |
| 20100177494 | Control panel assembly and washing machine having the same - The control panel assembly includes a control panel provided with at least one hook, a guide member disposed at the inside of the control panel and provided with at least one hook reception part corresponding to the at least one hook, and an electronic component fixed to the inside of the guide member. | 07-15-2010 |
| 20100186459 | WASHING MACHINE HAVING BALANCER - A washing machine that has at least one balancer that increases durability by reinforcing the strength of the balancer and is installed on a rotating tub in a rapid and convenient way. The balancer includes first and second housings that have an annular shape and are fused to form a closed internal space, and the first housing including at least one support for reinforcing the strength of the balancer. A spin tub includes an annular recess corresponding to the balancer so as to be coupled with the balancer. The support protrudes from the first housing and comes into contact with a wall of the recess and guides the balancer to be maintained in the recess in place. The supports are integrally molded to the first housing at predetermined intervals along at least a first wall of the first housing. | 07-29-2010 |
| 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 |
| 20100269547 | Washing machine having balancer - A washing machine that has at least one balancer that increases durability by reinforcing the strength of the balancer and is installed on a rotating tub in a rapid and convenient way. The balancer includes first and second housings that have an annular shape and are fused to form a closed internal space, and the first housing including at least one support for reinforcing the strength of the balancer. A spin tub includes an annular recess corresponding to the balancer so as to be coupled with the balancer. The support protrudes from the first housing and comes into contact with a wall of the recess and guides the balancer to be maintained in the recess in place. The supports are integrally molded to the first housing at predetermined intervals along at least a first wall of the first housing. | 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 |
| 20110041352 | Clothes dryer - A clothes dryer having a preheating unit preheating drawn air is provided. The clothes dryer includes a main body, a drying tub rotatably mounted to receive an object to be dried, and a hot air duct supplying hot air into the drying tub. The hot air duct includes a heating unit heating drawn air, and a hot air supply unit connecting the heating unit with the drying tub, thereby forming a path for heated air. The heating unit includes a first heating unit having a heater part generating heat, and a second heating unit surrounding an entrance and outer walls of the first heating unit, thereby forming a path for the air flowing to the first heating unit. The second heating unit includes one or more preheating fins formed on the first heating unit to contact the air flowing in the second heating unit. | 02-24-2011 |
