When purchasing household appliances, we should pay attention to the production information of the heater and be careful of hidden dangers.

Electric heater is one of the main supplies for people to resist cold in winter. Now there are many kinds of electric heaters on the market, such as electric oil tins, heaters, electric heating wires, quartz tubes, fast heating furnaces and so on. The prices vary from tens of yuan to thousands of yuan. In order to help customers know the product quality and product information of electric heaters, guide customers to choose and use electric heaters rationally and scientifically. On September 27, Chongqing Consumer Committee conducted a comparative test on some brand indoor heaters (electric heaters) sold in Chongqing market. It is found that the more expensive the heater is, the better. Customers should pay attention to selling the heater only if it is not expensive.

Electric oiling, heater, electric heating wire... There are 20 kinds of household heaters tested, which have potential safety hazards.

The cheapest sample is only 49 yuan.

According to Xu Jing, Secretary-General of the Consumer Committee, the samples of this comparative experiment were purchased randomly by the staff of the Committee as ordinary customers in shopping malls and large supermarkets in the main urban area of the city. A total of 20 sample heaters of 8 brands were purchased, including 3 radiation heaters, 4 convection heaters, 6 wind heaters, 7 oil tins heaters, and 20 samples touched 8 brands such as Emmett, Mei, Avant-Forward and Matsuhashi.

The prices of these 20 samples are quite different. The price of the highest brand is 1199 yuan, and the lowest is 49 yuan for the heater.

This comparative test entrusted to Weikai Testing Technology Co., Ltd. for testing, mainly aiming at 14 items of safety and comfort that customers concerned about, and using innovative test methods to evaluate the influence of electric heater on room humidity and the intellectualization of electric heater.

Electric oiling, heater, electric heating wire... There are 20 kinds of household heaters tested, which have potential safety hazards.

Unsatisfactory safety performance

In the target test of safety performance for 20 samples, 17 samples have reached the standard, and 3 samples have potential safety hazards in varying degrees. Meanwhile, the logo and clarification show that the brand of Songqiao is defective. In this test, there are defects in the logo and elucidation of Songqiao Brand. The samples are Class II appliances (plugs are two pins, no grounding pins), but the product specifications are not marked.

In the protective test items for touching live components, the "Songqiao" brand has potential safety hazards. The inner connecting wire of the sample contacts directly with the metal shell (the metal shell is not grounded). The B-type test bar can touch the inner connecting wire indirectly by touching the metal shell. Under extreme conditions (such as the surface insulation damage of the inner connecting wire), it is very easy to form electric shock, so there are potential safety hazards.

Input power and current are null and void

The nominal input power (or current) of the products produced by electric heaters reflects their "heating" ability. The higher the nominal power, the better the heating effect, and of course the power consumption will increase.

In the 20 samples tested, no power falsification was found. In the abnormal test items, the overall performance is better. Among the 20 samples, protective measures such as anti-dumping switch (active blocking of power supply immediately after the electric heater is dumped) and overheating protection device (active disconnection of power supply immediately after the temperature is too high) are installed, which all meet the requirements of the specifications.

In addition, the structural design of 20 samples can satisfy the requirements of specifications, conform to the concept of safety design, and ensure the safe use of customers.
