Title:
COOKING APPARATUS AND CONTROLLING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/040238
Kind Code:
A1
Abstract:
A cooking apparatus and a controlling method, where the cooking apparatus includes a plurality of power input terminals, a plurality of heaters, a detection circuit connected to the power input terminals for detecting the phase of power input into the power input terminals, and a processor. The processor configured to identify a phase difference of input power based on an electronic signal of the power output from the detection circuit, and, based on the phase difference being within one of a plurality of threshold ranges, identify the voltage between live terminals among the plurality of power input terminals based on the phase difference of the power and control at least one heater among the plurality of heaters according to the identified voltage between the live terminals, and, based on the phase difference being outside the plurality of threshold ranges, stop the operation of the cooking apparatus.
