1. The choice of purchase location
When buying cassette stoves, you should go to professional big stores, big shopping malls and the offices of various sales companies in various places to buy. Never buy at a street or small shop for convenience or cheap price, let alone buy "three nos" products. Don't forget to ask for a formal invoice after purchase, and keep the warranty certificate and invoice, otherwise the user will be at a loss for quality problems.
2. Look at the packaging, look at the appearance
The packaging of the cassette furnace reflects the quality of the product to a certain extent. Qualified cassette furnaces should be neatly packaged, beautifully printed, and complete with signs.
Open the package, the cassette furnace should have a beautiful appearance, no collisions everywhere in the body, and the surface of the product should be evenly painted without blistering or falling off. The overall structure of the cassette stove should be stable and reliable, the stove surface should be smooth and flat, without obvious warping, and the installation of parts and components should be firm and reliable, and there should be no looseness.
The parts are processed finely, the connection part is firm and reliable, the pot holder should be stable and firm, the parts of the inferior cassette furnace are rough, and some even have obvious pores and sand holes on the gas system, which not only affects the normal use of the cooker but also makes it easy to use. Cause a personal injury accident. Due to the inferior cassette stove manufacturer's shoddy manufacture, cutting corners, and original rough assembly process, the stove parts are loose, the parts are not matched, the valves or knobs are inflexible, the stove body is not strong enough, the stove surface is deformed seriously after being loaded, and the stove body is warped. Song etc.
3. On-site ignition test
When choosing a cassette furnace, not only the appearance and other processing quality, but also the ignition test. If the fire test conditions are not available in the store, you must test the fire promptly after you buy it home. If it is not easy to use, you should return it in time. During the fire test, the electric ignition device should be flexible and reliable. It should fire 10 times continuously, and it should be fired at least 8 times. The flame should spread throughout the fire eye within 4 seconds without deflagration. A blue flame appears, with distinct cones inside and outside, no backfire, no dead fire, and basically no yellow fire. The flame ignition and extinguishing noise should be small. Otherwise, the fuel gas is not fully burned and the carbon monoxide exceeds the standard, which will endanger human health.
4, weigh the portion
Weigh the cooker by hand. Products that meet the standards have enough weight due to the selection of high-quality materials. Inferior cooking appliances are lighter in weight due to their thin materials.
