Electromagnetic heating coil disk and cooking appliance

Abstract

An electromagnetic heating coil disk and a cooking appliance are provided. The electromagnetic heating coil disk comprises a coil disk bracket, a plurality of magnetic strips, a first coil and a second coil, wherein the plurality of magnetic strips are fixed to the lower surface of the coil disk; the upper surface of the coil disk bracket is provided with a first winding groove and a second winding groove; the first winding groove is located inside the outer end portions of the plurality of magnetic strips; the second winding groove is located outside the outer end portions of the plurality ofmagnetic strips; the first coil is coiled in the first winding groove; and the second coil is coiled in the second winding groove. The second coil is disposed on the edge of the coil disk bracket, and interacts with the magnetic induction lines emitted from the magnetic strips to the outside of the coil disk bracket to generate heat, so as to heat the edge portion of a pot to make the food in thepot uniformly heated. More importantly, the magnetic induction lines of the magnetic strips are effectively utilized to improve the heating efficiency and shield a magnetic field.

Description

technical field [0001] The invention relates to the technical field of electromagnetic heating, in particular to an electromagnetic heating coil disk, and also to a cooking utensil. Background technique [0002] Nowadays, IH heating technology, that is, electromagnetic heating technology, has been widely used in cooking utensils such as induction cooker, rice cooker, and pressure cooker. for cooking. The existing electromagnetic heating coil reel usually includes a reel support, an electromagnetic coil, and a plurality of magnetic strips. The plurality of magnetic strips are usually evenly distributed on the reel support, radiating from the center of the reel support to the periphery, and the electromagnetic coil is tightly wound on the reel. In the winding groove provided on the upper surface of the bracket; the current magnetic strip is generally set in an L-shape or U-shape, that is, at least one upward bending part should be provided at the outer end of the magnetic str...

Problems solved by technology

Existing electromagnetic heating coil reels usually include a reel support, an electromagnetic coil, and a plurality of magnetic strips. The plurality of magnetic strips are usually evenly distributed on the reel support, radiating from the center of the reel support to the periphery, and the electromagnetic coil is tightly wound on the reel. In the winding groove provided on the upper surface of the bracket; the current magnetic strip is generally set in an L-shape or U-shape, that is, at least one upward bending part should be provided at the outer end of the magnetic strip, and the bending part should be inserted into the reel support After installing the preset installation slot, keep the magnetic strip and the wire reel bracket fixed, so that the winding slot on the wire reel bracket must be located inside the installation slot, that is, the outermost edge of the electromagnetic coil is located at the outermost edge of the magnetic strip. The inner side of the outer edge, then the part of the reel bracket located outside the installation groove cannot be effectively used, that is, the magnetic field lines radiated from the magnetic strip to the outer side cannot be effectively used, resulting in low heating efficiency of the electromagnetic heating coil disc, especially Poor heating effect on the edge of the pan
