Title:
DRUM-TYPE WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2014/199627
Kind Code:
A1
Abstract:
A drum-type washing machine has a configuration such that, by detecting any biaxial displacement of a vibration detector (10) provided in the top front of a washing machine tub (22) while a rotating tub (3) operates at or below the resonance frequency, and correcting the vibrational displacement in accordance with the clothing volume from a clothing volume detector, the amount of unbalance and the unbalance position (in the front-rear direction) of the clothing being washed (18) are precisely identified and a rotational body controlling device (8) is driven under optimized conditions when starting spin-dry. Thus, a drum-type washing machine can be achieved that keeps vibrations generated when the rotational frequency of the rotating tub (3) passes the resonance frequency to a minimum.
