1. Choice of place of purchase
Buying household gas cookers should go to professional big stores, big shopping malls and offices of various gas sales companies in various places to buy. Never buy them at the stalls or small stores, or buy "three nos" products. Don't forget to ask for a formal invoice after purchase, and save the warranty certificate and invoice, otherwise the quality problem users will be helpless.
2, the choice of gas cooker types At present, there are many kinds of domestic gas stoves on the market. According to the use of gas, there are three kinds of natural gas stoves, artificial gas stoves and liquefied petroleum gas stoves; according to the focus of the stove, there are single-eye stoves and multi-eye stoves; The installation method is divided into a desktop stove and a built-in stove; according to the ignition method, a "cast iron stove", a piezoelectric fire stove and an electronic pulse stove which are ignited by a match.
First of all, we must know the gas used in our home, whether it is natural gas (code T), artificial gas (code R) or liquefied petroleum gas (code Y). Due to differences in the nature of the three gas sources, the appliances cannot be mixed. Consumers should pay attention to the markings on the box when purchasing a domestic gas stove. At the same time, consumers can also distinguish the type of gas they are using from the model of the domestic gas stove. For example: the domestic gas stove of model JZ12T.2-A, J stands for home, Z stands for stove, 2 stands for two-eye stove, T stands for natural gas, if the letter is R for artificial gas, and if Y stands for liquefied petroleum gas. At present, most rural households use liquefied petroleum gas.
Secondly, the choice of materials and stove eyes, the current market stoves are mainly stainless steel and glass two categories. The stainless steel material is strong and wear-resistant, but the gloss of the surface will be worse when used for a long time. The glass material is beautiful, corrosion-resistant and wear-resistant, but the heat-resistance is not as good as that of stainless steel. It is relatively "squeezing" in use. If it is accidentally "encountered" after the heat, it may burst. Therefore, it is recommended to purchase products of different materials according to your own preferences. It is better to choose stainless steel from a safety point of view. There are two burning heads, three burning heads or four burning heads in the shape. The general household population is small, and it is enough to use two or three burner heads.
Third, determine the purchase of desktop or embedded stoves based on the needs of the family. The table top is a type of cooker on which the whole body is placed on the support surface, and the embedded name is to embed the main body of the cooker under the support surface. Because the built-in stove inserts the countertop into the countertop of the cabinet, it is parallel to the countertop of the cabinet. The upper bracket is movable and can be removed at any time for cleaning. After the meal, the cabinet and the gas stove top can also be cleaned together. It has the characteristics of easy cleaning, is loved by people, and more and more appears in the home and kitchen. However, if the general rural area does not carry out the overall renovation of the kitchen, it is more cost-effective to purchase a desktop cooker. In particular, consumers are reminded that, according to current national standards, embedded household gas stoves must have flameout protection safety devices, so consumers must pay attention to this when purchasing. Due to the special use conditions of the embedded gas stove, the accidental flameout phenomenon is more likely to occur during its use, and the flameout protection safety device will play a very good protection role.
Fourth, choose the ignition method. It is best to use a pulse-ignited domestic gas stove because the pulsed ignition of the domestic gas stove has a high ignition rate and no noise.
3, look at the packaging, look at the appearance
The packaging quality of domestic gas cookers reflects the quality of the products to a certain extent. Qualified cookers should be packed neatly, beautifully printed, and completely marked. The product should be marked with: product name and label, applicable gas type, gas rated pressure, heat flow, manufacturer name, production date and code number. Inferior products are often rough and simplistic in packaging. There are no signs or signs on the products that are not complete, irregular, incorrect, and no product certification.
Open the package, the appearance of the gas stove should be beautiful and generous, there is no collision phenomenon in the body. Some paints made of materials such as cast iron and steel plate should be evenly leveled without blistering or falling off. The overall structure of the gas stove should be stable and reliable, the stove surface should be smooth and flat, no obvious warpage, the installation of parts should be firm and reliable, and there should be no looseness.
The parts are processed finely, the connecting parts are firm and reliable, and the pot bracket should be stable and firm. There should be a fire eye that can adapt to the 100mm diameter pan, and it should not be deformed or damaged when putting 10kg objects. The parts of inferior cookware are rough, and some even have obvious pores and blisters on the gas path system, which not only affects the normal use of the cooker, but also easily causes personal injury accidents. Due to the indiscriminate production of the inferior cookware, the scraping of the work, the roughening of the assembly process, the parts of the cooker are loose, the parts are not matched, the valve or the knob is not flexible, the strength of the stove is not enough, the deformation of the stove is severe after the load, the body warps, etc. .
4. On-site ignition test
When purchasing a gas stove, it is necessary not only to look at the processing quality such as the appearance, but also to test the ignition. If there is no fire test condition in the store, you should test the fire in time after buying it. If it is not easy to use, it should be returned in time. In the case of fire test, the electric ignition device should be flexible and reliable. It should be fired 10 times in a row, at least 8 times, and the flame should be spread throughout the fire eye within 4 seconds without deflagration. After the burner is on fire, the position of the damper should be adjusted to make it appear blue flame. The inside and outside of the flame are distinct, there is no tempering, no dead fire, and there is basically no yellow fire. The ignition and extinguishing of the flame should be small. Otherwise, the gas is not fully burned, and the carbon monoxide exceeds the standard, which is harmful to human health.
5, 掂 component
By hand measuring the cooker, the standard-compliant product has sufficient weight due to the selection of high-quality materials. Inferior stoves are lighter in weight and lighter in weight.
