Description

An electric ceramic heating furnace

technical field

The utility model relates to the field of electrical appliances, in particular to an electric ceramic heating furnace with a special heat insulation layer.

Background technique

Now the general electric heating furnace for cooking is an induction cooker. The induction cooker uses alternating current to generate an alternating magnetic field with a constantly changing direction through the coil. Eddy current will appear inside the conductor in the alternating magnetic field. This is the eddy electric field pushing the conductor. It is caused by the movement of medium carriers; the Joule heating effect of the eddy current heats up the conductor, thereby achieving heating.

Induction cookers must use metal cookers for heating, while electric ceramic cookers generate heat by themselves, so there is no need to use metal cookers, and ceramic cookers can also be used.

The electric ceramic furnace itself is small in size, and the electric ceramic furnace generates a large amount of heat, and its internal control circuit is prone to heat aging, which makes the electric ceramic furnace poor in reliability and durability.
