With the increasing number of electrical appliances in the home, its sanitary status has also received more and more attention from people. The cleaning and maintenance of home appliances has gradually been included in the scope of the Spring Cleaning. Recently, relevant experts said in an interview with this reporter that consumers still have certain misunderstandings about home appliance cleaning. At the same time, the usage rate of home appliances during the Spring Festival is several times higher than usual, and early cleaning and maintenance are necessary. Therefore, the necessary operational knowledge must also be kept in mind.
air conditioning
There are two main points in the cleaning of air conditioners: one is the heat sink and the other is the filter. Use air-conditioning special disinfectant to spray it on the air-conditioning heat sink, the stain will flow out automatically along the drain pipe; the filter net can be removed by yourself or with ordinary detergent or directly rinse with water, but be careful not to use force Or wash to prevent deformation of the filter.
Use a soft cloth or a special cleaning cloth to clean the air-conditioning panel and gently wipe it on the surface, then wipe it with a clean soft cloth.
Air-conditioned outdoor units are mostly suspended in the air, and long-term wind and sun, will also deposit a lot of dust. Especially if the consumer feels that the air conditioning refrigeration efficiency is low, it is more necessary to clean the outdoor unit. However, the structure of the outdoor unit is relatively complicated, and the cleaning work needs to find the professional maintenance personnel of the brand after sale to complete the door.
refrigerator
Many refrigerator products introduced in recent years have been strengthened in sterilization and antibacterial functions, but in daily use, it is best to clean and disinfect the refrigerator regularly. It is best to use a special refrigerator cleaner inside the cleaning refrigerator, and wipe it with a soft, soft towel and a refrigerator cleaner. You can also use a more ecological method, put the soft towel in the vinegar and then wipe the inside of the refrigerator. It can also effectively remove dust, decontamination and prevent the production of microorganisms. After cleaning, you can put a small box of soda in the refrigerator. It keeps the smell in the refrigerator fresh.
When cleaning the refrigerator, don't forget the sealing strip of the refrigerator door. This part is easy to hide dirt due to contact with the outside world. It needs to be cleaned from time to time. It is generally recommended to use a soft towel soaked in alcohol to wipe it.
Microwave oven
The cleaning of the microwave oven is very simple. Put the detergent into a heat-resistant container, add a little water (if the microwave has an odor, you can add a slice of lemon), stir it, put it in a microwave and heat it for 3-4 minutes to let the detergent The water is fully evaporated and the microwave is filled with steam. Then take out the turntable and turntable bracket first, then use the rag to clean the microwave oven with the detergent water in the container. Finally, wipe the inner wall completely with clean water to avoid contamination of the food with detergent residue, and then use a clean cloth. Gently wipe the outside of the microwave oven and you're done.
Drinking fountain
Although the construction of household water dispensers is not complicated, the whole process of cleaning and disinfection is actually very professional. Summer disinfection is usually 1 or 2 times a month. First, cut off the power of the water dispenser, then insert the 5 liter water bottle vertically downward into the machine, turn on the faucet until the water is released, then close it, then take out the water bucket, clean the outside of the water dispenser and the base; then, pour the special cleaning and disinfecting solution into the storage water. After the tank, after 10 minutes, turn on the two taps until the disinfectant is discharged. Remember to unscrew the drain valve on the back or bottom of the machine and drain the disinfectant from the dispenser. Finally, rinse repeatedly with boiling water or purified water several times, tighten the drain valve, and the disinfection procedure is completed.
Flat screen TV
One of the principles when cleaning flat-panel TVs is that you don't have to manually remove the flat-panel TV. Because the CFL inverter in the backlight assembly may still have a high voltage of about 1000 volts even in the off state, this high voltage can cause serious personal injury.
Both the LCD screen and the plasma screen are quite fragile. Avoid strong shock and vibration and do not apply pressure to the screen surface. When cleaning the LCD TV, gently wipe the stain with a soft cloth dampened with a little water. Do not spray water directly onto the surface of the display, as the water will enter the LCD TV and cause a short circuit. If moisture has entered the TV, it should be placed in a warmer place to allow the water and organic compounds to evaporate.
Scrubbing the plasma screen with water can cause damage to the plasma TV. It is best to use a special cleaning solution or gently wipe it with a dry soft towel. After cleaning, let stand for 30 minutes, then energize to remove moisture.
water heater
After the electric water heater is used for a certain period of time, a large amount of scale will be formed inside. When the scale is thickened to a certain extent, not only the heating time is prolonged, but also the cracking occurs, the inner tank has some damage, and the heating time is prolonged. The amount of water discharged is reduced. Some electric water heaters are equipped with a drain valve, which can be drained according to the instructions. If there is no drain valve, you need a professional to clean. Long-term use of gas water heaters and solar water heaters should be regularly inspected, cleaned and maintained by professionals.
washing machine
At present, many drum washing machine products on the market have self-cleaning function. Some products use a high-temperature 80°C program to perform a full-time washing process, which can complete a self-cleaning process. Some products also have a barrel drying function, which can be dried by high-speed rotation of the dewatering barrel. , inhibit mold.
As for many washing machine products that do not have self-cleaning functions, consumers need to find ways to clean them. Some brands provide after-sales service for the door-to-door disassembly washing machine tank cleaning service. You can also purchase a special high-sterilization washing machine tank cleaner. Pour the cleaning agent into the detergent addition tank and clean it in the normal washing standard mode. If you feel that the washing machine is dirty, you can also choose to pause after the water inflow process is completed, let the detergent soak for a while, and then start the program.
Wall hob
The increase in the number of household heating districts has also increased the penetration rate of gas fireplaces. However, the newly released survey results show that frequent maintenance and high maintenance costs are the problems that consumers are reflecting in the use of gas fireplace products. Aunt Li, a resident of a residential area in Haidian District, Beijing, complained to the reporter: "I also said that the original wall-hung boiler in our community is an imported brand. This has not been used for three or four years. The noise is particularly loud when it is started recently. It has to be repaired. ."
The person in charge of a gas wall-hung boiler production company said that the use and maintenance of gas-fired boilers is comparable to that of ordinary household appliances such as TVs, refrigerators, and air conditioners. This is the root cause of many misunderstandings caused by consumers. TVs, refrigerators and other products can maintain normal operation even if they are not cleaned and maintained. However, wall-hung boilers are special mechanical devices that integrate water, electricity, gas and other media into one, and are highly integrated. The technical principle is relatively complicated. Need to go through a factory with professional technical background
The fine commissioning of the engineering staff can be put into use and normal operation. Due to its complex nature, the process is very similar to that of a car. It needs to be inspected, maintained and maintained after a long period of high-intensity operation in the heating season. Otherwise, it may affect the service life of the internal components of the boiler and the overall performance of the equipment.
Wang Weidong, the world's first manufacturer of wall-hung boilers, general manager of China's Weineng China, further explained that as a highly integrated special equipment, the normal operation of wall-hung boiler products is affected by various factors such as gas quality, water quality and voltage. Regular inspection, cleaning and maintenance of gas boilers can effectively reduce the load on main components such as pumps and heat exchangers, reduce the wear of operating components, and reduce the failure rate of equipment, thus making the boilers run more smoothly. Therefore, he believes that while promoting product promotion, the company has the responsibility to lead consumers out of the cognitive misunderstanding of the after-sales service of the fireplace through various propaganda forms, so that they can form a sense that “the wall-hung boiler needs regular maintenanceâ€, and even take the initiative to Manufacturers seek maintenance services.
The reporter learned that the current non-standard after-sales service of some small domestic enterprises is also a major reason for restricting the development of the domestic boiler industry. In order to reduce costs, some enterprises outsource the after-sales service of the products to maintenance points that lack relevant qualifications and service capabilities, and lack the corresponding supervision and management of the service quality of the maintenance points. Therefore, it is difficult to form a unified after-sales service standard, and even for profit. Deliberately exaggerating the problem of failure and charging high maintenance costs, resulting in deeper misunderstandings of consumers and affecting the further healthy development of the industry. Wang Weidong said that only the company attaches importance to the construction and improvement of the after-sales service system, and provides consumers with after-sales service of “responsible for home and professional home†to promote the further development of the fireplace industry in China.
Generally speaking, if the user feels that the noise of the fireplace is larger and more expensive than before, and the water temperature of the same firepower is lower than before, it means that the boiler needs maintenance; in addition, it can be judged according to the use time, the product usually Maintenance is started after one or two years of use, and the frequency of maintenance will be about once a year.

Cleaning effect is difficult to identify the most reliable after-sales
Ms. Jiang, who lives in Xicheng District, Beijing, said that when she bought water at the water station, the owner of the water station said that she could clean the water dispenser for free when she bought 20 barrels of water. I didn’t expect the water dispenser to just disassemble the water dispenser and use water and cloth to bring water. Wipe the mouth and base, and say that it is cleaned. In the interview, some consumers also reported that although they know that home appliances also need maintenance, they do not know how to carry out cleaning and maintenance, and they do not know what institutions can provide such services.
It is understood that the relevant national standards and standards issued by the household appliance cleaning industry are: GB19210-2003 "Air Conditioning Ventilation System Cleaning Specification", SB/T10543-2009 "Room Air Conditioner Disassembly Cleaning Maintenance Specification", SB/T10594-2011 Central Air Conditioning Ventilation System Cleaning Industry Technical Management Specification. In 2011, the cleaning service standards for refrigerators and washing machines were officially established in the Ministry of Commerce, but neither of these standards has been introduced.
According to the requirements of air conditioning cleaning service specifications, in addition to checking the safety of the power line, air conditioning cleaning also cleans important components such as filters, evaporators, and condensers. The specifications for refrigerators and washing machines being drafted are clearly required. In addition to the appearance of the refrigerator, the refrigerator also involves the cleaning of the internal freezing and refrigerating rooms; all kinds of household appliances must be tested for the running performance of the whole machine during the cleaning and maintenance process.
"Household appliance cleaning is not a temporary job. It can be used for simple training. Home appliance cleaning should be found in the production service or sales company's authorized maintenance service department. It will be more secure." Wang Yan, deputy secretary general of China Household Appliance Service Maintenance Association Consumers should report directly to the production or sales companies, they will send a list to the relevant special maintenance service department; or go to the official website of the production or sales headquarters to find their unified service and repair calls, also according to the regulations Single; or go to the China Household Electrical Appliances Service Maintenance Association website for enquiries; you can also go to the product counter of a large or chain store to ask the specialists.
â— Tip 2
Do not wash and wash the product
Dr. Li from a hospital in Beijing told reporters that once he called a street "guerrilla" downstairs to clean the range hood at home, after the dismantling, the man said that there were several parts that were broken, Li The doctor agreed. I did not expect that the range hood after the washing and unloading would not be used for a long time, and the company’s after-sales service personnel said that the parts had not been replaced, but the improper installation caused the machine to malfunction.
It should be said that the concept of household appliance cleaning was first started by the range hood, and was popularized by the street "guerrillas", but Wang Yan told reporters that this also caused people's misunderstanding. On the one hand, people think that there is no technical content in household appliance cleaning, and it should not be charged at a high price. On the other hand, it is considered that the range hood should be regularly removed and washed.
In fact, including washing machines, range hoods, products that need high-speed rotation during work should not be washed and washed. For example, many consumers have reported that the range hood has not recovered from its original performance. Because the motor is in high-speed rotation during the operation of the range hood, the requirements for mechanical dynamic balance are very high, and the washing and unloading will seriously damage the dynamic balance, causing noise, jitter and malfunction. In addition, unprofessional disassembly will increase the machine. Part of the gap, the performance of the range hood will be greatly reduced.
So how to solve the cleaning problem of these products. Wang Yan said that on the one hand, enterprises are using various technical means to reduce the pollution of products. For example, some washing machines are equipped with automatic drying function of washing tubs, and some range hoods also have automatic washing and cleaning functions. In addition, people can also clean them with professional chemicals, which can be purchased at the supermarket or purchased from the door-to-door service personnel.
