Description

Electromagnetic stove

Technical Field

The utility model relates to an electromagnetism stove especially relates to an induction cooker.

Background

The principle of the electromagnetic oven is that alternating current generates an alternating magnetic field with constantly changing direction by passing through a coil in the electromagnetic oven, vortex current can appear in a conductor (namely, a pot) in the alternating magnetic field, and the pot is heated by the joule heat effect of the vortex current, so that heating is realized. However, since the electromagnetic oven heats the pot by electromagnetic radiation, not by open fire, the user does not have the intuitive feeling like open fire heating during use, and only can control the fire by relying on the gear switch. The coil is buried in the electromagnetic oven and invisible outside, so that a user cannot specifically judge the central area of the coil with the highest temperature, and the cookware cannot be accurately placed on the central area. In addition, the display screen of the induction cooker can only provide a single temperature value, and for areas of the cooking surface with a relatively large area, it is difficult for a user to accurately know the temperature difference of each area of the cooking surface in real time. Particularly, when the induction cooker stops working, the temperature of the cooking surface is still high, and people easily stretch out hands to touch the cooking surface, so that safety accidents such as scalding are caused.
