WATER LEVEL SWITCH
Water pressure of air room which is at the side of outer-tub is transmitted to the air room in the water leVE
switch through air-tube. Diaphragm moves up and down by the transmitted pressure to move the core.
Movement of core transforms the inductance of coil by Henly's Law.
The generative frequency (Hertz) is obtained by this transformation of the coil inductance in the LC genes
tive circuit.
GEAR MECHANISM ASS'Y
The proper water currents is made by the rotation of pulsator at a low speed (about 145 r.p.m) to prever
the damage to the small sized clothes.
