Claim:
1. A laundry machine comprising: a cabinet; a tub provided in the cabinet to hold wash water; a drum arranged in the tub to hold a laundry therein and rotate about a horizontal axis substantially; a gasket provided between the cabinet and the tub; a water supply line to supply the water from an external water source; a spray nozzle provided at the gasket to spray water supplied from the water supply line; a detergent box coupled to the water supply line; a water supply hose coupled to the detergent box to allow the water mixed with detergent to flow from the detergent box into the tub; a drain to drain the tub; a pump to circulate the wash water in the tub; a circulation nozzle provided at the gasket to spray the circulating wash water into the drum; a driving unit installed at a rear side of the tub to rotate the drum; a controller configured to perform a wash drain cycle, wherein the controller causes the drain to discharge the wash water mixed with a washing detergent in the tub out of the cabinet, the controller configured to perform a balancing cycle after the wash drain cycle, wherein the controller causes the driving unit to repeatedly accelerate, maintain, and reduce rotation of the drum to distribute the laundry in the drum, the controller configured to perform an eco rinsing cycle after the balancing cycle, wherein the controller causes the water supply line to supply water from the external water source to the spray nozzle, thereby causes the spray nozzle to spray the water into the drum to remove the remaining washing detergent from the laundry, and causes the driving unit to rotate the drum in a state where at least a portion of laundry is pressed against an inner wall of the drum, the controller configured to perform a spinning cycle after the eco rinsing cycle, wherein the controller causes the driving unit to rotate the drum at a revolutions per minute (RPM) higher than a RPM required to attach the laundry to the drum while causing the drain to drain the tub, shutting off the water supply line to stop spraying the water, and causing the driving unit to accelerate the speed of the drum without reducing the speed of the drum, wherein the controller causes shutting off the water supply line at the same time as accelerating the drum, the controller configured to perform a rinsing cycle after the spinning cycle, wherein the controller causes the driving unit to stop the rotating of the drum and then causes the water supply line to supply water to the detergent box such that a wash water mixed with a rinsing detergent is supplied to the tub through the water supply hose, and the controller causes the pump to circulate the wash water mixed with the rinsing detergent in the tub such that the circulation nozzle sprays the circulating wash water mixed with the rinsing detergent into the drum and causes the driving unit to rotate the drum in a variety of RPMs and a variety of directions, the controller configured to perform a rinse draining cycle after the rinsing cycle, wherein the controller causes the driving unit to stop the rotating of the drum and then causes the drain to discharge the wash water mixed with the rinsing detergent in the tub out of the cabinet, the controller configured to perform another eco rinsing cycle after the draining cycle, wherein the controller causes the water supply line to supply water from the external water source to the spray nozzle, thereby causes the spray nozzle to spray the water into the drum to remove the remaining rinsing detergent from the laundry, and causes the driving unit to rotate the drum in a state where at least a portion of laundry is pressed against an inner wall of the drum.
