The heating elements used in electric ovens can be roughly divided into three categories:
One is the electric oven with a far-infrared tube and a quartz heating tube, which is the lower grade of all electric ovens. However, the basic electric baking function can still be realized, but the baking speed will be relatively slow. Therefore, it is more suitable for families with general economic conditions but need to buy electric ovens and single people.
The other is an electric oven with two far-infrared tubes and one quartz heating tube. This kind of oven is characterized by fast heating speed. However, compared with the former, the price is slightly higher, usually one or two hundred yuan. Another type is equipped with an ultraviolet heating tube in the accessory, which can be attached for high-temperature disinfection. It can sterilize and disinfect, with high sanitation and fast heating speed, so the price is more expensive. It is suitable for consumers with good economic conditions.
The last is the electric oven heated by quartz tube. It generally heats the object through radiation. The heating is more uniform and does not contact the heated object, but it is difficult to heat locally; The stainless steel pipe is heated by heat conduction, which is fast and not easy to be uniform, but it can heat locally.
