Coil disc for electromagnetic cooker and coiling method thereof

Abstract

The invention discloses a coil disc for an electromagnetic cooker and a coiling method thereof. The coil disc comprises a coil, a bracket and a magnetic strip, wherein the bracket comprises an outer frame, a magnetic strip slot and a central circle, wherein two ends of the magnetic strip slot are respectively connected with the central circle and the outer frame, and the magnetic strip is embedded in the magnetic strip; and the coil is wound on the bracket by dividing an upper layer and a lower layer. The coil disc adopts a co-winding double-layer enameled wire, avoids the wire jamming phenomenon and the short-circuit phenomenon among rings, shortens the diameter of the coil, solves the difficult problem of concentric circle coil guide which exists for a long time and the problem of difficult heat dissipation of the coil, reduces the current loss, improves the heat efficiency, reduces the disc diameter of the coil disc by 30 percent compared with the common winding way, averagely improves the Q value by 15 percent, reduces the current loss by 15 percent and prolongs the service life of the coil disc. In addition, the invention achieves the aim of saving the cost on the premise of ensuring the same energy efficiency standard as the coil adopts an aluminum enameled wire.

Description

technical field [0001] The invention relates to the field of electromagnetic ovens, in particular to a wire reel for an electromagnetic oven and a winding method. Background technique [0002] The induction cooker mainly uses the principle of electromagnetic induction to generate eddy currents at the bottom of the iron pan, thereby generating a large amount of heat energy to directly heat the pan body rapidly. As a new type of small kitchen appliance, it is quickly popularized due to its advantages of no open flame and high thermal efficiency. In the household appliances going to the countryside, it is clear that the thermal efficiency of the induction cooker must reach level three (including level three). The heating device is a coil disk, and the function of the coil disk is to convert high-frequency current into magnetic energy to generate magnetic force lines, which pass through the bottom of the pot to generate eddy currents at the bottom of the pot, thereby generating...
