Power supply for balancer of a laundry treatment apparatus

Abstract

A laundry treatment apparatus (100) including a cabinet (1) forming an appearance of the apparatus, a drum (3) having a laundry space therein to accommodate laundry, a rotating shaft (45) for rotatably supporting the drum (3) in the cabinet (1), a balancer (51, 53) including a housing (55) fixed to the drum (3), an accommodation space (553) defined in the housing (55), a balancing unit (57) movably provided in the accommodation space (553), and a housing power line (555) provided in the accommodation space (553) to supply the balancing unit (57) with electric power, a shaft through-hole (451) formed through the rotating shaft (45), a first power supply unit (61), fixed to the rotating shaft (45), including a connection line connected to the housing power line (555) through the shaft through-hole (451), and a second power supply unit (63) rotatably fixed to the first power supply unit (61) to connect the connection line to a power source.

Description

technical field [0001] The present disclosure relates to a laundry treating device. Background technique [0002] A conventional laundry treating apparatus includes: a cabinet defining the appearance of the apparatus; a tub installed in the cabinet; a drum rotatably installed in the tub to wash laundry; and a motor having a motor coupled to the drum while wearing Pass the rotating shaft of the bucket to make the drum rotate. [0003] The drum may rotate without depending on the position of laundry arranged therein to maintain dynamic balance (dynamic balance). [0004] "Dynamic balance" refers to a state in which the centrifugal force of the rotating body or the moment caused by the centrifugal force becomes zero with respect to the rotation axis during the rotation of the rotating body. In the case of a rigid body, dynamic equilibrium is maintained when the mass of the rigid body is evenly distributed about the axis of rotation. [0005] Therefore, the dynamic balance of...

Problems solved by technology

[0011] Although the above-mentioned unbalance control is useful under vibration conditions in a steady state where the amplitude of the vibration of the drum falls within a predetermined range, the momentary vibration experienced by the drum before the vibration of the drum reaches a steady state Satisfactory results cannot be obtained under

[0012] Furthermore, it is difficult for conventional balancing units to immediately resolve (proactively resolve) an unbalanced condition when it occurs
