More economical by Intelligent Wash System
Intelligent Wash System detects the amount of load and water temperature, and
then determines the optimum water level and washing time to minimize energy
and water consumption.
then determines the optimum water level and washing time to minimize energy
and water consumption.
Low noise speed control system
By sensing the amount of load and balance, it evenly distributes load to minimize
the spinning noise level.

2-2.DETERMINE WASHING TIME BY FUZZY LOGIC
To get the best washing performance optimal time is determined by sensing of water temperature,
selected washing temperature and laundry amount.
2-3.WATER LEVEL CONTROL
● This model adopts a pressure sensor which can sense the water level in the tub.
● Water supply is stopped when the water level to the preset level, then washing program proceeds.
● Spinning does not proceed until the water in the tub reduces to a certain level.
