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.
