Many households are based on the principle of saving. The electrical appliances are generally broken and repaired. They can't be repaired before they are replaced. The use of electrical appliances for years is likely to bring health and safety hazards. Lu Jianguo, director of the Health Appliance Testing Center of China Household Electrical Appliances Research Institute, said. Component insulation aging, increased fouling, increased corrosion area, etc., will bring danger when used. The following five kinds of appliances are the most dangerous over age, remind everyone to pay attention:
Refrigerator. The national standard stipulates that the safe use life of refrigerators is 10 years. Lu Jianguo said that if the service is overdue, the cooling effect and electrical insulation function will decline, affecting the freshness of the ingredients, causing electric shock risk. The operation sound is too loud, the body is shaking , power consumption increased, etc., are typical characteristics of overage.
Air conditioning. The national standard stipulates that 'life' is 12 years. In use, be careful not to switch the air conditioner frequently, because the current when the compressor starts is high, and the frequent switch is easy to burn the motor. The over-age air conditioner has more dust, blocking the air outlet and affecting heat dissipation. Jianguo suggested that air conditioning should be installed in the shade, in a ventilated place, avoid direct sunlight.
Washing machine. The service life is 10 years. Overage may cause problems such as water leakage, electric leakage, heat generation in the fuselage. Especially in high temperature weather, long-term use will increase the possibility of spontaneous combustion. Internal parts may cause electric leakage or fire.
TV. The average life of the TV is 8~10 years. When the picture on the CRT TV is not clear, the picture is shaking, it means that the related components will age and the radiation will increase; once it encounters a collision, it will suddenly cool. Heat, etc., may also cause an explosion. The size of a flat-panel TV is inevitably large, and the heat is also large. Therefore, it can be used in a dry and ventilated environment to increase its service life.
Electric water heater. The service life is 6 years. The surface of the overheated water heater heating pipe is prone to scale, which reduces the heat dissipation efficiency, and even causes the surface of the heating pipe to burst and damage, increasing the risk of electric shock; excessive heating of the electric heating pipe will increase the product. Electricity.
Lu Jianguo said that in 2008, the National Household Appliance Standardization Committee organized the relevant national standards for the safe use of household appliances, which can be referenced by consumers when purchasing.
