AUTOMATIC POWER OFF
P.C.B. ASS'Y sends a signal to the solenoid in the power switch 10 minutes later after complete washing.
Then the solenoid pull the locking lever which had lock the push button. Therefore the power is turned off automatically.
RESIDUAL TIME DISPLAY
When the START/HOLD button is pressed, the residual time (min.) is displayed on the time indicator, and it will be counted
down according to the process.
When operation is finished, the TIME INDICATOR will light up
.
DRAIN MOTOR
STRUCTURE
FUNCTIONAL PRINCIPLE
1. When the DRAIN MOTOR connected to the power source (AC 220V), the DRAIN MOTOR rotates with 900 r.p.m and
revolves the pulley by gear assembly for reducing.
2. When the pulley is rotated, the pulley winds the wire to open the drain valve.
3. Therefore, rotation of pulley is changed to the linear moving of wire.
4. The wire pulls the brake lever of Gear Mechanism Ass'y within 5 seconds.
5. After the wire pulled, gear assembly is separated from motor and condition of pulling is held by operation of the lever.
6. When the power is turned off, the drain valve is closed because the wire returns to original position.
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 level 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 generative circuit.
