A laundry treatment apparatus, comprising: a cabinet with a laundry feeding hole formed therein; a tub provided within the cabinet for holding washing water; a drum, rotatably installed around a rotation axis which is forward inclined within the tub, for holding laundry; a driving unit to rotate the drum; a balancer disposed in the drum and having an internal space therein, wherein water is selectively introduced into the internal space of the balancer when the drum is rotated; a centrifugal channel device disposed on a backside of the drum, rotated along with the drum, and having an opening portion formed toward a back direction so that water is supplied to the opening portion and guided into the internal space of the balancer; and a nozzle disposed at a back of the drum, spaced apart from the drum, to spray water toward the opening portion; wherein the centrifugal channel device includes: - a circumferential channel through which supplied water moves in a circumferential direction of the drum by forming a space in which the supplied water is contained in a centrifugal direction, wherein the circumferential channel is disposed in a direction opposite the centrifugal direction with respect to an inflow hole formed at a point at which water is introduced from the centrifugal channel device to the balancer; and - a centrifugal channel extended from the circumferential channel in the centrifugal direction; characterized in that the centrifugal channel device further includes: - a front channel extended from the centrifugal channel to the inflow hole; and - a channel partition extended in the centrifugal direction from a center of the inflow hole and dividing the inflow hole, the front channel, the centrifugal channel, and the circumferential channel. a cabinet with a laundry feeding hole formed therein; a tub provided within the cabinet for holding washing water; a drum, rotatably installed around a rotation axis which is forward inclined within the tub, for holding laundry; a driving unit to rotate the drum; a balancer disposed in the drum and having an internal space therein, wherein water is selectively introduced into the internal space of the balancer when the drum is rotated; a centrifugal channel device disposed on a backside of the drum, rotated along with the drum, and having an opening portion formed toward a back direction so that water is supplied to the opening portion and guided into the internal space of the balancer; and a nozzle disposed at a back of the drum, spaced apart from the drum, to spray water toward the opening portion; - a circumferential channel through which supplied water moves in a circumferential direction of the drum by forming a space in which the supplied water is contained in a centrifugal direction, wherein the circumferential channel is disposed in a direction opposite the centrifugal direction with respect to an inflow hole formed at a point at which water is introduced from the centrifugal channel device to the balancer; and - a centrifugal channel extended from the circumferential channel in the centrifugal direction; - a front channel extended from the centrifugal channel to the inflow hole; and - a channel partition extended in the centrifugal direction from a center of the inflow hole and dividing the inflow hole, the front channel, the centrifugal channel, and the circumferential channel.
