Braking refers to the braking in the dehydration operation. It has two situations: one is the braking at the end of the dehydration; the other is the braking when the upper cover is opened during the dehydration operation.
(1) Braking principle at the end of dehydration. At the end of dehydration, the motor and clutch electromagnet are de-energized, the moving iron core is restored, and the moving iron core blocks the rotating brake band, causing sliding resistance between the brake band and the spring sleeve. The rotation of the spring sleeve is slower than the inner hub (2), the torsion spring (middle) is tightened, and the power is transmitted to the brake disc via the inner hub (1), so that the dehydration barrel stops rotating.
(2) The braking principle when the upper cover is opened. Because the washing machine is equipped with a safety switch, if the upper cover is opened during dehydration, the safety switch will act to cut off the power of the clutch electromagnet and the motor. After the electromagnet is de-energized, The moving iron core is restored to generate sliding resistance between the brake band and the spring sleeve, so that the torsion spring (middle) is tightened, the power inner hub (1) is transmitted to the brake disc, the brake starts to work, and the dehydration barrel stops.
