Abstract:
1. A laundry machine comprising: a cabinet; a tub within the cabinet; a drum rotatably arranged in the tub, wherein the drum includes a plurality of holes to allow water to pass therethrough; a first nozzle to introduce the water to the drum; a water supply line to supply the water from a water supply source to the first nozzle; a detergent box coupled to the water supply line; a water supply hose coupled to the detergent box to allow the water mixed with at least one content of the detergent box to flow from the detergent box to the tub; a drain to drain the tub; a driving unit to rotate the drum; a second nozzle; a pump; a controller configured to perform a balancing process, wherein the controller causes the driving unit to rotate the drum such that laundry attaches to the drum and becomes balanced within the drum, the controller configured to perform a first rinsing process, wherein the controller causes the water supply line to supply the water to the first nozzle, thereby causing the first nozzle to introduce the water to the drum in a form of a spray, while the drum is rotated such that the laundry remains attached to the drum and rotates with the drum, the controller configured to perform a spinning process after performing the first rinsing process, wherein the controller causes the driving unit to rotate the drum at a revolutions per minute (RPM) higher than a RPM of the first rinsing process while causing the drain to drain the tub, the controller preventing the water supply line from supplying water to the first nozzle, the controller configured to perform a water supplying process after performing the spinning, the controller causes the water supply line to supply the water to the detergent box to be mixed with the at least one content of the detergent box, thereby the water mixed with the at least one content of the detergent box to flow from the detergent box to the tub through the water supply hose, while causing the driving unit to rotate the drum at a RPM higher than or equal to a RPM at which the laundry is attached to the drum and rotates with the drum and lower than the RPM of the first rinsing process, the controller configured to perform a water-falling rinsing process after performing the water supplying process, wherein the controller causes the pump to pump the water mixed with the at least one content of the detergent box from the tub to the second nozzle, thereby causing the second nozzle to introduce the water mixed with the at least one content of the detergent to the drum in the form of the spray, while causing the driving unit to rotate the drum at a RPM higher than or equal to the RPM at which the laundry is attached to the drum and rotates with the drum, the controller configured to perform a draining process after performing the water-falling rinsing process, wherein the controller causes the drain to drain the tub while causing the driving unit to rotate the drum at a RPM higher than equal to the RPM at which the laundry is attached to the drum and rotates with the drum, the controller configured to perform a second rinsing process after performing the draining process, the controller causes the water supply line to supply the water to the first nozzle, thereby causing the first nozzle to introduce the water to the drum in a form of a spray, while causing the driving unit to rotate the drum at a RPM higher than the RPM of the draining process such that the laundry is attached to the drum and rotates with the drum, wherein between the first rinsing process, the spinning process, the water supplying process, the water-falling rinsing process, the draining process, and the second rinsing process, the controller configured to cause the driving unit to rotates the drum continuously.
