1. Replacing the clutch of a fully automatic washing machine is troublesome. First, unscrew the screws that fix the surface frame, and remove the four screws that fix the outer barrel ring and remove the outer barrel ring.

2. Unscrew the impeller screw and take out the impeller, then use a special sleeve to unscrew the large nut that fixes the inner barrel (the inner barrel of Q818 and Q828 models is fixed with four M6 bolts) and remove the clutch of the fully automatic washing machine Take out the inner barrel.

3. Lay a piece of soft cloth on the ground, turn the washing machine sideways, use a sleeve to unscrew the two bolts that fix the protective frame on the clutch of the automatic washing machine, and remove the protective frame.

4. Use a sleeve to unscrew the four bolts that fix the clutch, take off the belt, and finally take out the automatic washing machine clutch and replace it with a new clutch. Just follow the original steps to assemble the fully automatic washing machine clutch.

5. The degree of dirtiness of clothing is judged by the transparency of water. Add an infrared photoelectric sensor to the drain outlet of the laundry barrel to allow infrared light to pass through the water and enter the receiving tube on the other side. If the transparency of the water is low, the light energy obtained by the receiving tube is small, indicating that the clothes are dirty. A piezoelectric sensor is used during dehydration. When the dehydration barrel is highly rotated, the water sprayed from the dehydration barrel acts on the piezoelectric sensor. According to this pressure change, the dehydration operation is automatically stopped.

6. When we inject a certain amount of water into the washing bucket, we make the motor run at low speed, and then quickly cut off the power after it is stable. The washing bucket drives the motor to continue to rotate under the action of inertia. At this time, the motor winding generates a counter electromotive force, which affects the After half-wave rectification, amplification and shaping, a rectangular pulse series is obtained. By analyzing the pulse number and pulse width, the clothing quality and quantity can be obtained.
