Abstract

The invention discloses a control method of an electromagnetic device, the electromagnetic device and a storage medium. The control method of the electromagnetic device comprises : detecting whether an object is placed in the electromagnetic device or not; if yes, detecting whether the object is to-be-charged equipment or not to obtain a first detection result; if the first detection result is yes, controlling an LC oscillation circuit to charge the to-be-charged equipment at a first oscillation frequency; if the first detection result is negative, detecting whether the object is to-be-heatedequipment or not to obtain a second detection result; and if the second detection result is yes, controlling the LC oscillation circuit to heat the to-be-heated equipment at a second oscillation frequency. The electromagnetic device can charge the to-be-charged equipment and heat the to-be-heated equipment on the premise of protecting the to-be-charged equipment.

Description

technical field [0001] The invention belongs to the technical field of equipment control, and in particular relates to a control method of an electromagnetic device, an electromagnetic device and a storage medium. Background technique [0002] With the continuous development of electromagnetic induction theory and application, more and more wireless charging products, such as mobile phones and electric toothbrushes, have appeared on the market. The principle of wireless charging is to install a receiving coil inside the product. When the product is placed in a changing magnetic field, the receiving coil generates an induced current to charge the battery in the product. A wireless charger is a device that generates a changing magnetic field at a specific frequency. [0003] At present, there are some heating devices using electromagnetic induction, such as induction cooker and IH rice cooker, which generate changing magnetic fields through the resonance of the electromagneti...
