Beijing, July 31 (Xinhua) according to the website news of Guangdong provincial market supervision and Administration Bureau, the Guangdong provincial market supervision and Administration Bureau recently carried out supervision and random inspection on the quality of 100 range hood products produced by 78 enterprises. The final performance showed that 18 products produced by 17 enterprises had different standards, involving brands such as Mrs. Qiao.

According to Xiaochang, the main divergent items are as follows: \

protection for touching live parts: the protection items of 4 products touching live parts are different. The danger of electric shock is the most fatal persecution of electrical products to the travelers. Electric shock can be divided into direct electric shock and indirect electric shock. The operator can directly touch the dangerous live parts, or can touch the live parts through the opening with a little force, which will cause direct electric shock. Indirect electric shock means that although the operator will not directly touch the live parts, but can touch some insulating parts, such as the damage of such insulation parts or failure under high voltage, the operator will get electric shock.

input power and current: the input power and current terms of three products are now inconsistent. This item is now mainly to assess the actual power and nominal power of the equipment in the normal working state. If the power fault is too large, the power supply line and power supply will be overloaded when the appliance is used, and there is the risk of first fire.

leakage current and electrical strength: the items of leakage current and electrical strength of two products are different. The main assessment of this item is that under the condition of wetting, the leakage current of the appliance should not be too large, and its electrical strength should also meet the requirements. When the leakage current is too large and the electrical strength of the insulation breaks down, the user may get electric shock.

unconventional work: the items of abnormal work (excluding the test in Clause 19.11.4) of 6 products are different. The main assessment of this item now is that the appliance should be able to prevent fire and users from touching dangerous live parts and moving parts under abnormal work or misoperation. This item is different now, which can lead to fire or electric shock.

organization: the organization items of 10 products are different in this spot check. The organization involves all aspects of the product, and the product organization with reasonable design is the main guarantee for the consumer to exercise the appliance calmly. Organizational differences can lead to fire, electric shock and other dangers of life and property.

internal wiring: the internal wiring items of 1 product are different in this spot check. This item now mainly examines the wiring request, insulation request and fixing means of the internal line of the product. When the internal line contacts with sharp edges of metal, the insulation of the internal wire is easy to be damaged, which can lead to leakage of electricity and the user is in danger of electric shock.

power connection and surface flexible wire: the power connection and surface flexible line items of 11 products are identified in this spot check. This item can cause inflammation, insulation damage, fire or electric shock.

Grounding measures: the grounding measures of 5 products are different in this spot check. The grounding measure item is mainly to check whether the product's grounding protection ability meets the requirements of national standards. In case of leakage due to insulation damage, the product will not be able to select a serious grounding function, and there is a risk of electric shock.

electrical clearance, creepage distance and solid insulation: the items of electrical clearance, creepage distance and solid insulation of 7 products are different. Electrical clearance, creepage distance and solid insulation are particularly important to the electrical integrity of the appliance. If the electrical clearance and creepage distance between live parts and metal watch case are too small, the thickness of solid insulation is insufficient or the electrical performance is not up to the standard requirements, it is easy to show the product leakage when using the product, which will lead to the charging of the watch case and bring the danger of electric shock to the operator. If the electric gap and creepage distance between charged parts with different polarity are too small, it is easy to cause short circuit and cause fire hazard.

noise: the noise items of 7 products are different in this spot check. This item is now mainly used to assess the noise generated by the equipment when doing things. If the noise generated by the appliance is too high, it will cause noise pollution to the surrounding environment.

air performance (air volume, wind pressure): the air performance (air volume, wind pressure) items of the four products are different. This item mainly examines the performance of air volume and air pressure. This item has a direct impact on the smoke exhaust efficiency of range hood and can not effectively roll the lampblack.

energy efficiency level: the 12 product energy efficiency rating items are different. At present, the project mainly assesses whether the relevant indicators of energy efficiency grade, such as total pressure efficiency, standby power, shutdown power, normal odor reduction degree, etc., meet the standards and the requirements of product quality indicators. When the energy efficiency level is not satisfied with the standard requirements or false standards, it will cause more power consumption, poor smoke exhaust efficiency and mislead consumers.

As for the creators and sellers of substandard products found in the spot check, Guangdong market supervision and Administration Bureau will instruct the relevant municipal market supervision administrations to comply with the provisions of the product quality law of the people's Republic of China, temporary measures for the administration of product quality supervision and random inspection, and the relevant regulations of the State Administration of market supervision and the Guangdong Provincial Bureau of market supervision Do things after customized. The first is to order the creator to stay in production and sale, supervise the overall products, make a thorough repair of the inventory products, correct the sold products within a time limit and take the initiative to release relevant news; the second is to tell the seller to stay for sale of products of the same model; the third is to change the packaging of products to be sold again after rectification or make a mark of conformity; the fourth is the market The supervision part carries out regular follow-up and spot check on the qualified products that are allowed to be rectified; fifthly, it records the unqualified products and their creators and sellers into the reputation files of quality supervision, and implements the reputation classification supervision.
