Abstract
An improved structure of an electromagnetic heating wire disk comprises a disk frame [1], a heating coil [4], a ferrite magnetic stripe [3], and a power line [5]. A plurality of ferrite magnetic stripes [3] are arranged inside of the disk frame [1] in radiating state; each ferrite magnetic stripe [3] has a notch [2]; a heating coil [4] is installed inside of the notch [2]; at least two notch [2] are arranged by interval along radial position; the corresponding notch [2] between the ferrite magnetic stripes [3] is located at a same circumference; the heating coil [4] closely wound by a plurality of wires and the heating coil [4] closely wound by a plurality of wires are arranged in the notch [2] at a same circumference between the ferrite magnetic stripes [3], which can greatly reduce magnetic leakage and increase inductance amount and improve thermal efficiency.
Description
Technical field
The utility model relates to a kind of electromagnetism heating spool rest that is used for electromagnetic oven, is a kind of structure improved electromagnetism heating spool rest specifically.
Background technology
The used electromagnetism heating spool rest of existing electromagnetic oven mainly is made up of plate rail, heater coil, ferrite magnetic stripe, wherein heater coil adopts enamelled wire one circle circle coiling to form, integral body is ring-type, on the plate rail face, the ferrite magnetic stripe has that some (being generally 6) are fixed in the plate rail radially, the heater coil back side by adhesive bonds.Because heater coil and ferrite magnetic stripe are separated by plate rail, can make leakage magnetic field, influence inductance value, cause the heat efficiency to reduce.
In addition,, in use, be prone to short circuit phenomenon, influence the useful life of electromagnetic oven, and radiating effect be undesirable owing to be close between the line of heater coil and the line.For this reason, the patent No. is 02226111.7 Chinese patent " a kind of novel heater coil disc ", and it has solved this problem better.This heater coil disc includes winding bracket, enamelled wire, wherein by some coil stationary of enamelled wire coiled on winding bracket, leave gap or some strands of coils that closely twine between adjacent two coils and closely leave the gap between the coils of winding with some strands.Therefore, the probability that it both can reduce the phenomenon that is short-circuited between the coil is easy to the heating of enamelled wire again, has strengthened the heating area of enamelled wire, also helps the heat radiation of coil panel self and help pot body to realize the large tracts of land thermally equivalent.But,, finally also influence the heat efficiency owing to also separate between its ferrite magnetic stripe and the heater coil by plate rail.
Summary of the invention
The purpose of this utility model provides a kind of structure improved electromagnetism heating spool rest, and it not only can avoid the heater coil short circuit phenomenon, and can reduce leakage magnetic field, increase inductance value.
The purpose of this utility model can realize by following technical measures:
A kind of structure improved electromagnetism heating spool rest is made up of plate rail, heater coil, ferrite magnetic stripe, power line, and some ferrite magnetic stripes are radiation-like and are laid in the plate rail, and every ferrite magnetic stripe all has recess, and heater coil is installed in the recess.
The recess of every ferrite magnetic stripe has two at least, radially location interval is laid, recess corresponding between the ferrite magnetic stripe is positioned on the same circumference, some strands of heater coils that closely twine with some strands closely the heater coil of winding be contained in respectively between the ferrite magnetic stripe in the recess on the same circumference.
After taking above-mentioned measure, heater coil directly contacts with the ferrite magnetic stripe, can significantly reduce leakage magnetic field, increases inductance value, improves the heat efficiency.And every ferrite magnetic stripe have a recess, directly will separate between the some strands of heater coils that closely twine and the some strands of heater coils that closely twine, easy for installation like this, make easily, both can reduce the probability of the phenomenon that is short-circuited between the heater coil, be easy to the heating of enamelled wire again, also help the heat radiation of heater coil self and help pot body and realize the large tracts of land thermally equivalent, thereby prolong the useful life of electromagnetic oven.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Embodiment
With reference to Fig. 1, a kind of structure improved electromagnetism heating spool rest, form by plate rail [1], heater coil [4], ferrite magnetic stripe [3], power line [5], ferrite magnetic stripe [3] has six, be radiation-like and be laid in plate rail [1] lining, every ferrite magnetic stripe [3] all has recess [2], and heater coil [4] is installed in recess [2] lining.
For reducing the heat radiation of be short-circuited between the heater coil [4] phenomenon and heater coil self, the recess [2] of every ferrite magnetic stripe [3] has two at least, indentation radially location interval is laid, recess [2] corresponding between the ferrite magnetic stripe [3] is positioned on the same circumference, and the some strands of heater coils [4] that closely twine and the some strands of heater coils [4] that closely twine are contained in recess [2] lining on the same circumference between the ferrite magnetic stripe [3] respectively.
