Title:
METHOD FOR CONTROLLING HEATING DEVICE, AND HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/139387
Kind Code:
A1
Abstract:
A method for controlling a heating device, and the heating device. The heating device comprises an electromagnetic wave generating module configured to generate an electromagnetic wave signal for heating an object to be processed, and a matching module configured to adjust load impedance of the electromagnetic wave generating module by adjusting own impedance. The matching module comprises a first matching unit configured to adjust a matching frequency point and a second matching unit configured to adjust the amplitude of the frequency point. The control method comprises: controlling an electromagnetic wave generating module to generate an electromagnetic wave signal of preset initial power; adjusting impedances of a first matching unit and a second matching unit, and determining an impedance value of the first matching unit matching an optimal load of the electromagnetic wave generating module; and determining a feature parameter of said object according to the impedance value of the first matching unit. According to the control method, there is no need for a user to manually input the feature parameters of said object based on experience or after measurement, sensing devices for correspondingly sensing feature parameters in a cavity capacitor are reduced, thereby saving costs and reducing errors of feature parameters.
