The most obvious feature of this machine is that during washing, the
pulsator and inner tub rotate to opposite direction, and thus make double
washing effect. It is realized as following three points:
The retarder of this washing machine is different from former ones. It
adopts dual ratchet and dual pawl structure. The brake arm has two
action steps: the first step is applicable for washing mode: the brake belt
is opened to make the brake wheel free. But the pawl does not leave the
ratchet. The clutch spring keeps loose; the second step is applicable for
spinning. The pawl leaves the ratchet. The clutch spring integrates the
input shaft and clutch shaft and performs the spinning with the drive of
motor.
There are two strokes of the drain motor: the first stroke is used in
washing. The second stroke is used in spinning.
Comparing with the former drain valve, this machine adopts dual
valve pipe as the substitution of the former single valve pipe, which can
guarantee that during washing the pulsator and the inner tub rotate to
opposite directions, and thus make hand-wash type washing. In spinning,
