Title:
ELECTROMAGNETIC COOKING APPLIANCE AND POWER CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/119640
Kind Code:
A1
Abstract:
Provided is a power control method for an electromagnetic cooking appliance, wherein the method comprises the following steps: step S1, obtaining a target power of the electromagnetic cooking appliance; step S2, determining a heating cycle of the electromagnetic cooking appliance according to the target power, wherein each heating cycle includes at least one heating period; step S3, controlling the power switch (40) corresponding to the first coil disk (70) with a first control pulse during each heating period, and controlling the power switch (50) corresponding to the second coil disk (80) with a second control pulse, so as to heat the first coil disk (70) and the second coil disk (80) simultaneously but at different powers, wherein, when the first coil disk (70) and the second coil disk (80) are simultaneously heated, the start-up time of the power switch (40) corresponding to the first coil disk (70) at each switching cycle is the same as the start-up time of the power switch (50) corresponding to the second coil disk (80) at each switching cycle. Provided is also an electromagnetic cooking appliance using the above power control method, which enables multiple coil disks to be heated simultaneously with different powers.
