Abstract
The utility model discloses a single-layer sparsely-wound exciting coil for an induction cooker, and the single-layer sparsely-wound exciting coil comprises a bracket, an exciting coil and a plurality of magnetic strips. The magnetic strips are horizontally distributed on the bracket in a radiated way and inserted into the bracket; the exciting coil is arranged on the surface of the bracket in a single-layer horizontally-wound way; and gaps are reserved between adjacent turns in the exciting coil. As the exciting coil adopts a single-layer horizontally and sparsely wound structure, the exciting coil ensures that wind of a cooling fan passes through the gaps between the turns, so as to greatly improve the ventilation effect and reduce the temperature of the exciting coil; as the gaps are reserved between the turns and conductors can not be in contact with the turns, even if a paint layer of an enameled wire drops out or excess temperature of the exciting coil leads the insulation of the paint layer of the enameled wire to fail, turn-to-turn short circuit can not be caused, so that the problem of turn-to-turn short circuit is thoroughly solved; and moreover, the temperature of the novel exciting coil is about 50 DEG C lower in the circumstance of identical section of the enameled wire, so that the cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of electromagnetic oven, specifically is the magnet exciting coil in a kind of electromagnetic oven.
Background technology
At present, the magnet exciting coil of electromagnetic oven is to be stirred by many enamel covered wires to lump together, the individual layer level close around and be fixed on the PBT magnet exciting coil support that studs with magnetic stripe with curing agent such as epoxy resin.Electromagnetic oven power is up to 2000W, and the impulse current that flows through magnet exciting coil is up to 50A, and the operating voltage at magnet exciting coil two ends is up to more than the 1200V, turn-to-turn voltage up to 50V about.Because high-power, big electric current, high voltage, coil is close to influence the cooling fan ventilation effect around (both the turn-to-turn of magnet exciting coil do not leave the gap be tightly around together).The working temperature of magnet exciting coil can be up to more than 180 ℃.Meet or exceed the limiting temperature of enamelled wire operate as normal.So the ratio that magnet exciting coil burns out is very high.Magnet exciting coil is in processing or use simultaneously, and the wire enamel pull-up falls or excessive temperature very easily causes turn-to-turn short circuit and burns out magnet exciting coil.Want to reduce the temperature of magnet exciting coil, will increase the winding wire cross section,, so promptly increased cost, can not fundamentally solve turn-to-turn short circuit again and the problem of burning magnet exciting coil because the enamel covered wire price is high.Therefore, providing a kind of is that cost is low, permanent durable electromagnetic oven magnet exciting coil safe in utilization becomes the industry technical issues that need to address again.
The utility model content
In order to overcome above-mentioned deficiency, the utility model purpose is to provide that a kind of cost is low, thermal diffusivity good, the individual layer of long service life is dredged around formula electromagnetic oven magnet exciting coil.
To achieve these goals, the technical scheme of the utility model employing is:
Individual layer is dredged around formula electromagnetic oven magnet exciting coil; Include support, magnet exciting coil and a plurality of magnetic stripe; Said a plurality of magnetic stripe with radial horizontal distribution on support; And be embedded in the support, said magnet exciting coil adopts the mode of individual layer level winding to be located at the surface of support, faces mutually in the magnet exciting coil and leaves the gap between the wire turn.
The said gap of facing mutually between the wire turn is 0.1～0.3mm.
The end soldering of the lead-in wire in the said magnet exciting coil has wiring ground ring.
Said magnet exciting coil utilizes epoxy curing agent to be bonded in the surface of support.
The beneficial effect of the utility model: since magnet exciting coil adopts the individual layer level to dredge curl around version; The wind of cooling fan can be passed between every circle coil; Thereby improved ventilation effect greatly, reduced the temperature of magnet exciting coil, but also certain interval has been arranged because of every turn-to-turn; There is not the contact of lead; Even the wire enamel pull-up falls or the too high enamelled wire enamelled coating failure of insulation that causes of magnet exciting coil temperature, can not cause turn-to-turn short circuit yet, thereby fundamentally solve the turn-to-turn short circuit problem; In addition, under the situation in the same cross section of enamelled wire, low about 50 ℃ of novel magnet exciting coil temperature greatly reduces cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, support; 2, magnet exciting coil; 3, magnetic stripe; 4, lead-in wire; 5, wiring ground ring.
Embodiment
As shown in Figure 1; Individual layer is dredged around formula electromagnetic oven magnet exciting coil, includes support 1, magnet exciting coil 2 and a plurality of magnetic stripe 3, said a plurality of magnetic stripes 3 with radial horizontal distribution on support 1; And be embedded in the support 1; Said magnet exciting coil 2 adopts the mode of individual layer level winding to be located at the surface of support 1, faces mutually in the magnet exciting coil 2 and leaves the gap between the wire turn, and the spacing size in this gap is between 0.1～0.3mm.The end soldering of the lead-in wire 4 in the magnet exciting coil 2 has wiring ground ring 5.Magnet exciting coil 2 utilizes epoxy curing agent to be bonded in the surface of support 1.
The above is the preferred implementation of the utility model, can not limit the interest field of the utility model certainly with this.Should be pointed out that for those skilled in the art, the technical scheme of the utility model is made amendment or is equal to replacement, do not break away from the protection range of the utility model.
Claims (4)
1. an individual layer is dredged around formula electromagnetic oven magnet exciting coil; Include support, magnet exciting coil and a plurality of magnetic stripe; Said a plurality of magnetic stripe with radial horizontal distribution on support; And be embedded in the support, it is characterized in that: said magnet exciting coil adopts the mode of individual layer level winding to be located at the surface of support, faces mutually in the magnet exciting coil and leaves the gap between the wire turn.
