8) 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
over 2 times the function is going at default condition ( high water level ), if 1 time 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 Rinse water level
Cotton Coloureds
High Default Default Default
Middle Default-20 min Default-10min 23.80KHZ
Low Default-30 min Default-15min 24.10KHZ
ĆAfter sensing weight, above hours is decreased from above default hours
9) Bubble - detecting function
At the each condition of washing&dehydrating , rinse&dehydrating , hydrating, bubble -detecting function
works, this function works 5times normally, if the function detects bubbles at 6 times , the bubble-detecting function
stops and go on to the next process.
● The bubble-detecting function during washing & dehydrating to rinse & dehydrating
after 2 times instant dehydrating and before main dehydrating, if the water level is under 24.50KHZ,
Bubble
→ Detecting function thinks there are bubbles and add the bubbles-removing rinse, needing
hours are above hours and 8 Min 40 sec.
→ The bubble-detecting function during single hydrating process
after 2 times instant dehydrating and before main dehydrating , if the water level is 24.50KHZ below or
during main dehydrating, water level data is 24.50KHZ below Bubble-detecting function thinks there are
bubbles and add the bubbles-removing rinse 1 times, needing hours are above hours and 5 min 50 sec.

10) Unbalance detecting & laundry balance positioning system
ķ Just before the hydrating process and just after reversal rotation for balancing laundry position, this
function is carried out
ĸThe initial 6 sec is the period of reversal rotation for balancing laundry position , Drum rotates 50rpm
for initial 6 sec
Ĺ Next 12 sec, the rotation increases the speed from 50 rpm to 95 rpm slowly
ĺDuring the next 8 sec, drum rotates at the speed of 95 rpm, the sensor decides the degree of laundry
unbalance with TACHO data which is attached to motor
Ļ If the degree of unbalanced laundry is over 6 times to default value, laundry balancing system carryies
out feed back process 3 times.

11) 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 rectangular wave generating circuit, the waves reaches MICOM and micom controls
r.p.m with the pulse, count and cycle inputted by program.
