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℃.

Note : Some

roducts do not offer this o

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
