Original Title: More than half of the spot check products are unqualified! There are hidden dangers such as electric shock, fire and other hidden dangers of electromagnetic stoves

Everyone knows that when you buy an electromagnetic cooker, you do n’t need to install it. You can buy it with it. It is small and heated quickly. There is no light fire. As long as there is an socket to get electricity, cooking and cooking hot pot anytime, anywhere, is convenient. However, the premise of all products is safety first. If you buy an electromagnetic cooker with hidden dangers, consumers do not know, which is the danger directly. The newly announced electromagnetic stove quality countries supervised and random inspections, and found that more than half of the electromagnetic stoves were unqualified, and there were hidden dangers such as electric shock and fire.

The results of the national supervision of electromagnetic stove products released by the State Administration of Market Supervision, the results of the quality of electromagnetic stove products, showed that this kitchen and bathroom electrical products involved in millions of households have outstanding quality problems.

In the testing agency that undertakes the national pumping mission, the testing staff told reporters that the electromagnetic cooker is an electrical cooking appliance made of electromagnetic induction heating principle. As a popular electrical appliances, it is the most basic safety bottom line for consumers when using products, which is the most basic safety bottom line for production companies. Therefore, in the national standards, the protection projects that touch the charged parts, the structure and shell of the electromagnetic stove products should be sufficient to prevent users from using electric shock accidents due to the touch of the electrical component when using the product.

Peng Bei, a senior engineer of the Quality Inspection Center of the Ministry of Industry and Information Technology Fifth Research Institute: If our product is unreasonable in structure or shell design, our user may touch power components during use. This It is required that our products can ensure, or the shell design can prevent the fingers from extending, or even if you (fingers) are extended in, you cannot touch the charging (ministry) part.

The test personnel introduced that strictly controlling the size of the hole on the shell and the toughness of the ventilation grille is an effective method to prevent the fingers from being stretched into the electromagnetic cooker. According to national standards, the test of this simulated manual hand indicates that it cannot be extended from the ventilation gate grid of the electromagnetic cooker; or after it is extended, it cannot touch the internal charging parts. However, during the testing agency, the reporter saw that when the inspector was tested by the electromagnetic cooker produced by this nominal named Zhongshan Hui Electric Co., Ltd., the test finger could easily reach into the ventilation grid and touched the charged parts. Essence In order to explain the harm of this situation more, the inspectors did a special experiment.

Peng Bei, a senior engineer of the Quality Inspection Center of the Ministry of Industry and Information Technology Fifth Research Institute: We use a small light bulb to simulate the human body and use experiments to finger the human fingers. We see that during the experiment, when the test refers to the stretching of the shell, we can eventually encounter a charged (section) piece. The light bulb was lit when it encountered a charged (section) piece, indicating that there was already a current in this light bulb that passed.

The reporter learned that this time, three batches of samples were found to have found problems on the protection projects that touched power components, and they were judged to be unqualified. The production enterprises are nominated as: Zhongshan Hui Electric Co., Ltd., Xiamen View Beibei Technology Co., Ltd., and Guangdong Xiangyin Intelligent Technology Co., Ltd.

The protection of the touched part of the power parts does not meet the requirements of national standards, and it may directly bring consumers to the risk of electric shock and endanger the personal safety of consumers. In further investigation, the reporter found that there is another special requirement for the electromagnetic stove, that is, once the electronic circuit fails, or the operation error occurs, it should also be ensured that the product can prevent electric shock, fire, overheating, toxic gas, etc. Dangerous. It is called non -normal work to evaluate this special requirement.

The testing staff told reporters that the electromagnetic cooker usually has a temperature controller, which is used to control the temperature during cooking; more importantly, it can also prevent the cooking of cooking food too high and cause danger of fire. However, as an electrical product, the temperature controller of the electromagnetic cooker occurs short -circuit or failure, which is the most common accident in the daily use of consumers. Therefore, the national standard stipulates that even if the temperature controller fails, the electromagnetic cooker will not exceed 270 Cairvin during the test under the normal work of the experiment.

However, the reporter saw in the testing agency that when the inspectors stipulated that in accordance with the national standards, the temperature controller was invalidated, when the triangular electromagnetic cooker produced by Guangdong Xinpinxin Electric Co., Ltd. was tested by non -normal working tests, it The temperature of the oil quickly exceeded 270 Cairvin.

Liu Qiang, technical director of the Quality Inspection Center of the Ministry of Industry and Information Technology Fifth Research Institute: Oil temperature exceeds 270k, this situation is reflected in our usual use. If the induction cooker temperature controller used by consumers’ home is invalidated, it is equivalent to equivalent to equivalent There is no temperature protection device when the induction cooker is working, which will cause it to constantly heat it. Then no matter when boiling water or cooking, or fried, there is no temperature control. The temperature of the food that may be heated has been rising and dangerous, so if it is more serious, it may cause fire.

The reporter learned that in the country’s supervision and random inspections of the quality of electromagnetic stove products, there were 9 batches of non -normal working projects. The nominal manufacturers include: Zhongshan Dajin Electronic Technology Co., Ltd. and Guangdong New Products Electrical Co., Ltd. , Zhongshan Pengou Electric Co., Ltd., Foshan Blue Ant Electric Industry Co., Ltd., etc.

The thermal efficiency items are unqualified samples for 21 batches

Unqualified work and protection of power -touched parts of power -related parts are unqualified, which seriously affects consumers’ personal safety. In further investigation, the reporter learned that the electromagnetic stove’s efficiency level is not qualified, which is directly related to the economic interests of consumers. According to the national compulsory standards “Household Electromagnetic Stove Energy Energy Limited Value and Energy Efficiency”, the energy efficiency level includes two indicators: thermal efficiency and standby state power.

The test personnel introduced that thermal efficiency is a specific quantitative indicator that transforms electrical energy into effective thermal energy. Compared with the heat efficiency of about 50%of ordinary gas stoves, the electromagnetic stove is more economical and efficient. The thermal efficiency can be as high as 80%-92%. This is also many consumers. One of the important reasons for buying an electromagnetic cooker. According to national standards, the thermal efficiency is divided into three levels. This Pentium Prince brand electromagnetic cooker produced by Laipin Electric Co., Ltd., Foshan Shunde District, is not less than the minimum level of 86%. Only 84.78%were judged as unqualified products.

抽查产品超一半不合格!你家的电磁灶安全吗?

Liang Jinchang, deputy director of the Quality Inspection Center of the Ministry of Industry and Information Technology’s Fifth Research Institute: Generally speaking, under the same conditions, products with high thermal efficiency value will be higher than that of products with lower heat efficiency. The thermal efficiency project is unqualified to mislead consumers. Consumers often spend more money, but they cannot buy an energy -saving product, which means that they have not achieved the purpose of saving costs in use.

In order to save power and economical, consumers are often willing to spend more money and buy electromagnetic stoves with high heat efficiency. However, once the thermal efficiency project of the product is unqualified, consumers spend more money, which will become unjust money. According to statistics from reporters, this time, the unqualified samples of thermal efficiency projects were 86%, and the problem samples were as many as 21 batches, accounting for 28.4%of the total samples.

Among them, the problem of electromagnetic cookers produced by Zhongshan Feiling Electric Co., Ltd. is the most serious. The real measurement value of thermal efficiency is only 79.26%, and even 80%is not available. There are two samples between 80%-81%of thermal measurement values, namely the electromagnetic cooker produced by Guangdong Xiangyin Intelligent Technology Co., Ltd., with the actual measurement value of the thermal efficiency of 80.07%; The actual measurement value of the power efficiency produced by the company is 80.20%.

The remaining heat efficiency problems are relatively serious. The nominal manufacturers are: Zhongshan Likang Electric Co., Ltd., Zhongshan Feihong Electric Co., Ltd., Foshan Shunde North Guide Electric Industry Co., Ltd., and Guangdong Rongsheng Electric Co., Ltd.

Smooth investigation found that the problem of unqualified electromagnetic compatibility is outstanding

Consumers use an electromagnetic cooker and do not happen without accidents. It is the most basic safety bottom line. In other words, the design of the structure or shell cannot be used for electric shock because of the unreasonable design of the shell. Even if it is faulty or operating errors, the danger of electric shock, fire, and overheating can not occur, but some products cannot meet these requirements at all. In addition to these security issues, this random check found that the most prominent is electromagnetic compatibility. How much is its unqualified rate?

Because of the many advantages such as ignorance, smoke -free dust, and convenient use, the electromagnetic cooker was quickly recognized by consumers and became one of the essential kitchen and bathroom appliances in many families. At present, there are nearly 200 companies producing electromagnetic stoves in my country, with an annual output of about 15 million units. Production companies are mainly concentrated in Guangdong, Fujian, Zhejiang and Jiangsu.

The reporter sorted out this time when the quality of the electromagnetic stove product quality was supervised and raised the problem project, it noticed that during the testing process, 16 security items including the protection of the electricity with power and the normal work. Work, 9 batches of the 74 batches of samples are unqualified and the unqualified discovery rate is 12%. Compared with safety projects, the problem of electromagnetic compatibility is particularly prominent.

The test personnel introduced that electromagnetic compatibility is a collective name, including multiple test items, including any unqualified one, and may cause signal interference to other surrounding electric equipment during product use. Like the interruption of washing machines encountered in many consumers in daily life, short circuits on the TV, etc., may be caused by the unqualified electromagnetic compatibility of a certain electrical appliance that is using.

The reporter learned that this time the national pumping electromagnetic compatibility detected the two indicators of continuous harassment voltage and radiation harassment. The results showed that a total of 38 batches of samples could not meet the national standard requirements on these two indicators.

Product unqualified rate exposure to the industry has some deep problems in the industry

The inspector told reporters that the product did not join the electromagnetic compatible protection circuit or electromagnetic interference inhibitory device as required, which is the main reason for the unqualified electromagnetic compatible projects.

All 40 batches of unqualified samples, 38 batches of electromagnetic compatibility are unqualified, and the market regulatory authorities believe that this result not only directly increases the unqualified rate of supervision and random inspections of the quality of the electromagnetic stove products, but also exposes the existence of the industry in the industry. Some deep problems.

Miao Yuchen, Director of the Director of the Drawn of the Division of the State Administration of Market Supervision: The market competition in the electromagnetic stove products is fierce. Some companies rely on low -cost products to impact the market, blindly reduce costs, and even have a problem of cutting corners. Or electromagnetic interference inhibitory device.

The lack of deserved accessories causes the unqualified rate of electromagnetic stove products. With the in -depth reporters of the survey, some companies disconnected the materials on the core component coil of the electromagnetic stove. It is another important factor that leads to the quality of this product.

During the survey, professionals told reporters that the thickness of the core component of the electromagnetic cooker -the thickness of the coil disc, directly affecting the energy efficiency of the electromagnetic cooker to a certain extent. In recent years, affected the market fluctuations of coil trays raw material metal copper, the price of coil discs has risen. In order to reduce costs and pursue profits, some companies have not been produced in accordance with the requirements of product design matching, and even the thickness of copper wires of the coils cannot be basically guaranteed.

抽查产品超一半不合格!你家的电磁灶安全吗?

Liang Jinchang, deputy director of the Quality Inspection Center of the Ministry of Industry and Information Technology Fifth Research Institute: Let’s compare these two electromagnetic stove products. This is a qualified product. This is an unqualified product. This product, the copper wire on its coil plate is thicker. In this case, the same power produces more calories.

The thickness of the copper wire of the coil plate directly affects the thermal efficiency of the electromagnetic cooker. In further investigation, the reporter learned that there are still many factors affecting the thermal efficiency of electromagnetic cookers. In addition to hardware facilities, the soft power of professional design is also particularly important.

抽查产品超一半不合格!你家的电磁灶安全吗?

According to professionals, some enterprises have insufficient design capabilities, which leads to the size specifications of electromagnetic coil discs that do not match the electronic control parameters. The energy conversion rate is low, and the thermal efficiency naturally does not meet the national standard requirements.

抽查产品超一半不合格!你家的电磁灶安全吗?

The reporter learned that the General Administration of Market Supervision has taken corresponding measures to deal with the problems found in the supervision and random inspections of electromagnetic stove products.

抽查产品超一半不合格!你家的电磁灶安全吗?

Miao Yuchen, Director of the Director of the Division of the Quality Supervision Department of the State Administration of Market Supervision: We have deployed the market supervision departments where the enterprise is located in accordance with the law. The seizure and seizure of unqualified products are ordered to stop the production and sales of the same product and make rectification; deploy the market supervision department of the industrial agglomeration zone to carry out special rectification of electromagnetic stove products, check the key enterprises in the jurisdiction, comprehensively use multiple regulatory methods to maintain quality (to maintain quality ( Supervision) High -pressure situation and seriously deal with quality illegal acts.

The safety problems of the electromagnetic cooker, the thermal efficiency project does not meet the standard, and the electromagnetic compatibility project that directly increases the national pumping rate of this time. In fact, these are just lesions. , Reduce costs, cut corners. When is it really removed, it is possible to remove the lesion. It is also important. The electromagnetic stove is the first batch of home appliances to implement compulsory product certification in my country. Consumers must confirm whether there are 3C certification signs before buying.
