Problem, typical phenomenon is, when with the food such as Stir Vegetable of electromagnetic oven culinary art few water, electromagnetic cooker center little areal extent office
The temperature in portion is too high, and temperature about is relatively low, makes vegetable be easy to part and burns black burnt, and its cooking effect is substantially not as coal gas
Stove;Aforesaid unidirectional winding method refers to that coil is from inside to outside (or anti-along clockwise by a wire (one or multiply)
Clock) single direction coiling, formed multiturn coiling.
Summary of the invention
The technical program to solve the technical problem that and to be to overcome above-mentioned problems of the prior art to carry
The electromagnetic heating wire coil for a kind of magnetic flux utilization rate height and uniformly heated and electromagnetic oven.
In order to solve above-mentioned technical problem, the technical scheme that present patent application uses is: a kind of from coil to coil is oppositely wound
Electromagnetic heating wire coil, including bobbin loader and coil windings, described bobbin loader include some be arranged concentrically circular
The most wide winding slot, be separated by circular block reinforcement between adjacent winding slot, at certain radial direction to all
The circular block reinforcement playing separation winding slot effect opens wide gap, makes all gap be on same straightway, these gap
Being referred to as commutation reducing groove, commutation reducing groove makes to interconnect between each winding slot;Described bobbin loader also includes inlet wire groove and goes out
Wire casing, described inlet wire groove is arranged on the inner circumferential side of the innermost ring winding slot of bobbin loader, and line outlet groove is arranged on the outer shroud of bobbin loader
The outer circumferential side of winding slot.Described coil windings is in being contained in described winding slot, and installs around in same all winding slots
For multilamellar, top layer coil winding at commutation reducing groove reducing and the inner coil that turns around to transform in adjacent winding slot around
Group.
Described circular winding slot is at equal intervals or unequal interval is on-demand is configured, and described each circular block reinforcement is
Wide or the most wide.
The technical program can also be optimized further by techniques below measure:
Described bobbin loader is provided with the magnetic conduction bar loaded from winding slot dorsal part.
The technical program compared with prior art has the advantages that
Some circular winding slots being arranged concentrically of the technical program bobbin loader so that be positioned at same circle in winding slot
The diameter of coil windings identical, coil windings carries out reducing at commutation reducing groove and turns around reversely to install around, and can avoid
The problem that the magnetic flux that the coil of the adjacent turn-to-turn that the unidirectional winding method of tradition causes nearby produces cancels each other, it is possible to increase line
Circle produces the utilization rate of magnetic flux, and make pan the plane the bottom of a pan near there being the corresponding circular annular region of coil windings to produce
The most reverse concentric electric current loop the same number of with coil turn, and the basic phase of size of current of described all electric current loops
With, and then the bottom of a pan is heated properly, the top layer winding of coil windings turns around to be converted into adjacent by commutation reducing groove
Winding slot becomes lower floor's winding, from coil to coil complete multilayer wire coil around process of assembling, it is simple that this kind installs around the simple manufacturing procedure of mode,
Cost is relatively low.
The technical program also provides for a kind of electromagnetic oven with the oppositely wound electromagnetic heating wire coil of aforementioned from coil to coil: it wraps
Include and be provided with concentric circular winding slot, the bobbin loader of commutation reducing groove and coil windings and sequentially coil also in winding slot
Reducing and the electromagnetic heating wire coil reversely installed around that turns around is carried out so that electromagnetic oven magnetic flux utilization rate carries at commutation reducing groove
Rise, it is achieved uniformly heats, and owing to using the electromagnetic heating wire coil of the above-mentioned high magnetic flux utilization rate installing around mode, permissible
Reduce coil turn, reduce the use of metal wire rod, thus reduce the production cost of electromagnetic oven.
