2. Safety Devices

※

We adapt 5 safety devices for users to use this wash machine safely.

1) Balancing device (ASSY-Main PCB)

→

When the lauandry is out of balance, to prevent the noises and vibrations, the unbalance

detecting sensor helps the laundry laid even and continue the dehydating process.

2) Anti-over water supply device

→

Because water supply value is broken, once water is supplied to the 2/3 level of the door, the

water supplied is drained automatically, Over -flow error (E3) is diplayed on the panel

3) Temperature-regulating device(thermistor)

→

To prevent over-heating over the temperature setted up, THERMISTOR senses the temperature of

the machine continuously and helps the wash machine to work at the temperature given by users.

4) Overheating- controlling system

→

Under the circumstances of THERMISTOR inferiority or abnormal condition, if wash-heater is

overheated, automatically, assy -thermal fuse cuts off the power supply to protect the machine to

keep it safe.

5) Delicate clothing safeguard function(ASSY-Main PCB)

→

To protect the clothings which is weak to high temperature, the wash machine senses the

temperature inside the washing tub. if the temperature rises over 50℃wool washing course and

Delicate washing course display abnormal water temperature on the panel , after draining the

water.

5. Main function

10) Fuzzy washing function ( weight-sensing)

☞

After finishing initial water supply, when the fall of the water level needs supplementary water supply,

Sensing function perceives the weight with the supplementary water supply numbers and starts to work.

Under the course of Cotton, or Coloureds, if the supplementary water supply numbers become 3 - 4 times the

function is going at default condition ( high water level ), if 1-2 below that is going at middle level, if 0 below

low water level, heating hours and rinse hours depend on the above data.

ECO PRE mode is selected, the process going on at default condition.

Washing hours

12) Unbalance detecting & laundry balance positioning system

①

Just before the hydrating process and just after reversal rotation for balancing laundry position, this function is

carried out

②

The initial 6 sec is the period of reversal rotation for balancing laundry position , Drum rotates 50rpm for

initial 6 sec

③

Next 10 sec, the rotation increases the speed from 50 rpm to 90 rpm slowly

④

During the next 18 sec, drum rotates at the speed of 90 rpm, the sensor decides the degree of laundry

unbalance with TACHO data which is attached to motor

⑤

If the degree of unbalanced laundry is over 6 times to default value, laundry balancing system carries out

feed back process 6 times

13) R.P.M control

The rotating motor enables the magnetics( i.e generator) to generate magnetic flux in proportion to r.p.m,

magnetic flux induced by coil sensor in the opposite side produces the wave like the figure below to dΦ/dt and

via rectangual wave generating citcuit, the waves reaches MICOM and micom controls r.p.m with the pulse,

count and cycle inputted by program.
