Electromagnetic heating inner container

Abstract

The invention discloses an electromagnetic heating inner container. The electromagnetic heating inner container comprises a small pipeline, a medium pipeline and a big pipeline; a water inlet cavity is formed between the medium pipeline and the big pipeline; a heating pipeline structure is arranged between the medium pipeline and the small pipeline and comprises a first pipeline, an electromagnetic heating coil and a second pipeline; the electromagnetic heating coil is located between the first pipeline and the second pipeline and wound on the outer surface of the first pipeline; a second heat conducting cavity is formed between the second pipeline and the medium pipeline; the small pipeline is provided with a water outlet channel; the second heat conducting cavity and the water outlet channel communicate with the water inlet cavity; a first heat conducting cavity is formed between the inner wall of the first pipeline and the outer wall of the small pipeline; and multiple water flowing holes are formed in the wall of the small pipeline and communicate with the first heat conducting cavity and the second heat conducting cavity. The electromagnetic heating inner container can promote heat energy generated by the heated pipelines and the electromagnetic heating coil to be taken away by water to the maximum extent, then the service life of the electromagnetic heating coil and the service life of the pipelines are prolonged, and the utilization rate of the energy is greatly increased.

Description

technical field [0001] The invention relates to a heating inner container, in particular to an electromagnetic heating inner container. Background technique [0002] The principle of electromagnetic heating is to generate an alternating magnetic field through the components of the electronic circuit board. When a ferrous container is placed on it, the surface of the container cuts the alternating magnetic force lines and generates an alternating current (ie eddy current) at the metal part of the bottom of the container. The iron atoms at the bottom of the container move at high speed and irregularly, and the atoms collide and rub against each other to generate heat energy, thereby heating the object. [0003] The existing electromagnetic heating liner often directly wraps the electromagnetic heating coil on the outer surface of the pipeline to heat the pipeline, which will cause the heat of the electromagnetic heating coil to be difficult to dissipate, thereby reducing the s...

Problems solved by technology

[0005] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art, and to provide an electromagnetic heating liner to overcome the fact that the existing electromagnetic heating liner often directly wraps the electromagnetic heating coil around the outer surface of the pipeline to heat the pipeline, resulting in The heat of the electromagnetic heating coil is difficult to dissipate and the heat on the outer surface of the pipeline is not fully transferred to the inside of the pipeline, which reduces the service life of the electromagnetic heating coil and pipeline and the technical defects of low heat utilization
