Problems solved by technology
For pots that are commonly used and whose parameters have not changed, they can usually better match the working time under the corresponding power, but for pots that are not frequently used, the material parameters of the pot have a large deviation from the material parameters of general pots, and it is difficult to pass Look up the table to get the driving scheme in the program, resulting in the cookware not being well compatible, resulting in a relatively large output power deviation and poor product reliability

The invention provides a heating control method, control system and electromagnetic heating device, wherein the heating control method includes the following steps: after putting cookware to be judged in a designated area of a heating control device, obtaining a sampling signal of a collector within designated time after applying an electric load signal with a designated duty ratio to the collector; judging whether a zero-crossing conduction signal occurs according to the sampling signal; when judging that the zero-crossing conduction signal occurs, determining the duration of the zero-crossing conduction signal; judging whether the duration is matched with zero-crossing conduction time of a preset cookware type; and when judging that the duration is not matched with the zero-crossing conduction time of the preset cookware type, prompting that the cookware to be judged is not matched with the preset cookware type, and stopping heating the cookware to be judged. Through the technical scheme of the invention, the cooking efficiency is improved, power consumption is reduced, and user experience is improved.
Description
technical field [0001] The present invention relates to the technical field of household appliances, and more specifically, to a heating control method of an electromagnetic heating device and an electromagnetic heating device. Background technique [0002] In the relevant electromagnetic heating device technology, the driving scheme of the existing induction cooker IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor) is solidified in the program of the controller, and the type of the pot is determined through the pot judgment program. When the induction cooker is working, the driving scheme in the program is found by looking up the table to control the induction cooker to heat. For pots that are commonly used and whose parameters have not changed, they can usually better match the working time under the corresponding power, but for pots that are not frequently used, the material parameters of the pot have a large deviation from the material parameters...
