air conditioning:
Air conditioners that exceed the service life are prone to problems such as water leakage, poor cooling, and no refrigeration, and they are very power-hungry. They are veritable "electric tigers." The air conditioner is used to adjust the temperature, the internal temperature and humidity are suitable for bacterial growth, and the air conditioner is operated in a closed space for a long time, which easily pollutes the indoor environment, causes respiratory diseases, and causes harm to human health.
refrigerator:
After the refrigerator compressor is aged, it not only affects the working efficiency of the refrigerator, but also causes a large noise. If the wiring of the refrigerator is aging, it is prone to safety accidents such as electric shock and spontaneous combustion, and the leaked refrigerant will also cause environmental pollution. Old refrigerator refrigerants are usually made of Freon. Freon is a toxic gas that can affect the indoor environment and cause different degrees of damage to the human body.
washing machine:
When the washing machine is used for a long time, it is prone to problems such as water leakage, short circuit, and heat of the fuselage. Especially in hot weather, long-term operation of the machine will overheat the fuselage and increase the possibility of spontaneous combustion. The components inside the washing machine may cause electric leakage after aging, which may cause the water in the washing machine casing or the washing tub to be charged, which is very dangerous for the user.
water heater:
Electric water heaters that have exceeded the service life, components such as aging, scale thickening, and increased corrosion area will increase the possibility of leakage and pose a threat to personal safety.
Water storage type electric water heater, after long-term use, the surface of the heating tube is prone to scale, which causes heat to be dissipated. The surface of the heating tube will burst and damage, causing electric shock hazard; if it is a ceramic inner water heater, it may be possible to use the magnesium rod for too long. There is leakage.
Microwave oven:
According to the ranking of indoor household appliances radiation published by the China Environmental Monitoring Center, microwave ovens rank first in common household appliances. The microwave oven uses a microwave generator to move the water molecules in the food, and the intense movement generates a large amount of heat energy, thereby generating radiation. Although the outer casing of the microwave oven is made of a metal material such as stainless steel, it can block the microwave from escaping from the furnace. However, if the use time is too long, the sealing property will be weakened, and the electromagnetic wave will sneak out.
TV set:
When the TV set exceeds the safe service life, the picture tube tends to age, and the brightness and contrast of the picture will be greatly reduced, which may cause eye fatigue, myopia, astigmatism, cataract, etc., causing damage to human vision. At the same time, the picture tube contains toxic and harmful substances such as lead, and the X-ray radiation will increase with the aging of the picture tube, causing harm to human health.
