Divided into ordinary type and far-infrared type according to the electric heating elements used; according to whether there is self-purification function (it can automatically change the dirt in the soup into a light gray function that can be wiped easily) is divided into self-purification type and non-self-purification type.
The heating elements used in the electric oven can be roughly divided into three categories: one is a toaster oven with a far-infrared tube and a quartz heating tube, which is the lower grade in all electric ovens. However, the basic electric baking function can still be achieved, but the baking speed is relatively slow. Therefore, it is more suitable for families and single people who are in economic conditions and need to buy electric ovens. The other is an electric oven with two far-infrared tubes and a quartz heating tube, which are characterized by a relatively fast heating rate. However, compared with the former, the price is slightly higher, generally about one or two hundred dollars. There is also a type of ultraviolet heating tube provided in the annex, which can be sterilized, has a high degree of hygiene, and has a high heating speed, so the price is relatively high. It is suitable for consumers with good economic conditions.
