1. Technical point of some key parts
1-1. Spin Timer
Function
Structure and Principle of Activation
1-2. Drain Pump
The Spin Timer is the switch providing to the Spin Motor(Drain Pump Motor) during the set
spin dry time, and is a spring-type time switch comes on upon turning and those contact
points comes off after the set time.
1) The main shaft turns due to the unwinding force when the spin timer is turned and the
spring timer wound, with that force being delivered through each gear and the spring slowly
unwinding at a speed finally controlled by the angle assembly.
2) The contact point turns ON and the assembly angle is set in motion, which is in the CAM
groove in the OFF state, comes off the groove when the MAIN SHAFT is turned to wind the
spring. The contact point turns OFF, return to CAM groove when the spring unwind
completely.
Drain pump is designed to drain the water in selecting drain, spinning and water level being
high. Draining capacity is 18l/min. when the drain hose is 1.5m height.
a) Drain : The Drain Pump is turned on when the Drain Selector Knob is set to "DRAIN" while
the Wash Timer is ON. In this case the Drain Select Knob open the Drain Valve and drain
time can be controlled by Wash Timer.
b) Spinning : The POWER is provided to Spin Motor and the Drain Pump Motor by Spin
Timer so that the water is drained simultaneously with spinning.

c) water level being high : The Drain Pump is turned on when the water level reaches
approx. 9.5cm above level High. It is then turned off when the water level returns to level
High. It is operated automatically so that the water level maintains between level High and
approx. 9.5cm above level High.

overloading so that the temperature of motor reaches to about 135℃the thermal protector
attached to the motor shuts off the motor automatically. In this case the motor does not
operate, and is activated only after about an hour when motor temperature drops to about
85℃.

The Spin Dryer is an apparatus which eliminates the water from laundry through centrifugal
separation generated by rapid revolution(approximately 1,600 revolution per minute for
frequency of 60Hz). Accordingly, there are a Door Switch to cut off the power going into the
Spin Motor when Door Spin *0 is operated and a brake system to stop the rotating Spin
Dryer.
Drain Pump Motor
Drain Pump Motor is a shaded pole motor with a pump impeller, rotate about 2650 rpm to
operate the pump fan to drain.
As a mechanical switch, Pressure Switch turns ON by air pressure when the water level
reaches approx. 9.5cm above level High so that the Power is provided to the Drain Pump
which designed to drain the water to prevent overflow out the tub.

Door Switch
When the Door Spin *0 is operated during spin drying the Lever of the Door Switch which
sites the Door Spin *0 falls off the contact, and cuts off the Power going into the Spin Motor.
Brake System
When the Door Spin *0 is opened, the Plate Control Wire which sites separately atop and
Door Spin *0 drop down and loosens the Link Wire and Link Brake. And when the Brake
Band touches the Drum coupling Assembly and stops the Spin Dryer as it is pulled by the
spring in the Brake Fix Assembly.

Brake Band Gap Control Method
The Band Brake works best when the gap between it and the Drum Coupling is about 2mm
when the Door Spin *0 is closed. The Spin Dryer stops slowly if the gap is larger in which
case the screw of the Wire Guide may be loosened and adjusted upwards. If the gap
between the two is too narrow, the Spin Dryer revolution is affected and the Wire Guide may
be adjusted downward to maintain the Brake Band gap adequately.
The initial deceleration following the activation of the Wash Motor takes place through the
Motor Pulley and the Agitator Pulley, and the secondary deceleration is done by the gears in
the Gear Housing which also increases their revolution strength. This revolution speed and
strength is delivered to the Agitator, which is then able to cause water current that is strong
yet soft so that wash loads are not damaged.
The wrinkled rubber device on the
bottom of the spindryer is called
Spin Bellows assembly. It has a
waterseal and a oilless metal
inside to prevent leakage and so
that the Spin Dryer may work
