Abstract
An environment-friendly close or sparse winding electromagnetic oven induction wire coil comprises a disc-shaped support with radial supporting ribs, a magnetic strip, a coil, a sleeve and a wiring terminal, wherein the magnetic strip is embedded inside the support, the coil is wound on the support, and the sleeve and the wiring terminal are connected with the ends of the coil. Two ends of each of at least three press trips with lock catches for fixing the coil are respectively inserted into an inner-circle clamp groove and an outer-circle clamp groove of the support and fixed with the support, the inner end and the outer end of the magnetic strip or only the outer end thereof are provided with upward corners, and the main body portion and the upward corners of the magnetic strip are embedded into the support and are in radial distribution together with the supporting ribs. As the ends of the magnetic strip are provided with the upward corners, the wire coil has a magnetic flux leakage prevention function. The coil is fixed by utilizing the press strips with the lock catches to replace adhesion via epoxy resin or specially made glue, thereby being capable of increasing self radiating capacity of the coil greatly, further increasing thermal efficiency of the electronic oven, simultaneously saving materials and reducing energy consumption. Therefore, the environment-friendly close or open winding electromagnetic oven induction wire coil not only is safe, but also is environment-friendly.

Inside and outside two ends of described magnetic stripe or only have upwards turning in the outer end, the main part of magnetic stripe and the turning that makes progress embed internal stent, and radially distribute with buttress, the turning is arranged into internal magnetic ring at the support inner ring in the magnetic stripe, and the outer turning of magnetic stripe is arranged into outer magnetic ring in the support outer ring.
Described magnetic stripe can be inside and outside turning be the right angle [shape magnetic stripe, or inside and outside turning is the U-shaped magnetic stripe of fillets greater than 90 degree, or only have turning upwards in the outer end " the shape magnetic stripe.
Described [the interior turning of shape magnetic stripe and U-shaped magnetic stripe and outer turning be straight flange or respectively with support inner ring, the corresponding arc of radian limit, support outer ring, " the outer turning of shape magnetic stripe is straight flange, or with the corresponding arc of radian limit, support outer ring.
Described with lock withhold bar be [the shape structure, there is dop at both ends, the dop both sides are reversed acanthoid, the middle part has opening.
Described bar upwards bending, the fastening support inner ring withheld with lock at support inner ring place.
Described coil is close to be around on the buttress of surfacing.
Described coil is dredged and is around on the buttress of surfacing.
Described buttress surface has the spirality projection, and coil panel is around in leaving in the groove between the spirality projection.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model has anti-leakage field function because the magnetic stripe end has turning upwards; Adopt the bar fixed coil of withholding with lock to replace epoxy resin or special glue, can improve the heat-sinking capability of coil self greatly, improved the heat efficiency of electromagnetic oven again, can also save material simultaneously, cut down the consumption of energy, safe and environmentally friendly.
