How to repair the fault of the automatic washing machine water inlet solenoid valve

Nowadays, if people want to buy a washing machine, a fully automatic washing machine is definitely the first choice. Then when it comes to fully automatic washing machines, in the daily use process, if the automatic washing machine fails, how should we carry out maintenance? Is there any skill to refer to?

How to repair the fault of the automatic washing machine water inlet solenoid valve

Automatic washing machine water inlet solenoid valve troubleshooting First step: Inlet water solenoid valve is mainly composed of iron core, rubber valve, coil, metal filter, water flow pad, valve seat, magnet frame, spring and so on. The filter screen acts to block the impurities in the water from entering the water inlet valve. The water flow pad has 3-5 small holes on the top of the water flow pad, which mainly serves to limit the amount of water entering. The coil, the magnet frame and the armature constitute an electromagnet.

Fully automatic washing machine water inlet solenoid valve troubleshooting second step: When the inlet valve is not energized, the iron core is pressed down on the rubber valve under the spring force of the spring, sealing the center hole of the rubber valve, if this will The water source is connected, the water advanced person A cavity, and then enters the B cavity through the small hole in the rubber valve. At this time, the A and B chambers are filled with water, and a certain water pressure is applied to the rubber valve. At this time, the rubber valve seals the passage from the A chamber to the C chamber, and the washing machine does not enter the water.

The automatic washing machine water inlet solenoid valve troubleshooting The third step: the water inlet solenoid valve is energized when the washing machine enters the water, and the water flow acts to cool the inlet valve when working. If the inlet valve is energized for a long time, but no water enters, the inlet valve coil is liable to burn out due to excessive temperature. Therefore, it is recommended that the user unplug the power plug when not using the washing machine or when it encounters water stoppage.

What is the principle of automatic washing machine?

What is a fully automatic washing machine? The semi-automatic washing machine needs to manually put the clothes into the dewatering bucket for dehydration. It is fully automatic from washing to dehydration. The principle of washing is to rotate the water and the clothes to rotate through the inner wall of the washing tub by the motor. Point friction and water flow to squeeze the clothes to achieve the purpose of washing, similar to the principle of the washboard, dehydration is high-speed rotation, dehydration by centrifugal force.

Let's take a look at what is the principle of this? The washing process of the washing machine is mainly to remove the dirt and the like by mechanical action and the wetting and dispersing of the detergent, and the dirt is pulled into the water to achieve the purpose of washing. First, the washing liquid filled between the pulsator blades is smashed toward the wall of the barrel by the centrifugal force and rises along the wall of the barrel. At the center of the pulsator, a low pressure zone is formed by the liquid being pulled out, which in turn causes the washing liquid to flow back to the vicinity of the pulsator. Thus, a vortex centered on the pulsator axis is formed in the vicinity of the pulsator.

Is this type of washing machine good? When the electromagnetic coil is energized, the moving iron core moves up under the action of the magnetic force, leaving the diaphragm and opening the center hole of the diaphragm, so that the water above the diaphragm flows into the laundry through the center hole. Inside the bucket. Since the flow capacity of the central small hole is greater than the flow capacity of the small holes on both sides of the diaphragm, the pressure above the diaphragm is rapidly reduced, the diaphragm will move up under the action of the pressure difference, the closed door is opened, and the water flow is conducted. The water level switch is actually a pressure switch. The inlet of the gas chamber is coupled to a gas storage chamber in the tub. When the water is injected into the washing tub, the mouth of the air storage chamber is quickly closed. As the water level rises, the water level of the air storage chamber also rises, and the closed air pressure also increases, and the corrugated diaphragm 2 in the water level switch is pressurized and swells. The push rod 3 is moved to change the contact 4, thereby achieving automatic switching.

Through the above introduction, I believe that everyone has a comprehensive understanding of the fully automatic washing machine. For people, fully automatic washing machines are the first choice when purchasing washing machines. Then, in the daily use process, if the automatic washing machine fails, you can refer to the above maintenance steps.
