Title:
DRUM TYPE WASHING MACHINE
Document Type and Number:
Japanese Patent JP2019092708
Kind Code:
A
Abstract:
To provide a drum type washing machine which can shorten washing time by performing a dewatering step quickly even when there is uneven distribution of laundry in a washing tub.SOLUTION: A washing machine includes: a plurality of pieces of baffles which are hollow balancers; a water supply valve for pouring water to the baffles; a proximity sensor in which one signal generates every time a drum rotates once; a triaxial acceleration sensor for detecting the vibration of an outer tub; and a central control part which is detection means for detecting the amplitude of the outer tub and the eccentric position of the drum. In the case where an eccentric amount in the drum reaches a specified value or higher, by pouring water to the baffles, the eccentric amount is reduced. In a dewatering operation, a pouring water threshold value at which pouring water starts and an acceleration threshold value at which acceleration starts after pouring water are changed by providing relevance between the vertical amplitude, the left-to-right amplitude and the frontward/backward amplitude.SELECTED DRAWING: Figure 13
