2-4. REED SWITCH FOR APPLIANCE SAFETY(WF-402, T652A, T452A)
2-5. BALL PRESSURE SENSOR
Interrupt system of reed S/W is differed from safety S/W incorporated in the
previous models. Reed S/W is located on PWB ASM and operated with a magnetic
incorporated inside of Lid-B systemically. If Lid is the closed position, the magnetic
operates the contact of Lid S/W. In this case, the machine can do the normal
operation because the current pass through the contacts. On the other hand, the
contacts is open after Lid is the open position, the machine is stoped because the
magnetic is far from the Reed S/W. So do not place any electric appliance with a
charging battery, magnetically-driven appliance and magnetic body on the washer.
It makes misoperation of washing machine process.
To detect unbalance, the electronic sesing system is used which is differ from safety
S/W incoporated in the previous models. In the abnormal operation like unbalance
of clothes during spinning, etc, the ball inside of sensor is moved. In this case the
inductance of sensor is differ from the initial condition. So micom sense the
unbalance condition by ball movement. Ball pressure sensing system is higher
safety performance, sesing vertical movements and no deformation and noise by
over of safety S/W.
