Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, electromagnetic induction heating coil dish of the present utility model, include wire coil bracket 2, be wound with at least two solenoids 1 that mutually keep electrical connection on wire coil bracket 2, wherein the bottom of wire coil bracket 2 is equiped with magnetic core 3, wire coil bracket 2 is fixed on magnetic core 3, and the geometric center position of corresponding each solenoid 1 of magnetic core 3 is provided with the magnetic post 31 of projection, and magnetic post 31 passes solenoid 1 set space, geometric center position.Above-mentioned magnetic post 31 is made separately, refill to fit on magnetic core 3, or magnetic post 31 is made with magnetic core 3 one.In the present embodiment, magnetic post 31 is made with magnetic core 3 one.
The outer of above-mentioned magnetic core 3 is provided with the abutment wall 32 that raises up, and wire coil bracket 2 is installed in the set abutment wall of magnetic core 3 32.
Above-mentioned each solenoid 1 is wound on separately wire coil bracket 2, and wire coil bracket 2 separately all is fixed on magnetic core 3, or all solenoids 1 are wound on integrally formed overall wire disc carrier 2, and overall wire disc carrier 2 is fixed on magnetic core 3.
Above-mentioned wire coil bracket 2 bottoms are provided with several elastic fastening hooks 21, and magnetic core 3 is provided with the draw-in groove 33 that cooperatively interacts with grab 21 in the position of corresponding grab 21, and wire coil bracket 2 buckles into the set draw-in groove 33 of magnetic core 3 by set grab 21 and is solidly installed with magnetic core 3.
In the present embodiment, be provided with two solenoids 1 of series connection mutually, and the current opposite in direction of two solenoids 1; The wire coil bracket 2 of each solenoid 1 of coiling is formed as one, and its upper surface offers respectively two groups of that arrange with one heart, that ovalize distributes wire casings, and solenoid 1 is formed by enamelled wire continuous coiling in wire casing.
The pan heating region distributes as figure as shown in shadow region in Fig. 5; The pan central area magnetic line of force is subject to the magnetic fields that two coils produce, because two solenoid 1 adjacent area magnetic directions are opposite, so this magnetic field, central area has obtained reinforcement; The strong induced electromotive force in magnetic field also strengthens, and it is large that the induced current of generation also becomes naturally, therefore forms the thermal treatment zone, center; Because two solenoid 1 centers arrange bossed magnetic post 31, from the magnetic line of force on magnetic post 1 surface be with radial towards surrounding, repel mutually with the magnetic line of force around its, therefore respectively form an annular-heating zone in pan both sides.
The difference of the present embodiment and embodiment 1 is, electromagnetic induction heating coil dish of the present utility model comprises the solenoid 1 of four series connection, its pan heating region distributes as shown in the shadow region in Fig. 6, has respectively annular-heating regional in pan central area and both sides.Solenoid 1 is the even number setting, and the area that number is more added focus and heating is just more, so just can more optimize the uniformity of heating.
