Within enclosing.
Of the invention to propose a kind of coil panel in fact and include the cooking apparatus of the coil panel, which can be electricity
Magnetic stove, electric cooker or pressure cooker etc..On electromagnetic cooking appliance, the description below is introduced by specific embodiment of electromagnetic oven.
With reference to Fig. 2, the present invention proposes a kind of coil panel, including coil panel seat 10 and the winding being installed on coil panel seat 10
Coil 11, the coil panel seat 10 is flat with one, and the winding coil is arranged at described flat；Winding coil 11 includes one the
One winding 11a and the multiple second winding 11b for being arranged at the first winding 11a peripheries, multiple second winding 11b described first around
The group circumferentially-spaced arrangements of 11a, and it is smaller than 50mm between the second winding 11b and the first winding 11a.
Coil tray bottom has magnetic stripe, and usual magnetic stripe is radially set.Magnetic strip arrangements positioned at central area
It is relatively close, and the magnetic stripe distribution density close to marginal portion is less than the distribution density of central area magnetic stripe, so, coil panel week
The magnetic field on side is relatively scattered, and heating effect is poor, cookware bottom is integrally heated uneven.If by the first winding 11a and
Spacing between two winding 11b is arranged to 50mm, then about outside separate first winding 11a30mm, the magnetic of the first winding 11a
Field wire is just laxer, and away from outside the second winding 11b20mm, magnetic induction line is also relatively lax, and at this point, the first winding
The magnetic field that 11a and the second winding 11b is generated can mutually make up, and then can make the magnetic between the first winding 11a and the second winding 11b
Field density obtains relatively by force, so as to form magnetic field white space.
Here, the first winding 11a can be with a variety of coiled fashions, such as square, triangle, ellipse and circle etc..
As the first winding 11a, coiled fashion can exist the second winding 11b in a variety of forms.Second number of winding 11b
It can be for two, three, four and more；In addition, the second winding 11b can be arranged arbitrarily upwards in the first winding 11a peripheries
Cloth can also arrange in ordering rule.Specifically, with reference to Fig. 3 and Fig. 4, under the mode of ordering rule arrangement, when the second winding
When the number of 11b is two, structure can be that U-shaped coiling is set, and around the periphery of the first winding 11a, it can also be direct
The periphery of the first winding 11a is arranged at for annulus.With reference to Fig. 5, when the number of the second winding 11b is three, arrangement mode
The outside that the first winding 11a can be surrounded in 120 ° of angles between any two is set.With reference to Fig. 6, as of the second winding 11b
When number is four, the periphery of the first winding 11a is symmetrically disposed on two-by-two.And so on, when the number of the second winding 11b is one
When determining to increase in scope, the second winding 11b is in be intervally arranged around the periphery of the first winding 11a.
It is generally aligned in the same plane with reference to Fig. 7, the first winding 11a and the second winding 11b, in order to avoid the first winding 11a and the
The gap of two winding 11b generates magnetic field white space, so by the spacing L between the second winding 11b and the first winding 11a
Less than 50mm, such as L can be that 40mm, 30mm, 20mm, 10mm, 5mm etc. or even the first winding 11a and the second winding 11b are supported
It connects also possible, but in order to make magnetic strength evenly, avoids magnetic induction line local closeer and cause to be burned, the first winding 11a's
It is better embodiment that spacing between edge and the edge of the second winding 11b, which takes 20mm to 30mm,.
Technical scheme by setting the first winding 11a and the second winding 11b on flat in coil panel seat 10,
And the second winding 11b the first winding 11a it is circumferentially-spaced arrangement, it can be achieved that multizone heat, in addition, by second around
Spacing between the edge of group 11b and the edge of the first winding 11a is set smaller than 50mm, can avoid the first winding 11a
Edge and the second winding 11b edge between formed electromagnetism white space, so as to improve electromagnetic cooking appliance heating it is equal
Even property.
Cannot be too small in view of the spacing between the first winding 11a and the second winding 11b, it otherwise can cause the first winding
11a is excessively superimposed with the magnetic induction line of the second winding 11b, is burned so as to be easy to cause, and reduces the uniformity of heating.In order to avoid
The situation, in the present embodiment, the spacing between the edge of the edge of the first winding 11a and the second winding 11b is preferably greater than etc.
In 20mm and less than or equal to 30mm.
For the coil that square or triangle is set, due to the presence at turning, so easily forming magnetic strength atenuator region, such as
It is bad that this may result in electromagnetic oven periphery magnetic strength uniformity.In one embodiment, in order to add the center heating zone of coil panel
More regularly and uniform hot, the first winding 11a is set in circular ring shape, so that the magnetic strength that the first winding 11a is generated is evenly.Into
For one step, since the first winding 11a magnetic fields generated are that outwards week is gradually decreased from centre, the first winding 11a's
Diameter cannot be excessive, can not be too small, and diameter, which crosses conference, causes that the magnetic field of the first winding 11a peripheries is excessively weak, and diameter is too small also
Cause heating region smaller, so in this embodiment, the diameter of the first winding 11a is in 80mm to 150mm, preferably
100mm to 120mm.
Based on it is above-mentioned identical the reasons why, the second winding 11b also in circular ring shape set, the diameter of the second winding 11b is in 50mm
To 120mm, preferably 80mm to 100mm.
In another embodiment, in order to consider when cooking operation, the use of entire cooking apparatus or mainly with center
Based on heating zone, supplemented by edge heating area, Gu the diameter of the first winding 11a is set into the diameter more than the second winding 11b,
So that more purposive complete operation and raising work efficiency.
The negligible amounts of second winding 11b may cause the magnetic induction line between two second winding 11b is diluter to dissipate, so as to cause
Heating effect is undesirable.In one embodiment, in order to make the magnetic strength on the first winding 11a peripheries evenly, i.e., described second winding
The quantity of 11b is at 4 to 15, such as 7,8,9,10 etc..
With reference to Fig. 8, it is contemplated that stability when winding coil 11 is installed on coil panel seat 10 is set on coil panel seat 10
It is equipped with the first winding slot 101 to house the first winding 11a and second to the accommodating second winding 11b
First winding 11a and the second winding 11b during installation, are correspondingly arranged in the first winding slot 101 and the second coiling by winding slot 102
In slot 102 so that winding coil 11 is more firm, and is unlikely to off-line occur in operation or mobile utensil and winding coil dissipates
Phenomena such as falling.Here, the first winding 11a can be close around formation or thin around formation；Second winding 11b can also be
It is close around formation or thin around formation.First winding slot 101 and the second winding slot 102 can be directly recessed in coil panel seat
On 10, on the pallet or the concrete structure of support plate etc that can also be opened on coil panel seat 10.
In a further preferred embodiment, in order to winding coil 11 is enable more firmly to be set around in winding slot, pass through by
The depth of two winding slots sets the thickness more than two winding coils, allows entire winding coil 11 that can be placed in winding slot completely
It is interior, so as to be substantially reduced the probability that is scattered of winding coil 11.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every at this
The equivalent structure transformation made under the inventive concept of invention using description of the invention and accompanying drawing content or directly/utilization indirectly
It is included in other related technical areas in the scope of patent protection of the present invention.
