Abstract

The invention discloses a novel induction cooker with an ultrasonic cleaning function. The novel induction cooker utilizes the similarity of the working frequency of an ultrasonic cleaning machine andthe working frequency of the induction cooker, and the ultrasonic cleaning function and the electromagnetic heating function are achieved at the same time through a shared high-frequency current generation module on the premise that the cost is close to that of an induction cooker in the prior art.

Description

Technical field[0001]The invention relates to the technical field of electromagnetic heating equipment and the technical field of ultrasonic cleaning equipment, and in particular to an electromagnetic oven with ultrasonic cleaning function.Background technique[0002]Existing electromagnetic heating equipment refers to equipment that is heated by the principle of electromagnetic induction. It usually works in magnetic induction eddy current heating, that is, using a certain frequency of current to generate a magnetic field through a heating coil, and the heated equipment generates heat energy through the eddy current generated by magnetic induction, for example, Induction cooker, electromagnetic induction heater, etc.[0003]The prior art induction cooker generally consists of a rectifier module, an IGBT module, a main control module, and a heating coil.[0004]The existing electromagnetic heating equipment has the disadvantage of single function.[0005]The principle of the existing ultras...
