AUTOMATIC WATER SUPPLY SYSTEM ON BLANKET WASH

The water level would be lowered because the blanket absorbs water at the beginning of washing.

Therefore, after 30 seconds, the operation is interrupted to check the water level, and then the water is supplied again until it is reached at the selected level.

WATER FLOW ON STRONG WASH

It washes cleanly the heavily stained clothes such as working-clothes, climbing-clothes and blue-jean by using this strong water currents as shown below.

SOFTENER DISPENSER

This is the device to dispense the softener automatically by centrifugal force.

This is installed inside the auto-balancer.

FUNCTIONAL PRINCIPLE

1.Softener stays in room (A) when pour the softener to softener inlet.

2.Softener move (A) to (B) by centrifugal force during intermediate spin process.

3.Softener flow (B) to (C) during rinse process next of intermediate spin.

4.Softener move (C) to (D) by centrifugal force during second intermediate spin.

And after finish spin process, softener drop between tub and outer tub ass'y from softener outlet.

AUTOMATIC UNBALANCE ADJUSTMENT

This system is to prevent abnormal vibration during intermittent spin and spin process.

FUNCTIONAL PRINCIPLE

1.When the lid is closed, the safety switch contact is "ON" position.

2.In case that wash loads get uneven during spin, the outer tub hits the safety switch due to the serious vibration, and the spin process is interrupted.

3.In case that P.C.B. ASS'Y gets "OFF" signal from the safety switch, spin process are stopped and rinse process is started automatically by P.C.B. ASS'Y.

4.If the safety switch is operated due to the unbalance of the tub, the program is stopped and the alarm is given.

CIRCULATING-WATER COURSE AND LINT FILTER

CIRCULATING-WATER

The washing and rinsing effects have been improved by adopting the water system in which water in the tub is circulated in a designed pattern.

When the pulsator rotates during the washing or rinsing process, the water below the pulsator vanes creates a water currents as shown in figure.

The water is then discharged from the upper part of the tub through the water channel.

About 40L/min. water is circulated at the 'high' water level, standard wash load and standard water currents.

LINT FILTER

Much lint may be obtained according to the kind of clothes

to be washed and some of the lint may also sticks to the clothes. To minimize this possibility, a lint filter is provided on the upper part of the tub to filter the wash water as it is discharged from the water channel. It is good to use the lint filter during washing.

HOW TO CLEAN THE LINT FILTER

1.Pull the filter frame upward.

2.Turn the lint filter inside out, and wash the lint off with water.

3.Return the filter as it was, and fix the filter frame to the slot.

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 .

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.

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 prevent the damage to the small sized clothes.

SAFETY DEVICE FOR MOTOR

In case of occurring disorder of motor caused by extreme-high voltage, over-heating, overload, safety devices (Thermal Protector) of motor can be operated and cut off the power sources automatically.

At this case, motor does not run.

However, motor can be operated normally again about 1 hour later.

PRINCIPLE OF INTAKE & OUTLET OF THE AIR

INTAKE : ARMATURE moves to the upper side, and BELLOWS inhales the air. At same time, PROTECTOR B is open and A is close.

OUTLET: ARMATURE moves to the down side, and BELLOWS exhaust the air. At same time, PROTECTOR B is close and A is open.

FUNCTIONAL PRINCIPLE OF TRANS & MAGNET

A.C electric power's phase changes to 60 cycle/sec.

Trans core's magnetic pole is changed by changing of A.C electric power's phase.

The core repeat push and pull (3600 times/min) the armature magnet.
