GEAR EMCHANISM ASS'Y
The proper water currents is made by the rotation of pulsator at a low speed (about 140 r.p.m) to prevent
the damage to the small sized clothes.

PRINCIPLE OF INTAKE & OUTLET OF THE AIR
INTAKE : ARMATURE moves up, and BELLOWS inhales the air. At the same time, protector B is open
and A is close.
OUTLET : ARMATURE moves down, and BELLOWS exhausts the air. At the same time, protector B is
close and A is opend.
FUNCTIONAL PRINCIPLE OF TRANS & MAGNET
The phase of A.C electric power changes to 60 cycle/second.
The magnetic pole of trans core is changed by the change of the phase of A.C electric power.
The core repeats push and pull (3600 times/min.) of the at mature magnet.
