In CASE: 13 types of electric kettles are security risks - kettle - Hardware Industry

10 16, China Consumer Association held a news briefing to announce the some cordless electric kettle and a comparative steel radiator test results. The results showed that 13 kinds of security risks exist cordless electric kettle, 5 groups exaggerate the products of steel radiator heat dissipation.

Cordless electric kettle has become essential for small household appliances. According to the Consumers Association director of consumer guidance before Tiger Wang introduced the autumn of 2007, the Consumers Association Joint Beijing, Jiangsu, Anhui, Guangdong, 4 to the Consumer Association (Committee) in Beijing, Hefei, Guangzhou, Nanjing and other places in the electronics store, department store, supermarkets, 49 were purchased brand cordless electric kettle products as samples to test and compare. Nominal input power rating of the sample were in the 1000W to 2000W, 1.0L to 2.0L in capacity between the price from 69 yuan to 589 yuan each ranging, covering the major brands on the market. Comparison of experimental tests commissioned by the Chinese Academy of completion of home appliances.

In 49 samples, nominal Nanhai, Foshan City, Nippon Electric Co., Ltd. production DRHG-120R type samples, due to base failure, the electricity does not work.

Understand Cordless Electric Kettle is the national mandatory product certification of household appliances, commercial products have passed 3C certification. The comparative trial, involving 48 samples although the signs are marked with the 3C certification, but passed the test found that 13 samples and the 3C certification standards incompatible with the existence of security risks.

48 cordless electric kettle has energy saving effect of sample differences in the design merits. Comparison of experimental thermal efficiency from the product (also known as energy efficiency or energy efficiency), capacity, power boiling time, reset time, pour the performance of water function and other aspects of the use of performance testing and comparison. The results showed that 90% of high thermal efficiency of the sample were 85% to 95%; 48 samples were clearly visible maximum capacity scale identification, seven samples are not marked with a minimum capacity of scale or scale capacity value, the majority of The capacity of the sample with larger error scale, normal use will cause inconvenience to consumers; sample boiling time and reset power to design basic and reasonable power boiling time of 1 ~ 19 seconds are within the reset time between 2.8 seconds to 71.2 seconds. Testing also found that individual samples in the pot body and spout filter design there are irrational factors, leading to pour more water when the jar left.

Called radiator radiator is heating in winter in northern China as a commonly used building materials. Along with the gradual implementation of energy saving policies and consumer decorative radiator, the improvement of economic and other requirements, some new radiator by people of all ages. At the same time, the radiator market also appeared to reduce the number of radiator-chip configuration to achieve the so-called low-cost capacity to false and exaggerated product heat dissipation heating effect to the overcharged installation charge for a greater benefit to shirk its responsibility to serve the discount to reduce the installation standards of consumers phenomenon.

For the above, the end of 2007 to early 2008, the Consumers Association in Beijing Joint Beijing Consumer Association sold part of the field were compared with steel radiator experiment, testing commissioned by the State Building Materials Industry

Architectural Hardware Plumbing Product Quality Supervision, Inspection and Testing Center. Comparison of test results showed that the sample of 24 group radiator, there are 5 groups measured standard heat radiator is smaller than its nominal thermal capacity of more than 3%, the worst 20%.

Wang said before the Tigers to virtual product heat emission standard practice of exaggerating the effects of heat in the radiator industry is not an isolated phenomenon, and some manufacturers tamper testing report issued by testing organizations to deceive consumers and businesses; some manufacturers take unscientific reckoning, so that some products labeled with the measured heat capacity values were quite different. Improve the heat dissipation capacity, enterprises should design the internal structure of the radiator itself, starting, such as increasing the outer wall of the heat radiator area, improve air circulation Road conditions, speed up air flow and reduce the heat sink thermal resistance such as the wall. If you rely on superficial to "improve" the radiator heat dissipation, eventually be eliminated.
