Description

Air inlet protection device suitable for electric cooker or electric stove

Technical Field

The utility model relates to an Induction Heating technical field specifically relates to an air inlet protection device suitable for electric rice cooker or electric cooker, especially relates to an air inlet protection architecture of intelligence IH (Induction Heating) system.

Background

An Electromagnetic induction heater (Electromagnetic induction heater) is a heating controller manufactured based on the Electromagnetic induction heating principle.

Electromagnetic induction heating results from the phenomenon of electromagnetic induction found by faraday, i.e., an alternating magnetic field generates an induced current in a conductor, causing the conductor to heat. Since the discovery of the thermal effects of current flowing through the wire, many inventors have developed electrical heaters in the world. In 1890, Swedish technicians invented a first induction melting furnace, namely a slotted cored furnace; in 1893, the united states presented an iron prototype; in 1909, the electric cooker realizes the process of converting electric energy into heat energy; in 1916, a closed-slot core furnace was invented by us, and the electromagnetic induction technology gradually enters into the practical stage.

But for similar heating stoves, produce the temperature rise to inside electronic components when heating, have harm to electronic components, if the high temperature can influence the life-span and the use of components and parts and even do not work.
