Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic heating, in particular to a multi-stage electromagnetic induction heating device. Background Art

[0002] Electromagnetic heating is also called electromagnetic induction heating, that is, electromagnetic heating (foreign: Electromagneticheating abbreviation: EH) technology. The principle of electromagnetic heating is to generate an alternating magnetic field through the components of the electronic circuit board. When an iron container is placed on it, the surface of the container cuts the alternating magnetic field lines and generates alternating current (eddy current) in the metal part at the bottom of the container. The eddy current causes the carriers at the bottom of the container to move irregularly at high speed, and the carriers and atoms collide and rub against each other to generate heat energy. This has the effect of heating objects. Because the iron container itself generates heat, the heat conversion rate is particularly high, up to 95%, which is a direct heating method. Induction cookers, induction stoves, and electromagnetic heating rice cookers all use electromagnetic heating technology.

[0003] Chinese utility model patent: Publication number CN203136212U discloses an electromagnetic induction heating device, including an electromagnetic coil, an inner side of which is provided with a heat insulation layer, and the electromagnetic coil is connected to an external power supply through an external power supply terminal.

[0004] In the existing technology, when CN203136212U is in use, the heating device improves the heating efficiency ratio to more than 85% through a reasonable structure, especially a modular electromagnetic heating structure, which saves nearly 50% energy compared with traditional resistance heating. At the same time, it avoids the problem of insulation aging caused by long-term heating of traditional resistance heating coils, which causes leakage and high temperature of the traditional resistance heating coils, which poses a safety hazard to operators at work, and is conducive to lowering the working room temperature. The modular structure also improves its adaptability and can be applied to various injection molding machines with good economic benefits.

[0005] However, in actual use, the heating temperature of the electromagnetic coil is relatively fixed, which makes it difficult to adjust the heating temperature of the electromagnetic coil according to different materials, resulting in higher energy consumption in actual use.
