The quality of the kitchen mainly depends on the gas stove, and the misunderstanding should be avoided when purchasing the gas stove.

Kitchen reform needs to start with gas stoves to avoid misunderstandings and avoid potential risks.

"The quality of the kitchen mainly depends on the gas stove." Xu Jinbin, director of the kitchen electric department of Gome Store, said that the public knows a lot about large household appliances such as color TV sets, refrigerators and air conditioners, but little about gas stoves. They think it's enough to buy one at random and go home. In this way, they often find that there is either insufficient energy, or there is no automatic flameout device, which has potential safety hazards, or because of insufficient combustion, too fast use of gas, and so on, which is a lot of trouble. Therefore, it is necessary to know some common sense and avoid some misunderstandings before buying a gas stove.

Types and functions are constantly updated.

According to Li Huizhen, deputy director of brand management department of Wanhe Group, gas stoves have a history of 30 years. In the early days, the gas stove for burning bottled liquefied gas was made of cast iron, thick and heavy, and there was no electronic ignition device, so it could only be ignited with matches. After 1980, various foreign gas cookers entered China one after another, and the number of domestic gas appliance enterprises surged, and the types and functions of gas products were constantly updated. After 1990, the material of gas cooker basically eliminated cast iron, and manual ignition was completely replaced by electronic ignition. Tempered glass panels, ceramic panels and stainless steel panels appear one after another, which are light and beautiful, and the thermal efficiency is greatly improved.

In recent years, the collocation of gas stoves, range hoods and cabinets has become an important aspect of family decoration, and the appearance of gas stoves has become more and more furniture. There are both desktop and embedded cookers, which are subdivided into gas, liquefied gas and natural gas cookers, as well as combined cookers and electrical appliances. In terms of safety, there are air leakage alarm devices, oil temperature overheating protection devices and dry burning prevention protection devices.

New stoves compete for energy saving and high efficiency.

"Don't be confused by the concept when buying a cooker. In fact, the most important thing about gas stoves is nothing more than two points: one is to be big, and the other is to save energy. " Li Tao, manager of the brand management department of Wan Jiale, said that many businesses now promote many concepts such as three-ring fire, four-ring fire and how to get air, but consumers only need to know a few key indicators. First, whether the thermal efficiency reaches more than 50%, and second, whether the heat flow reaches more than 3.8KW.

According to Li Tao, the "Double High Fire Pioneer" series cookers mainly promoted by Wan Jiale take large firepower and high thermal efficiency as the market selling points. By increasing the flame area at the bottom of the pot and prolonging the residence time of the flame at the bottom of the pot, the heat absorption at the bottom of the pot is greatly improved, the thermal efficiency is increased by 10 percentage point compared with the national standard of 50%, and the firepower is increased by more than 20% compared with the common gas stove. Wanhe Li Huizhen said that the series of internal combustion stoves launched by Wanhe last year adopted innovative internal combustion technology, which made the thermal efficiency reach 63%, saving a quarter of the gas compared with stoves meeting national standards.

The shopping guide of Suning Appliance Store told the reporter that in 2008, many cookers were emphasizing the adoption of "headwind" new technology. "In the past, the flame was sprayed out, and people who cooked often felt hot in their stomachs. The upper wind makes the combustion process complete above the panel, and the abdomen will never be hot again. " Wan He and Li Huizhen said:

In addition, the traditional cookware emphasizes the functional design and ignores the appearance design, while the new cookware in 2008 strengthened the appearance design. Wan Jiale's Li Tao said that in 2008, Wan Jiale's new gas stove used an oversized stainless steel flat plate with rolled edges. The surface is sandblasted without fingerprints, and the waterproof board is integrated with the panel, which is simple, waterproof and not greasy.

Five steps to choose a gas stove

First of all, know whether your household gas is natural gas, artificial gas or liquefied petroleum gas. Pay attention to the express delivery on the box when buying, and you can also distinguish it from its model. For example, the model is JZ 12T2-A gas cooker, where J stands for household use, Z stands for cooker, 2 stands for two-eye cooker, and T stands for natural gas. If the letter R stands for artificial gas, Y stands for liquefied petroleum gas.

Secondly, you should know whether to take the flameout protection device. The cooker with flameout protection device is safer. When the flame is extinguished by wind or water, the gas can be automatically cut off.

Third, look at the surface panel of the cooker, stainless steel panel is the best. The panel should have a certain thickness, and some stoves are thin and easy to deform. Some products made of cast iron, steel plate and other materials should be painted evenly, without foaming or falling off.

Fourth, the installation position of the switch knob, nozzle and ignition device of the gas stove must be accurate. During ventilation and ignition, ensure that the gas can be ignited every time, and the flame should burn all the fire holes within 4 seconds after ignition. When the electronic igniter is used to ignite, the human body will not feel electric shock when it touches the metal part of the furnace body.

If, after debugging, the stove still has the phenomenon that all or part of the flame leaves from the burner hole, the flame burns inside the burner, and the flame turns yellow, it shows that the stove has quality problems.

Fifth, look at the throttle adjustment. During the ignition test, you should also check whether the air door of the gas stove is easy to adjust and whether the pot bracket is installed correctly.
