A humidifier is a household appliance that increases the humidity of a room. The humidifier can humidify the designated room or it can be connected to a boiler or central air conditioning system to humidify the entire building. The humidifier is divided into two types: a fan humidifier and an ultrasonic humidifier. When purchasing a humidifier, it is best to use an ultrasonic humidifier, and do not place it near the bedside or near the sofa to reduce the water. The fog breeds bacteria and harms the human body.
The Guangdong Provincial Bureau of Quality and Technical Supervision sampled 30 batches of humidifier products produced by 26 companies in Guangdong Province. After inspection, it was found that 7 batches of products produced by 7 companies were unqualified, and the rate of unqualified products was 23.3%. Only 3 batches were rejected, and the product quality was found to be 13.3%. The unqualified items involve four items: signs and instructions, protection against contact with live parts, mechanical strength, and structure.
This spot check is based on GB 4706.1-2005 "Safety of Household and Similar Electrical Appliances Part 1: General Requirements", GB 4706.48-2009 "Special Requirements for Safety Humidifiers for Household and Similar Electrical Appliances", Relevant Laws Regulations, departmental rules and regulations, current and effective corporate standards and product quality requirements. Marking and description of humidifier products, protection against contact with live parts, input power and current, heat generation, leakage current and electrical strength at operating temperature, moisture resistance, leakage current and electrical strength, abnormal operation, stability and mechanical Hazardous, mechanical strength, construction, internal wiring, power connections and external cords, external conductor terminals, grounding measures, screws and connections, clearances, creepage distances and solid insulation were examined.
Uneven quality, release of harmful substances
At present, the humidifiers sold on the market range from tens of yuan to several hundred yuan. Internet search, cheaper for four or fifty yuan, expensive for two or three hundred yuan, and more high-end and so on. The price difference is so large, and the quality is naturally uneven. Poor quality humidifiers may release harmful substances while releasing water mist, and there may be hidden dangers such as electric leakage during use.
Humidifier needs to be cleaned regularly
If the humidifier is used for a long time, the inner wall will breed fungi or bacteria. Some of the pathogenic bacteria will enter the body's respiratory tract and lungs through tiny droplets of water, which may cause allergic reactions, fever, and even pneumonia. It is best to keep changing the water every day and wash it thoroughly every two weeks. Especially the humidifier that has just been activated must be cleaned.
Xiao Bian advises everyone, it is best not to use the humidifier for a long time to avoid indoor humidity rise. Moreover, staying in the air-conditioned room for a long time, long-term air conditioning has certain disadvantages to our body, it will make our skin dry and reduce the resistance, especially at night, or sweating all over the body. At the time, Xiao Bian suggested that you should not open the air conditioner.
