1. Flat-screen TV: Do not disassemble it without permission.

When cleaning a flat-screen TV, one of the principles is to never disassemble it by hand. In addition, both LCD and plasma screens are quite fragile, so avoid strong shocks and vibrations when cleaning, and do not apply pressure to the surface of the screen. When cleaning the LCD TV, use a soft cloth moistened with a little water to gently wipe away the stains, but do not spill water directly onto the surface of the display.

It is best to wipe with a special detergent.

2. Air conditioning: no water should enter important parts.

The air conditioner should be cleaned regularly. The traditional air conditioning cleaning method can only simply flush the filter screen and wipe the surface of the evaporator, and cannot comprehensively clean the gaps and air supply system of the air conditioner evaporator, and the inside of the evaporator is the place where the dust is most seriously blocked and bacteria and viruses are most likely to multiply. When cleaning the air conditioner, use a soft, dry cloth to wipe off the dirt on the air conditioner shell, and be careful not to scrub it with chemicals such as hot water or flammable oil.

Take out the filter of the air conditioner, rinse it with clean water or vacuum the filter, dry it and reinstall it into the air conditioner. In addition, it should be noted that when cleaning the outdoor unit, you can use clean water to rinse the surface of the condenser of the outdoor unit, and cover the hood after drying, and no water should enter other parts.

3. Refrigerator: The inner wall can be protected with glycerin.

The condenser and compressor of the flat-back refrigerator are built-in and do not need to be cleaned frequently. Dust on the surface of the condenser and compressor can be blown off with tools such as air pumps, and should never be scrubbed with water or a damp rag. In general, we should clean the inside of the refrigerator more than twice a year.

When cleaning the refrigerator, turn off the power first, gently scrub with a soft cloth dipped in water or dish soap, and then wipe off the dish soap with water. The inside of the refrigerator can be wiped down with boric acid or disinfectant tissues, and wiping the refrigerator with boric acid can be easily defrosted. The inside of the refrigerator can also be wiped with glycerin to form a thin protective film, so that milk or food residue can be easily wiped off if it gets on the inside wall.

1.Remove the dust filter according to the instructions, and be careful not to touch the metal part of the indoor unit when disassembling to prevent it from being scratched.

2.After removing the air filter, gently pat or use an electric vacuum cleaner to remove the dust. If the dust filter accumulates too much dust, it can be rinsed with water or dipped in neutral detergent with a soft brush, but the water temperature should not exceed 50 or more during cleaning, and washing powder, dish soap, gasoline, banana water, etc. cannot be used to avoid the deformation of the dust filter.

After rinsing with clean water, wipe dry with a soft cloth or put it in a cool place to dry, never expose it to the sun or dry it in an open flame such as a stove, so as to avoid the deformation of the dust filter.

There are a few details to pay attention to when cleaning an air conditioner:

Turn on the air conditioner for 15 minutes before cleaning it, so that the air conditioner can start to cool down and at the same time make the air conditioner evaporator produce condensation. Turn off the air conditioner and cut off the power supply to ensure absolute safety in the cleaning operation. Take out the small tube attached to the detergent bottle, insert it into the nozzle, and spray it evenly from left to right onto the surface of the aluminum heat transfer sheet and coil on the fins of the evaporator to ensure that the cleaning foam completely covers the surface of the evaporator.

You should develop the habit of cleaning your air conditioner regularly, which is not only good for your family's health, but also conducive to prolonging the life of your air conditioner.

Household appliance brother air conditioning cleaning expert tips, air conditioning cleaning and maintenance, is conducive to improving the refrigeration effect, is conducive to shortening the cooling time, reducing the consumption of air conditioners, can prolong the service life of air conditioners, and reduce power consumption. While providing convenience, the exhaust gas, dust, bacteria and other pollutants in the air will accumulate on the evaporator fins of the indoor unit, which will cause the cooling and heating effect of the air conditioner, and more importantly, these dirt and pollutants will breed many harmful molds, which will affect the health of the family if they are not cleaned in time. It usually causes headaches, coughs and other symptoms, which is also often said to be "air conditioning disease", home appliance brother timely air conditioning cleaning, look for it, home appliance brother, completely solve the "air conditioning disease" generation.

In fact, household appliances are the same as other electrical appliances, they also need to be reasonably maintained and maintained, and household appliances also have use restrictions and use cycles, so we should pay attention to the maintenance and maintenance of household appliances to extend the service life, and it is best to clean them up more often, and at the same time, we should also pay attention to proper use, and do not use them excessively in extreme situations.

**The main reasons for the poor cooling effect of the air conditioner are: 1. The external unit of the air conditioner is not running, check whether the compressor is running normally. 2. If the coolant is insufficient, check whether there is a lack of coolant.

3. The water circulation pump is faulty, and there is a lot of water in the pipeline. 4. If the compressor or valve string gas is not a problem with the above inspection, find after-sales service for maintenance.

The service life of general air conditioning products is about 10 to 12 years.

Although it is 12 years old, if the air conditioner is not maintained regularly, the aging of the air conditioner will be accelerated. The debris of the outdoor unit of the air conditioner should be cleaned regularly to ensure that the vents are unblocked. Do not use too much force when cleaning the heat sink of the outdoor unit, because the heat sink is easily deformed after being stressed.

The filter screen of the indoor unit needs to be cleaned frequently, and the dust on the filter screen will make the air circulation of the air conditioner poor and the refrigeration effect will be reduced.

Therefore, when you buy an air conditioner, pay attention to the warranty period of the main components of the air conditioner (such as compressor, indoor unit, etc.). Generally, the warranty period of big brands ranges from 6 to 10 years, of course, the longer the better, after all, the service life of the air conditioner is there.

Overage air conditioner hazards

Exceeding this period is considered to be an overage household appliance. Due to the long use time, over-aged air conditioners are prone to high noise, increased power consumption, slow refrigeration and heating speed, ineffective remote control, and serious odor at the air outlet.

At the same time, because of the long-term exposure to the outdoors, the outer machine bracket is easy to corrode and rust, and the phenomenon of loosening and bending occurs, which has certain potential safety hazards. When the air conditioner reaches service age, users should replace it in time.

Don't turn the air conditioner on and off frequently because the room temperature is at or above the required value, but let the air conditioner be controlled by the temperature controller. When the air conditioner is not in use, turn off the power supply and unplug the power supply.

The service life of air conditioners is generally 8 to 10 years.

Seasonal maintenance of air conditioners:

When the air conditioner is not used for a long time, in order to fully dry the inside of the air conditioner, it should first run in the air supply mode for 4 hours, add some lubricating oil to the fan motor part, then cut off the power supply, and then cover the air conditioner with an envelope, and cover the outdoor body with a protective cover to avoid sun and rain. At the same time, wipe the remote with a clean, soft, dry cloth and remove the battery. When reusing the air conditioner, it is necessary to do a basic cleaning and do an operation test.

In-depth maintenance of the air conditioner:

Professional and technical personnel are requested to carry out comprehensive and thorough cleaning and maintenance of the core components of the air conditioner from the inside to the outside, so as to find the hidden problems of the air conditioner in time, effectively extend its service life, and be healthier and more energy-saving. The in-depth maintenance of the air conditioner is generally sufficient once every 2-3 years.

Five taboos for the use of air conditioners:

Doors and windows are closed for a long time;

lack of ventilation equipment;

Large temperature difference between indoor and outdoor;

The equipment is not cleaned frequently;

The temperature setting is too low.

The General Principles for the Safe Service Life and Recycling of Household and Similar Electrical Appliances, approved and promulgated by the Standardization Administration of the People's Republic of China, stipulate the "retirement" age of household appliances and make clear provisions on the service life and recycling of household appliances. Manufacturers should indicate the safe use period for the household appliances they produce, and stipulate that the safe use period shall be calculated from the date of purchase by the consumer. Within the safety period specified by the manufacturer's trademark, if a safety accident occurs when consumers use household appliances normally, all responsibilities will be borne by the manufacturer.

It is understood that the safe service life indicated on household appliances is clearly indicated to consumers in the form of "manufacturer's self-declaration", and should not be less than the "three guarantees" period of the main parts and components in the "Provisions on Liability for Repair, Replacement and Return of Household Appliances".

Because too frequent replacement is also a waste, therefore, the "Detailed Rules for the Safe Use of Household Appliances", the formulation of the service life will be considered from many aspects. The minimum "shelf life" of household appliances is limited to the average intensity of the average household. In other words, long-term suspension and super-intensive use are extremely special cases and are not considered in the Rules.

Experts remind] overage "home appliances have many hidden dangers."

Household appliances are large durable consumer goods, experts remind consumers that all household appliances have a safe lifespan, beyond the shelf life, should be scrapped, otherwise it will increase potential safety hazards.

According to professionals who have been engaged in home appliance maintenance for many years, when the TV exceeds the safe lifespan, with the aging of electrical components, the TV will have unclear images, trembling and other failures, and the radiation of the TV will also increase. Aging TVs can be subjected to vibrations, shocks, collisions, sudden cooling, sudden heating, as well as excessive dust and dirt in the TV or local overheating caused by short circuits in wires, which can cause CRT**; If the refrigerator is too old, the preservation and sterilization functions will be degraded, resulting in the smell of food and the inability to keep it fresh, and at the same time, the refrigerant will also leak, pollute the environment and endanger health; Overage washing machines often have minor problems such as water seepage, and in severe cases, electricity leakage.

In addition to safety hazards, home appliances that exceed the safe use period will also consume more electricity. Generally, the power consumption of elderly household appliances is more than 40% of the original electricity consumption. For example, if you use a refrigerator for 10 years, it will consume twice as much power as it did when it was originally used.

Reference for the safe service life of household appliances.

Color TV 8-10 years.

Electric water heater. 8 year refrigerator.

12-16 years.

Rice cooker for 10 years.

Air conditioner 8-10 years.

Gas stove for 8 years.

Washing machine for 8 years.

Hair dryer for 4 years.

Personal computer (PC).

6 years microwave.

10 years electric fan.

10 years vacuum cleaner for 8 years.

The service life of the car air conditioner generally follows the service life of the car, and it will not be damaged easily, but the relevant consumables should be replaced regularly, such as refrigerant 134a, such as belts, and the compressor should be replaced at a certain time and kilometers!
