Problems solved by technology

[0004] When the induction cooker is working, the high-frequency magnetic field generated by the coil plate not only has a heating effect on the pan on the panel, but also has a high-frequency magnetic field leaking from the induction cooker, which will bring adverse effects to the user or interfere with the normal operation of other electrical products in severe cases.
In order to reduce this electromagnetic leakage, a magnetic strip is generally placed at the bottom of the coil disk, but because the magnetic force lines passing through the magnetic strip are relatively concentrated, the coil disk still produces a large electromagnetic leakage in the radial direction of the magnetic strip position

Abstract

The invention discloses an electromagnetic oven. The electromagnetic oven comprises a housing, a panel, a control circuit board, a coil disc and a magnetic stripe device arranged inside the coil disc,wherein the magnetic stripe device comprises a plurality of magnetic stripes which are independent from one another; the magnetic stripes are arranged in the form of a circular array by taking the center of the coil disc as the center of a circle; a magnetic shielding part is arranged at the radial outer side of the magnetic stripe device; and the magnetic shielding part is fixedly arranged on the outer wall of the coil disc. According to the electromagnetic oven disclosed by the invention, the magnetic shielding part is arranged at the radial outer side of the magnetic stripe device, and themagnetic shielding part generates induction current under action of high-frequency magnetic fields, so that electromagnetic leakage of the electromagnetic oven is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an electromagnetic cooker. Background technique [0002] Induction cooker is popular among consumers for its advantages of multi-purpose, no open flame, high efficiency, no pollution and easy cleaning. [0003] The induction cooker is generally composed of a shell, a panel, a control circuit board, and a coil plate. The high-frequency current generated by the control circuit board flows into the coil plate, and the coil plate generates a high-frequency magnetic field. The cooker on the panel generates eddy currents under the action of the high-frequency magnetic field Fever, to achieve the purpose of heating. [0004] When the induction cooker is working, the high-frequency magnetic field generated by the coil plate not only has a heating effect on the pan on the panel, but also has a high-frequency magnetic field leaking from the induction cooker, which will bring ...
