Abstract

The invention discloses a multi-coil electromagnetic induction circuit and a heating method, the multi-coil electromagnetic induction circuit comprises a controller, at least two inversion output circuits and a plurality of LC oscillation units, and each LC oscillation unit is connected with the plurality of inversion output circuits through a multi-way switch; the controller is connected with the multi-way switch, when the large cookware arranged on the LC oscillation units is heated, the multi-way switch is controlled through the controller, and therefore the LC oscillation units are driven through the same inverter output circuit.

Description

technical field [0001] The invention relates to the field of electromagnetic induction heating, in particular to a multi-coil electromagnetic induction circuit and a heating method. Background technique [0002] In the field of multi-head induction cookers, the existing technology generally uses two heating units to work at high speed and time-sharing, or two heating units work at the same frequency to achieve bridging or zoneless functions. The control method is very complicated and the effect is not perfect. For example, the use of time-sharing In the working mode, the two burners always have a "woo woo" sound when the water is quickly turned on; and when the same frequency is used, the two burners are likely to interfere with each other at the moment of startup, resulting in abnormal pot inspection. When the materials of the load pans on the two burners are quite different, a whistling sound will be emitted. Therefore, there is a need for a multi-coil electromagnetic ind...
