20120204607 | BUBBLE GENERATING DEVICE AND WASHING MACHINE HAVING THE SAME - A bubble generating device and a washing machine equipped with the bubble generating device. The washing machine includes a water tub into which water is introduced, a bubble generating device to generate bubbles and supply the bubbles into the water tub, a pump to suck water from the water tub and supply the water into the bubble generating device, and a connecting pipe having an end connected to the bubble generating device and the other end connected to the water tub. The other end of the connecting pipe is located above a water level in the water tub. The bubble generating device selectively performs a bubble generating process in which bubbles are generated and supplied into the water tub, or a water circulating process in which water from the water tub circulates through the connecting pipe and flows back to the water tub. | 08-16-2012 |
20130145562 | DRUM WASHING MACHINE AND WASHING METHOD THEREOF - A drum washing machine and washing method are provided. The washing machine directly sprays water to laundry inside the drum through a nozzle unit. The method includes passing some water through a detergent container and directly spraying some water to the inside of a drum through a nozzle unit such that a high concentration of detergent bubbles is generated while applying a force to the laundry. The washing machine includes a cabinet, a tub inside the cabinet, a drum inside the tub, a door on the cabinet, a diaphragm, and a nozzle unit installed so interference with the door is avoided and to receive water directly from an external source to spray water inside the drum during a washing cycle and a rinsing cycle. The nozzle unit adjusts water jetting according to a displacement of an actuator installed inside the nozzle unit. | 06-13-2013 |
