Is The Self-cleaning Function Of The Washing Machine Cylinder Really Useful

Translated from: Jilin Daily

Washing machines are essential appliances for every household. With the continuous development of technological products, fully automatic washing machines have a new function - cylinder self-cleaning. Regular cleaning of the washing machine can effectively remove residues such as bacteria, mud, and scale, which is beneficial for clothing hygiene. But can the self-cleaning function of the cylinder really do a good job of self-cleaning? How to do daily cleaning for a washing machine without a self-cleaning function? In this issue of verification, the reporter invited experts to conduct science popularization.

1, What is the principle of the self-cleaning function of the cylinder?

Zhang Xinming: The principle of the self-cleaning function of the drum washing machine is thermal sterilization. When the washing machine rotates at high speed, the dirt on the interlayer or drum wall is cleaned by high water temperature water flow, achieving the purpose of self-cleaning. The principle of a wave wheel washing machine is that the water flow collides with the cylinder wall. When the water flow runs at high speed, the wind generated by the rotation of the inner cylinder dries the inner wall of the washing machine, ensuring that it remains clean.

2, Can tube self-cleaning really do a good job of cleaning?

Zhang Xinming: The self-cleaning function of the washing machine cylinder is useful, and it mainly has the following benefits.

Removing residues: The self-cleaning of the washing cylinder can effectively remove residues inside the washing cylinder, reducing the breeding environment for bacteria and mold.Eliminating odors: After prolonged use of the washing machine, moisture and residue can accumulate in the washing drum, producing odors. The self-cleaning function of the drum can eliminate odors.

Protective clothing: Regular use of the self-cleaning function of the cylinder can prevent secondary contamination of residues from laundry and protect clothing from being clean and hygienic.

Extending service life: By regularly cleaning the inner cylinder of the washing machine, it can effectively protect the internal parts of the washing machine, avoid problems such as blockage and corrosion that affect its service life and washing effect.

3, How to do daily cleaning for a washing machine without a self-cleaning function?

Wang Lei: When a washing machine does not have a self-cleaning function, it can still be cleaned properly. The specific steps are as follows.

Add cleaning agent;

Execute normal washing procedures;

After all the detergent is dissolved, pause or close the washing program;

Soak for at least 1 hour;

Start the full washing program again, and after the program is completed, clean the remaining stains on the inner cylinder with a cloth. If necessary, do not add detergent and perform the washing procedure again.

4, The correct method for cleaning a washing machine:

Wang Lei: The drum washing machine can be cleaned using solvents such as bleach and hydrogen peroxide. The specific methods are as follows.

When using bleach for cleaning, first put half a bucket of clean water into the washing machine, and then add about 300-400ml of bleach to slowly generate foam. When the dirt in the inner cylinder is quickly removed, put another water to thoroughly clean the inner wall of the cylinder;

When using hydrogen peroxide to soak and clean, adjust the washing water level to the maximum, add about 200 milliliters of hydrogen peroxide, add an appropriate amount of laundry detergent, and let the washing machine stir normally. After foaming, stop and soak for about 3 hours before discharging the sewage;

When using professional cleaning agents to clean, first find a large bucket, add half a bucket of clean water, and mix evenly into the washing machine. Then start the washing machine normally, mix for 20 minutes, and discharge the sewage;

When using rice vinegar and baking soda to clean, soak the towel in 200 milliliters of rice vinegar, throw the towel into the washing machine and shake it dry. Then let it stand for 1 hour to soften the dirt with the rice vinegar. At the same time, pour the dissolved baking soda into the drum, turn on the washing machine for 5 minutes, soak for another 2 hours, and drain the sewage.

The wave wheel washing machine is cleaned using external maintenance, cleaning agents, and other methods.

When choosing external maintenance, you can use a screwdriver to remove the impeller, dissolve a small amount of specialized cleaning agent in warm water, and brush the back of the impeller and the lower part of the inner cylinder; When choosing to use a cleaning agent, you can pour warm water from 40 ° C to 60 ° C into the cylinder, add the cleaning agent, and choose the single washing mode for cleaning. After washing, you can soak the water in the cylinder for more than 4 hours. After the sheet-like black dirt is discharged, choose strong washing to complete the washing.
