What Is a Smart Washer?

A fully automatic washing machine is a program set in advance on the computer board. To choose one of the programs when washing, just turn on the faucet and start the washing machine switch. The washing machine will automatically identify and control the water level, and accurately complete the functions of soaking-rinsing-dehydration-automatic drainage. When the laundry is completed, it automatically stops and a buzzer sounds.

Fully automatic

The fully automatic washing machines on the market today are roughly divided into three categories ^[1]

The washing process of the washing machine is mainly to achieve the purpose of washing by pulling dirt into the water under the mechanical action of mechanical drainage, scouring and the like, and the wetting and dispersing action of the detergent. First, the washing liquid filled between the pulsator blades is thrown at high speed towards the barrel wall under the action of centrifugal force, and rises along the barrel wall. At the center of the pulsator, a low pressure area is formed due to the liquid being thrown out, and the washing liquid flows back to the vicinity of the pulsator. In this way, a vortex is formed around the pulsator axis around the pulsator. Clothing in

Fully automatic washing machines have increasingly become a must-have household appliance for decoration owners. This washing machine saves people the tediousness of washing clothes in daily life.

A look: Look for scratches, abrasions, and warpage of plastic parts.
Second test: Connect the power, turn on the power switch, and perform test operation of each program according to the instructions to see if the operation is stable.

Common faults and solutions of automatic washing machines:

1, more than water

a, In general, the inlet valve spool is stuck and cannot be reset after the power is turned on, resulting in continuous water inflow. In this case, replace the inlet valve first;

b. If the fault is not resolved, the problem lies in the water level switch. When the water level switch is used for a long time, the water level switch can stop entering the water, which causes the water to enter more than one time. At this time, the water level switch should be replaced;

c. If the pressure tube is broken due to wear and tear over a long period of time, or if the pressure tube is in poor contact with the water level switch and the outer gas valve, or the air leaks, it may cause water to enter, because the computer board is not under pressure, the water level switch does not work. The misunderstanding is that the water level is not stopped. At this time, the pressure pipe should be checked for wear and tear, and the two joints for poor contact or disconnection.

d. Due to a long period of use, foreign matter has blocked the mouth of the gas nozzle, and the pressure cannot be transmitted to the pressure switch. At this time, the large nut should be unscrewed, then take out the inner barrel, and remove the foreign material that blocked the gas nozzle.

e. If everything is invalid, you should try to replace the computer board, because all actions are controlled by the computer board.

2, no water

a. Turn on the power, and the ear is close to the water inlet valve for a "buzzing" sound. If so, check whether the tap water is cut off, close the faucet, and unscrew the water inlet connector to check whether the filter of the water inlet valve is clogged with foreign objects. The filter is pulled out for cleaning. If the problem is not solved, the water inlet valve should be replaced. The valve core of the water inlet valve may be stuck and cannot be opened.

b. If the water inlet valve does not have a "buzzing" sound, try replacing the computer board at this time. The problem may be the computer board.

3.No dehydration

a. First check the safety switch. Turn on the power program of the washing machine to the dehydration state. Press the safety switch brake arm to the lowest level with your hand or tool. If the computer board alarms and the digital tube displays "E1", you should replace the safety switch or motherboard;

b. If the brake arm of the safety switch can be dehydrated normally by pressing the hand or tool, it means that the power-off distance of the safety switch is too low, and the safety switch should be replaced at this time;

c. In the dehydration state, only the pulsator rotates and the inner bucket does not rotate. At this time, check whether the tractor has separated the clutch pawl and ratchet of the clutch. If it is not possible, the adjustment lever nut on the drain valve may be loose and worn, which will cause it to open. The distance is not enough. At this time, the distance of the adjusting lever should be readjusted so that the clutch pawl and the ratchet wheel can be separated.

4.Undrained

a. Q198, Q268: First check whether the adjusting rod nut on the drain valve is loose, which causes the tractor to fail to pull the drain valve core and cause non-drainage. At this time, fix the nut so that it can pull the drain valve core;

Q818, Q828: First check whether the cable of the tractor is loosened with the drain valve;

b. If the nut is not loose or the cable is not loosened, the tractor may be damaged and the drain valve core cannot be opened. At this time, the tractor should be replaced;

c. It is also possible that the debris in the drain valve is blocked to cause non-drainage. At this time, the drain valve valve cover is unscrewed and the debris is removed;

d. If it has not been solved, the computer board may be damaged. You should replace the computer board.

5.There is noise in washing

a. First identify where the sound comes from. If it is below the pulsator, first unscrew the pulsator screw and remove the pulsator to see if there is a foreign object below it. Because the washing machine has been used for a long time, if you do nt pay attention to it during normal laundry, it s inside the pocket Some small things such as coins may drill into the bottom of the pulsator along the gap between the pulsator and the inner tub, causing the sound of the pulsator hitting foreign objects during washing. At this time, you should remove the foreign objects. If you cannot get out, you can turn the entire washing machine upside down Easy to remove or remove inner bucket. In addition, users must be warned that they must remove coins and other items from their pockets when washing clothes.

b. If the sound comes from the bottom, the problem may be with the motor or the clutch. At this time, you can take off the V-belt, and then turn it on. If the noise is eliminated, the clutch is damaged. Otherwise, it is a problem with the motor and it should be replaced.

6, dehydration with noise

a. First check whether the underwear of the bucket is placed on one side, and put away the dehydration and shaking, and there is a noise. At this time, you should open the cover and place the clothes evenly;

b. Check whether there is any foreign matter between the inner bucket, the pulsator and the outer bucket in the same way as there is noise in the washing, if any foreign matter is removed;

c. It may be that the adjusting rod nut on the drain valve is loose or worn, resulting in insufficient opening distance, causing the ratchet pawl of the clutch and the ratchet wheel to cause strange noises during rotation. At this time, the position of the adjusting rod should be adjusted;

d. Otherwise, the problem lies with the motor or clutch.

7.Can't connect power

It may be due to improper use of the user that the computer board is flooded with water or moisture, which causes the computer board to malfunction due to a short circuit. When the power is turned on, the reset coil of the power switch is instructed to cut off the power. At this time, the computer board should be replaced.

8. Drain while entering the water

a. First check whether the valve core of the drain valve is stuck in the power off state. You can see if the valve core rod is in place, otherwise the internal spring may be stuck. At this time, the valve cover should be unscrewed and checked for foreign matter stuck or damaged. Replace it.

b. If the drain valve is normal, check whether the traction rod of the tractor is in place, and whether it is flexible to pull and retract the traction rod by hand. If there is a jam, it means that the inside of the tractor is damaged and should be replaced;

c. If the tractor is normal, whether the tractor has already been activated under the state of water supply, and the drain valve core is shaken to drain water, which indicates that the computer board program has been disordered and the computer board should be replaced.

9, the motor is running weak

a. First check whether the belt is worn, pinch with two fingers. If the two sides of the belt can touch, the belt is worn. At this time, you can adjust the position of the motor and tighten the belt. However, if the belt is too worn or the motor position is adjusted, Replace the belt if it cannot be resolved;

b. If the belt is normal, try replacing the capacitor at this time;

c. If it has not been resolved, the problem may be on the computer board and the thyristor controlling the motor is damaged. At this time, you can measure whether the voltage is normal when the motor is running. If abnormal, you should replace the computer board;

d. The motor is damaged. At this time, the motor should be replaced.

In addition, most automatic washing machines are equipped with a waterless detection program. During maintenance, the machine can be tested without water intrusion or can be demonstrated to users.

With a list of wearing parts of washing machine:

Water inlet pipe, drain pipe, overflow pipe, knob, safety switch, triangle tape, dehydration leather bowl assembly, drainage valve core, compression spring, torsion arm spring, drainage puller, brake puller, spring leaf, safety cover, transparent cover, Damping spring assembly, rubber plug, wire cutting filter.

First, is it better to use a pulsator or a roller?

Before choosing a washing machine you need to know your effective needs, the more specific the better. For example, whether your clothes are high-grade, how dirty they are when washing, how often they are changed, how much is the budget, where is the washing machine, how big is it, how sensitive is it to noise, etc. Read the analysis above and compare yourself Demand, you'll make the right judgment for you. If you have more high-end clothes and always wash them at home, instead of sending them to a laundry outside, and have a rich budget, plenty of housework time, and do nt care about noise, then you can choose a drum washing machine. If you do nt have a lot of budget and do nt have high-end clothes, and they are all dry-cleaning in the dry cleaners. When washing at home, you need to wash faster and not be noisy.

Second, is it better to use a stainless steel inner barrel or a plastic inner barrel?

The material of the inner barrel is not necessarily stainless steel. In fact, there are many types of plastics. Many polymer materials are not cheaper than steel materials and their durability is not worse than stainless steel. The salesperson will definitely say that stainless steel is better than plastic inner tubs in the introduction. Most people also think so, although there is no theoretical basis, let s take a step back. Assume that the stainless steel inner tub is better than the plastic inner tub. Most of the accessories are plastic. At that time, other plastic accessories are broken and the washing machine cannot be used. So what good is it to keep the stainless steel inner barrel? Nowadays, stainless steel inner drum washing machines are generally more expensive than plastic inner drums. There is really no need to buy a stainless steel inner drum washing machine.

3. Can the salesman say "dry weight" as an important basis for selection?

When the salesperson introduced the washing machine in the shopping mall, he had to mention 100% of the washing machine with a weight of dry clothes that you want to buy. As a result, everyone chose it, thinking that it was based on the weight of the clothes. How much practical reference value? Because there are too many types of clothing, we ca nt simply measure it by the weight of dry clothes. We should not pay too much attention to this aspect, but should put it in other aspects. For a pulsator washing machine, the diameter of the inner tub, as well as the shape of the pulsator and inner tub, are more important. In fact, because of patent restrictions, the main difference between brands is here, not what controls the program and appearance. on.

For a drum washing machine, the inner barrel diameter must be so large that it can only be reduced by depth. This is determined by the washing principle of the drum washing machine. If this kind of washing machine is loaded with too much clothes, there is no way to wash it. Because it relies on three raised bars in the laundry bucket to take the clothes to a high place, and then free fall to do the laundry. If it is full of clothes, it won't wash at all.

When buying a washing machine, you must first understand the type of washing machine. Today, there are three types of washing machines on the market: drum type, pulsator type and stirring type. They all wash clothes by chemical action, mechanical action, time and temperature. Among them, the stirring type washing machine has a very small share in the market today. As far as drum washing machines and pulsator washing machines are concerned, the two differ greatly in terms of the degree of cleanliness of clothes, power consumption, and time spent washing. Cleanliness and damage rate: The drum washing machine is rotated by the drum in the forward and reverse directions. The clothes are raised by the ribs and fall freely by gravity. Simulating hand rubbing, the washing degree is uniform, the clothes loss rate is low, and the clothes are not easy to entangle. High-grade clothes such as silk and wool can be washed. The drum washing machine can also be heated, which can activate the biological enzymes in the washing powder and further improve the washing effect.

The pulsator washing machine relies on the eddy current generated by the high-speed operation of the pulsator to impact the laundry. The laundry is washed by the action of detergent. Although the degree of cleanliness is higher than that of the drum type, due to the large mechanical force, the laundry is tangled and knotted , The degree of wear is large.

Water and electricity consumption: The washing power of the drum washing machine is generally around 200 watts, and the dehydration is proportional to the rotation speed. If the water temperature is increased to 60 degrees, it usually takes more than 100 minutes to wash once, and the power consumption is about 1.5 degrees. The time is related to the texture of the clothes. It takes at least 40 minutes. This requires the user to prevent the meter from "tripping" when using the drying function only if the meter is equipped with a 10 amp meter. In comparison, the power of a pulsator washing machine is generally about 400 watts, and it only takes up to 40 minutes to wash clothes, so the power consumption is much smaller.

In terms of water consumption, the drum washing machine is about 40% of the pulsator washing machine. Floor area: The top-loading drum type washing machine has the smallest floor area, about 0.24 square meters. Other drum type and pulsator type washing machines have the same area. The ultra-thin products introduced in the market have saved a lot of space accordingly. Capacity and price: The capacity of the pulsator type washing machine is 2-6 kg, and the drum type is 3-5 kg. Usually, it is mainly 5 kg. In terms of price, the roller type is more expensive than the pulsator type, and 2500 yuan is the boundary between the pulsator and the roller.

After fully understanding the above situation, you can choose the appropriate model according to your actual needs. In addition, because the living conditions, hygiene habits, economic conditions, and lifestyle of each family are different, it is more important to make decisions based on your actual situation. When buying, you should pay attention to the sound level during the washing, whether there is abnormal sound, whether the vibration during dehydration is too large or accompanied by abnormal impact sound; observe whether the appearance and internal structure of the visible part are beautiful and smooth, and there are no damage . Generally speaking, you should choose brand-name products as much as possible. Brand-name products have stable performance, large production and sales volume, good sales, many after-sales service outlets, and high service levels.
