First of all, the hot pot induction cooker manufacturer should observe whether the panel is flat and damageless (avoid bumps or tilts), then check the bottom cooling fan, and try to choose a product with a larger fan diagonal size. The level of heat dissipation efficiency will affect the normal service life of internal components. The power plug is suitable for three plugs. After seeing the appearance, we need to turn on the power supply to ensure that in addition to the normal sound of the cooling fan, no other noise or obvious current sound can be heard.

reliability and useful life. The reliability index of hot pot induction cooker manufacturers is generally expressed by MTBF (mean time between failures), the unit is "hours", and high-quality products should be more than 10,000 hours. The life of the induction cooker mainly depends on the use environment, maintenance and the life of the main components. It is speculated that the induction cooker will enter its expiration date after three or four years of use.

Power output stability. A good hot pot induction cooker manufacturer should have the function of automatic adjustment of output power, which can improve the adaptability of power supply and load. Some hot pot induction cooker manufacturers do not have this function. When the power supply voltage increases, the output power increases sharply; when the power supply voltage drops, the power decreases significantly, which will bring inconvenience to users and affect the cooking quality.

At the same time, we should also ask the origin of the panels of the hot pot induction cooker manufacturers, preferably imported or domestic panels. In addition, it is also very important whether the products have the functions they need, such as automatic alarm or automatic shutdown and other functions. In the end, it is better to actually operate the product to confirm whether each button can be used normally, so as to avoid the trouble of return and exchange. If you do not pay attention to maintenance after buying a hot pot induction cooker, it will also affect the service life of the product. In fact, the maintenance of hot pot induction cooker is not difficult.
