本発明は、電磁調理器用コイルセツトの製造方
法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a coil set for an electromagnetic cooker.
従来から、リツツ線をうず巻状に巻回してなる
加熱コイルを、その補強として使用される支持板

ような方法で製造されていた。すなわち、第１
図、第２図に示すように、経方向に長い長孔１を
円周方向に多数分布させた押え板２を支持板３に
対向して配置し、これらの押え板２と支持板３と
の間に、リツツ線、すなわち絶縁ワニスなどで絶

熱コイル４を支持板３上に接着するのである。 BACKGROUND ART Conventionally, a coil set for an electromagnetic cooker has been manufactured by the following method, in which a heating coil made of spirally wound wire is adhered to a support plate used for reinforcement. That is, the first
As shown in FIGS. 2 and 2, a holding plate 2 in which a large number of longitudinally elongated holes 1 are distributed in the circumferential direction is arranged opposite to a supporting plate 3, and these holding plates 2 and 3 are connected to each other. In the meantime, a heating coil 4 is formed by winding a wire, that is, a wire made of twisted wires coated with insulating varnish or the like, in a spiral shape. Next, after preheating these, a thermosetting adhesive is poured into each long hole 1 of the presser plate 2 and applied, and heated again to bond the heating coil 4 onto the support plate 3.
しかしながら、このような従来の製造方法は、
加熱コイル４に対する接着剤の塗布量が必ずしも
一定ではないため塗布むらが起り易く接着力のば
らつきが生ずるという欠点があつた。また、加熱
コイルの両端部４ａ，４ｂがリード線接続のため
に支持板３を貫通して垂下しているが、前記加熱
接着の際に接着剤が両端部４ａ，４ｂに流れ出て
外観的にも好ましくないものとなることがあつ
た。 However, such conventional manufacturing methods
Since the amount of adhesive applied to the heating coil 4 is not necessarily constant, uneven coating tends to occur, resulting in variations in adhesive strength. In addition, both ends 4a and 4b of the heating coil hang down through the support plate 3 for connecting lead wires, but during the heat bonding, adhesive flows out to both ends 4a and 4b, resulting in a poor appearance. Sometimes it became undesirable.
本発明は、上記弊害を除去すべくなされたもの
である。 The present invention has been made to eliminate the above-mentioned disadvantages.
以下、図面について本発明を説明する。 The invention will now be explained with reference to the drawings.
第３図は本発明方法の一実施例を示しており、
図において、支持板５と押え板６とは一定間隔を
おいて対向配置され、中心に挿入された支軸７に
より連結されている。 FIG. 3 shows an embodiment of the method of the present invention,
In the figure, a support plate 5 and a presser plate 6 are arranged facing each other at a constant interval and are connected by a support shaft 7 inserted in the center.
しかして、支持板５上には、押え板６に対置さ
れる前に、予じめ硬化性接着剤８、例えばエポキ
シ樹脂のような熱硬化性の接着剤を所要量塗布す
ると共にセミキユアの状態にしておく。 Therefore, before the support plate 5 is placed opposite to the presser plate 6, a required amount of hardening adhesive 8, for example, a thermosetting adhesive such as epoxy resin, is applied in advance and a semi-cured state is applied. Keep it.
このように予じめ硬化性接着剤８を塗布した支
持板５を押え板６に連結した後、リツツ線９をう

にセミキユア状態の接着剤を完全硬化させる。最
後に、押え板６と支軸７とは除去される。 After the support plate 5 coated with the curable adhesive 8 in advance is connected to the presser plate 6, the wire 9 is wound in a spiral shape to form a heating coil. Thereafter, although not shown, the entire heating coil is heated by a suitable means to bond the heating coil onto the support plate 5, and at the same time, the semi-cured adhesive is completely cured. Finally, the holding plate 6 and the support shaft 7 are removed.

ることがなく、外観上も良好なものが得られる。 According to the method of the present invention, by applying a required amount of curable adhesive 8 in advance on the support plate 5 to which the heating coil is bonded, uneven coating is prevented and variations in adhesive strength are reduced. It can be eliminated. Further, since the curable adhesive 8 is in a semi-cured state, it does not flow out to both ends of the heating coil during heat bonding, and a good appearance can be obtained.
