Electromagnetic wire coil, manufacturing method thereof and induction cooker with wire coil

Abstract

The invention provides an electromagnetic wire coil, which comprises a wire coil rack and a wire coil; and granular or powdery magnetic substances are dispersed in the wire coil rack. Another aim of the invention is to provide a method for manufacturing the electromagnetic wire coil and an induction cooker. By directly adding the magnetic substances to the wire coil rack, the electromagnetic wire coil makes the wire coil rack act as an original magnetic bar, and can cancel all the magnetic bars used in the prior art; and for the action of the magnetic substances, magnetic lines are collected so as to promote thermal efficiency and reduce magnetic leakage and electromagnetic radiation. In addition, as the setting of the magnetic bars can be cancelled, the wire coil reduces the cost and the working procedure of assembling the magnetic bars; the wire coil rack is directly molded in an injection mode or the magnetic substances are extruded into the wire coil rack by an external force extrusion mode; and compared with the prior art, the electromagnetic wire coil is easier to process and reduces the production cost and the material cost of products.

Description

technical field [0001] The invention relates to the technical field of an electromagnetic cooker and an electromagnetic cooker, in particular to an electromagnetic wire reel and a manufacturing method of the electromagnetic wire reel, and also relates to an electromagnetic cooker with the electromagnetic wire reel. Background technique [0002] The "Implementation Rules for Household Induction Cooker Energy Efficiency Labeling" promulgated by the relevant state departments requires that from March 1, 2009, manufacturers are required to affix energy efficiency labels on the surface of induction cookers and induction cooker products, and products without energy efficiency labels are not allowed. production and sales. In addition, due to the improvement of consumers' requirements for environmental protection and health, manufacturers of induction cookers and induction cookers are prompted to research a new generation of high-efficiency electromagnetic coils in order to reduce r...

AI Technical Summary

Problems solved by technology

The above-mentioned methods are to improve the performance of the induction cooker and induction cooker through external means, and the above-mentioned increase of coil material, increase of anti-magnetic leakage ring or selection of magnetic materials with high permeability to make magnetic strips are inevitable. It will bring about the problems of increased cost, increased assembly operation process, complex process, and reduced work efficiency. In addition, the above three methods generally cannot achieve the effects of improving thermal efficiency and reducing magnetic radiation at the same time.
