Abstract

The invention discloses a rapid electromagnetic heater which includes a ferrite seat, a magnetic conductive heating plate and an electromagnetic winding. The ferrite seat is provided with an annular accommodating groove which is recessed on a surface of a top side of the ferrite seat. The accommodating groove is provided with at least one externally communicated slit both on the inner side and the outer side of the periphery of the accommodating groove. One magnetic conductive heating plate molded from a high magnetic conductive metal covers above the accommodating groove of the ferrite seat. One electromagnetic winding which is wounded in a ring shape is arranged inside the accommodating groove. The electromagnetic winding has two terminals which respectively extend outwardly from the two slits. Subsequent to being energized, the two terminals enable the electromagnetic winding to generate a high frequency magnetic field loop which acts between the ferrite seat and the magnetic conductive heating plate. The rapid electromagnetic heater uses remanence loss of the magnetic conductive plate, and cooperates with the surface to form an eddy current so as to produce large amount of heat instantly, which can achieve rapid high temperature heating.

Description

technical field

[0001] The invention relates to a fast electromagnetic heater, in particular to an electromagnetic heater structure with excellent heat conversion efficiency and capable of rapid high-temperature heating. Background technique

[0002] Traditional electric heating devices are relatively simple, like ordinary electric furnaces or electric rice cookers, which use the characteristics of electric heating wires or electric heating tubes to generate heat (Q=0.24*I2Rt) after being energized to directly heat the default items or device.

[0003] In addition, as disclosed in the Taiwan Invention Patent Publication No. I471510 "Electric Heating Device" invention patent case, it includes a liquid pipeline divided into a plurality of heating sections, and an electric heating rod is respectively accommodated inside each heating section. The aforementioned electric heating rod It is used to supply heat energy to the liquid flowing through the heating section, so that the t...

Embodiment Construction

[0030] see Figure 1 to Figure 4 As shown, it can be seen that the structure of the first embodiment of the present invention mainly includes: a ferrite base 1, a magnetically conductive heating plate 2, and an electromagnetic winding 3; wherein the ferrite base 1 is a ferrite (fgrrite ) material integrally formed ring structure, the top surface of the ring body is concavely provided with an annular accommodation groove 11, and the inner and outer sides of the accommodation groove 11 are respectively provided with at least one or more slits 12, 13 , so that the side of the aforesaid accommodating groove 11 can communicate with the outside through the two slits 12 , 13 .

[0031] The magnetic conduction heating plate 2 is a highly permeable metal (which can be iron) sheet structure with the same shape as the periphery of the ferrite seat 1. above groove 11.

[0032] The electromagnetic winding 3 is arranged in the accommodating groove 11 of the aforementioned ferrite seat 1, ...
