Patent of electromagnetic shielding net

induction cooktop

It is to generate eddy current on the metal pot to achieve the purpose of heating, not.

electromagnetic radiation

Can't heat. It is not surprising that the publicity of manufacturers is always half-delayed, or partially enlarged.

Their practice is basically to form a shield between the bottom of the pot and the edge of the induction cooker body. The grounding of the shield (power supply grounding) can play a certain role in the electromagnetic leakage of the induction cooker, but it is ignorant to say zero radiation.

Radiation is in different frequency bands. There is still a gap from this shield. The low frequency band can be intercepted, and the high frequency harmonics are more difficult. Moreover, any electromagnetic test equipment has a background and cannot be directly subtracted. if

Measurement data

Close to the background, not 0, can only say that it is very small. Besides, if they publish a full-band

measuring result

Convincing.
