AUTOMATIC UNBALANCE ADJUSTMENT
This system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE
1) When the lid is closed, the safety switch contact
is "ON" position.
2) In case that wash loads get uneven during spin,
the outer tub hits the safety switch due to the
serious vibration, and the spin process is
interrupted.
3) In case that P.C.B. ASS'Y gets "OFF" signal from
the safety switch, spin process are stopped and
rinse process is started automatically by P.C.B.
ASS'Y.
4) If the safety switch is operated due to the
unbalance of the tub, the program is stopped and
the alarm is given.
CIRCULATING-WATER COURSE AND LINT FILTER
CIRCULATING-WATER
The washing and rinsing effects have been
improved by adopting the water system in which
water in the tub is circulated in a designed pattern.
When the pulsator rotates during the washing or
rinsing process, the water below the pulsator vanes
creates a water currents as shown in figure.
The water is then discharged from the upper part of
the tub through the water channel.
About 40L/min. water is circulated at the 'high'
water level, standard wash load and standard water
currents.
