Title:
DRUM WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/100695
Kind Code:
A1
Abstract:
Provided by the present invention is a drum washing machine which is capable of reliably reducing an imbalance in a washing drum when removing water even when laundry items within the washing drum are offset, removing water rapidly so as to shorten washing time. The washing machine (1) of the present invention is characterized in: a feeding port sealing element (PK), and a washing main body (1a) which is connected to an external drum (3) in order to seal water and which serves as a frame; a proximity switch (14) which serves as as a location detection device for a hollow balancer within a drum, wherein a drum (2) within the external drum (3) generates a signal once per each rotation; a single acceleration sensor (12), which is used for detecting the vibration of the external drum; a central control part (31) which serves as an eccentric position detection unit, detecting eccentric positions (N) in the forward and backward direction, upward and downward direction and left and right direction of the drum (2); the washing machine (1) considers a phase difference generated by the difference between the eccentric positions (N) of the drum (2) in the forward and backward direction so as to calculate the eccentric positions (N) in the upward and downward direction and left and right direction.
