channel
Pulsator
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 auto-
matically 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
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 pul-
sator 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 40 L/min. water is circulated at the ‘high’
water level, standard wash load and standard
water currents.
12 EXPLANATION
FUNCTIONAL PRINCIPLE
1
The micom can remember the time from the begining of drain to reset point when the pressure switch reaches to
“OFF” point
2
In case of continuous draining, residual drain time is determined by micom.
Draining time as a whole = D + 90
Residual drain time.
The time remembered by micom.
Asymmetrically designed pulsator
makes the cyclone water fow, which get
rid of the washing dead zone to
increase the washing effect and reduce
the entanglement of laundry.
Draining
Good draining The washer begins spin process after drainage.

Pulsator System
When the pulsator is rotated C.W or C.C.W at a high speed, it makes the cyclone water flow from the asymmetrically
designed pulsator as shown below.
Automatic Drainning time Adjustment
This system adjusts the draining time automatically according to the draining condition.
