With modeling magnetic bracket 10, insulating support 20 and the coil group 30 of ductile material injection molding, 30 disk of coil group is located at modeling magnetic bracket 10
On, the setting of insulating support 20 is between modeling magnetic bracket 10 and coil group 30.
The bottom thickness for moulding magnetic bracket 10 is identical along the radial direction of coil group 30, and the bottom thickness range of modeling magnetic bracket 10 is
1.2-2.0mm。
It should be noted that being provided with modeling magnetic bracket 10, insulating support 20 and line in coil panel 100 provided in this embodiment
Circle group 30, wherein modeling magnetic bracket 10 is by magnetisable material and ductile material injection molding, which can be magnetism
The mixture of any one or more in powder, magnetic-particle, magnetism stick and magnetic piece.Magnetisable material may include ferromagnetic oxidation
Object, Ferrimagnetic oxide, one of neodymium iron boron, samarium-cobalt magnet, alnico magnet and siderochrome cobalt magnet or a variety of, the present embodiment
Type and structure to magnetisable material are simultaneously without restriction, are also not limited to above-mentioned example.
Magnetisable material and ductile material are by the way that after injection molding, magnetisable material can be dispersed in the interior of the modeling magnetic bracket 10
Portion, to play the effect of magnetic conduction.Compared to existing coil panel, being used for magnetic conduction is multiple magnetic that coil bottom is arranged in
Item, and the magnetic stripe mostly passes through Magnaglo sinter molding, is needed in use through assembling, and the magnetic stripe of sintered body
The larger easy fracture of brittleness, therefore preparation, installation and service life are undesirable.And modeling magnetic bracket 10 provided in this embodiment,
Due to being added to magnetisable material, identical magnetic conduction effect can achieve, and can be by adjusting ductile material and magnetism
The ratio of substance has adjusted optimal magnetic conduction effect.It based on the modeling magnetic bracket 10 therefore is eliminated existing by injection molding
The step of magnetic stripe assembles in coil panel, can greatly simplify the process of coil panel 100, to improve its preparation efficiency.Into
One step, since the modeling magnetic bracket 10 is added to ductile material, toughness can be improved, prevent from being broken in use,
To extend the service life of the coil panel 100.
The coil group 30 is that disk is located on modeling magnetic bracket 10, and coil group 30 may include one or more snippets, i.e. the coil group
30 can be formed by one section of coil winding, can also be by multistage coil rotating around individual coil is made, finally again will be single
Only coil splicing is to form coil group 30.The coil group 30 is limited in the present embodiment to form by least two sections of coil windings, it should
Two sections of coils are that can pass through connecting line between at least two sections of coils by being spliced to form coil panel 100 after independent coiling
33 connections, finally connect with the control circuit of coil panel 100, are also possible to each individual coil and all have connecting line 33, and
It is not connected to mutually between respectively, respectively connects to the control circuit.In the actual use process, the structure of coil group 30 and
Route design can according to need setting, the present embodiment to this and it is without restriction, be also not limited to above-mentioned example.
It should be pointed out that be provided with circular bar 50 on modeling magnetic bracket 10 provided in this embodiment, which can be with
Disk is located at one of unilateral or opposite sides of circular bar 50, and setting keeps away line portion in circular bar 50.This keeps away the main work in line portion
With being passed through for the connecting line 33 of coil group 30.When one of unilateral side of circular bar 50 is arranged in coil group 30, the connection
Line 33 can be the connecting line 33 of coil group 30 Yu control circuit, and when coil panel 100 is separately positioned on the opposite of circular bar 50
When two sides, which can be the connecting line 33 between two independent coils.
Further, it is additionally provided with insulating support 20 between the coil panel 100 and modeling magnetic bracket 10, which is
By plastic material injection molding, it is high molecular material based on general plastic material, there is insulating properties.When the coil panel 100
When work, coil inside is passed through electric current, and due to having magnetisable material inside modeling magnetic bracket 10, when the electric current of coil inside is excessive
And when coil group 30 and the modeling abutting of magnetic bracket 10, coil is influenced by magnetisable material, and electric current can puncture the enamel-cover of coil outer
Layer, to seriously affect the normal use of coil panel 100 and the personal safety of user there is a phenomenon where leaking electricity.On avoiding
The generation of phenomenon is stated, in coil panel 100 and is moulded the insulating support 20 setting between magnetic bracket 10 in the present embodiment, based on insulation
Bracket 20 has certain thickness, can play the role of spatially completely cutting off to the two, and the insulation based on insulating support 20
Property, it is possible to reduce the interaction of coil inside electric current and magnetisable material prevents leaky, ensure that coil panel 100
Normal use and user personal safety.
It should be noted that the bottom thickness of modeling magnetic bracket 10 provided in this embodiment is identical along the radial direction of coil group 30,
Since coil group 30 is that disk is located on modeling magnetic bracket 10, magnetic branch substantially along the circumferential direction of coil panel 100, is moulded in the coiling direction of coil
The bottom thickness of frame 10 has influence to the magnetic conduction effect of coil group 30 in the distribution radially along coil group 30.Based on modeling magnetic
The thickness of bracket 10 will have a direct impact on 100 inductance of coil panel and Q value (quality factor), and table 1 is modeling 10 thickness of magnetic bracket and coil
The inductance of disk 100 and the relation table of Q value.Referring to shown in table 1, applicant has found the magnetism when modeling magnetic bracket 10 in the course of the research
The proportion of substance and ductile material is in 60% to 85% range, when environment temperature is 20 degree, the inductance and Q value of coil panel 100
It can increase with the thickness of modeling magnetic bracket 10, be conducive to the heating efficiency for improving coil panel 100 in this way.However modeling magnetic bracket 10
It is blocked up, but the installation space that will lead to its needs is larger, will definitely increase the body of the electromagnetic cooking appliance using the coil panel 100
Product, and preparation cost can also increase therewith.Therefore comprehensively consider the heating efficiency and manufacturing cost of coil panel 100, this implementation
The thickness range for moulding magnetic bracket 10 is limited in 1.2-2.0mm by example.
Table 1 moulds the inductance of magnetic backing thickness and coil panel and the relation table (environment temperature: 20 DEG C) of Q value
