Household gas cookers use civil ancillary appliances such as liquefied petroleum gas and natural gas. The working principle is that combustible gas and air are mixed and burned to produce heat. At the same time, carbon monoxide, nitrogen oxides and other toxic and harmful substances are emitted during combustion. Exhaust gas. Because the combustible gas is used as the fuel, and the combustion process is a chemical reaction, and there is exhaust gas, the quality of the product is directly related to the safety of life and property. The product has been implemented for industrial production license management.
In 2016, according to the unified deployment of the Provincial Quality Supervision Bureau, the Quality Inspection Science Research Institute of Zhejiang Province and the Quality Supervision and Inspection Institute of Zhangzhou City jointly undertake the quality comparison of domestic gas cooker products. After a four-month purchase, sampling, testing and analysis, the province's 2016 domestic gas stove product quality comparison finally has a result.
This quality comparison is based on the special supervision and spot check, that is, the product meets the current product implementation standard GB 16410-2007 "Household Gas Cooker", and then the quality comparison. The quality comparison implementation process is carried out in strict accordance with the procedures and programs prescribed by the provincial bureau.
In order to accurately and objectively evaluate the problems of the quality of domestic gas cookers in our province, and to find the gaps or advantages in the quality of domestic gas cookers in and outside the province, we combine the source of different sample fields in the physical market and the network market, and mainstream in Jingdong and Suning. The e-commerce platform purchased 20 batches of different specifications and price products produced by 20 enterprises (including 10 outside the province). The lowest price of the products in the province was 1399 yuan, and the highest price was 2990 yuan. 900 yuan, the highest price is 2559 yuan. The 20 batches of the sample will be purchased together with 25 batches of products in 25 Zhejiang production enterprises. A total of 45 batches of products will have thermal efficiency, minimum heat load, heat load accuracy and durability of electric ignition device. The project is compared.
The results of the quality comparison show that the overall quality of domestic gas cookers in our province is good, and it is leading in some performances and indicators compared with well-known brands outside the province and even international big brands.
First, the thermal efficiency index of Zhejiang products is excellent, especially for the enterprises that buy samples, the average thermal efficiency value is 2.1 percentage points higher than that of the provincial products. According to GB 30720-2014 "Household Gas Cooker Energy Efficiency Limit Value and Energy Efficiency Rating", 4 percentage points is the first grade difference. Second, the requirements for the minimum heat load of Zhejiang products are also relatively high, and the average value is 20.6% lower than that of the provincial products (the heat load value should be small), and the advantages are obvious. It shows that enterprises in Zhejiang Province are closer to the needs of consumers, although national standards do not have this requirement. Third, most manufacturers have been able to adjust the heat load accuracy to a relatively controllable range. Fourth, all samples can meet the requirements of 200,000 times of durability. Its high pressure output is also >12kW. The conventional durability of the igniter has far exceeded the national standard requirements (the national standard only requires 15,000 times of durability).
Household gas cookers are indispensable products in people's daily life. In the face of a wide range of products on the market, consumers should pay attention to the following matters when purchasing:
1. Determine the type of gas in your domestic gas cooker. China's gas types are divided into three categories: liquefied petroleum gas, natural gas and artificial gas. Due to geographical restrictions, the cooker is designed according to different gas types. Do not use a cooker that does not match the type of gas used. Otherwise, it will not be used, and it will cause danger.
2. With the development of the times, the styles of gas cookers have also appeared in various patterns. Currently, the products on the market include desktop gas stoves, embedded gas stoves and integrated gas stoves. Users can follow their own kitchen decoration standards and individuals. Like to choose. Under normal circumstances, simple kitchen or short-term use, you can buy a lower-priced desktop gas stove; pay attention to the overall decoration style of the kitchen should choose embedded gas stove; consumers who pay attention to smoke exhaustion and hope to save energy in the kitchen space can choose integrated Gas stoves.
3, according to their own living habits and family members to determine the purchase of different heat load value of the domestic gas cooker, the usual dining habits Chinese cooking requires the use of firepower is relatively fierce (designed heat load) gas cooker.
4. Identification of the non-extinguishing protection device for the stove: The flameout protection device is generally a steel induction needle, which is generally installed near the flame of the small fire cover, and is opposite to the fire igniter (white).
5. When using more sharp-bottomed pots daily, you should choose a product with a smaller inner fire cover.
6. The household gas cooker implements the production license system. When the consumer purchases, first check whether the product is marked with the production license number. The correct production license number for domestic gas cooker products should be in the format of XK21-007-00XXX. Detailed product production license information can be found on the Government Administration Network of the General Administration of Quality Supervision, Inspection and Quarantine at http:// .cn/search/gyxkz/
7. Special attention should be paid to companies that deliberately conceal the name of the manufacturer, or that they are ambiguous, or who intentionally write the name of the manufacturer or the production base, because most of these companies are OEMs. Or they are small in scale, and the quality of these companies is generally poor.
8. Use and maintenance: Please read the instructions carefully before use, connect the rubber hose or metal hose that meets the standard requirements as required. When using the rubber hose, the clamp must be installed at the two joints. Then adjust the damper so that the flame when the stove is burning is blue, clear and flameless, and the phenomenon of fire is removed, and it must be re-adjusted after each cleaning and disassembly. It should be cleaned in time after use, and the deposited dirt may cause the furnace cover to be clogged, causing red fire, which may cause burn hazard due to excessive surface temperature of the cooktop. Special attention should be paid to the fact that the rubber hose has a service life of 18 months and must be replaced in time. The accidents caused by the failure to replace it in time are too numerous to mention.
