Dehydrating operation controlling method for drum type washing machine, by accelerating motor to predetermined control starting speed during pre-acceleration step, and further accelerating motor to target speed during main acceleration step

摘要

#CMT# #/CMT# A motor that drives a drum of a washing machine is accelerated to a predetermined control starting speed during a pre-acceleration step. The motor is accelerated from the control starting speed to a target speed along a linear locus having a preset acceleration slope during a main acceleration step. #CMT#USE : #/CMT# For drum type washing machine. #CMT#ADVANTAGE : #/CMT# Motor speed is controlled to optimum speed during spinning. Prevents occurrence of sharp speed increases of motor during acceleration of motor. Reduces deviation of center of gravity of load of laundry during spinning and pre-spinning operating periods. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure is a flowchart of the dehydrating operation controlling method.
