Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below will
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu's ground description, it is clear that described embodiment is a part of embodiment of the invention, rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not having
There is the every other embodiment made and being obtained under the premise of creative work, belong to the present invention
The scope of protection.
Fig. 1 shows a kind of top view of coil panel provided in an embodiment of the present invention, such as Fig. 1 institutes
Show, the coil panel includes support 1 and the coil 2 being attached on the support 1, the coil 2
It is according to the predetermined conductive metal sheet 3 extended around thread path.
Wherein, due to coil 2 be according to the predetermined conductive metal sheet 3 extended around thread path,
The conductive metal sheet 3 in the present embodiment be can be understood as coil 2, support 1 as shown in Figure 2
Can be molded by in-mould injection, coil 2 is attached to support during the injection moulding of support 1
On 1, namely conductive metal sheet 3 is attached on support 1, it is of course also possible to be coil to be formed
Conductive metal sheet be attached on support 1 during the injection moulding of support 1, then again to leading
Electric metal plate processing and fabricating forms conductive metal sheet 3, the conductive gold for being formed in above-mentioned two situations
Category piece 3 can be integrally formed with support 1 so that the coil panel after formation is more frivolous, conducting metal
Piece 3 is appreciated that to be to pass through Digit Control Machine Tool (Computer Numerical by conductive metal sheet
Control, abbreviation CNC) processing or stamping forming mode be made, therefore, it can branch
The conductive metal sheet 3 of various required shapes is formed on frame 1, the Flexible Manufacture of coil 2 is realized,
Additionally by CNC processing or the coil processed of stamping forming mode relative to prior art
Coiling mode speed it is fast, shorten the construction cycle of change coil, and save people
Work cost.
In addition, by conductive metal sheet 3 as coil 2 relative in the prior art using coiling enamel-cover
The mode of line is made, it is to avoid being made coil by the way of coiling enamel-covered wire wire jumper is occurred, scraped
The single problem of the form of bad phenomenon and the coilings such as wound, broken string.
The material of conductive metal sheet 3 is generally metal material, can select good stability, thickness
Tolerance can control the metal material in ± 0.05mm, such as copper, silver or aluminium, in order that
Obtaining coil panel has good thermal diffusivity, and general carrier medium elects beryllium copper as, in addition to realizing
Coil panel it is lightening, conductive metal sheet can be by conductive metal sheet, and such as copper coin is by processing
Or stamping forming mode is made, the thickness range of copper coin namely the thickness model of conductive metal sheet
It is 0.2mm-0.5mm to enclose.
The shape of support 1 is in bowl-shape or discoid, for electric cooker and electric pressure cooking saucepan,
Support 1 is in bowl-shape, and for electromagnetic oven, support 1 is in the form of annular discs, naturally it is also possible to for other
Shape, conductive metal sheet 3 is in spiral of Archimedes shape, what the conductive metal sheet 3 was often enclosed
Width range is 1mm~3mm, the interstice coverage between the adjacent turn of the conductive metal sheet 3
0.5mm~2mm, with while coil electric conductivity is met, it is ensured that coil adjacent turn it
Between insulating properties.Certainly the shape of conductive metal sheet 3, width, thickness, spacing and the number of turns are equal
Can be according to being modified the need for actual product, not to conductive metal sheet in the present embodiment
Shape, width, thickness, spacing and the number of turns are defined.
Wherein, the conductive metal sheet 3 to be formed is processed by CNC, it is adjacent often to enclose conductive metal sheet 3
Between groove be wire casing 4 cross section it is typically rectangular, as shown in figure 3, certainly conducting metal
The shape of piece can also become as the shape of tool and the width of blade installed on CNC are different
Change.
Exposed because the conductive metal sheet 3 in above-mentioned Fig. 1 coil panels is overall, in order that obtaining conductive gold
Category piece 3 is overall will not to be exposed, and enhance the water resistance and oxidation proof propertiess of coil panel, this reality
Applying the coil panel in example can also include by Shooting Technique in film in conductive metal sheet away from institute
The protective layer 5 of the surface covering of support is stated, as shown in figure 4, the protective layer 5 is provided with and exposes
The wiring hole 51 and 52 of the conductive metal sheet binding post, wiring hole 51 and 52 is respectively used to dew
Go out two binding posts of conductive metal sheet 3, the protective layer 5 causes that conductive metal sheet 3 is overall not
Can expose, enhance the water resistance and oxidation proof propertiess of coil panel.Certainly, on protective layer 5
Wiring hole 51 and 52 can not also be included, two binding posts of conductive metal sheet 3 can be respectively
It is that a edges and b edges spill in the two edges of protective layer 5, the present embodiment is not limited thereof,
It is worth noting that, the material of protective layer is also not necessarily limited to plastics, can also can play anti-for other
Oxidation and the material of water resistance, the attachment technique of protective layer are also not necessarily limited to injection, can also adopt
With other techniques such as sprayings.
The embodiment of the present invention additionally provides a kind of electromagnetic heating apparatus, including above-mentioned coil panel.
Above-mentioned coil panel is used on the product of IH mode of heatings, the magnetic line of force pair of IH coils
Interior pot is heated so that food is heated evenly and speed is fast.
