Title:
ELECTROMAGNETIC COOKWARE AND POWER CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/119641
Kind Code:
A1
Abstract:
Electromagnetic cookware and a power control method therefor. The electromagnetic cookware comprises a first coil disk (70) and a second coil disk (80), wherein the first coil disk (70) and the second coil disk (80) respectively correspond to an independent resonance loop. The power control method can comprise the following steps: acquiring a target power of electromagnetic cookware (S1); determining a heating cycle of the electromagnetic cookware according to the target power, wherein each heating cycle comprises at least one first heating period and at least one second heating period (S2); and controlling the first coil disk to heat in the first heating period, and controlling the second coil disk to heat in the second heating period, wherein each first heating period is immediately followed by a second heating period, so that the first coil disk and the second coil disk complement each other in heating (S3). By means of the control method, heating by rapidly switching between multiple coil disks and heating with different powers can be realized, and the interference from a harmonic current and voltage flicker can also be reduced.
