Patent number: 11739457Abstract: The present disclosure relates to a laundry treatment machine and a method for controlling the same. An increased amount of wash water during dewatering is introduced into a pump by decreasing the speed of a pump motor provided in the pump and increasing it again based on changes in the speed of the main motor during dewatering, and the wash water introduced while the speed of the pump motor is increasing is drained. Thus, the amount of noise generated during drainage may be reduced, drainage performance may be improved, and drainage time may be shortened.Type: GrantFiled: July 5, 2019Date of Patent: August 29, 2023Assignee: LG ELECTRONICS INC.Inventors: Junsung Kim, Kiwook Lee, Jongseok Jung
