摘要： The present invention provides a heating device and a control method thereof. The heating device includes 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 its own impedance. The control method includes: controlling an electromagnetic wave generating module to generate an electromagnetic wave signal of a preset heating power; and determining a load matching degree of the electromagnetic wave generating module, and adjusting impedance of the matching module based on the load matching degree. When the load matching degrees determined within a preset adjustment time are all less than or equal to a first matching threshold, the electromagnetic wave generating module is controlled to stop working, such that the object to be processed that contains more components having a poor electromagnetic wave absorption capacity is prevented from being continuously heated after its moisture has been converted from ice to liquid, which further prevents the object to be processed from being overheated, guarantees the quality of the object to be processed, reduces undesired waste of energy, and hence prolongs the service life of the electromagnetic wave generating module.
