Heating appliances hidden dangers

The continuous drop in air temperature, heating small appliances has become a hot spot for public attention, but because it is not included in the scope of national energy efficiency management, security, hidden problems, poor service and other issues, often let consumers feel that "warm up not warm heart."

On the one hand, Foshan citizens face the rigid demand for heating in winter. On the one hand, they have concerns about the safety performance and energy consumption of heating appliances. How to choose a suitable heating appliance? Experts remind that local heating and whole-house heating should choose different electric heaters. In the face of all kinds of electric heaters, don’t blindly believe that the business’s publicity gimmicks should be “a look at two touches, three touches and four pressures” when purchasing. , to ensure the quality of clearance through the use of safety before shooting. In addition, you should also pay attention to safety issues when using it.

Market: Citizens willing to use heating appliances in winter

The reporter saw in the shop of Suning Zumiao that there were not many customers in the area of ​​heaters. The shopping guide told reporters that due to continuous rain for two weeks, the wardrobe-type clothes dryer is very popular, it can not only dry clothes, but also when the clothes do not dry out of the heating machine alone out of the local heating .

In several large supermarkets in Foshan, most of these dryers and electric heaters are placed in the same area. The reporter saw in the shop of Suning Zumiao that the style of the heater was dazzling, round and square, and of different sizes. Some look like a small flat-screen TV, a small one like a fan, some like a tower fan, and some like a small wall-mounted air conditioner. According to the purchase guide, there are several basic types of heaters, mainly fan-type (commonly known as the small sun), as well as vertical and tower-type infrared, quartz tube, PTC ceramic heating, and foot warmer, these All suitable for partial heating. As a whole, there are oil radiators, Euro-style heaters, and heaters. Relevant person in charge of Foshan Suning introduced the store has Pioneer, Midea, Emmett, Songqiao and other brands of six or seven series of products for the public to choose from, prices ranging from 99 yuan to thousands of dollars.

“Last year this time last year, it was able to sell more than 200 units. At present, it will have a maximum of several dozen units. It will only wait until the temperature drops again. The electric heaters can be sold hot.” ​​Gome Store shopping guide said that the temperature in Foshan this year is not too low, electricity The sales of heaters are obviously inferior to last year, and only electric heaters with partial heating so far have been more popular.

Select heating appliances: focus on safety and energy conservation

Suning Appliance pioneer counter shopping guide Mr. Chen said that for the general insulation of the consumer room conditions, the choice of heaters, heaters and other local heating heating appliances; and better insulation conditions, you can choose oil Ting, cooling air conditioning. If you want to choose a heater for use in the bathroom, you should ask the shopping guide when purchasing, or you can check the logo on the heater. Many electric heaters are now designed with a waterproof function that can be used for both indoor and bathroom use. Usually there will be signs on the body of the heater, and the waterproof performance can be used in the bathroom above "IPX2". If you pay special attention to safety, you can choose to label "IPX4" and the waterproof function is stronger.

Suning Life Electric Supervision introduced that "energy saving and health" are the two major selling points of heating appliances this winter. This year's green health products are favored. For example, oil hydrants with humidifiers, Xiao Sun with infrared health function, heaters with air filter function added, etc. For heating and air-conditioning products, sterilization, air purification and other long-term essential health functions of air-conditioning, and with the continuous improvement of heating effect and energy-saving technology, frequency conversion energy-saving air-conditioning in the winter to become the mainstream of air-conditioning consumption.

Reminder: A look at two touch three mention four pressure

Heating appliances generally consume more power, and energy-efficient heating and energy-saving products have become the hottest choice for home appliances in winter. However, since the heating appliances are not included in the scope of national energy efficiency management, the energy consumption of the products cannot be intuitively displayed in the “energy-efficiency label”, and consumers are often confused when purchasing.

At present, the varieties and styles of small household electrical appliances on the market can be described as dazzling, but the quality of products varies greatly. Because of the low threshold of electric heater technology, many small workshop-style local small enterprises also produce electric heaters, making the quality of electric heaters on the market frequent. Three non-products, fake and shoddy products have appeared on the market. Consumers should select products that have passed the national mandatory 3C certification and have clear signs. The after-sales service of the heater is particularly important, it is recommended to choose to buy in a large appliance store to reduce maintenance and other after-sales service in the worries.

Heater safety aspects are more common:

One is that the cross-sectional area of ​​the power wire is too low to meet the requirements of current carrying capacity. In use, it is easily overheated and damaged, causing an accident.

The second is that the grounding measures do not meet the standard requirements. Once the insulation fails, the metal parts will become live and cause electric shock. According to an electrical maintenance personnel, some heaters with poor quality can cause the heating tubes to burn black under unstable voltage conditions. He took care of a lot of heaters. The problem was that the heaters or fuses and switches were burned.

For halogen heaters and fluorescent tube heaters, the light is particularly bright when turned on, often with poor safety performance. Due to the relatively poor material used, the high brightness and heat energy tends to be small, and it is easy to burn the wire and cause accidents.

The electric oil tar that is considered relatively safe is also played by people. According to industry sources, some low-cost oil heaters electric heating business, in order to reduce costs, the internal connection for the ordinary wire, the shell steel plate using ordinary steel, no thermal protection device, internal parts shoddy, and some Even reduce the number of fever.

For the best overall oil cooling effect in winter, Pioneer promoter Chen Qiliang taught Foshan citizens to buy “cheats” in four articles. That is, four actions were performed when they were purchased: one to two touches, three to four presses.

The first is to see if the appearance of the style is appropriate, intuitive quality problems;

The second is to touch the hand, and whether the two sides are “double-wrapped”, it is not easy for the double-edged oil to leak. Touching the tubing, the crude tubing is loaded with more oil, heat is faster, it is not easy to dry, and the fine natural heat is slow and easy to dry.

The third is the use of hand-held, the same piece of weight is good, light is likely to cut corners.

The fourth is pressure. Just sit there and try to be sure. If the connection between the chip and the chip is not strong, there is a safety hazard in such a heater, and care must be taken when purchasing it.

Tips: improper use of heaters will bring hidden dangers

Sky Blue Electric shopping guide reminds the public that the purchase of safe and quality-safe electric heaters does not mean absolute safety. Improper use can also bring about unsafe problems. In particular, pay attention to the following four items:

First of all, the power supply of the heater must use a qualified, three-hole socket with a ground wire, otherwise there will be danger of leakage. The electric heater has a large power and should not be used together with high-power electrical appliances, electric welding machines, impact drills, etc., otherwise it is easy to damage the electric heater and cause accidents. In addition, the socket cannot be located directly above the heater to prevent the heat from rising and burning the power supply. When there is no one in the room, be sure to unplug the heater.

Secondly, in the installation and placement position, the heater should be placed in a place that is not easy to touch, away from combustibles, and the back should be about 20 cm from the wall. If you put your electric heater in the bathroom for heating, you should be especially careful. When using a water heater with a waterproof function, if the power outlet is in the bathroom, there is still a safety hazard. It is best to place the power outlet outside the bathroom. The wires of the heater should be protected by insulating rubber, and the connection with the body can be 100% waterproof. To prevent the power supply from water causing adverse consequences. The place where the heater is placed is preferably in a place conducive to air circulation and heat dissipation, so that the heater can perform a good heating effect.

Third, the electric heater cannot cover articles. The temperature of the surface of the heater is high. Once covered, the heat cannot be dissipated in time, causing burning and causing fire. In addition, it may cause the heat transfer oil inside the heater housing to increase in pressure, causing leakage of hot oil and cracking of the casing.

Fourth, when the heater is working, the surface temperature is high and the indoor air becomes dry. If it is used improperly, it can cause people to breathe poorly or cause harm to the skin. So don't stick to the electric heater. Don't put your hands and feet on the heat sink. It's very easy to burn. You don't want to blow the heater directly to your body, it's easy to burn the skin.
