Top winding dish in the utility model embodiment comprises at least two-layer coil, as shown in Figure 2, and the number of turns of coil increases the top winding dish that forms the inverted steps shape from lower floor to upper strata, in order to carry out spacing to the top winding dish of inverted steps shape, the utility model embodiment is designed to the stepped bottom limit rib suitable with the top winding dish by bottom limit rib 12, it is sagging that thereby the top winding dish that makes the inverted steps shape is difficult for, and evenness is better.
The excircle that is this coil panel at the top winding dish shown in Fig. 2 forms the inverted steps shape, when practice, as long as the number of turns of top winding dish coil increases from lower floor to upper strata, can adopt the scheme that the utility model embodiment provides to carry out spacing, for example: the inner periphery of top winding dish can be designed to the inverted steps shape, now the structure of bottom limit rib forms stepped corresponding to the inner periphery direction exactly.Certainly, those skilled in the art also can be designed to the inverted steps shape by the inner periphery of top winding dish and excircle as required, and corresponding bottom limit rib just all forms stepped at inner periphery and excircle direction.
Limiting plate in the utility model embodiment is mainly to carry out spacing to the bottom coil dish, bottom coil dish general mutually concordant with the opening of winding slot bottom, by limiting plate, can carry out spacing, and the bottom coil dish is generally selected single layer coil, certainly, in order to improve efficiency, the bottom coil dish can also be selected the two-layer and two-layer above coil that the number of turns is identical, and can realize by limiting plate spacing.
Drum base 10 in the utility model embodiment comprises inner ring body 13 and outer ring body 14, and limiting plate 11 connects inner ring body 13 and outer ring body 14, for the bottom limit rib be not arranged on limiting plate, this bottom limit rib 12 can be arranged on inner ring body 13, perhaps be arranged on outer ring body 14, also the bottom limit rib can be set on inner ring body 13 and outer ring body 14 simultaneously.For simultaneously, at the bottom limit rib of inner ring body and outer ring body setting, those skilled in the art can couple together both, also can disconnect setting.
Certainly, those skilled in the art also can adopt scheme shown in Fig. 1, and annular muscle is set between inner ring body and outer ring body, and the bottom limit rib connects outer ring body and annular muscle, or the bottom limit rib connects inner ring body and annular muscle.
In order to improve the efficiency of electromagnetic wire coil, the utility model embodiment is provided with the magnetic stripe mounting groove on limiting plate, the one side of ordinary circumstance lower limiting board is used for carrying out spacing to coil, the magnetic stripe mounting groove is arranged on contrary another side, and be provided with magnetic stripe in the magnetic stripe mounting groove, can improve the efficiency of heating surface of this electromagnetic wire coil by the magnet accumulating cap of magnetic stripe.
Embodiment 2:
The utility model embodiment also provides a kind of electromagnetic oven, this electromagnetic oven comprises base and the panel that forms furnace chamber, be provided with electromagnetic wire coil in furnace chamber, this electromagnetic oven electromagnetic wire coil used is the electromagnetic wire coil in above-described embodiment 1, adopt the electromagnetic wire coil in embodiment 1, because coil is comparatively smooth, make specifically comparatively even between each position of electromagnetic wire coil and heated pot, improved the uniformity of electromagnetic oven heating.
Embodiment 3:
The utility model embodiment also discloses a kind of method for winding of electromagnetic wire coil:
At first, as shown in Figure 4, lattice coil dish 30 is started from the outside of winding bracket 20 around, as required at the coil of the specific number of plies of the interior coiling of each winding slot 21, form successively from outside to inside lattice coil dish 30, after last coiling completes, upwards draw at the middle part of outlet terminal 33 winding bracket 20 from Fig. 4 of coil panel.
Secondly, by involutory being arranged on drum base 10 of winding bracket 20 after coiling lattice coil dish 30, specifically as shown in Figure 5, the outlet terminal 33 of coil panel, towards drum base 10, makes outlet terminal 33 pass from the below of drum base 10 when involutory.
Adopt above-mentioned from outside to inside around and involutory scheme, can be so that outlet terminal passes towards the below of electromagnetic wire coil, no longer need outlet terminal, to another direction bending, can directly outlet terminal to be connected to circuit board.
