1)Computer sequencer

It adopts pouring seal with polyurethane on the surface. The light-emitting diode 

is sealed with insulation bushing to avoid humidity. To avoid splashing, the surface 

of computer plate and box and the operation components of the control panel seat 

are coated with control panel film.

2)Structure of the top lid

The top lid adopts transparent view window structure. If the top lid is closed, you 

can observe the running of the washing machine through the transparent lid.

Please pay attention in installation of the hangers that the spring of the hanger 

at the motor side (two) is different from those installed on the other hangers (two).

3)Power transmission system

     

During  washing, the  rotation of Motor 1 is transferred  to Follower 5 from Drive Wheel 2 through 

Belt 3. Meanwhile, Ratchet 7 will be braked by Pawl 8 through the action force of the spring, and

the  movement  will  be  transferred  to Center Gear 9, and  then  be retarded and  transferred  to 

Tie-rod 10 through a planetary gear mechanism consisting of Center Gear 9, Planet Gear 10 and

Spin Shaft 4 (inner gear), then Tie-rod 10 is connected to Pulsator 12 via a spline shaft.Therefore,

Pulsator 12 will move along with the clockwise and counterclockwise  rotation of the Motor 1.

During  spinning, the rotation of  Motor 1 is  transferred to Follower 5 from Drive Wheel 2 through

Belt 3. Meanwhile, Pawl 8 will leave Ratchet 7 by the action of the puller. Clutch Reed 6is twisted

tightly on  the down part of Spin Shaft 4. The Spin tub 13 is connected to Spin shaft 4 with flange. 

The  movement  of  Motor 1 will be retarded  by V-belt, and  then transferred  to Spin shaft  4 and 

make the Spin tub 13 to spin.
