1. Difference between single microwave oven and combined microwave oven: Combined microwave oven generally refers to barbecue microwave oven with heating tube or light wave tube. Generally, a combined microwave oven is much more expensive than a single microwave oven. When purchasing, consumers should follow their own needs: if they are only hot dishes, hot rice and thawed food, they can choose a microwave oven with a single microwave heating function; If you usually cook in a microwave oven, you can choose a microwave oven with barbecue.
2. The difference between mechanical control and electronic control: the advantages of mechanical control are simple operation, clear understanding and good product reliability, which is suitable for the elderly; The advantage of electronic control is that it can accurately control the heating time. According to different heating foods, there are many options to choose from, and high-end products may have some other additional functions. The disadvantage is that there are many keys, complicated operation and difficult to master.
3. Selection of product volume: The cavity volume of common microwave ovens in the market generally has specifications such as 17L, 18L, 20L, 23L, 28L and 30L. Manufacturers can use the same cavity size to develop microwave ovens with different models and microwave output power. Theoretically speaking, under the condition of constant microwave output power, the larger the cavity, the better the heating uniformity, but the lower the heating efficiency, but this difference is almost imperceptible in use. Other things being equal, the larger the cavity, the higher the price of the whole machine. Generally speaking, there is no direct correspondence between the volume of microwave oven cavity and the family population. For ordinary families, it can be selected in the range of 20L~30L, and the better cavity volume is about 23L. When purchasing, we mainly consider living habits, dependence on microwave ovens, housing conditions, economic affordability and other factors.
