Method of controlling washing machine

摘要

A method of controlling a washing machine is provided. The rotation and rotation driving time of a inner tub having an auto balancer are controlled based on preset values considering sections during which a horizontal unbalancing phenomenon and a vertical unbalancing phenomenon occur. Accordingly, abnormal vibrations and resultant damage or deformation of the washing machine may be prevented. Further, electricity may be saved.

主权项

1. A method of controlling a washing machine having an auto balancer that compensates for an unbalancing phenomenon occurring when an inner tub rotates, wherein the inner tub is rotably disposed vertically inside an outer tub at a top side of which an opening for entering and exiting laundry is formed, the method comprising:
a step of setting a first lower RPM value and a first higher RPM value, wherein the inner tub is biased in a left and right direction of the inner tub and causes a first unbalancing rotation if the inner tub rotates constantly at a first RPM between the first lower RPM value and the first higher RPM value; and a step of controlling the inner tub to be rotated constantly at at least one predetermined RPM lower than the first lower RPM value for a predetermined time period, and then be accelerated from the predetermined RPM lower than the first lower RPM value to a second RPM higher than the first higher RPM value such that the inner tub is not rotated constantly at the first RPM, and then controlling the inner tub to be rotated constantly at the second RPM for a predetermined time period.
