How to buy cookers?

Cookers can be said to be closely related to our lives, then, for long-term users of cookers, how can we choose a good cooker? Here are a few common sense of buying cookers for your reference.

The types of gas stoves should be suitable for local gas sources. It is necessary to know the type of gas used in your home, whether it is natural gas, artificial gas or liquefied petroleum gas. The calorific value and gas pressure of these three kinds of gases are different. If the type of stove does not match the gas, it may be dangerous, so. Never mix stoves for different gas sources. Before choosing stoves, the types of gas used should be clear. When choosing and purchasing domestic gas stoves, customers should pay attention to what kind of gas is indicated on the packing box, and they can also distinguish the type of gas from the type of domestic gas stoves. For example, model JZ-2T-A household gas stove, J for household gas stove, Z for stove, 2 for binocular stove, T for natural gas. If the letter R is for artificial gas, Y is for liquefied petroleum gas.
It is very important that the packaging and logo should be complete. If it is a "three-nothing" product, don't buy it easily, otherwise it will endanger your personal safety. Generally speaking, the packing should be marked with factory name, site and model, and each cooker should have a certificate. Instructions for use, the side panel of the cooker should have a nameplate (that is, product trademark), and the nameplate should also be marked with the name of the factory, model, applicable to gas and pressure, heat flow and production date.
Appropriate heat flow and good gas tightness heat flow: The larger the heat flow value of domestic gas cooker design, the stronger the heating capacity, that is, the more fierce the fire is usually said. However, in fact, the size of heat flow should be in line with cooking methods and cookers. If only large heat flow is pursued, the thermal efficiency of cookers will be greatly reduced, and the emission of waste gas will be increased. Air tightness: If the gas tightness of the stoves purchased and used is not up to standard, it is the greatest hidden danger of causing safety accidents. Here we introduce a simple detection method: connect the air source, close the knob, brush the plastic pipes, valve body and interface piece with soap liquid, if there is no gas leakage, it shows that the air tightness is good and can be purchased at ease.
Body Quality and Ignition Switch Body Quality Selection: Gas stove appearance should be beautiful and generous, there is no collision around the body, press the table with hand. There should be no obvious warping; the stove should be twisted back and forth diagonally with the hand, and the stove should not be deformed. The panel material of the stove should not use tinplate (magnet adsorption can be used to distinguish whether tinplate or stainless steel material); some products made of cast iron, steel plate and other materials should be sprayed evenly and smoothly without foaming or falling off. Elephant. The overall structure of the gas stove should be stable and reliable. The stove surface should be smooth and smooth without obvious warping. The installation of parts should be firm and reliable, and there should be no loosening phenomenon. The stove head and cover of the stove should be carefully processed without obvious burrs. Ignition switch: The position of ignition switch, i.e. opening (0N) and closing (OFF) and the position of large and small fires (usually with pattern marks), should be clearly and accurately marked; when igniting with electronic ignition switch, the sound should be clear and strong. If the sound of fire is soft and muffled, it is likely to be a fake and inferior product. Generally qualified stove ignition switch has a continuous service life of more than 6000 times, and the cock tightness is still qualified; and the number of inferior product igniters is less than 2000 times. Generally speaking, if a qualified product is ignited 10 times continuously, the number of ignition should not be less than 8 times, and all fire holes should be burned in 4 seconds.
Flame burning state is an important manifestation of the burning quality of stoves. Generally speaking, the external flame should be light blue when burning. Sometimes it may be orange-red, which indicates that there is impurity or a small amount of air in the gas, but it does not affect normal use. After ignition, adjust the flame size control button, large and small fires should have obvious layers and stable combustion. Even if the valve is adjusted to a minimum state or closed down, it should still be able to burn normally without jumping, extinguishing or tempering.
Generally speaking, the service life of good gas cookers is 5-10 years (according to the relevant regulations of the state, that is, standard fires are not less than 5000 times), while the service life of inferior gas cookers is only 1-2 years, and it will cause unsafe personal casualties in the use process. In addition, because the gas quality of different regions is different, especially the artificial gas, the difference is large, therefore. When purchasing gas cookers, consumers should choose gas cookers that are tested and approved by the local quality inspection department and are suitable for local use of gas sources.
