What are the tips for choosing a gas stove?

Be clear about what gas to use. The types of gas can be selected are artificial gas, natural gas, liquefied gas and liquefied gas mixed with air, etc., and different gas stoves should be used for different gases. The choice of burner material.

At present, the gas stove on the market is mainly made of stainless steel, cast iron and copper forging materials, and the purchase of the gas stove head mainly depends on the material and thickness of the stove head. Selection of cooktop materials. There are two kinds of mainstream cooktop materials: stainless steel and tempered glass, and the stainless steel cooktop material is strong, has good finish and beautiful shape; The disadvantage is that the surface finish will be worse after long-term use, and the stains are difficult to clean; The tempered glass panel has good physical properties such as high temperature resistance, stamping resistance, and scratch resistance, and the appearance is delicate and transparent, and it is extremely convenient to clean.

Check the combustion quality. The inspection of the combustion quality of the gas stove must see the switch knob, nozzle and ignition device installation position of the gas stove, the ventilation ignition test should ensure that the flame can be ignited at least 8 times when starting 10 times, the flame should be burned all over the fire hole within 4 seconds after ignition, the ignition is used for ignition, the flame burns evenly and stably blue, there is no yellow fire and red fire, and there is no electric shock when the human body touches the metal parts of the stove body. Inferior gas stoves are generally accompanied by de-ignition (the phenomenon that the flame leaves all or part of the burner fire hole), tempering (the phenomenon that the flame burns inside the burner) and the phenomenon of flame yellowing during commissioning.

There are four main air intake modes of gas stoves on the market: upper air intake, lower air intake, side air intake and full air intake. Lower air type: this kind of stove is copied from the imported stove, in order to meet the cooking habits of the Chinese people to increase the heat load and burner, this kind of foreign products are required to open the cabinet, or rely on a larger cabinet gap to supplement the secondary air required for combustion, and at the same time used for the inevitable discharge of leakage gas during ignition, and small heat load design.

However, few domestic users know that the cabinet is opened, which causes insufficient combustion, high concentration of yellow flame and carbon monoxide, and once the gas leakage is large, it may cause ignition and ignition, resulting in the bursting of the glass panel. Upward air intake: This cooktop improves on the shortcomings of the first cooktop, raising the burner head above the countertop, hoping to get air through the gap between the burner head and the liquid tray.

However, during combustion, a high temperature zone has been formed in this part, and the cold air expands and rises by heating, so it cannot enter the furnace head, so the secondary air is still not effectively replenished, and the problem of high concentration of yellow flame and carbon monoxide cannot be solved fundamentally. This kind of structural design, the heat load can not be designed too large, more than 3 06 kilowatt hours of yellow flame is very powerful, the thermal efficiency is low, not quite in line with the needs of the Chinese people for fierce fire, and the high stove head makes the appearance of the stove greatly reduced, but can reduce the burst rate of the glass panel. <>

Gas stoves refer to kitchen utensils that are heated by direct fire with gaseous fuels such as liquefied petroleum gas (liquid), artificial gas, and natural gas. Gas stoves, also known as stoves, are known to everyone about their popularity, but it is difficult to see a common concept.

According to the gas source, gas stoves are mainly divided into liquefied gas stoves, gas stoves, and natural gas stoves. According to the eye of the stove, it is divided into single foci, double foci and multi-eye foci. Initial stage (before 1980):

The product structure is simple and the function is single. Before the 80s of the 20 th century, the development of China's gas industry was still relatively backward, the popularity of urban gas was very low, only a dozen percent, and almost no one in the vast rural areas used gas. At that time, the gas stove was in its infancy, and the product structure was simple and the function was single.

Previously, each gas appliance had only the simplest gas stove, and the product structure was also very simple. Most of the cooktop materials are cast iron, surface plating or spraying, etc., there is no electric ignition device, and the process is also in a relatively primitive state. Development stage (1980-1990):

Durability and reliability are greatly improved. After 1980, with the deepening of reform and opening up, the rise of the market economy, all kinds of foreign gas appliances have entered China, gas appliances production enterprises have increased from the original more than ten to nearly hundred, the type of enterprises has also developed from the original single gas company to state-owned, collective, private and other types of enterprises, foreign famous gas appliance manufacturers have also begun to look for partners in China, so that the quality and appearance of gas appliances have also fundamentally changed. The variety and functionality of products are also constantly changing. During this time, the panels, combustion system, ignition device were also improved.

The panel material is sprayed with cold plate, the burner has a cast iron stove head, surface electroplating or zinc spraying, and the ignition device adopts piezoelectric electronic ignition, which improves the ignition rate and improves the durability and reliability of the gas stove. Breakthrough stage (1990 2006): more varieties and complete styles.

Since 1990, China's and the world's economy have entered a stage of rapid development. China's gas and gas appliance business has entered a period of rapid growth. The introduction of foreign advanced gas appliance development and manufacturing technology has brought about a breakthrough change in China's gas appliance industry.

The variety of household gas cookers has increased, the styles are novel, the safety measures have been enhanced, and the materials, functions and performance have been improved. It has also improved in terms of production quality and reliability, process level, degree of automation and intelligence, advanced performance indicators, energy saving and environmental protection, and safe use. The material of the cooktop has essentially eliminated cast iron.

Stainless steel panels, non-stick oil coating materials sprayed on the surface, tempered glass panels, etc. occupy an important position in the cooker, and ceramic panels are also unique.

Gas stove is one of the kitchen appliances we commonly use, and gas stove also involves some safety issues, such as natural gas and fire, etc., so when choosing a gas stove, people are usually cautious, we need to choose carefully, to prevent the purchase of poor quality gas stove and bring hidden dangers to our safety, so what are the purchase skills of gas stove? Next, let's go and check it out!

1. The firepower is not large.

Usually when choosing a gas stove, the most intuitive criterion is that the firepower is not large, now the national standard is the rated heat flow rate (heat generated per unit of time), the double eye stove must have a stove eye to reach, now the market can basically reach and above, when purchasing, it is recommended that the general family, do not have to pursue the maximization of firepower, because the technical level of the general people's stir-fry is not easy to control a lot of fire, stir-fry is easy to paste, produce carcinogenic ingredients, The firepower can meet the cooking needs of most families.

2. Security is not safe.

When purchasing a gas stove, we should also pay attention to the safety of the stool macro of the gas stove, if the combustion stops unexpectedly, whether there is a flame-out protection function, which can automatically cut off the gas source at the first time, so as to protect the safety of use, leakage to prevent accidents, this aspect of the safety issue is very important, of course, the shorter the time for the flame-out protection device to produce the effect, the better the performance, the stronger the accident protection.

3. Save gas or not.

I believe we all know that the bottom of the pot will turn black after one year of use, which is caused by incomplete combustion, so when purchasing, the higher the thermal efficiency of the gas stove, the better, relatively speaking, it is more gas-saving and time-saving, and usually the size of the thermal efficiency will be introduced in detail on the gas stove.

Conclusion: The above content is about what are the purchase skills of gas stoves? I hope it can help you. I believe that after passing the above content, you will have a better understanding of the purchase skills of gas stoves, and if you need it in the future, you can refer to it.
