It is reacted in actual electromagnetic heat protocol:Left side taper (correspondence IGBT switching frequencies are 20Khz) in such as Fig. 5,
Repel each other in rising edge, it is attracting in trailing edge;Such as a taper in Fig. 5 in the curved line of the right, (corresponding to commercial power rectification fundamental wave is
100hz), repel each other in rising edge, attracting in trailing edge, similarly for 200hz, 300hz, 400hz, 500hz etc. harmonic wave is also deposited
In same theory.Therefore it is this attracting, repel each other and just constitute the fundamental of cooking ware vibration, while this vibration is also sent
Corresponding frequencies sound, produces electromagnetic noise.

Embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
Embodiment 1
The present invention provides a kind of cooking ware, including bottom wall and side wall, the bottom wall and side wall one at least within it is outer
Surface is provided with slot segmentation, and the bottom wall and/or side wall are divided into several magnetic inductive blocks by the slot segmentation, single during Electromagnetic Heating
The magnetic inductive block interior energy produces independent circular induced current.
Only it can split to form magnetic inductive block in the bottom wall of cooking ware, can also be only in the side wall segmentation shape of cooking ware
Into magnetic inductive block, it can also split to form magnetic inductive block in the bottom wall and side wall of cooking ware simultaneously, but in general in cooking ware
Bottom wall it is in the majority.
Bottom wall and/or side wall are integrally made up of magnetic conductive material in the present embodiment.
According to Kelvin effect, electric current is merely present in the surface of conductor, and electromagnetic frequency is higher, and electric current is more concentrated on and led
The surface of body.Therefore by bottom wall and side the wall at least within outer surface of one segmentation have multiple magnetic inductive blocks, the big portion of electric current
Divide and flowed in magnetic inductive block, flowed only in gap of the fraction in magnetic inductive block.
The calculation formula of skin depth depth isElectromagnetic Heating working frequency f span is generally
15*103Hz~40*103Hz, the value of the magnetic permeability μ of magnetic inductive block is 4 π * 10-7, conductivityσ=1*10 of magnetic inductive block7S/m。
The present embodiment selects suitable slot segmentation depth bounds according to the calculation formula of skin depth so that magnetic conduction electric current is use up
It may be flowed in magnetic inductive block.According to the above-mentioned parameter of magnetic inductive block, the depth bounds of slot segmentation is set to be set in the present invention
0.79mm~2.2mm.
In electrodynamics, Lorentz force (Lorentz force) is to move the power suffered by the charged particle in electromagnetic field.
According to Lorentz force law, Lorentz force can use equation, referred to as Lorentz force equation, be expressed as:F=q (E+v × B), its
In, F is Lorentz force, and q is the quantity of electric charge of charged particle, and E is electric-field intensity, and v is the speed of charged particle, and B is that magnetic induction is strong
Degree.The integrated form of Lorentz force equation is:
F=∫ V (pE+J × B) dr,
Wherein, V is the volume of integration, and p is charge density, and J is current density, and dr is small element of volume.According to Lorentz
The integrated form of power equation can be seen that in p, J, and in the case that dr keeps constant, Lorentz force F and volume V are proportional,
That is volume V is bigger, and long-range navigation magnetic force F is bigger.The present invention sets the outer surface of cooking ware bottom wall and/or side wall one at least within
There is slot segmentation, the bottom wall and/or side wall are divided into several magnetic inductive blocks by the slot segmentation.It is only right with prior art coil panel
Bottom wall applies long-range navigation magnetic force and compareed, and the volume of conductor is the whole area of bottom wall and the product of skin depth in the prior art;This
Embodiment sets magnetic inductive block by the bottom wall in cooking ware, because most electric current flows in magnetic inductive block, therefore conductor
Volume for area and the skin depth of magnetic inductive block product.Because the gross area of all magnetic inductive blocks is less than the area of whole bottom wall,
Therefore the volume of conductor is less than the volume of conductor in the prior art in the present embodiment, therefore the Lorentz force being subject to also subtracts relatively
It is small, it is corresponding because the vibrating noise produced by long-range navigation magnetic force is also smaller.
The areal extent of magnetic inductive block is greater than or equal to 4.84mm2, less than or equal to 1/4 the bottom of a pan area (with the current the bottom of a pan
Diameter 20cm is calculated, approximately less than 314cm2).If the area of magnetic inductive block is too small and adjacent magnetic inductive block between spacing it is also small
Words, then the conductor volume that coil panel is acted on is still very big, it is impossible to effectively reduce the long-range navigation magnetic force suffered by cooking ware,
Noise produced during cooking ware heating cannot effectively be reduced.If the too small and adjacent magnetic inductive block of the area of magnetic inductive block it
Between spacing it is larger if, region that cooking ware bottom is effectively heated is not enough, it is necessary to which coil panel provides larger heating power.Such as
The area of Tab phenolphthaleinum magnetic patch it is excessive, it is impossible to the effective volume for reducing conductor, the long-range navigation suffered by conductor can not be reduced accordingly
Magnetic force, cannot also effectively reduce noise.The present invention can effectively eliminate the noise of low frequency part, and the low frequency, which refers to, to be less than
1KHz。
Further, since two wires of kindred effect, i.e. two-wire line respectively by alternating current in opposite direction when,
The alternating magnetic field each produced mutually produces vortex on another adjacent wire.This electric current on adjacent wires is at this
The vortex that wire is excited is superimposed with the original operating current of this wire, the actual current in conductor is distributed into section close to phase
Concentrate the side (inner side) of adjacent wire.As shown in Figure 6.By the outer of cooking ware bottom wall and side wall one at least within the present invention
Surface is provided with slot segmentation, and the bottom wall and/or side wall are divided into several magnetic inductive blocks by the slot segmentation, such as Fig. 7 a, 7b for pair
The schematic diagram that cooking ware bottom wall is split:1st, the ring current of magnetic inductive block;2nd, the integral ring-shaped electric current of cooking ware bottom wall;3、
Slot segmentation.
As shown in figure 8, two neighboring magnetic inductive block, because of current direction on the contrary, can be analyzed from kindred effect, schemes upper two
Both adjacent magnetic inductive blocks are attracting, by this neighbouring attracting effect, can offset the overall externally effect of cooking ware electric current circulation
Power.Overall externally active force is also reduced to respective independent magnetic inductive block active force to external world simultaneously, so as to effectively reduce
The overall vibration of cooking ware, reduces vibration, and the electromagnetic noise of generation reduces.
In the present embodiment, the width range of the slot segmentation is 0.79mm~2.2mm.The spacing of adjacent magnetic inductive block can not mistake
It is small, such that being difficult to produce kindred effect between adjacent magnetic inductive block.The spacing of adjacent magnetic inductive block can not be excessive, excessive
Words need coil panel to provide bigger specified heating power, can propose higher requirement to the parameter of coil panel.
The form of heretofore described slot segmentation can have many kinds, be exemplified below several representative.
