LCD TV and Common Sense of Household Appliances Maintenance
First, the method of correctly understanding the dirt on the screen of LCD TV.
LCD screen is the core part of LCD TV, and it is also the focus of our cleaning. The surface of LCD screen is covered with glass. If dirt is found on the surface of LCD, it should be removed by the correct method.
There are two kinds of stains on the LCD panel, one is dust that should stick in the air over time, and the other is fingerprints and oil stains left by users inadvertently. I want to remove the dirt on the LCD screen. It is best to use soft, non-fibrous materials, such as absorbent cotton, lens paper or soft cloth, and then wipe with a little glass cleaner. Wipe lightly, or the screen will be damaged by short circuit >: It is forbidden to use chemical solutions such as alcohol. Do not use a hard towel to clean the screen surface, so as not to roughen the screen surface and affect the display effect. You can't use rough cloth or paper products. Because this substance will produce scratches. I want to remind you not to spray the cleaning agent directly on the screen surface. It is easy to stay on the screen and cause it. There is a short circuit on the LCD. It will cause unnecessary losses, and the screen cleaning should be quantified regularly. It is also wrong to wash it often, and it will also have some bad effects on the TV screen.
Second, put an end to some bad habits.
When the TV is not turned on, please turn off the LCD screen "Don't turn off the remote control casually" to prevent dust accumulation. Don't use your fingertips to "keep pointing at the screen" or sharp objects to slide on the LCD screen. So as not to scratch the surface.
Keep the use environment dry and away from some chemicals.
Don't put the LCD TV in a damp place. If moisture has entered the LCD TV, it must be placed in a warmer place to let the moisture inside evaporate. At present, LCD screens are all coated with special coating, which makes the screen have better display effect. Hair gel, alcohol and mosquito killer commonly used in summer are sprayed on the screen, and this special coating will dissolve, causing damage to liquid crystal molecules and even the whole screen, which will shorten the life of the whole TV. Therefore, try to avoid contact with moisture and chemicals.
Fourth, safety tips: Do not open the fuselage without authorization.
LCD TV is a new favorite of home appliances recently, which is not only pleasing to the eye, but also has a much longer life than ordinary TV. However, LCD TV should be well "maintained" before it can serve you without trouble for a long time.
But we can't clean for the sake of cleaning. Never disassemble the LCD TV, because the CFL converter in the background lighting assembly may still have a high voltage of 1000V, which may cause serious personal injury.
How to delay LCD aging?
Due to long working hours or strong light irradiation, the LCD screen will age or burn out. The display screen is yellow and dark, which seriously affects the viewing quality. Therefore, we can't take it lightly and avoid the following common practices:
1, if you don't watch TV for a long time, don't turn off the TV, which not only consumes electricity, but also may burn out the LCD TV.
2. Displaying the same picture for a long time will cause some LCD pixels to overheat, leading to bad spots on the TV.
3. Put the TV in the sun to get rid of the moisture: strong light will accelerate the aging of the LCD screen.
Refrigerator maintenance skills of household appliances
First, a friendly reminder.
1, the refrigerator should not be placed against the wall but should be away from the wall 10 cm or so; 2. Pay attention to the fact that the tilt of the fuselage should not exceed 45℃ during handling. 3. When handling, keep the box upright, don't put it upside down or horizontally, and don't grab the door handle or drag the condenser to avoid damage.
Second, the refrigerator power supply is connected at three points.
1. Before touching the power supply, check whether the voltage specified on the nameplate is the same as that of the household appliances, and then use it.
2. The refrigerator needs to be equipped with a separate power supply circuit, using a special socket, and can't share the same socket with other electrical appliances, otherwise it will cause bad accidents.
3. After installing the grounding device and meeting the above conditions, power on the refrigerator.
Three or five correct unannounced visits to refrigerators.
1, the refrigerator should be placed away from stoves, radiators and other heat sources, and at the same time avoid direct sunlight. This is good for heat dissipation.
The refrigerator should be placed in a place with low humidity.
The refrigerator should be placed in a well-ventilated place. The back of the refrigerator should be more than 10 cm away from the wall, and the top should have a height space of more than 30 cm. There should not be too many sundries around. The refrigerator should be placed in a stable place on the ground. Otherwise, the compressor will vibrate and make a lot of noise when it starts, which will shorten the service life of the refrigerator for a long time.
5. Don't put heavy objects or excessive sundries on the refrigerator, especially other electrical appliances.
What should I pay attention to when using a new refrigerator for the first time?
1, read the instructions carefully before use, and then turn on the power.
2. When the refrigerator is used for the first time, the running time should not be too long, and it should be carried out intermittently to give each part of the refrigerator a running-in process.
3. When the new refrigerator starts to work, it is not advisable to store too much food, and then gradually increase the food storage with the increase of working hours of the refrigerator.
1, the refrigerator should try to reduce the number of times to open the door and reduce the overflow of cold air.
2. The power supply voltage fluctuates greatly. In case of repeated power failure, the refrigerator should be suspended and the power plug should be unplugged to prevent the compressor from burning out. Don't start the compressor immediately after the refrigerator stops. Stop for 2-5 minutes before starting. In case of temporary power failure, unplug the refrigerator first; In case of power failure, the frequency of opening the ice door should be reduced. When the refrigerator door is closed, the food can be kept fresh 15-20 hours.
3. In the process of using the refrigerator, you should pay attention to its refrigeration performance, and then choose a refrigerator temperature that is most suitable for your home. Changing the knob of the temperature controller can change the temperature of the refrigerator.
Sixth, clean the refrigerator.
The refrigerator must be kept clean and dry, and dust, dirt and odor should be removed frequently. Pay attention to the following points when cleaning the refrigerator:
Don't clean the refrigerator with acid or alkali solution.
Don't wash the box with organic solvent. .
Don't wash the refrigerator with hot water.
Don't rinse the shell and inner container of refrigerator with water.
Don't scrape dirt with sharp tools.
Therefore, when cleaning the refrigerator, you should dip a soft cloth in warm water or neutral detergent, such as soapy water, clean the shell and inner container of the refrigerator, brush the dust on the condenser with a soft brush, or vacuum with a vacuum cleaner. If there is too much scale on the box, you can stick toothpaste or washing powder on the towel and wipe it with water. After cleaning, after the refrigerator is completely dry, put the food in the refrigerator and start working with electricity.
Tips for deodorizing refrigerator.
Wipe the box with a soft cloth, then put half a cup of white wine and close the refrigerator door. After 24-28 hours, the odor can be eliminated. Activated carbon or deodorant can also be added to deodorize.
What should I pay attention to when the refrigerator is stopped for a long time?
Unplug the power plug and keep it safe.
Take the food out of the refrigerator, clean and dry the food boxes, brackets and other accessories and put them back in place.
Open the door, melt the frost on the evaporator, clean the evaporator surface after removing water, and dry it with a soft cloth.
Wipe the refrigerator door seal with cloth purlin, coat it with talcum powder for maintenance, or pad a paper towel at the contact between the door seal and the box body to avoid the door frame adhesion caused by long-term closure.
Adjust the thermostat knob to the position of strong cold point, so that the thermostat spring is in a relaxed state.
Open the door of the box and let it dry 1-2 days. It is forbidden to cover the refrigerator with a plastic cover for collection.
Don't pile up heavy objects on the refrigerator when storing, in case the box is deformed or tilted.
How to restore the refrigerator that has been cut off for a long time?
Check before use. If there is nothing unusual, clean the refrigerator. Because the refrigerator stopped for a long time, the lubricating oil sank and became sticky, and the parts were in a state of oil loss. It needs to be started several times when it is used. Plug in the power supply and start it slightly, stop for 3-5 minutes, start for 2-3 minutes and stop for 3-5 minutes. Repeat several times until the lubricating oil becomes thinner when heated. After lubrication, the parts are put into normal use.
How to store and keep all kinds of food fresh in the refrigerator?
1. Preservation of meat: Wash the bought fresh meat with warm water, cut it into several pieces and pack it in plastic bags. Short-term storage for 2-3 days can be stored in the refrigerator at about 0℃; For long-term storage, it can be stored in the freezer below-18℃.
2. Preservation of egg birds: The suitable temperature of fresh eggs is generally 2-5℃, and they can be kept in the refrigerator for about 2 weeks. Never put fresh eggs in the refrigerator.
3. Before poultry is stored, the internal organs must be cleaned, washed and drained, and sprinkled with a small amount of fine salt. Generally, it is advisable to store whole poultry. Finally, poultry should be packed in plastic bags and tied tightly, and stored in a freezer at about 0℃ for 1-2 days; It can be stored in the refrigerator below-18℃ for about two months.
4, the preservation of fish, before storage, scales, gills, viscera and blood should be removed, washed, dried, salted and put into plastic bags. Short-term refrigeration "eat within 1-2 days" should be refrigerated; Long-term storage "1 month" should be stored in the freezer.
5. Fresh shrimp storage: If the fresh shrimp is eaten within one day, it can be cleaned, put into plastic bags and put into the refrigerator. Long-term preservation is better than cooking fresh shrimps and freezing them in the freezer. The shelf life of this method is one month.
6. Storage of vegetables: Generally, vegetables should be washed, dried, put into plastic bags and tied tightly before storage. Put the processed vegetables into the cold storage room with the temperature of 0- 10℃.
7. milk storage: milk is stored in the refrigerator and can be stored at 0-2℃? 1-2 is around the clock. The sterilized emulsion can be stored for 5-6 days at 2℃. Never store milk in the refrigerator. Because the quality and nutritional value of frozen milk will be affected.
General knowledge of washing machine and home appliance maintenance
Generally, newly bought washing machines should be cleaned with special detergent for washing machines every three months after being used for half a year. Families often clean washing machines, which can be synchronized with the disinfection of clothes and towels. That is, when soaking clothes, towels and other items for disinfection, directly pour the items to be disinfected together with the prepared disinfectant into the laundry bucket for soaking for 30-60 minutes, and then rinse them with clear water. This can not only disinfect clothes, but also remove the dirt from the washing machine. When the washing machine is not used at ordinary times, it is best to open the cover of the washing machine frequently to keep the inside of the washing machine dry. Take out the washed clothes to dry immediately, and never leave them indoors.
Washing machines that have been stopped for a long time do not need maintenance. First of all, remove water and keep the machine clean and tidy. It is best to put it in a dry place where there is no corrosive gas and strong acid and alkali erosion, so as to avoid rusting of metal parts and reducing insulation of electrical components. For washing machines with no oil holes in the impeller shaft, the washing machine should be oiled once to prevent corrosion. The washing machine stored for a long time should be covered with plastic film or cloth to avoid dust erosion and keep the washing machine bright and tidy. It is best to start trial operation every 2-3 months to prevent parts from rusting and motor windings from getting wet. Energization is also a means to dry the winding, which can avoid the failure caused by too long downtime. Washing machines should not be exposed to direct sunlight for a long time, especially plastic devices, so as to avoid fading and aging.
For drum washing machines, there is generally no abrasion and entanglement when washing clothes, so you can wash all kinds of clothes with confidence. As long as you pay more attention before washing, you should carefully check the label on the clothes before washing, and choose the corresponding washing procedure according to the texture of the clothes, such as cotton, chemical fiber and wool. Secondly, we should classify the colors of clothes, and wash the newly bought colored clothes separately as far as possible to see if they fade. Worn buttons, pins and metal ornaments on clothes must be removed before washing, and zipped clothes should be zipped. The dry cleaning capacity of a washing machine with the function of drying clothes is half of the washing capacity, so care should be taken not to prevent too much clothes during drying to avoid wrinkles after drying. Finally, it is best to open the glass window of the washing machine a little after the washing machine is used up, which can prolong the service life of the sealing ring and is also beneficial to the discharge of water in the machine. Drum washing machine must use washing powder with low foam and high detergency, and it is best to heat and wash dirty clothes.
Maintenance skills of household appliances air conditioner
One, the use of air jump device two taboos.
1, avoid using the socket with other appliances. 2. Avoid changing the operating state of the heat pump air conditioner during operation.
Second, a friendly reminder.
1, clean the air conditioner with a soft cloth and a small amount of neutral detergent, and the water temperature should be lower than 40℃ when cleaning, so as not to cause the shell and panel to shrink or deform.
2. The indoor air inlet filter should be cleaned every 20 days, and the outdoor unit should be dusted regularly.
3. If the air conditioner is found to be faulty, it must not be used reluctantly to prevent the fault from expanding. Ask professionals to repair it in time.
Third, the common sense of air conditioning.
1? Correct selection of the optimal temperature of air-conditioned rooms should be as close as possible to human comfort. From the point of view of health care, when using air conditioning, the indoor and outdoor temperature difference should not be too large, generally 8 degrees Celsius is appropriate, and it is best not to exceed 10 degrees Celsius, so as to avoid unexpected situations such as catching a cold in and out of the room.
2, the use of air-conditioned rooms, due to long-term closure, it is easy to cause indoor air quality is getting worse and worse, which has a great impact on people's health. Therefore, we should always open doors and windows and change indoor air to avoid endangering people's health in a long-term hypoxia environment.
When using air conditioning in summer, the indoor unit should choose to supply air in the horizontal direction, and when using air conditioning in winter, it should supply air obliquely below, which is beneficial to make the temperature of the whole room as balanced as possible and reduce unnecessary energy loss to a certain extent.
4. Because of the dehumidification function of air conditioner, it is easy to make the indoor air too dry when using air conditioner in summer. Being in an excessively dry environment for a long time is easy to make people sick. Therefore, in addition to rainy weather, places with high air humidity or already high air humidity, such as coastal areas, should often spray some water on indoor floors or other suitable places to increase indoor air humidity.
What maintenance work should be done before and after the air conditioner changes seasons?
1, before the season.
Check whether there are sundries around the outdoor unit that affect ventilation, and whether the dust cover covered by the outdoor unit has been removed.
Check whether the power cord, pipe insulation sleeve and wrapping tape are damaged or loose.
Check whether the power supply, power plug and socket are normal.
Check whether the filter screen is installed and whether there is any dust to be removed.
Check the remote control and battery.
2. After the use season? .
Before stopping using, set the air conditioner to air supply state and ventilate continuously for 3-4 hours to dry the machine; Try to cover the outdoor unit with dust cover after power failure to reduce the erosion of air conditioning caused by wind, rain and sun. Remember to take out the battery in the remote control and keep it safe. Do not drop, press or shake the remote control. Take out the filter screen and air conditioner filter from the machine, clean them and reinstall them.
Common knowledge of water heater and home appliance maintenance
I. Precautions for use:
1, when using the water heater, turn on the power supply, and the indicator light is on, indicating that it is being electrified for heating; When the water temperature reaches the set value, the indicator light goes out, indicating that the power supply is cut off; When the indicator light goes off, it means automatic heat preservation.
2. The electric water heater "storage type" should be filled with water first, and then electrified for heating. In case of water pressure drop or water cut off, it is best to turn off the power supply.
3. The electric water heater is equipped with a faucet and a backflow device. Usually, "blue" means cold water and "red" means hot water. On the temperature regulator of electric water heater, there is a water temperature meter to scale, and usually' I',' II',' III' or signs in English and Arabic are used to indicate low, medium and high water temperatures.
What should I pay attention to when using the water heater safely?
1. The water heater shall be installed by professionals according to regulations.
2. To prevent burns, open the cold water valve first, and then open the hot water valve: when closing, close the hot water valve first, and then close the cold water valve. When in use, let the water overflow before the shower to test the actual water temperature, so as to avoid scalding the skin if the water temperature is too high.
3. When the water valve is turned on and there is no water, turn off the power immediately to prevent damage caused by waterway failure, and use the electric water heater in the case of tap water.
4. Avoid damaging the electric water heater because the water inlet size causes the water outlet temperature to be too high. 5. Strictly prevent installing valves at the inlet and outlet at the same time.
6. When using the water heater in ice period, keep the water in the water heater at a certain temperature to avoid freezing, otherwise it will damage the electric water heater.
7, if the water pressure or battery is too low, should be suspended.
Third, a friendly reminder
1. Select the most economical and applicable capacity according to the population. Under normal circumstances, a family of three can choose 50 liters, and 80 liters can meet the needs of four or five people. 2. When consumers buy gas water heaters, they should check the quantity according to the type of gas at home, because gas water heaters are produced according to the type of gas, including gas type and natural gas type. Never use natural gas at home but buy gas, which will not only cause you economic losses, but also be unsafe.
3. Don't just consider the price when buying gas water heater. Safety should come first. It is best to buy a forced exhaust gas water heater with good safety performance. This product is generally more expensive than in-line 200 yuan.
4. If you buy an in-line gas water heater, you must choose a product with an unsafe combustion prevention device.
No matter what kind of gas water heater you buy, you must buy products from reputable manufacturers when installing, and don't buy brand-name products without quality assurance casually, so as to effectively protect personal safety.
6. No matter what type of gas water heater, the water heater must be installed in the shower faucet compartment. In the past, many accidents were caused by installing a water heater in the shower faucet of a room.
7, the use of gas water heaters, if you encounter a strong wind of magnitude 6 or above, you need to suspend the use to prevent waste gas from flowing backwards.
8. If the elderly or children use the gas water heater to take a bath alone, they must remind the precautions in advance, ask about the safety situation during the activity, and always pay attention to the safety of use.
9. We must strictly control the source and ignition of gas water heaters. When not in use or going out, be sure to cut off the air source and fire source to prevent accidents.
