Difference between frequency conversion microwave oven and ordinary microwave oven
1. Frequency conversion microwave oven adopts the most advanced frequency conversion technology in the world at present, and converts the 50 Hz power frequency of household power supply system into the high frequency output of 10000 ~ 30000Hz at will.
2. The traditional microwave oven outputs constant power at a fixed frequency of 50 Hz. If you need to output different power, you can only simulate the control through the on/off time interval, which will lead to the uneven phenomenon that part of the heated food is repeatedly heated and the other part is insufficiently heated; Panasonic, known as the originator of microwave oven, has successfully applied frequency conversion technology to microwave oven after more than 20 years of painstaking research, and controlled different output power by changing the frequency, thus achieving the effect of freely controlling the strength of firepower, so that the heated food is heated evenly in all directions, thus making the cooked food taste better and losing less nutrition. Frequency conversion technology can save more than 20% electricity compared with traditional microwave ovens by improving power supply efficiency and reducing standby power consumption.
3. The frequency conversion barbecue microwave oven endows it with the characteristics of using microwave and barbecue functions at the same time, which greatly shortens the cooking time. In addition, the transformer and other bulky components in the mechanical part of the microwave oven are integrated on a single frequency conversion circuit board, which not only eliminates noise, but also makes the microwave oven light and compact as a whole.
Brief introduction of variable frequency microwave oven
Frequency conversion microwave oven adopts the most advanced frequency conversion technology in the world at present, which converts the power frequency of 50 Hz in household power supply system into high frequency output of 10000 ~ 30000Hz at will. By changing the frequency to control different output power, the effect of freely controlling the strength of firepower can be achieved, so that the heated food can be heated evenly in all directions, and the cooked food has a better taste and less nutritional loss.
Frequency conversion technology can save more than 20% electricity compared with traditional microwave ovens by improving power supply efficiency and reducing standby power consumption. Frequency conversion barbecue microwave oven gives it the characteristics of using microwave and barbecue function at the same time, which greatly shortens the cooking time. In addition, the transformer and other bulky components in the mechanical part of the microwave oven are integrated on a single frequency conversion circuit board, which not only eliminates noise, but also makes the microwave oven light and compact as a whole.
Is the inverter microwave oven really good?
Different from the traditional microwave oven, which is easy to heat unevenly, the frequency conversion microwave oven can meet the requirements of different foods for different firepower by using the microwave energy that is automatically adjusted and continuously output, and truly realize the automatic adjustment from strong fire to weak fire. It not only ensures the taste and color of food, but also fully retains the nutritional components of food. Moreover, the surface or edge of food will not be burnt when cooking with low power for a long time.
In the cooking speed, the inverter is used to replace the high-voltage transformer and high-voltage capacitor, which reduces the loss of power conversion part, improves the thermal efficiency by more than 5%, and increases the effective power by nearly 10%. Under the same conditions, the cooking time was shortened by 65438 00%. In terms of energy saving, the energy efficiency is as high as 64%, which is 62% higher than the national first-class energy consumption standard.
What's the difference between frequency conversion of microwave oven and ordinary one?
Mainly because of the difference of internal strength, the frequency conversion microwave oven adopts the most advanced frequency conversion technology in the world at present, which converts the power frequency of 50 Hz in the domestic power supply system into the high frequency output of 10000 ~ 30000Hz at will. The traditional microwave oven outputs constant power at a fixed frequency of 50 Hz. If different power needs to be output, it can only be simulated by the length of on/off time interval, which will lead to the uneven phenomenon that part of the heated food is repeatedly heated and the other part is insufficiently heated. Different from the traditional microwave oven, which is easy to heat unevenly, the frequency conversion microwave oven can meet the requirements of different foods for different firepower by using the microwave energy that is automatically adjusted and continuously output, and truly realize the automatic adjustment from strong fire to weak fire. It not only ensures the taste and color of food, but also fully retains the nutritional components of food. Moreover, the surface or edge of food will not be burnt when cooking with low power for a long time.
Benefits of variable frequency microwave oven
1, saving energy. Because of the frequency conversion technology, the energy efficiency is higher.
2. Smaller size or larger use space. The microwave oven with frequency conversion technology is smaller, which can save more space for food.
This food tastes better. Because the power of the inverter microwave oven is continuously adjustable, unlike the past microwave ovens, which adjust the power by adjusting the power output time, the chef can choose the appropriate power to heat the food according to the type of food.
4. Food is healthier. Because the power is adjustable, there is no need to heat the food with high power of 1000W, so the damage to the nutritional components of the food is very small.
It can be said that the above four kinds of propaganda are reasonable. However, articles 1 and 2 are not very practical. The microwave oven itself is very efficient, the energy consumption of cooking is limited, and the energy-saving effect is not obvious. As for saving space, most consumers don't care much.
Compared with the past microwave ovens, the attraction of inverter microwave ovens mainly focuses on the latter two aspects, namely, food taste and nutrition maintenance. From a health point of view, if the price is not too high, the inverter microwave oven can indeed replace the traditional microwave oven.
However, what manufacturers have not (and will never) tell us is that microwave ovens and foods processed by microwave ovens are harmful to human health. At least compared with the traditional heating method, there is a potential threat. The principle of microwave heating is that microwave can quickly change the polarity of water molecules in food, which should destroy the structure of food in principle.
