Which kind of electromagnetic oven is good?
The reliability index of induction cooker is generally expressed by MTBF (average trouble free working time), the unit is "hour", and the quality product should be more than 10 thousand hours. The life of induction cooker mainly depends on the use of the environment, maintenance and the life of the main components. It has been speculated that induction furnaces will enter a period of failure after three or four years.
The quality of the electromagnetic oven for selecting the transistor depends on the quality of the high frequency large power transistor and the ceramic glass-ceramic panel. When buying and selling, be sure to buy high speed, high voltage, high current single high-power transistor electromagnetic oven, because of its good quality, excellent performance, high reliability, not easy to damage.
High quality induction cooker should have automatic adjustment of output power, which can improve power supply adaptability and load adaptability. Some electromagnetic ovens do not have this function, when the power supply voltage rises, the output power rises sharply. When the power supply voltage drops, the power decreases significantly, which brings inconvenience to the users and affects the quality of cooking.
The first is power selection. At present, the power of the electromagnetic oven put on the market is between 800~1800W and divided into several files. The greater the power, the faster the heating rate, but more power consumption, the price is also expensive, therefore, the purchase should be based on the number of meals and the use of the situation. Generally speaking, 3 or so families choose about 1000W; 4~5 candidates 1300W; 6~7 candidates 1600W is appropriate; more than 8 people choose 1800W induction cooker.
The quality of the electromagnetic oven depends on the quality of the high frequency power transistor and the ceramic glass panel. When buying and selling, be sure to buy high-speed, high voltage, high current single high-power transistor electromagnetic oven, because of its good quality, excellent performance, high reliability, not easy to damage. If several large power transistors are used in series or in parallel, there are more problems. For the panel, it is necessary to choose the authentic ceramic glass ceramic panel electromagnetic oven, which is characterized by: milky white, opaque, touch panel printing pattern, feel concave and convex obvious. For the use of heat-resistant plastic or tempered glass panels, easy to burn or cold water caused by cracking and so on. There are always brand models, such as you say you see good beauty beauty also know that this model is good, you can also see the selection, rather than blindly say which brand is good choose which of it, I have to buy electrical appliances do your homework first and then compare different brands
