2. FEATURE AND TECHNICAL EXPLANATION FEATURE AND TECHNICAL EXPLANATION FEATURE OF THE WASHING MACHINE 1) The first air bubble washing system in the world. 2) Quiet washing through the innovational low-noise design. 3) The wash effectiveness in much more enhanced because of the air bubble washing system. 4) The laundry detergent dissolves well in water because of the air bubble washing system.
Page 5: Pulsator System, Automatic Draining Time Adjustment
PULSATOR SYSTEM When the new shaped pulsator is rotated C.W or C.C.W at a high speed, it makes the ‘heart-shaped’ water currents as shown below. WATER CURRENTS A Water is pushed up near the tub Rotate wall by rotation on the pulsator. B Water is pulled down in the middle of the tub by rotation of the pulsator.
Page 6: Softener Dispenser
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 poured into softener inlet. 2) Softener moves from (A) to (B) by centrifugal force during intermittent spin process. 3) Softener flows from (B) to (C) during rinse process next to intermittent spin.
Page 7: Automatic Unbalance Adjustment, Circulating-water Course And Lint Filter
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. Contact of safety switch Lid closing 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.
